Marcus Sorensen commented on CLOUDSTACK-5843:
---------------------------------------------
Looking at the code, it looks like it sends a command to the secondary storage
vm agent, which does a bunch of things (creates directory on the nfs secondary
storage to store the template, interrogates the remote url for things like
download size, etc) before jumping into a thread to do the download and
returning the sync command. It seems like this should be made async, and that's
probably easier rather than trying to keep it from doing those things before
returning.
> registering templates/isos should be either async or changed to non-blocking

> The call to register templates and isos does more than most sync calls do, it
> seems to talk to the ssvm and have it run commands that can potentially time
> out. I ran into this in a test system when we tried to register a template
> with a non-routable URL. The cloudstack API call just hung. I realize that
> there was a problem (ssvm could not reach the template host), but no sync
> call should do anything like this that would block.
