Distributed mode needs an operator to run a NATS cluster. This adds the carrier that replaces its fan-out half, so a deployment eventually needs PostgreSQL and its own HTTP listener and nothing else. pgbus holds one PostgreSQL session per replica, pinned for the life of the process because LISTEN registrations belong to one backend session and a pooled handle would lose them on the next checkout. Publishes go out on the pool with pg_notify. Subjects map onto a channel by their first token, from a closed set of roots. A subject outside the set is refused at publish AND at subscribe rather than mapped to a channel of its own: a channel name is capped at 63 bytes, and one LISTEN per job id would be unbounded. Refused rather than dropped, because a subject that goes nowhere and reports nothing is the class of defect this work exists to remove. PostgreSQL refuses a notify payload of 8000 bytes or more, and several subjects on this bus exceed that in normal operation: a job result carries a whole LLM output, a gallery progress event carries one entry per node. Those are written to a row and the notification carries the id. What is measured against the cap is the ENCODED notification, not the caller's payload, because the subject and the envelope travel too. The filter grammar is not respelled here. Subscribe asks messaging.ValidFilter and delivery asks messaging.SubjectMatches, which makes this the first production caller of a matcher that had only test doubles. New refuses a DSN that names a different database from the pool: that pairing publishes successfully, delivers nothing, on every replica, and reports no error anywhere. Nothing publishes on it and nothing subscribes yet. The construction is wired anyway, because the DSN has exactly one legitimate source and a setting that decides whether any broadcast is delivered should not be invented by whichever call site is migrated first. Delivery is at-most-once, like NATS core. Nothing downstream may read a message it did not receive as evidence about a node: a carrier that cannot deliver is not a worker that is gone.

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 /
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.
