fix(ui): test authenticated service connections before saving by deniial00 · Pull Request #1522 · opengeos/RustGIS

deniial00 · 2026-11-06T22:07:00Z

Summary

A new WMTS connection with Basic authentication could only be saved: Test stayed disabled even after entering credentials and consenting to unencrypted HTTP. New authenticated web-service forms can now test the entered login before saving.

The test owns a disposable, origin-bound request binding and never borrows a saved connection's login or changes its definition. Form edits, cancellation and project changes revoke the temporary binding and discard late results. Existing HTTP consent and transport redirect protections remain in force; edited saved service definitions retain their existing save-before-test guard. The public command contract is unchanged.

Passwords and keys bypass command parameters/history and are cleared from the form when the temporary test starts. Saving a session login afterward requires entering the secret and HTTP consent again. The user guide explains this workflow.

No dependency added. No external project's code was followed.

Testing

cargo xtask ci passed: formatting, workspace Clippy, workspace tests and layer checks.
cargo build --target wasm32-unknown-unknown -p rustgis-web passed. No browser runtime exercised.
pre-commit run --all-files passed.
Targeted runs passed: 12 service-login UI integration tests, 11 connection-dialog unit tests and 10 tile-login tests. Earlier engine service-login run passed 45 tests. Coverage includes Basic/header credentials, saved-login isolation, HTTP consent, cache isolation/revocation, late results, probe-failure secret clearing, replacement-dialog feedback, echoed status and short-response history redaction.
Rebuilt and ran the actual ui_shot example before and after. A controlled local WMTS endpoint verified the received Basic credential: correct credentials produced WMTS: 1 layers, wrong credentials produced HTTP 401, and denied HTTP consent sent no request. The connection remained unsaved.
Followup reviewed with review-loop: 3 fresh-reviewer rounds before pushing; 1 security finding fixed, 0 declined. Verdicts: CHANGES, APPROVE, APPROVE. Four additional PR-review fixes cover the macOS test socket mode, early credential clearing, replacement-dialog feedback and echoed credential redaction.
Before merging upstream, followup cargo xtask ci, WebAssembly build and pre-commit run --all-files passed. After merging upstream, the WebAssembly build and pre-commit passed; cargo xtask ci failed in geolibre_tools_run_on_layers_and_add_their_outputs because the installed GeoLibre 1.7.1 runner's error lacks the expected Slope: prefix. It failed the same way on unmodified upstream c506aa10 at the time; after the later upstream merges it passes, and full cargo xtask ci passed on the final head.
After merging upstream, a fresh actual ui_shot against a controlled local WMTS endpoint verified authentication and displayed both raw-password and wire-Basic title echoes as [redacted]. Short plaintext/XML response history regressions failed before the fix and passed afterward.
Second followup: explicit service-login GET bindings take precedence over a same-origin S3 session signer. Two tiles regressions, 12 service-login UI integration tests, 11 connection-dialog unit tests and scoped Clippy passed. A real UI/local WMTS smoke with a colliding S3 session login received only the service credential. Three further independent reviews approved (one quality-only wording point deferred). The WebAssembly build and pre-commit passed; local full CI again stopped at that GeoLibre error-prefix assertion (passes on the final head, see below).
Third followup: after any login-bearing hop, a native GET refusal is status-only and a rejected redirect destination is reported without its address, so a delayed response after the test is abandoned and its login revoked cannot store an echoed credential in diagnostics. Loopback regressions cover both cases with anonymous controls that keep their detail; the rejected-redirect one failed before its fix (credential in the retained diagnostic) and passes after. An abandoned test clears only its own Testing status. The session log now gives a response's size once (a large entry logged 41 characters as 29; regression failed before, passes after).
Merged upstream main twice and resolved conflicts in cache.rs and connectionui.rs, keeping upstream's redirect reach checks and message sanitising alongside this PR's redaction. On the final head, cargo xtask ci passed (including the GeoLibre test that failed locally before), as did the WebAssembly build and pre-commit run --all-files.
Third followup reviewed with review-loop: 3 fresh-reviewer rounds; 1 finding fixed (response size), 1 declined as out of scope (HEAD redirect redaction, unchanged from base and unused by Test), nits left for the release quality pass. Verdicts: CHANGES, APPROVE, APPROVE. An earlier pre-round review found the rejected-redirect leak, fixed above.

UI evidence

Before: fresh baseline build, authenticated form with HTTP consent checked and Test disabled.

After: entered authenticated form, Test available before saving.

Successful authenticated capabilities response:

Wrong credentials:

HTTP consent denied; no request reached the endpoint:

The after images were rendered before a behavior-preserving Clippy guard simplification; full CI and the WebAssembly build passed afterward.

Summary by CodeRabbit

New Features
- Test a new web-service connection before saving it with a Basic password or header API key.
- Testing an HTTP address requires confirmation before credentials are sent unencrypted.
Changes
- Credentials and HTTP confirmation are cleared when a test starts. Tests do not save the connection or retain its login.
- Save address or login changes to an existing service connection before testing it.
- Test results mask echoed credentials, and command history records response sizes rather than response bodies.
- Response details and redirect errors are limited when requests involve credentials.
Documentation
- Updated the Named Connections guide with the testing flow and security requirements.

Walkthrough

The engine adds temporary, origin-bound login probes for unsaved service connections. The UI uses typed credentials to test new connections and retains the temporary login through response parsing. Shared GET preparation handles explicit service logins before S3 signing. Response logging and user documentation are also updated.

Changes: Temporary service-login testing

Layer / File(s)	Summary
Temporary probe binding and validation `crates/engine/src/service_logins.rs`, `crates/engine/src/tests/service_logins.rs`	A temporary probe validates the unsaved connection and URL, activates an origin-bound login, and returns a guard that deactivates the binding when dropped. Tests cover validation, isolation, HTTP consent, and cache behavior.
Service-login GET preparation `crates/tiles/src/cache.rs`, `apps/rustgis-web/src/web.rs`	Shared GET preparation unwraps explicit service-login URLs without S3 headers and delegates other URLs to S3 preparation. Native and browser GET paths use this preparation; tests cover revocation and redirects.
Unsaved service test lifecycle `crates/ui-egui/src/connectionui.rs`, `crates/ui-egui/tests/service_logins/mod.rs`	Unsaved authenticated tests use a temporary probe and omit typed credentials from command parameters. The UI retains the probe through response parsing and clears pending tests when the form, project, or dialog changes. Tests cover authentication, validation, credential redaction, and stale results.
Response logging and documentation `crates/engine/src/project_log.rs`, `crates/engine/src/tests.rs`, `docs/user-guide/data.md`	String values under an object field named `answer` are logged as response-length markers. The guide explains unsaved testing, HTTP confirmation, credential clearing, and the save requirement for changes to existing connections.

Merge Risk: Low · up to 6f8a3

Authenticated web-service connections can now be tested before saving, and the earlier credential-leak concerns in refusal handling are addressed. One minor gap remains: native HEAD and POST requests do not give an explicit service login precedence over a same-origin S3 signer. That affects only a narrow configuration and was already the case before this PR. Consider fixing it, but it should not block merging.

+                Ok((stream, _)) => break stream,


Possible test failure on macOS/BSD (medium confidence). The listener is set non-blocking at line 186. On BSD-derived systems (macOS), an accepted socket inherits O_NONBLOCK, so the stream.read(...) call in the request loop can return WouldBlock before the client's request arrives. That unwrap() then panics the server thread and the test fails. Linux doesn't inherit the flag, so Linux CI won't catch it; the nightly macOS run would.

Suggested fix: clear the flag on the accepted stream.

Suggested change

Ok((stream, _)) => break stream,

Ok((stream, _)) => {

stream.set_nonblocking(false).unwrap();

break stream;

}

Confidence: medium (about 70%); I haven't run this on macOS.

Fixed in 685f7e2: accepted fixture sockets are explicitly blocking before request reads.

    }
    p["probe"] = json!(true);
    let result = app.run("connection.test", p);


Typed secret stays in the form when the anonymous probe fails (low severity, high confidence). clear_secrets runs only for non-temporary tests, and the temporary branch clears later. If connection.test returns Err, or the response has no fetch ("Nothing to test"), start_test returns early with the password or API key still in app.ui.connection. The PR's docs and comments say the secret is cleared "when the temporary test starts", so this contradicts them.

Nothing is sent on those paths, so the impact is limited to secret hygiene and the stated guarantee. The fix is to take a copy of the secret, and of allow_insecure, before the probe, and clear the form right after it on every service path. Alternatively, clear it in the two early-return arms when temporary is true.

Fixed in 685f7e2: temporary-form secrets are cleared on probe failure and missing-fetch exits.

+        // and responses arriving after this drop recheck the binding and cannot reuse it.
+        logins::deactivate(&self.binding);


Performance: every authenticated Test teardown wipes the whole tile cache (medium confidence). logins::deactivate calls crate::cache::clear() when it removes a binding. That function keeps only Pending slots and then clears the sources, sprites, PMTiles, MBTiles, COG and warp caches. So each time an unsaved authenticated Test is dropped, after its result, on edit, on cancel, or when a project changes, every public basemap tile in the open map is evicted and re-downloaded.

The existing saved-login revocation has the same effect, but this PR adds a new, frequent trigger. Scoping the clear to entries bound to this login, or deferring it to the next frame, would avoid it. This is a performance concern, not a correctness one. The Drop ordering and lock release are fine.

Left for the release quality pass: scoped cache eviction is a performance redesign beyond the existing safe login-revocation mechanism (reviewed at e71e60e).

Quality (may wait for the release quality pass): the two new messages are private consts inside temporary_probe, and this match repeats their literal text. The two copies can drift apart silently. Moving them to pub const next to the other messages in service_logins.rs would let this match use web::BAD_DEFINITION and web::BAD_ADDRESS, like the arms above it.

Left for the release quality pass: consolidating the duplicated message literals is a maintenance quality change (reviewed at e71e60e).

Code review

Prior review threads on this PR: none, so no earlier concerns were skipped.

Checked: the new temporary-probe path in service_logins.rs (validation order, origin and consent checks, guard lifetime), the connection-dialog test flow (start_test, poll, the Save path, the edit reset), the tile-logins revocation and cache-clear behaviour, and the new engine and UI tests against the PR's claims. I found no crash path, no silent data loss, and no credential leak into command parameters, history or saved connections.

Bugs

Typed secret stays in the form when the anonymous probe fails (crates/ui-egui/src/connectionui.rs:396). The early returns on probe error or missing fetch skip the temporary-path clear, so the password or key remains in the form, contrary to the docs. Nothing is sent. Low severity, high confidence.
Possible test failure on macOS/BSD (crates/ui-egui/tests/service_logins/mod.rs:198). An accepted socket inherits the listener's non-blocking flag on BSD-derived systems, so the request read can hit WouldBlock and panic. Linux CI would not catch this. Medium confidence (about 70%), not run on macOS.

Security

No findings.

Performance

Each authenticated Test teardown evicts the whole tile cache (crates/engine/src/service_logins.rs:108). logins::deactivate calls cache::clear(), which drops every ready tile, style and sprite. Every unsaved authenticated Test that ends therefore re-downloads the basemap. Medium confidence.

Quality

Duplicated message literals (crates/ui-egui/src/connectionui.rs:100). The two new translated() arms repeat text from private consts in temporary_probe. Moving them to pub const would remove the drift risk. Left for the release quality pass.
Nits, also for the release quality pass: st.id.as_ref()?; in test_blocked (connectionui.rs:352) returns None, meaning "not blocked", which is easy to misread. The poll form comparison duplicates the reset already done on field change.

AGENTS.md

No violations found. The unwrap, unreachable and panic uses are in test code only, and the wasm-gated test is correctly cfg-guarded.

I posted four inline comments: three findings and one quality point marked .

Review of the summary-only quality points at e71e60e:

The st.id.as_ref()? readability suggestion is left for the release quality pass.
The additional form comparison protects programmatic changes as well as UI field edits; no behavior change is needed.
The docstring-coverage metric is a quality-only concern here and is left for the release quality pass; no required behavioral contract was identified as missing.

Test gap for the log leak in project_log.rs kept_error. The loop covers <Exception>, but that never echoes the secret, so the test passes without exercising the leak. It only asserts on entry.params, not on entry.error.

Add a ServiceExceptionReport case, and assert on the error as well:

] {

Also assert !entry.error.as_deref().unwrap_or_default().contains("web-widget-secret-sentinel") next to the existing params check. This test fails until the kept_error fix lands.

Covered in bda1c27 by a ServiceExceptionReport response that echoes the credential and checks the logged and displayed errors.

+                    } else if k == "answer"


Bug (medium-high confidence, about 85%): a typed temporary-login secret can reach the session log through an error. This comment is anchored here because kept_error (project_log.rs, line 129) is outside the diff.

kept_error redacts only with history::redacted_text and sql_secrets_removed. Neither consults the active logins, so logins::scrub never runs on this path. The UI scrubs the dialog text, and Session::notify goes through durable::generated_text, which does call logins::scrub. The log does not.

The gap is reachable from this PR. A test answer that is a ServiceExceptionReport makes ogc::parse return the service answered with an error: {text_of(root)} (up to 300 characters of the response). service::capabilities returns that unchanged via failed, and Session::run logs it through project_log::entry. A server that echoes the form's Basic password or key in its exception text therefore stores it in the log's error field. The existing test only sends <Exception>, which gives not a WMS…(<Exception>) and never echoes the secret, so it does not catch this.

The data guide's claim that the log keeps "response sizes rather than response bodies" is also wrong for error text.

Suggested fix: in kept_error, call crate::render::rustgis_tiles::logins::scrub(e) before the clip. Scrubbing first also means a secret cut at the clip boundary cannot survive. Regression test: see the comment on crates/ui-egui/tests/service_logins/mod.rs.

On the merged head, Session::run_command scrubs generated errors before command_epilogue records them. Added a real exception-response regression in bda1c27 to verify the log and dialog remain redacted.

Code review

Bugs

No separate bugs found. I checked the temporary branch of start_test, the stale-test check in poll, the dialog() cleanup, and the drop order of the revocation guard.

Security

A typed temporary-login secret can reach the session log through an error (medium-high confidence, about 85%). project_log::kept_error redacts with history::redacted_text only, and that never consults the active logins. A ServiceExceptionReport answer echoing the form's password or key makes ogc::parse return up to 300 characters of response text. service::capabilities passes that error through unchanged, so Session::run logs it raw. The UI dialog and notices are scrubbed, but the log is not. The new test only sends <Exception>, which never echoes the secret, so it misses this. Inline comments are on crates/engine/src/project_log.rs:424 (the fix belongs in kept_error, line 129, which is outside the diff) and crates/ui-egui/tests/service_logins/mod.rs:313 (a regression case to add).

Performance

No new issues. The earlier point that each temporary-test drop clears the whole tile cache still applies, and this PR makes it more frequent.

Quality

No new issues beyond earlier threads. The answer clip in project_log.rs applies to every command's answer string parameter, not only connection tests. The docs describe it only for connections.

AGENTS.md

docs/user-guide/data.md says the command log keeps "response sizes rather than response bodies". That is wrong for error text, which is the security finding above (medium confidence).
I could not run the tests or CI; this review is by reading the code only.

Earlier review threads: 7 checked, none re-posted. Four are addressed in this head: typed-secret clearing on the error paths, title redaction, the macOS non-blocking accept, and status preservation. Three are still open and were not re-raised: the whole-cache clear on deactivate, the duplicated message literals (quality pass), and the revocation-assertion nit.

    if !matches!(app.dialogs.open, Some("newConnection" | "editConnection")) {
+        if app.ui.connection.test.take().is_some() && app.dialogs.open.is_none() {


Stale "Testing…" status can survive under a replacement dialog (low–medium severity, about 50% confidence).

When a connection test is pending and another dialog opens (dialogs.open is Some(..)), this branch drops the test but keeps dialogs.info. start_test set that info to "Testing…", and nothing else clears it. Opening a dialog doesn't reset dialogs.info, so the replacement dialog can keep showing "Testing…" after the test has been abandoned.

The guard keeps replacement-owned status. That is right for dialogs.error, but the info here is the connection test's own status. Clearing dialogs.info only when it equals the test's "Testing…" text would fix this without touching the replacement's messages.

I haven't reproduced it in the UI. abandoned_probe_preserves_replacement_dialog_status sets only error, so it wouldn't catch this.

Fixed in 0275a50: dropping an abandoned connection test clears its stale Testing status while preserving a replacement dialog's own messages. The status is the translation captured when the test started, so a language change cannot leave it behind.

Code review

Bugs

Stale "Testing…" status under a replacement dialog (crates/ui-egui/src/connectionui.rs:613). When a pending test is dropped while another dialog is open, the info string "Testing…" is kept. It is the test's own status, not the replacement's, and nothing else clears it. Confidence about 50%. Posted inline.

No other new defects found. I checked these paths:

S3 signing vs. explicit login (cache::prepare_get, apps/rustgis-web/src/web.rs): the browser and native GET paths both apply the login header after the prepare_get change, and the S3 signing step no longer runs for login-bound URLs. This is the intended behaviour. login_address::bind only wraps http(s) origins, so a wrapped s3:// URL can't reach this branch.
Error logging: Session::run → run_command → durable::generated_text → logins::scrub runs while the probe login is still active, so echoed credentials are redacted before project_log::entry sees the error.
answer log redaction: kept_params' fallback short() path only sees already-clipped values, so the response body never reaches the log.
insecure flag: activate only checks it for http:// origins, so it does nothing for https.
Secret clearing and cancellation: the failure and missing-fetch paths clear the form secrets, and editing the form drops the pending test (st.test = None).

Security

None found beyond the above. Login values are kept out of command parameters and the log, and the temporary binding is revoked on drop.

Performance

No new findings. The earlier cache-eviction concern is still present, but I left it alone (see below).

Quality

No new findings. The duplicated message literals are an earlier concern, which I also left alone.

AGENTS.md

No violations found. Errors go through tl!, the new code avoids unwrap and panic, and the new documentation matches the behaviour.

Earlier review threads

I checked the 11 earlier threads against the code:

Fixed and verified, 7: the typed-secret clearing on probe failure, the macOS non-blocking socket, the redaction of echoed credentials, the replacement-dialog status, the S3 origin conflict, the logged ServiceExceptionReport case, and the ServiceExceptionReport test gap (now covered by the new test).
Left alone, 4: the cache-eviction performance concern, the duplicated message literals, the kept_error concern (its premise appears mitigated, see Bugs above, but the function itself still has no logins::scrub), and the lifecycle test coverage.

Re the latest review summary: the stale "Testing…" finding is fixed in 0275a50 (thread reply here). The CodeRabbit refusal finding is fixed in the same commit, and c764cbe extends that rule to rejected redirect destinations. b5cc1e2 fixes the session log reporting a large entry's response size incorrectly. Upstream main is merged with conflicts resolved; cargo xtask ci, the WebAssembly build and pre-commit pass on 6f8a399.

+        .connection
+        .test
+        .as_ref()
+        .is_some_and(|(_, _, context)| context.opened != app.session.opened || context.form != definition(&app.ui.connection));


Bug (about 75% confidence, not run): editing the typed password or key does not discard a pending temporary Test.

The stale check compares context.form with definition(&app.ui.connection). definition() covers kind, name, group, address, auth, user and key name, but not password or api_key. start_test clears those secrets when the probe starts, so after the user types a new key the snapshot still matches. The pending Test keeps its login, and its late result is shown for a key the user has since replaced.

This contradicts the PR description ("Form edits ... revoke the temporary binding and discard late results"). It also looks like it breaks the unsaved_authenticated_test_discards_late_results_after_edit_cancel_or_project "edit" case, which types into Key and then asserts test.is_none(). I could not run that test, so please run it to confirm.

Possible fix: record a non-secret fingerprint of the typed secret fields in TestContext, taken after clear_secrets, and compare it here as well. For example, hash (&st.password, &st.api_key) with DefaultHasher. Any new typed value then makes the test stale, and no raw credential is retained.

Not reproducible: any edit to the typed password or key sets changed (connectionui.rs:1012), and the form then drops the pending test (:1038–1040) before poll runs; the poll comparison is a second guard. unsaved_authenticated_test_discards_late_results_after_edit_cancel_or_project_change covers the Key edit and passes in CI on 6f8a399.

-            // endpoint is signed.
-            crate::logins::check(url)?;
-            let prepared = crate::s3::prepare(crate::logins::inner(url))?;
+            // Explicit service logins outrank implicit S3 endpoint signing.


Inconsistent precedence (about 55% confidence, pre-existing in the HEAD and POST paths). This change makes GET prefer an explicit login over S3 signing. The HEAD path (around cache.rs:2414) and the POST path (around cache.rs:2511) still call s3::prepare(logins::inner(url)) and then apply the login unconditionally. Where an explicit login and an S3 endpoint share an origin, those requests can still carry both the SigV4 headers and the login header, which is the collision this PR fixes for GET. The browser HEAD and POST paths in apps/rustgis-web/src/web.rs have the same pattern.

If HEAD and POST are meant to stay as they are, a short comment saying so would help. If not, they should use the same routing as prepare_get.

Pre-existing and outside this PR: HEAD and POST login handling is unchanged from base, and Test before Save only issues GET. Left for a follow-up issue.

Code review

Bugs

Editing the typed password or API key does not discard a pending temporary Test. poll's stale check compares definition(), which leaves out the secret fields, so the late result is still shown for a key the user has replaced. This contradicts the PR description and likely fails the "edit" case of unsaved_authenticated_test_discards_late_results_after_edit_cancel_or_project. I could not run that test. Confidence about 75%. (inline: crates/ui-egui/src/connectionui.rs:632)
The explicit-login-over-S3 fix covers GET only. HEAD and POST in cache.rs (around 2414 and 2511) and the browser paths in web.rs still sign and then apply the login, so both headers can still be sent. Confidence about 55%, and the pattern predates this PR. (inline: crates/tiles/src/cache.rs:2737)

Security

No new issues found. Temporary credentials stay out of command parameters, history and the session log. Redirects and HTTP consent are still enforced. Errors and summaries are scrubbed through logins::scrub.

Performance

Nothing new. The existing concern that logins::deactivate clears the whole tile cache is still open and was deferred by the author, so I left it alone.

Quality

Nothing new worth raising now. The duplicated message literals were already raised and deferred, so I left them alone.

AGENTS.md

No unwrap or panic was added to non-test code. Messages are wrapped in tl!. The new logic has tests for both the clean and the lossy cases. Nothing was added below L6 that depends on egui.
The redirect refusal message is replaced by a generic string when a login was carried. That is an acceptable tradeoff, but the diagnostic is less specific.

Earlier review threads: I reviewed 13 existing threads. Ten are fixed or resolved, and I did not re-raise them. Two open ones are deferred by the author: the cache-clear performance point and the duplicated literals. I left both alone. The "Testing…" status thread is addressed by the current poll code.
