git-core has supported this for a long time; allowing clients to
avoid progress messages from the server if they are dumping to a
pipe instead of a tty.
Avoid the two progress monitors going on side-band and expose
isQuiet() method to allow hooks to also reduce their output if
this is sensible for them.

In 77030a5e, AutoClosable was implemented on classes that use release().
This caused a resource leak because the ObjectReader.close method was
not calling the now deprecated release method, which is the method that
sub classes implements to release resources.

Allow ObjectWalk to be filtered by an arbitrary predicate
This will make it possible to declare a collection of objects as
ineligible for the walk en masse, for example if they are known to be
uninteresting via a bitmap.

The Java GC doesn't always clear these before running out of memory
and failing allocations. In practice OpenJDK 7 is leaving these live,
removing any advantage of the SoftReference to attempt to shed memory
when the GC is unable to continue allocating.
Instead follow the pattern of the DfsBlockCache and use hard refs
to the object data. Require applications to configure the cache
size more accurately given expected memory usage.

The LRU chain management code was broken leading to situations where
the chain was incomplete. This prevented the cache from removing
items when it exceeded its memory target, causing a leak.
One case was repeated hit on the head of the chain. moveToHead(e)
was invoked linking the head back to itself in a cycle orphaning
the rest of the table.
Add some unit tests to cover this and a few other paths.

Use ANY_DIFF filter in ResolveMerger only for bare repositories
As Chris pointed out change I822721c76c64e614f87a080ced2457941f53adcd
slowed down merge since ANY_DIFF filter is much less efficient than the
manual detection of diffs done in ResolveMerger.processEntry() since it
avoids unnecessary filesystem calls using the git index. Hence only set
the ANY_DIFF filter on bare repositories which don't have a working tree
to scan.
To test performance I used the setup described in Chris' comment on
change I822721c76c64e614f87a080ced2457941f53adcd and modified
ResolveMerger.mergeTrees() to not add the working tree in order to
simulate merging in a bare repository.
At least on Mac I couldn't detect a speedup, with and without the
ANY_DIFF filter merge test takes an average 0.67sec.

FS_POSIX: Rework umask detection to make it settable
Avoid always calling `sh -c umask` on startup, instead deferring
the invocation until the first time a working tree file needs to
use the execute bit. This allows servers using bare repos to avoid
a costly fork+exec for a value that is never used.
Store the umask as an int instead of two Boolean. This is slightly
smaller memory (one int vs. two references) and makes it easier for
an application to force setting the umask to a value that overrides
whatever the shell told JGit.
Simplify the code to bail by returning early when canExecute is
false, which is the common case for working tree files.

Applications that use a commit message once and do not
need it again can free the body to save memory. Expose
the disposeBody() methods to support this and use it in
pgm.Log which only visits each commit once.

This was added a very long time ago to support the failed
DHT storage implementation. Since then no storage system
was able to make use of this API, but it pollutes internals
of the walkers.
Kill the API on ObjectReader and drop the invocations from
the walker code.

Previously using an ObjectWalk meant uninteresting commits may keep
their commit message buffers in memory just in case they were found to
be on the boundary and were output as UNINTERESTING for the caller.
This was incorrect inside StartGenerator. ObjectWalk hides these
internal UNINTERESTING cases from its caller unless RevSort.BOUNDARY
was explicitly set, and its false by default. Callers never see one
of these saved uninteresting commits.
Change the test to allow early dispose unless the application has
explicitly asked for RevSort.BOUNDARY. This allows uninteresting
commit buffers to be discarded and garbage collected in ObjectWalks
when the caller will never be given the RevCommit.

Despite being the primary author of RevWalk and ObjectWalk I still
fail to remember to setRetainBody(false) in application code using
an ObjectWalk to examine the graph.
Document the default for RevWalk is setRetainBody(true), where the
application usually wants the commit bodies to display or inspect.
Change the default for ObjectWalk to setRetainBody(false), as nearly
all callers want only the graph shape and do not need the larger text
inside a commit body. This allows some code in JGit to be simplified.

Instead of dumping a full stack trace when a client sends an invalid
commit, record only a short line explaining the attempt:
Cannot receive Invalid commit c0ff33...: invalid author into /tmp/jgit.git
The text alone is sufficient to explain the problem and the stack
trace does not lend any additional useful information. ObjectChecker
is quite clear about its rejection cases.

When DirCacheTree.contains() is called and 'aOff' is greater than 'aLen'
an ArrayIndexOutOfBoundsException was thrown. This fix makes
DirCacheTree.contains() more robust and allows parsing such index files
without throwing AIOOB.
I couldn't create a test case leading to this situation but I have seen
such situations while inspecting Bug: 465393. It seems that such
situations are created on Windows when there are invalid pathes in the
index. There may be a not yet known bug leading to such situations in
combination with invalid pathes.

Since git-core ff5effd (v1.7.12.1) the native wire protocol transmits
the server and client implementation and version strings using
capability "agent=git/1.7.12.1" or similar.
Support this in JGit and hang the implementation data off UploadPack
and ReceivePack. On HTTP transports default to the User-Agent HTTP
header until the client overrides this with the optional capability
string in the first line.
Extract the user agent string into a UserAgent class under transport
where it can be specified to a different value if the application's
build process has broken the Implementation-Version header in the
JGit package.

Add fsck.allowInvalidPersonIdent to accept invalid author/committers
A larger than expected number of real-world repositories found on
the Internet contain invalid author, committer and tagger lines
in their history. Many of these seem to be caused by users misusing
the user.name and user.email fields, e.g.:
[user]
name = Au Thor <author@example.com>
email = author@example.com
that some version of Git (or a reimplementation thereof) copied
directly into the object header. These headers are not valid and
are rejected by a strict fsck, making it impossible to transfer
the repository with JGit/EGit.
Another form is an invalid committer line with double negative for
the time zone, e.g.
committer Au Thor <a@b> 1288373970 --700
The real world is messy. :(
Allow callers and users to weaken the fsck settings to accept these
sorts of breakages if they really want to work on a repo that has
broken history. Most routines will still function fine, however
commit timestamp sorting in RevWalk may become confused by a corrupt
committer line and sort commits out of order. This is mostly fine if
the corrupted chain is shorter than the slop window.

This error happens on nfs file system when you try to read a file that
was deleted or replaced.
When the error happens because the file was deleted, removing it from
the list is the proper way to handle the error, same use case as
FileNotFoundException. When the error happens because the file was
replaced, removing the file from the list will cause the file to be
re-read so it will get the latest version of the file.
