fix(import): converge on replay by checking existence before creating - #41
Conversation
A replay still aborted on the first duplicate role. Widening `is_conflict` cannot fix the remaining cases: the server answers a duplicate role or client with a bare 500 whose body carries nothing to tell it from a genuine failure, so any pattern matching it would also swallow real errors. A duplicate redirect URI is worse than an error — it returns 201 and stores a second row, so every replay grew the client's redirect list unnoticed. Read what the realm already has and skip it, instead of classifying the create error: realm, realm roles, clients, client roles, redirect URIs, post-logout redirects, web origins, users and their role assignments are all matched against the server's current state first. `is_conflict` stays as the fallback for the cases it does recognize and for the race between the read and the create. Skips keep being counted in `already_present` with a warning naming the entity, so a converging run stays distinguishable from one that did nothing. Adds the three list endpoints this needs to the client (redirects, post-logout redirects, web origins). Closes #27
📝 WalkthroughWalkthroughThe client adds methods to list client URI resources. Import replay now reads existing realms, roles, clients, URIs, and users before creation or assignment, records skipped matches, and limits fallback backfills to failed listings. ChangesImport convergence

reqwest 0.12 redirect policy Authorization header HTTP HTTPS official documentation
💡 Result:
In reqwest 0.12, the client follows a security-conscious redirect policy that automatically strips sensitive headers—including Authorization, Cookie, Proxy-Authorization, and WWW-Authenticate—when a redirect crosses an origin boundary [1][2]. An origin change is defined by a difference in the host, port, or scheme (e.g., redirecting from HTTPS to HTTP) [2][3]. If a redirect occurs between different hosts, ports, or schemes, these headers are removed from the subsequent request to prevent potential credential leakage to third-party services [2][3]. Because this behavior is hardcoded in the client's internal redirect handling, there is no built-in option to keep the Authorization header during cross-origin redirects [4]. If your application requires maintaining these headers across redirects (for example, when redirecting to a trusted CDN), the recommended approach is to disable automatic redirects using Policy::none and implement custom redirect logic [5][6][4]. To handle this manually, you can perform the initial request with redirect following disabled, check the response status for a redirection code (e.g., 301, 302, 307, 308), extract the Location header, and issue a new request manually with the desired headers intact [5][4]. Example of manual redirect handling: let client = Client::builder.redirect(redirect::Policy::none).build?; let mut res = client.get("https://example.com").send.await?; while res.status.is_redirection { if let Some(location) = res.headers.get(header::LOCATION) { let next_url = location.to_str?; res = client.get(next_url).send.await?; } else { break; } }

Require encrypted transport for bearer-authenticated requests.
FerriskeyClient::new accepts http:// URLs, and get_json sends the bearer token to the configured URL. Reject non-loopback cleartext URLs, or require an explicit development-only exception. Reqwest removes Authorization on cross-origin redirects, so no separate redirect change is required.

Refresh role IDs after a create conflict.
A concurrent importer can create a role after the initial listing. This import then records the create conflict as already_present, but it has no ID for that role. These guards prevent the required refresh. Realm-role assignment is skipped, and client-role assignment returns UnresolvedClientRole.

Do not treat a failed redirect listing as an empty redirect list.
When list_client_redirects fails during a replay, this returns an empty set and the redirect loop posts every configured URI. The redirect endpoint accepts an existing value with 201 and stores a second row, so is_conflict cannot stop the duplicate. Return the listing failure for redirects, or skip that client’s redirect creation when the list is unavailable.

Bug
Replaying an import still aborted on the first duplicate role, even after #35 widened
is_conflictto the500 unique constraintshape cited in the issue.Why
is_conflictcannot be widened furtherProbed each create endpoint against a running FerrisKey 0.7.0 with an already-imported realm. What a duplicate looks like is not uniform:
409 E_CONFLICT500{"message":"Internal Server Error: Internal server error"}500{"message":"Internal Server Error: Failed to create client"}500generic, same as realm role201— stores a second row400"this origin is already registered for the client"400"Email already exists in this realm"Those
500bodies carry nothing that separates "already exists" from a genuine server failure, so any pattern matching them would also swallow real errors — which is exactly why #35 stopped there and left the issue open. And the redirect case is not an error to classify: the server accepts the duplicate, so every replay silently grew the client's redirect list.Fix
Read the realm's current state and skip what it already has, instead of deducing it from the create error. Applied to realm, realm roles, clients, client roles, redirect URIs, post-logout redirects, web origins, users, and user role assignments — matched on name for entities, on value for URIs and origins.
is_conflictis kept, unchanged, as the fallback for the cases it does recognize and for the race between the read and the create.already_presentwith a warning naming the entity, so a converging run stays distinguishable from one that did nothing (the issue's second ask).Client-side, this needs three read endpoints that were missing:
list_client_redirects,list_client_post_logout_redirects,list_client_web_origins(all three exist server-side, confirmed live).Cost
One extra GET per entity kind, plus one per user, on top of the creates. Deliberate: correctness of the replay is what the file's header promises, and the alternative is guessing from an error body that carries no information.
Verification
Against a local FerrisKey server, using
examples/realm.yamland a second blueprint exercising client roles and web origins:already_present: 0(unchanged behaviour);already_present: 12, nothing created, no error, one warning per skipped entity;viewerrole server-side, replayed →roles created: 1, everything else skipped;201above was causing);Test realms deleted afterwards.
