Here's what happened in the [Reproducible
Builds](https://wiki.debian.org/ReproducibleBuilds) effort between Sunday
January 29 and Saturday February 4 2017:
Media coverage
--------------
Dennis Gilmore and Holger Levsen presented "Reproducible Builds and Fedora"
([Video](https://www.youtube.com/watch?v=d8oEg0p6QLE),
[Slides](http://reproducible.alioth.debian.org/presentations/2017-01-27-devconf.cz-reproducible-builds+fedora.pdf))
at [Devconf.cz](https://devconf.cz/) on February 27th 2017.
On February 1st,
[stretch/armhf](https://tests.reproducible-builds.org/debian/testing/index_suite_armhf_stats.html)
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](https://changelog.com/podcast/237) to talk about reproducible builds:
Holger Levsen pitched Reproducible Builds and our need for a
[logo](https://wiki.debian.org/ReproducibleBuilds/Logo) in the "Open Source Design"
room at FOSDEM 2017
([Video](https://video.fosdem.org/2017/AW1.121/osd_pitch_your_project.mp4),
09:36 - 12:00).
Upcoming Events
---------------
- [The Reproducible Build
Zoo](https://openiotelcna2017.sched.com/event/9Iu4/the-reproducible-build-zoo-vagrant-cascadian-aikidev-llc)
will be presented by Vagrant Cascadian at the Embedded Linux Conference in
Portland, Oregon, February 22nd.
- [Introduction to Reproducible
Builds](https://www.socallinuxexpo.org/scale/15x/presentations/introduction-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](https://www.libreplanet.org/2017/) in Boston,
March 25th-26th.
Reproducible work in other projects
-----------------------------------
We learned that the "slightly more secure" [Heads
firmware](https://github.com/osresearch/heads) (a Coreboot payload) [is now
reproducibly built regardless of host system or build
directory](https://twitter.com/qrs/status/826060202042494976/photo/1).
A picture says more than a thousand words:
[](/blog/images/reproducible-heads-firmware-20170131.jpg)
Docker started [preliminary work](https://github.com/docker/docker/pull/30611)
on making image builds reproducible.
Toolchain development and fixes
-------------------------------
Ximin Luo continued to write [code and test
cases](https://github.com/infinity0/rb-prefix-map) 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](http://bugs.python.org/issue29431) 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
language version.
Bernhard Wiedemann and Florian Festi [added
support](https://github.com/rpm-software-management/rpm/pull/143) for our
`SOURCE_DATE_EPOCH` environment variable, to the RPM Package Manager.
James McCoy uploaded [devscripts](https://tracker.debian.org/pkg/devscripts) 2.17.1 with a change from Guillem
Jover for `dscverify(1)`, adding support for .buildinfo files. (Closes: [#852801](https://bugs.debian.org/852801))
Piotr Ożarowski uploaded [dh-python](https://tracker.debian.org/pkg/dh-python) 2.20170125 with a change from Chris
Lamb for a patch to fix [#835805](https://bugs.debian.org/835805).
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](https://reproducible-builds.org/tools/).
