The FS.setAsyncFileStoreAttributes() static method calls
FileStoreAttributes.setBackground() as its implementation, but there are
other public attributes on this inner class already and there isn't a
real reason why this needs to be private.
By making it public we allow callers to be able to invoke it directly.
Although it doesn't appear that it would make a difference, by calling a
static method on the FS class, all static fields and the transitive
closure of class dependencies must be loaded and initialised, which can
be non-trivial.
Callers referring to FS.setAsyncFileStoreAttributes() may be replaced
with FS.FileStoreAttributes.setBackground() with no change of behaviour
other than improved performance due to less class loading required.

The change Ic0b974fa (c217d33, "Documentation/technical/reftable:
improve repo layout") defines a new repository layout, which was
agreed with the git-core mailing list.
It addresses the following problems:
* old git clients will not recognize reftable-based repositories, and
look at encompassing directories.
* Poorly written tools might write directly into
.git/refs/heads/BRANCH.
Since we consider JGit reftable as experimental (git-core doesn't
support it yet), we have no backward compatibility. If you created a
repository with reftable between mid-Nov 2019 and now, you can do the
following to convert:
mv .git/refs .git/reftable/tables.list
git config core.repositoryformatversion 1
git config extensions.refStorage reftable

FS_Win32_Cygwin replaces backslashes by / as a side-effect of
relativize(). When support for core.hooksPath was added, paths were
relativized in a different place using Path.resolve(), which doesn't
do that transformation. As a result hooks could not be run on Cygwin
in some cases.
Do the transformation in FS_Win32_Cygwin.runInShell(). In all other
places, File or Path objects are used, which give no guarantee about
the file separator (typically the system-dependent default separator),
so doing the transformation earlier still wouldn't guarantee that
sh.exe indeed gets a command string using forward slashes.

This reverts commit e102bbed99.
Resolving the hostname comes with a performance penalty. We no longer
store the timestamp resolution in the global git config which might be
copied around to other machines but in a dedicated jgit config meant for
automatically determined options like timestamp resolution. Hence there
is no strong reason anymore to have a hardware specific identifier in
the subsection name of file timestamp resolution options.

The Java Language Specification recommends listing modifiers in
the following order:
1. Annotations

4. private
5. abstract
6. static
7. final
8. transient
9. volatile
10. synchronized
11. native

Not following this convention has no technical impact, but will reduce
the code's readability because most developers are used to the standard
order.

The topological sort algorithm in TopoSortGenerator for RevWalk may mix
multiple lines of history, producing results that differ from C git's
git log whose man page states: "Show no parents before all of its
children are shown, and avoid showing commits on multiple lines of
history intermixed." Lines of history are mixed because
TopoSortGenerator merely delays a commit until all of its children have
been produced; it does not immediately produce a commit after its last
child has been produced.
Therefore, when the last child of a commit has been produced, unpop the
commit so that it will be returned upon the subsequent call to next() in
TopoSortGenerator. To avoid producing duplicates, mark commits that
have not yet been produced as TOPO_QUEUED so that when a commit is
popped, it is produced if and only if TOPO_QUEUED is set.
To support nesting with other generators that may produce the same
commit multiple times like DepthGenerator (for example, StartGenerator
does this), do not increment parent inDegree for the same child commit
more than once.
Modify tests that assert that TopoSortGenerator mixes lines of commit
history.

The ReftableCompactor supported a byteLimit, but this is currently
unused. The FileReftableStack has a more sophisticated strategy that
amortizes compaction costs.
Rename min/maxUpdateIndex to reflogExpire{Min,Max}UpdateIndex to
reflect their purpose more accurately.
Since reflogs are generally pruned chronologically (oldest entries are
expired first), one can only prune entries on full compaction, so they
should not be set by default.
Rephrase the function Reader#minUpdateIndex and maxUpdateIndex. These
vars are documented to affect log entries, but semantically, they are
about ref entries. Since ref entries have their timestamps
delta-compressed, it is important for the min/maxUpdateIndex values to
be coherent between different tables.
The logical timestamps for log entries do not have to be coherent in
different tables, as the timestamps of a log entry is part of the key.
For example, a table written at update index 20 may contain a tombstone
log entry at timestamp 1.
Therefore, we set ReftableWriter's min/maxUpdateIndex from the merged
tables we are compacting, rather than from the compaction settings
(which should only control reflog expiry.)
The previous behavior could drop log entries erroneously, especially
in the presence of tombstone log entries. Unfortunately, testing this
properly requires both an API for adding log tombstones, and a more
refined API for controlling automatic compaction. Hence, no test.

Commit 6216b0de changed the behavior of the setMirror(),
setCloneAllBranches(), and setBranchesToClone() operations. Before
that commit, these could be set and reset independently and only in
call() it would be determined what exactly to do. Since that commit,
the last of these calls would determine the operation. This means
that the sequence
cloneCommand.setCloneAllBranches(true);
cloneCommand.setBranchesToClone(/* some list of refs */);
would formerly do a "clone all" giving a fetch refspec with wildcards
+refs/heads/*:refs/remotes/origin/*
which picks up new upstream branches, whereas since commit 6216b0de
individual non-wildcard fetch refspecs would be generated and new
upstream branches would not be fetched anymore.
Undo this behavioral change. Make the operations independently settable
and resettable again, and determine the exact operation only in call():
mirror=true > cloneAll=true > specific refs, where ">" means "takes
precedence over", and if none is set assume cloneAll=true.
Note that mirror=true implies setBare(true).

When fetching remote objects, WalkFetchConnection searches remote
packs in the order provided by WalkRemoteObjectDatabase:getPackNames.
Previously, for TransportAmazonS3, the packs were in no particular
order. This resulted in potential many extra calls to get pack idx
files.
This change modifies TransportAmazonS3 and AmazonS3 so that
getPackNames returns a list sorted with the most recently modified
packs first. In the case of fetching recent changes to a repo,
this dramatically reduces the number of packs searched and speeds
up fetch.
Note: WalkRemoteObjectDatabase::getPackNames does not specify
the order of the returned names.
Testing: did "mvn clean install" in root dir and all tests passed.
And manually constructed some S3 repos and using jgit.sh
confirmed that the freshest pack was checked first.
