Summary0007220: 0-inventory product increased after order declined/canceled

A partner payment provider (Ratepay) reported to us that it seems to be a strange behavior with article with 0 stock, when an order goes wrong.

The article with 0 stock can still be ordered (depending on the shop configuration). As normal process, the stock is reduced by -1, but when no negative stock is allowed, the value stays at 0.

Then when the order goes wrong, the stock is increased by 1, as a way to restore the initial stock.

Problem is that the stock is now 1, when it was initially 0.

To make sure that the problem doesn't come from the module, I tried on vanilla shop, with standard payment methods.
After the order was successfully placed, I cancelled it in admin, and noticed the same behavior (stock =1 when it was 0 before)

Thanks for help.

Steps To Reproduce- Set a product to oxstock = 0

- Delivery status = standard

- Place an order with whatever oxid standard payment method

- After order placement, in admin > order management > cancel the order (via the option at the end of the line for example)

- Check the stock amount of the article, it will be set to 1 instead of 0.
Additional InformationFor standard methods, I could not achieve a "declined" order as it is with the payment plugin. They have specific test data that allow the payment to be simulated as declined.

But the anomaly (if it is) can also be observed with a cancelled order.

I noticed the same behavior in a 4.10.8 shop Version.

I've seen a similar issue there :

If the stock level of an item oxstock = 0 and is ordered, the stock level will be decremented only if in the master settings -> core settings -> settings -> stock -> "Allow negative Stock Values" is enabled, otherwise it remains = 0.

1. So oxstock = 0
2. Master settings -> core settings -> settings -> stock -> "Allow negative Stock Values" is enabled
3. Article will be oredered -> oxstock = -1
4. If "Allow negative Stock Values" is not enabled -> oxstock remains 0

If the order is now cancelled, the corresponding oxstock is incremented and leads to oxstock = 1 if "Allow negative Stock Values" is not activated, and to oxstock = 0 if "Allow negative Stock Values" is activated.

Therefore the bug is closed.
