[PATCH 0/4] [PULL] ab/i18n-prereqs, prerequisites for ab/i18n

[Ævar Arnfjörð Bjarmason]

These are the first four patches in the ab/i18n series which aren't
strictly related to it, but merely fixes to issues I encountered.

I'm submitting these separately now in the hope that they'll make it
to the next & master branches before ab/i18n. Having these separately
reviewed should be easier for everyone.

These patches can also be fetched from:

  Makefile: move "Platform specific tweaks" above LIB_{H,OBJS}
  t7004-tag.sh: re-arrange git tag comment for clarity
  tests: use test_cmp instead of piping to diff(1)
  builtin: use builtin.h for all builtin commands

[PATCH 1/4] Makefile: move "Platform specific tweaks" above LIB_{H,OBJS}

[Ævar Arnfjörð Bjarmason]

Change the Makefile so that the "Platform specific tweaks" section
comes before the assignments to LIB_H and LIB_OBJS.

In the ab/i18n series I only want to build gettext.o (by adding it to
LIB_OBJS) if NO_GETTEXT is unset. It's not possible to do that without
an ugly hack if we haven't applied our platform specific tweaks before
LIB_{H,OBJS} gets assigned to.

See <201008140002.40587.j6t@kdbg.org> (subject: "[PATCH] Do not build
i18n on Windows.") for Johannes's original report, and my follow-up in
<AANLkTiku5R+idX-C8f0AcCikBLmfEb5ZEhdft+CSRzU0@mail.gmail.com> where I
suggested that the problem be solved in the manner of this patch.

[PATCH 2/4] t7004-tag.sh: re-arrange git tag comment for clarity

[Ævar Arnfjörð Bjarmason]

Split the "message in editor has initial comment" test into three
tests. The motivation is to be able to only skip the middle part under
NO_GETTEXT_POISON.

In addition the return value of 'git tag' was being returned. We now
check that it's non-zero. I used ! instead of test_must_fail so that
the GIT_EDITOR variable was only used in this command invocation, and
because the surrounding tests use this style.

[PATCH 3/4] tests: use test_cmp instead of piping to diff(1)

[Ævar Arnfjörð Bjarmason]

Change submodule tests that piped to diff(1) to use test_cmp. The
resulting unified diff is easier to read.

[PATCH 4/4] builtin: use builtin.h for all builtin commands

[Ævar Arnfjörð Bjarmason]

Change the builtin/*.c files and wt-status.c files which weren't using
builtin.h to use it, also remove any git-compat-util.h, strbuf.h and
cache.h from those files. We can trust on builtin.h including them.

builtin.h also includes commit.h and notes.h. But I haven't removed
these includes. They're redundant now, but we may want to remove them
from builtin.h in the future.

This impeded my efforts to gettextize git, since I'd otherwise have to
add gettext.h to all of these. Using builtin.h is a good idea in any
case, since it's defining the prototypes for the cmd_* functions that
these files define.

Doesn't this suggest wt-status.c should be moved to builtin? Or
something like that.

It just suggests that the header was useful. But maybe it should be
moved to buildin/status.c.

Currently the Makefile is structured like this:

	A. default target
	B. basics
	   1. basic configuration section
	      a. -include GIT-VERSION-FILE and recipe to generate it
	      b. uname_S := $(shell uname -s) and similar variables
	      c. user-facing compilation variables: CFLAGS, LDFLAGS, STRIP
	      d. user-facing paths: prefix, bindir_relative, etc
	      e. program names: CC, AR, etc
	   2. basic cflags and ldflags (almost configurable)
	   3. main list of program targets:
	      SCRIPTS, PROGRAMS, TEST_PROGRAMS, BUILT_INS,
	      OTHER_PROGRAMS, BINDIR_PROGRAMS
	   4. defaults for SHELL_PATH, PERL_PATH, PYTHON_PATH
	   5. main list of library targets:
	      LIB_FILE, XDIFF_LIB, LIB_H, LIB_OBJS, BUILTIN_OBJS
	   6. GITLIBS, EXTLIBS for the linker command line
	   7. platform-specific tweaks
	   8. -include config.mak, config.mak.autogen
	C. preparations
	   1. handling of the various NO_THIS_OR_THAT options.
	      This affects BASIC_CFLAGS, COMPAT_CFLAGS,
	      COMPAT_OBJS, PROGRAMS, EXTLIBS, LIB_OBJ, LIB_H, etc
	   2. machinery for non-noisy build
	   3. shell-quoted and C-quoted variables
	   4. ALL_CFLAGS, ALL_LDFLAGS
	D. main build rules
	   1. all:: targets for the main build, subdirs
	   2. shell sanity check
	   3. building the git binary and built-ins
	   4. scripts and gitweb
	   5. autoconf
	   6. building objects:
	      a. %.o: %.c rule, header deps, dependency checking
	      b. target-specific -D flags
	   7. building non-builtins, remote-curl
	   8. libs
	   9. subdirs
	E. GIT-CFLAGS, GIT-BUILD-OPTIONS, GIT-GUI-VARS
	F. bin-wrappers
	G. tests
	H. installation rules
	I. maintainer's dist rules, check-doc, coverage, etc

This patch proposes moving A5 (main list of library targets) after
A8 (end of configuration).

This doesn't motivate the patch all all to me.  Is changing the list
of LIB_OBJS in section C1 really an ugly hack?  It is where
configuration-specific things go and how BLK_SHA1, PROGRAM_OBJS, etc
work already.

That said, I can see another reason to move A3 and A5 lower down in
the makefile.  Namely, they don't seem to have anything obvious to
do with configuration.  Including the basic list of objects that
high up may make the makefile easier to read straight through, but
I don't think anyone is reading it straight through.

So I wouldn't have anything against moving both A3 and A5 to right
before C1, I just think it needs different motivation.

Sensible?

Oh, okay.  I had the test_must_fail version sitting in my local tree
as part of the unsent part of the &&-chaining series

Nice.  Note that you've changed the semantics of the test here
(probably for the better): the $() backquoting operator strips
trailing newlines, while your sed expression does not.

I assume you've run the tests and made sure they still pass.

For what it's worth,

I think this tab should be spaces?  Also, shouldn't this be

	cat >expect <<EOF &&
	...
	EOF
	test_cmp expect actual

to match the others?  There are a few similar cases in the patch.

Yes, I think Junio acked this before, though I can't it in the archive.

Also compare: http://thread.gmane.org/gmane.comp.version-control.git/49523

IMHO this deserves a separate mention in the log message.  If it is
just to get gettext.h, why not include gettext.h directly?

Thank you!  Hopefully others can pitch in and extract more patches
like this from ab/i18n.

I've sent comments on all four patches.  I agree with the spirit
of all of them and would be happy to see them tweaked and integrated
soon (patch 2 does not even seem to need tweaking).

Yeah, because if it hadn't come before A8 it would have been *not*
assigned to in the first place like we do everywhere else. Moving A8
before A5 enables us to do that.

I was thinking about moving A3 & A5 further down. But since I just
needed A5 now I only ended up doing that. Moving them both would clean
things up though. I think we should do A8 as early as possible.

Erm, sorry for the gibberish.  For "all all", please read "at all"

Better to fix it up later IMO in something like your series. One

Yeah, I've been running all these (also the others in the series) for

work.

How about this?  An annoying piece of GNU makefile syntax makes this
uglier than it needs to be (search for HACK for details).

Why?  builtin.h is to declare cmd_foo() and to be included by files that
implement cmd_foo() (i.e. builtin/*.c) and the file that needs to see
cmd_foo() declarations (i.e. git.c).

wt-status.c is about giving common service routines for status related
commands in builtin/commit.c to implement both commit and status.  Its
services may have gained callers outside builtin/cocmmit.c, but that is
not a good reason to export its services via builtin.h nor for it to
include builtin.h.

This is a tangent but I think for the same reason the types and functions
related to notes-rewrite currently in builtin.h do not belong there; they
should be moved to notes.h or somewhere.

Isn't this similar to block-sha1, which is controlled by the feature macro
BLK_SHA1 that can be inferred from platform tweak?  The mechanism is not a
hack but is a way LIB_H and LIB_OBJS are intended to be used, so there
must be something missing in your explanation.

Hmm, in the existing platform specific tweaks section, we set BLK_SHA1
based on $(uname_S) and that symbol is used to control what is added to
LIB_H and LIB_OBJS.  Why is your gettext.o any different?

Hmm, I don't quite get what you are trying to do here.  What good does the
output from "make outline" do to a potential/actual developer?  You can
learn that there are sections for "Testing rules", but then what?  You
will look for that string in the editor or pager.

Or is this some sort of outline/org-mode hack?

I dunno.  I wrote it because Ævar asked for it (and to make visible
where the trivial obstacles would lie in getting target-listing "make help"
to work, which is more interesting to me).

I just meant that we should add your comment at the top at some point.

But doing it via something like outline is probably better in the long term.

But let's do it in another patch series :)

As I already said, buitlin/*.c is fine, but wt-status.c is very dubious.

What about non-builtin commands?  Don't they need to include gettext.h
anyway?

I would have expected that gettext.h would be included from cache.h, so
that all gitty commands, whether they are builtin or standalone, have
access to the symbols defined in it.

So I should resend this patch with `#include "gettext.h"` in
wt-status.c and the rest unchanged, along with a new commit message?

In my patch to add gettext infrastructure I add gettext.h to
imap-send.c and friends which have their own main.

I can do that too. I just got the impression previously that we wanted
to only include things in headers that made sense according to their
name. Gettext has nothing to do with the cache, and cache.h itself
doesn't need it.

But if we want to stick it in there that's fine by me, I just care
about the ends, not the means. So just say which way you want it and I
can cook up a patch.

A little bit of history: git was once called dircache.  cache.h is
practically speaking git.h, which is why it declares:

 - get_git_dir
 - ALLOC_GROW
 - zlib_compression_level
 - safe_crlf
 - mksnpath
 - git_pathdup
 - hashclr
 - validate_headref
 - peel_to_type
 - approxidate_careful
 - packed_git
 - path_match
 - fsync_or_die
 - setup_pager
 - checkout_fast_forward

to list a random assortment.  See "A birds-eye view of Git's source
code" in the user manual for more on this.
