JSch unconditionally overrides the user name given in the connection
URI by the one found in ~/.ssh/config (if that does specify one for
the used host). If the SSH config file has a different user name,
we'll end up using the wrong name, which typically results in an
authentication failure or in Eclipse/EGit asking for a password for
the wrong user.
Unfortunately there is no way to prevent or circumvent this Jsch
behavior up front; it occurs already in the Session constructor at
com.jcraft.jsch.Session() and the Session.applyConfig() method. And
while there is a Session.setUserName() that would enable us to correct
this, that latter method has package visibility only.
So resort to reflection to invoke that setUserName() method to ensure
that Jsch uses the user name from the URI, if there is one.

Applications that use ObjectInserters to create lots of individual
objects may prefer to avoid cluttering up the object directory with
loose objects. Add a specialized inserter implementation that produces a
single pack file no matter how many objects. This inserter is loosely
based on the existing DfsInserter implementation, but is simpler since
we don't need to buffer blocks in memory before writing to storage.
An alternative for such applications would be to write out the loose
objects and then repack just those objects later. This operation is not
currently supported with the GC class, which always repacks existing
packs when compacting loose objects. This in turn requires more
CPU-intensive reachability checks and extra I/O to copy objects from old
packs to new packs.
So, the choice was between implementing a new variant of repack, or not
writing loose objects in the first place. The latter approach is likely
less code overall, and avoids unnecessary I/O at runtime.
The current implementation does not yet support newReader() for reading
back objects.

GC explicitly handles the case where a new pack has the same name as an
existing pack due to it containing the exact same set of objects. In
this case, the pack passed to insertPack will have the same name as an
existing pack, but it will also almost certainly have a later mtime than
the existing pack.
The loop in insertPack tried to short-circuit when inserting a new pack,
to avoid walking more of the pack list than necessary. Unfortunately,
this means it will never get to the check for an identical name,
resulting in a duplicate entry for the same PackFile in the pack list.
Remove the short-circuit so that insertPack does not insert a duplicate
entry.

So far we follow OSGi semantic versioning [1] which says the following:
"A change in the second (minor) part of the version signals that the
change is backward compatible with consumers of the API package but not
with the providers of that API. That is, when the API package goes from
version 1.5 to 1.6 it is no longer compatible with a provider of that
API but consumers of that API are backward compatible with that API
package."
The change Ib5fbf17bdaf727bc5d0e106ce88f2620d9f87a6f broke EMF Compare
which subclasses ResolveMerger since we added a new parameter to the
protected ResolveMerger.processEntry() method. According to the above
cited OSGi semantic versioning this is ok, implementers should expect
that they break on minor version changes of the API they implement.
This change reintroduces the old processEntry() method in order to help
avoid breakage for existing EMF Compare versions which expect breakage
also for the implementer case only for major version change (in this
case from JGit 4.x to 5.x).

Do tilde replacement for values from the ssh config file that are
file names in all cases to make sure that they are already replaced
when Jsch tries to get the values.
Previously, OpenSshConfig did tilde replacement only for the
IdentityFile in the JGit-facing "Host" interface and left the
replacement in the Jsch-facing "Config" interface to Jsch.
But on Windows the JGit notion of what should be used to replace the
tilde differs from Jsch's replacement. Jsch always replaces the tilde
by the value of the system property "user.home", whereas JGit also
considers some environment variables like %HOME%. This can lead to
rather surprising failures as in the case of bug 526175 where
%HOME% != user.home.
Prior to commit 9d24470 (i.e.,prior to JGit 4.9.0) this problem never
occurred because Jsch was completely unaware of the ssh config file
and all host and IdentityFile handling happened exclusively in JGit.

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.

Same problem as in commit c227268: openUserConfig() just creates the
FileBasedConfig object, but doesn't read the file yet. An explicit

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.

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.
