Previously the result of an application would have been \r\r\n in the
case of windows line endings, as RawText does not touch the \r, and
ApplyCommand adds "\r\n" if this is the ending of the first line in the
target file. Only always adding \n should be ok, since \r\n would be the
result if the file and the patch include windows line endings.

Previously, the Dfs GC excluded objects from packs by passing a

Dfs is slow. Instead, allow the PackWriter to expose the objects

The primary purpose of the filter is to detect an index change that
could possibly lead to a change in what files are visible in the staging
view and decorations. Besides what TreeFilter.ANY_DIFF does for trees in

see whether changes should be ignored or not.

If multiple threads attempted to insert loose objects into the same new
fan-out directory, the creation of that directory was subject to a race
condition that could lead to an unnecessary IOException being thrown -
because an inserter could not 'create' a directory that had just been
generated by a different thread. All we require is that the directory
does indeed *exist*, so not being able to _create_ it is not actually a
fatal problem. Setting 'skipExisting' to 'true' on the call to mkdir()
fixes the issue.
I found this issue as a real world occurrence while working on The BFG
Repo Cleaner (https://github.com/rtyley/bfg-repo-cleaner), a tool which
concurrently performs a lot of object creation.
In order to demonstrate the problem here I've added a small test case
which reliably reproduces the issue on the few different hardware
systems I've tried. The error thrown when the race-condition arises is
this:

- Clear revert state on commit and reset
- Format the message similarily to how cherry-pick does. This is
not exactly how C Git does it.

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

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)

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.

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

=======
b
>>>>>>> b161dea Message of a commit I'm rebasing

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.

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)

Repository.resolve can only return an ObjectId and 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".

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.

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.

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.

ResolveMerger#mergeImpl() was only returning false (= failed) when there
were unmerged paths. In the case when there were only failing paths, it

Because MergeCommand looks at the return value for determining if the

should instead return a MergeResult with MergeStatus.FAILED.
This change adds a test case for this and makes the ResolveMerger return

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.

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.

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.

If there are a lot of references to modify, using BatchRefUpdate can
save time if the underlying storage is able to combine these updates
together. This should speed up initial clone or fetch into an empty
repository, as some projects can have hundreds of release tags, or
hundreds of branch heads.
Change-Id: Iee9af8d5fa19080077d88357c18853540936e940
clone, fetch and push can all update multiple references in a single
command invocation. Rather than performing sequential iteration
of each reference change inside of the application code, push this
down into the reference database where the implementation can take
advantage of the batch size and optimize itself.
For the local filesystem implementation the obvious optimization
is to write a packed-refs file when the repository is completely
empty. The initial clone, fetch or push into the destination may
have hundreds of new references. Writing all of these as loose
files is not efficient. This optimization is not implemented in
this commit and is left as an exercise for the reader to supply
in a future commit to JGit.
To make the API changes simple, define the BatchRefUpdate type and
implementation using the existing sequential behavior.

When a command's type is UPDATE, JGit might not yet be sure if it
is a fast-forward or not. Expose a utility method to compute the
exact type by performing the merge base test, allowing the type
to be switched to UPDATE_NONFASTFORWARD if old ObjectId is not
contained in new ObjectId.
BaseReceivePack already does this test when validating the incoming
command list, so provide a package level backdoor to set the type
and avoid needing to redo the merge test later.

We are working on a publish/subscribe based git protocol, and we want to
reuse several parts of the ReceivePack-like code for reading commands
and processing a pack. In this new implementation, the connection
management will be very different, in particular, there may be multiple

can from ReceivePack, mostly just leaving behind the single-connection

Parsing the size from a packed object header was incorrectly computing
the total inflated length when the length exceeded the range of a Java
int. The next 7 bits of size information was shifted left as an int
using a shift of 25 bits, placing the higher bits of the size into the
sign position. When this size was extended to a long to be added to
the current size accumulator the size went negative, resulting in
NegativeArraySizeException being thrown.
Fix all places where this particular pattern of code is used to read a
pack size field, or a binary delta header, as they both use the same
variable length encoding scheme.

Decrease running time for getStringList (and all other get methods) by
looking for configuration entries using binary search rather than
linear search through the configuration file.
Configuration lines are sorted by section, subsection, name in a
sorted list whenever the snapshot is rebuilt. Binary search is used to
locate an index in the middle of the values, then walk backwards to
find the first value in the range.
Given a configuration of file of 5000 distinct section/subsection/name
triplets (e.g. a Gerrit Code Review project.config configuration file
with 5000 unique access control rules), this new code is faster to
lookup each rule individually using getStringList():
old setStringList() 194 usec avg
getStringList() 196 usec avg
new setStringList() 188 usec avg
getStringList() 24 usec avg

Recently Robin tried to increase the size of the buffer used by
ObjectInserter to fix a bug in the InputStream that handles AutoCRLF.
The purpose of this buffer is NOT to make a random InputStream work
correctly by passing it a larger buffer during read(byte[],int,int).
Clarify the Javadoc on the buffer() method to reduce the risk
someone tries to abuse it again.
While we are here, modify the method to load the field into a local
variable before returning. This should cut down 1 field load during
the common case of the buffer being already allocated.

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.

When fetching over smart HTTP the InputStream that gets fed into
a PackParser doesn't really support EOF at the end of the pack. It
instead tries to make a new HTTP request, which fails because there
is no request body currently buffered by the client.
Make EOF work correctly on the end of an HTTP derived InputStream
for the pack by denoting no more requests are expected as the higher
level code is now consuming the pack (or side-band embedded pack).
Smart HTTP support doesn't automatically enqueue execute support onto
the end of the UnionInputStream, which allows the UnionInputStream
to correctly reflect EOF when the HTTP response is consumed.
