When safeForMacOS is enabled the checker verifies a name does not
match against another name in the same tree after normalization to
NFC. The check was incorrect and failed when the first name was put
in, rejecting simple trees containing only one file like "F".
Add a test for this simple tree to verify it is accepted.
Fix the test for NFC normalization to actually normalize
and have a collision.

When working on a non-bare repository with a detached HEAD jgit's GC was
packing the ref named "HEAD" into the packed-refs file and deleted the
loose ref (the file .git/HEAD!). This made the repo unusable for native
git. This is fixed by telling jgit to only pack refs starting from
"refs/"

Previously, calling addAnnotatedTags() did not modify any state when
there were no annotated tags in the repository. This caused the code
to assume no addFoo() methods had been called, and fell back to the
default of adding refs/*. Instead, use null to indicate neither
addRefs() nor addAnnotatedTags() was called.
Add a test for this behavior.

Under certain circumstances isMergedInto() returned
false even though base is reachable from the tip.
This will hinder pushes and receives by falsely
detecting "non fast forward" merges.
o---o---o---o---o
/ \
/ o---o---A---o---M
/ /
---2---1-
if M (tip) was compared to 1 (base), the method
isMergedInto() could still return false, since
two mergeBases will be detected and the return
statement will only look at one of them:
return next() == base;
In most cases this would pass, but if "A" is
a commit with an old timestamp, the Generator
would walk down to "2" before completing the
walk pass "A" and first finding the other
merge base "1". In this case, the first call to
next() returns 2, which compared to base evaluates
as false.
This is fixed by iterating merge bases and
returning true if base is found among them.

JGit wants to control retries during ssh authentication. But JSch by
default already retries 6 times. Hence disable retries in JSch. Without

Copying flags through a graph with deep side branches can cause
StackOverflowError. The recursive step to visit the 2nd parent of
a merge commit can overflow the stack if these are themselves very
deep histories with many branches.
Rewrite the loop to iterate up to 500 recursive steps deep before
unwinding the stack and running the remaining parts of the graph
using a dynamically allocated FIFORevQueue.
This approach still allows simple graphs that mostly merge short
lived topic branches into master to copy flags with no dynamic
memory allocation, relying only on temporary stack extensions.
Larger more complex graphs only pay the allocation penalities
if copying has to extend outwards "very far" in the graph, which
is unlikely for many coloring based algorithms.

Verifying 100 new objects are fully connected to the existing DAG

fully connected when pushing it to a new repository can take 30-60

knows the server is still working.

Repositories that are frequently checked out on Windows platforms
may need to ensure trees do not contain strange names that cause
problems on those systems. Follow the MSDN guidelines and refuse
to accept a tree containing a special character, or names that end
with " " (space) or "." (dot).
Since Windows filesystems are usually case insensitive, also reject
mixed case versions of the reserved ".git" name.

The leading '0' is a broken mode that although incorrect in the
Git canonical tree format was created by a couple of libraries

these modes stuck in their ancient history and cannot easily

ObjectChecker to ignore them.

Catching Exception and rethrowing as Error when the Java7 factory was
not available threw an unexpected error to the caller, but then
confused things by still setting the factory to the default Java

Do not throw to the caller. Instead always default to the Java5
factory if the Java7 one is not loading.

Blaming with core.autocrlf set to 'true' - even for freshly checked out
files - showed all lines as being locally modified. For autocrlf = true
the line breaks of the local file will be converted to LF for blaming.
This results in useful diffs and therefor in the desired blame
annotations.
For autocrlf = input no conversion takes place to cope with CRLF line
breaks in the repository, in addition to the usual LF. For autocrlf =
true CRLF line breaks in the repo can't be supported without additional
effort. In that case the whole local file will be blamed as being
locally modified.

During a checkout we want to prevent to overwrite unsaved local file
content. Jgit was therefore checking whether the file to overwrite is
dirty or missing and would raise a conflict if this was the case. That
was wrong. It should only check if the file is dirty. It's ok to
"overwrite" a missing/non-existing file.
