Enable marking entries using TreeFilters in DiffEntry
This adds a new optional TreeFilter[] argument to DiffEntry.scan. All
filters will be checked during the scan to determine if an entry should
be "marked" with regard to that filter.
After having called scan, the user can then call isMarked(int) on the
entries to find out whether they matched the TreeFilter with the passed
index.
An example use case for this is in the file diff viewer of EGit's
History view, where we'd like to highlight entries that are matching the
current filter.
See EGit change I03da4b38d1591495cb290909f0e4c6e52270e97f.

Update DfsGarbageCollector to not read back a pack index.
Previously, the Dfs GC excluded objects from packs by passing a
previously written index to the PackWriter. Reading back a file on
Dfs is slow. Instead, allow the PackWriter to expose the objects
included in a pack and forward that to invocations of excludeObjects() .

Update the revert command and things relating to revert
Cherry-pick has been fixed, but even though revert does
basically the same thing, the fixes were not carried over here.
- Recognize the revert-states, analogous to the cherry picking states
- Make reset handle a revert-in-progress
- Update REVERT_HEAD and MERGE_MSG when revert fails due to conflicts
- 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.
The interface is still not the same as for cherry-picking.

Simplify push error message when ref already exists
If a client attempts to create a branch that already exists on the
remote side, tell them "already exists" rather than repeat lots of
information about the reference. Previously the error looked like:
! [remote rejected] tags/1.3.1 -> 1.3.1 (Ref Ref[refs/tags/1.3.1=e3857ee05...] already exists)
Now it will simply say:
! [remote rejected] tags/1.3.1 -> 1.3.1 (already exists)

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)

Read .gitmodules config from the tree in SubmoduleWalk
It is not always appropriate to use the .gitmodules file from the
working tree, for example if reading the modules at a specific commit.
And sometimes it is impossible, as in a bare repository.
When using the static factory methods, automatically set up the
appropriate root tree so lazy loading of the config file reads from
the appropriate place. Leave the current behavior of looking in the
working tree as a fallback for the case where walking the index.

This extracts the logic for writing to the reflog from
RefDirectory into a new ReflogWriter class. This class
creates a public API for writing reflog entries similar

The new command supports rewriting the stash's log to remove
a configured entry followed by updating the stash ref to
the value at the bottom of the newly written log.

as a ref to a folder located elsewhere. This supports submodules

ReceivePack (and PackParser) can be configured with the
maxObjectSizeLimit in order to prevent users from pushing too large
objects to Git. The limit check is applied to all object types
although it is most likely that a BLOB will exceed the limit. In all
cases the size of the object header is excluded from the object size
which is checked against the limit as this is the size of which a BLOB
object would take in the working tree when checked out as a file.
When an object exceeds the maxObjectSizeLimit the receive-pack will
abort immediately.
Delta objects (both offset and ref delta) are also checked against the
limit. However, for delta objects we will first check the size of the
inflated delta block against the maxObjectSizeLimit and abort
immediately if it exceeds the limit. In this case we even do not know
the exact size of the resolved delta object but we assume it will be
larger than the given maxObjectSizeLimit as delta is generally only
chosen if the delta can copy more data from the base object than the
delta needs to insert or needs to represent the copy ranges. Aborting
early, in this case, avoids unnecessary inflating of the (huge) delta
block.
Unfortunately, it is too expensive (especially for a large delta) to
compute SHA-1 of an object that causes the receive-pack to abort.
This would decrease the value of this feature whose main purpose is to
protect server resources from users pushing huge objects. Therefore
we don't report the SHA-1 in the error message.

If an internal exception occurs while packing and the request
needs to abort, the HTTP response might already be committed due
to progress message having already been delivered to the client.
This prevents UploadPackServlet from resetting the response and
sending back an HTTP 500 response.
Try to catch all exceptions and report internal errors over the
sideband stream or as an ERR command during the initial ACK/NAK
negotiation phase. This allows JGit to transmit an error message
that the user will receive on their console without needing to

If a fetch or push needs to apply more than a few references
to the local repository it may take more than 0.25 seconds to
process all of the updates. This is especially true in the DHT
storage system during an initial push of a project with many tags.
The backend database may need to use a transaction to ensure each
tag reference creation is unique, and there may be large delays
caused by these transactions.

blame: Compute the origin of lines in a result file
BlameGenerator digs through history and discovers the origin of each
line of some result file. BlameResult consumes the stream of regions
created by the generator and lays them out in a table for applications
to display alongside of source lines.
Applications may optionally push in the working tree copy of a file
using the push(String, byte[]) method, allowing the application to
receive accurate line annotations for the working tree version. Lines
that are uncommitted (difference between HEAD and working tree) will
show up with the description given by the application as the author,
or "Not Committed Yet" as a default string.
Applications may also run the BlameGenerator in reverse mode using the
reverse(AnyObjectId, AnyObjectId) method instead of push(). When
running in the reverse mode the generator annotates lines by the
commit they are removed in, rather than the commit they were added in.
This allows a user to discover where a line disappeared from when they
are looking at an older revision in the repository. For example:
blame --reverse 16e810b2..master -L 1080, org.eclipse.jgit.test/tst/org/eclipse/jgit/storage/file/RefDirectoryTest.java
( 1080) }
2302a6d3 (Christian Halstrick 2011-05-20 11:18:20 +0200 1081)
2302a6d3 (Christian Halstrick 2011-05-20 11:18:20 +0200 1082) /**
2302a6d3 (Christian Halstrick 2011-05-20 11:18:20 +0200 1083) * Kick the timestamp of a local file.
Above we learn that line 1080 (a closing curly brace of the prior
method) still exists in branch master, but the Javadoc comment below
it has been removed by Christian Halstrick on May 20th as part of
commit 2302a6d3. This result differs considerably from that of C
Git's blame --reverse feature. JGit tells the reader which commit
performed the delete, while C Git tells the reader the last commit
that still contained the line, leaving it an exercise to the reader
to discover the descendant that performed the removal.
This is still only a basic implementation. Quite notably it is
missing support for the smart block copy/move detection that the C
implementation of `git blame` is well known for. Despite being
incremental, the BlameGenerator can only be run once. After the
generator runs it cannot be reused. A better implementation would
support applications browsing through history efficiently.
In regards to CQ 5110, only a little of the original code survives.
