Freexian Collaborators: Debian Contributions: Python 3.12 preparations, debian-printing, merged-/usr tranisition updates, and more! (by Utkarsh Gupta)

Contributing to Debian is part of Freexian s mission. This article covers the latest achievements of Freexian and their collaborators. All of this is made possible by organizations subscribing to our Long Term Support contracts and consulting services.

Preparing for Python 3.12 by Stefano Rivera Stefano uploaded a few packages in preparation for Python 3.12, including pycxx and cython. Cython has a major new version (Cython 3), adding support for 3.12, but also bringing changes that many packages in Debian aren t ready to build with, yet. Stefano uploaded it to Debian experimental and did an archive rebuild of affected packages, and some analysis of the result. Matthias Klose has since filed bugs for all of these issues.

debian-printing, by Thorsten Alteholz This month Thorsten invested some of the previously obtained money to build his own printlab. At the moment it only consists of a dedicated computer with an USB printer attached. Due to its 64GB RAM and an SSD, building of debian-printing packages is much faster now. Over time other printers will be added and understanding bugs should be a lot easier now. Also Thorsten again adopted two packages, namely mink and ink, and moved them to the debian-printing team.

Merged-/usr transition by Helmut Grohne, et al The dumat analysis tool has been improved in quite some aspects. Beyond fixing false negative diagnostics, it now recognizes protective diversions used for mitigating Multi-Arch: same file loss. It was found that the proposed mitigation for ineffective diversions does not work as expected. Trying to fix it up resulted in more problems, some of which remain unsolved as of this writing. Initial work on moving shared libraries in the essential set has been done. Meanwhile, the wider Debian community worked on fixing all known Multi-Arch: same file loss scenarios. This work is now being driven by Christian Hofstaedler and during the Mini DebConf in Cambridge, Chris Boot, tienne Mollier, Miguel Landaeta, Samuel Henrique, and Utkarsh Gupta sent the other half of the necessary patches.

Miscellaneous contributions
  • Stefano merged patches to support loong64 and hurd-amd64 in re2.
  • For the Cambridge mini-conf, Stefano added a web player to the DebConf video streaming frontend, as the Cambridge miniconf didn t have its own website to host the player.
  • Rapha l helped the upstream developers of hamster-time-tracker to prepare a new upstream release (the first in multiple years) and packaged that new release in Debian unstable.
  • Enrico joined Hemut in brainstorming some /usr-merge solutions.
  • Thorsten took care of RM-bugs to remove no longer needed packages from the Debian archive and closed about 50 of them.
  • Helmut ported the feature of mounting a fuse connection via /dev/fd/N from fuse3 to fuse2.
  • Helmut sent a number of patches simplifying unprivileged use of piuparts.
  • Roberto worked with Helmut to prepare the Shorewall package for the ongoing /usr-move transition.
  • Utkarsh also helped with the ongoing /usr-merge work by preparing patches for gitlab, libnfc, and net-tools.
  • Utkarsh, along with Helmut, brainstormed on fixing #961138, as this affects the whole archive and all the suites and not just R packages. Utkarsh intends to follow up on the bug in December.
  • Santiago organized a MiniDebConf in Uruguay. In total, nine people attended, including most of DDs in the surrounding area. Here s a nicely written blog by Gunnar Wolf.
  • Santiago also worked on some issues on Salsa CI, fixed with some merge requests: #462, #463, and #466.

Lunar: Reproducible builds: week 9 in Stretch cycle

What happened about the reproducible builds effort this week: Toolchain fixes Norbert Preining uploaded texinfo/6.0.0.dfsg.1-2 which makes texinfo indices reproducible. Original patch by Chris Lamb. Lunar submitted recently rebased patches to make the file order of files inside .deb stable. akira filled #789843 to make tex4ht stop printing timestamps in its HTML output by default. Dhole wrote a patch for xutils-dev to prevent timestamps when creating gzip compresed files. Reiner Herrmann sent a follow-up patch for wheel to use UTC as timezone when outputing timestamps. Mattia Rizzolo started a discussion regarding the failure to build from source of subversion when -Wdate-time is added to CPPFLAGS which happens when asking dpkg-buildflags to use the reproducible profile. SWIG errors out because it doesn't recognize the aforementioned flag. Trying to get the .buildinfo specification to more definitive state, Lunar started a discussion on storing the checksums of the binary package used in dpkg status database. akira discovered while proposing a fix for simgrid that CMake internal command to create tarballs would record a timestamp in the gzip header. A way to prevent it is to use the GZIP environment variable to ask gzip not to store timestamps, but this will soon become unsupported. It's up for discussion if the best place to fix the problem would be to fix it for all CMake users at once. Infrastructure-related work Andreas Henriksson did a delayed NMU upload of pbuilder which adds minimal support for build profiles and includes several fixes from Mattia Rizzolo affecting reproducibility tests. Neils Thykier uploaded lintian which both raises the severity of package-contains-timestamped-gzip and avoids false positives for this tag (thanks to Tomasz Buchert). Petter Reinholdtsen filled #789761 suggesting that how-can-i-help should prompt its users about fixing reproducibility issues. Packages fixed The following packages became reproducible due to changes in their build dependencies: autorun4linuxcd, libwildmagic, lifelines, plexus-i18n, texlive-base, texlive-extra, texlive-lang. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues but not all of them: Untested uploaded as they are not in main: Patches submitted which have not made their way to the archive yet: debbindiff development debbindiff/23 includes a few bugfixes by Helmut Grohne that result in a significant speedup (especially on larger files). It used to exhibit the quadratic time string concatenation antipattern. Version 24 was released on June 23rd in a hurry to fix an undefined variable introduced in the previous version. (Reiner Herrmann) debbindiff now has a test suite! It is written using the PyTest framework (thanks Isis Lovecruft for the suggestion). The current focus has been on the comparators, and we are now at 93% of code coverage for these modules. Several problems were identified and fixed in the process: paths appearing in output of javap, readelf, objdump, zipinfo, unsqusahfs; useless MD5 checksum and last modified date in javap output; bad handling of charsets in PO files; the destination path for gzip compressed files not ending in .gz; only metadata of cpio archives were actually compared. stat output was further trimmed to make directory comparison more useful. Having the test suite enabled a refactoring of how comparators were written, switching from a forest of differences to a single tree. This helped removing dust from the oldest parts of the code. Together with some other small changes, version 25 was released on June 27th. A follow up release was made the next day to fix a hole in the test suite and the resulting unidentified leftover from the comparator refactoring. (Lunar) Documentation update Ximin Luo improved code examples for some proposed environment variables for reference timestamps. Dhole added an example on how to fix timestamps C pre-processor macros by adding a way to set the build date externally. akira documented her fix for tex4ht timestamps. Package reviews 94 obsolete reviews have been removed, 330 added and 153 updated this week. Hats off for Chris West (Faux) who investigated many fail to build from source issues and reported the relevant bugs. Slight improvements were made to the scripts for editing the review database, edit-notes and clean-notes. (Mattia Rizzolo) Meetings A meeting was held on June 23rd. Minutes are available. The next meeting will happen on Tuesday 2015-07-07 at 17:00 UTC. Misc. The Linux Foundation announced that it was funding the work of Lunar and h01ger on reproducible builds in Debian and other distributions. This was further relayed in a Bits from Debian blog post.

Christian Perrier: Bug #740000

Miguel Landaeta reported Debian bug #740000 on Monday February 24th, against the checkstyle package. Bug #730000 was reported as of November 20th: 3 months and 4 days for 10,000 bugs. Nearly exactly same bug reporting rate than 720000-730000. And, of course, we're still on our way to bug #800000 and bug #1000000.

Niels Thykier: Kudos to Jakub Adam, Miguel Landaeta and James Page

Credit where it is due and I believe it is due for Jakub Adam for packaging eclipse packages. If you use any of the eclipse packages provided the apt repositories for Wheezy or sid, it is very likely you have Jakub Adam to thank for it. I also believe that Miguel Landaeta and James Page deserve praise for their work. Miguel is to thank for the removal of libservlet2.4-java and updating its reverse dependencies not in that order ;-) . James Page, on the other hand, has been introducing and updating a lot of packages, noticeably the jenkins packages. Thank you and keep up the good work.
