Canceling in rails console

[martnst]

Hi,

apparently interrupt signal in threads is not supported anymore. Hence I am wondering why that is the case and furthermore if there is any alternative to cancel long running stuff while being in the rails console.

Thx

Should be supported, if not that's a bug, please try to reproduce / fix
(maybe simplest with bundle open parallel)

1. here it says it's not supported anymore https://github.com/grosser/parallel/blob/master/lib/parallel.rb#L299
2. Trying this with in_threads: 3 does not cancel when hitting CTRL + C

[22] pry(main)> Parallel.map(1..50, in_threads: 3, progress: "Doing stuff") { sleep 1 }
^CInterrupt:  ETA: 00:00:19 | ================                                                                                                          | Time: 00:00:03

[24] pry(main)>

ah yes ... the whole interrupt handling is supported via an at_exit hook
and that is not getting set up when using threads :/

I'd prefer not to mess with at_exit ... maybe there is some other way the
Interrupt can get caught by the threads ... not even sure if the at_exit
would trigger since this is in irb ...
