ISO changelog extracter creates empty files

[DimStar77]

The changelog extractor, which is used to produce the announcement mails to openSUSE-Factory,produces empty files, i.e.

This is potentially a fallout from the upgrade of ariel to Leap 15.1:

2019-07-09 19:31:10|command|root@ariel|'zypper' '-n' '--releasever=15.1' 'dup' '--auto-agree-with-licenses' '--replacefiles' '--download-in-advance'|
2019-07-09 19:31:11|remove |ruby2.1-rubygem-json_pure|1.8.2-6.3|x86_64||

from_733: broken byte order is a message from libcdio

the warning have been there since about forever. I don't think they are your problem.

http://git.savannah.gnu.org/cgit/libcdio.git/commit/?id=8be41a36b8792b7d99fc8383a6c426d8b63ec6a8 - new in libcdio 0.94 - which came with Leap 15.0 - 42.3 was at libcdio 0.93

[DimStar77]

I backported two patches from libcdio 2.1 to the Leap 15.1 provided libcdio 0.94.
The patched version of libcdio is currently installed on ariel - and the changelog extractor is functional again (diff of 0713->0716 https://openqa.opensuse.org/factory-package-news/diff/20190716)

In parallel, I submitted my fixed version of libcdio into the SLE15 maintenance process

As such, I think we can safely close this issue: nothing needed be done in the releng tooling, the bug was introduced by upgrading to Leap 15.1 (well, not really - the bug is ultimately in the product builder)
