Since 8ed59c5 ("Make TestRepository AutoCloseable", Jan 11, 2019) the
TestRepository class is auto-closeable, but instantiations of it were
not converted to use try-with-resource.
Converting to try-with-resource results, in several cases, in the
repository being closed twice because LocalDiskRepositoryTestCase has
logic to close created repositories in the tearDown method. This results
in several tests emitting a warning to the console:
close() called when useCnt is already zero
Change the default behavior of the createRepository method to not use
the auto-close logic in LocalDiskRepositoryTestCase, so that thy will
instead be closed (only once) using the AutoCloseable implementation.
Deprecate the method that has the autoClose parameter.

Using findRef instead of getRef makes it clearer that the caller wants
to search for the ref in the search path, instead of looking for a ref
that exactly matches the input.
This change introduces the new findRef method and deprecates getRef.
It updates Repository#findRef to use the new method, ensuring some
test coverage. Other callers will be updated in followup changes.
A nice side effect of introducing the new findRef method is that it is
final and based on firstExactRef, so implementers can focus on
implementing the latter efficiently and do not have to carefully write
custom path search code respecting SEARCH_PATH.

After cloning a repo with a submodule, non-recursively, JGit would
encounter in its TreeWalk in IndexDiff:
* first, a missing gitlink (in index & HEAD, not in working tree)
* second, the untracked folder (not in index and head, in working tree)
As a result, it would report the submodule as missing. Canonical git
reports a clean workspace.
The root cause of this is that the path of a gitlink "x" did
not compare equal to the path of a tree "x" in JGit.
Correct Paths.compare() to account for that. If two paths are otherwise
equal, then let gitlinks match both trees and files. Matching trees
solves the bug. Matching files is necessary to handle the case where
the gitlink directory was replaced by a file; see the new test case
IndexDiffSubmoduleTest.testSubmoduleReplacedByFile(). Comparisons of
unequal paths are left untouched, so the sort order is unchanged.
After the fix, another bug(?) in WorkingTreeIterator became apparent:
with core.dirNoGitLinks = true, it was no longer possible to overwrite
a gitlink in the index. This is now fixed in WorkingTreeIterator.
Add new test cases for the bug itself and for some related cases
(submodule directory deleted or replaced by a file) in
IndexDiffSubmoduleTest. Add a test for missing files in IndexDiffTest,
and adapt the PathsTest to test matching gitlinks.

This partially reverts commit a551b646: revert the changes in
RawParseUtils.lineMap(). Forcing all blobs containing a NUL byte
as a single line causes blame to produce useless results as soon
as it hits any version containing a NUL byte.
Doing binary detection at this level also has the problem that the
user cannot control it. Not by setting the text attribute nor in any
other way.
This came up in bug 541036, where a Java source inadvertently
contained NUL bytes in strings. Even fixing this by using escapes
"\000" will not fix JGit's blame for this file because the past
versions will still contain the NUL byte.
Native git can blame that file from bug 541036 fine.
Added new tests verifying that blaming a text file containing a NUL
byte produces sensible results.

fails if there are no common authentications between server and
client. The latter also tests that the ssh config setting is taken
into account at all.
And promptly the JGit sshd client didn't. Add a fix for this. It's
a tiny bit hacky: Apache MINA looks up a custom property set on a
hierarchy of "PropertyResolver"s starting with the session. On the
session itself this property can never be set since it's read
already in the session constructor before anyone had any chance
to set it. The next element in the resolver hierarchy is the sshd
SshClient, and so we set that property there. Since we use one
SshClient and one ClientSession per JGit SshdSession, this is OK.

a few bugs or idiosyncrasies that immediately would re-introduce bugs

Apache MINA sshd is not without quirks either, and I had to configure
and override more than I had expected. But at least it was all doable
in clean ways.
Apache MINA boasts support for Bouncy Castle, so in theory this should
open the way to using more ssh key algorithms, such as ed25519.

the core org.eclipse.jgit bundle. The tests re-use the ssh tests from

Move the bulk of the basic parsing and host entry handling into a
new class OpenSshConfigFile that has no dependencies on any concrete
ssh implementation. Make the existing OpenSshConfig use the new
parser.
Introduce a new class SshConstants collecting all the various ssh-
related string literals. Also use TreeMaps with a case-insensitive
key comparator instead of converting keys to uppercase. Add a test
to verify that keys are matched case-insensitively.
Most of the parsing code was simply moved, except that the new
parser supports looking up entries given host name, port, and user
name, and can thus handle more %-substitutions correctly. This
feature is not yet used and cannot be used with JSch since JSch
only has a ConfigRepository.getConfig(String) interface.
The split is still worth the trouble as it opens the way to using
another ssh client altogether. Apache MINA sshd, for instance,
resolves host entries giving host name, port, and user name.
(Apache MINA has a built-in ssh config handling, but that has
problems, too: its pattern matching is case-insensitive, and its
merging of host entries if several match is not the same as in
OpenSsh. But with this refactoring, it will be possible to plug in
OpenSshConfigFile into an Apache MINA sshd client without dragging
along JSch.)
One test case that doesn't make sense anymore has been removed. It
tested that repeatedly querying for a host entry returned the same
object. That is no longer true since the caching has been moved to
a deeper level.

failOnConflict=false, it would delete all conflicting files
from the working copy and just leave them missing. After
this commit, DirCacheCheckout overwrites conflicting files
with the merge tree.
This change in DirCacheCheckout causes "reset --hard" and
"revert --abort" to behave as expected (previously they
would simply delete conflicting files, now they will be
overwritten from the merge tree).

UploadPack.getPeerUserAgent() doesn't produce the expected results for
protocol v2 requests. In v2, the agent reported in the request (in an
"agent=" line) is not in the clientCapabilities but in a field on its
own. This makes getPeerUserAgent default to the transport user agent.
Making "agent" a shared property between protocol v0/v1 and v2 fixes the
problem, simplifies the function and harmonizes the implementation
between protocol versions.
In a follow up commit the "agent" will be identified on parsing time,
instead of taking it from the client capabilities.

In protocol v2, a command request can be followed by server options
(lines like "agent=<>" and "server-option=<>"), but current code
doesn't accept those lines.
Advertise the "server-option" capability, parse the lines and add
them to the request objects.
Other code in JGit can see this options and act accordingly via the
protocol v2 hooks.
This should not require any change in the client side.

Eclipse Photon supports separating sources and test sources.
There are no functional changes in the IDE, except for test source
folders having a different icon color.
Users of different IDEs than Eclipse are not affected, since the
attribute on the classpath entries will be ignored by their IDE.

Error Prone reports that the unsynchronized method skip overrides the
synchronized method in ByteArrayInputStream [1].
This is a test class, so we can just suppress the warning as recommended
in [1].
Note that the suppression causes a warning in Eclipse, because it doesn't
recognize the "UnsynchronizedOverridesSynchronized" as a valid value for
the @SuppressWarnings annotation [2].

In FetchV0Request, the fields "wantsIds" and "options" are called
"wantIds" and "clientCapabilities". Those names describe them better.
Rename FetchV2Request fields to follow fetch v0. This will make easier
to extract a superclass later.
Take also the chance to polish the javadoc.

In protocol v0/v1 pack negotiation, the first want line contains the
options the client wants in effect. This parsing is done in UploadPack
but it doesn't have any interaction with that class.
Move the code to its own class and package, mark the current one
as deprecated (it is public API) and add unit tests.
Take the chance to move the parsing code from the constructor to a
factory method, making the class a simple container of results.

files, but some could have been committed before those safeguards where
in place.
Add a check in DfsFsck to validate the .gitmodules files in the repo.

In order to validate .gitmodules files, we first need to find them
in the incoming pack.
Do it in the ObjectChecker stage. Check in the tree objects if they
point to a .gitmodules file and report the tree id and the .gitmodules
blob id.
This can be used later to check if the file is in the root of the
project and if the contents are good.
While we're here, make isMacHFSGit more accurate by detecting variants
of filenames that vary in case.

The tests were set up to expect an IllegalArgumentException when
the Config.getInt method was called with a section.key that has
not been set, or explicitly set to an empty string.
However, the IllegalArgumentException never gets thrown because
the getInt method returns the provided default ("1"), and because
there was no call to "fail" after getInt, the incorrect behavior
of the test was not noticed.
Remove the try/catch around getInt, and instead assert that the
expected default value is returned.

Support the deepen-since parameter when requested by a client using
protocol v2. This is done by:
- adding a DepthWalk.RevWalk#setDeepenSince method
- updating DepthGenerator to recognize when deepen-since is set
- recording in DepthWalk.Commit whether a commit is a boundary commit
Existing users of DepthWalk such as UploadPack previously recognized
boundary commits by comparing their depths against the threshold, not
tracking whether any parents were truly excluded. This behavior is
preserved - UploadPack considers a commit as boundary if its depth is
equal to the threshold *or* a parent was excluded (whether by depth or
by deepen-since).

The BufferedWriter is opened in a try-with-resource and thus will be
automatically closed.
Presumably the close was added to make sure it is closed before the
subsequent test statements are executed. Instead of explicitly closing
it, let the try-with-resource automatically close it, and move the
subsequent statements out of the try-block.
