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 - `ShaderRD` contained an `std::mutex`, which has been replaced by `Mutex`.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/mono/utils/mutex_utils.h | 67 ---------------------------------------- 1 file changed, 67 deletions(-) delete mode 100644 modules/mono/utils/mutex_utils.h (limited to 'modules/mono/utils') diff --git a/modules/mono/utils/mutex_utils.h b/modules/mono/utils/mutex_utils.h deleted file mode 100644 index bafd875395..0000000000 --- a/modules/mono/utils/mutex_utils.h +++ /dev/null @@ -1,67 +0,0 @@ -/*************************************************************************/ -/* mutex_utils.h */ -/*************************************************************************/ -/* This file is part of: */ -/* GODOT ENGINE */ -/* https://godotengine.org */ -/*************************************************************************/ -/* Copyright (c) 2007-2020 Juan Linietsky, Ariel Manzur. */ -/* Copyright (c) 2014-2020 Godot Engine contributors (cf.
