This is my monthly summary of my free software related activities. If you re among the people who made a donation to support my work (44.52 , thanks everybody!), then you can learn how I spent your money. Otherwise it s just an interesting status update on my various projects. The Debian Administrator s Handbook Wheezy update completed. Roland and I completed the update of the Debian Administrator s Handbook for Debian 7 Wheezy. We still have some proofreading work to do but you can already enjoy the result here: http://debian-handbook.info/browse/wheezy/ Feel free to report back any problem that you discover. You can also submit us patches ready to apply if you want to go one step further. Publican contributions. The book is generated with publican and I maintain its Debian package. This month I got a release critical bug because it stopped working it turns out that the problem lied in libxml-treebuilder-perl and I thus reassigned #728885 while providing a tentative patch to the upstream author. After a few days without action from the pkg-perl team, and after having received a FTBFS bug on debian-handbook (of course publican was broken in unstable!), I prepared a fixed package myself and I uploaded it (I m still part of the pkg-perl team although I m inactive). Since I used publican heavily this month, I filed two tickets in its bugzilla. I requested a new feature in #1034836 (the possibility to keep around the former string for fuzzy strings to update), and I reported a problem with the handling of \n in PO files in #1036150. Debian France Galette update. I updated the galette package and its paypal plugin, and I deployed those on france.debian.net. It had some fixes for the reminder mails sent to members. Bylaws update. I also resumed my work on preparing new bylaws for Debian France. Sylvestre Ledru came up with a draft (with the help of a lawyer) a few months ago and I m reviewing/improving them now. The main goal is to clarify that Debian France is meant to be a Trusted Organization for the Debian project. Debian France Shop. We had the idea since a few months already but Sylvestre did the leg work to open a Debian France shop with the help of EnVenteLibre. I asked our members to prepare some CSS that better match the Debian colors and this should be fixed in a few days. The first goodies will also start to appear shortly, just in time for Christmas! Misc Debian work Distro Tracker. In the continuation of the Google Summer of Code, I asked the DSA team to setup a new virtual machine to host tracker.debian.org, an instance of Distro Tracker, the rewritten Package Tracking System. They have done their part of the job (except the mail setup), it s now waiting on me to find some time to complete some cleanups and deploy the thing. WordPress. I packaged wordpress 3.7.1 and sent a call for help on debian-mentors. I got 3 replies, I gave them some initial direction but I haven t heard back anything since. WordPress 3.8 is expected in a few days, hopefully one of the new volunteers will take care of preparing the next update. Dpkg regressions. I haven t done anything for multiple months but at least I keep running the git version of dpkg and I detected two regressions. Good to have them squashed before the upcoming 1.17.2 upload to unstable. PTS fix. I fixed some warnings that the PTS code started generating since the upgrade of its host to wheezy. They were generating some annoying backscatter mails to users of the pts@qa.debian.org bot. Ruby security update. I helped the ruby team to prepare the required security updates of ruby1.8 and ruby1.9.1 (see #730178 and #730189). This work was sponsored by Kali/Offensive Security. Smartcard setup. I bought 2 OpenPGP smartcards with a reader and I moved all my private keys on those devices (one card with the master key for signature/certification to be kept at home, one card for daily/mobile usage with the subkeys for encryption/signature/authentication). My laptop s harddrive doesn t contain any private key anymore. I have kept the required offline backup in a safe place, but in the end, my private keys are much harder to steal. I should write down my findings in another article Thanks See you next month for a new summary of my activities.

iwyu (Include What You Use) has just been accepted in Debian. This tool, based on LLVM/Clang, checks the headers of a C/C++ file. It will detect which include directives are useless, what could be improve and add comments to explain why #include are there. Let's take this C file:

#include <stdio.h>
#include <malloc.h>
#include <limits.h>

int foo(void)
fprintf(stderr, "an error\n");
return INT_MAX;

$ iwyu foo.c will return:

foo.c should remove these lines:
- #include <malloc.h> // lines 2-2

The full include-list for foo.c:
#include <limits.h> // for INT_MAX
#include <stdio.h> // for fprintf, stderr

Package on Debian

Following a thread on the Clang mailing list, I did a quick analysis of the optimization flags used to build C or C++ code. I used a rebuild result from last mid July of all Debian native packages (meaning that I don't have the log of full Java, Python or other packages without native code) and wrote a small script to count all their occurrences.
By default, deb packages uses the command "dpkg-buildflags --get CFLAGS" which will set the optimization level to -O2. However, many packages and upstream build systems do not respect such flags. On 10320 binary-only packages (in total, Debian has around 19000), the results are the following:

Optimization level	Number of occurrences	Number of packages
-O	35597	269
-Os	30849	145
-O0	13993	294
-O1	25494	809
-O2	995803	7685
-O3	106048	531
-O4	1402	16
-O5	0	0
-O6	6935	49

Since a graphic talks more than numbers (note that the Y axis is logarithmic): Disclaimer:
Some packages are using several optimization flags during the same build.
Some packages are not showing the full command line (see jessie release goal: verbose build logs)
The results might be approximate since I am basically grepping "-OX " on the log files.

This is my monthly summary of my free software related activities. If you re among the people who made a donation to support my work (47.50 , thanks everybody!), then you can learn how I spent your money. Otherwise it s just an interesting status update on my various projects. Package Tracking System There are only 2-3 weeks left in the summer of code project dedicated to rewrite the package tracking system. We have come a long way during August check it out yourself in pts.debian.net. The rewrite doesn t have all the features of the old PTS yet, but I opted to keep some of the easy and less interesting features for others to re-implement. Instead I asked Marko to work in the coming weeks on new features that will bring more value, like the possibility to have user accounts with the possibility to easily review and tweak all your subscriptions on the web, and like the possibility to subscribe to groups of packages (i.e. those managed by a team). Our main problem right now is that exim has a pretty poor default behavior of forking hundreds of processes if you get hundreds of mails (in a batch) to an address that delivers via a pipe (postfix is saner, it serializes the deliveries on pipes). The new PTS is much more modular and its memory footprint is bigger (about 3 times more for the process that delivers mails, 30Mb instead of 10Mb), and in such a situation we managed to run out of memory for now we worked around the situation with an exim setting that queues mails once the load gets too high but it s a poor workaround IMO. We could obviously implement our own queue and a daemon but I d like to avoid this. So who knows how to tell exim to behave? On the positive side, Marko has gotten some feedback from people who like the new PTS and are using it daily already. And several persons have expressed their interest to work on the new codebase already. On my side, I created a package so that it s easy to deploy for derivatives. In this process, I revamped the way we manage the Django settings (for development and for production). The package is not finished yet, but it s mostly usable already. But I still want to do some cleanup/refactoring in the models before others start deploying it. We must also enable South to make it possible to upgrade easily afterwards. DebConf 13 in Vaumarcus From August 10th to 17th, I was attending DebConf 13. It matched the only week of vacation that my wife had this summer so we went there with the whole family (that is with a 3 years old son, and 6 months old one). Thus I could not immerse myself in Debconf and missed all the nice things that happen outside of the talk rooms. I picked 3-4 interesting talks per day and I spent the rest with my family. On the positive side, I was pleased that my wife could meet (or at least see) some other Debian people. She knows quite a few (of you) by name because I have been telling her Debian stories for years now Debian France Debian France sold quite some merchandise during Debconf but I didn t take care of that. It was supervised by Sylvestre Ledru but fortunately he got the help of multiple persons, both to bring everything there, to sell it, and to bring back the rest. The good news of the month is that the upstream author of galette published a new version with all the features that we ordered him a few months ago. We send now automatic reminders to members who must renew their subscription, we have automatic update of our accounting books (in a ledger file in a git repository) when we people donate or pay their subscription via the paypal form on our website. I was so pleased to finally have this that I took some hours to finalize the packaging of galette, so that it could be uploaded to Debian. It s now waiting in the NEW queue. I also spent multiple hours to write the python script that is executed by galette and that updates the accounting files. Misc Debian stuff Debian Packaging. I did two uploads of logidee-tools to fix bugs #718671 and #718836. I created a package for Dolibarr a PHP-based CRM and ERP software (it doesn t do accounting however), it s sitting in the NEW queue for almost a month already. I forwarded #719000 to the upstream Publican developers. I filed #720393 to request a new upstream version of libphp-mailer. git-multimail. After its deployment on Alioth last month, Niels Thykier reported me a case where it lead to bounces, I filed this as a new upstream ticket and in fact I fixed it myself a few days after. I got the fixed version installed on Alioth. dpkg. I investigated why the the automatic builds of dpkg were no longer happening and asked Michael Prokop if he could install a newer version of gettext in the build chroot. He told me that he would need a backport for that so I asked Santiago Vila if he was willing to provide it and he kindly accepted. A few days after, the package was in backports and I m now again running the latest dpkg out of git thanks to the nice service provided by Michael. Misc discussions. The thread about user planets drifted into a discussion of how to avoid promotional posts on such planets and in that context someone again brought up the Debian Machine Usage Policy as a way to shut down any kind of (self-)promotional content on planet if there s money involved. This always irritates me and this time I opted to ask James Troup about the origin of that clause in the DMUP. So who is willing to work with DSA to fix the DMUP so that people stop abusing it in contexts where it doesn t make sense? I also participated in some discussions concerning dgit. I like the ideas behind the tool, but I m saddened by the behavior of Ian Jackson. I helped him to fill his gap of knowledge about new sources formats but he keeps on bashing about the 3.0 (quilt) source format both in the manual page and in the output of the program. He believes that dgit is no longer an experiment but the truth is that it s still a poorly commented Perl script doing lots of hackish things. Kali Linux Between Debconf and all, I haven t done much for Kali except a couple of fixes. There s a nice story of how I tracked a bug in live-installer on the Kali blog. That fix has been committed to Debian. I also improved live-build to include xfsprogs/jfsutils on the ISO image when you include the debian-installer (so that you don t end up in problems when you pick JFS or XFS as file systems for your installation). Thanks See you next month for a new summary of my activities.

The LLVM toolchain version 3.3 has been released a couple months ago.
Here are now the result of the rebuild of Debian archive using this version of the compiler.
Like the previous releases, we are at a bit less than 12% of packages failing (2188 packages on a total of 18854).
More warnings / errors detections have been added to the software (for example: like this defect of the C++ standard or the detection of unused linker option) causing more build failures, but, in the mean time, we fixed some issues in the Debian packages... As usual, the following image shows clearly the evolution of the build failures over time. As stated in my blog post for the release 3.2, this rebuilds prove that Clang is ready for production in term of support of the C, C++ and Objective C languages. With the performance results showed by Chandler Carruth from Google at the last Euro LLVM summit (see this video from 5:40), I believe that it is now time to report and fix the bugs in the upstream packages. I also presented this work (video) at the Debconf 13 last week in Vaumarcus (Switzerland) and I will be also presenting this work at the Linux Plumbers Conference, New Orleans. With L o Cavaille (as part of his GSOC) and Paul Tagliamonte, we are also working on providing a better automatic rebuild infrastructure for clang-built packages (and other static analyzers). More in the next few weeks. Finally, I would like to thank folks at AWS for the Debian credit and David Suarez for helping on with the Ruby segfaults.

While raw videos of the previous Debconf are available on:
http://video.debian.net/ We, at IRILL, are glad to provide a nice HTML5 interface (and flash if HTML5 videos are not available) to browse all the videos of Debconf 13:
http://www.irill.org/videos/debconf13

Due to the extremely righteous contributions of Leo and Sylvestre, we ve opted to make the name more generic (and hilarious), to make sure people understand that this will be a more general purpose tool. Cutting edge code is currently living at debile.debian.net - my debuild.me instance will soon follow when I ve got a chance to sit down with it :) Wish I was at DebConf, have a great DC, everyone!

Debian France and Debian Swiss associations are now selling products at Debconf. We are now selling

Buff		23 CHF / 18 euros
Black polo		31 CHF / 25 euros
Rugby polo		50 CHF / 40 euros
Mousepad		13 CHF / 10 euros

We have also some new hoodies.
They come in 4 colors: black, white, grey and dark blue.
With or without zip: Without zip: 44 CHF / 35 euros
With zip: 50 CHF / 40 euros With also have hats: Price: 10 CHF / 9 euros We have also the Debian umbrellas and knifes.
Photo credit Kibi For those who are at Debconf, they are for sell at the Debconf front desk from 4 to 6 and will be probably available for sell on enventelibre after the event.

As announcement on debian-devel-announce, I just uploaded java-common version 0.49. This version changes the default version of OpenJDK to version 7. That means that packages depending on default-jdk/default-jre will be now built with OpenJDK 7 (instead of the 6) and also that the java/javac commands will be providing Java 7.
I also used the opportunity of this upload to update the Java policy.

This is my monthly summary of my free software related activities. If you re among the people who made a donation to support my work (167.67 , thanks everybody!), then you can learn how I spent your money. Otherwise it s just an interesting status update on my various projects. The Debian Administrator s Handbook After the successful crowdfunding campaign, I had a bunch of rewards to ship: I subcontracted most of the job but I had to take care of the books with dedication. I also dealt regularly with books/stickers coming back to the sender (due to invalid address or people not picking up their parcels in the post-office). After the rewards, we had to take care to actually finalize the liberation of the French translation. I merged the translations we had in Git and Roland updated/translated a few strings that weren t in the original book in French. Then I have put the book online. Last but not least, I started to work on updating the English book for Debian 7 (Roland started way before me) and we have put some updated chapters up for review. Debian France Elections. After Debian France s general assembly, the new board of administrators voted the officers: I have been re-elected as President, Sylvestre continues as Treasurer but we have a new Secretary in the person of Alexandre Delano . Welcome Alexandre! I did the administrative work to register the new board/officers in the Tribunal d instance and to give access to the internal git repositories to the new members. Galette. I also did a bunch of tests on Galette s new features that Debian France ordered to the upstream author. They should all land in the next upstream release due in the next weeks. \o/ Accounting. I worked on the accounting to bring it up-to-date so that Sylvestre can pick up the work from now on. We re learning how to best use ledger for our needs. PTS rewrite I continued to spend about 12 hours a week to mentor Marko Lalic who is rewriting the Package Tracking System. I m pretty happy with the results so far so I marked him as pass for the mid-term evaluation required by Google. You can have a look at the documentation and the web interface is starting to show some content. The email interface is fully working and I have configured the real PTS to forward all mails to our test instance (pts.debian.net) so that you can use the rewritten PTS for real-life work. Mail your subscription commands to control@pts.debian.net and start using it! Thanks to the test driven development methodology we re using, we re pretty confident that it works reasonably well! I also packaged python-django-jsonfield (still in NEW) since Marko has been using this python module in his code, and filed bug #717900 on sqlite3 to raise a limit that we have hit with queries made by the PTS. Kali Linux I used the Calxeda Highbank node donated to Debian by Offensive Security to test the new -armmp kernel flavor on it. It seemed to work except for a missing network driver (filed in #717269). Misc Debian work Issues with social networks. With the move of identi.ca to pump.io, we don t have any possibility to auto-post status updates based on RSS feeds. Identi.ca s @debian account was also configured to push updates to the @debian account on twitter.com (and from there it was grabbed in the Debian page on Facebook). This is also gone so to limit the damage, I setup twitterfeed.com so that the twitter/facebook accounts continue to have updates). If you re looking for a development project, here s an area that is not well covered by free software! We need code to do what twitterfeed does and we need that code to also support pump.io. Dpkg work. It s been a long time since I last pushed some code to dpkg s git repository. I took care of reworking and merging a patch submitted by Steve Langasek to fix #716948 (an issue with dpkg-maintscript-helper rm_conffile messing with conffiles that the package no longer owns). Git mail notification. When I was still administrator of Alioth, I wrote git-commit-notice (a fork of Git s post-receive-email) and many packaging projects are using this hook script to send commit notices to mailing lists. This script has not been updated for multiple years and it started spewing warnings recently due to deprecated features in Wheezy s git. So I looked at updating it and while doing so I discovered a much better replacement with git-multimail. Thus I adapted git-commit-notice to work on top of this new script. The result has now been installed on git.debian.org (this is to be properly announced in the next DeveloperNews). Misc work. I packaged sql-ledger 3.0.5-1, forwarded #714739 on publican, and I participated in discussions to move the French Debian planets to planet.debian.org. Thanks See you next month for a new summary of my activities.

This is my monthly summary of my free software related activities. If you re among the people who made a donation to support my work (106.39 , thanks everybody!), then you can learn how I spent your money. Otherwise it s just an interesting status update on my various projects. Debian France I handled some subscriptions that we collected during Solutions Linux at the end of last month and I also worked on updating the accounts in preparation of our annual general assembly. As the current president, I wrote a moral assessment of the organization and I helped Sylvestre Ledru (the treasurer) to prepare an overview of our financial situation (which is rather good). The plan for this general assembly included the renewal of 6 of our 9 board members so I tried to motivate some persons to candidate and I m pretty happy to see that we managed to have 9 candidates for 6 seats, a real election for once. And as usual, I updated Galette to version 0.7.4.2 and I filed a couple of tickets (#621, #622). Debian Package Tracking System We re getting close to one month of work on the Google Summer of Code Project that rewrites the Package Tracking System. On average I spent a good 1h30 per day on reviewing the code, giving my feedback, and preparing the user stories for the next iteration, plus a 2 hour meeting each Wednesday afternoon. This is more than I expected but at I m rather happy with the result so far. We have a live test instance updated each week (after the end of the iteration) at pts.debian.net. The web interface is empty because the bulk of the work has been spent on the email interface for now, but it s now feature complete and already has seen some improvements compared to the current implementation (fixing #340863 for example). You can interact with it by sending mails to control@pts.debian.net. The Debian Administrator s Handbook The fundraising for the liberation of the original book in French met its initial target very quickly and we added new targets with supplementary rewards (more ebook from Eyrolles, donation to Debian). All the supplementary targets were met, although the last one took until the last day! Thanks to all the supporters, we now have a French translation of the Debian Administrator s Handbook which is free and we have collected about 2700 EUR for Debian. Debian Packaging I got a couple of release critical bug reports that I had to fix:

• #713636: cpputest FTBFS due to -Werror. Dropped -Werror in Debian and submitted the patch upstream.
• #713527: logidee-tools FTBFS due to reorganizations in the TeXLive meta-packages. Fixed the (build-)dependencies.
• #713947: multiple security issues in WordPress. Packaged new upstream version 3.5.2 into unstable and wheezy-security (and Yves-Alexis Perez took care of squeeze-security).

And trying to anticipate future issues, I filed an upstream ticket on feed2omb (#33) to see whether upstream had plans to support the new pump.io API that identi.ca is supposed to use soonish. Kali Linux I filed a couple of Debian bugs: #711866 to request a new upstream version of w3af in Debian, #711044 to report a missing dependency in LSB meta-informations of the vsftpd init script. I worked on packaging passing-the-hash. Basically this is a fork of several software just to override some NTLM authentication functions. In some cases, I managed to avoid the fork by transforming the patches in LD_PRELOAD libraries that override the specific symbol of the patched functions. Among the forked software, there was winexe which wasn t packaged yet. So I packaged it but we quickly ran into some segfaults (which was already reported to upstream since a few months). I investigated the problem and prepared a patch. It has been submitted to upstream and merged. Thanks See you next month for a new summary of my activities.

In parallel of my work on the LLVM Debian/Ubuntu nightly packages, I uploaded a couple months ago the same packages for the stable releases of the LLVM toolchain. By toolchain, this means LLVM + Clang + Clang extra tools + compiler-rt + polly + LLDB.
Previously, they were packaged as separate source packages. Making the maintenance harder and, especially, limiting the packaging of LLDB and polly. Currently, we have in the archive:

• LLVM toolchain 3.2 (note that LLDB is disabled from this release).
• LLVM toolchain 3.3
• LLVM toolchain snapshot (3.4)

For the 3.2 release, I am planning to focus on RC bug fixes.
The 3.3 and snapshot releases will get the feature improvements.
llvm-default will point to the 3.3 release once it builds on all architectures and it reached testing aka Jessie (probably during summer).

After setting an automatic code coverage tool, I just plugged an automatic scan-build on the LLVM toolchain trunk: http://buildd-clang.debian.net/scan-build/ Note that:

• polly is currently not analyzed. I had to disable the build until the new version of cloog is available.
• compiler-rt is not analyzed because it does not respect the CC/CXX argument to use the clang built locally [1]. Not sure it is a bug here.

This work is done through the Debian/LLVM jenkins instance.
The report is updated twice a day.
The scan-build/clang used to produce the report is the one published on http://llvm.org/apt/. That means that a new feature/fix done on scan-build will appear only about a day after on report. As a side effect, it tests automatically the packages distributed on llvm.org/apt/. For a project of this size, the number of reported errors / warnings is pretty low. At time of writing, only 329 errors are reported and many of them are in generated code (AttrDump.inc and LLDBWrapPython.cpp for example) or in unit tests. [1]

A week after the Euro LLVM conference, I am glad to share the results I presented and discussed during the event. 1) Parallel building infrastructure using clang instead of gcc Based on the work that Alexander Pashaliyski and I did during the GSoC 2012, we are now able to automatically rebuild each package uploaded in Unstable transparently. Results are published here:
http://buildd-clang.debian.net/
This provides a quick and easy way to any Debian contributors or upstream packaged in Debian to check how the package behaves with clang.
For Debian Developer and maintainer, a per maintainer view is also provided. This will list all packages maintained by a Debian packager. My page as example Here is an example of the list of package:
And an example of package failing:
At time of writing, most of the packages in unstable have been rebuilt (16 % are remaining). However, due to resource constraints, only amd64 packages are built. Contact me if you have resources to share for other architectures. Thanks to Paul Wise, the PTS (Debian package tracking system) proposes a link to the clang build logs (failing or not). A repository will be automatically updated with the results of these builds (once I find the time to get into buildd). 2) clang-built repository
Thanks to the Amazon Cloud, with our new DPL (Debian Project Leader), Lucas Nussbaum, we rebuilt unstable last April and published it at the following address:

deb http://clang.debian.net/repository-2013-04-07/ unstable-clang main

This allows some cool stuff like:

$ echo "deb http://clang.debian.net/repository-2013-04-07/ unstable-clang main">>/etc/apt/sources.list
$ apt-get update
$ apt-get install coreutils/unstable-clang
$ ls
$ awk

Note that this repository was only one-shoot and does not get updated. Quality of the binary produced (performance and size) can be tested thanks to this repository. Feedbacks are welcome!

Lately, I have been working on providing nightly packages of the whole LLVM toolchain.
With the help of folks from Intel, Google and Apple, I am happy to announce the publication of these packages:
http://llvm.org/apt/ Built through a Jenkins instance (http://llvm-jenkins.debian.net/), packages for Debian wheezy and Unstable and Ubuntu quantal, precise and raring are created twice a day. 3.2 and 3.3 llvm-toolchain packages are currently waiting in the Debian NEW queue. More information on the LLVM blog.
