From eldon.olmstead@newpace.com

This is a bug report for perl from eldon.olmstead@​newpace.com,
generated with the help of perlbug 1.39 running under perl 5.16.3.

The following command hangs on the call to getpwuid. This is a similar
invocation found in the perl build directory under t/op/pwent.t

perl -e 'eval {my @​n = getpwuid 0;}; if ($@​) { print $@​ }'

The unit test t/op/pwent.t also hangs during testing of getpwuid and setpwent().

However, i have confirmed that calling setpwent doesn't hang.

You are configuring with a long list of options. Although I cannot see
any one of those which might cause this failure, it might be worthwhile
to try reconfiguring, building perl and running 'make test' again to see
if the error re-appears. For example, what if you just tried​:

sh ./Configure -des -Dprefix=/home/bizapp/perl5/perlbrew/perls/perl-5.16.3

The unit test t/op/pwent.t also hangs during testing of getpwuid and
setpwent().

Would you be able to attach the output of the following to this ticket?

In the directory where you were building and testing this instance of
perl, say​:

cd t;./perl harness -v op/pwent.t; cd-

However, i have confirmed that calling setpwent doesn't hang.

The unit test t/op/pwent.t also hangs during testing of getpwuid and setpwent().

Was does running that command under strace show it hanging on?

What setup do you have for the user database? local files, or NIS or LDAP
or ....?

What are the entries for passwd and shadow in /etc/nsswitch.conf ?

My Dad used to say 'always fight fire with fire', which is probably why
he got thrown out of the fire brigade.

From eldon.olmstead@newpace.com

This is in reply to both James and Dave.

I tried as James suggested and rebuilt perl ( 5.16.2 this time, see perl-5.16.2.txt attached) with only defaults. The problem still exists and I have found the simplest method to reproduce the problem is to invoke perl as follows​:

  perl -e '@​n=getpwuid 0;'

To answer Dave's questions​:

We are using LDAP.

cat /etc/nsswitch.conf
# Modified /etc/nsswitch.conf file for LDAP
passwd​: compat
passwd_compat​: ldap
shadow​: files ldap
group​: files ldap
hosts​: files dns
bootparams​: files
ethers​: files
netmasks​: files
networks​: files
protocols​: files
rpc​: files
services​: files
netgroup​: ldap
publickey​: nisplus
automount​: files
aliases​: files

Running the following also only hangs​:
$ ./perl harness -v op/pwent.t
op/pwent.t ..

Using the debugger on the above I get the following​:

$ perl -d op/pwent.t

Loading DB routines from perl5db.pl version 1.37
Editor support available.

Enter h or 'h h' for help, or 'man perldebug' for more help.

main​::(op/pwent.t​:12)​: eval {my @​n = getpwuid 0; setpwent()};
  DB<1> n
main​::(op/pwent.t​:12)​: eval {my @​n = getpwuid 0; setpwent()};
  DB<1> n <Hangs here>

So next I tried strace with the above and get the following output. ( see attached perl-5.16.2-strace.txt )

I've also noted that the system perl (5.8.8 see perl-5.8.8.txt for configuration) is having the same issue so your questions are leading me to believe there is a system configuration problem.

t $ which perl
/usr/bin/perl

t $ perl -v

t $ perl -e '@​a=getpwuid 0;' <hangs again>

However, I do have root access and the above doesn't hang ( see perl-5.8.8-strace-as-root.txt ).

Unfortunately that doesn't help much, because that's just tracing the perl
process running the harness, not the child perl process running
op/pwent.t

Could you run strace on your 5.16.2 perl, just running the command shown
above, e.g.

$ strace -o /tmp/perl-5.16.2-strace.txt -tt perl-5.16.2 -e '@​n=getpwuid 0;'

I've also noted that the system perl (5.8.8 see perl-5.8.8.txt for
configuration) is having the same issue so your questions are leading me
to believe there is a system configuration problem.
[snip]
However, I do have root access and the above doesn't hang ( see perl-5.8.8-strace-as-root.txt ).

Again, seeing an strace of the non-root hanging 5.8.8 would be handy

We haven't heard back in over 8 years from the OP re @iabyn's request for more information. Closing this ticket.
