Summary	0006028: operation gets stuck when repeating withdraw 10 times
Description	.
Steps To Reproduce	0. open app 1. click "Withdraw testkudos" and wait until operation is finished 2. repeat 1. about 10 times at some point the operation gets stuck, the withdraw button will stay greyed out. you can even wait 10 minutes and nothing will happen WORKAROUND: close app and open again. the operation will finish normally and you can start again. maybe you have to click on "retry pending operation" (which might be there because this issue is known?)

Florian Dold 2020-01-07 16:14 manager ~0015235	This is the request throttling feature of the wallet kicking in. We want to protect against bugs in the wallet accidentally DoS-ing our servers (or any server), so we have request throttling on a per-origin basis in the wallet networking layer. Restarting the wallet app manually resets request throttling. The real bug here is that the error ("request throttled") isn't shown properly in the pending operations.

Florian Dold 2020-09-04 11:56 manager ~0016843	Huh, there was actually a major bug in the token bucket implementation that the wallet uses to throttle request. This is fixed now, and in the Android App, dozens of "withdraw testkudos" requests work.
