Robin Rosenberg b3e59bd9d6 Implement a revert command
This is almost reverted cherry-pick, and the implementation is
almost identical. It orders the input to merge differently to get
the effect and produces a different commit message with the
default author, rather than the original author.

Robin Rosenberg d9e07a574a Convert all JGit unit tests to JUnit 4
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

Robin Rosenberg 797ebba307 Add support for getting the system wide configuration
These settings are stored in <prefix>/etc/gitconfig. The C Git
binary is installed in <prefix>/bin, so we look for the C Git
executable to find this location, first by looking at the PATH
environment variable and then by attemting to launch bash as
a login shell to find out.

Shawn Pearce 4da775eaff Merge "IndexPack: Use stack-based recursion for delta resolution" 2010-12-30 19:52:47 -05:00
roberto b5f0a7d7ff IndexPack: Use stack-based recursion for delta resolution
Replace 'method' with 'heap'-based recursion for resolving deltas.

Git packfile delta-chain depth can exceed 50 levels in certain files
(the packfile of the JGit project itself has >800 objects with
chain-length >50). Using method-based recursion on such packfiles will
quickly throw a StackOverflowError on VMs with constrained stack.

Benefits:

* packfile delta-resolution no longer limited by the maximum number
  of stack frames permitted on the current thread.

* slight performance improvement
  (3% speed increase on the packfile of the JGit project)

Robin Rosenberg c3f52c62a8 Fix FileSnapShot
We cannot use SystemReader to get the time, unless we do that consistently,
which is harder to do and be sure we are really testing what we want.

Then we need to update our lastRead variable whenever we conclude that
our file is not racily clean according to lastRead. It may well be clean,
but we do not know that until we check the system clock again.

Finally add a test for this class.

Shawn O. Pearce 6533994bc9 Fix ArrayIndexOutOfBoundsException in DirCacheIterator
If the 'TREE' extension contains an invalid subtree that has
been removed, DirCacheIterator still tried to access it due to
an invalid childCnt field within the parent DirCacheTree object.
This is easy for a user to do, they just need to move all files
out of a subdirectory.

For example, the input for the JUnit test case for this bug was
built using the following C Git sequence:

  mkdir -p a/b
  touch a/b/c q
  git add a/b/c q
  git write-tree
  git mv a/b/c a/a

After the last step, the subdirectory a/b is empty, as its only
file was moved into the parent directory.  Because of the earlier
`git write-tree` operation, there is a 'TREE' extension present, but
the a and a/b subdirectories have been marked invalid by the rename.

When JGit tried to iterate over the a tree, it tried to correct
childCnt to be zero as a/b no longer exists, but it failed to
update childCnt.

Shawn O. Pearce 013cb8de38 Reduce calls to Repository.getConfig
Each time getConfig() is called on FileRepository, it checks the
last modified time of both ~/.gitconfig and $GIT_DIR?config.  If
$GIT_DIR/config appears to have been modified, it is read back in
from disk and the current config is wiped out.

When mutating a configuration file, this may cause in-memory edits
to disappear.  To avoid that callers need to avoid calling getConfig
until after the configuration has been saved to disk.

Unfortunately the API is still horribly broken.  Configuration should
be modified only while a lock is held on the configuration file, very
similar to the way a ref is updated via its locking protocol.  But our
existing API is really broken for that so we'll have to defer cleaning
up the edit path for a future change.

roberto 941b3d8a81 IndexPack: Remove blob-streaming size threshold
Always use streaming (for SHA-checksum & collision detection)
when indexing whole blobs, regardless of their size.

Positives:
* benefits of bugfix #312868 will apply to all runtimes, without
  additional conf for mem-constrained JVMs (5MB huge for some)
* no byte array allocation
  (re-uses readBuffer instead of allocating new full-size array)
* mildly better overall performance
  (given the usual blob-does-not-need-collision-checking case)
* removes unnecessary code

Negative:
* doubles the disk IO for a blob comparision
  (comparitively rare occurance)

I perf-tested a range of threshold sizes against a random selection
of packfiles I found on my harddrive, the results are here:

https://spreadsheets.google.com/ccc?key=tLCQElyyd2RKN9QevfvgwGQ&hl=en_GB#gid=1

My interpretation of the results is that the streaming size threshold
isn't beneficial (actually seems to be very slightly detrimental) -so
we should just get rid of it. This tallies with some of the comments
Shawn & I had for the default value of streamFileThreshold in the
review for I862afd4c:

http://egit.eclipse.org/r/#patch,sidebyside,2040,2,org.eclipse.jgit/src/org/eclipse/jgit/transport/IndexPack.java

The perf-test code is here: https://gist.github.com/735402
It's a bit scruffy but basically does 10 runs (in randomised order)
for each threshold size on various packfiles, waiting a second
between each pack-indexing to allow GC to catch up. I know it's not
perfect - proper perf testing is hard to do :-)
