There was a bug regarding how JGit handled untracked files when applying
a stash. Problem was that untracked files are applied by doing a merge
of HEAD and untrackedFiles commit with a merge base of the stashed HEAD.
That's wrong because the untrackedFiles commit has no parent and
contains only the untracked files. Using stashed HEAD as merge base
leads to unneccessary conflicts on files not event included in the
untrackedFiles commit.
Imagine this graph directly before you want to apply a stash which was
based on 0. You want to apply the stash on current HEAD commit 5.
5 (HEAD,master)
/
0---+
\ \
1---3 (WIP on master)
/
2 (untracked files on master)
Imagine for a specific (tracked) file f
- commit 0 contains X
- HEAD contains Y
- commit 2 (the untracked files) does not contain file f
A merge of 2 and 5 with a merge base of 0 leads to a conflict. The 5
commit wants to modify the file and the 2 commit wants to delete the
file -> conflict.
If no merge base is set then the semantic is correct.
Thanks to Bow for finding this bug and providing the test case.

There are references which are returned by
RefDatabase.getAdditionalRefs() which are allowed to point to
non-existing objects. These refs should not save objects from being
garbage collected. Examples for these references are ORIG_HEAD,
MERGE_HEAD, FETCH_HEAD and CHERRY_PICK_HEAD. Native git will not take
these references into account when doing a gc and therefore these
references may point to non-existing objects after a gc. Teach JGit's
GC to behave the same: ignore additional refs if they don't start with
"refs/". Examples for refs returned by getAdditionalRefs() which do
start with "refs/" are the bootstrap refs when using reftree's (see
commit 115f1ad3974d1162b33d1c8eff466019d1f249f3). See also

When performing a "reset --hard" a checkout is done. The pathes are
checked for potential checkout conflicts. But in the end for all
remaining conflicts these files are simply deleted from the working
tree. That's not the right strategy to handle checkout conflicts during
"reset --hard". Instead for every conflict we should simply checkout the
merge commit's content.
This is different from native gits behavior which reports errors when
during a "checkout --hard" a file shows up where a folder was expected.
"warning: unable to unlink d/c.txt: Not a directory"
Why it is like that in native git was asked in
http://permalink.gmane.org/gmane.comp.version-control.git/279482. Unless
it is explained why native git why this error is reported JGit should
overwrite the files.

Before this change, jgit used to read packed-refs before scanning
loose refs. That was not a problem if gc didn't run concurrently. When
gc did run concurrently with such refs reading, that order sometimes
broke the latter. This lead to reading an older version of a ref's
tip, which meant "losing" the real tip or commit. The specific
read-Vs-gc concurrency scenario which broke reading that way follows:
1. let ref R be in packed-refs and R' be in loose
2. jgit starts reading packed-refs
3. gc also starts its business around that very time
4. jgit still has the time to read R from packed-refs
5. as gc is not done yet updating packed-refs with R'
6. jgit then starts scanning loose refs (or is about to)
7. gc quickly ends up being done moving loose R' to packed-refs
8. so gc (quickly) removes loose refs
9. -while jgit is scanning loose refs, now gone
10. so jgit assumes no loose to consider => packed-refs winning
11. so jgit wrongfully returns R (from 4.) as the tip, instead of R'.
This fix switches the order so loose refs are scanned (secured) before
taking the time to read packed-refs. This way, knowledge of the
likelier tip is guaranteed for ref reading to return the true tip
- despite concurrent gc. If there is no loose ref to scan, jgit reads
packed-refs and lands on R' (or S), which it then returns, as
expected. The gerrit issue [1] should be solved by this fix.

Neon Eclipse platform requires BREE 8 so we have to use Java 8 at least
for the JGit packaging build (for the compiler settings we still stick
to source and target 1.7 since we want to still support Java 7)
otherwise unpacking platform pack200 archives will fail since they are
built using Java 8 and hence cannot be unpacked using Java 7's
unpack200.
Update org.junit from 4.11 to 4.11 and org.apache.ant from from 1.9.2 to

The special characters <> and '\n' interfere with parsing of
identities. C git strips these special characters, so we should too.
Rather than allocating extra strings by calling String#trim(), add a
few lines to our sanitization method to perform the same trimming as
described in String's Javadoc.

This might be somewhat surprising behavior to users who might
naturally assume the following invariant:
ident.equals(parseIdent(ident.toExternalString()))
This invariant does not hold since whitespace is only trimmed during
serialization. We don't want to mess with the strings during
initialization, as this is called during the highly-optimized commit
parsing codepath.

We've found in Gerrit Code Review that it is common to pass around
both an ObjectReader (or more commonly a RevWalk wrapping one) and an
ObjectInserter. These code paths often assume that the ObjectReader
can read back any objects created by the ObjectInserter without
flushing. However, we previously had no way to enforce that constraint
programmatically, leading to hard-to-spot problems.
Provide a solution by exposing the ObjectInserter that created an
ObjectReader, when known. Callers can either continue passing both
objects and check:
reader.getCreatedFromInserter() == inserter
or they can just pass around ObjectReader and extract the inserter
when it's needed (checking that it's not null at usage time).

Repurpose RefDatabase#performsAtomicTransactions() slightly, to
indicate that the backend _supports_ atomic transactions, rather than
the current definition, which is that the backend always _uses_ atomic
transactions regardless of whether or not the caller actually wants
them. Allow BatchRefUpdate callers to turn off atomic transactions by
calling setAtomic(false). Defaulting to true means this is backwards
compatible.

PackWriter.writeObject() can get into an infinite loop when corrupt
packs are present. When it finds a pack file with an object that can be
reused it calls DfsPackFile.copyAsIs(). If that method sees an invalid
CRC, it adds the object to the DfsPackFile's corrupt object list and
throws a CorruptObjectException, which it later catches as an
IOException and wraps in a
StoredObjectRepresentationNotAvailableException.
PackWriter.writeObjectImpl() catches that SORNAE and retries the
operation by calling DfsReader.selectObjectRepresentation(). But
currently that method returns the same object which was just seen to
be corrupt.
Change DfsPackFile.isCorrupt() from private to package private, and use
that method in DfsReader.selectObjectRepresentation() to filter out
corrupt objects.
The stack traces that show the problem are:
