Description
Observation¶
https://openqa.opensuse.org/tests/1214224 is incomplete with
[2020-03-26T10:30:40.005 CET] [debug] running /usr/bin/qemu-img info --output=json openSUSE_Krypton.x86_64-5.12.80-Build16.72.iso
[2020-03-26T10:30:40.013 CET] [debug] qemu-img: Could not open 'openSUSE_Krypton.x86_64-5.12.80-Build16.72.iso': Could not open 'openSUSE_Krypton.x86_64-5.12.80-Build16.72.iso': No such file or directory
[2020-03-26T10:30:40.013 CET] [debug] Backend process died, backend errors are reported below in the following lines:
malformed JSON string, neither tag, array, object, number, string or atom, at character offset 0 (before "qemu-img: Could not ...") at /usr/lib/perl5/vendor_perl/5.26.1/Mojo/JSON.pm line 39.
while the root cause of the iso image not being existant is one issue this ticket should focus on incorrect parsing of a simple error string as JSON.
Acceptance criteria¶
- AC1: An error string from qemu-img is not causing an error trying to parse as JSON
Suggestions¶
- Check where the output of qemu-img is gathered and how it could end up being parsed as JSON
- Ensure that only valid JSON output if any is tried to be parsed as JSON, probably in the qemu backend
- Ensure the error message is output in a way that is readable by human: As the output of qemu-img is already correctly shown in the output maybe it is as easy as not trying to parse anything and return with an error code without trying to do more
