Jevgeni Zelenkov 803debd7be Ensure a directory exists before trying to create/merge a file into it.
Since git doesn't keep track of empty directories, they should be
created first. Test case included demonstrates that using
StashApplyCommand(). Bugfix is applied to the DirCacheCheckout class,
because StashApplyCommand() uses it internally to apply a stash.

Robin Rosenberg d08b35532a Merge "Fix PlotCommit for commits with duplicate parents" 2012-08-05 06:51:27 -04:00
Robin Rosenberg b2f911bb69 Fix PlotCommit for commits with duplicate parents
JGit allows to create commits which have duplicate parents: e.g. a
commit X has first parent Y and second parent Y. Such commits are not
handled correctly by PlotCommit leading to wrong display of the history
in EGit. In such cases there is a never ending passing line drawn beside
all commits younger than the commit with duplicate parents. This commit
fixes this by explicitly checking for duplicate parents.

In a different commit we should fix JGit not to create commits with
duplicate parents. I think native git also doesn't allow such commits,
although history display in native git (gitk, git log --graph) is not
damaged by such commits.

Christian Halstrick 4c3f017a77 Garbage collector for FileRepositories
Implements a garbage collector for FileRepositories. Main ideas are
copied from the garbage collector for DFS based repos
(DfsGarbageCollector). Added functionalities are
- pruning loose objects
- handling of the index
- packing refs
- handling of reflogs (objects referenced from reflog will not be
pruned/)

These are features of a GC which are not handled in this change and
which should come with subsequent changes:
- unpacking packed objects into loose objects (to support that pruning
packed objects doesn't delete them until they are older than two weeks)
- expiration of reflogs
- support for configuration parameters (e.g. gc.pruneExpire)

Christian Halstrick 778fdfaec1 Again teach ResolveMerger to create more correct DirCacheEntry's
Currently, after a merge/cherry-pick/rebase, all index entries are
smudged as the ResolveMerger never sets entry lengths and/or
modification times. This change teaches it to re-set them at least for
things it did not touch. The other entries are then repaired when the
index is persisted, or entries are checked out.

The first attempt to get this in was commit
3ea694c252 which has been reverted.
Since then some fixes to ResolveMerger and a few more tests have
been added which check situations where the index is not matching
HEAD before we merge.

Christian Halstrick c9e507c0b9 Improve performance of persisting an index by magnitudes
When updating smudged entries use a pathfilter to iterate only over
working tree files which have an associated smudged index entry.

Commit dac66672df introduced that we
check and update smudged entries while persisting a dircache. Before
that commit adding a file to git caused  file i/o for the index file,
the object database (to store new content) and all files we wanted to
add (to read new content). After that commit we have additionally file
i/o for every file in the working tree (even ignored files).
Especially on windows iterating over the working tree can be very
time consuming. This decreased the performance of persisting a dircache
dramatically (I measured factors 4 to 10 while adding a file to linux
kernel repo). One could easily see this effect when dragging&dropping
modified files in a linux kernel repo in the egit staging view.

Shawn O. Pearce 1c6c73c5a9 Work around smart HTTP bugs in C Git
I have unfortunately introduced a few bugs in the native Git client
over the years. 1.7.5 is unable to send chunked requests correctly,
resulting in corrupt data at the server. Ban this client whenever
it uses chunked encoding with an error message.

Prior to some more recent versions, git push over HTTP failed to
report status information and error messages due to a race within
the client and its helper process. Check for these bad versions and
send errors as messages before the status report, enabling users
to see the failures on their terminal.

Dave Borowitz dc23a7cc42 Make InMemoryRepository pack names globally unique
It was easy to create multiple packs with exactly the same name and
same DfsRepositoryDescription in a test, which can poison the
DfsBlockCache. The javadoc for DfsObjDatabase.newPack() explicitly
says pack names should be unique within an entire DFS, so do this by
making the packId AtomicInteger static.

Arguably, test writers shouldn't be doing things like putting
'new DfsRepositoryDescription("test")' in a setUp() method, but that's
a natural thing to do, and we don't document this restriction
anywhere.

Robin Stocker 14ff22fd74 Ignore empty lines when parsing git-rebase-todo
When starting a rebase with C Git, there may be empty lines in the
git-rebase-todo file. Before this change, JGit would fail to parse the
file with e.g. the following exception:

  JGitInternalException: Unknown or unsupported command "
  #", only "pick" is allowed.

This happened when there was an empty line just before the comments,
because the nextSpace would be the one from the comment. Now the empty
lines are ignored by checking for nextSpace < ptr outside of the loop.

Robin Stocker e623db0f87 Fix order of deletion for files/dirs in ResolveMerger
Before, the paths to delete were stored in a HashMap, which doesn't have
a particular order. So when e.g. both the file "a/b" and the directory
"a" were to be deleted, it would sometimes try to delete "a" first. This
resulted in a failed path because File#delete() fails when a directory
isn't empty.

With this change, an ArrayList is used for storing the paths to delete.
The list contains the paths in a top-down order, as defined by the order
of processEntry. When the files are deleted, the list is iterated in
reverse, ensuring that all files of a directory are deleted before the
directory itself.

Robin Stocker 028434e4f5 Don't return success on failing paths in ResolveMerger
ResolveMerger#mergeImpl() was only returning false (= failed) when there
were unmerged paths. In the case when there were only failing paths, it
returned true.

Because MergeCommand looks at the return value for determining if the
merge failed, it would fall into the successful case there, where it
should instead return a MergeResult with MergeStatus.FAILED.

This change adds a test case for this and makes the ResolveMerger return
false when there are failing paths.

This was discovered while working on fixing bug 354099 and is needed for
its test case.

Christian Halstrick 80113c7bb6 Fix resource leaks due to unclosed repositories
Whenever a call to JGit returns a Repository the caller should make sure
to call close() on it if he doesn't need it anymore. Since instances of
Repository contain e.g. open FileOutputStreams (for pack files)
forgetting to close the repository can lead to resource leaks.

This was the reason why dozens of the JUnit tests failed on Windows
with "Can't delete file ...." errors. 

In LocalDiskRepositoryTestCase.tearDown() we tried to delete the
repositories we used during tests which failed because we had open
FileOutputStreams.

Not only the obvious cases during Clone or Init operations returned
Repositories, but also the new SubModule API created repository
instances. In some places we even forgot to close submodule repositories
in our internal coding.

To see the effects of this fix run the JGit JUnit tests under Windows.
On other platforms it's harder to see because either the leaking
resources don't lead to failing JUnit tests (on Unix you can delete
files with open FileOutputStreams) or the java gc runs differently and
cleans up the resources earlier.
