- UnifiedQueryPanel: fix JS operator precedence — .replace(' ','T') was
called on '.000Z' suffix instead of concatenated string, resulting in
'2026-06-27 12:46:28.000Z' (space not replaced) → ES 502
- normalizeTime: add space→T fallback for backward compat
- SyntaxHighlightInput: fix z-index layering (textarea z=2 was covering
pre z=1, making highlighted text invisible). Move bg/border to parent,
textarea bg→transparent, pre above textarea
Frontend may send dates without milliseconds (e.g. 2026-06-27T09:09:17Z),
which ES 7.2.0 strict_date_optional_time rejects. Backend now detects missing
milliseconds and inserts .000 before timezone suffix.
- ES query 502 fix: remove +00:00 conversion, use native .SSSZ format
(ES 7.2.0 date_time = strict_date_optional_time only, rejects +00:00/epoch)
- parseLogTime: use time.RFC3339Nano for fractional seconds
- new API GET /log-datasources/indices to list ES indices via proxy
- LogDatasourceDialog: add '获取索引' button + Select dropdown for ES
- LogDatasourcePage: always show demo sources alongside real ones
