Option ignoreConflicts is used when a caller want to create a virtual

ResolveMerger should populate only stage 0 for entries with merge
conflicts as if there is no conflict. Current implementation breaks
this contract for cases when gitlink revision is ambiguous.
Therefore, always select 'ours' when we merge in ignoreConflicts mode.
This will satisfy the contract contract, so recursive merge can
succeed, however it is an arbitrary decision, so it is not guaranteed
to select best GITLINK in all cases.
GITLINK merging is a special case of recursive merge because of
limitations of GITLINK type of entry. It can't contain more than 1 sha-1
so jgit can't write merge conflicts in place like it can with a blob.
Ideally we could signal the conflict with a special value (like
'0000...'), but that must be supported by all tooling (git fsck, c-git)."

FS: use binary search to determine filesystem timestamp resolution
Previous code used a minimum granularity of 1 microsecond and would
iterate 233 times on a system where the resolution is 1 second (for

New code uses a binary search between the maximum we care about (2
seconds) and zero, with a minimum granularity of also 1 microsecond.
This takes at most 19 iterations (guaranteed). For a file system with 1
second resolution, it takes 4 iterations (1s, 0.5s, 0.8s, 0.9s). With
an up-front check at 1 microsecond and at 1 millisecond this performs
equally well as the old code on file systems with a fine resolution.

Keep line endings for text files committed with CR/LF on text=auto
Git never converts line endings if the version in the repository is a
text file with CR/LF and text=auto. See [1]: "When the file has been
committed with CRLF, no conversion is done."
Because the sentence just before is about converting line endings on
check-in, I had understood that in commit 60cf85a [2] to mean that no
conversion on check-in was to be done. However, as bug 565048 and a
code inspection of the C git code showed it really means no conversion
is done on check-in *or check-out*.
If the text attribute is not set but core.autocrlf = true, this is
the same as text=auto eol=crlf. C git does not convert on check-out
even on text=auto eol=lf if the index version is a text file with
CR/LF.
For check-in, one has to look at the intended target, which is done
in WorkingTreeIterator since commit 60cf85a. For check-out, it can
be done by looking at the source and can thus be done in the
AutoLFOutputStream.
Additionally, provide a constructor for AutoLFInputStream to do
the same; for cases where the equivalent of a check-out is done via
an input stream obtained from a blob. (EGit does that in its
GitBlobStorage for the Eclipse compare framework; it's more efficient
than using a TemporaryBuffer and DirCacheCheckout.getContent(), and
it avoids the need for a temporary file.)
Adapt existing tests, and add new checkout and merge tests to verify
the resulting files have the correct line endings.
EGit's GitBlobStorage will need to call the new version of
EolStreamTypeUtil.wrapInputStream().
The WindowCache is configured statically with a default
WindowCacheConfig. The default config says (for backwards
compatibility reasons) to publish the MBean. As a result,
the MBean always gets published.
By delaying the MBean registration until the first call to
getInstance() or get(PackFile, long) we can avoid the forced
registration and do it only if not re-configured in the meantime
not to publish the bean. (As is done by Egit, to avoid a very
early costly access to the user and system config during plug-in
activation.)

DirCache: support index V4
Index format version 4 was introduced in C git in 2012. It's about
time that JGit can deal with it.
Version 4 added prefix path compression. Instead of writing the full
path for each index entry to disk, only the difference to the previous
entry's path is written: a variable-encoded int telling how many bytes
to remove from the previous entry's path to get the common prefix,
followed by the new suffix.
Also, cache entries in a version 4 index are not padded anymore.
Internally, version 3 and version 4 index entries are identical; it's
only the stored format that changes.
Implement this path compression, and make sure we write an index file
that we read previously in the same format. (Only changing from version
2 to version 3 if there are extended flags.)

FS_POSIX: avoid prompt to install the XCode tools on OS X
OS X ships with a default /usr/bin/git that is just a wrapper that
at run-time delegates to the selected XCode toolchain, and that
prompts the user to install the XCode command line tools if not
already installed.
This is annoying for people who don't want to do so, since they'll
be prompted on each Eclipse start. Also, since on OS X the $PATH for
applications started via the GUI is not the same as the $PATH as set
via the shell profile, just using /usr/bin/git (which will normally
be found when JGit runs inside Eclipse) may give slightly surprising
results if the user has installed a non-Apple git and changed his
$PATH in the shell such that the non-Apple git is used in the shell.
(For instance by placing /usr/local/bin earlier on the path.) Eclipse
and the shell will use different git executables, and thus different
git system configs.
Therefore, try to find git via bash --login -c 'which git' not only
if we couldn't find it on $PATH but also if we found the default git
/usr/bin/git. If that finds some other git, use that. If the bash
approach also finds /usr/bin/git, double check via xcode-select -p
that an XCode git is present. If not, assume there is no git installed,

DiffFormatter: correctly deal with tracked files in ignored folders
In JGit 5.0, the FileTreeIterator was changed to skip ignored folders

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

Improve error message when receive.maxCommandBytes is exceeded
The message "Too many commands" implies there is a hard limit on the
number of commands, which isn't the case. The limit is on the total
size of the received data, as explained in change I84317d396 which
introduced the configuration setting receive.maxCommandBytes:
shorter reference names allow for more commands, longer reference
names permit fewer commands per batch.
Change the message to:
Commands size exceeds limit defined in receive.maxCommandBytes

LfsConnectionFactory#getLfsUrl: Fix unconditional break in for-loop
When iterating over the remote URLs to find one that matches "origin",
it always exits after the first iteration whether it has found the
remote or not. The break should be inside the conditional block so
that it exits when "origin" is found, otherwise continues to iterate
over the remaining remote URLs.
Found by Sonar Lint.

DiffFormatterTest: Add a test to confirm the default rename detection settings
Add a test that confirms:
- No rename detector is initialized by default
- Rename detector is initialized after calling setDetectRenames(true)
- Rename limit and rename score have the default values 400 and
60, respectively. Note that there are no constants for these values
so the test hard codes them.

PackBitmapIndex: Not buffer inflated bitmap during bitmap creation.
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.
