gfapi.py: support dynamic loading of versioned libraries

2013-10-02T20:04:03+00:00

Currently gfapi.py only loads libraries by filename ending in ".so".  On
an installed system without development packages, the .so filenames
are not available. ctypes.util.find_library() can be used to detect the
files dynamically.

In addition to this, also fixing some minor indention errors and package
the library into the Python site-packages path. Python applications and
libraries can now access libgfapi through 'from glusterfs import gfapi'.

glusterfs: discard (hole punch) support

2013-06-13T21:37:43+00:00

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 support

2013-06-13T21:37:21+00:00

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

api: update Python wrapper

2012-12-20T03:16:51+00:00

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 example

2012-07-18T19:12:25+00:00

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
