| Summary | 0004794: assertion failing on withdraw | ||||
| Description | Nov 17 12:03:25-489866 taler-exchange-httpd-24247 ERROR Assertion failed at plugin_exchangedb_postgres.c:2014. Nov 17 12:03:25-489892 taler-exchange-httpd-24247 ERROR Assertion failed at taler-exchange-httpd_db.c:795. Some internal amount check is failing: if (GNUNET_SYSERR == TALER_amount_subtract (&reserve.balance, &reserve.balance, &collectable->amount_with_fee)) { /* Should have been checked before we got here... */ GNUNET_break (0); goto cleanup; } Likely due to a change in the fee structure. | ||||

Should be fixed in bb7c589..e140ca9, based on the assumption that this was caused by a wallet doing parallel withdraws and going over balance at the same time based on the 1e8/1e6 amount fraction change. |
|
|
Fix committed to master branch. |

handle more nicely the case that concurrent withdraws have changed history, causing us to see a different balance just before the commit; in this case, just retry the transaction; this should fix 0004794 |
