# =============================================================
# OxiCloud — CalDAV calendar-query REPORT time-range regression
# =============================================================
# Regression pin for the time-range parser fix on
# fix/caldav-time-range-parser.
#
# Pre-fix: caldav_adapter.rs::parse_report used
# `DateTime::parse_from_rfc3339` on the `<C:time-range start="..."
# end="..."/>` attribute values. That parser expects
# `YYYY-MM-DDTHH:MM:SSZ` (dashes + colons). CalDAV clients send
# iCalendar DATE-TIME format (`YYYYMMDDTHHMMSSZ` — no separators)
# per RFC 4791 §9.9 / RFC 5545 §3.3.5. Result: parse silently
# failed, `time_range` was `None`, and the REPORT handler fell
# through to `list_events`, returning the ENTIRE calendar
# regardless of the requested window.
#
# Post-fix: `parse_caldav_datetime` accepts iCal DATE-TIME
# (the standard) with RFC 3339 as a defensive fallback. Time-
# range filters now actually filter.
#
# Test shape: create two events at 09:00 UTC and 15:00 UTC, then
# calendar-query REPORT with an iCal-DATE-TIME window covering
# only the 09:00 event. Assert the response contains the 09:00
# event's UID and does NOT contain the 15:00 event's UID.
