Bug #79553 for ExtUtils-MakeMaker: Cygwin: Prompt hangs

Mon Sep 10 12:07:47 2012 NHORNE [...] cpan.org - Ticket created

Subject:

Cygwin: Prompt hangs - does read anything

All input (except SIGINT) is ignored by prompt(). The prompt message is displayed, but you can't get past it except by hitting control-C which will abandon the build. It's happened to me on all versions of Cygwin and all versions of Perl that I've tried.

Thanks for your report.

Sorry, I cannot replicate this problem on Windows 7 (64 bit) with an up to date Cygwin using the built in Perl (5.14.2). I tried both the MakeMaker which comes with Cygwin (6.57_05) and MakeMaker 6.64. Would you please try MakeMaker 6.64? If that doesn't work, please give us some more information about your environment. Are you using a special shell or terminal?

Do you use CPAN::Reporter with command_timeout? Does same problem happen with modules that use Build.PL? -- Alexandr Ciornii, http://chorny.net

I haven't noticed one way or the other. -Nigel

Since we can't reproduce the problem, we're going to need some detailed information to figure out what's going on. I'm going to ask for what seems like a lot of information, it will make figuring out what's going on much faster if you can provide as much as possible. If attaching files is inconvenient, you can use a pasting site such as https://gist.github.com/ and give us the links. All the commands should be run in the Cygwin shell where you're having the prompt problems. What version of Windows are you using? For example, I'm using Windows 7 64bit. What version of Cygwin are you using? Please show us the output of "uname -a" and "cygcheck". Please attach the output of "perl -V" so we know details about your perl environment. What version of MakeMaker are you using? Running this command will tell you: perl -wle 'use ExtUtils::MakeMaker; print $ExtUtils::MakeMaker::VERSION' Would you please attach your copy of ExtUtils::MakeMaker. It can be found by running "perldoc -l ExtUtils::MakeMaker". Would you give us an example of a module or a sample program which causes prompt() to hang? Would you please show us the output of when you're installing a module and prompt() hangs? Does the problem happen if you run "perl Makefile.PL" directly? If it only happens in a CPAN shell, which shell? If its the CPAN shell, please attach ~/.cpan/CPAN/MyConfig.pm. Thank you for providing all this.

I think Cygwin was a red herring. I've noticed the same problem on other platforms.

E::M exhisbits this problem for me on several platforms in release 6.86. It's fine if I run Perl Makefile.PL; make from the command line, it only hangs when running install from a CPAN shell.

It seems that the problem goes away when inactivity_timeout in Cpan::Config is 0. Now that I come to think of it I am sure I've come across this problem before.

Please could you provide the output of: "ver" in a Command Prompt. "perl -V".

Thanks! Still waiting for the information on exactly which version of Windows you're running.

I didn't think you still needed given my comment on 23/1/14. I've seen it on both Vista and Windows 8.
