added log message when server fails to send the reply frame

2009-08-17T21:38:10+00:00

As of now, if a frame submit fails on server, there are no logs,
and clients will have missing frames (which leads to 'hangs').
Supporting situation like this very tricky without proper log
messages. As a step to make our log message lean and meaningful,
this log is important.

server-lookup: added path info from header to log message

2009-08-05T00:27:33+00:00

in the previous commit, the path info was removed to prevent the
segfault, which instead could have been provided from request
header directly. More specific information is required for debugging,
and hence adding the path log.

logging related bug fix in server_lookup()

2009-08-04T23:47:48+00:00

When 'dict_unserialize' failed, the log message was trying to
print 'state->loc.path' and 'state->ino', which gets filled in
later stages in flow. Caused segmentation fault when there was
a failure.

server-protocol: fix in server-loc-fill()

2009-07-28T16:42:41+00:00

to continue with 'hashed' inode, even if inode_path() on the inode
fails. This will is needed for few lock operations, to unlock the
lock held on inode. (ie, it fixes 'rm -rf *' hang issue, seen from
multiple clients).

protocol/server: add checks for updatation of loc->parent in entrylk() or inodelk().

2009-07-27T18:33:56+00:00

entrylk() and inodelk() should try to update loc->parent only if parent is not-NULL.
because it is not an error to have loc->parent == NULL for entrylk() and inodelk()
operations.

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.
