php-opcache: add port

[macports.org@…]

PHP 5.5 introduces a new feature, OPcache:

• ​http://php.net/opcache

To use it with PHP 5.5, it must be built with --enable-opcache:

• ​http://php.net/manual/en/opcache.installation.php

However, the current php55 port does have this configured:

$ php -v
PHP 5.5.0 (cli) (built: Jun 22 2013 00:21:42)

$ php -i | grep "^Configure Command" | fold -s
Configure Command =>  './configure'  '--prefix=/opt/local'

'--with-config-file-scan-dir=/opt/local/var/db/php55' '--disable-all' 
'--enable-bcmath' '--enable-ctype' '--enable-dom' '--enable-fileinfo' 
'--enable-filter' '--enable-hash' '--enable-json' '--enable-libxml' 
'--enable-pdo' '--enable-phar' '--enable-session' '--enable-simplexml' 
'--enable-tokenizer' '--enable-xml' '--enable-xmlreader' '--enable-xmlwriter' 
'--with-bz2=/opt/local' '--with-mhash=/opt/local' 
'--with-pcre-regex=/opt/local' '--with-libxml-dir=/opt/local' 
'--with-zlib=/opt/local' '--without-pear' '--disable-cgi' '--disable-fpm' 
'--enable-cli' '--with-libedit=/opt/local'

The source confirms this:

• browser:trunk/dports/lang/php/Portfile#L147​

Please build the php55 port with the --enable-opcache flag.

Thanks for your consideration.

Thanks for the ticket. In the future, please Cc relevant port maintainers.

The page you linked to says this is an extension. So we need a new php-opcache port for it.

[macports.org@…]

I'll defer to your expertise in how this functionality should be delivered, but it seems that while it can be compiled as a PECL extension for PHP 5.4 & 5.3, the documentation says that PHP 5.5 must be built with it:

From ​http://php.net/manual/en/opcache.installation.php:

PHP 5.5.0 and later

To use OPcache with PHP 5.5.0 or later, you must compile PHP with the --enable-opcache option, then use the zend_extension configuration directive to load the library at runtime.

Perhaps a possible solution is to compile the php55 port with --enable-opcache, but separate the library file and configuration directive to a php55-opcache port?

To use OPcache with PHP 5.5.0 or later, you must compile PHP with the --enable-opcache option, then use the zend_extension configuration directive to load the library at runtime.

The documentation has the same wording for all the extensions. Take curl for instance:

​http://php.net/manual/en/curl.installation.php

To use PHP's cURL support you must also compile PHP --with-curl[=DIR]

We want PHP modules as a separate ports, so that having already installed php, you can later decide to easily add and remove extensions. This is accomplished by running configure and make and make install a separate time, with only the configure options to enable the given extension.

Ah, thank you for clarifying -- seems like an elegant solution to the end user to give them the flexibility they might need. -Cheers

Added php-opcache for php53 and php54 in r107248. Still thinking about how I want to handle the php55 version (as part of the php-opcache port, or as a subport of the php port).

[ryandesign (Ryan Carsten Schmidt)]

Added php55-opcache subport to php port in r107250.
