This change allows individual SLO segments to be downloaded by adding
an extra 'part-number' query parameter to the GET request. You can
also retrieve the Content-Length of an individual segment with a HEAD
request.

md5 is not an approved algorithm in FIPS mode, and trying to
instantiate a hashlib.md5() will fail when the system is running in
FIPS mode.
md5 is allowed when in a non-security context. There is a plan to
add a keyword parameter (usedforsecurity) to hashlib.md5() to annotate
whether or not the instance is being used in a security context.
In the case where it is not, the instantiation of md5 will be allowed.
See https://bugs.python.org/issue9216 for more details.
Some downstream python versions already support this parameter. To
support these versions, a new encapsulation of md5() is added to
swift/common/utils.py. This encapsulation is identical to the one being
added to oslo.utils, but is recreated here to avoid adding a dependency.
This patch is to replace the instances of hashlib.md5() with this new
encapsulation, adding an annotation indicating whether the usage is
a security context or not.
While this patch seems large, it is really just the same change over and
again. Reviewers need to pay particular attention as to whether the
keyword parameter (usedforsecurity) is set correctly. Right now, all
of them appear to be not used in a security context.
Now that all the instances have been converted, we can update the bandit
run to look for these instances and ensure that new invocations do not
creep in.
With this latest patch, the functional and unit tests all pass
on a FIPS enabled system.

This patch adds a new object versioning mode. This new mode provides
a new set of APIs for users to interact with older versions of an
object. It also changes the naming scheme of older versions and adds
a version-id to each object.
This new mode is not backwards compatible or interchangeable with the
other two modes (i.e., stack and history), especially due to the changes
in the namimg scheme of older versions. This new mode will also serve
as a foundation for adding S3 versioning compatibility in the s3api
middleware.
Note that this does not (yet) support using a versioned container as
a source in container-sync. Container sync should be enhanced to sync
previous versions of objects.

We added retries to the functest client ages ago, but object PUTs were
skipped because they used slightly different machinery.
We added retires to PUT later in the related change, but it added it's
own slightly different retry machinery.
Although neither is perfect (e.g. no exponential backoff) - this change
moves them closer together, so that future improvements can help both.

Container servers will store an etag like

which the SLO middleware will break out into separate
"hash": "<MD5 of manifest on disk",
"slo_etag": "\"<MD5 of concatenated ETags\"",
keys for JSON listings. Text and XML listings are unaffected.
If a middleware left of SLO already specified a container update
override, the slo_etag parameter will be appended. If the base header
value was blank, the MD5 of the manifest will be inserted.
SLOs that were created on previous versions of Swift will continue to
just have the MD5 of the manifest in container listings.

A couple times, I've seen tests fail in the gate because we got back a
404 while trying to clean out the test account. The story that gets us
here seems to be:
- One or more object servers take too long to respond to the initial
DELETE request, so the test client gets back a 503 and sleeps so
it can retry.
- Meanwhile, the servers finish writing their tombstones and want to
respond 204 (but probably *actually* respond 408 because the proxy
killed the connection).
- The test client sends its retry, and since the object servers now
have tombstones, it gets back a 404.
But the thing is, this is *outside of the test scope* anyway, we're just
trying to get back to a sane state. If it's gone, s much the better!
For an example of this, see the failures on patchset 3 of
https://review.openstack.org/#/c/534978 (which both failed for the same
reason on different tests).

Add a symbolic link ("symlink") object support to Swift. This
object will reference another object. GET and HEAD
requests for a symlink object will operate on the referenced object.
DELETE and PUT requests for a symlink object will operate on the
symlink object, not the referenced object, and will delete or
overwrite it, respectively.
POST requests are *not* forwarded to the referenced object and should
be sent directly. POST requests sent to a symlink object will
result in a 307 Error.
Historical information on symlink design can be found here:

An SLO PUT requires that we HEAD every referenced object; as a result, it
can be a very time-intensive operation. This makes it difficult as a
client to differentiate between a proxy-server that's still doing work and
one that's crashed but left the socket open.
Now, clients can opt-in to receiving heartbeats during long-running PUTs
by including the query parameter
heartbeat=on
With heartbeating turned on, the proxy will start its response immediately
with 202 Accepted then send a single whitespace character periodically
until the request completes. At that point, a final summary chunk will be
sent which includes a "Response Status" key indicating success or failure
and (if successful) an "Etag" key indicating the Etag of the resulting SLO.
This mechanism is very similar to the way bulk extractions and deletions
work, and even the way SLO behaves for ?multipart-manifest=delete requests.
Note that this is opt-in: this prevents us from sending the 202 response
to existing clients that may mis-interpret it as an immediate indication
of success.

Currently the functional tests fail if the storage_url contains a quoted
IPv6 address because we try to split on ':'.
But actually we don't need to split hostname and port only in order to
combine it back together lateron. Use the standard urlparse() function
instead and work with the 'netloc' part of the URL which keeps hostname

For now, last modified timestamp is supported only on
object listing. (i.e. GET container)
For example:
GET container with json format results in like as:
[{"hash": "d41d8cd98f00b204e9800998ecf8427e", "last_modified":
"2015-06-10T04:58:23.460230", "bytes": 0, "name": "object",
"content_type": "application/octet-stream"}]
However, container listing (i.e. GET account) shows just a dict
consists of ("name", "bytes", "name") for each container.
For example:
GET accounts with json format result in like as:
[{"count": 0, "bytes": 0, "name": "container"}]
This patch is for supporting last_modified key in the container
listing results as well as object listing like as:
[{"count": 0, "bytes": 0, "name": "container", "last_modified":
"2015-06-10T04:58:23.460230"}]
This patch is changing just output for listing. The original
timestamp to show the last modified is already in container table
of account.db as a "put_timestamp" column.
Note that this patch *DOESN'T* change the put_timestamp semantics.
i.e. the last_modified timestamp will be changed only at both PUT
container and POST container.
(PUT object doesn't affect the timestamp)
Note that the tuple format of returning value from
swift.account.backend.AccountBroker.list_containers is now
(name, object_count, bytes_used, put_timestamp, 0)
* put_timestamp is added *

Addresses a TODO in test/functional/test_account.py where
an account metadata test was having to clean up tempurl keys
in the account metadata that were left by another test in
a different module. This cleanup is necessary because tests
in test_account.py fail if there is any pre-existing
account metadata.
This patch:
* makes the tempurl tests clean up their keys from account
metadata.
* makes the test_account.py:TestAccount class remove any
pre-existing metadata before attempting any tests and
replacing that metadata when all the tests in that class
have completed. This is more robust than the existing code
which only removes any tempurl keys that might be in the
account - now you could have x-account-meta-foo = bar in
the test account and test_account.py will still pass.
* consolidates some common setup code currently repeated for
many of the functional test classes into into a BaseEnv class.

This patch includes a couple of small functional test improvement.
A. Change swift_test_client.File.sync_metadata to follow Swift object
metadata semantics:
swift_test_client.File.sync_metadata is designed to post object user
metadata to an object. However, prior to this patch, the
swift_test_client.File instance keeps the existing object metadata as
its member attribute and if sync_metadata is called, it sends both
existing metadata and incomming metadata from caller. It looks to result
in the odd state as if Swift keeps the existing metadata when POST
object requested.
To tell the correct Swift object metadata semantics, when POST object
requested, the existing metadata in the stored object should be gone
even if no metadata is overwritten.
i.e.
if POST object with 'X-Object-Meta-Key: Val' to a stored object with
'X-Object-Meta-foo: bar', it will result in an object with
'X-Object-Meta-Key' (note that X-Object-Meta-Foo will be deleted)
The prior behavior sometimes make us confused in the reviw [1] so that,
this patch fixes it to send only incomming metadata if it's set.
B. Check the response status code more strictly for ObjectVersioning case
This patch fixes test_versioning_check_acl on both TestObjectVersioning and
TestObjectVersioningHistoryMode to assert the response status code
explisitly instead of asserting just "ResponseError". (e.g. 403 when trying
to delete object from other account)

This patch is follow up for [1] and [2] to add new functional
tests for versioned_writes middlware 'history' mode.
(i.e. using X-History-Location header to a container).
The new test class, TestObjectHistoryModeVersioning, will use obvious
setting the mode via new X-History-Location header, since the change [2],
the setting X-Versions-Mode header added since [1] for incomming request has
been deprecated. Hence, since [2], the syntax for stack mode is back to
be same with older Swift than [1] so that the only thing we need now is
just adding a test suite for the new X-History-location.
It means the API has been changing like:
---------------
For stack mode:
---------------
Older than [1]:
X-Versions-Location
[1]~[2]:
X-Vesions-Location (and X-Versions-Mode: 'stack' for obvious)
Newer than [2]:
X-Vesions-Location
-----------------
For history mode:
-----------------
Older than [1]:
(Not supported)
[1]~[2]:
X-Vesions-Location and X-Versions-Mode: 'history'
Newer than [2]:
X-History-Location
Note that this functional tests work on newer swift than [2].
And then, this patch also sets allow_versioned_writes=True
for in-process testing (the container server allow_versions
option was already set, so this is just enabling in the middleware
too). That means that in-process functional tests (such as run by
the tox envs func-in-process-*) because history mode requires the
middleware allow_versioned_writes option to be explicity set to True.

This patch enables to show a x-put-timestamp as
a last-modified header in container-server.
Note that the last-modified header will be changed only when a
request for container (PUT container or POST container) comes into
Swift. i.e. some requests for objects (e.g. PUT object, POST object)
will never affect the last-modified value but only when using
python-swiftclient like as "swift upload", the last-modified will
be close to the upload time because python-swiftclient will make
a PUT container request for "swift upload" each time.

test/functional/tests.py:TestAccount.testAccountHead relies
on the account having a known number of containers. The test
setup attempts to delete all existing containers but this fails
a container has versions (and so is not emptied, and cannot be
deleted). The tests then fails because the expected number of
containers does not match the actual.
'bin/resetswift' before running tests will obviously clear all
state but is not always convenient.
This change removes any x-versions-location header before deleting
containers during test setUp.

swift post source -H 'x-versions-location: target'
