1483562 – numify() method does not work correctly

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jakub Heger 2017-08-21 12:16:00 UTC

Description of problem:
According to documentation [1], numify() method should remove trailing zeroes. 
However if I try the command from example, trailing zeroes are there.

[1] http://search.cpan.org/~jpeacock/version-0.9918/lib/version.pod

Version-Release number of selected component (if applicable):
perl-5.16.3-292.el7.x86_64
perl-version-0.99.07-3.el7.x86_64
version module both:
    -0.9907
    -0.9918

How reproducible:
Always

Steps to Reproduce:
1. perl -e 'print version->declare('v1.2')->numify;'
2.
3.

Actual results:
1.002000

Expected results:
1.002

Additional info:

Comment 1 Petr Pisar 2017-08-21 12:58:15 UTC

The RHEL-7's documentation, as of perl-version-0.99.07-2.el7.x86_64, is:

  numify()
    Returns a value representing the object in a pure decimal form without
    trailing zeroes.

     version->declare('v1.2')->numify;  # 1.002
     version->parse('1.2')->numify;     # 1.2

That was discussed in <https://rt.cpan.org/Public/Bug/Display.html?id=64635> with the resolution that the documentation is wrong:

  The documentation is in error. The "numify" operator has returned trailing
  zeros (in multiples of 3) since March 2006 and the POD never got updated.

The latest upstream, 0.9918, has different documentation:

  numify()
    Returns a value representing the object in a pure decimal form without
    trailing zeroes.

     version->declare('v1.2')->numify;  # 1.002
     version->parse('1.2')->numify;     # 1.200

It fixed the second example, but it still wrongly states "without trailing zeroes".


Now to the behavior:

RHEL-7 pacakges perl-version-0.99.07-2.el7.x86_64 and perl-version-0.99.07-3.el7.x86_64 as well as latest upstream 0.9918 behaves like this:

$ perl -Mversion -e 'print version->parse('v1.2')->numify, qq{$a\n}'
1.002000

I agree this was an unintended changed and I will work with upstream to correct it.

Comment 3 Petr Pisar 2018-03-06 15:31:41 UTC

Because the software works as intended by upstream, we are going to correct the documentation.

Comment 4 Petr Pisar 2018-03-09 14:09:48 UTC

Created attachment 1406262 [details]
Proposed fix

This changes documentation to much current behavior.
