Need IO::Pty help with *BSD/OSX
Recently I encountered an issue with Expect.pm on OSX. I think it is caused by a bug in IO::Pty (Expect.pm is a subclass of IO::Pty) and thus filed a bug report there. I even created a test-case and released an unofficial version of Expect.pm with a test exposing the problem.
Today, thanks to the countless CPAN smokers of BinGOs (aka Chris Williams) I got the first test reports that indicate the same problem exists on OpenBSD and NetBSD as well. (Surprisingly, there are no reports at all on FreeBSD and OSX!)
As I don't have any knowledge of BSDs and this IO::Pty stuff, I wonder if there is anyone out there with such expertise? Could you look into this issue?
I blog about Perl.
For at least OpenBSD and NetBSD, there are patches in ports/pkgsrc for IO-Pty/Expect which may be related.
Thanks. As I am not familiar with either of those systems, could you please link to these patches? Or at least confirm that you mean what I found so far:
pkgsrc.se seems to be the home of NetBSD packages. It has a search functionality that helped me locate the page for Expect.pm and another one for IO-Tty.
In there I could not find any code changes for Expect.pm (all the changes seem to be to the NetBSD Makefile).
For IO-Tty I found this entry that seems to indicate there is a patch called: pkgsrc/devel/p5-IO-Tty/patches/patch-Tty.xs
The patch adds util.h to the include list if.
http://cvsweb.netbsd.org/bsdweb.cgi/~checkout~/pkgsrc/devel/p5-IO-Tty/patches/patch-Tty.xs?rev=1.1&content-type=text/plain
Bingos has an open pull request here on the IO::Tty repo:
https://github.com/toddr/IO-Tty/pull/3/commits
It seems however the patch is unrelated to your problem?
Gabor, your test fails on FreeBSD as well. The bc(1) in *BSD is different from the GNU bc in Linux and does not print anything at startup, hence no qr/warranty'\./ line. Also, I get back 23 from the test instead fo 30:
spawn id(5): beginning expect.
Timeout: 1 seconds.
Current time: Sun Aug 3 06:58:41 2014
Waiting for new data (1 seconds)...
spawn id(5): new data.
spawn id(5): read 6 byte(s).
23+7
Returning from expect successfully.
spawn id(5): accumulator: `+7\r\n'
not ok 1
# Failed test at 02-bc.t line 28.
# got: '23'
# expected: '30'
Closing spawn id(5).
