submodules are only ignore if `files_changed_only` is True about cpp-linter-action HOT 9 CLOSED

I might have to use a matrix in the CI to test various versions of python with various versions of clang-tools on various OSs... My new database test is failing in CI, but it passes fine locally.

The test coverage is already very high 👍

@2bndy5 I have created a org secret with a new codecov token and also removed codecov token for cpp-linter/clang-tools-pip, then rerun the test action of clang-tools-pip, it still works.

When --files-changed-only=ture, it should ignore submodules.
When --files-changed-only=false, analyze any source files in the repo including submodules.

So the current behavior of --files-changed-only=false is not expected?

I'm wondering if we should change files-changed-only default value to true. I guess users only care about modified files, not all source files.

This was not my original intention. It doesn't make sense (to me) for a linter to be concerned with external sources. That's why in the README, I noted the ignore option can be used to explicitly include submodules (just not hidden folders that begin with a . like .github).

I have no objections to this. I think this was the original default until we started encouraging users to have a actions/checkout step. I also expect most users only want the file changes analyzed. Personally, I've been using this action to check all sources in my projects (for completeness because I itch for that 💯 ). I haven't been using clang-tidy for anything lately (but that may change in the future).

I'm almost ready to draft a PR... There's a lot of changes, so the description will be wordy. I'd like to learn a bit more about pytest (& plugins) to optimize the unit tests I've written.

I agree we should only analyze any source files and ignore submodules when --files-changed-only=false

No worries, take your time. I'm also learning about pytest to refactor my bad smell unit tests :(

It also failed in my local environment.

It failed locally for you because it couldn't download the source files from the commit that I'm using in the test.

The test that failed for you was the lines-changed-only test. The one that failed in CI was the database test.

I've been playing with test coverage to see what else needs to be tested. So far I'm (locally) getting 94% coverage if I exclude any functions that directly use the REST API for thread comments:

I also configured coverage.py to ignore code specific to type checking and anything related to using rich as a logging extension, thus __init__.py is 100% covered. cpp_linter/thread_comments.py is also ignored because we would need a real CI event to test that code.

@shenxianpeng I see you've already created a codecov token for cpp-linter/clang-tools-pip. Can you create a org secret with a new codecov token, so we can use it for multiple repos? Or does the token have to specific to a project?

ps - Ensuring the best coverage has caused further improvements to the code base.
