[CentOS-devel] including 3rd party repo release RPMs in Extras

Sun Mar 29 15:45:39 UTC 2015

Hi,

Le 28/03/2015 21:32, Carl George a Ã©crit :
> CentOS users have easy access to the EPEL repo because the epel-release RPM is in the CentOS Extras repository.  Obviously CentOS and EPEL have a special relationship, since they are both sponsored by Red Hat.  A coworker suggested to me that it would be nice if the ius-release RPM could be included in Extras as well.  I brought the idea up in IRC, and Karanbir suggested I draft up a specification that any third party repository can follow to be considered for inclusion.  Here is what I have so far.

 * Must not automatically install, upgrade,
  or replace stock distribution packages when the repository is enabled.

Problem: lot of packages is repositories following this RFC provides the
same "virtual" to be able to be a drop-in alternative for base packages.

Ex:

$ rpm -qp --provides php-mysql-5.3.3-40.el6_6.x86_64.rpm
php-mysql = 5.3.3-40.el6_6
php-mysqli
...

$ rpm -qp --provides php56u-mysqlnd-5.6.7-1.ius.el6.x86_64.rpm
php-mysql = 5.6.7-1.ius.el6
php-mysqli = 5.6.7-1.ius.el6
...

What happen if someone (or a package dep.) try to pull php-mysqli ?
Yum is unable to select the correct package.

So the rule, from the RFC is not honored.

More, there is a lot of 3rd party repository, most of them are not
designed to be compatible with others (usually only with base + epel).

Sometime, users install a lot of these 3rd party repositories, and
create terrible mess in their system. If CentOS is going to add "some"
3rd party repositories configuration, I think this will encourage users
to enable them, and thus result in more mess.

Remi.

P.S. exemple of such issue, on an fresh C6 installation:

# yum --enablerepo=ius install phpMyAdmin

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
