From: Jérémie Galarneau Date: Fri, 9 Feb 2018 21:40:39 +0000 (-0500) Subject: Tests: refuse to run test suite if lttng processes are present X-Git-Tag: v2.9.8~18 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=875960df8c182d724db6921eb507847bd9b3919e;p=lttng-tools.git Tests: refuse to run test suite if lttng processes are present The test suite often fails because of unclean environments where stale LTTng processes are left running. Since the test suite assumes that no LTTng process (daemons and test applications) are running, it makes sense to force the user to kill all those processes before running the test suite. The warn_processes.sh script now prints an error and returns 1 to indicate an early failure to the test harness. It is possible to circumvent this check by invoking the tests manually or by removing the "exit 1" from the warn_processes.sh script if there is a need to have persistent processes across the execution of the test suite.
