Description Hiro Asari 2013-06-28 14:22:24 UTC

Description of problem:
If a single embeddable cartridge provides multiple versions of the same software (e.g., postgresql-8.4 and postgresql-9.2) it is conceivable to add a second cartridge to the same application.

In the case of postgresql, the second one will fail, because the first one has already created a database with the name $OPENSHIFT_APP_NAME. However, not all cartridges may fail similarly, and could lead to unexpected results.

Comment 1 Jhon Honce 2013-06-28 15:05:30 UTC

It was determined earlier that supporting two versions of any cartridge within one gear or application would not be supported.

Comment 2 Hiro Asari 2013-06-28 16:31:33 UTC

This is not about supporting it. I agree that it is not a good idea.

Rather, we would want to detect that such a maneuver is attempted, and inform the user with a meaningful message, rather than rely on each cartridge to fail somehow.

Comment 3 Hiro Asari 2013-07-03 13:56:54 UTC

This should be more gracefully disallowed. Currently it is possible to get around this loose restriction with CLI (see https://bugzilla.redhat.com/show_bug.cgi?id=980760 and https://bugzilla.redhat.com/show_bug.cgi?id=980739).

Reopening and sending this to the broker team for further consideration.

Comment 4 Hiro Asari 2013-07-05 15:35:42 UTC

Since v2 cartridge dropped the version suffix fromt the directory name, multiple versions will install to the same directory, causing strange problems.

Closing this as duplicate.
