A set of ref names like ('a/b' and 'a+b') would cause the RefDirectory
to think that the set of refs have changed because it traversed the
'a' directory in the subtree before looking at 'a+b', but it then
compared with the know refs which are sorted with 'a+b' first.
Fix this by traversing the refs tree in another order. Treat a directory
as if they ends with a '/' before deciding on the order to traverse
the refs tree.

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.

Some servlet containers require the servlet to read the EOF marker
from the input stream before a response can be output if the stream
is using "Transfer-Encoding: chunked"... which is typical for any
sort of large push to a repository over smart HTTP.
Ensure the EOF is always read by the PackParser when it is handling
the stream, and fail fast if there is more data present than expected
since this does indicate a protocol error.
Also ensure the EOF is read by UploadPack before it starts to output
a partial response using packing progress meters.

Some repositories created during tests are not added to the 'toClose'
list in LocalDiskRepositoryTestCase. Therefore when the tests end
we may have open FileHandles and on Windows this may cause the
tests to fail because we can't delete those files.
This is fixed by adding the possibility to explicitly add
repositories to the list of repos which are closed automatically.

When cloning into a bare repository we should not create remote
tracking branches (e.g refs/remotes/origin/testX). Branches of the
remote repository should but fetched into into branches of the same
name (e.g refs/heads/testX). Also add the noCheckout option which
would prevent checkout after fetch.

Since this change may affect performance and memory consumption on every
access to a loose ref I explicitly made it a RFC to collect opinions.
Previously RefDirectory.scanRef() was not detecting an update of a
loose ref when the update didn't changed the modification time of
the backing file. RefDirectory cached loose refs and the way to detect
outdated cache entries was to compare lastmodification timestamp on the
file representing the ref. If two updates to the same ref happen faster
than the filesystem-timer granularity (for linux this is 2 seconds)
there is the possiblity that we don't detect the update.
Because of this bug EGit's PushOperationTest only works with 2 second
sleeps inside.
This change let RefDirectory use FileSnapshot to detect such situations.
FileSnapshot helps to remember when a file was last read from disk and
therefore enables to decide when to load a file from disk although
modification time has not changed.

Previously when merging two contents with a non-empty base and one of
the contents was empty (size == 0) and the other was modified there
was a potentially expensive calculation until we finally always come
to the same result -> the complete non-deleted content should collide
with the empty content.
This proposal adds an optimization to detect empty input content and
to produce the appropriate result immediatly.

RefDirectory did not correctly follow the contract of RefList. The
contract says if you use add() method of RefList builder, you MUST
sort() it afterwards, and later every other method assumes that list
is properly sorted (especially the binary search in the find() and
get() methods). Instead RefDirectory class tried to scan the refs
recursively while sorting every folder in the process before
processing and did not call sort().
For example, when scanning the contents of refs/tags project1 string
is smaller than project1-*, so it will recursively go into the folder
and add these tags first and only then will add project-* ones. This
will result in a broken list (any project1-* string is less than
project1/* one, but they all appear after them in the list), that's
why binary search will fail making loose RefList and the whole local
RefMap completely unusable.

Add handling of CHERRY_PICK_HEAD file in .git (similar to MERGE_HEAD),
which is written in case of a conflicting cherry-pick merge.
It is used so that Repository.getRepositoryState can return the new
states CHERRY_PICKING and CHERRY_PICKING_RESOLVED. These states, as well
as CHERRY_PICK_HEAD can be used in EGit to properly show the merge tool.
Also, in case of a conflict, MERGE_MSG is written with the original
commit message and a "Conflicts" section appended. This way, the
cherry-picked message is not lost and can later be re-used in the commit
dialog.
