On the first attempt to move the temp file, NoSuchFileException can
be raised if the destination folder does not exist. Instead of handling
this implicitly in the catch of IOException and then continuing to
create the destination folder and try again, explicitly catch it and
create the destination folder. If any other IOException occurs, treat
it as an unexpected error and return FAILURE.
Subsequently, on the second attempt to move the temp file, if ANY kind
of IOException occurs, also consider this an unexpected error and
return FAILURE.
In both catch blocks for IOException, add logging at ERROR level.

If atomic move is not supported, AtomicMoveNotSupportedException will
be thrown on the first attempt to move the temp file. There is no
point attempting the move operation a second time because it will only
fail for the same reason.
Add an immediate return of FAILURE on the first occasion. Remove the
unnecessary handling of the exception in the second block.

As discussed in the bug, jgit should not include a logging
implementation, and instead rely on the product containing jgit to
configure the logging.
We have recently run into the situation, that installing egit in a (non
eclipse.org) RCP application breaks all the logging due to incompatible
logging implementations. Removal of the jgit logging implementation
should fix this.
Following further changes have been done for jgit command line:
* added log4j.properties to binary build of jgit.pgm. That file existed
in the git repository, but was not included in the eclipse binary build.
(maybe it is in the bazel build)
* removed apache.commons.logging package import from jgit.pgm. That
import is not used, and makes the logging even more confusing.

Motivation: JSch serves as 'default' implementations of the SSH
transport. If a client application does not use it then there is no need
to pull in this dependency.
Move the classes depending on JSch to an OSGi fragment extending the
org.eclipse.jgit bundle and keep them in the same package as before
since moving them to another package would break API. Defer moving them
to a separate package to the next major release.
Add a new feature org.eclipse.jgit.ssh.jsch feature to enable
installation. With that users can now decide which of the ssh client
integrations (JCraft JSch or Apache Mina SSHD) they want to install.
We will remove the JCraft JSch integration in a later step due to the
reasons discussed in bug 520927.

Motivation: BouncyCastle serves as 'default' implementation of

to pull in this dependency, especially since BouncyCastle is a large
library.
Move the classes depending on BouncyCastle to an OSGi fragment extending

package in order to avoid split packages. This doesn't break public API
since these classes were already in an internal package before this
change.

that users can now decide if they want to install it.

If the determination of the user home directory produces a Java File
object with an invalid path, spurious exceptions may occur at the
most inopportune moments anytime later. In the case in the linked bug
report, start-up of EGit failed, leading to numerous user-visible
problems in Eclipse.
So validate the return value of FS.userHomeImpl(). If converting that
File to a Path throws an exception, log the problem and fall back to
Java system property user.home. If that also is not valid, use null.
(A null user home directory is allowed by FS, and calling in Java
new File(null, "some_string") is fine and produces a File relative
to the current working directory.)

Avoid trying other authentication methods on SocketException or on
InterruptedIOException. SocketException is rather fatal, such as
nothing listening on the peer's port, connection reset, or it could
be a connection time-out.
Time-outs enforced by Timeout{Input,Output}Stream may result in
InterruptedIOException being thrown.
In both cases, it makes no sense to try other authentication methods,
and doing so may wrongly report "authentication not supported" or
"cannot open git-upload-pack" or some such instead of reporting a
time-out.

In Git 2.10.0 the interpretation of gitattributes changed or was fixed
such that "* text=auto eol=crlf" would indeed still do auto-detection

"* text eol=crlf", i.e., treating all files as text.
JGit still did the latter, which caused surprises because it changed

Currently we're buffering the inflated bitmap entry in BasePackBitmapIndex
to optimize running time. However, this will use lots of memory during
the construction of the pack bitmap index file which may cause failure of
garbage collection.
The running time didn't increase significantly, if there's any increase,
after removing the buffering here. The report about usage of time/memory
will come in the next commit.

The convertedBitmaps serves for time-optimization purpose. But it's
actually not saving time much but using lots of memory. So remove the
field here to save memory.
Currently the remapper class is only used in the construction of the
bitmap index file. And during the preparation of the file, we're only
getting bitmaps from the remapper when finding objects accessible from
a commit, so bitmap associated with each commit will only be fetched once
and thus the convertedBitmaps would hardly be read, which means that it's
not saving time.

Currently, the garbage collection is consistently failing for some large
repositories in the building bitmap phase, e.g.Linux-MSM project:
https://source.codeaurora.org/quic/la/kernel/msm-3.18
Historically, bitmap index creation happened in 3 phases:
1. Select the commits to which bitmaps should be attached.
2. Create all bitmaps for these commits, stored in uncompressed format
in the PackBitmapIndexBuilder.
3. Deltify the bitmaps and write them to disk.
We investigated the process. For phase 2 it's most efficient to create
bitmaps starting with oldest commit and moving to the newest commit,
because the newer commits are able to reuse the work for the old ones.
But for bitmap deltification in phase 3, it's better when a newer
commit's bitmap is the base, and the current disk format writes bitmaps
out for the newest commits first.
This change introduces a new collection to hold the deltified and
compressed representations of the bitmaps, keeping a smaller subset of
commits in the PackBitmapIndexBuilder to help make the bitmap index
creation more memory efficient.
And in this commit, we're setting DISTANCE_THRESHOLD to 0 in the
PackWriterBitmapPreparer, which means the garbage collection will not
have much behavoir change and will still use as much memory as before.

a client-provided {@code BitmapBuilder} as a side effect of a revwalk.
Similar to {@code AddToBitmapFilter}, it short circuits the walk when it
encounters a commit which is included in the provided bitmap's BitmapIndex.
It also short circuits the walk if it encounters the client-provided
cached commit.

another branch)
- Additional list of references we know client can be interested in
(e.g. list of open changes for Gerrit)
We tested it inside Google and it improves connectivity for certain

percentile_90: 23272 (was: 353003)
