I'm removing the transition tag for now, feel free to add that (and reassign)
once this is uploaded.

[ Note that I haven't actually reviewed the debdiff. ]

Hello,

this is a debdiff which we uploaded to Ubuntu (aside from some formal
debian/changelog differences). As debian/rules is really complex and I
don't have a good way of testing this, I'd appreciate a second look
before uploading this.

Thanks,

Martin

Bug#791238: petsc: library transition may be needed when GCC 5 is the default

2015-07-03 Thread Matthias Klose 
Package: src:petsc
Version: 3.4.2.dfsg1-8.1
Severity: important
Tags: sid stretch
User: debian-...@lists.debian.org
Usertags: libstdc++-cxx11

Background [1]: libstdc++6 introduces a new ABI to conform to the
C++11 standard, but keeps the old ABI to not break existing binaries.
Packages which are built with g++-5 from experimental (not the one
from testing/unstable) are using the new ABI.  Libraries built from
this source package export some of the new __cxx11 or B5cxx11 symbols,
and dropping other symbols.  If these symbols are part of the API of
the library, then this rebuild with g++-5 will trigger a transition
for the library.

What is needed:

 - Rebuild the library using g++/g++-5 from experimental. Note that
   most likely all C++ libraries within the build dependencies need
   a rebuild too. You can find the log for a rebuild in
 https://people.debian.org/~doko/logs/gcc5-20150701/
   Search for BEGIN GCC CXX11 in the log.

 - Decide if the symbols matching __cxx11 or B5cxx11 are part of the
   library API, and are used by the reverse dependencies of the
   library.

 - If there are no symbols matching __cxx11 or B5cxx11 in the symbols
   forming the library API, you should close this issue with a short
   explanation.
 
 - If there are no reverse dependencies, it should be the package
   maintainers decision if a transition is needed.  However this might
   break software which is not in the Debian archive, and built
   against these packages.

 - If a library transition is needed, please prepare for the change.
   Rename the library package, append v5 to the name of the package
   (e.g. libfoo2 - libfoo2v5). Such a change can be avoided, if you
   have a soversion bump and you upload this version instead of the
   renamed package.  Prepare a patch and attach it to this issue (mark
   this issue with patch), so that it is possible to NMU such a
   package. We'll probably have more than hundred transitions
   triggered. Then reassign the issue to release.debian.org and
   properly tag it as a transition issue, by sending an email to
   cont...@bugs.debian.org:
   
 user release.debian@packages.debian.org
 usertag this issue + transition
 block this issue by 790756
 reassign this issue release.debian.org
   
 - If unsure if a transition is needed, please tag the issue with help
   to ask for feedback from other Debian developers.

The libstdc++6 transition will be a large one, and it will come with a
lot of pain.  Please help it by preparing the follow-up transitions.
