Reorder modifiers to follow Java Language Specification
The Java Language Specification recommends listing modifiers in
the following order:
1. Annotations
2. public
3. protected
4. private
5. abstract
6. static
7. final
8. transient
9. volatile
10. synchronized
11. native
12. strictfp
Not following this convention has no technical impact, but will reduce
the code's readability because most developers are used to the standard
order.
This was detected using SonarLint.

Remove it from
* package private functions.
* try blocks
* for loops
this was done with the following python script:
$ cat f.py
import sys
import re
import os
def replaceFinal(m):
return m.group(1) + "(" + m.group(2).replace('final ', '') + ")"
methodDecl = re.compile(r"^([\t ]*[a-zA-Z_ ]+)\(([^)]*)\)")
def subst(fn):
input = open(fn)
os.rename(fn, fn + "~")
dest = open(fn, 'w')
for l in input:
l = methodDecl.sub(replaceFinal, l)
dest.write(l)
dest.close()
for root, dirs, files in os.walk(".", topdown=False):
for f in files:
if not f.endswith('.java'):
continue
full = os.path.join(root, f)
print full
subst(full)

Significantly speed up FileTreeIterator on Windows
Getting attributes of files on Windows is an expensive operation.
Windows stores file attributes in the directory, so they are
basically available "for free" when a directory is listed. The
implementation of Java's Files.walkFileTree() takes advantage of
that (at least in the OpenJDK implementation for Windows) and
provides the attributes from the directory to a FileVisitor.
Using Files.walkFileTree() with a maximum depth of 1 is thus a
good approach on Windows to get both the file names and the
attributes in one go.
In my tests, this gives a significant speed-up of FileTreeIterator
over the "normal" way: using File.listFiles() and then reading the
attributes of each file individually. The speed-up is hard to
quantify exactly, but in my tests I've observed consistently 30-40%
for staging 500 files one after another, each individually, and up
to 50% for individual TreeWalks with a FileTreeIterator.
On Unix, this technique is detrimental. Unix stores file attributes
differently, and getting attributes of individual files is not costly.
On Unix, the old way of doing a listFiles() and getting individual
attributes (both native operations) is about three times faster than
using walkFileTree, which is implemented in Java.
Therefore, move the operation to FS/FS_Win32 and call it from
FileTreeIterator, so that we can have different implementations
depending on the file system.
A little performance test program is included as a JUnit test (to be
run manually).
While this does speed up things on Windows, it doesn't solve the basic
problem of bug 532300: the iterator always gets the full directory
listing and the attributes of all files, and the more files there are
the longer that takes.

Use constants from StandardCharsets instead of hard-coded strings
Instead of hard-coding the charset strings "US-ASCII", "UTF-8", and
"ISO-8859-1", use the corresponding constants from StandardCharsets.
UnsupportedEncodingException is not thrown when the StandardCharset
constants are used, so remove the now redundant handling.
Because the encoding names are no longer hard-coded strings, also
remove redundant $NON-NLS warning suppressions.
Also replace existing usages of the constants with static imports.

When invoking File.toPath(), an (unchecked) InvalidPathException may be
thrown which should be converted to a checked IOException.
For now, we will replace File.toPath() by FileUtils.toPath() only for
code which can already handle IOExceptions.

it's not necessary to explicitly specify the type of generic parameters.

Deprecate TemporaryBuffer.LocalFile without parent directory
Encourage callers to explicitly name a directory to hold any
overflow data. Call sites have more information about what is
going into the buffer and how it should be protected at the
filesystem level than just throwing content to the system wide
temporary directory.
Callers that still really don't care (or need to care) can pass
null for the File argument to have the system directory used.

A few places were still using GitIndex. Replacing it was fairly
simple, but there is a difference in test outcome in
ReadTreeTest.testUntrackedConflicts. I believe the new behavior
is good, since we do not update neither the index, not the worktree.

The mapTree() routines have been deprecated for a long time, and their
sibilings for mapCommit() and mapTag() were already removed from the
main Repository API.
Remove mapTree(). Application callers who only need the tree's name
can use resolve("^{tree}") syntax to resolve to the tree ObjectId, or
fail if the input is not a tree.
Applications that want to read a tree should use DirCache or TreeWalk.

Eclipse has some problem re-running single JUnit tests if
the tests are in Junit 3 format, but the JUnit 4 launcher
is used. This was quite unnecessary and the move was not
completed. We still have no JUnit4 test.
This completes the extermination of JUnit3. Most of the
work was global searce/replace using regular expression,
followed by numerous invocarions of quick-fix and organize
imports and verification that we had the same number of
tests before and after.
- Annotations were introduced.
- All references to JUnit3 classes removed
- Half-good replacement for getting the test name. This was
needed to make the TestRngs work. The initialization of
TestRngs was also made lazily since we can not longer find
out the test name in runtime in the @Before methods.
- Renamed test classes to end with Test, with the exception
of TestTranslateBundle, which fails from Maven
- Moved JGitTestUtil to the junit support bundle

This better matches with the name used in the environment
(GIT_WORK_TREE), in the configuration file (core.worktree),
and in our builder object.
Since we are already breaking a good chunk of other code
related to repository access, and this fairly easy to fix
in an application's code base, I'm not going to offer the
wrapper getWorkDir() method.

The mapCommit API is being deprecated because it doesn't run very
fast. Leaving tests around to test how fast it is relative to C Git
isn't instructive. Remove them, which should help aid the transition
away from the mapCommit API.

On Windows, FS_Win32_Cygwin has been used if a Cygwin Git installation
is present in the PATH. Assuming that the user works with the Cygwin
Git installation may result in unnecessary overhead if he actually
does not.
Applications built on top of jgit may have more knowledge on the
actually used Git client (Cygwin or not) and hence should be able to
configure which FS to use accordingly.

Refactor TemporaryBuffer to support reuse in other contexts
Later we are going to add support for smart HTTP, which requires us to
buffer at least some of the request created by a client before we ship
it to the server. For many requests, we can fit it completely into a
1 MiB buffer, but if it doesn't we can drop back to using the chunked
transfer encoding to send an unknown stream length.
Rather than recoding the block based memory buffer, we refactor the
local file overflow strategy into a subclass, allowing the HTTP client
code to replace this portion of the logic with its own approach to
start the chunked encoding request.
