0000948: Unused+DeadCode not returning (-2) because of nested IF

Sat, 18 May 2013 23:30:00 +0100

Having an inner IF inside an outer IF results in two lines being returned as (-1) rather than (-2) in the xdebug_get_code_coverage() return array.

In my fooGood() method coverage, the regular behavior return of (-2) for the "} else {" line and the function end line "}", as expected.

In my fooBad() method coverage, the equivalent lines (ELSE and function close brace) get return values of (-1) instead. The expectation is that (-2) would be returned for both lines.

0000942: Strack traces can be unreadable due to missing foreground colour

Sat, 18 May 2013 22:33:05 +0100

Strack traces set background colours but not foreground colours. That often makes the text barely unreadable, depending on what colours are set in the site's CSS.

0000943: It can't debug in eclipse neither on windows or linux(ubuntu)

Sat, 18 May 2013 22:30:41 +0100

I used eclipse to debug on Windows, It's always right before, but It couldn't be launched sometimes ago. I didn't know why it, I tried to debug on Linux in same way, the results was same as. Maybe it's a bug or not.

here is some informations I used strace get it,

0000946: Web page describing remote debugging has a link which confusingly links to the same page

Sat, 18 May 2013 22:24:19 +0100

In the section describing the remote_handler setting at http://xdebug.org/docs/remote#remote_handler [^] there's a sentence which reads, "See more information in the introduction for Remote Debugging."

Clicking on this link causes the browser to reload the same page (as though it were a new / different page). Usability studies show that this behaviour can cause confusion for users.

I'd suggest either removing the anchor altogether or else modifying the href attribute so that it refers to a specific named anchor on the same page.
If keeping the sentence, I'd suggest including the word "above" so that it's clear that the introductory information it refers to is on the same page.

0000945: configure uses wrong path to php

Sat, 18 May 2013 22:23:54 +0100

When installing Xdebug on a machine with php pre-installed (like Mac OS X) you'll want to keep your own version of php separate from the Apple supplied one. On *nix system, the default way is to have your own version of php in the /usr/local/bin directory. The Xdebug install process ignore this practice and uses the version in /usr/bin instead. Subsequently, hooking Xdebug to the wrong php version/process.

I have MAMP installed and the steps to reproduce, assumes you have an installation of MAMP. This bug should be reproducible on any *nix machine, though.

0000940: xdebug quits when it reaches an object cast to array that contained protected properties

Sat, 18 May 2013 22:09:19 +0100

xdebug quits session when it reaches an object, that contains protected properties, that has been cast to an array.

0000610: Xdebug sends invalid '�' char reference in response

Sat, 18 May 2013 22:03:28 +0100

Try to debug the file:

class SimpleClass {
private $_a;

public function __construct($a) {
$this->_a = $a;
}
}

$a = new SimpleClass(2);
$a = (array) $a; // <-- put breakpoint here
echo("unreachable");

Put breakpoint at line before last one. When execution breaks here, try to get the context. Response will contain "?" parts that are not allowed in XML according to the spec: http://www.w3.org/TR/REC-xml/#wf-Legalchar [^]

0000924: $test = array("\0" => ''); renders variable view inoperable

Sat, 18 May 2013 19:37:53 +0100

Encountered w/ eclipse, 4.2.1 and earlier 3.x.

Seems like a simple variable array declared as

$test = array("\0" => '');

Will wipe out the variable view such that no variables will appear in the window during subsequent code execution.

0000926: Xdebug is Not Running

Sat, 18 May 2013 19:36:34 +0100

I have followed the instructions provided below:

Xdebug installed: no

Instructions

Download xdebug-2.2.1.tgz
Unpack the downloaded file with tar -xvzf xdebug-2.2.1.tgz
Run: cd xdebug-2.2.1
Run: phpize (See the FAQ if you don't have phpize.

As part of its output it should show:

Zend Module Api No: 20090626
Zend Extension Api No: 220090626
If it does not, you are using the wrong phpize. Please follow this FAQ entry and skip the next step.

Run: ./configure
Run: make
Run: cp modules/xdebug.so /opt/php-5.3.18/lib/php/extensions/no-debug-non-zts-20090626
Edit /var/www/conf/web1/php.ini and add the line
zend_extension = /opt/php-5.3.18/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so
Restart the webserver

This is the section of my php.ini with xdebug information:
zend_extension=/opt/php-5.3.18/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so
xdebug.remote_host=www.aaabs.org
xdebug.remote_enable=1
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.remote_mode=req

I copy and paste the extension directory: "/opt/php-5.3.18/lib/php/extensions/no-debug-non-zts-20090626" do an "ls" and see xdebug.so, so I know the path is correct.

I created a phpinfo.php file at the root location of www.aaabs.org with these contents:

echo phpinfo();

Paste the source of the document into the field at: http://xdebug.org/wizard.php, [^] and the results are always as you see in the summary information that I posted at the top.

I look at my session variable in Google Chrome at I have XDEBUG_SESSION = PHPSTORM.

Everything looks right, but Xdebug is not loading.

0000899: Hang after conditional breakpoint evaluation causes an exception

Wed, 15 May 2013 12:43:36 +0100

If evaluation of a condition on a breakpoint in a for loop (seems to be important, can't repro it without) causes an exception to be thrown (in this case from a magic __get method) the script hangs while leaving either the for loop or the try/catch clause and the php process consumes 100% cpu.

I ran into this while trying to come up with a small reproducible case of the same exception escaping xdebug and actually being caught by the script's exception handler. Unfortunately I haven't been able to come up with that case but attached a screenshot of it occurring.

And why when debugging this script wouldn't Xdebug be logging to xdebug.remote_log?

0000918: XDebug connect to IDE but browser says Empty response

Tue, 14 May 2013 19:16:44 +0100

I'm using IntelliJ with PHP Plugin (which should be the same as PHPStorm).

xDebug does send connection and IDE break on breakpoint.
But as soon as it does this, the browser instead of waiting for the script end, it sends an error 324 (chrome)

I'm using .htaccess config mode with :
php_value xdebug.remote_connect_back 0
php_value xdebug.remote_enable 1
php_value xdebug.remote_host 10.13.11.111

Php version on server is :
#php --version

0000941: trace_format=1 is being ignored

Tue, 14 May 2013 19:16:18 +0100

When changing the variable trace_format to 1 or 2, Xdebug is not generating the expected file output.
The change can be done in the php.ini or directly from the command line (using php -d xdebug.trace_format=1)

Definitely I'm doing something wrong here, but I'm not being able to identify what is the problem.

0000947: Newlines converted when html_errors = 0

Doing "Run File" works fine.

0000765: Xdebug slows down PHP execution 30%-50% when running inside VirtualBox

Sat, 27 Apr 2013 02:24:38 +0100

Hi,

I run php-fpm 5.3.9 with xdebug git (2.2dev) in virtualbox and it cause PHP to run 50% slower (a test page results from 170ms (xdebug disabled) to 250ms (xdebug enabled), tested several times.). I realize that using xdebug will require more run time for PHP, but I have used it before in windows and it doesn't make that much of slowdown.

Here are the settings I used
[xdebug]
zend_extension=/opt/php/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so
xdebug.overload_var_dump=0

Other details:
Arch linux 32 bit
PHP 5.3.9 with fpm SAPI, APC enabled
Virtualbox 4.1.6 running inside Windows XP 32 bit
Core 2 duo E8400 (No VT-x)

0000812: excessive overhead while not enabled.

Sat, 13 Apr 2013 21:03:35 +0100

(I'm actually using 2.2.0RC1, compiled from source, but that's not in the menu in the bug reporting system)

I'm seeing per-function call overhead in php processes, including a gettimeofday process, even when no tracing or profiling is enabled. This comes with a significant performance overhead such that I cannot leave the module loaded while not actively in use.

I'd like to be able to leave the module loaded routinely, for cookie triggered use only, but currently the overhead is just too high (about 250ms extra latency per page).

0000658: Eclipse/Xdebug crashes when debugging drupal

Sat, 13 Apr 2013 16:35:22 +0100

Eclipse/Xdebug crashes randomly - but very, very often - when debugging drupal in Eclipse. I have been debugging my other php scripts without problems for more than a year, but when trying to debug drupal cause crash. Eclipse throws a small window saying "Apache HTTP server has encountered a problem and needs to close etc.". Then looking at the data of the error report it says (among other things): "ModName: php_xdebug-2.1.0-5.3-vc6.dll", "ModVer: 2.1.0.5" and "Offset: 0000bf44". I can provide a screenshot from the crash if that helps. I'm using the Xampp 1.7.4 Beta2, but the same happen other versions of Xampp as well.

0000579: The ability to start and stop xdebug remote sessions from php code.

Fri, 29 Mar 2013 21:26:07 +0000

currently it is possible to start an xdebug remote session by adding XDEBUG_SESSION_START to the URL or by a setting in php.ini to always start the remote sessions.

It would be nice to have a feature that triggers the remote session to start from within the code.

WHY: When trying to debug the returning IPN information from Paypal the IPN is sent behind the scenes, not in the browser. If it was possible to activate a remote debugging session from the code then I could add that to the code that receives the paypal IPN and start debugging from there.

Currently it is necessary to turn the debugging session on for everything happening around as well.

It would be nice to be able to not debug everything else and just start stuff when the IPN comes back.

Thanks.

0000938: Unreliable debugging of forking processes

Mon, 25 Mar 2013 12:30:53 +0000

If you decide to remote debug code that use pnctl_fork() function at least both eclipse and xdc 1.0b5 either crash or don't stop at desired breaking points.

0000785: The Xdebug Profiler does not handle closures and call_user_func_array well

Sat, 23 Mar 2013 14:50:08 +0000

I'm not sure if the problem is with kcachegrind or with Xdebug, but if you have code that calls closures, it breaks the call graph. You can see the call graph before and after the closure call, but not the whole graph linked to together. Is it possible to assign each closure a unique name so kcachegrind knows to make the correct links?

0000732: 'property_get' command should accept integer array key surround with quotes

'property_get -i 11 -n $b['1'] -d 0 -c 0 -p 0' will return 'can not get property'

There is currently no feedback if Xdebug can't open or write to the remote debugging log.

0000863: xdebug.overload_var_dump cannot be altered with ini_set() at runtime

0000861: Describe encoding of the 'fileuri' parameter in DBGp

Sat, 23 Mar 2013 14:50:07 +0000

The encoding format of 'fileuri' is actually not documented here - xdebug.org/docs-dbgp.php

Recently I've tried several ways:
1) URL encoding - doesn't work
2) Rule for all message packets (http://xdebug.org/docs-dbgp.php#message-packets [^]) - doesn't work
3) Escaping of ' ' and '%' - works.

Please clarify the official position in the documentation

Thanks!
