Debugging XML RPC posting from google docs

  • I’m having problems with XMLRPC posting from google docs. Although I have this working perfectly well in many cases, there are some docs which just fail. From the google side, it all looks fine. From the wordpress end, nothing. No posts appear, not even mangled ones.

    I’ve been struggling with trying to debug this, and been floored at the first hurdle. I’ve tried adding define( ‘WP_DEBUG’, true ); to wp-config.php. I’ve also tried setting $xmlrpc_logging = 1 in xmlrpc.php. But, for the life of me, I can’t find where this logging information goes. This is making me feel very stupid and minimising the chance of me debugging anything. Interestingly, xmlrpc_logging results in errors from google end, so something is clearly happening.

    Just to give my background, I am a reasonable hacker, but I have very little PhP or WordPress specific experience. I’m capable of debugging things, but I would very much appreciate a few pointers in on the general process. As I say, this is making me feel daft at the moment.

    Setup:

    WordPress 3 (a couple of different versions, tried it in several places).
    Ubuntu 10.10
    Google docs, erm, doesn’t have a version number.

    Thanks in advance.

  • Any rhyme or reason to the docs that fail? Odd that some would work while others disappear.

    On the XML-RPC logging, the logIO function uses that:
    $fp = fopen("../xmlrpc.log","a+");

    It might be generating errors if it can’t open the file for writing.

    We can’t work out any particular logic to documents that fail, except, of course, they are “real” documents rather than test ones and so much more complex. I tried a reasonable amount of blackbox testing to see whether I could figure it out. It’s just not enough; sadly, I can’t get anything out of google docs, so I need to debug the wordpress side.

    With “../xmlrpc.log” where is this being interpreted relative to? It occurred to me last night that this might be a permissions problem — initially I was expected the logs to go to apache. But this doesn’t seem to be the case.

    Incidentally, I did try this on a wordpress.com blog. Also fails, but this time with a strange an incomprehensible error code from google.

    Thanks for your help so far!

    Odd. Any chance the size of the document is making a difference? Have you checked your web server and PHP error logs while publishing from Google Docs to see if anything helpful is logged?

    The xmlrpc.log happens in xmlrpc.php, so it would be one directory up from there.

    Can you post the error message you got when trying to post to a WordPress.com blog?
