Restored double->long conversion behavior to that of PHP 5.2 (on most platforms) and prior:
* 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
# Test updates coming
After the sigsetjmp change, this is patch #2 in an effort to get some
sanity restored to signal handling in PHP.
This patch does two things. First, it makes it possible to reset the
timeout without resetting the signal handlers. This is important for
cases where an extension may have deferred signals in its MINIT in order
to implement critical sections. It also lays the groundwork for cleaning
up our signal handling and perhaps eventually implementing our own
signal deferring mechanism so we can have true critical sections.
The second thing this does is to make it possible to terminate the current
child process (only for Apache1 at the moment) on a timeout. There are
a number of extensions that are unhappy about being longjmp'ed out of
and when this happens on a timeout they are left in an inconsistent state.
By turning on exit_on_timeout you can now force the process to terminate
on a timeout which will clean up any hanging locks and/or memory left
hanging after the longjmp.
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);
}
