From f7c182c5f7c45f8d512f4c8f546464b5c960d59b Mon Sep 17 00:00:00 2001 From: Kpa-clawbot Date: Tue, 31 Mar 2026 22:39:16 -0700 Subject: [PATCH] =?UTF-8?q?fix:=20packets=20page=20crash=20on=20mobile=20?= =?UTF-8?q?=E2=80=94=20time=20filter=20default=20and=20limit=20cap=20(#340?= =?UTF-8?q?)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes #326 — the packets page crashes mobile browsers (iOS Safari, Edge) by loading 50K+ packets when no time filter is persisted in localStorage. ## Root Cause Two problems in public/packets.js: ### Bug 1: savedTimeWindowMin defaults to 0 instead of 15 localStorage.getItem('meshcore-time-window') returns ull when never set. Number(null) = 0. The guard checked < 0 but not <= 0, so savedTimeWindowMin = 0 meant "All time" — fetching all 50K+ packets. **Fix:** Changed < 0 to <= 0 in both the initialization guard (line 30) and the change handler (line 758). ### Bug 2: No mobile protection against large packet loads Even with valid large time windows, mobile browsers crash under the weight of thousands of DOM rows and packet data (~1.4 GB WebKit memory limit). **Fix:** - Detect mobile viewport: window.innerWidth <= 768 - Cap limit at 1000 on mobile (vs 50000 on desktop) - Disable 6h/12h/24h options and hide "All time" on mobile - Reset persisted windows >3h to 15 min on mobile ## Testing Added 9 unit tests in est-frontend-helpers.js covering: - savedTimeWindowMin defaults to 15 when localStorage returns null - savedTimeWindowMin defaults to 15 when localStorage returns "0" - Valid values (60) are preserved - Negative and NaN values default to 15 - PACKET_LIMIT is 1000 on mobile, 50000 on desktop - Mobile caps large time windows (1440 → 15) but allows 180 All 218 frontend helper tests pass. Packet filter (62) and aging (29) tests also pass. ## Changes | File | Change | |------|--------| | public/packets.js | Fix <= 0 guard, add mobile detection, cap limit, restrict time options | | public/index.html | Cache buster bump | | est-frontend-helpers.js | 9 new regression tests for time window defaults and mobile caps | --------- Co-authored-by: Kpa-clawbot <259247574+Kpa-clawbot@users.noreply.github.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- public/index.html | 59 +++++++++---------- public/packets.js | 17 +++--- test-e2e-playwright.js | 25 ++++++-- test-frontend-helpers.js | 120 +++++++++++++++++++++++++++++++++++++++ 4 files changed, 178 insertions(+), 43 deletions(-) diff --git a/public/index.html b/public/index.html index eccef48c..eefbfa85 100644 --- a/public/index.html +++ b/public/index.html @@ -22,9 +22,9 @@ - - - + + + @@ -81,33 +81,30 @@
