* performance/stat-prefetch: lookup the path in open if it is not already ↵Raghavendra G2009-10-091-9/+77
| | | | | | | | | looked up. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 221 (stat prefetch implementation) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=221
* performance/stat-prefetch: implement procedure sp_process_inode_ctx.Raghavendra G2009-10-091-0/+93
| | | | | | | | | | | | | - this procedure processes inode_ctx to make decisions like whether the current procedure can continue (i.e., inode is already looked up), or the procedure has to initiate/wait for lookup on the path. It also sets up the frame->local and adds the stub corresponding to current fop if needed. Signed-off-by: Anand V.

* performance/stat-prefetch: use op_errno instead of errno to store error code.Raghavendra G2009-10-091-109/+191

* performance/stat-prefetch: Add support code to implement lookup-behind.Raghavendra G2009-10-091-55/+184
| | | | | | | | | | | | | - change sp_lookup and sp_lookup_cbk to support sending lookups when needed. lookups might need to be sent in fops like open, chmod, chown etc which operate on a path, since the actual lookup sent to stat-prefetch by its parent xlators is not propagated down the xlator tree if the path is cached.

* performance/stat-prefetch: remove lookup-behind in sp_lookup.Raghavendra G2009-10-091-60/+8
| | | | | | | | | | | | - lookup-behind should be done on-demand basis, in fops like open instead of in sp_lookup itself. This would reduce network traffic between client and server related to lookup, if the only use of lookup was to fetch stat structure. Signed-off-by: Anand V.

* performance/stat-prefetch: optimizations to sp_lookup.Raghavendra G2009-10-091-1/+12
| | | | | | | | | | | - if stat cache cannot be found for a path in its parent inode and the path is a directory, we can get the cache from the inode corresponding to path and look for "." in that cache.

* performance/stat-prefetch: change behaviour of sp_lookup when xattr_req is ↵Raghavendra G2009-10-091-8/+28
| | | | | | | | | | | | | not NULL. - if the xattr_req is empty (fuse just creates an empty dictionary and sends along lookup) we can still use the cache prefetched during readdir, since we need not fill the reply dictionary.

* performance/stat-prefetch: change the cache to use rbtree based hashtable ↵Raghavendra G2009-10-091-34/+42
| | | | | | | | | instead of list for caching dentries. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 221 (stat prefetch implementation) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=221
* performance/stat-prefetch: fix memory leaksRaghavendra G2009-10-091-16/+37
| | | | | | | | | | | | | | | - sp_cache_get_inode uses fd_lookup which internally increases the refcount of fd by 1. This needs to be unrefed once we get the cache. - for directories, stat is stored in the inode context in sp_lookup_cbk. but, while doing so, no check was being done for the presence of context in inode, resulting in leak of memory equal to sizeof (struct stat) when multiple lookups happened on the directory. - path constructed in sp_readdir was not freed.
