* gfapi: object handle based API extensionsR.Shyamsundar2013-10-111-5/+1359
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is an ongoing effort to integrate NFS Ganesha ( https://github.com/nfs-ganesha/nfs-ganesha/wiki ) with GlusterFS as one of the file system back ends. Towards this we need extensions to gfapi that can handle object based operations. Meaning, instead of using full paths or relative paths from cwd, it is required that we can work with APIs, like the *at POSIX variants, to be able to create, lookup, open etc. files and directories. Hence the objects are the files or directories themselves and we give out handles to these objects that can be used for further operations. This code drop is an initial implementation of the proposed APIs. The new APIs are implemented as glfs_h_XXX variants in the file glfs-handleops.c to mirror glfs-fops.c style. The code leverages holding onto inode references and doling these out as opaque/cookie type objects to the callers, to enable them to be used as handles in other operations. An fd based approach was considered, but due to the extra footprint that the fd structure and its counterparts would incur, this was dropped to take the approach of holding inode references themselves. Tested by extending glfsxmp.c to invoke and exercise the added APIs, and further tested with a reference integration of the same as an FSAL with NFS Ganesha.

* gfapi.py: support dynamic loading of versioned librariesNiels de Vos2013-10-023-10/+44
| | | | | | | | | | | | | | | | | | Currently gfapi.py only loads libraries by filename ending in ".so". On an installed system without development packages, the <lib>.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) 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.

* 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>
