* Metadata: Better handling of floating cert-authenticated clients (Ticket #1030)Sol Jerome2011-08-111-1/+1
| | | | | | | | | | | | | | | | | | | From the ticket: A floating, cert-authenticated client can be not recognized properly by hostname if it resolves to an arbitrary name in reverse DNS. Background: Metadata.resolve_client, called from @exposed Core's methods, falls back to reverse DNS lookup for client's name, because the name is not preserved thanks to bailing off early from Metadata.AuthenticateConnection. (This issue can be related to #936.) This patch enables caching of client names for cert-based floating clients. Signed-off-by: Sol Jerome <sol.jerome@gmail.com>
* Created a new method to return a sorted list of plugins by type.Mike McCallister2011-07-221-41/+54
| | | | | | | | | | | | | | | | | | | | Replaced many list comprehensions in Core.py with a new method named plugins_by_type(), which does the same thing with an added twist: this new method also sorts the list of plugins by a new field named sort_order. It also uses the name of the plugin where the sort_order values are the same. This lets us control the processing sequence of plugins that need to build on the results of a plugin that runs prior to them. The immediate example is Deps, which should run after Packages has generated the full list of packages to be installed. Prior to this commit, it was impossible to control the order in which they ran. A future commit will (hopefully) take advantage of this capability. This commit also splits the Core.validate_data() method into two: one for validate_structures() and one for validate_goals(), instead of passing in a base class and using if logic. This approach seemed a little clearer to me.

* Fix nasty core hang, which would manifest itself as a lockup upon shutdown ↵Narayan Desai2009-10-021-1/+6
| | | | | | | | | | | | | | | | | | | for bcfg2-{server,info,admin} The root cause of this issue was our use of external threads. Without a channel for data requesting plugin (and hence thread) shutdown, plugin threads would continue, unabated, forever. This would cause the python interpreter to hang forever waiting for a futex. Added a new shutdown method to Bcfg2.Server.Plugin.Plugin which sets a state flag upon shutdown request. Plugin threads must cycle periodically, even if no work is available, to ensure that the shutdown flag is honored in a reasonable amount of time. Also, the shutdown method is triggered using atexit. This means that scripts may need to explicitly sys.exit or raise SystemExit, depending on circumstances. This addresses at least one, but probably more tickets, however I am currently offline. git-svn-id: https://svn.mcs.anl.gov/repos/bcfg/trunk/bcfg2@5472 ce84e21b-d406-0410-9b95-82705330c041
