Functions

_expand_new_virtuals(mysplit, edebug, mydbapi, mysettings, myroot=u'/', trees=None, use_mask=None, use_force=None, **kwargs)
In order to solve bug #141118, recursively expand new-style virtuals so as to collapse one or more levels of indirection, generating an expanded search space. source code

dep_eval(deplist)

source code

dep_zapdeps(unreduced, reduced, myroot, use_binaries=0, trees=None)
Takes an unreduced and reduced deplist and removes satisfied dependencies.

source code

dep_check(depstring, mydbapi, mysettings, use=u'yes', mode=None, myuse=None, use_cache=1, use_binaries=0, myroot=None, trees=None)
Takes a depend string, parses it, and selects atoms. source code

dep_wordreduce(mydeplist, mysettings, mydbapi, mode, use_cache=1)
Reduces the deplist to ones and zeros

_expand_new_virtuals(mysplit, edebug, mydbapi, mysettings, myroot=`u'/'`, trees=None, use_mask=None, use_force=None, **kwargs)

source code

In order to solve bug #141118, recursively expand new-style virtuals so as to collapse one or more levels of indirection, generating an expanded search space. In dep_zapdeps, new-style virtuals will be assigned zero cost regardless of whether or not they are currently installed. Virtual blockers are supported but only when the virtual expands to a single atom because it wouldn't necessarily make sense to block all the components of a compound virtual. When more than one new-style virtual is matched, the matches are sorted from highest to lowest versions and the atom is expanded to || ( highest match ... lowest match ).

dep_zapdeps(unreduced, reduced, myroot, use_binaries=0, trees=None)

source code

Takes an unreduced and reduced deplist and removes satisfied dependencies. Returned deplist contains steps that must be taken to satisfy dependencies.

dep_check(depstring, mydbapi, mysettings, use=`u'yes'`, mode=None, myuse=None, use_cache=1, use_binaries=0, myroot=None, trees=None)

source code

Takes a depend string, parses it, and selects atoms. The myroot parameter is unused (use mysettings['EROOT'] instead).
