Summary0000229: Cannot change a string to one which has spaces in it.
Description

I attempt to change a variable containing a string (the string is arbitrary) using the property_set request to a string which contains spaces, but it fails. I can change the string to anything else so long as it has no spaces in it.

eg I have a string with the contents "Welcome to PHP", and I tried to change it to "This is", but it is rejected. The command issued is

property_set -i 189 -n $b -d 0 -l 12 -- VGhpcyBpcw==

<?xml version="1.0" encoding="iso-8859-1"?>
<response command="property_set" transaction_id="189" success="0"></response>

If I change it to "ThisIsI" then the command is
property_set -i 193 -n $b -d 0 -l 12 -- VGhpc0lzSQ==

<?xml version="1.0" encoding="iso-8859-1"?>
<response command="property_set" transaction_id="193" success="1"></response>

I have checked that the base64 encoding decodes correctly to a string with spaces.

Additional Information

I have also tested this with 2.0.0rc2-dev built on 11th Dec 06 and the problem exists there as well.

Although property_set still needs some work, this is expected behavior. Send the variable with quotes around it and it will work just fine. Basically, Xdebug does internally:

$cmd = sprintf("%s = %s", $name, $data);
eval($cmd);

where $name is the -n option and $data the -- option. As you can see that without the "'s, the eval command is not valid. I will keep this report open though as a reminder to properly implement property_set.

Thanks Derick, I have changed my client as you suggest and it works fine.

That has been fixed in CVS now. If you use the -t argument Xdebug will not use eval, but install just set the variable. You don't need to escape strings with " then any more. Only in case where the -t argument is missing Xdebug will use eval() internally to set the property.
