This patchset improves the caching of task file dependency checksums in two
ways. First, the patchset enables writing of the cache onto disk so that the
checksums can be re-used on subsequent runs of bitbake. Previously the task
signature checksums were calculated and cached in memory but never really
saved.
Second, this patchset makes the task file dependency checksum cache file
configurable. This is intended to be used e.g. with a further patchset for
oe-core that will utilize task file dependencies heavily.
[YOCTO #8853]
Markus Lehtonen (6):
bb/cache: drop some unused arguments
SignatureGenerator: add method for saving the file checksum cache
bb/runqueue: save task file dependency cache onto disk
FileChecksumCache: add get_checksums() method
MultiProcessCache: make cache filename configurable
SignatureGeneratorBasic: make checksum cache file configurable
