Bug #6304
Updated by Tom Clegg about 7 years ago
Node.dns_server_update() in source:services/api/app/models/node.rb is currently vulnerable to the following race (fixable by using a tempfile library):
* Request handler A writes hostname.conf.tmp.
* Request handler B opens hostname.conf.tmp for writing.
* Request handler A issues the move command.
Catch only the expected exceptions on the various write and update operations (IOError and SystemCallError?), not unexpected ones.
A "dns update with dir configured, but no command configured" test should assert that the command file was not written after calling dns_server_update
