libglusterfs: Move devel headers under glusterfs directory

2018-12-05T21:47:04+00:00

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.

Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation <> in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs

This change although big, is just moving around the headers and
making it correct when including these headers from other sources.

This helps us correctly include libglusterfs includes without
namespace conflicts.

glusterd: Add option to get all volume options through get-state CLI

2017-07-25T05:04:47+00:00

This commit makes the get-state CLI capable to returning the values
for all volume options for all volumes. This is similar to what you
get when you issue a `gluster volume get  all` command.

This is the new usage for the get-state CLI:

 # gluster get-state [] [[odir ] \
[file ]] [detail|volumeoptions]

glusterd: Add client details to get-state output

2017-04-13T03:43:08+00:00

This commit optionally adds client details corresponding to the
locally running bricks to the get-state output. Since getting
the client details involves sending RPC requests to the respective
local bricks, this is a relatively more costly operation. These
client details would be added to the get-state output only if the
get-state command is invoked with the 'detail' option.

This commit therefore also changes the get-state CLI usage. The
modified usage is as follows:

 # gluster get-state [] [[odir ] \
[file ]] [detail]

Tier: remove warning related to the enum

2017-02-07T05:12:29+00:00

PROBLEM: In the tier as a service patch the enums for tier (from
gf1_op_command and gf_defrag_command) are put into a single enum
gf_defrag_command which causes a warning that will make the build
fail.

FIX: send both the enum and eliminate the warning.

tier : Tier as a service

2017-01-17T04:49:47+00:00

tierd is implemented by separating from rebalance process.

The commands affected:

1) Attach tier will trigger this process instead of old one
2) tier start and tier start force will also trigger this process.
3) volume status [tier] will show tier daemon as a process instead
of task and normal tier status and tier detach status works.
4) tier stop implemented.
5) detach tier implemented separately along with new detach tier
status
6) volume tier volname status will work using the changes.
7) volume set works

This patch has separated the tier translator from the legacy
DHT rebalance code. It now sends the RPCs from the CLI
to glusterd separate to the DHT rebalance code.
The daemon is now a service, similar to the snapshot daemon,
and can be viewed using the volume status command.

The code for the validation and commit phase are the same
as the earlier tier validation code in DHT rebalance.

The “brickop” phase has been changed so that the status
command can use this framework.

The service management framework is now used.
DHT rebalance does not use this framework.

This service framework takes care of :

*) spawning the daemon, killing it and other such processes.
*) volume set options , which are written on the volfile.
*) restart and reconfigure functions. Restart is to restart
the daemon at two points
        1)after gluster goes down and comes up.
        2) to stop detach tier.
*) reconfigure is used to make immediate volfile changes.
By doing this, we don’t restart the daemon.
it has the code to rewrite the volfile for topological
changes too (which comes into place during add and remove brick).

With this patch the log, pid, and volfile are separated
and put into respective directories.

glusterd/quota: upgrade quota.conf file during an upgrade

2016-11-08T04:37:05+00:00

Problem
=======
When quota is enabled on 3.6, it will have quota conf version in quota.conf
as v1.1. This node gets upgraded to 3.7 but it will still have quota conf
version as v1.1 until a quota enable/disable/set limit is initiated. When
this is not initiated and when this node tries to peer probe a node which
is a fresh install of 3.7 (which will have quota conf version as v1.2), then this
will result in "Peer rejected" state. This patch fixes the issue.

Solution
========
When an upgrade happens from 3.6 to 3.7, quota.conf file needs
to be modified as well. With 3.6, in quota.conf the version will be
v1.1 and it needs to be changed to v1.2 from 3.7. This is because in
3.7, inode quota feature is introduced. So when an op-version bumpup
happens quota.conf needs to be upgraded with quota conf version v1.2
and all the 16 byte uuid needs to be changed to 17 bytes uuid as well.

Previously, when the cluster version is upgraded to 3.7, the quota.conf
got upgraded as well. But, the upgradation was done only when quota
enable/disable/set limit is done. With this patch, the upgradation is done
during a cluster op version bump up as well.

build: out-of-tree builds generates files in the wrong directory

2016-09-18T16:34:37+00:00

And minor cleanup of a few of the Makefile.am files while we're
at it.

Rewrite the make rules to do what xdrgen does. Now we can get rid
of xdrgen.

Note 1. netbsd6's sed doesn't do -i. Why are we still running
smoke tests on netbsd6 and not netbsd7? We barely support netbsd7
as it is.

Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with
libglusterfs? A cut-and-paste mistake? It has no references to
symbols in libglusterfs.

Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_
regex that matches the same lines as the _extended_ regex
"/#(ifndef|define|endif)/". To match the extended regex sed needs to
be run with -r on Linux; with -E on *BSD. However NetBSD's and
FreeBSD's sed helpfully also provide -r for compatibility. Using a
basic regex avoids having to use a kludge in order to run sed with
the correct option on OS X.

Note 4. Not copying the bit of xdrgen that inserts copyright/license
boilerplate. AFAIK it's silly to pretend that machine generated
files like these can be copyrighted or need license boilerplate.
The XDR source files have their own copyright and license; and
their copyrights are bound to be more up to date than old
boilerplate inserted by a script. From what I've seen of other
Open Source projects -- e.g. gcc and its C parser files generated
by yacc and lex -- IIRC they don't bother to add copyright/license
boilerplate to their generated files.

It appears that it's a long-standing feature of make (SysV, BSD,
gnu) for out-of-tree builds to helpfully pretend that the source
files it can find in the VPATH "exist" as if they are in the $cwd.
rpcgen doesn't work well in this situation and generates files
with "bad" #include directives.

E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`,
you get an #include directive in the generated .c file like this:

  ...
  #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h"
  ...

which (obviously) results in compile errors on out-of-tree build
because the (generated) header file doesn't exist at that location.
Compared to `rpcgen ./glusterfs3-xdr.x` where you get:

  ...
  #include "glusterfs3-xdr.h"
  ...

Which is what we need. We have to resort to some Stupid Make Tricks
like the addition of various .PHONY targets to work around the VPATH
"help".

Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/...
looks exactly like -I$(top_srcdir)/rpc/xdr/...  Don't be fooled though.
And don't delete the -I$(top_builddir)/rpc/xdr/... bits

feature/bitrot: Ondemand scrub option for bitrot

2016-08-25T21:39:38+00:00

The bitrot scrubber takes 'hourly/daily/biweekly/monthly'
as the values for 'scrub-frequency'. There is no way
to schedule the scrubbing when the admin wants it.

Ondemand scrubbing brings in the new option 'ondemand'
with which the admin can start scrubbing ondemand.
It starts the scrubbing immediately.

Ondemand scrubbing is successful only if the scrubber
is in 'Active (Idle)' (waiting for it's next frequency
cycle to start scrubbing). It is not entertained when
the scrubber is in 'Paused' or already running.

Here is the command line syntax.

gluster volume bitrot  scrub ondemand

snapshot/cli: Fix snapshot status xml output

snap status --xml errors out if a brick is down and
doesn't have pid. It is handled in the cli of the snap
status where "N/A" is displayed in such a scenario.
Handled the same in xml

snap status  --xml fails as the writer is
not initialised for the same. Using GF_SNAP_STATUS_TYPE_ITER
instead of GF_SNAP_STATUS_TYPE_SNAP for all snap's
status to differentiate between the two scenarios.

Added testcase volume-snapshot-xml.t to check
all snapshot commands xml outputs
