commit 5fbd195918b4f5ad73130547c2ca58fd69baded0 Author: Nick Mathewson nickm@torproject.org Date: Mon Jun 20 11:15:47 2016 -0400
Coverage hack for test_switch_id.sh
This hack provides a way to make sure we can see coverage from test-switch-id. If you set OVERRIDE_GCDA_PERMISSIONS_HACK, we temporarily make the .gcda files mode 0666 before we run the test scripts, and then we set them to 0644 again afterwards.
That's necessary because the test_switch_id.sh script does a setuid() to 'nobody' part way through, and drops the ability to change its mind back. --- src/test/test_switch_id.sh | 7 +++++++ 1 file changed, 7 insertions(+)
