New libmysqlclient transition necessary
Hello
There is another libmysqlclient transition coming so I like to inform
the release team about it.
In the last month there already was one where I tried to get rid of
libmysqlclient10/12/14 in favour of libmysqlclient15. Thanks to the versioned
symbols this was no big deal and was almost finished. Then came 5.0.19...

Here are my plans, please comment :)
1. Package changes:
* Change package names (without changing the library filename, of course):
libmysqlclient15 -> libmysqlclient15off
libmysqlclient15-dev -> libmysqlclient15off-dev
* libmysqlclient15off package gets:
Conflict: libmysqlclient15
Replaces: libmysqlclient15
* modifying rules:
dh_makeshlibs -plibmysqlclient15off -V'libmysqlclient15off (>= 5.0.19-1)'
* Add a short NEWS.Debian and long README.Debian warning that software
which was locally build against libmysqlclient15 has to be rebuild.
2. Upload now to experimental to check if all buildds eat it
3. Wait for the release-teams of to start the transition
(or may I start ASAP?)
4. File bug reports against all packages with severity=important
and user-tag "transition-libmysqlclient15-dev" (already present
on wiki.debian.org/OngoingTransitions).
5. Upload to unstable with prio=medium
6. Immediately NMU packages that were already linked against libmysqlclient15
with prio=high
(like libdbd-mysql-perl which mysql-server-5.0 depends on)
7. Keep an eye on the rest and NMU at will.
bye,
-christian-
