Lunar: Reproducible builds: week 33 in Stretch cycle

What happened in the reproducible builds effort between December 6th and December 12th: Toolchain fixes Reiner Herrmann rebased our experimental version of doxygen on version 1.8.9.1-6. Chris Lamb submitted a patch to make the manpages generated by ruby-ronn reproducible by using the locale-agnostic %Y-%m-%d for the dates. Daniel Kahn Gillmor took another shot at the issue of source path captured in DWARF symbols. A patch has been sent for review by GCC upstream to add the ability to read an environment variable with -fdebug-prefix-map. Packages fixed The following 24 packages have become reproducible due to changes in their build dependencies: gkeyfile-sharp, gprbuild, graphmonkey, gthumb, haskell-yi-language, ion, jackson-databind, jackson-dataformat-smile, jackson-dataformat-xml, jnr-ffi, libcommons-net-java, libproxy, maven-shared-utils, monodevelop-database, mydumper, ndesk-dbus, nini, notify-sharp, pixz, protozero, python-rtslib-fb, slurm-llnl, taglib-sharp, tomboy-latex. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues, but not all of them: These uploads might have fixed reproducibility issues but could not be tested yet: Patches submitted which have not made their way to the archive yet: reproducible.debian.net Files created with diffoscope now have diffoscope in their name instead debbindiff. (h01ger) Hostnames of first and second build node are now recorded and shown in the build history. (Mattia Rizzolo) Exchanges have started with F-Droid developers to better understand what would be required to test F-Droid applications. (h01ger) A first small set of Fedora 23 packages is now also being tested while development on a new framework for testing RPMs in general has begun. A new Jenkins job has been added to set up to mock, the build system used by Fedora. Another new job takes care of testing RPMs from Fedora 23 on x86_64. So far only 151 packages from the buildsys-build group are tested (currently all unreproducible), but the plan is to build all 17,000 source packages in Fedora 23 and rawhide. The page presenting the results should also soon be improved. (h01ger, Dhiru Kholia) For Arch Linux, all 2223 packages from the extra repository will also be tested from now on. Packages in extra" are tested every four weeks, while those from core every week. Statistics are now displayed alongside the results. (h01ger) jenkins.debian.net has been updated to jenkins-job-builder version 1.3.0. Many job configurations have been simplified and refactored using features of the new version. This was another milestone for the jenkins.debian.org migration. (Phil Hands, h01ger) diffoscope development Chris Lamb announced try.diffoscope.org: an online service that runs diffoscope on user provided files. Screenshot of try.diffoscope.org Improvements are welcome. The application is licensed under the AGPLv3. On diffoscope itself, most pending patches have now been merged. Expect a release soon! Most of the code implementing parallel processing has been polished. Sadly, unpacking archive is CPU-bound in most cases, so the current thread-only implementation does not offer much gain on big packages. More work is still require to also add concurrent processes. Documentation update Ximin Luo has started to write a specification for buildinfo files that could become a larger platform than the limited set of features that were thought so far for Debian .buildinfo. Package reviews 113 reviews have been removed, 111 added and 56 updated in the previous week. 42 new FTBFS bugs were opened by Chris Lamb and Niko Tyni. New issues identified this week: timestamps_in_documentation_generated_by_docbook_dbtimestamp, timestamps_in_sym_l_files_generated_by_malaga, timestamps_in_edj_files_generated_by_edje_cc. Misc. Chris Lamb presented reproducible builds at skroutz.gr.

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 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.

Lunar: Reproducible builds: week 25 in Stretch cycle

What happened in the reproducible builds effort this week: Toolchain fixes Niko Tyni wrote a new patch adding support for SOURCE_DATE_EPOCH in Pod::Man. This would complement or replace the previously implemented POD_MAN_DATE environment variable in a more generic way. Niko Tyni proposed a fix to prevent mtime variation in directories due to debhelper usage of cp --parents -p. Packages fixed The following 119 packages became reproducible due to changes in their build dependencies: aac-tactics, aafigure, apgdiff, bin-prot, boxbackup, calendar, camlmix, cconv, cdist, cl-asdf, cli-common, cluster-glue, cppo, cvs, esdl, ess, faucc, fauhdlc, fbcat, flex-old, freetennis, ftgl, gap, ghc, git-cola, globus-authz-callout-error, globus-authz, globus-callout, globus-common, globus-ftp-client, globus-ftp-control, globus-gass-cache, globus-gass-copy, globus-gass-transfer, globus-gram-client, globus-gram-job-manager-callout-error, globus-gram-protocol, globus-gridmap-callout-error, globus-gsi-callback, globus-gsi-cert-utils, globus-gsi-credential, globus-gsi-openssl-error, globus-gsi-proxy-core, globus-gsi-proxy-ssl, globus-gsi-sysconfig, globus-gss-assist, globus-gssapi-error, globus-gssapi-gsi, globus-net-manager, globus-openssl-module, globus-rsl, globus-scheduler-event-generator, globus-xio-gridftp-driver, globus-xio-gsi-driver, globus-xio, gnome-control-center, grml2usb, grub, guilt, hgview, htmlcxx, hwloc, imms, kde-l10n, keystone, kimwitu++, kimwitu-doc, kmod, krb5, laby, ledger, libcrypto++, libopendbx, libsyncml, libwps, lprng-doc, madwimax, maria, mediawiki-math, menhir, misery, monotone-viz, morse, mpfr4, obus, ocaml-csv, ocaml-reins, ocamldsort, ocp-indent, openscenegraph, opensp, optcomp, opus, otags, pa-bench, pa-ounit, pa-test, parmap, pcaputils, perl-cross-debian, prooftree, pyfits, pywavelets, pywbem, rpy, signify, siscone, swtchart, tipa, typerep, tyxml, unison2.32.52, unison2.40.102, unison, uuidm, variantslib, zipios++, zlibc, zope-maildrophost. The following packages became reproducible after getting fixed: Packages which could not be tested: Some uploads fixed some reproducibility issues but not all of them: Patches submitted which have not made their way to the archive yet: Lunar reported that test strings depend on default character encoding of the build system in ongl. reproducible.debian.net The 189 packages composing the Arch Linux core repository are now being tested. No packages are currently reproducible, but most of the time the difference is limited to metadata. This has already gained some interest in the Arch Linux community. An explicit log message is now visible when a build has been killed due to the 12 hours timeout. (h01ger) Remote build setup has been made more robust and self maintenance has been further improved. (h01ger) The minimum age for rescheduling of already tested amd64 packages has been lowered from 14 to 7 days, thanks to the increase of hardware resources sponsored by ProfitBricks last week. (h01ger) diffoscope development diffoscope version 37 has been released on October 15th. It adds support for two new file formats (CBFS images and Debian .dsc files). After proposing the required changes to TLSH, fuzzy hashes are now computed incrementally. This will avoid reading entire files in memory which caused problems for large packages. New tests have been added for the command-line interface. More character encoding issues have been fixed. Malformed md5sums will now be compared as binary files instead of making diffoscope crash amongst several other minor fixes. Version 38 was released two days later to fix the versioned dependency on python3-tlsh. strip-nondeterminism development strip-nondeterminism version 0.013-1 has been uploaded to the archive. It fixes an issue with nonconformant PNG files with trailing garbage reported by Roland Rosenfeld. disorderfs development disorderfs version 0.4.1-1 is a stop-gap release that will disable lock propagation, unless --share-locks=yes is specified, as it still is affected by unidentified issues. Documentation update Lunar has been busy creating a proper website for reproducible-builds.org that would be a common location for news, documentation, and tools for all free software projects working on reproducible builds. It's not yet ready to be published, but it's surely getting there. Homepage of the future reproducible-builds.org website Who's involved? page of the future reproducible-builds.org website Package reviews 103 reviews have been removed, 394 added and 29 updated this week. 72 FTBFS issues were reported by Chris West and Niko Tyni. New issues: random_order_in_static_libraries, random_order_in_md5sums.

Lunar: Reproducible builds: week 19 in Stretch cycle

What happened in the reproducible builds effort this week: Toolchain fixes Dmitry Shachnev uploaded sphinx/1.3.1-6 with improved patches from Val Lorentz. Chris Lamb submitted a patch for ibus-table which makes the output of ibus-table-createdb deterministic. Niko Tyni wrote a patch to make libmodule-build-perl linking order deterministic. Santiago Vila has been leading discussions on the best way to fix timestamps coming from Gettext POT files. Packages fixed The following 35 packages became reproducible due to changes in their build dependencies: apache-log4j2, dctrl-tools, dms, gitit, gnubik, isrcsubmit, mailutils, normaliz, oaklisp, octave-fpl, octave-specfun, octave-vrml, opencolorio, openvdb, pescetti, php-guzzlehttp, proofgeneral, pyblosxom, pyopencl, pyqi, python-expyriment, python-flask-httpauth, python-mzml, python-simpy, python-tidylib, reactive-streams, scmxx, shared-mime-info, sikuli, siproxd, srtp, tachyon, tcltk-defaults, urjtag, velvet. The following packages became reproducible after getting fixed: The package is not in yet in unstable, but linux/4.2-1~exp1 is now reproducible! Kudos to Ben Hutchings, and most fixes are already merged upstream. 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 Some bugs that prevented packages to build successfully in the remote builders have been fixed. (h01ger) Two more amd64 build jobs have been removed from the Jenkins host in favor of six more on the new remote nodes. (h01ger) The munin graphs currently looks fine, so more amd64 jobs will probably be added in the next week. diffoscope development Version 32 of diffoscope has been released on September 3rd with the following new features: It also fixes many bugs. Head over to the changelog for the full list. Version 33 was released the day after to fix a bug introduced in the packaging. Documentation update Chris Lamb blessed the SOURCE_DATE_EPOCH specification with the version number 1.0 . Lunar documented how the .file assembler directive can help with random filenames in debug symbols. Package reviews 235 reviews have been removed, 84 added and 277 updated this week. 29 new FTBFS bugs were filled by Chris Lamb, Chris West (Faux), Daniel Stender, and Niko Tyni. New issues identified this week: random_order_in_ibus_table_createdb_output, random_order_in_antlr_output, nondetermistic_link_order_in_module_build, and timestamps_in_tex_documents. Misc. Thanks to Dhole and Thomas Vincent, the talk held at DebConf15 now has subtitles! Void Linux started to merge changes to make packages produced by xbps reproducible.

Axel Beckert: German-written Debian Package Management Book

Thursday was our big day: After more than 2.5 years of working in the hidden, ups and downs, Frank Hofmann and myself were able to announce the availability of our book project Debian Package Management under a free license (Creative Commons Attribution ShareAlike 4.0 International License, short CC BY-SA 4.0 ) during a Lightning Talk at DebConf15 in Heidelberg. This became possible because we found Onyx Neon, a publishing company which is specialised on books with contents under free licenses. Its founder does not only have a faible for Perl but also for Debian. (Since the question already came up: We also thought about self-publishing, e.g. via Lulu or Epubli and it would have been our fallback solution , but we prefer the professionalism and services of a real publisher. I m though happy to share what I found out about self-publishing in the past few months.) The source code of the book is written in the AsciiDoc format and available on GitHub. The book is still work in progress. But if you want, you can already build an e-book out of the publically available source code: 
sudo apt-get install asciidoc dblatex git
git clone git://github.com/dpmb/dpmb.git
cd dpmb
make
(Works fine on Debian 7 Wheezy, Debian 8 Jessie and Ubuntu 14.04 LTS Trusty. Does not work on Ubuntu 12.04 LTS Precise.) If you find an error in the book, please file an issue on GitHub. If you also know how to fix the error, please for the Git repository on GitHub, fix the error in your Git repository and file a pull request. (The first pull request already happenend and has been applied.) Initially there will be only a German written issue as e-book (at least in HTML, PDF and EPUB formats, maybe also KF8/MOBI and EPUB3) and at some point in the future also as printed book at Onyx Neon. But we re also planning a translation to English as well as a Debian package. If your want to get informed when we publish a printed book, a translation or an official e-book release, please subscribe to one of our mailing lists: There s one in German and one in English.

Lunar: Reproducible builds: week 13 in Stretch cycle

What happened in the reproducible builds effort this week: Toolchain fixes akira uploaded a new version of doxygen in the experimental reproducible repository incorporating upstream patch for SOURCE_DATE_EPOCH, and now producing timezone independent timestamps. Dhole updated Peter De Wachter's patch on ghostscript to use SOURCE_DATE_EPOCH and use UTC as a timezone. A modified package is now being experimented. Packages fixed The following 14 packages became reproducible due to changes in their build dependencies: bino, cfengine2, fwknop, gnome-software, jnr-constants, libextractor, libgtop2, maven-compiler-plugin, mk-configure, nanoc, octave-splines, octave-symbolic, riece, vdr-plugin-infosatepg. 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 identified as failing to build from source with no bugs filed and older than 10 days are scheduled more often now (except in experimental). (h01ger) Package reviews 178 obsolete reviews have been removed, 59 added and 122 updated this week. New issue identified this week: random_order_in_ruby_rdoc_indices. 18 new bugs for packages failing to build from sources have been reported by Chris West (Faux), and h01ger.

Lunar: Reproducible builds: week 5 in Stretch cycle

What happened about the reproducible builds effort for this week: Toolchain fixes Uploads that should help other packages: Patch submitted for toolchain issues: Some discussions have been started in Debian and with upstream: Packages fixed The following 8 packages became reproducible due to changes in their build dependencies: access-modifier-checker, apache-log4j2, jenkins-xstream, libsdl-perl, maven-shared-incremental, ruby-pygments.rb, ruby-wikicloth, uimaj. 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: Discussions that have been started: reproducible.debian.net Holger Levsen added two new package sets: pkg-javascript-devel and pkg-php-pear. The list of packages with and without notes are now sorted by age of the latest build. Mattia Rizzolo added support for email notifications so that maintainers can be warned when a package becomes unreproducible. Please ask Mattia or Holger or in the #debian-reproducible IRC channel if you want to be notified for your packages! strip-nondeterminism development Andrew Ayer fixed the gzip handler so that it skip adding a predetermined timestamp when there was none. Documentation update Lunar added documentation about mtimes of file extracted using unzip being timezone dependent. He also wrote a short example on how to test reproducibility. Stephen Kitt updated the documentation about timestamps in PE binaries. Documentation and scripts to perform weekly reports were published by Lunar. Package reviews 50 obsolete reviews have been removed, 51 added and 29 updated this week. Thanks Chris West and Mathieu Bridon amongst others. New identified issues: Misc. Lunar will be talking (in French) about reproducible builds at Pas Sage en Seine on June 19th, at 15:00 in Paris. Meeting will happen this Wednesday, 19:00 UTC.

Lunar: Reproducible builds: week 6 in Stretch cycle

What happened about the reproducible builds effort for this week: Presentations On May 26th,Holger Levsen presented reproducible builds in Debian at CCC Berlin for the Datengarten 52. The presentation was in German and the slides in English. Audio and video recordings are available. Toolchain fixes Niels Thykier fixed the experimental support for the automatic creation of debug packages in debhelper that being tested as part of the reproducible toolchain. Lunar added to the reproducible build version of dpkg the normalization of permissions for files in control.tar. The patch has also been submitted based on the main branch. Daniel Kahn Gillmor proposed a patch to add support for externally-supplying build date to help2man. This sparkled a discussion about agreeing on a common name for an environment variable to hold the date that should be used. It seems opinions are converging on using SOURCE_DATE_UTC which would hold a ISO-8601 formatted date in UTC) (e.g. 2015-06-05T01:08:20Z). Kudos to Daniel, Brendan O'Dea, Ximin Luo for pushing this forward. Lunar proposed a patch to Tar upstream adding a --clamp-mtime option as a generic solution for timestamp variations in tarballs which might also be useful for dpkg. The option changes the behavior of --mtime to only use the time specified if the file mtime is newer than the given time. So far, upstream is not convinced that it would make a worthwhile addition to Tar, though. Daniel Kahn Gillmor reached out to the libburnia project to ask for help on how to make ISO created with xorriso reproducible. We should reward Thomas Schmitt with a model upstream trophy as he went through a thorough analysis of possible sources of variations and ways to improve the situation. Most of what is missing with the current version in Debian is available in the latest upstream version, but libisoburn in Debian needs help. Daniel backported the missing option for version 1.3.2-1.1. akira submitted a new issue to Doxygen upstream regarding the timestamps added to the generated manpages. Packages fixed The following 49 packages became reproducible due to changes in their build dependencies: activemq-protobuf, bnfc, bridge-method-injector, commons-exec, console-data, djinn, github-backup, haskell-authenticate-oauth, haskell-authenticate, haskell-blaze-builder, haskell-blaze-textual, haskell-bloomfilter, haskell-brainfuck, haskell-hspec-discover, haskell-pretty-show, haskell-unlambda, haskell-x509-util, haskelldb-hdbc-odbc, haskelldb-hdbc-postgresql, haskelldb-hdbc-sqlite3, hasktags, hedgewars, hscolour, https-everywhere, java-comment-preprocessor, jffi, jgit, jnr-ffi, jnr-netdb, jsoup, lhs2tex, libcolor-calc-perl, libfile-changenotify-perl, libpdl-io-hdf5-perl, libsvn-notify-mirror-perl, localizer, maven-enforcer, pyotherside, python-xlrd, python-xstatic-angular-bootstrap, rt-extension-calendar, ruby-builder, ruby-em-hiredis, ruby-redcloth, shellcheck, sisu-plexus, tomcat-maven-plugin, v4l2loopback, vim-latexsuite. 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: Daniel Kahn Gilmor also started discussions for emacs24 and the unsorted lists in generated .el files, the recording of a PID number in lush, and the reproducibility of ISO images in grub2. reproducible.debian.net Notifications are now sent when the build environment for a package has changed between two builds. This is a first step before automatically building the package once more. (Holger Levsen) jenkins.debian.net was upgraded to Debian Jessie. (Holger Levsen) A new variation is now being tested: $PATH. The second build will be done with a /i/capture/the/path added. (Holger Levsen) Holger Levsen with the help of Alexander Couzens wrote extra job to test the reproducibility of coreboot. Thanks James McCoy for helping with certificate issues. Mattia Rizollo made some more internal improvements. strip-nondeterminism development Andrew Ayer released strip-nondeterminism/0.008-1. This new version fixes the gzip handler so that it now skip adding a predetermined timestamp when there was none. Holger Levsen sponsored the upload. Documentation update The pages about timestamps in manpages generated by Doxygen, GHC .hi files, and Jar files have been updated to reflect their status in upstream. Markus Koschany documented an easy way to prevent Doxygen to write timestamps in HTML output. Package reviews 83 obsolete reviews have been removed, 71 added and 48 updated this week. Meetings A meeting was held on 2015-06-03. Minutes and full logs are available. It was agreed to hold such a meeting every two weeks for the time being. The time of the next meeting should be announced soon.

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.

Axel Beckert: Do we need a zsh-static package in Debian?

Dear Planet Debian, the Debian Zsh Packaging Team (consisting of Michael Prokop, Frank Terbeck, Richard Hartmann and myself) wonders if there s still a reason to build and ship a zsh-static package in Debian. There are multiple reasons: So we ask you, the Planet Debian reader:

Do you need Debian s zsh-static package? If so, please send an e-mail to us Debian Zsh Maintainers <pkg-zsh-devel@lists.alioth.debian.org> and state that you use zsh-static, and, if you want, please also state why or how you re using it. Thanks in advance! Mika, Frank, RichiH and Axel

Axel Beckert: GNU Screen 4.2.0 in Debian Experimental

About a month ago, on 20th of March, GNU Screen had its 27th anniversary. A few days ago, Amadeusz S awi ski, GNU Screen s new primary upstream maintainer, released the status quo of Screen development as version 4.2.0 (probably to distinguish it from all those 4.1.0 labeled development snapshots floating around in most Linux distributions nowadays). I did something similar and uploaded the status quo of Debian s screen package in git as 4.1.0~20120320gitdb59704-10 to Debian Sid shortly afterwards. That upload should hit Jessie soon, too, resolving the following two issues also in Testing: That way I could decouple these packaging fixes/features from the new upstream release which I uploaded to Debian Experimental for now. Testers for the 4.2.0-1 package are very welcome! Oh, and by the way, that upstream comment (or ArchLinux s according announcement) about broken backwards compatibility with attaching to running sessions started with older Screen releases doesn t affected Debian since that has been fixed in Debian already with the package which is in Wheezy. (Thanks again Julien Cristau for the patch back then!) While there are bigger long-term plans at upstream, Amadeusz is already working on the next 4.x release (probably named 4.2.1) which will likely incorporate some of the patches floating around in the Linux distributions packages. At least SuSE and Debian offered their patches explicitly for upstream inclusion. So far already two patches found in the Debian packages have been obsoleted by upstream git commits after the 4.2.0 release. Yay!

Axel Beckert: Xen: Running a Sid DomU with PyGrub on a Squeeze Dom0

I m running one Debian Sid and one Jessie (Testing) Xen guest domain on a Debian Squeeze (Oldstable) Xen 4.0 running host server. Recently I had to reboot one these virtual machines after more than a year of uptime. But the new 3.14 kernel from Debian Experimental didn t boot. Neither did 3.13 from Debian Unstable. Nor did any other kernel image newer then the 3.5-trunk (from Debian Experimental back than) work. Everytime pygrub bailed out with this error message: 
Error: (2, 'Invalid kernel', 'xc_dom_find_loader: no loader found\n')
(Yes, the parentheses and the \n were part of the error message.) After some searching on the web I found hints that this message may be caused by an unsupported compression type in the kernel image. And indeed, if I unpack the vmlinuz with the extract-vmlinux tool which is part of Linux source code (but not yet part of any binary package in Debian), and use the extract file in grub s menu.lst (which is then read by pygrub) instead, the DomU boots Linux kernel 3.14 again, even on a Squeeze-running Dom0.

Axel Beckert: PDiffs are still useful

probably just not as default. I do agree with Richi and with Michael that disabling PDiffs by default gives the big majority of Debian Testing or Unstable users a speedier package list update. I m though not sure, if disabling PDiffs by default would Additionally I want to remind you that PDiffs per se are nothing bad and should be continued to be supported: So yes, disabling PDiffs by default is probably ok, but the feature must be kept available for those who haven t 100 MBit/s fibre connection into their homes or are sitting just one hop away from the next Debian mirror (like me at work :-). Oh, and btw., for the very same reasons I m also a big fan of debdelta which is approximately the same as PDiffs, just not for package lists but for binary packages. Using debdelta I was able to speed up my download rates over EDGE to up to virtual 100 kB/s, i.e. by factor four (depending on the packages). Just imagine a LibreOffice minor update at 15 kB/s average download rate. ;-) And all these experiences were not made with a high-performance CPU but with the approximately 5 year old Intel Atom processor of my ASUS EeePC 900A. So I used PDiffs and debdelta even despite having a slight performance penalty on applying the diffs and deltas.

Axel Beckert: Showing packages newer than in archive with aptitude

I happens quite often that I install a manually built, newer version of some package on a machine. Occassionally I forget to remove it or to downgrade it to the version in the APT repo. 
$ apt-show-versions   fgrep newer
easily finds those packages. But usually when doing such a check, I want this list of packages in my aptitude TUI to have a look at the other versions of that package and to take actions. And I don t want to manually search for each of the package manually. This can be done with the following one-liner : 
# aptitude -o "Aptitude::Pkg-Display-Limit=(  apt-show-versions   fgrep newer   awk -F '[ :]' ' printf "~n ^"$1"$   " '   sed -e 's/  *$//'  )"
It uses apt-show-version s output, searches for the right packages, takes the first column and transforms it into an aptitude search pattern matching all packages whose name is exactly one of the listed packages. But this solution is quite ugly and slow. So I wondered if this is also doable with pure aptitude search patterns which likely would also be faster. And after some playing around I found the following working aptitude search term: 
~i ?any-version(!~O.) !~U !~o
This matches all packages which which are installed and which have a version which has no origin, i.e. no associated APT repository. Since this also matches all hold packages as well as all packages not available in any archive, I use !~U !~o to exclude those packages from that list again. Since nobody can remember that nor wants to type that everytime needed, I added the following alias to my setup: 
alias aptitude-newer-than-in-archive='aptitude -o "Aptitude::Pkg-Display-Limit=~i ?any-version(!~O.) !~U !~o"'
Only caveat so far: It seems to also match packages from APT repos which haven t set an Origin . This should not happen with any Debian or Ubuntu APT repository, but seems to happen occasionally with privately run APT repositories. And using ~A instead of ~O, i.e. ~i ?any-version(!~A.), does not work for this case either, despite it matches installed packages of which versions not in any available archive exist. But unfortunately aptitude seems to remember in some way if a package was in some archive in the past, so this only shows packages installed with dpkg -i, but not packages removed from e.g. unstable but with older versions still being available in stable.

Axel Beckert: Next Debian Meetup in Zurich

The first Debian meetup in Zurich last month was quite a success and I look forward to further Debian meetups in Zurich every first Tuesday of the month. The next meetup will be

on Tuesday, 2013-Dec-03 starting at 18:30 CET
at St. Gallerhof, Konradstrasse 2, 8005 Zurich Please note that this is a different location than last month. Everybody who is interested in Debian is welcome to join us. Registering is not necessary. There was also some interest in Debian meetups in other Swiss cities, namely Bern and somewhere around Lac Leman. In case you want a Debian meetup elsewhere in Switzerland, too, or if you re interested in any Debian meetup in Switzerland, feel free to join the Swiss Debian Community Mailing List and help organising other Swiss Debian meetups.

Next.
