Remove support for the magical "repo-abbrev" comment in .mailmap
files. This was added to .mailmap parsing in [1], as a generalized
feature of the git-shortlog Perl script added earlier in [2].
There was no documentation or tests for this feature, and I don't
think it's used in practice anymore.
What it did was to allow you to specify a single string to be
search-replaced with "/.../" in the .mailmap file. E.g. for
linux.git's current .mailmap:
git archive --remote=git@gitlab.com:linux-kernel/linux.git \
HEAD -- .mailmap | grep -a repo-abbrev
# repo-abbrev: /pub/scm/linux/kernel/git/
Then when running e.g.:
git shortlog --merges --author=Linus -1 v5.10-rc7..v5.10 | grep Merge
We'd emit (the [...] is mine):
Merge tag [...]git://git.kernel.org/.../tip/tip
But will now emit:
Merge tag [...]git.kernel.org/pub/scm/linux/kernel/git/tip/tip
I think at this point this is just a historical artifact we can get
rid of. It was initially meant for Linus's own use when we integrated
the Perl script[2], but since then it seems he's stopped using it.
Digging through Linus's release announcements on the LKML[3] the last
release I can find that made use of this output is Linux 2.6.25-rc6
back in March 2008[4]. Later on Linus started using --no-merges[5],
and nowadays seems to prefer some custom not-quite-shortlog format of
merges from lieutenants[6].
You will still see it on linux.git if you run "git shortlog" manually
yourself with --merges, with this removed you can still get the same
output with:
git log --pretty=fuller v5.10-rc7..v5.10 |
sed 's!/pub/scm/linux/kernel/git/!/.../!g' |
git shortlog
Arguably we should do the same for the search-replacing of "[PATCH]"
at the beginning with "". That seems to be another relic of a bygone
era when linux.git patches would have their E-Mail subject lines
applied as-is by "git am" or whatever. But we documented that feature
in "git-shortlog(1)", and it seems more widely applicable than
something purely kernel-specific.

Add documentation and more tests for case-insensitivity. The existing
test only matched on the E-Mail part, but as shown here we also match
the name with strcasecmp().
This behavior was last discussed on the mailing list in the thread
starting at [1]. It seems we're keeping it like this, so let's
document it.

Change the mailmap documentation added in 0925ce4d49 (Add map_user()
and clear_mailmap() to mailmap, 2009-02-08) to continue discussing the
Jane/Joe example. I think this makes things a lot less confusing as
we're building up more complex examples using one set of data which
covers all the things we'd like to discuss.
Also add tests to assert that what our documentation says is what's
actually happening. This is mostly (or entirely) covered by existing
tests which I'm not deleting, but having these tests for the synopsis
makes it easier to follow-along while reading the tests & docs.

That we silently ignore missing mailmap.file or mailmap.blob values is
intentional. See 938a60d64f (mailmap: clean up read_mailmap error
handling, 2012-12-12). However, nothing tested for this. Let's do that
by checking that stderr is empty in those cases.

Change a test that used a custom fuzzing function since
bfdfa3d414 (t4203 (mailmap): stop hardcoding commit ids and dates,
2010-10-15) to just use the "blame --porcelain" output instead.
We could use the same pattern as 0ba9c9a0fb (t8008: rely on
rev-parse'd HEAD instead of sha1 value, 2017-07-26) does to do this,
but there wouldn't be any point. We're not trying to test "blame"
output here in general, just that "blame" pays attention to the
mailmap.
So it's sufficient to get the blamed line(s) and authors from the
output, which is much easier with the "--porcelain" option.
It would still be possible for there to be a bug in "blame" such that
it uses the mailmap for its "--porcelain" output, but not the regular
output. Let's test for that simply by checking if specifying the
mailmap changes the output.

The --stdin tests setup the "contact" file in the main setup, let's
instead set it up in the test that uses it.
Also refactor the first test so it's obvious that the point of it is
that "check-mailmap" will spew its input as-is when given no
argument. For that one we can just use the "expect" file as-is.
Also add tests for how other "--stdin" cases are handled, e.g. one
where we actually do a mapping.
For the rest of --stdin testing we just assume we're going to get the
same output. We could follow-up and make sure everything's
round-tripped through both --stdin and the file/blob backends, but I
don't think there's much point in that.

Refactor the mailmap tests to:
* Setup "actual" test files in the body of "test_expect_success"
* Don't have X of "test_expect_success X Y" be an unquoted string.
* Not to carry over test config between tests, and instead use
"test_config".
* Replace various "echo" a line-at-a-time patterns with here-docs.
* Change a case of "log.mailmap=False" to use the lower-case
"false". Both work, but this ends up in git-config's boolean
parsing and these atypical values are tested for elsewhere. Let's
use the lower-case to not draw the reader's attention to this
abnormality.
* Remove commentary asserting that things work a given way in favor
of simply testing for it, i.e. in the case of a .mailmap file
outside of the repository.

Create a gitmailmap(5) page similar to how .gitmodules and .gitignore
have their own pages at gitmodules(5) and gitignore(5). Now instead of
"check-mailmap", "blame" and "shortlog" documentation including the
description of the format we link to one canonical place.
This makes things easier for readers, since in our manpage or
web-based[1] output it's not clear that the "MAPPING AUTHORS" sections
aren't subtly different, as opposed to just included.

test_export() has been self-recursive since its inception even though a
simple for-loop would have served just as well to append its arguments
to the `test_export_` variable separated by the pipe character "|".
Recently `test_export_` was changed instead to a space-separated list of
tokens to be exported, an operation which can be accomplished via a
single simple assignment, with no need for looping or recursion.
Therefore, simplify the implementation.
While at it, take advantage of the fact that variable names to be
exported are shell identifiers, thus won't be composed of special
characters or whitespace, thus simple a `$*` can be used rather than
magical `"$@"`.

`git worktree repair` knows how to repair the two-way links between the
repository and a worktree as long as a link in one or the other
direction is sound. For instance, if a linked worktree is moved (without
using `git worktree move`), repair is possible because the worktree
still knows the location of the repository even though the repository no
longer knows where the worktree is. Similarly, if the repository is
moved, repair is possible since the repository still knows the locations
of the worktrees even though the worktrees no longer know where the
repository is.
However, if both the repository and the worktrees are moved, then links
are severed in both directions, and no repair is possible. This is the
case even when the new worktree locations are specified as arguments to
`git worktree repair`. The reason for this limitation is twofold. First,
when `repair` consults the worktree's gitfile (/path/to/worktree/.git)
to determine the corresponding <repo>/worktrees/<id>/gitdir file to fix,
<repo> is the old path to the repository, thus it is unable to fix the
`gitdir` file at its new location since it doesn't know where it is.
Second, when `repair` consults <repo>/worktrees/<id>/gitdir to find the
location of the worktree's gitfile (/path/to/worktree/.git), the path
recorded in `gitdir` is the old location of the worktree's gitfile, thus
it is unable to repair the gitfile since it doesn't know where it is.
Fix these shortcomings by teaching `repair` to attempt to infer the new
location of the <repo>/worktrees/<id>/gitdir file when the location
recorded in the worktree's gitfile has become stale but the file is
otherwise well-formed. The inference is intentionally simple-minded.
For each worktree path specified as an argument, `git worktree repair`
manually reads the ".git" gitfile at that location and, if it is
well-formed, extracts the <id>. It then searches for a corresponding
<id> in <repo>/worktrees/ and, if found, concludes that there is a
reasonable match and updates <repo>/worktrees/<id>/gitdir to point at
the specified worktree path. In order for <repo> to be known, `git
worktree repair` must be run in the main worktree or bare repository.
`git worktree repair` first attempts to repair each incoming
/path/to/worktree/.git gitfile to point at the repository, and then
attempts to repair outgoing <repo>/worktrees/<id>/gitdir files to point
at the worktrees. This sequence was chosen arbitrarily when originally
implemented since the order of fixes is immaterial as long as one side
of the two-way link between the repository and a worktree is sound.
However, for this new repair technique to work, the order must be
reversed. This is because the new inference mechanism, when it is
successful, allows the outgoing <repo>/worktrees/<id>/gitdir file to be
repaired, thus fixing one side of the two-way link. Once that side is
fixed, the other side can be fixed by the existing repair mechanism,
hence the order of repairs is now significant.
Two safeguards are employed to avoid hijacking a worktree from a
different repository if the user accidentally specifies a foreign
worktree as an argument. The first, as described above, is that it
requires an <id> match between the repository and the worktree. That
itself is not foolproof for preventing hijack, so the second safeguard
is that the inference will only kick in if the worktree's
/path/to/worktree/.git gitfile does not point at a repository.

In order to handle recursive merges, after merging merge-bases we need
to clear away most of the data we had built up but some of it needs to
be kept -- in particular the "output" field. Rename the function to
reflect its future change in use.
Further, since "reinitialize" means we'll be reusing the fields
immediately, take advantage of this to only partially clear maps,
leaving the hashtable allocated and pre-sized. (This may be slightly
out-of-order since the speedups aren't realized until there are far
more strmaps in use, but the patch submission process already went out
of order because of various questions and requests for strmap. Anyway,
see commit 6ccdfc2a20 ("strmap: enable faster clearing and reusing of
strmaps", 2020-11-05), for performance details about the use of
strmap_partial_clear().)

In a subsequent commit, we will implement the traditional recursiveness
that gave merge-recursive its name, namely merging non-unique
merge-bases to come up with a single virtual merge base. Copy a few
helper functions from merge-recursive.c that we will use in the
implementation.

When a user does not tell "git pull" to use rebase or merge, the
command gives a loud message telling a user to choose between
rebase or merge but creates a merge anyway, forcing users who would
want to rebase to redo the operation. Fix an early part of this
problem by tightening the condition to give the message---there is
no reason to stop or force the user to choose between rebase or
merge if the history fast-forwards.
* fc/pull-merge-rebase:
pull: display default warning only when non-ff
pull: correct condition to trigger non-ff advice
pull: get rid of unnecessary global variable
pull: give the advice for choosing rebase/merge much later
pull: refactor fast-forward check

There's no need to display the annoying warning on every pull... only
the ones that are not fast-forward.
The current warning tests still pass, but not because of the arguments
or the configuration, but because they are all fast-forward.
We need to test non-fast-forward situations now.

Refactor the advise() call that teaches users how they can choose
between merge and rebase into a helper function. This revealed that
the caller's logic needs to be further clarified to allow future
actions (like "erroring out" instead of the current "go ahead and
merge anyway") that should happen whether the advice message is
squelched out.

Eventually we want to be omit the advice when we can fast-forward
in which case there is no reason to require the user to choose
between rebase or merge.
In order to do so, we need to delay giving the advice up to the
point where we can check if we can fast-forward or not.
Additionally, config_get_rebase() was probably never its true home.

We would like to be able to make this check before the decision to
rebase is made in a future step. Besides, using a separate helper
makes the code easier to follow.

The focus here is on adding a path_msg() which will queue up
warning/conflict/notice messages about the merge for later processing,
storing these in a pathname -> strbuf map. It might seem like a big
change, but it really just is:
* declaration of necessary map with some comments
* initialization and recording of data
* a bunch of code to iterate over the map at print/free time
* at least one caller in order to avoid an error about having an
unused function (which we provide in the form of implementing
modify/delete conflict handling).
At this stage, it is probably not clear why I am opting for delayed
output processing. There are multiple reasons:
1. Merges are supposed to abort if they would overwrite dirty changes
in the working tree. We cannot correctly determine whether changes
would be overwritten until both rename detection has occurred and
full processing of entries with the renames has finalized.
Warning/conflict/notice messages come up at intermediate codepaths
along the way, so unless we want spurious conflict/warning messages
being printed when the merge will be aborted anyway, we need to
save these messages and only print them when relevant.
2. There can be multiple messages for a single path, and we want all
messages for a give path to appear together instead of having them
grouped by conflict/warning type. This was a problem already with
merge-recursive.c but became even more important due to the
splitting apart of conflict types as discussed in the commit
message for 1f3c9ba707 ("t6425: be more flexible with rename/delete
conflict messages", 2020-08-10)
3. Some callers might want to avoid showing the output in certain
cases, such as if the end result is a clean merge. Rebases have
typically done this.
4. Some callers might not want the output to go to stdout or even
stderr, but might want to do something else with it entirely.
For example, a --remerge-diff option to `git show` or `git log
-p` that remerges on the fly and diffs merge commits against the
remerged version would benefit from stdout/stderr not being
written to in the standard form.

This simplistic and weird-looking patch is here to facilitate future
patch submissions. Adding this stub allows rename detection code to
reference it in one patch series, while a separate patch series can
define the implementation, and then both series can merge cleanly and
work nicely together at that point.

Commit b658536f59 ("merge-ort: add some high-level algorithm structure",
2020-10-27) added high-level structure of the ort merge algorithm. As
we have added more and more functions, that high-level structure has
been slightly obscured. Since functions are still grouped according to
this high-level structure, add comments denoting sections where all the
functions are specifically tied to a piece of the high-level structure.
This function groupings include a few sub-divisions of the original
high-level structure, including some sub-divisions that are yet to be
submitted. Each has (or will have) several functions all serving as
helpers to one or two main functions for each section.
As an added bonus, the comments will serve to provide a small textual
separation between nearby sections and allow the next three patch series
to be submitted independently and merge cleanly.

Include blob.h for definition of blob_type, and commit-reach.h for
declarations of get_merge_bases() and in_merge_bases(). While none of
these are used yet, we want to avoid cross-dependencies in the next
three series of patches for merge-ort and merge them at the end; adding
these "#include"s now avoids textual conflicts.
