* core, client, server: Support auxiliary group idsShehjar Tikoo2009-12-032-0/+20
| | | | | | | | | | | | | | | | | | | Support for auxiliary group ids is needed for transmission of more than one group id right through the xlator tree so that posix can use these group ids to perform in-house permission tests. The in-house permission checks are needed so that we do not have to depend on non-POSIX calls like setfs[ug]id for changing the user for each fop. The setfs[ug]id are also limited since they do not allow setting multiple group id as required for operation with NFS, which sends us all the group ids for a process issuing file system requests.

* storage/posix: Added janitor thread.Vikas Gorur2009-12-021-0/+2
| | | | | | | | | | | | | | | | | | The janitor thread deletes all files and directories in the "/" GF_REPLICATE_TRASH_DIR directory. This directory is used by replicate self-heal to dump files and directories it deletes. This is needed because letting replicate walk the directory tree and delete a directory and all its children is too racy. Instead, replicate self-heal only does an atomic rename(), and the janitor thread takes care of actually deleting them. Signed-off-by: Vikas Gorur <vikas@gluster.com> Signed-off-by: Anand V.

* Changed rbthash_table_init() to take a mem-pool argument.Vijay Bellur2009-11-262-11/+49
| | | | | | | | | | | | | | | | | | | Changes in libglusterfs/rbthash: rbthash_table_init() now takes a mem-pool argument. The mem-pool argument would be mutually exclusive to expected_entries. If expected_entries is provided, mem-pool would be ignored and vice-versa. Changes in io-cache: 1) Moved rbthash creation to readv. 2) rbthash makes use of 1 rbt instead of 4096 3) A global mem-pool is being used in place of a mem-pool per rbt.

* performance/io-cache: change the hash function used for rbtree based hash table.Raghavendra G2009-10-292-0/+16
| | | | | | | | | | | | | | | - the earlier hash function does not distribute pages uniformly for offsets that fit into 32 bits. The reason is that the hash function just xors the contents of the key 4 bytes at a time with the current value of hash. Hence for keys that fit into 32 bits, the hash will be the key itself. Since we are using the rounded_offset (which is a multiple of 128KB) as the key, the key will be exactly divisible by the number of buckets configured (4096) resolving all the pages into the first bucket.
