## create-vhost-litespeed.sh — sets up OLS config for one customer site.
##
## Approach: keep the stock LiteSpeed-shipped httpd_config.conf VERBATIM
## (it has all the cgid/lscgid plumbing that lscgid needs to actually
## create its IPC socket), and just APPEND our listeners + vhTemplate.
## The custom vhost template lives at conf/templates/site.conf and points
## at /home/${user}/public_html. envsubst renders our user/domain into
## both files at container start.
##
## Expects in env: user, domain, serveralias (optional).

## Ensure the conf dir has stock config to append to. On first boot with
## a fresh image this is a no-op (image ships with conf/ populated). With
## a future volume mount of conf/, the upstream entrypoint pattern would
## copy from .conf/* — keep parity:
if [ -z "$(ls -A -- "$LSWS_CONF/" 2>/dev/null)" ]; then
  cp -R /usr/local/lsws/.conf/* "$LSWS_CONF/"
fi

## Build the serveralias suffix for vhDomain. Empty for none, else
## ",alias1,alias2" prepended to the comma list.

## --- prep the stock httpd_config.conf before appending ours ---
## Stock ships with `listener HTTP {*:80}`, `listener HTTPS {*:443}`, and
## a `vhTemplate docker` mapped to /var/www/vhosts/$VH_NAME/html — these
## conflict with our ports and would shadow our siteVH vhost. Strip them
## and the demo `virtualHost Example`, but KEEP `listener Default` (it's
## bound to 8088 — harmless internally, removing risks unrelated breakage).
## Always restart from a stock copy so re-runs are idempotent (otherwise
## a second sed pass on already-stripped config corrupts it).
cp /usr/local/lsws/.conf/httpd_config.conf "$LSWS_CONF/httpd_config.conf"

## Strip the stock blocks we replace. Use awk: easier than sed range-deletes
## to skip a NAMED block of arbitrary length terminated by a top-level `}`.
## extProcessor lsphp is stripped because the stock one hard-codes
## PHP_LSAPI_CHILDREN=10 regardless of container size — our appended
## extProcessor scales it from detect-memory-litespeed.sh.
