Only on Windows the rename operation which renames temporary Packfiles
(and index-files and bitmap-files) sometime fails. This happens only
when renaming a temporary Packfile to a Packfile which already exists.
Such situations occur if you run GC twice on a repo without modifying
the repo inbetween.
In such situations there was bug in GC which led to a corrupted repo
whithout any packfiles anymore. This commit fixes the problem by
introducing a utility method which renames a file and throws an
IOException if it fails. This method also takes care to repeat a
failing rename if our FS class has found out we are running on a
platform with a unreliable File.renameTo() method.
I am searching for a better solution because even with this utility
method in hand a GC on a already GC'ed repo will fail on Windows. But
at least with this fix we will not produce corrupted repos anymore.

With JGit it is possible to write reflog entries where new objectid and
old objectid is null. Such reflogs cause FileRepository GC to crash
because it doesn't expect the new objectid to be null. One case where
this happened is in Gerrit's allProjects repo. In the same way as we
expect the old objectid to be potentially null we should also ignore
null values in the new objectid column.

The bitmap code in PackWriter knows exactly when to use a pack as
a "cached pack". It enables cached pack usage only when the pack
has a bitmap and its entire closure of objects needs to be sent.
This is a much simpler code path to maintain, and JGit actually
has a way to write the necessary index.

Just counting objects is not sufficient. There are some race
conditions with receive packs and delta base completion that
may confuse such a simple algorithm.
Instead always do the larger set computations, and rely on the
PackWriter having no objects pending as the way to avoid creating
an empty pack file.

The walk logic does not use RevWalk because it needs to walk all paths
to each of the requested commits, keeping track of each path along which
the commit was found in the RevCommit subclass. From these paths, a
single "best" path is chosen based on the total path length, with a
penalty applied for paths that traverse merges.
This functionality parallels "git name-rev".

Clients send a bunch of unknown objects to UploadPack on each round
of negotiation. Many of these are not known to the server, which
leads the implementation to be looking at indexes for garbage packs.
Disable examining the index of a garbage pack, allowing servers to
avoid reading them from disk during negotiation.
The effect of this change is the server will only ACK a have line
if the object was reachable during the last garbage collection,
or was recently added to the repository. For most repositories
there is no impact in this behavior change.
If a repository rewinds a branch, runs GC, and then resets the
branch back to where it was before, the now current tip is going to
be skipped by this change. A client that has the commit may wind up
getting a slightly larger data transfer from the server as an older
common ancestor will be chosen during negotiation. This is fixable
on the server side by running GC again to correct the layout of
objects in pack files.

The DHT backend was very slow at parsing objects. To work around
that performance limitation I obfuscated UploadPack by folding both
the want and have sets together in a single parse queue. Since DHT
was removed the complexity is no longer constructive to JGit.
Doing this refactoring prepares the code for a slightly future
change where the have lines need to be handled specially from the
want lines. Splitting the parsing up into two phases makes such
a modification trivial.

Update the PackWriter to support writing out pack bitmap indexes,
a parallel ".bitmap" file to the ".pack" file.
Bitmaps are selected at commits every 1 to 5,000 commits for
each unique path from the start. The most recent 100 commits are
all bitmapped. The next 19,000 commits have a bitmaps every 100
commits. The remaining commits have a bitmap every 5,000 commits.
Commits with more than 1 parent are prefered over ones
with 1 or less. Furthermore, previously computed bitmaps are reused,
if the previous entry had the reuse flag set, which is set when the
bitmap was placed at the max allowed distance.
Bitmaps are used to speed up the counting phase when packing, for
requests that are not shallow. The PackWriterBitmapWalker uses
a RevFilter to proactively mark commits with RevFlag.SEEN, when
they appear in a bitmap. The walker produces the full closure
of reachable ObjectIds, given the collection of starting ObjectIds.
For fetch request, two ObjectWalks are executed to compute the
ObjectIds reachable from the haves and from the wants. The
ObjectIds needed to be written are determined by taking all the
resulting wants AND NOT the haves.
For clone requests, we get cached pack support for "free" since
it is possible to determine if all of the ObjectIds in a pack file
are included in the resulting list of ObjectIds to write.
On my machine, the best times for clones and fetches of the linux
kernel repository (with about 2.6M objects and 300K commits) are

A pack bitmap index is an additional index of compressed
bitmaps of the object graph. Furthermore, a logical API of the index
functionality is included, as it is expected to be used by the
PackWriter.
Compressed bitmaps are created using the javaewah library, which is a
word-aligned compressed variant of the Java bitset class based on
run-length encoding. The library only works with positive integer
values. Thus, the maximum number of ObjectIds in a pack file that
this index can currently support is limited to Integer.MAX_VALUE.
Every ObjectId is given an integer mapping. The integer is the
position of the ObjectId in the complete ObjectId list, sorted
by offset, for the pack file. That integer is what the bitmaps
use to reference the ObjectId. Currently, the new index format can
only be used with pack files that contain a complete closure of the
object graph e.g. the result of a garbage collection.
The index file includes four bitmaps for the Git object types i.e.
commits, trees, blobs, and tags. In addition, a collection of
bitmaps keyed by an ObjectId is also included. The bitmap for each entry
in the collection represents the full closure of ObjectIds reachable
from the keyed ObjectId (including the keyed ObjectId itself). The
bitmaps are further compressed by XORing the current bitmaps against
prior bitmaps in the index, and selecting the smallest representation.
The XOR'd bitmap and offset from the current entry to the position
of the bitmap to XOR against is the actual representation of the entry
in the index file. Each entry contains one byte, which is currently
used to note whether the bitmap should be blindly reused.

CloneCommand has been creating fetch refspecs like this on bare clones:
[remote "origin"]
url = ssh://example.com/my-repo.git
fetch = +refs/heads/*:refs/heads//*
As you can see, the destination ref pattern has a superfluous slash.
It looks like this behaviour has always been the case for CloneCommand,
at least since cc2197ed when code catering to bare-clone fetch refspecs
was added. That was released with JGit v1.0 almost 2 years ago, so
there will probably be some bare repos in the wild which will have been
cloned with JGit and have these corrupted refspecs.
The effect of the corrupted fetch refspec is quite interesting. Up to
and including JGit 2.0, the corrupt refspec was tolerated and fetches
would work as intended with no indication to the user that anything was
amiss. With JGit 2.1, a change was introduced which made JGit less
tolerant, and fetches now attempt to update the non-existing ref
"refs/heads//master". No exception is raised, but the real ref -
"refs/heads/master" - is not updated.
This behaviour was noticed by a user of Agit (which does bare clones by
default and recently updated from JGit v2.0 to v2.2), reported here:
https://github.com/rtyley/agit/issues/92
If you run C-Git fetch on a bare-repo cloned by JGit, it flat-out
rejects the refspec (checked against v1.7.10.4):
fatal: Invalid refspec '+refs/heads/*:refs/heads//*'
Incidentally, C-Git does not create an explicit fetch refspec at all
when performing a bare clone - the full remote config generated by C-Git
looks like this:
[remote "origin"]
url = ssh://example.com/my-repo.git
Using JGit on such a repository works fine, so omitting the fetch
refspec entirely is also an option.

No longer invoke the expensive RefDatabase.isNameConflicting() check on
updating existing refs, reducing batch ref update time by ~97%.
The RefDirectory implementation of isNameConflicting() is quite
slow (it has to do an expensive loose-ref scan) but it's only necessary
to perform this check on ref update if the ref is being *created* - if
the ref already exists, we can already guarantee that it does not
conflict with any other refs.
C-Git seems to use a similar condition before making the
is_refname_available() check:
https://github.com/git/git/blob/v1.8.1.4/refs.c#L1660-L1670
As an example of the effects on performance, here's a simple timing
experiment using The BFG to remove one file from the JGit repo:
---
$ wget http://repo1.maven.org/maven2/com/madgag/bfg-repo-cleaner/1.0.1/bfg-1.0.1.jar
$ git clone --mirror https://git.eclipse.org/r/p/jgit/jgit.git
$ java -jar bfg-1.0.1.jar -D make_jgit.sh jgit.git
....
Updating references: 100% (5760/5760)
...Ref update completed in 148,949 ms.
BFG run is complete!
---
The execution time for the run is completely dominated by the batch ref
update at the end. Repeating the experiment with BFG v1.0.2 (using JGit
patched with this change), the refs update is dramatically reduced:
---
Updating references: 100% (5760/5760)
...Ref update completed in 4,327 ms.

When a lot of commits are added to DateRevQueue, the
sort-on-insertion approach is very heavy on CPU cycles.
One approach to fix this was made by Dave Borowitz:
https://git.eclipse.org/r/#/c/5491/
But using Java's PriorityQueue seems to have brought some
extra overhead, and the desired performance could not be
reached.
This fix takes another approach to the insertion problem,
without changing the expected behaviour or bringing extra
memory overhead:
If we detect over 1000 commits in the DateRevQueue, a
"seek-index" is rebuilt every 1000th added commit.
The index keeps track of every 100th commit in the
DateRevQueue. During insertions, it will be used for a
preliminary scanning (binary search) of the queue, with
the intention of helping add() find a good starting point
to start walking from. After finding this starting point,
add() will step commit-by-commit until the correct
insertion place in the queue is found (today, the queue
is expected to be sorted at all times).
When applied to repositories with many refs, this approach
has proven to bring huge performance gains and scales quite
well.
For instance, in a repository with close to 80000 refs,
we could cut down the time a typical Gerrit replication
of 1 commit would take (just a push from JGit's point of
view) from 32sec down to 3.5sec.
Below you see some typical times to add a specific amount
of commits (with random commit times) to the DateRevQueue
and the difference the preliminary seek-index makes:
Commits | Index | No Index
1024 8ms 8ms
2048 13ms 9ms
4096 5ms 59ms
8192 11ms 595ms
16384 22ms 3058ms
32768 64ms 13811ms
65536 201ms 62677ms
131072 783ms 331585ms
Only one extra reference is needed for every 100 inserted
commits (and only when we see more than 1000 commits in
the queue), so the memory overhead should be negligible.
Various index-stepping values were tested, and 100 seemed to
scale very well and be effective from start.
In the future, it should probably be dynamic and based on
the number of refs in the queue, but this should serve well
as a starting point.
Note: While other fundamentally different data structures may
be more suitable, the DateRevQueue is extremely central to
many of the Git core operations. This approach was chosen,
since the effect of the patch is easy to predict in conjuction
with the current implementation. A totally new data structure
will make it harder to predict behaviour in many common and
uncommon cases (in terms of breaking ties, memory usage, cost
when using few elements, object creation/disposing overhead,
etc).

There is a huge performance issue when using both JGit (EGit) and Git
because JGit does not fill all dircache stat fields with the values Git
would expect. As a result thereof Git would typically revalidate a large
number of tracked files. This can take several minutes for large
repositories with many large files.
Since 1.8.2 Git will restrict stat checking to the size and whole second
part of the modification time stamp, if core.statinfo is set to
"minimal".
As JGit checks only size and modification time this is close to what
JGit already does. To make the match perfect ignore the sub-second part
of the modification time stamp if core.statinfo = minimal.

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:

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.

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.

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)

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.

a Git API should catch GitAPIException and not just the currently known

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

Unfortunately this change itself breaks the API. The intention is
that it shall be possible to add new checked subclasses of

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.

Previously the index was cleared and updated with a new tree.
Now the commit being reset to and the index are iterated over
in a tree walk and the current index mod time and file length
are copied over to the new dir cache entry being written if
the object ids are the same.

Overload DirCache.lock to take a repository that is
used for updating smudged index entries with information
from the repository's working tree.
New unit tests are also added for updating smudged index
entries on reset, checkout, and commit.

When reset command was called with tag name as parameter the resulting
HEAD was set to the tag's SHA-1 which is a bug. This patch ensures that
repository.resolve() call always returns commit id.

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.

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.

If BaseReceivePack has setAllowNonFastForwards(false) configured
(such as by receive.denynonfastforwards), automatically reject
any command that attempts a non-fast-forward update before it goes
further in processing.
This matches with other checks in validateCommands(), such as the
early failure of delete attempts when isAllowDeletes() is false.

That happens when the index and a new file is created within the same
second and becomes a problem if we then modify the newly created file
within the same second after adding it to the index. Without smudging
JGit will, on later reads, think the file is unchanged.
The accompanying test passed with the smuding on read.

"Auth fail" exception was swallowed during retrying, this leads to
"Session down" exception during clone operation with invalid SSH keys.

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
packs received on a single open connection. So, hoist out as much as we
can from ReceivePack, mostly just leaving behind the single-connection
version in that class.

'mergeStrategy' should be 5th argument, after 'mergeStatus'. Pass
'description' if available.

This method only creates an EolCanonicalizingInputStream
which does not throw an IOException and so the throws
declaration on the method is unneeded.
