TransportHttp: shared SSLContext during fetch or push
TransportHttp makes several HTTP requests. The SSLContext and socket
factory must be shared over these requests, otherwise authentication
information may not be propagated correctly from one request to the
next. This is important for authentication mechanisms that rely on
client-side state, like NEGOTIATE (either NTLM, if the underlying HTTP
library supports it, or Kerberos). In particular, SPNEGO cannot
authenticate on a POST request; the authentication must come from the
initial GET request, which implies that the POST request must use the
same SSLContext and socket factory that was used for the GET.
Change the way HTTPS connections are configured. Introduce the concept
of a GitSession, which is a client-side HTTP session over several HTTPS
requests. TransportHttp creates such a session and uses it to configure
all HTTP requests during that session (fetch or push). This gives a way
to abstract away the differences between JDK and Apache HTTP connections
and to configure SSL setup outside.
A GitSession can maintain state and thus give all HTTP requests in a
session the same socket factory.
Introduce an extension interface HttpConnectionFactory2 that adds a
method to obtain a new GitSession. Implement this for both existing
HTTP connection factories. Change TransportHttp to use the new
GitSession to configure HTTP connections.
The old methods for disabling SSL verification still exist to support
possibly external connection and connection factory implementations
that do not make use of the new GitSession yet.

SSLContext.getInstance("TLS") by default behaves differently on IBM
JDK than on Oracle or OpenJDK.[1] On IBM JDK one gets sockets that
have only TLSv1 enabled, which makes HTTPS connections fail since most
servers refuse this old protocol version. On Oracle JDK/OpenJDK, one
gets sockets with all available protocol versions enabled.
Explicitly enable all available TLS protocol versions to make
HTTPS connections work also on IBM JDK.

Factor out the test parameterization to use both connection factories
into a common super class and use it in more tests.
This made HttpClientTests.testV2HttpSubsequentResponse() fail for
Apache HTTP. The test used the pattern
- create POST connection
- setDoOutput(true)
- connect()
- write output stream
- get & read input stream
This pattern is never used in JGit, which actually calls connect() only
in one case in LFS, and that's on a HEAD request.
The above pattern works on JDK, but fails on Apache HTTP because with
Apache HTTP a connect() actually executes the full request including
writing the entity. To work with Apache HTTP, the pattern would need
to be
- create POST connection
- setDoOutput(true)
- write output stream
- connect()
- get & read input stream
which is fine for both. JDK connects implicitly in getOutputStream()
and treats the later explicit connect() as a no-op, and Apache works
because the entity is written when connect() is called.
Because JDK connects implicitly on getOutputStream(), the following
pattern also works with JDK:
- create POST connection
- setDoOutput(true)
- write output stream
- get & read input stream
Support this with Apache HTTP too: let getInputStream() execute
the request if it wasn't executed already.
Remove explicit connect() calls from test code, since JGit doesn't do
those either.

Add a method to get all values of HTTP header defined as list
According to RFC 2616 [1] header field names are case insensitive.
Header fields defined as a comma separated list can have multiple header
fields with the same field name. Add a method to HttpConnection which
retrieves all values with a given header field name with the field name
compared case insensitive.

Enable and fix warnings about redundant specification of type arguments
Since the introduction of generic type parameter inference in Java 7,
it's not necessary to explicitly specify the type of generic parameters.
Enable the warning in Eclipse, and fix all occurrences.

Enable and fix 'Should be tagged with @Override' warning
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.

Per the interface specification, the getContentLength method should
return -1 if content length is unknown or greater than
Integer.MAX_VALUE.
For chunked transfer encoding, the content length is not included in the
header, hence will cause a NullPointerException when trying to parse the
content length header.

HttpClientConnection uses a TemporaryBufferEntity which uses
TemporaryBuffer.LocalFile to buffer an HttpEntity. It was leaking
temporary files if the buffered entities were larger than 1MB since it

Add an implementation for HttpConnection using Apache HttpClient
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.
