andrijapanicsb commented on issue #3383: [WIP DO NOT MERGE] template: copy md5 
mismatch
URL: https://github.com/apache/cloudstack/pull/3383#issuecomment-562105795
 
 
   As discussed (internally) this fix simply set the source image md5sum to 
NULL (instead of reading a wrong md5sum from DB, from the compressed file) and 
thus when SSVM receives the files in the new zone, since no source MD5 sum was 
defined, it will not check and will consider an image as downloaded 
successfully - which should be fine in 99% of cases.
   
   I would like to test a silly thing - if the download of template (via the 
SSVM in the destination zone) is somehow interrupted - do we ever reach the MD5 
"to check or not to check" part of code - ideally the download process should 
break and no false positive in sense of "successful" download.
   
   This can be tested while copying a template from zone1 to zone2, by logging 
in to zone1 SSVM and simply stopping the Apache webserver - simulating 
connection drop - and checking/confirm that on the destination zone the 
template download has broken as exected.
