From c63b2fa00b37fcbcefa6b9a2c39fa61646e59f26 Mon Sep 17 00:00:00 2001 From: colombod Date: Mon, 17 Aug 2026 00:27:53 +0000 Subject: [PATCH 1/3] fix(upload): time-consistent replay to prevent stranded delegated sessions run_upload previously fed events whole-session, parent-first, with no ordering relative to the server's concurrent per-session drain -- so a delegated sub-session (or its parent) could be left status=running when a cross-session reopen was processed after that node's own session:end. Feed events in true global timestamp order across the session-tree closure (lazy heapq.merge over per-line generators -- O(sessions) memory, never loads a file whole), and pace by the events' own inter-event gaps capped at max_gap_s (default 2.0s) so a spawned sub-session drains before its parent resumes. No server change and no /status/drain signal -- ordering is derived purely from the recorded timestamps. Reuses the existing parse/build_payload/POST/retry/auth path verbatim; only the feed order + pacing + tracker triggers changed. Validated on an isolated server: child+parent completed 20/20; non-delegated upload unaffected; peak RSS flat (~41MB) uploading a 74.9MB single-session file; zero /status calls. 564 existing + 10 new tests green.
