------------------------------
Summary: Repeated vcld processes are forked for 'deleted'
processes which fail to initialize
Key: VCL-793
URL: https://issues.apache.org/jira/browse/VCL-793
Project: VCL
Issue Type: Bug
Components: vcld (backend)
Affects Versions: 2.3.2
Reporter: Andy Kurth
Assignee: Andy Kurth
Fix For: 2.4
When vcld tries to process a request in the deleted state and the
initialization of all the corresponding objects fails, the request state may be
left as 'deleted' after the process exits. This causes vcld to fork a process
over and over again.
This will occur if there is a problem which causes the provisioning object to
fail to initialize. As a result, State.pm::reservation_failed is called. This
has a condition at the beginning which calls is_request_deleted. This returns
true. The code then proceeds to only set the computer state to available and
leaves the request state intact.
This is a problem because the failure occurred before the request state was
even updated to pending. vcld keeps trying to fork processes, all of which
fail.
A solution would be to catch this and set the computer state to failed and the
request state to complete.
