* glusterfs: discard (hole punch) supportBrian Foster2013-06-131-2/+7
| | | | | | | | | | | | | | | | Add support for the DISCARD file operation. Discard punches a hole in a file in the provided range. Block de-allocation is implemented via fallocate() (as requested via fuse and passed on to the brick fs) but a separate fop is created within gluster to emphasize the fact that discard changes file data (the discarded region is replaced with zeroes) and must invalidate caches where appropriate.

* gluster: add fallocate fop supportBrian Foster2013-06-131-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement support for the fallocate file operation. fallocate allocates blocks for a particular inode such that future writes to the associated region of the file are guaranteed not to fail with ENOSPC. This patch adds fallocate support to the following areas: - libglusterfs - mount/fuse - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi BUG: 949242 Change-Id: Ice8e61351f9d6115c5df68768bc844abbf0ce8bd Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-on: http://review.gluster.org/4969 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>

| | | | | | | | | | | | | | This brings us back to functional parity with the C example, and also makes things more "Pythonic" (e.g. methods on Volume/File objects instead of bare functions).

* glfsxmp: libgfapi based exampleAnand Avati2012-07-185-0/+97
This is an example application which uses libgfapi. It is a complete autotools based build system which demonstrates the required changes in configure.ac, Makefile.am etc to successfuly detect for and build an application against libgfapi. There are two approaches to building a libgfapi based application: 1. In the presence of pkg-config in your build system. This is the recommended approach which is also used in this example. For this approach to work, you need to build glusterfs by passing --pkgconfigdir=/usr/lib64/pkgconfig (or the appropriate directory) in your distro. This already happens if you build RPMs with the glusterfs.spec provided in glusterfs.git. You will also need to install glusterfs-api RPM. 2. In the absence of pkg-config in your build system. Make sure your LDFLAGS includes -L/path/to/lib where libgfapi.so is installed and -I/path/to/include/glusterfs where the 'api' directory Change-Id: Ic4eab2df002d7e8d20593a03e643859423048848 BUG: 839950 Signed-off-by: Anand Avati <avati@redhat.com> Reviewed-on: http://review.gluster.com/3666 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Amar Tumballi <amarts@redhat.com>
