From 9f9f9eaa096e6be8c1613014868e919d6991b188 Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Sun, 24 Apr 2022 19:24:47 -0700 Subject: *: s/void */til_setup_t */ This brings something resembling an actual type to the private objects returrned in *res_setup. Internally libtil/rototiller wants this to be a til_setup_t, and it's up to the private users of what's returned in *res_setup to embed this appropriately and either use container_of() or casting when simply embedded at the start to go between til_setup_t and their private containing struct. Everywhere *res_setup was previously allocated using calloc() is now using til_setup_new() with a free_func, which til_setup_new() will initialize appropriately. There's still some remaining work to do with the supplied free_func in some modules, where free() isn't quite appropriate. Setup freeing isn't actually being performed yet, but this sets the foundation for that to happen in a subsequent commit that cleans up the setup leaks. Many modules use a static default setup for when no setup has been provided. In those cases, the free_func would be NULL, which til_setup_new() refuses to do. When setup freeing actually starts happening, it'll simply skip freeing when til_setup_t.free_func is NULL. --- src/modules/compose/compose.c | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) (limited to 'src/modules/compose') diff --git a/src/modules/compose/compose.c b/src/modules/compose/compose.c index 180df44..0fa1204 100644 --- a/src/modules/compose/compose.c +++ b/src/modules/compose/compose.c @@ -37,14 +37,15 @@ typedef struct compose_context_t { } compose_context_t; typedef struct compose_setup_t { + til_setup_t til_setup; size_t n_layers; char *layers[]; } compose_setup_t; -static void * compose_create_context(unsigned ticks, unsigned num_cpus, void *setup); +static void * compose_create_context(unsigned ticks, unsigned num_cpus, til_setup_t *setup); static void compose_destroy_context(void *context); static void compose_prepare_frame(void *context, unsigned ticks, unsigned n_cpus, til_fb_fragment_t *fragment, til_fragmenter_t *res_fragmenter); -static int compose_setup(const til_settings_t *settings, til_setting_t **res_setting, const til_setting_desc_t **res_desc, void **res_setup); +static int compose_setup(const til_settings_t *settings, til_setting_t **res_setting, const til_setting_desc_t **res_desc, til_setup_t **res_setup); static compose_setup_t compose_default_setup = { .layers = { "drizzle", "stars", "spiro", "plato", NULL }, @@ -61,13 +62,13 @@ til_module_t compose_module = { }; -static void * compose_create_context(unsigned ticks, unsigned num_cpus, void *setup) +static void * compose_create_context(unsigned ticks, unsigned num_cpus, til_setup_t *setup) { compose_context_t *ctxt; size_t n; if (!setup) - setup = &compose_default_setup; + setup = &compose_default_setup.til_setup; for (n = 0; ((compose_setup_t *)setup)->layers[n]; n++); @@ -79,7 +80,7 @@ static void * compose_create_context(unsigned ticks, unsigned num_cpus, void *se for (int i = 0; i < n; i++) { const til_module_t *layer_module; - void *layer_setup = NULL; + til_setup_t *layer_setup = NULL; layer_module = til_lookup_module(((compose_setup_t *)setup)->layers[i]); (void) til_module_randomize_setup(layer_module, &layer_setup, NULL); @@ -117,7 +118,7 @@ static void compose_prepare_frame(void *context, unsigned ticks, unsigned n_cpus } -static int compose_setup(const til_settings_t *settings, til_setting_t **res_setting, const til_setting_desc_t **res_desc, void **res_setup) +static int compose_setup(const til_settings_t *settings, til_setting_t **res_setting, const til_setting_desc_t **res_desc, til_setup_t **res_setup) { const char *layers; int r; @@ -137,7 +138,7 @@ static int compose_setup(const til_settings_t *settings, til_setting_t **res_set /* turn layers colon-separated list into a null-terminated array of strings */ if (res_setup) { - compose_setup_t *setup = NULL; + compose_setup_t *setup; const til_module_t **modules; size_t n_modules; char *toklayers, *layer; @@ -153,6 +154,10 @@ static int compose_setup(const til_settings_t *settings, til_setting_t **res_set if (!layer) return -EINVAL; + setup = til_setup_new(sizeof(*setup), (void(*)(til_setup_t *))free); + if (!setup) + return -ENOMEM; + do { compose_setup_t *new; size_t i; @@ -184,7 +189,7 @@ static int compose_setup(const til_settings_t *settings, til_setting_t **res_set setup = new; } while (layer = strtok(NULL, ":")); - *res_setup = setup; + *res_setup = &setup->til_setup; } return 0; -- cgit v1.2.1
