I am surprised to see what ` pants dependencies` does when dependency inference is disabled and enabled thread

on <https github com pantsbuild example python> ```cp helloworld translator translator test py helloworld translator translator another test py ``` ```$ pants dependencies helloworld translator translator test py reqs pytest helloworld translator translator py lib $ PANTS PYTHON INFER IMPORTS=False pants dependencies helloworld translator translator test py helloworld translator translator another test py tests``` Why does Pants report `translator another test py` to be a dependency of `helloworld translator translator test py` It s clearly not ```$ pants paths to=helloworld translator translator test py from=helloworld translator translator another test py ``` It must have something to do with the fact that they are part of the same target but I can t find the reasoning behind this behavior when dependency inference is disabled

that is with dep inference off there s an implicit assumption that all files in the same module have a dependency on each other

wow

I found <https github com pantsbuild pants pull 12906>

okay this may make sense for `python sources` but for `python tests` confused

True as tests are executed one by one probably doesn t make sense there cc < hundreds father 404> thoughts

hm yeah probably doesn t make sense for tests

hundreds-father-404 · Answer

but generally it d be better to have an option to disable this it should be legal to have your own dep inference implementation and ignore our builtin one

hundreds-father-404 · Answer

this behavior destroys effective caching even tho it s a good default if you have no dep inference at all

gt but generally it d be better to have an option to disable this advanced option on python infer In fact I thought we added it but couldn t find it Someone wanted it 2 months ago

amazing thank you for giving it a thought Shall I file a GH issue with the motivation and command examples to illustrate the problem ```$ pants changed since=HEAD changed dependees=direct filter target type=python test list``` The use case is that if there have been changes to a test module this command would list all Python test modules in the same `python tests` target which is unnecessary

gt that is with dep inference off there s an implicit assumption that all files in the same module have a dependency on each other Is it all files in the same module or all files in the same target generator

hundreds-father-404 · Answer

same target generator

point up yep I was inaccurate in that statement
