Detect all kinds of leaks in Go

go-leak GoDoc

The std packages of Go do currently not included detection for leaks. go-leak is a package which should help you find leaks in your code. If you have any ideas on how to improve this package or have problems of any kind with it, please submit an issue through the issue tracker.

Note: This package does not work anymore. It worked for some use-cases I had with an older Go version but with >= 1.4 it does not work at all. I have it on my TODO to redo the whole thing and add some more use-cases but there are some other open source projects I have to do first. So if you have some time on your hand and would like to contribute mail me or submit an issue in the project's tracker.

Note: Since Go is scoped it is important to avoid new variables that are in the same scope as the mark-and-release calls.

goroutines

If you want to know if a function is leaking goroutines:

leaks := leak.GoRoutineLeaks(foo)

if leaks > 0 {
	panic("foo is leaking!")
}

If you want to know if a code is leaking goroutines:

m := MarkGoRoutines()

// some code

leaks := m.Release()

if leaks > 0 {
	panic("some code is leaking!")
}

memory

If you want to know if a function is leaking memory:

leaks := leak.MemoryLeaks(foo)

if leaks > 0 {
	panic("foo is leaking!")
}

If you want to know if a code is leaking memory:

m := MarkMemory()

// some code

leaks := m.Release()

if leaks > 0 {
	panic("some code is leaking!")
}
