Add a TransportConfigCallback parameter to JGit API commands, to allow
consumers of the JGit command API to perform custom Transport configuration
that would be otherwise difficult to anticipate & expose on the API command
builders.
My specific use-case is configuring additional properties on SshTransport
- I need to take over the SshSessionFactory used by the transport. Using
TransportConfigCallback I can simply do this (rather than reimplement the
API command classes):
public void configure(Transport tn) {
if (tn instanceof SshTransport) {
((SshTransport) tn).setSshSessionFactory(factoryProvider.get());
}
}
Adding an explicit setSshSessionFactory() method to the JGit command
classes would bloat the API. Also, creating the replacement
SshSessionFactory is unnecessary if the transport is not SSH, but the type
of the Transport is only known once the remote has been resolved and the
URI parsed - consequently it makes sense to perform this step in a
callback, where the transport instance can be inspected to determine if
it's of a relevant type.
A note about where this leaves the API - there are now 4 commands:
CloneCommand
PullCommand
FetchCommand
PushCommand
-that share 3 identical transport-related parameters:
timeout
credentialsProvider
transportConfigurator
I think there's potential for introducing an interface or val-object to
identify/encapsulate this repetition, which I'd be happy to do in a
subsequent commit.

Clients cache the set of advertised references at the start of a
negotiation, and keep replaying the same "want SHA1" list to the
server on each negotiation step. If another client pushes into
a branch and moves it by fast-forward, any request to obtain that
branch's prior SHA-1 is still valid, the commit is reachable from
the new position of the reference. Unfortunately the fast-forward
causes smart HTTP negotations to fail, as the server no longer is
advertising that prior SHA-1.
Instead of causing clients to fail out with a "want invalid" error
and forcing the end-user retry, possibly getting into a never ending
try-fail-retry race while other clients are pushing into the same
busy repository, allow the slightly stale want request so long as
it is still reachable.
C Git implemented this same change recently to fix races on the
smart HTTP protocol when the C Git git-http-backend is used.
The new RequestPolicy feature also allows server authors to make
an even more lenient configuration that exports any SHA-1 to the
client. This might be useful in certain settings where a server
has authenticated the client as the "repository owner" and wants
to allow them to grab any content from the server as a complete
unbroken history chain.
The new setAdvertisedRefs() method allows server authors to manually
fix the references that are advertised, possibly bypassing the
getAllRefs() call on the Repository object.

If the no-done capability was enabled on the connection, don't
queue up the state vector again once the ACK %s ready message
is observed from the remote. The pack will be following in this
response stream, so the state vector is no longer required.

The client's use of UnionInputStream was broken when combined with a
8192 byte buffer used by PackParser. A smart HTTP client connection
always pushes in the execute stateless RPC input stream after the
data stream has ended from the remote peer. At the end of the pack,
PackParser asked to fill a 8192 byte buffer, but if only e.g. 1000
bytes remained UnionInputStream went to the next stream and asked
it for input, which triggered a new RPC, and failed because there
was nothing pending in the request buffer.
Change UnionInputStream to only return what it consumed from a
single InputStream without invoking the next InputStream, just in
case that second InputStream happens to be one of these magical
ones that generates an RPC invocation.

The purpose of this commit is to prevent destruction of
submodules on checkout from a tree with a submodule to
another. For consistency we handle the reverse case too,
when we checkout a branch that has a submodule and the
submodule directory exists. And finally we ignore the
case where the submodule changes.
We do not update the submodules, we just try to ignore
them harder.

JGit currently identifies loose objects as 'corrupt' if they've been
deflated using a window size less than 32Kb, because the
isStandardFormat() function doesn't recognise the header
byte as a zlib header. This patch makes the method tolerant of
all valid window sizes (15-bit to 8-bit) - but doesn't sacrifice
it's accuracy in distingushing the standard loose-object format
from the experimental (now abandoned) format. It's based on a patch
which has been merged into C-Git master branch:
https://github.com/git/git/commit/7f684a2aff636f44a506
On memory constrained systems zlib may use a much smaller window
size - working on Agit, I found that Android uses a 4KB window;
giving a header byte of 0x48, not 0x78. Consequently all loose
objects generated by the Android platform appear 'corrupt' :(
It might appear that this patch changes isStandardFormat() to the
point where it could incorrectly identify the experimental format as
the standard one, but the two criteria (bitmask & checksum) can only
give a false result for an experimental object where both of the
following are true:
1) object size is exactly 8 bytes when uncompressed (bitmask)
2) [single-byte in-pack git type&size header] * 256
+ [1st byte of the following zlib header] % 31 = 0 (checksum)
As it happens, for all possible combinations of valid object type
(1-4) and window bits (0-7), the only time when the checksum will be
divisible by 31 is for 0x1838 - ie object type *1*, a Commit - which,
due the fields all Commit objects must contain, could never be as
small as 8 bytes in size.
Given this, the combination of the two criteria (bitmask & checksum)
always correctly determines the buffer format, and is more tolerant
than the previous version.

If the ResetCommand should reset to a invalid ref (e.g. HEAD in a repo
whithout a single commit) it was throwing an NPE. This is fixed now by
throwing a JGitInternalExcpeption. It would be nicer if we could throw
a InvalidRefException, but this would modify our API.

This can be useful when implementing garbage collection and there
are packs that should not be copied, such as huge packs that have
a sibling ".keep" file alongside of them.
Callers driving PackWriter need to initialize the list of packs not
to include objects from by passing each index to excludeObjects().
