This patch series is an attempt to cleanup a bit the Makefile regarding asciidoc stuff. It does not enable asciidoctor direct manpage creation, that's in a separate patch.

By always specifying the output file it will be possible to refactor all the calls in a future helper.

The hacks to deal with interrupted builds is scattered throughout the Makefile, but not everywhere (it's not done for techical/ and articles). It originally comes from f9dae0d3e6 (Documentation/Makefile: fix interrupted builds of user-manual.xml, 2010-04-21), however, that description is not correct. asciidoc does actually remove the output file in case of an exception, but there was a bug that handled keyboard interruptions through a different path, and thus in that particular case the file is not removed[1]. We shouldn't overly complicate the Makefile due to bugs in asciidoc. In order to keep the Makefile clean this commit creates an asciidoc wrapper that does the job of tracking the intermediary output. Once asciidoc is fixed this helper can be safely removed and there would be minimal changes elsewhere. It's written for bash, but could easily be modified for something more portable.

It would be so nice if this worked, but here is what I saw in a
quick-and-dirty experiment:
$ f () { echo foo >"$1" && sleep 20 && echo bar >>"$1"; }
$ f hoi ;# wait sufficiently long
$ cat hoi
foo
bar
$ f hoi ;# wait a bit and hit ^C
^C
$ cat hoi
foo
$ rm hoi
$ f hoi || rm hoi ;# wait a bit and hit ^C
^C
$ cat hoi
foo
So, I suspect it unfortunately may not work well.
We need to get 2/8 redone without bash-ism, but it would not affect
the correctness of this step, I would think, whether this is done in
bash or implemented in a plain vanilla POSIX shell.
Thanks.

That's because the interrupt signal is not caught. This works: sh -c 'echo foo >"$1" && trap "exit 1" INT && sleep 20' test hoi || rm hoi And so does this: #!/bin/sh ruby - hoi <<EOF || rm hoi File.write(ARGV[0], 'foo') begin sleep(10) rescue Exception exit(1) end EOF Both asciidoc and asciidoctor trap the signal. > We need to get 2/8 redone without bash-ism, Yes, if we agree this approach is indeed desirable I can do that.

Both this and your first patch could just be made to use the .DELETE_ON_ERROR flag instead, although that's a bigger change. I had this and a related series for that recently: https://lore.kernel.org/git/patch-4.6-2ff6359c273-20210329T161723Z-avarab@gmail.com/ I don't think anyone had an objection to using that, I didn't pursue it because I was trying to make (among other things) AIX development less annoying, but Junio didn't like the -o $@+ && mv $@+ $@ pattern for object files, so I gave up on pursuing it. But if you're trying to address this "maybe it errors" issue then .DELETE_ON_ERROR is a better solution. I think if we use that we should also undo your changes to use "-o file" and instead pipe to the file ourselves, otherwise we'll probably have cases where the program that fails and GNU make will race to delete the file (but I haven't tested that case).

It seems this used to make sense around 7b8a74f39cb (Documentation:
Replace @@GIT_VERSION@@ in documentation, 2007-03-25), but at some point
(I didn't look further) we refactored that and kept the "rm".

I was a bit lazy in a15ef383e7 ("Documentation/Makefile: add missing dependency on asciidoctor-extensions", 2019-02-27). We end up with some duplication. We could pull GIT-ASCIIDOCFLAGS into some ASCIIDOC_DEPS_COMMON. But with just one such common dependency, it seems unnecessary and overly complicated. We can pull out the common dependencies when we actually gain something from it. Martin

Actually it came later: 50cff52f1a (When generating manpages, delete
outdated targets first., 2007-08-02).
I'm not sure we should complicate the Makefile just because somebody
made the mistake of doing 'sudo make doc' a long time. Especially since
other rules don't have this.
sudo make doc
touch GIT-ASCIIDOCFLAGS
make doc
Fails here already.

I really don't see what's the point of scattering all those rm mv all over the place. If the command is interrupted (ctrl+C), then make will remove the file anyway (regardless of .DELETE_ON_ERROR). It's only a problem if the command fails for some other reason, in which case the command itself should remove the file, or it's trapping the SIGINT signal incorrectly (as is the case with asciidoc). > But if you're trying to address this "maybe it errors" issue then > .DELETE_ON_ERROR is a better solution.
