Write packed-refs directly when cloning
When we are cloning we have no refs at all yet, and there cannot
(or at least should not) be any other thread doing something with
refs yet.
Locking loose refs is thus not needed, since there are no loose
refs yet and nothing should be trying to create them concurrently.
Let's skip the whole loose ref locking when we are cloning a repository.
As a result, JGit will write the refs directly to the packed-refs
file, and will not create the refs/remotes/ directories nor the
lock files underneath when cloning and packed refs are used. Since
no lock files are created, any problems on case-insensitive file
systems with tag or branch names that differ only in case are avoided
during cloning.
Detect if we are cloning based on the following heuristics:
* HEAD is a dangling symref
* There is no loose ref
* There is no packed-refs file
Note, however, that there may still be problems with such tag or
branch names later on. This is primarily a five-minutes-past-twelve
stop-gap measure to resolve the referenced bug, which affects the
Oxygen.2 release.

Config: Remove the include functionality
The Config class must be safe to run against untrusted input files.
Reading arbitrary local system paths using include.path is risky for
servers, including Gerrit Code Review.
This was fixed on master [1] by making "readIncludedConfig" a noop
by default. This allows only FileBasedConfig, which originated from
local disk, to read local system paths.
However, the "readIncludedConfig" method was only introduced in [2]
which was needed by [3], both of which are only on the master branch.
On the stable branch only Config supports includes. Therefore this

Silence API warnings for reintroduced ResolveMerger#processEntry
This was silenced before but suppression was unintentionally lost in
merge commit 6858339c1e2878d5c5dc6cc9b422f9802be950ae.
This method was removed in 4.9.0 and reintroduced in 4.9.1 to avoid
breaking EMF compare versions which were built against older versions.
When a GC operation is interrupted, temporary packs and indexes can be
left on the pack folder. In big, busy repositories this can lead to
significant amounts of wasted disk space if this interruption is done
with a certain frequency.
Remove stale temporary packs and indexes at the end of the GC process so
they do not accumulate. To avoid interfering with a possible concurrent
JGit GC process in the same repository, only delete temporary files that
are older than one day.
When running on NFS there was a chance that JGits LockFile
semantic is broken because File#createNewFile() may allow
multiple clients to create the same file in parallel. This
change provides a fix which is only used when the new config
option core.supportsAtomicCreateNewFile is set to false. The
default for this option is true. This option can only be set in the
global or the system config file. The repository config file is not
taken into account in this case.
If the config option core.supportsAtomicCreateNewFile is true
then File#createNewFile() is trusted and the behaviour doesn't
change.
But if core.supportsAtomicCreateNewFile is set to false then after
successful creation of the lock file a hardlink to that lock file is
created and the attribute nlink of the lock file is checked to be 2. If
multiple clients manage to create the same lock file nlink would be
greater than 2 showing the error.

Yet another work-around for a Jsch bug: timeouts

"ServerAliveInterval" and "ConnectTimeout" as read from
the config file to java.net.Socket.setSoTimeout(). That
method expects milliseconds, but the values in the config

The missing conversion in Jsch means that the timeout is

that very short time frame, Jsch kills the connection and
then throws an exception with a message such as "session is

Applications that use ObjectInserters to create lots of individual
objects may prefer to avoid cluttering up the object directory with
loose objects. Add a specialized inserter implementation that produces a
single pack file no matter how many objects. This inserter is loosely
based on the existing DfsInserter implementation, but is simpler since
we don't need to buffer blocks in memory before writing to storage.
An alternative for such applications would be to write out the loose
objects and then repack just those objects later. This operation is not
currently supported with the GC class, which always repacks existing
packs when compacting loose objects. This in turn requires more
CPU-intensive reachability checks and extra I/O to copy objects from old
packs to new packs.
So, the choice was between implementing a new variant of repack, or not
writing loose objects in the first place. The latter approach is likely
less code overall, and avoids unnecessary I/O at runtime.
The current implementation does not yet support newReader() for reading
back objects.

ObjectDirectory: Remove last modified check in insertPack
GC explicitly handles the case where a new pack has the same name as an

the existing pack.
The loop in insertPack tried to short-circuit when inserting a new pack,
to avoid walking more of the pack list than necessary. Unfortunately,
this means it will never get to the check for an identical name,
resulting in a duplicate entry for the same PackFile in the pack list.

Ensure ReflogWriter only works with a RefDirectory
The ReflogWriter constructor just took a Repository and called
getDirectory() on it to figure out the reflog dirs, but not all
Repository instances use this storage format for reflogs, so it's
incorrect to attempt to use ReflogWriter when there is not a
RefDirectory directly involved. In practice, ReflogWriter was mostly
only used by the implementation of RefDirectory, so enforcing this is
mostly just shuffling around calls in the same internal package.
The one exception is StashDropCommand, which writes to a reflog lock
file directly. This was a reasonable implementation decision, because
there is no general reflog interface in JGit beyond using
(Batch)RefUpdate to write new entries to the reflog. So to implement
"git stash drop <N>", which removes an arbitrary element from the
reflog, it's fair to fall back to the RefDirectory implementation.
Creating and using a more general interface is well beyond the scope of
this change.
That said, the old behavior of writing out the reflog file even if
that's not the reflog format used by the given Repository is clearly
wrong. Fail fast in this case instead.

* Scheme and host must match exactly case-insensitively.
* An optional user name must match exactly.
* Ports must match exactly after default ports have been filled in.
* The path of a subsection, if any, must match a segment prefix of
the path of the URL.
* Matches with user name take precedence over equal-length path
matches without, but longer path matches are preferred over
shorter matches with user name.

ReceivePack: clear advertised .haves if application changes refs
An application can choose to invoke setAdvertisedRefs multiple times,

This can lead to a server over-advertising with ".have" lines if the

this to a subset. ReceivePack will advertise the unique objects from
the first hook using ".have" lines, which may lead to a huge
advertisement sent to the client.
This can also contribute to a very slow connectivity check after the
pack is parsed as ReceivePack calls markUninteresting on every commit
in advertisedHaves. This may require expanding a lot of subtrees to
mark all trees as uninteresting as well. On a very big repository
this can lead to a many-second stall.

Fix some tests for running in bazel
Some tests call out to external cgit. Those tests all failed for me
locally on Mac. Turned out that the reason was that the system git
config used by the git in the bazel run contained paths with ~/ but
somehow $HOME was not set. As a result the external git returned
with exit code 128.
Fix this by passing along $HOME explicitly. Also improve assertions
to make sure we do get the stderr of the external command in the
test log.
I hadn't noticed that until now because apparently the maven build
does pass along $HOME.

DfsFsck: reduce memory usage during verifyIndex
Don't convert a lot of ObjectId to String stored in generic
java.util.HashSet. This is a very expensive way to store objects.
Instead rely on "this" from the FsckPackParser to lookup information
about the objects in this pack file, which lets the verify code avoid
sorting the object list.
Use ObjectIdOwnerMap, which is the most efficient format JGit has
for storing lots of objects.

DfsFsck: run connectivity check pass exactly once
The simpler algorithm is to load all branch tips into an ObjectWalk
and run that walk exactly once. This avoids redoing work related to
parsing and considering trees reused across side branches.
Move the connectivity check into its own helper method. This moves it
left one level of identation, and makes it easier to fit the method's
logic with less line wrapping.
Add a "Counting objects..." progress monitor around this phase. Its
what is used when a server receives a push and is also trying to
verify the client sent all required objects.
