This action assumes that GAP coverage has been created by the profiling package

[wilfwilson]

And it fails with an error if that is not the case.

This is because the following directory does not exist, and looping over fail gives an error:

process-coverage/action.yml

Lines 23 to 25 in e94c556

	d := Directory("${COVDIR-coverage}");;
	covs := [];;
	for f in DirectoryContents(d) do

This means that this action cannot be used by the profiling package itself, even though the following line of this action would be useful for the profiling package:

process-coverage/action.yml

Line 39 in e94c556

find . -type f -name '*.gcno' -exec gcov -pb {} +

Resolution

• Either there should be separate actions for processing GAP code coverage and for processing C/C++ coverage
• Or this action should gracefully handle the situation where one kind of coverage exists, but not the other kind.
