* Make swift's expirer compatible with gluster-swiftPrashanth Pai2016-04-201-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | Swift's object expirer in kilo series was incompatible with gluster-swift. This change does the following: * Optimizes crawl in account and container server for listing requests for containers and tracker objects in gsexpiring volume. * Enables container server to delete tracker objects from gsexpiring volume. Swift's expirer sends request directly to container server to remove tracker object entry. * delete_tracker_object() is now a common utility function that is invoked from container server and gluster-swift's object expirer. * Run functional test to be run against both swift's object expirer and gluster-swift's object expirer Change-Id: Ib5b7f7f08fe7dda574f6dd80be2f38bdfaee32bc Signed-off-by: Prashanth Pai <ppai@redhat.com> Reviewed-on: http://review.gluster.org/14038 Reviewed-by: Thiago da Silva <thiago@redhat.com> Tested-by: Thiago da Silva <thiago@redhat.com>
* Enhance object expirationPrashanth Pai2016-04-151-13/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change re-introduces object expiration feature with some internal differences from earlier implementation such as: * Creation of zero-byte tracker object is performed directly on the mount point. Earlier HTTP request was sent to object server for the same. This incurred overhead of metadata creation for these zero-byte files which isn't necessarry as all required information is encoded in the path itself. * Crawling of zero-byte tracker objects is done by the object expirer daemon itself and not container server. * Deletion of tracker object is performed by the object expiration daemon directly on mount point. Deletion of actual data object is not carried out by object expiration daemon directly. The object expirer sends a DELETE request to object server which deletes the actual object. This behaviour is not changed. There is no change in behaviour in comparison with older implementation. This is asserted by re-enabling existing functional tests without any changes.

* Don't fetch metadata for plain container listingPrashanth Pai2016-04-041-3/+3
| | | | | | | | | | | | | | | | | Fetch metadata (xattr) for containers in an account ONLY when the client asks for it (using content-type indicating JSON or XML response). This avoids a lot of unnecessarry stat() and getxattr() calls whose results would anyways be unused. The performance gain is obvious in this case. This change is restricted to container listing. The same can be extended to object listing as well (will be sent as a separate change) Change-Id: Ibff1c5a90519f11053c0b651d8ea3385dda43a2f Signed-off-by: Prashanth Pai <ppai@redhat.com> Reviewed-on: http://review.gluster.org/13497 Reviewed-by: Thiago da Silva <thiago@redhat.com> Tested-by: Thiago da Silva <thiago@redhat.com>

| | | | | | | | | | | | | | | | This change ports most of swiftonfile object server fixes and changes into gluster-swift. Storage policy as a feature is not usable here (it doesn't make sense). The hacky way of creating zero byte tracker objects for object expiration has not been ported to this release due to scalability issues and the need to have a separate volume.

* Rebase to lastest OpenStack Swift DiskFile APIPeter Portante2013-10-291-45/+17
| | | | | | | | | | | | | | | | | | | | As of October 28th, 2013, we rebase to OpenStack Swift master (commit 4bfe674) to pick up the lastest officially supported DiskFile API changes. We use a snapshot of OpenStack Swift stored in the gluster-swift launchpad downloads area so that we can deliberately rebase at our own pace. With this refactoring, all the code for handling I/O is wholly contained in the swift tree for object operations. This will allow us to use a different fs_utils implementation in the future (for example, one based on a yet-to-be-implemented python bindings over libgfapi). This also means the "Fake_file" class has been removed entirely.

| | | | | | | | | | | | | | | | | It was painfully slow to gather a list of all the files in a directory tree when there were as many directories as files, since we also stat'd all of the directories as well.

So we have removed the memcache support entirely, and removed the stat of the directories as a result. See BZ 911448 (https://bugzilla.redhat.com/show_bug.cgi?id=911448).

We ported a set of test from OpenStack Swift's test/unit/commont/test_db.py, the testAccountBroker and testContainerBroker, but because of the divergent nature of the current attempt UFO (Unified File and Object) implementation, it was not possible to use the interface calls directly. Instead, we are using these tests to make sure most of the code paths are exercised, and to define much of the expected behavior. Further refactoring, unit tests and functional test work will help us bring the code base and these tests closer to the originals in upstream OpenStack Swift (as of Havana).
