From 18fbdbb456c07a56b358bea2e392765fbcbb3283 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pedro=20J=2E=20Est=C3=A9banez?= Date: Wed, 26 Feb 2020 11:28:13 +0100 Subject: Reimplement Mutex with C++'s Main: - It's now implemented thanks to ``. No more platform-specific implementations. - `BinaryMutex` (non-recursive) is added, as an alternative for special cases. - Doesn't need allocation/deallocation anymore. It can live in the stack and be part of other classes. - Because of that, it's methods are now `const` and the inner mutex is `mutable` so it can be easily used in `const` contexts. - A no-op implementation is provided if `NO_THREADS` is defined. No more need to add `#ifdef NO_THREADS` just for this. - `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`. - Thread-safe utilities are therefore simpler now. Misc.: - `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same. - Every case of lock, do-something, unlock is replaced by `MutexLock` (complex cases where it's not straightfoward are kept as as explicit lock and unlock). - `ShaderRD` contained an `std::mutex`, which has been replaced by `Mutex`. --- modules/gdnative/nativescript/nativescript.h | 12 +++--------- 1 file changed, 3 insertions(+), 9 deletions(-) (limited to 'modules/gdnative/nativescript/nativescript.h') diff --git a/modules/gdnative/nativescript/nativescript.h b/modules/gdnative/nativescript/nativescript.h index 609ffa2bd4..04670b952b 100644 --- a/modules/gdnative/nativescript/nativescript.h +++ b/modules/gdnative/nativescript/nativescript.h @@ -35,6 +35,7 @@ #include "core/io/resource_saver.h" #include "core/oa_hash_map.h" #include "core/ordered_hash_map.h" +#include "core/os/mutex.h" #include "core/os/thread_safe.h" #include "core/resource.h" #include "core/script_language.h" @@ -44,10 +45,6 @@ #include "modules/gdnative/gdnative.h" #include -#ifndef NO_THREADS -#include "core/os/mutex.h" -#endif - struct NativeScriptDesc { struct Method { @@ -127,9 +124,7 @@ class NativeScript : public Script { String script_class_name; String script_class_icon_path; -#ifndef NO_THREADS - Mutex *owners_lock; -#endif + Mutex owners_lock; Set instance_owners; protected: @@ -266,9 +261,8 @@ private: void _unload_stuff(bool p_reload = false); + Mutex mutex; #ifndef NO_THREADS - Mutex *mutex; - Set > libs_to_init; Set scripts_to_register; volatile bool has_objects_to_register; // so that we don't lock mutex every frame - it's rarely needed -- cgit v1.2.3
