From 52c66b47664d47154b2c8368e32beef27d4b2d03 Mon Sep 17 00:00:00 2001 From: Tanu Kaskinen <ext-tanu.kaskinen@nokia.com> Date: Thu, 3 Dec 2009 13:22:05 +0200 Subject: [PATCH] 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. --- src/pulse/context.c | 12 ++++++------ src/pulse/internal.h | 3 +-- src/pulse/stream.c | 20 ++++++++++---------- 3 files changed, 17 insertions(+), 18 deletions(-) diff --git a/src/pulse/context.c b/src/pulse/context.c index c83230d..91f4817 100644 --- a/src/pulse/context.c +++ b/src/pulse/context.c @@ -63,7 +63,7 @@ #include <pulsecore/native-common.h> #include <pulsecore/pdispatch.h> #include <pulsecore/pstream.h> -#include <pulsecore/dynarray.h> +#include <pulsecore/hashmap.h> #include <pulsecore/socket-client.h> #include <pulsecore/pstream-util.h> #include <pulsecore/core-rtclock.h> @@ -157,8 +157,8 @@ pa_context *pa_context_new_with_proplist(pa_mainloop_api *mainloop, const char * c->system_bus = c->session_bus = NULL; #endif c->mainloop = mainloop; - 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); @@ -252,9 +252,9 @@ 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); @@ -361,7 +361,7 @@ 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 c3ebf74..ab702b9 100644 --- a/src/pulse/internal.h +++ b/src/pulse/internal.h @@ -34,7 +34,6 @@ #include <pulsecore/socket-client.h> #include <pulsecore/pstream.h> #include <pulsecore/pdispatch.h> -#include <pulsecore/dynarray.h> #include <pulsecore/llist.h> #include <pulsecore/native-common.h> #include <pulsecore/strlist.h> @@ -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 daeb53a..ab8f8f4 100644 --- a/src/pulse/stream.c +++ b/src/pulse/stream.c @@ -201,7 +201,7 @@ 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) ?
