X-Git-Tag: 1.0_branch~1112 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4c793cfc76360676b3881d7943b49adf892594d2;p=profile%2Fivi%2Fpulseaudio.git libpulse: Store pa_stream pointers to hashmaps instead of dynarrays. Since the stream identifiers (channels) are monotonically growing integer, it isn't a good idea to use them as index to a dynamic array, because the array will grow all the time. This is not a problem with client connections that don't create many streams, but, for example, long-running clients that use libcanberra for playing event sounds, this means that the client connection effectively leaks memory. --- diff --git a/src/pulse/context.c b/src/pulse/context.c index e33143d..0018492 100644 --- a/src/pulse/context.c +++ b/src/pulse/context.c @@ -63,7 +63,7 @@ #include #include #include -#include +#include #include #include #include @@ -160,8 +160,8 @@ pa_context *pa_context_new_with_proplist(pa_mainloop_api *mainloop, const char * c->client = NULL; c->pstream = NULL; c->pdispatch = NULL; - c->playback_streams = pa_dynarray_new(); - c->record_streams = pa_dynarray_new(); + c->playback_streams = pa_hashmap_new(pa_idxset_trivial_hash_func, pa_idxset_trivial_compare_func); + c->record_streams = pa_hashmap_new(pa_idxset_trivial_hash_func, pa_idxset_trivial_compare_func); c->client_index = PA_INVALID_INDEX; c->use_rtclock = pa_mainloop_is_our_api(mainloop); @@ -266,9 +266,9 @@ static void context_free(pa_context *c) { #endif if (c->record_streams) - pa_dynarray_free(c->record_streams, NULL, NULL); + pa_hashmap_free(c->record_streams, NULL, NULL); if (c->playback_streams) - pa_dynarray_free(c->playback_streams, NULL, NULL); + pa_hashmap_free(c->playback_streams, NULL, NULL); if (c->mempool) pa_mempool_free(c->mempool); @@ -375,7 +375,7 @@ static void pstream_memblock_callback(pa_pstream *p, uint32_t channel, int64_t o pa_context_ref(c); - if ((s = pa_dynarray_get(c->record_streams, channel))) { + if ((s = pa_hashmap_get(c->record_streams, PA_UINT32_TO_PTR(channel)))) { if (chunk->memblock) { pa_memblockq_seek(s->record_memblockq, offset, seek, TRUE); diff --git a/src/pulse/internal.h b/src/pulse/internal.h index b371bfc..9545d50 100644 --- a/src/pulse/internal.h +++ b/src/pulse/internal.h @@ -34,7 +34,6 @@ #include #include #include -#include #include #include #include @@ -66,7 +65,7 @@ struct pa_context { pa_pstream *pstream; pa_pdispatch *pdispatch; - pa_dynarray *record_streams, *playback_streams; + pa_hashmap *record_streams, *playback_streams; PA_LLIST_HEAD(pa_stream, streams); PA_LLIST_HEAD(pa_operation, operations); diff --git a/src/pulse/stream.c b/src/pulse/stream.c index 4dea567..4081256 100644 --- a/src/pulse/stream.c +++ b/src/pulse/stream.c @@ -199,7 +199,7 @@ static void stream_unlink(pa_stream *s) { pa_pdispatch_unregister_reply(s->context->pdispatch, s); if (s->channel_valid) { - pa_dynarray_put((s->direction == PA_STREAM_PLAYBACK) ?
