Benson Wong 35193f82f1 proxy: add swap matrix with solver-based model swapping (#646)
Add a new swap matrix to supersede groups for running concurrent models.
The matrix uses a solver that picks the lowest cost evictions to make a
requested model available. This simple approach along with a very basic
DSL grammar can enable very complex swapping scenarios.

- add DSL parser for set expressions with & (AND), | (OR), (), +ref
- add MatrixConfig structs, validation, and topological sort for +ref
- add MatrixSolver with cost-minimizing swap decisions
- add Matrix runtime integrating solver with Process lifecycle
- integrate matrix into ProxyManager with if-branches at all endpoints
- update config.example.yaml and config-schema.json with matrix schema
- config enforces groups XOR matrix (cannot use both)

Benson Wong 24efdb76b1 config: add macro support for name and description fields (#578)
Extend macro substitution to the name and description fields of
ModelConfig, matching the behavior already present for cmd, proxy,
checkEndpoint, and filters.

- substitute global/model macros (including MODEL_ID) in name and
description
- substitute PORT macro in name and description when allocated
- validate no unknown macros remain in name and description after
substitution
- add tests for macro substitution, MODEL_ID, and unknown macro error

Benson Wong cc77139ff8 proxy,proxy/config: add global TTL feature (#554)
Add a new configuration parameter globalTTL that all models will
inherit. The default value is 0 which matches the currently
functionality to never automatically unload a model.

The model.ttl's default has changed to -1, which means use the global
TTL value. Any model.ttl >=0 is now value with 0 meaning never unload.
This allows a model to override a globalTTL > 0 and be configured to
never unload.

Benson Wong 19fb5f35e9 proxy: implement setParamsByID filter (#535)
Add setParamsByID filter that applies different request parameters based
on the requested model ID, enabling per-alias behaviour for a single
loaded model.

- add SetParamsByID field to Filters struct and SanitizedSetParamsByID
method
- substitute ${MODEL_ID} and other macros in setParamsByID keys and
values
- validate no unknown macros remain in keys or values after substitution
- apply setParamsByID in proxyInferenceHandler after setParams (can
override it)
- update config-schema.json with setParamsByID definition
- update UI to show aliases and make them selectable in the Playground

Benson Wong b5fde8eb6d proxy,ui-svelte: add request/response capturing (#508)
Add saving request and response headers and bodies that go through
llama-swap in memory.

- captureBuffer added to configuration. Captures are enabled by default.
- 5MB of memory is allocated for req/response captures in a ring buffer.
Setting captureBuffer to 0 will disable captures.
- UI elements to view captured data added to Activity page. Includes
some
QOL features like json formatting and recombining SSE chat streams
- capture saving is done at the byte level and has minimal impact on
llama-swap performance

Benson Wong cdea7d16bd proxy/config: skip env macros in YAML comment lines (#496)
Fix a bug where ${env.macro_not_exist} in comments would trigger a non-substituted macro error.

Benson Wong 4e850c2834 config: refactor macro substitution in configuration (#470)
This commit simplifies substitution of environment variables into the configuration. There was a lot of repetitive code substituting ${env.VAR_NAME} into different fields after the configuration was parsed into a config.Config. This refactor uses a string substitution of env vars into the YAML config before it is fully parsed. This eliminates a lot of logic while maintaining backwards compatibility.

Benson Wong 75fced579e config: support macros in peer apiKey and filters (#469)
* config: support environment variable macros in peer apiKeys

Add ${env.VAR_NAME} substitution for peer apiKey fields, consistent
with existing env macro support for model fields and global apiKeys.

- Add env macro substitution for peers.{name}.apiKey in LoadConfigFromReader
- Add tests for peer apiKey env substitution
- Update config.example.yaml to show env macro usage

* config: support macros in peer apiKey and filters

Extend macro substitution to peer configuration fields:
- peers.{name}.apiKey supports both global macros and env macros
- peers.{name}.filters.stripParams supports both macro types
- peers.{name}.filters.setParams supports both macro types

Also renamed validateMetadataForUnknownMacros to validateNestedForUnknownMacros
for reuse across model metadata and peer filters validation.

Benson Wong 8f2137c72b config: support environment variable macros in apiKeys (#467)
Add substituteEnvMacros support for apiKeys configuration field,
allowing API keys to be loaded from environment variables using
the ${env.VAR_NAME} syntax.

- Apply env macro substitution before validation
- Add tests for env macro substitution in apiKeys

Benson Wong 124007cc98 config: add environment variable macros (#466)
* config: add environment variable macros

Add support for ${env.VAR_NAME} syntax to pull values from system
environment variables during config loading.

- env macros processed before regular macros (allows macros to reference env vars)
- works in cmd, cmdStop, proxy, checkEndpoint, filters.stripParams, metadata
- returns error if env var is not set
- add comprehensive tests

fixes #462

* docs: add env macro example to config.example.yaml

Benson Wong 22e098ac8b Add Peer Model Support (#438)
This PR allows a single llama-swap to be the central proxy for models served by other inference servers. The peer servers can be another llama-swap or any API that supports the /v1/* inference endpoint.

Updates: #433, #299
Closes: #296

Benson Wong 565c44766d config,proxy: add new configuration logToStdout (#432)
The new logToStdout option controls what is logged to stdout. The
default has been changed to just the proxy logs, which contain swap and
http request logs.

There are four supported settings: none, proxy, upstream, both. The
"both" setting is the legacy setting where everything was spewed to
stdout.

Benson Wong a89b803d4a Stream loading state when swapping models (#371)
Swapping models can take a long time and leave a lot of silence while the model is loading. Rather than silently load the model in the background, this PR allows llama-swap to send status updates in the reasoning_content of a streaming chat response.

Benson Wong 70930e4e91 proxy: add support for user defined metadata in model configs (#333)
Changes: 

- add Metadata key to ModelConfig
- include metadata in /v1/models under meta.llamaswap key
- add recursive macro substitution into Metadata
- change macros at global and model level to be any scalar type

Note: 

This is the first mostly AI generated change to llama-swap. See #333 for notes about the workflow and approach to AI going forward.

Benson Wong 1f6179110c proxy/config: add model level macros (#330)
* proxy/config: add model level macros

Add macros to model configuration. Model macros override macros that are
defined at the global configuration level. They follow the same naming
and value rules as the global macros.

* proxy/config: fix bug with macro reserved name checking

The PORT reserved name was not properly checked

* proxy/config: add tests around model.filters.stripParams

- add check that model.filters.stripParams has no invalid macros
- renamed strip_params to stripParams for camel case consistency
- add legacy code compatibility so  model.filters.strip_params continues to work

* proxy/config: add duplicate removal to model.filters.stripParams

* clean up some doc nits

Benson Wong 216c40b951 proxy/config: create config package and migrate configuration (#329)
* proxy/config: create config package and migrate configuration

The configuration is become more complex as llama-swap adds more
advanced features. This commit moves config to its own package so it can
be developed independently of the proxy package.

Additionally, enforcing a public API for a configuration will allow
downstream usage to be more decoupled.
