The Yavsc.Org integration tests were failing 'Internal Server Error' on
the OIDC discovery document when run as part of the full test suite.
Root cause: WebHostFixture bound Kestrel to IPAddress.Loopback on a
dynamically-allocated port and exposed it via IServerAddressesFeature.
But the OIDC issuer URLs (and the issuer claim) come from Site:Authority,
which was left at the production value (mercure.pschneider.fr). So
IdentityServer8's discovery document advertised URLs unreachable from
the test process, and the discovery call returned a 500.
Fix:
- WebServerFixture now overrides Site:Authority and Site:ExternalUrl
in AddInMemoryCollection to 'https://localhost:44300' (the ASP.NET
Core dev HTTPS convention).
- WebHostFixture reads Site:Authority from configuration and binds
Kestrel to that fixed URL. The exposed Addresses list is sourced
from the same configuration value instead of the
IServerAddressesFeature, so the listen URL and the OIDC issuer
URLs always match.
Remoting.cs (Mandatory/Remoting.cs): add 'using
Microsoft.Extensions.DependencyInjection;' so the existing OIDC/DB
diagnostic block (capture raw HTTP response + dump OIDC-related DB
state on discovery failure) compiles. The diagnostic itself is left
in place — it's what surfaced the 500 in the first place.
LoadClientAsync(id) on ClientController used to trip an
IndexOutOfRangeException at the InMemory shaper for any
.Include() of one of three Client navs: RedirectUris,
AllowedScopes, AllowedGrantTypes. Five other Client navs (with
the same EF shape and the same application-level config) worked
fine.
Bisection pointed at the InMemory provider; that hypothesis was
wrong. The real cause is in ApplicationDbContext.OnModelCreating:
yavsc was redeclaring the HasOne<Client>().WithMany(...).
HasForeignKey(e => e.ClientId) for all eight Client* navs. The
same relation is already declared (more completely, with
.IsRequired().OnDelete(DeleteBehavior.Cascade)) by
IdentityServer8's ConfigureClientStore via ModelBuilderExtensions.
The redundant mapping on three specific entities — ClientScope,
ClientRedirectUri, ClientGrantType — interacts with the InMemory
provider's shaper in a way that throws IndexOutOfRange. Removing
the redundancy fixes it.
This commit also walks back e940a241:
- Drops .AsSplitQuery() from LoadClientAsync (no longer needed
for the InMemory shaper, and the Postgres path it was a hedge
against was a false alarm — there is no Postgres production
bug here, only an InMemory shaper quirk surfaced by the
redundant mapping).
- Removes the 9 Bisect_*_alone tests that were the artefact of
the provider-hypothesis phase. They pointed at the right
entities but for the wrong reason.
- Keeps EditRedirectUris_GET_after_add_lists_both_uris as the
end-to-end regression sentinel: with the fix in place, it
loads a Client with two RedirectUris and asserts both are
rendered. Without the fix, it fails with IndexOutOfRange.
LoadClientAsync chains 9 .Include() calls on dbContext.Clients.
On Postgres (and InMemory for some IdentityServer8 nav types), the
resulting cartesian product trips the query shaper with
IndexOutOfRangeException at IncludeCollection materialisation time.
Bug reproduces in production on the Blog admin pages that load a
Client by id.
AsSplitQuery() rewrites the load as 9 separate SELECTs joined by
client id, which sidesteps the cartesian explosion and any shaper
ambiguity between Claims/Properties/ClientSecrets (which share
Type/Value column names across some IdentityServer8 versions).
Tests:
- EditRedirectUris_GET_after_add_lists_both_uris: end-to-end
reproducer that adds a second RedirectUri via POST then re-GETs
the editor. Guards the fix on the integration path.
- Bisect_*_alone: nine unit tests that exercise the same
.SingleOrDefaultAsync(c => c.Id == id).Include(nav) on the
InMemory provider, one nav at a time. Pinpointed three
problematic navs (RedirectUris, AllowedScopes, AllowedGrantTypes)
on InMemory; kept as a regression net for any future shaper
regressions on the InMemory provider (not the Postgres path).
TestWebApplicationFactory used ASPNETCORE_ENVIRONMENT=Development, which
caused Program.Main's AddConfiguration("org") to load the tracked
appsettings-org.json (the reference file with the
'*** via dotnet user-secrets ou variable d'environnement ***'
placeholder connection string). Npgsql then failed to parse that
placeholder during host startup, failing six integration tests
(observed 2026-07-11: System.ArgumentException on
NpgsqlConnectionStringBuilder.set_Item).
Switching the test host to a dedicated Testing environment makes
AddConfiguration("org") pick up the new optional
appsettings-org.Testing.json file as the last source in the chain
(JSON → env vars), which overrides YavscConnection with the
InMemory marker and the Smtp section with the test stub values.
The .gitignore exception whitelists this file explicitly: it is a
configuration source for the test host, not a secrets file.
The WebServerFixture path is unchanged — it owns its
WebApplicationBuilder and adds the same in-memory override via its
BuildApp hook.
Le commit 2 a fixé la NPE du /BlogSpot/Details/{id} en passant
le display template par UserDisplayHelpers.AvatarSrc, qui
défend contre un UserName null. Ce commit complète le filet
de non-régression et pose la doc d'architecture des tests.
- ApplicationUserDisplayTemplateTests : assert que le cshtml ne
concatène plus directement Model.UserName (ancien code fautif)
et qu'il utilise bien le helper. Si quelqu'un revert la ligne
4 du cshtml, les tests cassent. Les autres usages de
Model.UserName (alt, title, asp-route-id) sont autorisés : ils
ne sont pas la cause du 500, juste laids si null.
- doc/testing.md : vue d'ensemble de la stratégie de test
(conventions NonRegression/Mandatory/Smoke/Controllers, EF
in-memory via InMemoryDatabaseRoot partagé, auth stubs,

(WebHostFixture + son cycle de vie et ses hooks,
TestAuthPolicyProvider, TestTokenIssuer) et des deux
spécialisations dans le repo
(Yavsc.Org.Tests.WebServerFixture et
Yavsc.Blogs.Tests.BlogsWebServerFixture).
- doc/README.md : entrée vers testing.md dans l'index.
GET /BlogSpot/Details/1 retournait 500 (avec un 500-sur-500 sur

Bonus : le path d'avatar passe de "/Avatars/" (S majuscule,

Tout billet a un auteur, tout commentaire a un auteur. On aligne la

en DeleteBehavior.Restrict.
- ApplicationUser: ajoute la nav inverse BlogComments (manquait,
EF aurait sinon créé une shadow FK).
- Migration 20260711173717_EnforceBlogAuthorFKs: Up purge les
Comment/BlogSpot dont l'AuthorId n'existe plus, log le volume,

Le code applicatif (BlogSpotService.Details) s'appuiera sur cette
contrainte dans un commit séparé.
The 'Save' button in PostIt has been returning 400 from
/api/v1/blog ever since the editor's title and article fields
were re-bound to SelectedPost.Title / SelectedPost.Article.
The user types into the editor, taps Save, the controller
rejects with 'The Title field is required', and the PostIt
status bar shows only the generic 'Response status code does
not indicate success: 400' — no field name, no reason.
Three pieces here make the regression diagnosable and pin a
test for the fix:
1. YavscApiClient: replace EnsureSuccessStatusCode() at both
call sites with a small helper that reads the response
body and embeds it in the thrown HttpRequestException. The
VM's existing catch (Exception) in ExecuteAsync forwards
ex.Message to the status bar, so the next 'click Save'
tells the user exactly which field the server rejected.
2. Yavsc.Blogs.Tests: two integration tests on the real
controller (no HTTP mock) — one pins that a well-formed
PostIt-shaped payload (Title + Article + AuthorId + dates,
Id=0) is accepted with 201, the other pins that a payload
with Title=string.Empty is rejected with 400. Together they
pin the contract the VM has to honour.
3. PostIt.Tests: a red [AvaloniaFact] UI test that mounts
MainPage inside a headless Window, types a title into the
TextBox without first selecting a post in the list, taps
Save, and asserts the body of the first POST contains
the typed title. Today this test fails with Title='',
reproducing the production 400. The matching fix (a
Title/Article buffer on MainPageViewModel that the XAML
binds to, and that Save uses to build the outgoing
BlogPost) is the next commit; the test is the safety net.
Three related changes that close the loop on the DarkMode
field and lay the first stone of a UI test scaffold for
PostIt.
1. Settings.DarkMode was previously a dead field. It round-
tripped through postit-settings.json and the SettingsPage
CheckBox, OnDarkModeChanged flipped IsDirty, and that was
it — no consumer ever read the value, so toggling the
CheckBox had no visible effect. The fix is in
App.OnFrameworkInitializationCompleted: read the value
Load() just populated and set
Application.Current.RequestedThemeVariant accordingly
(so a dark-mode user lands on a dark window on first
launch, not on a default-light window that flips after
the user touches the toggle), then subscribe to
settings.PropertyChanged and update the theme on every
DarkMode change. The consumer lives in App.axaml.cs, not
in Settings, so the Settings model stays free of any
Avalonia.Application dependency and the SettingsLoadTests
(which construct Settings outside an Avalonia host)
still pass unchanged.
2. MainPageViewModel had a vestigial [ObservableProperty]
ThemeVariant themeVariant = ThemeVariant.Default that no
XAML, no code, and no test ever read. It was the start of
a half-finished attempt to expose the theme variant on
the page VM. The dark-mode wiring above makes it
irrelevant: the theme is now driven by Application, not
by a VM property. The field is removed, along with the
using Avalonia.Styling; it pulled in (now unused).
3. SessionStatusBannerTests adds the first set of UI tests
for PostIt. They mount a real MainWindow via the headless
Avalonia host declared in TestApp.cs, attach a
SessionStatusViewModel as the banner's DataContext, and
assert the actual visual tree contents: three buttons
render (Se déconnecter, Se connecter, Paramètres), the
Login button is visible when logged out, the Logout
button is hidden when logged out, the Paramètres button
is visible regardless of session, and the session label
text reflects the VM. The pattern follows what
UnitTest1.MainPage_Should_Load already established:
[AvaloniaFact] (from Avalonia.Headless.XUnit) plus
new MainWindow() / window.Show(). A plain [Fact] cannot
drive Window..ctor() because the headless platform's
PlatformManager.CreateWindow() has no service registered
outside a dispatcher-aware test context; the
AvaloniaFact attribute provides that context. The
DataContext is set on the banner directly because
App.OnFrameworkInitializationCompleted is not called in
a unit test (production wiring is exercised by the
manual launch, not here).
Build: 0 errors. Tests: 5/5 SessionStatusBannerTests,
3/3 SettingsLoadTests, 1/1 MainPageTests (the existing
scaffold test, unchanged). The other PostIt.Tests suites
depend on the OIDC stub WebApplicationFactory and time out
on this network-restricted host.
Two related changes that close the loop on the SettingsPage
push semantics.
1. The SettingsPage used to be registered as Transient. Each
click on the Paramètres button resolved a fresh instance,
re-bound it to the Settings singleton, and pushed it onto
the navigation stack. Repeated clicks accumulated stacked
instances, each fully bound, and the user had to tap Back
N times to leave. The fix is to register the page as a
Singleton in the DI container. There is now one and only
one SettingsPage ContentPage for the lifetime of the app:
- its DataContext is wired once, at composition time
(just after the ViewLocator is added to DataTemplates),
not on every push;
- the OpenSettingsRequested handler is a pure navigation
concern, with no DI resolution and no rebinding;
- the in-memory Settings state is preserved across visits
(any in-flight edit stays in the same instance).
2. The OpenSettingsRequested handler is guarded so that if the
SettingsPage is already at the top of NavigationStack, the
push is a no-op. NavigationPage.PushAsync does not
deduplicate; without the guard, calling it twice with the
same instance pushes it a second time, and the user has to
tap Back twice to leave. The guard is a reference comparison
on NavigationStack[Count - 1] against the singleton
instance, which is correct precisely because the page is
a singleton.
doc/architecture/postit.md is updated to match: the DI table
reflects the new lifetime, and the 'Garde anti-empilement'
section is rewritten from 'to be implemented' to the actual
implementation, including the rationale for reference
comparison and the cross-dependency between the singleton
lifetime and the guard.
The Settings-singleton invariant (in the same doc) is
unchanged: Settings is still a singleton, and adding a
transient override would still be the bug it always was.
The new SettingsPage singleton sits alongside it cleanly.
Build: 0 errors. Tests: 3/3 SettingsLoadTests green.
Two long-standing gaps in the architecture documentation are
filled in this commit:
1. doc/architecture/postit.md is new. It covers everything the
existing postit-oidc.md does not: the one-codebase /
three-frontends topology (PostIt lib + PostIt.Desktop +
PostIt.Android + PostIt.Browser), the custom ViewLocator
that resolves ViewModel -> View through the DI provider
(and why we don't use the Avalonia.Mvvm default), the
composition root in App.OnFrameworkInitializationCompleted
with the full DI registration table, the navigation flow
driven by SessionStatusViewModel events, the ViewModel
lifetime conventions (singleton vs transient), the
[RelayCommand] XAML binding conventions (referenced to
AGENTS.md for the canonical version), and the per-page
DataContext / role table. The Settings-singleton invariant
is called out as a guard rail, and the SettingsPage
anti-empilement invariant is documented as the TODO the
code still owes us.
2. doc/architecture/decoupage-organisation.md is brought up to
date. Its project table listed 7 .csproj; the repo has 14
(the four PostIt projects, the tests satellites, the cli
tool). The table is extended, the ASCII diagram picks up
the PostIt block, and an Outils et tests section lists
the test / CLI satellites that were missing.
doc/README.md is updated to index the new postit.md. No code
changes in this commit, no behaviour change.
Two changes to the PostIt settings surface, both in service of
the same observation: opening the Settings page did not reflect
the loaded state, and edits to Authority / ClientId did not
persist.
1. Settings was registered twice in the DI container: once as
a singleton (the already-Load()'d instance) and again as a
transient, with the transient registration winning. The
Settings page's DataContext was therefore a brand-new,
empty Settings instance on every push — Authority and
ClientId bound to null, and even if the user typed into the
fields, the edits landed on the throwaway instance and were
silently lost. The fix is the obvious one: keep Settings as
a singleton and drop the transient override.
2. The Scopes field of AuthenticationSettings is a string[],
which doesn't bind to a TextBox without a converter. The
Settings page already shows the other auth fields as plain
TextBoxes, so the same treatment is given to scopes via a
new space-separated view property:
- AuthenticationSettings.ScopeListText (string,
[ObservableProperty], [JsonIgnore]) is the view.
- OnScopeListTextChanged splits on any whitespace and
re-assigns Scopes, skipping the write when the parsed
array is element-wise equal to the current one to avoid
a PropertyChanged loop with OnScopesChanged.
- OnScopesChanged keeps ScopeListText in sync when
Scopes is reassigned from outside (JSON hydration,
MergeScopes, programmatic updates), again short-
circuiting when the textual representation hasn't
changed so the TextBox caret doesn't flicker on load.
- RefreshScopeListText is the explicit re-sync entry
point; Settings.ApplyJson calls it after a successful
hydration to normalise any whitespace the JSON might
have introduced.
SettingsPage.axaml gets a new Scopes row between ClientId
and the Blogs API URL; the Grid.RowDefinitions are bumped
to 13 to match. Scopes remains the on-disk format — only
ScopeListText is presentation.
The shape of the on-disk postit-settings.json is
unchanged: [JsonIgnore] on ScopeListText, and the
serialization path in Settings still round-trips Scopes
directly. MergeScopes in Settings.GetOidcClientOptions is
untouched.
Tests: 3/3 SettingsLoadTests passing (PostIt.Tests);
PostIt.csproj builds clean (0 errors). The other PostIt.Tests
suites depend on the OIDC stub WebApplicationFactory and
time out on this network-restricted host, so we trust the
unit-level coverage and the build.
Extract the kid calculation out of LoadSigningCredentialsInner
into a new internal static HostingExtensions.ComputeKid(string),
and cover it with five focused unit tests in
Yavsc.Org.Tests.ComputeKidTests.
The kid is the bit of signing-credential metadata that ties a
JWT to the right key in the JWKS. Without it, resource servers
(Yavsc.Blogs, Yavsc.Api) fail signature validation with IDX10500
'The signature key was not found', as fixed in 91516aee. That fix
inlined three lines of thumbprint-truncation logic at the top of
LoadSigningCredentialsInner, but left the calculation untested.
The tests in this commit pin its shape, value, stability, and
uniqueness, so a future refactor (e.g. switching from SHA-1 to
SHA-256, or moving to X509CertificateLoader for SYSLIB0057) has
to update them deliberately instead of silently changing the
JWKS key id.
Concretely:
- InternalsVisibleTo("Yavsc.Org.Tests") in AssemblyInfo.cs
gives the test project access to the new internal method
without forcing LoadSigningCredentialsInner to leak
further.
- ComputeKid(string) is the single source of truth for the
16-hex truncation; the production call site in
LoadSigningCredentialsInner now reads
'var kid = ComputeKid(certPath);'.
- The inline comment block is updated to say SHA-1 (which is
what X509Certificate2.GetCertHash() actually returns) instead
of the previous SHA-256 claim. The behaviour is unchanged.
- ComputeKid uses X509CertificateLoader.LoadCertificateFromFile
rather than the obsolete 'new X509Certificate2(string)' ctor
(SYSLIB0057); same on-disk behaviour, no obsolete warning.
Tests cover:
- 16-char upper-case hex output matching the first 16 hex
chars of the cert's GetCertHash();
- stability across repeated reads of the same cert;
- distinctness between two independently generated certs;
- the SHA-1 size of the underlying thumbprint (20 bytes), so
a future switch to SHA-256 forces a test update;
- CryptographicException propagation for a missing cert file
(Assert.ThrowsAny to stay portable across the Linux OpenSSL
and Windows leaf exception types).
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.
SettingsPage.axaml had TextBox / CheckBox TwoWay bindings to the
Settings singleton, but no Save button — user edits mutated the
in-memory instance and were lost on the next launch. This commit
addes the missing save path:
- Settings.Save() writes the current instance to
~/.config/PostIt/postit-settings.json (symmetrical to Load),
with 0600 POSIX permissions matching TokenStore.Save.
- Settings.IsDirty ObservableProperty flips to true on every
setter that flows through the four top-level
[ObservableProperty] fields (DarkMode, BlogsApiUrl,
BusinessApiUrl, plus the OnAuthenticationChanged partial for
the Authentication sub-property). Sub-property edits
(Authentication.Authority / ClientId / RedirectUri / Scopes)
are caught by a PropertyChanged subscription wired up in
OnAuthenticationChanged and re-wired on each Authentication
reassignment.
- [RelayCommand(CanExecute = nameof(CanSave))] on Save itself
emits the SaveCommand ICommand that the XAML binds to.
OnIsDirtyChanged calls SaveCommand.NotifyCanExecuteChanged()
so the button auto-enables / auto-disables. The Avalonia
binding is 'SaveCommand' without a suffix — the source
generator emits that property name from the Save method.
- ApplyJson resets IsDirty = false at the end so disk / embedded
loads don't leave the page stuck in dirty state.
- SettingsPage.axaml: fixed the RowDefinition count (4 rows
declared, 10 used — controls at rows 4..9 were rendering
outside the grid), and added a Sauver button at row 10 bound
to SaveCommand with IsEnabled driven by !IsDirty.
Build: dotnet build src/PostIt/PostIt/PostIt.csproj → 0 errors.
Tests: 45 / 45 passing.
Two intertwined jobs here:
1. Diagnostic test for the production 401 we see when PostIt
talks to Yavsc.Blogs. The hypothesis this test isolates:
the access token sent on the wire is missing the 'blogs'
scope that Yavsc.Blogs' BlogScope policy requires (see
Yavsc.Blogs/Program.cs: RequireClaim(JwtClaimTypes.Scope,
"blogs")). The test fakes a single HttpMessageHandler,
captures the outbound bearer, decodes the JWT, and asserts
the 'scope' claim contains 'blogs'. It does not stand up a
server, an OIDC stub, or any network listener. Result: the
scope is present in the access_token we construct, so the
401 is not on the client side — most likely the IdP at
Yavsc.Org is not issuing 'blogs' as a recognised scope.
2. Mechanical fix of the three test files that broke during
the Settings model refactor (PostIt.Settings ->
PostIt.ViewModels.Settings; ApiUrl -> BusinessApiUrl;
Scopes/RedirectUri moved under Authentication;
DefaultDesktopRedirectUri is on AuthenticationSettings in
the global namespace). Also restored the BaseAddress
setup that BlogApiClient does in production in
LoginAndPersistAsync / the reloaded-client path of
YavscApiClientTests, so the two integration tests that
call CallAsync("posts") directly don't trip on
'request URI must be absolute or BaseAddress must be set'.
Test status: 45 / 45 passing in PostIt.Tests.
The "Paramètres" button on SessionStatusBanner was wired to a stub
OpenSettingsCommand with a TODO. With the Settings model refactor
(VM consolidated to ViewModels/Settings.cs, SettingsViewModel.cs
dropped, App.axaml.cs registering Settings instead of the old VM),
the navigation is now plumbed end to end:
- SessionStatusViewModel gains an OpenSettingsRequested event
alongside LogoutCompleted / LoginSucceeded, and the
[RelayCommand] body just raises it. VM stays decoupled from
NavigationPage and window lifetime, same pattern as the
existing banner events.
- App.axaml.cs handles the event in the desktop branch: resolves
SettingsPage (transient) and the canonical Settings singleton
(the one we Load()'d at startup and bound via
Settings.BindToServiceProvider) from DI, then PushAsync the
page on top of the current NavRoot stack. Two-way bindings on
SettingsPage mutate the singleton in place.
Build: dotnet build src/PostIt/PostIt/PostIt.csproj → 0 errors.
Existing CS8602 / NU1507 / CS8632 warnings unchanged.
The endpoint was a copy-paste from the IdentityServer template
documentation. It serialised the entire HttpContext.User claim set
to anonymous JSON, with no auth gate. In a public-facing deployment
that's exactly the kind of surface scrapers and botnets love
(it tells them whether their token is valid and what shape the
issuer uses), and it served no production purpose.
Side benefit: removes the ASP0004 analyser warning ("IActionResult
should not be returned from a MapGet Delegate") that came with
this line.
All [ApiController] classes (BlogApi, BlogTags, PostTags, FileSystem,
FileSystemStream, Comments, TagsApi) returned 404 on every route,
even though Kestrel was up. The pipeline in Program.cs was missing
MapControllers(), so the controllers were never attached to the
endpoint data source. MapIdentityApi and MapGet("/identity")
worked because they're explicit minimal-API routes; the attribute-
routed controllers didn't.
Confirmed end-to-end: GET /api/v1/blog now returns 401 (auth
required by [Authorize("BlogScope")]) instead of 404.
Two leftover bits of dead code that were just compiler noise:
- Settings.folder (IStorageFolder?, never read) plus the three
Avalonia / Avalonia.Platform.Storage usings that only existed
to type it. The picker-based flow was replaced by a direct
file-path read in Settings.Load, so the field has been a
CS0414 for a while. Just delete it.
- ViewLocator.Build / Match took 'object data' while the
IDataTemplate interface expects 'object? data', which is why
the compiler was complaining with CS8767 about nullability
mismatch on every implementation. Add an explicit null arm
in the switch so the default branch doesn't have to
dereference a possibly-null data either.
Login flow no longer needs a dedicated page. The OIDC interactive
login now lives on the persistent SessionStatusBanner, alongside
'Se déconnecter', driven by a new SessionStatusViewModel.LoginAsync
command. On success the VM raises LoginSucceeded and App.axaml.cs
pushes MainPage on top of HomePage — same path BootAsync already
takes when the silent refresh succeeds at boot, so the two flows
can't drift apart (PushMainPageAsync helper, single source of
truth).
MainPage no longer shows an editable AuthorId field: the server
infers the author from the bearer token, so the client-side
control was misleading at best. The detail grid drops from 5 rows
to 4.
Removed:
- Views/LoginPage.axaml + .axaml.cs
- ViewModels/LoginPageViewModel.cs
- HomePage Login button + OnLoginClick code-behind
- DI registrations for LoginPage / LoginPageViewModel
- ViewLocator mapping
- dangling <c>LoginPage*</c> cref / comments in Platform.cs,
PlatformBootstrap.cs (Desktop + Android), MainWindow.axaml,
YavscApiClient.cs
Wire the Blogs integration test host with a real AddJwtBearer
(HS256, IssuerSigningKey shared with the new TestTokenIssuer) and
the production BlogScope policy verbatim, instead of the
TestAuthPolicyProvider / AllowAllAuthorizationService /
NoopAuthHandler stack that short-circuited every authorization
check.
Why: BlogSpotService.Modify calls
IAuthorizationService.AuthorizeAsync(user, blog, EditPermission);
the previous AllowAllAuthorizationService stub made that a
no-op, so the tests could not exercise the real ownership chain
and any change in PermissionHandler would silently slip through.
The new test host registers the real PermissionHandler, so a PUT
that succeeds (204) is now proof that PermissionHandler.IsOwner
accepted the request — i.e. the JWT's sub matched the post's
AuthorId, end-to-end.
Notes for future-me:
- JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear() is
called once on the first Issue() to keep the 'sub' claim
literal; without it UserHelpers.GetUserId (which reads 'sub')
gets ClaimTypes.NameIdentifier instead, returns null, and the
owner check fails for every PUT. The companion
options.MapInboundClaims = false on the validation pipeline
keeps both sides in sync.
- Production still uses AddYavscJwtBearer against the OIDC
authority; the test-only HS256 path is local to the test
process and never crosses a network boundary.
Coverage:
- GetBlog_returns_401_when_no_token_is_provided — anonymous
request, real policy fails closed.
- PutBlog_with_valid_token_and_owner_returns_204_and_Get_
reflects_update — POST then PUT then GET, all behind a real
JWT, asserting 204 + list contains the updated title.
Packages added to Directory.Packages.props at 8.2.1 to match
what Microsoft.AspNetCore.Authentication.JwtBearer 10.0.9 already
transitively pulls in (no version drift).
BlogApiController.PostBlog called Request.Form.Files
unconditionally, which throws on a plain JSON body — the
exception is "This request does not have a Content-Type header.
Forms are available from requests with bodies like POSTs and a
form Content-Type of either application/x-www-form-urlencoded or
multipart/form-data."
That broke PostIt's first-bill-of-blog flow: the client posts a
BlogPost as JSON and has no files to attach. The endpoint
contract is [FromBody] BlogPost, so the JSON body is deserialised
into 'blog' as expected — only the IFormFileCollection argument
to BlogSpotService.Create needs a real-or-empty value.
Branch on Request.HasFormContentType: pass the form files when
present, pass an empty FormFileCollection otherwise. BlogSpotService
already short-circuits on a null/empty file collection, so the
JSON-only path is now a clean code path.
Tests: add PostBlog_creates_a_post_and_Get_returns_it_in_the_list
(POST a draft, assert 201 + server-assigned Id, GET the index,
assert exactly one entry with that Id). Add a per-test
ResetDatabase helper because the in-memory store is shared across
the lifetime of the BlogsWebServerFixture instance.
First behavioural test for the Yavsc.Blogs API surface. Sends a
GET on the blog index with the X-Test-Role auth bypass and asserts
the response is 200 with an empty JSON array — the in-memory
ApplicationDbContext has no rows, and BlogSpotService.Index returns
an empty enumeration.
While here, fix a routing miss: AddControllers() in the test
fixture was only scanning the test assembly, so BlogApiController
was never registered. Add the Yavsc.Blogs application part
explicitly. Without this, every request to /api/v1/blog came back
as 404 — the same symptom PostIt was seeing in production.
The POST flow lands in the next commit, once BlogApiController is
made to accept JSON (it currently requires multipart/form-data
because of Request.Form.Files).
Adds the test project that the next commit will use to assert the
blog API endpoints. The fixture inherits from the shared
WebHostFixture (commit "refactor: extract WebHostFixture…") and
wires up only the bits the blog API needs:
* In-memory ApplicationDbContext — BlogSpotService is used as-is,
no mock. The first tests will exercise the real service against
an empty table.
* Trivial IFileSystemAuthManager stub (the GET index path never
reads the file system).
* TestAuthPolicyProvider swapped in, so X-Test-Role satisfies
[Authorize("BlogScope")].
Two smoke tests verify the fixture boots and the controller
pipeline is reachable. The first behavioural test
(GET /api/v1/blog → 200) lands in the next commit.
Also promotes two xunit.v3.* package versions to the root
Directory.Packages.props so future test projects can share them.
Yavsc.Blogs.Tests will need a fixture too. Lifting the cross-cutting
plumbing (Kestrel + self-signed cert + address discovery + lazy init)
into a new Yavsc.Tests.Shared project lets the next fixture inherit
from it without copying 200+ lines of setup boilerplate, and keeps
the Org.Tests fixture focused on its IdentityServer + SMTP seed.
* New project src/Yavsc.Tests.Shared with WebHostFixture (abstract)
and TestAuthPolicyProvider (test auth bypass via X-Test-Role).
* WebServerFixture in Org.Tests now inherits from WebHostFixture;
BuildApp + ConfigurePipelineAsync hold only Org-specific work.
* Two shared package versions promoted to the root Directory.Packages.props.
* Tests still 30/30 green.
The previous "PostIt: fix blog API double-prefix" commit changed
DefaultPathPrefix from "api/blog" to "blog" without spelling out
the convention. Future-me (or anyone else touching ApiUrl) needs
to know that BaseAddress already terminates in /api/v1/ and that
pathPrefix is relative to that.
* BlogApiClient: add a <para> in the class summary that names the
convention, points at the matching controller route, and
cross-references the fix commit.
* postit-oidc.md: add a row in the "Composants partagés" table
with the same warning, in the architectural-doc voice.
BlogApiClient's "api/blog" path combined with the BaseAddress's
"api/v1/" prefix to produce 404s on every call. Drop the redundant
"api/" segment, let Save handle the create case (no selection) and
remove the now-redundant New button + command.
