[PATCH/WIP] git-svn: tweak log format to match "svn log" output

[PATCH/WIP] git-svn: tweak log format to match "svn log" output

[Jonathan Nieder]

From: Jens Seidel <jensseidel@users.sf.net>

Tweak "git svn log" output to more closely match what svn produces.
In particular, if Locale::gettext is available, use that to produce
localized output using svn’s translations.

So now instead of 

 git:
 r2105 | viktor | 2010-03-19 13:40:54 +0100 (Fr, 19 Mär 2010) | 2 lines
 
 svn:
 r2105 | viktor | 2010-03-19 13:40:54 +0100 (Fr, 19. Mär 2010) | 1 Zeile

we get the much closer

 git:
 r2105 | viktor | 2010-03-19 13:40:54 +0100 (Fr, 19. Mär 2010) | 2 Zeilen
 
 svn:
 r2105 | viktor | 2010-03-19 13:40:54 +0100 (Fr, 19. Mär 2010) | 1 Zeile

and a script for munging to compare logs would only have to fuzz
out the extra blank lines in git svn’s commit log.

[jn: made Locale::gettext dependency optional; added a test script]

Sorry to leave this hanging for so long.  I think it is an improvement
as is, but I have not tested in the following scenarios:

 - Locale::gettext not available
 - subversion not translated
 - subversion translated but not to the current language

And the extra blank line at the end of log messages remains unsolved.

Thoughts?

Hi Jens, Jonathan,

I just made an additional patch that should solve the problem
(see my reply to this email).

Everything looks reasonable to me.  gettext should just fall back to the
original string when a translation is not available.

I've squashed the following cleanup on top of Jens' original change:

[PATCH 2/1] git svn: remove extraneous newline from log output

[Eric Wong]

This is to match the output of "svn log", which does not
add an extra newline before the next log entry.

This change gives me pause: wouldn’t it be a problem in
non-English locales, where $sing_fmt changes before it is
used to set $plur_fmt?

Of course there is no problem because the code is equivalent to

		$sing_fmt = $d->get($sing_fmt);
		$plur_fmt = $d->get($plur_fmt);

(or at least Locale::gettext is advertised to work that way.)

Thanks Jonathan, that looks much better.  I'll squash that on top

No, this is still wrong, we have to use $d->nget as some languages can have
multiple plural forms. Russian e.g. has two: one if the last digit ends with
2-4 and a second one if it ends with 5-9. Exact rule:
"Plural-Forms:  nplurals=3; plural=(n%10==1 && n%100!=11 ? 0 : n%10>=2 &&
n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2);\n"

That's why it's wrong to use $plur_fmt at all (and also "10" from above
makes no sense). Let's use:
$d->nget(" | %d line", " | %d lines", $nr_line), $nr_line)
where $nr_line is the variable.

Sorry for not providing a patch now but I need more time ... I suggest one
of you try it again and I check it :-)

thanks for the patch but it doesn't work in the general case.

I attached a sample Subversion repository dump where the output of
git svn log and svn log still differs by empty lines.

I also noticed the following error:
Can't use an undefined value as an ARRAY reference at                                                                                            
/usr/lib/git-core/git-svn line 5717, <$fh> line 53.

I'm not sure whether I introduced this error once I patched
git-svn ...
The affected line is the second one in:
           } elsif (/^${esc_color}    (git-svn-id:.+)$/o) {
                        if (@{$c->{l}} && $c->{l}->[-1] eq "\n") {
                                pop @{$c->{l}};
                        }
(is -1 valid?)

Here is a new patch:

(Please check the last stanza, Jonathan introduced $nr_line for the
output where 1 was used before. I reverted it.)

Since the partial patches get difficult to handle I attached also the
combined patch which includes everything from this thread.

And a further minor issue. The current locale for the test is extracted from
$LANG. It's possible that this variable isn't set but another one such as
LC_MESSAGES. So the test doesn't determine the locale but $LANG :-))

Yes, -1 is valid but $c->{l} may not exist at that point..

But I had forgotten about a similar piece of code in the
"show_commit_normal" subroutine which does a similar job:

		while ($l->[$#$l] eq "\n" && $#$l > 0
		                          && $l->[($#$l - 1)] eq "\n") {
			pop @$l;
		}

This is partially because SVN doesn't enforce a trailing "\n" in
commit messages (unlike "git commit"), so we always append one
when we fetch and add "\ngit-svn-id: ...\n".  But then we also
need to take noMetadata users into account, too.

I'll let you ponder issues with this since you appear to care more than
I do about completely matching SVN output :)


For what it's worth, over the years, nobody ever "outed" me as a git-svn
user in SVN projects when I shared log output.  Some folks worked with
for years in the same offices and never made indication to knowing I
used git-svn (even after they started using it themselves).
