graceful

Overview ¶

graceful demonstrates signal-driven single-app graceful shutdown.

This is the drain-oriented shutdown path for one gogo App:

• SIGINT / SIGTERM stops accepting new connections
• accepted requests are allowed to finish naturally
• the context deadline force-closes active connections if they hang
• resources are closed after Run returns

Run with:

CGO_ENABLED=1 go run -tags gogo ./examples/graceful
curl http://127.0.0.1:3006/health
curl http://127.0.0.1:3006/slow

While /slow is running, press Ctrl+C in the server terminal. The request should finish before the process exits. RunMultiCore has a different group-level shutdown model: MultiCoreHandle.Shutdown calls each worker's immediate Shutdown and does not currently expose this graceful drain.
