| | | | | | | | | | | | | | | * Openstack swift uses the /var/run/swift directory to store the pid files for all the servers. * Also, added a script that would unmount the gluster client on a volume stop.

* object-storage: yield during directory tree walksPeter Portante2013-02-041-10/+15
| | | | | | | | | | | | | | | | | | | Have the co-routine (greenlet) yield during long running directory tree walks to avoid starving out other greenlets that might be available to run. A directory walk involves statting every file in the tree to get it size. For large numbers of files, this can get expensive. So we yield after every stat call, and after processing every directory.

| | | | | | | | | | | | | | | | | | | Only open a file when the caller of the constructor indicates that it expects to have a file pointer to access in the "fp" field. Found by Junaid during review http://review.gluster.org/4284, Patch set 6. We also bump the version number to mark a line in the set of changes we want to perform a mini release with to double check for performance regressions.

* object-storage: don't sort object list, not req'dPeter Portante2012-12-171-3/+0
| | | | | | | | | | | | | | The REST API for listing objects in a container does not require that the list of objects be sorted (the API for listing containers in an account does require it). Since we can have thousands and thousands of objects in a container, don't sort them when it is not required.

* object-storage: Initial unittest of DiskFile classPeter Portante2012-12-172-49/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we had this ahead of time, we could have avoided the errors that were encountered leading to the fix-account-mapping fix (see http://review.gluster.org/4222). This represents 100% coverage of the DiskFile module, but the coverage report says otherwise, unfortunately. That is because the put() method invokes eventlets during the test run, and coverage is not able to accurately track the coverage lines properly. If one comments out the "tpool.execute()" line in DiskFile.put() the coverage report then reports 100% for the DiskFile module. Additionally, we changed DiskFile.put() in four ways that should not change its behavior: 1. Comments were added to explain various code paths and mark potential issues / fixes 2. It no longer returns a boolean value, matching the behavior of swift.obj.server.DiskFile.put() 3. It no longer logs a message when it detects a directory that already exists, instead is raises an exception We believe this is okay because we cannot find a code path that would lead to his condition. As a result, it makes it easier to test all the code paths in that routine. 4. It no longer logs a message when create_dir_object() fails, since create_dir_object() raises an exception on failure only We also modified create_dir_object() to not return a boolean as a result of the above behavior. Note that by implementing these tests up to this point we found three code paths that would have failed if encountered due to missing imports. We also made changes to the DiskFile module to make it a bit easier to test, also eliminating an extra stat system call when deleting directory objects.

* object-storage: Use "-dev" in the version stringPeter Portante2012-12-101-1/+1
| | | | | | | | | | | | | | | | | | | Currently, we have not solved the account mapping story entirely (we don't have a way to support more than one account to gluster volume in the mapping). As such, do not declare this as the final version. Also update the default RHS 2.0 spec file to "-3" for the release number to refer to the fact that we now have a working account mapping (see http://review.gluster.org/4222).

* object-storage: fix account mappingPeter Portante2012-12-064-10/+8
| | | | | | | | | | | | | | | | | | | | | Fix the account mapping so that we always use what is provided by the request. With this fix, "/mnt/gluster-object/AUTH_ufo0" directory hierachies won't be created. But this fix does not restore the one-to-one account to gluster volume name mapping. When the user runs the /usr/bin/gluster-swift-gen-builders script, it still only allows one cluster volume, and that is the only volume that is used. So the account names are effectively ignored. A future set of changes will address that problem.
