| Summary | 0010478: merchant backend crashes when making a donation after donau changed its keys | ||||
| Description | We don't have a good reproducer for this yet. It happened on test.taler.net after purging the donau DB (since the donau DB had a breaking change). | ||||
| Additional Information | Oct 07 17:29:35 cceb10198446 taler-merchant-httpd[3289]: (QJ21HG08EW9Y3JA9TQ3GT9D100) ERROR Assertion failed at donau_api_handle.c:774. Oct 07 17:29:35 cceb10198446 taler-merchant-httpd[3289]: (QJ21HG08EW9Y3JA9TQ3GT9D100) WARNING External protocol violation detected at taler-merchant-httpd_post-orders-ID-pay.c:3385. | ||||

9a96cbf..f75bf8c fixes an incorrect return value in libdonau. |
|
|
64d52a6e..141b6bb6 improves the error handling in the merchant backend. However, I didn't see any actual CRASH here, just an error that should have been a warning (client uses different donau keys than what we have, so we cannot sign). |
|
|
Note that when Donau keys change and wallet/merchant/donau disagree on what they should be, things are expected to go to hell (aka 400) until that is resolved. |
|
|
Let me know if you see more being required here. |
|
|
Needs a test IMO, I can add one to taler-harness. |
|
|
We have a test now: $ taler-harness run-integrationtests donau-keychange However, the test actually does crash the merchant. |
