According to its man page [1], pw_context_connect() sets errno on failure: Returns a Core on success or NULL with errno set on error.
It may be handy to see errno when figuring out why PipeWire failed to connect. That leaves us with just one possible path to reach 'fail_error' label which is then moved to that path and also its error message is adjusted slightly. 1: https://docs.pipewire.org/group__pw__core.html#ga5994e3a54e4ec718094ca02a1234815b Signed-off-by: Michal Privoznik <mpriv...@redhat.com> --- v2 of: https://mail.gnu.org/archive/html/qemu-devel/2024-09/msg03485.html diff to v1: - Dropped duplicated S-o-b line - Fixed typo on error message (s/PipeWite/PipeWire/) audio/pwaudio.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/audio/pwaudio.c b/audio/pwaudio.c index 3b14e04fbb..8e13b58286 100644 --- a/audio/pwaudio.c +++ b/audio/pwaudio.c @@ -769,13 +769,15 @@ qpw_audio_init(Audiodev *dev, Error **errp) pw->core = pw_context_connect(pw->context, NULL, 0); if (pw->core == NULL) { pw_thread_loop_unlock(pw->thread_loop); - goto fail_error; + error_setg_errno(errp, errno, "Failed to connect to PipeWire instance"); + goto fail; } if (pw_core_add_listener(pw->core, &pw->core_listener, &core_events, pw) < 0) { pw_thread_loop_unlock(pw->thread_loop); - goto fail_error; + error_setg(errp, "Failed to add PipeWire listener"); + goto fail; } if (wait_resync(pw) < 0) { pw_thread_loop_unlock(pw->thread_loop); @@ -785,8 +787,6 @@ qpw_audio_init(Audiodev *dev, Error **errp) return g_steal_pointer(&pw); -fail_error: - error_setg(errp, "Failed to initialize PW context"); fail: if (pw->thread_loop) { pw_thread_loop_stop(pw->thread_loop); -- 2.44.2
