[PATCH 0/4] ruby: quick update before the freeze!

[PATCH 0/4] ruby: quick update before the freeze!

[Ali Polatel]

Hey David,

I've polished the small patch series I had lying around.
I believe I've covered all the lacking API changes.

In addition, the third patch fixes a long-standing bug about the build.

I've decided to send these to you and the list instead of committing right away
in case someone notices any quick errors. Otherwise, please commit these before
the freeze and make rubyists happy.

Ali Polatel (4):
  ruby: Add wrapper for notmuch_query_count_messages
  ruby: Add wrapper for notmuch_query_add_tag_exclude
  ruby: Add workarounds to use in-tree build not the installed one
  ruby: Add wrapper for notmuch_query_set_omit_excluded()

How has this ever worked?

libnotmuch.so links to many things, fortunately when linking Ruby's
notmuch.so binding to libnotmuch.so.3 all those dependencies are
resolved for us, but when you link to libnotmuch.a you need notmuch.so
to link against all those dependencies.

This is triggering cryptic errors such as:

/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require':
foo/notmuch.so: undefined symbol:
_ZTVN10__cxxabiv117__class_type_infoE - foo/notmuch.so (LoadError)

Presumably because not even libstdc++.so is linked.

I don't see how this patch could be fixed properly easily, and it was
labeled as a hack, and I didn't like it in the first place anyway, so
I'm going to revert it by tomorrow if I don't hear any good reason not
to.

I also suggest making a brown-paper-bag release 0.13.1 because 0.13
has completely unusable Ruby bindings; there's just no way to compile
them and make them work.

Cheers.

I think this highlights the need for at least a minimal test suite for
the ruby 

I do plan on a bug fix release, to fix an annoying emacs interface bug
if nothing else. I'd rather see a fix/revert coordinated with Ali in his
role as ruby bindings maintainer.

FWIW, the previous situation of linking with the installed version of
notmuch sounds somewhat broken as well, although obviously preferable to
not working at all.

Yeap, I thought the same.

Well, sure, if possible that would be best. But I doubt the ruby
bindings maintainer would complain about making the Ruby bindings work
again :)

Worst-case scenario we would end up with what we had before.

That would be only if there was installed version of notmuch, which
some people don't have (e.g. me).

Either way, to fix that particular problem we don't need to link to
the static library, we can just the right CFLAGS and LDFLAGS, in fact,
I wonder how is it that it's not working properly; AFAIK the linker
and compiler would use first the headers and libraries found in these
flags, and only as a fallback use the system ones, so if anybody has
managed to compile before (I have) the headers and libraries would be
in some -I/-L path.

I could try to investigate, but at the moment I still see no reason
not to revert.

Cheers.

Since I've seen no better alternatives to fix the problem, I've
reverted the patch and pushed to 'master'. Would be nice to pick it
for 'release'.

Cheers.

If I don't hear any objections over the weekend, I'll cherry-pick it on
monday, for a planned tuesday release of 0.13.1

Could you write a short announcement for NEWS? ideally as a patch
against release:NEWS
