test suite drops a daemon running forever

From time to time I find a running process pair like this: k 18692 0.0 0.0 2956 1328 pts/4 S+ Jan01 0:00 sh -c /home/src/perl/repoperls/installed-perls/perl/prOxRQY/perl-5.8.0@29651/bin/perl -Iblib/lib -Iblib/arch -I/home/src/perl/repoperls/installed-perls/perl/prOxRQY/perl-5.8.0@29651/lib/5.9.5/i686-linux-64int -I/home/src/perl/repoperls/installed-perls/perl/prOxRQY/perl-5.8.0@29651/lib/5.9.5 -I/home/src/perl/repoperls/installed-perls/perl/prOxRQY/perl-5.8.0@29651/lib/site_perl/5.9.5/i686-linux-64int -I/home/src/perl/repoperls/installed-perls/perl/prOxRQY/perl-5.8.0@29651/lib/site_perl/5.9.5 -I. examples/sslecho.pl 1212 examples/cert.pem examples/key.pem Show quoted text

Confirmed on perl 5.8.8 Linux 2.6 x86_64. It seems to be the server raised at line 97 of test.pl. It is not killed by the "kill $pid" at line 134. I cannot identify this issue further. Maybe you can check if kill successed. You may refer to the attached console log. Also, this seems to cause CPANPLUS hang, waiting for its child to die forever, if the user is running from CPANPLUS. Because several modules rely on Net_SSLeay.pm, they cannot be tested by CPAN testers for this dependency. Please tell me if I could be of any help, or if you need any more information.

Dear Florian Ragwitz, Hi. This is imacat from Taiwan. I have made more tests. It seems that this keep-running daemon is this "SSL test server on port 1212" in test.pl line 98, and is the cause that CPANPLUS hangs waiting for. Once I kill it CPANPLUS returns. Further investigation reveals that: "kill $pid" is not working at test.pl line 134. According to the perlfunc(1) documentation http://perldoc.perl.org/functions/kill.html It show that "kill 15, $pid" should be used instead of "kill $pid". You omitted the kill signal and Perl treats $pid as the signal with an empty process ID list. I have make some tests. After changing "kill $pid" to "kill 15, $pid" that daemon is killed, and CPANPLUS returns as usual when tests finish. There seem to be still another daemon running, with a PID next to that one. I don't quite understand yet. I attached a simple patch that may solve this issue, in the hope that it helps. Please tell me if I could be of any help, or if you need any more information. Thank you. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 diff -u -r Net_SSLeay.pm-1.30.orig/test.pl Net_SSLeay.pm-1.30/test.pl - --- Net_SSLeay.pm-1.30.orig/test.pl 2005-12-01 10:20:34.000000000 +0800 +++ Net_SSLeay.pm-1.30/test.pl 2007-03-28 03:57:05.000000000 +0800 @@ -131,7 +131,7 @@ print "\t\t...took $secs secs (" . int($mb*1024/$secs).

because I find downloading of patches from RT.cpan.org more than inconvenient I uploaded this patch to CPAN as ANDK/patches/Net_SSLeay.pm-1.30-IMACAT-01.patch.gz Thanks, imacat, your patch works like a charm. andreas
