* storage/posix: Make the janitor sleep duration configurable.v3.0.1rc2Vikas Gorur2010-01-212-12/+35

* storage/posix: Hand off calling close() and closedir() to the janitor thread.Vikas Gorur2010-01-192-33/+81
| | | | | | | | | | | | Let the janitor thread handle calling close() and closedir() on fd's and DIR * when posix_release is called. This avoids blocking the main server loop due to close().

* storage/posix: Added janitor thread.Vikas Gorur2009-12-022-1/+119
| | | | | | | | | | | | | | | | | | The janitor thread deletes all files and directories in the "/" GF_REPLICATE_TRASH_DIR directory. This directory is used by replicate self-heal to dump files and directories it deletes. This is needed because letting replicate walk the directory tree and delete a directory and all its children is too racy. Instead, replicate self-heal only does an atomic rename(), and the janitor thread takes care of actually deleting them. Signed-off-by: Vikas Gorur <vikas@gluster.com> Signed-off-by: Anand V.

* storage/posix: handle dentries from different mount points in readdirRaghavendra G2009-09-081-34/+51
| | | | | | | | | | | | | | | | | - If posix translator is configured to have export directories to span accross different mount points, inode number is transformed in the dentry returned. Otherwise, the entry is not added to list of entries returned in readdir callback. - storage/posix returns ENOENT if the file is on different mount point other than that of exported directory and is not configured for export directory spanning across multiple mountpoints during lookup. But, since stat-prefetch shortcuts lookup calls, its necessary that readdir return only valid dentries. Signed-off-by: Anand V.
