When submitting a revised version of a patch or series, it can be
helpful (to reviewers) to include a summary of changes since the
previous attempt in the form of an interdiff, typically in the cover
letter. However, it is occasionally useful, despite making for a noisy
read, to insert an interdiff into the commentary section of the lone
patch of a 1-patch series.
Therefore, extend "git format-patch --interdiff=<prev>" to insert an
interdiff into the commentary section of a lone patch rather than
requiring a cover letter. The interdiff is indented to avoid confusing
git-am and human readers into considering it part of the patch proper.
Implementation note: Generating an interdiff for insertion into the
commentary section of a patch which itself is currently being generated
requires invoking the diffing machinery recursively. However, the
machinery does not (presently) support this since it uses global state.
Consequently, we need to take care to stash away the state of the
in-progress operation while generating the interdiff, and restore it
after.

The --interdiff option introduces the embedded interdiff generically as
"Interdiff:", however, we can do better when --reroll-count is specified
by emitting "Interdiff against v{n}:" instead.

When submitting a revised version of a patch series, it can be helpful
(to reviewers) to include a summary of changes since the previous
attempt in the form of an interdiff, however, doing so involves manually
copy/pasting the diff into the cover letter.
Add an --interdiff option to automate this process. The argument to
--interdiff specifies the tip of the previous attempt against which to
generate the interdiff. For example:
git format-patch --cover-letter --interdiff=v1 -3 v2
The previous attempt and the patch series being formatted must share a
common base.

git-rebase.sh wrote strategy options to .git/rebase/merge/strategy_opts
in the following format:
'--ours' '--renormalize'
Note the double spaces.
git-rebase--interactive uses sequencer.c to parse that file, and
sequencer.c used split_cmdline() to get the individual strategy options.
After splitting, sequencer.c prefixed each "option" with a double dash,
so, concatenating all its options would result in:
-- --ours -- --renormalize
So, when it ended up calling try_merge_strategy(), that in turn would run
git merge-$strategy -- --ours -- --renormalize $merge_base -- $head $remote
instead of the expected/desired
git merge-$strategy --ours --renormalize $merge_base -- $head $remote
Remove the extra spaces so that when it goes through split_cmdline() we end
up with the desired command line.

"git diff" compares the index and the working tree. For paths
added with intent-to-add bit, the command shows the full contents
of them as added, but the paths themselves were not marked as new

In preparation for deprecating "-l", let's make sure we're
using the recommended option ourselves.
This patch just mechanically converts "branch -l" to "branch
--create-reflog". Note that with the exception of the
actual "--create-reflog" test, we could actually remove "-l"
entirely from most of these callers. That's because these
days core.logallrefupdates defaults to true in a non-bare
repository.
I've left them in place, though, since they serve to
document the expectation of the test, even if they are
technically noops.

This test checks that the "-l" option creates a reflog. But
in fact we'd create one even without it, since the default
in a non-bare repository is to do so. Let's unset the config
so we can be sure our "-l" option is kicking in.
Note that we can't do this with test_config, since that
would leave the variable unset after our test finishes,
confusing downstream tests (the helper is not not smart
enough to restore the previous value, and just always runs
test_unconfig).

Teach 'git-grep(1)' a new option, '--column', to show the column
number of the first match on a non-context line. This makes it possible
to teach 'contrib/git-jump/git-jump' how to seek to the first matching
position of a grep match in your editor, and allows similar additional
scripting capabilities.
For example:
$ git grep -n --column foo | head -n3
.clang-format:51:14:# myFunction(foo, bar, baz);
.clang-format:64:7:# int foo();
.clang-format:75:8:# void foo()

When users specify the commit range with 'Z..C' pattern for format-patch, all
the parents of Z (including Z) would be marked as UNINTERESTING which would
prevent revision walk in prepare_bases from getting the prerequisite commits,
thus `git format-patch --base <base_commit_sha> Z..C` won't be able to generate
the list of prerequisite patch ids. Clear UNINTERESTING flag with
clear_object_flags solves this issue.

Ever since commit 18633e1a22 ("rebase -i: use the rebase--helper builtin",
2017-02-09), when a commit marked as 'reword' in an interactive rebase
has conflicts and fails to apply, when the rebase is resumed that commit
will be squashed into its parent with its commit message taken.
The issue can be understood better by looking at commit 56dc3ab04b
("sequencer (rebase -i): implement the 'edit' command", 2017-01-02), which
introduced error_with_patch() for the edit command. For the edit command,
it needs to stop the rebase whether or not the patch applies cleanly. If
the patch does apply cleanly, then when it resumes it knows it needs to
amend all changes into the previous commit. If it does not apply cleanly,
then the changes should not be amended. Thus, it passes !res (success of
applying the 'edit' commit) to error_with_patch() for the to_amend flag.
The problematic line of code actually came from commit 04efc8b57c
("sequencer (rebase -i): implement the 'reword' command", 2017-01-02).
Note that to get to this point in the code:
* !!res (i.e. patch application failed)
* item->command < TODO_SQUASH
* item->command != TODO_EDIT
* !is_fixup(item->command) [i.e. not squash or fixup]
So that means this can only be a failed patch application that is either a
pick, revert, or reword. We only need to amend HEAD when rewording the
root commit or a commit that has been fast-forwarded, for any of the other
cases we want a new commit, so we should not set the to_amend flag.

The on-disk ewah format tells us how big the ewah data is,
and we blindly read that much from the buffer without
considering whether the mmap'd data is long enough, which
can lead to out-of-bound reads.
Let's make sure we have data available before reading it,
both for the ewah header/footer as well as for the bit data
itself. In particular:
- keep our ptr/len pair in sync as we move through the
buffer, and check it before each read
- check the size for integer overflow (this should be
impossible on 64-bit, as the size is given as a 32-bit
count of 8-byte words, but is possible on a 32-bit
system)
- return the number of bytes read as an ssize_t instead of
an int, again to prevent integer overflow
- compute the return value using a pointer difference;
this should yield the same result as the existing code,
but makes it more obvious that we got our computations
right
The included test is far from comprehensive, as it just
picks a static point at which to truncate the generated
bitmap. But in practice this will hit in the middle of an
ewah and make sure we're at least exercising this code.

Support for the --set-upstream option was removed in 52668846ea
(builtin/branch: stop supporting the "--set-upstream" option,
2017-08-17). The change did not completely remove the command
due to an issue noted in the commit's log message.
So, a test was added to ensure that a command which uses the
'--set-upstream' option fails instead of silently acting as an alias
for the '--set-upstream-to' option due to option parsing features.
To avoid confusion, clarify that the option is disabled intentionally
in the corresponding test description.
The test is expected to be around as long as we intentionally fail
on seeing the '--set-upstream' option which in turn we expect to
do for a period of time after which we can be sure that existing
users of '--set-upstream' are aware that the option is no
longer supported.

Some of our tests try to make sure Git behaves sensibly in a
read-only directory, by dropping 'w' permission bit before doing a
test and then restoring it after it is done. The latter is needed
for the test framework to clean after itself without leaving a
leftover directory that cannot be removed.
Ancient parts of tests however arrange the above with
chmod a-w . &&
... do the test ...
status=$?
chmod 775 .
(exit $status)
which obviously would not work if the test somehow dies before it
has the chance to do "chmod 775". Rewrite them by following a more
robust pattern recently written tests use, which is
test_when_finished "chmod 775 ." &&
chmod a-w . &&
... do the test ...

When a submodules work tree is removed, we should unset its core.worktree
setting as the worktree is no longer present. This is not just in line
with the conceptual view of submodules, but it fixes an inconvenience
for looking at submodules that are not checked out:
git clone --recurse-submodules git://github.com/git/git && cd git &&
git checkout --recurse-submodules v2.13.0
git -C .git/modules/sha1collisiondetection log
fatal: cannot chdir to '../../../sha1collisiondetection': \
No such file or directory
With this patch applied, the final call to git log works instead of dying
in its setup, as the checkout will unset the core.worktree setting such
that following log will be run in a bare repository.
This patch covers all commands that are in the unpack machinery, i.e.
checkout, read-tree, reset. A follow up patch will address
"git submodule deinit", which will also make use of the new function
submodule_unset_core_worktree(), which is why we expose it in this patch.
