Hello all,
I wanted to suggest back porting the behaviour of the DVAL_TO_LVAL macro
from zend_operators.h from 5.3 to 5.2, and wondered whether people
thought this was a good idea or not?
The reason I want to do this is that while writing some tests, I noticed
that the behaviour of casting a float to an int is a bit
counter-intuitive on 64bit platforms for PHP 5.2. It looks as though
this has been fixed in 5.3, and it would seem like a good idea to put
this change back to 5.2 as well. From a personal point of view, it would
mean I could write one test that would work on both 5.2 and 5.3, but it
also seems like a sensible change, as the current behaviour is
non-obvious. The change would cause some current tests to break, but I
am happy to do the work to fix those up.
This is how a few expressions get evaluated at the moment. Changing the
macro would make the 5.2 behaviour match 5.3
Expression 5.3 (RHEL5-64) 5.2 (RHEL5-64)
(int) (PHP_INT_MAX) 9223372036854775807 9223372036854775807
(int) (PHP_INT_MAX + 1) 9223372036854775807 -9223372036854775808
(int) (PHP_INT_MAX + 1000) 9223372036854775807 -9223372036854775808
(int) (PHP_INT_MAX + 10000) 9223372036854775807 -9223372036854765568
Does this seem like a good change?
