Herve Boutemy commented on NIFI-10892:
--------------------------------------
updating data as of NiFi 2.0.0:
https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/content/org/apache/nifi/nifi/README.md
I re-analyzed remaining issues diffoscope:
https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/content/org/apache/nifi/nifi/nifi-2.0.0.diffoscope
I see 2 causes for a majority of issues, that seem fixable:
- JAXB output
- Git branch name in output
if anybody from the project know how to easily solve them, this could be easy
improvements for next release
if my help is needed, don't hesitate to tell
> continue Reproducible Builds improvements

> Key: NIFI-10892
> URL: https://issues.apache.org/jira/browse/NIFI-10892
> Project: Apache NiFi
> Issue Type: Improvement
> Affects Versions: 1.19.0
> Reporter: Herve Boutemy
> Priority: Major
>
> NIFI-10616 was merged, fixing one source of non-reproducible bits
> https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/content/org/apache/nifi/nifi/README.md
> there are still other issues to solve: on 1877 output files, 1677 are
> reproducible but 200 remain non-reproducible
> result summary is
> https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/content/org/apache/nifi/nifi/nifi-1.19.0.buildcompare
> detailed result diff is:
> https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/content/org/apache/nifi/nifi/nifi-1.19.0.diffoscope
> Analyzing remaining issues:
> - NIFI-10325 is required by 165 .nar files: fixed in 1.20.0
> - quite a few .jar files have reproducible issues with JAXB-generated XML
> files (update done in NIFI-10616 is not sufficient: ho header ignored,
> {{META-INF/JAXB/episode_*.xjb}} still contain header comments with
> timestamp): classical solution exists
> https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/doc/BUILDSPEC.md#avoiding-timestamps-in-jaxb-generated-content
> - war files suffer from jspc and documentation issues
> - a few jar suffer from swagger-generated issues: timestamp in generated
> annotation
> - 2 jar files suffer from META-INF/DEPENDENCIES generation
> the 2 first issues are the most noisy and can be fixed: let's define this as
> an objective for next release
> the 3 last ones are less common and impact less content: we'll see them
> later...
