From f0c7d82f5b21d7ee104cdc7f22a291945e9340de Mon Sep 17 00:00:00 2001 From: Josh de Leeuw Date: Mon, 30 Mar 2026 16:21:17 -0400 Subject: [PATCH 01/19] fix: increase memory limit for data upload functions to 512MiB The apiData and apiBase64 functions were running with the default 256MiB memory limit, which is insufficient for the Node.js runtime + Firebase SDK baseline (~150MiB) plus multiple copies of the data payload held in memory during upload. This caused OOM kills that returned 503 responses without CORS headers, leading users to report CORS errors (see #102).

If the function crashes, the data survives in the pending-data/ prefix and can be recovered. On successful OSF upload (or successful queue), the pending copy is cleaned up.

A light text indicator near the header badges shows retry count and next retry time instead — no alarm for things the system handles. - The full alert panel (FailedUploadsPanel) only appears when uploads have exhausted all retries and the researcher needs to download. - Failure reasons get their own REASON column instead of tiny text under the filename. - Replace ATTEMPTS column with AUTO-CLEANUP (time until data expires). - Add UploadsResolvedNotice: brief success confirmation when all queued uploads complete, so the panel doesn't just vanish. - Remove error log mixing from the queue table (ErrorPanel handles those separately).

Since writeLog() is awaited inside apiData before the response is sent, the log document is guaranteed to exist by the time saveData() returns.
