owner, status, version changed

owner changed from Anthony Williams to viboes
status new → assigned
version Boost 1.52.0 → Boost 1.53.0

I agree, and I had already on my to do list. However, much more work is needed to move it to Boost:

make the BOOST_THREAD_LOCAL part portable to compilers that doesn't have the needed feature.
add timed lock functions
provide tests
write the doc: a motivating section, a brief tutorial, an example and the reference

if you can help on any of these task there are more chances the feature is included.

BTW, alternatively you can provide this hierarchical mutex class as a separated library if you prefer.

Hi Frederick,

what kind of license is you code? Am I allowed to use it as i like? Is it the same as thread's (http://www.boost.org/LICENSE_1_0.txt)

Cheers!

Yes, feel free to use my code with the Boost license. :-)

Do you mind to provide some documentation and tests and update your code with the Boost license?

I've now uploaded a 7-zip archive with an updated hierarchical_mutex implementation. All files are tagged with Boost license information. The archive also contains a tiny test suite, as well as a semi-portable "thread_local" emulation.

Feel free to do what ever you want with the implementation. I hope that Boost could consider adopting this pattern in one way or another, since it makes debugging and avoiding deadlocks much easier.
