Jonathan Tan 32798dcfdb Always send refs' objects despite "filter" in pack
In a0c9016abd ("upload-pack: send refs' objects despite "filter"",
2018-07-09), Git updated the "filter" option in the fetch-pack
upload-pack protocol to not filter objects explicitly specified in
"want" lines, even if they match the criterion of the filter. Update
JGit to match that behavior.

Thomas Wolf a9b54b026d ResolveMerger: don't try needlessly to delete directories
Don't try to delete folders if the merger chooses THEIRS, but all of
BASE, OURS, and THEIRS contain the folder.

Add a test for rebase with auto-stash and subdirectories that
verifies this case. The needless directory deletion and reporting
such directories in getModifiedFiles() was the root cause of bug
536880.

Note even with this fix, bug 536880 will not be fixed in all cases
yet. There may still be cases where the set of modified files ends
up containing directories. This will be dealt with in EGit where
this set is used. (See https://git.eclipse.org/r/#/c/126242/ .)

Christian Halstrick 6db9371250 Ensure RacyGitTests don't raise false negatives
RacyGitTests depend on filesystem timer resolution. We wait for a file
system timer tick, remember that time as t1, modify a file and assume
that this file has a lastmodified of t1.

If this assumption is not fulfilled then ignore the test result.

Masaya Suzuki 579bff6653 Add API to specify the submodule name
Currently SubmoduleAddCommand always uses the path as submodule name.
This patch lets the caller specify a submodule name.

SubmoduleUpdateCommand still does not make use of the submodule name
(see bug 535027) but Git does.  To avoid triggering CVE-2018-11235,
do some validation on the name to avoid '..' path components.

Minh Thai 263a8c1c06 Make Reftable seek* and has* method names more consistent
Make the method names more consistent and their semantics simpler:
hasRef and seekRef to look up a single exact reference by name and
hasRefsByPrefix and seekRefsByPrefix to look up multiple references by
name prefix.

In particular, splitting hasRef into two separate methods for its
different uses makes DfsReftableDatabase.isNameConflicting easier to
follow.

Minh Thai e04d96e3fa Seek references by prefix in reftable
Reftable implementation of RefDatabase.getRefsByPrefix() should be
more performant, as references are filtered directly by prefix;
instead of fetching the whole subtree then filter by prefix.

Terry Parker 00e51e35ee Return parsed objects from TestRepository.commit/tree/blob()
It is convenient for TestRepository to return fully parsed
objects from its commit()/tree()/blob() methods, so that test
code doesn't have to remember to parse them before making
assertions about them.

Update TestRepostiory to return fully parsed objects.
Adjust the tests that are affected by this change in behavior.

Terry Parker 115a740e2f Correctly handle initialization of shallow commits
In a new RevWalk, if the first object parsed is one of the
shallow commits, the following happens:
1) RevCommit.parseCanonical() is called on a new "r1" RevCommit.
2) RevCommit.parseCanonical() immediately calls
   RevWalk.initializeShallowCommits().
3) RevWalk.initializeShallowCommits() calls lookupCommit(id),
   creating and adding a new "r2" version of this same object and
   marking its parents empty.
4) RevCommit.parseCanonical() initializes the "r1" RevCommit's
   fields, including the parents.
5) RevCommit.parseCanonical()'s caller uses the "r1" commit that
   has parents, losing the fact that it is a shallow commit.

This change passes the current RevCommit as an argument to
RevWalk.initializeShallowCommits() so that method can set its
parents empty rather than creating the duplicate "r2" commit.

JGit now considers lightweight tags only if the --tags option is set
i.e. `git.describe().setAllTags(true)` has to be set, else the default
is now as in c git:

Only annotated tags are evaluated unless you pass true
equivalent to --tags (or --all) by the option setAllTags.

Hint: This (still) doesn't address any difference between c-git
`--all` and `!--all --tags` behavior;
perhaps this might be a follow up request

Dave Borowitz 96512f5d3b Move DfsPackDescription comparators to common location
There are several ways of comparing DfsPackDescriptions for different
purposes, such as object lookup search order and reftable ordering. Some
of these are later compounded into comparators on other objects, so they
appear in the code as Comparator<DfsReftable>, for example.

Put all the DfsPackDescription comparators in static methods on
DfsPackDescription itself. Stop implementing Comparable, to avoid giving
the impression that there is always one true and correct way of sorting
packs.

Rather than requiring callers to do their own computations based on the

Comparator<PackSource> instance, and explicitly discourage usage of
default Enum comparison.

Construct the default comparator using a builder pattern based on
defining equivalence classes. This gives us the same behavior as the old
category field in PackSource, with an abstraction that does not leak the
implementation detail of comparing rank numbers.

Thomas Wolf d7deda98d0 Skip ignored directories in FileTreeIterator
Make FileTreeIterator not enter ignored directories by default. We
only need to enter ignored directories if we do some operation against
git, and there is at least one tracked file underneath an ignored
directory.

Walking ignored directories should be avoided as much as possible as
it is a potential performance bottleneck. Some projects have a lot of
files or very deep hierarchies in ignored directories; walking those
may be costly (especially so on Windows). See for instance also bug
500106.

Provide a FileTreeIterator.setWalkIgnoredDirectories() operation to
force the iterator to iterate also through otherwise ignored
directories. Useful for tests (IgnoreNodeTest, CGitIgnoreTest), or
to implement things like "git ls-files --ignored".

Add tests in DirCacheCheckoutTest, and amend IndexDiffTest to test a
little bit more.

Han-Wen Nienhuys f3ec7cf3f0 Remove further unnecessary 'final' keywords
Remove it from

 * package private functions.

 * try blocks

 * for loops

this was done with the following python script:

$ cat f.py
import sys
import re
import os

def replaceFinal(m):
  return m.group(1) + "(" +  m.group(2).replace('final ', '') + ")"

methodDecl = re.compile(r"^([\t ]*[a-zA-Z_ ]+)\(([^)]*)\)")

def subst(fn):
  input = open(fn)
  os.rename(fn, fn + "~")

  dest = open(fn, 'w')
  for l in input:
    l = methodDecl.sub(replaceFinal, l)
    dest.write(l)
  dest.close()


for root, dirs, files in os.walk(".", topdown=False):
  for f in files:
    if not f.endswith('.java'):
      continue

    full = os.path.join(root, f)
    print full
    subst(full)
