#119 204 when scan fails

[Olli Ihamäki]

I get 204 when c-icap fails to connect clamd via socket during c-icap startup.

Steps to reproduce:
two ways,
wrong startup order

1. prerequisities: working clamd/c-icap installation. Tested with CentOS 7 system
2. disable clamd and c-icap services
3. reboot system
4. start c-icap and wait until it fully starts
5. start clamd
6. test using c-icap-client with eicar or actual virus file
   • actual result: 204, and "Registry 'virus_scan::engines' does not exist!" and "Antivirus engine is not available, allow 204" mesages on server.log
     expected result: blocks file

c-icap does not have access to socket

1. install clamav and c-icap, run as different users , use socket connection
2. make sure that c-icap does not have access to clamd socket
3. test using c-icap-client with eicar or actual virus file
4. actual result: 204, and "Registry 'virus_scan::engines' does not exist!" and "Antivirus engine is not available, allow 204" mesages on server.log
   • expected result: blocks file
