From 7231e59fecf19de0077f8eae3baed952155fa62b Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Mon, 14 Aug 2023 08:20:52 -0700 Subject: modules/rkt: wire up pipe_dtor to stop leaking rkt_pipe_t On shutdown til_stream_untap_owner() will call into the pipe_dtor hook if set. So until now this was just (harmlessly) leaking the rkt_pipe_t allocated by the pipe_ctor hook on the road to process exit. But in the interests of silencing ASAN about leaks on graceful exit, I'm tying up these loose ends. This dtor will also be utilized for performing a FORGET_TRACK via Rocket once that's a thing. While here I also got rid of the pipe_dtor return value, as it's unused with no clear potential purpose (for now). --- src/modules/rkt/rkt.c | 17 +++++++++++++++-- 1 file changed, 15 insertions(+), 2 deletions(-) (limited to 'src/modules') diff --git a/src/modules/rkt/rkt.c b/src/modules/rkt/rkt.c index d5c42d5..3a48606 100644 --- a/src/modules/rkt/rkt.c +++ b/src/modules/rkt/rkt.c @@ -134,7 +134,7 @@ typedef struct rkt_pipe_t { } rkt_pipe_t; -int rkt_stream_pipe_ctor(void *context, til_stream_t *stream, const void *owner, const void *owner_foo, const char *parent_path, uint32_t parent_hash, const til_tap_t *tap, const void **res_owner, const void **res_owner_foo, const til_tap_t **res_driving_tap) +static int rkt_stream_pipe_ctor(void *context, til_stream_t *stream, const void *owner, const void *owner_foo, const char *parent_path, uint32_t parent_hash, const til_tap_t *tap, const void **res_owner, const void **res_owner_foo, const til_tap_t **res_driving_tap) { rkt_context_t *ctxt = context; rkt_pipe_t *rkt_pipe; @@ -165,10 +165,23 @@ int rkt_stream_pipe_ctor(void *context, til_stream_t *stream, const void *owner, return 1; } +static void rkt_stream_pipe_dtor(void *context, til_stream_t *stream, const void *owner, const void *owner_foo, const char *parent_path, const til_tap_t *tap) +{ + rkt_context_t *ctxt = context; + + assert(stream); + assert(tap); + + if (owner != ctxt) + return; /* not interesting to us */ + + free((void *)owner_foo); +} + static const til_stream_hooks_t rkt_stream_hooks = { .pipe_ctor = rkt_stream_pipe_ctor, - /* .pipe_dtor unneeded */ + .pipe_dtor = rkt_stream_pipe_dtor, }; -- cgit v1.2.3
