The `TimeoutExpired` exception is used in multiple locations throughout the Python tests. However, it needs to be used as `subprocess.TimeoutExpired` given that it is only defined in that module. Signed-off-by: Antoine Busque <[email protected]>

When running
$ lttng add-trigger --condition on-event -u ust_tests_demo2:loop --capture intfield --action notify
I get the leaks pasted below. It seems like filter_parser_ctx_free
doesn't free everything in filter_parser_ctx. Add what's missing.
Re-order the frees so that they are in the same order as the members of
the struct, just because it's easier to follow and make sure we didn't
forget anything.

Observed issue ============== A dead lock is observed during the start-stop test suite for triggers. Cause ===== A start session action is executed by the action executor, the `cmd_start_trace` function is called and effectively holds the `session_list_lock.`. During `cmd_start_trace` a call to `notification_thread_command_add_channel` is performed to inform the notification thread of the new channel presence. At the same time, a tracer event notification is received by the notification thread. The actions are queued up and the sample of the session id take place and a call to `session_lock_list` is performed and blocks on the lock operation. The notification thread wait on the `session_list_lock` and the `session_list_lock` holder, the action executor, waits on the completion of a command the be run by the notification thread: deadlock. The backtrace: Thread 6 (Thread 0x7f831c8a6700 (LWP 3046458)): #0 syscall () at ../sysdeps/unix/sysv/linux/x86_64/syscall.S:38 #1 0x000000000053b852 in futex (uaddr=0x7f831c8a45e0, op=0, val=0,

0x00007f8320a87293 in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:95 Solution ======== Instead of using session_find_by_name() which requires the `session_list_lock`, we introduce `sample_session_id_by_name` that uses a urcu backed data structure. This allows the sampling of the session id without holding the session list lock. We accept the small window where a session object is still accessible but concretely not valid since the actual execution context will be validated at the moment of execution. The execution side already handles the possibility that the session is removed at that point or is not the same session. The execution side acquires the session_list_lock for validation. Known drawbacks ========= None Signed-off-by: Jonathan Rajotte <[email protected]> Signed-off-by: Jérémie Galarneau <[email protected]> Change-Id: I5ad2c57acc0d03d2814dda59f8ecf2d831fd961e

When running
$ lttng add-trigger --condition on-event -u ust_tests_demo2:loop --capture intfield --action notify
I get the leaks pasted below. It seems like filter_parser_ctx_free
doesn't free everything in filter_parser_ctx. Add what's missing.
Re-order the frees so that they are in the same order as the members of
the struct, just because it's easier to follow and make sure we didn't
forget anything.

When running
$ lttng add-trigger --condition on-event -u ust_tests_demo2:loop --capture intfield --action notify
I get the leaks pasted below. It seems like filter_parser_ctx_free
doesn't free everything in filter_parser_ctx. Add what's missing.
Re-order the frees so that they are in the same order as the members of
the struct, just because it's easier to follow and make sure we didn't
forget anything.
