jknapp	cfdaae116a	tune(litespeed): bump opcache 32→64 MB / 4000→8000 files + add per-site override ... 32M/4000 was too aggressive for heavy WP+Divi+WC sites: 3000+4000 unique PHP files each blow through max_accelerated_files, causing constant eviction + recompilation thrash. Manifested 2026-06-03 as ~40% sustained CPU on alphaoneaminos and 5378 oom_kills/9h on brain-jar. 64M/8000 fits Divi + WC + WP core bytecode without eviction. N lsphp × 64 MB ≈ 512 MiB shmem worst case — still under the per-instance setUIDMode fan-out from the original 128M problem (which was 1+ GiB). Per-site override (OPCACHE_MEMORY_MB / OPCACHE_MAX_FILES env vars) lets the panel push down for low-traffic sites or up for outliers without rebuilding the image. WHP panel UI ships in a follow-up commit. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-06-03 06:21:37 -07:00
jknapp	87f154cdc8	refactor(litespeed): drop setUIDMode for shared lsphp + cut opcache 128→32M ... OLS runs as the customer user end-to-end (server-level user/group set by create-vhost-litespeed.sh), so lsphp inherits that uid without per-request suEXEC. Eliminates the per-httpd-worker lsphp instance fan-out — one shared lsphp parent now serves all httpd workers via the shared socket. Combined with opcache.memory_consumption 128→32M, brain-jar measured shmem dropped from ~880 MiB → 32 MiB and memory.current from ~1.1 GiB → 67 MiB at the 1.5 GiB cap. No new oom_kills since the change. Safe because cac-litespeed is one-customer-per-container — the container boundary is the privsep boundary.

jknapp	55c28a0c11	Add cac-litespeed image family (OpenLiteSpeed, native LSAPI) ... New paid-tier per-customer image built on litespeedtech/openlitespeed:1.8.4-lsphpNN. Matrix: 8.1-8.5. Native LSAPI suexec to customer uid, server-level LSCache, all WP/WooCommerce extensions (memcached, redis, imagick, mbstring, etc.) baked in. Files: - Dockerfile.litespeed (FROM prebuilt LiteSpeed base, layers wp-cli/composer/mariadb) - configs/litespeed/{httpd_config,site-template,lsphp-overrides}.tpl - scripts/{entrypoint,create-vhost,detect-memory}-litespeed.sh + install-lscache-wp.sh CI: new Build-LiteSpeed-Images matrix job. OLS_VERSION pinned to 1.8.4 (only release with prebuilt images for all 5 PHP versions on Docker Hub).
