Pranith Kumar K 7ec3a8527f cluster/afr: Remove local from owners_list on failure of lock-acquisition 
When eager-lock lock acquisition fails because of say network failures, the
local is not being removed from owners_list, this leads to accumulation of
waiting frames and the application will hang because the waiting frames are
under the assumption that another transaction is in the process of acquiring
lock because owner-list is not empty. Handled this case as well in this patch.
Added asserts to make it easier to find these problems in future.

Gluster

Gluster is a software defined distributed storage that can scale to several petabytes. It provides interfaces for object, block and file storage.

Development

Contributions to gluster in the form of patches and new feature additions can be made by following steps outlined at Developers Guide.

Documentation

The Gluster documentation can be found at Gluster Docs.

Deployment

Quick instructions to build and install can be found in INSTALL file.

Testing

GlusterFS source contains some functional tests under tests/ directory. All these tests are run against every patch submitted for review. If you want your patch to be tested, please add a .t test file as part of your patch submission. You can also submit a patch to only add a .t file for the test case you are aware of.

To run these tests, on your test-machine, just run ./run-tests.sh. Don't run this on a machine where you have 'production' glusterfs is running, as it would blindly kill all gluster processes in each runs.

If you are sending a patch, and want to validate one or few specific tests, then run a single test by running the below command.

  bash# /bin/bash ${path_to_gluster}/tests/basic/rpc-coverage.t

You can also use prove tool if available in your machine, as follows.

  bash# prove -vmfe '/bin/bash' ${path_to_gluster}/tests/basic/rpc-coverage.t
