|Reporter||Florian Dold||Assigned To||Florian Dold|
|Priority||high||Severity||crash||Reproducibility||have not tried|
|Product Version||SVN HEAD|
|Target Version||0.5||Fixed in Version||0.5|
|Summary||0005273: taler-exchange-wirewatch does not handle row id sizes correctly|
|Description||last_row_off_size in taler-exchange-wirewatch is read but never written (it's static so initialized to zero).|
This lead to the crash below, which we resolved for now by resetting the exchange database.
|Steps To Reproduce||demo-blue@tripwire:~$ taler-exchange-wirewatch -t test|

Eh, I don't see this. It is intentionally left at 0 initially, unless get_latest_reserve_in_reference() succeeds. Overall, whenever we update "last_row_off", we also update last_row_off_size. There was one case on shutdown which did not reset last_row_off_size to 0 which I fixed.
I also found and removed a totally bogus GNUNET_break() in cb623d4..61fbc32.
There was clearly something wrong in the old code, maybe you were looking at the wrong "original" version? See this:
The variable last_row_off_size was never written to in that file. And it's a static global, so it's *always* equal to zero, which certainly is not what you intended!
There was also some additional start_off, which made things more confusing (which AFAIK lead to some bug with the reset mode, I might misremember though).
(the GNUnet break you removed was bogus though!)
||Well, I see the issues in the old code, but regardless, the code right now looks fine, so clearly this bug should have been resolved, right?|
||Yes, it should've been resolved!|
