Creates the high-level HTTP client library the PostIt UI will
consume to manage blog posts, circles, and per-post ACLs.
Clients in this commit:
- BlogApiClient (moved from PostIt/Services; same public surface,
now depends on IYavscApiClient instead of the concrete class).
- CircleApiClient (new): GET/POST/PUT/DELETE /api/circle. Takes
the blogs base URL explicitly in its constructor so it doesn't
need to know about PostIt's Settings type.
- BlogAclApiClient (new): GET/POST/PUT/DELETE /api/blogacl.
Same conventions as CircleApiClient.
DTOs (Yavsc.Api.Client.Dtos):
- CircleDto: id, name, ownerId, public. Stops short of the
navigation properties on the server-side Circle (Owner,
Members), which depend on ApplicationUser and other server
types we don't want to drag into the client.
- CircleAuthorizationDto: circleId, blogPostId, comment. Same
reason: the server entity has Target and Allowed navigation
properties the client never needs.
The clients now require the caller to pass the blogs base URL
explicitly in the constructor (previously the BlogApiClient
sniffed it off YavscApiClient.Settings.BlogsApiUrl, but that
field is PostIt-specific). The one production call site
(App.axaml.cs) and four test call sites are updated to pass
the URL.
Build + 51/51 tests green. The IYavscApiClient abstraction was
landed in the previous commit so this one could be a pure
addition + relocation.
Yavsc.Api.Client is the new home for high-level HTTP clients
(BlogApiClient, CircleApiClient, BlogAclApiClient, etc.). It
depends on the host application's transport layer, but the host
(PostIt) is a UI app with OIDC, settings, and an ApplicationData
directory — none of which the abstract client library should
know about.
The IYavscApiClient interface captures just the transport
surface those clients need:
- HttpClient (so the client can configure BaseAddress)
- CallAsync<T> and CallAsync (the JSON over HTTP verb)
It deliberately leaves out LoginAsync / TrySilentLoginAsync /
CurrentAccessToken / HasValidSession / Settings — those are
authentication and configuration concerns, not transport. They
stay on the concrete YavscApiClient in PostIt.Services.
The concrete YavscApiClient now implements IYavscApiClient; the
existing public surface is unchanged (no breaking changes for
existing call sites in PostIt or the tests).
This commit only lays the foundation. The actual high-level
clients (Blog/Circle/BlogAcl) land in a follow-up commit that
re-uses this interface, so this one stays a small, reviewable
refactor.
BlogPost is shared between the server (Yavsc.Server/Models/Blog/
BlogPost.cs is the EF entity) and any client that talks to the
blogs API. Keeping the client-side DTO in PostIt.Models made
sense when there was only one consumer; now that the
Yavsc.Api.Client project is about to host BlogApiClient alongside
CircleApiClient and BlogAclApiClient, the DTO has to live in a
layer both the client project and PostIt can reference without
inverting the dependency.
Yavsc.Abstract is the existing home for cross-tier interfaces
and DTOs (IBlogPost, IBlogPostPayLoad, IApplicationUser).
Yavsc.Blogspot is the sub-namespace already used by the
matching interface, so the new concrete class follows.
Why not move Circle and CircleAuthorizationToBlogPost at the
same time? Both depend on the concrete ApplicationUser class
(via the Owner and Target/Allowed navigation properties) which
lives in Yavsc.Server. Moving them would mean either dragging
ApplicationUser into the abstract layer (huge blast radius —
auth, billing, chat, etc.) or weakening the navigation
properties (breaks EF Core shaping). They're staying where
they are; the new Yavsc.Api.Client will get DTO counterparts
instead.
Updated call sites:
- 4 .cs files: replace 'using PostIt.Models;' with
'using Yavsc.Blogspot;' where the file was actually using
BlogPost. Files that only used SignaturePadData keep their
'using PostIt.Models;' — that type stays put.
- 1 .axaml file: xmlns:models="using:PostIt.Models" ->
xmlns:models="using:Yavsc.Blogspot" (one DataTemplate for
the post list in MainPage).
Build + tests green (51/51).
Closes the data-leak holes that survived the move of these controllers
from Yavsc.Api to Yavsc.Blogs. Circles are personal — a circle and its
membership should never be visible, modifiable, or deletable by anyone
other than its owner.
BlogAclApiController:
- GetBlogACL() was returning the full table; now filters by
Allowed.OwnerId == caller's uid, with an Include(a => a.Allowed)
so EF Core can push the filter into SQL instead of materialising
the whole table.
- Other endpoints (GetById, Put, Post, Delete) already enforced
ownership; left as is.
CircleApiController:
- GetCircle() (no id) now filters by OwnerId.
- GetCircle(id) now requires c.Id == id && c.OwnerId == uid;
returns 404 (not 403) on miss to avoid leaking the existence of
someone else's circle.
- PutCircle verifies the existing record is owned by the caller,
then forces circle.OwnerId = uid on the body (the client's value
is ignored). Returns ChallengeResult when the caller doesn't own
the record.
- PostCircle forces circle.OwnerId = uid (was trusting the body).
- DeleteCircle now filters by OwnerId; 404 on miss.
All checks use the same source of truth (User.FindFirstValue(
ClaimTypes.NameIdentifier)) that the existing BlogAclApiController
authz code already relies on.
These two controllers belong to the Blogs subsystem (their routes
/api/blogacl and /api/circle are blog-domain concerns, not the
generic Api surface). Moving them next to BlogApiController keeps
related code together and prepares the PostIt client to consume
them through the same BlogsApiUrl base address as the existing
BlogApiClient.
Mechanical changes only:
- Namespace Yavsc.Controllers -> Yavsc.Blogs.Controllers
- Drop unused 'using Yavsc.Helpers;' (no symbol in the new
compilation unit depends on it; the build confirms it was
dead since the controllers were first written)
- Fix typo in CircleApiController route: 'api/cirle' -> 'api/circle'
(any client trying to call the documented route was hitting 404)
No functional changes to authorization or query shape. The known
security gaps in these controllers (GetBlogACL and GetCircle
return unfiltered collections, DeleteCircle has no ownership
check) are deliberately left untouched in this commit and will
be addressed in a follow-up.
ConfigureBillingService() walks AppDomain.CurrentDomain.GetAssemblies()
and calls Assembly.GetTypes() on each. If any of the loaded assemblies
has a type that fails to resolve (a flaky dependency, an AddOn with a
broken reference, a test dependency that's been rewritten after compile),
GetTypes() throws ReflectionTypeLoadException (or, less commonly,
FileNotFoundException / TypeLoadException for the assembly itself).
In CI on the forgejo-runner (and especially in test discovery under
xunit v3), one such assembly is loaded somewhere between test runs and
silently throws. The exception is not handled, so:
1. Collections are Cleared at the top of ConfigureBillingService().
2. The reflection loop throws before reaching the
RegisterBilling<HairCutQuery/HairMultiCutQuery/RdvQuery> calls.
3. BillingService.Billing ends up empty (Count = 0).
4. The second ConfigureBillingService() call sees the same assembly
loaded (xunit v3 keeps the AppDomain warm for the whole suite),
throws identically, and the test
Yavsc.BillingServiceTests.ConfigureBillingService_CanBeCalledTwiceWithoutThrowing
fails with 'Assert.Equal() Failure: Expected 3, Actual 0'.
Fix: catch ReflectionTypeLoadException and use the partial
.Types() list (the successfully-resolved subset), and use a
broader catch (with continue) for any other assembly-level
load failure. The lost user-settings types are not material;
they are derived from ApplicationDbContext in a separate loop
right after, and the RegisterBilling<>() calls that populate
BillingService.Billing run last, after both reflective phases
have completed best-effort.
The test still passes locally because the local test environment
loads a clean set of assemblies; only the CI runner (with its
extra test-time tooling) hits this path.
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 b12c272d:
- 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,
quand ne pas écrire de test).
- src/Yavsc.Tests.Shared/README.md : détails du scaffold partagé
(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
la page d'erreur elle-même) parce que DisplayTemplates
/ApplicationUser.cshtml faisait `var avuri = "/Avatars/" +
Model.UserName + ".s.png"` : avec <Nullable>enable</Nullable>,
Razor émet un null-check implicite sur Model.UserName et lève
NullReferenceException quand l'auteur n'a pas de UserName
posé (donnée héritée, user partiellement initialisé).
- UserDisplayHelpers.AvatarSrc : helper statique pur dans
Yavsc.Abstract.Identity qui retourne
YavscConstants.DefaultAvatar pour user null / UserName vide
ou whitespace, et un path /avatars/<name>.s.png sinon.
- ApplicationUser.cshtml : utilise le helper.
- Tests : 4 cas (null, vide, whitespace, valide) dans
Yavsc.Org.Tests/NonRegression.
Bonus : le path d'avatar passe de "/Avatars/" (S majuscule,
ne résolvait pas dans le middleware de fichiers statiques) à
YavscConstants.AvatarsPath ("/avatars" minuscule), pour fermer
l'autre trou que centraliser le calcul permettait de fixer
proprement.
Tout billet a un auteur, tout commentaire a un auteur. On aligne la
base sur ce contrat (Postgres) en droppant les orphelins existants
puis en remplaçant les FK en cascade par des FK Restrict.
- ApplicationDbContext: fluent pour BlogPost.Author et Comment.Author
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,
puis drop+add des FK. Down laisse la cascade (état pré-migration).
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.
