Bug description: $errstr in stream_socket_client() periodically not set when
error occurs
Description:
------------
I've noticed that some errors in stream_socket_client()s connection don't
populate errstr with an error. As far as I can tell, errno is always
populated.
The most consistent case I've found for this if when the error code is 16
- $errstr SHOULD be "Device or resource busy" (according to some googling),
however, it is empty.
I've also come across many errono's that are > 127 and have no errstr.
e.g. 5736689
Reproduce code:
---------------
Unless someone knows how to reproduce "Device or resource busy", then I
can't create any code to reproduce errno 16 having no errstr.
I can reproduce the oddly high errno's (with no errstr) as the example
above appears to be for invalid URLs:
<?php
$stream = stream_socket_client('tcp://tinyu:80', $errno, $errstr);
echo "$errno\n";
echo "'$errstr'\n";
Expected result:
----------------
Not sure what the error number *should* be, possibly 22 (EINVAL), Invalid
argument. I'll go with that:
22
'Invalid argument'
Actual result:
--------------
5736689
