Debugger: Evaluate Variables

[Jürgen]

I have still problems with the debugger.
So I tried to test this with the xdebuger client:

I testet it with this command:
property_get -n "$a" -i 9
and get a valid answer "1" in the response string
( please send me a email for sending a hardcopy of the console output)

I hope this helps You to get the debugging working.
Feel free to contact me for further informations and tests.

with kind regards
Jürgen

For the moment i can't help on xDebug.
This could come from some compiling options of PHP...
Could you please send some code snippets (and expected results) ?

Thank you for your report,
Pierre.

Hi Pierre,
below is the testet php-code and the corresponding debugger-log.

what I have done:
I activate the debugger; (activate gets "gray")
set a breakpoint to Line "echo $testvar";
add "test2" with "eval selected" to the evaluation-window;
hit "run" ( the debugger stopps at the breakpoint)
... but no Variable was shown in the evuluation-window. The same I have tested with "step-into" (every step is listed in the debugger-log - but not evuluation of the variable)

<?php
$testvar = "aggggbc";
$test2= 'xxx';
$a= 1;
echo $testvar;
phpinfo();
?>

Debugger Log:
<init fileuri="file:///C%3A%5Cxampplite%5Chtdocs%5Cphpinfo.php" language="PHP" protocol_version="1.0" appid="2068" idekey="devphp1"><engine version="2.0.0beta3-dev"><![CDATA[Xdebug]]></engine><author><![CDATA[Derick Rethans]]></author><url><![CDATA[http://xdebug.org]]></url><copyright><![CDATA[Copyright (c) 2002-2005 by Derick Rethans]]></copyright></init>

xdebug.remote_mode=req
xdebug.remote_handler=dbgp
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.idekey=devphp
...

testet with Version 2.0.13.249 11-feb-2006

the debugger-log lookes like the watch-variable was never send to the debugger (command: property_get -n "$a" -i 9 )
like shown in the obove posting this command works if it was "manual" send with the xdebug test-client.

( I hope all tags ind the debug-log are shown )

with kind regards

some additional remarks:
even "context_get" works (but I do not understand the "CDATA" from the string-Variables):

debugger-log:
<response command="context_get" transaction_id="93"><property name="a" fullname="$a" address="10245072" type="int"><![CDATA[1]]></property><property name="testvar" fullname="$testvar" address="10244720" type="string" encoding="base64"><![CDATA[YWdnZ2diYw==]]></property><property name="test2" fullname="$test2" address="10244552" type="string" encoding="base64"><![CDATA[eHh4]]></property></response>

only in the "evalation"-Window no value was displayed.

Hi Jürgen,

xDebug speaks xml - why not ;)
CDATA is a special keyword which comes with xml.
Our debugger-log said
$a=1
Then xDebug added a base64, not really easy to translate (http://makcoder.sourceforge.net/demo/base64.php)
$testvar='aggggbc' (translation of YWdnZ2diYw== )
$test2='xxxx'      (translation of eHh4 )

Since there were no 'arrays, objects', that was simple enough. Thus, imho, 'context_get' will have to implement a sort of object inspector in a future version ;)

Best regards,
Pierre.

really perfect feedback from pierre. :-)
if you need more informations about the protokoll from xdebug please read:
http://www.xdebug.org/docs-dbgp.php

Best regards,

[Jürgen]

thank you very much for the explanation of the xdebug protokoll ,-) even after sending the message I find myself that the data is "base64" coded.

... but to come again to  core of my posting:
I want to report the following bug:

Even when the xdebug communication works:
The values of the variables are not shown in the evualation Window !!

( all the xdebug-logs are only include to show what happens in the background on the xdebug-communication)

with kind regards
Jürgen

Because I got no real answer to my core-question I want to ask again:

Is this (not showing evulation of variables) a known bug in the experimental version 2.0.13.243 (because the debugging ins not full implemented until now)  ?

or

is this behavior not reproducible and the evulation of variables in the debugger should work in this version ?

thanks for your work and
kind regards
Jürgen

Hi Jürgen

the evaluation of variables is not working in the current versions of dev-php. debugging is not full implemented at this time and i have not the time to complete it, but i hope to work on it soon.
thanks for the feedback.

even if the answer is not so good for me, I thank you very much for your quick reply and your current work on dev-php.

with kind regards
Jürgen
