Ozkan Sezer a90f0400a5 os2: a _lot_ of coding style cleanup, sot that they match the SDL style.
also renamed the 'debug' macro to debug_os2: the former was dangerously
a common name.

the binary (dll) output is precisely the same as before.

Sam Lantinga abd5841850 Make some changes to SDL_SetThreadPriority to try and have SDL transparently handle more of the work.
1. Comment that SDL_SetThreadPriority will make any necessary system changes when applying priority.
2. Add a hint to override SDL's default behavior for scheduler policy.
3. Modify the pthreads SDL_SetThreadPriority so that instead of just using the current thread scheduler policy it will change it to a policy that should work best for the requested priority.
4. Add hint checks in SDL_SetThreadPriority so that  can be overridden if desired.
5. Modify the Linux SDL_SetThreadPriority so that in the case that policy, either by SDL defaults or from the hint, is a realtime policy it uses the realtime rtkit API.
6. Prior to calling rtkit on Linux make the necessary thread state changes that rtkit requires.  Currently this is done every time as it isn't expected that SDL_SetThreadPriority will be called repeatedly for a thread.

Ryan C. Gordon 46bb47cf04 thread: Put all important SDL_CreateThread internal data into SDL_Thread.
This avoids the need to malloc something extra, use a semaphore, etc, and
fixes Emscripten with pthreads support, which might not spin up a web worker
until after SDL_CreateThread returns and thus can't wait on a semaphore at
this point in any case.

Fixes Bugzilla .

Sam Lantinga bd5da73afd Fixed bug 4992 - UWP/WinRT does not set thread priority when using SDL_SetThreadPriority
Ethan Lee

Attached is a diff that I used to get SetThreadPriority working locally. I still have no idea what the minimum SDK version is since Microsoft never documented it, but it's worth pointing out that they're much more aggressive about using the latest VS and UWP SDK anyway (for example, an updated Xbox is no longer compatible with VS2017, and updates are required to have a network connection of any kind).

Sam Lantinga a1b8fa6071 TryLockMutex: Fix error handling for TryLockMutex
Christian Herzig

pthread_mutex_trylock() and by the way, pthread_mutex_lock() do not set errno.
Pthread-methods directly return error code as int. See related man-pages for
details.

Sam Lantinga 816a6e68e5 Added support for adjusting thread priorities using Linux RealtimeKit
Michael Sartain

This is a quick pass at adding Linux RealtimeKit thread priority support to SDL.

It allows me to bump the thread priority to high without root privileges or setting any caps, etc.

Sam Lantinga f9f45d0bf5 Fixed bug 4097 - Segmentation fault by SDL_CreateThreadWithStackSize
Dongsun Kim

Normal case
1. [thread 1] SDL_CreateThreadWithStackSize calls SDL_SYS_CreateThread.
2. [thread 1] If successful, it calls SDL_SemWait.
3. [thread 2] SDL_RunThread calls SDL_SYS_SetupThread, SDL_ThreadID, SDL_SemPost.
4. [thread 1] SDL_CreateThreadWithStackSize calls SDL_DestroySemaphore, SDL_free.

Crash case (Segmentation fault)
1. [thread 1] SDL_CreateThreadWithStackSize calls SDL_SYS_CreateThread.
2. [thread 1] If successful, it calls SDL_SemWait.
--> Error return due to SIGNAL(SYSTEM or Real Time) at sem_wait(pthread).
3. [thread 1] SDL_CreateThreadWithStackSize calls SDL_DestroySemaphore, SDL_free.
4. [thread 2] SDL_RunThread calls SDL_SYS_SetupThread, SDL_ThreadID, SDL_SemPost.
--> Segmentation fault at strlen or sem_post.

Ryan C. Gordon 75a58303a0 pthread: fix error code checks (thanks, Andreas!).
Most pthread functions return 0 on success and non-zero on error, but those
errors might be positive or negative, so checking for return values in the
Unix style, where errors are less than zero, is a bug.

Sam Lantinga 7229397c0c Fixed bug 3258 - SDL_TryLockMutex blocks for pthreads with FAKE_RECURSIVE_MUTEX
Ian Abbott

I just spotted what I think is a bug in "src/thread/pthread/SDL_sysmutex.c" in the SDL_TryLockMutex function when FAKE_RECURSIVE_MUTEX is defined (for an implementation of Pthreads with no recursive mutex support).  It calls pthread_mutex_lock instead of pthread_mutex_trylock, so it will block until the mutex is available instead of returning SDL_MUTEX_TIMEDOUT if it cannot lock the mutex immediately.

Ryan C. Gordon 6d661cab7b windows: Change the default on SDL_HINT_WINDOWS_DISABLE_THREAD_NAMING.
It's easier for Visual Studio users that want this information to turn it on
or live without it, than it is to explain why every debugger that isn't Visual
Studio crashes out here. Eventually SetThreadDescription() will be the thing
everyone uses anyhow.

Fixes Bugzilla .
