Repository has a usage counter that is initialized to 1 at
instantiation and this counter is decremented when Repository.close
method is called. There is also a Repository.incrementOpen method that
RepositoryCache uses to increment the usage count when it's returning a
repository that is already opened.
The problem was that RepositoryCache was incrementing the usage count
for repositories that it just opened or registered. The usage count was
2 when it should have been 1.
Incrementing usage count is now only be done for repository that are
served from the cache.
This bug is causing slow memory increase of our Gerrit server until the
server become slow. Even if the RepositoryCache is using SoftReference,
it seems that the JVM is not garbage collecting the repositories because
it's not yet on the edge of being out of memory.
To test this change, I replicated all repositories(11k) from Gerrit
master to one slave. The Gerrit master used memory after this test was
10GB without this change and 3.5GB with.

JGit's Garbage Collector is repacking relevant objects into new
packfiles and is afterwards deleting the now obsolete packfiles. But to
prevent problems caused by race conditions JGit was not deleting
packfiles when they are too young. The same mechanism as for loose
objects and the config parameter gc.pruneExpire was used.
But JGit was reusing the parameter gc.pruneExpire also for packfiles
which may cause a lot of filesystem consumption if gc.pruneExpire was
set to the default of 2 weeks. Only two weeks after packfile creation gc
was allowed to delete this packfile.
This change introduces a new config paramter gc.prunePackExpire with a
default of "1.hour". This parameter is used when packfiles are deleted.
Only packfiles older than the specified time can be deleted.
For loose objects the behaviour is not changed and only the old
parameter gc.pruneExpire is relevant.

The default author and committer objects in TestRepository were
initialized statically and did not use the MockSystemReader passed into
the TestRepository ctor. Make these fields non-static and initialize
them with a consistent clock.
Also make the author and commiter name and email strings public for
tests that want to verify against them.

The FileLfsRepository.out member could have been accessed from multiple
threads which would corrupt the content.
Don't store the AtomicObjectOutputStream in the FileLfsRepository.out but
move it to the ObjectUploadListener which is instantiated per-request.
Add a parallel upload test.

With ignoreRemoteFailures set to true, we can ignore remote failures
(e.g. the branch of a project described in the manifest file does not
exist), skip that project and continue to the next one, instead of fail
the whole operation.

This commit introduces a FileModeStrategy to
the FileTreeIterator class. This provides a way to
allow different modes of traversing a file tree;
for example, to control whether or not a nested
.git directory should be treated as a gitlink.

14dfa70520 fixed the problem that HEAD wasn't added to the reftree when
rebuilding the reftree in an empty repository where HEAD isn't yet
resolvable. Since non-resolvable refs are filtered out by
RefDatabase.getRefs(ALL) we have to add HEAD to the reftree explicitly
in this special case.
This fix resulted in another bug: rebuilding the reftree in a repository
which has a resolvable HEAD failed with a DirCacheNameConflictException
in RefTree.apply(). If HEAD is resolvable RefDatabase.getRefs(ALL) does
not filter out HEAD. This results in two identical CREATE commands for
HEAD which RefTree.apply() refuses to execute.
Fix this by no longer creating a duplicate CREATE command for HEAD.

Add a storage implementation storing large objects in Amazon S3.
The AmazonS3Repository pre-signs download and upload requests.
AWS access and secret key are expected to be in the
$HOME/.aws/credentials file in the following format:
[default]
accessKey = ...
secretKey = ...
Use AWS version 4 request signing [1] because it is more secure and
supported by all regions. The version 3 signing is not supported in
newer regions.
In follow up changes we should:
- implement getVerifyAction() and do actual verification. Subclasses of
S3Repository can implement caching for object meta data (size) in order
to avoid extra roundtrips to S3. Verification should ensure that meta
data store and content of S3 storage are in sync
- HEAD request used in S3Repository.getSize() seems to always return
Content-length 0 in contrast to the documentation [2]. So getSize() does
detect if the object exists in S3 or not but in case the object exists
it always returns size 0

If the client sends a SHA-1 that the server does not recognize echo
this back to the client with an explicit error message instead of
the generic "internal server error".
This was always the intent of the implementation but it was being
dropped on smart HTTP due to the UploadPackServlet catching the
PackProtocolException, discarding the buffered message UploadPack
meant to send, and sending along a generic message instead.

There's only one test method in this module and it's quite long, so
rather than using a try-with-resource and having to indent a huge
block of existing code, make the Git a member variable that gets
initialised and closed in @Before and @After annotated methods.
The methods are named 'before' and 'after' rather than the conventional
'setUp' and 'tearDown' so as not to conflict with the names of the
existing methods in LocalDiskRepositoryTestCase.
