Currently a couple of dynevent tests will always report UNSUPPORTED and
not run, even when support is actually present.
In commit:
95c104c378dc7d4c ("tracing: Auto generate event name when creating a group of events")
The README text for synthetic events was changed from:
"e[:[<group>/]<event>] <attached-group>.<attached-event> [<args>]\n"
To:
"e[:[<group>/][<event>]] <attached-group>.<attached-event> [<args>]\n"
... but the dynevent selftests were not updated accodingly, and still
search for the old text in their "requires" lines. Consequently, they
fail to match the new text, and the tests report the feature is
UNSUPPORTED.
For example:
| # ./ftracetest -vv test.d/dynevent/test_duplicates.tc
| === Ftrace unit tests ===
| [1] Generic dynamic event - check if duplicate events are caughtRequired feature pattern "e[:[<group>/]<event>] <attached-group>.<attached-event> [<args>]" is not in README.
| [UNSUPPORTED]
|
|
| # of passed: 0
| # of failed: 0
| # of unresolved: 0
| # of untested: 0
| # of unsupported: 1
| # of xfailed: 0
| # of undefined(test bug): 0
Update the patterns to match, allowing the tests to run:
| # ./ftracetest -vv test.d/dynevent/test_duplicates.tc
| === Ftrace unit tests ===
| [1] Generic dynamic event - check if duplicate events are caught
| [PASS]
|
|
| # of passed: 1
| # of failed: 0
| # of unresolved: 0
| # of untested: 0
| # of unsupported: 0
| # of xfailed: 0
| # of undefined(test bug): 0

Shuah, can you take Sven's patch through your tree?
Thanks,
