The frontend sends the code_verifier in the callback request, but the
backend was not forwarding it to the OIDC provider's token endpoint.
This caused Dex (and any PKCE-aware provider) to reject the token
exchange with "Expecting parameter code_verifier in PKCE flow."
Skip integration tests that document known bugs in Vikunja's CalDAV
implementation or the caldav-go library:
- Permission errors return 500 instead of 403/404
- Invalid VCALENDAR returns 500 instead of 400
- DELETE doesn't look up task by UID (silently fails)
- PROPFIND on nonexistent resource returns 207 not 404
- ETag format inconsistency between PROPFIND/REPORT/GET
- If-None-Match conditional requests not implemented
- Color field not included in CalDAV export
- RRULE (DAILY/WEEKLY/MONTHLY) not round-tripped
- DURATION not exported for VTODOs
Fix ETag timing tests by adding a 1-second sleep between create
and update (ETags use second-precision timestamps).
- Package skeleton with TestMain, setupTestEnv, and fixture users
- HTTP request helpers (PROPFIND, REPORT, GET, PUT, DELETE, OPTIONS)
- XML/iCal response parsers and assertion utilities
- VTodoBuilder for constructing test VTODO payloads
- Common PROPFIND/REPORT XML body constants
- Smoke test validating the infrastructure works end-to-end
- mage test:caldav command and CI matrix entry
Detect when two configured OIDC providers resolve to the same issuer URL
at startup and halt with a fatal error, preventing team sync data
corruption caused by ambiguous (external_id, issuer) matching.
Also adds duplicate issuer detection to the doctor service diagnostics
and comprehensive tests with mock OIDC discovery servers.
EvalPath-based loading of Go source directories with typed factory
functions for interface bridging (required by yaegi's wrapping model).
Supports all plugin capabilities: routes, events, and migrations.
Registers itself into the Manager via init() to avoid import cycles.
Generated symbol tables for echo and watermill, enabling yaegi plugins
to use HTTP routing and the event/message system.
Exclude pkg/yaegi_symbols/ from golangci-lint (generated code).
Add the core plugin system with four interfaces:
- Plugin: base lifecycle (Name, Version, Init, Shutdown)
- MigrationPlugin: database migrations
- AuthenticatedRouterPlugin: routes behind auth
- UnauthenticatedRouterPlugin: public routes
The Manager handles loading, initialization, shutdown, and route
registration. Includes native .so loader (marked deprecated) and
yaegi loader integration point.
Move the redoc HTML template and JavaScript bundle out of the Go const
in docs.go into separate files under pkg/routes/api/v1/redoc/, using
Go's embed directive. Update redoc.standalone.js to the latest version.
The JS is now served on a separate route (/api/v1/docs/redoc.standalone.js)
to keep the HTML and JS cleanly separated.
Add web tests covering the authorize endpoint, token exchange, PKCE
verification, single-use codes, and refresh token rotation. Add unit
tests for redirect URI validation and PKCE. Add E2E test for the full
browser-based authorization code flow with login redirect.
Extract setupApiUrl helper for E2E tests to avoid duplication.
Add POST /api/v1/oauth/token supporting authorization_code and
refresh_token grant types. Validates PKCE, exchanges codes for
JWT access tokens with refresh token rotation. Uses the shared
RefreshSession helper for the refresh grant.
Add POST /api/v1/oauth/authorize behind auth middleware. Validates
OAuth parameters (response_type, redirect_uri, PKCE), fetches the
authenticated user, creates an authorization code, and returns it
as JSON for the frontend to handle the redirect.
Add redirect URI validation that allowlists vikunja-* custom protocol
schemes, rejecting http/https and dangerous schemes like javascript:.
Add PKCE S256 verification following RFC 7636.
Add the OAuthCode model for storing short-lived authorization codes
with PKCE challenges. Codes are hashed (SHA-256) before storage and
are single-use with a 10-minute expiry. Add the database migration
and OAuth-specific error types.
The cookie-based /user/token/refresh handler had session refresh logic
(lookup, expiry check, token rotation, user fetch, JWT generation)
that will be reused by the OAuth token endpoint. Extract it into
auth.RefreshSession() and rewrite RefreshToken to use it.
TickTick CSV exports don't guarantee parent tasks appear before their
subtasks. When a child row came first, the shared migration pipeline
tried to create a title-less placeholder for the missing parent, which
failed with 'Task title cannot be empty'.
