Refactor code to support starting of multiple back end llama.cpp servers. This functionality is exposed as `profiles` to create a simple configuration format.
Changes:
* refactor proxy tests to get ready for multi-process support
* update proxy/ProxyManager to support multiple processes (#7)
* Add support for Groups in configuration
* improve handling of Model alias configs
* implement multi-model swapping
* improve code clarity for swapModel
* improve docs, rename groups to profiles in config
* Make starting upstream process on-demand (#10)
* Add automatic unload of model after TTL is reached
* add `ttl` configuration parameter to models in seconds, default is 0 (never unload)
- Add a check to return immediately if the write buffer is empty
- Create a copy of new history data to ensure it is immutable
- Update the `GetHistory` method to use the `any` type for the buffer interface
- Add a test case to verify that the buffer remains unchanged
even if the original message is modified after writing
Improvements to handling of the upstream process so errors happen whenever one of these is first:
the health check timeout is reached waiting for the upstream process to be ready
the upstream process exits unexpectedly
With this change llama-swap is more compatible with use cases like containerized upstream services (#5) which pull the container before HTTP endpoints are ready.
llama-swap only waited a maximum of 5 seconds for an upstream
HTTP server to be available. If it took longer than that it will error
out the request. Now it will wait up to the configured healthCheckTimeout
or the upstream process unexpectedly exits.
Replace previously hardcoded value for /health to check when the server became ready to serve traffic. With this the server can support any server that provides an an OpenAI compatible inference endpoint.
