libglusterfsclient: Avoid overwrite of inode found through ino number

2009-07-23T22:20:16+00:00

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.

libglusterfsclient: Fill new loc with target's ino on link

2009-07-23T22:20:12+00:00

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.

libglusterfsclient: Fake a fsid for every VMP

2009-07-20T21:29:41+00:00

This is needed to work around the replicate behaviour of
possibly returning device number for the same file from

different subvolumes.

libglusterfsclient: Move DHT root-lookup workaround to init

2009-07-20T21:29:37+00:00

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.

Do not failover readdir in replicate

Backport of http://patches.gluster.com/patch/561/ to release-2.0

Also, the failover version of afr_readdir_cbk is buggy and
crashes when it is called after a failover inevitably

server: don't check for 'loc->parent' in entrylk and inodelk calls

2009-07-17T21:05:32+00:00

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. Hence, in server_{inode,entry}lk() calls
after server_loc_fill, we -should not- be checking for parent inode.

future plan is to have httpd use booster and libglusterfsclient
instead.

change mount.glusterfs.in to work with non-bash shells too.

2009-07-17T21:05:28+00:00

removed 'fuction ' prefix to function definitions which was very
much /bin/bash specific.
