Pretty printing the response is useful for human readers, but most
(if not all) of the time, the response will be read by programs.
Remove it to avoid the additional overhead of the formatting and
extra bytes in the response. Adjust the test accordingly.
Note that LfsProtocolServlet already doesn't use pretty printing,
so this change makes FileLfsServlet's behavior consistent. In fact,
both classes now have duplicate Gson handling; this will be cleaned

When a GC operation is interrupted, temporary packs and indexes can be
left on the pack folder. In big, busy repositories this can lead to
significant amounts of wasted disk space if this interruption is done
with a certain frequency.
Remove stale temporary packs and indexes at the end of the GC process so
they do not accumulate. To avoid interfering with a possible concurrent
JGit GC process in the same repository, only delete temporary files that
are older than one day.

When running on NFS there was a chance that JGits LockFile
semantic is broken because File#createNewFile() may allow
multiple clients to create the same file in parallel. This
change provides a fix which is only used when the new config
option core.supportsAtomicCreateNewFile is set to false. The
default for this option is true. This option can only be set in the
global or the system config file. The repository config file is not
taken into account in this case.
If the config option core.supportsAtomicCreateNewFile is true
then File#createNewFile() is trusted and the behaviour doesn't
change.
But if core.supportsAtomicCreateNewFile is set to false then after
successful creation of the lock file a hardlink to that lock file is
created and the attribute nlink of the lock file is checked to be 2. If
multiple clients manage to create the same lock file nlink would be
greater than 2 showing the error.
This expensive workaround is described in
https://www.time-travellers.org/shane/papers/NFS_considered_harmful.html

Then list of packed refs was cached in RefDirectory based on mtime of
the packed-refs file. This may fail on NFS when attributes are cached.
A cached mtime of the packed-refs file could cause JGit to trust the
cached content of this file and to overlook that the file is modified.
Honor the config option trustFolderStats and always read the packed-refs
content if the option is false. By default this option is set to true
and this fix is not active.

Jsch 0.1.54 passes on the values from ~/.ssh/config for
"ServerAliveInterval" and "ConnectTimeout" as read from
the config file to java.net.Socket.setSoTimeout(). That
method expects milliseconds, but the values in the config
file are seconds!
The missing conversion in Jsch means that the timeout is
set way too low, and if the server doesn't respond within
that very short time frame, Jsch kills the connection and
then throws an exception with a message such as "session is
down" or "timeout in waiting for rekeying process".
As a work-around, do the conversion to milliseconds in the
Jsch-facing Config interface of OpenSshConfig. That way Jsch
already gets these values as milliseconds.

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.

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

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.
