#10156 Configure Processes with Subsystems Issue created by stuhood There are a few different usecases for per-

Process

configuration: 1. temporarily disabling caching (the equivalent of

--cache[-scope]-ignore

) 2. configuring timeouts in a uniform way that is transparent to the engine and allows for explaining how to adjust them. 3. allowing a user to specify additional arguments on a temporary basis (this one is slightly scary, but useful for debugging) * * * This would involve at least two components: • Support for registering scoped-`Subsystem`s in rules. • Add an optional

Subsystem

reference to

Process

that would be consumed for timeout and cache values. Open questions: • how this relates to #9760 and #7735. • whether this is one subsystem or two: preserving the literal

--cache[-scope]-ignore

syntax would be great, but the other options related to processes are not cache related... ie:

--process[-scope]-timeouts

. • it's possible that a

process

Subsystem

would not be scoped... rather, subclassed. Because an unscoped

--process-extra-args

would not make sense in general. pantsbuild/pants
