Lunar: Reproducible builds: week 41 in Stretch cycle

What happened in the reproducible builds effort this week:

Toolchain fixes After remarks from Guillem Jover, Lunar updated his patch adding generation of .buildinfo files in dpkg.

Packages fixed The following packages have become reproducible due to changes in their build dependencies: dracut, ent, gdcm, guilt, lazarus, magit, matita, resource-agents, rurple-ng, shadow, shorewall-doc, udiskie. The following packages became reproducible after getting fixed:
  • disque/1.0~rc1-5 by Chris Lamb, noticed by Reiner Herrmann.
  • dlm/4.0.4-2 by Ferenc W gner.
  • drbd-utils/8.9.6-1 by Apollon Oikonomopoulos.
  • java-common/0.54 by by Emmanuel Bourg.
  • libjibx1.2-java/1.2.6-1 by Emmanuel Bourg.
  • libzstd/0.4.7-1 by Kevin Murray.
  • python-releases/1.0.0-1 by Jan Dittberner.
  • redis/2:3.0.7-2 by Chris Lamb, noticed by Reiner Herrmann.
  • tetex-brev/4.22.github.20140417-3 by Petter Reinholdtsen.
Some uploads fixed some reproducibility issues, but not all of them:
  • anarchism/14.0-4 by Holger Levsen.
  • hhvm/3.11.1+dfsg-1 by Faidon Liambotis.
  • netty/1:4.0.34-1 by Emmanuel Bourg.
Patches submitted which have not made their way to the archive yet:
  • #813309 on lapack by Reiner Herrmann: removes the test log and sorts the files packed into the static library locale-independently.
  • #813345 on elastix by akira: suggest to use the $datetime placeholder in Doxygen footer.
  • #813892 on dietlibc by Reiner Herrmann: remove gzip headers, sort md5sums file, and sort object files linked in static libraries.
  • #813912 on git by Reiner Herrmann: remove timestamps from documentation generated with asciidoc, remove gzip headers, and sort md5sums and tclIndex files.

reproducible.debian.net For the first time, we've reached more than 20,000 packages with reproducible builds for sid on amd64 with our current test framework. Vagrant Cascadian has set up another test system for armhf. Enabling four more builder jobs to be added to Jenkins. (h01ger)

Package reviews 233 reviews have been removed, 111 added and 86 updated in the previous week. 36 new FTBFS bugs were reported by Chris Lamb and Alastair McKinstry. New issue: timestamps_in_manpages_generated_by_yat2m. The description for the blacklisted_on_jenkins issue has been improved. Some packages are also now tagged with blacklisted_on_jenkins_armhf_only.

Misc. Steven Chamberlain gave an update on the status of FreeBSD and variants after the BSD devroom at FOSDEM 16. He also discussed how jails can be used for easier and faster reproducibility tests. The video for h01ger's talk in the main track of FOSDEM 16 about the reproducible ecosystem is now available.

Jan Dittberner: CLT 2014 was great again

as in previous years we had a Debian booth at the Chemnitzer Linux-Tage it was as well organized as the years before and I enjoyed meeting a lot of great people from the Debian and free software communities as well as CAcert again. At our booth we presented the awesome work of Debian Installer translators in a BabelBox surrounded by xpenguins which attracted young as well as older passers-by. We got thanks for our work which I want to forward to the whole Debian community. A Debian user told us that he is able to use some PC hardware from the late 1990s that does not work with other desktop OSes anymore. We fed 3 kg of strategic jelly bear reserves as well as some packs of savoury snacks to our visitors. Alexander Wirt brought some T-Shirts, Stickers and Hoodies that we sold almost completely. We did some keysigning at the booth to help to get better keys into the Debian keyring and helped a prospective new Debian Developer to get a strong key signed to his FD approval. I also attended the Key signing party organized by Jens Kubieziel. Thanks to all people who helped at the booth:
  • Alexander Mundt
  • Alexander Wirt
  • Florian Baumann
  • Jan H rsch
  • Jan Wagner
  • Jonas Genannt
  • Rene Engelhard
  • Rhalina
  • Y Plentyn
Thanks to TMT for sponsoring the booth hardware.

Jan Dittberner: Going to Chemnitzer Linux-Tage 2014

This year I take care of organizing of the Debian booth at Chemnitzer Linux-Tage 2014 which has been approved a few days ago. The CLT is a yearly (mostly) german speaking Free Software community event which takes place on the weekend of 15th/16th march in Chemnitz (Germany). On the Linux-Live pages you find a lot of projects that will have a booth there and the talk schedule contains many interesting topics. There will also be a key signing event for which you can register until 11th of march. The Wiki page for the Event is already in a good shape. Many things are already organized, but we still have some items left. A lot of people from the Debian community have already told me that they will be there. We will have a Debian Wheezy BabelBox demonstration running on a VirtualBox host that Jan Wagner will provide as well as merchandising (Thanks to Alexander Wirt). Two talks from people on our Wiki page have been accepted by the CLT organizers too: I am happy to meet many nice people from the Free Software community in Chemnitz soon.

Jan Dittberner: New server, new blog, new home for portfolio.debian.net

New server The Debian Member Portfolio Service moved to a new server. This is the first service that I installed using Salt states which worked pretty well. Behind the scenes it moved from Apache httpd + mod_wsgi to nginx and uwsgi and from Debian Squeeze versions of the Python modules to the versions in Wheezy.
New blog I started this new blog using the Nikola static site and blog generator. I really like writing this way (with my favourite editor, ReSTructured Text and git) instead of using some awkward browser based GUI. I chose Nikola over other alternatives because it's Python based. I hope that I'll write a bit more often than I did in the past.

Jan Wagner: Chemnitzer Linux-Tage 2013!

Also this year the Debian project was present at Chemnitzer Linuxtage, this time right next the debianforum.de booth. The booth folks arriving on friday organized a flashmob at Expitas after booth setup. Unfortunatly our second planned flashmob at the mensa was boycotted by much more students, so we ended up in the Turm-Brauhaus, which is a great location with good drinks but the service was very harshly. On the next two days at the booth we chatted and discussed with visitors and other exhibitors a wide variety of questions, including 'When will be (the next Debian version) released?' and 'Are there installation disks available?'. The answers was as always 'When we are ready and we will have reached the quality-level we defined', 'No we don't have installation medias, as they are always outdated. Do you have an USB-dongle with you?'. Merchandising was requested by visitors as always, but we just had some leftovers of fosdem, brought by Axel. The demonstration was as usual a small box running Babelbox and xpenguins which worked out the last years too. This year there were three lectures held by Debian related people, about Debian GIS, Aptitude - known but even unknown and SSH and unreliable network connections. The organisation team did a really great job. The social event at saturday night was very exciting and we left it early in the morning. The whole event was indeed fun and a pleasure to find new friends and meet old ones of the Free Software community. Many thanks to Florian Baumann, Jan Dittberner, Andreas Tille, Christian Hoffmann, Axel Beckert, Markus Rekkenbeil, Daniel Schier, Jonas Genannt, Jan H rsch and kurio for taking care and running the booth, which worked out this year extreme smoothly from my point of view. Likewise as the last years a special thanks to TMT GmbH & Co. KG, which kindly donated additional boothtickets, the equipment, its transportation and accommodation for almost half of the booth staff.

Jan Wagner: Chemnitzer Linuxtage 2012

As announced 3 weeks ago, the Debian project was present at Chemnitzer Linuxtage. Several talks and workshops where held by people related to the Debian project. At the booth we had talks and discussions with exhibitors and visitors, unfortunately I didn t had much time to visit more than small parts of two lectures. Unfortunately (for the visitors) we didn t had any merchandising on board, while we received several requests. On Sunday Axel surprised us with some leftovers from fosdem of debian.ch merch. At the booth we had a demo machine running Babelbox and xpenguins, which attracted visitors very well. Booth Babelbox We received also more than one Just thank you by satisfied users. :) Four different talks and one workshop were held by Debian people, but they were not specific to the Debian. The workshop was about OpenStreetMap, lectures was about commandline helpers, grep everything, quality analyzing and team management in opensource projects and Conkeror and other keyboard based webbrowsers. Many thanks to Jan Dittberner, Andreas Tille, Christian Hoffmann, Florian Baumann, Christoph Egger, Axel Beckert, Adam Schmalhofer, Markus Schnalke, Sebastian Harl and Patrick Matth i for running the booth, answering a wide range of questions or just chatting with visitors . A special thank to TMT GmbH & Co. KG for providing the complete equipment and sponsoring it s transportation. At the end we have to send a big thank to the organizing team of the Chemnitzer Linuxtage. It was fun and a pleasure to find new friends and meet old ones of the Free Software community. A small sidenote was anybody aware that OpenSuSE Package search is using screenshots.debian.net?

Raphaël Hertzog: People behind Debian: Enrico Zini, member of the New Maintainer Frontdesk

Enrico ZiniEven though Enrico is not smiling on this picture, he s one of the friendliest Debian person that I know. I always enjoy his presentations because he can t refrain from inserting jokes or other funny tricks. :-) That said he s serious too, there s lots of good stuff that he has developed over the years (starting with Debtags) and he has put a lot of effort in reforming the New Maintainer process. Read on to learn more about his various projects. Raphael: Who are you? Enrico: Hi, I m Enrico Zini, a DD from Italy. I m 35 and I work as a freelance Free Software developer. One of my historical roles in Debian is taking care of Debtags, but that is not all I do: my paid work led me to write and maintain some weather forecast related software in Debian, and recently I gained a Front Desk hat, and then a DAM hat. Raphael: How did you start contributing to Debian? Enrico: It was 2001, I was at uni, I was using Debian. At some point I wanted to learn packaging so I read through the whole Policy from top to bottom. Then I thought: why package only for myself? . There were many DDs at my uni, and it only seemed natural to me to join Debian as well. Evidently this was also natural for Zack [Note from editor: Stefano Zacchiroli], who had become DD 6 months earlier and didn t hesitate to advocate me. I found the Policy and the Developer s Reference to be very interesting things to read, and I welcomed my AM s questions as an excuse to learn more. I completely understand those people who have fun trying to answer all the questions in the NM templates while they wait for an AM. With my super DAM powers I can see that my AM report was submitted on October 16, 2001 by my AM Martin Michlmayr, and that James Troup created my account 9 days later, on October 25. Raphael: You have a special interest in the New Maintainer (NM) Process since you are a Debian Account Manager (DAM) and a member of the NM Frontdesk. Thanks to your work the process is much less academic/bureaucratic than it used to be. Can you remember us the main changes? Enrico: One of the first things I noticed when I become a Front Desk member is that there was a tendency to advocate people too early, thinking by the time they ll get an AM, they ll know enough . Unfortunately, this didn t always work, and once the real NM process started it would turn into a very long and demotivating experience both for the applicant and for the AM. So we tried raising the bar on advocacies, and that seems to have helped a lot. If people join NM when they are ready, it means that NM is quick and painless both for them and their AMs, who are therefore able to process more applicants. We also did a rather radical cleanup of the NM templates , which are a repository of questions that Application Managers can ask to their applicants. We realized that AMs were just sending the whole templates to their applicants, so we moved all non-essential questions to separate files, to drastically reduce the amounts of questions that are asked by default. Other improvements in the NM process came from other parts of Debian: nowadays there are lots of ways to learn and gradually gain experience and reputation inside the project before joining NM, which means that we get many candidates who we can process quickly. For example, packages can now be uploaded via sponsors, and the Mentors project helps new contributors to find sponsors and get their first packages reviewed. Then one can now become Debian Maintainer and take full responsibility of their own packages, gaining experience and reputation. The idea of working in teams also helped: big teams like the Perl, Python, KDE, Ocaml, Haskell teams (and many more) are excellent entry points for people who have something to package. But Debian is not just for packagers, and one could join teams like the Website team, the Press and Publicity team, the Events and Merchandise team or their local translation team. Becoming DDs the non-uploading way is not just for non-technical people: one could enjoy programming but not packaging. An interesting way to get involved in that way is to help writing or maintaining some of the many Debian services. Note that I m not suggesting this as a way to learn how to program, but as a way to get involved in Debian by writing code. Finally, we started to appreciate the importance of having people activities in Debian explicitly visible, which means that the more obviously good work one has done in Debian, the less questions we need to ask. Jan Dittberner s DDPortfolio is an excellent resource for AMs and Front Desk, and I m maintaining a service called minechangelogs that for people who have done lots of work in Debian is able to fully replace the Tasks&Skills parts of the NM process. Raphael: What are your plans for Debian Wheezy? Enrico: For Wheezy I hope to be able to streamline and simplify Debtags a bit more. At Debconf11 I had a conversation with FTP-masters on how to make some tags more official, and I now have to work a bit more on that. I d also like to considerably downsize the codebase behind the debtags package, now that its job is quite clear and I don t need to experiment with fancy features the way I did in the past. I have to say that I enjoy programming more than I enjoy packaging, so most of my plans in Debian are not tied to releases. For example, I d like to finish and deploy the new NM website codebase soon: it would mean to have a codebase that s much easier to maintain, and in which it s much easier to implement new features. I d also like to design a way to allow maintainers to review the tag submission to their own packages instead of having to wait for me or David Paleino to do a regular review of all the submissions. Finally, I d like to promote the usage of apt-xapian-index in more cutting-edge packaging applications. And to design a way to maintain up to date popcon information in one s local index. And improve and promote those services that I maintain, and I tend to often have ideas for new ones. Raphael: If you could spend all your time on Debian, what would you work on? Enrico: If I could spend all my time on Debian, I would do a lot of software development: I love doing software development, but most of my development energy is spent on my paid work. I guess I would start my all your time in Debian by taking better care of the things that I m already doing, and by promoting them better so that I wouldn t end up being the only person maintaining them. After that, however, I reckon that I do have a tendency of noticing new, interesting problems in need(?) of a solution, and I guess I would end up wildly experimenting new ideas in Debian much like a victorian mad scientist. Which reminds me that I most definitely need minions! Where can I find minions? Raphael: You re the author of the Debian Community Guidelines. I have always felt that this document should be more broadly advertised. For example by integrating it in the Developer s Reference. What do you think? Enrico: The DCG was really a collection of tips to improve one s online communication, based on ideas and feedback that I collected from pestering many experienced and well-respected people for some time. Like every repository of common sense, I think it should be widely promoted but never ever turned into law. It wouldn t be a bad idea to mention it in the Developer s Reference, or to package it as a separate file in the developers-reference package. The reasons I haven t actively been pushing for that to happen are two: there isn t much in the DCG that is specific to Debian, and I don t have the resources to do a proper job maintaining it. It d be great if somebody could take over its maintenance and make it become some proper, widespread, easy-to-quote online reference document, like one of those HOWTOs that all serious people have read at some point in their lives. Raphael: What s the biggest problem of Debian? Enrico: It s sometimes hard to get feedback or help if you work on something unusual. That is partly to be expected, and partly probably due to me not having yet learnt how to get people involved in what I do. Raphael: What motivates you to continue to contribute year after year? Enrico: Debian keeps evolving, so there is always something to learn. And Debian is real, so everything I do is constantly measured against reality. What more intellectual stimulation could one possibly want? Raphael: Is there someone in Debian that you admire for their contributions? Enrico: I don t think I could reasonably list everyone I admire in Debian: pretty much in every corner of the project there is someone, sometimes not very well known, who is putting a lot of Quality in what they do. Someone who decided that X should work well in Debian or that Debian should work well for Y or that Z is something Debian people can rely on and makes sure that it is so. Those are the people who make sure Debian is and will be not just a hobby, but a base upon which I can rely for my personal and working life.
Thank you to Enrico for the time spent answering my questions. I hope you enjoyed reading his answers as I did.

Raphaël Hertzog: My Debian activities in April 2011

This is my monthly summary of my Debian related activities. If you re among the people who support my work, then you can learn how I spent your money. Otherwise it s just an interesting status update on my various projects. GNOME 3 packaging Right after the GNOME 3 release, I was eager to try it out so I helped the pkg-gnome team to update some of the packages. I did some uploads of totem, totem-pl-parser, gvfs, mutter, gnome-shell, gnome-screensaver. I also kept people informed via my blog and prepared a pinning file for adventurous users who wanted to try it out from experimental (like me). One month later, I m still using GNOME 3. There are rough edges still, but not so many. And I m starting to get used to it. Debian Rolling planning Debian Rolling is a project on my TODO list for quite some time. I decided it was time to do something about it and started a series of articles to help clarify my ideas while getting some early feedback. My goal was to prepare a somewhat polished proposal before posting it to a Debian mailing list. But as usual with Murphy s law, my plan did not work out as expected. Almost immediately after my first post the discussion started on debian-devel:
At this point it s a discussion thread of several hundreds of messages (there are several screens of messages like the one above). Many of the sub-threads have been interesting, but the general discussions mixed too many different things so that there s no clear outcome yet. Lucas Nussbaum tried to make a summary. Obviously I must adjust my plan, there s lots of feedback to process. I accepted to drive a DEP together with Sean Finney to help structure the part of the discussion that focuses on allowing development to continue during freezes. But I m also eager to fix the marketing problem of testing and have the project recognize that testing is a product in itself and that end-users should be encouraged to use it. Package Tracking System maintenance The Package Tracking System is an important tool for Debian developers, and it has been broken by some change on the Bug Tracking System. I worked around it quite quickly so that few people noticed the problem but Cron kept reminding me that I had to properly fix it. I ended up doing it last week-end. While working on the PTS, I took the opportunity to merge a patch from Jan Dittberner to enhance the news RSS feed that the PTS provides. And I also integrated information from backports.debian.org (thanks to Mehdi Dogguy for reminding me #549115). Multiarch update Not much new this month. I fixed two bugs in the multiarch dpkg branch thanks to bug reports from Ubuntu users (LP 767634, LP 756381). I m still waiting on Guillem Jover finishing his review of the multiarch branch. I m pinging him from time to time but it looks like multi-arch is no longer in his short term priority list. :-( I ve been running this code for more than 2 months and it works fine. I want to see it merged. I m ready to update my code should anything need to be changed to please Guillem. But without any feedback we re in a deadlock. Misc dpkg work While fixing a bug in update-alternatives (found in one of the valid reports on launchpad), I noticed that there was room for improvements in the error messages output by update-alternatives. I changed them to reuse the same strings that were already used in other parts of dpkg. The result is that there are a few strings less to translate (always a nice thing for the poor translators who have to deal with the thousands of strings that dpkg contains). I also tried to fix some of the most cryptic error messages in dpkg (see #621763) but that work is stalled at the request of Guillem. Book update We (me and Roland Mas) are almost done with the update of our French book for Debian Squeeze. It will hit the shelves in July or September. I m starting to prepare the fundraising campaign to make an English translation of it. We ll use ulule.com for this. On my blog I have been pleased to interview Meike Reichle, it s the first women that I have interviewed in the series but it s certainly not the last one. I also interviewed Adam D. Barratt, one of our tireless release managers. Thanks Many thanks to the people who gave me 180.35 in March and 235.37 in April. That represents 1.5 and 2 days of work for those months. See you next month for a new summary of my activities.

Jan Dittberner: Small update for the Debian Developer Portfolio Service

I just updated the software at http://ddportfolio.debian.net/ it contains some new links (UbuntuDiff, piuparts, patch tracker, search on the Debian website and with search.debian.org). Thanks to Paul Wise for the ideas. If you want to have ddportfolio.debian.net in your language you may send me translated versions of the translation template in the git repository.

Jan Dittberner: New hardware for my server at home

After some stability problems and an unresolvable PCI IRQ problem with my Debian server at home (Internet gateway, mail, PostgreSQL, LDAP and NFS server and test system), I decided to get a new mainboard and wireless card last week. I did some research to get hardware that is properly supported and where I can use the rest of my current components. I had So I had to find a mainboard with at least 2 DDR2 DIMM sockets, an AM2 compatible CPU socket in ATX format with SATA ports at least one IDE Port, a Gigabit ethernet port (serving NFS home directories) and at least 2 PCI slots (one for the wireless card) that is well supported by the current Debian Squeeze Linux kernel. As I had some issues with the previous board's nvidia SATA chipset I wanted to get something else that is AHCI compatible. After some research I decided to buy a Gigabyte GA-MA74GM-S2H (rev. 3.0) which is available for a good price and fits all my criteria (2 DDR2 DIMM slots, 6 SATA ports, an RTL8169 based Gigabit ethernet ports, 2 PCI slots, ...). The mainboard uses an AMD 740G + SB710 Chipset. It has an integrated graphics chipset which I don't really need because I run the machine as a headless system. As I use the server as a wireless access point I need a wireless network adapter that supports AP mode. There are not many chipsets that are properly supported in AP mode and allow good data rates so I decided to get an Atheros ath9k based card, because I don't need non-free firmware like with broadcom based cards and could find some affordable hardware. The previous was a Netgear WG311 ath5k card that had issues that it lost its connection under more than minimum load and could only be reanimated by a system reboot. I looked at the Linux Wireless pages and found out that D-Link has a matching adapter the DWL-G520. Unfortunatelly they don't tell about the used chipset (as almost all other vendors too) and write about possibly changing hardware at the product sheet. To be sure I looked at their Windows driver's .inf files and found nothing indicating that there are any non Atheros variants of the card. I also ordered two Fantec MR-35 SATA mobile racks for more comfort when one of the RAID1 discs crashes (had 2 crashes last year) and a 12" chassis fan to keep the system cool. Today the package arrived and after unpacking and putting everything together I started the system (with keyboard and a display attached) to see how it works. All hardware was automatically detected by the current Debian Squeeze system and I only had to remove the entries for the old onboard network adapter and the old wireless adapter from /etc/udev/rules.d/70-persistent-net.rules and fix the device names for the new network cards. I added a new stanza for the Intel ethernet adapter in /etc/network/interfaces and setup a set of ferm rules to have a working firewall (thanks to Formorer for the suggestion to use ferm). After this was finished everything worked fine so far and I put the machine at its normal place without keyboard and display. To verify that the stability situation had really improved, I copied some huge files over the network (both wired and wireless and in both
directions). Afterwards I did a bonnie++ benchmark to test the SATA and hard drive reliability. Everything went well and I'm happy with my investment.
