+Common Cure Rights Commitment
+Version 1.0
+
+Before filing or continuing to prosecute any legal proceeding or claim
+(other than a Defensive Action) arising from termination of a Covered
+License, we commit to extend to the person or entity ('you') accused
+of violating the Covered License the following provisions regarding
+cure and reinstatement, taken from GPL version 3. As used here, the
+term 'this License' refers to the specific Covered License being
+enforced.
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly
+ and finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you
+ have received notice of violation of this License (for any work)
+ from that copyright holder, and you cure the violation prior to 30
+ days after your receipt of the notice.
+
+We intend this Commitment to be irrevocable, and binding and
+enforceable against us and assignees of or successors to our
+copyrights.
+
+Definitions
+
+'Covered License' means the GNU General Public License, version 2
+(GPLv2), the GNU Lesser General Public License, version 2.1
+(LGPLv2.1), or the GNU Library General Public License, version 2
+(LGPLv2), all as published by the Free Software Foundation.
+
+'Defensive Action' means a legal proceeding or claim that We bring
+against you in response to a prior proceeding or claim initiated by
+you or your affiliate.
+
+'We' means each contributor to this repository as of the date of
+inclusion of this file, including subsidiaries of a corporate
+contributor.

+# GlusterFS project Contribution guidelines
+
+## Development Workflow
+
+We follow most of the details as per the [document here](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests). If you are not aware of the github workflow, it is recommended to go through them before continuing here.
+
+
+#### Get the Repository setup
+
+0. Fork Repository
+ - Fork [GlusterFS repository](https://github.com/gluster/glusterfs/fork).
+
+1. Clone Repository
+ - Clone the glusterfs repo freshly from github using below steps.
+
+```
+ git clone git@github.com:${username}/glusterfs.git
+ cd glusterfs/
+ git remote add upstream git@github.com:gluster/glusterfs.git
+```
+
+About two tasks are one time for the life time. You can continue to use the same repository for all the work in future.
+
+#### Development & Other flows
+
+0. Issue:
+ - Make sure there is an issue filed for the task you are working on.
+ - If it is not filed, open the issue with all the description.
+ - If it is a bug fix, add label "Type:Bug".
+ - If it is an RFC, provide all the documentation, and request for "DocApproved", and "SpecApproved" label.
+
+1. Code:
+ - Start coding
+ - Build and test locally
+ - Make sure clang-format is installed and is run on the patch.
+
+2. Keep up-to-date
+ - GlusterFS is a large project with many developers, so there would be one or the other patch everyday.
+ - It is critical for developer to be up-to-date with `devel` repo to be Conflict-Free when PR is opened.
+ - Git provides many options to keep up-to-date, below is one of them
+```
+ git fetch upstream
+ git rebase upstream/devel
+```
+ - It is recommended you keep pushing to your repo every day, so you don't loose any work.
+ - It can be done by `./rfc.sh` (or `git push origin HEAD:issueNNN`)
+
+2. Commit Message / PR description:
+ - The name of the branch on your personal fork can start with issueNNNN, followed by anything of your choice.
+ - PRs continue to have the title of format "component: \<title\>", like it is practiced now.
+ - When you open a PR, having a reference Issue for the commit is mandatory in GlusterFS.
+ - Commit message can have, either `Fixes: #NNNN` or `Updates: #NNNN` in a separate line in the commit message.
+ - Here, NNNN is the Issue ID in glusterfs repository.
+ - Each commit needs the author to have the "Signed-off-by: Name \<email\>" line.
+ - Can do this by `-s` option for `git commit`.
+ - If the PR is not ready for review, apply the label `work-in-progress`.
+ - Check the availability of "Draft PR" is present for you, if yes, use that instead.
+
+3. Tests:
+ - All the required smoke tests would be auto-triggered.
+ - Developers get a chance to retrigger the smoke tests using **"/recheck smoke"** as comment.
+ - The "regression" tests would be triggered by a comment **"/run regression"** from developers in the [@gluster-maintainers](https://github.com/orgs/gluster/teams/gluster-maintainers) group.
+ - Ask for help as comment in PR if you have any questions about the process!
+
+4. Review Process:
+ - `+2` : is equivalent to "Approve" from the people in the maintainer's group.
+ - `+1` : can be given by a maintainer/reviewer by explicitly stating that in the comment.
+ - `-1` : provide details on required changes and pick "Request Changes" while submitting your review.
+ - `-2` : done by adding the `DO-NOT-MERGE` label.
+
+ - Any further discussions can happen as comments in the PR.
+
+5. Making changes:
+ - There are 2 approaches to submit changes done after addressing review comments.
+ - Commit changes as a new commit on top of the original commits in the branch, and push the changes to same branch (issueNNNN)
+ - Commit changes into the same commit with `--amend` option, and do a push to the same branch with `--force` option.
+
+6. Merging:
+ - GlusterFS project follows 'Squash and Merge' method
+ - This is mainly to preserve the historic Gerrit method of one patch in `git log` for one URL link.
+ - This also makes every merge a complete patch, which has passed all tests.
+ - The merging of the patch is expected to be done by the maintainers.
+ - It can be done when all the tests (smoke and regression) pass.
+ - When the PR has 'Approved' flag from corresponding maintainer.
+ - If you feel there is delay, feel free to add a comment, discuss the same in Slack channel, or send email.
+

- GNU GENERAL PUBLIC LICENSE
- Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
- The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works. By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users. We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors. You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
- To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights. Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received. You must make sure that they, too, receive
-or can get the source code. And you must show them these terms so they
-know their rights.
-
- Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
- For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software. For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
- Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so. This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software. The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable. Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products. If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
- Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary. To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- TERMS AND CONDITIONS
-
- 0. Definitions.
-
- "This License" refers to version 3 of the GNU General Public License.
-
- "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
- "The Program" refers to any copyrightable work licensed under this
-License. Each licensee is addressed as "you". "Licensees" and
-"recipients" may be individuals or organizations.
-
- To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy. The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
- A "covered work" means either the unmodified Program or a work based
-on the Program.
-
- To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy. Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
- To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies. Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
- An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License. If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
- 1. Source Code.
-
- The "source code" for a work means the preferred form of the work
-for making modifications to it. "Object code" means any non-source
-form of a work.
-
- A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
- The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form. A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
- The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities. However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work. For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
- The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
- The Corresponding Source for a work in source code form is that
-same work.
-
- 2. Basic Permissions.
-
- All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met. This License explicitly affirms your unlimited
-permission to run the unmodified Program. The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work. This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
- You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force. You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright. Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
- Conveying under any other circumstances is permitted solely under
-the conditions stated below. Sublicensing is not allowed; section 10
-makes it unnecessary.
-
- 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
- No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
- When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
- 4. Conveying Verbatim Copies.
-
- You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
- You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
- 5. Conveying Modified Source Versions.
-
- You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
- a) The work must carry prominent notices stating that you modified
- it, and giving a relevant date.
-
- b) The work must carry prominent notices stating that it is
- released under this License and any conditions added under section
- 7. This requirement modifies the requirement in section 4 to
- "keep intact all notices".
-
- c) You must license the entire work, as a whole, under this
- License to anyone who comes into possession of a copy. This
- License will therefore apply, along with any applicable section 7
- additional terms, to the whole of the work, and all its parts,
- regardless of how they are packaged. This License gives no
- permission to license the work in any other way, but it does not
- invalidate such permission if you have separately received it.
-
- d) If the work has interactive user interfaces, each must display
- Appropriate Legal Notices; however, if the Program has interactive
- interfaces that do not display Appropriate Legal Notices, your
- work need not make them do so.
-
- A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit. Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
- 6. Conveying Non-Source Forms.
-
- You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
- a) Convey the object code in, or embodied in, a physical product
- (including a physical distribution medium), accompanied by the
- Corresponding Source fixed on a durable physical medium
- customarily used for software interchange.
-
- b) Convey the object code in, or embodied in, a physical product
- (including a physical distribution medium), accompanied by a
- written offer, valid for at least three years and valid for as
- long as you offer spare parts or customer support for that product
- model, to give anyone who possesses the object code either (1) a
- copy of the Corresponding Source for all the software in the
- product that is covered by this License, on a durable physical
- medium customarily used for software interchange, for a price no
- more than your reasonable cost of physically performing this
- conveying of source, or (2) access to copy the
- Corresponding Source from a network server at no charge.
-
- c) Convey individual copies of the object code with a copy of the
- written offer to provide the Corresponding Source. This
- alternative is allowed only occasionally and noncommercially, and
- only if you received the object code with such an offer, in accord
- with subsection 6b.
-
- d) Convey the object code by offering access from a designated
- place (gratis or for a charge), and offer equivalent access to the
- Corresponding Source in the same way through the same place at no
- further charge. You need not require recipients to copy the
- Corresponding Source along with the object code. If the place to
- copy the object code is a network server, the Corresponding Source
- may be on a different server (operated by you or a third party)
- that supports equivalent copying facilities, provided you maintain
- clear directions next to the object code saying where to find the
- Corresponding Source. Regardless of what server hosts the
- Corresponding Source, you remain obligated to ensure that it is
- available for as long as needed to satisfy these requirements.
-
- e) Convey the object code using peer-to-peer transmission, provided
- you inform other peers where the object code and Corresponding
- Source of the work are being offered to the general public at no
- charge under subsection 6d.
-
- A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
- A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling. In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage. For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product. A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
- "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source. The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
- If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information. But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
- The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed. Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
- Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
- 7. Additional Terms.
-
- "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law. If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
- When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it. (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.) You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
- Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
- a) Disclaiming warranty or limiting liability differently from the
- terms of sections 15 and 16 of this License; or
-
- b) Requiring preservation of specified reasonable legal notices or
- author attributions in that material or in the Appropriate Legal
- Notices displayed by works containing it; or
-
- c) Prohibiting misrepresentation of the origin of that material, or
- requiring that modified versions of such material be marked in
- reasonable ways as different from the original version; or
-
- d) Limiting the use for publicity purposes of names of licensors or
- authors of the material; or
-
- e) Declining to grant rights under trademark law for use of some
- trade names, trademarks, or service marks; or
-
- f) Requiring indemnification of licensors and authors of that
- material by anyone who conveys the material (or modified versions of
- it) with contractual assumptions of liability to the recipient, for
- any liability that these contractual assumptions directly impose on
- those licensors and authors.
-
- All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10. If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term. If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
- If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
- Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
- 8. Termination.
-
- You may not propagate or modify a covered work except as expressly
-provided under this License. Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
- However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
- Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
- Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License. If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
- 9. Acceptance Not Required for Having Copies.
-
- You are not required to accept this License in order to receive or
-run a copy of the Program. Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance. However,
-nothing other than this License grants you permission to propagate or
-modify any covered work. These actions infringe copyright if you do
-not accept this License. Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
- 10. Automatic Licensing of Downstream Recipients.
-
- Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License. You are not responsible
-for enforcing compliance by third parties with this License.
-
- An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations. If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
- You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License. For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
- 11. Patents.
-
- A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based. The
-work thus licensed is called the contributor's "contributor version".
-
- A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version. For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
- Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
- In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement). To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
- If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients. "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
- If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
- A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License. You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
- Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
- 12. No Surrender of Others' Freedom.
-
- If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all. For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
- 13. Use with the GNU General Public License.
-
- Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU General Public License into a single
-combined work, and to convey the resulting work. The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
- 14. Revised Versions of this License.
-
- The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
- Each version is given a distinguishing version number. If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation. If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
- If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
- Later license versions may give you additional or different
-permissions. However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
- 15. Disclaimer of Warranty.
-
- THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
- 16. Limitation of Liability.
-
- IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
- 17. Interpretation of Sections 15 and 16.
-
- If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This program is free software: you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation, either version 3 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program. If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
- If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
- <program> Copyright (C) <year> <name of author>
- This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
- You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<http://www.gnu.org/licenses/>.
-
- The GNU General Public License does not permit incorporating your program
-into proprietary programs. If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library. If this is what you want to do, use the GNU Lesser General
-Public License instead of this License. But first, please read
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.

+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the

+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+ This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+ 0. Additional Definitions.
+
+ As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+ "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+ An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+ A "Combined Work" is a work produced by combining or linking an
+Application with the Library. The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+ The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+ The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+ 1. Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+ 2. Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+ a) under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs
+ whatever part of its purpose remains meaningful, or
+
+ b) under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
+
+ 3. Object Code Incorporating Material from Library Header Files.
+
+ The object code form of an Application may incorporate material from
+a header file that is part of the Library. You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+ a) Give prominent notice with each copy of the object code that the
+ Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the object code with a copy of the GNU GPL and this license
+ document.
+
+ 4. Combined Works.
+
+ You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+ a) Give prominent notice with each copy of the Combined Work that
+ the Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
+
+ c) For a Combined Work that displays copyright notices during
+ execution, include the copyright notice for the Library among
+ these notices, as well as a reference directing the user to the
+ copies of the GNU GPL and this license document.
+
+ d) Do one of the following:
+
+ 0) Convey the Minimal Corresponding Source under the terms of this
+ License, and the Corresponding Application Code in a form
+ suitable for, and under terms that permit, the user to
+ recombine or relink the Application with a modified version of
+ the Linked Version to produce a modified Combined Work, in the
+ manner specified by section 6 of the GNU GPL for conveying
+ Corresponding Source.
+
+ 1) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (a) uses at run time
+ a copy of the Library already present on the user's computer
+ system, and (b) will operate properly with a modified version
+ of the Library that is interface-compatible with the Linked
+ Version.
+
+ e) Provide Installation Information, but only if you would otherwise
+ be required to provide such information under section 6 of the
+ GNU GPL, and only to the extent that such information is
+ necessary to install and execute a modified version of the
+ Combined Work produced by recombining or relinking the
+ Application with a modified version of the Linked Version. (If
+ you use option 4d0, the Installation Information must accompany
+ the Minimal Corresponding Source and Corresponding Application
+ Code. If you use option 4d1, you must provide the Installation
+ Information in the manner specified by section 6 of the GNU GPL
+ for conveying Corresponding Source.)
+
+ 5. Combined Libraries.
+
+ You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+ a) Accompany the combined library with a copy of the same work based
+ on the Library, uncombined with any other library facilities,
+ conveyed under the terms of this License.
+
+ b) Give prominent notice with the combined library that part of it
+ is a work based on the Library, and explaining where to find the
+ accompanying uncombined form of the same work.
+
+ 6. Revised Versions of the GNU Lesser General Public License.
+
+ The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+ If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+GlusterFS Maintainers
+=====================
+
+The intention of this file is not to establish who owns what portions of the
+code base, but to provide a set of names that developers can consult when they
+have a question about a particular subset and also to provide a set of names
+to be CC'd when submitting a patch to obtain appropriate review.
+
+In general, if you have a question about inclusion of a patch, you should
+consult gluster-devel@gluster.org and not any specific individual privately.
+
+Descriptions of section entries:
+
+ M: Main contact that knows and takes care of this area
+ L: Mailing list that is relevant to this area
+ W: Web-page with status/info
+ Q: Patchwork web based patch tracking system site
+ T: SCM tree type and location. Type is one of: git, hg, quilt, stgit.
+ S: Status, one of the following:
+ Supported: Someone is actually paid to look after this.
+ Maintained: Someone actually looks after it.
+ Odd Fixes: It has a maintainer but they don't have time to do
+ much other than throw the odd patch in. See below.
+ Orphan: No current maintainer [but maybe you could take the
+ role as you write your new code].
+ Obsolete: Old code. Something tagged obsolete generally means
+ it has been replaced by a better system and you
+ should be using that.
+ F: Files and directories with wildcard patterns.
+ A trailing slash includes all files and subdirectory files.
+ F: drivers/net/ all files in and below drivers/net
+ F: drivers/net/* all files in drivers/net, but not below
+ F: */net/* all files in "any top level directory"/net
+ One pattern per line. Multiple F: lines acceptable.
+ X: Files and directories that are NOT maintained, same rules as F:
+ Files exclusions are tested before file matches.
+ Can be useful for excluding a specific subdirectory, for instance:
+ F: net/
+ X: net/ipv6/
+ matches all files in and below net excluding net/ipv6/
+ K: Keyword perl extended regex pattern to match content in a
+ patch or file. For instance:
+ K: of_get_profile
+ matches patches or files that contain "of_get_profile"
+ K: \b(printk|pr_(info|err))\b
+ matches patches or files that contain one or more of the words
+ printk, pr_info or pr_err
+ One regex pattern per line. Multiple K: lines acceptable.
+ P: Peer for a component

+# Gluster
+ Gluster is a software defined distributed storage that can scale to several
+ petabytes. It provides interfaces for object, block and file storage.
+
+## Development
+ The development workflow is documented in [Contributors guide](CONTRIBUTING.md)
+
+## Documentation
+ The Gluster documentation can be found at [Gluster Docs](http://docs.gluster.org).
+
+## Deployment
+ Quick instructions to build and install can be found in [INSTALL](INSTALL) file.
+
+## Testing
+
+ GlusterFS source contains some functional tests under `tests/` directory. All
+ these tests are run against every patch submitted for review. If you want your
+ patch to be tested, please add a `.t` test file as part of your patch submission.
+ You can also submit a patch to only add a `.t` file for the test case you are
+ aware of.
+
+ To run these tests, on your test-machine, just run `./run-tests.sh`. Don't run
+ this on a machine where you have 'production' glusterfs is running, as it would
+ blindly kill all gluster processes in each runs.
+
+ If you are sending a patch, and want to validate one or few specific tests, then
+ run a single test by running the below command.
+
+```
+ bash# /bin/bash ${path_to_gluster}/tests/basic/rpc-coverage.t
+```
+
+ You can also use `prove` tool if available in your machine, as follows.
+
+```
+ bash# prove -vmfe '/bin/bash' ${path_to_gluster}/tests/basic/rpc-coverage.t
+```
+
+
+## Maintainers
+ The list of Gluster maintainers is available in [MAINTAINERS](MAINTAINERS) file.
+
+## License
+ Gluster is dual licensed under [GPLV2](COPYING-GPLV2) and [LGPLV3+](COPYING-LGPLV3).
+
+ Please visit the [Gluster Home Page](http://www.gluster.org/) to find out more about Gluster.

+This is an example application which uses libgfapi. It is
+a complete autotools based build system which demonstrates the
+required changes in configure.ac, Makefile.am etc to successfuly
+detect for and build an application against libgfapi.
+
+There are two approaches to building a libgfapi based application:
+
+1. In the presence of pkg-config in your build system.
+This is the recommended approach which is also used in this example.
+For this approach to work, you need to build glusterfs by passing
+--pkgconfigdir=/usr/lib64/pkgconfig (or the appropriate directory)
+in your distro. This already happens if you build RPMs with the
+glusterfs.spec provided in glusterfs.git. You will also need to
+install glusterfs-api RPM.
+
+2. In the absence of pkg-config in your build system.
+Make sure your LDFLAGS includes -L/path/to/lib where libgfapi.so is
+installed and -I/path/to/include/glusterfs where the 'api' directory
+containing the headers are available.
+
+glfsxmp.c
+=========
+
+glfsxmp.c is an example application which uses libgfapi
+
+Compilation Steps For glfsxmp.c
+===============================
+
+1. $./autogen.sh
+2. $./configure
+
+Note: Before running ./configure , as mentioned above, you need to
+ take care of #1 or #2 i.e. pkg-config path or LDFLAGS and
+ -I/<path> with correct values.
+
+3. $make glfsxmp

+/* GLFS OBJECT BASED OPERATIONS
+ *
+ * The following APIs are introduced to provide an API framework that can work
+ * with gluster objects (files and directories), instead of absolute paths.
+ *
+ * The following API set can be related to the POSIX *at interfaces (like
+ * openat (2)). The intention of these APIs is to be able to operate based
+ * on parent object and looking up or creating child objects within, OR to be
+ * used on the actual object thus looked up or created, and retrieve information
+ * regarding the same.
+ *
+ * The APIs also provide for generating an opaque invariant handle to the
+ * object, that can later be used to lookup the object, instead of the regular
+ * glfs_h_* variants. The APIs that provide this behaviour are,
+ * glfs_h_extract_handle and glfs_h_create_from_handle.
+ *
+ * The object handles can be transitioned to fd based operations as supported
+ * by glfs.h calls, using the glfs_h_open call. This provides a way to move
+ * from objects to fd's akin to moving from path to fd for required operations.
+ *
+ * NOTE: The opaque invariant handle is the GFID of the object in reality, but
+ * maintained as an opaque data value, for potential internal changes to the
+ * same without impacting the caller.
+ *
+ * NOTE: Currently looking up an object can create multiple object handles to
+ * the same, i.e distinct glfs_object *. Hence each such looked up or received
+ * handle from other calls, would need to be closed. In the future, for a given
+ * object these pointers would be the same, and an ease of use API to forget all
+ * instances of this bject would be provided (instead of a per lookup close).
+ * This should not change the APIs in their current form.

+ SYNOPSIS
+
+ glfs_h_poll_upcall: Poll for upcall events given a 'glfs' object.
+
+ DESCRIPTION
+
+ This API is used to poll for upcall events stored in the
+ upcall list. Current users of this API is NFS-Ganesha.
+ In case of any event received, it will be mapped appropriately
+ into 'glfs_upcall' along with the handle('glfs_object') to be
+ passed to NFS-Ganesha.
+
+ In case of success, applications need to check the value of
+ cbk->handle to be NON NULL before processing the upcall
+ events.
+
+ PARAMETERS
+
+ @fs: glfs object to poll the upcall events for
+ @cbk: Pointer that will contain an upcall event for use by the application.
+ Application is responsible for free'ing the structure with glfs_free().
+
+ RETURN VALUES
+
+ 0 : Success.
+ -1 : Error condition, mostly due to out of memory.

+ SYNOPSIS
+
+ glfs_new: Create a new 'virtual mount' object.
+
+ DESCRIPTION
+
+ This is most likely the very first function you will use. This function
+ will create a new glfs_t (virtual mount) object in memory.
+
+ On this newly created glfs_t, you need to be either set a volfile path
+ (glfs_set_volfile) or a volfile server (glfs_set_volfile_server).
+
+ The glfs_t object needs to be initialized with glfs_init() before you
+ can start issuing file operations on it.
+
+ PARAMETERS
+
+ @volname: Name of the volume. This identifies the server-side volume and
+ the fetched volfile (equivalent of --volfile-id command line
+ parameter to glusterfsd). When used with glfs_set_volfile() the
+ @volname has no effect (except for appearing in log messages).
+
+ RETURN VALUES
+
+ NULL : Out of memory condition.
+ Others : Pointer to the newly created glfs_t virtual mount object.

+ glfs_set_volfile_server: Specify the list of addresses for management server.
+
+ DESCRIPTION
+
+ This function specifies the list of addresses for the management server
+ (glusterd) to connect, and establish the volume configuration. The @volname
+ parameter passed to glfs_new() is the volume which will be virtually
+ mounted as the glfs_t object. All operations performed by the CLI at
+ the management server will automatically be reflected in the 'virtual
+ mount' object as it maintains a connection to glusterd and polls on
+ configuration change notifications.
+
+ This is incompatible with glfs_set_volfile().
+
+ PARAMETERS
+
+ @fs: The 'virtual mount' object to be configured with the volume
+ specification file.
+
+ @transport: String specifying the transport used to connect to the
+ management daemon. Specifying NULL will result in the
+ usage of the default (tcp) transport type. Permitted
+ values are "tcp" or "unix".
+
+ @host: String specifying the address where to find the management daemon.

+ This would either be

+ - ASCII (e.g : "192.168.22.1") or
+ - Socket path (e.g : "/var/run/glusterd.socket")
+
+ NOTE: This API is special, multiple calls to this function with different
+ volfile servers, port or transport-type would create a list of volfile
+ servers which would be polled during `volfile_fetch_attempts()`
+
+ @port: The TCP port number where gluster management daemon is listening.
+ Specifying 0 uses the default port number GF_DEFAULT_BASE_PORT.
+ This parameter is unused if you are using a UNIX domain socket.

+ GF_GET_LEASE: Get the lease type currently present on the file,
+ lease.lease_type will contain GF_RD_LEASE
+ or GF_RW_LEASE or 0 if no leases.
+ GF_SET_LEASE: Set the lease of given lease.lease_type on the file.
+ GF_UNLK_LEASE: Unlock the lease present on the given fd.
+ Note that the every lease request should have
+ a corresponding unlk_lease.
+
+ @lease.lease_type - Can be one of the following values
+ GF_RD_LEASE: Read lease on a file, shared lease.
+ GF_RW_LEASE: Read-Write lease on a file, exclusive lease.
+
+ @lease.lease_id - A unique identification of lease, 128bits.

-dnl
-dnl This macros will create a local "_stdint.h" or the headerfile given as
-dnl an argument. In many cases that file will just "#include <stdint.h>"
-dnl or "#include <inttypes.h>", while in other environments it will provide
-dnl the set of basic 'stdint's definitions/typedefs:
-dnl int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
-dnl int_least32_t.. int_fast32_t.. intmax_t
-dnl which may or may not rely on the definitions of other files,
-dnl or using the AC_CHECK_SIZEOF macro to determine the actual
-dnl sizeof each type.
-dnl
-dnl if your header files require the stdint-types you will want to create an
-dnl installable file mylib-int.h that all your other installable header
-dnl may include. So if you have a library package named "mylib", just use
-dnl AX_CREATE_STDINT_H(mylib-int.h)
-dnl in configure.ac and go to install that very header file in Makefile.am
-dnl along with the other headers (mylib.h) - and the mylib-specific headers
-dnl can simply use "#include <mylib-int.h>" to obtain the stdint-types.
-dnl
-dnl Remember, if the system already had a valid <stdint.h>, the generated
-dnl file will include it directly. No need for fuzzy HAVE_STDINT_H things...

- * Original:
- * Patrick Powell Tue Apr 11 09:48:21 PDT 1995
- * A bombproof version of doprnt (dopr) included.
- * Sigh. This sort of thing is always nasty do deal with. Note that
- * the version here does not include floating point...
- *
- * snprintf() is used instead of sprintf() as it does limit checks
- * for string length. This covers a nasty loophole.
- *
- * The other functions are there to prevent NULL pointers from
- * causing nast effects.
- *
- * More Recently:
- * Brandon Long <blong@fiction.net> 9/15/96 for mutt 0.43
- * This was ugly. It is still ugly. I opted out of floating point
- * numbers, but the formatter understands just about everything
- * from the normal C string format, at least as far as I can tell from
- * the Solaris 2.5 printf(3S) man page.
- *
- * Brandon Long <blong@fiction.net> 10/22/97 for mutt 0.87.1
- * Ok, added some minimal floating point support, which means this
- * probably requires libm on most operating systems. Don't yet
- * support the exponent (e,E) and sigfig (g,G). Also, fmtint()
- * was pretty badly broken, it just wasn't being exercised in ways
- * which showed it, so that's been fixed. Also, formated the code
- * to mutt conventions, and removed dead code left over from the
- * original. Also, there is now a builtin-test, just compile with:
- * gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm
- * and run snprintf for results.
- *
- * Thomas Roessler <roessler@guug.de> 01/27/98 for mutt 0.89i
- * The PGP code was using unsigned hexadecimal formats.
- * Unfortunately, unsigned formats simply didn't work.
- *
- * Michael Elkins <me@cs.hmc.edu> 03/05/98 for mutt 0.90.8
- * The original code assumed that both snprintf() and vsnprintf() were
- * missing. Some systems only have snprintf() but not vsnprintf(), so
- * the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF.
- *
- * Andrew Tridgell (tridge@samba.org) Oct 1998
- * fixed handling of %.0f
- * added test for HAVE_LONG_DOUBLE
- *
- * Russ Allbery <rra@stanford.edu> 2000-08-26
- * fixed return value to comply with C99
- * fixed handling of snprintf(NULL, ...)
- *
- * Niels Möller <nisse@lysator.liu.se> 2004-03-05
- * fixed calls to isdigit to use unsigned char.
- * fixed calls to va_arg; short arguments are always passed as int.

+# AC_PROG_MKDIR_P
+# ---------------
+# Check whether `mkdir -p' is known to be thread-safe, and fall back to
+# install-sh -d otherwise.
+#
+# Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
+# created by `make install' are always world readable, even if the
+# installer happens to have an overly restrictive umask (e.g. 077).
+# This was a mistake. There are at least two reasons why we must not
+# use `-m 0755':
+# - it causes special bits like SGID to be ignored,
+# - it may be too restrictive (some setups expect 775 directories).
+#
+# Do not use -m 0755 and let people choose whatever they expect by

+# We cannot accept any implementation of `mkdir' that recognizes `-p'.
+# Some implementations (such as Solaris 8's) are vulnerable to race conditions:
+# if a parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'
+# concurrently, both version can detect that a/ is missing, but only
+# one can create it and the other will error out. Consequently we
+# restrict ourselves to known race-free implementations.
+#
+# Automake used to define mkdir_p as `mkdir -p .', in order to
+# allow $(mkdir_p) to be used without argument. As in
+# $(mkdir_p) $(somedir)
+# where $(somedir) is conditionally defined. However we don't do
+# that for MKDIR_P.
+# 1. before we restricted the check to GNU mkdir, `mkdir -p .' was
+# reported to fail in read-only directories. The system where this
+# happened has been forgotten.
+# 2. in practice we call $(MKDIR_P) on directories such as
+# $(MKDIR_P) "$(DESTDIR)$(somedir)"
+# and we don't want to create $(DESTDIR) if $(somedir) is empty.
+# To support the latter case, we have to write
+# test -z "$(somedir)" || $(MKDIR_P) "$(DESTDIR)$(somedir)"
+# so $(MKDIR_P) always has an argument.
+# We will have better chances of detecting a missing test if
+# $(MKDIR_P) complains about missing arguments.
+# 3. $(MKDIR_P) is named after `mkdir -p' and we don't expect this
+# to accept no argument.
+# 4. having something like `mkdir .' in the output is unsightly.
+#
+# On NextStep and OpenStep, the `mkdir' command does not

+ Suppose there is a byte with all zeros. Any carry bits
+ propagating from its left will fall into the hole at its
+ least significant bit and stop. Since there will be no
+ carry from its most significant bit, the LSB of the
+ byte to the left will be unchanged, and the zero will be
+ detected.
+
+ 2) Is this worthwhile? Will it ignore everything except
+ zero bytes? Suppose every byte of LONGWORD has a bit set
+ somewhere. There will be a carry into bit 8. If bit 8
+ is set, this will carry into bit 16. If bit 8 is clear,
+ one of bits 9-15 must be set, so there will be a carry
+ into bit 16. Similarly, there will be a carry into bit
+ 24. If one of bits 24-30 is set, there will be a carry
+ into bit 31, so all of the hole bits will be changed.
+
+ The one misfire occurs when bits 24-30 are clear and bit
+ 31 is set; in this case, the hole at bit 31 is not
+ changed. If we had access to the processor carry flag,
+ we could close this loophole by putting the fourth hole
+ at bit 32!
+
+ So it ignores everything except 128's, when they're aligned
+ properly.
+
+ 3) But wait! Aren't we looking for C, not zero?
+ Good point. So what we do is XOR LONGWORD with a longword,

+ * Unfortunately, on some target/compiler combinations, the generated assembly is sub-optimal.
+ * The below switch allow to select different access method for improved performance.
+ * Method 0 (default) : use `memcpy()`. Safe and portable.
+ * Method 1 : `__packed` statement. It depends on compiler extension (ie, not portable).
+ * This method is safe if your compiler supports it, and *generally* as fast or faster than `memcpy`.
+ * Method 2 : direct access. This method doesn't depend on compiler but violate C standard.
+ * It can generate buggy code on targets which do not support unaligned memory accesses.
+ * But in some circumstances, it's the only known way to get the most performance (ie GCC + ARMv6)
+ * See http://stackoverflow.com/a/32095106/646947 for details.

+
+xxHash is an extremely fast Hash algorithm, running at RAM speed limits.
+It also successfully passes all tests from the SMHasher suite.
+

+Q.Score is a measure of quality of the hash function.
+It depends on successfully passing SMHasher test set.
+10 is a perfect score.
+
+A 64-bit version, named XXH64, is available since r35.
+It offers much better speed, but for 64-bit applications only.

-* Authentication is provided by two modules addr and login. Login based authentication uses username/password from client for authentication. Each module returns either ACCEPT, REJCET or DONT_CARE. DONT_CARE is returned if the input authentication information to the module is not concerned to its working. The theory behind authentication is that "none of the auth modules should return REJECT and atleast one of them should return ACCEPT"
-
-* Currently all the authentication related information is passed un-encrypted over the network from client to server.
-
-----------------------------------------------------------------------------------------------------
-* options provided in protocol/client:
- * for username/password based authentication:
- option username <username>
- option password <password>
- * client can have only one set of username/password
- * for addr based authentication:
- * no options required in protocol/client. Client has to bind to privileged port (port < 1024 ) which means the process in which protocol/client is loaded has to be run as root.
-
-----------------------------------------------------------------------------------------------------
-* options provided in protocol/server:
- * for username/password based authentication:
- option auth.login.<brick>.allow [comma seperated list of usernames using which clients can connect to volume <brick>]
- option auth.login.<username>.password <password> #specify password <password> for username <username>
- * for addr based authentication:
- option auth.addr.<brick>.allow [comma seperated list of ip-addresses/unix-paths from which clients are allowed to connect to volume <brick>]
- option auth.addr.<brick>.reject [comma seperated list of ip-addresses/unix-paths from which clients are not allowed to connect to volume <brick>]
- * negation operator '!' is used to invert the sense of matching.
- Eg., option auth.addr.brick.allow !a.b.c.d #do not allow client from a.b.c.d to connect to volume brick
- option auth.addr.brick.reject !w.x.y.z #allow client from w.x.y.z to connect to volume brick
- * wildcard '*' can be used to match any ip-address/unix-path
-

-Introduction
-============
-* booster is a LD_PRELOADable library which boosts read/write performance by bypassing fuse for
- read() and write() calls.
-
-Requirements
-============
-* fetch volfile from glusterfs.
-* identify whether multiple files are from the same mount point. If so, use only one context.
-
-Design
-======
-* for a getxattr, along with other attributes, fuse returns following attributes.
- * contents of client volume-file.
- * mount point.
-
-* LD_PRELOADed booster.so maintains an hash table storing mount-points and libglusterfsclient handles
- so that handles are reused for files from same mount point.
-
-* it also maintains a fdtable. fdtable maps the fd (integer) returned to application to fd (pointer to fd struct)
- used by libglusterfsclient. application is returned the same fd as the one returned from libc apis.
-
-* During fork, these tables are overwritten to enable creation of fresh glusterfs context in child.
-
-Working
-=======
-* application willing to use booster LD_PRELOADs booster.so which is a wrapper library implementing
- open, read and write.
-
-* application should specify the path to logfile through the environment variable GLFS_BOOSTER_LOGFILE. If
- not specified, logging is done to /dev/stderr.
-
-* open call does,
- * real_open on the file.
- * fgetxattr(fd).
- * store the volume-file content got in the dictionary to a temparory file.
- * look in the hashtable for the mount-point, if already present get the libglusterfsclient handle from the
- hashtable. Otherwise get a new handle from libglusterfsclient (be careful about mount point not present in
- the hashtable and multiple glusterfs_inits running simultaneously for the same mount-point there by using
- multiple handles for the same mount point).
- * real_close (fd).
- * delete temporary volume-volfile.
- * glusterfs_open (handle, path, mode).
- * store the fd returned by glusterfs_open in the fdtable at the same index as the fd returned by real_open.
- * return the index as fd.
-
-* read/write calls do,
- * get the libglusterfsclient fd from fdtable.
- * if found use glusterfs_read/glusterfs_write, else use real_read/real_write.
-
-* close call does,
- * remove the fd from the fdtable.
-
-* other calls use real_calls.

-\section*{$\bullet$ Structure definitions should have a comment per member}
-
-Every member in a structure definition must have a comment about its
-purpose. The comment should be descriptive without being overly verbose.
-
-\vspace{2ex}
-\textsl{Bad}:
-
-\begin{verbatim}
- gf_lock_t lock; /* lock */
-\end{verbatim}
-
-\textsl{Good}:
-
-\begin{verbatim}
- DBTYPE access_mode; /* access mode for accessing
- * the databases, can be
- * DB_HASH, DB_BTREE
- * (option access-mode <mode>)
- */
-\end{verbatim}
-
-\section*{$\bullet$ Declare all variables at the beginning of the function}
-All local variables in a function must be declared immediately after the
-opening brace. This makes it easy to keep track of memory that needs to be freed
-during exit. It also helps debugging, since gdb cannot handle variables
-declared inside loops or other such blocks.
-
-\section*{$\bullet$ Always initialize local variables}
-Every local variable should be initialized to a sensible default value
-at the point of its declaration. All pointers should be initialized to NULL,
-and all integers should be zero or (if it makes sense) an error value.
-
-\vspace{2ex}
-
-\textsl{Good}:
-
-\begin{verbatim}
- int ret = 0;
- char *databuf = NULL;
- int _fd = -1;
-\end{verbatim}
-
-\section*{$\bullet$ Initialization should always be done with a constant value}
-Never use a non-constant expression as the initialization value for a variable.
-
-\vspace{2ex}
-
-\textsl{Bad}:
-
-\begin{verbatim}
- pid_t pid = frame->root->pid;
- char *databuf = malloc (1024);
-\end{verbatim}
-
-\section*{$\bullet$ Validate all arguments to a function}
-All pointer arguments to a function must be checked for \texttt{NULL}.
-A macro named \texttt{VALIDATE} (in \texttt{common-utils.h})
-takes one argument, and if it is \texttt{NULL}, writes a log message and
-jumps to a label called \texttt{err} after setting op\_ret and op\_errno
-appropriately. It is recommended to use this template.
-
-\vspace{2ex}
-
-\textsl{Good}:
-
-\begin{verbatim}
- VALIDATE(frame);
- VALIDATE(this);
- VALIDATE(inode);
-\end{verbatim}
-
-\section*{$\bullet$ Never rely on precedence of operators}
-Never write code that relies on the precedence of operators to execute
-correctly. Such code can be hard to read and someone else might not
-know the precedence of operators as accurately as you do.
-\vspace{2ex}
-
-\textsl{Bad}:
-
-\begin{verbatim}
- if (op_ret == -1 && errno != ENOENT)
-\end{verbatim}
-
-\textsl{Good}:
-
-\begin{verbatim}
- if ((op_ret == -1) && (errno != ENOENT))
-\end{verbatim}
-
-\section*{$\bullet$ Use exactly matching types}
-Use a variable of the exact type declared in the manual to hold the
-return value of a function. Do not use an ``equivalent'' type.
-
-\vspace{2ex}
-
-\textsl{Bad}:
-
-\begin{verbatim}
- int len = strlen (path);
-\end{verbatim}
-
-\textsl{Good}:
-
-\begin{verbatim}
- size_t len = strlen (path);
-\end{verbatim}
-
-\section*{$\bullet$ Never write code such as \texttt{foo->bar->baz}; check every pointer}
-Do not write code that blindly follows a chain of pointer
-references. Any pointer in the chain may be \texttt{NULL} and thus
-cause a crash. Verify that each pointer is non-null before following
-it.
-
-\section*{$\bullet$ Check return value of all functions and system calls}
-The return value of all system calls and API functions must be checked
-for success or failure.
-
-\vspace{2ex}
-\textsl{Bad}:
-
-\begin{verbatim}
- close (fd);
-\end{verbatim}
-
-\textsl{Good}:
-
-\begin{verbatim}
- op_ret = close (_fd);
- if (op_ret == -1) {
- gf_log (this->name, GF_LOG_ERROR,
- "close on file %s failed (%s)", real_path,
- strerror (errno));
- op_errno = errno;
- goto out;
- }
-\end{verbatim}
-
-
-\section*{$\bullet$ Gracefully handle failure of malloc}
-GlusterFS should never crash or exit due to lack of memory. If a
-memory allocation fails, the call should be unwound and an error
-returned to the user.
-
-\section*{$\bullet$ Use result args and reserve the return value to indicate success or failure}
-The return value of every functions must indicate success or failure (unless
-it is impossible for the function to fail --- e.g., boolean functions). If
-the function needs to return additional data, it must be returned using a
-result (pointer) argument.
-
-\vspace{2ex}
-\textsl{Bad}:
-
-\begin{verbatim}
- int32_t dict_get_int32 (dict_t *this, char *key);
-\end{verbatim}
-
-\textsl{Good}:
-
-\begin{verbatim}
- int dict_get_int32 (dict_t *this, char *key, int32_t *val);
-\end{verbatim}
-
-\section*{$\bullet$ Always use the `n' versions of string functions}
-Unless impossible, use the length-limited versions of the string functions.
-
-\vspace{2ex}
-\textsl{Bad}:
-
-\begin{verbatim}
- strcpy (entry_path, real_path);
-\end{verbatim}
-
-\textsl{Good}:
-
-\begin{verbatim}
- strncpy (entry_path, real_path, entry_path_len);
-\end{verbatim}
-
-\section*{$\bullet$ No dead or commented code}
-There must be no dead code (code to which control can never be passed) or
-commented out code in the codebase.
-
-\section*{$\bullet$ Only one unwind and return per function}
-There must be only one exit out of a function. \texttt{UNWIND} and return
-should happen at only point in the function.
-
-\section*{$\bullet$ Function length or Keep functions small}
-We live in the UNIX-world where modules do one thing and do it well.
-This rule should apply to our functions also. If a function is very long, try splitting it
-into many little helper functions. The question is, in a coding
-spree, how do we know a function is long and unreadable. One rule of
-thumb given by Linus Torvalds is that, a function should be broken-up
-if you have 4 or more levels of indentation going on for more than 3-4
-lines.
-
-\vspace{2ex}
-\textsl{Example for a helper function}:
-\begin{verbatim}
- static int
- same_owner (posix_lock_t *l1, posix_lock_t *l2)
- {
- return ((l1->client_pid == l2->client_pid) &&
- (l1->transport == l2->transport));
- }
-\end{verbatim}
-
-\section*{$\bullet$ Defining functions as static}
-Define internal functions as static only if you're
-very sure that there will not be a crash(..of any kind..) emanating in
-that function. If there is even a remote possibility, perhaps due to
-pointer derefering, etc, declare the function as non-static. This
-ensures that when a crash does happen, the function name shows up the
-in the back-trace generated by libc. However, doing so has potential
-for polluting the function namespace, so to avoid conflicts with other
-components in other parts, ensure that the function names are
-prepended with a prefix that identify the component to which it
-belongs. For eg. non-static functions in io-threads translator start
-with iot\_.
-
-\section*{$\bullet$ Ensure function calls wrap around after
-80-columns.}
-Place remaining arguments on the next line if needed.
-
-\section*{$\bullet$ Functions arguments and function definition}
-Place all the arguments of a function definition on the same line
-until the line goes beyond 80-cols. Arguments that extend beyind
-80-cols should be placed on the next line.
-
-\section*{Style issues}
-
-\subsection*{Brace placement}
-Use K\&R/Linux style of brace placement for blocks.
-
-\textsl{Example}:
-\begin{verbatim}
- int some_function (...)

-\subsection*{Indentation}
-Use \textbf{eight} spaces for indenting blocks. Ensure that your
-file contains only spaces and not tab characters. You can do this
-in Emacs by selecting the entire file (\texttt{C-x h}) and
-running \texttt{M-x untabify}.
-
-To make Emacs indent lines automatically by eight spaces, add this
-line to your \texttt{.emacs}:
-
-\begin{verbatim}
- (add-hook 'c-mode-hook (lambda () (c-set-style "linux")))
-\end{verbatim}
-
-\subsection*{Comments}
-Write a comment before every function describing its purpose (one-line),
-its arguments, and its return value. Mention whether it is an internal
-function or an exported function.
-
-Write a comment before every structure describing its purpose, and
-write comments about each of its members.
-
-Follow the style shown below for comments, since such comments
-can then be automatically extracted by doxygen to generate
-documentation.
-
-\textsl{Example}:
-\begin{verbatim}
-/**
- * hash_name -hash function for filenames
- * @par: parent inode number
- * @name: basename of inode
- * @mod: number of buckets in the hashtable
- *
- * @return: success: bucket number
- * failure: -1
- *
- * Not for external use.
- */
-\end{verbatim}
-
-\subsection*{Indicating critical sections}
-To clearly show regions of code which execute with locks held, use
-the following format:
-
-\begin{verbatim}
- pthread_mutex_lock (&mutex);
- {
- /* code */
- }
- pthread_mutex_unlock (&mutex);
-\end{verbatim}
-
-\section*{A skeleton fop function}
-This is the recommended template for any fop. In the beginning come
-the initializations. After that, the `success' control flow should be
-linear. Any error conditions should cause a \texttt{goto} to a single
-point, \texttt{out}. At that point, the code should detect the error
-that has occured and do appropriate cleanup.
-
-\begin{verbatim}
-int32_t
-sample_fop (call_frame_t *frame, xlator_t *this, ...)
-{
- char * var1 = NULL;
- int32_t op_ret = -1;

+# Analyzing Regression Cores
+This document explains how to analyze core-dumps obtained from regression machines, with examples.
+1. Download the core-tarball and extract it.
+2. `cd` into directory where the tarball is extracted.
+```
+[sh]# pwd
+/home/user/Downloads
+[sh]# ls
+build build-install-20150625_05_42_39.tar.bz2 lib64 usr
+```
+3. Determine the core file you need to examine. There can be more than one core file. You can list them from './build/install/cores' directory.
+```
+[sh]# ls build/install/cores/
+core.9341 liblist.txt liblist.txt.tmp
+```
+In case you are unsure which binary generated the core-file, executing 'file' command on it will help.
+```
+[sh]# file ./build/install/cores/core.9341
+./build/install/cores/core.9341: ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style, from '/build/install/sbin/glusterfsd -s slave26.cloud.gluster.org --volfile-id patchy'
+```
+As seen, the core file was generated by glusterfsd binary, and path to it is provided (/build/install/sbin/glusterfsd).
+
+4. Now, run the following command on the core:
+```
+gdb -ex 'set sysroot ./' -ex 'core-file ./build/install/cores/core.xxx' <target, say ./build/install/sbin/glusterd>
+In this case,
+gdb -ex 'set sysroot ./' -ex 'core-file ./build/install/cores/core.9341' ./build/install/sbin/glusterfsd
+```
+5. You can cross check if all shared libraries are available and loaded by using 'info sharedlibrary' command from inside gdb.
+6. Once verified, usual gdb commands based on requirement can be used to debug the core.
+ `bt` or `backtrace` from gdb of core used in examples:
+```
+Core was generated by `/build/install/sbin/glusterfsd -s slave26.cloud.gluster.org --volfile-id patchy'.

+# Convert GFID to Path
+
+GlusterFS internal file identifier (GFID) is a uuid that is unique to each
+file across the entire cluster. This is analogous to inode number in a
+normal filesystem. The GFID of a file is stored in its xattr named
+`trusted.gfid`.
+
+#### Special mount using [gfid-access translator][1]:
+```
+mount -t glusterfs -o aux-gfid-mount vm1:test /mnt/testvol
+```
+
+Assuming, you have `GFID` of a file from changelog (or somewhere else).
+For trying this out, you can get `GFID` of a file from mountpoint:
+```
+getfattr -n glusterfs.gfid.string /mnt/testvol/dir/file
+```
+
+
+---
+### Get file path from GFID (Method 1):
+**(Lists hardlinks delimited by `:`, returns path as seen from mountpoint)**
+
+#### Turn on build-pgfid option
+```
+gluster volume set test build-pgfid on
+```
+Read virtual xattr `glusterfs.ancestry.path` which contains the file path
+```
+getfattr -n glusterfs.ancestry.path -e text /mnt/testvol/.gfid/<GFID>
+```
+
+**Example:**
+```
+[root@vm1 glusterfs]# ls -il /mnt/testvol/dir/
+total 1
+10610563327990022372 -rw-r--r--. 2 root root 3 Jul 17 18:05 file

+glusterfs.ancestry.path="/dir/file:/dir/file3"
+```
+
+---
+### Get file path from GFID (Method 2):
+**(Does not list all hardlinks, returns backend brick path)**
+```
+getfattr -n trusted.glusterfs.pathinfo -e text /mnt/testvol/.gfid/<GFID>
+```
+
+**Example:**
+```
+[root@vm1 glusterfs]# getfattr -n trusted.glusterfs.pathinfo -e text /mnt/testvol/.gfid/11118443-1894-4273-9340-4b212fa1c0e4

+# file: mnt/testvol/.gfid/11118443-1894-4273-9340-4b212fa1c0e4
+trusted.glusterfs.pathinfo="(<DISTRIBUTE:test-dht> <POSIX(/mnt/brick-test/b):vm1:/mnt/brick-test/b/dir//file3>)"

+## Viewing Memory Allocations
+
+While statedumps provide stats of the number of allocations, size etc for a
+particular mem type, there is no easy way to examine all the allocated objects of that type
+in memory.Being able to view this information could help with determining how an object is used,
+and if there are any memory leaks.
+
+The mem_acct_rec structures have been updated to include lists to which the allocated object is
+added. These can be examined in gdb using simple scripts.
+
+`gdb> plist xl->mem_acct.rec[$type]->obj_list`
+
+will print out the pointers of all allocations of $type.
+
+These changes are primarily targeted at developers and need to enabled
+at compile-time using `configure --enable-debug`.

+# Steps to recover from File split-brain
+This document contains steps to recover from a file split-brain.
+## Quick Start:
+### Step 1. Get the path of the file that is in split-brain:
+It can be obtained either by
+1. The command `gluster volume heal info split-brain`.
+2. Identify the files for which file operations performed from the client keep failing with Input/Output error.
+
+### Step 2. Close the applications that opened this file from the mount point.
+In case of VMs, they need to be powered-off.
+
+### Step 3. Decide on the correct copy:
+This is done by observing the afr changelog extended attributes of the file on
+the bricks using the getfattr command; then identifying the type of split-brain
+(data split-brain, metadata split-brain, entry split-brain or split-brain due to
+gfid-mismatch); and finally determining which of the bricks contains the 'good copy'
+of the file.
+```
+getfattr -d -m . -e hex <file-path-on-brick>
+```
+
+It is also possible that one brick might contain the correct data while the
+other might contain the correct metadata.
+
+### Step 4. Reset the relevant extended attribute on the brick(s) that contains the 'bad copy' of the file data/metadata using the setfattr command.
+```
+setfattr -n <attribute-name> -v <attribute-value> <file-path-on-brick>
+```
+
+### Step 5. Trigger self-heal on the file by performing lookup from the client:
+```
+ls -l <file-path-on-gluster-mount>
+```
+
+Detailed Instructions for steps 3 through 5:
+===========================================
+To understand how to resolve split-brain we need to know how to interpret the
+afr changelog extended attributes.
+
+Execute `getfattr -d -m . -e hex <file-path-on-brick>`
+
+Example:
+```
+[root@store3 ~]# getfattr -d -e hex -m. brick-a/file.txt
+\#file: brick-a/file.txt
+security.selinux=0x726f6f743a6f626a6563745f723a66696c655f743a733000
+trusted.afr.vol-client-2=0x000000000000000000000000
+trusted.afr.vol-client-3=0x000000000200000000000000
+trusted.gfid=0x307a5c9efddd4e7c96e94fd4bcdcbd1b
+```
+
+The extended attributes with `trusted.afr.<volname>-client-<subvolume-index>`
+are used by afr to maintain changelog of the file.The values of the
+`trusted.afr.<volname>-client-<subvolume-index>` are calculated by the glusterfs
+client (fuse or nfs-server) processes. When the glusterfs client modifies a file
+or directory, the client contacts each brick and updates the changelog extended
+attribute according to the response of the brick.
+
+`subvolume-index` is nothing but (brick number - 1) in
+`gluster volume info <volname>` output.
+
+Example:
+```
+[root@pranithk-laptop ~]# gluster volume info vol
+ Volume Name: vol
+ Type: Distributed-Replicate
+ Volume ID: 4f2d7849-fbd6-40a2-b346-d13420978a01
+ Status: Created
+ Number of Bricks: 4 x 2 = 8
+ Transport-type: tcp
+ Bricks:
+ brick-a: pranithk-laptop:/gfs/brick-a
+ brick-b: pranithk-laptop:/gfs/brick-b
+ brick-c: pranithk-laptop:/gfs/brick-c
+ brick-d: pranithk-laptop:/gfs/brick-d
+ brick-e: pranithk-laptop:/gfs/brick-e
+ brick-f: pranithk-laptop:/gfs/brick-f
+ brick-g: pranithk-laptop:/gfs/brick-g
+ brick-h: pranithk-laptop:/gfs/brick-h
+```
+
+In the example above:
+```
+Brick | Replica set | Brick subvolume index
+----------------------------------------------------------------------------
+-/gfs/brick-a | 0 | 0
+-/gfs/brick-b | 0 | 1
+-/gfs/brick-c | 1 | 2
+-/gfs/brick-d | 1 | 3
+-/gfs/brick-e | 2 | 4
+-/gfs/brick-f | 2 | 5
+-/gfs/brick-g | 3 | 6
+-/gfs/brick-h | 3 | 7
+```
+
+Each file in a brick maintains the changelog of itself and that of the files
+present in all the other bricks in it's replica set as seen by that brick.
+
+In the example volume given above, all files in brick-a will have 2 entries,
+one for itself and the other for the file present in it's replica pair, i.e.brick-b:
+```
+trusted.afr.vol-client-0=0x000000000000000000000000 -->changelog for itself (brick-a)
+trusted.afr.vol-client-1=0x000000000000000000000000 -->changelog for brick-b as seen by brick-a
+```
+Likewise, all files in brick-b will have:
+```
+trusted.afr.vol-client-0=0x000000000000000000000000 -->changelog for brick-a as seen by brick-b
+trusted.afr.vol-client-1=0x000000000000000000000000 -->changelog for itself (brick-b)
+```
+
+The same can be extended for other replica pairs.
+
+Interpreting Changelog (roughly pending operation count) Value:
+Each extended attribute has a value which is 24 hexa decimal digits.
+First 8 digits represent changelog of data. Second 8 digits represent changelog
+of metadata. Last 8 digits represent Changelog of directory entries.
+
+Pictorially representing the same, we have:
+```
+0x 000003d7 00000001 00000000
+ | | |
+ | | \_ changelog of directory entries
+ | \_ changelog of metadata
+ \ _ changelog of data
+```
+
+
+For Directories metadata and entry changelogs are valid.
+For regular files data and metadata changelogs are valid.
+For special files like device files etc metadata changelog is valid.
+When a file split-brain happens it could be either data split-brain or
+meta-data split-brain or both. When a split-brain happens the changelog of the
+file would be something like this:
+
+Example:(Lets consider both data, metadata split-brain on same file).
+```
+[root@pranithk-laptop vol]# getfattr -d -m . -e hex /gfs/brick-?/a
+getfattr: Removing leading '/' from absolute path names
+\#file: gfs/brick-a/a
+trusted.afr.vol-client-0=0x000000000000000000000000
+trusted.afr.vol-client-1=0x000003d70000000100000000
+trusted.gfid=0x80acdbd886524f6fbefa21fc356fed57
+\#file: gfs/brick-b/a
+trusted.afr.vol-client-0=0x000003b00000000100000000
+trusted.afr.vol-client-1=0x000000000000000000000000
+trusted.gfid=0x80acdbd886524f6fbefa21fc356fed57
+```
+
+### Observations:
+
+#### According to changelog extended attributes on file /gfs/brick-a/a:
+The first 8 digits of trusted.afr.vol-client-0 are all
+zeros (0x00000000................), and the first 8 digits of
+trusted.afr.vol-client-1 are not all zeros (0x000003d7................).
+So the changelog on /gfs/brick-a/a implies that some data operations succeeded
+on itself but failed on /gfs/brick-b/a.
+
+The second 8 digits of trusted.afr.vol-client-0 are
+all zeros (0x........00000000........), and the second 8 digits of
+trusted.afr.vol-client-1 are not all zeros (0x........00000001........).
+So the changelog on /gfs/brick-a/a implies that some metadata operations succeeded
+on itself but failed on /gfs/brick-b/a.
+
+#### According to Changelog extended attributes on file /gfs/brick-b/a:
+The first 8 digits of trusted.afr.vol-client-0 are not all
+zeros (0x000003b0................), and the first 8 digits of
+trusted.afr.vol-client-1 are all zeros (0x00000000................).
+So the changelog on /gfs/brick-b/a implies that some data operations succeeded
+on itself but failed on /gfs/brick-a/a.
+
+The second 8 digits of trusted.afr.vol-client-0 are not
+all zeros (0x........00000001........), and the second 8 digits of
+trusted.afr.vol-client-1 are all zeros (0x........00000000........).
+So the changelog on /gfs/brick-b/a implies that some metadata operations succeeded
+on itself but failed on /gfs/brick-a/a.
+
+Since both the copies have data, metadata changes that are not on the other
+file, it is in both data and metadata split-brain.
+
+Deciding on the correct copy:
+-----------------------------
+The user may have to inspect stat,getfattr output of the files to decide which
+metadata to retain and contents of the file to decide which data to retain.
+Continuing with the example above, lets say we want to retain the data
+of /gfs/brick-a/a and metadata of /gfs/brick-b/a.
+
+Resetting the relevant changelogs to resolve the split-brain:
+-------------------------------------------------------------
+For resolving data-split-brain:
+We need to change the changelog extended attributes on the files as if some data
+operations succeeded on /gfs/brick-a/a but failed on /gfs/brick-b/a. But
+/gfs/brick-b/a should NOT have any changelog which says some data operations
+succeeded on /gfs/brick-b/a but failed on /gfs/brick-a/a. We need to reset the
+data part of the changelog on trusted.afr.vol-client-0 of /gfs/brick-b/a.
+
+For resolving metadata-split-brain:
+We need to change the changelog extended attributes on the files as if some
+metadata operations succeeded on /gfs/brick-b/a but failed on /gfs/brick-a/a.
+But /gfs/brick-a/a should NOT have any changelog which says some metadata
+operations succeeded on /gfs/brick-a/a but failed on /gfs/brick-b/a.
+We need to reset metadata part of the changelog on
+trusted.afr.vol-client-1 of /gfs/brick-a/a
+
+So, the intended changes are:
+On /gfs/brick-b/a:
+For trusted.afr.vol-client-0
+0x000003b00000000100000000 to 0x000000000000000100000000
+(Note that the metadata part is still not all zeros)
+Hence execute
+`setfattr -n trusted.afr.vol-client-0 -v 0x000000000000000100000000 /gfs/brick-b/a`
+
+On /gfs/brick-a/a:
+For trusted.afr.vol-client-1
+0x0000000000000000ffffffff to 0x000003d70000000000000000
+(Note that the data part is still not all zeros)
+Hence execute
+`setfattr -n trusted.afr.vol-client-1 -v 0x000003d70000000000000000 /gfs/brick-a/a`
+
+Thus after the above operations are done, the changelogs look like this:
+```

+
+Triggering Self-heal:
+---------------------
+Perform `ls -l <file-path-on-gluster-mount>` to trigger healing.
+
+Fixing Directory entry split-brain:
+----------------------------------
+Afr has the ability to conservatively merge different entries in the directories
+when there is a split-brain on directory.
+If on one brick directory 'd' has entries '1', '2' and has entries '3', '4' on
+the other brick then afr will merge all of the entries in the directory to have
+'1', '2', '3', '4' entries in the same directory.
+(Note: this may result in deleted files to re-appear in case the split-brain
+happens because of deletion of files on the directory)
+Split-brain resolution needs human intervention when there is at least one entry
+which has same file name but different gfid in that directory.
+Example:
+On brick-a the directory has entries '1' (with gfid g1), '2' and on brick-b
+directory has entries '1' (with gfid g2) and '3'.
+These kinds of directory split-brains need human intervention to resolve.
+The user needs to remove either file '1' on brick-a or the file '1' on brick-b
+to resolve the split-brain. In addition, the corresponding gfid-link file also
+needs to be removed.The gfid-link files are present in the .glusterfs folder
+in the top-level directory of the brick. If the gfid of the file is
+0x307a5c9efddd4e7c96e94fd4bcdcbd1b (the trusted.gfid extended attribute got
+from the getfattr command earlier),the gfid-link file can be found at
+`/gfs/brick-a/.glusterfs/30/7a/307a5c9efddd4e7c96e94fd4bcdcbd1b`
+
+#### Word of caution:
+Before deleting the gfid-link, we have to ensure that there are no hard links
+to the file present on that brick. If hard-links exist,they must be deleted as
+well.

+# Statedump
+Statedump is a file generated by glusterfs process with different data structure state which may contain the active inodes, fds, mempools, iobufs, memory allocation stats of different types of datastructures per xlator etc.
+
+## How to generate statedump
+We can find the directory where statedump files are created using `gluster --print-statedumpdir` command.
+Create that directory if not already present based on the type of installation.
+Lets call this directory `statedump-directory`.
+
+We can generate statedump using `kill -USR1 <pid-of-gluster-process>`.
+gluster-process is nothing but glusterd/glusterfs/glusterfsd process.
+
+There are also commands to generate statedumps for brick processes/nfs server/quotad
+
+For bricks:
+```
+gluster volume statedump <volname>
+```
+
+For nfs server:
+```
+gluster volume statedump <volname> nfs
+```
+
+For quotad:
+```
+gluster volume statedump <volname> quotad
+```
+
+For brick-processes files will be created in `statedump-directory` with name of the file as `hyphenated-brick-path.<pid>.dump.timestamp`. For all other processes it will be `glusterdump.<pid>.dump.timestamp`.
+
+For applications using libgfapi, `SIGUSR1` cannot be used, eg: smbd/libvirtd
+processes could have used the `SIGUSR1` signal already for other purposes.
+To generate statedump for the processes, using libgfapi, below command can be
+executed from one of the nodes in the gluster cluster to which the libgfapi
+application is connected to.
+```
+gluster volume statedump <volname> client <hostname>:<process id>
+```
+The statedumps can be found in the `statedump-directory`, the name of the
+statedumps being `glusterdump.<pid>.dump.timestamp`. For a process there can be
+multiple such files created depending on the number of times the volume is
+accessed by the process (related to the number of `glfs_init()` calls).
+
+## How to read statedump
+We shall see snippets of each type of statedump.
+
+First and last lines of the file have starting and ending time of writing the statedump file. Times will be in UTC timezone.
+
+mallinfo return status is printed in the following format. Please read man mallinfo for more information about what each field means.
+### Mallinfo
+```
+[mallinfo]
+mallinfo_arena=100020224 /* Non-mmapped space allocated (bytes) */
+mallinfo_ordblks=69467 /* Number of free chunks */
+mallinfo_smblks=449 /* Number of free fastbin blocks */
+mallinfo_hblks=13 /* Number of mmapped regions */

+mallinfo_fordblks=3310112 /* Total free space (bytes) */
+mallinfo_keepcost=133712 /* Top-most, releasable space (bytes) */
+```
+
+### Data structure allocation stats
+For every xlator data structure memory per translator loaded in the call-graph is displayed in the following format:
+
+For xlator with name: glusterfs
+```
+[global.glusterfs - Memory usage] #[global.xlator-name - Memory usage]
+num_types=119 #It shows the number of data types it is using
+```
+
+Now for each data-type it prints the memory usage.
+
+```
+[global.glusterfs - usage-type gf_common_mt_gf_timer_t memusage]
+#[global.xlator-name - usage-type <tag associated with the data-type> memusage]
+size=112 #num_allocs times the sizeof(data-type) i.e. num_allocs * sizeof (data-type)
+num_allocs=2 #Number of allocations of the data-type which are active at the time of taking statedump.
+max_size=168 #max_num_allocs times the sizeof(data-type) i.e. max_num_allocs * sizeof (data-type)
+max_num_allocs=3 #Maximum number of active allocations at any point in the life of the process.
+total_allocs=7 #Number of times this data is allocated in the life of the process.
+```
+
+### Mempools
+
+Mempools are optimization to reduce the number of allocations of a data type. If we create a mem-pool of lets say 1024 elements for a data-type, new elements will be allocated from heap using syscalls like calloc, only if all the 1024 elements in the pool are in active use.
+
+Memory pool allocated by each xlator is displayed in the following format:
+
+```
+[mempool] #Section name
+-----=-----
+pool-name=fuse:fd_t #pool-name=<xlator-name>:<data-type>
+hot-count=1 #number of mempool elements that are in active use. i.e. for this pool it is the number of 'fd_t' s in active use.
+cold-count=1023 #number of mempool elements that are not in use. If a new allocation is required it will be served from here until all the elements in the pool are in use i.e. cold-count becomes 0.
+padded_sizeof=108 #Each mempool element is padded with a doubly-linked-list + ptr of mempool + is-in-use info to operate the pool of elements, this size is the element-size after padding
+pool-misses=0 #Number of times the element had to be allocated from heap because all elements from the pool are in active use.
+alloc-count=314 #Number of times this type of data is allocated through out the life of this process. This may include pool-misses as well.
+max-alloc=3 #Maximum number of elements from the pool in active use at any point in the life of the process. This does *not* include pool-misses.
+cur-stdalloc=0 #Denotes the number of allocations made from heap once cold-count reaches 0, that are yet to be released via mem_put().
+max-stdalloc=0 #Maximum number of allocations from heap that are in active use at any point in the life of the process.
+```
+
+### Iobufs
+```
+[iobuf.global]
+iobuf_pool=0x1f0d970 #The memory pool for iobufs
+iobuf_pool.default_page_size=131072 #The default size of iobuf (if no iobuf size is specified the default size is allocated)
+#iobuf_arena: One arena represents a group of iobufs of a particular size
+iobuf_pool.arena_size=12976128 # The initial size of the iobuf pool (doesn't include the stdalloc'd memory or the newly added arenas)
+iobuf_pool.arena_cnt=8 #Total number of arenas in the pool
+iobuf_pool.request_misses=0 #The number of iobufs that were stdalloc'd (as they exceeded the default max page size provided by iobuf_pool).
+```
+
+There are 3 lists of arenas:
+
+1. Arena list: arenas allocated during iobuf pool creation and the arenas that are in use(active_cnt != 0) will be part of this list.
+2. Purge list: arenas that can be purged(no active iobufs, active_cnt == 0).
+3. Filled list: arenas without free iobufs.
+
+```
+[purge.1] #purge.<S.No.>
+purge.1.mem_base=0x7fc47b35f000 #The address of the arena structure
+purge.1.active_cnt=0 #The number of iobufs active in that arena
+purge.1.passive_cnt=1024 #The number of unused iobufs in the arena
+purge.1.alloc_cnt=22853 #Total allocs in this pool(number of times the iobuf was allocated from this arena)
+purge.1.max_active=7 #Max active iobufs from this arena, at any point in the life of this process.
+purge.1.page_size=128 #Size of all the iobufs in this arena.
+
+[arena.5] #arena.<S.No.>
+arena.5.mem_base=0x7fc47af1f000
+arena.5.active_cnt=0
+arena.5.passive_cnt=64
+arena.5.alloc_cnt=0
+arena.5.max_active=0
+arena.5.page_size=32768
+```
+
+If the active_cnt of any arena is non zero, then the statedump will also have the iobuf list.
+```
+[arena.6.active_iobuf.1] #arena.<S.No>.active_iobuf.<iobuf.S.No.>
+arena.6.active_iobuf.1.ref=1 #refcount of the iobuf
+arena.6.active_iobuf.1.ptr=0x7fdb921a9000 #address of the iobuf
+
+[arena.6.active_iobuf.2]
+arena.6.active_iobuf.2.ref=1
+arena.6.active_iobuf.2.ptr=0x7fdb92189000
+```
+
+At any given point in time if there are lots of filled arenas then that could be a sign of iobuf leaks.
+
+### Call stack
+All the fops received by gluster are handled using call-stacks. Call stack contains the information about uid/gid/pid etc of the process that is executing the fop. Each call-stack contains different call-frames per xlator which handles that fop.
+
+```
+[global.callpool.stack.3] #global.callpool.stack.<Serial-Number>
+stack=0x7fc47a44bbe0 #Stack address
+uid=0 #Uid of the process which is executing the fop
+gid=0 #Gid of the process which is executing the fop
+pid=6223 #Pid of the process which is executing the fop
+unique=2778 #Xlators like afr do copy_frame and perform the operation in a different stack, this id is useful to find out the stacks that are inter-related because of copy-frame
+lk-owner=0000000000000000 #Some of the fuse fops have lk-owner.
+op=LOOKUP #Fop
+type=1 #Type of the op i.e. FOP/MGMT-OP
+cnt=9 #Number of frames in this stack.
+```
+### Call-frame
+Each frame will have information about which xlator the frame belongs to, what is the function it wound to/from and will be unwind to. It also mentions if the unwind happened or not. If we observe hangs in the system and want to find out which xlator is causing it. Take a statedump and see what is the final xlator which is yet to be unwound.
+
+```
+[global.callpool.stack.3.frame.2]#global.callpool.stack.<stack-serial-number>.frame.<frame-serial-number>
+frame=0x7fc47a611dbc #Frame address
+ref_count=0 #Incremented at the time of wind and decremented at the time of unwind.
+translator=r2-client-1 #Xlator this frame belongs to
+complete=0 #if this value is 1 that means this frame is already unwound. 0 if it is yet to unwind.
+parent=r2-replicate-0 #Parent xlator of this frame
+wind_from=afr_lookup #Parent xlator function from which the wind happened
+wind_to=priv->children[i]->fops->lookup
+unwind_to=afr_lookup_cbk #Parent xlator function to which unwind happened
+```

+## FAQ
+### How to debug Memory leaks using statedump?
+
+#### Using memory accounting feature:
+
+[Bug 1120151](https://bugzilla.redhat.com/show_bug.cgi?id=1120151) is one of the bugs which was debugged using statedump to see which data-structure is leaking. Here is the process used to find what the leak is using statedump. According to the bug the observation is that the process memory usage is increasing whenever one of the bricks is wiped in a replicate volume and a `full` self-heal is invoked to heal the contents. Statedump of the process is taken using `kill -USR1 <pid-of-gluster-self-heal-daemon>`.
+```
+grep -w num_allocs glusterdump.5225.dump.1405493251
+num_allocs=77078
+num_allocs=87070
+num_allocs=117376
+....
+
+grep hot-count glusterdump.5225.dump.1405493251
+hot-count=16384
+hot-count=16384
+hot-count=4095
+....
+
+Find the occurrences in the statedump file to figure out the tags.
+```
+grep of the statedump revealed too many allocations for the following data-types under replicate,
+
+1. gf_common_mt_asprintf
+2. gf_common_mt_char
+3. gf_common_mt_mem_pool.
+
+After checking afr-code for allocations with tag `gf_common_mt_char` found `data-self-heal` code path does not free one such allocated memory. `gf_common_mt_mem_pool` suggests that there is a leak in pool memory. `replicate-0:dict_t`, `glusterfs:data_t` and `glusterfs:data_pair_t` pools are using lot of memory, i.e. cold_count is `0` and too many allocations. Checking source code of dict.c revealed that `key` in `dict` is allocated with `gf_common_mt_char` i.e. `2.` tag and value is created using gf_asprintf which in-turn uses `gf_common_mt_asprintf` i.e. `1.`. Browsing the code for leak in self-heal code paths lead to a line which over-writes a variable with new dictionary even when it was already holding a reference to another dictionary. After fixing these leaks, ran the same test to verify that none of the `num_allocs` are increasing even after healing 10,000 files directory hierarchy in statedump of self-heal daemon.
+Please check this [patch](http://review.gluster.org/8316) for more info about the fix.
+
+#### Debugging leaks in memory pools:
+Statedump output of memory pools was used to test and verify the fixes to [Bug 1134221](https://bugzilla.redhat.com/show_bug.cgi?id=1134221). On code analysis, dict_t objects were found to be leaking (in terms of not being unref'd enough number of times, during name self-heal. The test involved creating 100 files on plain replicate volume, removing them from one of the brick's backend, and then triggering lookup on them from the mount point. Statedump of the mount process was taken before executing the test case and after it, after compiling glusterfs with -DDEBUG flags (to have cold count set to 0 by default).
+
+Statedump output of the fuse mount process before the test case was executed:
+
+```
+
+pool-name=glusterfs:dict_t
+hot-count=0
+cold-count=0
+padded_sizeof=140
+alloc-count=33
+max-alloc=0
+pool-misses=33
+cur-stdalloc=14
+max-stdalloc=18
+
+```
+Statedump output of the fuse mount process after the test case was executed:
+
+```
+
+pool-name=glusterfs:dict_t
+hot-count=0
+cold-count=0
+padded_sizeof=140
+alloc-count=2841
+max-alloc=0
+pool-misses=2841
+cur-stdalloc=214
+max-stdalloc=220
+
+```
+Here, with cold count being 0 by default, `cur-stdalloc` indicated the number of `dict_t` objects that were allocated in heap using `mem_get()`, and yet to be freed using `mem_put()` (refer to this [page](../developer-guide/datastructure-mem-pool.md) for more details on how mempool works). After the test case (name selfheal of 100 files), there was a rise in the cur-stdalloc value (from 14 to 214) for `dict_t`.
+
+After these leaks were fixed, glusterfs was again compiled with -DDEBUG flags, and the same steps were performed again and statedump was taken before and after executing the test case, of the mount. This was done to ascertain the validity of the fix. And the following are the results:
+
+Statedump output of the fuse mount process before executing the test case:
+
+```
+pool-name=glusterfs:dict_t
+hot-count=0
+cold-count=0
+padded_sizeof=140
+alloc-count=33
+max-alloc=0
+pool-misses=33
+cur-stdalloc=14
+max-stdalloc=18
+
+```
+Statedump output of the fuse mount process after executing the test case:
+
+```
+pool-name=glusterfs:dict_t
+hot-count=0
+cold-count=0
+padded_sizeof=140
+alloc-count=2837
+max-alloc=0
+pool-misses=2837
+cur-stdalloc=14
+max-stdalloc=119
+
+```
+The value of cur-stdalloc remained 14 before and after the test, indicating that the fix indeed does what it's supposed to do.
+
+### How to debug hangs because of frame-loss?
+[Bug 994959](https://bugzilla.redhat.com/show_bug.cgi?id=994959) is one of the bugs where statedump was helpful in finding where the frame was lost. Here is the process used to find where the hang is using statedump.
+When the hang was observed, statedumps are taken for all the processes. On mount's statedump the following stack is shown:

+# USing Gluster Test Framwork
+Description
+-----------
+
+The Gluster Test Framework, is a suite of scripts used for regression
+testing of Gluster.
+
+It runs well on RHEL and CentOS (possibly Fedora too, presently being
+tested), and is automatically run against every patch submitted to
+Gluster [for review](http://review.gluster.org).
+
+The Gluster Test Framework is part of the main Gluster code base, living
+under the "tests" subdirectory:
+
+ http://git.gluster.org/?p=glusterfs.git;a=summary
+
+WARNING
+-------
+
+Running the Gluster Test Framework deletes “/var/lib/glusterd/\*â€.
+
+**DO NOT run it on a server with any data.**

+
+Common steps
+------------
+
+​1. Ensure DNS for your server is working
+
+The Gluster Test Framework fails miserably if the full domain name for
+your server doesn't resolve back to itself.
+
+If you don't have a working DNS infrastructure in place, adding an entry
+for your server to its /etc/hosts file will work.
+
+​2. Install the version of Gluster you are testing
+
+Either install an existing set of rpms:
+
+ $ sudo yum install [your gluster rpms here]
+
+Or compile your own ones (fairly easy):
+
+ http://www.gluster.org/community/documentation/index.php/CompilingRPMS
+
+​3. Clone the GlusterFS git repository
+
+ $ git clone git://git.gluster.org/glusterfs
+ $ cd glusterfs
+
+Ensure mock can access the directory
+------------------------------------
+
+Some tests run as the user "mock". If the mock user can't access the
+tests subdirectory directory, these tests fail. (rpm.t is one such test)
+
+This is a known gotcha when the git repo is cloned to your home
+directory. Home directories generally don't have world readable
+permissions. You can fix this by adjusting your home directory
+permissions, or placing the git repo somewhere else (with access for the
+mock user).
+
+Running the tests
+-----------------
+
+The tests need to run as root, so they can mount volumes and manage
+gluster processes as needed.
+
+It's also best to run them directly as the root user, instead of through
+sudo. Strange things sporadicly happen (for me) when using the full test
+framework through sudo, that haven't happened (yet) when running
+directly as root. Hangs in dbench particularly, which are part of at
+least one test.
+
+ # ./run-tests.sh
+
+The test framework takes just over 45 minutes to run in a VM here (4
+cpu's assigned, 8GB ram, SSD storage). It may take significantly more or
+less time for you, depending on the hardware and software you're using.
+
+Showing debug information
+-------------------------
+
+To display verbose information while the tests are running, set the
+DEBUG environment variable to 1 prior to running the tests.
+
+ # DEBUG=1 ./run-tests.sh
+
+Log files
+---------
+
+Verbose output from the rpm.t test goes into "rpmbuild-mock.log",
+located in the same directory the test is run from.
+
+Reporting bugs
+--------------
+
+If you hit a bug when running the test framework, **please** create a
+bug report for it on Bugzilla so it gets fixed:
+
+ https://bugzilla.redhat.com/enter_bug.cgi?product=GlusterFS&component=tests
+
+Creating your own tests
+-----------------------
+
+The test scripts are written in bash, with their filenames ending in .t
+instead of .sh.
+
+When creating your own test scripts, create them in an appropriate
+subdirectory under "tests" (eg "bugs" or "features") and use descriptive
+names like "bug-XXXXXXX-checking-feature-X.t"
+
+Also include the "include.rc" file, which defines the test types and
+host/brick/volume defaults:
+
+ . $(dirname $0)/../include.rc
+
+There are 5 test types available at present, but feel free to add more
+if you need something that doesn't yet exist. The test types are
+explained in more detail below.
+
+Also essential is the "cleanup" command, which removes any existing
+Gluster configuration (**without backing it up**), and also kills any
+running gluster processes.
+
+There is a basic test template you can copy, named bug-000000.t in the
+bugs subdirectory:
+
+ $ cp bugs/bug-000000.t somedir/descriptive-name.t

+History of locking in AFR
+--------------------------
+
+GlusterFS has **locks** translator which provides the following internal locking operations called `inodelk`, `entrylk` which are used by afr to achieve synchronization of operations on files or directories that conflict with each other.
+
+`Inodelk` gives the facility for translators in GlusterFS to obtain range (denoted by tuple with **offset**, **length**) locks in a given **domain** for an inode.
+Full file lock is denoted by the tuple (offset: `0`, length: `0`) i.e. length `0` is considered as infinity.
+
+`Entrylk` enables translators of GlusterFS to obtain locks on `name` in a given **domain** for an inode, typically a directory.
+
+The **locks** translator provides both *blocking* and *nonblocking* variants and of these locks.
+
+
+AFR makes use of locks xlator extensively:
+
+1)For FOPS (from clients)
+-----------------------
+* Data transactions take inode locks on data domain, Let's refer to this domain name as DATA_DOMAIN.
+
+ So locking for writes would be something like this:`inodelk(offset,length, DATA_DOMAIN)`
+ For truncating a file to zero, it would be `inodelk(0,0,DATA_DOMAIN)`
+
+* Metadata transactions (chown/chmod) also take inode locks but on a special range on metadata domain,
+ i.e.`(LLONG_MAX-1 , 0, METADATA_DOMAIN).`
+
+* Entry transactions (create, mkdir, rmdir,unlink, symlink, link,rename) take entrylk on `(name, parent inode)`.
+
+
+2)For self heal:
+-------------
+* For Metadata self-heal, it is the same. i.e.`inodelk(LLONG_MAX-1 , 0, METADATA_DOMAIN)`.
+* For Entry self-heal, it is `entrylk(NULL name, parent inode)`. Specifying NULL for the name takes full lock on the directory referred to by the inode.
+* For data self-heal, there is a bit of history as to how locks evolved:
+
+### Initial version (say version 1) :
+There was no concept of selfheal daemon (shd). Only client lookups triggered heals. so AFR always took `inodelk(0,0,DATA_DOMAIN)` for healing. The issue with this approach was that when heal was in progress, I/O from clients was blocked .
+
+### version 2:
+shd was introduced. We needed to allow I/O to go through when heal was going,provided the ranges did not overlap. To that extent, the following approach was adopted:
+
++ 1.shd takes (full inodelk in DATA_DOMAIN). Thus client FOPS are blocked and cannot modify changelog-xattrs
++ 2.shd inspects xattrs to determine source/sink
++ 3.shd takes a chunk inodelk(0-128kb) again in DATA_DOMAIN (locks xlator allows overlapping locks if lock owner is the same).
++ 4.unlock full lock
++ 5.heal
++ 6.take next chunk lock(129-256kb)
++ 7.unlock 1st chunk lock, heal the second chunk and so on.
+
+
+Thus after 4, any client FOP could write to regions that was not currently under heal. The exception was truncate (to size 0) because it needs full file lock and will always block because some chunk is always under lock by the shd until heal completes.
+
+Another issue was that 2 shds could run in parallel. Say SHD1 and SHD2 compete for step 1. Let SHD1 win. It proceeds and completes step 4. Now SHD2 also succeeds in step 1, continues all steps. Thus at the end both shds will decrement the changelog leading to negative values in it)
+
+### version 3
+To prevent parallel self heals, another domain was introduced, let us call it SELF_HEAL_DOMAIN. With this domain, the following approach was adopted and is **the approach currently in use**:
+
++ 1.shd takes (full inodelk on SELF_HEAL_DOMAIN)
++ 2.shd takes (full inodelk on DATA_DOMAIN)
++ 3.shd inspects xattrs to determine source/sink
++ 4.unlock full lock on DATA_DOMAIN
++ 5.take chunk lock(0-128kb) on DATA_DOMAIN
++ 6.heal
++ 7.take next chunk lock(129-256kb) on DATA_DOMAIN
++ 8.unlock 1st chunk lock, heal and so on.
++ 9.Finally release full lock on SELF_HEAL_DOMAIN
+
+Thus until one shd completes step 9, another shd cannot start step 1, solving the problem of simultaneous heals.
+Note that the issue of truncate (to zero) FOP hanging still remains.
+Also there are multiple network calls involved in this scheme. (lock,heal(ie read+write), unlock) per chunk. i.e 4 calls per chunk.
+
+### version 4 (ToDo)
+Some improvements that need to be made in version 3:
+* Reduce network calls using piggy backing.
+* After taking chunk lock and healing, we need to unlock the lock before locking the next chunk. This gives a window for any pending truncate FOPs to succeed. If truncate succeeds, the heal of next chunk will fail (read returns zero)
+and heal is stopped. *BUT* there is **yet another** issue:
+
+* shd does steps 1 to 4. Let's assume source is brick b1, sink is brick b2 . i.e xattrs are (0,1) and (0,0) on b1 and b2 respectively. Now before shd takes (0-128kb) lock, a client FOP takes it.
+It modifies data but the FOP succeeds only on brick 2. writev returns success, and the attrs now read (0,1) (1,0). SHD takes over and heals. It had observed (0,1),(0,0) earlier
+and thus goes ahead and copies stale 128Kb from brick 1 to brick2. Thus as far as application is concerned, `writev` returned success but bricks have stale data.
+What needs to be done is `writev` must return success only if it succeeded on atleast one source brick (brick b1 in this case). Otherwise The heal still happens in reverse direction but as far as the application is concerned, it received an error.
+
+### Note on lock **domains**
+We have used conceptual names in this document like DATA_DOMAIN/ METADATA_DOMAIN/ SELF_HEAL_DOMAIN. In the code, these are mapped to strings that are based on the AFR xlator name like so:
+
+DATA_DOMAIN --->"vol_name-replicate-n"
+
+METADATA_DOMAIN --->"vol_name-replicate-n:metadata"
+
+SELF_HEAL_DOMAIN -->"vol_name-replicate-n:self-heal"
+
+where vol_name is the name of the volume and 'n' is the replica subvolume index (starting from 0).

+Self-Heal Daemon
+================
+The self-heal daemon (shd) is a glusterfs process that is responsible for healing files in a replicate/ disperse gluster volume.
+Every server (brick) node of the volume runs one instance of the shd. So even if one node contains replicate/ disperse bricks of
+multiple volumes, it would be healed by the same shd.
+
+This document only describes how the shd works for replicate (AFR) volumes.
+
+The shd is launched by glusterd when the volume starts (only if the volume includes a replicate configuration). The graph
+of the shd process in every node contains the following: The io-stats which is the top most xlator, its children being the
+replicate xlators (subvolumes) of *only* the bricks present in that particular node, and finally *all* the client xlators that are the children of the replicate xlators.
+
+The shd does two types of self-heal crawls: Index heal and Full heal. For both these types of crawls, the basic idea is the same:
+For each file encountered while crawling, perform metadata, data and entry heals under appropriate locks.
+* An overview of how each of these heals is performed is detailed in the 'Self-healing' section of *doc/features/afr-v1.md*
+* The different file locks which the shd takes for each of these heals is detailed in *doc/developer
+-guide/afr-locks-evolution.md*
+
+Metadata heal refers to healing extended attributes, mode and permissions of a file or directory.
+Data heal refers to healing the file contents.
+Entry self-heal refers to healing entries inside a directory.

+The index heal is done:
+ a) Every 600 seconds (can be changed via the `cluster.heal-timeout` volume option)
+ b) When it is explicitly triggered via the `gluster vol heal <VOLNAME>` command
+ c) Whenever a replica brick that was down comes back up.
+
+Only one heal can be in progress at one time, irrespective of reason why it was triggered. If another heal is triggered before the first one completes, it will be queued.
+Only one heal can be queued while the first one is running. If an Index heal is queued, it can be overridden by queuing a Full heal and not vice-versa. Also, before processing
+each entry in index heal, a check is made if a full heal is queued. If it is, then the index heal is aborted so that the full heal can proceed.
+
+In index heal, each shd reads the entries present inside .glusterfs/indices/xattrop/ folder and triggers heal on each entry with appropriate locks.
+The .glusterfs/indices/xattrop/ directory contains a base entry of the name "xattrop-<virtual-gfid-string>". All other entries are hardlinks to the base entry. The
+*names* of the hardlinks are the gfid strings of the files that may need heal.
+
+When a client (mount) performs an operation on the file, the index xlator present in each brick process adds the hardlinks in the pre-op phase of the FOP's transaction
+and removes it in post-op phase if the operation is successful. Thus if an entry is present inside the .glusterfs/indices/xattrop/ directory when there is no I/O
+happening on the file, it means the file needs healing (or atleast an examination if the brick crashed after the post-op completed but just before the removal of the hardlink).
+
+#### Index heal steps:
+<pre><code>
+In shd process of *each node* {
+ opendir +readdir (.glusterfs/indices/xattrop/)
+ for each entry inside it {
+ self_heal_entry() //Explained below.
+ }
+}
+</code></pre>
+
+<pre><code>
+self_heal_entry() {
+ Call syncop_lookup(replicae subvolume) which eventually does {
+ take appropriate locks
+ determine source and sinks from AFR changelog xattrs
+ perform whatever heal is needed (any of metadata, data and entry heal in that order)
+ clear changelog xattrs and hardlink inside .glusterfs/indices/xattrop/
+ }
+}
+</code></pre>
+
+Note:
+* If the gfid hardlink is present in the .glusterfs/indices/xattrop/ of both replica bricks, then each shd will try to heal the file but only one of them will be able to proceed due to the self-heal domain lock.
+
+* While processing entries inside .glusterfs/indices/xattrop/, if shd encounters an entry whose parent is yet to be healed, it will skip it and it will be picked up in the next crawl.
+
+* If a file is in data/ metadata split-brain, it will not be healed.
+
+* If a directory is in entry split-brain, a conservative merge will be performed, wherein after the merge, the entries of the directory will be a union of the entries in the replica pairs.
+
+Full heal
+=========
+A full heal is triggered by running `gluster vol heal <VOLNAME> full`. This command is usually run in disk replacement scenarios where the entire data is to be copied from one of the healthy bricks of the replica to the brick that was just replaced.
+
+Unlike the index heal which runs on the shd of every node in a replicate subvolume, the full heal is run only on the shd of one node per replicate subvolume: the node having the highest UUID.
+i.e In a 2x2 volume made of 4 nodes N1, N2, N3 and N4, If UUID of N1>N2 and UUID N4 >N3, then the full crawl is carried out by the shds of N1 and N4.(Node UUID can be found in `/var/lib/glusterd/glusterd.info`)
+
+The full heal steps are almost identical to the index heal, except the heal is performed on each replica starting from the root of the volume:
+<pre><code>
+In shd process of *highest UUID node per replica* {
+ opendir +readdir ("/")
+ for each entry inside it {
+ self_heal_entry()
+ if (entry == directory) {
+ /* Recurse*/
+ again opendir+readdir (directory) followed by self_heal_entry() of each entry.
+ }
+
+ }
+}
+</code></pre>

+cluster/afr translator
+======================
+
+Locking
+-------
+
+Before understanding replicate, one must understand two internal FOPs:
+
+### `GF_FILE_LK`
+
+This is exactly like `fcntl(2)` locking, except the locks are in a
+separate domain from locks held by applications.
+
+### `GF_DIR_LK (loc_t *loc, char *basename)`
+
+This allows one to lock a name under a directory. For example,
+to lock /mnt/glusterfs/foo, one would use the call:
+
+```
+GF_DIR_LK ({loc_t for "/mnt/glusterfs"}, "foo")
+```
+
+If one wishes to lock *all* the names under a particular directory,
+supply the basename argument as `NULL`.
+
+The locks can either be read locks or write locks; consult the
+function prototype for more details.
+
+Both these operations are implemented by the features/locks (earlier
+known as posix-locks) translator.
+
+Basic design
+------------
+
+All FOPs can be classified into four major groups:
+
+### inode-read
+
+Operations that read an inode's data (file contents) or metadata (perms, etc.).
+
+access, getxattr, fstat, readlink, readv, stat.
+
+### inode-write
+
+Operations that modify an inode's data or metadata.
+
+chmod, chown, truncate, writev, utimens.
+
+### dir-read
+
+Operations that read a directory's contents or metadata.
+
+readdir, getdents, checksum.
+
+### dir-write
+
+Operations that modify a directory's contents or metadata.
+
+create, link, mkdir, mknod, rename, rmdir, symlink, unlink.
+
+Some of these make a subgroup in that they modify *two* different entries:
+link, rename, symlink.
+
+### Others
+
+Other operations.
+
+flush, lookup, open, opendir, statfs.
+
+Algorithms
+----------
+
+Each of the four major groups has its own algorithm:
+
+### inode-read, dir-read
+
+1. Send a request to the first child that is up:
+ * if it fails:
+ * try the next available child
+ * if we have exhausted all children:
+ * return failure
+
+### inode-write
+
+ All operations are done in parallel unless specified otherwise.
+
+1. Send a ``GF_FILE_LK`` request on all children for a write lock on the
+ appropriate region
+ (for metadata operations: entire file (0, 0) for writev:
+ (offset, offset+size of buffer))
+ * If a lock request fails on a child:
+ * unlock all children
+ * try to acquire a blocking lock (`F_SETLKW`) on each child, serially.
+ If this fails (due to `ENOTCONN` or `EINVAL`):
+ Consider this child as dead for rest of transaction.
+2. Mark all children as "pending" on all (alive) children (see below for
+meaning of "pending").
+ * If it fails on any child:
+ * mark it as dead (in transaction local state).
+3. Perform operation on all (alive) children.
+ * If it fails on any child:
+ * mark it as dead (in transaction local state).
+4. Unmark all successful children as not "pending" on all nodes.
+5. Unlock region on all (alive) children.
+
+### dir-write
+
+ The algorithm for dir-write is same as above except instead of holding
+ `GF_FILE_LK` locks we hold a GF_DIR_LK lock on the name being operated upon.
+ In case of link-type calls, we hold locks on both the operand names.
+
+"pending"
+---------
+
+The "pending" number is like a journal entry. A pending entry is an
+array of 32-bit integers stored in network byte-order as the extended
+attribute of an inode (which can be a directory as well).
+
+There are three keys corresponding to three types of pending operations:
+
+### `AFR_METADATA_PENDING`
+
+There are some metadata operations pending on this inode (perms, ctime/mtime,
+xattr, etc.).
+
+### `AFR_DATA_PENDING`
+
+There is some data pending on this inode (writev).
+
+### `AFR_ENTRY_PENDING`
+
+There are some directory operations pending on this directory
+(create, unlink, etc.).
+
+Self heal
+---------
+
+* On lookup, gather extended attribute data:
+ * If entry is a regular file:
+ * If an entry is present on one child and not on others:
+ * create entry on others.
+ * If entries exist but have different metadata (perms, etc.):
+ * consider the entry with the highest `AFR_METADATA_PENDING` number as
+ definitive and replicate its attributes on children.
+ * If entry is a directory:
+ * Consider the entry with the highest `AFR_ENTRY_PENDING` number as
+ definitive and replicate its contents on all children.
+ * If any two entries have non-matching types (i.e., one is file and
+ other is directory):
+ * Announce to the user via log that a split-brain situation has been
+ detected, and do nothing.
+* On open, gather extended attribute data:
+ * Consider the file with the highest `AFR_DATA_PENDING` number as
+ the definitive one and replicate its contents on all other
+ children.
+
+During all self heal operations, appropriate locks must be held on all
+regions/entries being affected.
+
+Inode scaling
+-------------
+
+Inode scaling is necessary because if a situation arises where an inode number
+is returned for a directory (by lookup) which was previously the inode number
+of a file (as per FUSE's table), then FUSE gets horribly confused (consult a
+FUSE expert for more details).
+
+To avoid such a situation, we distribute the 64-bit inode space equally
+among all children of replicate.
+
+To illustrate:
+
+If c1, c2, c3 are children of replicate, they each get 1/3 of the available
+inode space:
+
+------------- -- -- -- -- -- -- -- -- -- -- -- ---
+Child: c1 c2 c3 c1 c2 c3 c1 c2 c3 c1 c2 ...
+Inode number: 1 2 3 4 5 6 7 8 9 10 11 ...
+------------- -- -- -- -- -- -- -- -- -- -- -- ---
+
+Thus, if lookup on c1 returns an inode number "2", it is scaled to "4"
+(which is the second inode number in c1's space).
+
+This way we ensure that there is never a collision of inode numbers from
+two different children.
+
+This reduction of inode space doesn't really reduce the usability of
+replicate since even if we assume replicate has 1024 children (which would be a
+highly unusual scenario), each child still has a 54-bit inode space:
+$2^{54} \sim 1.8 \times 10^{16}$, which is much larger than any real
+world requirement.

+# Resource usage reduction in brick multiplexing
+
+Each brick is regresented with a graph of translators in a brick process.
+Each translator in the graph has its own set of threads and mem pools
+and other system resources allocations. Most of the times all these
+resources are not put to full use. Reducing the resource consumption
+of each brick is a problem in itself that needs to be addressed. The other
+aspect to it is, sharing of resources across brick graph, this becomes
+critical in brick multiplexing scenario. In this document we will be discussing
+only about the threads.
+
+If a brick mux process hosts 50 bricks there are atleast 600+ threads created
+in that process. Some of these are global threads that are shared by all the
+brick graphs, and others are per translator threads. The global threads like
+synctask threads, timer threads, sigwaiter, poller etc. are configurable and
+do not needs to be reduced. The per translator threads keeps growing as the
+number of bricks in the process increases. Each brick spawns atleast 10+
+threads:
+- io-threads
+- posix threads:
+ 1. Janitor
+ 2. Fsyncer
+ 3. Helper
+ 4. aio-thread
+- changelog and bitrot threads(even when the features are not enabled)
+
+## io-threads
+
+io-threads should be made global to the process, having 16+ threads for
+each brick does not make sense. But io-thread translator is loaded in
+the graph, and the position of io-thread translator decides from when
+the fops will be parallelised across threads. We cannot entirely move
+the io-threads to libglusterfs and say the multiplexing happens from
+the master translator or so. Hence, the io-thread orchestrator code
+is moved to libglusterfs, which ensures there is only one set of
+io-threads that is shared among the io-threads translator in each brick.
+This poses performance issues due to lock-contention in the io-threds
+layer. This also shall be addressed by having multiple locks instead of
+one global lock for io-threads.
+
+## Posix threads
+Most of the posix threads execute tasks in a timely manner, hence it can be
+replaced with a timer whose handler register a task to synctask framework, once
+the task is complete, the timer is registered again. With this we can eliminate
+the need of one thread for each task. The problem with using synctasks is
+the performance impact it will have due to make/swapcontext. For task that
+does not involve network wait, we need not do makecontext, instead the task
+function with arg can be stored and executed when a synctask thread is free.
+We need to implement an api in synctask to execute atomic tasks(no network wait)
+without the overhead of make/swapcontext. This will solve the performance
+impact associated with using synctask framework.
+
+And the other challenge, is to cancel all the tasks pending from a translator.
+This is important to cleanly detach brick. For this, we need to implement an
+api in synctask that can cancel all the tasks from a given translator.
+
+For future, this will be replced to use global thread-pool(once implemented).
+
+## Changelog and bitrot threads
+
+In the initial implementation, the threads are not created if the feature is
+not enabled. We need to share threads across changelog instances if we plan
+to enable these features in brick mux scenario.

+GlusterFS Coding Standards
+==========================
+
+Before you get started
+----------------------
+Before starting with other part of coding standard, install `clang-format`
+
+On Fedora:
+```
+$ dnf install clang
+```
+On debian/Ubuntu:
+```
+$ apt-get install clang
+```
+Once you are done with all the local changes, you need to run below set of commands,
+before submitting the patch for review.
+```
+$ git add $file # if any
+$ git commit -a -s -m "commit message"
+$ git show --pretty="format:" --name-only | grep -v "contrib/" | egrep "*\.[ch]$" | xargs clang-format -i
+$ git diff # see if there are any changes
+$ git commit -a --amend # get the format changes done
+$ ./submit-for-review.sh
+```
+
+
+Structure definitions should have a comment per member
+------------------------------------------------------
+
+Every member in a structure definition must have a comment about its purpose.
+The comment should be descriptive without being overly verbose. For pointer
+members, lifecycle concerns for the pointed-to object should be noted. For lock
+members, the relationship between the lock member and the other members it
+protects should be explicit.
+
+*Bad:*
+
+```
+gf_lock_t lock; /* lock */
+```
+
+*Good:*
+
+```
+DBTYPE access_mode; /* access mode for accessing
+ * the databases, can be
+ * DB_HASH, DB_BTREE
+ * (option access-mode <mode>)
+ */
+```
+
+Structure members should be aligned based on the padding requirements
+---------------------------------------------------------------------
+
+The compiler will make sure that structure members have optimum alignment,
+but at the expense of suboptimal padding. More important is to optimize the
+padding. The compiler won't do that for you.
+
+This also will help utilize the memory better
+
+*Bad:*
+```
+struct bad {
+ bool b; /* 0 */
+ /* 1..7 pad */
+ void *p; /* 8..15 */
+ char c; /* 16 */
+ char a[16]; /* 17..33 */
+ /* 34..39 pad */
+ int64_t ii; /* 40..47 */
+ int32_t i; /* 48..51 */
+ /* 52..55 pad */
+ int64_t iii; /* 56..63 */
+};
+```
+
+*Good:*
+```
+struct good {
+ int64_t ii; /* explicit 64-bit types */
+ void *p; /* may be 64- or 32-bit */
+ long l; /* may be 64- or 32-bit */
+ int i; /* 32-bit */
+ short s; /* 16-bit */
+ char c; /* 8-bit */
+ bool b; /* 8-bit */
+ char a[1024];
+);
+```
+Make sure the items with the most stringent alignment requirements will need
+to come earliest (ie, pointers and perhaps uint64_t etc), and those with less
+stringent alignment requirements at the end (uint16/uint8 and char). Also note
+that the long array (if any) should be at the end of the structure, regardless
+of the type.
+
+Also note, if your structure's overall size is crossing 1k-4k limit, it is
+recommended to mention the reason why the particular structure needs so much
+memory as a comment at the top.
+
+Use \_typename for struct tags and typename\_t for typedefs
+---------------------------------------------------------
+
+Being consistent here makes it possible to automate navigation from use of a
+type to its true definition (not just the typedef).
+
+*Bad:*
+
+```
+struct thing {...};
+struct thing_t {...};
+typedef struct _thing thing;
+```
+
+*Good:*
+
+```
+typedef struct _thing {...} thing_t;
+```
+
+No double underscores
+---------------------
+
+Identifiers beginning with double underscores are supposed to reserved for the
+compiler.
+
+http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf
+
+When you need to define inner/outer functions, use a different prefix/suffix.
+
+*Bad:*
+
+```
+void __do_something (void);
+
+void
+do_something (void)
+{
+ LOCK ();
+ __do_something ();
+ UNLOCK ();
+}
+```
+
+*Good:*
+
+```
+void do_something_locked (void);
+```
+
+Only use safe pointers in initializers
+----------------------------------------------------------
+
+Some pointers, such as `this` in a fop function, can be assumed to be non-NULL.
+However, other parameters and further-derived values might be NULL.
+
+*Good:*
+
+```
+pid_t pid = frame->root->pid;
+```
+
+
+*Bad:*
+
+```
+data_t *my_data = dict_get (xdata, "fubar");
+```
+
+No giant stack allocations
+--------------------------
+
+Synctasks have small finite stacks. To avoid overflowing these stacks, avoid
+allocating any large data structures on the stack. Use dynamic allocation
+instead.
+
+*Bad:*
+
+```
+gf_boolean_t port_inuse[65536]; /* 256KB, this actually happened */
+```
+
+NOTE: Ideal is to limit the stack array to less than 256 bytes.
+
+
+Character array initializing
+----------------------------
+
+It is recommended to keep the character array initializing to empty string.
+
+*Good:*
+```
+char msg[1024] = "";
+```
+
+Not so much recommended, even though it means the same.
+
+```
+char msg[1024] = {0,};
+```
+
+We recommend above to structure initialization.
+
+
+
+Validate all arguments to a function
+------------------------------------
+
+All pointer arguments to a function must be checked for `NULL`.
+A macro named `GF_VALIDATE_OR_GOTO` (in `common-utils.h`)
+takes two arguments; if the first is `NULL`, it writes a log message and
+jumps to a label specified by the second aergument after setting errno
+appropriately. There are several variants of this function for more
+specific purposes, and their use is recommended.
+
+*Bad:*
+
+```
+/* top of function */
+ret = dict_get (xdata, ...)
+```
+
+*Good:*
+
+```
+/* top of function */
+GF_VALIDATE_OR_GOTO(xdata,out);
+ret = dict_get (xdata, ...)
+```
+
+Never rely on precedence of operators
+-------------------------------------
+
+Never write code that relies on the precedence of operators to execute
+correctly. Such code can be hard to read and someone else might not
+know the precedence of operators as accurately as you do. This includes
+precedence of increment/decrement vs. field/subscript. The only exceptions are
+arithmetic operators (which have had defined precedence since before computers
+even existed) and boolean negation.
+
+*Bad:*
+
+```
+if (op_ret == -1 && errno != ENOENT)
+++foo->bar /* incrementing foo, or incrementing foo->bar? */
+a && b || !c
+```
+
+*Good:*
+
+```
+if ((op_ret == -1) && (errno != ENOENT))
+(++foo)->bar
+++(foo->bar)
+(a && b) || !c
+a && (b || !c)
+```
+
+Use exactly matching types
+--------------------------
+
+Use a variable of the exact type declared in the manual to hold the
+return value of a function. Do not use an 'equivalent' type.
+
+
+*Bad:*
+
+```
+int len = strlen (path);
+```
+
+*Good:*
+
+```
+size_t len = strlen (path);
+```
+
+Avoid code such as `foo->bar->baz`; check every pointer
+-------------------------------------------------------------
+
+Do not write code that blindly follows a chain of pointer references. Any
+pointer in the chain may be `NULL` and thus cause a crash. Verify that each
+pointer is non-null before following it. Even if `foo->bar` has been checked
+and is known safe, repeating it can make code more verbose and less clear.
+
+This rule includes `[]` as well as `->` because both dereference pointers.
+
+*Bad:*
+
+```
+foo->bar->field1 = value1;
+xyz = foo->bar->field2 + foo->bar->field3 * foo->bar->field4;
+foo->bar[5].baz
+```
+
+*Good:*
+
+```
+my_bar = foo->bar;
+if (!my_bar) ... return;
+my_bar->field1 = value1;
+xyz = my_bar->field2 + my_bar->field3 * my_bar->field4;
+```
+
+Document unchecked return values
+----------------------------------------------------
+
+In general, return values should be checked. If a function is being called
+for its side effects and the return value really doesn't matter, an explicit
+cast to void is required (to keep static analyzers happy) and a comment is
+recommended.
+
+*Bad:*
+
+```
+close (fd);
+do_important_thing ();
+```
+
+*Good (or at least OK):*
+
+```
+(void) sleep (1);
+```
+
+Gracefully handle failure of malloc (and other allocation functions)
+--------------------------------------------------------------------
+
+GlusterFS should never crash or exit due to lack of memory. If a
+memory allocation fails, the call should be unwound and an error
+returned to the user.
+
+*Use result args and reserve the return value to indicate success or failure:*
+
+The return value of every functions must indicate success or failure (unless
+it is impossible for the function to fail --- e.g., boolean functions). If
+the function needs to return additional data, it must be returned using a
+result (pointer) argument.
+
+*Bad:*
+
+```
+int32_t dict_get_int32 (dict_t *this, char *key);
+```
+
+*Good:*
+
+```
+int dict_get_int32 (dict_t *this, char *key, int32_t *val);
+```
+
+Always use the 'n' versions of string functions
+-----------------------------------------------
+
+Unless impossible, use the length-limited versions of the string functions.
+
+*Bad:*
+
+```
+strcpy (entry_path, real_path);
+```
+
+*Good:*
+
+```
+strncpy (entry_path, real_path, entry_path_len);
+```
+
+Do not use memset prior to sprintf/snprintf/vsnprintf etc...
+------------------------------------------------------------
+snprintf(and other similar string functions) terminates the buffer with a
+'\0'(null character). Hence, there is no need to do a memset before using
+snprintf. (Of course you need to account one extra byte for the null character
+in your allocation).
+
+Note: Similarly if you are doing pre-memory allocation for the buffer, use
+GF_MALLOC instead of GF_CALLOC, since the later is bit costlier.
+
+*Bad:*
+
+```
+char buffer[x];
+memset (buffer, 0, x);
+bytes_read = snprintf (buffer, sizeof buffer, "bad standard");
+```
+
+*Good:*
+```
+char buffer[x];
+bytes_read = snprintf (buffer, sizeof (buffer), "good standard");
+```
+
+And it is always to good initialize the char array if the string is static.
+
+E.g.
+```
+char buffer[] = "good standard";
+```
+
+No dead or commented code
+-------------------------
+
+There must be no dead code (code to which control can never be passed) or
+commented out code in the codebase.
+
+Function length or Keep functions small
+---------------------------------------
+
+We live in the UNIX-world where modules do one thing and do it well.
+This rule should apply to our functions also. If a function is very long, try splitting it
+into many little helper functions. The question is, in a coding
+spree, how do we know a function is long and unreadable. One rule of
+thumb given by Linus Torvalds is that, a function should be broken-up
+if you have 4 or more levels of indentation going on for more than 3-4
+lines.
+
+*Example for a helper function:*
+```
+static int
+same_owner (posix_lock_t *l1, posix_lock_t *l2)
+{
+ return ((l1->client_pid == l2->client_pid) &&
+ (l1->transport == l2->transport));
+}
+```
+
+Define functions as static
+--------------------------
+
+Declare functions as static unless they're exposed via a module-level API for
+use from other modules.
+
+No nested functions
+-------------------
+
+Nested functions have proven unreliable, e.g. as callbacks in code that uses
+ucontext (green) threads,
+
+Use inline functions instead of macros whenever possible
+--------------------------------------------------------
+
+Inline functions enforce type safety; macros do not. Use macros only for things
+that explicitly need to be type-agnostic (e.g. cases where one might use
+generics or templates in other languages), or that use other preprocessor
+features such as `#` for stringification or `##` for token pasting. In general,
+"static inline" is the preferred form.
+
+Avoid copypasta
+---------------
+
+Code that is copied and then pasted into multiple functions often creates
+maintenance problems later, e.g. updating all but one instance for a subsequent
+change. If you find yourself copying the same "boilerplate" many places,
+consider refactoring to use helper functions (including inline) or macros, or
+code generation.
+
+Ensure function calls wrap around after 80-columns
+--------------------------------------------------
+
+Place remaining arguments on the next line if needed.
+
+Functions arguments and function definition
+-------------------------------------------
+
+Place all the arguments of a function definition on the same line
+until the line goes beyond 80-cols. Arguments that extend beyind
+80-cols should be placed on the next line.
+
+Style issues
+------------
+
+### Brace placement
+
+Use K&R/Linux style of brace placement for blocks.
+
+*Good:*
+
+```
+int some_function (...)
+{
+ if (...) {
+ /* ... */
+ } else if (...) {
+ /* ... */
+ } else {
+ /* ... */
+ }
+
+ do {
+ /* ... */
+ } while (cond);
+}
+```
+
+### Indentation
+
+Use *eight* spaces for indenting blocks. Ensure that your
+file contains only spaces and not tab characters. You can do this
+in Emacs by selecting the entire file (`C-x h`) and
+running `M-x untabify`.
+
+To make Emacs indent lines automatically by eight spaces, add this
+line to your `.emacs`:
+
+```
+(add-hook 'c-mode-hook (lambda () (c-set-style "linux")))
+```
+
+### Comments
+
+Write a comment before every function describing its purpose (one-line),
+its arguments, and its return value. Mention whether it is an internal
+function or an exported function.
+
+Write a comment before every structure describing its purpose, and
+write comments about each of its members.
+
+Follow the style shown below for comments, since such comments
+can then be automatically extracted by doxygen to generate
+documentation.
+
+*Good:*
+
+```
+/**
+* hash_name -hash function for filenames
+* @par: parent inode number
+* @name: basename of inode
+* @mod: number of buckets in the hashtable
+*
+* @return: success: bucket number
+* failure: -1
+*
+* Not for external use.
+*/
+```
+
+### Indicating critical sections
+
+To clearly show regions of code which execute with locks held, use
+the following format:
+
+```
+pthread_mutex_lock (&mutex);
+{
+ /* code */
+}
+pthread_mutex_unlock (&mutex);
+```
+
+### Always use braces
+
+Even around single statements.
+
+*Bad:*
+
+```
+if (condition) action ();
+
+if (condition)
+ action ();
+```
+
+*Good:*
+
+```
+if (condition) {
+ action ();
+}
+```
+
+### Avoid multi-line conditionals
+
+These can be hard to read and even harder to modify later. Predicate functions
+and helper variables are always better for maintainability.
+
+*Bad:*
+
+```
+if ((thing1 && other_complex_condition (thing1, lots, of, args))
+ || (!thing2 || even_more_complex_condition (thing2))
+ || all_sorts_of_stuff_with_thing3) {
+ return;
+}
+
+```
+
+*Better:*
+
+```
+thing1_ok = predicate1 (thing1, lots, of, args
+thing2_ok = predicate2 (thing2);
+thing3_ok = predicate3 (thing3);
+
+if (!thing1_ok || !thing2_ok || !thing3_ok) {
+ return;
+}
+```
+
+*Best:*
+
+```
+if (thing1 && other_complex_condition (thing1, lots, of, args)) {
+ return;
+}
+if (!thing2 || even_more_complex_condition (thing2)) {
+ /* Note potential for a different message here. */
+ return;
+}
+if (all_sorts_of_stuff_with_thing3) {
+ /* And here too. */
+ return;
+}
+```
+
+### Use 'const' liberally
+
+If a value isn't supposed/expected to change, there's no cost to adding a
+'const' keyword and it will help prevent violation of expectations.
+
+### Avoid global variables (including 'static' auto variables)
+Almost all state in Gluster is contextual and should be contained in the
+appropriate structure reflecting its scope (e.g. `call\_frame\_t`, `call\_stack\_t`,
+`xlator\_t`, `glusterfs\_ctx\_t`). With dynamic loading and graph switches in play,
+each global requires careful consideration of when it should be initialized or
+reinitialized, when it might _accidentally_ be reinitialized, when its value
+might become stale, and so on. A few global variables are needed to serve as
+'anchor points' for these structures, and more exceptions to the rule might be
+approved in the future, but new globals should not be added to the codebase
+without explicit approval.
+
+## A skeleton fop function
+
+This is the recommended template for any fop. In the beginning come the
+initializations. After that, the 'success' control flow should be linear. Any
+error conditions should cause a `goto` to a label at the end. By convention
+this is 'out' if there is only one such label, but a cascade of such labels is
+allowable to support multi-stage cleanup. At that point, the code should detect
+the error that has occurred and do appropriate cleanup.
+
+```
+int32_t
+sample_fop (call_frame_t *frame, xlator_t *this, ...)
+{
+ char * var1 = NULL;
+ int32_t op_ret = -1;
+ int32_t op_errno = 0;
+ DIR * dir = NULL;
+ struct posix_fd * pfd = NULL;
+
+ VALIDATE_OR_GOTO (frame, out);
+ VALIDATE_OR_GOTO (this, out);
+
+ /* other validations */
+
+ dir = opendir (...);
+
+ if (dir == NULL) {
+ op_errno = errno;
+ gf_log (this->name, GF_LOG_ERROR,
+ "opendir failed on %s (%s)", loc->path,
+ strerror (op_errno));
+ goto out;
+ }
+
+ /* another system call */
+ if (...) {
+ op_errno = ENOMEM;
+ gf_log (this->name, GF_LOG_ERROR,
+ "out of memory :(");
+ goto out;
+ }
+
+ /* ... */
+
+ out:
+ if (op_ret == -1) {
+
+ /* check for all the cleanup that needs to be
+ done */
+
+ if (dir) {
+ closedir (dir);
+ dir = NULL;
+ }
+
+ if (pfd) {
+ FREE (pfd->path);
+ FREE (pfd);
+ pfd = NULL;
+ }
+ }
+
+ STACK_UNWIND (frame, op_ret, op_errno, fd);
+ return 0;
+}
+```

+## Git Commit Good Practice
+
+The following document is based on experience doing code development, bug troubleshooting and code review across a number of projects using Git. The document is mostly borrowed from [Open Stack](https://wiki.openstack.org/wiki/GitCommitMessages), but made more meaningful in the context of GlusterFS project.
+
+This topic can be split into two areas of concern
+
+* The structured set/split of the code changes
+* The information provided in the commit message
+
+### Executive Summary
+The points and examples that will be raised in this document ought to clearly demonstrate the value in splitting up changes into a sequence of individual commits, and the importance in writing good commit messages to go along with them. If these guidelines were widely applied it would result in a significant improvement in the quality of the GlusterFS Git history. Both a carrot & stick will be required to effect changes. This document intends to be the carrot by alerting people to the benefits, while anyone doing Gerrit code review can act as the stick ;-P
+
+In other words, when reviewing a change in Gerrit:
+* Do not simply look at the correctness of the code.
+* Review the commit message itself and request improvements to its content.
+* Look out for commits which are mixing multiple logical changes and require the submitter to split them into separate commits.
+* Ensure whitespace changes are not mixed in with functional changes.
+* Ensure no-op code refactoring is done separately from functional changes.
+
+And so on.
+
+It might be mentioned that Gerrit's handling of patch series is not entirely perfect. Let that not become a valid reason to avoid creating patch series. The tools being used should be subservient to developers needs, and since they are open source they can be fixed / improved. Software source code is "read mostly, write occassionally" and thus the most important criteria is to improve the long term maintainability by the large pool of developers in the community, and not to sacrifice too much for the sake of the single author who may never touch the code again.
+
+And now the long detailed guidelines & examples of good & bad practice
+
+### Structural split of changes
+The cardinal rule for creating good commits is to ensure there is only one "logical change" per commit. There are many reasons why this is an important rule:
+
+* The smaller the amount of code being changed, the quicker & easier it is to review & identify potential flaws.
+* If a change is found to be flawed later, it may be necessary to revert the broken commit. This is much easier to do if there are not other unrelated code changes entangled with the original commit.
+* When troubleshooting problems using Git's bisect capability, small well defined changes will aid in isolating exactly where the code problem was introduced.
+* When browsing history using Git annotate/blame, small well defined changes also aid in isolating exactly where & why a piece of code came from.
+
+#### Things to avoid when creating commits
+With the above points in mind, there are some commonly encountered examples of bad things to avoid
+
+* Mixing whitespace changes with functional code changes.
+
+The whitespace changes will obscure the important functional changes, making it harder for a reviewer to correctly determine whether the change is correct. Solution: Create 2 commits, one with the whitespace changes, one with the functional changes. Typically the whitespace change would be done first, but that need not be a hard rule.
+
+* Mixing two unrelated functional changes.
+
+Again the reviewer will find it harder to identify flaws if two unrelated changes are mixed together. If it becomes necessary to later revert a broken commit, the two unrelated changes will need to be untangled, with further risk of bug creation.
+
+* Sending large new features in a single giant commit.
+
+It may well be the case that the code for a new feature is only useful when all of it is present. This does not, however, imply that the entire feature should be provided in a single commit. New features often entail refactoring existing code. It is highly desirable that any refactoring is done in commits which are separate from those implementing the new feature. This helps reviewers and test suites validate that the refactoring has no unintentional functional changes.
+
+Even the newly written code can often be split up into multiple pieces that can be independently reviewed. For example, changes which add new internal fops or library functions, can be in self-contained commits. Again this leads to easier code review. It also allows other developers to cherry-pick small parts of the work, if the entire new feature is not immediately ready for merge. This will encourage the author & reviewers to think about the generic library functions' design, and not simply pick a design that is easier for their currently chosen internal implementation.
+
+The basic rule to follow is
+
+If a code change can be split into a sequence of patches/commits, then it should be split. Less is not more. More is more.
+
+##### Examples of bad practice
+
+TODO: Pick glusterfs specific example.
+
+
+##### Examples of good practice
+
+
+### Information in commit messages
+As important as the content of the change, is the content of the commit message describing it. When writing a commit message there are some important things to remember
+
+* Do not assume the reviewer understands what the original problem was.
+
+When reading bug reports, after a number of back & forth comments, it is often as clear as mud, what the root cause problem is. The commit message should have a clear statement as to what the original problem is. The bug is merely interesting historical background on /how/ the problem was identified. It should be possible to review a proposed patch for correctness without needing to read the bug ticket.
+
+* Do not assume the reviewer has access to external web services/site.
+
+In 6 months time when someone is on a train/plane/coach/beach/pub troubleshooting a problem & browsing Git history, there is no guarantee they will have access to the online bug tracker, or online blueprint documents. The great step forward with distributed SCM is that you no longer need to be "online" to have access to all information about the code repository. The commit message should be totally self-contained, to maintain that benefit.
+
+* Do not assume the code is self-evident/self-documenting.
+
+What is self-evident to one person, might be clear as mud to another person. Always document what the original problem was and how it is being fixed, for any change except the most obvious typos, or whitespace only commits.
+
+* Describe why a change is being made.
+
+A common mistake is to just document how the code has been written, without describing /why/ the developer chose to do it that way. By all means describe the overall code structure, particularly for large changes, but more importantly describe the intent/motivation behind the changes.
+
+* Read the commit message to see if it hints at improved code structure.
+
+Often when describing a large commit message, it becomes obvious that a commit should have in fact been split into 2 or more parts. Don't be afraid to go back and rebase the change to split it up into separate commits.
+
+* Ensure sufficient information to decide whether to review.
+
+When Gerrit sends out email alerts for new patch submissions there is minimal information included, principally the commit message and the list of files changes. Given the high volume of patches, it is not reasonable to expect all reviewers to examine the patches in detail. The commit message must thus contain sufficient information to alert the potential reviewers to the fact that this is a patch they need to look at.
+
+* The first commit line is the most important.
+
+In Git commits the first line of the commit message has special significance. It is used as email subject line, git annotate messages, gitk viewer annotations, merge commit messages and many more places where space is at a premium. As well as summarizing the change itself, it should take care to detail what part of the code is affected. eg if it is 'afr', 'dht' or any translator. Or in some cases, it can be touching all these components, but the commit message can be 'coverity:', 'txn-framework:', 'new-fop: ', etc.
+
+* Describe any limitations of the current code.
+
+If the code being changed still has future scope for improvements, or any known limitations then mention these in the commit message. This demonstrates to the reviewer that the broader picture has been considered and what tradeoffs have been done in terms of short term goals vs. long term wishes.
+
+* Do not include patch set-specific comments.
+
+In other words, if you rebase your change please don't add "Patch set 2: rebased" to your commit message. That isn't going to be relevant once your change has merged. Please do make a note of that in Gerrit as a comment on your change, however. It helps reviewers know what changed between patch sets. This also applies to comments such as "Added unit tests", "Fixed localization problems", or any other such patch set to patch set changes that don't affect the overall intent of your commit.
+
+**The main rule to follow is:**
+
+The commit message must contain all the information required to fully understand & review the patch for correctness. Less is not more. More is more.
+
+
+#### Including external references
+
+The commit message is primarily targeted towards human interpretation, but there is always some metadata provided for machine use. In the case of GlusterFS this includes at least the 'Change-id', "bug"/"feature" ID references and "Signed-off-by" tag (generated by 'git commit -s').
+
+The 'Change-id' line is a unique hash describing the change, which is generated by a Git commit hook. This should not be changed when rebasing a commit following review feedback, since it is used by Gerrit, to track versions of a patch.
+
+The 'bug' line can reference a bug in a few ways. Gerrit creates a link to the bug when viewing the patch on review.gluster.org so that reviewers can quickly access the bug/issue on Bugzilla or Github.
+
+**Fixes: bz#1601166** -- use 'Fixes: bz#NNNNN' if the commit is intended to fully fix and close the bug being referenced.
+**Fixes: #411** -- use 'Fixes: #NNN' if the patch fixes the github issue completely.
+
+**Updates: bz#1193929** -- use 'Updates: bz#NNNN' if the commit is only a partial fix and more work is needed.
+**Updates: #175** -- use 'Updates: #NNNN' if the commit is only a partial fix and more work is needed for the feature completion.
+
+We encourage the use of `Co-Authored-By: name <name@example.com>` in commit messages to indicate people who worked on a particular patch. It's a convention for recognizing multiple authors, and our projects would encourage the stats tools to observe it when collecting statistics.
+
+### Summary of Git commit message structure
+
+* Provide a brief description of the change in the first line.
+* The first line should be limited to 50 characters and should not end with a period.
+
+* Insert a single blank line after the first line.
+
+* Provide a detailed description of the change in the following lines, breaking paragraphs where needed.
+
+* Subsequent lines should be wrapped at 72 characters.
+
+Put the 'Change-id', 'Fixes bz#NNNNN' and 'Signed-off-by: <>' lines at the very end.

+
+How to introduce new daemons using daemon management framework
+==============================================================
+Glusterd manages GlusterFS daemons providing services like NFS, Proactive
+self-heal, Quota, User servicable snapshots etc. Following are some of the
+aspects that come under daemon management.
+
+Data members & functions of different management objects
+
+- **Connection Management**
+ - unix domain sockets based channel for internal communication
+ - rpc connection for the communication
+ - frame timeout value for UDS
+ - Methods - notify
+ - init, connect, termination, disconnect APIs can be invoked using the
+ connection management object
+
+- **Process Management**
+ - Name of the process
+ - pidfile to detect if the daemon is running
+ - loggging directory, log file, volfile, volfileserver & volfileid
+ - init, stop APIs can be invoked using the process management object
+
+- **Service Management**
+ - connection object
+ - process object
+ - online status
+ - Methods - manager, start, stop which can be abstracted as a common methods
+ or specific to service requirements
+ - init API can be invoked using the service management object
+
+ The above structures defines the skeleton of the daemon management framework.
+ Introduction of new daemons in GlusterFS needs to inherit these properties. Any
+ requirement specific to a daemon needs to be implemented in its own service
+ (for eg : snapd defines its own type glusterd_snapdsvc_t using glusterd_svc_t
+ and snapd specific data). New daemons will need to have its own service specific
+ code written in glusterd-<feature>-svc.h{c} and need to reuse the existing
+ framework.

+# Inode and dentry management in GlusterFS:
+
+## Background
+Filesystems internally refer to files and directories via inodes. Inodes
+are unique identifiers of the entities stored in a filesystem. Whenever an
+application has to operate on a file/directory (read/modify), the filesystem
+maps that file/directory to the right inode and start referring to that inode
+whenever an operation has to be performed on the file/directory.
+
+In GlusterFS a new inode gets created whenever a new file/directory is created
+OR when a successful lookup is done on a file/directory for the first time.
+Inodes in GlusterFS are maintained by the inode table which gets initiated when
+the filesystem daemon is started (both for the brick process as well as the
+mount process). Below are some important data structures for inode management.
+
+## Data-structure (inode-table)
+```
+struct _inode_table {
+ pthread_mutex_t lock;
+ size_t hashsize; /* bucket size of inode hash and dentry hash */
+ char *name; /* name of the inode table, just for gf_log() */
+ inode_t *root; /* root directory inode, with inode
+ number and gfid 1 */
+ xlator_t *xl; /* xlator to be called to do purge and
+ the xlator which maintains the inode table*/
+ uint32_t lru_limit; /* maximum LRU cache size */
+ struct list_head *inode_hash; /* buckets for inode hash table */
+ struct list_head *name_hash; /* buckets for dentry hash table */
+ struct list_head active; /* list of inodes currently active (in an fop) */
+ uint32_t active_size; /* count of inodes in active list */
+ struct list_head lru; /* list of inodes recently used.
+ lru.next most recent */
+ uint32_t lru_size; /* count of inodes in lru list */
+ struct list_head purge; /* list of inodes to be purged soon */
+ uint32_t purge_size; /* count of inodes in purge list */
+
+ struct mem_pool *inode_pool; /* memory pool for inodes */
+ struct mem_pool *dentry_pool; /* memory pool for dentrys */
+ struct mem_pool *fd_mem_pool; /* memory pool for fd_t */
+ int ctxcount; /* number of slots in inode->ctx */
+};
+```
+
+# Life-cycle
+```
+inode_table_new (size_t lru_limit, xlator_t *xl)
+```
+This is a function which allocates a new inode table. Usually the top xlators in
+the graph such as protocol/server (for bricks), fuse and nfs (for fuse and nfs
+mounts) and libgfapi do inode managements. Hence they are the ones which will
+allocate a new inode table by calling the above function.
+
+Each xlator graph in glusterfs maintains an inode table. So in fuse clients,
+whenever there is a graph change due to add brick/remove brick or
+addition/removal of some other xlators, a new graph is created which creates a
+new inode table.
+
+Thus an allocated inode table is destroyed only when the filesystem daemon is
+killed or unmounted.
+
+
+# what it contains.
+Inode table in glusterfs mainly contains a hash table for maintaining inodes.
+In general a file/directory is considered to be existing if there is a
+corresponding inode present in the inode table. If a inode for a file/directory
+cannot be found in the inode table, glusterfs tries to resolve it by sending a
+lookup on the entry for which the inode is needed. If lookup is successful, then
+a new inode correponding to the entry is added to the hash table present in the
+inode table. Thus an inode present in the hash-table means, its an existing
+file/directory within the filesystem. The inode table also contains the hash
+size of the hash table (as of now it is hard coded to 14057. The hash value of
+a inode is calculated using its gfid).
+
+Apart from the hash table, inode table also maintains 3 important list of inodes
+1. Active list:
+Active list contains all the active inodes (i.e inodes which are currently part
+of some fop).
+2. Lru list:
+Least recently used inodes list. A limit can be set for the size of the lru
+list. For bricks it is 16384 and for clients it is infinity.
+3. Purge list:
+List of all the inodes which have to be purged (i.e inodes which have to be
+deleted from the inode table due to unlink/rmdir/forget).
+
+And at last it also contains the mem-pool for allocating inodes, dentries so
+that frequent malloc/calloc and free of the data structures can be avoided.
+
+
+# Data structure (inode)
+```
+struct _inode {
+ inode_table_t *table; /* the table this inode belongs to */
+ uuid_t gfid; /* unique identifier of the inode */
+ gf_lock_t lock;
+ uint64_t nlookup;
+ uint32_t fd_count; /* Open fd count */
+ uint32_t ref; /* reference count on this inode */
+ ia_type_t ia_type; /* what kind of file */
+ struct list_head fd_list; /* list of open files on this inode */
+ struct list_head dentry_list; /* list of directory entries for this inode */
+ struct list_head hash; /* hash table pointers */
+ struct list_head list; /* active/lru/purge */
+
+ struct _inode_ctx *_ctx; /* place holder for keeping the
+ information about the inode by different xlators */
+};
+```
+As said above, inodes are internal way of identifying the files/directories. A
+inode uniquely represents a file/directory. A new inode is created whenever a
+create/mkdir/symlink/mknod operations are performed. Apart from that a new inode
+is created upon the successful fresh lookup of a file/directory. Say the
+filesystem contained some file "a" within root and the filesystem was
+unmounted. Now when glusterfs is mounted and some operation is perfomed on "/a",
+glusterfs tries to get the inode for the entry "a" with parent inode as
+root. But, since glusterfs just came up, it will not be able to find the inode
+for "a" and will send a lookup on "/a". If the lookup operation succeeds (i.e.
+the root of glusterfs contains an entry called "a"), then a new inode for "/a"
+is created and added to the inode table.
+
+Depending upon the situation, an inode can be in one of the 3 lists maintained
+by the inode table. If some fop is happening on the inode, then the inode will
+be present in the active inodes list maintained by the inode table. Active
+inodes are those inodes whose refcount is greater than zero. Whenever some
+operation comes on a file/directory, and the resolver tries to find the inode
+for it, it increments the refcount of the inode before returning the inode. The
+refcount of an inode can be incremented by calling the below function
+```
+inode_ref (inode_t *inode)
+```
+Any xlator which wants to operate on a inode as part of some fop (or wants the
+inode in the callback), should hold a ref on the inode.
+Once the fop is completed before sending the reply of the fop to the above
+layers , the inode has to be unrefed. When the refcount of an inode becomes
+zero, it is removed from the active inodes list and put into LRU list maintained
+by the inode table. Thus in short if some fop is happening on a file/directory,
+the corresponding inode will be in the active list or it will be in the LRU
+list.
+
+
+# Life Cycle
+
+A new inode is created whenever a new file/directory/symlink is created OR a
+successful lookup of an existing entry is done. The xlators which does inode
+management (as of now protocol/server, fuse, nfs, gfapi) will perform inode_link
+operation upon successful lookup or successful creation of a new entry.
+```
+inode_link (inode_t *inode, inode_t *parent, const char *name,
+ struct iatt *buf);
+```
+inode_link actually adds the inode to the inode table (to be precise it adds
+the inode to the hash table maintained by the inode table. The hash value is
+calculated based on the gfid). Copies the gfid to the inode (the gfid is
+present in the iatt structure). Creates a dentry with the new name.
+
+A inode is removed from the inode table and eventually destroyed when unlink
+or rmdir operation is performed on a file/directory, or the the lru limit of
+the inode table has been exceeded.
+
+# Data structure (dentry)
+```
+
+struct _dentry {
+ struct list_head inode_list; /* list of dentries of inode */
+ struct list_head hash; /* hash table pointers */
+ inode_t *inode; /* inode of this directory entry */
+ char *name; /* name of the directory entry */
+ inode_t *parent; /* directory of the entry */
+};
+```
+A dentry is the presence of an entry for a file/directory within its parent
+directory. A dentry usually points to the inode to which it belongs to. In
+glusterfs a dentry contains the following fields.
+1. a hook using which it can add itself to the list of
+the dentries maintained by the inode to which it points to.
+2. A hash table pointer.
+3. Pointer to the inode to which it belongs to.
+4. Name of the dentry
+5. Pointer to the inode of the parent directory in which the dentry is present
+
+A new dentry is created when a new file/directory/symlink is created or a hard
+link to an existing file is created.
+```
+__dentry_create (inode_t *inode, inode_t *parent, const char *name);
+```
+A dentry holds a refcount on the parent
+directory so that the parent inode is never removed from the active inode's list
+and put to the lru list (If the lru limit of the lru list is exceeded, there is
+a chance of parent inode being destroyed. To avoid it, the dentries hold a
+reference to the parent inode). A dentry is removed whenevern a unlink/rmdir
+is perfomed on a file/directory. Or when the lru limit has been exceeded, the
+oldest inodes are purged out of the inode table, during which all the dentries
+of the inode are removed.
+
+Whenever a unlink/rmdir comes on a file/directory, the corresponding inode
+should be removed from the inode table. So upon unlink/rmdir, the inode will
+be moved to the purge list maintained by the inode table and from there it is
+destroyed. To be more specific, if a inode has to be destroyed, its refcount
+and nlookup count both should become 0. For refcount to become 0, the inode
+should not be part of any fop (there should not be any open fds). Or if the
+inode belongs to a directory, then there should not be any fop happening on the
+directory and it should not contain any dentries within it. For nlookup count to
+become zero, a forget has to be sent on the inode with nlookup count set to 0 as
+an argument. For fuse clients, forget is sent by the kernel itself whenever a
+unlink/rmdir is performed. But for brick processes, upon unlink/rmdir, the
+protocol/server itself has to do inode_forget. Whenever the inode has to be
+deleted due to file removal or lru limit being exceeded the inode is retired
+(i.e. all the dentries of the inode are deleted and the inode is moved to the
+purge list maintained by the inode table), the nlookup count is set to 0 via
+inode_forget api. The inode table, then prunes all the inodes from the purge
+list by destroying the inode contexts maintained by each xlator.
+```
+unlinking of the dentry is done via inode_unlink;
+
+void
+inode_unlink (inode_t *inode, inode_t *parent, const char *name);
+```
+If the inode has multiple hard links, then the unlink operation performed by
+the application results just in the removal of the dentry with the name provided
+by the application. For the inode to be removed, all the dentries of the inode
+should be unlinked.

+# Iobuf-pool
+## Datastructures
+### iobuf
+Short for IO Buffer. It is one allocatable unit for the consumers of the IOBUF
+API, each unit hosts @page_size(defined in arena structure) bytes of memory. As
+initial step of processing a fop, the IO buffer passed onto GlusterFS by the
+other applications (FUSE VFS/ Applications using gfapi) is copied into GlusterFS
+space i.e. iobufs. Hence Iobufs are mostly allocated/deallocated in Fuse, gfapi,
+protocol xlators, and also in performance xlators to cache the IO buffers etc.
+```
+struct iobuf {
+ union {
+ struct list_head list;
+ struct {
+ struct iobuf *next;
+ struct iobuf *prev;
+ };
+ };
+ struct iobuf_arena *iobuf_arena;
+
+ gf_lock_t lock; /* for ->ptr and ->ref */
+ int ref; /* 0 == passive, >0 == active */
+
+ void *ptr; /* usable memory region by the consumer */
+
+ void *free_ptr; /* in case of stdalloc, this is the
+ one to be freed not the *ptr */
+};
+```
+
+### iobref
+There may be need of multiple iobufs for a single fop, like in vectored read/write.
+Hence multiple iobufs(default 16) are encapsulated under one iobref.
+```
+struct iobref {
+ gf_lock_t lock;
+ int ref;
+ struct iobuf **iobrefs; /* list of iobufs */
+ int alloced; /* 16 by default, grows as required */
+ int used; /* number of iobufs added to this iobref */
+};
+```
+### iobuf_arenas
+One region of memory MMAPed from the operating system. Each region MMAPs
+@arena_size bytes of memory, and hosts @arena_size / @page_size IOBUFs.
+The same sized iobufs are grouped into one arena, for sanity of access.
+
+```
+struct iobuf_arena {
+ union {
+ struct list_head list;
+ struct {
+ struct iobuf_arena *next;
+ struct iobuf_arena *prev;
+ };
+ };
+
+ size_t page_size; /* size of all iobufs in this arena */
+ size_t arena_size; /* this is equal to
+ (iobuf_pool->arena_size / page_size)
+ * page_size */
+ size_t page_count;
+
+ struct iobuf_pool *iobuf_pool;
+
+ void *mem_base;
+ struct iobuf *iobufs; /* allocated iobufs list */
+
+ int active_cnt;
+ struct iobuf active; /* head node iobuf
+ (unused by itself) */
+ int passive_cnt;
+ struct iobuf passive; /* head node iobuf
+ (unused by itself) */
+ uint64_t alloc_cnt; /* total allocs in this pool */
+ int max_active; /* max active buffers at a given time */
+};
+
+```
+### iobuf_pool
+Pool of Iobufs. As there may be many Io buffers required by the filesystem,
+a pool of iobufs are preallocated and kept, if these preallocated ones are
+exhausted only then the standard malloc/free is called, thus improving the
+performance. Iobuf pool is generally one per process, allocated during
+glusterfs_ctx_t init (glusterfs_ctx_defaults_init), currently the preallocated
+iobuf pool memory is freed on process exit. Iobuf pool is globally accessible
+across GlusterFs, hence iobufs allocated by any xlator can be accessed by any
+other xlators(unless iobuf is not passed).
+```
+struct iobuf_pool {
+ pthread_mutex_t mutex;
+ size_t arena_size; /* size of memory region in
+ arena */
+ size_t default_page_size; /* default size of iobuf */
+
+ int arena_cnt;
+ struct list_head arenas[GF_VARIABLE_IOBUF_COUNT];
+ /* array of arenas. Each element of the array is a list of arenas
+ holding iobufs of particular page_size */
+
+ struct list_head filled[GF_VARIABLE_IOBUF_COUNT];
+ /* array of arenas without free iobufs */
+
+ struct list_head purge[GF_VARIABLE_IOBUF_COUNT];
+ /* array of of arenas which can be purged */
+
+ uint64_t request_misses; /* mostly the requests for higher
+ value of iobufs */
+};
+```
+~~~
+The default size of the iobuf_pool(as of yet):
+1024 iobufs of 128Bytes = 128KB
+512 iobufs of 512Bytes = 256KB
+512 iobufs of 2KB = 1MB
+128 iobufs of 8KB = 1MB
+64 iobufs of 32KB = 2MB
+32 iobufs of 128KB = 4MB
+8 iobufs of 256KB = 2MB
+2 iobufs of 1MB = 2MB
+Total ~13MB
+~~~
+As seen in the datastructure iobuf_pool has 3 arena lists.
+
+- arenas:
+The arenas allocated during iobuf_pool create, are part of this list. This list
+also contains arenas that are partially filled i.e. contain few active and few
+passive iobufs (passive_cnt !=0, active_cnt!=0 except for initially allocated
+arenas). There will be by default 8 arenas of the sizes mentioned above.
+- filled:
+If all the iobufs in the arena are filled(passive_cnt = 0), the arena is moved
+to the filled list. If any of the iobufs from the filled arena is iobuf_put,
+then the arena moves back to the 'arenas' list.
+- purge:
+If there are no active iobufs in the arena(active_cnt = 0), the arena is moved
+to purge list. iobuf_put() triggers destruction of the arenas in this list. The
+arenas in the purge list are destroyed only if there is atleast one arena in
