* libglusterfsclient: Avoid overwrite of inode found through ino numberShehjar Tikoo2009-07-231-3/+8
| | | | | | | | | | | | | | | | | In libgf_client_loc_fill, there is a possibility that all the ino, par and name are specified as non-NULL,non-zero args. So if an inode is located in the itable using the ino and the subsequent search for the inode using the par-ino and the file name does not result in an inode being found, the current code over-writes the inode that was found through the ino. The correct behaviour is to stop further searches if inode was already found using ino. Signed-off-by: Anand V.

* libglusterfsclient: Fill new loc with target's ino on linkShehjar Tikoo2009-07-231-0/+1
| | | | | | | | | | | | | | | In the loc_t of the link being created, we must fill in the inode of the old/target loc since this is a link operation. The inode_link to the new parent is called in libgf_client_link. This fixes a crash while running fileop over a fully-loaded dist-repl vol file. Ref: Bugzilla 161 Signed-off-by: Anand V.

* libglusterfsclient: Move DHT root-lookup workaround to initShehjar Tikoo2009-07-202-15/+12
| | | | | | | | | | | | | | | The workaround for the DHT requirement for a lookup on / needs to be done only once when the xlator graph is inited. Doing it on every path's lookup results in a major performance penalty when using distribute subvolumes upwards of 16, as reported by Avati. Ref: bug 152 Signed-off-by: Anand V.

* server: don't check for 'loc->parent' in entrylk and inodelk callsAmar Tumballi2009-07-171-4/+2
| | | | | | | | | | | | the lock operation on entry or inode is going to happen on only one inode, and it doesn't need dentry (with info on parent) for the lock operation to complete.

* Add a random initial offset to the afr round robin indexErick Tryzelaar2009-07-161-0/+3
| | | | | | | | | | | | | | | This patch helps to distribute load across an afr cluster when you have clients with the same access patterns, such as in benchmarking or map-reduce. By randomly offsetting the initial read_child_rr, clients should distribute reads over the afr nodes on average. A better solution could be to randomly shuffle the children instead of chosing a different initial offset. This should average the reads better across the nodes, but I'm not sure if there are any other consequences to doing this. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

| | | | | | | | | | | | | | | | each of the subvolume - This patch fixes bug #29. - Using separate copies of dictionaries also eliminates a potential bug in a setup consisting of afr with a posix and client, each having io-threads on top as children. Since posix_xattrop after performing required operations on the xattr array passed in dictionary, sets the result at the same key and in the same dictionary passed as input argument, there can be race conditions where in the results of the operation on posix-child can be sent to the other child as input argument for xattrop, which ofcourse is wrong.

* booster: Fix build problems with various libtool versionsShehjar Tikoo2009-06-302-12/+20
| | | | | | | | | | | | | | | | | | | | We've been facing a problem on some test systems where the booster.so is built by libtool as an executable rather than a dynamically loadable library. This problem is probably caused by it seeing a _init function in the source. This is the name of the libc initiliazation function so it could be the source of the problem. In any case, ld-preloadable libraries must not have a function called _init, instead they need to have __attribute ((constructor)) as the attribute for any and all functions the library wants executed before the program's main(). Our earlier approach was inherently problematic. This commit also cleans up the booster Makefile for better build behaviour. Credit: Harsha. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* libglusterfsclient: Fix glusterfs_mount-vmp search deadlockShehjar Tikoo2009-06-301-11/+20
| | | | | | | | | | | | | It is possible that the only translator in the libglusterfsclient tree is the posix. In that case, inside gluster_init, the graph init routines will need to call lstat on the posix subdirectory. Since even the glusterfs stack is running over booster, those calls will also first require vmp searching. BUT, the vmp lock is the same as the mount lock that was already taken when we entered glusterfs_mount, so a deadlock occurs. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* booster: Another attempt to fix 32 and 64 bit interoperabilityShehjar Tikoo2009-06-301-17/+27
| | | | | | | | | | | | With this patch, we might have finally arrived at a solution to the problem of function definition conflicts between our functions and those of libc while over-riding the libc versions.
