needsrestart perl warnings under perl 5.20

[glensc]

it prints too many notices here and there....

perl --version|head -n2

This is perl 5, version 20, subversion 1 (v5.20.1) built for x86_64-pld-linux-thread-multi

tried to see what options it supports:

Hi,

perl 5.20 should work - running needrestart on Debian jessie (perl 5.20.2) is not that noisy.

# needrestart -h

It seems to be triggered by a bug in Proc::ProcessTable. It was fixed some time ago: jwbargsten/perl-proc-processtable@c4d07f8

Argument "" isn't numeric in sort at /usr/sbin/needrestart line 276, <> line 1.

Which version of needrestart did you try (git HEAD / github release)? Btw: only longopts --help/--version is supported.

[..]

[Kernel/Linux] /boot/vmlinuz seems to be too small

The warning during kernel probing seems to be triggered by a dangling symlink (/boot/vmlinuz.old), isn't it?

[glensc]

for perl-proc-processtable@c4d07f8 maybe you bump your use Proc::ProcessTable X.Y to require newer fixed version?

i am using 2.0 release tarball from github

yes, both /boot/vmlinuz.old and /boot/vmlinuz are dead symlinks. is the prior warning from the same issue?

for short -h i just guessed, program will print usage or just "uknown option error" and abort :)

Thanks for giving 601ab27 a try. The warning in line 305 is related to jwbargsten/perl-proc-processtable@c4d07f8.

Using the use Proc::ProcessTable X.Y statement should only be used for features missing in older versions of a package IMHO - bug fixes might be backported.

Ignoring unknown argv parameters is required while using the debconf frontend on Debian GNU/Linux systems.

[glensc]

Do you know what is the version that is required for the Proc::ProcessTable bug to disappear? for the sake when somebody else gets this error and reaches this ticket.

[liske]

Seems to be fixed in Proc::ProcessTable 0.49+ (jwbargsten/perl-proc-processtable@1dc2ddc)
