DfsReftableDatabase is a new alternative for DfsRefDatabase that
handles more operations for the implementor by delegating through
reftables. All reftable files are stored in sibling DfsObjDatabase
using PackExt.REFTABLE and PackSource.INSERT.
Its assumed the DfsObjDatabase periodically runs compactions and GCs
using DfsPackCompactor and DfsGarbageCollector. Those passes are
essential to collapsing the stack of reftables.

Allow creating symbolic references with link, and deleting them or
switching to ObjectId with unlink. How this happens is up to the
individual RefDatabase.
The default implementation detaches RefUpdate if a symbolic reference
is involved, supporting these command instances on RefDirectory.
Unfortunately the packed-refs file does not support storing symrefs,
so atomic transactions involving more than one symref command are
failed early.
Updating InMemoryRepository is deferred until reftable lands, as I
plan to switch InMemoryRepository to use reftable for its internal
storage representation.

Shadow commits in the RevWalk in the UploadPack object may cause the
UNINTERESTING flag not being carried over to their parents commits since
they were marked NO_PARENTS during the assumeShallow or
initializeShallowCommits call.
A new RevWalk needs to be created for this reason, but instead of
creating a new RevWalk from Repository, we can reuse the ObjectReader in
the RevWalk of UploadPack to load objects.

Per git-config(1), core.logAllRefUpdates auto-creates reflogs for HEAD
and for refs under heads, notes, tags, and for HEAD. Add notes and
remove stash from ReflogWriter#shouldAutoCreateLog. Explicitly force
writing reflogs for refs/stash at call sites, now that this is
supported.

Even if a repository has core.logAllRefUpdates=true, ReflogWriter does
not create reflog files unless the refs are under a hard-coded list of
prefixes, or unless the forceWrite bit is set. Expose the forceWrite bit
on a per-update basis in RefUpdate/BatchRefUpdate/ReceiveCommand,
creating RefLogWriters as necessary.
Change-Id: Ifc851fba00f76bf56d4134f821d0576b37810f80
The ReflogWriter constructor just took a Repository and called
getDirectory() on it to figure out the reflog dirs, but not all
Repository instances use this storage format for reflogs, so it's
incorrect to attempt to use ReflogWriter when there is not a
RefDirectory directly involved. In practice, ReflogWriter was mostly
only used by the implementation of RefDirectory, so enforcing this is
mostly just shuffling around calls in the same internal package.
The one exception is StashDropCommand, which writes to a reflog lock
file directly. This was a reasonable implementation decision, because
there is no general reflog interface in JGit beyond using
(Batch)RefUpdate to write new entries to the reflog. So to implement
"git stash drop <N>", which removes an arbitrary element from the
reflog, it's fair to fall back to the RefDirectory implementation.
Creating and using a more general interface is well beyond the scope of
this change.
That said, the old behavior of writing out the reflog file even if
that's not the reflog format used by the given Repository is clearly
wrong. Fail fast in this case instead.

This test was never being run. Since it was introduced it was
named "notest.." which meant it didn't run with JUnit3, and
since it is not annotated @Test it also doesn't run with JUnit4.
When compiling with Bazel 0.6.0, error-prone raises an error
that the public method is not annotated with @Ignore or @Test.
Given that the test has never been run anyway, we can just

Same problem as in commit c227268: openUserConfig() just creates the
FileBasedConfig object, but doesn't read the file yet. An explicit
load() is needed.
As HttpConfig is read-only this omission did not cause any bad effects,
but it simply ignored values from the user config. Most uses of
HttpConfig go through the two-argument constructor, though, where
HttpConfig is given an already loaded repo config.

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.

With atomic ref updates using packed refs, JGit did not fire a
RefsChangedEvent. This resulted in a user-visible regression in
EGit: the UI would not update after a "Fetch from upstream...".
Presumably it would also make Gerrit miss out on ref changes?
Strengthen the BatchRefUpdateTest by also asserting the expected
number of RefsChangedEvents, and ensure modCnt is incremented in
RefDirectory.commitPackedRefs() when refs really changed (as opposed
to some internal housekeeping operation, such as packing loose refs).

An application can choose to invoke setAdvertisedRefs multiple times,
for example several AdvertiseRefsHook installed in a chain. Each of
these invocations populates the advertisedHaves collection with the
unique set of ObjectIds.
This can lead to a server over-advertising with ".have" lines if the
first hook pushes in a lot of references, and the second hook filters
this to a subset. ReceivePack will advertise the unique objects from
the first hook using ".have" lines, which may lead to a huge
advertisement sent to the client.
This can also contribute to a very slow connectivity check after the
pack is parsed as ReceivePack calls markUninteresting on every commit
in advertisedHaves. This may require expanding a lot of subtrees to
mark all trees as uninteresting as well. On a very big repository
this can lead to a many-second stall.
Clear the advertisedHaves collection any time the refs are updated.
Add a test to verify the correct set of objects was sent.

If a ReftableConfig has been supplied by the caller, write out a

To bootstrap from a non-reftable system, the refs are read from the
DfsRefDatabase if no GC reftables are present. Its assumed the
references are fully current, and do not need to be merged with any
other reftables. Any non-GC reftables will be pruned at the end of
the GC cycle, just like any packs that were replaced.
If a GC reftable is present, all existing reftables are compacted, and
references from DfsRefDatabase are only used to seed the packer. Its
assumed these are consistent with each other.
