A new version of drat arrived on CRAN overnight, once again taking advantage of the fully automated process available for such packages with few reverse depends and no open issues. As we remarked at the last release fourteen months ago when we scored the same nice outcome: Being a simple package can have its upsides This release is mostly the work of Felix Ernst who took on what became a rewrite of how binary macOS packages are handled. If you need to distribute binary packages for macOS users, this may help. Two more small updates were made, see below for full details. drat stands for drat R Archive Template, and helps with easy-to-create and easy-to-use repositories for R packages. Since its inception in early 2015 it has found reasonably widespread adoption among R users because repositories with marked releases is the better way to distribute code. As your mother told you: Friends don t let friends install random git commit snapshots. Rolled-up releases it is. drat is easy to use, documented by five vignettes and just works. The NEWS file summarises the release as follows:

Changes in drat version 0.1.6 (2020-05-29)

• Changes in drat functionality
  • Support for the various (current) macOS binary formats was rewritten (Felix Ernst in #89 fixing #88).
  • Travis CI use was updated to R 4.0.0 and bionic (Dirk).
  • A drat repo was added to the README (Thomas Fuller in #86)

Courtesy of CRANberries, there is a comparison to the previous release. More detailed information is on the drat page. If you like this or other open-source work I do, you can now sponsor me at GitHub. For the first year, GitHub will match your contributions.

Congratulations!

I recently wrote a final paper on the history of written numerals. In the process, I discovered this fascinating tidbit that didn t really fit in my paper, but I wanted to put it somewhere. So I m writing about it here. If I were to ask you to count as high as you could on your fingers you d probably get up to 10 before running out of fingers. You can t count any higher than the number of fingers you have, right? The Romans could! They used a place-value system, combined with various gestures to count all the way up to 9,999 on two hands.

The System (Note that in this diagram 60 is, in fact, wrong, and this picture swaps the hundreds and the thousands.) We ll start with the units. The last three fingers of the left hand, middle, ring, and pinkie, are used to form them. Zero is formed with an open hand, the opposite of the finger counting we re used to. One is formed by bending the middle joint of the pinkie, two by including the ring finger and three by including the middle finger, all at the middle joint. You ll want to keep all these bends fairly loose, as otherwise these numbers can get quite uncomfortable. For four, you extend your pinkie again, for five, also raise your ring finger, and for six, you raise your middle finger as well, but then lower your ring finger. For seven you bend your pinkie at the bottom joint, for eight adding your ring finger, and for nine, including your middle finger. This mirrors what you did for one, two and three, but bending the finger at the bottom joint now instead. This leaves your thumb and index finger for the tens. For ten, touch the nail of your index finger to the inside of your top thumb joint. For twenty, put your thumb between your index and middle fingers. For thirty, touch the nails of your thumb and index fingers. For forty, bend your index finger slightly towards your palm and place your thumb between the middle and top knuckle of your index finger. For fifty, place your thumb against your palm. For sixty, leave your thumb where it is and wrap your index finger around it (the diagram above is wrong). For seventy, move your thumb so that the nail touches between the middle and top knuckle of your index finger. For eighty, flip your thumb so that the bottom of it now touches the spot between the middle and top knuckle of your index finger. For ninety, touch the nail of your index finger to your bottom thumb joint. The hundreds and thousands use the same positions on the right hand, with the units being the thousands and the tens being the hundreds. One account, from which the picture above comes, swaps these two, but the first account we have uses this ordering. Combining all these symbols, you can count all the way to 9,999 yourself on just two hands. Try it!

History

The Venerable Bede The first written record of this system comes from the Venerable Bede, an English Benedictine monk who died in 735. He wrote De computo vel loquela digitorum, On Calculating and Speaking with the Fingers, as the introduction to a larger work on chronology, De temporum ratione. (The primary calculation done by monks at the time was calculating the date of Easter, the first Sunday after the first full moon of spring). He also includes numbers from 10,000 to 1,000,000, but its unknown if these were inventions of the author and were likely rarely used regardless. They require moving your hands to various positions on your body, as illustrated below, from Jacob Leupold s Theatrum Arilhmetico-Geometricum, published in 1727:

The Romans If Bede was the first to write it, how do we know that it came from Roman times? It s referenced in many Roman writings, including this bit from the Roman satirist Juvenal who died in 130:

Felix nimirum qui tot per saecula mortem distulit atque suos iam dextera computat annos. Happy is he who so many times over the years has cheated death And now reckons his age on the right hand.

Because of course the right hand is where one counts hundreds! There s also this Roman riddle:

Nunc mihi iam credas fieri quod posse negatur: octo tenes manibus, si me monstrante magistro sublatis septem reliqui tibi sex remanebunt. Now you shall believe what you would deny could be done: In your hands you hold eight, as my teacher once taught; Take away seven, and six still remain.

If you form eight with this system and then remove the symbol for seven, you get the symbol for six!

Welcome to gambaru.de. Here is my monthly report that covers what I have been doing for Debian. If you re interested in Java, Games and LTS topics, this might be interesting for you. Debian Games

• I sponsored a new release of hexalate for Unit193 and icebreaker for Andreas Gnau. The latter is a reintroduction.
• New upstream releases this month: freeorion and hyperrogue.
• I backported freeciv and freeorion to Stretch.

Debian Java

• New upstream releases and one update: sweethome3d, sweethome3d-furniture, sweethome3d-furniture-editor, sweethome3d-textures-editor (update), libsambox-java, libsejda-java, pdfsam, easymock, jboss-modules, jboss-xnio and undertow.
• I fixed one RC bug in libsejda-io-java (#874494) and investigated another one (#869266) in commons-httpclient which could be closed.
• The new build-dependencies of jboss-xnio, wildfly-client-config and wildfly-common, were accepted into the archive this month.
• I spent some quality time on fixing #874579 in libhibernate-validator-java. This was the last blocking bug for pdfsam which I could finally upload to unstable. It s a really great JavaFX application. Check it out!
• I sponsored another update of libimglib2-java for Ghislain Vaillant and simplyhtml, freeplane and knopflerfish-osgi for Felix Natter.
• I also fixed RC bug #871348 in robocode, a Java programming game and #871347 in tycho.

Debian LTS This was my nineteenth month as a paid contributor and I have been paid to work 15,75 hours on Debian LTS, a project started by Rapha l Hertzog. In that time I did the following:

• From 18. September to 24. September I was in charge of our LTS frontdesk. I triaged bugs in poppler, binutils, kannel, wordpress, libsndfile, libexif, nautilus, libstruts1.2-java, nvidia-graphics-drivers, p3scan, otrs2 and glassfish.
• DLA-1108-1. Issued a security update for tomcat7 fixing 1 CVE.
• DLA-1116-1. Issued a security update for poppler fixing 3 CVE.
• DLA-1119-1. Issued a security update for otrs2 fixing 4 CVE.
• DLA-1122-1. Issued a security update for asterisk fixing 1 CVE. I also investigated CVE-2017-14099 and CVE-2017-14603. I decided against a backport because the fix was too intrusive and the vulnerable option is disabled by default in Wheezy s version which makes it a minor issue for most users.
• I submitted a patch for Debian s reportbug tool. (#878088) During our LTS BoF at DebConf 17 we came to the conclusion that we should implement a feature in reportbug that checks whether the bug reporter wants to report a regression for a recent security update. Usually the LTS and security teams receive word from the maintainer or users who report issues directly to our mailing lists or IRC channels. However in some cases we were not informed about possible regressions and the new feature in reportbug shall ensure that we can respond faster to such reports.
• I started to investigate the open security issues in wordpress and will complete the work in October.

Misc

• I packaged a new version of xarchiver. Thanks to the work of Ingo Br ckl xarchiver can handle almost all archive formats in Debian now.

QA upload

• I did a QA upload of xball, an ancient game from the 90ies that simulates bouncing balls. It should be ready for another decade at least.

Thanks for reading and see you next time.

Welcome to gambaru.de. Here is my monthly report that covers what I have been doing for Debian. If you re interested in Java, Games and LTS topics, this might be interesting for you. Debian Games

• I backported freeciv, freeorion and minetest to stretch-backports.
• The bug fix (#866378) for 3dchess also landed in Stretch and Jessie.
• I sponsored Lugaru for Vincent Prat and Martin Erik Werner, a really cool 3D fighting game featuring a rabbit. The game is dfsg-free now and will replace openlugaru.
• I uploaded fifechan to unstable and packaged new upstream versions of fife, unknown-horizons, adonthell-data and hyperrogue.
• I fixed bugs in bloboats (#864534), lordsawar (RC #866988), kraptor (#826423), pathogen (#845991), fretsonfire (#866426), blockout2 (#826416), boswars (#827112), kanatest (RC #868315, fix also backported to Stretch), overgod (#827114), morris (#829948, #721834, #862224), mousetrap (#726842), alsoft-conf (#784052, #562898) and nikwi (#835625)
• I uploaded a new revision of clanlib and teg fixing Perl transition bugs. The patches were provided by gregor herrmann. I added myself to Uploaders in case of teg because the package was missing a human maintainer.
• I adopted trackballs after I discovered #868983 where Henrique de Moraes Holschuh called attention to a new fork of Trackballs. The current version was broken and unplayable and it was only a matter of time before the game was removed from Debian. I could fix a couple of bugs, forwarded some issues upstream and I believe a nice game was saved.
• I uploaded Bullet 2.86.1 to unstable and completed another Bullet transition.

Debian Java

• Almost all PDFsam dependencies were accepted into the archive this month. I had to update some of them and removed patches that were needed for the initial bootstrapping. I also uploaded libmetadata-extractor-java to unstable. Now only fontawesomefx is missing to complete the PDFsam update.
• I cleaned up vecmath.
• I prepared a security update for undertow issued as DSA 3906-1.
• New upstream releases: jansi, jansi-native, libpdfbox-java, qdox2.
• Bug fixes: felix-bundlerepository (RC #868074), netbeans (RC #868931, #865715), libnb-platform18-java (RC #868923), easymock (RC #869018).

Debian LTS This was my seventeenth month as a paid contributor and I have been paid to work 23,5 hours on Debian LTS, a project started by Rapha l Hertzog. In that time I did the following:

• From 24. July until 31. July I was in charge of our LTS frontdesk. I triaged bugs in tinyproxy, varnish, freerdp, ghostscript, gcc-4.6, gcc-4.7, fontforge, teamspeak-server, teamspeak-client, qpdf, nvidia-graphics-drivers and sipcrack. I also pinged Diego Biurrun for more information about the next libav update and replied to questions on the debian-lts mailing list and LTS IRC channel.
• DLA 1034-1. Issued a security update for php5 fixing 5 CVE. I discussed CVE-2017-11362 with the security team. We came to the conclusion that it was no security issue but just a normal bug.
• DLA 1036-1. Issued a security update for gsoap fixing 1 CVE.
• DLA 1037-1. Issued a security update for catdoc fixing 1 CVE.
• DLA 613-2. Issued a regression update for roundcube.
• DLA 1045-1. Issued a security update for graphicsmagick fixing 10 CVE.
• DLA 1047-1. Issued a security update for supervisor fixing 1 CVE.
• DLA-1048-1. Issued a security update for ghostscript fixing 8 CVE.

Non-maintainer upload

• I uploaded the security fix for spice to unstable which was already fixed in Stretch and earlier versions.

Thanks for reading and see you next time.

Here's what happened in the Reproducible Builds effort between Sunday June 4 and Saturday June 10 2017: Past and upcoming events On June 10th, Chris Lamb presented at the Hong Kong Open Source Conference 2017 on reproducible builds. Patches and bugs filed

• Chris Lamb: #864082 filed against fontconfig, forwarded upstream

Reviews of unreproducible packages 7 package reviews have been added, 10 have been updated and 14 have been removed in this week, adding to our knowledge about identified issues. Weekly QA work During our reproducibility testing, FTBFS bugs have been detected and reported by:

• Adrian Bunk (4)
• Chris Lamb (1)
• Christoph Biedl (1)
• Niko Tyni (1)

Two FTBFS issues of LEDE (exposed in our setup) were found and were fixed:

• build: ensure that flock is available for make download (Felix Fietkau)
• include/toplevel: set env GIT_ASKPASS=/bin/true (Alexander 'lynxis' Couzens)

diffoscope development

• Chris Lamb: Some code style improvements

tests.reproducible-builds.org: Alexander 'lynxis' Couzens made some changes for testing LEDE and OpenWrt:

• Build tar before downloading everything: On system without tar --sort=name we need to compile tar before downloading everything
• Set CONFIG_AUTOREMOVE to reduce required space
• Create a workaround for signing keys: LEDE signs the release with a signing key, but generates the signing key if it's not present. To have a reproducible release we need to take care of signing keys.
• openwrt_get_banner(): use staging_dir instead of build_dir because the former is persistent among the two builds.
• Don't build all packages to improve development speed for now.
• Only build one board instead of all boards. Reducing the build time improves developing speed. Once the image is reproducible we will enable more boards.
• Disable node_cleanup_tmpdirs

Hans-Christoph Steiner, for testing F-Droid:

• Do full git reset/clean like Jenkins does
• hard code WORKSPACE dir names, as WORKSPACE cannot be generated from $0 as it's a temporary name.

Daniel Shahaf, for testing Debian:

• Remote scheduler:
  • English fix to error message.
  • Allow multiple architectures in one invocation.
  • Refactor: Break out a helper function. Rename variable to disambiguate with scheduling_args.message.
• Include timestamps in logs
• Set timestamps to second resolution (was millisecond by default).

Holger 'h01ger' Levsen, for testing Debian:

• Improvements to the breakages page:
  • List broken packages and diffoscope problems first, and t.r-b.o problems last.
  • Reword, drop 'caused by'.
• Add niceness to our list of variations, running with niceness of 11 for the first build and niceness of 10 for the second one. Thanks to Vagrant for the idea.
• Automatic scheduler:
  • Reschedule after 12h packages that failed with error 404
  • Run scheduler every 3h instead of every 6h
• Add basic README about the infrastructure and merge Vagrants notes about his console host.

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

Welcome to gambaru.de. Here is my monthly report that covers what I have been doing for Debian. If you re interested in Android, Java, Games and LTS topics, this might be interesting for you. Debian Android

• I sponsored a new package for Seamlik called android-platform-tools-analytics-library.

Debian Games

• We have entered the final straight for Stretch, so I kept a close eye on new game releases and bug reports in packages which I think should be part of the next stable release. Bzflag is certainly one of them, a tank battling game that can be played in the first-person perspective and which has arrived in version 2.4.8. I also packaged new releases of trigger-rally, a racing game, Renpy, pygame-sdl2 and Minetest.
• B lint R czey introduced libopenhmd to Debian a while ago and asked me in #845657 to enable OpenHMD support for neverball. Neverball is now the first game in the archive, at least as far as I know, that is ready for virtual reality. I have never tried it though because I don t own the necessary gear from Oculus myself but it sounds like a cool feature.
• A user of caveexpress reported a bug (#847147) in one level that prevented him from finishing it. I forwarded this one to upstream and he was able to quickly fix the issue and I could release 2.4+git20160609-3 later.
• I triaged several RC bugs which were reported against our D language games and it turned out that the bug was in gdc (#845377).
• I also made some small improvements to monopd s packaging and applied a patch from Laurent Bigonville to Freeciv that corrected a problem with AppData files (#848720).
• I worked around another RC FTBFS bug in spring (#846921) which is apparently a regression in binutils (#847356) but its maintainer does not consider this to be release critical.
• I tried to fix #848063 in ri-li but it seems to surface again under special circumstances. Since compilation works on all buildds for all release architectures and on my systems I downgraded the severity to important.
• I uploaded Bullet 2.85.1 to experimental. It is currently waiting in the NEW queue due to the SONAME bump and because I decided to simplify the packaging. I don t think it is longer worth it to provide several standalone binary packages. All Bullet 2 and 3 core libraries can be found in libbullet2.85 now while all the extra stuff is part of libbullet-extras2.85.
• Last but not least I released debian-games 1.7 and updated the list of games. Castle Combat was removed this month from Debian.

Debian Java

• I promised to complete my work on Netbeans and spent several hours on completing this goal. Although I am aware of the package s obstacles by now it never ceases to amaze me how many build failures occur due to the apparent mismatch between Debian (build-)dependencies and the ones upstream is using. This time I got stuck when several core modules could not be built from source because they required classes from OpenJDK 9. Since JDK 9 will not be released with Stretch I am afraid to say that Netbeans 8.2 won t be part of it. I worked around these issues by replacing the modules with versions from 8.1 but this is obviously just a very crude hack. Nevertheless the new package is available in experimental now.
• New upstream releases this month: activemq, netbeans, libnb-platform18-java, svnclientadapter, jackrabbit, jboss-xnio, undertow.
• Package updates: jboss-classfilewriter, jboss-logging, libpicocontainer-java.
• RC bug fixes: jruby-maven-plugins (#844841), vorbis-java (#844753), jackson-datatype-guava (#849449), triaged libhamcrest-java (#846116).
• I sponsored freeplane 1.5.18-1 for Felix Natter.

Debian LTS This was my tenth month as a paid contributor and I have been paid to work 13,5 hours on Debian LTS, a project started by Rapha l Hertzog. In that time I did the following:

• From 12. December until 18. December I was in charge of our LTS frontdesk. I triaged bugs in jasper, openjdk-6, bluez, game-music-emu, simplesamlphp, imagemagick, nagios3, most, rabbitmq-server, html5lib and dcmtk.
• DLA-742-1. Issued a security update for chrony fixing 1 CVE. This update was prepared by Vincent Blut.
• DLA-745-1. Issued a security update for most fixing 1 CVE.
• DLA-746-1. Issued a security update for tomcat6 fixing 1 CVE and two regressions from previous updates which were reported to Debian s bug tracker.
• DLA-747-1. Issued a security update for libupnp fixing 1 CVE.
• DLA-748-1. Issued a security update for libupnp4 fixing 1 CVE.
• DLA-746-2. Issued a regression update for tomcat6.
• DLA-753-1. Issued a security update for tomcat7 fixing 1 CVE and three regressions that were similar in nature to the ones fixed in Tomcat 6.
• DLA-761-1. Issued a security update for python-bottle fixing 1 CVE.
• DLA-763-1. Issued a security update for squid3 fixing 1 CVE.
• DLA-766-1. Issued a security update for libcrypto++ fixing 1 CVE.
• I also worked on two CVEs for Asterisk, an Open Source PBX and telephony toolkit. The work is done and can currently be found at this location. I asked on the debian-lts mailing list for feedback and testing and already got some positive feedback. I will wait a few more days before I release the security update.

Non-maintainer uploads

• I did two NMUs this month. I sponsored an upload of libtorrent for Peter Pentchev fixing #828414 and I fixed a trivial bug in gnash myself (#845847).

Welcome to gambaru.de. Here is my monthly report that covers what I have been doing for Debian. If you re interested in Android, Java, Games and LTS topics, this might be interesting for you. Debian Android

• I sponsored a new upstream release of android-platform-tools-base prepared by Kai-Chung Yan and Chirayu Desai.

Debian Games

• I packaged a new upstream release of hyperrogue, a rogue-like game settled in a non-euclidian world, fixing one RC bug (#811991). I uploaded two more revisions later that addressed build failures on arm64 and hppa.
• I fixed more RC bugs (build failures with GCC-6) in torus-trooper (#835712) and fife (#811858).
• I packaged new upstream releases of pygame-sdl2, renpy, freeorion, netrek-client-cow, redeclipse, redeclipse-data, hitori, atomix, adonthell and adonthell-data.
• I updated gtkballs and fixed a documentation bug (#820588) but also a /usr/share/locale issue that prevented the actual use of the translations.
• I raised the severity of #797998 to grave in unknown-horizons because the game cannot be started currently. In order to fix this issue I packaged a new build-dependency, fifechan, which is currently awaiting approval by the FTP team. As soon as fifechan got accepted I will upload new upstream releases of fife and unknown-horizons.
• I released debian-games 1.5, a Debian blend and collection of games metapackages.
• Hardening-wrapper has been deprecated for some time and this issue became release critical now. I updated cookietool, alex4 and netrek-client-cow to use dpkg-buildflags instead.
• Together with Russel Coker I packaged a new upstream release of warzone2100. This package would benefit from a new regular uploader. If you are interested in it, please get involved. (Same story for hyperrogue, redeclipse, renpy and unknown-horizons and many other games.)
• I started a new Bullet transition (#839243). The package is currently waiting in the NEW queue and I hope to complete this work in October.
• I triaged #838199 and reassigned the issue to fonts-roboto. Initially I prepared an NMU but eventually the maintainer uploaded a new revision himself. It is now possible to install the hinted and unhinted versions of fonts-roboto together which also resolved former installation problems with kodi and freeorion.

Debian Java

• I packaged new upstream releases of undertow, activemq and jackrabbit.
• I fixed RC bugs in libphonenumber (#836768), wagon2 (#837022) and activemq (#839244).
• I updated syncany in experimental and simplified the packaging a little. Unfortunately upstream has been on hiatus for the past year and we haven t seen new releases in the meantime. Nevertheless give it a try, even though it is still alpha software, it s an useful cloud-storage and synchronization tool.
• I sponsored a new upstream release of freeplane for Felix Natter.
• I prepared and uploaded security updates for jackrabbit and zookeeper in Jessie.

Debian LTS This was my eight month as a paid contributor and I have been paid to work 12,25 hours on Debian LTS, a project started by Rapha l Hertzog. In that time I did the following:

• From 12. September until 19. September I was in charge of our LTS frontdesk. I triaged bugs in tiff3, mysql-5.5, curl, dropbear, mantis, icu, dwarfutils, jackrabbit, zendframework, zookeeper and graphicsmagick. For the latter I skimmed through all commits since the last version to identify the patches that fix the recent issues in graphicsmagick. I also answered questions on the mailing list and contacted Diego Biurrun again about his progress with libav. It is now anticipated that Hugo Lefeuvre and Diego will issue a new libav security release this month.
• I reviewed and tested a patch by Rapha l Hertzog for roundcube.
• DLA-629-1. Issued a security update for jackrabbit fixing 1 CVE.
• DLA-630-1. Issued a security update for zookeeper fixing 1 CVE.
• DLA-633-1. Issued a security update for wordpress fixing 7 CVE. This one also required backports of certain functions from newer releases and a database upgrade that required careful testing.
• I also issued DLA-622-1 and DLA-623-1, two security issues that I already mentioned last month. It was discovered that Debian s versions of Tomcat were vulnerable to a root privilege escalation issue. However it was also necessary that another exploit, for instance in a web application, could be used to gain write access as the tomcat user. Former security issues were already fixed and new ones are not known. Nevertheless since a zero-day exploit could not be ruled out, the issue was embargoed for a month to give other distributions time to fix this issue as well. You can read more about this topic at legalhackers.com.

Non-maintainer uploads

• I fixed various RC bugs in several games that are not maintained by the Games Team. The following games will be available in Stretch again soon: solarwolf, enigma, open-invaders, crrcsim, noiz2sa, csmash, csmash-demosong and glob2.

Misc

• I packaged a new upstream release of MediathekView.
• I uploaded a new revision of xarchiver and applied a patch from Helmut Grohne that made it possible to cross-build the package.

Welcome to gambaru.de. Here is my monthly report that covers what I have been doing for Debian. If you re interested in Android, Java, Games and LTS topics, this might be interesting for you. Debian Android

• This was the final month of the Google Summer of Code and the students achieved the main goal of packaging the Android SDK. It is now possible to build Android apps on Debian with packages only from the main distribution (apt install android-sdk). Chirayu Desai fixed the last remaining issue in android-platform-system-core (#827216). That also means apktool is now ready to rebuild Android applications. You can find more information about the students work at wiki.debian.org and on their individual pages Chirayu Desai, Kai-Chung Yan and Mouaad Aallam.
• I sponsored a new upstream release (2.2.0) of apktool for Chirayu Desai.
• I also reviewed and sponsored the following packages for Kai-Chung and Chirayu Desai (RC bug fixes and new upstream releases): android-platform-dalvik, android-platform-frameworks-base, android-sdk-meta.

Debian Games

• I started the month with package updates for foobillardplus, tuxpuck, etw, cube2, cube2-data and neverball.
• I released a new revision of triplane to fix a reproducible build issue.
• I packaged a new upstream release of springlobby.
• I fixed GCC-6 FTBFS bugs in stormbaancoureur and love and updated both packages to use modern Debian helpers (stormbaancoureur needed it badly).
• I invested some time to package Liquidwar 6 (#680023) and attached my preliminary work to the bug report. Liquidwar 6 has been in the works for a long time now and is a complete rewrite of the original Liquidwar game. The graphics are much more polished and dozens of new levels are available. I didn t complete my work on Liquidwar 6 because, at least on my system, the game constantly consumes 100% CPU time. Network modus isn t finished yet and it still depends on SDL 1. Nowadays I m only interested in SDL 2 (or similar) games though because I think the library is more future-proof and SDL 1 will probably become a burden for future maintainers.
• In the second half of the month I fixed a couple of RC bugs again caused by the Boost 1.61 transition and yes still more GCC-6 bugs : libclaw (GCC-6 and Boost 1.61 issues, new upstream release), freeorion (Boost 1.61 FTBFS, #833773. This one was arguably a regression in Boost 1.61 and I filed #833794 because of it), pokerth (GCC-6 RC bugs. I also took the opportunity to implement systemd support for pokerth-server and I modified the package to run the server as the _pokerth system user out-of-the-box.), 0ad (missing build-dependency on python).
• Even music packages can pile up bug reports, so I went ahead and updated fretsonfire-songs-muldjord and fretsonfire-songs-sectoid.
• In the last days of August 2016 I packaged a new upstream release of redeclipse and redeclipse-data, a first-person shooter. The older version was network-incompatible and long unsupported.

Debian Java

• I packaged new upstream releases of libjide-oss-java, undertow, jboss-xnio, hawtjni.
• I fixed RC bugs in libfreemaker-java, airlift-slice, japi-compliance-checker (was already fixed by Emmanuel Bourg but never uploaded), lucene2, libbtm-java, javassist, commons-math, libslf4j-java, surefire, maven-invoker, maven-scm and sweethome3d-furniture-editor.
• I triaged RC bug #834744 in xmlgraphics-commons and lowered the severity because the build failure was not reproducible in a clean cowbuilder environment. Another RC bug was reported against mina2 but I also couldn t reproduce the test failure hence I lowered the severity and marked #834682 as unreproducible.
• Another RC bug was reported against bookkeeper, #835277, allegedly the issue was caused by a missing artifact. After some investigation it turned out that the recent update of libprotobuf-java, one of bookkeeper s build-dependencies, used the wrong pom.xml and thus different Maven coordinates for the artifact. I filed #835358 and later #835514 against libprotobuf-java and both issues got resolved quickly.
• I reported #835354 against libitext-java because the package was uninstallable.
• I sponsored a new upstream release of freeplane for Felix Natter.

Debian LTS This was my seventh month as a paid contributor and I have been paid to work 14,75 hours on Debian LTS, a project started by Rapha l Hertzog. In that time I did the following:

• From 01. August to 07. August I was in charge of our LTS frontdesk. I triaged CVEs in wordpress, mysql-5.5, libsys-syslog-perl, libspring-java, curl and squid and answered questions on the debian-lts mailing list.
• DLA-586-1. Issued a security update for curl fixing 2 CVE.
• DLA-585-1. Announced the security update for firefox-esr which was prepared by Mike Hommey.
• I was involved in an embargoed security issue that currently affects two source packages in Wheezy. The update will be released on 15. September 2016 and will be coordinated with Debian s Security Team and other distributions. I will add more information next month.
• DLA-610-1. I spent most of the time this month on triaging and fixing security issues in tiff3, a library providing support for the Tagged Image File Format (TIFF). 99 source packages currently build-depend on this library in Wheezy. In total I triaged 35 CVEs and fixed 23 of them. I could confirm that CVE-2015-1547, CVE-2016-5322, CVE-2016-5314, CVE-2016-5315, CVE-2016-5316, CVE-2016-5317 and CVE-2016-5320 were duplicates of other CVEs fixed in this update. The update hardened the library and fixed possible denial-of-service (application crash) and arbitrary code execution issues. I tested whenever possible against the provided reproducers (malicious tiff images). The tiff3 package now includes all currently available patches. Most of the current open vulnerabilities do not directly affect end-users since no binary package has been provided for the tiff tools in Wheezy. However they can still pose a threat to people who build these tools from source manually. Though the majority of users should not be affected. It is also unlikely that the remaining issues will be fixed by tiff s upstream developers since they decided to remove the affected applications from newer releases but again most of them can t be exploited since the tools are not built by default in this version.

Non-maintainer uploads

• I did a NMU for pacman fixing one GCC-6 RC bug.

QA

• I packaged a new upstream release of pygccxml and worked around a RC bug that threatened to remove spring. For similar reasons I filed #835121 against castxml that got quickly fixed by Gert Wollny.

What happened in the Reproducible Builds effort between June 26th and July 2nd 2016: Read on to find out why we're lagging some weeks behind ! GSoC and Outreachy updates

• Ceridwen described using autopkgtest code to communicate with containers and how to test the container handling.
• reprotest 0.1 has been accepted into Debian unstable, and any user reports, bug reports, feature requests, etc. would be appreciated. This is still an alpha release, and nothing is set in stone.

Toolchain fixes

• Matthias Klose uploaded doxygen/1.8.11-3 to Debian unstable (closing #792201) with the upstream patch improving SOURCE_DATE_EPOCH support by using UTC as timezone when parsing the value. This was the last patch we were carrying in our repository, thus this upload obsoletes the version in our experimental repository.
• cmake/3.5.2-2 was uploaded by Felix Geyer, which sorts file lists obtained with file(GLOB).
• Dmitry Shachnev uploaded sphinx/1.4.4-2, which fixes a timezone related issue when SOURCE_DATE_EPOCH is set.

With the doxygen upload we are now down to only 2 modified packages in our repository: dpkg and rdfind. Weekly reports delay and the future of statistics To catch up with our backlog of weekly reports we have decided to skip some of the statistics for this week. We might publish them in a future report, or we might switch to a format where we summarize them more (and which we can create (even) more automatically), we'll see. We are doing these weekly statistics because we believe it's appropriate and useful to credit people's work and make it more visible. What do you think? We would love to hear your thoughts on this matter! Do you read these statistics? Somewhat? Actually, thanks to the power of notmuch, Holger came up with what you can see below, so what's missing for this week are the uploads fixing irreprodubilities. Which we really would like to show for the reasons stated above and because we really really need these uploads to happen But then we also like to confirm the bugs are really gone, which (atm) requires manual checking, and to look for the words "reproducible" and "deterministic" (and spelling variations) in debian/changelogs of all uploads, to spot reproducible work not tracked via the BTS. And we still need to catch up on the backlog of weekly reports. Bugs submitted with reproducible usertags It seems DebCamp in Cape Town was hugely successful and made some people get a lot of work done: 61 bugs have been filed with reproducible builds usertags and 60 of them had patches:

Package reviews 437 new reviews have been added (though most of them were just linking the bug, "only" 56 new issues in packages were found), an unknown number has been been updated and 60 have been removed in this week, adding to our knowledge about identified issues. 4 new issue types have been found:

• random_order_of_pdf_ids_generated_by_latex
• unsorted_pdl_output
• timestamps_in_output_generated_by_txt2tags
• random_order_in_documentation_generated_by_naturaldocs

Weekly QA work 98 FTBFS bugs have been reported by Chris Lamb and Santiago Vila. diffoscope development

• Reiner Herrmann clarified the help text for the input arguments.
• #829115 against diffoscope by Axel Beckert and Mattia Rizzolo:: /comparators/ps.py: TypeError: cannot use a string pattern on a bytes-like object.

strip-nondeterminism development

• Chris Lamb made sure that .zhfst files are treated as ZIP files.

tests.reproducible-builds.org

• Mattia Rizzolo uploaded pbuilder/0.225.1~bpo8+1 to jessie-backports and it has been installed on all build nodes. As a consequence all armhf and i386 builds will be done with eatmydata; this will hopefully cut down the build time by a noticable factor.

Misc. This week's edition was written by Mattia Rizzolo, Reiner Herrmann, Ceridwen and Holger Levsen and reviewed by a bunch of Reproducible builds folks on IRC.

Jessie was released one year ago now and the Java Team has been busy preparing the next release. Here is a quick summary of the current state of the Java packages:

• A total of 136 packages have been added, 63 removed, 213 upgraded to a new upstream release, and 145 updated. We are now maintaining 892 packages (+12.34%).
• OpenJDK 8 is now the default Java runtime in testing/unstable. OpenJDK 7 has been removed, as well as several packages that couldn't be upgraded to work with OpenJDK 8 (avian, eclipse).
• OpenJDK 9 is available in experimental. As a reminder, it won't be part of the next release; OpenJDK 8 will be the only Java runtime supported for Stretch.
• Netbeans didn't make it into Jessie, but it is now back and up to date.
• The main build tools are close to their latest upstream releases, especially Maven and Gradle which were seriously lagging behind.
• Scala has been upgraded to the version 2.11. We are looking for Scala experts to maintain the package and its dependencies.
• Freemind has been removed due to lack of maintenance, Freeplane is recommended instead.
• The reproducibility rate has greatly improved, climbing from 50% to 75% in the past year.
• Backports are continuously provided for the key packages and applications: OpenJDK 8, OpenJFX, Ant, Maven, Gradle, Tomcat 7 & 8, Jetty 8 & 9, jEdit.
• The transition to Maven 3 has been completed, and packages are no longer built with Maven 2.
• We replaced several obsolete libraries and transitioned them to their latest versions - for example, asm2, commons-net1 and commons-net2. Groovy 1.x was replaced with Groovy 2, and we upgraded BND, an important tool to develop with OSGi, and more than thirty of its reverse-dependencies from the 1.x series to version 2.4.1.
• New packaging tools have been created to work with Gradle (gradle-debian-helper) and Ivy (ivy-debian-helper).

Outlook, goals and request for help

• We have several difficult transitions ahead: BND 3, Tomcat 7 to 8, Jetty 8 to 9, ASM 5, and of course Java 9. Any help would be welcome.
• Eclipse is severely outdated and currently not part of testing. We would like to update this important piece of software and its corresponding modules to the latest upstream release, but we need more active people who want to maintain them. If you care about the Eclipse ecosystem, please get in touch with us.
• We still are in the midst of removing old libraries like asm3, commons-httpclient and the servlet 2.5 API, which is part of the Tomcat 6 source package.
• Want to see Azureus/Vuze in Stretch again? Packaging is almost complete but we are looking for someone who can clarify remaining licensing issues with upstream and wants to maintain the software for the foreseeable future.
• Do you have more ideas and want to get involved with the Java Team? Just send your suggestions to debian-java@lists.debian.org or chat with us on IRC at irc.debian.org, #debian-java.

Java and Friends

• The Java Team is not the only team that maintains Java software in Debian. DebianMed, DebianScience and the Android Tools Maintainers rely heavily on Java. By helping the Java Team and working together, you can improve the Java ecosystem and further the efforts of multiple other fields of endeavor all at once.

What happened in the Reproducible Builds effort between April 24th and 30th 2016. Media coverage Reproducible builds were mentioned explicitly in two talks at the Mini-DebConf in Vienna:

• Martin Michlmayr had a talk in which he presented an overview about innovations and changes in Debian in the last years. Martin expressed his disappointment that there was no talk from us in Vienna (we'll fix this at DebConf16 in Cape Town) and described the reproducible builds work as "a real innovation". His talk is very much worth seeing, whatever your current perspective, it might change your view on Debian.
• Ben Hutchings explains how Secure Boot will use signed kernels via separate signature packages and how this was designed with reproducible builds in mind.

Aspiration together with the OTF CommunityLab released their report about the Reproducible Builds summit in December 2015 in Athens. Toolchain fixes Now that the GCC development window has been opened again, the SOURCE_DATE_EPOCH patch by Dhole and Matthias Klose to address the issue timestamps_from_cpp_macros (__DATE__ / __TIME__) has been applied upstream and will be released with GCC 7. Following that Matthias Klose also has uploaded gcc-5/5.3.1-17 and gcc-6/6.1.1-1 to unstable with a backport of that SOURCE_DATE_EPOCH patch. Emmanuel Bourg uploaded maven/3.3.9-4, which uses SOURCE_DATE_EPOCH for the maven.build.timestamp. (SOURCE_DATE_EPOCH specification) Other upstream changes Alexis Bienven e submitted a patch to Sphinx which extends SOURCE_DATE_EPOCH support for copyright years in generated documentation. Packages fixed The following 12 packages have become reproducible due to changes in their build dependencies: hhvm jcsp libfann libflexdock-java libjcommon-java libswingx1-java mobile-atlas-creator not-yet-commons-ssl plexus-utils squareness svnclientadapter The following packages have became reproducible after being fixed:

tests.reproducible-builds.org

• To monitor the uptodateness of diffoscope everywhere, tests checking this on FreeBSD, NetBSD & MacPorts were added. Tests on other distributions will be added once the relevant bugs in whohas are fixed in jessie. (h01ger)

Misc. Amongst the 29 interns who will work on Debian through GSoC and Outreachy there are four who will be contributing to Reproducible Builds for Debian and Free Software. We are very glad to welcome ceridwen, Satyam Zode, Scarlett Clark and Valerie Young and look forward to working together with them the coming months (and maybe beyond)! This week's edition was written by Reiner Herrmann and Holger Levsen and reviewed by a bunch of Reproducible builds folks on IRC.

Here is my monthly update covering a large part of what I have been doing in the free software world (previously):

• Added Python 3 support to django-template-tests, a tool to perform simple static analysis on Django templates. (#1)
• Corrected my Chrome extension for the FastMail web interface to not disable the CTRL+Enter keyboard shortcut when authoring emails. (#3)
• Corrected a subtle bug in my django-staticfiles-dotd "staticfiles" library where the Content-Length HTTP header was calculated incorrectly in the presence of Unicode characters resulting in truncated output. (#2)
• Various fixes to django-slack, a library to easily post messages to the Slack group-messaging utility from projects using the Django web development framework:
  • Don't require an explicit backend import when using the Celery task queue backend. (#41)
  • Actually generate and send messages asynchronously when using the Celery backend. (#44)
• Fixed an issue with my local-debian-mirror tool where the option to disable DEP-11 mirroring wasn't working. (#1)
• Fixed an issue in django-hipchat, a library to easily post messages to the Hipchat group-messaging utility from projects using the Django web development framework where the templates were not includes when installing via PyPI. (#1)
• Created a quick-and-dirty tool to scrape a Squarespace blog and convert it to a PDF so I can read them on my Kindle e-reader. (tree)
• Updated django-keyerror a library to post exceptions to the KeyError.com error tracking service to silence an AttributeError exception in some error-reporting edge-cases. (commit)
• Suggested an improvement to the documentation for the upcoming Twitter Bootstrap version for the deprecated .hidden and .show CSS classes. (#19789)
• Submitted a documentation update to the Ansible sever configuration tool's ufw firewall module. (commit)
• I also blogged about parsing Jenkins CI output to determine job success or failure.

What happened in the reproducible builds effort between April 10th and April 16th 2016: Toolchain fixes

• Roland Rosenfeld uploaded transfig/1:3.2.5.e-6 which honors SOURCE_DATE_EPOCH. Original patch by Alexis Bienven e.
• Bill Allombert uploaded gap/4r8p3-2 which makes convert.pl honor SOURCE_DATE_EPOCH. Original patch by Jerome Benoit, duplicate patch by Dhole.
• Emmanuel Bourg uploaded ant/1.9.7-1 which makes the Javadoc task use UTF-8 as the default encoding if none was specified and SOURCE_DATE_EPOCH is set.

Antoine Beaupr suggested that gitpkg stops recording timestamps when creating upstream archives. Antoine Beaupr also pointed out that git-buildpackage diverges from the default gzip settings which is a problem for reproducibly recreating released tarballs which were made using the defaults. Alexis Bienven e submitted a patch extending sphinx SOURCE_DATE_EPOCH support to copyright year. Packages fixed The following packages have become reproducible due to changes in their build dependencies: atinject-jsr330, avis, brailleutils, charactermanaj, classycle, commons-io, commons-javaflow, commons-jci, gap-radiroot, jebl2, jetty, libcommons-el-java, libcommons-jxpath-java, libjackson-json-java, libjogl2-java, libmicroba-java, libproxool-java, libregexp-java, mobile-atlas-creator, octave-econometrics, octave-linear-algebra, octave-odepkg, octave-optiminterp, rapidsvn, remotetea, ruby-rinku, tachyon, xhtmlrenderer. The following packages became reproducible after getting fixed:

• autopkgtest/3.20.3 uploaded by Martin Pitt, original patch by Alexis Bienven e.
• fop/1:2.1-3 uploaded by Mathieu Malaterre, original patch by Alexis Bienven e.

diffoscope development Zbigniew J drzejewski-Szmek noted in #820631 that diffoscope doesn't work properly when a file contains several cpio archives. Package reviews 21 reviews have been added, 14 updated and 22 removed in this week. New issue found: timestamps_in_htm_by_gap. Chris Lamb reported 10 new FTBFS issues. Misc. The video and the slides from the talk "Reproducible builds ecosystem" at LibrePlanet 2016 have been published now. This week's edition was written by Lunar and Holger Levsen. h01ger automated the maintenance and publishing of this weekly newsletter via git.

Here is my monthly update covering a large part of what I have been doing in the free software world (previously):

• Various improvements to django-slack, a library to easily post messages to the Slack group-messaging utility from projects using the Django web development framework:
  • Added explicit support to send messages asynchronously via the Celery distributed task queue. (#29)
  • Worked with Patrick Clope to add an escapeslack template filter to ensure the correct characters for Slack's API are escaped using Django's built-in safe is too invasive. (#36)
  • Corrected an issue where custom endpoints and channel names were incompatible. (#27)
  • Overhaul of the field/option/block parsing. (49ff3c4)
  • Moved away from using a django.template.Context instance, preventing a deprecation warning. (#31)
• Added a create-folders subcommand to my tickle-me-email Getting Things Done (GTD) email toolbox to create numbered folders for the rotate "tickler" functionality. (#3)
• Wrote and released a Django template tag to collapse multiple whitespace/newline characters in order to correctly format, for example, plaintext emails that make extensive use of for-loops. These would normally require careful and fragile placement of the % for .. % and % endfor % tags. (Repo)
• Pushed a number of updates to my Strava Enhancement Suite, a Chrome extension that improves and fixes annoyances in the web interface of the Strava cycling and running tracker:
  • Fix unit conversion where the element was wrapped in an another HTML element. (#48)
  • Hide premium indicator from top-level navigation. (#45)
  • Correct matching of the "shop" link in top-level navigation and footer module. (#47 & #46)
  • Remove "premium" pages on Club pages. (#44)
• Added a security-oriented warning to Ansible's documentation regarding the behaviour if an UFW firewall application profile is added and subsequently removed. (#1740)
• Added support to my django-staticfiles-dotd "staticfiles" library which concatenates Javascript and CSS files from .d-style directories to support an arbitrary file rendering method. This allows the use of media pre-processors such as SASS within such directories. (#1)
• Corrected my Chrome extension for the FastMail web interface to correctly hook into the internal "send" mechanism. (#2)
• Moved my stravabot IRC bot to use dh-virtualenv and systemd, improving security and reliability. (1c48709)
• Updated django-pedantic-http-methods a tool to raise an exception during development when attempting to perform side effects in GET and HEAD HTTP methods to support the latest version of Django. (#1)

What happened in the reproducible builds effort between January 24th and January 30th:

Media coverage Holger Levsen was interviewed by the FOSDEM team to introduce his talk on Sunday 31st.

Toolchain fixes Jonas Smedegaard uploaded d-shlibs/0.63 which makes the order of dependencies generated by d-devlibdeps stable accross locales. Original patch by Reiner Herrmann.

diffoscope development diffoscope 48 was released on January 26th. It fixes several issues introduced by the retrieval of extra symbols from Debian debug packages. It also restores compatibility with older versions of binutils which does not support readelf --decompress.

strip-nondeterminism development strip-nondeterminism 0.015-1 was uploaded on January 27th. It fixes handling of signed JAR files which are now going to be ignored to keep the signatures intact.

Package reviews 54 reviews have been removed, 36 added and 17 updated in the previous week. 30 new FTBFS bugs have been submitted by Chris Lamb, Michael Tautschnig, Mattia Rizzolo, Tobias Frost.

Misc. Alexander Couzens and Bryan Newbold have been busy fixing more issues in OpenWrt. Version 1.6.3 of FreeBSD's package manager pkg(8) now supports SOURCE_DATE_EPOCH. Ross Karchner did a lightning talk about reproducible builds at his work place and shared the slides.

Debian LTS August was the fourth month I contributed to Debian LTS under the Freexian umbrella. In total I spent four hours working on:

• pykerberors: Fixed a regression in DLA-265-1 affecting the default parameters of checkPassword(). This resulted in DLA-265-2.
• wordpress: Craig Small updated wordpress to fix CVE-2015-2213 CVE-2015-5622 CVE-2015-5731 CVE-2015-5732 and CVE-2015-5734. I did some testing and released DLA-294-1.

Besides that I did CVE triaging of 9 CVEs to check if and how they affect oldoldstable security as part of my LTS front desk work. Debconf 15 was a great opportunity to meet some of the other LTS contributors in person and to work on some of my packages: Git-buildpackage git-buildpackage gained buildpackage-rpm based on the work by Markus Lehtonnen and merging of mock support is hopefully around the corner. Debconf had two gbp skill shares hosted by dkg and a BoF by myself. A summary is here. Integration with dgit as (discussed with Ian) looks doable and I have parts of that on my todo list as well. Among other things gbp import-orig gained a --merge-mode option so you can replace the upstream branches verbatim on your packaging branch but keep the contents of the debian/ directory. Libvirt I prepared an update for libvirt in Jessie fixing a crasher bug, QEMU error reporting. apparmor support now works out of the box in Jessie (thanks to intrigeri and Felix Geyer for that). Speaking of apparmor I learned enough at Debconf to use this now by default so we hopefully see less breackage in this area when new libvirt versions hit the archive. The bug count wen't down quiet a bit and we have a new version of virt-manager in unstable now as well. As usual I prepared the RC candidates of libvirt 1.2.19 in experimental and 1.2.19 final is now in unstable.

What happened in the reproducible builds effort this week: Toolchain fixes

• Bdale Garbee uploaded tar/1.28-1 which includes the --clamp-mtime option. Patch by Lunar.

Aur lien Jarno uploaded glibc/2.21-0experimental1 which will fix the issue were locales-all did not behave exactly like locales despite having it in the Provides field. Lunar rebased the pu/reproducible_builds branch for dpkg on top of the released 1.18.2. This made visible an issue with udebs and automatically generated debug packages. The summary from the meeting at DebConf15 between ftpmasters, dpkg mainatainers and reproducible builds folks has been posted to the revelant mailing lists. Packages fixed The following 70 packages became reproducible due to changes in their build dependencies: activemq-activeio, async-http-client, classworlds, clirr, compress-lzf, dbus-c++, felix-bundlerepository, felix-framework, felix-gogo-command, felix-gogo-runtime, felix-gogo-shell, felix-main, felix-shell-tui, felix-shell, findbugs-bcel, gco, gdebi, gecode, geronimo-ejb-3.2-spec, git-repair, gmetric4j, gs-collections, hawtbuf, hawtdispatch, jack-tools, jackson-dataformat-cbor, jackson-dataformat-yaml, jackson-module-jaxb-annotations, jmxetric, json-simple, kryo-serializers, lhapdf, libccrtp, libclaw, libcommoncpp2, libftdi1, libjboss-marshalling-java, libmimic, libphysfs, libxstream-java, limereg, maven-debian-helper, maven-filtering, maven-invoker, mochiweb, mongo-java-driver, mqtt-client, netty-3.9, openhft-chronicle-queue, openhft-compiler, openhft-lang, pavucontrol, plexus-ant-factory, plexus-archiver, plexus-bsh-factory, plexus-cdc, plexus-classworlds2, plexus-component-metadata, plexus-container-default, plexus-io, pytone, scolasync, sisu-ioc, snappy-java, spatial4j-0.4, tika, treeline, wss4j, xtalk, zshdb.

Patches submitted which have not made their way to the archive yet:

• #797027 on zyne by Chris Lamb: switch to pybuild to get rid of .pyc files.
• #797180 on python-doit by Chris Lamb: sort output when creating completion script for bash and zsh.
• #797211 on apt-dater by Chris Lamb: fix implementation of SOURCE_DATE_EPOCH.
• #797215 on getdns by Chris Lamb: fix call to dpkg-parsechangelog in debian/rules.
• #797254 on splint by Chris Lamb: support SOURCE_DATE_EPOCH for version string.
• #797296 on shiro by Chris Lamb: remove username from build string.
• #797408 on splitpatch by Reiner Herrmann: use SOURCE_DATE_EPOCH to set manpage date.
• #797410 on eigenbase-farrago by Reiner Herrmann: sets the comment style to scm-safe which tells ResourceGen that no timestamps should be included.

Chris Lamb also noticed that binaries shipped with libsilo-bin did not work. Documentation update Chris Lamb and Ximin Luo assembled a proper specification for SOURCE_DATE_EPOCH in the hope to convince more upstreams to adopt it. Thanks to Holger it is published under a non-Debian domain name. Lunar documented easiest way to solve issues with file ordering and timestamps in tarballs that came with tar/1.28-1. Some examples on how to use SOURCE_DATE_EPOCH have been improved to support systems without GNU date. reproducible.debian.net armhf is finally being tested, which also means the remote building of Debian packages finally works! This paves the way to perform the tests on even more architectures and doing variations on CPU and date. Some packages even produce the same binary Arch:all packages on different architectures (1, 2). (h01ger) Tests for FreeBSD are finally running. (h01ger) As it seems the gcc5 transition has cooled off, we schedule sid more often than testing again on amd64. (h01ger) disorderfs has been built and installed on all build nodes (amd64 and armhf). One issue related to permissions for root and unpriviliged users needs to be solved before disorderfs can be used on reproducible.debian.net. (h01ger) strip-nondeterminism Version 0.011-1 has been released on August 29th. The new version updates dh_strip_nondeterminism to match recent changes in debhelper. (Andrew Ayer) disorderfs disorderfs, the new FUSE filesystem to ease testing of filesystem-related variations, is now almost ready to be used. Version 0.2.0 adds support for extended attributes. Since then Andrew Ayer also added support to reverse directory entries instead of shuffling them, and arbitrary padding to the number of blocks used by files. Package reviews 142 reviews have been removed, 48 added and 259 updated this week. Santiago Vila renamed the not_using_dh_builddeb issue into varying_mtimes_in_data_tar_gz_or_control_tar_gz to align better with other tag names. New issue identified this week: random_order_in_python_doit_completion. 37 FTBFS issues have been reported by Chris West (Faux) and Chris Lamb. Misc. h01ger gave a talk at FrOSCon on August 23rd. Recordings are already online. These reports are being reviewed and enhanced every week by many people hanging out on #debian-reproducible. Huge thanks!

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

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. Toolchain fixes

• Kenneth J. Pronovici uploaded epydoc/3.0.1+dfsg-12 which makes class and modules ordering predictable (#795835) and fixes __repr__ so memory addresses don't appear in docs (#795826). Patches by Val Lorentz.
• Sergei Golovan uploaded erlang/1:18.0-dfsg-2 which adds support for SOURCE_DATE_EPOCH to erlc. Patch by Chris West (Faux) and Chris Lamb.
• Dmitry Shachnev uploaded sphinx/1.3.1-5 which make grammar, inventory, and JavaScript locales generation deterministic. Original patch by Val Lorentz.
• St phane Glondu uploaded ocaml/4.02.3-2 to experimental, making startup files and native packed libraries deterministic. The patch adds deterministic .file to the assembler output.
• Enrico Tassi uploaded lua-ldoc/1.4.3-3 which now pass the -d option to txt2man and add the --date option to override the current date.

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.

• #796330 on d-shlibs by Reiner Herrmann: sort with LC_ALL set to C.

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.

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. reproducible.debian.net Package pages on reproducible.debian.net 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 21^st. 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.

What happened about the reproducible builds effort for this week: Toolchain fixes

• Stephen Kitt uploaded binutils-mingw-w64/6 which enabled deterministic archives.
• Daniel Stender uploaded gamera/3.4.2-1 which removed timestamps from the documentation generator output.
• Emmanuel Bourg uploaded maven-archiver/2.6-2 which formatted the date in pom.properties with the UTC timezone.

Thanks to the reproducible-build team for running a buildd from hell. gregor herrmann

Mattia Rizzolo modified the script added last week to reschedule a package from Alioth, a reason can now be optionally specified. Holger Levsen splitted the package sets page so each set now has its own page. He also added new sets for Java packages, Haskell packages, Ruby packages, debian-installer packages, Go packages, and OCaml packages. Reiner Herrmann added locales-all to the set of packages installed in the build environment as its needed to properly identify variations due to the current locale. Holger Levsen improved the scheduling so new uploads get tested sooner. He also changed the .json output that is used by tracker.debian.org to lists FTBFS issues again but only for issues unrelated to the toolchain or our test setup. Amongst many other small fixes and additions, the graph colors should now be more friendly to red-colorblind people. The fix for pbuilder given in #677666 by Tim Landscheidt is now used. This fixed several FTBFS for OCaml packages. Work on rebuilding with different CPU has continued, a kvm-on-kvm build host has been set been set up for this purpose. debbindiff development Version 19 of debbindiff included a fix for a regression when handling info files. Version 20 fixes a bug when diffing files with many differences toward a last line with no newlines. It also now uses the proper encoding when writing the text output to a pipe, and detects info files better. Documentation update Thanks to Santiago Vila, the unneeded -depth option used with find when fixing mtimes has been removed from the examples. Package reviews 113 obsolete reviews have been removed this week while 77 has been added.
