Re: Is Net::SSH::Expect a thread-safe module?

in reply to Is Net::SSH::Expect a thread-safe module?

I didn't find this information in the module description even.

This probably means it is not thread-safe

However, Net::SSH::Expect is pure-perl, this probably means it is thread-safe, it depends on the dependencies

Expect is a dependency, so the question, is Expect thread-safe

http://search.cpan.org/dist/Expect/Expect.pod#Is_it_possible_to_use_threads_with_Expect?

Basically yes, with one restriction: you must spawn() your programs in the main thread and then pass the Expect objects to the handling threads.

So yeah, Net::SSH::Expect is probably thread safe

That is a miserable thing to do to a beginner Anon.

You might have finished the quote from the Expect POD which goes on to say:

The reason is that spawn() uses fork(), and perlthrtut:

"Thinking of mixing fork() and threads? Please lie down and wait until the feeling passes."

which whilst having more in common with the old map notations, "there be dragon's here", than rational or tested advice, probably does mean that if you venture beyond that point, you will likely be on your own and are going to be breaking new ground.

Throwing "So yeah" at a (threads) beginner is just mean.

You mean a threads beginner like me?

I can't test it either, which is why I did not speak like I knew for sure.

The way I read the docs, it probably will work -- its not like it would take long to determine one way or another.

Actually, he has been trying to determine that for a while now and hasn't really reached a conclusion. Hence this latest thread.
