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. Dmitry.

Hi Jakub,


I though not only about FPM, but a technology for any SAPI.

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, executi=
ng 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 prel=
oad it automatically if nothing has been preloaded as part of php_execute_s=
cript / zend_execute_script. However that would mean to do it for each chil=
d (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
