"Free" represents the new era of open source development empowered by AI. Both freedom and free — the AI agent is not just free labor, it is like a copy of myself, or even tens of copies, all deeply understanding this project, how to deliver high-quality code, and how to serve the community. AI handles all the dirty work — the boring tasks, the documentation, the coding — and often does it better than I could, with ten times the power. We built an AI robot for the community to answer questions and help users learn this project, and we used AI to almost entirely rewrite the SRS Proxy server — its structure, its workflow — so that AI agents can comprehensively manage and maintain it. With AI I have power, and I have choice: no longer waiting for other developers to contribute, I am free to manage this project, freed from the labor of maintaining it alone. This is a fantastic, amazing new era for building and sustaining open source projects and communities.
Modernizes several `internal/*` packages under the Go proxy, replaces
third-party forks with standard-library primitives, and brings the
test suite from near-zero to high coverage across the touched packages.
Package changes
- **`internal/errors`** — Rewrites the `pkg/errors` fork as a thin
wrapper
over stdlib `errors`. A single `withStack` struct captures stack
traces via `runtime.Callers`; `fmt.Errorf("%w", ...)` handles all
message wrapping. Restores `errors.Is`/`As`/`Unwrap` chain traversal
(silently broken in the fork) and deletes ~190 lines of stack/frame
formatting. `Is`, `As`, `Unwrap`, and `Join` are re-exported so
callers need a single import.
- **`internal/logger`** — Swaps stdlib `log.Logger` for `log/slog` JSON
handlers with UTC timestamps and custom level labels (`verb`, `debug`,
`warn`, `error`). Hides `withContextID` (no external callers).
- **`internal/sync`** — Converts `Map[K, V]` from a concrete struct to
an interface with a `NewMap` constructor for testability.
- **`internal/signal`** — Adds `signalNotify` / `osExit` indirections so
`InstallSignals` and `InstallForceQuit` can be exercised without real
OS signals or process termination.
- **`internal/utils`** — Drops deprecated `io/ioutil` and the stdlib
`errors` alias (the internal `errors` package re-exports what's
needed).
- **`internal/version`** — No code changes; fully covered by new tests.
