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.

Lunar: Reproducible builds: week 3 in Stretch cycle

What happened about the reproducible builds effort for this week: Toolchain fixes Tomasz Buchert submitted a patch to fix the currently overzealous package-contains-timestamped-gzip warning. Daniel Kahn Gillmor identified #588746 as a source of unreproducibility for packages using python-support. Packages fixed The following 57 packages became reproducible due to changes in their build dependencies: antlr-maven-plugin, aspectj-maven-plugin, build-helper-maven-plugin, clirr-maven-plugin, clojure-maven-plugin, cobertura-maven-plugin, coinor-ipopt, disruptor, doxia-maven-plugin, exec-maven-plugin, gcc-arm-none-eabi, greekocr4gamera, haskell-swish, jarjar-maven-plugin, javacc-maven-plugin, jetty8, latexml, libcgi-application-perl, libnet-ssleay-perl, libtest-yaml-valid-perl, libwiki-toolkit-perl, libwww-csrf-perl, mate-menu, maven-antrun-extended-plugin, maven-antrun-plugin, maven-archiver, maven-bundle-plugin, maven-clean-plugin, maven-compiler-plugin, maven-ear-plugin, maven-install-plugin, maven-invoker-plugin, maven-jar-plugin, maven-javadoc-plugin, maven-processor-plugin, maven-project-info-reports-plugin, maven-replacer-plugin, maven-resources-plugin, maven-shade-plugin, maven-site-plugin, maven-source-plugin, maven-stapler-plugin, modello-maven-plugin1.4, modello-maven-plugin, munge-maven-plugin, ocaml-bitstring, ocr4gamera, plexus-maven-plugin, properties-maven-plugin, ruby-magic, ruby-mocha, sisu-maven-plugin, syncache, vdk2, wvstreams, xml-maven-plugin, xmlbeans-maven-plugin. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues but not all of them: Ben Hutchings also improved and merged several changes submitted by Lunar to linux. Currently untested because in contrib: reproducible.debian.net
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.

Lunar: Reproducible builds: first week in Stretch cycle

Debian Jessie has been released on April 25th, 2015. This has opened the Stretch development cycle. Reactions to the idea of making Debian build reproducibly have been pretty enthusiastic. As the pace is now likely to be even faster, let's see if we can keep everyone up-to-date on the developments. Before the release of Jessie The story goes back a long way but a formal announcement to the project has only been sent in February 2015. Since then, too much work has happened to make a complete report, but to give some highlights: Lunar did a pretty improvised lightning talk during the Mini-DebConf in Lyon. This past week It seems changes were pilling behind the curtains given the amount of activity that happened in just one week. Toolchain fixes We also rebased the experimental version of debhelper twice to merge the latest set of changes. Lunar submitted a patch to add a -creation-date to genisoimage. Reiner Herrmann opened #783938 to request making -notimestamp the default behavior for javadoc. Juan Picca submitted a patch to add a --use-date flag to texi2html. Packages fixed The following packages became reproducible due to changes of their build dependencies: apport, batctl, cil, commons-math3, devscripts, disruptor, ehcache, ftphs, gtk2hs-buildtools, haskell-abstract-deque, haskell-abstract-par, haskell-acid-state, haskell-adjunctions, haskell-aeson, haskell-aeson-pretty, haskell-alut, haskell-ansi-terminal, haskell-async, haskell-attoparsec, haskell-augeas, haskell-auto-update, haskell-binary-conduit, haskell-hscurses, jsch, ledgersmb, libapache2-mod-auth-mellon, libarchive-tar-wrapper-perl, libbusiness-onlinepayment-payflowpro-perl, libcapture-tiny-perl, libchi-perl, libcommons-codec-java, libconfig-model-itself-perl, libconfig-model-tester-perl, libcpan-perl-releases-perl, libcrypt-unixcrypt-perl, libdatetime-timezone-perl, libdbd-firebird-perl, libdbix-class-resultset-recursiveupdate-perl, libdbix-profile-perl, libdevel-cover-perl, libdevel-ptkdb-perl, libfile-tail-perl, libfinance-quote-perl, libformat-human-bytes-perl, libgtk2-perl, libhibernate-validator-java, libimage-exiftool-perl, libjson-perl, liblinux-prctl-perl, liblog-any-perl, libmail-imapclient-perl, libmocked-perl, libmodule-build-xsutil-perl, libmodule-extractuse-perl, libmodule-signature-perl, libmoosex-simpleconfig-perl, libmoox-handlesvia-perl, libnet-frame-layer-ipv6-perl, libnet-openssh-perl, libnumber-format-perl, libobject-id-perl, libpackage-pkg-perl, libpdf-fdf-simple-perl, libpod-webserver-perl, libpoe-component-pubsub-perl, libregexp-grammars-perl, libreply-perl, libscalar-defer-perl, libsereal-encoder-perl, libspreadsheet-read-perl, libspring-java, libsql-abstract-more-perl, libsvn-class-perl, libtemplate-plugin-gravatar-perl, libterm-progressbar-perl, libterm-shellui-perl, libtest-dir-perl, libtest-log4perl-perl, libtext-context-eitherside-perl, libtime-warp-perl, libtree-simple-perl, libwww-shorten-simple-perl, libwx-perl-processstream-perl, libxml-filter-xslt-perl, libxml-writer-string-perl, libyaml-tiny-perl, mupen64plus-core, nmap, openssl, pkg-perl-tools, quodlibet, r-cran-rjags, r-cran-rjson, r-cran-sn, r-cran-statmod, ruby-nokogiri, sezpoz, skksearch, slurm-llnl, stellarium. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues but not all of them: Patches submitted which did not make their way to the archive yet: Improvements to reproducible.debian.net Mattia Rizzolo has been working on compressing logs using gzip to save disk space. The web server would uncompress them on-the-fly for clients which does not accept gzip content. Mattia Rizzolo worked on a new page listing various breakage: missing or bad debbindiff output, missing build logs, unavailable build dependencies. Holger Levsen added a new execution environment to run debbindiff using dependencies from testing. This is required for packages built with GHC as the compiler only understands interfaces built by the same version. debbindiff development Version 17 has been uploaded to unstable. It now supports comparing ISO9660 images, dictzip files and should compare identical files much faster. Documentation update Various small updates and fixes to the pages about PDF produced by LaTeX, DVI produced by LaTeX, static libraries, Javadoc, PE binaries, and Epydoc. Package reviews Known issues have been tagged when known to be deterministic as some might unfortunately not show up on every single build. For example, two new issues have been identified by building with one timezone in April and one in May. RD and help2man add current month and year to the documentation they are producing. 1162 packages have been removed and 774 have been added in the past week. Most of them are the work of proper automated investigation done by Chris West. Summer of code Finally, we learned that both akira and Dhole were accepted for this Google Summer of Code. Let's welcome them! They have until May 25th before coding officialy begins. Now is the good time to help them feel more comfortable by sharing all these little bits of knowledge on how Debian works.

Reinhard Tartler: ffmpeg-uploaded

Finally ffmpeg version 0.svn20080206-9 was uploaded to unstable and is currently waiting to get out of NEW . Special thanks go out to Fabian Greffrath, for testing, reviewing and pushing me, to L oc Minier, for his thoughts on the package renaming and handling of potential unstripped replacement packages and Darren Salt for his work on the debian/rules file. This upload is targeted lenny. Highlights of that upload include:
  • introduction of ffmpeg-doc 438369
  • build flavors (read more below)
  • renaming of the source package to ffmpeg-debian
  • DEB_BUILD_OPTIONS=noopt now compiles the package with -O0 (and works!)
  • ffmpeg-config has been removed. please port your packages to use pkg-config instead, cf. 487917 and 487922.
As for the build flavors: The debian/rules file was refactored so that flavors can easily be added. The flavors are architecture specific. All architectures support a static and a dynamic flavor. The following architectures support the following flavors:
  • i386: cmov (an i686 optimized flavor using the cmov instruction)
  • powerpc: altivec (requires G4 or better)
  • sparc: vis (uses v9 instructions)
If you are interested how we manage these build flavors, have a look at our debian/rules file. I remember that this was recently discussed on debian-devel at some point. Anyway, if you need/want additional flavors, please file wishlist bugs.

Martin F. Krafft: Alternative, innovative search engines

These days (and for quite a while now), the populace equates "search" with Google. If you're like me, you'll also use alternatives. For instance, I've been quite happy with the clustered sorting provided by Clusty, which produces pretty good search results, but it isn't the fastest of all. Also, Eurekster's Swicki technology looks promising, and I am currently investigating whether it could make a good search platform for the Debian project. What do you use as alternatives to Google? What I am after aren't answers like "Yahoo" or "A9", but rather more innovative search approaches. The days of index searches and even "Page Rank" are over, IMHO. What's next? Let's hear it, please! NP: Proto-Kaw / Before Became After Update: Fabian Greffrath pointed me to Metager2, which is a meta search engine (meaning it lets others do the search), which also inspects the pages in the search result set and thus promises better quality of the results. I could not yet find more technical details except that it's Linux/Python-based. It seems to be rather centred on German contents, and the way it displays linked pages in the search results consumes too much screen estate for me. Update: Steve McIntyre contributed Trexy, which is also a meta engine that records your previous searches or lets you profit from other people's search "trails". I am not a big fan of meta searches, since those are really good at screwing up the sorting order by the engines they use, but I might try this one.
