Order item quantity and total keep inflating

[Tea56]

I am seeing the quantity and total inflation when editing same order. (quantity is going up and sometimes a second instance of the product gets added.)

Just tried with a clean installation adding one of the demo products to cart and checking out.

Go to orders, edit. click next. then back, then next, now it's 2 quantity.
if you click on order again to edit, it's now 2 and gets more.

it's the last call
index.php?route=sale/order/api&token=...&api=api/cart/products&store_id=0 that keeps getting inflated results.
database is not affected. i am not familiar with curl, but curl response has the incremented quantity and total.

checked locally and on a live site.

I would appreciate some help. At least point me in the right direction.

thank you!

For what it's worth, it looks like multiple ControllerSaleOrder Controllers are getting instantiated.

The easiest to recreate it, is to edit order, continue, then back, continue and back and continue before the last ajax call finished. This will cause curl to cache the data and the quantity and totals double each time.

Without the fix (i honestly don't know if this is fixing it, but it works for me. like i said, no curl experience)
once the order is "messed up" it never goes back to the original quantity and total.

With the fix, even if the above scenario happens, when starting to edit from scratch, the original order quantity and totals are restored. i.e. the curl call is not cached.

So, in admin/controller/sale/order.php I added
curl_setopt($curl, CURLOPT_FRESH_CONNECT, 1);
$header = array("Cache-Control: no-cache");
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);

after each $curl = curl_init();

and closed curl in info() where it hasn't been closed.
curl_close($curl);

*attached, clean install from this repo, using existing products. the order was for only one item. when editing, the order doubles.

this was fixed in the last release. I think you are using an old 2.0

I am using 2.0.1.1
