In JGit 5.0, the FileTreeIterator was changed to skip ignored folders
by default. To catch tracked files inside ignored folders, the tree
walk needs to have a DirCacheIterator, and the FileTreeIterator has
to know about that DirCacheIterator via setDirCacheIterator(). (Or
the optimization has to be switched off explicitly via
setWalkIgnoredDirectories(true).)
Skipping ignored directories is an important optimization in some
cases, for instance in node.js/npm projects, where we'd otherwise
traverse the whole huge and deep hierarchy of the typically ignored
node_modules folder.
While all uses of WorkingTreeIterator in JGit had been adapted,
DiffFormatter was forgotten. To make it work correctly (again) also
for such cases, make it set up a WorkingTreeeIterator automatically,
and make sure the WorkingTreeSource can find such files, too. Also
pass the repository to the TreeWalks used inside the DiffFormatter
to pick up the correct attributes, filters, and line-ending settings.

Currently we're buffering the inflated bitmap entry in
BasePackBitmapIndex to optimize running time. However, this will use
lots of memory during the creation of the pack bitmap index file.
And change 161456, which rewrote the entire getBitmap method, increased
the fetch latency significantly.
This commit introduces getBitmapWithoutCaching method which is used in
the pack bitmap index file creation only and aims to save memory during
garbage collection and not increase fetch latency.

If a hunk does not apply at the position stated in the hunk header
try to determine its position using the old lines (context and
deleted lines).
This is still a far cry from a full git apply: it doesn't do binary
patches, it doesn't handle git's whitespace options, and it's perhaps
not the fastest on big patches. C git hashes the lines and uses these
hashes to speed up matching hunks (and to do its whitespace magic).

be raised if the destination folder does not exist. Instead of handling
this implicitly in the catch of IOException and then continuing to

create the destination folder. If any other IOException occurs, treat
it as an unexpected error and return FAILURE.
Subsequently, on the second attempt to move the temp file, if ANY kind
of IOException occurs, also consider this an unexpected error and

Move the classes depending on JSch to an OSGi fragment extending the

since moving them to another package would break API. Defer moving them

If the determination of the user home directory produces a Java File
object with an invalid path, spurious exceptions may occur at the
most inopportune moments anytime later. In the case in the linked bug
report, start-up of EGit failed, leading to numerous user-visible
problems in Eclipse.
So validate the return value of FS.userHomeImpl(). If converting that
File to a Path throws an exception, log the problem and fall back to
Java system property user.home. If that also is not valid, use null.
(A null user home directory is allowed by FS, and calling in Java
new File(null, "some_string") is fine and produces a File relative
to the current working directory.)

Currently the remapper class is only used in the construction of the
bitmap index file. And during the preparation of the file, we're only
getting bitmaps from the remapper when finding objects accessible from
a commit, so bitmap associated with each commit will only be fetched once
and thus the convertedBitmaps would hardly be read, which means that it's
not saving time.

Currently, the garbage collection is consistently failing for some large
repositories in the building bitmap phase, e.g.Linux-MSM project:
https://source.codeaurora.org/quic/la/kernel/msm-3.18
Historically, bitmap index creation happened in 3 phases:
1. Select the commits to which bitmaps should be attached.
2. Create all bitmaps for these commits, stored in uncompressed format
in the PackBitmapIndexBuilder.
3. Deltify the bitmaps and write them to disk.
We investigated the process. For phase 2 it's most efficient to create
bitmaps starting with oldest commit and moving to the newest commit,
because the newer commits are able to reuse the work for the old ones.
But for bitmap deltification in phase 3, it's better when a newer
commit's bitmap is the base, and the current disk format writes bitmaps
out for the newest commits first.
This change introduces a new collection to hold the deltified and
compressed representations of the bitmaps, keeping a smaller subset of
commits in the PackBitmapIndexBuilder to help make the bitmap index
creation more memory efficient.
And in this commit, we're setting DISTANCE_THRESHOLD to 0 in the
PackWriterBitmapPreparer, which means the garbage collection will not
have much behavoir change and will still use as much memory as before.

- Additional list of references we know client can be interested in
(e.g. list of open changes for Gerrit)

Revert commit 2323d7a. Using $0 in the shell command call results in
the command string being taken literally. That was introduced to fix
a problem with backslashes, but is actually not correct.
First, the problem with backslashes occurred only on Win32/Cygwin,
and has been properly fixed in commit 6f268f8.
Second, this is used only for hooks (which don't have backslashes in
their names) and filter commands from the git config, where the user
is responsible for properly quoting or escaping such that the commands
work.
Third, using $0 actually breaks correctly quoted filter commands
like in the bug report. The shell really takes the command literally,
and then doesn't find the command because of quotes.
So revert this change.
At the same time there's a related problem with hooks. If the path to
the hook contains blanks, runInShell() would also fail to find the
hook. In this case, the command doesn't come from user input but is
just a Java File object with an absolute path containing blanks. (Can
occur if core.hooksPath points to such a path with blanks, or if the
repository has such a path.)
The path to the hook as obtained from the file system must be quoted.
Add a test for a hook path with a blank.
This reverts commit 2323d7a1ef.

ReceiveCommand can have an error message. This is shown only for some
cases even if it's set. This change uses the error message if it's set,
and fallback to the default message if unset.

Commit 60cf85a4 corrected the handling of check-in for files where
the index version is non-normalized, i.e., contains CR-LF line endings.
However, it did so only for regular files, not executable files.

The recursive merge strategy builds a virtual ancestor merging
recursively the common bases (when more than one) between the
want-to-merge commits. While building this virtual ancestor, content
conflicts are ignored, but current code doesn't do so when a file is
removed.
This was spotted in [1], for example. Merging two commits to build the
virtual ancestor bumped into a conflict (modified in one side, deleted
in the other) that stopped the process.
Follow the "spec" and in case of conflict leave the unmerged content in
the index and working trees.

The error message for an Exception thrown by StartGenerator when given
both the TOPO flag and the TOPO_KEEP_BRANCH_TOGETHER flag mentions a
non-existent flag, TOPO_NON_INTERMIX. The error message was introduced
in commit e498d43.
Replace TOPO_NON_INTERMIX with TOPO_KEEP_BRANCH_TOGETHER in the error
message of an Exception thrown by the StartGenerator when the TOPO flag
is provided together with the TOPO_KEEP_BRANCH_TOGETHER flag.

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 producing 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, add a new RevSort option called TOPO_KEEP_BRANCH_TOGETHER
with a new topo sort algorithm in TopoNonIntermixGenerator. In the
Generator, when the last child of a commit has been produced, unpop
that commit so that it will be returned upon the subsequent call to
next(). 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.
Commit b5e764abd2 modified the existing
TopoSortGenerator to avoid mixing lines of history, but it was reverted
in e40c38ab08 because the new behavior
caused problems for EGit users. This motivated adding a new Generator
for the new behavior.

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
2. public
3. protected
4. private
5. abstract
6. static
7. final
8. transient
9. volatile
10. synchronized
11. native
12. strictfp
Not following this convention has no technical impact, but will reduce
the code's readability because most developers are used to the standard
order.
This was detected using SonarLint.
