A bitmap index contains bitmaps for a set of commits in a pack file.
Creating a bitmap for every commit is too expensive, so heuristics
select the most "important" commits. The most recent commits are the
most valuable. To clone a repository only those for the branch tips are
needed. When fetching, only commits since the last fetch are needed.
The commit selection heuristics generally work, but for some
repositories the number of selected commits is prohibitively high. One
example is the MSM 3.10 Linux kernel. With over 1 million commits on
2820 branches, the current heuristics resulted in +36k selected commits.
Each uncompressed bitmap for that repository is ~413k, making it
difficult to complete a GC operation in available memory.
The benefit of creating bitmaps over the entire history of a repository
like the MSM 3.10 Linux kernel isn't clear. For that repository, most
history for the last year appears to be in the last 100k commits.
Limiting bitmap commit selection to just those commits reduces the count
of selected commits from ~36k to ~10.5k. Dropping bitmaps for older
commits does not affect object counting times for clones or for fetches
on clients that are reasonably up-to-date.
This patch defines a new "bitmapCommitRange" PackConfig parameter to
limit the commit selection process when building bitmaps. The range
starts with the most recent commit and walks backwards. A range of 10k
considers only the 10000 most recent commits. A range of zero creates
bitmaps only for branch tips. A range of -1 (the default) does not limit
the range--all commits in the pack are used in the commit selection
process.

On a server also running Gerrit that is using RepoCommand to
convert from an XML manifest to a git submodule superproject
periodically, it would be handy to be able to use Gerrit's
submodule subscription feature[1] to update the superproject
automatically between RepoCommand runs as changes are merged
in each subprojects.
This requires setting the 'branch' field for each submodule
so that Gerrit knows what branch to watch. Add an option to
do that.
Setting the branch field also is useful for plain Git users,
since it allows them to use "git submodule update --remote" to
manually update all submodules between RepoCommand runs.

This patch makes JGit parsing of ignore rules containing unmatched '['
bracket compatible to the Git CLI.
Since '[' starts character group, Git tries to parse the ignore rule as
a shell glob pattern and if the character group is not closed, the glob
pattern is invalid and so the ignore rule never matches anything.

An attempt to re-implement not well documented Git CLI behavior for
patterns with backslashes.
It looks like Git silently ignores all \ characters in ignore rules, if
they are NOT covered by 3 cases described in [1]:
{quote}
1) ... Put a backslash ("\") in front of the first hash for patterns
that begin with a hash.
...
2) Trailing spaces are ignored unless they are quoted with backslash
("\").
...
3) Put a backslash ("\") in front of the first "!" for patterns that
begin with a literal "!", for example, "\!important!.txt".
{quote}
Undocumented also is the fact that backslash itself can be escaped by
backslash.
So \h\e\l\l\o\.t\x\t rule matches hello.txt and a\\\\b a\b in Git CLI.
Additionally, the glob parser [2] knows special meaning of backslash:
{quote}
One can remove the special meaning of '?', '*' and '[' by preceding
them by a backslash, or, in case this is part of a shell command
line, enclosing them in quotes. Between brackets these characters
stand for themselves. Thus, "[[?*\]" matches the four characters
'[', '?', '*' and '\'.

The current way of processing submodules results in no hunk header and
includes the contents of the hunk as part of the headers. To fix this, we
can't just have our writeGitLinkDiffText output the hunk header. We have
to change the flow so that the raw text gets parsed as a diff. The easiest
way to do this is to fake the RawText in the FormatResult when we have a
GITLINK.
It should be noted that it seems possible for there to be a difference
between a GITLINK and a non-GITLINK, but I don't think this can happen in
practice, so I don't think we need to worry too much about it.
This patch also fixes up the test for GitLink headers, as the test was
for the old behavior. My setup has 3 other failing tests which may or
may not be the result of environmental changes. However, the same tests
fail without this commit, so I do not believe they are related.

Adding a command to the batch for this case is harmless as it will

Consider a BatchRefUpdate produced by Gerrit Code Review, where the
original command pushed over the wire might refer to
"refs/for/master", but that command is ignored and replaced with some
additional commands like creating "refs/changes/34/1234/1". We do not
want to store the cert in "refs/for/master@{cert}", since that may
lead someone looking to the ref to the incorrect conclusion that that
ref exists.
Add a separate put method that takes a collection of commands, and
only stores certs on those refs that have a matching command in the
cert.

Inspired by a proposal from gitolite[1], where we store a file in
a tree for each ref name, and the contents of the file is the latest
push cert to affect that ref.
The main modification from that proposal (other than lacking the
out-of-git batching) is to append "@{cert}" to filenames, which allows
storing certificates for both refs/foo and refs/foo/bar. Those
refnames cannot coexist at the same time in a repository, but we do
not want to discard the push certificate responsible for deleting the
ref, which we would have to do if refs/foo in the push cert tree
changed from a tree to a blob.
The "@{cert}" syntax is at least somewhat consistent with
gitrevisions(7) wherein @{...} describe operators on ref names.
As we cannot (currently) atomically update the push cert ref with the
refs that were updated, this operation is inherently racy. Kick the can
down the road by pushing this burden on callers.

We intend to store received push certificates somewhere, like a
particular ref in the repository in question. For reading data back

framing) in a streaming fashion.
Change-Id: I70de313b1ae463407b69505caee63e8f4e057ed4
Discussion on the git mailing list has concluded[1] that the intended
behavior for all (non-sideband) portions of the receive-pack protocol
is for trailing LFs in pkt-lines to be optional. Go back to using
PacketLineIn#readString() everywhere.
For push certificates specifically, we agreed that the payload signed
by the client is always concatenated with LFs even though the client
MAY omit LFs when framing the certificate for the wire. This is still
reflected in the implementation of PushCertificate#toText().
