Added the new field to be able to log the access key during the
s3api calls, while reserving the field to be filled with auth relevant
information in case of other middlewares. Added respective code to
the tempauth and keystone middlewares.
Since s3api creates a copy of the environ dict for the downstream
request object when translating the s3req.to_swift_req the environ
dict that is seen/modifed in other mw module is not the same instance
seen in proxy-logging - using mutable objects get transfered into the
swift_req.environ.
Change the assert in test_proxy_logging from "the last field" to
the index 21 in the interests of maintainability.
Also added some regression tests for object, bucket and s3 v4 apis and
updated the documentation with the details about the new field.

S3 stopped returning DisplayNamme in the Owner field of object
listings [1], so the tests need to stop asserting that it is present.
Further work is needed to drop DisplayName from the Swift s3api
responses [2].

The RuntimeError gives more of a hint than the TypeError, but we haven't
really solved the issue. If there's a busted pyeclib install, it's safe
to assume it won't have ISA-L alongside it; just proceed assuming it's
not available.

ssync unit tests would sometimes fail when making assertions about the
ssync receiver log messages. Test runner output would show that the
messages were eventually being logged. However, the assertions could
be made before the ssync receiver request thread had completed.
A trampoline had been previously been used to workaround this, but
that is clearly insufficient. The author found that increasing the
trampoline interval would help reduce the rate of failures, but not
eliminate them.
This patch introduces a custom GreenPool for the unit test wsgi object
server so that tests can deterministically wait for the receiver
request handling thread to exit before making assertions.

with "TypeError: 'NoneType' object is not iterable". This patch

Previously it was possible for a Timestamp to have inconsistent raw
and normal values. For example:
>>> ts1 = Timestamp(1755077566.523385)
>>> (ts1.normal, ts1.raw, (~ts1).normal)
('1755077566.52339', 175507756652338, '8244922433.47661')
This results in the invert function not being reliably reversible:
(~(~ts1)).normal
'1755077566.52338'
The cause is that the normal value is based on Timestamp.timestamp
which preserves the precision of the value given to the constructor,
whereas the invert function uses the limited precision raw value.
This patch forces Timestamp.timestamp to have the limited precision
value of Timestamp.raw.

If a PUT subrequest body iterator times out while the object server is
reading it, the object server will handle the timeout and return a 500
response to the ssync receiver.
Previously, the ssync receiver would attempt to drain the remainder of
the subrequest body iterator and then resume reading the next
subrequest from the SSYNC body. However, the attempt to drain the
subrequest iterator would fail (silently) because the timeout had
already caused the iterator to exit.
The ssync receiver would therefore treat any remaining subrequest body
as the preamble to the next subrequest. This remaining subrequest body
content was likely to cause the protocol parsing to fail, but in the
worst case could be erroneously interpreted as a valid subrequest.
(The exact failure mechanism depends on what state the
eventlet.wsgi.Input is left in when the timeout fired.)
This patch ensures that the ssync receiver will terminate processing
an SSYNC request if an exception occurs while reading a subrequest
body.

This doesn't fix *all* non-utf8 paths, but
- it was easy enough to avoid the non-swift ones, which have been seen
 in prod, and
- there's ample precedent in other middlewares for checking API version.

There is an infinite loop if multiple quota limits are set and exceeded,
eventually resulting in a 500 response due to a RecursionError ("maximum
recursion depth exceeded").
The issue is the delayed rejection, required to support container_acls.
If any quota is exceeded the middleware needs to return directly,
without proceeding to check other quota settings.
The fix is basically to add a "return self.app". However, there is quite
some redundant code, thus moving this into its own method.
Another test with multiple exceeded quotas has been added, which is
failing without the bugfix.

Previously, when the audit process detected gaps and/or overlaps in a
DB's shard ranges, it would log a warning that included a list of all
impacted shard ranges. The log message can grow long when there are
gaps or overlaps involving many shard ranges: so long that syslog
might raise an OSError (Message too long).
This patch shortens these log warning messages to only include a count
of the number of gaps and/or overlaps. The count may still be useful
to observe how a problem has developed over time. The detailed
information is better accessed using the swift-manage-shard-ranges
repair command.

There's a bunch of moving pieces here:
- Add a new RingWriter class.
 Stick it in a new swift.common.ring.io module. You *can* use it like
 the old gzip file, but you can also define named sections which can
 be referenced later on read. Section names may be arbitrary strings,
 but the "swift/" prefix is reserved for upstream use. Sections must
 contain a single length-value encoded BLOB. If sections are used, an
 additional BLOB is written at the end containing a JSON section-index,
 followed by an uncompressed offset for the index.
 Move RingReader to ring/io.py, too.
- Clean up some ring metadata handling:
 - Drop MD5 tracking in RingReader. It was brittle at best anyway, and
 nothing uses it. YAGNI
 - Fix size/raw_size attributes when loading only metadata.
- Add the ability to seek within RingReaders, though you need to know
 what you're doing and only seek to flush points.
- Let RingBuilder objects change how wide their replica2part2dev_id
 arrays are. Add a dev_id_bytes key to serialized ring metadata.
 dev_id_bytes may be either 2 or 4, but 4 requires v2 rings. We
 considered allowing dev_id_bytes of 1, but dropped it as unnecessary
 complexity for a niche use case.
- swift-ring-builder version subcommand added, which takes a ring. This
 lets operators see the serialization format of a ring on disk:
 $ swift-ring-builder object.ring.gz version
 object.ring.gz: Serialization version: 2 (2-byte IDs), build version: 54

We stopped writing pickled rings more than twelve years ago. Any
cluster that was going to upgrade from then has, or can pick any of
the multitude of intermediary releases to pause at and push rings.
We can also safely assume that regions will be present for devices;
that change is nearly as old.
As a side-effect, clean up some old tests that did nonsense things
like having 7 assignments per row for a part-power-2 ring.
UpgradeImpact: remove ability to read rings written by swift <1.7.0
circa 2012

Add anycrc as a soft dependency in case ISA-L isn't available.
Plus we'll want it later: when we start writing down checksums,
we'll need it to combine per-part checksums for MPUs.
Like with crc32c, we won't provide any pure-python version as the
CPU-intensiveness could present a DoS vector. Worst case, we 501
as before.

See https://docs.aws.amazon.com/AmazonS3/latest/userguide/checking-object-integrity.html
for some background.
This covers both "normal" objects and part-uploads for MPUs. Note that
because we don't write down any client-provided checksums during
initiate-MPU calls, we can't do any verification during complete-MPU
calls.
crc64nvme checksums are not yet supported; clients attempting to use
them will get back 501s.
Adds crt as a boto3 extra to test-requirements. The extra lib provides
crc32c and crc64nvme checksum support in boto3.
