Packages that depend on mysql-python and don't allow mysqlclient: app-admin/diamond app-admin/glance app-admin/salt app-backup/holland-lib-mysql app-text/bibus dev-db/percona-server dev-db/SchemaSync dev-python/adodb-py dev-python/atpy dev-python/django dev-python/oslo-db dev-python/pSQL dev-python/python-openid dev-python/pyzor dev-python/rdflib dev-python/sqlalchemy dev-python/sqlobject dev-python/storm dev-vcs/mercurial media-plugins/mythplugins media-tv/mythtv net-print/pykota sys-auth/keystone sys-cluster/cinder sys-cluster/neutron sys-cluster/nova www-apps/trac www-apps/viewvc There are currently two packages with an existing || dependency on mysql-python and mysqlclient: net-analyzer/graphite-web net-analyzer/netdata (In reply to Hanno Boeck from comment #0) > It seems development on mysql-python has stalled, but mysqlclient is a fork > which can be used as a drop-in replacement. mysql-python is python2-only, > while mysqlclient can be used in both python2/3. mysql-pyhton and > mysqlclient block each other and can't be installed in parallel. > > There are many packages in the tree that depend on mysql-python, therefore > moving from mysql-python to mysqlclient is currently impractical for most > users. > > Therefore probably all packages depending on mysql-python should change > their dependencies to something like "|| ( dev-python/mysqlclient > dev-python/mysql-python )". How can we proceed on that? I would suggest a virtual, as this is general less messy and hides the || ( ) ugliness. Furthermore, it is less prone to getting the order in || ( ) specifiers wrong. Any progress on this thread? As more and more apps are moving to python3, it's better to implement this ASAP, thanks. If mysqlclient is really a drop-in replacement, I'd rather not waste time on virtuals. What we really need is keywording and stabilization of mysqlclient, and working tests would be really helpful with that.

We're using trac, after replace mysql-python by mysqlclient, and no problem found until now.

Problem found: ~ # emerge -pv =dev-python/rdflib-4.2.2 These are the packages that would be merged, in order: Calculating dependencies... done!

This is the solution I'm using. It's really nice to replace mysql-python by mysqlclient in portage officially. Would be nice if we could make some progress: dev-python/mysql-python won't work with >=virtual/libmysqlclient-21 anymore (bug 632578). However, dev-python/mysqlclient isn't keyworded on all arches yet (looking at you, alpha), so we cannot just replace mysql-python with mysqlclient yet. The only two deps on mysql-python left are in old percona-server and optfeature in sqlalchemy (that might be outdated). |
