Bug description:mysqli_poll() is broken on win x64
Description:
------------
mysqli_poll() in user space invokes _mysqlnd_poll(). In that function
php_select()
is used for polling. The windows implementation works with int for
descriptors,
however php_socket_t data type is used in mysqli. This has two flaws
- generally on windows, php_socket_t is a typedef from SOCKET and is
unsigned,
that means any usual UNIX socket checks want work, say checking if
descriptor is
negative
- on 64 bit windows this is a breach, because SOCKET there is unsigned 64
bit
integer while php_select() implementation still uses 32 bit integers.
php_select()
internally calls select(), which on windows expects an 32 bit integer as
descriptor as well.
As result mysqli_poll* function family is broken on 64 bit Windows.
