feat(cloud_server): implement SSL secure websocket from semver2 into semver3

[Boss-1s]

Resolves nothing

Changes

• Implemented SSL secure ws server (fix cloud server #658) from semver2 into semver 3

• New class _SaWebSockectServer BaseWebSocketServer in sa.eventhandlers._base to keep things pythonic and organized

• You can now link a cloud

• refactoring everything related cause why not

Tasks

• implement
• clean up to match semver3 logic
• feat(cloud_server): implement SSL secure websocket from semver2 into semver3 #723 (comment)
• feat(cloud_server): implement SSL secure websocket from semver2 into semver3 #723 (comment)
• could be more, we may need @faretek1 's thoughts on this as well

Tests

First, start up an insecure server to ensure it works:

import scratchattach as sa
from scratchattach.cloud.cloud import CustomCloud
import logging
from rich.traceback import install

install(show_locals=True)

# Init Server & Cloud Events

server_ip = '127.0.0.1'
server_port = 8080
project_id="1321224718"

server = sa.init_cloud_server("127.0.0.1",
                              server_port,
                              length_limit=65536,
                              allow_non_numeric=True,
                              whitelisted_projects=[project_id],
                              allow_nonscratch_names=False,
                              blocked_ips=["127.0.0.2"],
                              sync_players=True,
                              log_var_sets=True
                              )
server.start()


banned_cloud = CustomCloud(project_id='1234567',
                    cloud_host=f"ws://{server_ip}:{server_port}",
                    username = "Boss_1s",
                    length_limit = None,
                    allow_non_numeric = True,
                    _session = None,

                    cookie = None,
                    origin = None,
                    print_connect_messages = True
                    )

                    origin = None,
                    print_connect_messages = True
                    )

cloud = CustomCloud(project_id=project_id,
                    cloud_host=f"ws://{server_ip}:{server_port}",
                    username = "Boss_1s",
                    length_limit = None,
                    allow_non_numeric = True,
                    _session = None,
                    header = None,

                    origin = None,
                    print_connect_messages = True
                    )

no_user_cloud = CustomCloud(project_id=project_id,
                    cloud_host=f"ws://{server_ip}:{server_port}",
                    username = None,
                    length_limit = None,
                    allow_non_numeric = True,

                    origin = None,
                    print_connect_messages = True
                    )

                    print_connect_messages = True
                    )

While the above script is running, run websocat ws://127.0.0.1:8080 to interact with the websocket.

Once you have determined that this works, replace the above script with the one below:

import scratchattach as sa
from scratchattach.cloud.cloud import CustomCloud
import logging
from rich.traceback import install

install(show_locals=True)

# Init Server & Cloud Events

server_ip = '127.0.0.1'
server_port = 8080
project_id="1321224718"

# Test with ssl and make sure it works

server = sa.init_ssl_cloud_server("127.0.0.1",
                              server_port,
                              length_limit=65536,
                              allow_non_numeric=True,
                              whitelisted_projects=[project_id],
                              allow_nonscratch_names=False,
                              blocked_ips=["127.0.0.2"],
                              sync_players=True,
                              log_var_sets=True,
                              certfile="certfile.pem",
                              keyfile="keyfile.pem"
                              )
server.start()


banned_cloud = CustomCloud(project_id='1234567',
                    cloud_host=f"wss://{server_ip}:{server_port}",
                    username = "Boss_1s",

                    allow_non_numeric = True,
                    _session = None,

                    )

bad_user_name_cloud = CustomCloud(project_id=project_id,
                    cloud_host=f"wss://{server_ip}:{server_port}",
                    username = "Boss_asdfghjkl",

                    print_connect_messages = True
                    )

cloud = CustomCloud(project_id=project_id,
                    cloud_host=f"wss://{server_ip}:{server_port}",
                    username = "Boss_1s",

                    )

no_user_cloud = CustomCloud(project_id=project_id,
                    cloud_host=f"wss://{server_ip}:{server_port}",
                    username = None,
                    length_limit = None,
                    allow_non_numeric = True,

                    cookie = None,
                    origin = None,

                    origin = None,
                    print_connect_messages = True
                    )

banned_cloud_events=banned_cloud.events()
bad_user_name_cloud_events=bad_user_name_cloud.events()
cloud_events=cloud.events()
no_user_cloud_events=no_user_cloud.events()
no_project_cloud_events=no_project_cloud.events()

Then, generate an OpenSSL certificate:

openssl req -x509 -newkey rsa:4096 -keyout keyfile.pem -out certfile.pem -days 365 -nodes

Finally, run the server script, and interact with the WebSocket with websocat -k wss://127.0.0.1:8080

Notes

might wanna have #722 fixed before merging this, idk

[Boss-1s]

@TheCommCraft

[TheCommCraft]

Tell me if you require help in applying these changes

[Boss-1s]

Should we add documentation or something of the sort for this argument?

[TheCommCraft]

serveforever is implemented with a while loop of serveonce

[TheCommCraft]

I think that the custom cloud solution you added might cause extreme lag, it would be better to just not add a cloud at first (or you could create a cloud that just translates method calls of the cloud into those of the server)

[Boss-1s]

The only thing left is the set var prefix option, then we should be done here
