From 754f26a97c816781e80500d98f2515ae97836145 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Wed, 14 Sep 2011 21:46:41 +0200 Subject: input_stream: non-blocking I/O Add GMutex, GCond attributes which will be used by callers to conditionally wait on the stream. Remove the (now-useless) plugin method buffer(), wait on GCond instead. Lock the input_stream before each method call. Do the same with the playlist plugins. --- src/archive/bz2_archive_plugin.c | 13 ++++++++++--- src/archive/iso9660_archive_plugin.c | 8 +++++--- src/archive/zzip_archive_plugin.c | 7 +++++-- 3 files changed, 20 insertions(+), 8 deletions(-) (limited to 'src/archive') diff --git a/src/archive/bz2_archive_plugin.c b/src/archive/bz2_archive_plugin.c index 90418720e..303f22136 100644 --- a/src/archive/bz2_archive_plugin.c +++ b/src/archive/bz2_archive_plugin.c @@ -114,7 +114,11 @@ bz2_open(const char *pathname, GError **error_r) refcount_init(&context->ref); //open archive - context->istream = input_stream_open(pathname, error_r); + static GStaticMutex mutex = G_STATIC_MUTEX_INIT; + context->istream = input_stream_open(pathname, + g_static_mutex_get_mutex(&mutex), + NULL, + error_r); if (context->istream == NULL) { g_free(context); return NULL; @@ -169,12 +173,15 @@ bz2_close(struct archive_file *file) /* single archive handling */ static struct input_stream * -bz2_open_stream(struct archive_file *file, const char *path, GError **error_r) +bz2_open_stream(struct archive_file *file, const char *path, + GMutex *mutex, GCond *cond, + GError **error_r) { struct bz2_archive_file *context = (struct bz2_archive_file *) file; struct bz2_input_stream *bis = g_new(struct bz2_input_stream, 1); - input_stream_init(&bis->base, &bz2_inputplugin, path); + input_stream_init(&bis->base, &bz2_inputplugin, path, + mutex, cond); bis->archive = context; diff --git a/src/archive/iso9660_archive_plugin.c b/src/archive/iso9660_archive_plugin.c index da55feca2..bb6cb9588 100644 --- a/src/archive/iso9660_archive_plugin.c +++ b/src/archive/iso9660_archive_plugin.c @@ -173,15 +173,17 @@ struct iso9660_input_stream { }; static struct input_stream * -iso9660_archive_open_stream(struct archive_file *file, - const char *pathname, GError **error_r) +iso9660_archive_open_stream(struct archive_file *file, const char *pathname, + GMutex *mutex, GCond *cond, + GError **error_r) { struct iso9660_archive_file *context = (struct iso9660_archive_file *)file; struct iso9660_input_stream *iis; iis = g_new(struct iso9660_input_stream, 1); - input_stream_init(&iis->base, &iso9660_input_plugin, pathname); + input_stream_init(&iis->base, &iso9660_input_plugin, pathname, + mutex, cond); iis->archive = context; iis->statbuf = iso9660_ifs_stat_translate(context->iso, pathname); diff --git a/src/archive/zzip_archive_plugin.c b/src/archive/zzip_archive_plugin.c index 829fb6dd1..ad96b5f89 100644 --- a/src/archive/zzip_archive_plugin.c +++ b/src/archive/zzip_archive_plugin.c @@ -135,14 +135,17 @@ struct zzip_input_stream { static struct input_stream * zzip_archive_open_stream(struct archive_file *file, - const char *pathname, GError **error_r) + const char *pathname, + GMutex *mutex, GCond *cond, + GError **error_r) { struct zzip_archive *context = (struct zzip_archive *) file; struct zzip_input_stream *zis; ZZIP_STAT z_stat; zis = g_new(struct zzip_input_stream, 1); - input_stream_init(&zis->base, &zzip_input_plugin, pathname); + input_stream_init(&zis->base, &zzip_input_plugin, pathname, + mutex, cond); zis->archive = context; zis->file = zzip_file_open(context->dir, pathname, 0); -- cgit v1.2.3
