The quick summary:
You should almost never have to use the
--no-versionscommand-line options anymore.
doOverwriteconfiguration options have been removed from
coaddDriver.py, and the default behavior for both tasks is to always reprocess and write new outputs.
To skip steps for which the outputs already exist (the old default behavior), use the same output repository and pass
--reuse-outputs-from allon the command line.
We now only compare and require consistency in configurations, catalog schemas, and software versions when those are present in the output data repository, not the input repository. It’s now expected that a new output repository will have different configurations (etc) from its input. The only times you’re expected to need
--no-versionsis when you’re using an output repository as a sort of scratch space for repeated throwaway runs with different configurations (etc).
coaddDriver.pytasks only skip steps when both the
--reuse-outputs-fromoption is used and the outputs of those steps are present in the output repository. There is no longer a way to skip steps when outputs are present only in an input repository (this seems to have only ever happened by accident in the past).
--reuse-outputs-fromoption accepts a single argument, which is the name of a subtask (the same name used in the configuration tree, e.g.
makeCoaddTempExp) or the special value
all. All steps up to and including that step will be skipped when their outputs are present. Passing
allis equivalent to passing the last subtask in the driver (i.e.
