* libglusterfs,mount/fuse: implement gidcache mechanism in fuse-bridgeBrian Foster2012-07-171-0/+181
This change genericizes the cache mechanism implemented in commit 8efd2845 into libglusterfs/src/gidcache.[ch] and adds fuse-bridge as a client. The cache mechanism is fundamentally equivalent, with some minor changes: - Change cache key from uid_t to uint64_t. - Modify the cache add logic to locate and use an entry with a matching ID, should it already exist. This addresses a bug in the existing mechanism where an expired entry supercedes a newly added entry in lookup, causing repeated adds and flushing of a cache bucket. The fuse group cache is disabled by default. It can be enabled via the 'gid-timeout' fuse-bridge translator option and accompanying mount option (i.e., '-o gid-timeout=1' for a 1s entry timeout).
