Subject: please add multi-arch support for libxml2

Date: Mon, 26 Sep 2011 20:03:30 +0300

[Message part 1 (text/plain, inline)]

Package: libxml2 
Version: 2.7.8.dfsg-4
Severity: normal
User: debian-dpkg@lists.debian.org
Usertags: multiarch
Tags: patch

Hi,

The following patch converts libxml2 to multiarch directories (by modifyin rules)
and adds needed Multi-Arch: stanzas to control file. dpkg-dev build-dep was dropped
as debhelper > 8.1.3 already pulls newer dpkg-dev in.

"Multi-Arch: same" packages must have identical files installed to same path, for
this reason /usr/bin/xml2-config is modified to get rid the arch-specific libdir.
Since the linked will search the multiarch path anyways, no functionality is lost.

The patch also adds an udeb which i'm not convinced we need. Also note
that I refrained from switching libxml2 to multiarch because of the
number of rdeps depending on its location in /usr/lib, thanks to .la
files.

I did not add it. I think it got added automatically as I had a ubuntu
host (the actual build was in sid pbuilder of course).

I'll try to check later this week how widespread this still is.

The rest foo.la (tulip, illuminator, subtitleeditor, opensync-plugin*) that referred 
to libxml2.la were lafiles unused by anyone (no reverse dependencies). That is also
probably true for the python-* bugs blocking above. The only really important bug above
is the gstreamer one, eg #633319

Cheers,
Riku

Hi,

All bugs marked as blocking libxml2's Multi-Arch has been resolved, so
I suggest to revisit this report.

Package: libxml2-dev
Followup-For: Bug #643026

Hello,

Due to lack of multiarch support in libxml2 I cannot install wine.

What is needed to upload a multiarch version of libxml2?

Thanks

Michal

tags 643026 - patch
thanks

I'm removing the tag of patch, because the patch has some problems so
it can't be applied.

1.This patch changes usr/bin/xml2-config at build time, but mark
libxml2-dev as "M-A: same", which is wrong. "M-A: same" requires
either path names with tripplet, or byte-to-byte identical across all
architectures.

2.This patch also modifies the build flag of python-libxml2, which
isn't mentioned (I'm not tested if this part works), see #664107.

3.".la file" aren't removed (but emptied) in the same patch, but I see
no reason to keep it anymore.

Closes: 643026 664107 668672
Changes: 
 libxml2 (2.7.8.dfsg-9) unstable; urgency=low
 .
   * Multi-Arch ready. (Closes: #643026)
     - M-A:same packages are libxml2, libxml2-dev and libxml2-dbg.
     - M-A:foreign package is libxml2-utils, others are not M-A.
     - Library files in udeb are still placed under usr/lib directly.
   * New binary: libxml2-utils-dbg.
     Move debuggings symbols of libxml2-utils binaries to another package
     in favor of marking libxml2-dbg as M-A: same. Descriptions of related
     binary packages are slightly modified.
   * Enable hardening for Python modules. (Closes: #664107)
   * Add support for build-arch and build target, essentially make the
     package not FTBFS anymore. (Closes: #668672)
   * Use dh compat 9. Not hardcoding libdir in debian/rules.
   * Port to source format 3.0 to ease future maintenance of patches.
     - Old patches are stored in 01_historical_changes.patch
     - Do not patch Makefile.in directly, use dh_autoreconf with patches to
       configure.in and Makefile.am instead. This will not actually make
       bootstraping a new architecture more difficult since we already have
       gettext and autoconf in deep B-D, porters need to break it anyway.
     - Store doc/examples/index.html in patch to avoid ciculate B-D with
       xsltproc, we should not B-D on it.
   * debian/*.dirs: removed, useless.
