Ettore Di Giacinto 49128cf486 feat(distributed): keep the listener draining and let it come back
PostgreSQL holds undelivered notifications in a queue it shares with every
session on the server, and it kills a listener that stops draining. Two failure
modes follow, and both are silent: a carrier that blocked on a slow resolver
would lose its connection and with it every later broadcast, and a carrier that
reconnected without re-registering would be connected and deaf.

The receive and dispatch halves were already separate. What was missing is
everything around them. The listener path moves into listener.go and gains a
carrier-level Dropped() so a replica that is behind can be seen; the queue depth
and the spill retention become Config fields with exported defaults; the LISTEN
session gets an application_name so an operator can count listeners in
pg_stat_activity and a spec can drop exactly one of them; and OnReconnect fires
after the re-LISTEN, on a goroutine of its own, because a callback re-hydrates
from a database and must never run on the path whose only job is to drain.

That callback is reached through an optional interface assertion, so deleting
its invocation compiles and every adopter silently stops converging. The spec is
the only guard, and it is named in a comment at the site.

The slow consumer is proved through the transport rather than a seam: an ACCESS
EXCLUSIVE lock on bus_messages stalls the resolver's spill SELECT for exactly as
long as the spec holds it, and the listener is shown still draining and dropping
while it does. The dropped connection is a pg_terminate_backend matched on the
carrier's own application name.

Neither Dropped nor IsConnected is on messaging.Broadcaster, and a spec asserts
that over the interface type. Both are facts about a frontend; the conditions a
scheduler acts on are facts about a worker, and no consumer holding the
interface can read one as the other.

Requirement

In this project, the Docsy theme component is pulled in as a Hugo module, together with other module dependencies:

$ hugo mod graph
hugo: collected modules in 566 ms

If you want to do SCSS edits and want to publish these, you need to install PostCSS

npm install

Running the website locally

Building and running the site locally requires a recent extended version of Hugo. You can find out more about how to install Hugo for your environment in our Getting started guide.

From the LocalAI repository root, run:

make docs

The Hugo configuration lives in the docs directory. To invoke Hugo directly instead, run:

cd docs
hugo server

Running a container locally

You can run docsy-example inside a Docker container, the container runs with a volume bound to the docsy-example folder. This approach doesn't require you to install any dependencies other than Docker Desktop on Windows and Mac, and Docker Compose on Linux.

  1. Build the docker image

    docker-compose build
    
  2. Run the built image

    docker-compose up
    

    NOTE: You can run both commands at once with docker-compose up --build.

  3. Verify that the service is working.

    Open your web browser and type http://localhost:1313 in your navigation bar, This opens a local instance of the docsy-example homepage. You can now make changes to the docsy example and those changes will immediately show up in your browser after you save.

Cleanup

To stop Docker Compose, on your terminal window, press Ctrl + C.

To remove the produced images run:

docker-compose rm

For more information see the Docker Compose documentation.

Troubleshooting

As you run the website locally, you may run into the following error:

➜ hugo server

INFO 2021/01/21 21:07:55 Using config file: 
Building sites … INFO 2021/01/21 21:07:55 syncing static files to /
Built in 288 ms
Error: Error building site: TOCSS: failed to transform "scss/main.scss" (text/x-scss): resource "scss/scss/main.scss_9fadf33d895a46083cdd64396b57ef68" not found in file cache

This error occurs if you have not installed the extended version of Hugo. See this section of the user guide for instructions on how to install Hugo.

Or you may encounter the following error:

➜ hugo server

Error: failed to download modules: binary with name "go" not found

This error occurs if you have not installed the go programming language on your system. See this section of the user guide for instructions on how to install go.
