Link: http://git.php.net/?p=php-src.git;a=commitdiff;h=6b4148bc9705d2668dd8589009215a8eb3076f31 Log: Fixed Bug #64565 copy doesn't report failure on partial copy _php_stream_copy_to_stream_ex, when mmap is possible, doesn't check if actually written bytes match read bytes. Fix this (paranoid check) to be consistent with non mmap mode Seems hard to add a unit test, as this rely on a full filesystem.
