Bug description:Wrong data inserted with mysqli/mysqlnd when using
bind_param,value>LONG_MAX
Description:
------------
LONG_MAX is differs from platform to platform.
Because zval internally uses a signed long for integer fields when the
value in the script is over LONG_MAX, or under -LONG_MAX-1 then the value
is fit into a double. When using mysqli_stmt_bind_param with such a value
and "i" modifier then the value is converted back to long, which results in
incorrect results - like if the VALUE was LONG_MAX+1 the result will be -1
(internally it is a signed long).
Test script:
---------------
CREATE TABLE tint(a bigint unsigned);
./php -r
'$c=mysqli_connect("127.0.0.1","root","root","test");$s=$c->prepare("insert
into tint
values(?)");$param=4294967295;$s->bind_param("i",$param);var_dump($s->execute());'
bool(true)
Expected result:
----------------
Don't bork the data. Check if the value can't be fit into a long, and if
this is the case use string to send to the server (changing the modifier to
"s" just for the next execution, preserve "i" for further executions).
Actual result:
--------------
-1
