Subject: [ruby-core:48563] [ruby-trunk - Feature #5958][Rejected] ThreadGroup#join


Issue #5958 has been updated by ko1 (Koichi Sasada).

Status changed from Assigned to Rejected

Now, I reject this ticket.

I think your proposal is very useful.
To introduce thread set manipulation is needed.

But I feel it is not mature.
Please re-design ThreadGroup and make another tickets.

Feature #5958: ThreadGroup#join

=begin
I propose the method ThreadGroup#join.
Calling thread waits all threads in receiving threadgroup.

 thgrp = ThreadGroup.new
 thgrp.add(Thread.new{ sleep 1 })
 thgrp.join #=> #<ThreadGroup:0x007ff257d6d098>

Time limit to run the threads in the threadgroup can be specified.
If the time limit expires, nil will be returned.

 thgrp = ThreadGroup.new
 thgrp.add(Thread.new{})
 thgrp.add(Thread.new{ sleep })
 thgrp.join(0.1) #=> nil

I think it is useful to wait grouped threads together.
