The program 'pod/buildtoc' is nearly the last step run by 'make'. It
generates 'pod/perltoc.pod' from all the other .pod files in the core
distribution. If, however, you run the 'podchecker' utility over
'pod/perltoc.pod', you will get both WARNINGs and ERRORs. For example,
in perl-5.26.0, you get​:

Yup. This was caused by my release. I'm working on it and will push

Well, not entirely your fault. The errors processing TAP​::Harness can be found in perl-5.24.1. See below.

I've finished all the steps for fixing the perltoc and preparing blead
for 5.29.0 and I'm not getting anymore errors and warnings.

Could you please confirm it is resolved, Jim?

Well, not entirely your fault. The errors processing TAP​::Harness can be found in perl-5.24.1. See below.

The program 'pod/buildtoc' is nearly the last step run by 'make'. It
generates 'pod/perltoc.pod' from all the other .pod files in the core

'pod/perltoc.pod', you will get both WARNINGs and ERRORs. For

When I run pod/perlunicode.pod and cpan/Test-
Harness/lib/TAP/Harness.pm
through the standard 'podchecker' utility, both are graded 'pod
syntax
OK'. So something is probably amiss with the pod/buildtoc program.

Thank you very much.

But I don't think that's due to anything you have or have not done. I think it's probably a long-standing implementation defect in pod/buildtoc. So this is not an impediment to perl-5.29.0.

Were you getting errors different from these?

Is this still a problem?

The last two POD-formatting errors reported by running podchecker over pod/perltoc.pod in blead are:

*** ERROR: unresolved internal link 'runtests' at line 34985 in file pod/perltoc.pod
*** ERROR: unresolved internal link 'summary' at line 34985 in file pod/perltoc.pod
pod/perltoc.pod has 2 pod syntax errors.

These can be averted by using C<> rather than L</>. I have filed this patch upstream:
https://rt.cpan.org/Ticket/Display.html?id=143622

(However, given that on CPAN the TAP-Harness distribution is in ADOPTME status, I'm not optimistic about there being a new CPAN release any time soon.)

In blead (v5.37.1-51-g6e37db9b2e), we are now getting 7 instances of this kind of warning when running podchecker pod/perltoc.pod:

*** WARNING: empty section in previous paragraph at line 18738 in file pod/perltoc.pod
*** WARNING: empty section in previous paragraph at line 23147 in file pod/perltoc.pod
*** WARNING: empty section in previous paragraph at line 23165 in file pod/perltoc.pod
*** WARNING: empty section in previous paragraph at line 23167 in file pod/perltoc.pod
*** WARNING: empty section in previous paragraph at line 23309 in file pod/perltoc.pod
*** WARNING: empty section in previous paragraph at line 23311 in file pod/perltoc.pod
*** WARNING: empty section in previous paragraph at line 23327 in file pod/perltoc.pod

All but the first are situations where we have two =head2 statements with only a blank line between the first and second. Example:

23145 =head2 Encode::CJKConstants -- Internally used by Encode::??::ISO_2022_*
23146 
23147 =head2 Encode::CN - China-based Chinese Encodings
23148 

Examining cpan/Encode/lib/Encode/CJKConstants.pm, we see that this is the only POD in the file and occurs at the end of the file.

 61 =head1 NAME
 62 
 63 Encode::CJKConstants.pm -- Internally used by Encode::??::ISO_2022_*
 64 
 65 =cut
 66

Addressed by @khwilliamson in e91f88a.

All but the first are situations where we have two `=head2` statements with only a blank line between the first and second. Example:

23145 =head2 Encode::CJKConstants -- Internally used by Encode::??::ISO_2022_*
23146
23147 =head2 Encode::CN - China-based Chinese Encodings
23148

Since this is not unreasonable coding, I think we can live with these 6 flaws.

Examining cpan/Encode/lib/Encode/CJKConstants.pm, we see that this is the only POD in the file and occurs at the end of the file.

 61 =head1 NAME
 62 
 63 Encode::CJKConstants.pm -- Internally used by Encode::??::ISO_2022_*
 64 
 65 =cut
 66 

And, as noted in #16595 (comment), a patch has been submitted upstream for the two ERRORs reported.

So there's nothing more that P5P can practically do here. Closing ticket.
