Toshio Kuratomi	500de1f557	Remove hack for backwards compatible v2_playbook_on_start callback ... Just after release of 2.0.0 (in 2.0.0.1) we had a change to the API of callbacks without bumping the API version. We added the playbook to the arguments passed to the callbacks. This wasn't in the Tower callback at the time. In order to prevent breaking that callback we added a temporary hack to inspect the callback's API to decide if we needed to call it with arguments or not. We scheduled the hack for removal in January 2017. Since that's now past, removing the hack. Change signed off by matburt on the Tower side.	8 years ago
Steve Kuznetsov	0bc35354ce	Change `v2_playbook_on_start` logic to positively detect legacy plugins ... In order to support legacy plugins, the following two method signatures are allowed for `CallbackBase.v2_playbook_on_start`: def v2_playbook_on_start(self): def v2_playbook_on_start(self, playbook): Previously, the logic to handle this divergence checked to see if the callback plugin being called supported an argument named `playbook` in its `v2_playbook_on_start` method. This was fragile in a few ways: - if a plugin author did not use the literal `playbook` to name their method argument, their plugin would not be called correctly - if a plugin author wrapped their `v2_playbook_on_start` method and by doing so changed the argspec to no longer expose an argument with that literal name, their plugin would not be called correctly In order to continue to support both types of callback for backwards compatibility while making the call more robust for plugin authors, the logic can be reversed in order to have a positive check for the old method signature instead of a positive check for the new one.
