Robin Stocker 51c20b27ac DirCacheCheckout: Fix handling of files not in index
When a file is not in the index and neither contents nor mode differ
between "head" and "merge", the index state should be kept. If they
differ, a checkout conflict should occur. This is described in Git's
git-read-tree.txt.

JGit used to replace the index state with "merge" in both of the above
cases.

A confusing effect of this was that when one removed a file and then did
a rebase, the file silently reappeared again.

The changes to dir/file conflict handling are a consequence of this
change, as the index handling change made tests in DirCacheCheckoutTest
break. I compared these cases to C Git and the new behavior there also
matches what C Git does.

Robin Rosenberg 0a9e010e14 Create an input stream that transforms LF to CRLF
The transformation is the same as AutoCRLFOutputStream does, but
the direction is reversed. The tests are reused, but the implementation
derives somewhat from the EolCanonicalizingInputStream.

This stream will be used to compare blobs with LF line endings with
worktree data that has CRLF line endings.

Christian Halstrick abd60101b6 Implement a parser for dates
In order to parse user specified strings containing date and time info
a thread-safe parser is implemented. This is needed for example to
interpret configuration parameters (e.g. gc.pruneexpire where need to
parse strings like "2 weeks ago"). The parser is thread-safe by caching
SimpleDateFormat instances in a ThreadLocal cache.

Native git has a parser called approxidate which is able to interpret a
huge number of formats ("1 year ago", "tea time", ...). Ideally JGit
should be able to parse the same strings as native git but for now this
parser understands the following subset:

"now"
"yesterday"
"(x) years|months|weeks|days|hours|minutes|seconds ago"
"yyyy-MM-dd HH:mm:ss Z" (ISO)
"EEE, dd MMM yyyy HH:mm:ss Z" (RFC)
"yyyy-MM-dd"
"yyyy.MM.dd"
"MM/dd/yyyy"
"dd.MM.yyyy"
"EEE MMM dd HH:mm:ss yyyy Z" (DEFAULT)
"EEE MMM dd HH:mm:ss yyyy" (LOCAL)

Christian Halstrick 252727c4fc Support branches with name 'config'
JGit was not able to lookup refs which had the name of files which exist
in the .git folder. When JGit was looking up a ref named X it has a
fixed set of directories where it searched for files named X
(ignore packed refs for now). First directory to search for is .git. In
case of the ref named 'config' it searched there for this file, found it
(it's the .git/config file with the repo configuration in it), parsed
it, found it is an invalid ref and stopped searching. It never looked
for a file .git/refs/heads/config.

I changed JGit in a way that when it finds a file in GIT_DIR which
corresponds to a ref name and if this file doesn't contain a valid ref
then it will ignore the InvalidObjectIdException and continue searching.

Robin Stocker 5854ca091a Improve ours/theirs conflict markers for rebase, cherry-pick
On conflicts in rebase or cherry-pick, the conflict markers were like
this:

    <<<<<<< OURS
    a
    =======
    b
    >>>>>>> THEIRS

This is technically correct, but it could be better.

It's especially confusing during a rebase, where the meaning of
OURS/THEIRS is not obvious. The intuition is that "ours" is the commits
that "I" did before the rebase, but it's the other way around because of
the way rebase works. See various bug reports and stackoverflow
discussions.

With this change, in the case of a cherry-pick while on master, the
markers will be like this:

    <<<<<<< master
    a
    =======
    b
    >>>>>>> bad1dea Message of the commit I'm cherry-picking

In the case of a "git rebase master":

    <<<<<<< Upstream, based on master
    a
    =======
    b
    >>>>>>> b161dea Message of a commit I'm rebasing

It's not "master" because that would only be correct for the first
cherry-pick during a rebase, after that, it's master + already
cherry-picked commits.

And in the case of a "git pull --rebase":

    <<<<<<< Upstream, based on branch 'master' of git@example.org:repo
    a
    =======
    b
    >>>>>>> b161dea Message of a commit I'm rebasing

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.

Robin Rosenberg 2a2362fbb3 Support parsing previous checkout as a revision expresion.
Repository.resolve can only return an ObjectId and will
continue to do so, but another method, simplify(), will
be able to return a branch name for some cases.

Previous checkouts can be specified as @{-n}, where n is an
integer speifying the n:th previous branch. The result
is the branch name, unless the checkout was a detached head,
in which case the object id is returned. Since the result
is a branch it may be followed by a references to the reflog,
such as @{-1}@{1} if necessary.

A simple expression like "master" is resolved to master in
simplify, but anything starting with refs gets resolved to
its object id, even if it is a branch.

A symbolic ref is resolved to its leaf ref, e.g. "HEAD" might
be resolved to "master".

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.

It is not always appropriate to use the .gitmodules file from the

And sometimes it is impossible, as in a bare repository.

When using the static factory methods, automatically set up the

the appropriate place. Leave the current behavior of looking in the

PackWriter supports excluding objects from being written to the pack.
You may specify a PackIndex which lists all those objects which should
not go into the new pack. This feature was broken because not all
commits have been checked whether they should be excluded or not. For
other object types the exclude algorithm worked. This commit adds the
missing check.

Robin Rosenberg 4e1454ded6 Git API does not declare GitAPIException call() and related cleanups
All commands should throw a GitAPIException so new exceptions can be
added without breaking the builds of old code, i.e. anyone that calls
a Git API should catch GitAPIException and not just the currently known
exceptions.

Now the only checked exceptions on Git API calls are GitException and
subclasses of it. New checked exceptions that are subclasses of
GitException may be added without breaking the API.

Javadoc for GitAPIException is declared on GitCommand and
inherited to subclasses. JGitInternalException is not explicitly
documented anymore.

Unfortunately this change itself breaks the API. The intention is
that it shall be possible to add new checked subclasses of
GitAPIException without breaking the API.

Kevin Sawicki 91f5ce3a15 Only increment mod count if packed-refs file changes
Previously if a packed-refs file was racily clean then there
was a 2.5 second window in which each call to getPackedRefs
would increment the mod count causing a RefsChangedEvent to be
fired since the FileSnapshot would report the file as modified.

If a RefsChangedListener called getRef/getRefs from the
onRefsChanged method then a StackOverflowError could occur
since the stack could be exhausted before the 2.5 second
window expired and the packed-refs file would no longer
report being modified.

Now a SHA-1 is computed of the packed-refs file and the
mod count is only incremented when the packed refs are
successfully set and the id of the new packed-refs file
does not match the id of the old packed-refs file.

Robin Rosenberg 42d7565ba9 Validate paths during DirCheckout
DirCacheCheckout and CanonicalTreeParser cooperate. CanonicalTreeParser
can detect malformed, potentially malicious tree entries and sets a
flag, while DirCacheCheckout refuses to work with such paths.

Malicious tree entries are ".", "..", ".git" (case insensitive), any
name containing '/' and (on Windows '\') and also (on Windows)
any paths ending in a combination of '.' or space or containing a ':'.
We also forbid all special names like "con" etc on Windows.

Some of the test can execute on any platform by enabling partial
platform emulation.

A new runtime exception, InvalidPathException, is introduced. For
backwards compatibility it extends InvalidArgumentException.

Auto CRLF isn't special enough to be screwing around with the buffers

buffer to process a file that is bigger than the buffer allocated by
an ObjectInserter, it needs to do its own buffer management.

Kevin Sawicki 9be6526e9d Only unstash files changed when originally stashed
Previously a DirCacheCheckout was done using a merge tree reflecting
the state of the repository when the stash was originally done.
This was wrong since unstashing after making subsequent commits
would undo changes already committed by checking out entries from
an outdated tree.

The new approach is to scan for conflicts initially using a 6-way
tree walk that contains the trees for the stashed HEAD, stashed
index, stashed working directory, current HEAD, current index, and
current working directory.  Then perform a subsequent scan of the
stashed HEAD, index, and working directory trees and apply all
the stashed differences to the current index and working directory.

If after resolving all conflicts nothing is left to commit, return

Currently, EGit displays a "HEAD advanced fast forward" message, which

This is the basic API revamping required to get that state communicated
