git-core follows HTTP redirects so JGit should also provide this.
Implement config setting http.followRedirects with possible values
"false" (= never), "true" (= always), and "initial" (only on GET, but
not on POST).[1]
We must do our own redirect handling and cannot rely on the support
that the underlying real connection may offer. At least the JDK's
HttpURLConnection has two features that get in the way:
* it does not allow cross-protocol redirects and thus fails on
http->https redirects (for instance, on Github).
* it translates a redirect after a POST to a GET unless the system
property "http.strictPostRedirect" is set to true. We don't want
to manipulate that system setting nor require it.
Additionally, git has its own rules about what redirects it accepts;[2]
for instance, it does not allow a redirect that adds query arguments.
We handle response codes 301, 302, 303, and 307 as per RFC 2616.[3]
On POST we do not handle 303, and we follow redirects only if
http.followRedirects == true.
Redirects are followed only a certain number of times. There are two
ways to control that limit:
* by default, the limit is given by the http.maxRedirects system
property that is also used by the JDK. If the system property is
not set, the default is 5. (This is much lower than the JDK default
of 20, but I don't see the value of following so many redirects.)
* this can be overwritten by a http.maxRedirects git config setting.
The JGit http.* git config settings are currently all global; JGit has
no support yet for URI-specific settings "http.<pattern>.name". Adding
support for that is well beyond the scope of this change.
Like git-core, we log every redirect attempt (LOG.info) so that users
may know about the redirection having occurred.
Extends the test framework to configure an AppServer with HTTPS support
so that we can test cloning via HTTPS and redirections involving HTTPS.

In 0bff481d45 to accurately use the two
limits it was necessary to move the LimitedInputStream out of the
PacketLineIn and further down to the PackParser. Unfortuantely this
didn't survive review, as a buggy test failed and the "fix" was to
drop this part of the code.
The maxPackSizeLimit should apply to the pack stream, not the pkt-line
framing used to send commands to control the ReceivePack instance. The
commands are controlled using a different limit. The failing test allowed
too many bytes in the pack and was only failing because it was including
the command framing. The correct fix for the test was simply to drop the
limit lower, to more closely match the actual pack size.

If the client sends a SHA-1 that the server does not recognize echo
this back to the client with an explicit error message instead of
the generic "internal server error".
This was always the intent of the implementation but it was being
dropped on smart HTTP due to the UploadPackServlet catching the
PackProtocolException, discarding the buffered message UploadPack
meant to send, and sending along a generic message instead.

The Repository class provides only one method to look up a ref by
name, getRef. If I request refs/heads/master and that ref does not
exist, getRef will look further in the search path:
ref/refs/heads/master
refs/heads/refs/heads/master
refs/remotes/refs/heads/master
This behavior is counterintuitive, needlessly inexpensive, and usually
not what the caller expects.
Allow callers to specify whether to use the search path by providing
two separate methods:
- exactRef, which looks up a ref when its exact name is known
- findRef, which looks for a ref along the search path
For backward compatibility, keep getRef as a deprecated synonym for
findRef.
This change introduces findRef and exactRef but does not update
callers outside tests to use them yet.

When during a PushOperation the server hits an exception different from
UnpackException the JGit server behaved wrong. That kind of exceptions
are handled so late that the connection is already released and the
information whether to talk sideband to the client is lost. In detail:
ReceivePack.receive() will call release() and that will reset the
capabilities. But later on the stack in ReceivePackServlet.doPost() it
is tried to send a response to client now with reset capabilities (no
sideband!).

Gitiles malfunctions in conjunction with jgit and guice
because of a recent Guice bug fix. Work around the problem
by parsing the URI directly, bypassing the unescaping
performed by the getPathInfo method.
This rest of this message is copied from
https://gerrit-review.googlesource.com/#/c/60820/ :
The fix for Guice issue #745[1] causes getPathInfo() within the
GuiceFilter to return decoded values, eliminating the difference
between "foo/bar" and "foo%2Fbar". This is in spec with the servlet
standard, whose javadoc for getPathInfo[2] states that the return
value be "decoded by the web container".
Work around this by extracting the path part directly from the request
URI, which is unmodified by the container. This is copying the Guice
behavior prior to the bugfix.

This change implements the http connection abstraction with the help of
org.apache.http.client.HttpClient. The default implementation used by
JGit is still the JDK HttpURLConnection. But now JGit users have the
possibility to switch completely to org.apache.httpclient. The reason
for this is that in certain (e.g. cloud) environments you are forced to
use the org.apache classes.

I have unfortunately introduced a few bugs in the native Git client
over the years. 1.7.5 is unable to send chunked requests correctly,
resulting in corrupt data at the server. Ban this client whenever
it uses chunked encoding with an error message.
Prior to some more recent versions, git push over HTTP failed to
report status information and error messages due to a race within
the client and its helper process. Check for these bad versions and
send errors as messages before the status report, enabling users
to see the failures on their terminal.

Error messages are typically short, below the 32 KiB in-memory buffer
size of the SmartOutputStream. When an error is queued up for sending
to a client and an exception is thrown up into the servlet handler we
discarded the message and sent nothing to the client, as the messages
were stuck inside of the SmartOutputStream buffer.
Hoist the creation of the output stream above the invocation of try
block of the service, and use close() in the few catch blocks that
assume there are buffered messages ready for transmission. This will
ensure errors from unpacking a stream in ReceivePack are sent off to
a client correctly, as previously these were causing no status report
to arrive at the client side as the data was stuck in the buffer.

Smart HTTP clients may request both multi_ack_detailed and no-done in
the same request to prevent the client from needing to send a "done"
line to the server in response to a server's "ACK %s ready".
For smart HTTP, this can save 1 full HTTP RPC in the fetch exchange,
improving overall latency when incrementally updating a client that
has not diverged very far from the remote repository.
Unfortuantely this capability cannot be enabled for the traditional
bi-directional connections. multi_ack_detailed has the client sending
more "have" lines at the same time that the server is creating the
"ACK %s ready" and writing out the PACK stream, resulting in some race
conditions and/or deadlock, depending on how the pipe buffers are
implemented. For very small updates, a server might actually be able
to send "ACK %s ready", then the PACK, and disconnect before the
client even finishes sending its first batch of "have" lines. This
may cause the client to fail with a broken pipe exception. To avoid
all of these potential problems, "no-done" is restricted only to the
smart HTTP variant of the protocol.

When the client is clearly making a smart HTTP request to our smart
HTTP server, return any errors like RepositoryNotFoundException or
ServiceNotEnabledException inside of the payload as a Git level ERR
message, rather than an HTTP error code.
This prevents the C Git command line client from retrying a failed
"$URL/info/refs?service=git-upload-pack" request without the smart
service URL, only to fail again with "403 Forbidden" when the dumb
as-is service has been disabled by the server configuration, or is
unavailable because the repository is not on the local filesystem.
