smart-http: Fix recognition of gzip encoding
Some clients coming through proxies may advertise a different

Matching by substring causes us to identify this as a false positive;
that the client understands gzip encoding and will inflate the

In this particular case however it doesn't. Its the reverse proxy
server in front of JGit letting us know the proxy<->JGit link can
be gzip compressed, while the client<->proxy part of the link is not:
client <-- no gzip --> proxy <-- gzip --> JGit
Use a more standard method of parsing by splitting the value into

PackWriter: Support reuse of entire packs
The most expensive part of packing a repository for transport to
another system is enumerating all of the objects in the repository.
Once this gets to the size of the linux-2.6 repository (1.8 million
objects), enumeration can take several CPU minutes and costs a lot
of temporary working set memory.
Teach PackWriter to efficiently reuse an existing "cached pack"
by answering a clone request with a thin pack followed by a larger
cached pack appended to the end. This requires the repository
owner to first construct the cached pack by hand, and record the
tip commits inside of $GIT_DIR/objects/info/cached-packs:
cd $GIT_DIR
root=$(git rev-parse master)
tmp=objects/.tmp-$$
names=$(echo $root | git pack-objects --keep-true-parents --revs $tmp)
for n in $names; do
chmod a-w $tmp-$n.pack $tmp-$n.idx
touch objects/pack/pack-$n.keep
mv $tmp-$n.pack objects/pack/pack-$n.pack
mv $tmp-$n.idx objects/pack/pack-$n.idx
done
(echo "+ $root";
for n in $names; do echo "P $n"; done;
echo) >>objects/info/cached-packs
git repack -a -d
When a clone request needs to include $root, the corresponding
cached pack will be copied as-is, rather than enumerating all of
the objects that are reachable from $root.
For a linux-2.6 kernel repository that should be about 376 MiB,
the above process creates two packs of 368 MiB and 38 MiB[1].
This is a local disk usage increase of ~26 MiB, due to reduced
delta compression between the large cached pack and the smaller
recent activity pack. The overhead is similar to 1 full copy of
the compressed project sources.
With this cached pack in hand, JGit daemon completes a clone request
in 1m17s less time, but a slightly larger data transfer (+2.39 MiB):
Repository owners can periodically refresh their cached packs by
repacking their repository, folding all newer objects into a larger
cached pack. Since repacking is already considered to be a normal
Git maintenance activity, this isn't a very big burden.
[1] In this test $root was set back about two weeks.

RefAdvertiser: Avoid object parsing
It isn't strictly necessary to validate every reference's target
object is reachable in the repository before advertising it to a
client. This is an expensive operation when there are thousands of
references, and its very unlikely that a reference uses a missing
object, because garbage collection proceeds from the references and
walks down through the graph. So trying to hide a dangling reference
from clients is relatively pointless.
Even if we are trying to avoid giving a client a corrupt repository,
this simple check isn't sufficient. It is possible for a reference to
point to a valid commit, but that commit to have a missing blob in its
root tree. This can be caused by staging a file into the index,
waiting several weeks, then committing that file while also racing
against a prune. The prune may delete the blob, since its
modification time is more than 2 weeks ago, but retain the commit,
since its modification time is right now.
Such graph corruption is already caught during PackWriter as it
enumerates the graph from the client's want list and digs back
to the roots or common base. Leave the reference validation also
for that same phase, where we know we have to parse the object to
support the enumeration.

PackWriter: Make thin packs more efficient
There is no point in pushing all of the files within the edge
commits into the delta search when making a thin pack. This floods
the delta search window with objects that are unlikely to be useful
bases for the objects that will be written out, resulting in lower
data compression and higher transfer sizes.
Instead observe the path of a tree or blob that is being pushed
into the outgoing set, and use that path to locate up to WINDOW
ancestor versions from the edge commits. Push only those objects
into the edgeObjects set, reducing the number of objects seen by the
search window. This allows PackWriter to only look at ancestors
for the modified files, rather than all files in the project.
Limiting the search to WINDOW size makes sense, because more than
WINDOW edge objects will just skip through the window search as
none of them need to be delta compressed.
To further improve compression, sort edge objects into the front
of the window list, rather than randomly throughout. This puts
non-edges later in the window and gives them a better chance at
finding their base, since they search backwards through the window.
These changes make a significant difference in the thin-pack:
The resulting pack is 13.63 MiB smaller, even though it contains the
same exact objects. 82,543 fewer objects had to have their sizes
looked up, which saved about 8s of server CPU time. 2,796 more
objects from the client were used as part of the base object set,
which contributed to the smaller transfer size.

I regret adding this feature to the public API. Caches aren't always
the best idea, as they require work to maintain. Here the cache is
redundant information that must be computed, and when it grows stale
must be removed. The redundant information takes up more disk space,
about the same size as the pack-*.idx files are. For the linux-2.6
repository, that's more than 40 MB for a 400 MB repository. So the
cache is a 10% increase in disk usage.
The entire point of this cache is to improve PackWriter performance,
and only PackWriter performance, and only when sending an initial

until we have a solid solution, we shouldn't be using a separate cache

Teach PackWriter how to reuse an existing object list
Counting the objects needed for packing is the most expensive part of
an UploadPack request that has no uninteresting objects (otherwise
known as an initial clone). During this phase the PackWriter is
enumerating the entire set of objects in this repository, so they can
be sent to the client for their new clone.
Allow the ObjectReader (and therefore the underlying storage system)
to keep a cached list of all reachable objects from a small number of
points in the project's history. If one of those points is reached
during enumeration of the commit graph, most objects are obtained from
the cached list instead of direct traversal.
PackWriter uses the list by discarding the current object lists and
restarting a traversal from all refs but marking the object list name
as uninteresting. This allows PackWriter to enumerate all objects
that are more recent than the list creation, or that were on side
branches that the list does not include.
However, ObjectWalk tags all of the trees and commits within the list
commit as UNINTERESTING, which would normally cause PackWriter to
construct a thin pack that excludes these objects. To avoid that,
addObject() was refactored to allow this list-based enumeration to
always include an object, even if it has been tagged UNINTERESTING by
the ObjectWalk. This implies the list-based enumeration may only be
used for initial clones, where all objects are being sent.
The UNINTERESTING labeling occurs because StartGenerator always
enables the BoundaryGenerator if the walker is an ObjectWalk and a
commit was marked UNINTERESTING, even if RevSort.BOUNDARY was not
enabled. This is the default reasonable behavior for an ObjectWalk,
but isn't desired here in PackWriter with the list-based enumeration.
Rather than trying to change all of this behavior, PackWriter works
around it.
Because the list name commit's immediate files and trees were all
enumerated before the list enumeration itself starts (and are also
within the list itself) PackWriter runs the risk of adding the same
objects to its ObjectIdSubclassMap twice. Since this breaks the
internal map data structure (and also may cause the object to transmit
twice), PackWriter needs to use a new "added" RevFlag to track whether
or not an object has been put into the outgoing list yet.

By moving the logic that parses a pack stream from the network (or
a bundle) into a type that can be constructed by an ObjectInserter,
repository implementations have a chance to inject their own logic
for storing object data received into the destination repository.
The API isn't completely generic yet, there are still quite a few
assumptions that the PackParser subclass is storing the data onto
the local filesystem as a single file. But its about the simplest
split of IndexPack I can come up with without completely ripping
the code apart.

Parse RevCommit bodies before calling RevFilter.include()
RevFilter.include()'s documentation promises the RevCommit's
body is parsed before include is invoked. This wasn't always
true if the commit was parsed once, had its body discarded,
the RevWalk was reset() and started a new traversal.

Exposed the constructor of Note class
Additionally, defined the NoteMap.getNote method which returns a Note
instance. These changes were necessary to enable implementation of
the NoteMerger interface (the merge method needs to instantiate a
Note) and to enable direct use of NoteMerger which expects instances
of Note class as its paramters. Implementing creation of code review
summary notes in Gerrit [1] will make use of both of these features.

Introduce metaData compare between working tree and index entries
Instead of offering only a high-level isModified() method a new
method compareMetadata() is introduced which compares a working tree entry
and a index entry by looking at metadata only. Some use-cases
(e.g. computing the content-id in idBuffer()) may use this new method
instead of isModified().

File utility for creating a new empty file
The java.io.File.createNewFile() method for creating new empty files
reports failure by returning false. To ease proper checking of return

Fix API ListBranchCommand for listmode 'all'
If remote branches are present they can not be added
to the RefMap from the local branches - the two RefMaps
have a different value of 'prefix' and consequently an
IllegalArgumentException is thrown.

Using java.util.concurrent in NLSTest instead of handling threads directly.
A test in NLSTest was mixing the "old" and the "new" way of handling
concurrency. This change makes use of the java.util.concurrent facilities to
control concurrency and removes the code that was directly dealing with Thread
objects.
