Summary0006581: long polling on /orders/{order_id} must return when already_paid_order_id becomes available [test needed]
DescriptionCurrently, the request blocks even if the wallet pays for the same fulfillment_url in the current session for an existing order.

This causes the re-purchase detection flow to now work unless the page is manually refreshed.
TagsNo tags attached.

Assuming this was in conjunction with a /paid request, this should be fixed in f19e58b..229fbc1.

I looked at the /pay code, there it seems everything was already OK.

Did NOT test, as I am not sure what you did to produce the issue in the first place.

Florian reports this is fixed.

It's actually not! I still have to manually refresh the page, as the long-polling request made by the JavaScript on the page doesn't return.

(To reproduce, but article on, delete cookies, refresh page, pay again. Instead of the page auto-refreshing, you have to refresh manually after scanning the QR code. Looking at the dev tools, the long-polling request doesn't return a response, even though it should!)

I've implemented a fix for this in 7302e0c..e12f64d. Untested, and needs testcase.

I will test next, and if it works this will do for 0.8.0.

Jonathan: please (eventually) implement a test for this in test_merchant_api.c (for 0.8.1) -- we don't want to see regressions on this stuff!

Ok, finally got it to work. Jonathan: please do write tests with good coverage for the repurchase detection logic.
