Fedora 27, httpd in thread mode by default, need for ZTS php modules

[Remi Collet]

Hi,

Starting with Fedora 27, the Apache Webserver is now configured by
default to use event MPM (threaded)

Which means ZTS mod_php will be used.

Some packaged extensions only provide the NTS build, so won't be
available in web context (using httpd + mod_php), but only when

- php-fpm is used
- httpd is configured to used prefork MPM (not threaded)

So, probably worth investigating if the ZTS module can be enabled during
the build.

Example, for ssh2 extension:
http://pkgs.fedoraproject.org/cgit/rpms/php-pecl-ssh2.git/diff/php-pecl-ssh2...

Notice, mod_php in ZTS mode is not recommended per upstream documentation:
http://php.net/manual/en/install.unix.apache2.php
http://php.net/manual/en/faq.installation.php#faq.installation.apache2

So php-fpm should be preferred.

So web applications should not require "php" (or mod_php) but php(httpd)
instead (provided by both php and php-fpm packages).

Additional information:

php-fpm is now the default configured way to enable PHP with apache in F27+

I.e. mod_php for ZTS is still provided but not loaded by default, as
unsupported by upstream.

Remi was there an F27 change filed for this... I don't see one?

It's quite a significant alteration in behaviour and the vast majority of
php users in Fedora who use httpd use mod_php and will be broken by this.

It really needs to be clearly marked in the release notes, coordinated with
php applications shipped in Fedora and be marked with instructions on how
to switch between the two methods... plus the discussion of how to handle
the upgrade scenario needs to be had.

dnf install <yourPreferredApp>
systemctl start <yourPreferredWebServer>

Still work out of the bow, like previously

Changes are now on the road to F27 testing
