set_error_handler(null) and set_exception_handler(null) now return the
previous error/exception handler instead of just returning bool(true).
This is consistent with the behavior of these functions with non-null
values.
This allows the error handler to be reset using set_error_handler(null).
As the code suggests this behavior was already previously intended, but
the callback check was done too strictly.
This reverts the following two commits:
* 6ba2e662e4
* d8f8e98d8e
Laruence already did some partial changes to set_error_handler and
set_exception_handler. I'm reverting those modifications to apply the full
set of changes. (The modifications changed the code structure in a way that
would lead to more duplication with the new behavior.)
EG(arg_types_stack) is now also backed up when generators are used. This
allows the use of yield in nested method calls.
This commit adds two new functions to the zend_ptr_stack API:
zend_ptr_stack_push_from_memory
zend_ptr_stack_pop_into_memory
both taking the following arguments:
zend_ptr_stack *stack, int count, void **pointers
As per libcurl documentation :
When libcurl returns -1 in max_fd, it is because libcurl currently
does something that isn't possible for your application to monitor
with a socket and unfortunately you can then not know exactly when
the current action is completed using select().
The API is supported since Windows Vista and requires targeting Vista
when compiling PHP. Pierre had asked to disable this by default, even
when targeting Vista/Windows Server 2008.
Since XP will not be supported anymore on php-next, any rationale
for this option will not apply anymore.
The multicast support in PHP 5.4 makes use of MCAST_JOIN_GROUP if it is present.
The problem is that OSX 10.7 added the constant, but did not correctly implement
the feature. This causes the setsockopt call to fail.
The solution to the problem is to not use MCAST_JOIN_GROUP on OSX.
For reference, this was also done in VLC:
