Lunar: Reproducible builds: week 17 in Stretch cycle

A good amount of the Debian reproducible builds team had the chance to enjoy face-to-face interactions during DebConf15.
Names in red and blue were all present at DebConf15
Picture of the  reproducible builds  talk during DebConf15
Hugging people with whom one has been working tirelessly for months gives a lot of warm-fuzzy feelings. Several recorded and hallway discussions paved the way to solve the remaining issues to get reproducible builds part of Debian proper. Both talks from the Debian Project Leader and the release team mentioned the effort as important for the future of Debian. A forty-five minutes talk presented the state of the reproducible builds effort. It was then followed by an hour long roundtable to discuss current blockers regarding dpkg, .buildinfo and their integration in the archive. Picture of the  reproducible builds  roundtable during DebConf15 Toolchain fixes Reiner Herrmann submitted a patch to make rdfind sort the processed files before doing any operation. Chris Lamb proposed a new patch for wheel implementing support for SOURCE_DATE_EPOCH instead of the custom WHEEL_FORCE_TIMESTAMP. akira sent one making man2html SOURCE_DATE_EPOCH aware. St phane Glondu reported that dpkg-source would not respect tarball permissions when unpacking under a umask of 002. After hours of iterative testing during the DebConf workshop, Sandro Knau created a test case showing how pdflatex output can be non-deterministic with some PNG files. Packages fixed The following 65 packages became reproducible due to changes in their build dependencies: alacarte, arbtt, bullet, ccfits, commons-daemon, crack-attack, d-conf, ejabberd-contrib, erlang-bear, erlang-cherly, erlang-cowlib, erlang-folsom, erlang-goldrush, erlang-ibrowse, erlang-jiffy, erlang-lager, erlang-lhttpc, erlang-meck, erlang-p1-cache-tab, erlang-p1-iconv, erlang-p1-logger, erlang-p1-mysql, erlang-p1-pam, erlang-p1-pgsql, erlang-p1-sip, erlang-p1-stringprep, erlang-p1-stun, erlang-p1-tls, erlang-p1-utils, erlang-p1-xml, erlang-p1-yaml, erlang-p1-zlib, erlang-ranch, erlang-redis-client, erlang-uuid, freecontact, givaro, glade, gnome-shell, gupnp, gvfs, htseq, jags, jana, knot, libconfig, libkolab, libmatio, libvsqlitepp, mpmath, octave-zenity, openigtlink, paman, pisa, pynifti, qof, ruby-blankslate, ruby-xml-simple, timingframework, trace-cmd, tsung, wings3d, xdg-user-dirs, xz-utils, zpspell. The following packages became reproducible after getting fixed: Uploads that might have fixed reproducibility issues: Some uploads fixed some reproducibility issues but not all of them: Patches submitted which have not made their way to the archive yet: St phane Glondu reported two issues regarding embedded build date in omake and cduce. Aur lien Jarno submitted a fix for the breakage of make-dfsg test suite. As binutils now creates deterministic libraries by default, Aur lien's patch makes use of a wrapper to give the U flag to ar. Reiner Herrmann reported an issue with pound which embeds random dhparams in its code during the build. Better solutions are yet to be found. Package pages on now have a new layout improving readability designed by Mattia Rizzolo, h01ger, and Ulrike. The navigation is now on the left as vertical space is more valuable nowadays. armhf is now enabled on all pages except the dashboard. Actual tests on armhf are expected to start shortly. (Mattia Rizzolo, h01ger) The limit on how many packages people can schedule using the reschedule script on Alioth has been bumped to 200. (h01ger) mod_rewrite is now used instead of JavaScript for the form in the dashboard. (h01ger) Following the rename of the software, debbindiff has mostly been replaced by either diffoscope or differences in generated HTML and IRC notification output. Connections to UDD have been made more robust. (Mattia Rizzolo) diffoscope development diffoscope version 31 was released on August 21st. This version improves fuzzy-matching by using the tlsh algorithm instead of ssdeep. New command line options are available: --max-diff-input-lines and --max-diff-block-lines to override limits on diff input and output (Reiner Herrmann), --debugger to dump the user into pdb in case of crashes (Mattia Rizzolo). jar archives should now be detected properly (Reiner Herrman). Several general code cleanups were also done by Chris Lamb. strip-nondeterminism development Andrew Ayer released strip-nondeterminism version 0.010-1. Java properties file in jar should now be detected more accurately. A missing dependency spotted by St phane Glondu has been added. Testing directory ordering issues: disorderfs During the reproducible builds workshop at DebConf, participants identified that we were still short of a good way to test variations on filesystem behaviors (e.g. file ordering or disk usage). Andrew Ayer took a couple of hours to create disorderfs. Based on FUSE, disorderfs in an overlay filesystem that will mount the content of a directory at another location. For this first version, it will make the order in which files appear in a directory random. Documentation update Dhole documented how to implement support for SOURCE_DATE_EPOCH in Python, bash, Makefiles, CMake, and C. Chris Lamb started to convert the wiki page describing SOURCE_DATE_EPOCH into a Freedesktop-like specification in the hope that it will convince more upstream to adopt it. Package reviews 44 reviews have been removed, 192 added and 77 updated this week. New issues identified this week: locale_dependent_order_in_devlibs_depends, randomness_in_ocaml_startup_files, randomness_in_ocaml_packed_libraries, randomness_in_ocaml_custom_executables, undeterministic_symlinking_by_rdfind, random_build_path_by_golang_compiler, and images_in_pdf_generated_by_latex. 117 new FTBFS bugs have been reported by Chris Lamb, Chris West (Faux), and Niko Tyni. Misc. Some reproducibility issues might face us very late. Chris Lamb noticed that the test suite for python-pykmip was now failing because its test certificates have expired. Let's hope no packages are hiding a certificate valid for 10 years somewhere in their source! Pictures courtesy and copyright of Debian's own paparazzi: Aigars Mahinovs.

Lunar: Reproducible builds: week 16 in Stretch cycle

What happened in the reproducible builds effort this week: Toolchain fixes Valentin Lorentz sent a patch for ispell to initialize memory structures before dumping their content. In our experimental repository, qt4-x11 has been rebased on the latest version (Dhole), as was doxygen (akira). Packages fixed The following packages became reproducible due to changes in their build dependencies: backup-manager, cheese, coinor-csdp, coinor-dylp, ebook-speaker, freefem, indent, libjbcrypt-java, qtquick1-opensource-src, ruby-coffee-script, ruby-distribution, schroot, twittering-mode. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues but not all of them: Patches submitted which have not made their way to the archive yet: akira found another embedded code copy of texi2html in maxima. Work on testing several architectures has continued. (Mattia/h01ger) Package reviews 29 reviews have been removed, 187 added and 34 updated this week. 172 new FTBFS reports were filled, 137 solely by Chris West (Faux). josch spent time investigating the issue with fonts in PDF files. Chris Lamb documented the issue affecting documentation generated by ocamldoc. Misc. Lunar presented a general Reproducible builds HOWTO talk at the Chaos Communication Camp 2015 in Germany on August 13th. Recordings are already available, as well as slides and script. h01ger and Lunar also used CCCamp15 as an opportunity to have discussions with members of several different projects about reproducible builds. Good news should be coming soon.

Paul Wise: Another year, another log entry

It has been almost a full year since my last log entry. It has been a busy work year, I attended some nice conferences and did minimal FLOSS stuff. On the work side of things I was a third of an Australian VoIP startup that came and went. I setup Debian servers, installed OpenSIPS and associated software, wrote OpenSIPS scripts, wrote peripheral software and did customer support. We had a good thing going there for a while, some fans on the Whirlpool forums but in the end there wasn't enough money for the requisite marketing and local market circumstances were squeezing Australian VoIP providers anyway. On the conference side of things I went to LCA 2010, the Thai Mini-DebCamp 2010, DebConf10 and FOSSASIA 2010. Had a great time at all of them. At LCA 2010 in windy Wellington, New Zealand the distributions summit organised by Martin Krafft was one of the highlights. It was dominated by Debian/Ubuntu talks but there were some other interesting ones, especially the one on GoboLinux's integration of domain-specific package managers. Also excellent were the keynotes given by Gabriella Coleman (Best & worst of times), Mako Hill (Antifeatures) and others, which I felt gave LCA an improved and very welcome focus on software freedom. There were quite a few Debian folks at LCA, it was great to hang out with them during the week and afterwards. Monopedal sumo with mako and others was hilarious fun. At the Thailand Mini-DebCamp 2010 in Khon Kaen, I was glad to see Andrew Lee (Taiwan) and Christian Perrier (France) again and meet Yukiharu YABUKI (Japan) and Daiki Ueno (Japan). In addition to the five international folks, there were quite a few locals, including Thailand's currently sole Debian member, Theppitak Karoonboonyanan. The event was hosted at Khon Kaen University and opened with my talk about the Debian Social Contract and the Debian Free Software Guidelines. This was followed by a number of talks about Debian package building, a 3-day BSP where we touched 57 bugs, a great day of sightseeing and talks about i18n, derivative distros, keysigning, mirrors, contribution and a discussion about DebConf. During the week there was also the usual beersigning, combined with eating of unfamiliar and "interesting" Thai snacks. After the conference Andrew and I roamed some markets in Bangkok and got Thai massages. Beforehand I also visited a friend from my travels on the RV Heraclitus in Chiang Mai, once again experiencing the awesomeness of trains in Asia, unfortunately during the dry season this time. I took a lot of photos during my time in Thailand and ate a lot of great and spicy food. As a vegetarian I especially appreciated the organiser's efforts to accommodate this during the conference. At DebConf10 in New York City, by far the highlight was Eben Moglen's vision of the FreedomBox. Negotiating the hot rickety subways was fun, the party at the NYC Resistor space was most excellent, Coney Island was hot and the water a bit yuck, zack threw a ball, the food and campus was really nice. Really enjoyed the lintian BoF, ARM discussions, shy folks, GPLv3 question time, paulproteus' comments & insights, wiki BoF, puppet BoF, derivatives BoF, Sita, astronomy rooftop, cheese, virt BoF, Libravatar, DebConf11, Brave new Multimedia World, bagels for breakfast, CUT, OpenStreetMap & lightning talks. Having my power supply die was not fun at all. Afterwards I hung out with a couple of the exhausted organisers, ate awesome vegan food and fell asleep watching a movie about dreams. One weird thing about DebConf10 was that relatively few folks used the DebConf gallery to host their photos, months later only myself and Aigars Mahinovs posted any photos there. At FOSSASIA 2010 in H Ch Minh City (HCMC) was a mini-DebConf. I arrived at the HCMC airport and was greeted by Huyen (thanks!!), one of FOSSASIA's numerous volunteers, who bundled me into a taxi bound for the speakers accommodation and pre-event meetup at The Spotted Cow Bar. The next day the conference opened at the Raffles International College and after looking at the schedule I noticed that I was to give a talk about Debian that day. Since I didn't volunteer for such a talk and had nothing prepared, the schedule took me by surprise. So shortly after an awesome lunch of Vietnamese pancakes we gathered some Debian folks and a random Fedora dude and prepared a short intro to Debian. The rest of the day the highlights were the intro, video greetings and the fonts, YaCy and HTML5 talks. The next day the Debian MiniConf began with Arne Goetje and everyone trying to get Debian Live LXDE USB keys booted on as many machines in the classroom as possible (many didn't boot). Once people started showing up we kicked off with Thomas Goirand's introduction to the breadth of Debian. Others talked about Debian pure blends, Gnuk and building community and packages. The second last session was about showing the Vietnamese folks in the room how to do l10n and translation since Debian had only one Vietnamese translator (Clytie Siddall). After manually switching keyboard layouts (seems LXDE doesn't have a GUI for that) on the English LXDE installs, the two Cambodian folks were able to do some Khmer translation too. This was a great session and it resulted in two extra Vietnamese translators joining Debian. It went over time so I didn't end up doing my presentation about package reviewing. We rushed off to a university where the random Fedora ch^Wambassador was hosting a Fedora 14 release party in a huge packed classroom. There were a lot of excited faces, interesting and advanced questions and it was in general a success. Afterwards we had some food, joined up with some other speakers and ended up in a bar in the gross tourist zone. On the final day we hung around in the Debian room, went downstairs for the group photo and final goodbyes. Later we found a place with baked goods, coffee and juices and navigated the crazy traffic to a nice local restaurant. The next morning Arne & I went to the airport, others went on a Mekong Delta tour and Jonas hung out with the organisers. I took less photos than at other events but got a few interesting ones. I avoided doing a lot of FLOSS stuff over the last year, I hope to work on some things in the coming months; I'm also planning some interesting travel and acquiring some new technological goods, more on those in some later posts.

Christian Perrier: Amazing week in Khon Kaen for Thailand MiniDebconf

I'm now on my way back from The first miniDebCamp and miniDebconf that happened from March 13th to March 19th in Khon Kaen, Thailand. This even was organized locally by a team of very motivated Thai Debian enthusiasts and contributors, such as Theppitak Karoonboonyanan (*the* Thai DD), Neutron Soutmun, Kitt Tientanopajai, and all those whose name I'm not remembering as of now (I hope they won't mind). The even had kinda the structure of DebConfs, with a few days of "Debcamp" to begin. See the full schedule. We were hosted in Khon Kaen University (KKU), one one the most famous universities in Thailand, a small "town in town" in a city with a few hundred thousand inhabitants (dunno exactly). Lodging was done in a hotel located inside the university. Interestingly, the hotel was also hosting youg students participating to "Summer Camps" (apparently training systems to get good school results) gving to all this a very young atmosphere. The hacking lab and talks location was a 30-seat room in the university library, and meals were brought in there very efficiently, with the very specific way that Thai people have to transport each and every kind of meal (in small plastic bags closed by rubber). I arrived only in the 3rd day because I had commitments at home that made it impossible to me to come for the first day. During these days, people have been very busy hacking and participating to the Bug Squashing Party. During that BSP, about 50 bugs have been touched, without about 15 or so closed. Other non Thai attendees were Andrew Lee from TW, Paul Wise from AU, Daiki Ueno and Yukiharu Yabuki from JP. Organizers were expecting some attendees from neighbouring countries such as Laos, Vietnam or Cambodia. Unfortunately, none of them could come, including Anousak Soupavanh, leader of Lao free software localization efforts, who I was very impatient to meet. Transport difficulties, or visa problems, do not make things easy in that part of the world. On Wednesday we had a "DayTrip" as it is common for such event. We went abotu 50 km away from Khon Kaen, to visit a nice place, close to a dam lake, and climbed a hill surrounded by a big temple and a giant Buddha statue. Then we had a wonderful lunch in a fish restaurant in the very specific Thai way to share stuff: everything is on the table and you pick your food here and there, at you rconvenience. Of course, local advice before trying apparently innocent food is always worth it because the fire might be hidden anywhere (for instance in that soja plate which I tried and that set my mouth as a burning hell for 20 minutes). The journey ended by a visit of a great temple in Khon Kaen and, very noticeably by a dinner in a very popular barbecue restaurant in "all you can eat" style for...100Bath (so, about 2.5 euros). Maybe only vegetarian people had more trouble enjoying the meal as it was mostly made of various meat (and sea food). The talk days were very intense, at least in my opinion. Probably because I ended up giving four talks, some of them completely improvised (about IP-over-DNS, which I was using at the hotel and about which many wanted to learn a little bit more, and GPG keysigning processes). It turned out that the GPG talk was well received and, discussing with Paul later on, we agreed that such a talk, mostly meant to explain the DOs and DON'Ts For good GPG keys signing, could be a good idea even for Debconfs. There were also a few talks about local initiatives and efforts to develop (and not only promote) free software. We have no recordings of these talks as we were infortunately missing some video recording installation (maybe next time, Thep) just like the miniConf that was happening in Panama at about the same time was having. Due to local regulation on the university network, we had some limitations with Internet access (some firewalling that for instance was preventing SIP to work properly, which made a video-conference with a japanese user group fail, unfurtunately). The event ended in a round table discussion about ideas to organize something bigger in the future. The local community in Thailand has apparently the energy, maybe ressources and local support to be able to organize a slightly bigger event as first try (somethign like an Asian DebConf or something similar, targeting mostly Asian contributors and about 50-100 people. Thailand seems to be a good target to host such event, with many things being relatively inexpensive (and not only beer!). And they even think about possibly hosting a Debconf at some time in the future (actually, Martin Krafft should also be credited for bringing this idea). That isn't as crazy as it seems and, provided that potential organizers start involving themselves in the current Debconfs, everything seems to be possible. After all, if we look back to 2005, only one person (hello, Safir) was seriously thinking that Debconf could really happen in Bosnia and Herzegovina, right? After this week (followed by 2.5 days of sightseeing in Bangkok for me, plus a small meeting today with local Thai Linux corporate users and IT company owners), I feel like the mood in Asia about Debian development is high and full of potential. The miniconf last year in Taiwan was already a good success, by establishing a good connection between people.....we need to keep that alive and, hopefully, there will be other miniconfs in this part of the world. And, well, if I can be there, I'll be there.

Kenshi Muto: Preparation for Japan Debian Mini Conf 2005

Yukiharu Yabuki <yabuki at> announced Japan Debian Mini Conf 2005 at some computer mailing lists. I have a session on 28th to talk about overview of Debian GNU/Linux Sarge and Debian Project as 'Welcome to the Debian world, Get ready!' Your well-known people tbm, Ukai, Gotom, and Junichi have a session also. Web page doesn't say well, but Yabuki is trying to assign translator to translate Japanese to English. Furthermore I'm a coordinator of key sign party at this conference. If you'd like to participate, please see KeySignParty.html.en and send your public key of GnuPG to me. We'll do assurance party at there also. ... Now I'm freezing in front of Impress :)
