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.

UploadPack: Test filtering by AdvertiseRefsHook in stateless transports
AdvertiseRefsHook is used to limit the visibility of the refs in Gerrit.
If this hook is not called, then all refs are treated as visible,
causing the server to serve commits reachable from branches the client
should not be able to access, if asked to via a request naming a guessed
object id.
Until 3a529361a7 (Call AdvertiseRefsHook
before validating wants, 2018-12-18), UploadPack would invoke this hook
at ref advertisement time but not during negotiation and when serving a
pack file. Add a test to avoid regressing. Stateful bidirectional
transports were not affected, so the test uses HTTP.
[jn: split out when backporting the fix to stable-4.5. The test passes
as long as v4.9.0.201710071750-r~169 (fetch: Accept any SHA-1 on lhs of
refspec, 2017-06-04) is cherry picked along with it.]

HttpClientConnectionTest: Throw UnsupportedOperationException for unused methods
The HttpResponseMock class is only used in a single test to assert
on the expected headers. All of its overridden methods are empty, and
this results in warnings in Eclipse:
'Empty block should be documented'
Rather than adding "// Not used" comments, change all of the methods'
implementations to throw UnsupportedOperationException. This not only
gets rid of the warnings, but also makes it explicit that we don't
intend any of them to actually be called.

When a https connection could not be established because the SSL
handshake was unsuccessful, TransportHttp would unconditionally
throw a TransportException.
Other https clients like web browsers or also some SVN clients
handle this more gracefully. If there's a problem with the server
certificate, they inform the user and give him a possibility to
connect to the server all the same.
In git, this would correspond to dynamically setting http.sslVerify
to false for the server.
Implement this using the CredentialsProvider to inform and ask the
user. We offer three choices:
1. skip SSL verification for the current git operation, or
2. skip SSL verification for the server always from now on for
requests originating from the current repository, or
3. always skip SSL verification for the server from now on.
For (1), we just suppress SSL verification for the current instance of
TransportHttp.
For (2), we store a http.<uri>.sslVerify = false setting for the
original URI in the repo config.
For (3), we store the http.<uri>.sslVerify setting in the git user
config.
Adapt the SmartClientSmartServerSslTest such that it uses this
mechanism instead of setting http.sslVerify up front.
Improve SimpleHttpServer to enable setting it up also with HTTPS
support in anticipation of an EGit SWTbot UI test verifying that
cloning via HTTPS from a server that has a certificate that doesn't
validate pops up the correct dialog, and that cloning subsequently
proceeds successfully if the user decides to skip SSL verification.

Git has a rather elaborate mechanism to specify HTTP configuration
options per URL, based on pattern matching the URL against "http"
subsection names.[1] The URLs used for this matching are always the
original URLs; redirected URLs do not participate.
* Scheme and host must match exactly case-insensitively.
* An optional user name must match exactly.
* Ports must match exactly after default ports have been filled in.
* The path of a subsection, if any, must match a segment prefix of
the path of the URL.
* Matches with user name take precedence over equal-length path
matches without, but longer path matches are preferred over
shorter matches with user name.
Implement this for JGit. Factor out the HttpConfig from TransportHttp
and implement the matching and override mechanism.
The set of supported settings is still the same; JGit currently
supports only followRedirects, postBuffer, and sslVerify, plus the
JGit-specific maxRedirects key.
Add tests for path normalization and prefix matching only on segment
separators, and use the new mechanism in SmartClientSmartServerSslTest
to disable sslVerify selectively for only the test server URLs.
Compare also bug 374703 and bug 465492. With this commit it would be
possible to set sslVerify to false for only the git server using a
self-signed certificate instead of having to switch it off globally
via http.sslVerify.

Cleanup: message reporting for HTTP redirect handling
The addition of "tooManyRedirects" in commit 7ac1bfc ("Do
authentication re-tries on HTTP POST") was an error I didn't
catch after rebasing that change. That message had been renamed
in the earlier commit e17bfc9 ("Add support to follow HTTP
redirects") to "redirectLimitExceeded".
Also make sure we always use the TransportException(URIish, ...)
constructor; it'll prefix the message given with the sanitized URI.
Change messages to remove the explicit mention of that URI inside the
message. Adapt tests that check the expected exception message text.
For the info logging of redirects, remove a potentially present
password component in the URI to avoid leaking it into the log.

There is at least one git server out there (GOGS) that does
not require authentication on the initial GET for
info/refs?service=git-receive-pack but that _does_ require
authentication for the subsequent POST to actually do the push.
This occurs on GOGS with public repositories; for private
repositories it wants authentication up front.
Handle this behavior by adding 401 handling to our POST request.
Note that this is suboptimal; we'll re-send the push data at
least twice if an authentication failure on POST occurs. It
would be much better if the server required authentication
up-front in the GET request.
Added authentication unit tests (using BASIC auth) to the
SmartClientSmartServerTest:
- clone with authentication
- clone with authentication but lacking CredentialsProvider
- clone with authentication and wrong password
- clone with authentication after redirect
- clone with authentication only on POST, but not on GET
Also tested manually in the wild using repositories at try.gogs.io.
That server offers only BASIC auth, so the other paths
(DIGEST, NEGOTIATE, fall back from DIGEST to BASIC) are untested
and I have no way to test them.
* public repository: GET unauthenticated, POST authenticated
Also tested after clearing the credentials and then entering a
wrong password: correctly asks three times during the HTTP
POST for user name and password, then gives up.
* private repository: authentication already on GET; then gets
applied correctly initially to the POST request, which succeeds.
Also fix the authentication to use the credentials for the redirected
URI if redirects had occurred. We must not present the credentials
for the original URI in that case. Consider a malicious redirect A->B:
this would allow server B to harvest the user credentials for server
A. The unit test for authentication after a redirect also tests for
this.

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.
