Pants lint goal with regex-lint linter ignores changes to the configuration file unless .pids is nuked

[alexey-tereshenkov-oxb]

Describe the bug

When running

$ ./pants lint '**'

using a configuration file loaded with [regex-lint].config in the pants.toml file, changes in the configuration file are ignored unless the .pids directory is removed before re-running the command:

$ rm -r .pids; ./pants lint '**'

Creating a new configuration file and updating the [regex-lint].config in the pants.toml file does not help either.

I expect Pants to re-load the modified configuration out of the configuration file.

Pants version
Pants 2.10, 2.11

OS
MacOS

I assume that you are using an @file option with the config? Unfortunately, that is subject to #10360. Will close as a dupe, but please reopen if that's not the case.

Note also that it should be possible to define the config directly in pants.toml (using toml syntax), rather than via an @file, although I haven't seen anyone try it.

Oh thanks @stuhood -- sorry my search for existing issues around it failed... yep, I use the @file syntax. I'll experiment on using the regex-linter in CI -- perhaps this is going to be fine given a build starts in a fresh container, so .pids won't be preserved.
