Hello Dmitry,

please don't apply. The patch looks rather rough and
untested (see
below).

It was tested at least with Zend products and xcache.

Good, I am just worried that we introduce different behavior.
We should just have one execution mode. Your change is better
now having a more detailed view on what it does. But I think
we should not have the old model as well.

Removing early-binding at all might be a subject for PHP6, however in
PHP_5_3 we even keep ze1_compatibility_mode.
I'm not able to remove it.

[skiped]

I'll recheck the -e option. Probably I missied something there.

I did not see -e in the list of allowed flags. So it cannot work.

Then I don't understand you last comments about the patch.

Thanks. Dmitry.

I don't see any sane reason not to remove it :)

Hello Pierre,

it is unused code that does not work as intended and causes trouble. And
at leats it makes maintanance harder. So that is a very big reason to drop
it.

Yes, I fully agree (you may have missed the "not" in my reply :-)

Hello Pierre,

yep, stupid me. I got confused by your wording :-)

WHy not? It's quite broken anyway.

Keeping it seems fairly meaningless (it was a temporary hack anyway).
Since 5.1 (or possibly even late 5.0) releases much of the new
functionality ignores it anyway.

however in
PHP_5_3 we even keep ze1_compatibility_mode.

I do not want to remove early binding. In fact I always wanted to have
early binding as much as possible. Because that is faster and makes
compiler caches easier. So why slow down stuff? A Compiler cache wants
everythign as static as possible which means a compiler cache wants early
binding. This is also faster. So what are you proposing here?

Best regards,
Marcus
