portage.package.ebuild._config.VirtualsManager module¶
- class portage.package.ebuild._config.VirtualsManager.VirtualsManager(*args, **kwargs)¶
Bases:
object
- _compile_virtuals()¶
Stack installed and profile virtuals. Preference for virtuals decreases from left to right. Order of preference: 1. installed and in profile 2. installed only 3. profile only
- _populate_treeVirtuals(vartree)¶
Initialize _treeVirtuals from the given vartree. It must not have been initialized already, otherwise our assumptions about immutability don’t hold.
- _read_dirVirtuals(profiles)¶
Read the ‘virtuals’ file in all profiles.
- add_depgraph_virtuals(mycpv, virts)¶
This updates the preferences for old-style virtuals, affecting the behavior of dep_expand() and dep_check() calls. It can change dbapi.match() behavior since that calls dep_expand(). However, dbapi instances have internal match caches that are not invalidated when preferences are updated here. This can potentially lead to some inconsistency (relevant to bug #1343).
- get_virts_p()¶
- getvirtuals()¶
Computes self._virtuals if necessary and returns it. self._virtuals is only computed on the first call.
- populate_treeVirtuals_if_needed(vartree)¶
Initialize _treeVirtuals if it hasn’t been done already. This is a hack for consumers that already have an populated vartree.
