Markus Duft 94bcde663c LFS: Add remote download to SmudgeFilter
Transfer data in chunks of 8k Transferring data byte per byte is slow,
running checkout with CleanFilter on a 2.9MB file takes 20 seconds.
Using a buffer of 8k shrinks this time to 70ms.

Also register the filter commands in a way that the native GIT LFS can
be used alongside with JGit.

Implements auto-discovery of LFS server URL when cloning from a Gerrit
LFS server.

David Pursehouse 9bebb1eae7 RepoCommand: Don't leave Git open
When the command is run on a non-bare repository, an instance of
Git is created to execute the commit, and is left open when the
command has finished.

Refactor to not use a class scope Git instance, and make sure it
gets closed before returning.

Thomas Wolf 185e53bce4 Fix ssh host name handling for Jsch
If we give Jsch access to the ssh config file, we must _not_ resolve
the host name from the alias. Instead we must give the alias (i.e.,
the host name as is in the URI) to Jsch, so that it finds the same
ssh config entry.

Otherwise if the hostname in the URI, which is taken as an alias in
ssh config ("Host" line), is unequal to the "Hostname" line, and
there happens to be another ssh config entry with that translated
host name as alias, Jsch will pick up that second entry, and we end
up with a strange mixture of both.

Add tests for this case.

David Pursehouse f527d4548f InitCommand: Don't leave Repository open after Git is closed
The InitCommand returns a Git that is instantiated with the newly
created Repository, but the Repository is not closed with the Git
resulting in resource leaks.

Create the Git with `closeRepo` set to true, such that the Repository
is also closed when the Git is closed.

Adjust the tests to use try-with-resource on the Git instance.

Terry Parker 9530c10192 Add a minimum negotiation feature for fetch
Android an Chrome have several repos with >300k refs. We sometimes see
negotiations of >100k rounds. This change provides a "minimal negotiation"
feature on the client side that limits how many "have" lines the client
sends. The client extracts the current SHA-1 values for the refs in its
wants set, and terminates negotiation early when all of those values have
been sent as haves. If a new branch is being fetched then that set will
be empty and the client will terminate after current default minimum
of two rounds.

This feature is gated behind a "fetch.useminimalnegotiation" configuration
flag, which defaults to false.

Christian Halstrick 4d5231f001 Fix CleanCommand not to throw FileNotFoundExceptions
When CleanCommand is collecting the files and folders to be deleted
it may happen that the list of directories contains obsolete entries.
E.g. a folder and its parent folder may be in the list. Only the
parent folder would be sufficient.

This was a reason for hitting FileNotFoundExceptions when finally
trying to delete the files and folders. Improve CleanCommand
to ignore files to be deleted which are already gone.

Hector Caballero 93654f75a2 GC: Remove empty references folders
After packaging references, the folders containing these references are
not deleted. In a busy repository, this causes operations to slow down
as traversing the references tree becomes longer.

Delete empty reference folders after the loose references have been
packed.
To avoid deleting a folder that was just created by another concurrent
operation, only delete folders that were not modified in the last 30
seconds.

David Ostrovsky ab1b97234d Bazel: Support building with Java 9
Bazel@HEAD supports Java 9.

The current code has one single issue with Java 9 compliance: the usage
of javax.xml.bind.DatatypeConverter class for printHexBinary() method.
This class is not available on Java 9. One alternative is to use guava
library. Something similar was done here: [1]. But unlike the case with
checkstyle library, JGit currently doesn't use guava. Instead, we add
java.xml.bind module with --add-modules compiler option.

To build (or test) with Java 9, build custom bazel version and issue:

  $ bazel --host_javabase=/usr/lib64/jvm/java-9-openjdk build \
    --javacopt='--release 9' \
    --java_toolchain=@bazel_tools//tools/jdk:toolchain_jdk9 :all

The Java 9 support is backwards compatible.

David Turner be2a8ed63b Basic submodule merge handling
This doesn't handle the really hard thing, which is merging spurious
conflicts inside .gitmodules files.  That's OK: git.git doesn't
either.  Users can resolve the conflict themselves and then commit
the merge.

Previously, jgit would crash when attempting to merge conflicting
submodule changes.  Even if there was no conflict, after a merge which
adds submodules, the repository would have been missing empty
directories for newly-added submodules.

This patch fixes the crash, and adds the empty directories where
necessary. It ensures that the index is in a conflicted state when
submodule changes conflict.

Thomas Wolf 9ac415aa95 Fix index blob for merges with CRLF translations
Commit fc7d407 corrected line endings for working tree files resulting
from merges when CRLF translations are to be done. However, that also
resulted in the file content being put as-is into the index, which is
wrong. The index must contain the file content with reverse CRLF
translations applied.

With core.autocrlf=true, the working tree file should have CR-LF, but
the index blob must still contain only LF.

Fix this oversight and apply the inverse translation when updating the
index, similar to what is done in AddCommand.

Thomas Wolf bea3b46678 Revert handling of ssh IdentityFile to pre-4.9 behavior
Jsch caches keys (aka identities) specified in ~/.ssh/config via
IndentityFile only for the current Jsch Session. This results in
multiple password prompts for successive sessions.

Do the handling of IdentityFile exclusively in JGit, as it was before
4.9. JGit uses different Jsch instances per host and caches the
IdentityFile there, allowing it to be re-used in different sessions
for the same host.

* Add comments to explain this.
* Move the JschBugFixingConfig from OpenSshConfig to
  JschConfigSessionFactory to have all these Jsch work-arounds
  in one place.
* Make that config hide the IdentityFile config from Jsch to avoid
  that Jsch overrides the JGit behavior.
