Bug 35416 – new-run-webkit-tests: split Port.check_sys_deps() into two calls

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Dirk Pranke]

Currently there is a circular dependency between Port.check_sys_deps() and Port.start_helper() - you need to start the helper before check_sys_deps() will pass on chromium windows, but that gives you no way to check if the helper has been built (since that would be done in check_sys_deps() ).

Do we need a --nocheck-build flag? Unlike checking system dependencies, if we can't find DRT/TestShell, then this script really can't do anything useful.

Documenting these arguments would help. I'm not really sure what exe_str and override_str are.Now that I look at how it's used, names like "exe_description" and "override_description" might be a bit more clear.

I know you're not adding it in this change, but do we need --nostart-helper? When would you ever want to run the tests without the start helper?

(In reply to comment #2)

I could see that maybe --nocheck-build and --nostart-helper are too esoteric (they are useful if you want to run the 'passing-*' platforms, which stub out TestShell and don't need the layout_test_helper.

I will update the arg names.

If possible avoid the comparisons to 0 (several places have "!= 0").
