During fetch over http:// clients now try to take advantage of
the info/refs?service=git-upload-pack URL to determine if the
remote side will support a standard upload-pack command stream.
If so each block of 32 have lines is sent in one POST request,
prefixed by all of the 'want' lines and any previously discovered
common bases as 'have' lines.
During push over http:// clients now try to take advantage of
the info/refs?service=git-receive-pack URL to determine if the
remote side will support a standard receive-pack command stream.
If so, commands are sent along with their pack in a single HTTP
POST request.

This is a simple HTTP server that provides the minimum server side
support required for dumb (non-git aware) transport clients.
We produce the info/refs and objects/info/packs file on the fly
from the local repository state, but otherwise serve data as raw
files from the on-disk structure.
In the future we could better optimize the FileSender class and the
servlets that use it to take advantage of direct file to network
APIs in more advanced servlet containers like Jetty.
Our glue package borrows the idea of a micro embedded DSL from
Google Guice and uses it to configure a collection of Filters
and HttpServlets, all of which are matched against requests using
regular expressions. If a subgroup exists in the pattern, it is
extracted and used for the path info component of the request.

By making this class and its methods public, and the actual writing
abstract, we can reuse this code for other formats like writing an

If biDirectionalPipe is false UploadPack does not start out with
the advertisement but instead assumes it should read one block of
want/have lines, process that, and write the ACK/NAKs out.
This means it only is doing one read through the input followed by
one write to the output, which fits with the HTTP request processing
model, and any other type of RPC system.

If biDirectionalPipe is false ReceivePack does not start out with the

process that, and write the status report out. This means it only is
doing one read through the input followed by one write to the output,
which fits with the HTTP request processing model, and any other type

entity like the command stream followed by the pack file.

Later we are going to add support for smart HTTP, which requires us to
buffer at least some of the request created by a client before we ship
it to the server. For many requests, we can fit it completely into a
1 MiB buffer, but if it doesn't we can drop back to using the chunked
transfer encoding to send an unknown stream length.
Rather than recoding the block based memory buffer, we refactor the
local file overflow strategy into a subclass, allowing the HTTP client
code to replace this portion of the logic with its own approach to
start the chunked encoding request.

Deflater can use significant amount of native (i.e. C) heap
space. Failure to promptly release this memory results
in native memory leak in some cases, particularly severe for
VMs with large java max heap size. For example, running
Team->Commit in one of my EGit workspaces results in ~500M
java process size increase without any significant change
to amount of used java heap when JVM is started with -Xmx1024m.

Adds the file content merge alorithm and tests for merge to jgit.
The merge algorithm:
- Gets as input parameters the common base, the two new contents
called "ours" and "theirs".
- Computes the Edits from base to ours and from base to theirs with
the help of MyersDiff.
- Iterates over the edits.
- Independent edits from ours or from theirs will just be applied
to the result.
- For conflicting edits we first harmonize the ranges of the edits
so that in the end we have exactly two edits starting and ending
at the same points in the common base. Then we write the two
conclicting contents into the result stream.

GIT_INDEX_FILE

GIT_CEILING_DIRECTORIES

which JGit will not cross when looking for the .git directory.
GIT_OBJECT_DIRECTORY
The location of the objects directory under which objects are

GIT_ALTERNATE_OBJECT_DIRECTORIES

This new UI bundle contains the org.eclipse.jgit.awtui package,
which was moved out of the org.eclipse.jgit bundle.
org.eclipse.jgit.pgm depends on org.eclipse.jgit.ui, so we need
to update the classpath and make_jgit.sh to include it.
This move takes the awtui classes out of the Maven build, which
means we are no longer able to distribute these classes to our

needs to be overhauled so that Eclipse bundle matches 1:1 with the

This change only fixes warnings of the eclipse build regarding missing javadocs.
Some comments where just missing, so they have been added. Other comments where
at the wrong (from eclipse point of view) place, so eclipse was complaining.
Also two method which existed for debugging purposes have been removed to get
rid of Eclipse warngins about unused code.
MyersDiff was crashing with ArrayIndexOutOfBoundsException when
diffing huge files. This was because the snake data (begin and
end position while processing chunks of the text) was sequeezed
into a single int. But with longer texts to diff these values
exceeded the range of java int values. It is fixed by squeezing
the two ints into a long and by adding the LongList helper
class.

Honor the configuration parameter core.logAllRefUpdates when writing

reflogs if this parameter is set to true or if the corresponding

if you are updating a ref and this parameter is set to false and
there is no file corresponding to your ref in the <git-dir>/logs
folder then no reflog will be written.
