Re: [Expectperl-discuss] spawn hanging on darwin

[<RGi...@a1...>]

I did some further investigations and have come to the conclusion that =

Darwin has a severe bug=3A

 When a spawned program exits=2C the master immediately gets EOF and all =

characters that should have been queued inside the pty are lost=2E

 When the spawned program closes the pty before exiting=2C no characters =

are lost=2E

This leads me to the conclusion that the close-on-exit is broken on =

Darwin=2E

Workaround=3A add a =27sleep 1=27 to the spawn command=2C i=2Ee=2E spawn(=
=22someprog=3B =

sleep 1=22)=2E

I don=27t know if this helps with Crypt=3A=3APGP=2C but it=27s a first st=
ep=2E
