From 339e5638b0a11ea3218214ffb57732098c3705df Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Thu, 17 Feb 2011 06:38:52 -0600 Subject: [PATCH] tests: skip terminal output tests on OS X On Mac OS X 10.5.0, test_terminal gets stuck reading from the pty master every once in a while. To reproduce the problem: perl -MIO::Pty -MFile::Copy -e ' for (my $i = 0;; $i++) { my $master = new IO::Pty; my $slave = $master->slave; if (fork == 0) { close $master or die "close: $!"; open STDOUT, ">&", $slave or die "dup2: $!"; close $slave or die "close: $!"; exec("echo", "hi", $i) or die "exec: $!"; } close $slave or die "close: $!"; copy($master, \*STDOUT) or die "copy: $!"; close $master or die "close: $!"; wait; } ' It blocks after 7000 iterations or so in sysread(). The relevant sysread() call is the second call by the parent, which presumably executes before the child dies but after the parent has read all output from there. Since this is an intermitent problem, the quick check of terminal support in lib-terminal doesn't catch it. Skip these tests on the Mac for now.
