* Out-of-range numbers overflow/preserve least significant bits (no LONG_MAX/MIN limit)
* See bug #42868 (presumably-rare platform with different results in 5.2)
* On 32-bit platforms with 64-bit long type, a zend_long64 cast has been added,
otherwise it's the same as 5.2
* Use this conversion method everywhere instead of some plain (long) casts
Added 'L' parameter parsing specifier to ensure a LONG_MAX/MIN limit:
* Essentially what 5.3's new conversion was doing in most cases
* Functions with "limit" or "length" type params could be updated to use this,
and prevent confusing overflow behavior with huge numbers (*also* in 5.2)
- See bug #47854, for example; or even #42868 again

or overloaded functions and methods. The issue is that a function might
set and rely on a certain mode and then calls another internal function
which changes it again, probably changing it back to the normal mode.
With this change we need to drop all calls that change the mode back to
normal using php_std_error_handling(). However there might be places
where someone wants to restore the last mode. If there is such a case we
need to add two functions one to save and one to restore. I briefly on
this and not all cases are clear, especially one in sqlite but that seems
to be a rather misleading comment. Eitherway I chose to not drop and mark
as deprecated for now.
Here are the signal changes from the 5.3 branch that optimizes signal
handler registration and switches from longjmp to siglongjmp in order
to make signal mask handling consistent across different UNIX operating
systems.
The following pseudo-code explains how it should be used in opcode cache.
function cache_compile_file($filename) {
if (!is_cached($filename)) {
...
orig_compiler_options = CG(compiler_optins);
CG(compiler_options) |= ZEND_COMPILE_IGNORE_INTERNAL_CLASSES |
ZEND_COMPILE_DELAYED_BINDING;
$op_array = orig_compile_file($filename);
CG(compiler_options) = orig_copiler_options;
...
} else {
$op_array = restore_from_cache($filename);
}
zend_do_delayed_early_binding($op_array);
}
