Hi,
The proposed patch removes code that implemented shebang line support
(#! /usr/bin/php). Starting with PHP-5.3 it is handled by scanner, and
we don't need to check it twice.
With this check removed, it's become possible to eliminate the open()
syscall (and also several fstat() and mmap() calls) for the requested
file with opcode caches. The patch does it by replacing VCWD_FOPEN() in
php_fopen_primary_script() by zend_open_stream() which call for callback
that can be overridden by opcode cache.
I like to commit it into HEAD and PHP_5_3 on weekend.
I hope nobody have objections.
Thanks. Dmitry.
