BUG: 361 (GlusterFS 3.0 should work on Mac OS/X)
URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=361

fixes to compile on MacOSX (no fuse client)

2009-12-02T03:48:41+00:00

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 "

Changed rbthash_table_init() to take a mem-pool argument.

2009-11-26T12:32:25+00:00

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.

BUG: 335 (Io-cache optimization)
URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=335

performance/io-cache: change the hash function used for rbtree based hash table.

2009-10-29T17:07:49+00:00

- 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.
