The tunnel, the fence, the registry and the relay were all built and none of them carried a byte: every dial from the frontend still went to the address a worker registered. This is where that stops. One WorkerDialer resolves where a worker's tunnel is held, opens a stream on it locally or relays through the owning replica, and hands back a conn past both handshakes; gRPC, the file stager's HTTP client and the log-streaming WebSocket are all pointed at it. A worker's address stops being somewhere to connect to and becomes the name of which backend process a stream is for. It still appears in URLs, logs and errors, because that is what identifies the process; what it no longer decides is where the bytes go. Nothing falls back to dialling it. BackendClientFactory now has exactly one method, NewClientForNode, and returns an error where there is no way to reach the worker. The direct-dial constructor was removed rather than kept beside it, because leaving one on the interface keeps the bypass one word away from every call site that holds an address, which is all of them. The second construction path is closed too. DistributedModelStore built remote models with a nil client, and pkg/model.Model.GRPC then dialled the raw address lazily on first use - reached in production by ShutdownModel's Free and by the backend monitor's Status. Those models now carry the tunnel-backed client, and a model that cannot be given one is logged and not listed. Four conditions stay unmixable, and one path produces absence: the dialer answers ErrNoConnection only where Owner's liveness join did. A peer that will not answer, a stale ownership row, a worker's own refusal and a missing relay path are each reported as themselves. This matters because nodes ACTS on absence, and the collapse would have it reclaim the models of a worker that is connected and busy. That is not hypothetical. Writing the mutation for it exposed the bug in this change's own first draft: probeHealth returned bare false when it could not build a client, and tryWarmPath deletes the replica row on a false probe. A frontend whose dialer broke would have emptied node_models for the whole deployment while every model kept running. probeHealth now returns alive and probed separately, the reconciler gets a ProbeUnknown outcome that neither advances nor clears a failure streak, and the health monitor skips rather than counting a miss. Task 5 left the relay's open timeout at a fixed 15s and said so: no operator has the information to set it, because the number that matters is the original client's remaining budget, which is invisible on the relay side. The dialer has that budget, so it now states it in the relay request frame and the owner takes the smaller of the two. It can only shorten - a patient client must not be able to park a relay goroutine and a stream slot on a worker that stopped accepting. Zero is written as no budget at all, since on the far side the number zero is a caller with nothing left and would refuse healthy traffic. Seven mutations, each reddening a named spec: peer-unreachable as absence; the local-failure guard dropped; max instead of min on the budget; the nil-client model restored; ProbeUnknown falling through to the reaper; OwnerRow instead of Owner; probed collapsed into alive. The first budget spec passed for the wrong reason - a handshake deadline, not the relay - and was replaced by three that each assert one link, including one where the spec plays the owning replica and reads the budget out of the frame instead of inferring it from a clock.

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.
-
Build the docker image
docker-compose build -
Run the built image
docker-compose upNOTE: You can run both commands at once with
docker-compose up --build. -
Verify that the service is working.
Open your web browser and type
http://localhost:1313in 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 /

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.
