Bundled end-of-branch commit on feat/postit-acl-members.
PostIt UI for circles + per-post ACL
- Reorganise PostIt.Tests into Auth/ and Blogs/ subfolders
(Bearer/OIDC scope tests vs. blog API fakes live where they
belong) and introduces PostItHeadlessCollection so the
Avalonia.Headless tests share a single xUnit collection
instead of contending with the EF-Core test host.
- Adds BlogAclApiTests (a brand-new behavioural layer over
POST /api/v1/blogacl) and the fakes it relies on
(BlogApiTestFakes, BlogPostAuthorDtoTests, AddCircleMember
DialogTests); pulls UserId-through-OIDC-sub path into
BearerScopeTests / FakeAuthorizingBrowser /
OidcStubAuthority.
- App.axaml.cs gets a small PushPageAsync touch-up the new
tests rely on.
- Drops UnitTest1.cs (xUnit scaffold, never used).
Yavsc.Blogs.Tests — SQLite instead of InMemory
- Bumps Yavsc.Blogs.Tests.csproj on
Microsoft.EntityFrameworkCore.Sqlite and rewrites
BlogsWebServerFixture to hold a single shared
SqliteConnection (Cache=Shared) for the fixture lifetime,
with a sync Dispose close to dodge async teardown hangs.
Reason: the EF Core InMemory provider silently ignores FKs,
which masked the kind of bug we are about to pin in the
ACL tests. SQLite enforces them, so any future INSERT that
forgets to seed its parent rows fails loudly here instead
of passing the test and breaking prod.
- PublishEndpointTests and BlogApiSmokeTests get a one-line
tweak to follow the new connection lifecycle.
Foreign-key fallout: seed the default user in the fixture
- Adds BlogsWebServerFixture.SeedUser(userName). Now that
SQLite enforces BlogPost.AuthorId → AspNetUsers.Id, every
test that POST/PUT/DELETE a BlogPost and sends AuthorId=
'tester' in the payload needs an AspNetUsers row to satisfy
the FK or it returns 500 with SQLite Error 19.
- BlogApiTests wraps the existing ResetDatabase with a
ResetAndSeedDefaultUser helper for the six mutating tests;
the four GET-only and ModelState-only tests keep the bare
ResetDatabase.
- Side benefit: every test in Yavsc.Blogs.Tests now finishes
cleanly instead of hanging at teardown — previously a stuck
test held the shared SqliteConnection open and the next
tests waited indefinitely.
Verified: dotnet test src/Yavsc.Blogs.Tests passes 25/25
green from a clean run, no fixture teardown hang.
IdentityServer8 was emitting JWTs without a 'kid' header and
serving the JWKS without per-key identifiers, because
LoadSigningCredentialsInner constructed RsaSecurityKey /
ECDsaSecurityKey objects without an explicit KeyId. Resource
servers (Yavsc.Blogs, Yavsc.Api) cannot match a token to a key
in the JWKS without one, so every signature validation failed
with 'The signature key was not found' (Microsoft.IdentityModel
IDX10500).
Root cause: SigningCredentials were built directly from the
BC-parsed key parameters, bypassing the X509Certificate2 path
IdentityServer normally derives the kid from. The fix derives
a stable KeyId from the certificate's SHA-256 thumbprint
(truncated to 16 hex chars) and sets it on both SecurityKey
variants before constructing SigningCredentials.
The thumbprint-based kid is stable across process restarts as
long as the cert doesn't change, and changes naturally on
LetsEncrypt renewal (~90 days), which is the right behaviour:
old tokens age out, resource servers refresh their JWKS cache
to discover the new kid.
Production rollout: redeploy Yavsc.Org and re-login (or let
the refresh-token path rotate) so newly issued tokens carry
the kid. Pre-restart tokens will continue to be rejected with
IDX10500 until they expire or are refreshed.
