Raphaël Hertzog: My Free Software Activities in February and March 2016

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. I skipped my monthly report last time so this one will cover two months. I will try to list only the most important things to not make it too long.  The Debian Handbook I worked with Ryuunosuke Ayanokouzi to prepare a paperback version of the Japanese translation of my book. Thanks to the efforts of everybody, it s now available. Unfortunately, Lulu declined to take it in distribution program so it won t be available on traditional bookstores (like Amazon, etc.). The reason is that they do not support non-latin character sets in the meta-data. I tried to cheat a little bit by inputting the description in English (still explaining that the book was in Japanese) but they rejected it nevertheless because the English title could mislead people. So the paperback is only available on lulu.com. Fortunately, the shipping costs are reasonable if you pick the most economic offer. Following this I invited the Italian, Spanish and Brazilian Portuguese translators to complete the work (they were close will all the strings already translated, mainly missing translated screenshots and some backcover content) so that we can also release paperback versions in those languages. It s getting close to completion for them. Hopefully we will have those available until next month. Distro Tracker In early February, I tweaked the configuration to send (by email) exceptions generated by incoming mails and by routine task. Before this they were logged but I did not take the time to look into them. This quickly brought a few issues into light and I fixed them as they appeared: for instance the bounce handling code was getting confused when the character case was not respected, and it appears that some emails come back to us after having been lowercased. Also the code was broken when the References field used more than one line on incoming control emails. This brought into light a whole class of problems with the database storing twice the same email with only differing case. So I did further work to merge all those duplicate entries behind a single email entry. Later, the experimental Sources files changed and I had to tweak the code to work with the removal of the Files field (relying instead on Checksums-* to find out the various files part of the entry). At some point, I also fixed the login form to not generate an exception when the user submits an empty form. I also decided that I no longer wanted to support Django 1.7 in distro tracker as Django 1.8 is the current LTS version. I asked the Debian system administrators to update the package on tracker.debian.org with the version in jessie-backports. This allowed me to fix a few deprecation warnings that I kept triggering because I wanted the code to work with Django 1.7. One of those warnings was generated by django-jsonfield though and I could not fix it immediately. Instead I prepared a pull request that I submitted to the upstream author. Oh, and a last thing, I tweaked the CSS to densify the layout on the package page. This was one of the most requested changes from the people who were still preferring packages.qa.debian.org over tracker.debian.org. Kali and new pkg-security team As part of my Kali work, I have been fixing RC bugs in Debian packages that we use in Kali. But in many cases, I stumbled upon packages whose maintainers were really missing in action (MIA). Up to now, we were only doing non-maintainers upload (NMU) but I want to be able to maintain those packages more effectively so we created a new pkg-security team (we re only two right now and we have no documentation yet, but if you want to join, you re welcome, in particular if you maintain a package which is useful in the security field). arm64 work. The first 3 packages that we took over (ssldump, sucrack, xprobe) are actually packages that were missing arm64 builds. We just started our arm64 port on Kali and we fixed them for that architecture. Since they were no longer properly maintained, in most cases it was just a matter of using dh_autoreconf to get up-to-date config. sub,guess files. We still miss a few packages on arm64: vboot-utils (that we will likely take over soon since it s offered for adoption), ruby-libv8 and ruby-therubyracer, ntopng (we have to wait a new luajit which is only in experimental right now). We also noticed that dh-make-golang was not available on arm64, after some discussion on #debian-buildd, I filed two bugs for this: #819472 on dh-make-golang and #819473 on dh-golang. RC bug fixing. hdparm was affected by multiple RC bugs and the release managers were trying to get rid of it from testing. This removed multiple packages that were used by Kali and its users. So I investigated the situation of that package, convinced the current maintainers to orphan it, asked for new maintainers on debian-devel, reviewed multiple updates prepared by the new volunteers and sponsored their work. Now hdparm is again RC-bug free and has the latest upstream version. We also updated jsonpickle to 0.9.3-1 to fix RC bug #812114 (that I forwarded upstream first). Systemd presets support in init-system-helpers. I tried to find someone (to hire) to implement the system preset feature I requested in #772555 but I failed. Still Andreas Henriksson was kind enough to give it a try and sent a first patch. I tried it and found some issues so I continued to improve it and simplify it I submitted an updated patch and pinged Martin Pitt. He pointed me to the DEP-8 test failures that my patch was creating. I quickly fixed those afterwards. This patch is in use in Kali and lets us disable network services by default. I would like to see it merged in Debian so that everybody can setup systemd preset file and have their desire respected at installation time. Misc bug reports. I filed #813801 to request a new upstream release of kismet. Same for masscan in #816644 and for wkhtmltopdf in #816714. We packaged (before Debian) a new upstream release of ruby-msgpack and found out that it was not building on armel/armhf so we filed two upstream tickets (with a suggested fix). In #814805, we asked the pyscard maintainer to reinstate python-pyscard that was dropped (keeping only the Python3 version) as we use the Python 2 version in Kali. And there s more: I filed #816553 (segfault) and #816554 against cdebootstrap. I asked for dh-python to have a better behaviour after having being bitten by the fact that dh with python3 was not doing what I expected it to do (see #818175). And I reported #818907 against live-build since it is failing to handle a package whose name contains an upper case character (it s not policy compliant but dpkg supports them). Misc packaging I uploaded Django 1.9.2 to unstable and 1.8.9 to jessie-backports. I provided the supplementary information that Julien Cristau asked me in #807654 but despite this, this jessie update has been ignored for the second point release in a row. It is now outdated until I update it to include the security fixes that have been released in the mean time but I m not yet sure that I will do it the lack of cooperation of the release team for that kind of request is discouraging. I sponsored multiple uploads of dolibarr (on security update notably) and tcpdf (to fix one RC bug). Thanks See you next month for a new summary of my activities.

Andreas Metzler: How to put on one's hardboots, when ligaments are damaged

I have finally managed to do (a little bit of) snowboarding again this weekend. Previously I had failed early, when trying to pull on my hard-boots. I had (partially) torn some ligament in the ankle joint in February and am generally fine now, but exactly this movement still caused pain. What worked was to
  1. take the liner out of the boot,
  2. pull on the liner,
  3. step into the outer shell.

Tassia Camoes Araujo: Some impressions of a flourishing community bits from the MiniDebConf Curitiba @ Montreal

Last month I more-or-less accepted an invitation that got me scared at first, panicking after a while. Why do I put myself in such an uncomfortable position? Well, I think that s how we grow up ;-) I was first contacted to talk about women participation in Debian, which I kindly refused, but I said I would maybe talk about motivating new contributors, possibly with some more friends that would maybe join me at the stage. I need to confess that at that moment I had no idea (ok, a vague idea ) about what I was going to talk. So I promptly emailed some Debian friends, shared the invitation, shared some thoughts, got feedbacks, got encouragement, and we finally made it! talk_transmission For the video conference we used mconf.org which worked super well (the downside is that it requires flash, maybe you could help them get rid of it?). I had also recorded a backup video with vokoscreen, just in case Murphy would decide to go to Curitiba but everything worked well. We a single moment with connection issues, but the torrent user kindly released the bandwidth The main point I made in the talk is that Debian as a Universal Operating System is still an utopia, especially when we extend our understanding of universality to our contributors. And as an utopia, it serves to make us walk! The more we advance, the more it gets further away, so we need to keep walking. Another important point was that diversity is not an issue that touches only woman. My audience was full of Portuguese native speakers, from a third world country, a few women, many more man, a couple of DDs, some longtime contributors, some newbies, and most of them are also part of minorities in our community. I bet many of them has already felt like a weed growing surrounded by concrete at least once in their lifetimes Solidarity towards our utopia was my final message. Just for fun, and to make a recap of our conversation at the end, I made a list of 10 steps that we could all give to contribute to a more universal Debian: 1. Read our Social Contract and make sure we are all at the same page
2. Improve Debian documentation
3. Remember that diversity does not concern only women
4. Keep an eye on minority groups and show solidarity
5. Be open and alert to the needs of newbies
6. Help Debian teams to be prepared to welcome new contributors
7. Reserve part of our time to integrate new members to the community
8. Promote hands-on meetings (local and remote)
9. Promote peer-mentoring among newbie contributors
10. Do not see Debian members as special beings, we are all humans! You can check my slides or the video of the live transmission if you want to see more. In case you can not follow the audio, I d be happy to provide subtitles (but I probably won t work on that if I don t receive have any request). And if you invite me to another conference, we can have a similar chat at with your community. Note: in person is more fun ;-) Finally, I d like to thank the participants of the mini-DebConf, those that followed this session and those who were practicing how to package on the other room, Paulo Santana and all the local organization team for the invitation, Ana Guerrero and Laura Arjona for the remote support and feedback, Andreas Tille for the efforts in integrating new contributors, Christian Perrier for the developer statistics, Val ssio for being in the audience and the Debian Project for the inspiration. What we had we Brazil this weekend was a taste of a flourishing and welcoming community, I am proud and honored to be part of it!

Joachim Breitner: GHC performance is rather stable

Johannes Bechberger, while working on his Bachelor s thesis supervised by my colleague Andreas Zwinkau, has developed a performance benchmark runner and results visualizer called temci , and used GHC as a guinea pig. You can read his elaborate analysis on his blog. This is particularly interesting given recent discussions about GHC itself becoming slower and slower, as for example observed by Johannes Waldmann and Anthony Cowley. Johannes Bechberger s take-away is that, at least for the programs at hand (which were taken from the The Computer Language Benchmarks Game, there are hardly any changes worth mentioning, as most of the observed effects are less than a standard deviation and hence insignificant. He tries hard to distill some useful conclusions from the data; the one he finds are: If you are interested, please head over to Johannes s post and look at the gory details of the analysis and give him feedback on that. Also, maybe his tool temci is something you want to try out? Personally, I find it dissatisfying to learn so little from so much work, but as he writes: It s so easy to lie with statistics. , and I might add lie to yourself , e.g. by ignoring good advise about standard deviations and significance. I m sure my tool gipeda (which powers perf.haskell.org) is guilty of that sin. Maybe a different selection of test programs would yield more insight; the benchmark s games programs are too small and hand-optimized, the nofib programs are plain old and the fibon collection has bitrotted. I would love to see a curated, collection of real-world programs, bundled with all dependencies and frozen to allow meaningful comparisons, but updated to a new, clearly marked revision, on a maybe bi-yearly basis maybe Haskell-SPEC-2016 if that were not a trademark infringement.

Daniel Pocock: Comments about people with mental illness

A quote:
As the Buddha said 2500 years ago... we're all out of our fucking minds. (Albert Ellis)
There have been a few occasions over the last year where people suffering mental illnesses have been the subject of much discussion. In March 2015 there was the tragic loss of Germanwings flight 9525. It was discovered that the co-pilot, Andreas Lubitz, had been receiving treatment for mental illness. Under strict privacy laws, nobody at his employer, the airline, had received any information about the diagnosis or treatment. During the summer, the private mailing list for a large online community discussed the mental illness of a contributor to a project. Various people expressed opinions that appeared to be generalizations about all those with mental illness. Some people hinted the illness was a lie to avoid work while others speculated about options for treatment. Nobody involved mentioned having any medical expertise. It is ironic that on the one hand, we have the dramatic example of an aircraft crashing at the hands of somebody who is declared unfit to work but working anyway and on the other hand when somebody else couldn't do something, the diagnosis is being disputed by people who find it inconvenient or don't understand it. More recently, there has been openly public discussion about whether another developer may have had mental illness. Once again, there doesn't appear to be any evidence from people with any medical expertise or documentation whatsoever. Some of the comments appear to be in the context of a grudge or justifying some other opinion. What's worse, some comments appear to suggest that mental illness can be blamed for anything else that goes wrong in somebody's life. If somebody is shot and bleeds to death, do you say low blood pressure killed him or do you just say he was shot? Likewise, if somebody is subject to some kind of bullying and abused, does this have no interaction with mental illness? In fact, Google reveals an enormous number of papers from experts in this field suggesting that mental illness can arise or be exacerbated by bad experiences. Although it may not have been clear at that point in time, when we look back at Alan Turing's death today, suicide was not a valid verdict and persecution was a factor. Statistics tell us that 1 in 4 people experience a mental health problem in the UK each year. In the USA it is 26% of the adult population, each year. These may be long term conditions or they may be short term conditions. They may arise spontaneously or they may be arising from some kind of trauma, abuse or harassment in the home, workplace or some other context. For large online communities, these statistics imply it is inevitable that some participants will be suffering from mental illness and others will have spouses, parents or children suffering from such conditions. These people will be acutely aware of the comments being made publicly about other people in the community. Social interaction also relates to the experience of mental illness, people who are supported by their community and society are more likely to recover while those who feel they are not understood or discriminated against may feel more isolated, compounding their condition. As a developer, I wouldn't really like the idea of doctors meddling with my code, so why is it that some people in the IT and business community are so happy to meddle around in the domain of doctors, giving such strong opinions about something they have no expertise in? Despite the tragic loss of life in Germanwings 9525, observing some of these other discussions that have taken place reminds me why Germany and some other countries do have such strict privacy laws for people who seek medical treatment.

Lunar: Reproducible builds: week 36 in Stretch cycle

What happened in the reproducible builds effort between December 27th and January 2nd: Infrastructure dak now silently accepts and discards .buildinfo files (commit 1, 2), thanks to Niels Thykier and Ansgar Burchardt. This was later confirmed as working by Mattia Rizzolo. Packages fixed The following packages have become reproducible due to changes in their build dependencies: banshee-community-extensions, javamail, mono-debugger-libs, python-avro. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues, but not all of them: Untested changes: reproducible.debian.net The testing distribution (the upcoming stretch) is now tested on armhf. (h01ger) Four new armhf build nodes provided by Vagrant Cascandian were integrated in the infrastructer. This allowed for 9 new armhf builder jobs. (h01ger) The RPM-based build system, koji, is now in unstable and testing. (Marek Marczykowski-G recki, Ximin Luo). Package reviews 131 reviews have been removed, 71 added and 53 updated in the previous week. 58 new FTBFS reports were made by Chris Lamb and Chris West. New issues identified this week: nondeterminstic_ordering_in_gsettings_glib_enums_xml, nondeterminstic_output_in_warnings_generated_by_breathe, qt_translate_noop_nondeterminstic_ordering. Misc. Steven Chamberlain explained in length why reproducible cross-building across architectures mattered, and posted results of his tests comparing a stage1 debootstrapped chroot of linux-i386 once done from official Debian packages, the others cross-built from kfreebsd-amd64.

Lunar: Reproducible builds: week 35 in Stretch cycle

What happened in the reproducible builds effort between December 20th to December 26th: Toolchain fixes Mattia Rizzolo rebased our experimental versions of debhelper (twice!) and dpkg on top of the latest releases. Reiner Herrmann submited a patch for mozilla-devscripts to sort the file list in generated preferences.js files. To be able to lift the restriction that packages must be built in the same path, translation support for the __FILE__ C pre-processor macro would also be required. Joerg Sonnenberger submitted a patch back in 2010 that would still be useful today. Chris Lamb started work on providing a deterministic mode for debootstrap. Packages fixed The following packages have become reproducible due to changes in their build dependencies: bouncycastle, cairo-dock-plug-ins, darktable, gshare, libgpod, pafy, ruby-redis-namespace, ruby-rouge, sparkleshare. 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: reproducible.debian.net Statistics for package sets are now visible for the armhf architecture. (h01ger) The second build now has a longer timeout (18 hours) than the first build (12 hours). This should prevent wasting resources when a machine is loaded. (h01ger) Builds of Arch Linux packages are now done using a tmpfs. (h01ger) 200 GiB have been added to jenkins.debian.net (thanks to ProfitBricks!) to make room for new jobs. The current count is at 962 and growing! diffoscope development Aside from some minor bugs that have been fixed, a one-line change made huge memory (and time) savings as the output of transformation tool is now streamed line by line instead of loaded entirely in memory at once. disorderfs development Andrew Ayer released disorderfs version 0.4.2-1 on December 22th. It fixes a memory corruption error when processing command line arguments that could cause command line options to be ignored. Documentation update Many small improvements for the documentation on reproducible-builds.org sent by Georg Koppen were merged. Package reviews 666 (!) reviews have been removed, 189 added and 162 updated in the previous week. 151 new fail to build from source reports have been made by Chris West, Chris Lamb, Mattia Rizzolo, and Niko Tyni. New issues identified: unsorted_filelist_in_xul_ext_preferences, nondeterminstic_output_generated_by_moarvm. Misc. Steven Chamberlain drew our attention to one analysis of the Juniper ScreenOS Authentication Backdoor: Whilst this may have been added in source code, it was well-disguised in the disassembly and just 7 instructions long. I thought this was a good example of the current state-of-the-art, and why we'd like our binaries and eventually, installer and VM images reproducible IMHO. Joanna Rutkowska has mentioned possible ways for Qubes to become reproducible on their development mailing-list.

Lunar: Reproducible builds: week 34 in Stretch cycle

What happened in the reproducible builds effort between December 13th to December 19th: Infrastructure Niels Thykier started implementing support for .buildinfo files in dak. A very preliminary commit was made by Ansgar Burchardt to prevent .buildinfo files from being removed from the upload queue. Toolchain fixes Mattia Rizzolo rebased our experimental debhelper with the changes from the latest upload. New fixes have been merged by OCaml upstream. Packages fixed The following 39 packages have become reproducible due to changes in their build dependencies: apache-mime4j, avahi-sharp, blam, bless, cecil-flowanalysis, cecil, coco-cs, cowbell, cppformat, dbus-sharp-glib, dbus-sharp, gdcm, gnome-keyring-sharp, gudev-sharp-1.0, jackson-annotations, jackson-core, jboss-classfilewriter, jboss-jdeparser2, jetty8, json-spirit, lat, leveldb-sharp, libdecentxml-java, libjavaewah-java, libkarma, mono.reflection, monobristol, nuget, pinta, snakeyaml, taglib-sharp, tangerine, themonospot, tomboy-latex, widemargin, wordpress, xsddiagram, xsp, zeitgeist-sharp. 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: reproducible.debian.net Packages in experimental are now tested on armhf. (h01ger) Arch Linux packages in the multilib and community repositories (4,000 more source packages) are also being tested. All of these test results are better analyzed and nicely displayed together with each package. (h01ger) For Fedora, build jobs can now run in parallel. Two are currently running, now testing reproducibility of 785 source packages from Fedora 23. mock/1.2.3-1.1 has been uploaded to experimental to better build RPMs. (h01ger) Work has started on having automatic build node pools to maximize use of armhf build nodes. (Vagrant Cascadian) diffoscope development Version 43 has been released on December 15th. It has been dubbed as epic! as it contains many contributions that were written around the summit in Athens. Baptiste Daroussin found that running diffoscope on some Tar archives could overwrite arbitrary files. This has been fixed by using libarchive instead of Python internal Tar library and adding a sanity check for destination paths. In any cases, until proper sandboxing is implemented, don't run diffosope on unstrusted inputs outside an isolated, throw-away system. Mike Hommey identified that the CBFS comparator would needlessly waste time scanning big files. It will now not consider any files bigger than 24 MiB 8 MiB more than the largest ROM created by coreboot at this time. An encoding issue related to Zip files has also been fixed. (Lunar) New comparators have been added: Android dex files (Reiner Herrmann), filesystem images using libguestfs (Reiner Herrmann), icons and JPEG images using libcaca (Chris Lamb), and OS X binaries (Clemens Lang). The comparator for Free Pascal Compilation Unit will now only be used when the unit version matches the compiler one. (Levente Polyak) A new multi-file HTML output with on-demand loading of long diffs is available through the --html-dir option. On-demand loading requires jQuery which path can be specified through the --jquery option. The diffs can also be simply browsed for non-JavaScript users or when jQuery is not available. (Joachim Breitner) Example of on-demand loading in diffosope Portability toward other systems has been improved: old versions of GNU diff are now supported (Mike McQuaid), suggestion of the appropriate locale is now the more generic en_US.UTF-8 (Ed Maste), the --list-tools option can now support multiple systems (Mattia Rizzolo, Levente Polyak, Lunar). Many internal changes and code clean-ups have been made, paving the way for parallel processing. (Lunar) Version 44 was released on December 18th fixing an issue affecting .deb lacking a md5sums file introduced in a previous refactoring (Lunar). Support has been added for Mozilla optimized Zip files. (Mike Hommey). The HTML output has been optimized in size (Mike Hommey, Esa Peuha, Lunar), speed (Lunar), and will now properly number lines (Mike Hommey). A message will always be displayed when lines are ignored at the end of a diff (Lunar). For portability and consistency, Python os.walk() function is now used instead of find to perform directory listing. (Lunar) Documentation update Package reviews 143 reviews have been removed, 69 added and 22 updated in the previous week. Chris Lamb reported 12 new FTBFS issues. News issues identified this week: random_order_in_init_py_generated_by_python-genpy, timestamps_in_copyright_added_by_perl_dist_zilla, random_contents_in_dat_files_generated_by_chasen-dictutils_makemat, timestamps_in_documentation_generated_by_pandoc. Chris West did some improvements on the scripts used to manage notes in the misc repository. Misc. Accounts of the reproducible builds summit in Athens were written by Thomas Klausner from NetBSD and Hans-Christoph Steiner from The Guardian Project. Some openSUSE developers are working on a hackweek on reproducible builds which was discussed on the opensuse-packaging mailing-list.

Lunar: Reproducible builds: week 32 in Stretch cycle

The first reproducible world summit was held in Athens, Greece, from December 1st-3rd with the support of the Linux Foundation, the Open Tech Fund, and Google. Faidon Liambotis has been an amazing help to sort out all local details. People at ImpactHub Athens have been perfect hosts. North of Athens from the Acropolis with ImpactHub in the center Nearly 40 participants from 14 different free software project had very busy days sharing knowledge, building understanding, and producing actual patches. Anyone interested in cross project discussions should join the rb-general mailing-list. What follows focuses mostly on what happened for Debian this previous week. A more detailed report about the summit will follow soon. You can also read the ones from Joachim Breitner from Debian, Clemens Lang from MacPorts, Georg Koppen from Tor, Dhiru Kholia from Fedora, and Ludovic Court s wrote one for Guix and for the GNU project. The Acropolis from  Infrastructure Several discussions at the meeting helped refine a shared understanding of what kind of information should be recorded on a build, and how they could be used. Daniel Kahn Gillmor sent a detailed update on how .buildinfo files should become part of the Debian archive. Some key changes compared to what we had in mind at DebConf15: Hopefully, ftpmasters will be able to comment on the updated proposal soon. Packages fixed The following packages have become reproducible due to changes in their build dependencies: fades, triplane, caml-crush, globus-authz. 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 sent proposals on how to make bash reproducible. Alexander Couzens submitted a patch upstream to add support for SOURCE_DATE_EPOCH in grub image generator (#787795). reproducible.debian.net An issue with some armhf build nodes was tracked down to a bad interaction between uname26 personality and new glibc (Vagrant Cascadian). A Debian package was created for koji, the RPM building and tracking system used by Fedora amongst others. It is currently waiting for review in the NEW queue. (Ximin Luo, Marek Marczykowski-G recki) diffoscope development diffoscope now has a dedicated mailing list to better accommodate its growing user and developer base. Going through diffoscope's guts together enabled several new contributors. Baptiste Daroussin, Ed Maste, Clemens Lang, Mike McQuaid, Joachim Breitner all contributed their first patches to improve portability or add new features. Regular contributors Chris Lamb, Reiner Herrmann, and Levente Polyak also submitted improvements. diffoscope hacking session in Athens The next release should support more operating systems, filesystem image comparison via libguestfs, HTML reports with on-demand loading, and parallel processing for the most noticeable improvements. Package reviews 27 reviews have been removed, 17 added and 14 updated in the previous week. Chris Lamb and Val Lorentz filed 4 new FTBFS reports. Misc. Baptiste Daroussin has started to implement support for SOURCE_DATE_EPOCH in FreeBSD in libpkg and the ports tree. Thanks Joachim Breitner and h01ger for the pictures.

Andreas Metzler: Dual boot Debian (stretch) and Windows 10 (UEFI)

I have just assembled and upgraded to a new computer (ct 11 Watt PC with Skylake i5-6500) and chose to go from BIOS/MBR to UEFI/GPT. The computer needs to also run Windows (in this case 10) and so I had googled in vain before for a matching dual-boot howto. It turned out to be unnecessary, it is straightforward.
  1. Install Windows and leave some space for Linux. (I used rufus to build a UEFI USB install image).
  2. Install Debian. Stretch-Alpha4 di just worked and adds a entry for Windows to the grub menu
  3. Reboot and enter UEFI setup, and select the Debian installation as boot option.

Lunar: Reproducible builds: week 29 in Stretch cycle

What happened in the reproducible builds effort this week: Toolchain fixes Emmanuel Bourg uploaded eigenbase-resgen/1.3.0.13768-2 which uses of the scm-safe comment style by default to make them deterministic. Mattia Rizzolo started a new thread on debian-devel to ask a wider audience for issues about the -Wdate-time compile time flag. When enabled, GCC and clang print warnings when __DATE__, __TIME__, or __TIMESTAMP__ are used. Having the flag set by default would prompt maintainers to remove these source of unreproducibility from the sources. Packages fixed The following packages have become reproducible due to changes in their build dependencies: bmake, cyrus-imapd-2.4, drobo-utils, eigenbase-farrago, fhist, fstrcmp, git-dpm, intercal, libexplain, libtemplates-parser, mcl, openimageio, pcal, powstatd, ruby-aggregate, ruby-archive-tar-minitar, ruby-bert, ruby-dbd-odbc, ruby-dbd-pg, ruby-extendmatrix, ruby-rack-mobile-detect, ruby-remcached, ruby-stomp, ruby-test-declarative, ruby-wirble, vtprint. 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: reproducible.debian.net The fifth and sixth armhf build nodes have been set up, resulting in five more builder jobs for armhf. More than 10,000 packages have now been identified as reproducible with the reproducible toolchain on armhf. (Vagrant Cascadian, h01ger) Helmut Grohne and Mattia Rizzolo now have root access on all 12 build nodes used by reproducible.debian.net and jenkins.debian.net. (h01ger) reproducible-builds.org is now linked from all package pages and the reproducible.debian.net dashboard. (h01ger) profitbricks-build5-amd64 and profitbricks-build6-amd64, responsible for running amd64 tests now run 398.26 days in the future. This means that one of the two builds that are being compared will be run on a different minute, hour, day, month, and year. This is not yet the case for armhf. FreeBSD tests are also done with 398.26 days difference. (h01ger) The design of the Arch Linux test page has been greatly improved. (Levente Polyak) diffoscope development Three releases of diffoscope happened this week numbered 39 to 41. It includes support for EPUB files (Reiner Herrmann) and Free Pascal unit files, usually having .ppu as extension (Paul Gevers). The rest of the changes were mostly targetting at making it easier to run diffoscope on other systems. The tlsh, rpm, and debian modules are now all optional. The test suite will properly skip tests that need optional tools or modules when they are not available. As a result, diffosope is now available on PyPI and thanks to the work of Levente Polyak in Arch Linux. Getting these versions in Debian was a bit cumbersome. Version 39 was uploaded with an expired key (according to the keyring on ftp.debian.org which will hopefully be updated soon) which is currently handled by keeping the files in the queue without REJECTing them. This prevented any other Debian Developpers to upload the same version. Version 40 was uploaded as a source-only upload but failed to build from source which had the undesirable side effect of removing the previous version from unstable. The package faild to build from source because it was built passing -I to debbuild. This excluded the ELF object files and static archives used by the test suite from the archive, preventing the test suite to work correctly. Hopefully, in a nearby future it will be possible to implement a sanity check to prevent such mistakes in the future. It has also been identified that ppudump outputs time in the system timezone without considering the TZ environment variable. Zachary Vance and Paul Gevers raised the issue on the appropriate channels. strip-nondeterminism development Chris Lamb released strip-nondeterminism version 0.014-1 which disables stripping Mono binaries as it is too aggressive and the source of the problem is being worked on by Mono upstream. Package reviews 133 reviews have been removed, 115 added and 103 updated this week. Chris West and Chris Lamb reported 57 new FTBFS bugs. Misc. The video of h01ger and Chris Lamb's talk at MiniDebConf Cambridge is now available. h01ger gave a talk at CCC Hamburg on November 13th, which was well received and sparked some interest among Gentoo folks. Slides and video should be available shortly. Frederick Kautz has started to revive Dhiru Kholia's work on testing Fedora packages. Your editor wish to once again thank #debian-reproducible regulars for reviewing these reports weeks after weeks.
