From 59ff893d11844eb52453ce4f7f098df05fcde174 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Mon, 16 Jul 2012 13:51:09 -0400 Subject: libglusterfs,mount/fuse: implement gidcache mechanism in fuse-bridge 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).
