Hi Sara,
I fixed one error in your patch, so now it passes all tests.
BTW I am against this patch.
1) It adds sloppily built functionality into the core and slowdowns EACH
dimension or property fetch both at run-time and compilation-time. I think
it is a big cost for $_GET/$_POST encoding-conversion, but it is only my
opinion.
2) It adds pointer to zend_auto_global into zend_compiled_variable. This
makes troubles for opcode caches - zend_compiled_variable(s) may lay in
shared memory, so they cannot point to process specific data. I think this
issue can be fixed using indirect pointer (index).
I would prefer rollback "auto-globals CV" patch and commit (or not) the
whole patch after conclusion.
Why did you reject auto-globals as overloaded arrays?
Thanks. Dmitry.
