How do I debug an Atompub POST sent via cURL to Wordpress on XP + Apache 2.2 + XDebug

Question

I've been using NetBeans as the XDebug interactive debugging client. But seems like it only supports attaching debuggers to scripts that are invoked via Firefox. I want to step through the request parse script when it's invoked via cURL.

Answer 1

I figured out the answer. First I attached a debugger by right-clicking on the wordpress project in netbeans and choosing "debug". This will open the blog in firefox with the "XDEBUG_SESSION_START=netbeans-xdebug" param included in the url (e.g. "http://localhost/wordpress/?XDEBUG_SESSION_START=netbeans-xdebug").

Then I invoked cURL from the command line, making sure to set a cookie with the name/value XDEBUG_SESSION/netbeans-xdebug:

>curl "http://localhost/wordpress/wp-app.php/posts" -X POST -H "Content-type: application/atom+xml" -v -L -k -u admin:password --data @post_atom_entry_bad.xml -o post_bad_response.txt -b XDEBUG_SESSION=netbeans-xdebug

*   Trying 127.0.0.1... connected
* Connected to localhost (127.0.0.1) port 80 (#0)

} [data not shown]
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   302    0     0    0   302      0     74 --:--:--  0:00:04 --:--:--     0

At this point cURL halts at the breakpoint I have set at line 283 in wp-app.php, AtomParser->handle_request(), and I can step through the code.

Once I click F5 (continue), the server sends the response back to cURL:

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

Done. Would be great to get examples from other interactive debugging clients like notepad++.
