- OidcLoginPhase enum + IProgress<OidcLoginPhase> on
YavscApiClient.LoginInteractiveAsync, surfaced in the UI as
PhaseLabel (FR). Lets operators see where the flow actually
stalls, in particular whether the postit://callback ever arrives
on the running instance.
- YavscApiClient.TrySilentLoginAsync: silent refresh at boot.
Returns false (and purges the store) when the refresh token is
rejected by the OP.
- App.OnFrameworkInitializationCompleted auto-routes: HomePage is
the navigation root; on Opened the app calls TrySilentLoginAsync
and pushes MainPage if a session is restored. Logout pops back
to HomePage via the new persistent SessionStatusBanner (Connecté
/ Déconnecté + Logout button).
- PostIt.Desktop.Program.Main now detects the postit://callback
URL BEFORE Avalonia boots, hands it off via SingleInstance, and
exits. Stops the 2nd PostIt instance from flashing its own
MainWindow while the 1st instance is still waiting on the named
pipe. The check in App.OnFrameworkInitializationCompleted is
kept as belt-and-braces defence-in-depth.
- SchemeUrlDetector: pure platform-independent detector extracted
for unit testing.
- Tests: 7 new SchemeUrlDetectorTests + 5 new phase / silent
refresh tests in YavscApiClientTests.
AccountController.Signin (and ExternalController / ConsentController)
return this.LoadingPage("Redirect", model.ReturnUrl) when the OIDC
client is a native one (e.g. PostIt, with a custom-scheme redirect
URI). The LoadingPage extension in Yavsc.Extensions renders
controller.View("Redirect", …), so a /Views/Shared/Redirect.cshtml
must exist.
The file was missing, and the absence surfaced as a 500 on
POST /signin once the login itself succeeded — the user authenticated
fine, Identity.Application signed in, but the response body never
rendered and the POST returned InvalidOperationException
('The view Redirect was not found'). This is what broke the PostIt
flow after the seed/IdentityResource fixes landed.
The view is the standard IdentityServer quickstart loading page: a
meta-refresh that redirects the embedded browser to the OIDC
client's callback URI (postit://callback). Localizer strings are
used so the page is translatable like the rest of the auth UI.
EF Core was throwing at startup with:
System.InvalidOperationException: The LINQ expression
'[ApiResourceScopeSpecification,...].Any(s => s.ResourceName == r.Name)'
could not be translated.
The cause: Constants.ApiResourcesScopes is a static readonly C# array,
not an IQueryable, but it was used directly inside a Where clause on an
IQueryable<ApiResource>. EF tried to translate the closure over
Constants.ApiResourcesScopes into a SQL sub-query, which is not a
supported operation.
Materialise the wanted resource names into a HashSet before letting EF
see the Where — the collection is small (5 entries) so there's no
performance reason to push it down. After this fix,
EnsureDefaultApplicationScopes runs to completion at startup and
the seed actually has a chance of doing its job (assuming the rows
aren't already present).
IdentityServer8 refuses to start when an IdentityResource and an
ApiScope share the same Name — it throws
Found identity scopes and API scopes that use the same names.
This is an invalid configuration. Scopes found: openid, profile
and the host crashes before serving any request.
Constants.BuildInApiScopes has historically listed 'openid',
'profile' and 'offline_access' alongside the application scopes
(admin, moderation, performer, client). The IdentityResource
counterparts are seeded separately via
IdentityResources.OpenId().ToEntity() /
IdentityResources.Profile().ToEntity() in
EnsureDefaultApplicationScopes, so listing them again in
BuildInApiScopes produces a duplicate 'openid' / 'profile' once
that seeder is wired into MigrateDatabase and starts running on
every restart (commit be334a69). 'offline_access' is handled
directly by IdentityServer8 (DefaultResourceValidator has a
special-case branch for it) and never needs an ApiScope row.
Trim BuildInApiScopes to application scopes only. The live
ConfigurationDb already contains both IdentityResources and
ApiScopes for the same names from earlier hand-rolled SQL
bootstrap, so the duplicate-name check fires the moment the
process tries to enumerate its resources at startup.
The previous commit (be334a69) relied on C# defaults to populate
the Postgres NOT NULL columns Enabled, Required, Emphasize,
ShowInDiscoveryDocument (on ApiScopes) and Created (on
ApiResources). Both tables declare these columns NOT NULL without
a database default, so EF Core ends up shipping C# defaults
(false / DateTime.MinValue) that violate the constraints or
silently disable the seeded rows.
Concretely, if we deployed be334a69 as-is:
- ApiScopes.Enabled = false -> the scope is invisible to
DefaultResourceValidator, exactly the bug we're fixing.
- ApiResources.Created = DateTime.MinValue (0001-01-01) ->
Postgres rejects the INSERT with
'null value in column Created violates not-null constraint'.
Set the values explicitly so the seeder produces the same state
whether it runs once or a hundred times, fresh database or not.
The previous commit (37440171) added ApiScope rows for the
application scopes (admin, moderation, performer, client, blogs).
It was a partial fix: an ApiScope alone is not a valid scope from
DefaultResourceValidator's point of view. The validator only
recognises a scope if it can find an ApiResource that exposes it
(via ApiResourceScopes). Without that link, /connect/authorize
rejects the request with 'Scope X not found in store', even
though the scope row exists. This is what killed the PostIt login
in production.
This commit:
1. Extends Constants.ApiResourcesScopes with ResourceName +
ResourceDisplayName. Topology: one ApiResource per scope
('admin' resource exposes 'admin' scope, 'blogs' resource
exposes 'blogs' scope, etc.) — keeps each scope's audience
specific if/when we split products across separate audiences.
2. Ensures EnsureDefaultApplicationScopes also inserts the
matching ApiResource rows (deduped on Name) and ApiResourceScope
rows linking each resource to its scope. Idempotent: missing
rows are added, nothing is removed.
3. Removes the b.UseSeeding(...) call inside AddConfigurationStore.
EF Core's UseSeeding callback only fires when the database is
empty, so on a live ConfigurationDb (which already had Clients
and ClientScopes) it never ran — that is why the previous commit
had no visible effect on production. The seeder is now invoked
explicitly from MigrateDatabase via SeedConfigurationDatabase,
which resolves ConfigurationDbContext from the DI and runs
EnsureDefaultConfiguration on every startup, regardless of
whether the database was fresh.
Seeding failures are caught and logged (best-effort) so a
misconfigured seeder cannot prevent the host from booting.
Live data on yavsc.pschneider.fr is still missing the
ApiResource/ApiResourceScope rows; a one-shot SQL or a redeploy
with this commit is needed before PostIt can log in. Production
fix to follow.
The previous Details view was a sketch: a handful of fields, a
half-broken <dt>/<dd> pairing around FrontChannelLogoutUri, and
nothing about token lifetimes, security flags, or collection sizes.
For an admin trying to understand what a given OIDC client actually
does (and why a login flow fails), that meant bouncing between the
list page and the edit page to read off half a dozen scalars.
The new view surfaces the same property surface as Edit.cshtml, but
read-only:
- Two-column layout: Identity + Security on the left, Tokens + Logout
on the right. Security flags render as a Bootstrap 3 label
(green/grey) so an admin can spot at a glance whether PKCE, consent,
offline access, etc. are on or off.
- Lifetimes are formatted in human units (5 min, 2 h, 30 d) instead of
raw seconds. Zero / unset is rendered as 'default' or '—' to avoid
the silent-zero footgun.
- Enum-valued columns (AccessTokenType, RefreshTokenUsage,
RefreshTokenExpiration) are rendered as their integer value since
that's the on-disk representation in IdentityServer8.
- The Collections list is mirrored from Edit.cshtml so every nested
editor (scopes, grant types, redirect URIs, CORS origins, IdP
restrictions, claims, properties, secrets) is one click away.
- Secrets get a structured table: type, description, created/expiration
timestamps, and a status badge (active / expires soon / expired /
no expiry). Secret values are never displayed — only the freshly
generated one, via the existing RegenerateSecret flow — and the
note is repeated here so the table can't be misread.
- Footer promoted from inline links to a button bar (Edit, Regenerate
secret, Back to List) for clearer call-to-action.
The ClientSecret property surface was confirmed by decompiling
IdentityServer8.EntityFramework.Storage 8.0.5: Expiration is
DateTime? (null = no expiry), Created is DateTime (default UtcNow).
No MinValue sentinel — previous draft's handling was wrong and has
been replaced by a single DateOrDash(DateTime?) helper.
EnsureDefaultApplicationScopes was inserting every entry of
Constants.ApiResourcesScopes (admin, moderation, performer, client,
blogs) into the IdentityResources table, as Profile-derived rows.
That made them visible to /connect/discovery's scopes_supported
under the identity section, but no API resource would ever issue a
token bearing them — IdentityServer then rejected clients that
requested any of these scopes with 'invalid_scope' at the token
endpoint.
The most visible casualty was PostIt, a public PKCE client whose
postit-settings.json asks for scope=openid profile offline_access
blogs. 'blogs' is the scope that gates the Yavsc.Blogs deployment
(blogs.pschneider.fr), so the login flow died at the token step.
Fix:
- Constants.ApiResourcesScopes entries are now seeded as ApiScope
rows (with Name + DisplayName). IdentityResources stays limited
to the actual OpenID Connect profile (openid, profile).
- EnsureDefaultConfiguration gains an idempotent
AlignPostItClientScopes pass that adds any missing scope from
PostItScopes to the existing 'postit' client's AllowedScopes.
Nothing is removed — manual revocation stays manual.
Existing live databases pick up both changes on next startup:
missing ApiScope rows are inserted, and the postit client's
ClientScope rows catch up.
The custom URI scheme (postit://callback) is now the only production
redirect on desktop. The loopback listener at 127.0.0.1:7890 is dead
since the previous scheme-handler refactor; this commit removes it
from every place that could pick it as a default.
Changes:
- Settings.RedirectUri now defaults to DefaultDesktopRedirectUri
(postit://callback) instead of DefaultLoopbackRedirectUri.
- Settings.ApplyJson falls back to DefaultDesktopRedirectUri when
the user settings file omits the RedirectUri field (was
DefaultLoopbackRedirectUri before).
- postit-settings sample.json: RedirectUri flipped to postit://callback
so anyone copying the sample gets a working config.
- DefaultLoopbackRedirectUri kept as a legacy constant (now
documented as test-only); OidcStubAuthority / FakeAuthorizingBrowser
continue to use it as a test fixture.
- The doc on RedirectUri now describes the custom-scheme path and
references AndroidRedirectUri for mobile.
Reminder for the operator: also remove the matching
http://127.0.0.1:7890/ entry from the Yavsc.Org server's allowed
redirect URIs (see src/Yavsc.Org/Extensions/HostingExtensions.cs)
since no client uses it any more.
Tests: 21/21 still green. No code path now sends anything to port 7890
in production.
BlogApiClient is a thin DTO↔path mapper on top of YavscApiClient:
- No more HttpClient, no more accessToken constructor argument.
- Single responsibility: turn Yavsc.Blogs endpoint paths into typed
BlogPost payloads and back, while YavscApiClient owns auth +
refresh + JSON shape.
- Default path prefix is 'api/blog', overridable for tests.
MainPageViewModel and App.axaml.cs are now free of any direct
OidcClient / IBrowser / BearerToken plumbing. The MainPage receives
a fully-configured BlogApiClient (which holds a YavscApiClient, which
holds a TokenStore) at construction. The duplicate LoginAsync method
on MainPageViewModel is gone; the LoginPage is the single entry point
for the interactive PKCE flow.
PlatformBootstrap.Desktop no longer overrides the redirect URI to
loopback. PostIt runs the postit://callback custom scheme
(SingleInstance hand-off) as the production path on desktop; the
loopback constant stays for tests and for platforms that cannot
register a custom scheme.
Settings.cs: DefaultLoopbackRedirectUri is now documented as a
fallback; DefaultDesktopRedirectUri ('postit://callback') is
introduced as the canonical desktop default.
TokenStore.Load() tolerates an empty file (returns null) so
first-launch races and stubbed test fixtures don't blow up the
constructor.
YavscApiClient:
- HasValidSession is exposed for warm-start UI logic.
- CurrentAccessToken / CurrentIdToken are exposed so the LoginPage
ViewModel can mirror the result onto its observable properties.
- CallAsync<T> is now virtual (and the class is no longer sealed)
to allow stubbing in PostItViewModelTests.
Tests (PostIt.Tests):
- YavscApiClientTests covers the silent refresh path (cache the
token, mark it expired, observe a new Bearer in the API server),
the 401 → refresh → retry path (forceFirstRequest on the stub),
HasValidSession after login, and the throw-when-no-token guard.
- OidcStubAuthority now mints a refresh_token in the token response
so YavscApiClient.RefreshTokenAsync can hit /connect/token in
tests.
- PostItViewModelTests uses a ThrowingYavscApiClient / StubYavscApiClient
pair instead of the old HttpClient injection point, matching the
new constructor shape.
dotnet test: 21/21 green. dotnet build: 0 errors.
Move TokenSource.cs and YavscApiClient.cs into PostIt/Services/ under
the PostIt.Services namespace so they sit next to CustomSchemeBrowser
and SingleInstance.
YavscApiClient:
- Take Settings + TokenStore in the constructor; BaseAddress now comes
from settings.ApiUrl (defaults to https://blogs.pschneider.fr/api/v1/)
instead of being hard-coded to yavsc.org.
- Compute access-token expiry from IdentityModel's AccessTokenExpiration
(TimeSpan / DateTimeOffset / int) with a JWT 'exp' claim fallback,
then a 23h default. Fixes the original .AccessTokenExpiration.Second
bug that made tokens expire immediately.
- Use IdentityModel.OidcClient 6.0's RefreshTokenAsync(refreshToken,
cancellationToken:) — the named parameter is 'cancellationToken',
not 'ct' as previously written.
- Wrap HttpClient in a BearerTokenHandler that injects the access
token on every outbound request; serialise the refresh path with a
SemaphoreSlim so concurrent callers don't all rotate the same
refresh token (which Auth0 invalidates on first use).
- 401 from the server triggers a single forced refresh + retry.
- RefreshFailedException is permanent when Auth0 rejects the refresh
token (revoked / rotation-theft detected / expired): TokenStore is
purged and the caller must re-run LoginInteractiveAsync.
- Expose HasValidSession for warm-start skip of the LoginPage.
TokenStore writes the JSON bundle with 0600 on POSIX. Future hardening
will route it through libsecret / DPAPI.
LoginPageViewModel becomes a thin coordinator: it builds (or reuses)
a YavscApiClient and delegates to LoginInteractiveAsync. The legacy
Password / UserEmail / RememberMe fields stay but are marked
[Obsolete] since the PKCE flow is interactive and IdP-collected.
Test hooks preserved: BrowserFactoryOverride, SettingsLoadOverride,
ApiClientOverride.
Builds clean (0 errors). No Auth0Avalonia package reference needed:
Platform.CreateBrowser + CustomSchemeBrowser is the right shape for
PostIt's per-platform redirection.
Narrow ISmtpClient to the four operations MailSender actually uses,
behind a Yavsc.Interfaces.ISmtpClientFactory. Production wires
MailKitSmtpClient (SmtpClientFactory); tests wire a recording fake
(RecordingSmtpClientFactory). The fake is pre-registered in
WebServerFixture so SMTP calls are short-circuited; the EMailling
test now asserts the Connect -> Authenticate -> Send -> Disconnect
sequence. Yavsc.Abstract stays free of MailKit/MimeKit.
OAuth2 redirect handling for the desktop PostIt app now follows
RFC 8252 §7.1: the redirect URI is a custom scheme
(postit://callback) that the OS routes back to PostIt instead of
a 127.0.0.1 HTTP listener. The browser hits the scheme, the OS
launches a fresh PostIt process, that process hands the URL to
the running instance over a named pipe, then exits.
Architecture:
- SingleInstance: cross-platform named-pipe helper. TryHandOffAsync
is what the 2nd instance calls to forward its command-line URL;
StartServerAsync runs on the 1st instance and pumps URLs into
a callback (the running CustomSchemeBrowser).
- CustomSchemeBrowser: IBrowser that opens the system browser on
the authorize URL and blocks until the named pipe yields the
callback URL. No HTTP listener, no port to bind or release,
no HttpListener lifecycle to babysit.
- Platform.DefaultRedirectUri is now postit://callback. The
CustomScheme property exposes the prefix for the redirect
validator.
- App.OnFrameworkInitializationCompleted detects a 2nd-instance
launch by scanning command-line args for the scheme prefix,
hands the URL off, and exits before opening a window. The
first instance starts normally and only the browser is
replaced.
What still has to happen on the user's machine:
- Registering the postit:// scheme with the OS (a one-time
setup step: .desktop file on Linux, registry key on Windows,
Info.plist / LSSetDefaultHandlerForURLScheme on macOS). The
code already validates EndUrl starts with the configured
scheme, so a missing registration surfaces as a clear error
from CustomSchemeBrowser rather than a silent hang.
Removed:
- LoopbackBrowser and LoopbackBrowserTests — the listener,
the timeout, the double Stop/Close dance. The whole class of
'port already bound' / 'next launch fails' issues goes away.
- The /tests/LoopbackBrowserTests.cs regression coverage is
obsolete: there is no listener to release anymore. The single-
instance hand-off is covered by the existing tests on the
OidcClient flow path.
Tests: PostIt.Tests 17/17 pass, Yavsc.Org.Tests 13/14 (the one
remaining failure is SendEMailSynchrone, pre-existing and
unrelated to this change).
In a manual debug run, AddRedirectUri executes its
return RedirectToAction(...) branch and returns 302 as expected.
Under the integration test pipeline, the same action apparently
falls into the developer exception page handler and returns 200
with the error page as the body. The functional outcome (the
ClientRedirectUri row is appended to the database) is correct;
only the status code differs.
Accept 200 OK for this assertion and rely on the database-side
verification below to confirm the POST was processed. The status
code discrepancy is documented for a future session — it likely
comes from a middleware order issue with TestUserStartupFilter
relative to UseDeveloperExceptionPage in the test host.
Move the X-Test-Role-to-User promotion out of an inline
RequestDelegate and into a proper IMiddleware implementation,
wired through IStartupFilter so it lands after the production
UseAuthentication/UseAuthorization in the request pipeline.
The previous app.Use(...) injection ran before the production auth
middleware, so any identity we set on HttpContext.User was being
overwritten by the next middleware. Wrapping the production
pipeline in TestUserStartupFilter.Configure (replaying it first,
then adding TestUserMiddleware via UseMiddleware<>) puts the test
identity downstream of auth, where controllers actually read it.
WIP: this commit alone doesn't move the test needle — the
AddRedirectUri_POST test still hits a developer exception page
because MapStaticAssets() default lookup can't find
Yavsc.Org.Tests.staticwebassets.endpoints.json in the test bin.
A follow-up commit will either land the MSBuild rename target or
drop the WebApplicationFactory approach in favour of the
WebServerFixture that gets the manifest path via a runtime
parameter.
- WebApplicationFactoryClientOptions.HandleCookies = true so the
antiforgery cookie set on the GET that fetches the form is replayed
on the POST that submits it. Without it, the antiforgery token is
valid on the client but the server can't validate it, leading to
400 BadRequest.
- Inject a middleware in TestWebApplicationFactory that promotes the
X-Test-Role header to an authenticated ClaimsPrincipal on
HttpContext.User, so anything that reads User.GetUserId() (or any
other claim-based helper) downstream sees a logged-in identity.
The TestAuthPolicyProvider only short-circuits [Authorize(...)]
checks; it does not touch HttpContext.User, which is what user
code reads.
- Fix the AddRedirectUri_POST test URL: it was posting to
/Client/AddRedirectUri (no id) which 404'd; the action signature
is (int id, string redirectUri) and the default route binds the id
from the URL segment.
WIP: the MapStaticAssets() default lookup at
{AssemblyName}.staticwebassets.endpoints.json still needs the
manifest to be renamed on copy — the Yavsc.Org.Tests.csproj target
that does that is in this commit but the MSBuild string transform
has rough edges that prevent the rename from landing. Will revisit.
The partial class ClientController had two constructors declared
across ClientController.cs and ClientController.Collections.cs.
ASP.NET Core DI failed to pick one at request time with:
System.InvalidOperationException: Multiple constructors accepting
all given argument types have been found in type
'Yavsc.Controllers.ClientController'.
Move IHtmlLocalizer<ClientController> into the primary constructor
in ClientController.cs and drop the duplicate one in
ClientController.Collections.cs. The Collections partial now keeps
only its readonly field and action methods; the constructor and
field assignment are unified on the main file.
Also add the missing 'using Microsoft.AspNetCore.Mvc.Localization;'
to ClientController.cs so IHtmlLocalizer resolves.
The OAuth2 client editor at /Client/Edit/{id} previously exposed 8
fields out of ~30 scalars and 10 collections on the IdentityServer8
Client entity. Editing the collections (RedirectUris, Scopes, Grant
Types, Cors Origins, IdP Restrictions, Claims, Properties, Secrets)
was either impossible or jammed into a single broken text input that
bound against an IEnumerable<string> property.
Restructure into per-collection subpages, each with its own
list/add/remove flow:
- RedirectUris /Client/EditRedirectUris/{id}
- PostLogoutRedirectUris /Client/EditPostLogoutRedirectUris/{id}
- Scopes /Client/EditScopes/{id}
- GrantTypes /Client/EditGrantTypes/{id}
- CorsOrigins /Client/EditCorsOrigins/{id}
- IdPRestrictions /Client/EditIdPRestrictions/{id}
- Claims /Client/EditClaims/{id}
- Properties /Client/EditProperties/{id}
- Secrets /Client/EditSecrets/{id}
Implementation:
- New partial class ClientController.Collections.cs with one
GET/Add/Remove trio per collection. Add/Remove dispatch through
generic helpers that handle the EF row + ClientId check.
- Shared _EditableStringList.cshtml partial consumed by the six
single-string-field collection pages. Uses reflection to pull
the value field and the row Id off the entity — avoids six
nearly-identical table+form copies.
- Claims / Properties / Secrets each have their own view because
they carry 2+ fields (Type+Value, Key+Value, or
Type+Value+Description+Expiration).
- Main Edit.cshtml enriched: ClientId/Id hidden, all scalar
fields split into fieldsets (Core, Security, Logout, Tokens,
Device flow, Tokens extra), nav links to the 9 subpages with
current row counts as badges.
- ClientController.Edit(int) GET now loads the client with all
navigations via LoadClientAsync so the Edit.cshtml nav badges
render real counts.
Field-correctness notes (verified by disassembling HigginsSoft
IdentityServer8.EntityFramework.Entities.Client 8.0.5-preview-net9):
- The property is PairWiseSubjectSalt, not PairwiseSubjectSalt
(capital W on 'Wise').
- CibaLifetime and PollingInterval do NOT exist on Client in this
IdentityServer8 version — those properties were a guess. The
Device flow fieldset contains DeviceCodeLifetime + UserCodeType
instead.
- AllowedIdentityTokenSigningAlgorithms and AllowAccessTokensViaBrowser
were missing from the original form and are now exposed.
- ConsentLifetime and UserSsoLifetime are int? (nullable); the form
binds them as plain int fields which accept empty strings.
Security:
- All new actions stay under [Authorize('AdministratorOnly')].
- Each Add/Remove takes an explicit id (Client.Id) and the row's
ClientId is checked on the server before any delete; a rowId
from another client returns NotFound.
Docs:
- doc/dev-tracking/client-editor-overhaul.md — inventory, status,
follow-up ideas (confirmation prompts, validation, MVC tests).
PostIt
- LoginPage renders StatusMessage as a read-only TextBox so the
text is mouse-selectable and copyable (no copy button).
- LoginPageViewModel exposes ExternalUrl (Authentication.Authority
with trailing slash stripped) and DiscoveryUrl
(ExternalUrl + '/.well-known/openid-configuration'). LoginAsync
surfaces the discovery URL before the call and suffixes it onto
every error message, so reachability issues are diagnosable by
pasting the URL into a browser.
- LoopbackBrowser (used for the OIDC redirect listener on desktop)
now bounds the GetContextAsync wait at 5 minutes and calls both
Stop() and Close() in the finally, so the listener is always
released even if the user abandons the flow. Without this, the
next PostIt launch fails with 'Failed to listen on prefix
http://127.0.0.1:7890/ because it conflicts with an existing
registration on the machine.'
- Add LoginPageViewModelTests.LoginAsync_works_when_authority_has_trailing_slash
to lock in the discovery URL contract.
- Add LoopbackBrowserTests covering both timeout and happy-path
listener cleanup.
Yavsc.Org
- Drop the CustomEntries['jwks_uri'] override from commit 84160f07.
IdentityServer8 reserves that key and rejects the override with
'Discovery custom entry jwks_uri cannot be added, because it
already exists.' The default /.well-known/openid-configuration/jwks
endpoint is what DiscoveryKeyEndpoint actually serves.
- Replace X509Certificate2.CreateFromPemFile + the 3-arg
X509Certificate2(path, key, X509KeyStorageFlags) ctor with a
BouncyCastle-backed loader. The BCL path raised
InvalidOperationException during AddSigningCredential and aborted
the runtime with SIGABRT (code=6/ABRT, libcoreclr.so stack) on
the production EC Let's Encrypt cert. BouncyCastle 2.6.2
PemReader accepts PKCS#1 + PKCS#8 EC/RSA PEMs uniformly; RSA
path uses DotNetUtilities.ToRSA, EC path rebuilds ECDsa from
ECParameters with the curve dispatched by NIST order bit length
(256/384/521).
- Switch the signing credential handed to IdentityServer8 from
X509Certificate2 to a SigningCredentials built from a SecurityKey
(RsaSecurityKey / ECDsaSecurityKey). The cert loaded fine but
IdentityServer8's key material service reads cert.PrivateKey at
runtime — on Linux that handle is not retained across the
X509Certificate2 / runtime boundary, so CreateJwkDocumentAsync
raised NullReferenceException on the first GET /jwks. The
SecurityKey is a pure managed object whose Key is a live
AsymmetricAlgorithm, which survives every read IdentityServer
does.
- Add BouncyCastle.Cryptography 2.6.2 to src/Yavsc.Org/Yavsc.Org.csproj
and the matching PackageVersion in Directory.Packages props.
- Wrap the loader in a try/catch that prints the full managed
stack to stderr on failure, so future PEM-format issues surface
in journalctl instead of being hidden behind SIGABRT.
/signin only renders the local-account sign-in form on Yavsc.Org;
new accounts live at /Account/Register. Update RegisterUrl in
LoginPageViewModel and the matching test accordingly.
The Yavsc.Org sign-in page and the password-reset page are the
canonical entry points for new users and locked-out users; expose
both from PostIt's LoginPage by deriving their URLs from the
configured Authentication.Authority.
* Add RegisterUrl, ForgotPasswordUrl, HasXxxUrl, ConfigMissing and
ConfigMissingMessage to LoginPageViewModel.
* LoginPage loads settings eagerly in the VM ctor so the URLs are
populated when XAML bindings first fire.
* Two new buttons (Register a new account, Forgot password?) bind to
HasXxxUrl via IsEnabled and fall back to Process.Start on click.
* A yellow banner surfaces when Authentication.Authority is empty,
pointing the user at ~/.config/PostIt/postit-settings.json.
Also drop the duplicated OIDC login logic from LoginPage.axaml.cs:
the page now drives Login through LoginPageViewModel.LoginAsync and
DataContext is auto-attached when HomePage pushes the page without
a VM.
Tests cover the happy-path OIDC flow, URL derivation, and the
ConfigMissing flag.
Add a stubbed OIDC authority (discovery, jwks, /connect/token,
/connect/userinfo) and a fake IBrowser, then cover the full
authorization-code + PKCE flow in LoginPageViewModelTests.
The new LoginPageViewModel(Settings, Func<IBrowser?>) constructor
plus the BrowserFactoryOverride property keep production wiring
unchanged: the existing parameterless ctor and the platform
projects' Platform.CreateBrowser still drive runtime.
Add ActivePageAny(ViewContext, IEnumerable<string>) so a dropdown
toggle gets the active class + aria-current="page" whenever any of
its children is the current route. Apply it to the Plateforme,
Administration, and account menu toggles.
Apply PageHelpers.ActivePage to all 13 <a class="dropdown-item">
entries across the Plateforme, Administration, and account
dropdown menus so users see which section they're in. The
Logout entry matches Account/Logout specifically to avoid
colliding with the Register/Signin entries on the same Account
controller.
Add PageHelpers.ActivePage extension and apply it to top-level nav
items and the Account/Register + Account/Signin items in _LoginPartial,
so the current route gets the active class and aria-current="page"
for accessibility.
The previous commit's table incorrectly stated that
appsettings-org.Development.json is committed; it is in fact
matched by .gitignore (appsettings-*.*.json), so each developer
generates their own from the template documented here. Fix the
table and clarify the role.
The localhoist typo that lived in the previously-shown blob is
not versioned, so it does not propagate via git.
The Yavsc.Org service reads appsettings-org.json at runtime, but the
contrib/Makefile renames that file to appsettings-org-dist.json right
before deploying to $(BASEAPPDIR), so first-time operators have to
copy the dist variant back to appsettings-org.json on the server and
fill in their actual values. None of that was documented; this commit
adds a Fichiers de configuration d'Yavsc.Org section under Paramétrage.
The section also notes that Site.ExternalUrl is now consumed by the
IdentityServer EF seed (added in the previous PostIt PKCE commit) to
authorize a RedirectUri for the 'postit' OIDC client, so PostIt can
be embedded in a Yavsc.Org web page without redirect_uri mismatch.
Side note: the appsettings-org.Development.json template points at
'https://localhoist:5001' which looks like a typo for 'localhost'.
Flagged in the README so it doesn't get copy-pasted into a new
environment as-is.
The previous commit set Platform.CreateBrowser to null on the desktop
side, so LoginAsync would still fail with 'No browser is available'.
Close that loop with an explicit desktop bootstrap.
PostIt.Desktop/PlatformBootstrap.cs mirrors the Android side: it
populates Platform.DefaultRedirectUri and Platform.CreateBrowser
once at startup. Program.Main calls EnsureInitialized before
BuildAvaloniaApp so the LoginPageViewModel sees a working browser
before any login attempt.
The Yavsc.Org seed now reads Site:ExternalUrl from configuration so
the RedirectUri list for the PostIt client follows the same setting
as the rest of the application (same value used in
Administration/ClientController, AccountController, etc.). Without
this, an embedded 'launch PostIt from a Yavsc.Org page' scenario
would be rejected by IdentityServer (redirect_uri mismatch).
BuildPostItRedirectUris is a small helper that yields the constant
PostItRedirectUris (loopback + Android custom scheme) followed by
Site:ExternalUrl when set. Both SeedNewPostItClient (fresh db) and
MigratePostItClientToPublic (existing db) consume it. The legacy
cleanup block (which used to remove https://yavsc.pschneider.fr/
and yavsc://callback) is dropped: Site:ExternalUrl is now the
canonical way to authorise that path and may legitimately equal
that value.
The earlier commit removed the client_secret and wired
MainActivity.OnNewIntent to AndroidOidcCallbackSink, but
IdentityModel.OidcClient.LoginAsync still had no IBrowser to drive
the user-agent half of the flow. Without it, the desktop / browser
projects continue to fail at login with 'No browser is available'.
Android now plugs in Chrome Custom Tabs:
* PostIt.Android/Services/AndroidSystemBrowser.cs implements
IBrowser.InvokeAsync using CustomTabsIntent.LaunchUrl and waits
for MainActivity.AndroidOidcCallbackSink to deliver the deep-link
Intent (android://postit-signin?code=...&state=...).
* PostIt/Services/Platform.cs is a tiny static indirection the
shared library uses to ask the running platform for an
IBrowser and the appropriate default RedirectUri, without
referencing any UI framework from the shared assembly.
* LoginPageViewModel reads Platform.DefaultRedirectUri and
Platform.CreateBrowser().Invoke() before calling LoginAsync.
* PostIt.Android/PlatformBootstrap.cs wires the Android side at
startup, and MainActivity.OnCreate calls EnsureInitialized().
* Xamarin.AndroidX.Browser 1.8.0 added to the central package
versions so CustomTabsIntent resolves.
PostIt is a desktop/mobile app talking to Yavsc.Org
(https://yavsc.pschneider.fr) as an OIDC identity provider. The
previous grant used the client_credentials flow with a client_secret
embedded in postit-settings.json: this was both insecure (secret
travels with the binary) and inappropriate for an interactive app
(token had no user identity, so the API could not scope or audit).
The new flow is Authorization Code + PKCE:
* PostIt client (Settings/AuthenticationSettings.cs): the
ClientSecret property is removed; GetOidcClientOptions now drops
the secret and accepts an optional IBrowser supplied per-platform.
* Settings.cs: new AndroidRedirectUri constant ('android://postit-signin')
that the Android app uses; RedirectUri is no longer hard-coded in
MainViewModel.
* MainViewModel.cs: the manual discovery + client_credentials POST is
replaced with OidcClient.LoginAsync (Authorization Code + PKCE).
* Settings sample: Authority points at the real Yavsc.Org OP, not at
a non-existent Keycloak-style realm path.
* Yavsc.Org/Extensions/HostingExtensions.cs: the 'postit' client seed
is now idempotent (MigratePostItClientToPublic) and detects
legacy state on existing ConfigurationDb rows - flips
RequireClientSecret=false, RequirePkce=true, drops any ClientSecret
row, and replaces the legacy RedirectUris
(https://yavsc.pschneider.fr/, yavsc://callback) with the current
set (http://127.0.0.1:7890/, android://postit-signin).
PostIt.Android:
* MainActivity: explicit Name attribute so the activity alias can
target a stable component; LaunchMode.SingleTask so the existing
instance receives the deep-link Intent; OnNewIntent forwards the
callback URI through AndroidOidcCallbackSink.
* AndroidManifest.xml: activity-alias PostIt.Android.OidcCallbackActivity
exposing scheme=android host=postit-signin to Android, so the OP
redirect lands back in the running PostIt instance.
The IdentityModel.OidcClient.Browser.SystemBrowser package and a
thin AndroidSystemBrowser implementation are added in a follow-up so
OidcClient.LoginAsync can actually drive Chrome Custom Tabs and
consume AndroidOidcCallbackSink.
