overrideFlavor(oldFlavor, newFlavor, mergeType=2)
Performs overrides of flavors as expected when the new flavor is specified by a user -- the user's flavor overrides use flags, and if the user specifies any instruction sets, only those instruction sets will be in the final flavor.

source code

_mergeDeps(depList, mergeType)
Returns a new Dependency which merges the flags from the two existing dependencies.

source code

mergeFlavorList(flavors, mergeType=1)

source code

mergeFlavor(flavor, mergeBase)
Merges the given flavor with the mergeBase - if flavor doesn't contain use flags, then include the mergeBase's use flags.

source code

filterFlavor(depSet, filters)

source code

_filterDeps(depClass, dep, filterDeps)

source code

getInstructionSetFlavor(flavor)

source code

formatFlavor(flavor)
Formats a flavor and returns a string which parseFlavor can handle.

source code

parseFlavor(s, mergeBase=None, raiseError=False)

source code

parseDep(s)
Parses dependency strings (not flavors) of the format (<depClass>: dep[(flags)])* and returns a dependency set containing those dependencies.

source code

flavorDifferences(flavors, strict=True)
Takes a set of flavors, returns a dict of flavors such that the value of a flavor's dict entry is a flavor that includes only the information that differentiates that flavor from others in the set

source code

compatibleFlavors(flavor1, flavor2)
Return True if flavor1 does not have any flavor that switches polarity from ~foo to ~!foo, or foo to !foo, and flavor1 does not have any architectures not in flavor2 and vice versa.

ThawFlavor(frz)

source code

PUBLIC API

Parameters:

frz - the frozen representation of a flavor

Returns: deps.deps.Flavor

a thawed Flavor object

Decorators:

@api.publicApi

Raises:

TypeError - could be raised if frozen object is malformed
ValueError - could be raised if frozen object is malformed

overrideFlavor(oldFlavor, newFlavor, mergeType=2)

source code

Performs overrides of flavors as expected when the new flavor is specified by a user -- the user's flavor overrides use flags, and if the user specifies any instruction sets, only those instruction sets will be in the final flavor. Flags for the specified instruction sets are merged with the old flavor.

_mergeDeps(depList, mergeType)

source code

Returns a new Dependency which merges the flags from the two existing dependencies. We don't want to merge in place as this Dependency could be shared between many objects (via a DependencyGroup).

mergeFlavor(flavor, mergeBase)

source code

Merges the given flavor with the mergeBase - if flavor doesn't contain use flags, then include the mergeBase's use flags. If flavor doesn't contain an instruction set, then include the mergeBase's instruction set(s)

parseDep(s)

source code

Parses dependency strings (not flavors) of the format (<depClass>: dep[(flags)])* and returns a dependency set containing those dependencies. Raises ParseError if the parsing fails.

flavorDifferences(flavors, strict=True)

source code

Takes a set of flavors, returns a dict of flavors such that the value of a flavor's dict entry is a flavor that includes only the information that differentiates that flavor from others in the set

Parameters:

strict - if False, ignore differences between flags where the difference is in strength of the flag, but not in direction, e.g. ignore ~foo vs. foo, but not ~foo vs. ~!foo.
