Thomas Wolf 41b9159795 TagCommand: support signing annotated tags
Add the two config constants from C git that can switch on signing
of annotated tags. Add them to the GpgConfig, and implement actually
signing a tag in TagCommand.

The interactions between command line options for "git tag" and config
options is a bit murky in C git. There are two config settings for it:

* tag.gpgSign is the main option, if set to true, it kicks in if
  neither -s nor -u are given on the command line.
* tag.forceSignAnnotated signs only tags created via "git tag -m",
  but only if command-line option "-a" is not present. It applies
  even if tag.gpgSign is set explicitly to false.

Giving -s or -u on the command line also forces an annotated tag
since lightweight tags cannot be signed.

Thomas Wolf 5abd8a4feb Enable GpgSigner to also sign tags
Factor out a common ObjectBuilder as super class of CommitBuilder
and TagBuilder, and make the GpgSigner work on ObjectBuilder.

In order not to break API, add the new method for signing an
ObjectBuilder in a new interface GpgObjectSigner.

The signature for a tag is just tacked onto the end of the tag
message. The message of a signed tag must end in LF.

Petr Hrebejk 2fbbd6d890 Fix PackInvalidException when fetch and repack run concurrently
We are running several servers with jGit. We need to run repack from
time to time to keep the repos performant. I.e. after push we test how
many small packs are in the repo and when a threshold is reached we run
the repack.

After upgrading jGit version we've found that if someone does the clone
at the time repack is running the clone sometimes (not always) fails
because the repack removes .pack file used by the clone. Server
exception and client error attached.

I've tracked down the cause and it seems to be introduced between jGit
5.2 (which we upgraded from) and 5.3 and being caused by this commit:
Move throw of PackInvalidException outside the catch -
afef866a44

The problem is that when the throw was inside of the try block the last
catch block catched the exception and called openFailed(false) method.
It is true that it called it with invalidate = false, which is wrong.
The real problem though is that with the throw outside of the try block
the openFail is not called at all and the fields activeWindows and
activeCopyRawData are not set to 0. Which affects the later called tests
like: if (++activeCopyRawData == 1 && activeWindows == 0).

The fix for this is relatively simple keeping the throw outside of the
try block and still having the invalid field set to true. I did
exhaustive testing of the change running concurrent clones and pushes
indefinitely and with the patch applied it never fails while without the
patch it takes relatively short to get the error.

A SymbolicRef is added to the advertised refs for any symref in
capabilities whose target is an advertised ref; this may replace an
existing entry, such as HEAD.

When cloning, if any advertised HEAD is symbolic then use the target
rather than looking for an advertised ref with a matching objectId.

Add --symref option to LsRemote command.

Matthias Sohn fde7a271a4 Ensure that GC#deleteOrphans respects pack lock
If pack or index files are guarded by a pack lock (.keep file)
deleteOrphans() should not touch the respective files protected by the
lock file. Otherwise it may interfere with PackInserter concurrently
inserting a new pack file and its index.

The problem was caused by the following race.

All mentioned files are located in  "objects/pack/".
File endings relevant in "pack" dir:
  .pack
  .keep
  .idx
  .bitmap

When ReceivePack receives a pack file it executes the following steps:

ReceivePack.service():
  receivePackAndCheckConnectivity():
    receivePack():
      receive the pack
      parse the pack, returns packLock (.keep file)
      PackInserter.flush():
        write tmpPck file:  "insert_<random>.pack"
        write tmpIdx file:  "insert_<random>.idx"
        real pack name: "pack-<SHA1>.pack"
        real index name: "pack-<SHA1>.idx"
        atomic rename tmpPack to realPack
        atomic rename tmpIdx to tmpIdx
  execute commands
  unlock pack by removing .keep file
  trigger auto gc if enabled

When PackInserter.flush() renames the temporary pack to the final
"pack-xxx.pack" file  the temporary pack index file "insert_xxx.idx"
has no matching .pack file with the same base name for a short interval.
If deleteOrphans() ran during that interval it deduced the pack index
file was orphaned. Subsequently the missing pack index caused
MissingObjectExceptions since objects contained in the pack couldn't be
looked up anymore.

Thomas Wolf 9f3616dcb4 PacketLineIn: ensure that END != DELIM
Just allocate the two string objects directly. The previously used
new StringBuilder(0).toString() returns the same object for both END
and DELIM when run on Java 15, which breaks the wire protocol since
then END and DELIM cannot be distinguished anymore.

Thomas Wolf e84881ea6b Allow to resolve a conflict by checking out a file
DirCacheEditor unconditionally applied a PathEdit to all stages in the
index. This gives wrong results if one wants to check out a file from
some commit to resolve a conflict: JGit would update the working tree
file multiple times (once per stage), and set all stages to point to
the checked-out blob.

C git replaces the stages by the entry for the checked-out file.

To support this, add a DirCacheEntry.setStage() method so that
CheckoutCommand can force the stage to zero. In DirCacheEditor, keep
only the zero stage if the PathEdit re-set the stage.

Matthias Sohn f39f848c99 Document that setLastModified sets time of symlink target
Due to Java bug JDK-8220793 [1] Java cannot set timestamps of a symlink
but only of the symlink target. This bug was fixed in Java 13. Since we
don't have a use case to set the timestamp of the symlink itself simply
document the current behavior of setLastModified methods.

Alexa Panfil 4f3161d3cc Fix bug in PerformanceLogContext
PerformanceLogContext threw NullPointerException when multiple threads
tried to add an event to the PerformanceLogContext. The cause for this
is that the ThreadLocal was initialized only in the class constructor
for the first thread; for subsequent threads it was null.

To fix this initialize eventRecords for each thread.

Thomas Wolf d69fb4d4ac Revert "Client-side protocol V2 support for fetching"
This reverts commit f802f06e7f.

I had misunderstood how protocol V2 works. This implementation only
works if the negotiation during fetch is done in one round.

Fixing this is substantial work in BasePackFetchConnection. Basically
I think I'd have to change back negotiate to the V0 version, and have
a doFetch() that does

  if protocol V2
    doFetchV2()
  else
    doFetchV0()

with doFetchV0 the old code, and doFetchV2 completely new.

Plus there would need to be a HTTP test case requiring several
negotiation rounds.

This is a couple of days work at least, and I don't know when I will
have the time to revisit this. So although the rest of the code is
fine I prefer to back this out completely and not leave a only half
working implementation in the code for an indeterminate time.

Thomas Wolf f802f06e7f Client-side protocol V2 support for fetching
Make all transports request protocol V2 when fetching. Depending on
the transport, set the GIT_PROTOCOL environment variable (file and
ssh), pass the Git-Protocol header (http), or set the hidden
"\0version=2\0" (git anon). We'll fall back to V0 if the server
doesn't reply with a version 2 answer.

A user can control which protocol the client requests via the git
config protocol.version; if not set, JGit requests protocol V2 for
fetching. Pushing always uses protocol V0 still.

In the API, there is only a new Transport.openFetch() version that
takes a collection of RefSpecs plus additional patterns to construct
the Ref prefixes for the "ls-refs" command in protocol V2. If none
are given, the server will still advertise all refs, even in protocol
V2.

BasePackConnection.readAdvertisedRefs() handles falling back to
protocol V0. It newly returns true if V0 was used and the advertised
refs were read, and false if V2 is used and an explicit "ls-refs" is
needed. (This can't be done transparently inside readAdvertisedRefs()
because a "stateless RPC" transport like TransportHttp may need to
open a new connection for writing.)

BasePackFetchConnection implements the changes needed for the protocol
V2 "fetch" command (simplified ACK handling, delimiters, section
headers).

In TransportHttp, change readSmartHeaders() to also recognize the
"version 2" packet line as a valid smart server indication.

Adapt tests, and run all the HTTP tests not only with both HTTP
connection factories (JDK and Apache HttpClient) but also with both
protocol V0 and V2. Do the same for the SSH transport tests.

first submodule processed has a name and a path which do not match
SubmoduleWalk#getModuleName returned the module path instead of the
module name. In order to fix this SubmoduleWalk#getModuleName needs to
