openstack/swift - swift - OpenDev: Free Software Needs Free Tools

Previously, the OldestAsyncPendingTracker timestamp was stored as a string. This change updates it to be stored as a float.
UpgradeImpact: This will require an additional change to the recon parsers in order to process the timestamp as a float.

Our API ref says "Valid values are json, xml, or plain. The default is
plain." There's no reason our tests ought to use an invalid value; it
will confuse anyone looking at tests for how to do a thing.
Note that tests were passing because invalid values are ignored, so
?format=txt behaves exactly like ?format=plain.

This has been causing most/all of our tox-based jobs to run with
unconstrained dependencies (though test requirements were properly
pinned).

Currently, when object-server serves PUT request and DiskFile
writer write file chunks to disk, there is no explicit
eventlet sleep called. When network outpace the slow disk IO,
it's possible one large and slow PUT request could cause
eventlet hub not to schedule any other green threads for a
long period of time. To improve this, this patch enable the
configurable yield parameter 'cooperative_period' into object
server controller write path.

We would like to remove any Statsd related code from logs.py. That
requires that SwiftLogAdapter no longer provides a StatsdClient
interface by default. However, for backwards compatibility the main
utils.get_logger/get_prefixed_logger entrypoints must provide a
SwiftLogAdapter that does have a StatdsClient interface.
The new utils._patch_statsd_methods helper function is therefore used
to retrospectively patch a SwiftLogAdapter instance with the
StatsdClient interface when necessary. The _patch_statsd_helper is
used in get_logger, and again when we clone a logger in
get_prefixed_logger.

Verify that the reconciler is able to move objects to a container that
has, or will have, versioning enabled, and versions of the moved object
can subsequently be created.

A failing CORS test in the gate discovered that, when running with
eventlet==0.38.0, container and account HEAD requests returned
Content-Type of application/json to clients regardless of the requested
format. This was due to the backend HEAD response no longer having a
Content-Length header, causing the listing_formats middleware to not
modify the returned Content-Type (see Related-Change).
The Related-Change fixed the client facing issue by making
listing_formats middleware ensure the correct Content-Type is returned
to clients even when Content-Length is absent in the backend
response. The Related-Change also ensured that the 204 response to
clients always has a Content-Length header.
This patch directly fixes the problem of backend account and container
server HEADs no longer having 'Content-Length: 0' by adding it
explicitly. This violates the RFC prohibition of a 204 response having
a Content-Length header [1], but preserves Swift's historic behavior
and is consistent with the proxy-server's 204 response to clients.

A failing CORS test in the gate discovered that we were responding
application/json to ?format=txt requests (which is maybe not even a
valid value for that qs param?), but only when running with
eventlet==0.38.0
This avoids the problem of backend container server HEADs no longer
having 'Content-Length: 0' by fixing the client HEAD resp headers before
we check for chunked-transfer resp.
Drive-By: refactor listing_formats to use HeaderKeyDict and always set
Content-Length explicitly

This patch fixes a bug in the Related-Change that causes a prefix to
be added twice at the start of an 'exception' log message.
Previously, PrefixLoggerAdapter.exception would forward to the wrapped
LogAdapter.exception, and not call back to
PrefixLoggerAdapter.process. The prefix therefore needed to be added
in both PrefixLoggerAdapter.exception and PrefixLoggerAdapter.process
(for other log level methods).
SwiftLogAdapter.exception *does* call back to SwiftLogAdapter.process,
and so since the Related-Change it is not necessary to add the prefix
in both the SwiftLogAdapter.exception and SwiftLogAdapter.process
methods.

There's an upstream eventlet bug that seems to cause process hangs
during an atexit hook; unfortunately, that means that every time we
call "once" in probe tests, we can hang indefinitely waiting for a
process that won't terminate.
See https://github.com/eventlet/eventlet/issues/989
Now, wait with a timeout; if it pops, kill the offending process and
hope for the best. Do this by patching out subprocess.Popen.wait, but
only in probe tests -- this ensures that we won't impact any real
systems, while also ensuring a broad coverage of probe tests (as
opposed to, say, plumbing some new wait_timeout kwarg into all the
Manager call sites).

In order to modernize swift's statsd configuration we're working to
separate it from logging. This change is a pre-requisite for the
Related-Change in order to simplfy the stdlib base logger instance
wrapping in a single extended SwiftLogAdapter (previously LogAdapter)
which supports all the features swift's servers/daemons need
from our logger instance interface.

Otherwise, test-run state (eventlet.tpool initialization, in particular)

Previously, queue-clean-up would use the same timestamp/offset as the
tombstone written down in the old policy to clean up now-moved data.
This could lead to bad behaviors, as the reconciler-written tombstone
could itself be enqueued to be reconciled, at the same timestamp. If
that happened, replication would never bring the DB replicas to
consistency, causing the reconciler to get different answers for
whether there was work to do.
Now, add an extra offset bump between the tombstone in the old policy
and queue-clean-up. Also add an extra offset to the moved data in the
new policy, to keep it one ahead of queue-clean-up. New ordering looks
like:
- data/ts in old policy at t0 (as well as queue entry time to move it)
- tombstone in old policy at t0_1
- queue clean-up time at t0_2
- moved data/ts in new policy at t0_3

In the past we have had some async pendings that repeatedly fail for months at a time. This patch adds an OldestAsyncPendingTracker class which manages the tracking of the oldest async pending updates for each account-container pair. This class maintains timestamps for pending updates associated with account-container pairs. It evicts the newest pairs when the max_entries is reached. It supports retrieving the N oldest pending updates or calculating the age of the oldest pending update.
