| | | | | | | | Here I am only refining the entry parsing code in order to clarify the exit conditions from the loop. There were a few workloads where this loop went infinite. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* libglusterfsclient: Revert and re-do readdir conformanceShehjar Tikoo2009-05-182-61/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit basically reverts the previous readdir conformance patch I sent a few days back. That commit had a completely retarded and broken way of maintaining per-directory dirent. It was broken for two reasons: 1. Creating a wrapper structure around the directory's fd_t only for storing a struct dirent is not clean enough. This commit takes a better approach by storing the dirent in fd_t context. This dirent is valid only if the fd_t refers to a directory. 2. That commit was made and tested under the assumption (..stupidity is a better word..) that only opendir call is used for opening a directory. That is not correct. Directories are also opened using the open syscall. The point is, glusterfs_open returns an fd_t and so did glusterfs_opendir. The previous patch actually changed opendir to return a new wrapper structure. That is fine, if we go by the POSIX definition of open and opendir because, they're both supposed to return different types, an int and a DIR*. However, in libglusterfsclient, all other code assumes that directory handles corresponding to DIR* and file descriptors corresponding to int types are the same type, resulting in use of the same locking and fd context addition/extraction code. So a directory opened using opendir returned a wrapper structure which went down into the libglusterfsclient stack where some function called a lock on the handle assuming it was an fd_t, since it is not and dereferencing of the supposed fd->inode->lock results in a seg fault. Obviously, this didnt show up till unfs3 used open() to open a directory and not opendir. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* booster: Supplement fstab option parsingShehjar Tikoo2009-05-181-6/+14
| | | | | | | | Previous fstab option parsing logic was completely retarded and did not handle all cases. This fixes the situation so we now work without any problems. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* client-protocol: Fix memory corruption in client_lookupRaghavendra G2009-05-161-13/+7
| | | | | | | | - memory corruption was due to new members being added between allocation of buffer for serializing xattr_req dictionary and dict_serialize of xattr_req. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* dict.c: Add dict_allocate_and_serializeRaghavendra G2009-05-162-0/+230
| | | | | | | | | - this procedure atomically allocates a buffer and serializes dict into it. - this procedure helps avoid memory corruptions due to race conditions where in new members are added into dict between allocating a buffer for serializing and actually serializing buffer into it.

* booster: Add fstab parsing supportShehjar Tikoo2009-05-084-59/+467
| | | | | | | | | | | | | This commit changes the booster.conf format from a simple custom format to that of the /etc/fstab.c See booster_mount(..) for the mount options supported/required for LD_PRELOADing booster. I'll write a small help doc soon. This commit also brings in fstab parsing code into libglusterfs because Darwin libc only supports reading the hardcoded /etc/fstab. Signed-off-by: Anand V.

| | | | | | | | | - sc_readlink wrongly returned strlen (link) + 1 when link was present in cache. - this fixes rt #828. Since fuse_readlink_cbk does link[op_ret] = '\0', there was a memory corruption. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* transport shortcut b/w client and serverAnand V. Avati2009-05-074-2/+131
| | | | | | This patch makes the server pass back the transport pointer of the client. If the UUID matches, the client makes the local transport 'shortcut' with the remote transport (pointer received from server) The shortcut simulates a socket queue. Instead of serialized messages going over the network and getting queued in the tcp socket queue, the messages get queued in a transport specific queue picked by a polling thread.

* libglusterfsclient: Improve readdir conformance on re-entrancyShehjar Tikoo2009-05-062-23/+63
| | | | | | | | | | | readdir is supposed to be non-re-entrant only with respect to the given dir stream, not the whole process. What that means is the static struct dirent that we maintain in libglusterfsclient should be per-directory handle and not process-wide. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* 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>
