=== Memory Caching

The Daemon enables in-memory caching across builds.
This includes classes for plugins and build scripts.

Similarly, the Daemon maintains in-memory caches of build data, such as the hashes of task inputs and outputs for incremental builds.

== Performance Monitoring

Gradle actively monitors heap usage to detect memory leaks in the Daemon.

When a memory leak exhausts available heap space, the Daemon:

	var hash map[string]*LSym
	switch abi {
	case ABI0:
		hash = ctxt.hash
	case ABIInternal:
		hash = ctxt.funchash
	default:
		panic("unknown ABI")
	}

	ctxt.hashmu.Lock()
	s := hash[name]
	if s == nil {
		s = &LSym{Name: name}
		s.SetABI(abi)
		hash[name] = s
		if init != nil {
			init(s)
		}
	}
	ctxt.hashmu.Unlock()
	return s
}

	Pathname           string
	Pkgpath            string           // the current package's import path
	hashmu             sync.Mutex       // protects hash, funchash
	hash               map[string]*LSym // name -> sym mapping
	funchash           map[string]*LSym // name -> sym mapping for ABIInternal syms

    }
