This test was never being run. Since it was introduced it was
named "notest.." which meant it didn't run with JUnit3, and
since it is not annotated @Test it also doesn't run with JUnit4.
When compiling with Bazel 0.6.0, error-prone raises an error
that the public method is not annotated with @Ignore or @Test.
Given that the test has never been run anyway, we can just
remove it.

Git has a rather elaborate mechanism to specify HTTP configuration
options per URL, based on pattern matching the URL against "http"
subsection names.[1] The URLs used for this matching are always the
original URLs; redirected URLs do not participate.
* Scheme and host must match exactly case-insensitively.
* An optional user name must match exactly.
* Ports must match exactly after default ports have been filled in.
* The path of a subsection, if any, must match a segment prefix of
the path of the URL.
* Matches with user name take precedence over equal-length path
matches without, but longer path matches are preferred over
shorter matches with user name.
Implement this for JGit. Factor out the HttpConfig from TransportHttp
and implement the matching and override mechanism.
The set of supported settings is still the same; JGit currently
supports only followRedirects, postBuffer, and sslVerify, plus the
JGit-specific maxRedirects key.
Add tests for path normalization and prefix matching only on segment
separators, and use the new mechanism in SmartClientSmartServerSslTest
to disable sslVerify selectively for only the test server URLs.
Compare also bug 374703 and bug 465492. With this commit it would be
possible to set sslVerify to false for only the git server using a
self-signed certificate instead of having to switch it off globally
via http.sslVerify.

With atomic ref updates using packed refs, JGit did not fire a
RefsChangedEvent. This resulted in a user-visible regression in
EGit: the UI would not update after a "Fetch from upstream...".
Presumably it would also make Gerrit miss out on ref changes?
Strengthen the BatchRefUpdateTest by also asserting the expected
number of RefsChangedEvents, and ensure modCnt is incremented in
RefDirectory.commitPackedRefs() when refs really changed (as opposed
to some internal housekeeping operation, such as packing loose refs).

An application can choose to invoke setAdvertisedRefs multiple times,
for example several AdvertiseRefsHook installed in a chain. Each of
these invocations populates the advertisedHaves collection with the
unique set of ObjectIds.
This can lead to a server over-advertising with ".have" lines if the
first hook pushes in a lot of references, and the second hook filters
this to a subset. ReceivePack will advertise the unique objects from
the first hook using ".have" lines, which may lead to a huge
advertisement sent to the client.
This can also contribute to a very slow connectivity check after the
pack is parsed as ReceivePack calls markUninteresting on every commit
in advertisedHaves. This may require expanding a lot of subtrees to
mark all trees as uninteresting as well. On a very big repository
this can lead to a many-second stall.
Clear the advertisedHaves collection any time the refs are updated.
Add a test to verify the correct set of objects was sent.

If a ReftableConfig has been supplied by the caller, write out a
reftable as a sibling of the the GC pack, alongside the heads.
To bootstrap from a non-reftable system, the refs are read from the
DfsRefDatabase if no GC reftables are present. Its assumed the
references are fully current, and do not need to be merged with any
other reftables. Any non-GC reftables will be pruned at the end of
the GC cycle, just like any packs that were replaced.
If a GC reftable is present, all existing reftables are compacted, and
references from DfsRefDatabase are only used to seed the packer. Its
assumed these are consistent with each other.

Some tests call out to external cgit. Those tests all failed for me
locally on Mac. Turned out that the reason was that the system git
config used by the git in the bazel run contained paths with ~/ but
somehow $HOME was not set. As a result the external git returned
with exit code 128.
Fix this by passing along $HOME explicitly. Also improve assertions
to make sure we do get the stderr of the external command in the
test log.
I hadn't noticed that until now because apparently the maven build
does pass along $HOME.

Other than I expected save actions are run globally on edited files -
and not only on edited code lines only.
Hence revert the save action "Convert control statement bodies to
blocks" which would affect a large number of code lines not affected by
the change editing some small part of a class. This would generate a
large number of changes which may lead to many unnecessary conflicts.
Total number of affected lines across jgit would be around 10k lines.
Also revert "Remove unused imports" since it erroneously removes imports
of some annotations needed by pgm classes using args4j.

Some repositories can have a policy that do not accept certain blobs. To
check if the incoming pack file contains such blobs, ObjectChecker can
be used. However, this ObjectChecker is not called by PackParser if the
blob is stored as a whole. This is because the object can be so large
that it doesn't fit in memory.
This change introduces BlobObjectChecker. This interface takes chunks of
a blob instead of the entire object. ObjectChecker can optionally return
a BlobObjectChecker. This won't change existing ObjectChecker
implementation; existing implementation continues to receive deltified
blob objects only.

Path pattern matching for attribute rules is different than matching
for excluded files.
The first difference concerns patterns without slashes. For
gitattributes those must match on the last component only, not on
any earlier segment. This is true also for directory-only patterns.
The second difference concerns directory-only patterns. Those also
must not match on a prefix or segment except the last one. They do
not apply recursively to all files beneath.
And third, matches only on a prefix must match for gitattributes
only if the last matcher was "/**".
Add a new parameter for such path matching to IMatcher.matches() and
pass it through as appropriate (false for gitignore, true for
gitattributes). As far as gitignore is concerned, there is no change.
New tests have been added, and some existing attribute matching tests
have been fixed since they operated on wrong assumptions.

These tests verify that JGit matches the same as C git, for
both attribute matching (.gitattributes) and file exclusion matching
(.gitignore). These tests work by setting up a test repository and
test rules, and then determine excluded files or attributes both with
JGit and with the native C git, and then compare the results.
For .gitignore tests, we run
git ls-files --ignored --exclude-standard -o
and for attribute tests we use
git check-attr --stdin --all
and pass the list of all files in the repository via stdin.

Jsch doesn't know about token substitutions at all. By doing the

make Jsch support most of these tokens.
%i is not handled at all as Java has no concept of a "user ID".

Ensure the Jsch instance used knows about ~/.ssh/config. This
enables Jsch to honor more user configurations (see
com.jcraft.jsch.Session.applyConfig()), in particular also the
UserKnownHostsFile configuration, or additional identities given
via multiple IdentityFile entries.
Turn JGit's OpenSshConfig into a full parser that can be a
Jsch-compliant ConfigRepository. This avoids a few bugs
in Jsch's OpenSSHConfig and keeps the JGit-facing interface
unchanged. At the same time we can supply a JGit OpenSshConfig
instance as a ConfigRepository to Jsch. And since they'll both
work from the same object, we can also be sure that the parsing
behavior is identical.
The parser does not handle the "Match" and "Include" keys, and it
doesn't do %-token substitutions (yet).
Note that Jsch doesn't handle multi-valued UserKnownHostFile
entries as known by modern OpenSSH.[1]

Add an update_index to every reference in a reftable, storing the
exact transaction that last modified the reference. This is necessary
to fix some merge race conditions.
Consider updates at T1, T3 are present in two reftables. Compacting
these will create a table with range [T1,T3]. If T2 arrives during
or after the compaction its impossible for readers to know how to
merge the [T1,T3] table with the T2 table.
With an explicit update_index per reference, MergedReftable is able to
individually sort each reference, merging individual entries at T3
from [T1,T3] ahead of identically named entries appearing in T2.

Currently there is no way to determine the precise changes done
to the working tree by a JGit command. Only the CheckoutCommand
actually provides access to the lists of modified, deleted, and
to-be-deleted files, but those lists may be inaccurate (since they
are determined up-front before the working tree is modified) if
the actual checkout then fails halfway through. Moreover, other
JGit commands that modify the working tree do not offer any way to
figure out which files were changed.
This poses problems for EGit, which may need to refresh parts of the
Eclipse workspace when JGit has done java.io file operations.
Provide the foundations for better file change tracking: the working
tree is modified exclusively in DirCacheCheckout. Make it emit a new
type of RepositoryEvent that lists all files that were modified or
deleted, even if the checkout failed halfway through. We update the
'updated' and 'removed' lists determined up-front in case of file
system problems to reflect the actual state of changes made.
EGit thus can register a listener for these events and then knows
exactly which parts of the Eclipse workspace may need to be refreshed.
Two commands manage checking out individual DirCacheEntries themselves:
checkout specific paths, and applying a stash with untracked files.
Make those two also emit such a new WorkingTreeModifiedEvent.
Furthermore, merges may modify files, and clean, rm, and stash create
may delete files.

When creating a new PackFile instance it is specified whether this pack
has an associated bitmap index file or not. This information is cached
and the public method getBitmapIndex() will always assume a bitmap index
file must exist if the cached data tells so. But it may happen that the
packfiles are repacked during a gc in a different process causing the
packfile, bitmap-index and index file to be deleted. Since JGit still
has an open FileHandle on the packfile this file is not really deleted
and can still be accessed. But index and bitmap index file are deleted.
Fix getBitmapIndex() to invalidate the cached packfile instance if such
a situation occurs.
This problem showed up when a gerrit server was serving repositories
which where garbage collected with native git regularly. Fetch and
clone commands for certain repositories failed permanently after a
native git gc had deleted old bitmap index files.

Arguably, binary data should not make it to
