Bug 374261

*** Bug 375191 has been marked as a duplicate of this bug. ***

In previous Fedoras exists package called "bind-sdb". It was standard named +
compiled in database backends. I've merged bind + bind-sdb to one package.
Reasons are easier configuration and easier maintenance. Yes, I know named needs
database servers client libraries but I don't think that matter. If you have any
arguments why database backend should be in separate package (please not "I need
+10MB of disk space" - nowaday it is not argument). I'm going to replace mysql +
postgresql + other DBs dependencies with *-libs packages. Update will be
released when 9.5.0-a7 comes (should be during 2 weeks).

I need +10MB of disk space ;)

Standard reason: MySQL + PostgreSQL are non trivial dependencies which are not
required by named's core functionality.  Every additional + unneeded bit of code 

* requires additional disk space
* requires special attention regarding security issues
* can/will cause problems during updates

I'm primarily worried about conflicts with the MySQL-* packages from mysql.com I
already have installed. Before now, nothing depended on Fedora's mysql-* packages.

Actually, instead of depending on "mysql-libs" specifically, could it be made to
depend on "libmysqlclient.so.XX", like the "php-mysql" package currently does?
This should allow any vendor's MySQL packages to satisfy the dependency.

I expected answer like this :)

Yes, but nowadays it doesn't matter

- I disagree with you. If you have compiled in database backend and you doesn't
use it that part of code is never executed. And if yes it means that named code
already has been exploited on different place. And if this happen (pretty
unlikely) named without database libs can't save you.

Yes, the best solution.

it matters... nowadays, most servers are virtualized and have only one service
per instance.  10MB can be 5% of the really needed space and such a waste is
nothing which I can accept.

And... often the -libs have additional deps resp. these deps are out of control
of the original packager. So, you will probably end with more than 10MB.

Hence, please follow the principle to split non-trivial deps into own
subpackages when they are not needed for core functionality.

I forgot:  most of explicit Requires: are bad.  rpm does an excellent job in
detecting required libs so Requires: should be written sparely.  Please use
'comps.xml' to specify use-cases.

I've pushed bind-9.5.0-17.a7.fc8 to updates-testing. In the end I moved database
backends to bind-sdb. So if you need named with DB you should only install
bind-sdb package. bind-sdb also has no explicit dependencies to mysql-libs etc

bind-9.5.0-17.a7.fc8 has been pushed to the Fedora 8 testing repository.  If problems still persist, please make note of it in this bug report.
 If you want to test the update, you can install it with 
 su -c 'yum --enablerepo=updates-testing update bind'

Works for me. Thanks.
