Hello, This week I have been working on the following problems:
1. doxygen ----------- There was a new Debian doxygen release in unstable so I refreshed the version in the reproducible builds git repository and package repository. This took a bit longer because of the current libstdc++6 transition [1] which broke my system (I had to go use snapshot.d.o for a while) and because of two bugs I found in the process: - https://bugs.debian.org/794745 - https://bugs.debian.org/794758 2. camitk ---------- This package was wrongly tagged as suffering from timestamps_in_manpages_generated_by_doxygen [2]. The timestamps found in manpages were generated from a cmake script which has now been patched to use the environment variable $SOURCE_DATE_EPOCH [3] and packages.yml has been updated - https://bugs.debian.org/794740 3. gperf, maxima, and python-xlib ---------------------------------- These package were not affected by the latest texi2html release in unstable. When further investigated I found that they contained an embedded code copy of texi2html and they did not build-depend on the Debian texi2html. The copyright information of texi2html was missing from their debian/copyright. Package: gperf - https://bugs.debian.org/794955 Package: maxima - https://bugs.debian.org/795056 Package: python-xlib - https://bugs.debian.org/795057 4. texi2html ------------- I modified the patch made by Juan Picca for texi2html to use $SOURCE_DATE_EPOCH when it produces its timestamps [4], I have also patched texi2html to sort its hash values, which solves the issue randomness_in_html_generated_by_texi2html [5]. The package has been QA uploaded to unstable with these fixes. - https://bugs.debian.org/783475 I scheduled 19 packages affected by texi2html. Out of these 2 became immediately reproducible, up till now 3 were found to not build-depend on texi2html but include an embedded code copy (see above) and the rest do not use dh or CDBS as their build system and therefore $SOURCE_DATE_EPOCH does not get exported and cannot be used by texi2html. Individual patches are needed for these packages. 5. Unfinished ----------------- I have been working on making bash reproducible and discovered that it produces unreproducible pdf through a mechanism that has not been inventoried yet. It uses dvipdfm. I will work on this issue more this week. I am also working on making the timestamps produced by pdftex be timezone independent. This will complete my initial pdftex patch to make the CreationDate, ModDate and ID field deterministic in pdf generated by latex [6] Kind Regards, akira [1] https://release.debian.org/transitions/html/libstdc++6.html [2] https://reproducible.debian.net/issues/unstable/timestamps_in_manpages_generated_by_doxygen_issue.html [3] https://wiki.debian.org/ReproducibleBuilds/TimestampsProposal [4] https://reproducible.debian.net/issues/unstable/timestamps_in_documentation_generated_by_texi2html_issue.html [5] https://wiki.debian.org/ReproducibleBuilds/RandomnessInHTMLGeneratedByTexi2html [6] https://reproducible.debian.net/issues/unstable/timestamps_in_pdf_generated_by_latex_issue.html
