What is the right way to create a detached thread and insure resources
are released upon termination under Libuv ?

Hi Folks:

Nobody commented on my question about spawning detached thread tasks.
Consequently, I looked at the code in src/unix/thread.c and discovered
pthread_create() does not have provisions for spawning a detached thread.

The routine in the attached file spawns a detached thread correctly on Unix/Linux
systems and works under fairly heavy testing. However, I am not sure it
is in line with the Libuv implementation conventions, and it is certainly
not elegant nor of optimal modularity.

I leave it up to the Libuv implementors to come up with a more complete
solution.

Best Regards,

Paul R.

Paul, your questions always come with code for people to review, and now you even ask for people to provide you with better or more complete code.

I'm afraid this is like asking for free consultancy and probably nobody here is gonna do that.

Please, make specific questions about libuv.

Hi Inaki:

My question was just about a kind of functionality which was not addressed by the Libuv
documentation, and upon investigation turned out to be missing. As I did not design or
write Libuv, I don't consider it my responsiblity to implement missing features. But perhaps,
there is a valid reason why detached threads are not implemented in Libuv.

The code attached to my previous message is just a courtesy to the Libuv implementors.

Best Regards,

Paul R.

I don't know what to say about that, really.

This is not how things work. People, even those who did not "design or
write libuv" create Pull Requests with bug fixes or new features.

The functionality is already present in libuv master as `uv_thread_detach`

I started my experiments with Libuv using the version in libuv-1.40.0.tar .gz which, I think,
is quite a bit behind the latest version. That is the reason I didn't find uv_thread_detach()
which has detached thread functionality.

Hi Folks:

1.41 appears to be the latest version and doesn''t seem to have uv_thread_detach(). Comments on the Internet suggest it
is in the master version. How do I donwload the latest stable version of the master ?

Best Regards,

Paul R.

Those are basic GIT questions. This is not a forum about that.

OK, I determined that v1.41 is the latest version with the git tools and it doesn't have uv_thread_detach(). So I'm confused about
which version has uv_thread_detach(). Am I missing something ?
