* Fix double close issue in diskfileLuis Pabon2013-11-221-6/+10
| | | | | | | | | | | | | The DiskWriter was closing the file descriptor when it finished writing but initializing it to None. Therefore, the DiskFile context manager would then try to close it also.

* Log only non-ENOENT errors in diskfileLuis Pabon2013-11-211-2/+3
| | | | | | | | | | | | | | | | | | DiskFile.open() gets called for every PUT. The expected sideeffect is that if the file exists, the metadata in the object will be populated. DiskFile.open() was logging any errors it detected while trying to open() the file. Issue is that when we PUT a new file, there is no entry, and open() will return an error. The was incorrectly logging each one of these errors.

* fix metadata overwrite during a post requestThiago da Silva2013-11-141-3/+37
| | | | | | | | | | | | | During a post request, the object-server is ovewriting the existing object metadata. This fix prevents the overwrite of the system metadata while it allows for the user to add/remove user metadata Change-Id: Ic62cd064589b625ee425a9934be8766650622c13 Signed-off-by: Thiago da Silva <thiago@redhat.com> Reviewed-on: http://review.gluster.org/6254 Reviewed-by: Luis Pabon <lpabon@redhat.com> Tested-by: Luis Pabon <lpabon@redhat.com>
* Improve logging and raising DiskFileNoSpacePrashanth Pai2013-11-141-2/+3
| | | | | | | | | | | | | | | | | | | | | | | This commit only improves logging whenever ENOSPC (No space on disk) or EDQUOT (Quota limit exceeded) is returned by glusterfs Also, added methods to: - get filename from file descriptor - log with rate limit Caveat: Although raising DiskFileNoSpace results in object-server returning HTTPInsufficientStorage[507] correctly, the swift proxy-server invokes "best_response" method that returns [503] to the user. When write-behind translator is turned on in glusterfs, it may set errno to EIO instead of ENOSPC/EDQUOT.

* Try to ensure we'll have a truly random postfixPeter Portante2013-08-281-3/+14
| | | | | | | | | | | | | | | While it is very improbable, it seemed fairly straight forward to add a small bit of code to ensure the temporary file name is random and won't clash with another host, pid or thread potentially working on the same object.

* Fix infinite loop for temp file renames on ENOENTPeter Portante2013-08-281-41/+45
| | | | | | | | | | | | | | | | | | | | | For whatever reason, it appears that GlusterFS, or perhaps FUSE can continuously return ENOENT on a rename system call even when we have double checked that there is no reason to do so. That is a bug for that sub system. However, our response to that bug can result in an infinite loop, which is bad. This code reduces that to 10 attempts. In addition, we restructed the open retry loop to match, providing module constants for the upper bounds of both retry loops.

* Add DiskDir unit test skeleton and pep8 filterPeter Portante2013-05-241-2/+2
| | | | | | | | | | | | | | | | | The new DiskDir unit test skeleton is quite incomplete, but gets the DiskDir module on the board for modules covered, explicitly exposing the fact that we need to get test coverage. This is a first step. At the same time, we also update all the modules we have applying the fix for pep8 errors now run under tox. We can then add a Jenkins pre-commit job to fail on pep8 errors. This brings our code to parity with what they are doing in OpenStack Swift.
