We presently use the ".txt" extension for our AsciiDoc files. While not
wrong, most editors do not associate this extension with AsciiDoc,
meaning that contributors don't get automatic editor functionality that
could be useful, such as syntax highlighting and prose linting.
It is much more common to use the ".adoc" extension for AsciiDoc files,
since this helps editors automatically detect files and also allows
various forges to provide rich (HTML-like) rendering. Let's do that
here, renaming all of the files and updating the includes where
relevant. Adjust the various build scripts and makefiles to use the new
extension as well.
Note that this should not result in any user-visible changes to the
documentation.

The documentation for git-diff has been updated to follow the new
documentation guidelines. The following changes have been applied to
the series of patches:
- switching the synopsis to a synopsis block which will automatically
format placeholders in italics and keywords in monospace
- use _<placeholder>_ instead of <placeholder> in the description
- use `backticks for keywords and more complex option
descriptions`. The new rendering engine will apply synopsis rules to
these spans.
- prevent git-diff from self-referencing itself via gitlink macro when
the generated link would point to the same page.

A handful of manual pages called AUTO_MERGE a "special ref", but
there is nothing special about it. It merely is yet another
pseudoref.

Since 5291828df8 (merge-ort: write $GIT_DIR/AUTO_MERGE whenever we hit a
conflict, 2021-03-20), when using the 'ort' merge strategy, the special
ref AUTO_MERGE is written when a merge operation results in conflicts.
This ref points to a tree recording the conflicted state of the working
tree and is very useful during conflict resolution. However, this ref is
not documented.
Add some documentation for AUTO_MERGE in git-diff(1), git-merge(1),
gitrevisions(7) and in the user manual.
In git-diff(1), mention it at the end of the description section, when
we mention that the command also accepts trees instead of commits, and
also add an invocation to the "Various ways to check your working tree"
example.
In git-merge(1), add a step to the list of things that happen "when it
is not obvious how to reconcile the changes", under the "True merge"
section. Also mention AUTO_MERGE in the "How to resolve conflicts"
section, when mentioning 'git diff'.
In gitrevisions(7), add a mention of AUTO_MERGE along with the other
special refs.
In the user manual, add a paragraph describing AUTO_MERGE to the
"Getting conflict-resolution help during a merge" section, and include
an example of a 'git diff AUTO_MERGE' invocation for the example
conflict used in that section. Note that for uniformity we do not use
backticks around AUTO_MERGE here since the rest of the document does not
typeset special refs differently.

"git diff rev^!" did not show combined diff to go to the rev from
its parents.
* rs/diff-caret-bang-with-parents:
diff: support ^! for merges
revisions.txt: unspecify order of resolved parts of ^!
revision: use strtol_i() for exclude_parent
|
|
revision.c::handle_revision_arg_1() resolves <rev>^! by first adding the
negated parents and then <rev> itself. builtin_diff_combined() expects
the first tree to be the merge and the remaining ones to be the parents,
though. This mismatch results in bogus diff output.
Remember the first tree that doesn't belong to a parent and use it
instead of blindly picking the first one. This makes "git diff <rev>^!"
consistent with "git show <rev>^!".

Add a CONFIGURATION section to the documentation of various built-ins,
for those cases where the relevant config/NAME.txt doesn't map only to
one git-NAME.txt. In particular:
* config/blame.txt: used by git-{blame,annotate}.txt. Since the
git-annotate(1) documentation refers to git-blame(1) don't add a
"CONFIGURATION" section to git-annotate(1), only to git-blame(1).
* config/checkout.txt: maps to both git-checkout.txt and
git-switch.txt (but nothing else).
* config/init.txt: should be included in git-init(1) and
git-clone(1).
* config/column.txt: We should ideally mention the relevant subset of
this in git-{branch,clean,status,tag}.txt, but let's punt on it for
now. We will when we eventually split these sort of files into
e.g. config/column.txt and
config/column/{branch,clean,status,tag}.txt, with the former
including the latter set.
Things that are being left out, and why:
* config/{remote,remotes,credential}.txt: Configuration that affects
how we talk to remote repositories is harder to untangle. We'll need
to include some of this in git-{fetch,remote,push,ls-remote}.txt
etc., but some of those only use a small subset of these
options. Let's leave this for now.

When `git diff --merge-base` was introduced at around Git 2.30, the
documentation included a few errors.
In the example given for `git diff --cached --merge-base`, the
`--cached` flag was omitted for the `--merge-base` example. Add the
missing flag.
In the `git diff <commit>` case, we failed to mention that
`--merge-base` is an available option. Give the usage of `--merge-base`
as an option there.
Finally, there are two errors in the usage of `git diff`. Firstly, we do
not mention `--merge-base` in the `git diff --cached` case. Mention it
so that it's consistent with the documentation. Secondly, we put the
`[--merge-base]` in between `<commit>` and `[<commit>...]`. Move the
`[--merge-base]` so that it's beside `[<options>]` which is a more
logical grouping.

The previous commit introduced ---merge-base a way to take the diff
between the working tree or index and the merge base between an arbitrary
commit and HEAD. It makes sense to extend this option to support the
case where two commits are given too and behave in a manner identical to
`git diff A...B`.
Introduce the --merge-base flag as an alternative to triple-dot
notation. Thus, we would be able to write the above as
`git diff --merge-base A B`.

There is currently no easy way to take the diff between the working tree
or index and the merge base between an arbitrary commit and HEAD. Even
diff's `...` notation doesn't allow this because it only works between
commits. However, the ability to do this would be desirable to a user
who would like to see all the changes they've made on a branch plus
uncommitted changes without taking into account changes made in the
upstream branch.
Teach diff-index and diff (with one commit) the --merge-base option
which allows a user to use the merge base of a commit and HEAD as the
"before" side.

The description of `git diff` goes through several different invocations
(numbering added by me):
1. git diff [<options>] [--] [<path>...]
2. git diff [<options>] --no-index [--] <path> <path>
3. git diff [<options>] --cached [<commit>] [--] [<path>...]
4. git diff [<options>] <commit> [--] [<path>...]
5. git diff [<options>] <commit> <commit> [--] [<path>...]
6. git diff [<options>] <commit>..<commit> [--] [<path>...]
7. git diff [<options>] <commit> <commit>... <commit> [--] [<path>...]
8. git diff [<options>] <commit>...<commit> [--] [<path>...]
It then goes on to say that "all of the <commit> in the above
description, except in the last two forms that use '..' notations, can
be any <tree>". The "last two" actually refers to 6 and 8. This got out
of sync in commit b7e10b2ca2 ("Documentation: usage for diff combined
commits", 2020-06-12) which added item 7 to the mix.
As a further complication, after b7e10b2ca2 we also have some potential
confusion around "the '..' notation". The "..[.]" in items 6 and 8 are
part of the rev notation, whereas the "..." in item 7 is manpage
language for "one or more".
Move item 6 down, i.e., to between 7 and 8, to restore the ordering.
Because 6 refers to 5 ("synonymous to the previous form") we need to
tweak the language a bit.
An added bonus of this commit is that we're trying to steer users away
from `git diff <commit>..<commit>` and moving it further down probably
doesn't hurt.

Commit b7e10b2ca2 ("Documentation: usage for diff combined commits",
2020-06-12) modified the synopsis by adding an optional "[<commit>...]"
to
'git diff' [<options>] <commit> <commit> [--] [<path>...]
to effectively add
'git diff' [<options>] <commit> <commit>... <commit> [--] [<path>...]
as another valid invocation. Which makes sense.
Further down, in the description, it left the existing entry for
'git diff' [<options>] <commit> <commit> [--] [<path>...]
intact and added a new entry on
'git diff' [<options>] <commit> [<commit>...] <commit> [--] [<path>...]
where it says that "[t]his form is to view the results of a merge
commit" and details how "the first listed commit must be the merge
itself". But one possible instantiation of this form is `git diff
<commit> <commit>` for which the added text doesn't really apply.
Remove the brackets so that we lose this overlap between the two
descriptions. We can still use the more compact representation in the
synopsis.

Within diff_no_index(), we have the following:
revs->diffopt.flags.exit_with_status = 1;
...
/*
* The return code for --no-index imitates diff(1):
* 0 = no changes, 1 = changes, else error
*/
return diff_result_code(&revs->diffopt, 0);
Which means when `git diff` is run in `--no-index` mode, `--exit-code`
is implied. However, the documentation for this is missing in
git-diff.txt.
Add a note about how `--exit-code` is implied in the `--no-index`
documentation to cover this documentation blindspot.

The point of these sections is generally to:
1. Give credit where it is due.
2. Give the reader an idea of where to ask questions or
file bug reports.
But they don't do a good job of either case. For (1), they
are out of date and incomplete. A much more accurate answer
can be gotten through shortlog or blame. For (2), the
correct contact point is generally git@vger, and even if you
wanted to cc the contact point, the out-of-date and
incomplete fields mean you're likely sending to somebody
useless.
So let's drop the fields entirely from all manpages except
git(1) itself. We already point people to the mailing list
for bug reports there, and we can update the Authors section
to give credit to the major contributors and point to
shortlog and blame for more information.
Each page has a "This is part of git" footer, so people can
follow that to the main git manpage.

"git diff --cached" (without revision) used to mean "git diff --cached
HEAD" (i.e. the user was too lazy to type HEAD). This "correctly"
failed when there was no commit yet. But was that correctness useful?
This patch changes the definition of what particular command means.
It is a request to show what _would_ be committed without further "git
add". The internal implementation is the same "git diff --cached HEAD"
when HEAD exists, but when there is no commit yet, it compares the index
with an empty tree object to achieve the desired result.

synopsis to match the lines given in the synopsis.

Since the git-* commands are not installed in $(bindir), using
"git-command <parameters>" in examples in the documentation is
not a good idea. On the other hand, it is nice to be able to
refer to each command using one hyphenated word. (There is no
escaping it, anyway: man page names cannot have spaces in them.)
This patch retains the dash in naming an operation, command,
program, process, or action. Complete command lines that can
be entered at a shell (i.e., without options omitted) are
made to use the dashless form.
The changes consist only of replacing some spaces with hyphens
and vice versa. After a "s/ /-/g", the unpatched and patched
