Welcome to the December 2022 report from the Reproducible Builds project.

---

We are extremely pleased to announce that the dates for the Reproducible Builds Summit in 2023 have been announced in 2022 already:

• When: October 31st, November 1st, November 2nd 2023.
• Where: Dock Europe, Hamburg, Germany.

We plan to spend three days continuing to the grow of the Reproducible Builds effort. As in previous events, the exact content of the meeting will be shaped by the participants. And, as mentioned in Holger Levsen s post to our mailing list, the dates have been booked and confirmed with the venue, so if you are considering attending, please reserve these dates in your calendar today.

R my Gr nblatt, an associate professor in the T l com Sud-Paris engineering school wrote up his pain points of using Nix and NixOS. Although some of the points do not touch on reproducible builds, R my touches on problems he has encountered with the different kinds of reproducibility that these distributions appear to promise including configuration files affecting the behaviour of systems, the fragility of upstream sources as well as the conventional idea of binary reproducibility.

---

Morten Linderud reported that he is quietly optimistic that if Go programming language resolves all of its issues with reproducible builds (tracking issue) then the Go binaries distributed from Google and by Arch Linux may be bit-for-bit identical. It s just a bit early to sorta figure out what roadblocks there are. [But] Go bootstraps itself every build, so in theory I think it should be possible.

---

On December 15th, Holger Levsen published an in-depth interview he performed with David A. Wheeler on supply-chain security and reproducible builds, but it also touches on the biggest challenges in computing as well. This is part of a larger series of posts featuring the projects, companies and individuals who support the Reproducible Builds project. Other instalments include an article featuring the Civil Infrastructure Platform project and followed this up with a post about the Ford Foundation as well as a recent ones about ARDC, the Google Open Source Security Team (GOSST), Jan Nieuwenhuizen on Bootstrappable Builds, GNU Mes and GNU Guix and Hans-Christoph Steiner of the F-Droid project.

---

A number of changes were made to the Reproducible Builds website and documentation this month, including FC Stegerman adding an F-Droid/apksigcopier example to our embedded signatures page [ ], Holger Levsen making a large number of changes related to the 2022 summit in Venice as well as 2023 s summit in Hamburg [ ][ ][ ][ ] and Simon Butler updated our publications page [ ][ ].

---

On our mailing list this month, James Addison asked a question about whether there has been any effort to trace the files used by a build system in order to identify the corresponding build-dependency packages. [ ] In addition, Bernhard M. Wiedemann then posed a thought-provoking question asking How to talk to skeptics? , which was occasioned by a colleague who had published a blog post in May 2021 skeptical of reproducible builds. The thread generated a number of replies.

Android news obfusk (FC Stegerman) performed a thought-provoking review of tools designed to determine the difference between two different .apk files shipped by a number of free-software instant messenger applications. These scripts are often necessary in the Android/APK ecosystem due to these files containing embedded signatures so the conventional bit-for-bit comparison cannot be used. After detailing a litany of issues with these tools, they come to the conclusion that:

It s quite possible these messengers actually have reproducible builds, but the verification scripts they use don t actually allow us to verify whether they do.

This reflects the consensus view within the Reproducible Builds project: pursuing a situation in language or package ecosystems where binaries are bit-for-bit identical (over requiring a bespoke ecosystem-specific tool) is not a luxury demanded by purist engineers, but rather the only practical way to demonstrate reproducibility. obfusk also announced the first release of their own set of tools on our mailing list. Related to this, obfusk also posted to an issue filed against Mastodon regarding the difficulties of creating bit-by-bit identical APKs, especially with respect to copying v2/v3 APK signatures created by different tools; they also reported that some APK ordering differences were not caused by building on macOS after all, but by using Android Studio [ ] and that F-Droid added 16 more apps published with Reproducible Builds in December.

Debian As mentioned in last months report, Vagrant Cascadian has been organising a series of online sprints in order to clear the huge backlog of reproducible builds patches submitted by performing NMUs (Non-Maintainer Uploads). During December, meetings were held on the 1st, 8th, 15th, 22nd and 29th, resulting in a large number of uploads and bugs being addressed:

• Chris Lamb: aespipe (#661079, #1020809), cdbackup (#1011428) & xmlrpc-epi (#865688, #1020651)
• Holger Levsen: apr-util (#1006865), lirc (#979024) & ruby-omniauth-tumblr
• Vagrant Cascadian: amavisd-milter (#975954), apophenia (#940013), cfi (#995647), chessx (#881664), cmocka (#991181), desmume (#890312), golang-gonum-v1-plot (#968045), intel-gpu-tools (#945105), jhbuild (#971420), libjama (#986601), libjs-qunit (#976445), liblip (#1001513, #989583), libstatgrab (#961747), mlpost (#977179 and #977180), netcdf-parallel (#972930), netgen-lvs (#955783), perfect-scrollbar (#1000770), python-tomli (#994979), pytsk (#992060), smplayer (#997689), squeak-plugins-scratch (#876771, #942006), stgit (#942009), strace (#896016), surgescript (#992061), sympow (#973601), wxmaxima (#983148), xavs2 (#952493), xaw3d (#991180, #986704) and yard (#972668).

The next sprint is due to take place this coming Tuesday, January 10th at 16:00 UTC.

Upstream patches The Reproducible Builds project attempts to fix as many currently-unreproducible packages as possible. This month, we wrote a large number of such patches, including:

• Bernhard M. Wiedemann:
  • OpenRGB (filesystem ordering issue)
  • python-maturin (report an issue regarding random numbers)
  • rav1e (datetime-related issue)
  • weblate (report that the build fails in 2038)
• Chris Lamb:
  • #1025415 filed against cctools.
  • #1025801 filed against sphinx (forwarded upstream)
  • #1026381 filed against python-django-health-check.
  • #1026876 filed against jamin.
  • #1026877 filed against opari2.

---

Testing framework The Reproducible Builds project operates a comprehensive testing framework at tests.reproducible-builds.org in order to check packages and other artifacts for reproducibility. In October, the following changes were made by Holger Levsen:

• The osuosl167 machine is no longer a openqa-worker node anymore. [ ][ ]
• Detect problems with APT repository signatures [ ] and update a repository signing key [ ].
• reproducible Debian builtin-pho: improve job output. [ ]
• Only install the foot-terminfo package on Debian systems. [ ]

In addition, Mattia Rizzolo added support for the version of diffoscope in Debian stretch which doesn t support the --timeout flag. [ ][ ]

---

diffoscope diffoscope is our in-depth and content-aware diff utility. Not only can it locate and diagnose reproducibility issues, it can provide human-readable diffs from many kinds of binary formats. This month, Chris Lamb made the following changes to diffoscope, including preparing and uploading versions 228, 229 and 230 to Debian:

• Fix compatibility with file(1) version 5.43, with thanks to Christoph Biedl. [ ]
• Skip the test_html.py::test_diff test if html2text is not installed. (#1026034)
• Update copyright years. [ ]

In addition, Jelle van der Waa added support for Berkeley DB version 6. [ ] Orthogonal to this, Holger Levsen bumped the Debian Standards-Version on all of our packages, including diffoscope [ ], strip-nondeterminism [ ], disorderfs [ ] and reprotest [ ].

Here's what happened in the Reproducible Builds effort between Sunday June 4 and Saturday June 10 2017: Past and upcoming events On June 10th, Chris Lamb presented at the Hong Kong Open Source Conference 2017 on reproducible builds. Patches and bugs filed

• Chris Lamb: #864082 filed against fontconfig, forwarded upstream

Reviews of unreproducible packages 7 package reviews have been added, 10 have been updated and 14 have been removed in this week, adding to our knowledge about identified issues. Weekly QA work During our reproducibility testing, FTBFS bugs have been detected and reported by:

• Adrian Bunk (4)
• Chris Lamb (1)
• Christoph Biedl (1)
• Niko Tyni (1)

Two FTBFS issues of LEDE (exposed in our setup) were found and were fixed:

• build: ensure that flock is available for make download (Felix Fietkau)
• include/toplevel: set env GIT_ASKPASS=/bin/true (Alexander 'lynxis' Couzens)

diffoscope development

• Chris Lamb: Some code style improvements

tests.reproducible-builds.org: Alexander 'lynxis' Couzens made some changes for testing LEDE and OpenWrt:

• Build tar before downloading everything: On system without tar --sort=name we need to compile tar before downloading everything
• Set CONFIG_AUTOREMOVE to reduce required space
• Create a workaround for signing keys: LEDE signs the release with a signing key, but generates the signing key if it's not present. To have a reproducible release we need to take care of signing keys.
• openwrt_get_banner(): use staging_dir instead of build_dir because the former is persistent among the two builds.
• Don't build all packages to improve development speed for now.
• Only build one board instead of all boards. Reducing the build time improves developing speed. Once the image is reproducible we will enable more boards.
• Disable node_cleanup_tmpdirs

Hans-Christoph Steiner, for testing F-Droid:

• Do full git reset/clean like Jenkins does
• hard code WORKSPACE dir names, as WORKSPACE cannot be generated from $0 as it's a temporary name.

Daniel Shahaf, for testing Debian:

• Remote scheduler:
  • English fix to error message.
  • Allow multiple architectures in one invocation.
  • Refactor: Break out a helper function. Rename variable to disambiguate with scheduling_args.message.
• Include timestamps in logs
• Set timestamps to second resolution (was millisecond by default).

Holger 'h01ger' Levsen, for testing Debian:

• Improvements to the breakages page:
  • List broken packages and diffoscope problems first, and t.r-b.o problems last.
  • Reword, drop 'caused by'.
• Add niceness to our list of variations, running with niceness of 11 for the first build and niceness of 10 for the second one. Thanks to Vagrant for the idea.
• Automatic scheduler:
  • Reschedule after 12h packages that failed with error 404
  • Run scheduler every 3h instead of every 6h
• Add basic README about the infrastructure and merge Vagrants notes about his console host.

Misc. This week's edition was written by Ximin Luo, Chris Lamb and Holger Levsen & reviewed by a bunch of Reproducible Builds folks on IRC & the mailing lists.

Here's what happened in the Reproducible Builds effort between Sunday January 22 and Saturday January 28 2017: Media coverage

• The Reproducible Build Zoo was presented by Vagrant Cascadian at the Embedded Linux Conference in Portland, Oregon on February 22nd.
• Dennis Gilmore and Holger Levsen presented "Reproducible Builds and Fedora" at Devconf.cz on February 27th.

Upcoming Events

• Introduction to Reproducible Builds will be presented by Vagrant Cascadian at Scale15x in Pasadena, California, March 5th.
• "Verifying Software Freedom with Reproducible Builds" will be presented by Vagrant Cascadian at Libreplanet2017 in Boston, March 25th-26th.

Reproducible work in other projects John Gilmore wrote an interesting mail about how Cygnus.com worked on reproducible builds in the early 1990s. It's eye opening to see how the dealt with basically the very same problems we're dealing with today, how they solved them and then to realize that most of this has been forgotten and bit-rotted in the last 20 years. How will we prevent history repeating itself here? Toolchain development and fixes Christoph Biedl wrote a mail describing an interesting problem in to the way binNMUs are done in Debian. Guillem Jover made a number of changes to dpkg that affect the Reproducible Builds effort within Debian:

• Always set SOURCE_DATE_EPOCH in dpkg-buildpackage and dpkg-source. Use the current date if the changelog does not have one. Closes: #849081
• Add initial support for DEB_BUILD_OPTIONS to dpkg-genbuildinfo. This will make it possible to enable or disable specific features that should be recorded in the .buildinfo file. For now only all and path are supported. Closes: #848705
• Include .buildinfo files also for source-only uploads in dpkg-genchanges. Closes: #846164
• Add support for signed .buildinfo files to dpkg-buildpackage. Add new -ui and --unsigned-buildinfo options. Closes: #843925
• Make dpkg-buildpackage --unsigned-changes not sign .buildinfo either. This breaks the expectations of users and tools, because there was no way previously to request no signing at all. Closes: #852822

Packages reviewed and fixed, and bugs filed Chris Lamb:

• #852482 filed against flask-limiter.
• #853039 filed against fontypython.

Dhole:

• #852289 filed against python-passlib.

Reviews of unreproducible packages 17 package reviews have been added, 4 have been updated and 6 have been removed in this week, adding to our knowledge about identified issues. 2 issue types have been added:

• python_versioneer_uses_parentdir
• captures_kernel_version_via_CMAKE_SYSTEM

1 issue type has been removed:

• ftbfs_due_to_jenkins_semaphore_setup

Weekly QA work During our reproducibility testing, the following FTBFS bugs have been detected and reported by:

• Chris Lamb (6)
• Holger Levsen (1)

diffoscope development

• diffoscope 70 was uploaded to unstable by Mattia Rizzolo. It included contributions from:
• Chris Lamb:
  • tests.presenters: Prevent FTBFS by loading fixtures as UTF-8 in case surrounding terminal is not Unicode-aware. (Closes: #852926)
  • comparators: Tidy re_tests with list comprehensions and implicit "x, y" unpacking over indexing; lambda/filter is not idiomatic Python 3.
  • tests: Increase coverage by adding "# noqa" in relevant parts.
  • tests: Test that no arguments (beyond the filenames) prints the text output.
  • tests: Test --text-color output format.
  • tests: Add a test comparing two empty directories.
  • tests: Don't warn about coverage lines that raise NotImplementedError.
• anthraxx:
  • tools: switch Arch Linux dependency for pedump to mono
• Ximin Luo:
  • Fix lazy expression, filter is lazy in Python 3
  • Fix bug introduced in commit 36d1c964 that only worked "accidentally"

reprotest development

• reprotest 0.6 was uploaded to unstable by Holger Levsen. It included contributions:
• Ximin Luo:
  • Test the extra variations we added recently and ensure they don't get missed in the future
  • Better logging messages that actually get controlled by the verbosity flag
  • Add a man page using rst2man and help2man
  • Add a --config-file option and fix the loading of configs
  • Fix the reading of config options
  • Fix a bug where the sha256sum of a reproduction won't be displayed if --store-dir is not given

buildinfo.debian.net development

• Chris Lamb:
  • Show SHA256 checksums on larger displays
  • Move default storage to S3.
  • Store files directly onto S3.
  • Add tool to move data to S3.
  • Load data from S3 if we don't have it locally.

tests.reproducible-builds.org

• h01ger experimented with reusing SSH control connections but stopped that experiment when we ran into more network issues than before. To be continued, as we're having 10k SSH connections per day and saving 2 seconds each time would sum up, especially on the Jenkins host itself.
• h01ger made the scheduler run 3 times a day, 2.5h after dinstall runs, instead of every 3h as before.
• h01ger restructured the https://tests.reproducible-builds.org/debian/index_breakages.html and improved the corresponding Jenins job.
• h01ger also unblacklisted xmds2, sofia-sip and ck - if you think other packages should be unblacklisted (maybe only on some architectures), please do tell us.

What happened in the reproducible builds effort this week: Toolchain fixes

• Bdale Garbee uploaded tar/1.28-1 which includes the --clamp-mtime option. Patch by Lunar.

Aur lien Jarno uploaded glibc/2.21-0experimental1 which will fix the issue were locales-all did not behave exactly like locales despite having it in the Provides field. Lunar rebased the pu/reproducible_builds branch for dpkg on top of the released 1.18.2. This made visible an issue with udebs and automatically generated debug packages. The summary from the meeting at DebConf15 between ftpmasters, dpkg mainatainers and reproducible builds folks has been posted to the revelant mailing lists.

Patches submitted which have not made their way to the archive yet:

• #797027 on zyne by Chris Lamb: switch to pybuild to get rid of .pyc files.
• #797180 on python-doit by Chris Lamb: sort output when creating completion script for bash and zsh.
• #797211 on apt-dater by Chris Lamb: fix implementation of SOURCE_DATE_EPOCH.
• #797215 on getdns by Chris Lamb: fix call to dpkg-parsechangelog in debian/rules.
• #797254 on splint by Chris Lamb: support SOURCE_DATE_EPOCH for version string.
• #797296 on shiro by Chris Lamb: remove username from build string.
• #797408 on splitpatch by Reiner Herrmann: use SOURCE_DATE_EPOCH to set manpage date.
• #797410 on eigenbase-farrago by Reiner Herrmann: sets the comment style to scm-safe which tells ResourceGen that no timestamps should be included.
• #797415 on apparmor by Reiner Herrmann: sorting with the locale set to C. CAPABILITIES
• #797419 on resiprocate by Reiner Herrmann: set the embedded hostname to a static value.
• #797427 on jam by Reiner Herrmann: sorting with the locale set to C.
• #797430 on ii-esu by Reiner Herrmann: sort source list using C locale.
• #797431 on tatan by Reiner Herrmann: sort source list using C locale.

Chris Lamb also noticed that binaries shipped with libsilo-bin did not work. Documentation update Chris Lamb and Ximin Luo assembled a proper specification for SOURCE_DATE_EPOCH in the hope to convince more upstreams to adopt it. Thanks to Holger it is published under a non-Debian domain name. Lunar documented easiest way to solve issues with file ordering and timestamps in tarballs that came with tar/1.28-1. Some examples on how to use SOURCE_DATE_EPOCH have been improved to support systems without GNU date. reproducible.debian.net armhf is finally being tested, which also means the remote building of Debian packages finally works! This paves the way to perform the tests on even more architectures and doing variations on CPU and date. Some packages even produce the same binary Arch:all packages on different architectures (1, 2). (h01ger) Tests for FreeBSD are finally running. (h01ger) As it seems the gcc5 transition has cooled off, we schedule sid more often than testing again on amd64. (h01ger) disorderfs has been built and installed on all build nodes (amd64 and armhf). One issue related to permissions for root and unpriviliged users needs to be solved before disorderfs can be used on reproducible.debian.net. (h01ger) strip-nondeterminism Version 0.011-1 has been released on August 29th. The new version updates dh_strip_nondeterminism to match recent changes in debhelper. (Andrew Ayer) disorderfs disorderfs, the new FUSE filesystem to ease testing of filesystem-related variations, is now almost ready to be used. Version 0.2.0 adds support for extended attributes. Since then Andrew Ayer also added support to reverse directory entries instead of shuffling them, and arbitrary padding to the number of blocks used by files. Package reviews 142 reviews have been removed, 48 added and 259 updated this week. Santiago Vila renamed the not_using_dh_builddeb issue into varying_mtimes_in_data_tar_gz_or_control_tar_gz to align better with other tag names. New issue identified this week: random_order_in_python_doit_completion. 37 FTBFS issues have been reported by Chris West (Faux) and Chris Lamb. Misc. h01ger gave a talk at FrOSCon on August 23rd. Recordings are already online. These reports are being reviewed and enhanced every week by many people hanging out on #debian-reproducible. Huge thanks!

On Sunday I gave a talk about Debian LTS during the Mini-DebConf in Lyon. Obviously I presented the project and the way it s organized, but I also took the opportunity to compute some statistics. You can watch the presentation (thanks to the video team!) or have a look at the slides to learn more. Here are some extracts of the statistics I collected: The number of the uploads per affiliation (known affiliations are recorded in the LTS/Team wiki page) is displayed on the graph below. None corresponds to packages maintainers taking care of their own packages, Debian Security corresponds to members of the security team who also contributed to LTS, Debian LTS corresponds to individual members of the LTS team without any explicit affiliation. Freexian represents in fact 29 financial sponsors (see detail here). Top 12 contributors (in number of uploads):

• Thorsten Alteholz: 66
• Holger Levsen: 27
• Rapha l Hertzog: 14
• Rapha l Geissert: 13
• Thijs Kinkhorst: 8
• Kurt Roeck: 7
• Christoph Biedl: 7
• Nguyen Cong: 6
• Ben Hutchings: 6
• Michael Vogt: 5
• Moritz M hlenhoff: 4
• Matt Palmer: 4

The talk also contains explanations about the current funding setup. Hopefully this clears things up for people who were still wondering how the LTS project is working.
