Add barebones but working implementation of model preload
* add config test for Preload hook
* improve TestProxyManager_StartupHooks
* docs for new hook configuration
* add a .dev to .gitignore
* Add endpoint aliases for reranking models
* Add MetricsMiddleware to the previous reranking endpoint
* Fix the embeddings endpoint not having model set
Allow configuration of how a model is stopped before swapping. Setting `cmdStop` in the configuration will override the default behaviour and enables better integration with other process/container managers like docker or podman.
Add automatic port numbers assignment in configuration file. The string `${PORT}` will be substituted in model.cmd and model.proxy for an actual port number. This also allows model.proxy to be omitted from the configuration.
Groups allows more control over swapping behaviour when a model is requested. The new groups feature provides three ways to control swapping: within the group, swapping out other groups or keep the models in the group loaded persistently (never swapped out).
Closes#96, #99 and #106.
This change revamps the internal logging architecture to be more flexible and descriptive. Previously all logs from both llama-swap and upstream services were mixed together. This makes it harder to troubleshoot and identify problems. This PR adds these new endpoints:
- `/logs/stream/proxy` - just llama-swap's logs
- `/logs/stream/upstream` - stdout output from the upstream server
* Adds an endpoint '/running' that returns either an empty JSON object if no model has been loaded so far, or the last model loaded (model key) and it's current state (state key). Possible state values are: stopped, starting, ready and stopping.
* Improves the `/running` endpoint by allowing multiple entries under the `running` key within the JSON response.
Refactors the `/running` method name (listRunningProcessesHandler).
Removes the unlisted filter implementation.
* Adds tests for:
- no model loaded
- one model loaded
- multiple models loaded
* Adds simple comments.
* Simplified code structure as per 250313 comments on PR #65.
