Known Subclasses:

SConf.SConfBuildInfo

This is info loaded from sconsign.

Attributes unique to FileBuildInfo:

dependency_map : Caches file->csig mapping: for all dependencies. Currently this is only used when using MD5-timestamp decider. It's used to ensure that we copy the correct csig from previous build to be written to .sconsign when current build is done. Previously the matching of csig to file was strictly by order they appeared in bdepends, bsources, or bimplicit, and so a change in order or count of any of these could yield writing wrong csig, and then false positive rebuilds

setattr(self, key, value)

source code

x.__setattr__('name', value) <==> x.name = value

Overrides: object.__setattr__: (inherited documentation)

convert_from_sconsign(self, dir, name)

source code

Converts a newly-read FileBuildInfo object for in-SCons use

For normal up-to-date checking, we don't have any conversion to perform--but we're leaving this method here to make that clear.

convert_to_sconsign(self)

source code

Converts this FileBuildInfo object for writing to a .sconsign file

This replaces each Node in our various dependency lists with its usual string representation: relative to the top-level SConstruct directory, or an absolute path if it's outside.

prepare_dependencies(self)

source code

Prepares a FileBuildInfo object for explaining what changed

The bsources, bdepends and bimplicit lists have all been stored on disk as paths relative to the top-level SConstruct directory. Convert the strings to actual Nodes (for use by the --debug=explain code and --implicit-cache).
