From 08561033aecaee508ae60ad5d9c546f16a4dd7f2 Mon Sep 17 00:00:00 2001 From: vasilito Date: Sat, 20 Jun 2026 22:00:05 +0300 Subject: [PATCH] =?UTF-8?q?redbear-power:=20v1.17=20=E2=80=94=20Sort=20mod?= =?UTF-8?q?es=20in=20Process=20tab=20(closes=20v1.13=20forward=20work)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the v1.13 §37.6 forward-work item. Process tab now supports sorting by RSS, CPU%, PID, or Name — cycle with hotkey 'o'. Implementation summary: - New SortMode enum: Rss (default) / Cpu / Pid / Name - SortMode::next() cycles through all 4 modes - SortMode::sort(&mut Vec) reorders in place - ProcInfo::read_sorted(sort_mode) — read with custom sort - ProcInfo::read_with_cpu_pct_sorted(prev, dt, num_cpus, sort_mode) — re-sorts at end because CPU% may change rank - App.process_sort: SortMode field - 13-tick refresh uses sorted variant - Hotkey 'o' cycles sort mode (with status flash) - Header line shows 'sort: (press o to cycle)' - 6 new unit tests (default + cycle + 4 sort modes) Restored v1.16 changes (prior session left them partial): - NetInfo::rx_kbps + tx_kbps fields + init - NetInfo::read_with_throughput(prev, dt_secs) - App::prev_net field - 7-tick refresh uses read_with_throughput - render_network_panel RX/TX lines show '{X} KiB/s' - 3 network throughput unit tests 58/58 tests pass (5 bench + 12 sensor + 10 network + 12 storage + 19 process).
