[FFe] libapache2-svn missing in saucy

[klockren]

[FFe]

libapache2-svn was dropped in Debian to unblock the Apache 2.4 transition. This was an intentional regression.

Patches have been in Debian BTS for a while, and a DD has now uploaded a delayed NMU for it. (The package is now libapache2-mod-svn).

I'd like to cherry-pick this change for Saucy, but only if the NMU lands. The patch against the NMU notice in Debian BTS looks good. But since this involves a "new" binary package, I don't have visibility of the exact canonical patch yet. But I will make sure that what I cherry-pick only impacts the new binary package, and test it myself.

Impact: we will completely regress the Subversion Apache module if we do not fix this. Regression risk: as long as we're only impacting the new binary package, I don't see that we can make the situation worse. I will need to check carefully that this will only impact the new binary package.

[Original Description]

The package does not exist in saucy - and mod_dav_svn.so is not provided by any other package.

See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=712004 and http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=666794. Debian intentionally removed libapache2-svn to unblock the transition to apache 2.4.

libapache2-svn has always been in universe in Ubuntu, so needs volunteers to help Debian fix this.

[Robie Basak (racb)]

Debian's changelog entry was:

   * Stop building libapache2-svn (closes: #712004, #666794).

[klockren (jonas-almroth)]

Fedora 19 seem to successfully have built Subversion against Apache 2.4.
By copying all libsvn*.so* modules, mod_authz_svn.so and mod_dav_svn.so from a Fedora 19 installation, subversion is working nicely in Apache 2.4 on my Ubuntu box. The dav_svn.load and .conf files where still in /etc/apache2/mods-available since before the upgrade raring->saucy.

[Robie Basak (racb)]

Right - it does look like a patch is available, but I think some packaging work is needed in Debian to rejig things for the packaging changes in the apache2 2.4 transition, too.

[Shake (shake234)]

This is critical for everybody hosting a subversion repository... So please fix this before reaching beta.

[Shake (shake234)]

@klockren: I tried to copy the files from Fedora.
But unfortunately I run into:

Cannot load /usr/local/lib/apache2/modules/mod_dav_svn.so into server: libsvn_repos-1.so.0: cannot open shared object file: No such file or directory

I have downloaded that lib and copied into /usr/local/lib

But obviously something is going wrong. Any hints?

[Shake (shake234)]

Okay: I did the following.

Under "/usr/lib/x86_64-linux-gnu" I created symlinks for the libs that are given within the error message.
The Fedora files expect each library so be available as "*.so.0" while they only the "*.so.1" symlinks are available.

Afterwards I had to install "libdb5.3"

Now it seems to work...

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Robie Basak (racb)]

I've uploaded a test package based on the NMUs in Debian by James McCoy. I've also added a dep8 test. Binary packages should build and be ready soon. If someone can test them, that would be appreciated.

Before this can land in Saucy, we need:

1) The feature freeze exception approved by the release team.

I would also prefer:

2) The NMU to land in Debian.
3) To verify that the NMU that lands is identical to the patch I've picked up from Debian BTS (for nmu5) and the breaks/replaces line matches what I've done, except for Ubuntu versioning differences (for nmu6).

[Robie Basak (racb)]

Uploaded to my PPA that is: https://launchpad.net/~racb/+archive/experimental

[Martin Kunkel (ma-ku)]

Tested subversion apache2 module from https://launchpad.net/~racb/+archive/experimental:
- Ubuntu saucy i386
- Apache/2.4.6 (Ubuntu)
- libapache2-mod-svn 1.7.9-1+nmu3ubuntu2~ppa2

Installation and execution of apache2 module works without any problems.

[Robie Basak (racb)]

Martin, thanks for the testing!

The Debian NMU has landed and I've verified that it's the same as the update I prepared in my PPA.

Save for a release team ack, this is now ready to land in Saucy. Debdiff attached.

[Adam Conrad (adconrad)]

Provision ACK, but I'd prefer this to be a merge that includes nmu4 as well, not just a cherrypick of nmu5.

[Robie Basak (racb)]

I've prepared a merge. Debdiffs attached. This passes against the dep8 test I wrote previous and include here.

[Launchpad Janitor (janitor)]

This bug was fixed in the package subversion - 1.7.9-1+nmu6ubuntu1

---------------
subversion (1.7.9-1+nmu6ubuntu1) saucy; urgency=low

  * Merge from Debian unstable. Remaining changes:
    - Create pot file on build.
    - debian/rules: Manually create the doxygen output directory, otherwise
      we get weird build failures when running parallel builds.
    - Build a python-subversion-dbg package.
    - Build-depend on python-dbg.
    - Build-depend on default-jre-headless/-jdk.
    - only build on requested python versions (X-Python-Versions:)
    - Do not apply java-build patch.
    - Drop svn2cl to Suggests; we don't particularly need it in Ubuntu main
  * Includes changes from Debian nmu5 and nmu6 to restore the Apache module
    (LP: #1209493). Thanks to James McCoy for the Debian NMUs.
  * d/tests/libapache2-mod-svn: add dep8 test for Apache functionality.
