# memory_regression_gate.sh - Automated pass/fail gate over client memory.
|
|
#
|
|
# Wraps scripts/memory_probe.sh with thresholds so memory regressions fail
|
|
# loudly (nightly job, pre-release check) instead of being rediscovered when
|
|
# the machine starts swapping.
|
|
#
|
|
# Baseline (2026-07-04, selfdev build, 8 MB / 322-message hog session), after
|
|
# the retention + live-heap work (mmap-threshold pin, idle trim, syntect
|
|
# regex-onig backend, inline-image payload release):
|
|
#
|
|
# idle rss_anon: ~38 MB (was ~69 MB)
|
|
# idle live heap (allocated): ~30 MB (was ~60 MB)
|
|
#
|
|
# Thresholds sit roughly halfway between the fixed and regressed values, so
|
|
# normal variance passes but a real regression toward old behavior fails.
|
|
#
|
|
# Usage:
|
|
# scripts/memory_regression_gate.sh [--session <id>] [--idle-secs <n>]
|
|
#
|
|
# Env overrides:
|
|
# JCODE_MEMGATE_SESSION probe session id
|
|
# JCODE_MEMGATE_MAX_RSS_ANON_KB idle rss_anon bound (default 56320 = 55 MiB)
|
|
# JCODE_MEMGATE_MAX_LIVE_HEAP_BYTES idle allocated_bytes bound (default 47185920 = 45 MiB)
|
|
#
|
|
# Exit codes: 0 pass, 1 threshold exceeded, 2 could not measure, 3 skipped
|
|
# (probe session missing on this machine).
|
|
#
|
|
# Emits one machine-parseable line: `JCODE_MEMGATE_RESULT {json}`.
