JGit should offer the possibility to do a garbage collection in
"aggressive" mode. In this mode garbage collection more aggressively
optimize the repository at the expense of taking much more time.
Technically a aggressive mode garbage collection differs from a
non-aggressive one by:
- not reusing packed objects found in old packs. Recompress every object
- the configuration pack.window is set to 250 (the default is 10)
- the configuration pack.depths is set to 250 (the default is 50)
The associated classes in org.eclipse.jgit.api and the command line
command in org.eclipse.jgit.pgm expose this new option.
The configuration parameters gc.aggressiveDepth and gc.aggressiveWindow
have been introduced to configure this feature.

uninteresting
Using the ObjectWalk and marking a commit as uninteresting didn't mark
its root tree as uninteresting. This caused the "missing tree ..."
error in Gerrit under special circumstances. For example, if the
patch-set 2 changes only the commit message then the patch-set 1
and patch-set 2 share the same root-tree:
ps1 -> o o <- ps2
\ /
o root-tree
The transported pack will contain the ps2 commit but not the root-tree
object.
When using the BaseReceivePack.setCheckReferencedObjectsAreReachable
JGit will check the reachability of all referenced objects not provided
in the transported pack. Since the ps1 was advertised it will properly
be marked as uninteresting. However, the root-tree was reachable because
the ObjectWalk.markUninteresting missed to mark it as uninteresting.
JGit was then rejecting the pack with the "missing tree ..." exception.

The native implementation of inflate() can set finished to return
true at the same time as it copies the last bytes into the buffer.
Check for finished on each iteration, terminating as soon as libz
knows the stream was completely inflated.
If not finished, it is likely input is required before the next
native call could do any useful work. Most invocations are passing
in a buffer large enough to store the entire result. A partial return
from inflate() will need more input before it can continue. Checking
right away that needsInput() is true saves a native call to determine
no bytes can be inflated without more input.
This should fix a rare infinite loop condition inside of inflation
when an object ends exactly at the end of a block boundary, and
the next block contains only the 20 byte trailing SHA-1.
When the stream is finished each new attempt to inflate() returns
n == 0, as no additional bytes were output. The needsInput() test
tries to add the length of the footer block to itself, but then loops
back around an reloads the same block as the block is smaller than
a full block size. A zero length input is set to the inflater,
which triggers needsInput() condition again.

This allows the RecursiveMerger to iteratively create new merge bases
without necessarily flushing packs to storage in the DFS case;
flushing only need happen at the end of the whole merge process.
Since Merger's walk now depends on its inserter, we need to construct
an inserter at Merger construction time. This should not be a
significant increase in overhead since unused inserters don't use any
resources (beyond a reference to the Repository).
We also must release and recreate the walk whenever setObjectInserter
is called, which can break usages where setObjectInserter is called in
the middle of stateful operations on the walk. No usages of this
method within JGit currently do this; the inserter is only ever set
before any stateful walk operations happen.

In the DFS implementation, flushing an inserter writes a new pack to
the storage system and is potentially very slow, but was the only way
to ensure previously-inserted objects were available. For some tasks,
like performing a series of three-way merges, the total size of all
inserted objects may be small enough to avoid flushing the in-memory
buffered data.
DfsOutputStream already provides a read method to read back from the
not-yet-flushed data, so use this to provide an ObjectReader in the
DFS case.
In the file-backed case, objects are written out loosely on the fly,
so the implementation can just return the existing WindowCursor.

Previously when RecursiveMerger was trying to create a single virtual
common base for the merge it was failing when this lead to content-merge
conflicts. This is different from what native git is doing. When native
git's recursive merge algorithm creates a new common base it will merge
the multiple parents and simply take the merge result (potentially
including conflict markers) as common base. See my discussion with Shawn
here: http://www.spinics.net/lists/git/msg234959.html :
> - How should workingtree, index (stage1,2,3) look like if during

Its done entirely in memory and never touches the working tree or
index. When a conflict exists in the X1-X2 merge the conflict is
preserved into the new virtual base.
There is still the possibility that the merge of parents lead to
conflicts. File/Folder conclicts, conflicts on filemodes. This commit
only fixes the situation for conflicts when merging content.

When RecursiveMerger tried to determine a common base tree it was
recursively tried to merge multiple common bases. But these intermediate
merges which have just been done to determine a single common base for
the final merge already filled some important fields (toBeCheckedOut,
toBeDeleted, ...). These side effects of the intermediate merges led to
wrong results of the final merge. One symptom was that after a recursive
merge which should be succesful you could still see leftover files in
the worktree: files which existed in the (virtual) common base but which
don't exist anymore in the branches to be merged.
The solution is easy: Clear the appropriate fields after common base
determination and start the final merge with a clean state.

With --preserve-merges C Git re-does merges using the rewritten merge
parents, discarding the old merge commit. For the common use-case of
pull with rebase this is unfortunate, as it loses the merge conflict
resolution (and other fixes in the merge), which may have taken quite
some time to get right in the first place.
To overcome this we use a two-fold approach:
If any of the (non-first) merge parents of a merge were rewritten, we
also redo the merge, to include the (potential) new changes in those
commits.
If only the first parent was rewritten, i.e. we are merging a branch
that is otherwise unaffected by the rebase, we instead cherry-pick the
merge commit at hand. This is done with the --mainline 1 and --no-commit
options to apply the changes introduced by the merge. Then we set up an
appropriate MERGE_HEAD and commit the result, thus effectively forging a
merge.
Apart from the approach taken to rebase merge commits, this
implementation closely follows C Git. As a result, both Git
implementations can continue rebases of each other.
Preserving merges works for both interactive and non-interactive rebase,
but as in C Git it is easy do get undesired outcomes with interactive
rebase.
CommitCommand supports committing merges during rebase now.

The current behavior of passing a TreeFilter to RevWalk has limited
usefulness, since the RevFilter derived from the TreeFilter is always
ANDed together with any other RevFilters. It is also tied fairly
tightly to the parent rewriting mechanism.
Make TreeRevFilter a generic RevFilter that matches modified paths
against any TreeFilter. This allows for more complex logic like
(modified this path OR authored by this person).
Leave the rewrite flag logic in this class, since it's closely tied to

These checks are not the same, though: the older test accepts files

0b5441a8 introduced an enum for authentication types and changed the
case of digest and basic authentication type names to all uppercase.
This broke digest authentication at least when using Gerrit as the git
server.
According to RFC2617 [1] "Basic" and "Digest" is the literal to be used
in authentication headers and not "BASIC" [1] and "DIGEST" [2].
According to RFC4559 "Negotiate" [3] is used for SPNEGO based
authentication.

If a client passes a multiline message as argument to ReflogWriter.log()
the Reflog gets corrupted and cannot be parsed. ReflogWriter.log() is
invoked implicitly from various commands such as StashCreate, Rebase and
many more. However the message is not always filtered for line feeds.
Such an example is the StashCreateOperation of EGit which passes
unchecked user input as commit message. If a multiline comment is pasted
to the stash create dialog, the reflog gets corrupted.
ReflogWriter now replaces line endings in log message with spaces.

The aim of this change is to place all commits of a branch on the same
lane and commits of other (side) branches on different lanes.
The algorithm treats first parents of a commit specially by placing them
on the same lane as the commit itself. When a commit is the first parent
of multiple children it could be placed on any of these children's
lanes. In this case it is placed on the longest child lane, as this is
usually the lane of the branch the commit actually was made on.
Other (non-first) parents are placed on new lanes. This creates a layout
that should make it easier to see branches and merges and follow linear
branch histories.
This differs from the previous approach, which sometimes plotted the
commits of a side branch on the same lane as the base branch commits and
further commits on the base branch appeared on a different lane.
This made the base branch appear as if it was the side branch and
the side branch appears to be the base branch.
In addition to lane assignment, also the plotting code changed to start
drawing a branch lane from the commit where it forks out. Previously it
started only when the first commit on the branch appeared.
Active lanes are continued with every commit that is processed.
Previously lanes were only continued when the next commit on the lane
was encountered. This could produce (temporarily) dangling commits if
the next commit on the lane was not processed yet.

Child commits always have a lane assigned when their parents are
processed, so this code is no longer necessary.
Children only assign themselves to parents in
PlotCommitList.setupChildren(), which is called from enter(), when the
child is processed. If the child leaves enter() it should always have a
lane assigned. As a result of this, when processing a parent, all its
known children already have lanes assigned. If the underlying RevWalk
emits a parent before one of its children (which it should not do), the
parent does not know of the child emitted later, because setupChildren()
has not been called for the child yet. So even in this case, no child
without a lane is encountered when processing a (parent) commit.

Sun HttpURLConnection is able to handle authentication like SPNEGO without
caller intervention. However, there are some restrictions:
- do not need user direct input (user,password for example)
- it doesn't work when request body is chunked/streamed (because it cannot be
replayed)
Unfortunately there is no real way to leverage HttpURLConnection authentication
work as the authentication header is stripped off the request before returning
to the caller. There's also no way to explicitly disable authentication in
HttpURLConnection (SPNEGO auth will always be attempted if a valid token can be
created by GSSAPI).
This is an issue for jgit since it is expected that the first request will be
used to detect authentication method, and reuse for the subsequent requests.
This patch modifies TransportHTTP to detect authentication done in the background
by HttpURLConnection and sets the jgit authentication method accordingly so it will
always work for future requests (assuming that the authentication method used by
HttpURLConnection is also supported by jgit).

On Sun JDK, Sun GSSManagerImpl can be configured directly for SPNEGO auth
(without setting any system property). For a better experience, the class
availability is detected by reflection and used instead.
Detection is only done once, and fallbacks to org.ietf.jgss.GSSManager.

This partially reverts 6de12836d7.
Performing a TreeWalk over 2 trees to identify and skip unmodified
subtrees to pass all blame onto an ancestor appears to be a micro
optimization that works for a very limited number of files. In the
general case the 2 tree walk is slowing down blame more than it helps
to speed it up.
I keep coming up with files in multiple repositories where 6de128 is
making things worse, not better, and only one example where it
actually improved performance, render_view_impl.cc in chromium
as described in the commit message.

Do not rewrite parents in RevWalkTextBuiltins
RevWalk: Allow disabling parent rewriting
RevWalkTextBuiltin: Add -n to limit number of commits returned
Previously, setting any TreeFilter on a RevWalk triggered parent
rewriting, which in the current StartGenerator implementation ends up
buffering the entire commit history in memory. Aside from causing poor
performance on large histories, this does not match the default
behavior of `git rev-list`, which does not rewrite parent SHAs unless
asked to via --parents/--children.

behavior. Continue rewriting parents by default to maintain backwards

When blaming a merge commit with "Ignore whitespace changes" enabled,
don't discard blame candidates for other parents when we encounter a
parent that only has whitespace changes compared to the merge result.
The algorithm early prepares parents for blaming, removing the
appropriate blame regions from the list of regions still to blame. Only
at the end, the prepared blame candidates are submitted for blaming.
When looking at a non-first parent which only differs in whitespace to
the merge result, it submitted that parent, but only to blame it for the
(usually few) lines not already prepared to blame on other parents. Due
to an early return the blame candidates for the previous parents were
forgotten, leaving many lines unannotated.

With this commit running blame on render_view_impl.cc[1] saves
about 644 ms over prior versions, reducing the time about 4.5%.
Large projects often contain strands of commits where no changes
are made to a particular subtree. Blame used to dive recursively
into these subtrees to look for the blob and check if its SHA-1
was changed. In chromium/src[1] only 20% of the commits modify
the content/renderer subtree relevant for the file.
The recursivePath is necessary to check for '/' and remember
if common subtree elimination should be attempted. When a file
lives within a subtree the extra cost to check for unmodified
subtrees saves time. However for files in the root tree the
extra work incurred by TreeWalk is not worthwhile and would
significantly increase overall running time.
Now typical running times from an otherwise idle desktop:

Avoid converting the raw mode to FileMode. This is an expensive

Instead test the bit mask directly, which is at least a few
instructions shorter.
The TreeWalk is already recursive and will auto-dive into any
subtrees found. isSubtree check is unnecessary, as is the loop,
as only one result will ever be returned by next().

Problem:
The BlameGenerator used the RevFlag SEEN to mark commits it had
already looked at (but not necessarily processed), to prevent
processing a commit multiple times. If a commit is a conflicting
merge that contains lines of the merge base, that have been deleted
in its first parent, either these lines or the lines untouched
since the merge base would not be blamed properly.
This happens for example if a file is modified on a main branch in an
earlier commit M and on a side branch in a later commit S. For this
example, M deletes some lines relative to the common base commit B,
and S modifies a subset of these lines, leaving some other of these
lines untouched.
Then side is merged into main, creating a conflict for these
lines. The merge resolution shall carry over some unmodified lines
from B that would otherwise be deleted by M. The route to blame
these lines is via S to B. They can't be blamed via M, as they
don't exist there anymore.
Q
|\
| \
| S

B
Blaming the merged file first blames via S, because that is the
most recent commit. Doing so, it also looks at B to blame the
unmodified lines of B carried over by S into the merge result. In the
course of this, B is submitted for later processing and marked SEEN.
Later M is blamed. It notices that its parent commit B has been
SEEN and aborts processing for M. B is blamed after that, but only
for the lines that survived via S.
As a result, only the lines contributed by S or by B via S are
blamed. All the other lines that were unchanges by both M and S,
which should have been blamed to B via M, are not blamed.
Solution:
Don't abort processing when encountering a SEEN commit. Rather add the
new region list of lines to be blamed to those of the already SEEN and
enqueued commit's region list. This way when the B commit of the
above example is processed, it will blame both the lines of M and S,
yielding a complete blame result.
