* stat-prefetch: fix unsafe reference to @local in sp_lookup_cbkAnand Avati2009-12-011-1/+5
| | | | | | | | | | | | | stat-prefetch uses the main syscall frame for performing lookup on demand. this causes a potential reference to a freed local in sp_lookup_cbk after resuming the main syscall frame (which could have unwound and destroyed) Signed-off-by: Anand V.

| | | | | | | | | | | | | | | | lookup on same path if one is in progress. - If current lookup (2) does not wait for completion of the lookup (1) which is in progress, there can be a race condition where (2) completes ahead of (1) and resuming all the waiting operations in the queue. When (1) returns, the original operation (eg., stat, chmod etc) might've already unwound and hence the frame would've been destroyed.

* Changed rbthash_table_init() to take a mem-pool argument.Vijay Bellur2009-11-264-20/+66
| | | | | | | | | | | | | | | | | | | 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/stat-prefetch: don't free the cache in readdir if the offset is ↵Raghavendra G2009-11-241-5/+2
| | | | | | | | | | | | | | | | | | | | | | not the expected one. - cache creation is expensive operation. Also, cache will be freed in releasedir. Hence, just remove all entries from cache without freeing the cache. However this is not entirely true, since sp_cache_remove_entry frees the old table and reinitializes a new table if all entries are being removed. When rbtree based hash table provides an interface to remove all the entries, sp_cache_remove_entry should be modified not to destroy the table. - this patch also fixes a race condition wherein the cache being used in lookup getting freed in readdir if the offset is not equal to expected offset.

* performance/io-cache: change the hash function used for rbtree based hash table.Raghavendra G2009-10-292-12/+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.
