The commit-graph file is now part of the "files that the runtime

Calculating the sum of two array indexes to find the midpoint between
them can overflow, i.e. code like this is unsafe for big arrays:
mid = (first + last) >> 1;
Make sure the intermediate value stays within the boundaries instead,
like this:
mid = first + ((last - first) >> 1);
The loop condition of the binary search makes sure that 'last' is
always greater than 'first', so this is safe as long as 'first' is
not negative. And that can be verified easily using the pre-context
of each change, except for name-hash.c, so add an assertion to that
effect there.
The unsafe calculations were found with:
git grep '(.*+.*) *>> *1'
This is a continuation of 19716b21a4 (cleanup: fix possible overflow
errors in binary search, 2017-10-08).

The close_all_packs() method is now responsible for more than just pack-files.
It also closes the commit-graph and the multi-pack-index. Rename the function
to be more descriptive of its larger role. The name also fits because the
input parameter is a raw_object_store.

The write_commit_graph() and write_commit_graph_reachable() methods
currently take two boolean parameters: 'append' and 'report_progress'.
As we update these methods, adding more parameters this way becomes
cluttered and hard to maintain.
Collapse these parameters into a 'flags' parameter, and adjust the
callers to provide flags as necessary.

The write_commit_graph() method uses die() to report failure and
exit when confronted with an unexpected condition. This use of
die() in a library function is incorrect and is now replaced by
error() statements and an int return type. Return zero on success
and a negative value on failure.
Now that we use 'goto cleanup' to jump to the terminal condition
on an error, we have new paths that could lead to uninitialized
values. New initializers are added to correct for this.
The builtins 'commit-graph', 'gc', and 'commit' call these methods,
so update them to check the return value. Test that 'git commit-graph
write' returns a proper error code when hitting a failure condition
in write_commit_graph().

As many CI/CD tools don't allow to control command line options when
executing `git tag` command, a default value in the configuration file
will allow to enforce tag signing if required.
The new config-file option tag.gpgSign is added to define default behavior
of tag signings. To override default behavior the command line option -s,
--sign and --no-sign can be used:
$ git tag -m "commit message"
will generate a GPG signed tag if tag.gpgSign option is true, while
$ git tag --no-sign -m "commit message"
will skip the signing step.

Commit e198b3a740 changed the behavior of fetch with regards to tags.
Before, null oids where not ignored, now they are, regardless of whether
the refs have been explicitly cleared or not.
e198b3a740 (fetch: replace string-list used as a look-up table with a hashmap)
When using a transport helper the oids can certainly be null. So now
tags are ignored and fetching them is impossible.
This patch fixes that by having a specific flag that is set only when we
explicitly want to ignore the refs, restoring the original behavior.

The availability of these pattern selections is not obvious from
the man pages, as per mail thread <87lfz3vcbt.fsf@evledraar.gmail.com>.
Provide examples.
Re-order the `git branch` synopsis to emphasise the `--list <pattern>`
pairing. Also expand and reposition the `all/remotes` options.
Split the over-long description into three parts so that the <pattern>
description can be seen.
Clarify that the `all/remotes` options require the --list if patterns
are to be used.
Add examples of listing remote tracking branches that match a pattern,
including `git for-each-ref` which has more options.
Improve the -a/-r warning message. The message confused this author
as the combined -a and -r options had not been given, though a pattern
had. Specifically guide the user that maybe they needed the --list
option to enable a remote branch pattern selection.

Convert option_commit to tristate, representing the states of
'default/untouched', 'enabled-by-cli', 'disabled-by-cli'. With this in
place, check whether option_commit was enabled by cli when squashing a
merge. If so, error out, as this is not supported.
Previously, when --squash was supplied, 'option_commit' was silently
dropped. This could have been surprising to a user who tried to override
the no-commit behavior of squash using --commit explicitly.
Add a note to the --squash option for git-merge to clarify the
incompatibility, and add a test case to t7600-merge.sh

In --interactive mode, "git am --resolved" will try to generate a patch
based on what is in the index, so that it can prompt "apply this
patch?". To do so it needs the tree of HEAD, which it tries to get with
get_oid_tree(). However, this doesn't yield a tree object; the "tree"
part just means "if you must disambiguate short oids, then prefer trees"
(and we do not need to disambiguate at all, since we are feeding a ref).
Instead, we must parse the oid as a commit (which should always be true
in a non-corrupt repository), and access its tree pointer manually.
This has been broken since the conversion to C in 7ff2683253
(builtin-am: implement -i/--interactive, 2015-08-04), but there was no
test coverage because of interactive-mode's insistence on having a tty.
That was lifted in the previous commit, so we can now add a test for
this case.
Note that before this patch, the test would result in a BUG() which
comes from 3506dc9445 (has_uncommitted_changes(): fall back to empty
tree, 2018-07-11). But before that, we'd have simply segfaulted (and in
fact this is the exact type of case the BUG() added there was trying to
catch!).

We have required that the stdin of "am --interactive" be a tty since
a1451104ac (git-am: interactive should fail gracefully., 2005-10-12).
However, this isn't strictly necessary, and makes the tool harder to
test (and is unlike all of our other --interactive commands).
The goal of that commit was to make sure that somebody does not do:
git am --interactive <mbox
and cause us to read commands from the mbox. But we can simply check
up front for this case and complain before entering the interactive
loop.
Technically this disallows:
git am --interactive </dev/null
where our lack of patches means we would never prompt for anything, and
so the old code would not notice our lack of tty (and now we'd die
early). But since such a command is totally pointless, it's no loss.

In the conversion of git-am from shell script to C, we switched to using
git_prompt(). Unlike the original shell command "read reply", this
doesn't read from stdin at all, but rather from /dev/tty.
In most cases this distinction wouldn't matter. We require (as the shell
script did) that stdin is a tty, so they would generally be the same
thing. But one important exception is our test suite: even with
test_terminal, we cannot test "am --interactive" because it insists on
reading from /dev/tty, not the pseudo-tty we've set up in the test
script.
Fixing this clears the way to adding tests in a future patch.

We'll never see a NULL returned from git_prompt(); if it can't produce
any input for us (e.g., because the terminal got EOF) then it will just
die().
So there's no need for us to handle NULL here. And even if there was, it
doesn't make sense to continue; on a true terminal hangup we'd just loop
infinitely trying to get input that will never come.

When using `git clone --recurse-submodules` there was previously no way to
pass a `--remote` switch to the implicit `git submodule update` command for
any use case where you want the submodules to be checked out on their
remote-tracking branch rather than with the SHA-1 recorded in the superproject.
This patch rectifies this situation. It actually passes `--no-fetch` to
`git submodule update` as well on the grounds they the submodule has only just
been cloned, so fetching from the remote again only serves to slow things down.

This allows to cancel the current merge without resetting worktree/index,
which is what --abort is for. Like other --quit(s), this is often used
when you forgot that you're in the middle of a merge and already
switched away, doing different things. By the time you've realized, you
can't even continue the merge anymore.
This also makes all in-progress commands, am, merge, rebase, revert and
cherry-pick, take all three --abort, --continue and --quit (bisect has a
different UI).
