Bug 317411 (Push does not update remote tracking branch) is assigned to
JGit. This test verifies that JGit does the right thing.
Bug: 317411
Change-Id: I8f632e3e6c8a4f16a1170b1dba92e8fd3d6267d0
When parsing a string such as "foo-gbed2" resolve() was assuming the
suffix was from git describe output. This lead to JGit trying to find
the completion for the object abbreviation "bed2", rather than using
the current value of the reference. If there was only one such object
in the repository, JGit might actually use the wrong value here, as
resolve() would return the completion of the abbreviation "bed2"
rather than the current value of the reference "refs/heads/foo-gbed2".
Move the parsing of git describe abbreviations out of the operator
portion of the resolve() method and into the simple portion that is
supposed to handle only object ids or reference names, and only do the
describe parsing after all other approaches have already failed to
provide a resolution.
Add new unit tests to verify the behavior is as expected by users.

Applications may already have a Ref or ObjectId on hand that they want
the remote to be updated to. Instead of converting these into a
String and relying on the parsing rules of resolve(), allow the
application to supply the Ref or ObjectId directly.

If the RevFilter doesn't actually require the commit body,
we shouldn't reparse it if the body was disposed. This happens
often inside of UploadPack during common ancestor negotation, the
RevWalk is reset and re-run over roughly the same commit space,
but the bodies are discarded because the commit message is not
relevant to the process.

Because of change I28ae5713, the commit message lost the "into HEAD" and
caused the MergeCommandTest to fail. This change fixes it.
Bug: 336059

When MergeMessageFormatter was given a symbolic ref HEAD which points to
refs/heads/master (which is the case when merging a branch in EGit), it
would result in a merge message like the following:
Merge branch 'a' into HEAD
But it should print the following (as C Git does):
Merge branch 'a'
The solution is to use the leaf ref when checking for refs/heads/master.

There is no point in pushing all of the files within the edge
commits into the delta search when making a thin pack. This floods
the delta search window with objects that are unlikely to be useful
bases for the objects that will be written out, resulting in lower
data compression and higher transfer sizes.
Instead observe the path of a tree or blob that is being pushed
into the outgoing set, and use that path to locate up to WINDOW
ancestor versions from the edge commits. Push only those objects
into the edgeObjects set, reducing the number of objects seen by the
search window. This allows PackWriter to only look at ancestors
for the modified files, rather than all files in the project.
Limiting the search to WINDOW size makes sense, because more than
WINDOW edge objects will just skip through the window search as
none of them need to be delta compressed.
To further improve compression, sort edge objects into the front
of the window list, rather than randomly throughout. This puts
non-edges later in the window and gives them a better chance at
finding their base, since they search backwards through the window.
These changes make a significant difference in the thin-pack:

This bug was hidden by an incomplete test: the current Rebase
implementation using the "git rebase -i" pattern does not work
correctly if fast-forwarding is involved. The reason for this is that
the log command does not return any commits in this case.
In addition, a check for already merged commits was introduced to
avoid spurious conflicts.

Because this change in the behaviour also broke tests
which expected that a checkout will overwrite untracked

By moving the logic that parses a pack stream from the network (or
a bundle) into a type that can be constructed by an ObjectInserter,
repository implementations have a chance to inject their own logic
for storing object data received into the destination repository.
The API isn't completely generic yet, there are still quite a few
assumptions that the PackParser subclass is storing the data onto
the local filesystem as a single file. But its about the simplest
split of IndexPack I can come up with without completely ripping
the code apart.

Merging Git notes branches has several differences from merging "normal"
branches. Although Git notes are initially stored as one flat tree the
tree may fanout when the number of notes becomes too large for efficient
access. In this case the first two hex digits of the note name will be
used as a subdirectory name and the rest 38 hex digits as the file name
under that directory. Similarly, when number of notes decreases a fanout
tree may collapse back into a flat tree. The Git notes merge algorithm
must take into account possibly different tree structures in different
note branches and must properly match them against each other.
Any conflict on a Git note is, by default, resolved by concatenating
the two conflicting versions of the note. A delete-edit conflict is, by
default, resolved by keeping the edit version.
The note merge logic is pluggable and the caller may provide custom
note merger that will perform different merging strategy.
Additionally, it is possible to have non-note entries inside a notes
tree. The merge algorithm must also take this fact into account and
will try to merge such non-note entries. However, in case of any merge
conflicts the merge operation will fail. Git notes merge algorithm is
currently not trying to do content merge of non-note entries.
Thanks to Shawn Pearce for patiently answering my questions related to
this topic, giving hints and providing code snippets.

Patterns containing only a trailing slash have to be treated
as "global" patterns. For example: "classes/" matches "classes"
as well as "dir/classes" directory.
When an application asks for the names in a section, it may want to
see the existing case that was stored by the user. For example,
Gerrit Code Review wants to store a configuration block like:
[access "refs/heads/master"]
label-Code-Review = group Developers
and although the name label-Code-Review is case-insensitive, it wants
to display the case as it appeared in the configuration file.
When enumerating section names or variable names (both of which are
case-insensitive), Config now keeps track of the string that first
appeared, and presents them in file order, permitting applications to
use this information. To maintain case-insensitive behavior, the
contains() method of the returned Set<String> still performs a
case-insensitive compare.
This is a behavior change if the caller enumerates the returned
Set<String> and copies it to his own Set<String>, and then performs
contains() tests against that, as the strings are now the original
case from the configuration block. But I don't think anyone actually
does this, as the returned sets are immutable and are cached.

Eclipse has some problem re-running single JUnit tests if
the tests are in Junit 3 format, but the JUnit 4 launcher
is used. This was quite unnecessary and the move was not
completed. We still have no JUnit4 test.
This completes the extermination of JUnit3. Most of the
work was global searce/replace using regular expression,
followed by numerous invocarions of quick-fix and organize
imports and verification that we had the same number of
tests before and after.
- Annotations were introduced.
- All references to JUnit3 classes removed
- Half-good replacement for getting the test name. This was
needed to make the TestRngs work. The initialization of
TestRngs was also made lazily since we can not longer find
out the test name in runtime in the @Before methods.
- Renamed test classes to end with Test, with the exception
of TestTranslateBundle, which fails from Maven
- Moved JGitTestUtil to the junit support bundle

If the 'TREE' extension contains an invalid subtree that has
been removed, DirCacheIterator still tried to access it due to
an invalid childCnt field within the parent DirCacheTree object.
This is easy for a user to do, they just need to move all files
out of a subdirectory.
For example, the input for the JUnit test case for this bug was
built using the following C Git sequence:
mkdir -p a/b
touch a/b/c q
git add a/b/c q
git write-tree
git mv a/b/c a/a
After the last step, the subdirectory a/b is empty, as its only
file was moved into the parent directory. Because of the earlier
`git write-tree` operation, there is a 'TREE' extension present, but
the a and a/b subdirectories have been marked invalid by the rename.
When JGit tried to iterate over the a tree, it tried to correct
childCnt to be zero as a/b no longer exists, but it failed to
update childCnt.
