* common-utils: introduce new macro GF_VALIDATE_OR_GOTO_WITH_ERRORRaghavendra G2009-09-081-0/+9

* performance/stat-prefetch: introduce sp_fd_ctx_t to hold context of fdsRaghavendra G2009-09-082-11/+144
| | | | | | | | | | | | | | - we need following extra members along with cache 1. basename of path on which fd is opened. This is necessary to search for cached entry in fd based fops. 2. inode corresponding to dirname of path on which fd is opened. This is necessary to get cache where entry corresponding to file on which fd is opened. Signed-off-by: Anand V.

| | | | | | | | | | | - stat-prefetch aims to optimize operations like 'ls -l' where a readdir is immediately followed by stat calls on each of the directory entry read.

* libglusterfsclient: Compare compcount with path not maxentryShehjar Tikoo2009-09-021-0/+1
| | | | | | | | | | | | | | When searching for an exact entry we need to compare the component counts in the candidate VMP and the count in the path being searched. This is opposite to the current situation where we compare the component count in VMP and the component count in maxentry, which will always be same. Signed-off-by: Anand V.

* | libglusterfsclient: Sync access to VMP list on new entry additionShehjar Tikoo2009-08-171-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some weeks back, I'd separated the big lock into vmplock and mountlock. See commit 304e4274ca9b0339539581c5413e3339078c1182 in mainline. At that time, we did not have a solution to the problem of when to init the vmplist in a thread-safe manner, since there was no lock to protect the vmplock specifically, and that when libgf_vmp_map_ghandle was called inside glusterfs_mount so the "lock" was already being held. Now that we have separate mount and vmp locks, the accesses can be synced correctly. Signed-off-by: Anand V.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Till now, we've been doing a character by character comparison between a given path and the VMP, to search for the glusterfs handle for the given path. This does not work for all cases and has been a known bug. This commit changes the byte-by-byte comparison into a more accurate component based comparison to fix search failures.

* protocol/client: fixed registration of saved_fdsAnand Avati2009-08-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | In client_open_cbk, client_opendir_cbk the list_add_tail macros were invoked with wrong ordered arguments, causing the existing registered fd list to get unlinked from the saved_fds list. The effects of this is far fetched - when transport disconnects, open fds are no more marked bad as they are not reachable from the saved_fds list. After reconnection, resumed access on this fd causes reference to invalid fds on the server. It could appear in the form of 'unresolved fd' error, readdir happening on a file fd, files reading from other files, etc. Signed-off-by: Anand V.
