If we hit a corrupt object or invalid pack remove the pack from the pack
list. Other IOException could be transient hence we should not remove
the pack from the list to avoid the problem reported on the Gerrit list
[1]. It looks like in the reported case the pack was removed from the
pack list causing MissingObjectExceptions which disappear when the
server is restarted.

The path matcher should not fail if the rule ends with trailing slash,
target pattern does not ends with the slash and the "assumeDirectory"
flag is set.
E.g. */bin/ should also match a/bin if this pattern is threated as
directory by WorkingTreeIterator (FileMode.TREE).
The old code/tests have never tested directory rules with patterns
*without* trailing slashes but with the "assumeDirectory" flag set.
Unfortunately this is exactly what WorkingTreeIterator does... The tests
are changed to test *both* cases now (with trailing slash and without)
if the target pattern has trailing slash (represents directory).

Windows creates shortnames for all non-8.3 files (see [1]). Hence we
need to disallow all names which could potentially be a shortname for
".git". Example: in an empty directory create a folder "GIT~1". Now you
can't create another folder ".git".
The path "GIT~1" may map to ".git" on Windows. A potential victim to
such an attack first has to initialize a git repository in order to
receive any git commits. Hence the .git folder created by init will get
the shortname "GIT~1". ".git" will only get a different shortname if the
user has created a file "GIT~1" before initialization of the git
repository.

When updating a submodule (e.g. during recursive clone) the repository
for the submodule should be located at <gitdir>/modules/<submodule-path>
whereas the working tree of the submodule should be located at
<working-tree>/<submodule-path> (<gitdir> and <working-tree> are
associated to the containing repository). Since CloneCommand has learned
about specifying a separate gitdir this is easy to implement in
SubmoduleUpdateCommand.

Native git's "init" command allows to specify the location of the .git

setup repositories with a non-standard layout. E.g. .git folder under
/repos/a.git and the worktree under /home/git/a. Both directories
contain pointers to the other side: /repos/a.git/config contains
core.worktree=/home/git/a . And /home/git/a/.git is a file containing
"gitdir: /repos/a.git". This commit adds that option to InitCommand.

If the text extent height of a to be rendered plot line is odd, then the
SWTPlotRenderer cannot calculate the correct Y position for drawing the
label and draws the label with a 1 pixel offset. SWT text drawing uses
the baseline as Y coordinate. Due to the given centerline API in the
AbstractPlotRenderer the overall calculation of the baseline for SWT is
effectively (height / 2) * 2, thereby rounding all odd heights downward
to the next even number.
This change pushes the division by 2 from the caller into the
implementations of drawText. A corresponding change will be pushed in

JGit's ObjectDirectory implements the optimization that it remembers the
pack folders (.git/objects/pack) lastModified timestamp and doesn't
check for new packfiles in this folder if the lastModified attribute has
not changed.
In environments using NFS this can cause trouble. If multiple JGit
instances from multiple machines work on the same repository and one
instance creates a new ref and a new packfile (e.g. by doing a fetch)
then the other machines may detect the new ref but can't resolve the
referenced object because it doesn't detect that pack folder has a new
packfile. That's because NFS may cache file/folder metadata for quite a
long time and the pack folders modification time is not updated although
a new packfile is there and could be read.
The new config parameter core.trustfolderstat controls this behaviour.
The default is true and jgits behaviours is unchanged. But if this
parameter is set to false then jgit doesn't trust the pack directories
lastmodified anymore. Instead it will always iterate through the content
of that folder to detect new packfiles.

Before a rebase happens the RebaseCommand checks that the working tree
is clean. We don't want to start a rebase on a dirty working tree. If
the working tree is dirty a rebase should not be allowed. But
RebaseCommand should ignore modifications done to submodules. E.g. if a
submodules HEAD points to <x> but the root repository has in index that
the submodule should point to <y> then this should not prohibit a
rebase. Also native git allows a rebase in this case. Since jgit's
StatusCommand has learned to ignore submodule changes this is now used
by the RebaseCommand to determine the repository state correctly.

The current IgnoreRule/FileNameMatcher implementation scales not well
with huge repositories - it is both slow and memory expensive while
parsing glob expressions (bug 440732). Addtitionally, the "double star"
pattern (/**/) is not understood by the old parser (bug 416348).
The proposed implementation is a complete clean room rewrite of the
gitignore parser, aiming to add missing double star pattern support and
improve the performance and memory consumption.
The glob expressions from .gitignore rules are converted to Java regular
expressions (java.util.regex.Pattern). java.util.regex.Pattern code can
evaluate expression from gitignore rules considerable faster (and with
less memory consumption) as the old FileNameMatcher implementation.

Applications sometimes use a RevFlag instead of a Set<RevObject>
to track boolean state bits about objects being processed. However
this requires careful use of the resetRetain() methods to avoid an
accidental clearing of the RevFlag bits, effectively clearing the
Set<RevObject> the application wanted to track.
Simplify that use case by offering retainOnReset, a collection of
flags that are never cleared by the RevWalk.

When writing new packs it should be allowed to specify objects as "have"
(objects which should not be included in the pack) which do not exist in
the local repository.
This works with the traditional PackWriter, but when PackWriter was
working on a repository with bitmap indexes and used
PackWriterBitmapWalker then this feature was broken. Non-existing "have"
objects lead to MissingObjectExceptions. That broke push and Gerrit
replication. When the replication target had branches unknown to the
replication source then the source repository wanted to build pack files
where "have" included branch-tips which were unknown in the source
repository.

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

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 :

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

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.

As described in native gits file "git-read-tree.txt" git has in a
special mode when doing the "initial" checkout. "Initial" means that the
index is empty before the checkout. This was not handled correctly in
JGit and is fixed in this commit. Also see

Setting branch.<name>.rebase or pull.rebase to 'preserve' will preserve
merges during rebase. Also, pull.rebase is now consulted if there is no
branch-specific configuration.

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
the parent comparison code, but hidden behind a protected constructor.

Originally, blame's walk to find a scapegoat to blame for a file
walking backward from a commit used the test
treeWalk.getFileMode(0).getObjectType() != OBJ_BLOB
to throw out gitlink (submodule) entries. Later, 52500d3264 (blame:
Micro optimize blob lookup in tree, 2014-04-17) changed that test to
(treeWalk.getRawMode(0) & TYPE_FILE) != TYPE_FILE
These checks are not the same, though: the older test accepts files
and symlinks, while the newer one accepts files, symlinks, and gitlink
(submodule) entries. This is particularly broken in the submodule
case --- trying to parse the referred-to commit as a blob produces
caught an exception: GET /gerrit/+blame/master/plugins/reviewnotes HTTP/1.1
org.eclipse.jgit.errors.MissingObjectException: Missing blob 61702414c046dd6b811c9137b765f9db422f83db
Stick to just (possibly executable) files instead. Symlinks are not
line-oriented data so blame on a symlink is not likely to be useful.
A quick grep for '& TYPE_' doesn't find any other instances of this
bug.

TranslationBundle#load() used to load resource bundles through
ResourceBundle#getBundle() without explicitly specifying a class loader.
In this case, the class laoder of the calling class (TranslationBundle
here) is used. This approach fails in runtime environments like OSGi
where there are multiple class loaders.
This change enables loading resource bundles in multi class loaders
environments. The fix is to pass the class loader of the
TranslationBundle-derived class to ResourceBundle#getBundle().

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.
