Add port range verification of listening port with -S option for the php cli.
This fixes inconsistent listening port due to unverified cast from long to short
with htons(3).
Using getaddrinfo is perhaps not a good idea... if we are not able
to listen on multiple addresses...
At least this message should help to diagnose problem, ex
... Found address for localhost, socket opened on ::1
... Found multiple addresses for localhost, 127.0.0.1 ignored
Unlike other settings, this has a perfectly reasonable default, calculated using
a dynamic formula. If the default was hardcoded to "2" or something, then it
would make sense to have a warning, since that could potentially be bad, but for
a dynamically calculated value based on other mandatory settings, a notice ought
to be enough.
The log level will be ignored throughout log events in fpm_unix_init_main, until
the very end when zlog_set_level is finally called.
In particular, fpm_unix_conf_wp may throw notices like this:
> [08-Nov-2014 17:13:36] NOTICE: [pool www] 'user' directive is ignored when…
Which will still appear even if log_level in php-fpm.conf is set to warning+
Restore default behavior when no address configured:
Listen on all IPv4 addresses.
At some time we could consider to switch to all IPv6
but this will be a BC break.
The hash need to be unique per IP + Port
Previous version have (IPv4 only)
sprintf(key, "%u.%u.%u.%u:%u", IPQUAD(&sa_in->sin_addr), (unsigned int) ntohs(sa_in->sin_port));
ProxyPass is unable to provide correct PATH_INFO
as it is not aware of file path (while SetHandler is).
As we can extract PATH_INFO from PATH_TRANSLATED,
we also need to check if present in SCRIPT_NAME
and remove it.
