Reproducible Builds Hackathon Hamburg 2017
The Reproducible Builds Hamburg Hackathon 2017, or RB-HH-2017 for short is a 3 day hacking event taking place May 5th-7th in the CCC Hamburg Hackerspace located inside Frappant, as collective art space located in a historical monument in Hamburg, Germany.
The aim of the hackathon is to spent some days working on Reproducible Builds in every distribution and project. The event is open to anybody interested on working on Reproducible Builds issues, with or without prior experience!
Accommodation is available and travel sponsorship may be available by agreement. Please register your interest as soon as possible.
Reproducible Builds Summit Berlin 2016
Request For Comments for new specification:
Ximin Luo posted a draft
version of our
BUILD_PATH_PREFIX_MAP specification for passing build-time paths between
high-level and low-level build tools. This is meant to help eliminate
irreproducibility caused by different paths being used at build time. At the
time of writing, this affects an estimated 15-20% of 25000 Debian packages.
This is a continuation of an older proposal
SOURCE_PREFIX_MAP, which has been
updated based on feedback on our patches from GCC upstream, attendees of our
Berlin 2016 summit, and participants on our mailing list. Thanks to everyone
The specification also contains runnable source code examples and test cases; see our git repo.
Please comment on this draft ASAP - we plan to release version 1.0 of this in a few weeks.

Weekly QA work
During our reproducibility testing, FTBFS bugs have been detected and reported by:
- Chris Lamb (5)
- Mattia Rizzolo (1)
diffoscope 79 and 80 were uploaded to experimental by Chris Lamb. It included contributions from:
- Ensure that we really are using ImageMagick. (Closes: #857940)
- Extract SquashFS images in one go rather than per-file, speeding up (eg.) Tails ISO comparison by ~10x.
- Support newer versions of cbfstool to avoid test failures. (Closes: #856446)
- Skip icc test that varies on endian if the Debian-specific patch is not present. (Closes: #856447)
- Compare GIF images using gifbuild. (Closes: #857610)
- Various other code quality, build and UI improvements.
- Improve AndroidManifest.xml comparison for APK files. (Closes: #850758)
strip-nondeterminism 0.032-1 was uploaded to unstable by Chris Lamb. It included contributions from:
- Fix a possible endless loop while stripping ar files due to trusting the file’s file size data. Thanks to Tobias Stoeckmann for the report, patch and testcase. (Closes: #857975)
- Add support for testing files we should reject.
Holger setup a jenkins job to build build-path-prefix-map-spec.git on every commit, producing nice a HTML version of the BUILD_PATH_PREFIX_MAP specification
Some more tuning was done on IRC notifications by Holger.
For testing Debian, diffoscope from experimental is now used, if available. (Holger too)
Updated PyPI version check for diffoscope (Chris Lamb)
This week’s edition was written by Ximin Luo, Holger Levsen and Chris Lamb & reviewed by a bunch of Reproducible Builds folks on IRC & the mailing lists.
