Fix validation of marker dir objects

2016-09-12T17:14:52+00:00

For marker directory objects, validate_object() always returned False.
This was because st_size from stat was being compared to Content-Length
stored in metadata. Unlike files, for directories st_size is always
4096. Hence the comparison would always be '4096 == 0' which would
fail.

This patch makes the following changes:
* Do size comparison of st_size and Content-Length only for files.
* Get rid of _is_dir everywhere. This will simplify things.

Don't attempt unlink on a non-existing object

2016-08-10T18:37:28+00:00

Problem:
getxattr() and unlink() were being called on an object path which was
already determined to be non-existent. This resulted in both these
syscalls always failing with ENOENT when client issues DELETE request on
an object that does not exist.

A request to DELETE an object will incur the following DiskFile API
calls in sequence:
    disk_file.read_metadata()
    disk_file.delete()

The above mentioned problem manifests because Swift code invokes
disk_file.delete() even when disk_file.read_metadata() has raised
DiskFileNotExist.

Fix:
During disk_file.read_metadata(), make a note that the file does not
exist. When disk_file.delete() is called, do not proceed with object
deletion.

Don't (f)chown when it has no effect

2016-05-04T14:21:14+00:00

For (f)chown calls which can change both UID and GID at once, -1 is
reserved as a sentinel value to indicate "omitted argument" or "do
not change". This makes sense when one of the args to (f)chown is -1.
When both uid and gid args are -1, it doesn't make sense to call
(f)chown as neither is going to be changed.

Further, as of today, diskfile doesn't get the information (uid and
gid) of the authenticated user from auth middleware. Retained the
calls in code for future when such functionality might be added.

Open object only if it's going to be read

2016-05-03T19:47:05+00:00

Open()ing an object is necessarry only in two cases:
* Serving a GET request
* Recalculating etag when metadata is stale
  (can be triggered by any type of request)

This change ensures that for requests other than GET, a file is not
opened if the metadata is valid (size and etag accurate). Note that
if metadata is stale, the file is still opened and read to compute etag.
This patch does not change the behaviour of triggering metadata
validation and regeneration for non-GET requests.

Remove redundant syscalls in POST path

2016-04-04T18:01:36+00:00

During process of POST requests which updates object metadata (xattrs),
the following (ordered) sequence of syscalls were being made twice:
open(), fstat(), fgetxattr(), close()

Intuitively, one may assume that a getxattr() and setxattr() is enough
to fulfil the POST request as it is only supposed to update metadata.
But this isn't the case. The above series of syscalls is made first
during disk_file.open(). This will trigger an update of all stale
metadata (outdated size/etag) and the result is retained in a diskfile
class attribute named 'self._metadata'

Instead of using this pre-fetched metadata, the POST path was internally
invoking disk_file.open() again in disk_file.write_metadata(). This is
redundant and serves no purpose. self._metadata was being erased during
the context manager cleanup of disk_file.open()

This change is simple and does the following:
* Don't erase fetched metadata during context manager exit of open()
* Use a different internal variable to detect and raise DiskFileNotOpen
* Re-use self._metadata if available in disk_file.write_metadata()

Here's comparing syscalls made (POST path) with and without this fix:

Rebase to stable/kilo

2016-03-07T18:38:49+00:00

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.
