Description Ross Burton 2019-10-21 16:49:54 UTC 
The reproducible QA test fails for the following packages:

perl-dbg_5.30.0-r0_amd64.deb
perl-module-config-heavy_5.30.0-r0_amd64.deb
perl-module-digest-md5_5.30.0-r0_amd64.deb
perl-module-encode-byte_5.30.0-r0_amd64.deb
perl-module-encode-cn_5.30.0-r0_amd64.deb
perl-module-encode-ebcdic_5.30.0-r0_amd64.deb
perl-module-encode-jp_5.30.0-r0_amd64.deb
perl-module-encode-kr_5.30.0-r0_amd64.deb
perl-module-encode-symbol_5.30.0-r0_amd64.deb
perl-module-encode-tw_5.30.0-r0_amd64.deb
perl-module-encode_5.30.0-r0_amd64.deb
perl-module-tie-hash-namedcapture_5.30.0-r0_amd64.deb
perl-ptest_5.30.0-r0_amd64.deb
perl-src_5.30.0-r0_amd64.deb

Looks like this might be Fedora-as-host specific.
Comment 1 Ross Burton 2019-11-14 15:48:08 UTC 
So one reason is that pod2man embeds the version in generated documentation, and if the pod2man version in two otherwise identical builds is different then the manpages change.

https://github.com/rossburton/meta-ross/blob/master/classes/insanitier.bbclass#L115 is a QA test to warn if manpages contain pod2man versions.

poky-contrib:ross/pod is a WIP branch that:
1) patches out the version number from perl-native, so builds using pod2man or the Pod module directly from perl-native don't embed the version
2) had a pod2man wrapper in HOSTTOOLS which removes the version from manpages written using host pod2man.  This should potentially be rewritten to use scripts/native-intercepts, which I forgot existed

However this doesn't remove all versions.  I suspect the remaining versions come from builds that are using the host perl and the Pod module directly instead of pod2man.  I'm not sure how to solve this.

Looks like we fixed this with e3d5f55c3e07eb6f99f25f25885a45c495b6647a which removes the reproducible problems in pod2man.
