Hi,
I am installing Net::Daemon (v0.48) from source. I am on activestate Perl v 5.16.3 (Win 7 64 bit). make test return failure and cause perl interpreter to stop working in t/threadm.t test. I debugged test and found this.
c:\Perl64\cpan\build\Net-Daemon-0.48-ISrOkZ>perl "-MExtUtils::Command:
+:MM" "-e" "test_harness(1, 'blib\lib', 'blib\arch')" t/ithreadm.t
t/ithreadm.t ..
Starting server: C:\Perl64\bin\perl.exe -Iblib/lib -Iblib/arch t/serve
+r --mode=ithreads logfile=stderr debug
Starting process: proc = C:\Perl64\bin\perl.exe, args = C:\Perl64\bin\

+r
r debug

ok 1
Dubious, test returned 116 (wstat 29696, 0x7400)
Failed 9/10 subtests

Result: FAIL
Failed 1/1 test programs. 0/1 subtests failed.
I have checked the test code and it is failing on
$tid->join(). That time I can see mutiple instance of perl process in the system.
my @threads;
for (my $i = 0; $i < 10; $i++) {
#print "Spawning child $i.\n";
my $tid = threads->new(\&MyChild, $i);
if (!$tid) {
print STDERR "Failed to create new thread: $!\n";
exit 1;
}
push(@threads, $tid);
}
eval { alarm 1; alarm 0 };
alarm 120 unless $@;
for (my $i = 1; $i <= 10; $i++) {
my $tid = shift @threads;
#culprit==== if ($tid->join()) {
print "ok $i\n";
} else {
print "not ok $i\n";
}
}
I have checked cpan-rt and found similiar bug
https://rt.cpan.org/Public/Bug/Display.html?id=75005, but the workaround didn't solve my problem.
When I modify condition
if (1) {
print "ok $i\n";
} else {
test went pass. I am not much familiar with threads, so why this is causing the problem.
Is this a test problem? should I report a bug on cpan RT ?
Thanks,
updated title ,typo in name.
