Re: New optimization idea; was: No runtime fetching of built-in global constants

It's great. So it's nothing to do in the scanner. I can just change the CGI code. Thanks. Dmitry. Nuno Lopes wrote:

I'm not Matt, but I'll try to answer :) Actually the new re2c scanner already handles the shebang thing, so I think you can safely remove the explicit support for it in CGI. We had to had that because CLI doesn't explicitly support the shebang line. Nuno P.S.: now it makes sense why we never found the code in the flex scanner that handled the shebang line :P On Sun, Jul 27, 2008 at 11:56, Dmitry Stogov <dmitry@zend.com> wrote:

Hi Matt, At first as you are a scanner expert, I would like you to look into another optimization idea. Probably for historical reason PHP supports shebang lines (#! /usr/bin/php) on top of php files. Especially to handle them PHP (CGI/FastCGI/CLI) opens file and check for it. So even with opcode caches FastCGI PHP does open syscall for the requested script, however with opcode caches it's absolutely useless. In case PHP scanner will handle shebang lines itself, we will able to save this syscall. I never had time and enough flex/re2c knowledge to implement this idea myself. May be you'll able to look into the problem. In case you find a simple solution we will able to do it in php-5.3. Most PHP hosters and large sites use FastCGI with opcode caches (it is also the primary way for MS Windows users), so this optimization is really important.
