Hi, why is pants starting and cancelling stuff. I only see this on our CI platform (aws codebuild), not locally though

at the end it is able to run tests successfully though.
there is no caching enabled
Similar behavior with 
lint

sadly can't access it since these are running inside docker container on aws.
p
it is recommended to upload it as a build artifact for CI runs. see: https://www.pantsbuild.org/docs/using-pants-in-ci#tip-store-pants-logs-as-artifacts

Usually cancellation happens when something is satisfied from remote cache
which you don't have set up anyway?

Given that things keep restarting, I suspect that it is indeed some thing with pants_ignore. Some file is being generated that is causing pants to think it needs to restart. For example, a .PYC file -- that should already be filtered out by pants, but something like that
h
Yeah, good call, that sounds likely
Well, but it would have to be one of the ingredients to 
pytest.pex
, and the only one is 
pytest_default_lockfile.txt
Could that be being modified within the CI run somehow?
