* workerized RA * Workerized (non-async) web player, using OPFS This patch eliminates the need for asyncify and uses modern filesystem APIs instead of the deprecated, unmaintained BrowserFS. This is a WIP patch because it won't fully work until these two Emscripten PRs land and are released: https://github.com/emscripten-core/emscripten/pull/23518 https://github.com/emscripten-core/emscripten/pull/23021 The former fixes an offscreen canvas context recreation bug, and the latter adds an equivalent to BrowserFS's XHR filesystem (but without the hazardous running-XHR-on-the-main-thread problem). The biggest issue is that local storage of users who were using the old version of the webplayer will be gone when they switch to the new webplayer. I don't have a good story for converting the old BrowserFS IDBFS contents into the new OPFS filesystem (the move is worth doing because OPFS supports seeking and reading only bits of a file, and because BrowserFS is dead). I've kept around the old libretro webplayer under pkg/emscripten/libretro-classic, and with these make flags you can build a non-workerized RA that uses asyncify to sleep as before: make -f Makefile.emscripten libretro=$CORE HAVE_WORKER=0 HAVE_WASMFS=0 PTHREAD=0 HAVE_AL=1 I also moved the default directory for core content on emscripten to not be a subdirectory of the local filesystem mount, because it's confusing to have a subdirectory that's lazily fetched and not mirrored to the local storage. I think it won't impact existing users of the classic web player because they already have a retroarch.cfg in place. * Get fetchfs working without manifest support * makefile fixes * fix scaling, remove zip dependency * Support asset/cheats/etc downloaders for emscripten - Add http transfer support for emscripten - At the task_http level, not the net_http level --- so no netplay or webdav. - Change default paths to be more like other platforms - Gives us smaller bundles and a faster boot time - Had to work around a task queue bug on Emscripten - I made the smallest possible change to do it, but it may be better to fix in rthread.c * Load an emscripten file_packager package on first run If no ozone assets are present, load a libretro_minimal package created using Emscripten's built-in file packager. * updated readme, removed indexer from wasmfs libretro-web * Put back zip dependency, load asset bundle into opfs on first run * fix upload path * Remove unused function * easy testing setup for two multithreaded conditions 1. make PROXY_TO_PTHREAD=1 (slower) 2. make PROXY_TO_PTHREAD=0 (bad audio, because doesn't sleep in openal.c) * Remove condition on sleep in openal also make input_driver check existence of drv->axis, drv->button before calling them. * Fix resizing under EGL * Don't force config file path on emscripten * Add time.h include to netplay, default HAVE_NETPLAYDISCOVERY to 0 * Remove nearly all proxied joypad calls under emscripten * Fix file uploads under firefox * Fix safari API uses, but Safari still hangs in OPFS filesystem mount I think this can be fixed by moving the backend creation off the main thread. * Move filesystem init into emscripten C entry point * Setup filesystems off of main thread * re-set default player to async Also improve Safari compatibility under proxy-to-pthread condition * Safari upload file fixes * Remove some excess prints * Fix typo
