AdvertiseRefsHook is used to limit the visibility of the refs in Gerrit.
If this hook is not called, then all refs are treated as visible,
causing the server to serve commits reachable from branches the client
should not be able to access, if asked to via a request naming a guessed
object id.
This bug was introduced in v2.0.0.201206130900-r~123 (Modify refs in
UploadPack/ReceivePack using a hook interface, 2012-02-08). Stateful
bidirectional transports are not affected.
Fix it by moving the AdvertiseRefsHook call to
getAdvertisedOrDefaultRefs, ensuring the hook is called in all cases.
[jn: backported to stable-4.5 by splitting out tests and the protocol v2
specific parts]

SpotBugs [1] is the spiritual successor of FindBugs, carrying on from
the point where it left off with support of its community.
This is a backport of [1] which originally did the replacement on the
master branch. This change updates to the current latest version, so
that we can get the benefit of its checks when pushing changes to the
stable branches.

A .gitmodules file can include a submodule without a path to configure
the URL for a submodule that is only present on other branches.
A .gitmodules file can include a submodule with no URL and no path to
reserve the name for a submodule that existed in earlier history but
is not available from any URL any more.
"git fsck" permits both of these cases. Permit them in JGit as well
(instead of throwing NullPointerException).

The text "<tree, blob>" with angle brackets should not be used in javadoc
since it is interpreted as an HTML tag and then rejected since it's not a
valid HTML tag. Wrap the text in a @literal tag.
Also add a missing space.

The main concern are submodule urls starting with '-' that could pass as
options to an unguarded tool.
Pass through the parser the ids of blobs identified as .gitmodules
files in the ObjectChecker. Load the blobs and parse/validate them
in SubmoduleValidator.

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.

In C git versions before 2.19.1, the submodule is fetched by running
"git clone <uri> <path>". A URI starting with "-" would be interpreted
as an option, causing security problems. See CVE-2018-17456.
Refuse to add submodules with URIs, names or paths starting with "-",
that could be confused with command line arguments.

Check in #sendError method if the response was committed already.
If yes we cannot set response status or send an error message, last
resort is to close the outputstream.
If the response wasn't yet committed first reset the response before
using writer to send the error message to the client since mixing STREAM
and WRITE mode (mixing asynchronous and blocking I/O) is illegal in
servlet 3.1.

When buffer was written not only call AsyncContext#complete() but also
return from the ObjectDownloadListener#onWritePossible(). This avoids
endless loop after upgrading from Jetty 9.3.x to 9.4.x lines.
In Jetty example implementation:[1] the return statemnt is also used:
// If we are at EOF then complete
if (len < 0)
{
async.complete();
return;
}

(cherry picked from commit d9e767b431)
Signed-off-by: David Pursehouse <david.pursehouse@gmail.com>
FS_POSIX.createNewFile(File) failed to properly implement atomic file
creation on NFS using the algorithm [1]:
- name of the hard link must be unique to prevent that two processes
using different NFS clients try to create the same link. This would
render nlink useless to detect if there was a race.
- the hard link must be retained for the lifetime of the file since we
don't know when the state of the involved NFS clients will be
synchronized. This depends on NFS configuration options.
To fix these issues we need to change the signature of createNewFile
which would break API. Hence deprecate the old method
FS.createNewFile(File) and add a new method createNewFileAtomic(File).
The new method returns a LockToken which needs to be retained by the
caller (LockFile) until all involved NFS clients synchronized their
state. Since we don't know when the NFS caches are synchronized we need
to retain the token until the corresponding file is no longer needed.
The LockToken must be closed after the LockFile using it has been
committed or unlocked. On Posix, if core.supportsAtomicCreateNewFile =
false this will delete the hard link which guarded the atomic creation
of the file. When acquiring the lock fails ensure that the hard link is
removed.

When core.supportsAtomicCreateNewFile was set to false and the
repository was located on a filesystem which doesn't support the file
attribute "unix:nlink" then FS_POSIX#createNewFile may report an error
even if everything was ok. Modify FS_POSIX#createNewFile to silently
ignore this situation. An example of such a filesystem is sshfs where
reading "unix:nlink" always returns 1 (instead of throwing a exception).

I88304d34c and Ia555bce00 modified the way errors are handled when
trying to delete non-empty reference folders. Before, this error was
silently ignored as it was considered an expected output. Now, every
failed folder delete is logged which can be noisy.
Ignore the DirectoryNotEmptyException but log any other error avoiding
deletion of an eligible folder.

Recent Bazel versions support the hyphen character in external
repository names. On the Gerrit project, the repository names
were harmonized to consistently use hyphen.
As a side effect, it is no longer possible to build jgit from source
in the gerrit tree, due to the different repository names.
Rename the dependencies to use hyphens, consistent with gerrit.

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.
