* fixes to compile on MacOSX (no fuse client)Amar Tumballi2009-12-011-11/+1
| | | | | | | | | | | | | | | These changes are required to make GlusterFS compile on MacOSX (10.5). Currently glusterfs server component alone will work over Mac, and it has to be built with following options to ./configure. "bash$ ./configure --disable-fuse-client --disable-fusermount " Signed-off-by: Amar Tumballi <amar@gluster.com> Signed-off-by: Anand V.

* Changed rbthash_table_init() to take a mem-pool argument.Vijay Bellur2009-11-261-10/+0
| | | | | | | | | | | | | | | | | | | 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 G2009-10-291-7/+5
| | | | | | | | | | | | | | | - 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.

* libglusterfs/rbtree: change rbthash_init_table to take no of expected ↵Raghavendra G2009-10-281-4/+9
| | | | | | | | | | | | | | entries in the hash table as argument. - the expected number of entries is used to create the memory pool of the hash table. Having constant macro for this purpose is not suitable since different users of rbtree based hash table store different number of entries in the table. Signed-off-by: Anand V.

* performance/io-cache: fix double free.Raghavendra G2009-10-281-1/+1
| | | | | | | | | | | - the destroyer function passed to rbthash_table_init is used to free the data. The data being inserted is page and it is destroyed in ioc_page_destroy. Hence no destroyer function needs to be passed to rbthash_table_init. Signed-off-by: Anand V.
