Exposes two options, `path` and `mode`, to configure the location and
permissions on the socket file.
The `mode` needs to be specified as string in octal and will be converted
into a decimal integer, so it correctly passes through the YAML parser
and arrives at the `os.chmod` call in the Twisted codebase. What a fun
detour.
Adds an assertion, that either `path` or `bind_addresses` and `port` are
configured on every listener.
Migrates the default replication listener of the main instance to a UNIX
domain socket, because it is more efficient.
Introduces the `enableRegistrationScript` option, to gracefully disable
the user registration script, when the client listener listens on a UNIX
domain socket, which is something the script does not support.
The current build of livebook does not work with the new [Livebook
Teams](https://livebook.dev/teams/) features. The problem can be observed by
running the current version of livebook, adding a new team and going to the team
page. The process will crash and the team page will show a 500 error.
The base of the problem is that the escript build method is not officially
supported. This commit changes the livebook package to use the `mix release`
workflow, which is also the one used to build the official Docker container.
Unfortunately, the binary built with `mix release` does not support command line
arguments like the `escript` binary does. Instead, users need to pass in most of
the configuration as environment variables, as documented
[here](https://hexdocs.pm/livebook/readme.html#environment-variables). As a
result, this commit also changes the Livebook service to reflect this new way of
configuring Livebook.
Finally, the Livebook release configuration specifically excludes the
ERTS (Erlang Runtime System), which means that the resulting release cannot run
without Erlang installed.
I have tested the results (both of the package and the service) locally.
It is probably a good idea to talk about it and leave it to release editors to decide how they want to present this.
Hardware OPAL based is interesting for certain companies with compliance constraints.
There were several modules, critically including NetworkManager, which
were not prepared for this change. Most of the change was good,
however. Let's bring back the dependency and change the assertion to a
warning for now.
