libglusterfsclient: don't destroy the iobuf pool during fini.

2009-09-29T01:57:21+00:00

- some of the iobufs in pool will be cached by io-cache and hence refcount
    will not be zero. Hence the assertion of ref being zero in
    __iobuf_arena_destroy fails. Commenting out iobuf_pool_destroy during fini, till
    we introduce proper cleanup in all translators, thereby allowing io-cache
    to release the buffers it has held.

libglusterfsclient: traverse the vmplist during fini only if any entries are mounted.

2009-09-29T01:57:18+00:00

- the vmplist.list is inited only during mounting of first entry. Hence doing
    a list traversal when no vmpentries are present, results in a segfault.

libglusterfsclient: Wait for all call pools to be destroyed

2009-09-24T08:19:39+00:00

This ensures that the process using libglusterfsclient does
not exit before all the fops and calls have been replied to.
It helps to ensure that the backends are in a sane state when
the program exits.

libglusterfsclient: Clean up fini and umount code paths

2009-09-24T08:19:35+00:00

This patch cleans up the umount and fini paths in preparation
to support waiting for unwind of all pending call frames.

Two misc fixes are:
1. Fix to avoid deadlock in _libgf_umount by
using _libgf_vmp_search_entry instead of
libgf_vmp_search_exact_entry since the latter tries to take a
lock already help by _libgf_umount.

2. Avoid a crash in _libgf_umount by deleting the vmp
entry from the list before it gets freed.

libglusterfsclient: Re-validate root inode on every path resolution

2009-09-24T08:19:20+00:00

If the root inode's is outdated, send a revalidate on it.
A revalidate on root inode also reduces the window in which an
op will fail over distribute because the layout of the root
directory did not  get constructed when we sent the lookup on
root in glusterfs_init. That can happen when not all children of a
distribute volume were up at the time of glusterfs_init.

performance/quick-read: access glusterfs_ctx from xlator instead of using glusterfs_get_ctx

2009-09-17T08:28:29+00:00

- since glusterfs_get_ctx gets the global context pointer, there can be
    problems in a multithreaded application running on libglusterfsclient
    doing multiple glusterfs_inits. Hence use context specific to the
    current xlator tree stored in each xlator object.
