What happened in the Reproducible Builds effort between Sunday September 25 and Saturday October 1 2016: Statistics For the first time, we reached 91% reproducible packages in our testing framework on testing/amd64 using a determistic build path. (This is what we recommend to make packages in Stretch reproducible.) For unstable/amd64, where we additionally test for reproducibility across different build paths we are at almost 76% again. IRC meetings We have a poll to set a time for a new regular IRC meeting. If you would like to attend, please input your available times and we will try to accommodate for you. There was a trial IRC meeting on Friday, 2016-09-31 1800 UTC. Unfortunately, we did not activate meetbot. Despite this participants consider the meeting a success as several topics where discussed (eg changes to IRC notifications of tests.r-b.o) and the meeting stayed within one our length. Upcoming events Reproduce and Verify Filesystems - Vincent Batts, Red Hat - Berlin (Germany), 5th October, 14:30 - 15:20 @ LinuxCon + ContainerCon Europe 2016. From Reproducible Debian builds to Reproducible OpenWrt, LEDE & coreboot - Holger "h01ger" Levsen and Alexander "lynxis" Couzens - Berlin (Germany), 13th October, 11:00 - 11:25 @ OpenWrt Summit 2016. Introduction to Reproducible Builds - Vagrant Cascadian will be presenting at the SeaGL.org Conference In Seattle (USA), November 11th-12th, 2016. Previous events GHC Determinism - Bartosz Nitka, Facebook - Nara (Japan), 24th September, ICPF 2016. Toolchain development and fixes Michael Meskes uploaded bsdmainutils/9.0.11 to unstable with a fix for #830259 based on Reiner Herrmann's patch. This fixed locale_dependent_symbol_order_by_lorder issue in the affected packages (freebsd-libs, mmh). devscripts/2.16.8 was uploaded to unstable. It includes a debrepro script by Antonio Terceiro which is similar in purpose to reprotest but more lightweight; specific to Debian packages and without support for virtual servers or configurable variations. Packages reviewed and fixed, and bugs filed The following updated packages have become reproducible in our testing framework after being fixed:

• ara/1.0.32 by Chris Lamb, original patch by Chris Lamb.
• fracplanet/0.4.0-5 by Chris Lamb, original patch by Reiner Herrman.

• Removed locale_dependent_symbol_order_by_lorder, fixed in bsdmainutils/9.0.11.
• Updated diffoscope_runs_forever, captures_build_path.

Weekly QA work As part of reproducibility testing, FTBFS bugs have been detected and reported by:

• Adrian Bunk (3)
• Chris Lamb (12)
• Lucas Nussbaum (3)
• Sebastian Reichel (1)

diffoscope development A new version of diffoscope 61 was uploaded to unstable by Chris Lamb. It included contributions from:

• Ximin Luo:
  • Improve the CLI --help text and add an --output-empty option.
• Chris Lamb:
  • Add a progress bar and show it if stdout is a TTY. You can read more about it here. It can also be read by higher-level programs via the --status-fd CLI option.
• Maria Glukhova:
  • Behaviour improvements in the case of OS-level errors.
• Mattia Rizzolo:
  • Testing and packaging improvements.

Post-release there were further contributions from:

• Chris Lamb:
  • Code architecture improvements.
• Maria Glukhova:
  • Testing improvements.

reprotest development A new version of reprotest 0.3.2 was uploaded to unstable by Ximin Luo. It included contributions from:

• Ximin Luo:
  • Add a --diffoscope-arg CLI option to pass extra args to diffoscope.

Post-release there were further contributions from:

• Chris Lamb:
  • Code quality improvements.

tests.reproducible-builds.org

• Hans-Christoph Steiner continued work on setting up reproducible tests for F-Droid.
• Holger cleaned up the script creating the page showing breakages, so that it now also cleans up some of the breakage it finds.
• IRC notifications about diffoscope crashes and artifacts available for investigations have been dropped; instead the breakages page has a permanent pointer. (h01ger)
• IRC notifications from the automatic package scheduler and status changes for packages have been moved -- as a temporary trial -- to #debian-reproducible-changes on irc.oftc.net (Mattia).

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

tests.reproducible-builds.org pbuilder has been updated to the last version to be able to support Build-Depends-Arch and Build-Conflicts-Arch. (Mattia Rizzolo, h01ger) New package sets have been added for Subgraph OS, which is based on Debian Stretch: packages and build dependencies. (h01ger) Two new armhf build nodes have been added (thanks Vagrant Cascadian) and integrated in our Jenkins setup with 8 new armhf builder jobs. (h01ger)

strip-nondeterminism development strip-nondeterminism version 0.016-1 was released on Sunday 28th. It will now normalize the POT-Creation-Date field in GNU Gettext .mo files. (Reiner Herrmann) Several improvements to the packages metadata have also been made. (h01ger, Ben Finney)

tests.reproducible-builds.org The reproducibly tests for Debian now vary the provider of /bin/sh between bash and dash. (Reiner Herrmann)

diffoscope development diffoscope version 50 was released on February 27th. It adds a new comparator for PostScript files, makes the directory tests pass on slower hardware, and line ordering variations in .deb md5sums files will not be hidden anymore. Version 51 uploaded the next day re-added test data missing from the previous tarball. diffoscope is looking for a new primary maintainer.

Package reviews 87 reviews have been removed, 61 added and 43 updated in the previous week. New issues: captures_shell_variable_in_autofoo_script, varying_ordering_in_data_tar_gz_or_control_tar_gz. 30 new FTBFS have been reported by Chris Lamb, Antonio Terceiro, Aaron M. Ucko, Michael Tautschnig, and Tobias Frost.

Misc. The release team reported on their discussion about the topic of rebuilding all of Stretch to make it self-contained (in respect to reproducibility). Christian Boltz is hoping someone could talk about reproducible builds at the openSUSE conference happening June 22nd-26th in N rnberg, Germany.

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donators (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it s one of the best ways to find volunteers to work with me on projects that matter to me. Debian LTS This month I have been paid to work 6.5 hours on Debian LTS. In that time I did the following:

• Prepared and released DLA-301-1 fixing 2 CVE in python-django.
• Did one week of LTS Frontdesk with CVE triaging. I pushed 11 commits to the security tracker.

Apart from that, I also gave a talk about Debian LTS at DebConf 15 in Heidelberg and also coordinated a work session to discuss our plans for Wheezy. Have a look at the video recordings:

• Debian Long Term Support: Past Present and Future (slides)
• Preparing for Wheezy LTS

DebConf 15 I attended DebConf 15 with great pleasure after having missed DebConf 14 last year. While I did not do lots of work there, I participated in many discussions and I certainly came back with a renewed motivation to work on Debian. That s always good. For the concrete work I did during DebConf, I can only claim two schroot uploads to fix the lack of support of the new overlay filesystem that replaces aufs in the official Debian kernel, and some Distro Tracker work (fixing an issue that some people had when they were logged in via Debian s SSO). While the numerous discussions I had during DebConf can t be qualified as work , they certainly contribute to build up work plans for the future: As a Kali developer, I attended multiple sessions related to derivatives (notably the Debian Derivatives Panel). I was also interested by the Debian in the corporate IT BoF led by Michael Meskes (Credativ s CEO). He pointed out a number of problems that corporate users might have when they first consider using Debian and we will try to do something about this. Expect further news and discussions on the topic. Martin Kraff, Luca Filipozzi, and me had a discussion with the Debian Project Leader (Neil) about how to revive/transform the Debian s Partner program. Nothing is fleshed out yet, but at least the process initiated by the former DPL (Lucas) is again moving forward. Other Debian work Sponsorship. I sponsored an NMU of pep8 by Daniel Stender as it was a requirement for prospector which I also sponsored since all the required dependencies are now available in Debian. \o/ Packaging. I NMUed libxml2 2.9.2+really2.9.1+dfsg1-0.1 fixing 3 security issues and a RC bug that was breaking publican. Since there s no upstream fix for more than 8 months, I went back to the former version 2.9.1. It s in line with the new requirement of release managers a package in unstable should migrate to testing reasonably quickly, it s not acceptable to keep it unfixed for months. With this annoying bug fixed, I could again upload a new upstream release of publican so I prepared and uploaded 4.3.2-1. It was my first source only upload. This release was more work than I expected and I filed no less than 3 bug to upstream (new bash-completion install path, request to provide sources of a minified javascript file, drop a .po file for an invalid language code). GPG issues with smartcard. Back from DebConf, when I wanted to sign some key, I stumbled again upon the problem which makes it impossible for me to use my two smartcards one after the other without first deleting the stubs for the private key. It s not a new issue but I decided that it was time to report it upstream, so I did it: #2079 on bugs.gnupg.org. Some research helped me to find a way to work-around the problem. Later in the month, after a dist-upgrade and a reboot, I was no longer able to use my smartcard as a SSH authentication key again it was already reported but there was no clear analysis, so I tried to do my own one and added the results of my investigation in #795368. It looks like the culprit is pinentry-gnome3 not working when started by the gpg-agent which is started before the DBUS session. Simple fix is to restart the gpg-agent in the session but I have no idea yet of what the proper fix should be (letting systemd manage the graphical user session and start gpg-agent would be my first answer, but that doesn t solve the issue for users of other init systems so it s not satisfying). Distro Tracker. I merged two patches from Orestis Ioannou fixing some bugs tagged newcomer. There are more such bugs (I even filed two: #797096 and #797223), go grab them and do a first contribution to Distro Tracker like Orestis just did! I also merged a change from Christophe Siraut who presented Distro Tracker at DebConf. I implemented in Distro Tracker the new authentication based on SSL client certificates that was recently announced by Enrico Zini. It s working nice, and this authentication scheme is far easier to support. Good job, Enrico! tracker.debian.org broke during DebConf, it stopped being updated with new data. I tracked this down to a problem in the archive (see #796892). Apparently Ansgar Burchardt changed the set of compression tools used on some jessie repositorie, replacing bz2 by xz. He dropped the old Packages.bz2 but missed some Sources.bz2 which were thus stale and APT reported Hashsum mismatch on the uncompressed content. Misc. I pushed some small improvement to my Salt formulas: schroot-formula and sbuild-formula. They will now auto-detect which overlay filesystem is available with the current kernel (previously aufs was hardcoded). Thanks See you next month for a new summary of my activities.

For Debian s birthday, Francesca Ciceri of the Debian Publicity team suggested that developers blog about their first experiences with Debian . I found this a good idea so I m going to share my own early experience. It s quite different from what happens nowadays Before speaking of my early Debian experience, I have to set some context. In my youth, I have always been a Windows user and a fan of Bill Gates. That is until I got Internet at home at that point, I got involved in Usenet and made some friends there. One of those made me discover Perl and it has been somewhat of a revelation for me who had only been programming in Visual Basic, Delphi or ObjectPal. Later the same friend explained me that Perl was working much better on Linux and that Debian Linux installs it by default so I should try this one. I had no idea of what Linux was, but given how I loved Perl, I was eager to try his advice. So I got myself a Tri-Linux CD with Debian/RedHat/Slackware on it and started the installation process (which involved preparing boot floppies). But I did not manage to get the graphical interface working despite lots of fiddling with Xfree86 s configuration file. So I ended up installing RedHat and used it for a few months. But since many of the smart guys in my Usenet community were Debian users, I persisted and finally managed to get it to work! After a few months of usage, I was amazed at everything that was available for free and I wanted to give back. I filed my first bug report in July 1998, I created my first Debian packages in August 1998 and I got accepted as an official Debian developer in September 1998 (after a quick chat over the phone with Martin Schulze or James Troup I never understood the name of my interlocutor on the phone and I was so embarassed to have to use my rusty English over the phone that I never asked). That s right, it took me less than 3 months to become a Debian developer (I was 19 years old back then). I learned a lot during those months by reading and interacting with other Debian developers. Many of those went away from Debian in the mean time but some of them are still involved (Joey Hess, Manoj Srivastava, Ian Jackson, Martin Schulze, Steve McIntyre, Bdale Garbee, Adam Heath, John Goerzen, Marco D Itri, Phil Hands, Lars Wirzenius, Santiago Vila, Matthias Klose, Dan Jacobowitz, Michael Meskes, ). My initial Debian work was centered around Perl: I adopted dpkg-ftp (the FTP method for dselect) because it was written in Perl and had lots of outstanding bug reports. But I also got involved in more generic Quality Assurance work and tried to organize the nascent QA team. It was all really a lot of fun, I could take initiatives and it was clear to me that my work was appreciated. I don t know if you find this story interesting but I had some fun time digging through archives to find out the precise dates if you want to learn more about what I did over the following years, I maintain a webpage for this purpose.

This morning, I ranted about uncoordinated introduction of debconf templates. It happens that part of my rant went on citadel maintainers, at least one of which (Michael Meskes) being someone I have good respect for his work in Debian...and who's generally translators-aware. He bringed me an interesting argument to explain why the maintenance team did not call for translations and templates review before uploading the new package: NEW processing. They weren't apparently so sure about the package being accepted and, thus, did not want to add extra work for nothing. So, they first wanted to get the package in the archive before working on other stuff. This is indeed a valid objection to my rant and I very happily post apologies for this rant as Michael promised me he would call for review/translations just now. I still think that new packages with debconf templates should ask for a review in debian-l10n-english, though..:-)
