James McCoy: Monthly FLOSS activity - 2017/09 edition

Debian devscripts Before deciding to take an indefinite hiatus from devscripts, I prepared one more upload merging various contributed patches and a bit of last minute cleanup. I also setup integration with Travis CI to hopefully catch issues sooner than "while preparing an upload", as was typically the case before. Anyone with push access to the Debian/devscripts GitHub repo can take advantage of this to test out changes, or keep the development branches up to date. In the process, I was able to make some improvements to, namely support for DEB_BUILD_PROFILES and using a separate, minimal docker image for running autopkgtests. unibilium neovim Oddly, the mips64el builds were in BD-Uninstallable state, even though luajit's buildd status showed it was built. Looking further, I noticed the libluajit-5.1 ,-dev binary packages didn't have the mips64el architecture enabled, so I asked for it to be enabled. msgpack-c There were a few packages left which would FTBFS if I uploaded msgpack-c 2.x to unstable. All of the bug reports had either trivial work arounds (i.e., forcing use of the v1 C++ API) or trivial patches. However, I didn't want to continue waiting for the packages to get fixed since I knew other people had expressed interest in the new msgpack-c. Trying to avoid making other packages insta-buggy, I NMUed autobahn-cpp with the v1 work around. That didn't go over well, partly because I didn't send a finalized "Hey, I'd like to get this done and here's my plan to NMU" email. Based on that feedback, I decided to bump the remaining bugs to "serious" instead of NMUing and upload msgpack-c. Thanks to Jonas Smedegaard for quickly integrating my proposed fix for libdata-messagepack-perl. Hopefully, upstream has some time to review the PR soon. vim subversion

Chris Lamb: Free software activities in September 2017

Here is my monthly update covering what I have been doing in the free software world in September 2017 (previous month):
Reproducible builds

Whilst anyone can inspect the source code of free software for malicious flaws, most software is distributed pre-compiled to end users. The motivation behind the Reproducible Builds effort is to allow verification that no flaws have been introduced either maliciously or accidentally during this compilation process by promising identical results are always generated from a given source, thus allowing multiple third-parties to come to a consensus on whether a build was compromised. I have generously been awarded a grant from the Core Infrastructure Initiative to fund my work in this area. This month I:
  • Published a short blog post about how to determine which packages on your system are reproducible. [...]
  • Submitted a pull request for Numpy to make the generated files reproducible. [...]
  • Provided a patch to GTK upstream to ensure the immodules.cache files are reproducible. [...]
  • Within Debian:
    • Updated, moving it to HTTPS, adding cachebusting as well as keeping the number up-to-date.
    • Submitted the following patches to fix reproducibility-related toolchain issues:
      • gdk-pixbuf: Make the output of gdk-pixbuf-query-loaders reproducible. (#875704)
      • texlive-bin: Make PDF IDs reproducible. (#874102)
    • Submitted a patch to fix a reproducibility issue in doit.
  • Categorised a large number of packages and issues in the Reproducible Builds "notes" repository.
  • Chaired our monthly IRC meeting. [...]
  • Worked on publishing our weekly reports. (#123, #124, #125, #126 & #127)

I also made the following changes to our tooling:

reproducible-check is our script to determine which packages actually installed on your system are reproducible or not.

  • Handle multi-architecture systems correctly. (#875887)
  • Use the "restricted" data file to mask transient issues. (#875861)
  • Expire the cache file after one day and base the local cache filename on the remote name. [...] [...]
I also blogged about this utility. [...]

diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues.

  • Filed an issue attempting to identify the causes behind an increased number of timeouts visible in our CI infrastructure, including running a number of benchmarks of recent versions. (#875324)
  • New features:
    • Add "binwalking" support to analyse concatenated CPIO archives such as initramfs images. (#820631).
    • Print a message if we are reading data from standard input. [...]
  • Bug fixes:
    • Loosen matching of file(1)'s output to ensure we correctly also match TTF files under file version 5.32. [...]
    • Correct references to path_apparent_size in comparators.utils.file and self.buf in diffoscope.diff. [...] [...]
  • Testing:
    • Make failing some critical flake8 tests result in a failed build. [...]
    • Check we identify all CPIO fixtures. [...]
  • Misc:
    • No need for try-assert-except block in [...]
    • Compare types with identity not equality. [...] [...]
    • Use's lazy argument interpolation. [...]
    • Remove unused imports. [...]
    • Numerous PEP8, flake8, whitespace, other cosmetic tidy-ups.


strip-nondeterminism is our tool to remove specific non-deterministic results from a completed build.

  • Log which handler processed a file. (#876140). [...]


disorderfs is our FUSE-based filesystem that deliberately introduces non-determinism into directory system calls in order to flush out reproducibility issues.

Debian My activities as the current Debian Project Leader are covered in my monthly "Bits from the DPL" email to the debian-devel-announce mailing list.
Lintian I made a large number of changes to Lintian, the static analysis tool for Debian packages. It reports on various errors, omissions and general quality-assurance issues to maintainers: I also blogged specifically about the Lintian 2.5.54 release.

Patches contributed
  • debconf: Please add a context manager to (#877096)
  • Add pronouns to ALL_STATUS_DESC. (#875128)

Russ Allbery: Free software log (July and August 2017)

I've wanted to start making one of these posts for a few months but have struggled to find the time. But it seems like a good idea, particularly since I get more done when I write down what I do, so you all get a rather belated one. This covers July and August; hopefully the September one will come closer to the end of September. Debian August was DebConf, which included a ton of Policy work thanks to Sean Whitton's energy and encouragement. During DebConf, we incorporated work from Hideki Yamane to convert Policy to reStructuredText, which has already made it far easier to maintain. (Thanks also to David Bremner for a lot of proofreading of the result.) We also did a massive bug triage and closed a ton of older bugs on which there had been no forward progress for many years. After DebConf, as expected, we flushed out various bugs in the reStructuredText conversion and build infrastructure. I fixed a variety of build and packaging issues and started doing some more formatting cleanup, including moving some footnotes to make the resulting document more readable. During July and August, partly at DebConf and partly not, I also merged wording fixes for seven bugs and proposed wording (not yet finished) for three more, as well as participated in various Policy discussions. Policy was nearly all of my Debian work over these two months, but I did upload a new version of the webauth package to build with OpenSSL 1.1 and drop transitional packages. Kerberos I still haven't decided my long-term strategy with the Kerberos packages I maintain. My personal use of Kerberos is now fairly marginal, but I still care a lot about the software and can't convince myself to give it up. This month, I started dusting off pam-krb5 in preparation for a new release. There's been an open issue for a while around defer_pwchange support in Heimdal, and I spent some time on that and tracked it down to an upstream bug in Heimdal as well as a few issues in pam-krb5. The pam-krb5 issues are now fixed in Git, but I haven't gotten any response upstream from the Heimdal bug report. I also dusted off three old Heimdal patches and submitted them as upstream merge requests and reported some more deficiencies I found in FAST support. On the pam-krb5 front, I updated the test suite for the current version of Heimdal (which changed some of the prompting) and updated the portability support code, but haven't yet pulled the trigger on a new release. Other Software I merged a couple of pull requests in podlators, one to fix various typos (thanks, Jakub Wilk) and one to change the formatting of man page references and function names to match the current Linux manual page standard (thanks, Guillem Jover). I also documented a bad interaction with line-buffered output in the Term::ANSIColor man page. Neither of these have seen a new release yet.

Paul Wise: Check All The thingS!

check-all-the-things (aka cats, Meow!) is a tool that aims to make it easy to know which tools can be used to check a directory tree and to make it easy to run those tools on the directory tree. The tree could either be a source tree or a build tree or both. It aims to check as much of the tree as possible so the output can be very verbose and have many false positives. It is not for the busy, lazy or noise intolerant. It runs the checks by matching file names and MIME types against those registered for a list of checks. Each check has a set of dependencies, flags, filename wildcards, MIME type wildcards, comments and prerequisite commands. By default it: It runs all checks for the current distro/release except: There are command-line options to customise the behaviour and automatic bash shell completion via argcomplete. There are 177 checks (including TODO ones) in 73 different categories. There are an additional 224 not-well-specified TODO items for new checks in comments. It is exceptionally easy to add new checks once one knows how to use the tool one wants to add. At this point in time it is probably not a good idea to run it in an untrusted directory tree for several reasons: The project initially started as really hacky wiki page full of commands to run. At some point I figured it was time to make this actually be maintainable and started on a project to do that. At around the same time Jakub Wilk was working on maquack to replace the wiki page. Somehow I found out about it and talked to him about it. It was vastly less hacky than my version so I ended up taking it over and continuing it under the check-all-the-things name. I polished it for the last two years and finally released it into Debian unstable during DebCamp16.

29 June 2016

Paul Wise: DebCamp16 day 6

Redirect one person contacting the Debian sysadmin and web teams to Debian user support. Review wiki RecentChanges. Usual spam reporting. Check and fix a derivatives census issue. Suggest sending the titanpad maintainence issue to a wider audience. Update check-all-the-things and copyright review tools wiki page for licensecheck/devscripts split. Ask if debian-debug could be added to Discuss more about the devscripts/licensecheck split. Yesterday I grrred at Debian perl bug #588017 that causes vulnerabilities in check-all-the-things, tried to figure out the scope of the issue and workaround all of the issues I could find. (Perls are shiny and Check All The thingS can be abbreviated as cats) Today I confirmed with the reporter (Jakub Wilk) that the patch mitigates this. Release check-all-the-things to Debian unstable (finally!!). Discuss with the borg about syncing cats to Ubuntu. Notice autoconf/automake being installed as indirect cats build-deps (via debhelper/dh-autoreconf) and poke relevant folks about this. Answer question about alioth vs LDAP.

Niels Thykier: Tor enabled MTA

As I posted earlier, I have migrated to use tor on my machine. Though I had a couple of unsolved issues back then. One of them being my Mail Transport Agent (MTA) did not support tor. A regular user might not have a lot of use for a MTA on their laptop. However, it is needed for a lot of Debian development scripts (bts, mass-bug, nmudiff), if they are to file/manipulate bugs for you. I have some requirements for my MTA I also have some non-requirements: Originally, I used postfix, which supported most of these requirements. Except: Per suggestion of Jakub Wilk, I tried msmtp, which turned out do what I wanted. The only feature I will probably miss is having a local queue, which can be rate limited. But all in all, I am quite happy with it so far. :)

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. 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 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 website  Who's involved?  page of the future 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: 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.

Gregor Herrmann: RC bugs 2015/17-29

after the release is before the release. or: long time no RC bug report. after the jessie release I spent most of my Debian time on work in the Debian Perl Group. we tried to get down the list of new upstream releases (from over 500 to currently 379; unfortunately the CPAN never sleeps), we were & still are busy preparing for the Perl 5.22 transition (e.g. we uploaded something between 300 & 400 packages to deal with Module::Build & being removed from perl core; only team-maintained packages so far), & we had a pleasant & productive sprint in Barcelona in May. & I also tried to fix some of the RC bugs in our packages which popped up over the previous months. yesterday & today I finally found some time to help with the GCC 5 transition, mostly by making QA or Non-Maintainer Uploads with patches that already were in the BTS. a big thanks especially to the team at HP which provided a couple dozens patches! & here's the list of RC bugs I've worked on in the last 3 months:

Lunar: Reproducible builds: week 11 in Stretch cycle

Debian is undertaking a huge effort to develop a reproducible builds system. I'd like to thank you for that. This could be Debian's most important project, with how badly computer security has been going.

PerniciousPunk in Reddit's Ask me anything! to Neil McGovern, DPL. What happened in the reproducible builds effort this week: Toolchain fixes More tools are getting patched to use the value of the SOURCE_DATE_EPOCH environment variable as the current time:

In the reproducible experimental toolchain which have been uploaded: Johannes Schauer followed up on making sbuild build path deterministic with several ideas. Packages fixed The following 311 packages became reproducible due to changes in their build dependencies : 4ti2, alot, angband, appstream-glib, argvalidate, armada-backlight, ascii, ask, astroquery, atheist, aubio, autorevision, awesome-extra, bibtool, boot-info-script, bpython, brian, btrfs-tools, bugs-everywhere, capnproto, cbm, ccfits, cddlib, cflow, cfourcc, cgit, chaussette, checkbox-ng, cinnamon-settings-daemon, clfswm, clipper, compton, cppcheck, crmsh, cupt, cutechess, d-itg, dahdi-tools, dapl, darnwdl, dbusada, debian-security-support, debomatic, dime, dipy, dnsruby, doctrine, drmips, dsc-statistics, dune-common, dune-istl, dune-localfunctions, easytag, ent, epr-api, esajpip, eyed3, fastjet, fatresize, fflas-ffpack, flann, flex, flint, fltk1.3, fonts-dustin, fonts-play, fonts-uralic, freecontact, freedoom, gap-guava, gap-scscp, genometools, geogebra, git-reintegrate, git-remote-bzr, git-remote-hg, gitmagic, givaro, gnash, gocr,, gprbuild, grapefruit, greed, gtkspellmm, gummiboot, gyp, heat-cfntools, herold, htp, httpfs2, i3status, imagetooth, imapcopy, imaprowl, irker, jansson, jmapviewer, jsdoc-toolkit, jwm, katarakt, khronos-opencl-man, khronos-opengl-man4, lastpass-cli, lava-coordinator, lava-tool, lavapdu, letterize, lhapdf, libam7xxx, libburn, libccrtp, libclaw, libcommoncpp2, libdaemon, libdbusmenu-qt, libdc0, libevhtp, libexosip2, libfreenect, libgwenhywfar, libhmsbeagle, libitpp, libldm, libmodbus, libmtp, libmwaw, libnfo, libpam-abl, libphysfs, libplayer, libqb, libsecret, libserial, libsidplayfp, libtime-y2038-perl, libxr, lift, linbox, linthesia, livestreamer, lizardfs, lmdb, log4c, logbook, lrslib, lvtk, m-tx, mailman-api, matroxset, miniupnpd, mknbi, monkeysign, mpi4py, mpmath, mpqc, mpris-remote, musicbrainzngs, network-manager, nifticlib, obfsproxy, ogre-1.9, opal, openchange, opensc, packaging-tutorial, padevchooser, pajeng, paprefs, pavumeter, pcl, pdmenu, pepper, perroquet, pgrouting, pixz, pngcheck, po4a, powerline, probabel, profitbricks-client, prosody, pstreams, pyacidobasic, pyepr, pymilter, pytest, python-amqp, python-apt, python-carrot, python-django, python-ethtool, python-mock, python-odf, python-pathtools, python-pskc, python-psutil, python-pypump, python-repoze.tm2, python-repoze.what, qdjango, qpid-proton, qsapecng, radare2, reclass, repsnapper, resource-agents, rgain, rttool, ruby-aggregate, ruby-albino, ruby-archive-tar-minitar, ruby-bcat, ruby-blankslate, ruby-coffee-script, ruby-colored, ruby-dbd-mysql, ruby-dbd-odbc, ruby-dbd-pg, ruby-dbd-sqlite3, ruby-dbi, ruby-dirty-memoize, ruby-encryptor, ruby-erubis, ruby-fast-xs, ruby-fusefs, ruby-gd, ruby-git, ruby-globalhotkeys, ruby-god, ruby-hike, ruby-hmac, ruby-integration, ruby-jnunemaker-matchy, ruby-memoize, ruby-merb-core, ruby-merb-haml, ruby-merb-helpers, ruby-metaid, ruby-mina, ruby-net-irc, ruby-net-netrc, ruby-odbc, ruby-ole, ruby-packet, ruby-parseconfig, ruby-platform, ruby-plist, ruby-popen4, ruby-rchardet, ruby-romkan, ruby-ronn, ruby-rubyforge, ruby-rubytorrent, ruby-samuel, ruby-shoulda-matchers, ruby-sourcify, ruby-test-spec, ruby-validatable, ruby-wirble, ruby-xml-simple, ruby-zoom, rumor, rurple-ng, ryu, sam2p, scikit-learn, serd, shellex, shorewall-doc, shunit2, simbody, simplejson, smcroute, soqt, sord, spacezero, spamassassin-heatu, spamprobe, sphinxcontrib-youtube, splitpatch, sratom, stompserver, syncevolution, tgt, ticgit, tinyproxy, tor, tox, transmissionrpc, tweeper, udpcast, units-filter, viennacl, visp, vite, vmfs-tools, waffle, waitress, wavtool-pl, webkit2pdf, wfmath, wit, wreport, x11proto-input, xbae, xdg-utils, xdotool, xsystem35, yapsy, yaz. Please note that some packages in the above list are falsely reproducible. In the experimental toolchain, debhelper exported TZ=UTC and this made packages capturing the current date (without the time) reproducible in the current test environment. The following packages became reproducible after getting fixed: Ben Hutchings upstreamed several patches to fix Linux reproducibility issues which were quickly merged. Some uploads fixed some reproducibility issues but not all of them: Uploads that should fix packages not in main: Patches submitted which have not made their way to the archive yet: A new package set has been added for lua maintainers. (h01ger) now only shows reproducibility issues for unstable. Holger and Mattia worked on several bugfixes and enhancements: finished initial test setup for NetBSD, rewriting more shell scripts in Python, saving UDD requests, and more debbindiff development Reiner Herrmann fixed text comparison of files with different encoding. Documentation update Juan Picca added to the commands needed for a local test chroot installation of the locales-all package. Package reviews 286 obsolete reviews have been removed, 278 added and 243 updated this week. 43 new bugs for packages failing to build from sources have been filled by Chris West (Faux), Mattia Rizzolo, and h01ger. The following new issues have been added: timestamps_in_manpages_generated_by_ronn, timestamps_in_documentation_generated_by_org_mode, and timestamps_in_pdf_generated_by_matplotlib. Misc. Reiner Herrmann has submitted patches for OpenWrt. Chris Lamb cleaned up some code and removed cruft in the misc.git repository. Mattia Rizzolo updated the prebuilder script to match what is currently done on

Lunar: Reproducible builds: week 10 in Stretch cycle

What happened about the reproducible builds effort this week: Media coverage Daniel Stender published an English translation of the article which originally appeared in Linux Magazin in Admin Magazine. Toolchain fixes Fixes landed in the Debian archive: Lunar submitted to Debian the patch already sent upstream adding a --clamp-mtime option to tar. Patches have been submitted to add support for SOURCE_DATE_EPOCH to txt2man (Reiner Herrmann), epydoc (Reiner Herrmann), GCC (Dhole), and Doxygen (akira). Dhole uploaded a new experimental debhelper to the reproducible repository which exports SOURCE_DATE_EPOCH. As part of the experiment, the patch also sets TZ to UTC which should help with most timezone issues. It might still be problematic for some packages which would change their settings based on this. Mattia Rizzolo sent upstream a patch originally written by Lunar to make the generate-id() function be deterministic in libxslt. While that patch was quickly rejected by upstream, Andrew Ayer came up with a much better one which sadly could have some performance impact. Daniel Veillard replied with another patch that should be deterministic in most cases without needing extra data structures. It's impact is currently being investigated by retesting packages on akira added a new option to sbuild for configuring the path in which packages are built. This will be needed for the srebuild script. Niko Tyni asked Perl upstream about it using the __DATE__ and __TIME__ C processor macros. Packages fixed The following 143 packages became reproducible due to changes in their build dependencies: alot, argvalidate, astroquery, blender, bpython, brian, calibre, cfourcc, chaussette, checkbox-ng, cloc, configshell, daisy-player, dipy, dnsruby, dput-ng, dsc-statistics, eliom, emacspeak, freeipmi, geant321, gpick, grapefruit, heat-cfntools, imagetooth, jansson, jmapviewer, lava-tool, libhtml-lint-perl, libtime-y2038-perl, lift, lua-ldoc, luarocks, mailman-api, matroxset, maven-hpi-plugin, mknbi, mpi4py, mpmath, msnlib, munkres, musicbrainzngs, nova, pecomato, pgrouting, pngcheck, powerline, profitbricks-client, pyepr, pylibssh2, pylogsparser, pystemmer, pytest, python-amqp, python-apt, python-carrot, python-crypto, python-darts.lib.utils.lru, python-demgengeo, python-graph, python-mock, python-musicbrainz2, python-pathtools, python-pskc, python-psutil, python-pypump, python-repoze.sphinx.autointerface, python-repoze.tm2, python-repoze.what-plugins, python-repoze.what, python-repoze.who-plugins, python-xstatic-term.js, reclass, resource-agents, rgain, rttool, ruby-aggregate, ruby-archive-tar-minitar, ruby-bcat, ruby-blankslate, ruby-coffee-script, ruby-colored, ruby-dbd-mysql, ruby-dbd-odbc, ruby-dbd-pg, ruby-dbd-sqlite3, ruby-dbi, ruby-dirty-memoize, ruby-encryptor, ruby-erubis, ruby-fast-xs, ruby-fusefs, ruby-gd, ruby-git, ruby-globalhotkeys, ruby-god, ruby-hike, ruby-hmac, ruby-integration, ruby-ipaddress, ruby-jnunemaker-matchy, ruby-memoize, ruby-merb-core, ruby-merb-haml, ruby-merb-helpers, ruby-metaid, ruby-mina, ruby-net-irc, ruby-net-netrc, ruby-odbc, ruby-packet, ruby-parseconfig, ruby-platform, ruby-plist, ruby-popen4, ruby-rchardet, ruby-romkan, ruby-rubyforge, ruby-rubytorrent, ruby-samuel, ruby-shoulda-matchers, ruby-sourcify, ruby-test-spec, ruby-validatable, ruby-wirble, ruby-xml-simple, ruby-zoom, ryu, simplejson, spamassassin-heatu, speaklater, stompserver, syncevolution, syncmaildir, thin, ticgit, tox, transmissionrpc, vdr-plugin-xine, waitress, whereami, xlsx2csv, zathura. 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: A new package set for the X Strike Force has been added. (h01ger) Bugs tagged with locale are now visible in the statistics. (h01ger) Some work has been done add tests for NetBSD. (h01ger) Many changes by Mattia Rizzolo have been merged on the whole infrastructure: debbindiff development Version 26 has been released on June 28th fixing the comparison of files of unknown format. (Lunar) A missing dependency identified in python-rpm affecting debbindiff installation without recommended packages was promptly fixed by Michal iha . Lunar also started a massive code rearchitecture to enhance code reuse and enable new features. Nothing visible yet, though. Documentation update josch and Mattia Rizzolo documented how to reschedule packages from Alioth. Package reviews 142 obsolete reviews have been removed, 344 added and 107 updated this week. Chris West (Faux) filled 13 new bugs for packages failing to build from sources. The following new issues have been added: snapshot_placeholder_replaced_with_timestamp_in_pom_properties, different_encoding, timestamps_in_documentation_generated_by_org_mode and timestamps_in_pdf_generated_by_matplotlib.

Lunar: Reproducible builds: week 9 in Stretch cycle

What happened about the reproducible builds effort this week: Toolchain fixes Norbert Preining uploaded texinfo/6.0.0.dfsg.1-2 which makes texinfo indices reproducible. Original patch by Chris Lamb. Lunar submitted recently rebased patches to make the file order of files inside .deb stable. akira filled #789843 to make tex4ht stop printing timestamps in its HTML output by default. Dhole wrote a patch for xutils-dev to prevent timestamps when creating gzip compresed files. Reiner Herrmann sent a follow-up patch for wheel to use UTC as timezone when outputing timestamps. Mattia Rizzolo started a discussion regarding the failure to build from source of subversion when -Wdate-time is added to CPPFLAGS which happens when asking dpkg-buildflags to use the reproducible profile. SWIG errors out because it doesn't recognize the aforementioned flag. Trying to get the .buildinfo specification to more definitive state, Lunar started a discussion on storing the checksums of the binary package used in dpkg status database. akira discovered while proposing a fix for simgrid that CMake internal command to create tarballs would record a timestamp in the gzip header. A way to prevent it is to use the GZIP environment variable to ask gzip not to store timestamps, but this will soon become unsupported. It's up for discussion if the best place to fix the problem would be to fix it for all CMake users at once. Infrastructure-related work Andreas Henriksson did a delayed NMU upload of pbuilder which adds minimal support for build profiles and includes several fixes from Mattia Rizzolo affecting reproducibility tests. Neils Thykier uploaded lintian which both raises the severity of package-contains-timestamped-gzip and avoids false positives for this tag (thanks to Tomasz Buchert). Petter Reinholdtsen filled #789761 suggesting that how-can-i-help should prompt its users about fixing reproducibility issues. Packages fixed The following packages became reproducible due to changes in their build dependencies: autorun4linuxcd, libwildmagic, lifelines, plexus-i18n, texlive-base, texlive-extra, texlive-lang. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues but not all of them: Untested uploaded as they are not in main: Patches submitted which have not made their way to the archive yet: debbindiff development debbindiff/23 includes a few bugfixes by Helmut Grohne that result in a significant speedup (especially on larger files). It used to exhibit the quadratic time string concatenation antipattern. Version 24 was released on June 23rd in a hurry to fix an undefined variable introduced in the previous version. (Reiner Herrmann) debbindiff now has a test suite! It is written using the PyTest framework (thanks Isis Lovecruft for the suggestion). The current focus has been on the comparators, and we are now at 93% of code coverage for these modules. Several problems were identified and fixed in the process: paths appearing in output of javap, readelf, objdump, zipinfo, unsqusahfs; useless MD5 checksum and last modified date in javap output; bad handling of charsets in PO files; the destination path for gzip compressed files not ending in .gz; only metadata of cpio archives were actually compared. stat output was further trimmed to make directory comparison more useful. Having the test suite enabled a refactoring of how comparators were written, switching from a forest of differences to a single tree. This helped removing dust from the oldest parts of the code. Together with some other small changes, version 25 was released on June 27th. A follow up release was made the next day to fix a hole in the test suite and the resulting unidentified leftover from the comparator refactoring. (Lunar) Documentation update Ximin Luo improved code examples for some proposed environment variables for reference timestamps. Dhole added an example on how to fix timestamps C pre-processor macros by adding a way to set the build date externally. akira documented her fix for tex4ht timestamps. Package reviews 94 obsolete reviews have been removed, 330 added and 153 updated this week. Hats off for Chris West (Faux) who investigated many fail to build from source issues and reported the relevant bugs. Slight improvements were made to the scripts for editing the review database, edit-notes and clean-notes. (Mattia Rizzolo) Meetings A meeting was held on June 23rd. Minutes are available. The next meeting will happen on Tuesday 2015-07-07 at 17:00 UTC. Misc. The Linux Foundation announced that it was funding the work of Lunar and h01ger on reproducible builds in Debian and other distributions. This was further relayed in a Bits from Debian blog post.

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: 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.

Jakub Wilk: Joys of East Asian encodings

In i18nspector I try to support all the encodings that were blessed by gettext, but it turns out to be more difficult than I anticipated:
$ roundtrip()   c=$(echo $1   iconv -t $2); printf '%s -> %s -> %s\n' $1 $c $(echo $c   iconv -f "$2");  
$ roundtrip   EUC-JP
  -> \ -> \
$ roundtrip   SHIFT_JIS
  -> \ ->  
$ roundtrip   JOHAB
  -> \ ->  
Now let's do the same in Python:
$ python3 -q
>>> roundtrip = lambda s, e: print('%s -> %s -> %s' % (s, s.encode(e).decode('ASCII', 'replace'), s.encode(e).decode(e)))
>>> roundtrip(' ', 'EUC-JP')
  -> \ -> \
>>> roundtrip(' ', 'SHIFT_JIS')
  -> \ -> \
>>> roundtrip(' ', 'JOHAB')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 1, in <lambda>
UnicodeEncodeError: 'johab' codec can't encode character '\u20a9' in position 0: illegal multibyte sequence
So is 0x5C a backslash or a yen/won sign? Or both? And what if 0x5C could be a second byte of a two-byte character? What could possibly go wrong?

Jakub Wilk: More spell-checking

Have you ever wanted to use Lintian's spell-checker against arbitrary files? Now you can do it with spellintian:
$ zrun spellintian --picky /usr/share/doc/RFC/best-current-practice/rfc*
/tmp/0qgJD1Xa1Y-rfc1917.txt: amoung -> among
/tmp/kvZtN435CE-rfc3155.txt: transfered -> transferred
/tmp/o093khYE09-rfc3481.txt: unecessary -> unnecessary
/tmp/4P0ux2cZWK-rfc6365.txt: charater -> character
mwic (Misspelled Words In Context) takes a different approach. It uses classic spell-checking libraries (via Enchant), but it groups misspellings and shows them in their contexts. That way you can quickly filter out false-positives, which are very common in technical texts, using visual grep:
$ zrun mwic /usr/share/doc/debian/social-contract.txt.gz
