Here’s what happened in the Reproducible Builds effort between Sunday January 29 and Saturday February 4 2017:
On February 1st, stretch/armhf reached 90% reproducible packages in our test framework, so that now all four tested architectures are ≥ 90% reproducible in stretch. Yay! For armhf this means 22472 reproducible source packages (in main); for amd64, arm64 and i386 these figures are 23363, 23062 and 22607 respectively.
Chris Lamb appeared on the Changelog podcast to talk about reproducible builds:
The Reproducible Build Zoo will be presented by Vagrant Cascadian at the Embedded Linux Conference in Portland, Oregon, February 22nd.
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
We learned that the “slightly more secure” Heads firmware (a Coreboot payload) is now reproducibly built regardless of host system or build directory. A picture says more than a thousand words:
Docker started preliminary work on making image builds reproducible.
Toolchain development and fixes
Ximin Luo continued to write code and test
cases for the
BUILD_PATH_PREFIX_MAP environment variable. He also did extensive research on
cross-platform and cross-language issues with environment variables, filesystem
paths, and character encodings, and started preparing a draft specification
document to describe all of this.
Chris Lamb asked CPython to implement an environment variable
PYTHONREVERSEDICTKEYORDER to add an
an option to reverse iteration order of items in a
dict. However this was
rejected because they are planning to formally fix this order in the next
Bernhard Wiedemann and Florian Festi added
support for our
SOURCE_DATE_EPOCH environment variable, to the RPM Package Manager.
Chris Lamb added documentation to diffoscope, strip-nondeterminism, disorderfs, reprotest and trydiffoscope about uploading signed tarballs when releasing. He also added a link to these on our website’s tools page.
