Basic Idea

The idea is to add another parameter to the function RPCCLient as:

client = oslo_messaging.RPCClient(transport, target, options={'mandatory': True})
client.call({}, 'foo', id_value=str(i), test_value="hello oslo")

Inside the function, _publish decode the option value, as:

Generate a certificate

Note: Git Bash comes with OpenSSL

$ openssl req -x509 -new -newkey rsa:4096 -sha256 -days 730 -nodes -out freenode.pem -keyout freenode.pem
Generating a 4096 bit RSA private key
.....................................................++
............................................................................++
writing new private key to 'freenode.pem'

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.

Using OTP's observer (appmon replacement) remotely

$ ssh remote-host "epmd -names"
epmd: up and running on port 4369 with data:
name some_node at port 58769

Note the running on port for epmd itself and the port of the node you're interested in debugging. Reconnect to the remote host with these ports forwarded:

$ ssh -L 4369:localhost:4369 -L 58769:localhost:58769 remote-host

	"""Proof of concept of an adapter that will wrap a blocking IO library in
	greenlets, so that it can be invoked by asyncio code and itself make calls out
	to an asyncio database library.

	hint: any Python ORM or database abstraction tool written against the DBAPI
	could in theory allow asyncio round trips to a pure async DB driver like
	asyncpg.

	The approach here seems too simple to be true and I did not expect it to
