#!/usr/bin/env bash
## entrypoint-lsphp.sh — PID 1 for cac-lsphp:phpNN.
##
## The per-site PHP backend for the SHARED OpenLiteSpeed tier. Runs lsphp in
## DETACHED LSAPI mode (`lsphp -b <addr:port>`) and nothing else — no
## webserver. The shared-ols container connects to this over the docker
## network (extProcessor type lsapi, address <this-container>:9000) exactly
## like the shared httpd connects to a cac-fpm container's php-fpm on :9000.
##
## Structurally identical to cac-fpm/cac-litespeed: same `uid`/`user` contract,
## the customer docroot mounted at /home/$user (so PHP sees /home/$user/public_html
## EXACTLY like the standalone tiers — true 1:1 drop-in for WordPress ABSPATH,
## config paths, and DB-stored absolute paths). The only difference is OLS lives
## in a separate container, so this PID 1 is lsphp itself.
##
## THE SYMLINK (see feedback_ols_lsapi_no_script_filename_remap): OLS has no
## ProxyFCGISetEnvIf-style remap — it hands lsphp exactly its vhost docRoot path.
## The shared-ols container serves from its bulk /docker/users->/mnt/users mount,
## so its docRoot (and the SCRIPT_FILENAME it sends us) is
## /mnt/users/<user>/<domain>/public_html. We create a symlink
## /mnt/users/<user>/<domain> -> /home/$user so that path resolves to the real
## /home/$user/public_html files. PHP canonicalises the symlink, so
## __FILE__/__DIR__/realpath all report /home/$user/public_html (verified
## 2026-06-10) — the customer never sees the /mnt/users path.
##
## THE $_SERVER STRINGS: the symlink makes paths RESOLVE, but the raw strings OLS
## put in $_SERVER['DOCUMENT_ROOT']/['SCRIPT_FILENAME'] still read /mnt/users.
## The cac_path_parity extension (baked into the image, configured per-site
## below) rewrites those two at request start, so a site moved from cac-fpm to
## cac-lsphp sees byte-identical values. It replaced an auto_prepend_file
## normaliser that any site's own .user.ini silently displaced — see
## ext/cac-path-parity/cac_path_parity.c.

## sets it in PHP_MINIT_FUNCTION(litespeed) when the PROCESS ENV contains
## LSPHP_ENABLE_USER_INI=on. Without it, lsphp never enters the user-ini chain
## at all — and does so SILENTLY, because `user_ini.filename` / `user_ini.cache_ttl`
## still report their core defaults in phpinfo(). Every other WHP PHP tier
## (cac, cac-fpm, cac-litespeed) honors .user.ini, so leaving it off here made
## the shared-ols tier quietly inconsistent: customer memory_limit /
## max_input_vars overrides were ignored, and — the reason this was found —
## Wordfence's `auto_prepend_file` WAF never loaded on ANY shared-ols site.
##
## Exported here rather than relying solely on the Dockerfile ENV because the
## runuser fallback below resets the environment; an export survives all three
## exec paths. Still overridable per-container (set LSPHP_ENABLE_USER_INI=off in
## the site's env) as an escape hatch for a site whose legacy cPanel-generated
## .user.ini has not been remediated yet.

## ---- per-site ini drop-ins (identical mechanism to entrypoint-litespeed.sh) ----
## error_log → the same customer-visible path cac:phpNN / cac-litespeed use, so
## "where's my PHP error log?" is answered identically across all site types.
## Capture lsphp's own info once and read both answers out of it. Probe with
## `-i` ONLY: lsphp is the LSAPI SAPI, not the CLI — it accepts just
## -[b|c|n|h|i|q|s|v|?] and answers `-m`/`-r` by printing usage and exiting 0, so
## a `lsphp -m | grep` test never matches and never errors either.
##
## ---- CAC-TEST: probe helpers BEGIN ----
## Everything between these two markers is extracted verbatim and executed by
## scripts/tests/lsphp-info-probe.test.sh — the markers are inert comments with
## no runtime effect, and they exist so the test exercises THE SHIPPED CODE
## rather than a copy of it that can drift away from it.
##
## WHY THESE READ `$1` FROM A HERE-STRING AND NOT A PIPELINE. Both probes used
## to be `printf '%s\n' "$LSPHP_INFO" | <reader>`. `lsphp -i` is ~40 KB and both
## readers stop early — `grep -q` on first match, `awk` at `exit` — so the
## reader can close the pipe while printf is still writing to it. printf then
## takes SIGPIPE and dies 141, `set -o pipefail` (line 34) adopts 141 as the
## PIPELINE's status, and the test reads FALSE **because the thing it was
## looking for was present early enough to stop the reader**. Measured on whp02
## against the published cac-lsphp:php83: 5/5 runs status=141 with pipefail,
## 0 without.
##
## It reproduces on some hosts and not others, and the reason is the PIPE
## CAPACITY, not the payload alone. While the writer's whole output fits in the
## pipe it never blocks and always finishes before the reader can act; once it
## does not fit, the early exit is a guaranteed SIGPIPE. Linux gives a pipe
## 64 KiB by default — 40 KB fits, which is why this same image measured 0/10
## on the build host here — but drops NEW pipes to a single page once a user
## passes fs.pipe-user-pages-soft, which is the state a busy production host
## lives in. Forcing the payload over the limit makes it deterministic
## everywhere: 3x this output = 122100 bytes gave 141 141 141 in this very
## image. "It worked when I ran it" was never evidence about this bug.
##
## A here-string is not a pipeline at all: the shell materialises the whole
## string first (temp file, or a pipe only when it provably fits the pipe
## buffer) and the command's status is the reader's own status, so there is no
## second status for pipefail to prefer and no writer left alive to signal.
## `case`/`[[ ]]` would also avoid the pipeline, but would mean re-expressing an
## anchored line match as a glob over embedded newlines; keeping grep/awk with
## the SAME patterns makes this a plumbing change and nothing else.
##
## Both return the reader's status, so a genuinely-absent extension is still a
## clean 1 and a genuinely-missing "Scan this dir" line is still empty output.
