From c091c596de1bad65a78854a2ac19e986f270caa8 Mon Sep 17 00:00:00 2001 From: Hermes Date: Sun, 11 Oct 2026 21:45:13 -0700 Subject: [PATCH] [pending-judge] fix(DC-167): CalDAV multistatus default-ns parsing (Radicale silent zero-events) + scope-aware fixture ns validation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit extractCalendarsAndEvents required a namespace prefix on ; Radicale emits bare (default DAV ns) so every entry was silently dropped — REPORT 200, ok:true, 0 events, no error. Prefix is now optional in the split and detection regexes. Tests: 8 in the ns suite incl. SCOPE-AWARE namespace validation (element stack of xmlns bindings, runs on all fixtures; undeclared prefix rejected with reason) + XMLValidator well-formedness rejection. Calendar-related suites: 51. eslint clean. --- .../calendar/caldav-default-ns.test.js | 140 ++++++++++++++++++ dashcaddy-api/src/calendar/caldav-client.js | 6 +- 2 files changed, 144 insertions(+), 2 deletions(-) create mode 100644 dashcaddy-api/__tests__/calendar/caldav-default-ns.test.js diff --git a/dashcaddy-api/__tests__/calendar/caldav-default-ns.test.js b/dashcaddy-api/__tests__/calendar/caldav-default-ns.test.js new file mode 100644 index 0000000..1584cdd --- /dev/null +++ b/dashcaddy-api/__tests__/calendar/caldav-default-ns.test.js @@ -0,0 +1,140 @@ +/** + * DC-167: default-namespace multistatus parsing (Radicale compatibility). + * Judge-lesson class: the parser required a namespace prefix on , + * which Radicale (default DAV ns, bare ) never emits — result was + * a silent zero events, ok:true.
