Lunar: Reproducible builds: week 8 in Stretch cycle

What happened about the reproducible builds effort this week: Toolchain fixes Andreas Henriksson has improved Johannes Schauer initial patch for pbuilder adding support for build profiles. Packages fixed The following 12 packages became reproducible due to changes in their build dependencies: collabtive, eric, file-rc, form-history-control, freehep-chartableconverter-plugin , jenkins-winstone, junit, librelaxng-datatype-java, libwildmagic, lightbeam, puppet-lint, tabble. 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 Bugs with the ftbfs usertag are now visible on the bug graphs. This explain the recent spike. (h01ger) Andreas Beckmann suggested a way to test building packages using the funny paths that one can get when they contain the full Debian package version string. debbindiff development Lunar started an important refactoring introducing abstactions for containers and files in order to make file type identification more flexible, enabling fuzzy matching, and allowing parallel processing. Documentation update Ximin Luo detailed the proposal to standardize environment variables to pass a reference source date to tools that needs one (e.g. documentation generator). Package reviews 41 obsolete reviews have been removed, 168 added and 36 updated this week. Some more issues affecting packages failing to build from source have been identified. Meetings Minutes have been posted for Tuesday June 16th meeting. The next meeting is scheduled Tuesday June 23rd at 17:00 UTC. Presentations Lunar presented the project in French during Pas Sage en Seine in Paris. Video and slides are available.

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.
