* libglusterfs: Add empty and NULL dirents list checksShehjar Tikoo2009-06-082-0/+12
| | | | | | | | | | | | These checks are needed in case a higher layer intends to delink the dirent list and passes a NULL pointer to fop_readdir_cbk_stub for the entries parameter. Consequently, the gf_dirent_free must guard against an empty list because the stub that is passed to it mgiht have an empty dirent list. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

* booster: Move fstab parsing into booster from libglusterfsShehjar Tikoo2009-05-203-393/+2
| | | | | | | | | | | This is another attempt at fixing build problems on Solaris. I am told that booster build is disabled on Solaris and I know that it is disabled on Mac OS X also. Getting it to work on both these systems is now on my TODO list, mainly because on both these systems, we can have a glusterfs client running without requiring FUSE. Signed-off-by: Anand V.

* mem-pool: Restructure mem-pool behaviourShehjar Tikoo2009-05-192-31/+55
| | | | | | | | | | | | | | | | | | This commit changes mem-pool behaviour to return a directly usable address by performing the required adjustment on the address being returned. This is different from the previous behaviour where we're trying to fit into the requested size, the list_head*2 also. This is not efficient enough in terms of space but hopefully works better than not having any mem-pool at all. Besides, I am not comfortable with mem-pool meta-data and caller-useable memory area being the same because of the potential for mem-pool's data structure corruption. PS: Please do read the comments in the code for more info during review. 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 Tikoo2009-05-083-2/+393
| | | | | | | | | | | | | 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.

* transport shortcut b/w client and serverAnand V. Avati2009-05-072-2/+118
| | | | | | 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: Use macros for argument checksShehjar Tikoo2009-04-171-0/+10
| | | | | | | | | | Having those if {} blocks to check for argument validity hurts the eye so this patch replaces those checks with macros. One macro already exists in libglusterfs.
