Hello, all. Since the tree is still full of too broad dependencies and other mistakes, I would like to add a repoman check and a matching QA policy regarding how slots should be used in dependencies.
The check would apply to EAPI 5 and newer ebuilds only. Considering the past uproar against having slotted dependencies against single-slot packages, it would apply only to dependencies that match more than one slot of a package. With the new policy, the simple form of dependencies: dev-libs/foo would be only allowed if dev-libs/foo has only one slot. If the atom matches more than one slot of a package, one of the following forms would need to be used: 1. dev-libs/bar:* -- if any version of bar is acceptable, and you can replace bar:1 with bar:2 without rebuilding, 2. dev-libs/bar:= -- if any version of bar is acceptable, and you need to rebuild bar when changing slots (and subslots), 3. dev-libs/bar:slot -- if a single slot of bar is acceptable, and you can change subslots without rebuilding, 4. dev-libs/bar:slot= -- if a single slot of bar is acceptable, and you need subslot rebuilds, 5. dev-libs/bar:slot/subslot -- if a single subslot of bar is acceptable, useful mostly for binary packages and pass-through virtuals. ...which means that the only 'new' requirement would be that ':*' operator becomes mandatory in favor of plain deps that have semi- -undefined behavior. It should be noted that the check uses complete dependency atom to count the number of slots. That is, a dependency alike: >=x11-libs/gtk+-3.4 would match only one slot and cause no repoman warnings. This is mostly intended to keep the check simple and avoid false positives. If anyone wishes to test the current code, the last version of patch can be found at [1]. It will likely hit portage in -9999 as soon as dol-sen approves it. [1]:http://article.gmane.org/gmane.linux.gentoo.portage.devel/4369 -- Best regards, Michał Górny
