Subject: misc/build_helpers/run_trial.py: allow the module argument to specify a leaf module... 
X-Git-Url: https://git.rkrishnan.org/pf/content/en/%3C?a=commitdiff_plain;h=41e96b3e5a61940113a562b7046d3aa6827e25f5;p=tahoe-lafs%2Ftahoe-lafs.git

misc/build_helpers/run_trial.py: allow the module argument to specify a leaf module rather than a directory. This fixes false positive wrong-source errors in the test-from-prefixdir step when we test only allmydata.test.test_runner.
