On process exit, it was possible that the filesystem timestamp
resolution measurement left behind .probe files or even a lock file
for the jgit.config.
Ensure the SAVE_RUNNER is shut down when the process exits (via
System.exit() or otherwise). Move lf.lock() into the try-finally
block when saving the config file.
Delete .probe files on JVM shutdown -- they are created in daemon
threads that may terminate abruptly, not executing the "finally"
clause that normally removes these files.

Implement negative refspecs in JGit fetch, following C Git. Git
supports negative refspecs in source only while this change supports
them in both source and destination.
If one branch is equal to any branch or matches any pattern in the
negative refspecs collection, the branch will not be fetched even if
it's in the toFetch collection.
With this feature, users can express more complex patterns during fetch.

character has been determined initially is always the first character.
Note that if core.commentChar=auto and there is a sequence of squashes,

If LsRemoteCommand is used without repository, the remote URI was not
translated. If the git user config contains e.g.
[url "ssh://git@github.com/"]
insteadOf = https://github.com/
and LsRemoteCommand is called with an HTTPS GitHub repository URL, the
command should actually rewrite this to an SSH URI and use the SSH
transport.
Actually this same problem may exist everywhere Transport is used with
an URIish instead of with a remote name. However, doing this translation
in Transport.open(URIish) and in Transport.open(Repository, URIish,
String) if no remote name is given would change the behavior and might
break assumptions made in existing clients. For instance, EGit's
PushOperation assumes that the URI obtained from PushResult.getURI()
was the same as was passed in to Transport.open(Repository, URIish).
URIs obtained from a RemoteConfig have this translation applied
transparently, and in Transport we cannot know for sure whether or
not a URI has already been translated, if needed. So doing this in
Transport might also lead to translating URIs twice.
Therefore this commit does the translation in LsRemoteCommand, where
we can be sure that it won't affect other use cases. If other cases
besides LsRemoteCommand are found where such a URI translation is
missing, it'll have to be done at higher levels, possibly even in
client code directly.

JGit used only one set of attributes constructed from the global and
info attributes, plus the attributes from working tree, index, and
HEAD.
These attributes must be used to determine whether the working tree is
dirty.
But for actually checking out a file, one must use the attributes from
global, info, and *the commit to be checked out*. Otherwise one may not
pick up definitions that are only in the .gitattributes of the commit
to be checked out or that are changed in that commit with respect to
the attributes currently in HEAD, the index, or the working tree.
Maintain in TreeWalk different Attributes per tree, and add operations
to determine EOL handling and smudge filters per tree.
Use the new methods in DirCacheCheckout and ResolveMerger. Note that
merging in JGit actually used the attributes from the base, not those
from ours, which looks dubious at least. It now uses those from ours,
and for checking out the ones from theirs.
The canBeContentMerged() determination was also done from the base
attributes, and is newly done from the ours attributes. Possibly this
should take into account all three attributes, and only if all three
agree the item can be content merged, a content merge should be
attempted? (What if the binary/text setting changes between base, ours,
or theirs?)
Also note that JGit attempts to perform content merges on non-binary
LFS files; there it used the filter attribute from base, too, even for
the ours and theirs versions. Newly it takes the filter attribute from
the correct tree. I'm not convinced doing content merges on potentially
huge files like LFS files is really a good idea.
Add tests in FilterCommandsTest and LfsGitTest to verify the behavior.
Open question: using index and working tree as fallback for the
attributes of ours (assuming it is HEAD) is OK. But does it also make
sense for base and theirs in merging?

The implementation of push.default=matching was not correct.
It used the RefSpec "refs/heads/*:refs/heads/*", which would push
_all_ local branches. But "matching" must push only those local
branches for which a remote branch with the same name already exists
at the remote.
This RefSpec can be expanded only once the advertisement from the
remote has been received.
Enhance RefSpec so that ":" and "+:" can be represented. Introduce a
special RemoteRefUpdate for such a RefSpec; it must carry through the
fetch RefSpecs to be able to fill in the remote tracking updates as
needed. Implement the expansion in PushProcess.

If core.abbrev is unset or "auto" estimate abbreviation length like C
git does:
- Estimate repository's object count by only considering packed objects,
round up to next power of 2
- With the order of 2^len objects, we expect a collision at 2^(len/2).
But we also care about hex chars, not bits, and there are 4 bits per
hex. So all together we need to divide by 2; but we also want to round
odd numbers up, hence adding one before dividing.
- For small repos use at least 7 hexdigits
- If object database fails to determine object count use 7 hexdigits as
fallback
If it is set to "no" do not abbreviate object-ids.
Otherwise set it to the configured value capped to the range between 4
and length of an unabbreviated object-id.

When no RefSpecs are given, PushCommand until now simply fell back to
pushing the current branch to an upstream branch of the same name. This
corresponds to push.default=current. Any setting from the git config
for push.default was simply ignored.
Implement the other modes (nothing, matching, upstream, and simple),
too. Add a setter and getter for the PushDefault so that an application
can force a particular mode to be used. For backwards compatibility,
use "current" as the default setting; to figure out the value from the
git config, which defaults to "simple", call setPushDefault(null).

BasePackConnection::readAdvertisedRefsImpl was creating an exception by
calling `noRepository`, and then blindly calling `initCause` on it. As
`noRepository` can be overridden, it's not guaranteed to be missing a
cause.
BasePackPushConnection overrides `noRepository` and initiates a fetch,
which may throw a `NoRemoteRepositoryException` with a cause.
In this case calling `initCause` threw an `IllegalStateException`.
In order to throw the correct exception, we now return the
BasePackPushConnection exception and suppress the one thrown by
BasePackConnection

JGit accumulated in MESSAGE_FIXUP commit messages of a fixup sequence,
just like it did in MESSAGE_SQUASH, and on the last step of a sequence
of fixups used that file, after stripping all comment lines, as the
commit message. That also stripped any lines from the original commit
message that happened to start with the comment character.
This is not how this is supposed to work. MESSAGE_FIXUP must contain
the original commit message of the base commit that is amended, and
the file contains the verbatim commit message for the final fixup.[1]
Change the implementation accordingly, and add new tests.

We want to save in the destination repository what manifest created its
structure. This helps to detect and debug failures in the manifest ->
superproject translations. The src commit should be easily readable from
the superproject tip.
Offer an API to write a file in the destination repository. RepoCommand
callers (e.g. gerrit supermanifest plugin) can use this to add a
file with the repo/ref/hash of the manifest.
Alternatives considered to write the source repo/ref/hash:
* .gitattributes of the .gitmodules file. Some updates in the manifest
don't touch the .gitmodules (e.g. a linkfile change), so it can fall
out of sync.
* commit message. Caller would need to follow the commit history to
find the latest modification by repo command. This is not helpful
e.g. for build bots that want to get the value in one call.

RepoCommand parses the manifest to get a list of projects, clears up
conflicts and then writes to the superproject. The first steps are
common but the writing is completely different for bare or "regular"
(with working dir) repository.
Split writing to bare and regular repos into its own classes. This
simplifies RepoCommand class and makes clearer what happens on each side
(e.g. many options apply only to bare repos).
