From: Simon Marchi Date: Thu, 15 Apr 2021 13:07:31 +0000 (-0400) Subject: lttng list-triggers: handle all condition types X-Git-Tag: v2.13.0-rc1~37 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=19904669a9eb25cd4a0ccd3de82d3ac803dfe877;p=lttng-tools.git lttng list-triggers: handle all condition types At the moment, only the event-rule-matches condition is handled by the list-triggers commands. Change it to handle all existing condition types. Because these other condition types can't be created using the command-line interface, add a util program that creates and registers triggers for the purpose of the test. The test triggers with the event-rule-matches condition are kept as is, created using the command-line interface.
