This test case assumed file system timestamp resolution of 1 second. On
filesystems with a finer resolution this test fails since the index
entry is only smudged if the file index entry's lastModified and the
lastModified of the git index itself are within the same filesystem
timer tick. Fix this by ensuring that these timestamps are identical
which should work for any filesystem timer resolution.

Archives created by the ArchiveCommand didn't produce deterministic
archive hashes. For RevCommits RevWalk.parseTree returns the root tree
instead of the RevCommit hence retrieving the commit's timestamp didn't
work. Instead use RevWalk.parseAny and extract the tree manually.
Archive entries store timestamps with 1 second resolution hence we need
to wait longer when creating the same archive twice and compare archive
hashes. Otherwise hash comparison in tests wouldn't fail without this
patch.

An inner class should be static unless it references members of its

uses more memory and does not make the intent of the class clear.

(cherry picked from commit ee40efcea4)
Error Prone reports the warning on several classes:
[NonOverridingEquals] equals method doesn't override Object.equals;
if this is a type-specific helper for a method that does override
Object.equals, either inline it into the callers or rename it to
avoid ambiguity.
See https://errorprone.info/bugpattern/NonOverridingEquals
Most of these are in the public API, so we can't rename or inline them
without breaking the API. FileSnapshot is not part of the public API,
but clients may be using it anyway, so we also shouldn't change that.
Suppress all the warnings instead. Having the check at severity ERROR
will at least make sure we don't introduce any new occurrences.

A merging pull on an unborn branch was already supported. But a
rebasing pull failed. If the user has pull.rebase = true in his
user config, the pull would try to rebase. Rebasing needs a parent
commit, though. Native git handles this case:
git init
git remote add origin <URI>
git pull --rebase origin master
Check up front in PullCommand for the unborn head and just do a
checkout in this case. MergeCommand already has similar code.

Commit messages of length 1 were not read. 'lineEnd' is the offset
of the last character in the line before the terminating LF or CR-LF,
and 'nextSpace' is actually the offset of the character _after_ the
next space. With a one-character commit message, nextSpace == lineEnd.
The code also assumes the commit message to be optional, but actually
failed in that case because it read beyond the line ending. Fix that,
too.
Add a test case for reading a todo file.
