* libglusterfs/graph: pass correct translator pairs during reconfigureRaghavendra G2012-09-212-8/+18
| | | | | | | | | | | | | | | | | when we autoload xlators like acl, worm or mac-compatibility, they will be loaded on top of old graph. However, corresponding ones won't be present in new graph, since newgraph doesn't contain autoloaded translators. While passing xlator pairs to reconfigure, this fact should be accounted and correct xlator pairs should be passed instead of blindly passing oldgraph->first and newgraph->first.

* fuse-bridge: Pass unknown option down to fuseLubomir Rintel2012-09-121-0/+2
| | | | | | | | | | | | | | | | | | In Linux, certain "filesystem-specific" options (passed in string form in last argument to mount(2)), such as "rootcontext" or "context" are in fact common to all filesystems, including fuse. We should pass them down to the actual mount(2) call untouched. This is achieved by adding "fuse-mountopts" option to mount/fuse translator and adjusting the mount helper to propagate it with unrecognized options as they are encountered.

* storage/posix: Add or_array/and_array op for xattropPranith Kumar K2012-09-061-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: For set/reset of outcast (ALL changelog bits set per transaction type i.e. data/mdata/entry) from afr the capability of OR/AND in xattrop is needed in posix. Otherwise marking outcast will only be possible in self-heals where appropriate locks are held so that no other transaction is in progress, so exact number can be computed with which when XATTROP_ADD happens all bits will be set for that changelog. Fix: Implemented new xattrop-op OR_ARRAY, AND_ARRAY. Made checks in __add_array to work well with __or_array. Tests: From Afr code made an OR_ARRAY with ALL bits set and it reflected on the changelog xattrs. changelog incrementing did not have any effects on the all-set changelog. From Afr code made an AND_ARRAY with 0 and it reflected in the changelog xattrs.

| | | | | | | | | | | | | | | | | | | | * As of now "gluster volume set statedump-path" option sets the path of the statedump files for brick processes only. If SIGUSR1 is sent directly to all the gluster processes instead of using gluster cli command, then some of the statedumps will still be in /tmp (such as nfs server, glustershd). * This patch makes glusterfs processes search for the file /tmp/glusterdump.options and consider the options given in it. There if path key is set, then all the processes use that path when SIGUSR1 is sent or cli statedump command is executed. (Note that after taking statedump, if /tmp/glusterdump.options file is removed, then the default way is resumed).

* syncop: Added scaling down logicPranith Kumar K2012-08-202-5/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCA: Whenever the self-heald tests are done with more than 16 replicates The number of sync procs goes to > 2. These threads never die. Fix: Added scaling down logic in syncops so that the threads terminate themselves whenever the extra thread is idle for ~10 minutes. Minimum number of threads is still 2. Tests: Added logs for launching and terminating procs, made timeout to 6 seconds and ran volume-heal in a while loop. After logs say max number of procs are launched, attached process to gdb and verified that the number of syncop threads are 16. Stopped volume-heal and observed the logs for terminating the procs. Attached gdb to process again to check that the syncop threads are just 2. Did this 5 times. Things worked fine. Which procs were terminated was random. No proc structure was erroneously re-used. Procs never exceeded 16 and were never < 2.

* NetBSD swapcontext() portability fixEmmanuel Dreyfus2012-08-131-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Further analysis of the problem reveals some wrong conclusions I made before. NetBSD's swapcontext() preempts no thread. It alters the pthread private pointer, leading to multiple threads with the same pthread pointer. That led me to the wrong conclusion that thread were preempted. I guess this can be called a bug: NetBSD swapcontext() is incompatible with libpthread. Fortunately, there is a workaround, swapcontext() can be told to let the pthread private pointer untouched. This change just does that, fixing the crashes without sacrifying performances. There is just one problem: not all NetBSD ports have the capability to do that: at least ports using sh3, sparc, sparc64 and powerpc are left broken by this change. This problem will be addressed by upcoming fixes in NetBSD.

* libglusterfs: fix creation of spurious root inodesRaghavendra Bhat2012-07-241-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | Suppose lookup is sent on a newly created inode (gfid is root gfid), and in the call back inode_link is done, where if there is an inode already present in the inode table for that gfid, then we start using the present inode and the newly created inode supposedly gets destroyed when refcount comes down to zero through inode_unref calls. But inodes with root gfid are not unrefed. Now since in inode_link, the gfid has already been copied to the new inode and later the actual inode is found from the inode table, the new inode does not gets unrefed if its gfid is root gfid. Thus those spurious inodes with root gfid will be present throughout the lifetime of the filesystem. To fix this first search the inode table for an inode, with the gfid, present in the stat structure received as an argument. If the inode is not found, then copy the gfid to the newly created inode. Now whenever unref is called on on the new inode it gets unrefed and thus eventually gets destroyed Change-Id: I0f25f0a8dca3245abda1c322c216f063b52cf842 BUG: 841188 Signed-off-by: Raghavendra Bhat <raghavendra@redhat.com> Reviewed-on: http://review.gluster.com/3716 Reviewed-by: Amar Tumballi <amarts@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>

* glusterfs_ctx_t: un-globalize the filesystem contextAnand Avati2012-07-1713-84/+65
| | | | | | | | | | | | | | | | | | | | | | | | 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).

* libglusterfs,mount/fuse: implement gidcache mechanism in fuse-bridgeBrian Foster2012-07-174-2/+237
| | | | | | | | | | | | | | | | | | | | | | | | | | This change genericizes the cache mechanism implemented in commit 8efd2845 into libglusterfs/src/gidcache.[ch] and adds fuse-bridge as a client. The cache mechanism is fundamentally equivalent, with some minor changes: - Change cache key from uid_t to uint64_t. - Modify the cache add logic to locate and use an entry with a matching ID, should it already exist. This addresses a bug in the existing mechanism where an expired entry supercedes a newly added entry in lookup, causing repeated adds and flushing of a cache bucket. The fuse group cache is disabled by default. It can be enabled via the 'gid-timeout' fuse-bridge translator option and accompanying mount option (i.e., '-o gid-timeout=1' for a 1s entry timeout).

This option improves local caching through the page cache and native client. This change defines a new 'invalidate' translator callback to identify when an inode's cache mapping has been determined to be invalid. md-cache implements the policy to detect and invoke inode invalidations. fuse-bridge and io-cache implement invalidate handlers to invalidate the respective caches (page cache in the case of fuse).

| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | There is a possibility that the backend FS (like XFS) can allocate blocks beyond EOF for better performance reasons, which results in 'st_blocks' with higher values than what is consumed by the file descriptor. This would break few logic inside GlusterFS, like quota behavior etc, thus we need the exact number of blocks which are consumed by the file to the higher layers inside GlusterFS.
