TracingHook (Gerrit Review Plugin API Documentation)

java.lang.Object
- com.google.gerrit.server.git.TracingHook

All Implemented Interfaces:

AutoCloseable, org.eclipse.jgit.transport.ProtocolV2Hook
```
public class TracingHook
extends Object
implements org.eclipse.jgit.transport.ProtocolV2Hook, AutoCloseable
```
Git hook for ls-refs and fetch that enables Gerrit request tracing if the user sets the 'trace' server option.
This hook is only invoked if Git protocol v2 is used.
If the 'trace' server option is specified without value, this means without providing a trace ID, a trace ID is generated, but it's not returned to the client. Hence users are advised to always provide a trace ID.
