||
## Session state (last updated: 2026-08-12)
|
||
|
||
- **Branch:** `main` — the social bar v2 push is **committed + pushed** (`9873eed`,
|
||
18 files, +1878/−321, 112 tests passing, 0 warnings). Working tree is **dirty
|
||
with the post-push docs backfill only** (ai.md, README.md, TASKS.md schema
|
||
section, THIRD-PARTY-NOTICES.txt) — ready to commit when the user says so.
|
||
- **Finished this session (round 3):** user's live-test report said the mastodon
|
||
icon still didn't show for `@gramps@llamachile.tube`. Root cause: the identity
|
||
domain `llamachile.tube` is YunoHost-SSO-gated — `/.well-known/nodeinfo`,
|
||
`/@gramps`, and webfinger all answer with the SSO login page, so nodeinfo
|
||
returned nothing and the icon fell back to the honeycomb glyph. The real
|
||
instance lives at `mastodon.llamachile.tube`, and only the bare root
|
||
`https://llamachile.tube/` 302s to it ("default app" redirect). Fix:
|
||
`HttpSocialValidator.TryFetchFediverseSoftwareAsync` now, when nodeinfo on the
|
||
identity domain fails, follows the root redirect (`ResolveInstanceHostAsync`,
|
||
reads `resp.RequestMessage.RequestUri.Host`) and re-runs the nodeinfo lookup
|
||
on the resolved host. New test `FediverseHandle_RootRedirectToSubdomain_ResolvesSoftware`.
|
||
Build: **0 warnings**. Tests: **112 passing**.
|
||
- **What landed (all rounds this session):**
|
||
1. **Fediverse icon resolution** — `DetectService` maps `@user@domain` to the
|
||
new `SocialService.Fediverse` (was `Link`/chain icon). On validate,
|
||
`HttpSocialValidator` best-effort GETs `https://{domain}/.well-known/nodeinfo`,
|
||
follows the first nodeinfo `links[].href`, reads `software.name`, and returns
|
||
it in `SocialLookupResult.FediverseSoftware`. `SocialEntry`/`SocialSlotViewModel`
|
||
carry `FediverseSoftware`; `SocialServiceIcons.LogoDataForFediverse(software)`
|
||
maps it to a bundled logo (mastodon/peertube/pixelfed/misskey/lemmy/pleroma/
|
||
firefish — Simple Icons CC0), falling back to the `FediverseIconData`
|
||
honeycomb glyph for unknown software (GoToSocial/Sharkey/Akkoma aren't in
|
||
Simple Icons). Nodeinfo failure still validates — the glyph falls back.
|
||
2. **Redirect resolution (round 3)** — identity domains that 302 their root
|
||
to the real instance (YunoHost default-app subdomains) resolve software via
|
||
the root redirect when identity-domain nodeinfo is SSO-blocked.
|
||
3. **Persistence** — new `SocialEntry.Software TEXT` column via
|
||
`MigrateSocialEntryTable()` (column-presence pattern, same as the others);
|
||
saved/loaded alongside Service/Handle/ProfileUrl.
|
||
4. **Icon colors** — `IconButton` style gains `Foreground="#d0d0d0"`
|
||
(`Themes/Controls.xaml`); the dialog's trash button overrides
|
||
`Foreground="#e94560"` (`SocialsDialog.xaml`). All other `IconButton`
|
||
usages are `Path` content with explicit `Fill`, so unaffected.
|
||
- **Landmines:**
|
||
- `LayoutStore.Socials` is only populated by `Load()` — tests must call
|
||
`store.Load()` before asserting it.
|
||
- `DetectService("justaname")` → **Website** with empty handle; only
|
||
unparseable input or `@user@domain` yields Link/Fediverse.
|
||
- Dialog sign-in provider is `Func<Task<YouTubeChannel?>>`; test fakes must
|
||
return `Task.FromResult` (sync-completed) so the fire-and-forget command
|
||
settles before the next assert.
|
||
- `SocialBarBottomTop = 1040` literal lives in `MainWindow.xaml.cs` (the VM's
|
||
`MasterFrameHeight` is private).
|
||
- `Cancel_AbortsInFlightValidation_WithoutMutatingSlot` relies on the
|
||
BlockingValidator's gate completing synchronously (no
|
||
`RunContinuationsAsynchronously`) — the assertions run after
|
||
`Gate.TrySetResult` returns because the awaited continuation executes inline.
|
||
- Nodeinfo cancellation test cancels mid-lookup via a counting stub; the
|
||
post-fetch `ct.IsCancellationRequested` check is what reports `Canceled`.
|
||
- Round-3 redirect fallback fires only when identity-domain nodeinfo fails;
|
||
the root follow happens automatically (HttpClient default auto-redirect),
|
||
and `RequestMessage.RequestUri.Host` is read from the final response.
|
||
- **Next step:** TASK 4 ship step 3 — the encoder + RTMP push (FFmpeg subprocess:
|
||
frames via stdin, stderr health parsing, FLV mux + push to the cached reusable
|
||
stream's ingestion URL). Nothing else queued — do not expand the task queue on
|
||
your own.
|
||
|
||
- **Secret/DB/port facts live:** OAuth client id/secret in `Helpers/OAuthCredentials.cs`;
|
||
OAuth session token in `Helpers/TokenStore.cs` (DPAPI → `%APPDATA%\ytLlive\ytLlive.auth`);
|
||
layout DB `%APPDATA%\ytLlive\ytLlive.db` (schema v8; the new `SocialEntry.Software`
|
||
column is a column-presence migration like the others, no version bump); OAuth callback
|
||
`http://localhost:8765/oauth2/callback`; crash log `%APPDATA%\ytLlive\startup.log`.
