Debug logs Undefined index: txn_type, random API calls from Paypal 173.0.81.1

I have a mongrel 156-157 site.
I have Report All Errors on permanently (NoDups) and have no errors apart from these.

I get a block of these (like 9 over 45 minutes) with identical errors. The originating IP address is a Paypal site/appears to be legit.
There does not appear to be any relation to any orders: an order may occur in the midst of these, or not at all.

My query is if anyone else has Report All Errors enabled on a production site?
Unlikely on a 156 site as it is a pile of work to clear the inherent errors to zero, and unlikely that there is a ZC157 (which has most errors fixed) in production/being used for Paypal tests....although this issue appears to be unrelated to Paypal orders.

Is it possible Paypal is making these calls for its own purposes...but no-one has noticed, due to the above reasons?

In the following debug, the final error for Call to undefined function zen_update_orders_history
I don't get. As the function exists and other functions in the same file are used previously/so file is proven to have been loaded.

I have modified the debug to show more details, there is no-one logged in on this session.

While I haven't (yet) located when /includes/auto_loaders/paypal_ipn.core.php was updated for zc157, it sounds like you need to add the following line

Code:

---

  $autoLoadConfig[60][] = array('autoType' => 'require',
                                'loadFile' => DIR_WS_FUNCTIONS . 'functions_osh_update.php');

---

... just prior to the auto-load for DIR_WS_FUNCTIONS. 'functions_general.php'. Those are most likely PayPal IPNs coming back with status updates, maybe?

Noting that the zc157 version of the /ipn_main_handler.php was updated to use the zen_update_orders_history function; you've apparently pulled that version in without the above change to its auto-loader.

Thanks!


I have had to add a few other checks in the ipn_handler for php notices...I would hope someone is doing nit-picking real transactions with ZC157 trap these notices...

That fix did clear the fatal error.

The other notices remain...to be seen if they are squashed in ZC157!
