Bug #20549

Updated by Tomáš Strachota over 7 years ago

When a reboot fails for one or more hosts, api glues the error messages together and puts them into one message. It also prints details about exception class (Foreman::WrappedException) which makes it even worse to read. 

 We should remove the wrapped exception details and put each message on it's own line. 

 *Current response:*  
 <pre> Current situation :  

 ` 
 {"error" => { 
   "message" => "Errors during reboot: mac525400d8c85d: ERF50-4973 [Foreman::WrappedException]: Unable to reboot mac525400d8c85d via https://192.168.122.25:8443: Failed to open TCP connection to 192.168.122.25:8443 (No route to host - connect(2) for "192.168.122.25" port 8443) ([Errno::EHOSTUNREACH]: Failed to open TCP connection to 192.168.122.25:8443 (No route to host - connect(2) for...) mac52540022ab12: ERF50-4973 [Foreman::WrappedException]: Unable to reboot mac52540022ab12 via https://192.168.122.156:8443: Failed to open TCP connection to 192.168.122.156:8443 (No route to host - connect(2) for "192.168.122.156" port 8443) ([Errno::EHOSTUNREACH]: Failed to open TCP connection to 192.168.122.156:8443 (No route to host - connect(2) fo...)" 
   } 
 } 
 </pre> 


 *Expected result:* 

 The common messages should put status of each host on a single line. The response should also contain the data about failures in machine readable format. 
 <pre> 
 { "error" => { 
     "message" => "Errors during reboot:\n 
 Unable to reboot mac525400d8c85d via https://192.168.122.25:8443: Failed to open TCP connection to 192.168.122.25:8443\n 
 Unable to reboot mac52540022ab12 via https://192.168.122.156:8443: Failed to open TCP connection to 192.168.122.156:8443" 
     "host_details" => [{ 
       "name" => "mac525400d8c85d", 
       "error" => "Failed to open TCP connection to 192.168.122.25:8443" 
     },{ 
       "name" => "mac52540022ab12", 
       "error" => "Failed to open TCP connection to 192.168.122.156:8443" 
     }] 
   } 
 } 
 </pre> ` 

 It will enable for easier usage in scripts. Eg. hammer can use the 'host_details' for printing nicely formatted messages: Expected :  

 ` 
 <pre> 
 hammer discovery reboot --all 
 Could not reboot the host(s): 
   mac525400d8c85d: Failed to open TCP connection to 192.168.122.25:8443 
   mac52540022ab12: Failed to open TCP connection to 192.168.122.156:8443 
 </pre> 
 `
