rasql scale operation issue - segmentation fault
| Reported by: | Owned by: | ||
|---|---|---|---|
| Priority: | major | Milestone: | 8.4 |
| Component: | rasserver | Version: | 8.3 |
| Keywords: | Cc: | barboni@… | |
| Complexity: | Medium |
Description
We heave a 3d collection that, when accessed with certain scale operator values causes the rasdaman server to segment. Other scale operator values do not cause the issue.
Attached are the details of the segfault observed performing a wcps query on the collection (wcps-crashes-rasdaman.txt) and details about the performed queries and collection (rasql-scale-issue.txt)

I can not reproduce this bug on the latest rasdaman from git, with these commands:
$RASQL -q "insert into $COLL values marray x in [0:832,0:19305,148289:148303] values 1.0" $RASQL -q "select sdom(scale(m[458:535,5499:5654,148290:148290], [0:300,0:500,0:0] )) from $COLL as m" --out string

hello Dimitar
Unfortunately now I have not enough information to help you reproduce the problem.
I have observed that the segmentation fault usually happens with collection composed by float data. With char or RGB collection it seems that rescale works well.
I'm sorry but now i have not other additional info.

As I was fixing #144 I managed to reproduce the segfault as well, so a patch is pending that should fix this.
