Free .Net Deadlock Debugging Tool

Corneliu, creator of the GUI debugging tool HawkEye, has a debugging tool that works against most .NET programs, without recompiling them. The follwoing are its features:

1. The tool does not require to have the code re-compiled in any way or form, with any external dependencies, nor reference any external library or have you modify your code to use any special type of locks inside your code.
2. It works on release builds with no PDB files.
3. It works on running processes or previously captured memory dumps.
4. It detects deadlocks across multiple threads and returns detailed call-stack and lock usage information.
5. It only detect deadlocks in which threads are actively waiting for locks acquired by other threads.
6. It does not detect the dining philosophers problem or deadlocks created in combination of time waits + wake/check + lock.
7. It has an external dependency on the cdb.exe (part of the the free Debugging Tools for Windows package from Microsoft).
8. It requires absolutely no installation. It an xcopy deployment.
9. And best of all it’s free (source code to be published soon)

The tool is discussed @ http://www.acorns.com.au/blog/?p=129 and may be obtained @ http://www.acorns.com.au/files/ACorns.Debugging.DeadlockTests.1.0.1.zip

Google, XML, and IDL

Google has stated that XML is not efficient enough to encode all data formats. To wit, it has resurrected the Interface Definition Language and binary format for data inter-change.

Googel-made code is available @ http://tinyurl.com/5d4bs5.

The product is called Protocol Buffers and is released under the Apache 2.0 open-source license.

Developers can define data structures using the definition language, producing .proto class files. Current language support is limited to C++. See Kenton Varda @ https://tinyurl.com/5hlyd9
