DfsFsck: Skip unborn branches and symrefs to nowhere
The map returned by getAllRefs includes all refs, including symrefs like
HEAD that may not point to any object yet. That is a valid state (e.g.,
in a new repository that has just been created by "git init"), so skip
such refs.
Thomas Wolf [Thu, 14 Dec 2017 12:24:00 +0000 (13:24 +0100)]
Write packed-refs directly when cloning
When we are cloning we have no refs at all yet, and there cannot
(or at least should not) be any other thread doing something with
refs yet.
Locking loose refs is thus not needed, since there are no loose
refs yet and nothing should be trying to create them concurrently.
Let's skip the whole loose ref locking when we are cloning a repository.
As a result, JGit will write the refs directly to the packed-refs
file, and will not create the refs/remotes/ directories nor the
lock files underneath when cloning and packed refs are used. Since
no lock files are created, any problems on case-insensitive file
systems with tag or branch names that differ only in case are avoided
during cloning.
Detect if we are cloning based on the following heuristics:
* HEAD is a dangling symref
* There is no loose ref
* There is no packed-refs file
Note, however, that there may still be problems with such tag or
branch names later on. This is primarily a five-minutes-past-twelve
stop-gap measure to resolve the referenced bug, which affects the
Oxygen.2 release.

Config: Remove the include functionality
The Config class must be safe to run against untrusted input files.
Reading arbitrary local system paths using include.path is risky for
servers, including Gerrit Code Review.
This was fixed on master [1] by making "readIncludedConfig" a noop
by default. This allows only FileBasedConfig, which originated from
local disk, to read local system paths.
However, the "readIncludedConfig" method was only introduced in [2]
which was needed by [3], both of which are only on the master branch.
On the stable branch only Config supports includes. Therefore this
commit simply disables the include functionality.

Fix IllegalThreadStateException if stderr closed without exiting
If some process executed by FS#readPipe lived for a while after

Add Process#waitFor calls to wait for the process completion.
CloneCommand: Refactor listing of files in deleteChildren
File.listFiles() returns null if the given File does not represent a
directory, so we can just test for null instead of making a separate
call to FS.DETECTED.isDirectory()
This also avoids a false-positive error from SpotBugs which claims
that there is a potential null-pointer exception on dereferencing the
result of Files.listFiles().

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
up in a separate change.

RepoCommand: Skip RemoteReader when encountering a full SHA-1
There is no point in calling back to the RemoteReader to resolve a
40-digit hex SHA-1 to itself. We already skip that call when not
ignoring remote failures; skip it when ignoring remote failures, too.
This should simplify RemoteReader implementations.
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.

Performance improvement on writing a large index
The index header consists of a 4-byte version number. The current
supported version numbers are 2 and 3. The code checks if any entries
are extended. If it finds any entries that are extended it picks version
'3', otherwise it chooses version '2'.
DirCache.java
-Changed the 'extended' check to exit early when any entry is considered
'extended' in the index.
(Of course, I maybe missing a bitwise optimization that is made in
the Java bytecode.)
