features/changelog: Don't modify 'pargfid' in 'resolve_pargfid_to_path'

2016-03-31T15:56:13+00:00

Backport of http://review.gluster.org/#/c/13845/

If 'changelog' is enabled and 'changelog.capture-del-path' option is on
it calls 'resolve_pargfid_to_path' which modifies 'pargfid' sent by
caller.  'changelog_unlink' calls this routine directly with
'loc->pargfid' resulting it being modified and point to root instead of
actual pargfid. This is a nasty bug and could cause the deletion of
entry on root directory instead on actual parent when 'loc->path' is
not present.  Hence this fix to make 'pargfid' a const pointer and
'resolve_pargfid' to work on copy of pargfid.

Glusterfind session creation enables these options by default to
capture deleted entry path in changelog.

Thanks Pranith for root causing this.

cluster/ec: Rebalance hangs during rename

2016-03-31T12:45:50+00:00

Problem:
During the rename of a particular file (ec
is holding blocking inodelk on the parent
directory), if the rename of another file
under the same directory comes. EC does not
release the lock and goes ahead and renames
the "new" file with the "already held lock".

That causes rebalance process to be blocked
on a lock which has been acquired by rename.

Solution:
While rename fop comes, ec takes blocking inodelk
on old and new parent of the file. Before releasing,
every lock held by ec, it waits for some "time" to
see if that lock can be reused by the next fop.
If within this "time" some other request comes,
it releases this lock based on condition
"lock count > 1"

To get this "lock count" for rename fop, we have
implemented "pl_rename" in feature/lock. Also,
on ec side, changed the condition to release the lock
based on the type of fop and old and new parent
directories.

server: send lookup on root inode when itable is created

2016-03-31T12:15:32+00:00

This is a backport of http://review.gluster.org/#/c/13837

 * xlators like quota, marker, posix_acl can cause problems
   if inode-ctx are not created.
   sometime these xlarors may not get lookup on root inode
   with below cases
   1) client may not send lookup on root inode (like NSR leader)
   2) if the xlators on one of the bricks are not up,
      and client sending lookup during this time: brick
      can miss the lookup
   It is always better to make sure that there is one lookup
   on root. So send a first lookup when the inode table is created

 * When sending lookup on root, new inode is created, we need to
   use itable->root instead

libglusterfs: open cmd_history log file with O_APPEND and O_WRONLY

2016-03-31T07:53:44+00:00

Commit 8fdfa0c introduced a fix to ensure cmd_history file is log rotated
properly. However with this fix fdopen() is called with mode "a" on a fd which
was not opened with O_WRONLY & O_APPEND resulting into a fdopen() failure.

Fix is to open cmd_history.log file with O_CREATE|O_WRONLY|O_APPEND mode

cluster/afr: Choose local child as source if possible

2016-03-31T06:30:54+00:00

It is better to choose local brick as source if possible to prevent
over the wire read thus saving on bandwidth. Also changed code to not
attempt data-heal if 'source' is selected as arbiter.

tools/glusterfind: Handling Unicode file names

2016-03-31T05:13:36+00:00

Unicode filenames handled cleanly with this patch. Changelog
files and output files are opened with utf-8 encoding using codecs.open.

urllib.quote_plus and unquote_plus will not handle Unicode so, encode
Unicode to 8-bit string version before calling unquote. urllib.quote_plus
requires 8-bit string itself so do not decode to Unicode if we need to use
quote_plus(when --no-encode=false). Decode to unicode in --no-encode is set.
