1d2d5753b9 [*] Linux: possible regressions in 57c5515173. Fixes read while transaction is signaled loops 2024-08-06 05:15:33 +01:00
1b240143c4 [*] POSIX: AuProcesses mustn't allocate (sorta) while in a COW address space (including accessing bad CRT apis) 2024-08-06 03:13:53 +01:00
57c5515173 [*] Linux: Harden recursive IO scheduling 2024-08-05 19:44:54 +01:00
55cac676f5 [+] AuLoop::NewSemaphoreEx with max count option for in-process (not ipc) limiting the total wakes.
This is required for Xbox, Xbox 360, and Win32 emulators deriving a mutex via a the NT semaphore primitive instead of the builtin binary semaphore (event) and mutex.

7cc41f1359 [*] Fix: axboe is a piss baby retard who cant even write a thread safe ring buffer
This is the dude tasked with managing Linshits IO stack, including the fundamentally flawed muh zero-syscall pissring (#a), the fucked io_submit apis that never worked properly (incl io_cancel that spuriously returns EINVAL despite all magics matching); the retard who stuck to Linus's idea that MUH O_DIRECT IS LE EVIL YOU MUST USE MY CACHES REEE REEE (#b); and the retard who got indirectly called out by Linus as being apart of the database maintainers who Linus didn't/doesnt like and who wanted these APIs in the first place (#c).

 #a
 This dumb cunt can't even write a ring buffer. He thinks the solution to everything is spawn a thread, like the glibc and libuv retards.
 He seems to think a ring buffer also magically hooks into a thread scheduler, and something something, orange lingo, muh zero syscall overhead as if the kernel should be/is constantly checking every thread for an arbitrary amount of IO ring buffers.

 #b
"The whole notion of "direct IO" is totally braindamaged. Just say no.

	This is your brain: O
	This is your brain on O_DIRECT: .

	Any questions?

I should have fought back harder. There really is no valid reason for EVER
using O_DIRECT. You need a buffer whatever IO you do, and it might as well
be the page cache. There are better ways to control the page cache than
play games and think that a page cache isn't necessary.

So don't use O_DIRECT."

"AIO is a horrible ad-hoc design, with the main excuse being "other, less gifted people, made that design, and we are implementing it for compatibility because database people - who seldom have any shred of taste - actually use it". But AIO was always really really ugly."

And that's not to mention Google and NodeJS has disabled the usage of his pissring implementation because of shit like this. His shit code has been and will continue to be a security risk. I can't blame them. This retard mustn't be trusted with so much as an 8 year olds lemonade stand.

5947e6a2c3 [*/+] Added internal AuLoop::WaitMultipleOrObjects function for POSIX Issue4+ users, excluding the BSDs, to optimize AuLoop::WaitForMultipleObject users. (Win32 and Xbox emulators).
This mitigates the epoll allocation / release under Linux.

5cafefae5d [*] LSLocalSemaphore bug fix for scriptability. (TODO: reimpl like the event?)
[*] Fix: IO objects not using the explicit slow sync primitives.
Dunno how these werent refactored; then again, i never properly got around to finishing the factories for fast/slow io objects. In addition, some of these arent even accessed by the ILoopSource interface, so it's not as critical of a failure.

035d822ec1 [*] Explicit memory order access barrier when reading WOA_SEMAPHORE_MODE-less bAlive under weakly ordered systems. (5b193411 cont: "[*] Improve regressed AuWoA time to wake"
In all other cases, the memory is either thread-local write-local or followed up by an indirect aquire/release of the processors pipeline and L1 cache by virtue of the containers dumb spinlock ::Lock, ::Unlock (...release, ...barrier)
Clang doesn't have /volatile:ms anymore so we cant rely on that
Assuming MSVC-like or x86 isnt good enough

(and, no retard midwits, volatile is a fine keyword. take ur spec sperging and shove it. i just need to control over-optimization of defacto-weakly ordered access between explicit lockless semaphore yields)
