From 3949dcfce95af4bd305f258ff5b170d7d50435f6 Mon Sep 17 00:00:00 2001 From: SulfurNitride Date: Sun, 12 Apr 2026 21:04:15 -0500 Subject: VFS perf fixes, icon/stylesheet compat, download filename fix VFS: - Open backing fd at mo2_open time for read-only handles so mo2_read can splice without re-opening the file on every read call. - Bump RLIMIT_NOFILE at mount time to fit the resulting fd pressure when the game keeps hundreds of BSAs open. - Dedicated node_cache_mutex so resolveByInode / mo2_lookup stop racing unordered_map writes while multiple tree_mutex readers are active. - max_read=1MB + matching conn->max_read and raised max_readahead/max_write so the kernel merges Wine's small sequential reads into bigger FUSE requests. - Per-op wall-clock counters in mo2_init() logs so we can distinguish VFS latency from game-side work. Proton launch: - Write dxvk.conf to the prefix and set DXVK_CONFIG_FILE to force dxvk.enableGraphicsPipelineLibrary=False, avoiding long GPL compile stalls on first run. UI / plugin compat: - Clamp IconDelegate's per-icon width to [8, 16] so narrow content columns don't trigger QIcon::pixmap(0,0) returning null and logging "failed to load icon" every repaint. - Pre-create lowercase symlinks in the stylesheet directory so QSS files authored on Windows resolve url(foo.svg) when on-disk files are Foo.svg. - Flip content icons empty-chessboard.png and facegen.png to 8-bit RGBA so Qt's built-in PNG reader loads them uniformly. - Add mobase.Version.canonicalString shim for legacy Python plugins that still call the old VersionInfo method on appVersion()'s return. - BSPluginList: compare normalized plugin name lists instead of byte hashes so the post-run case-fix refresh stops spuriously firing the "load order changed" dialog. - BSPluginList disabled by default. Download manager: - Parse CDN URL with QUrl + QUrlQuery and read the filename from the response-content-disposition query param (RFC 6266 quoted / unquoted / ext-value forms), not QFileInfo on the raw URL. - When the API or URL gives us a CDN object key (no archive extension), prefer the actual Content-Disposition header from the live response in metaDataChanged and downloadFinished.
