Subject: Ctrl-C/Ctrl-D in the CPAN shell causes an endless loop only when Term::ReadLine::Perl is installed
The following report was from perlbug originally. It does not appear to be a problem with CPAN, since the problem does not occur with Term::ReadLine::Gnu. It is repeatable with CPAN and Term::ReadLine::Perl. The following components were used: CPAN 0.70 Term::ReadLine::Perl 1.0203 In the following tests start the CPAN shell and then press Ctrl-C, followed by Ctrl-D == 5.8.0: % perl-5.8.0 -MCPAN -eshell Show quoted text

I can't reproduce it here with 5.8.2 + TRP. I do not get "Caught SIGINT". Hope it helps, Ilya

I can reproduce this easily. I get the 'Caught SIGINT' when pressing ^C, and the infinite loop of uninit warnings comes when I press ^D. This is on a SuSE9.3 system: $ env "PERL_RL=Perl" cpan cpan shell -- CPAN exploration and modules installation (v1.7601) ReadLine support enabled Show quoted text

11 but I also can reproduce the problem with multiple versions of Perl, CPAN, and T::RL::Perl. I was able to stop it from happening, however, with the following patch against version 1.0203. --- Term/ReadLine/readline.pm.old Tue Mar 14 07:21:48 2006 +++ Term/ReadLine/readline.pm Tue Mar 14 07:21:38 2006 @@ -1478,6 +1478,7 @@ $ThisCommandKilledText = 0; ##print "\n\rline is @$D:[$line]\n\r"; ##DEBUG + last if ! defined $input; &do_command($var_EditingMode, 1, ord($input)); ## actually execute input *KeyMap = $var_EditingMode; # JP: added

Looks like your TTY device driver and/or Term::ReadKey are borken. Show quoted text

The current version is 1.0208. Hope this helps, Ilya
