EyeDisposable

What?

If you have used IDisposable, you will know the problem. It's very easy to "leak" them by forgetting to call Dispose() on them. Yes, most objects' finalizers will eventually call Dispose(), but it's a bad practice to rely on finalizer being run at all. It's cleaner and neater to Dispose() of them at an appropriate time.

Usage

1. Instrument your entry assembly and other dependent assemblies.

> EyeDisposable.exe C:\Projects\Foo\Foo.exe

Instrumenting type `<Module>`...
Instrumenting type `Foo`...
Instrumenting type `Program`...
- System.Void Foo.Program::Main(System.String[]): 1 newobjs; 0 disposes
Instrumenting entry point...

> EyeDisposable.exe C:\Projects\Foo\Bar.dll
...

2. Run

> cd C:\Projects\Foo
> Foo.exe

3. Profit

> type Foo.exe.DisposeLeaks.log
====
Disposer check
1 leaks detected!
====
Disposable object leaked!
Hash code: 30015890
Type: Foo.Foo
Created at:
> [Foo.Program] Void Main(System.String[])
> [Foo.Program] Void EyeDisposable_NewMain(System.String[])

How does it work?

EyeDisposable uses Mono.Cecil to instrument assemblies. newobj and Dispose() calls are tallied and checked at the end of the program.

Cloning

You need to update the Cecil submodule after cloning:

> git clone git://github.com/kizzx2/EyeDisposable.git
> cd EyeDisposable
> git submodule update

Limitations

• IDisposable value types are not supported.
