feat(mobile): show project favicons in the thread filter menu - #11370
SunkenInTime wants to merge 5 commits into
Conversation
ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This cross-platform mobile feature adds asynchronous favicon fetching, native image conversion, shared menu plumbing, and a patched iOS image loader across the existing thread-filter path. An unresolved medium-severity finding also indicates that emoji, monogram, and Lucide project overrides can be replaced by a generic folder icon. Not approved because:

Fixes reproduced on an Android emulator and from upstream reports. Feed: Android stops drawing a text view past the GPU's maximum texture height, so a long list rendered as one selectable Text lost its tail and took seconds per frame to draw. Long lists now split into 40-item chunks. Wide assistant markdown blocks keep a pinned width; the feed reserves bottom padding. Keyboard: the feed re-pins after keyboard transitions settle and when the composer collapses; the back gesture collapses the composer; sticky composers only follow the keyboard after a fresh show or real focus (upstream pingdotgg#8212). Terminal: hardware Enter no longer moves focus off the terminal; keyboards that use deleteSurroundingText (FUTO) send Backspace; forward delete works. Also: stream haptics no longer buzz every 320ms on Android and all haptics use the system engine; thread settings apply on tap without Save; typed pairing codes are normalized to the server format; non-git projects fall back to the current checkout instead of a dead worktree default; user CA certificates are trusted; Ctrl/Cmd+Enter sends from a hardware keyboard; thread rename, project favicons in the filter, tablet sidebar toggle, desktop-window density, route titles, Material You review colors, bottom gesture-bar insets, and the composer placeholder clipping (upstream PRs pingdotgg#11503, pingdotgg#11370, pingdotgg#11339, pingdotgg#8200, pingdotgg#8717, pingdotgg#11445, pingdotgg#6003, pingdotgg#5052, pingdotgg#8362, pingdotgg#10709, pingdotgg#11611, pingdotgg#8800, adapted).

The Project submenu of the Android thread filter listed names only, while the thread list and new-task picker show each project's favicon. Android menu actions can now carry a leading view, and both filter menus (phone home and tablet sidebar) pass the existing ProjectFavicon there, sized to the menu's icon slot.

Projects with an emoji, monogram, or Lucide override display folder.fill in the iOS filter menu, so their identifying icon is lost. This guard discards the resolved glyph, and the final mapping only renders a fetched URI or FOLDER_ICON; render the override in the menu instead.

Bound the module-level favicon data-URI cache.
The backing cache limits each data URI to 32 KiB and trims itself to 128 entries or 1 MiB. The separate faviconDataUris map has no eviction. When a favicon revision changes, the hook can retain both the old and new data URIs indefinitely. Each new entry also copies the entire map.
Apply a bounded eviction policy to this module-level map. Match the existing favicon-cache entry and byte limits where practical.

Do not cache failed favicon loads as completed.
A failed fetch, HTTP response, or FileReader operation produces null. The current completion handler stores that null in faviconDataUris, and the effect then skips the same URL because getSnapshot().has(url) is true. The listener update can re-render the hook, but it does not change the effect dependency or schedule another load.
A connection recovery can leave the URL unchanged, so the folder icon can remain until the URL changes or the module state resets. This is a minor, recoverable fallback issue rather than a permanent failure. The upstream favicon cache may retain a confirmed missing-icon result, but that negative-cache behavior does not require this separate data-URI map to mark transient load failures as completed.
Suggested fix
.catch(() => null)
.then((dataUri) => {
pendingFavicons.delete(url);
+ if (dataUri === null) return;
faviconDataUris = new Map(faviconDataUris).set(url, dataUri);
for (const listener of listeners) listener();
});This allows a later effect run to retry the URL. The change does not schedule a retry by itself.

Bound remote favicon responses before native decoding.
Do not add a data:image/...-only guard. createProjectFaviconCache.resolve can return a remote URL after a cache miss, and useProjectFilterMenuIcons.ios.ts must fetch that URL to preserve valid favicon fallback.
Extract or reuse the existing bounded response reader. Apply PROJECT_FAVICON_MAX_SOURCE_BYTES before response.blob() and FileReader.readAsDataURL. Pass only bounded data URIs to the synchronous native decoder. The nullable completion already handles decode failures.

The Project submenu of the thread filter lists project names only, while the thread list and the new-task picker show each project's favicon.
Android menu actions can now carry an optional
leadingview, which the Material popup draws in the icon slot instead of a symbol. When any row in a menu has one, rows without it keep an empty slot so labels stay aligned, as Material menus do. Both filter menus (phone home screen and tablet sidebar) pass the existingProjectFaviconthere at the popup's icon size, so loading, caching, icon overrides and the folder fallback match the thread list.iOS menus are native UIKit menus, so the favicon has to arrive as a
UIActionimage.useProjectFilterMenuIcons(iOS only, a no-op elsewhere) resolves each project's favicon URL, fetches it to a data URI and passes it to the menu action as animageSource; projects without a favicon get thefolder.fillsymbol. react-native-screens loadsimageSourceicons through the async image loader and UIKit builds the menu before that finishes, so remote images never showed. The repo's react-native-screens patch gains a sync decode branch fordata:sources inRNSImageLoadingHelper.mm. The icon flows through the iOS 26 mail-style toolbar, the pre-26 header toolbar and the iPad sidebar header menu.Each project filter option carries the scope's representative project, the same one the new-task picker uses.
Verification: mobile typecheck, lint and fmt on the changed files;
home-list-filter-menu.test.tspasses. Android checked on a Pixel 8 emulator (Android 16) in light and dark mode. iOS checked on an iPhone 17 simulator (iOS 26.5, app 1.3.1) in light and dark mode against seeded projects with real favicons plus one without. The pre-26 toolbar and iPad sidebar share the same hook and were not exercised on a device.Android
