Hi internals,


The preloading RFC is turned into voting state.


https://wiki.php.net/rfc/preload


Many thanks to Anatol, MZPERX and Xinchen for testing.

I hope, most of the implementation issues should be fixed now.


Thanks. Dmitry.

Hi Dmitry,

Apologies if it's been asked before but from:

> Only classes without unresolved parent, interfaces, traits and constant
> values may be preloaded. If a class doesn't satisfy to this condition, ...

Is it possible to inspect which classes have been successfully
preloaded, and/or which classes have failed to be preloaded due to
violation of the appropriate conditions?

cheers
Dan

The RFC states:

| opcache_get_status is extended to provide information about preloaded
| functions, classes and scripts under the “preload_statistics” index.

Right, if I remember properly, this was Rasmus idea.

$ sapi/cli/php -r 'var_dump(opcache_get_status());'

array(9) {
   ...
   ["preload_statistics"]=>
   array(4) {
     ["memory_consumption"]=>
     int(912672)
     ["functions"]=>
     array(?) {
       [0]=>
       string(8) "_preload"
       ...
     }
     ["classes"]=>
     array(?) {
       [0]=>
       string(38) "Zend_Controller_Action_Helper_Abstract"
       ...
     }
     array(?) {
       [0]=>
       string(46) "/home/dmitry/php/etc/preload.php"
       ...
     }
   }
   ...
}

Thanks. Dmitry.

I am cautiously optimistic about this RFC. I hope some of the Future
Scope items can be implemented soon.

Hi,

Besides the yet-another naming convention, I'm quite optimistic about this
RFC.
Now on the convention, is there any reason why single underscore (_) is
used instead of double underscores (__)? We already have __autoload,
__sleep, __toString, __wakeup, etc.

Regards,

Are you talking about _preload()? I guess this is just an example userland
code in the RFC, not a new internal or magic method.

There is no convention at all.  The ini directive opcache.preload allows
to specify a PHP script which will be evaluated.  Period.
