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 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.

desire of expanding an array in the failure case - can have a

Compared to that, checking an array for length - even if done many

sh.exe -c 'C:\path\script "$@"' 'C:\path\script' other args
call
sh.exe -c '$0 "$@"' 'C:\path\script' other args
which avoids this escape processing.
Note that this is not specific to Windows. If the path or the script

When a conflicting file was blamed, JGit would not identify lines
coming from the merge parents. The main cause for this was that
Blame and BlameCommand simply added the first DirCacheEntry found
for a file to its queue of candidates (blobs or commits) to consider.
In case of a conflict this typically is the merge base commit, and
comparing a auto-merged contents against that base would yield
incorrect results.
Such cases have to be handled specially. The candidate to be
considered by the blame must use the working tree contents, but
at the same time behave like a merge commit/candidate with HEAD
and the MERGE_HEADs as parents. Canonical git does something very
similar, see [1].
Implement that and add tests.
I first did this for the JGit pgm Blame command. When I then tried
to do the same in BlameCommand, I noticed that the latter also
included some fancy but incomplete CR-LF handling. In order to
be able to use the new BlameGenerator.prepareHead() also in
BlameCommand this CR-LF handling was also moved into BlameGenerator
and corrected in doing so.
(Just considering the git config settings was not good enough,
CR-LF behavior can also be influenced by .gitattributes, and even
by whether the file in the index has CR-LF. To correctly determine
CR-LF handling for check-in one needs to do a TreeWalk with at
least a FileTreeIterator and a DirCacheIterator.)

expensive and in the incremental reachability check, it is probably not
required for all elements in the collection.

the conversion from ObjectId to RevCommit in the stream (i.e. on

UploadPack needs to check if object ids that weren't advertised before
are reachable from the references visible to the user. In the
bitmap-based reachability check, this is done incrementally: checking
against one reference, if anything remaining adding a second and so on.
It is more efficient to check first more common references (e.g. refs/heads/*)
Sort the references for the reachability checker. This should solve the
connectivity earlier and require less bitmap creation and less memory.

Reftable is a binary, block-based storage format for the ref-database.
It provides several advantages over the traditional packed + loose
storage format:
* O(1) write performance, even for deletions and transactions.
* atomic updates to the ref database.
* O(log N) lookup and prefix scans
* free from restrictions imposed by the file system: it is
case-sensitive even on case-insensitive file systems, and has
no inherent limitations for directory/file conflicts
* prefix compression reduces space usage for repetitive ref names,
such as gerrit's refs/changes/xx/xxxxx format.
FileReftableDatabase is based on FileReftableStack, which does
compactions inline. This is simple, and has good median performance,
but every so often it will rewrite the entire ref database.
For testing, a FileReftableTest (mirroring RefUpdateTest) is added to
check for Reftable specific behavior. This must be done separately, as
reflogs have different semantics.
Add a reftable flavor of BatchRefUpdateTest.
Add a FileReftableStackTest to exercise compaction.
Add FileRepository#convertToReftable so existing testdata can be
reused.

Some applications using JGit use their own repository caching. In
such applications, it may be needlessly inefficient to create new

Provide a way to configure a SubmoduleWalk with a factory to create
BaseRepositoryBuilders to use to create repositories, and use it in

additional factory as parameter.
An application that caches Repository instances (for instance EGit)
can use a factory that provides builders that don't create a new
Repository instance but that return the already cached instance, if
one is available. Note that in such a case, the application may need
to be prepared to deal with IndexDiff.diff() also _closing_ the
obtained repository; if the application expects its cached Repository
instances to remain open while being cached, it'll have to use
Repository.incrementOpen() to prevent that the repository instance
gets closed.

This avoids polluting hand-crafted user level config with
auto-configured options which might disturb in environments where
the user level config is replicated between different machines.
Add a jgit config as parent of the system level config. Persist
measured timestamp resolutions always in this jgit config and read it
via the user global config. This has the effect that auto-configured
timestamp resolution will be used by default and can be overridden in
either the system level or user level config.
Store the jgit config under the XDG_CONFIG_HOME directory following the
XDG base directory specification [1] in order to ensure that we have
write permissions to persist the file. This has the effect that each OS
user will use its jgit config since they typically use different
XDG_CONFIG_HOME directories.
If the environment variable XDG_CONFIG_HOME is defined the jgit config
file is located at $XDG_CONFIG_HOME/jgit/config otherwise the default is
~/.config/jgit/config.
If you want to avoid redundant measurement for different OS users
manually copy the values measured and auto-configured for one OS user to
the system level git config.

This is potentially confusing behavior, because you can write data

used by default. In that case, use '<', i.e., require an exact match
on the OpenPGP e-mail address.
Also handle the optional "0x" prefix for (partial) key fingerprints.

The effect of assert is defined by compiler flags, so this code
introduced a potential vector for corruption.

Currently when a GPG key is looked up using a user identity the first
key from the keyring that has this user identity is returned.
The code was changed to instead return the first signing [S] key in this
keyring and only return the master key if no such signing key was found.
If the master key also does not have the signing flag set null is
returned instead.

Currently when a subkey is configured for signing via the git
user.signingkey configuration option the first key from the keyring for
this subkey would be returned for use (master key). The code has been
changed to return the requested key from the keyring instead.

Support the core.hooksPath git config. This can be an absolute or
relative path of a directory where to find git hooks; a relative
path is resolved relative to the directory the hook will run in.

Since [1] the gerrit project includes jgit as a submodule, and has this
warning enabled, resulting in 100s of warnings in the console.
Also enable the warning here, and fix them.
At the same time, add missing braces around adjacent and nearby one-line
blocks.

This introduces ReftableBatchRefUpdate and ReftableDatabase, as
generic classes, with some code moved to DfsReftableBatchRefUpdate and
DfsReftableDatabase.
Clarify thread-safety requirements by asserting locked status in
accessors, and acquiring locks in callers. This does not fix threading
problems, because ReftableBatchRefUpdate already wraps the whole
transaction in a lock.
This also fixes a number of bugs in ReftableBatchRefUpdate:
* non-atomic updates should not bail on first failure
* isNameConflicting should also check for conflicts between names that
are added and removed in the BatchRefUpdate.

On changing a ref, the old SHA1 is not updated in the object => ref
mapping. This means search by object ID may still turn up a ref from
deeper within the stack. To fix this, check all refs produced by the
merged iterator against the merged reftables.

The flag enabling sideband-all is used in two places: in UploadPack
for advertisement and in the protocol parser to read it from the
request.
This leds to problems in distributed deployments where the two requests of
a fetch can go to different servers with different configurations.
Use the existing allowsidebandall to accept the sideband-all request
(and respond to it) and introduce a new "advertisesidebandall" to toggle
the advertising of the feature.

If the SubModuleWalk isn't closed its TreeWalk's ObjectReader won't
be closed. Re-loading the DirCache during an IndexDiff is not only
inefficient but could also give strange results if an external
process had modified the index in the meantime: file diffs would
be based on a "before" state, but submodule diffs on an "after"
state.

The object identifying packfiles to send them via packfile-uri contains
only the uri and the hash. This is the information that goes through the
wire. It would be useful to know also the size of those packfile, for
example to track how many bytes have been offloaded to HTTP.
Add size field the CachedPackUriProvider.PackInfo object.

* changes:
UploadPack: Create a method that propagates an exception as-is
UploadPack: Consolidate the sideband handling code to one place
UploadPack: Introduce ErrorWriter
Exception handling can be isolated from UploadPack. This makes it
possible to make the exception handler pluggable.

ErrorWriter writes an error message to the user. The implementation is
swapped once it detects that the client supports sideband. By default it
uses the protocol level ERR packet, which was introduced recently.
In total the error output is done in two different places;
UploadPack#upload and UploadPack#sendPack. These will be consolidated in
the next change.
