* libglusterfsclient: Fix large directory reading bugShehjar Tikoo2009-05-061-3/+16
| | | | | | | | | | | | | | As of now, we use 1024 bytes as the buffer for reading directory entries. If a directory as many files, then its possible that it does not fit into this buffer, thereby requiring more than one call to readdir. Now suppose the last bunch of directories fit more or less exactly int the 1024 byte buffer. If this happens, the offset extracted by the current logic(in libgf_client_readdir) never gets updated beyond the first entry in this last block, because the last block's first entry always remains same. This explanation is convoluted, I know, but I too found out the hard way. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* libglusterfsclient: Conform'ify glusterfs_readdirShehjar Tikoo2009-05-052-22/+31
| | | | | | | | | | | This commit does two things: 1. Changes glusterfs_readdir prototype to conform to the POSIX readdir(). 2. Uses a 1024-byte value instead of sizeof(struct dirent) for the @size for libgf_client_readdir. This allows even larger names to fit into a single readdir request to the server.

* libglusterfsclient: Make stat resolve all symlinksShehjar Tikoo2009-05-051-11/+10
| | | | | | | | We want to resolve even nested symlinks when calling stat, therefore, we need to depend on realpath-like functionality and not just a readlink. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* libglusterfsclient: Fix realpath operationShehjar Tikoo2009-05-051-23/+25
| | | | | | | | | | | | | | | This commit does two things: 1. Ensures we go on to traverse nested symlinks by calling realpath recursively on the symlink. 2. Makes glusterfs_realpath, a VMP-based operation, return a resolved /real path that actually has the VMP pre-fixed to the resolved path. If this is not done, we'll be returning a path that is valid only within the glusterfs context, i.e. the path will point to a real file/dir only if a glusterfs handle identifies which glusterfs context the file is in.

* libglusterfsclient: Guard against un-inited VMP searchesShehjar Tikoo2009-05-051-0/+6
| | | | | | | | | | | On my system, an selinux module gets inited before booster even though the FS calls from the selinux module get routed through our LD_PRELOAD'ed wrappers. In this scenario, the VMP list is un-inited, resulting in a seg-fault if it is dereferenced. The list_empty check does not help because the pointers in the list have non-NULL values.

| | | | | | | | | | | Some of the functions have also been moved within the header to reflect the order in which users will read through and try to understand how to use the lib. For eg. the init, mount and umount functions have been moved to the beginning to clarify how to start by init and de-initing. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* libglusterfsclient: Fix stat cache bugShehjar Tikoo2009-04-211-5/+12
| | | | | | | | | | | | | The way stat cache gets updated was not consistent across all syscalls. Consequently, I was running into a bug that returned a 0 st_ino. The fix actually resides in the hunk that changes the lines in libgf_client_lookup but similar changes were also required in other users of stat cache. This commit fixes the bug and also cleans up the way stat cache is updated. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* libglusterfsclient: Add virtual mount point supportShehjar Tikoo2009-04-213-0/+178
| | | | | | | | | | | | | | | | | | | | | One part of the glusterfsclient library requires users to use a handle to address a particular glusterfs context. This can become cumbersome for applications that need to use multiple such context. For such applications, we make it easy by letting them define virtual mount points(VMPs), which are just paths that identify a particular glusterfs context. This is done through a new glusterfs_mount(..) interface. Subsequenly, any path based operations, that pre-pend a VMP before the files and directories inside the glusterfsd export, get internally routed to the correct glusterfs context. This helps users do away with the need to maintain their own path-to-glusterfs_handle_t mapping. The old handle-based interface still exists for whoever wishes to use it. Signed-off-by: Anand V.
