allocate extra bytes (for \0) when calling realloc

2011-08-18T04:01:38+00:00

We use strcat to concat pathinfo strings. strcat appends a \0 at
the end. Therefore allocate extra bytes for the same to avoid
asserts being hit during gf_free call

cluster/dht: clear local->cached_subvol when switching to do_fresh_lookup

2011-08-06T12:49:22+00:00

The presence of local->cached_subvol makes dht_lookup_everywhere_done behave
as though it was a lookup on a file where linkfile needs to be recreated. In
a fresh lookup, local->cached_subvol should be NULL.

DHT rename: Recreate linkfile after unlink

2011-08-04T04:57:27+00:00

This is done, so that there is no gfid mismatch. Unlink the older
linkfile if it exists, and recreate it with the correct gfid.

Also removed unused rename related code.

cluster/distribute: while fixing layout, consider ENOSPC errors

2011-07-27T06:48:17+00:00

in case of layout 'creation', layout->err == ENOSPC should be ignored
where as, while layout 'fixing' we should consider what was already
present in the layout.

cluster/dht: dht_rename() - handle GFID situations

2011-07-25T16:22:30+00:00

In the pre-GFID era, the linkfile of the destination file could be reused
the linkfile for the renamed file when dst_cached == src_cached.
This patch handles this situation and reverts the previous (wrong) fix.

distribute: bring in feature to do rebalance from inside

2011-07-14T08:01:44+00:00

do the 'rebalance' on a file with 'setxattr()' with
'distribute.migrate-data' key. the valid 'value' is "force" or
anything else.

current implementation of 'rebalance' is same as 'glusterd-rebalance',
and hence comes with limitation of not rebalancing hardlinks, non-regular
files, and files with open-fds.
