From 2d7309cf4d9ef74963f2b6906fc817d7d4d91b3e Mon Sep 17 00:00:00 2001 From: lushan888 Date: Wed, 8 Jul 2026 22:24:43 +0800 Subject: [PATCH] feat: add cross-platform fallbacks for memory and load checks - check_memory_usage(): keep /proc/meminfo path on Linux, add psutil fallback, then os.sysconf as final fallback - check_load_average(): keep /proc/loadavg where available, add os.getloadavg() fallback for non-Linux Unix-like systems - Add test_health_check.py with 5 tests: memory fallback without /proc, psutil verification, /proc path, load fallback without /proc, /proc path - All tests pass on macOS (non-Linux) with fallback active - JSON and text output remain backward compatible Issue: #1 --- diagnostic/build-bf2147ac.json | 1 + diagnostic/build-bf2147ac.logd | 10 +++ tools/health_check.py | 109 +++++++++++++++++++++++---------- tools/test_health_check.py | 77 +++++++++++++++++++++++ 4 files changed, 166 insertions(+), 31 deletions(-) create mode 100644 diagnostic/build-bf2147ac.json create mode 100644 diagnostic/build-bf2147ac.logd create mode 100644 tools/test_health_check.py diff --git a/diagnostic/build-bf2147ac.json b/diagnostic/build-bf2147ac.json new file mode 100644 index 000000000..d693a9d81 --- /dev/null +++ b/diagnostic/build-bf2147ac.json @@ -0,0 +1 @@ +{"commit": "bf2147ac", "generated_at": "2026-07-08T12:50:00Z", "validator": "test_health_check.py"} diff --git a/diagnostic/build-bf2147ac.logd b/diagnostic/build-bf2147ac.logd new file mode 100644 index 000000000..49f109122 --- /dev/null +++ b/diagnostic/build-bf2147ac.logd @@ -0,0 +1,10 @@ +Tent of Trials -
