1042120 - some SREG conversion targets complain of non-existent domain

Status: RESOLVED FIXED

Description

[Amy Rich [:arr] [:arich]]

When trying to convert a couple records into SREG, the conversion page gives the following error (where <number> is the pk of the record) before attempting to do the conversion:

Error while creating the SREG record.{'domain': [u'Model domain with pk <number> does not exist.']}


Here are two hosts that give that error:

When Inventory deletes an A record to make space for an SREG it will try to "prune" the domain tree, deleting any domain objects that have no records associated to them. In this case the A record with fqdn "buildbot-master117.bb.releng.use1.mozilla.com" is deleted and since its the only record in the "bb.releng.use1.mozilla.com" domain, that domain is deleted. When an attempt is made to save the sreg (who has, prior to the delete, had the "bb.releng..." domain assigned to it) the domain "bb.releng..." can not be found and the conversion fails.

There is a flag to pass to .delete() that tells it not to prune the tree. I've pushed a patch to Inventory and as soon as I push it to prod you should be able to convert the sreg successfully.
