feat(jev): allow arbitrary HTTPS decision endpoints (carry #6384) - #6731
Merged
Merged
Conversation
…ters Review follow-up on #6384: - Reject URLs whose raw text carries an empty query, fragment, or userinfo delimiter; WHATWG URL drops those, so the parsed-field check missed them. - Send an arbitrary HTTPS decision path exactly as configured (a trailing slash is significant); /systemone keeps its trailing-slash normalization. Discovery reports the same URL. - Drop the runtime refusal of non-key authMode values. The decision request only ever carries the row's own apiKey, so the refusal protected nothing and made rows that the dashboard and save validation accept unusable at runtime. Cover oauth/local/forward rows sending only their own key.
…check URL strips tab, CR and LF before parsing, so https:<TAB>//@host evaded the raw empty-userinfo check. Refuse any C0 control or DEL in the configured URL, and cover the validation and runtime send boundaries.
src/ is not linted for no-control-regex; src/protocols/dto.ts uses the same expression unsuppressed.

Reject control characters before trimming the configured URL.
If baseUrl ends in a newline, Line 16 removes it before Line 18 checks for C0 characters. jevDecisionEndpointUrl also trims the value before src/combos/jev.ts validates it. The configured URL is therefore accepted and sent instead of refused. Check the original baseUrl before normalization, and keep that check on the runtime path. Add a leading- or trailing-newline regression case alongside the existing embedded-control cases. The PR objective requires raw URL text to be checked before parsing.

Merge b1e1735 additively after the specified dev c0f8165. The four newer upstream commits are 18a8cda (lidge-jun#6731), 13348ce (lidge-jun#6729), 8d30945 (lidge-jun#6713) and b1e1735 (lidge-jun#6732); their history is preserved unchanged. The only content conflict is src/combos/jev.ts, where lidge-jun#6731 edited the endpoint resolver that the P0 exchange extraction moved to src/combos/jev-service-exchange.ts. This merge keeps the P0 side of jev.ts byte for byte. The exchange resolver still applies the pre-lidge-jun#6731 trailing-slash normalization after this commit; carrying the shared endpoint authority into it is a separate follow-up commit.

…esolver lidge-jun#6731 (18a8cda) made jevDecisionEndpointUrl the authority for the decision destination: an arbitrary HTTPS path is sent exactly as configured, and only a /systemone path keeps its trailing-slash normalization. Management and validation already use it; the extracted exchange resolver still stripped every trailing slash, so a row accepted by validation and shown by discovery was posted to a different URL. The exchange now takes the destination from jevDecisionEndpointUrl and admits it through isSystemOneEndpoint, with no local normalization. Add regressions to the existing exchange test: exact HTTPS paths and trailing slashes, /systemone normalization, query, fragment, userinfo, control-character and admission refusals, and a request body that does not depend on the path. The same URLs go through the exchange and the route resolver. Note the URL contract in the structure document.

Summary
Carries #6384 by @Loncaster with maintainer review fixes. An explicitly selected JEV decision provider was rejected unless its URL ended in
/systemone, even when a compatible HTTPS service exposes the same decision contract at/v1/decisionsor another path. Ajev-decisionrow may now use any HTTPS path; plain HTTP still requires a local/systemoneendpoint plus the existing explicit private-network permission. The canonicaljev/TypeSafe path is unchanged.The author's change (e70f125) is preserved. Review follow-ups on top of it:
https://h/x?,https://h/x#,https://@h/x,https://:@h/xandhttps:<TAB>//@h/xtherefore passed. The raw text is now checked for C0/DEL characters,?/#and an@in the authority before parsing.https://h/v1/decisions/was sent to/v1/decisions. Arbitrary HTTPS paths are sent exactly as configured; a/systemonepath keeps its historical trailing-slash normalization. Discovery reports the same URL.keyauthModevalues at runtime while dashboard and save validation accepted them, so such rows saved successfully and then never sent. The decision request only ever carries the row's ownapiKeyas a Bearer header (TypeSafe environment references and foreign keychain entries are still refused), so the refusal protected nothing; it is removed and covered foroauth/local/forwardrows.Redirect refusal, DNS-validated/pinned HTTPS transport, private-network permission, request/response bounds, timeout and cancellation are unchanged. Known and out of scope: a provider row literally named
jevthat is retargeted still uses the canonical TypeSafe URL (existing documented behavior), and dashboard hint copy ingui/src/i18nstill mentions/systemone(no GUI change in this PR).Supersedes #6384.
