Summary

0003666: Bug in the Unix.sleep when used after Graphics.synchronize

Description

Full_Name: Damien Bobillot

OS: Linux (Redhat & Gentoo)
Submission from: 132.227.81.31 (132.227.81.31)

==== test.ml ====
Graphics.open_graph "";
Graphics.synchronize ();
Printf.printf "cou%!";
Unix.sleep 60;
Printf.printf "cou\n%!";
=============

> ocamlopt.opt -c test unix.cmxa graphics.cmxa test.ml

When running ./test, the program dont wait 1 minute between printf "cou" calls.

This bug doesn't appear in the Mac OS X version.

I've tried to block all signals (with Unix.sigprocmask Unix.SIG_SETMASK
[-1;-2;...;-20;-21]), but it doesn't solve anything.

Notes
(0000261) administrator (administrator) 2005-07-20 10:37	It's not a bug, it's a SIGIO signal that interrupts Unix.sleep (under Unix -- MacOS X restarts the syscall). Feature wish: a Graphics library that does not use signals (but e.g. threads).
