Re: FPM preloading of PHP files

Hi Jakub, I thought about pre-loading explicitly specified files (or directories) on PHP startup, before forking worker processes. As result all pre-loadd files should be available to all workers. Of course the should be kept in immutable form. Thanks.

Pre-loaded classes and functions might be kept in CG() tables, in the same way as "internal" ones. EG() constants and variables may be re-created at start of request, executing pre-loaded PHP code. Few years ago, I developed something similar for PHP-5. Yeah that's what I kind of meant by the engine support. :) My idea was more about when it should be preloaded. For example one option would be to preload it automatically if nothing has been preloaded as part of php_execute_script / zend_execute_script. However that would mean to do it for each child (basically use it for all request for the child process life). It should work and might be a viable options for the initial implementation but more optimal would be do it once for all children running in the same pool which could be doable using the pool managers. I think it would be great to have some kind of API so the SAPI can explicitly preload the script. Cheers Jakub
