This provides a place to declare visibility restrictions and
transitive dependencies for each library.
Other targets should only declare dependencies on what they directly
use, making dependencies easier to maintain.
Trim the dependencies of org.eclipse.jgit:jgit to follow that rule.
It declares dependencies on Apache httpcomponents and the servlet
API but doesn't use them.

Set missingOverrideAnnotation=warning in Eclipse compiler preferences
which enables the warning:
The method <method> of type <type> should be tagged with @Override
since it actually overrides a superclass method
Justification for this warning is described in:
http://stackoverflow.com/a/94411/381622
Enabling this causes in excess of 1000 warnings across the entire
code-base. They are very easy to fix automatically with Eclipse's
"Quick Fix" tool.
Fix all of them except 2 which cause compilation failure when the
project is built with mvn; add TODO comments on those for further
investigation.

Gerrit Code Review.
Test build and execution is not implemented.
We prefer to consume maven_jar custom rule from bazlets repository,
for the same reasons as in the Gerrit project:
* Caching artifacts across different clones and projects
* Exposing source classifiers and neverlink artifact
TEST PLAN:
$ bazel build :all

TransportHttp sets 'Accept-Encoding: gzip' to allow the server to
compress HTTP responses. When fetching a loose object over HTTP, it
uses the following code to read the response:
InputStream in = openInputStream(c);
int len = c.getContentLength();
return new FileStream(in, len);
If the content is gzipped, openInputStream decompresses it and produces
the correct content for the object. Unfortunately the Content-Length
header contains the length of the compressed stream instead of the
actual content length. Use a length of -1 instead since we don't know
the actual length.
Loose objects are already compressed, so the gzip encoding typically
produces a longer compressed payload. The value from the Content-Length
is too high, producing EOFException: Short read of block.

Today there are plenty of modern build tool systems available in the
wild (in no particular order):
* http://bazel.io
* https://pantsbuild.github.io
* http://shakebuild.com
* https://ninja-build.org
* https://buckbuild.com
The attributes, that all these build tools have in common, are:
* reliable
* correct
* very fast
* reproducible
It must not always be the other build tool, this project is currently
using. Or, quoting Gerrit Code Review maintainer here:
"Friends, don't let friends use <the other build tool system>!"
This change is non-complete implementation of JGit build in Buck,
needed by Gerrit Code Review to replace its dependency with standlone
JGit cell. This is very useful when a developer is working on both
projects and is trying to integrate changes made in JGit in Gerrit.
The supported workflow is:
$ cd jgit
$ emacs <hack>
$ cd ../gerrit
$ buck build --config repositories.jgit=../jgit gerrit
With --config repositories.jgit=../jgit jgit cell is routed through
JGit development tree.
To build jgit, issue:
$ buck build //:jgit
[-] PROCESSING BUCK FILES...FINISHED 0,0s
Yes, you can't measure no-op build time, given that Buck daemon is
used.

When sending an error response due to ServiceNotAuthorizedException or
ServiceNotEnabledException, usually we send a default message. In the
ServiceNotEnabledException case, we use
403 Git access forbidden
except in a dumb-HTTP-specific filter where we use the servlet
container's default 403 response:
403 Forbidden
In the ServiceNotAuthorizedException case, we use the servlet
container's default 401 response:
401 Unauthorized
There is one exception: a ServiceNotEnabledException when handling a
smart HTTP /info/refs request uses the message from the exception:
403 Service not enabled
Be more consistent by always using the message from the exception. This
way, authors of a RepositoryResolver, UploadPackFactory, or
ReceivePackFactory can provide a more detailed message when appropriate.
The defaults are
401 Unauthorized
403 Service not enabled

Instead of dumping a full stack trace when a client sends an invalid
commit, record only a short line explaining the attempt:
Cannot receive Invalid commit c0ff33...: invalid author into /tmp/jgit.git
The text alone is sufficient to explain the problem and the stack
trace does not lend any additional useful information. ObjectChecker
is quite clear about its rejection cases.

Since git-core ff5effd (v1.7.12.1) the native wire protocol transmits
the server and client implementation and version strings using
capability "agent=git/1.7.12.1" or similar.
Support this in JGit and hang the implementation data off UploadPack
and ReceivePack. On HTTP transports default to the User-Agent HTTP
header until the client overrides this with the optional capability
string in the first line.
Extract the user agent string into a UserAgent class under transport
where it can be specified to a different value if the application's
build process has broken the Implementation-Version header in the
JGit package.

Compressing the response with gzip causes the stream to delay
flushing until gzip has seen the entire response message, or buffers
fill up and the compressed data has to be sent. This hides the
resolving progress monitor from the client, as well as any other
progress messages the server might be trying to send.
Disable compression in receive, matching what /git-upload-pack has.

Instead of a confusing 403 Forbidden error indicating the dumb file
service is disabled on this server, use 406 Not Acceptable to mean
the client sent a request for content (the plain info/refs file)
that this server does not want to provide.
The stock C Git client will report HTTP 406 error if it predates
1.6.6 or something goes wrong with the smart request and it tried
falling back to the dumb request. This may help to debug cases where
a broken proxy server exists between the client and the server and
has mangled a prior smart info/refs response.
Change-Id: Ic2b78ba9502e4bbdff7cc3ba1fd284cf7616412b
Enable streaming compression for any response that is bigger than
the 32 KiB buffer used by SmartOutputStream. This is useful on the
info/refs file which can have many branches and tags listed, and
is often bigger than 32 KiB, but also compresses by at least 50%.
Disable streaming compression on large git-upload-pack responses,
as these are usually highly compressed Git pack data. Trying to
compress these with gzip will only waste CPU time and additional
transfer space with the gzip wrapper. Small git-upload-pack data
is usually text based negotiation responses and can be squeezed
smaller with a little bit of CPU usage.

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.

This has no effect on Git clients, but for browsers, 403 Forbidden may
be more appropriate. 500 Internal Server Error implies that there is
a problem with the server, whereas ServiceMayNotContinueException is
specifically intended to cover cases where the server is functioning
correctly but has determined that the request may not proceed.

Include some behaviors that were not clear to me until I had used it a
few times.
Warn about broken behavior for capture groups that do not match. It
would be nice to support these, but even for the cases where it's
clear what the behavior should be, it would be infeasible to
implement.
For example, consider the second group of the regex "(/a)/b(/c)?"
matched against the path "/a/b". We might want getServletPath() to
return "/a/b" and getPathInfo() to return null, but this is hard to
implement: there's no easy way to say "the substring up to the point
where (/c) would have matched if it were in the string even though
it's not." And even if we could, it's not clear there is even a right
answer in the general case.
Moreover, ideally we could warn about such broken patterns at servlet
initialization time, rather than at runtime, but even answering the
question of whether there are capture groups that might not match
requires more customized regular expression parsing than we want to
embark on. Hence, the best we can do is document how it fails.

Implementations may want to send an error message to the user, which
doesn't really fit with any of the existing exception types.
ServiceMayNotContinueException, on the other hand, is documented as
always containing a user-visible error string, so use that.

message to the end user.

The fetch-pack/upload-pack stream usually has an LF at the
end of the first "want" line. Trim this when checking to
see if side-band or side-band-64k was used.
Perform the same trim for send-pack/receive-pack, as it is
harmless in this context to ignore an LF just before doing
an error report.
Change-Id: I6ef946bb6124fa72c52bd5320187eaac3ed906e7
When a client POSTs to /git-{upload,receive}-pack, the first line
includes their client capabilities. As soon as the C git client sends
side-band(-64k), it goes into a state where it chokes on data not sent
in a valid sideband channel.
GitSmartHttpTools.sendError() is called early in the request, likely
before a {Upload,Receive}Pack handler is assigned or, even so, before it
has read the request. In some cases we must read the first line manually
within sendError() to tell whether sideband is needed.
