Conversation
Let a user connect a third-party account once and have any pixlet app that declares it render with a fresh access token, instead of pasting client ids, secrets and refresh tokens into app config forms. Issue tronbyt#184 was closed not_planned because a shared integration would give every self-hoster a different callback URL. This avoids that by changing whose credentials are used: the server admin registers their own OAuth app per provider and sets two env vars, and every user on the instance shares it the same way they share the server. No Tronbyt-org infrastructure, no pixlet changes, no app-developer secret-decryption key. A single stable /oauth-callback serves every provider; the in-flight provider name lives in the session, not the URL. Apps receive a plain access-token string in config[<oauth2 field id>]. That is deliberately not the Tidbyt contract (where the applet's own starlark handler exchanged a code and stored a refresh token): on a self-hosted server an app cannot refresh anything, since that needs the admin's client_secret and secret.decrypt returns None without Tidbyt's key. Refresh tokens never leave the server. Providers: - Strava redirect flow; comma-joined scopes, rotating refresh tokens - Spotify redirect flow; Basic-header token endpoint - GitHub device flow; public client, client id alone enables it Device authorization grant (RFC 8628) needs no redirect URI at all, which is what makes it work on a device with no public hostname. The user code is shown in the browser and rendered onto the matrix itself, so it can be read off the shelf and approved on a phone. The frame is built in pure Go through pixlet's render/encode packages and pushed under a fixed ephemeral name, so a re-push replaces the pending code rather than queueing stale ones. Notes on the details that are easy to get wrong: - Tokens are AES-256-GCM encrypted at rest under a key derived from the session secret_key. - A zero expiry means "never expires" (x/oauth2's own convention); treating it as expired refreshes on every render forever. - Refreshes are single-flighted per connection: Strava invalidates the old refresh token the moment a new one is issued, so a lost race can brick a connection. - Device flow forces AuthStyleInParams. Auto-detect sends Basic auth with an empty password for a public client, and since it only caches the style on success while every pending poll is an error, it probes both styles on every tick. - New GitHub OAuth apps issue expiring tokens by default, so the refresh path works without a client secret for public clients. - return_to rejects backslashes: url.Parse treats them as ordinary path bytes, but browsers normalise /\evil.com to //evil.com. Extracting a schema's oauth2 fields costs a full starlark evaluation, so results are cached against a fingerprint of the app's source files and revalidated with a stat. Directory-form apps (every app from the system repo) are fingerprinted per source file, since a directory mtime does not change when a file inside it is rewritten. Schema evaluation failures are not cached, so a transient error cannot pin an app as "has no oauth2 fields" for the life of the process. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Adds Google to the Connections registry so pixlet apps declaring a schema.OAuth2 field on accounts.google.com (e.g. a GA4 dashboard app) get a working Connect button. Redirect flow only — Google's device-flow scope allowlist excludes API scopes like analytics.readonly. Google only issues a refresh token when the authorize redirect carries access_type=offline, and only guarantees one on re-auth with prompt=consent. Those parameters are load-bearing, so Provider gains an AuthCodeParams field and the connect handler now asks the provider for its authorize-redirect options instead of hardcoding them; providers without an override keep the previous behavior (offline + forced consent via oauth2.ApprovalForce, which spells prompt=consent since the library dropped the legacy approval_prompt Google now rejects). No Identify callback: userinfo would require an email/profile scope beyond what the app's schema declares. Google doesn't rotate refresh tokens on refresh, which the existing omitted-refresh-token path already handles. Docs cover the consent-screen 'Testing' pitfall (7-day refresh tokens until the admin publishes to production). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Google has no Identify callback (userinfo would need a profile scope the app doesn't request), so its connection carries no display name or external id. The connections page rendered that as "Connected as " with nothing after it, and the app config page as "Connected as Google". Both now say "Connected" when there is no account label.

📝 WalkthroughWalkthroughThis change adds per-user OAuth2 account connections. It introduces provider configuration, encrypted token storage, code-flow and device-flow handlers, schema-based token injection for apps, new UI pages and translations, and database migration support for the ChangesOAuth2 connections
Estimated code review effort: 5 (Critical) | ~100 minutes Merge Risk: 🟠 High · up to The new connection flows can lose or suppress device authorization codes, remain stuck on stalled requests, and expose stored OAuth credentials to a predictable fallback key. These issues should be resolved before merge. Sequence Diagram(s)sequenceDiagram

in .env.example lines 78-84 and docs/oauth-connections.md lines 78-84, remove
the “no verification needed” assertion at docs/oauth-connections.md line 195,

In `@internal/connections/service.go`:
- Line 80: Configure a service-owned HTTP client with a finite timeout via
oauth2.HTTPClient for the OAuth flows in ExchangeCode, refresh, StartDeviceAuth,

internal/connections/service.go: lines 80, 275, 362, and 382; preserve each
caller context so cancellation continues to work.
In `@internal/connections/spotify_test.go`:
- Around line 46-48: Replace the four parse-error t.Fatalf branches with
require.NoError(t, err), using the existing Testify import or adding it where
needed. Apply this in internal/connections/spotify_test.go at lines 46-48 and
65-67, and internal/connections/google_test.go at lines 50-52 and 111-114.
In `@internal/server/connections_inject.go`:
- Around line 203-205: Update the guard in annotateSchemaForUI to also return
schemaJSON when s.Connections or s.DB is nil, alongside the existing nil
registry and empty-schema checks, preventing processing without either required
dependency.
In `@internal/server/device_code_image.go`:
- Line 28: Update the device-code image lifecycle around deviceCodeImageName to
prevent concurrent flows for the same user from deleting each other’s frames:
either reject or replace an existing per-user flow, or track frame ownership and
clear the image only when it belongs to the terminating flow.
- Line 188: Update the frame-writing flow around os.WriteFile to write the image
bytes to a temporary file in the same directory, then atomically rename that
file to the target path. Ensure temporary files are cleaned up on failure and
preserve the existing file permissions and error propagation.
In `@internal/server/handlers_device_flow.go`:
- Line 208: Update the error handling check around errors.As in the device-flow
handler to use errors.AsType with *oauth2.RetrieveError, capturing the typed
error and success boolean, while preserving the existing conditional behavior.
- Line 142: Update handleDeviceFlowStart’s call to pushDeviceCodeToDisplays to
use an application-owned bounded context instead of r.Context(), ensuring
display rendering remains independent of request cancellation while retaining a
finite timeout.
In `@internal/server/server.go`:
- Line 207: Update NewServer so failure of rand.Read while generating a missing
secret_key returns an initialization error and prevents server startup; remove
the predictable time.Now().UnixNano fallback before the generated key reaches
the Secret field.
In `@web/templates/manager/configapp.html`:
- Around line 1737-1740: The OAuth2 field’s user-facing strings are hardcoded
English. Update the affected flash notes and labels around the OAuth2 rendering
logic—including “Connected as,” “Connected,” “Disconnect,” and both Connect
labels—to receive translated values via {{ t .Localizer "MessageID" }}, reusing
the existing en.json/de.json message IDs and preserving the current rendering
behavior.
In `@web/templates/manager/deviceconnect.html`:
- Around line 74-75: Update the JavaScript status messages in the device
connection flow, including the messages at the Connected, error, and
disconnected states, to use template-defined translated values via {{ t
.Localizer "MessageID" }}; replace the hardcoded English text while preserving
the existing HTML/icons and status behavior.
- Line 68: Update the status polling flow around the fetch call to use an
AbortController and abort timeout capped at the remaining time until deadline.
Pass the controller signal to fetch while preserving the existing expiry
handling so aborted or completed requests continue through the deadline check
and next-poll logic.

Bound all OAuth requests with a finite-timeout HTTP client.
ExchangeCode, refresh, StartDeviceAuth, and CompleteDeviceAuth pass contexts to golang.org/x/oauth2 without setting oauth2.HTTPClient. The library falls back to http.DefaultClient, which has no timeout. A stalled provider can block callback or render-refresh work until the caller context ends and can hold a device-flow poll until its flow deadline. Attach a service-owned client with a finite timeout through oauth2.HTTPClient while preserving caller cancellation.

GORM v1.31.2 gorm.G generic API nil *gorm.DB implementation
💡 Result:
In GORM v1.31.2, the gorm.G[T] API provides a type-safe way to perform CRUD and query operations using Go generics [1][2][3]. It is designed to be used with a standard *gorm.DB instance [1][4]. Regarding your query about a nil *gorm.DB implementation, please note the following: 1. Interaction with gorm.G: The generic API constructor gorm.G[T](db *gorm.DB) requires a valid, initialized *gorm.DB instance [4][3]. Passing a nil *gorm.DB will result in a runtime panic when methods are called on the returned generic interface, as the implementation attempts to access internal fields and configuration of the DB instance [5]. 2. Handling nil DBs: If your goal is to handle or mock database interactions without a real *gorm.DB (for example, in unit tests), the recommended approach is not to pass a nil pointer, but to either use a mock database driver or wrap your database operations in an interface [6]. GORM objects are structs, and they do not support being nil in any functional capacity [6]. 3. Generic Database Interface: The term generic database interface is often used in GORM documentation to refer to the method db.DB, which returns an *sql.DB object from the current *gorm.DB instance [7][8]. This allows for low-level interaction with the underlying connection pool (e.g., calling Ping or setting connection limits) [7][8]. If the underlying connection is not a *sql.DB (such as during an active transaction), this method returns an error rather than nil [7][5]. In summary, GORM v1.31.2 requires a non-nil *gorm.DB to operate its generic API. If you are experiencing nil-related issues, ensure your database connection is properly opened via gorm.Open before passing it to gorm.G[T] [4][9].

Add s.Connections == nil and s.DB == nil to the guard. A recognized OAuth2 provider can make annotateSchemaForUI call methods on a nil s.Connections, which can panic. The same path passes s.DB to GORM, which requires a non-nil database. Return before processing the schema when either dependency is nil.

Go 1.26 errors.AsType standard library release notes
💡 Result:
Go 1.26 introduced the errors.AsType[E error](err error) (E, bool) function in the standard library as a type-safe, generic alternative to errors.As [1][2][3]. Key details regarding errors.AsType include: Functionality: It searches the error tree (the error itself and any wrapped errors obtained via Unwrap() or Unwrap() []error) for an error that matches the specified type parameter E [2][4]. If a match is found, it returns the error value and true; otherwise, it returns the zero value of E and false [2][3]. It supports custom matching logic for types that implement the As(any) bool method [2][4]. Benefits over errors.As: Type Safety: Because it uses generics, the target type is specified at compile time, eliminating the need to pass a pointer to a variable and avoiding potential pointer-to-pointer or type-assertion errors [3][5][6]. Clean Scoping: The returned error variable is scoped directly to the block where it is used (typically an if statement), which is more idiomatic than declaring a variable before the check [3][5][6]. Performance: It is generally faster than errors.As as it avoids some of the overhead associated with reflection [1][5][7]. While errors.As has not been deprecated, errors.AsType is the recommended approach for new code [3][8][7]. top_results: [1][2][3][5][6]

Summary
Lets a user connect a third-party account (Strava, Spotify, GitHub, Google) once, after which any pixlet app that declares a
schema.OAuth2field for that provider renders with a fresh access token automatically — no more registering your own OAuth app, scraping?code=out of an error page, and pasting refresh tokens into the config form.This is the model that sidesteps the blocker that closed #184: the server admin registers one OAuth app per provider with their instance's callback URL (
https://<tronbyt>/oauth-callback), setsXYZ_CLIENT_ID/XYZ_CLIENT_SECRET, and every user on that instance shares it — the same way they share the server. No Tronbyt-org infrastructure, no pixlet changes, no app-developer secret-decryption key. The full design write-up is indocs/oauth-connections.md.What's in the box
/oauth-callbackfor every provider (the in-flight provider lives in the session, not the URL).RenderAppand the schema-handler endpoint map eachschema.OAuth2field'sauthorization_endpointhost to a provider, mint a fresh token (refreshing if it's within 60 s of expiry, single-flighted per connection because Strava rotates refresh tokens), and setconfig[field.id]to the bearer token. Schema extraction is cached per(path, mtime, size)so it costs ~1 µs per render, not a second Starlark execution./connectionspage to manage accounts, and a Connect/Connected/Disconnect control rendered in place of every OAuth2 field on the app config page. Scopes declared by the app's schema are requested as-is;DefaultScopesonly fills in when the schema declares none.Google
Added for a GA4 dashboard app (
schema.OAuth2onaccounts.google.comwith theanalytics.readonlyscope). Redirect flow only — Google's device-flow scope allowlist excludes API scopes like Analytics. Google only issues a refresh token when the authorize redirect carriesaccess_type=offline+prompt=consent, soProvidergained anAuthCodeParamsoverride and the connect handler asks the provider for its authorize options instead of hardcoding them (existing providers keep exactly the previous behaviour, pinned by a test). Refresh responses don't rotate the refresh token, which the omitted-refresh-token path already handles. NoIdentifycallback (userinfo would need a profile scope the app doesn't request), so the UI shows a plain "Connected" state.The authorize redirect the server actually produces:
Admin caveat, documented in
.env.exampleand the doc: a Cloud project whose consent screen is in "Testing" issues refresh tokens that expire after 7 days. Publishing it to "In production" (no verification needed — users click through a warning; the 100-user lifetime cap is irrelevant for self-hosting) makes them durable.Screenshots
