Generators Revisited View as Markdown

Hi Dmitry,

s/ informatin/information
in the UPGRADING file.

Best regards.

Hi

I've tried to review the generators related changes made in PHP-5.5 and
improve them from both consistency and performance points of view.
The patch also makes a small performance improvement to PHP-5.5 in general,
however, it changes some ZE internals that can be used by
some extension (e.g. XDebug).

You can find the list of changes in the UPGRADING file.

http://pastebin.com/AT0SQhAH

Please, review the patch and test it with your custom extensions.

I would like to commit it on Friday morning. Objections?

I also have some additional proposals:

1. EX(Ts) access optimization. With this patch it must be possible to
   access temporary variables using "execute_data" as the base pointer.
   "execute_data.Ts" might be removed at all. In general the same optimization
   might be done for EX(CVs) as well.

2. May be it makes sense to forbid return/yield usage in "finally" blocks
   using compile time error. Their behaviour is really unclear.

Any thoughts?

Thanks. Dmitry.
