* glusterd: Removed pattern match lookup logic on volume optionsKrutika Dhananjay2012-09-051-43/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In light of the comments received on the following patch, http://review.gluster.com/#change,3860 this change knocks off the pattern match lookup logic that once enabled wildcard entries to be used for volume options. Here's a bit on the history of the macro "pattern_match_options", coming straight from the author's(Csaba) mouth: "So, the history of pattern_match_options is as follows: i. In the volume option table we used to be able to have wildcard entries like auth.addr.*.allow and there was a special lookup logic to support that, cf. http://github.com/gluster/glusterfs/commit/v3.1.0qa40~19 ii. However, later on we stopped using this mechanism: http://github.com/gluster/glusterfs/commit/v3.1.0qa40~9 iii. Later on we added the code that allowed the usage of option names both in fully qualified (<domain>.<specifier>) and short (<specifier>)forms: http://github.com/gluster/glusterfs/commit/v3.1.0qa41~10. At this point, maintaining support for wildcard table entries became more difficult (~ error prone), so that part was placed under the macro pattern_match_options and -- given that we made no use of the feature -- a simple direct lookup logic was introduced. I chose to keep the pattern matching logic in the code because I was not really sure about the future of it and thought we might want wildcarded table entries later. ..."

| | | | | | | | | | | | | | | | | | | | | | | | So far there has been a global glusterfs_ctx_t object which represents the running instance of the filesystem (client or server). It contains the various graphs, connection to the management daemon over which new graphs are obtained, calls stacks issued on this filesystem, and a bunch of such things. With the introduction of libgfapi, it is no more true that there will be only one filesystem context in a process. Applications can be written to use libgfapi and obtain serveral instances of different filesystems/volumes in the same process. This involves messy untangling of assumptions inside libglusterfs that there would only be one global glusterfs_ctx_t and offload that assumption to glusterfsd/ and cli/ (where it is true).

* calls to dict_allocate_and_serialize() are not 64-bit cleanKaleb S. KEITHLEY2012-07-124-26/+20
| | | | | | | | | | | | | | | | | | | | | | | All calls to dict_allocate_and_serialize() pass the address of a 32-bit type, but must cast it to the 64-bit pointer type (size_t *). This happens to work on LE machines, but even if it's apparently benign, it's still a bug. On BE machines it is not benign. GF_PROTOCOL_DICT_SERIALIZE() hacks around it by creating a size_t temp var, but that's, well, a hack, IMO when you consider that all the callers are actually passing &<u_int>; the param should just be a u_int * and eliminate the buggy casts and the temp var in the macro. Nobody apparently uses the Fedora/EPEL PPC RPMs, but they might. People are trying to build gluster.org bits on SPARC and tripping over this.

| | | | | | | | | | | | | | | | | | | | glusterd_gsync_read_frm_status reads what is expected to be a NUL- terminated status string from the specified file, but makes two mistakes when trying to do the favor of trimming trailing spaces. Do not let a leading NUL byte of status cause us to read buf[-1] and possibly to clear that and any preceding "trailing" spaces. Do not let a blen-byte input (with no NUL byte) cause our use of strlen to access beyond the end of non-NUL-terminated buffer. I looked at this code because coverity reported that it was assuming a read-provided buffer to be NUL-terminated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | read subvolume is a nice option to set prefred read child if you have a replication over 2 datacenter. if you have 2 datacenter and have a distributed replication where one set of servers are in datacenter one and the other (the replicated) are in the other datacenter read-subvolume it not very handy since it goes over name and the subvolume name is different for each replication pair. i added a new option called read-subvolume-index which take the number of the subvolume to choose. 0 fo first , 1 for second and so on subvolume in every replication. this option can now be used in the --xlator-option mount option to choose the prefered read child for all replication at once. For Example on all clients in datacenter one you can use --xlator-option=volumename-replication-*.read-subvolume-index=0 to prefer read from the servers in datacenter one. when you expand or shrink the volume no changes are needed to the client config since the wildcard will set this option automatic on reconfigure.

* glusterd, cli: handle uuid conflicts in probe gracefullyRaghavendra Bhat2012-07-021-0/+15
| | | | | | | | | | | | | | | | | | | | | | | A commonly faced problem among glusterfs users is: after a fresh installation of glusterfs in a virtual machine, the VM image is cloned to make multiple instances of the server. This breaks glusterd because right after glusterfs installation on the first boot glusterd would have created the node UUID and this gets inherited into the clone. The result is wierd behavior at the time of peer probe where glusterd does not (yet) deal with UUID collisions in a user friendly way. With this patch the peer which got the probe request will compare the uuid of the machine which send the probe request with its own uuid and send the proper error to cli if the uuids are same.

* localtime and ctime are not MT-SAFEKaleb S. KEITHLEY2012-06-294-14/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a number of nit-level issues throughout the source with the use of localtime and ctime. While they apparently aren't causing too many problems, apart from the one in bz 828058, they ought to be fixed. Among the "real" problems that are fixed in this patch: 1) general localtime and ctime not MT-SAFE. There's a non-zero chance that another thread calling localtime (or ctime) will over-write the static data about to be used in another thread 2) localtime(& <64-bit-type>) or ctime(& <64-bit-type>) generally not a problem on 64-bit or little-endian 32-bit. But even though we probably have zero users on big-ending 32-bit platforms, it's still incorrect. 3) multiple nested calls passed as params. Last one wins, i.e. over- writes result of prior calls. 4) Inconsistent error handling. Most of these calls are for logging, tracing, or dumping. I submit that if an error somehow occurs in the call to localtime or ctime, the log/trace/dump still should still occur. 5) Appliances should all have their clocks set to UTC, and all log entries, traces, and dumps should use GMT. 6) fix strtok(), change to strtok_r() Other things this patch fixes/changes (that aren't bugs per se): 1) Change "%Y-%m-%d %H:%M:%S" and similar to their equivalent shorthand, e.g. "%F %T" 2) change sizeof(timestr) to sizeof timestr. sizeof is an operator, not a function. You don't use i +(32), why use sizeof(<var>). (And yes, you do use parens with sizeof(<type>).) 3) change 'char timestr[256]' to 'char timestr[32]' where appropriate. Per-thread stack is limited. Time strings are never longer than ~20 characters, so why waste 220+ bytes on the stack? Things this patch doesn't fix: 1) hodgepodge of %Y-%m-%d %H:%M:%S versus %Y/%m/%d-%H%M%S and other variations. It's not clear to me whether this ever matters, not to mention 3rd party log filtering tools may already rely on a particular format. Still it would be nice to have a single manifest constant and have every call to localtime/strftime consistently use the same format.

The elimination of holes in striped files eliminates space wasted via local filesystem preallocation heuristics and significantly improves read performance. Coalesce mode is implemented with a new 'coalesce' xlator option, which is user-configurable and disabled by default. The format of newly created files is marked with a new 'stripe-coalesce' xattr. Cluster/stripe handles/preserves the format of files regardless of the current mode of operation (i.e., a volume can simultaneously consist of coalesced and non-coalesced files). Files without the stripe-coalesce attribute are assumed to have the traditional format to provide backward compatibility. extras/stripe-merge: support traditional and coalesce stripe formats Update the stripe-merge recovery tool to handle the traditional and coalesced file formats. The format of the file is detected automatically (and verified) via the stripe-coalesce attributes.
