Add support for multiple Deadline ☠️➖ servers

[antirotor]

Feature

This is adding support for multiple Deadline servers for OpenPype 3.

Changes in Settings

Deadline Module in System Settings now have ability to specify multiple keys for Deadline URLs. default is changeable but cannot be deleted and is used through pipeline if nothing else is defined.

In Project Settings -> Deadline there is now multiselect enum that allows setting specific Deadline Servers for project.

Publishing

It is up to Creator in specific host how it will handle this feature. Currently implemented in Maya it uses this code to get available servers for project:

from openpype.api import get_system_settings, get_project_settings
from openpype.modules import ModulesManager
from avalon.api import Session


deadline_settings = get_system_settings()["modules"]["deadline"]
if not deadline_settings["enabled"]:
    deadline_servers = {}
    return

project_settings = get_project_settings(Session["AVALON_PROJECT"])
try:
    default_servers = deadline_settings["deadline_urls"]
    project_servers = project_settings["deadline"]["deadline_servers"]
       
    deadline_servers = dict(
        (k, default_servers[k])
        for k in project_servers if k in default_servers)
        
except AttributeError:
    # Handle situation when we had only one url for deadline.
    manager = ModulesManager()
    deadline_module = manager.modules_by_name["deadline"]
    # get default deadline webservice url from deadline module
    deadline_url = deadline_module.deadline_url
    deadline_servers = {"default": deadline_url}

In the rest of the publishing pipeline - in publish plugins you can get default Deadline URL from context:

context.data["defaultDeadline"]

🗒️ this is now collected by new collector*

Support for this was added to all Deadline plugins but it needs host specific initial entry point (probably in render instance creator) to allow user to select desired server. That is currently implemented only in Maya.

Is it ok to require access to deadline server to be able create render?

• I can't create the instance in home and then send it to studio...

It seems there are added callbacks to changes of comboboxes (not sure as I couldn't create because of missing deadline). I'm not sure how callbacks would work after reopening scene?
