RPM/Mash

Mash

Présentation

Mash est un outil qui interroge Koji afin d'obtenir les RPMs pour un tag donné et qui créer un dépôt directement utilisable avec ceux-ci.

Installation

yum install mash

Configuration

Configuration générale de mash

Fichier <path>/etc/mash/mash.conf</path>

[defaults]
configdir = /etc/mash
buildhost = http://koji.b2pweb.com/kojihub
repodir = file:///mnt/koji
use_sqlite = True
use_repoview = True

Configuration du dépôt pour CentOS 5

Par défaut, mash créé une somme de vérification avec l'algorythme sha256, ce qui est incompatible avec CentOS 5. On doit donc lui préciser d'utiliser l'algorythme sha1 en lieu et place.

Fichier <path>/etc/mash/centos5.mash</path>

Configuration du dépôt pour fedora 20

Le fichier existe déjà (installé en même temps que <app>mash</app>. Seul la version de fedora s'incrémente au fur et à mesure des sorties de la distribution.

Fichier <path>/etc/mash/branched.mash</path>

Mise en place d'un alias

Le répertoire <path>/mnt/repositories</path> doit être accessible par HTTP. On ajoute donc un alias.

Fichier <path>/etc/httpd/conf.d/mash.conf</path>

Alias /repositories "/mnt/repositories"
<Directory "/mnt/repositories">
        Options Indexes
        AllowOverride None
        Order allow,deny
        Allow from all
        Options +Indexes
        AllowOverride None
        <IfModule mod_authz_core.c>
                # Apache 2.4
                Require all granted
        </IfModule>
        <IfModule !mod_authz_core.c>
                # Apache 2.2
                Order allow,deny
                Allow from all

F.A.Q.

Erreur yum.Errors.RpmDBError: Package tuple could not be found in rpmdb

Cette erreur se rencontre après avoir mis à jour <package>yum</package>

Ce bug est répertorié chez RedHat

La correction est triviale, Il faut appliquer le patch suivant au fichier <path>/usr/lib/python2.6/site-packages/yum/depsolve.py</path>( _checkFileRequires() caches the file requires of installed or to-be installed packages. Update it when removing packages in TS_INSTALL_STATES from transaction).
