Simon Josefsson: Laptop Buying Advice?

My current Lenovo X201 laptop has been with me for over four years. I ve been looking at new laptop models over the years thinking that I should upgrade. Every time, after checking performance numbers, I ve always reached the conclusion that it is not worth it. The most performant Intel Broadwell processor is the the Core i7 5600U and it is only about 1.5 times the performance of my current Intel Core i7 620M. Meanwhile disk performance has increased more rapidly, but changing the disk on a laptop is usually simple. Two years ago I upgraded to the Samsung 840 Pro 256GB disk, and this year I swapped that for the Samsung 850 Pro 1TB, and both have been good investments. Recently my laptop usage patterns have changed slightly, and instead of carrying one laptop around, I have decided to aim for multiple semi-permanent laptops at different locations, coupled with a mobile device that right now is just my phone. The X201 will remain one of my normal work machines. What remains is to decide on a new laptop, and there begins the fun. My requirements are relatively easy to summarize. The laptop will run a GNU/Linux distribution like Debian, so it has to work well with it. I ve decided that my preferred CPU is the Intel Core i7 5600U. The screen size, keyboard and mouse is mostly irrelevant as I never work longer periods of time directly on the laptop. Even though the laptop will be semi-permanent, I know there will be times when I take it with me. Thus it has to be as lightweight as possible. If there would be significant advantages in going with a heavier laptop, I might reconsider this, but as far as I can see the only advantage with a heavier machine is bigger/better screen, keyboard (all of which I find irrelevant) and maximum memory capacity (which I would find useful, but not enough of an argument for me). The sub-1.5kg laptops with the 5600U CPU on the market that I have found are:
Lenovo X250 1.42kg 12.5 1366 768
Lenovo X1 Carbon (3rd gen) 1.44kg 14 2560 1440
Dell Latitude E7250 1.25kg 12.5 1366 768
Dell XPS 13 1.26kg 13.3 3200 1800
HP EliteBook Folio 1040 G2 1.49kg 14 1920 1080
HP EliteBook Revolve 810 G3 1.4kg 11.6 1366 768
I find it interesting that Lenovo, Dell and HP each have two models that meets my 5600U/sub-1.5kg criteria. Regarding screen, possibly there exists models with other screen resolutions. The XPS 13, HP 810 and X1 models I looked had touch screens, the others did not. As screen is not important to me, I didn t evaluate this further. I think all of them would suffice, and there are only subtle differences. All except the XPS 13 can be connected to peripherals using one cable, which I find convenient to avoid a cable mess. All of them have DisplayPort, but HP uses DisplayPort Standard and the rest uses miniDP. The E7250 and X1 have HDMI output. The X250 boosts a 15-pin VGA connector, none of the others have it I m not sure if that is a advantage or disadvantage these days. All of them have 2 USB v3.0 ports except the E7250 which has 3 ports. The HP 1040, XPS 13 and X1 Carbon do not have RJ45 Ethernet connectors, which is a significant disadvantage to me. Ironically, only the smallest one of these, the HP 810, can be memory upgraded to 12GB with the others being stuck at 8GB. HP and the E7250 supports NFC, although Debian support is not certain. The E7250 and X250 have a smartcard reader, and again, Debian support is not certain. The X1, X250 and 810 have a 3G/4G card. Right now, I m leaning towards rejecting the XPS 13, X1 and HP 1040 because of lack of RJ45 ethernet port. That leaves me with the E7250, X250 and the 810. Of these, the E7250 seems like the winner: lightest, 1 extra USB port, HDMI, NFC, SmartCard-reader. However, it has no 3G/4G-card and no memory upgrade options. Looking for compatibility problems, it seems you have to be careful to not end up with the Dell Wireless card and the E7250 appears to come in a docking and non-docking variant but I m not sure what that means. Are there other models I should consider? Other thoughts?

Dirk Eddelbuettel: drat Tutorial: Publishing a package

Introduction The drat package was released earlier this month, and described in a first blog post. I received some helpful feedback about what works and what doesn't. For example, Jenny Bryan pointed out that I was not making a clear enough distinction between the role of using drat to publish code, and using drat to receive/install code. Very fair point, and somewhat tricky as R aims to blur the line between being a user and developer of statistical analyses, and hence packages. Many of us are both. Both the main point is well taken, and this note aims to clarify this issue a little by focusing on the former. Another point make by Jenny concerns the double use of repository. And indeed, I conflated repository (in the sense of a GitHub code repository) with repository for a package store used by a package manager. The former, a GitHub repository, is something we use to implement a personal drat with: A GitHub repository happens to be uniquely identifiable just by its account name, and given an (optional) gh-pages branch also offers a stable and performant webserver we use to deliver packages for R. A (personal) code repository on the other hand is something we implement somewhere---possibly via drat which supports local directories, possibly on a network share, as well as anywhere web-accessible, e.g. via a GitHub repository. It is a little confusing, but I will aim to make the distinction clearer.

Just once: Setting up a drat repository So let us for the remainder of this post assume the role of a code publisher. Assume you have a package you would like to make available, which may not be on CRAN and for which you would like to make installation by others easier via drat. The example below will use an interim version of drat which I pushed out yesterday (after fixing a bug noticed when pushing the very new RcppAPT package). For the following, all we assume (apart from having a package to publish) is that you have a drat directory setup within your git / GitHub repository. This is not an onerous restriction. First off, you don't have to use git or GitHub to publish via drat: local file stores and other web servers work just as well (and are documented). GitHub simply makes it easiest. Second, bootstrapping one is trivial: just fork my drat GitHub repository and then create a local clone of the fork. There is one additional requirement: you need a gh-pages branch. Using the fork-and-clone approach ensures this. Otherwise, if you know your way around git you already know how to create a gh-pages branch. Enough of the prerequisities. And on towards real fun. Let's ensure we are in the gh-pages branch:
edd@max:~/git/drat(master)$ git checkout gh-pages
Switched to branch 'gh-pages'
Your branch is up-to-date with 'origin/gh-pages'.
edd@max:~/git/drat(gh-pages)$ 

Publish: Run one drat command to insert a package Now, let us assume you have a package to publish. In my case this was version 0.0.1.2 of drat itself as it contains a fix for the very command I am showing here. So if you want to run this, ensure you have this version of drat as the CRAN version is currently behind at release 0.0.1 (though I plan to correct that in the next few days). To publish an R package into a code repository created via drat running on a drat GitHub repository, just run insertPackage(packagefile) which we show here with the optional commit=TRUE. The path to the package can be absolute are relative; the easists is often to go up one directory from the sources to where R CMD build ... has created the package file.
edd@max:~/git$ Rscript -e 'library(drat); insertPackage("drat_0.0.1.2.tar.gz", commit=TRUE)'
[gh-pages 0d2093a] adding drat_0.0.1.2.tar.gz to drat

edd@max:~/git$ 
You can equally well run this as insertPackage("drat_0.0.1.2.tar.gz"), then inspect the repo and only then run the git commands add, commit and push. Also note that future versions of drat will most likely support git operations directly by relying on the very promising git2r package. But this just affect package internals, the user-facing call of e.g. insertPackage("drat_0.0.1.2.tar.gz", commit=TRUE) will remain unchanged. And in a nutshell that really is all there is to it. With the newly drat-ed package pushed to your GitHub repository with a single function call), it is available via the automatically-provided gh-pages webserver access to anyone in the world. All they need to do is to point R's package management code (which is built into R itself and used for e.g._ CRAN and BioConductor R package repositories) to the new repo---and that is also just a single drat command. We showed this in the first blog post and may expand on it again in a follow-up. So in summary, that really is all there is to it. After a one-time setup / ensuring you are on the gh-pages branch, all it takes is a single function call from the drat package to publish your package to your drat GitHub repository.

Niels Thykier: Partial rewrite of lintian s reporting setup

I had the mixed pleasure of doing a partial rewrite of lintian s reporting framework. It started as a problem with generating the graphs, which turned out to be not enough memory . On the plus side, I am actually quite pleased with the end result. I managed to scope-creep myself quite a bit and I ended up getting rid of a lot of old issues. The major changes in summary: There are also some nice minor features : As you can probably tell, I am quite pleased with the end result. The reporting framework lacks behind in development, since it just sits there and takes care of itself . Also with the complete lack of testing, it also suffers from the if it is not broken, then do not fix it paradigm (because we will not notice if we broke until it is too late). Of course, I managed to break the setup a couple of times in the process. However, a bonus feature of the reporting setup is that if you break it, it simply leaves an outdated report on the website. Anyway, enjoy. :)

Lucas Nussbaum: Some email organization tips and tricks

I d like to share a few tips that were useful to strengthen my personal email organization. Most of what follows is probably not very new nor special, but hey, let s document it anyway. Many people have an inbox folder that just grow over time. It s actually similar to a twitter or RSS feed (except they probably agree that they are supposed to read more of their email feed ). When I send an email to them, it sometimes happen that they don t notice it, if the email arrives at a bad time. Of course, as long as they don t receive too many emails, and there aren t too many people relying on them, it might just work. But from time to time, it s super-painful for those interacting with them, when they miss an email and they need to be pinged again. So let s try not to be like them. :-) Tip #1: do Inbox Zero (or your own variant of it) Inbox Zero is an email management methodology inspired from David Allen s Getting Things Done book. It s best described in this video. The idea is to turn one s Inbox into an area that is only temporary storage, where every email will get processed at some point. Processing can mean deleting an email, archiving it, doing the action described in the email (and replying to it), etc. Put differently, it basically means implementing the Getting Things Done workflow on one s email. Tip #1.1: archive everything One of the time-consuming decisions in the original GTD workflow is to decide whether something should be eliminated (deleted) or stored for reference. Given that disk space is quite cheap, it s much easier to never decide about that, and just archive everything (by duplicating the email to an archive folder when it is received). To retrieve archived emails when needed, I then use notmuch within mutt to easily search through recent (< 2 year) archives. I use archivemail to archive older email in compressed mboxes from time to time, and grepmail to search through those mboxes when needed. I don t archive most Debian mailing lists though, as they are easy to fetch from master.d.o with the following script:
#!/bin/sh
rsync -vP master.debian.org:~debian/*/*$1/*$1.$ 2:-$(date +%Y%m) * .
Then I can fetch a specific list archive with getlist devel 201502, or a set of archives with e.g. getlist devel 2014, or the current month with e.g. getlist devel. Note that to use grepmail on XZ-compressed archives, you need libmail-mbox-messageparser-perl version 1.5002-3 (only in unstable I was using a locally-patched version for ages, but finally made a patch last week, which Gregor kindly uploaded). Tip #1.2: split your inbox (Yes, this one looks obvious but I m always surprised at how many people don t do that.) Like me, you probably receive various kinds of emails: Splitting those into separate folders has several advantages: I ve seen some people splitting their inbox into too many folders. There s not much point in having a per-sender folder organization (unless there s really a recurring flow of emails from a specific person), as it increases the risk of missing an email. I use procmail to organize my email into folders. I know that there are several more modern alternatives, but I haven t looked at them since procmail does the job for me. Resulting organization I use one folder for my day-job email, one for my DPL email, one for all other email directed or Cced to me. Then, I have a few folders for automated notifications of stuff. My Debian mailing list folders are auto-managed by procmail s $MATCH:
:0:
 * ^X-Mailing-List: <.*@lists\.debian\.org>
 * ^X-Mailing-List: <debian-\/[^@]*
 .ml.debian.$MATCH/
Some other mailing lists are in they separate folders, and there s a catch-all folder for the remaining ones. Ah, and since I use feed2imap, I have folders for the RSS/Atom feeds I follow. I have two different commands to start mutt. One only shows a restricted number of (important) folders. The other one shows the full list of (non-empty) folders. This is a good trick to avoid spending time reading email when I am supposed to do something more important. :) As for many people probably, my own organization is loosely based on GTD and Inbox Zero. It sometimes happen that some emails stay in my Inbox for several days or weeks, but I very rarely have more than 20 or 30 emails in one of my main inbox folders. I also do reviews of the whole content of my main inbox folders once or twice a week, to ensure that I did not miss an email that could be acted on quickly. A last trick is that I have a special folder replies, where procmail copies emails that are replies to a mail I sent, but which do not Cc me. That s useful to work-around Debian s no Cc on reply to mailing list posts policy. I receive email using offlineimap (over SSH to my mail server), and send it using nullmailer (through a SSH tunnel). The main advantage of offlineimap over using IMAP directly in mutt is that using IMAP to a remote server feels much more sluggish. Another advantage is that I only need SSH access to get my full email setup to work. Tip #2: tracking sent emails Two recurring needs I had was: I developed a short script to address that. It scans the content of my Sent maildir and my archive maildirs, and, for each email address I use, displays (see example output in README) the list of emails sent with this address (one email per line). It also detects if an email was replied to ( R column after the date), and abbreviates common parts in email addresses (debian-project@lists.debian.org becomes d-project@l.d.o). It also generates a temporary maildir with symlinks to all emails, so that I can just open the maildir if needed.

Clint Adams: Copyleft licenses are oppressing someone

I go to a party, carrying two expensive bottles of liquor that I have acquired from faraway lands. The hosts of the party provide a variety of liquors, snacks, and mixers. Some neuro guy shows up, looks around, feels guilty, says that he should have brought something. His friend shows up, bearing hot food. The neuro guy decides to contribute $7 to the purchase of food since he didn't bring anything. The friend then proceeds to charge us each $7. No one else demands money for any of the other things being share and consumed by everyone. The hosts do not retroactively charge a cover fee for entrance to the house. No one else offers to pay anyone for anything. The neuro guy attempts to wash some dishes before leaving, but is stopped by the hosts, because he is a guest.

Sergio Talens-Oliag: Retooling

I haven't blogged for a long time, but I've decided that I'm going to try to write again, at least about technical stuff. My plan was to blog about the projects I've been working on lately, the main one being the setup of the latest version of Kolab with the systems we already have at work, but I'll do that on the next days. Today I'm just going to make a list of the tools I use on a daily basis and my plans to start using additional ones in the near future. Shells, Terminals and Text Editors I do almost all my work on Z Shell sessions running inside tmux; for terminal emulation I use gnome-terminal on X, VX ConnectBot on Android systems and iTerm2 on Mac OS X. For text editing I've been using Vim for a long time (even on Mobile devices) and while I'm aware I don't know half of the things it can do, what I know is good enough for my day to day needs. In the past I also used Emacs as a programming editor and my main tool to write HTML, SGML and XML, but since I haven't really needed an IDE for a long time and I mainly use Lightweight Markup Languages I haven't used it for a long time (I briefly tried to use Org mode, but for some reason I ended up leaving it). Documentation formats and tools Since a long time ago I've been an advocate of Lightweight Markup Languages; I started to use LaTeX and Lout, then moved to SGML/XML formats (LinuxDoc and DocBook) and finally moved to plain text based formats. I started using Wiki formats (parsewiki) and soon moved to reStructuredText; I also use other markup languages like Markdown (for this blog, aka ikiwiki) and tried MultiMarkdown to replace reStructuredText for general use, but as I never liked Markdown syntax I didn't liked an extended version of it. While I've been using ReStructuredText for a long time, I recently found Asciidoctor and the Asciidoc format and I guess I'll be using it instead of rst whenever I can (I still need to try the slide backends and conversions to ODT, but if that works I guess I'll write all my new documents using Asciidoc). Programming languages I'm not a developer, but I read and patch a lot of free software code written on a lot of different programming languages (I wouldn't be able to write whole programs on most of them, but thanks to Stack Overflow I'm usually able to fix what I need). Anyway, I'm able to program in some languages; I write a lot of shell scripts and I go for Python and C when I need something more complicated. On the near future I plan to read about javascript programming and nodejs (I'll probably need it at work) and I already started looking at Haskell (I guess it was time to learn about functional programming and after reading about it, it looks like haskell is the way to go for me). Version Control For a long time I've been a Subversion user, at least for my own projects, but seems that everything has moved to git now and I finally started to use it (I even opened a github account) and plan to move all my personal subversion repositories at home and at work to git, including the move of all my debian packages from svn-buildpackage to git-buildpackage. Further Reading With the previous plans in mind, I've started reading a couple of interesting books: Now I just need to get enough time to finish reading them ... ;)

Rapha&#235;l Hertzog: Freexian s report about Debian Long Term Support, January 2015

Like each month, here comes a report about the work of paid contributors to Debian LTS. Individual reports In January, 48 work hours have been equally split among 4 paid contributors. Their reports are available: Evolution of the situation During the last month, the number of paid work hours has made a noticeable jump: we re now at 58 hours per month. At this rate, we would need 3 more months to reach our minimal goal of funding the equivalent of a half-time position. Unfortunately, the number of new sponsors actually in the process is not likely to be enough to have a similar raise next month. So, as usual, we are looking for more sponsors. In terms of security updates waiting to be handled, the situation looks a bit worse than last month: the dla-needed.txt file lists 37 packages awaiting an update (7 more than last month), the list of open vulnerabilities in Squeeze shows about 63 affected packages in total (7 more than last month). The increase is not too worrying, but the waiting time before an issue is dealt with is sometimes more problematic. To be able to deal with all incoming issues in a timely manner, the LTS team needs more resources: some months will have more issues than usual, some issues will be longer to handle than others, etc. Thanks to our sponsors The new sponsors of the month are in bold.

John Goerzen: Reactions to Has modern Linux lost its way? and the value of simplicity

Apparently I touched a nerve with my recent post about the growing complexity of issues. There were quite a few good comments, which I ll mention here. It s provided me some clarity on the problem, in fact. I ll try to distill a few more thoughts here. The value of simplicity and predictability The best software, whether it s operating systems or anything else, is predictable. You read the documentation, or explore the interface, and you can make a logical prediction that when I do action X, the result will be Y. grep and cat are perfect examples of this. The more complex the rules in the software, the more hard it is for us to predict. It leads to bugs, and it leads to inadvertant security holes. Worse, it leads to people being unable to fix things themselves one of the key freedoms that Free Software is supposed to provide. The more complex software is, the fewer people will be able to fix it by themselves. Now, I want to clarify: I hear a lot of talk about ease of use. Gnome removes options in my print dialog box to make it easier to use. (This is why I do not use Gnome. It actually makes it harder to use, because now I have to go find some obscure way to just make the darn thing print.) A lot of people conflate ease of use with ease of learning, but in reality, I am talking about neither. I am talking about ease of analysis. The Linux command line may not have pointy-clicky icons, but at least at one time once you understood ls -l and how groups, users, and permission bits interacted, you could fairly easily conclude who had access to what on a system. Now we have a situation where the answer to this is quite unclear in terms of desktop environments (apparently some distros ship network-manager so that all users on the system share the wifi passwords they enter. A surprise, eh?) I don t mind reading a manpage to learn about something, so long as the manpage was written to inform. With this situation of dbus/cgmanager/polkit/etc, here s what it feels like. This, to me, is the crux of the problem: It feels like we are in a twisty maze, every passage looks alike, and our flashlight ran out of battieries in 2013. The manpages, to the extent they exist for things like cgmanager and polkit, describe the texture of the walls in our cavern, but don t give us a map to the cave. Therefore, we are each left to piece it together little bits at a time, but there are traps that keep moving around, so it s slow going. And it s a really big cave. Other user perceptions There are a lot of comments on the blog about this. It is clear that the problem is not specific to Debian. For instance: This stuff is really important, folks. People being able to maintain their own software, work with it themselves, etc. is one of the core reasons that Free Software exists in the first place. It is a fundamental value of our community. For decades, we have been struggling for survival, for relevance. When I started using Linux, it was both a question and an accomplishment to have a useable web browser on many platforms. (Netscape Navigator was closed source back then.) Now we have succeeded. We have GPL-licensed and BSD-licensed software running on everything from our smartphones to cars. But we are snatching defeat from the jaws of victory, because just as we are managing to remove the legal roadblocks that kept people from true mastery of their software, we are erecting technological ones that make the step into the Free Software world so much more difficult than it needs to be. We no longer have to craft Modelines for X, or compile a kernel with just the right drivers. This is progress. Our hardware is mostly auto-detected and our USB serial dongles work properly more often on Linux than on Windows. This is progress. Even our printers and scanners work pretty darn well. This is progress, too. But in the place of all these things, now we have userspace mucking it up. We have people with mysterious errors that can t be easily assisted by the elders in the community, because the elders are just as mystified. We have bugs crop up that would once have been shallow, but are now non-obvious. We are going to leave a sour taste in people s mouth, and stir repulsion instead of interest among those just checking it out. The ways out It s a nasty predicament, isn t it? What are your ways out of that cave without being eaten by a grue? Obviously the best bet is to get rid of the traps and the grues. Somehow the people that are working on this need to understand that elegance is a feature a darn important feature. Sadly I think this ship may have already sailed. Software diagnosis tools like Enrico Zini s seat-inspect idea can also help. If we have something like an ls for polkit that can reduce all the complexity to something more manageable, that s great. The next best thing is a good map good manpages, detailed logs, good error messages. If software would be more verbose about the permission errors, people could get a good clue about where to look. If manpages for software didn t just explain the cavern wall texture, but explain how this room relates to all the other nearby rooms, it would be tremendously helpful. At present, I am unsure if our problem is one of very poor documentation, or is so bad that good documentation like this is impossible because the underlying design is so complex it defies being documented in something smaller than a book (in which case, our ship has not just sailed but is taking on water). Counter-argument: progress One theme that came up often in the comments is that this is necessary for progress. To a certain extent, I buy that. I get why udev is important. I get why we want the DE software to interact well. But here s my thing: this already worked well in wheezy. Gnome, XFCE, and KDE software all could mount/unmount my drives. I am truly still unsure what problem all this solved. Yes, cloud companies have demanding requirements about security. I work for one. Making security more difficult to audit doesn t do me any favors, I can assure you. The systemd angle To my surprise, systemd came up quite often in the discussion, despite the fact that I mentioned I wasn t running systemd-sysv. It seems like the new desktop environemt ecosystem is the systemd ecosystem in a lot of people s minds. I m not certain this is justified; systemd was not my first choice, but as I said in an earlier blog post, jessie will still boot . A final note I still run Debian on all my personal boxes and I m not going to change. It does awesome things. For under $100, I built a music-playing system, with Raspberry Pis, fully synced throughout my house, using a little scripting and software. The same thing from Sonos would have cost thousands. I am passionate about this community and its values. Even when jessie releases with polkit and all the rest, I m still going to use it, because it is still a good distro from good people.

Dirk Eddelbuettel: RPushbullet 0.2.0

A new releases of the RPushbullet package (interfacing the neat Pushbullet service) arrived on CRAN today. It brings several weeks of extensions, corrections and cleanups---with key contributions by Mike Birdgeneau and Henrik Bengtsson. RPushbullet now has support for channels (a reasonably new feature upstream). Setup, initialization and tests all got improved as well. Changes are summarized below based in the extract from the NEWS.Rd file.
Changes in version 0.2.0 (2015-02-07)
  • Added support for Pushbullet 'channels' (once again thanks to Mike Birdgeneau for the initial push on this)
  • Support for pushes was solidified: proper choices of either device, email or channel should work in all cases
  • S3 methods are now properly exports (thanks to Henrik Bengtsson)
  • File transfer mode has been improved / corrected (thanks to Mike Birdgeneau)
  • The regression test suite was expanded and robustified
  • This NEWS file was added. Better late than never.
Courtesy of CRANberries, there is also a diffstat report for this release. More details about the package are at the RPushbullet webpage and the RPushbullet GitHub repo.

Carl Chenet: Backup Checker 1.0, the fully automated backup checker

Follow me on Identi.ca or Twitter or Diaspora*diaspora-banner Backup Checker is the new name of the Brebis project. Backup Checker is a CLI software developed in Python 3.4, allowing users to verify the integrity of archives (tar,gz,bz2,lzma,zip,tree of files) and the state of the files inside an archive in order to find corruptions or intentional of accidental changes of states or removal of files inside an archive. Brebis version 0.9 was downloaded 1092 times. In order to keep the project growing, several steps were adopted recently: This new version 1.0 does not only provide project changes. Starting from 1.0, Backup Checker now verifies the owner name and the owner group name of a file inside an archive, enforcing the possible checks for both an archive and a tree of files. Moreover, the recent version 0.10 of Brebis published 9 days ago provided the following features As usual, any feedback is welcome, through bug reports, emails of the author or comments on this blog.

Laura Arjona: How contributors.debian.org helped in my email address migration

Some months ago I changed my preferred email address. I updated my profile in different sites to point to the new address, and changed my subscriptions in mailing lists. I forgot about subscriptions to Debian bugs. I like that you don t need a user to participate in Debian BTS (you just need an email address) but I learned that there s no way to get a list of the bugs you re subscribed to (for mailing lists it s possible: send mail to majordomo at lists.debian.org with which your.email.address in the body). Then, I remembered that I m listed in contributors.debian.org as BTS contributor, and that there is an extra info link, so I went there and got redirected to: https://bugs.debian.org/cgi-bin/pkgreport.cgi?correspondent=MYOLDADDRESS which lists all the bugs for which I sent an email (not only the bugs that I submitted). So now, I have a list of bug numbers to send -unsubscribe mails from my old address and then -subscribe mails from the new address. I m probably subscribed to some more bugs in which I didn t participate (just lurking or interested in how people deal with them) but I suppose they are not many. (I could have retrieved the list of bugs from the BTS interface, but contributors.debian.org came first to my mind, and it s nice to have that link handy there, isn t it?)

Antoine Beaupr : Migrating from Drupal to Ikiwiki

TLPL; j'ai chang de logiciel pour la gestion de mon blog. TLDR; I have changed my blog from Drupal to Ikiwiki. Note: since this post uses ikiwiki syntax (i just copied it over here), you may want to read the original version instead of this one. will continue operating for a while to
give a chance to feed aggregators to catch that article. It will also
give time to the Internet archive to catchup with the static
stylesheets (it turns out it doesn't like Drupal's CSS compression at
all!) An archive will therefore continue being available on the
internet archive for people that miss the old stylesheet. Eventually, I will simply redirect the anarcat.koumbit.org URL to
the new blog location, . This will likely be my
last blog post written on Drupal, and all new content will be
available on the new URL. RSS feed URLs should not change.

Why I am migrating away from Drupal because it is basically impossible to
upgrade my blog from Drupal 6 to Drupal 7. Or if it is, I'll have to
redo the whole freaking thing again when Drupal 8 comes along. And frankly, I don't really need Drupal to run a blog. A blog was
originally a really simple thing: a web blog. A set of articles
written on the corner of a table. Now with Drupal, I can add
ecommerce, a photo gallery and whatnot to my blog, but why would I do
that? and why does it need to be a dynamic CMS at all, if I get so
little comments? So I'm switching to ikiwiki, for the following reason:
  • no upgrades necessary: well, not exactly true, i still need to
    upgrade ikiwiki, but that's covered by the Debian package
    maintenance and I only have one patch to it, and there's no data migration! (the last such migration in ikiwiki was in 2009 and was fully supported)
  • offline editing: this is a a big thing for me: i can just note
    things down and push them when I get back online
  • one place for everything: this blog is where I keep my notes, it's
    getting annoying to have to keep track of two places for that stuff
  • future-proof: extracting content from ikiwiki is amazingly
    simple. every page is a single markdown-formatted file. that's it.
Migrating will mean abandoning the
barlow theme, which was
seeing a declining usage anyways.

What So what should be exported exactly. There's a bunch of crap in the old
blog that i don't want: users, caches, logs, "modules", and the list
goes on. Maybe it's better to create a list of what I need to extract:
  • nodes
    • title ([[ikiwiki/directive/meta]] title and guid tags, guid to avoid flooding aggregators)
    • body (need to check for "break comments")
    • nid (for future reference?)
    • tags (should be added as \[[!tag foo bar baz]] at the bottom)
    • URL (to keep old addresses)
    • published date ([[ikiwiki/directive/meta]] date directive)
    • modification date ([[ikiwiki/directive/meta]] updated directive)
    • revisions?
    • attached files
  • menus
    • RSS feed
    • contact
    • search
  • comments
    • author name
    • date
    • title
    • content
  • attached files
    • thumbnails
    • links
  • tags
    • each tag should have its own RSS feed and latest posts displayed

When Some time before summer 2015.

Who Well me, who else. You probably really don't care about that, so let'S
get to the meat of it.

How How to perform this migration... There are multiple paths:
  • MySQL commandline: extracting data using the commandline mysql tool (drush sqlq ...)
  • Views export: extracting "standard format" dumps from Drupal and
    parse it (JSON, XML, CSV?)
Both approaches had issues, and I found a third way: talk directly to
mysql and generate the files directly, in a Python script. But first,
here are the two previous approaches I know of.

MySQL commandline LeLutin switched using MySQL requests,
although he doesn't specify how content itself was migrated. Comments
importing is done with that script:
echo "select n.title, concat('  [[!comment  format=mdwn  username=\"', c.name, '\"  ip=\"', c.hostname, '\"  subject=\"', c.subject, '\"  date=\"', FROM_UNIXTIME(c.created), '\"  content=\"\"\" ', b.comment_body_value, ' \"\"\"]]') from node n, comment c, field_data_comment_body b where n.nid=c.nid and c.cid=b.entity_id;"   drush sqlc   tail -n +2   while read line; do if [ -z "$i" ]; then i=0; fi; title=$(echo "$line"   sed -e 's/[    ]\+ .*//' -e 's/ /_/g' -e 's/[:(),?/+]//g'); body=$(echo "$line"   sed 's/[^ ]*  //'); mkdir -p ~/comments/$title; echo -e "$body" &gt; ~/comments/$title/comment_$i._comment; i=$((i+1)); done
Kind of ugly, but beats what i had before (which was "nothing"). I do think it is the good direction to take, to simply talk to the
MySQL database, maybe with a native Python script. I know the Drupal
database schema pretty well (still! this is D6 after all) and it's
simple enough that this should just work.

Views export [[!img 2015-02-03-233846_1440x900_scrot.png class="align-right" size="300x" align="center" alt="screenshot of views 2.x"]] mvc recommended views data export on Lelutin's
blog. Unfortunately, my experience with the views export interface has
been somewhat mediocre so far. Yet another reason why I don't like
using Drupal anymore is this kind of obtuse dialogs: I clicked through those for about an hour to get JSON output that
turned out to be provided by views bonus instead of
views_data_export. And confusingly enough, the path and
format_name fields are null in the JSON output
(whyyy!?). views_data_export unfortunately only supports XML,
which seems hardly better than SQL for structured data, especially
considering I am going to write a script for the conversion anyways. Basically, it doesn't seem like any amount of views mangling will
provide me with what i need. Nevertheless, here's the [[failed-export-view.txt]] that I was able to
come up with, may it be useful for future freedom fighters.

Python script I ended up making a fairly simple Python script to talk directly to
the MySQL database. The script exports only nodes and comments, and nothing else. It makes
a bunch of assumptions about the structure of the site, and is
probably only going to work if your site is a simple blog like mine,
but could probably be improved significantly to encompass larger and
more complex datasets. History is not preserved so no interaction is
performed with git.

Generating dump First, I imported the MySQL dump file on my local mysql server for easier
development. It is 13.9MiO!!
mysql -e 'CREATE DATABASE anarcatblogbak;'
ssh aegir.koumbit.net "cd anarcat.koumbit.org ; drush sql-dump"   pv   mysql anarcatblogbak
I decided to not import revisions. The majority (70%) of the content has
1 or 2 revisions, and those with two revisions are likely just when
the node was actually published, with minor changes. ~80% have 3
revisions or less, 90% have 5 or less, 95% 8 or less, and 98% 10 or
less. Only 5 articles have more than 10 revisions, with two having the
maximum of 15 revisions. Those stats were generated with:
SELECT title,count(vid) FROM anarcatblogbak.node_revisions group
by nid;
Then throwing the output in a CSV spreadsheet (thanks to
mysql-workbench for the easy export), adding a column numbering the
rows (B1=1,B2=B1+1), another for generating percentages
(C1=B1/count(B$2:B$218)) and generating a simple graph with
that. There were probably ways of doing that more cleanly with R,
and I broke my promise to never use a spreadsheet again, but then
again it was Gnumeric and it's just to get a rough idea. There are 196 articles to import, with 251 comments, which means an
average of 1.15 comment per article (not much!). Unpublished articles
(5!) are completely ignored. Summaries are also not imported as such (break comments are
ignored) because ikiwiki doesn't support post summaries.

Calling the conversion script The script is in [[drupal2ikiwiki.py]]. It is called with:
./drupal2ikiwiki.py -u anarcatblogbak -d anarcatblogbak blog -vv
The -n and -l1 have been used for first tests as well. Use this
command to generate HTML from the result without having to commit and
push all:
ikiwiki --plugin meta --plugin tag --plugin comments --plugin inline  . ../anarc.at.html
More plugins are of course enabled in the blog, see the setup file for
more information, or just enable plugin as you want to unbreak
things. Use the --rebuild flag on subsequent runs. The actual
invocation I use is more something like:
ikiwiki --rebuild --no-usedirs --plugin inline --plugin calendar --plugin postsparkline --plugin meta --plugin tag --plugin comments --plugin sidebar  . ../anarc.at.html
I had problems with dates, but it turns out that I wasn't setting
dates in redirects... Instead of doing that, I started adding a
"redirection" tag that gets ignored by the main page.

Files and old URLs The script should keep the same URLs, as long as pathauto is enabled
on the site. Otherwise, some logic should be easy to add to point to
node/N. To redirect to the new blog, rewrite rules, on original blog, should
be as simple as:
Redirect / http://anarc.at/blog/
When we're sure:
Redirect permanent / http://anarc.at/blog/
Now, on the new blog, some magic needs to happen for files. Both
/files and /sites/anarcat.koumbit.org/files need to resolve
properly. We can't use symlinks because
ikiwiki drops symlinks on generation. So I'll just drop the files in /blog/files directly, the actual
migration is:
cp $DRUPAL/sites/anarcat.koumbit.org/files $IKIWIKI/blog/files
rm -r .htaccess css/ js/ tmp/ languages/
rm foo/bar # wtf was that.
rmdir *
sed -i 's#/sites/anarcat.koumbit.org/files/#/blog/files/#g' blog/*.mdwn
sed -i 's#http://anarcat.koumbit.org/blog/files/#/blog/files/#g' blog/*.mdwn
chmod -R -x blog/files
sudo chmod -R +X blog/files
A few pages to test images:
  • http://anarcat.koumbit.org/node/157
  • http://anarcat.koumbit.org/node/203
There are some pretty big files in there, 10-30MB MP3s - but those are
already in this wiki! so do not import them! Running fdupes on the result helps find oddities. The meta guid directive is used to keep the aggregators from finding
duplicate feed entries. I tested it with Liferea, but it may freak out
some other sites.

Remaining issues
  • postsparkline and calendar archive disrespect meta(date)
  • merge the files in /communication with the ones in /blog/files
    before import
  • import non-published nodes
  • check nodes with a format different than markdown (only a few 3=Full
    HTML
    found so far)
  • replace links to this wiki in blog posts with internal links

Daniel Pocock: Lumicall's 3rd Birthday

Today, 6 February, is the third birthday of the Lumicall app for secure SIP on Android. Happy birthday Lumicall's 1.0 tag was created in the Git repository on this day in 2012. It was released to the Google Play store, known as the Android Market back then, while I was in Brussels, the day after FOSDEM. Since then, Lumicall has also become available through the F-Droid free software marketplace for Android and this is the recommended way to download it. An international effort Most of the work on Lumicall itself has taken place in Switzerland. Many of the building blocks come from Switzerland's neighbours:
  • The ice4j ICE/STUN/TURN implementation comes from the amazing Jitsi softphone, which is developed in France.
  • The ZORG open source ZRTP stack comes from PrivateWave in Italy
  • Lumicall itself is based on the Sipdroid project that has a German influence, while Sipdroid is based on MjSIP which comes out of Italy.
  • The ENUM dialing logic uses code from ENUMdroid, published by Nominet in the UK. The UK is not exactly a neighbour of Switzerland but there is a tremendous connection between the two countries.
  • Google's libPhoneNumber has been developed by the Google team in Zurich and helps Lumicall format phone numbers for dialing through international VoIP gateways and ENUM.
Lumicall also uses the reSIProcate project for server-side infrastructure. The repro SIP proxy and TURN server run on secure and reliable Debian servers in a leading Swiss data center. An interesting three years for free communications Free communications is not just about avoiding excessive charges for phone calls. Free communications is about freedom. In the three years Lumicall has been promoting freedom, the issue of communications privacy has grabbed more headlines than I could have ever imagined. On 5 June 2013 I published a blog about the Gold Standard in Free Communications Technology. Just hours later a leading British newspaper, The Guardian, published damning revelations about the US Government spying on its own citizens. Within a week, Edward Snowden was a household name. Google's Eric Schmidt had previously told us that "If you have something that you don't want anyone to know, maybe you shouldn't be doing it in the first place.". This statement is easily debunked: as CEO of a corporation listed on a public stock exchange, Schmidt and his senior executives are under an obligation to protect commercially sensitive information that could be used for crimes such as insider trading. There is no guarantee that Lumicall will keep the most determined NSA agent out of your phone but nonetheless using a free and open source application for communications does help to avoid the defacto leakage of your conversations to a plethora of marketing and profiling companies that occurs when using a regular phone service or messaging app. How you can help free communications technology evolve As I mentioned in my previous blog on Lumicall, the best way you can help Lumicall is by helping the F-Droid team. F-Droid provides a wonderful platform for distributing free software for Android and my own life really wouldn't be the same without it. It is a privilege for Lumicall to be featured in the F-Droid eco-system. That said, if you try Lumicall and it doesn't work for you, please feel free to send details from the Android logs through the Lumicall issue tracker on Github and they will be looked at. It is impossible for Lumicall developers to test every possible phone but where errors are obvious in the logs some attempt can be made to fix them. Beyond regular SIP Another thing that has emerged in the three years since Lumicall was launched is WebRTC, browser based real-time communications and VoIP. In its present form, WebRTC provides tremendous opportunities on the desktop but it does not displace the need for dedicated VoIP apps on mobile handsets. WebRTC applications using JavaScript are a demanding solution that don't integrate as seamlessly with the Android UI as a native app and they currently tend to be more intensive users of the battery. Lumicall users can receive calls from desktop users with a WebRTC browser using the free calling from browser to mobile feature on the Lumicall web site. This service is powered by JSCommunicator and DruCall for Drupal.

Carl Chenet: Backup Checker 1.0, the fully automated backup checker

Follow me on Identi.ca or Twitter or Diaspora*diaspora-banner Backup Checker is the new name of the Brebis project. Backup Checker is a CLI software developed in Python 3.4, allowing users to verify the integrity of archives (tar,gz,bz2,lzma,zip,tree of files) and the state of the files inside an archive in order to find corruptions or intentional of accidental changes of states or removal of files inside an archive. Brebis version 0.9 was downloaded 1092 times. In order to keep the project growing, several steps were adopted recently: This new version 1.0 does not only provide project changes. Starting from 1.0, Backup Checker now verifies the owner name and the owner group name of a file inside an archive, enforcing the possible checks for both an archive and a tree of files. Moreover, the recent version 0.10 of Brebis published 9 days ago provided the following features As usual, any feedback is welcome, through bug reports, emails of the author or comments on this blog.

Daniel Pocock: Debian Maintainer Dashboard now provides iCalendar feeds

Contributors to Debian can now monitor their list of pending activities using iCalendar clients on their desktop or mobile device. Thanks to the tremendous work of the Debian QA team, the Ultimate Debian Database has been scooping up data from all around the Debian universe and storing it in a PostgreSQL back-end. The Debian Maintainer Dashboard allows developers to see a summary of outstanding issues across all their packages in a range of different formats. With today's update, an aggregated list of Debian tasks and to-dos can now be rendered in iCalendar format and loaded into a range of productivity tools. Using the iCalendar URL Many productivity tools like Mozilla Lightning (Iceowl extension on Debian) allow you to poll any calendar or task list just using a URL. For UDD iCalendar feeds, the URLs look like this:
https://udd.debian.org/dmd/?format=ics&email1=daniel%40pocock.pro
You can also get the data by visiting the Debian Maintainer Dashboard, filling out the form and selecting the iCalendar output format. Next steps Currently, the priority and deadline attributes are not set on any of the tasks in the feed. The strategy of prioritizing issues has been raised in bug #777112. iCalendar also supports other possibilities such as categories and reminders/alarms. It is likely that each developer has their own personal preferences about using these features. Giving feedback through the Debian QA mailing list or the bug tracker is welcome. Screenshots

Charles Plessy: News of the package mime-support.

The package mime-support is installed by default on Debian systems. It has two roles: first to provide the file /etc/mime.types that associates media types (formerly called MIME types) to suffixes of file names, and second to provide the mailcap system that associates media types with programs. I adopted this package at the end of the development cycle of Wheezy. Changes since Wheezy. The version distributed in Jessie brings a few additions in /etc/mime.types. Among them, application/vnd.debian.binary-package and text/vnd.debian.copyright, which as their name suggest describe two file formats designed by Debian. I registered these types to the IANA, which is more open to the addition of new types since the RFC 6838. The biggest change is the automatic extraction of the associations between programs and media types that are declared in the menu files in FreeDesktop format. Before, it was the maintainer of the Debian package who had to extract this information and translate it in mailcap format by hand. The automation is done via dpkg triggers. A big thank you to Kevin Ryde who gave me a precious help for the developments and corrections to the run-mailcap program, and to all the other contributors. Your help is always welcome! Security updates. In December, Debian has been contacted by Timothy D. Morgan, who found that an attacker could get run-mailcap to execute commands by inserting them in file names (CVE-2014-7209). This first security update for me went well, thanks to the help and instructions of Salvatore Bonaccorso from the Security team. The problem is solved in Wheezy, Jessie and Sid, as well as in Squeeze through its long term support. One of the consequences of this security update is that run-mailcap will systematically use the absolute path to the files to open. For harmless files, this is a bit ugly. This will perhaps be improved after Jessie is released. Future projects The file /etc/mime.types is kept up to date by hand; this is slow and inefficient. The package shared-mime-info contains similar information, that could be used to autogenerate this file, but that would require to parse a XML source that is quite complex. For the moment, I am considering to import Fedora's mailcap package, where the file /etc/mime.types is very well kept up to date. I have not yet decided how to do it, but maybe just by moving that file from one package to the other. In that case, we would have the mime-support package that would provide mailcap support, and the package whose source is Fedora's mailcap package who would provide /etc/mime.types. Perhaps it will be better to use clearer names, such as mailcap-support for the first and media-types for the second? Separating the two main functionalities of mime-support would have an interesting consequence: the possibility of not installing the support for the mailcap system, or to make it optional, and instead to use the FreeDesktop sytem (xdg-open), from the package xdg-utils. Something to keep in mind...

Started testing Kilo beta 1. Fixed a few issues on default configuration for Ceilometer and Glance. Monday 05:
Fixed openstack-pkg-tools which failed to create PID files at boot time, Uploaded to Sid, asked the release team for unblock.
Uploaded ceilometer & cinder to Sid, rebuilt against openstack-pkg-tools 21.
Did more testing of Kilo beta 1, fixed a few more minor issues. Tuesday 06:
Uploaded glance, neutron, nova, designate, keystone, heat, trove to Sid, so that all sysv-rc init scripts are fixed with the new openstack-pkg-tools 21. Designate, heat, keystone and trove contains other minor fixes reported to the Debian BTS. Wednesday 07:
Asked the Debian release team (open bugs with debdiff as attachment) for unblocks of glance, neutron, nova, designate, keystone, heat, trove so they migrate to Jessie.
Fixed a few minor issues tracked in the Debian BTS on various packages. Thesday 08:
James Page from Canonical informed me that they are now using openstack-pkg-tools for maintaining their daemons in Nova, Cinder and Keystone in Ubuntu. That s an awesome news : more QA for both platforms.
James Page found out that dh_installinit *must* be called *after* the call of dh_systemd_enable, otherwise, daemons aren t started automatically at the first install of packages, as the unmask of systemd happens after the invoke-rc.d. Friday 09:
Did some QA checks on the latest upload. Fixed Heat which broke because using the wrong template name (glance instead of heat). Monday 12:
Started re-running the automated openstack-deploy scrip in Icehouse, Juno and Kilo. Found out the issue in Keystone wasn t fixed in Juno (but was fixed in other releases), and fixed it.
Removed the use of ssl.PROTOCOL_SSLv3 from heat (removed form Debian). Uploaded the fixed package to Sid.
All of openstack-deploy (debian/kilo branch) now works and succesfully installs OpenStack again. If dh_installinit is called before, we have:
# Automatically added by dh_installinit
if [ -x "/etc/init.d/keystone" ]; then
update-rc.d keystone defaults >/dev/null
fi
if [ -x "/etc/init.d/keystone" ]   [ -e "/etc/init/keystone.conf" ]; then
invoke-rc.d keystone start   true
fi
# End automatically added section
# Automatically added by dh_systemd_enable
# This will only remove masks created by d-s-h on package removal.
deb-systemd-helper unmask keystone.service >/dev/null   true
# was-enabled defaults to true, so new installations run enable.
if deb-systemd-helper --quiet was-enabled keystone.service; then
# Enables the unit on first installation, creates new
# symlinks on upgrades if the unit file has changed.
deb-systemd-helper enable keystone.service >/dev/null   true
else
# Update the statefile to add new symlinks (if any), which need to be
# cleaned up on purge. Also remove old symlinks.
deb-systemd-helper update-state keystone.service >/dev/null   true
fi
# End automatically added section
If it s called after dh_systemd_enable, we have:
# Automatically added by dh_systemd_enable
# This will only remove masks created by d-s-h on package removal.
deb-systemd-helper unmask keystone.service >/dev/null   true
# was-enabled defaults to true, so new installations run enable.
if deb-systemd-helper --quiet was-enabled keystone.service; then
# Enables the unit on first installation, creates new
# symlinks on upgrades if the unit file has changed.
deb-systemd-helper enable keystone.service >/dev/null   true
else
# Update the statefile to add new symlinks (if any), which need to be
# cleaned up on purge. Also remove old symlinks.
deb-systemd-helper update-state keystone.service >/dev/null   true
fi
# End automatically added section
# Automatically added by dh_installinit
if [ -x "/etc/init.d/keystone" ]; then
update-rc.d keystone defaults >/dev/null
fi
if [ -x "/etc/init.d/keystone" ]   [ -e "/etc/init/keystone.conf" ]; then
invoke-rc.d keystone start   true
fi
# End automatically added section
As a consequence, I have to re-upload version 22 of openstack-pkg-tools and also re-upload all OpenStack core packages to Debian Sid. Fixed a number of issues like:
* dbc_upgrade = true check which shouldn t have been there in postinst.
* <project>/configure_db default value is now always false
* db_sync and pkgos_dbc_postinst are now only done if <project>/configure_db is set to true.
Rebuilt all packages in Juno and Kilo with the above changes. Tuesday 13:
Opened unblock bugs for the release team to unblock all fixed packages.
Made more tests in Juno and Kilo to make sure the fixed bugs in Icehouse are fixed there too.
Fixed numerous issues in Trove (missing trove-conductor.conf, wrong trove-api init file, etc.). More work will be needed for it for both Icehouse and newer releases. Wednesday 14:
Did a doc meeting about debconf. Some doc contributors still want to kill the debconf / debian manual, and I have to not agree.
Made a new patch to better document the keystone install procedure:
Did some bug triaging in the doc about Debian.
Uploaded new versions of core packages to Experimental (eg: Juno) built against openstack-pkg-tools >= 22~, and some fixes forward ported from Icehouse: Keystone, Ceilometer, Cinder, Glance, Heat, Ironic, Murano, Neutron, Nova, Saraha and Murano-agent. All where rebuilt in Juno (Wheezy + Trusty) and Kilo (Jessie only) on my Jenkins. Thuesday 15:
Succesfully booted a live-build Debian live image containing mcollective and nailgun-agent as a Debian replacement for the hardware discovery / boostrap image of Fuel. Now, I need to find a way to use just a kernel + initramfs Friday 16 to Tuesday 20:
Worked on the packaging CI. Wednesday 21:
Fixed https://bugs.debian.org/775636 (Horizon failed to build due to a Moscow timezone change and wrong test). Uploaded to Sid, asked for unblock.
Fixed https://bugs.debian.org/775926: CVE-2015-1195: Glance still allows users to download and delete any file in glance-api server (applied upstream patch). Uploaded to Sid, asked for unblock. Uploaded Juno version to Experimental.
Uploaded openstack-trove with the remaining fixes, asked release team for unblock.
Uploaded python-glanceclient 0.15.0 (Juno) to Experimental because it fixes an issue with HTTPS. Added to it a patch from James Page not yet merged, which fixes unit test with Python 2.7.9 (7 failures otherwise).
Uploaded python-xstatic-d3 as it can t be installed anymore in Sid after a new version of d3 was uploaded. Thursday 22:
Uploaded python-xstatic-smart-table and libjs-angularjs-smart-table to Sid (new packages, now in NEW queue). Friday 23:
Ask for the removal of the below list of packages from Jessie:
python-xstatic
python-xstatic-angular
python-xstatic-angular-cookies
python-xstatic-angular-mock
python-xstatic-bootstrap-datepicker
python-xstatic-bootstrap-scss
python-xstatic-d3
python-xstatic-font-awesome
python-xstatic-hogan
python-xstatic-jasmine
python-xstatic-jquery
python-xstatic-jquery-migrate
python-xstatic-jquery-ui
python-xstatic-jquery.bootstrap.wizard
python-xstatic-jquery.quicksearch
python-xstatic-jquery.tablesorter
python-xstatic-jsencrypt
python-xstatic-qunit
python-xstatic-rickshaw
python-xstatic-spin
libjs-jsencrypt
libjs-spin.js
libjs-twitter-bootstrap-datepicker
libjs-twitter-bootstrap-wizard They are used only in OpenStack Horizon starting on 2014.2 (aka Juno), and Jessie is shipped with Icehouse, so it s IMO best to not carry the burden of maintaining these packages for the life of Jessie. Monday 26:
Enhanced and review requested changes for https://review.openstack.org/147296 (ie: Keystone install with more details about what the package does).
Finished testing network on the CI install. Now need to automate all. Tuesday 27:
Closed all bugs on the rabbitmq-server package (2 correction, one bug triage).
Uploaded a fix for the missing conntrack dependency in neutron-l3-agent.
Restarted working on CI setup of Juno after success with manual install in a Xen domU.
Uploaded fix to make sheepdog build reproducible (patch from the Debian BTS). Thursday 28:
Fixed and uploaded to Sid openstack-debian-images 2 bugs reported by Steve McIntire. Official Debian images for OpenStack are now available at:
http://cdimage.debian.org/cdimage/openstack/ \o/
Note that this is the weekly build of testing. We wont get Debian Stable images before Jessie is out.
Documented the new image thing here: http://docs.openstack.org/image-guide/content/ch_obtaining_images.html#debian-images as a new patch: https://review.openstack.org/#/c/151015/
Fixed my patch for keystone debconf doc at: https://review.openstack.org/#/c/147296/ Wednesday 29:
Continued working on packaging CI Thursday 30:
Fixed CVE on Neutron (Juno): L3 agent denial of service with radvd 2.0+
Fixed CVE on Glance (Icehouse + Juno): Glance user storage quota bypass. Asked release team for unblock.
Fixed the image-guide patch after review (ie: https://review.openstack.org/151015)

Ritesh Raj Sarraf: Debian GNU/Hurd on VirtualBox

One of the great things about Debian is the wide range of kernels it supports can run. This gives the user the flexibility to not spend time on the common userland stuff. For example, most apps, package management and system admin tasks are common across all Debian platforms. These platforms may not be optimal at par to Linux, but still, choice is good. For long, I had used Debian GNU/Hurd, only on a KVM hypervisor. Recently being involved in VirtualBox maintenance, I've almost beeing using VirtualBox for all my virtualization tasks. So it was time to try out Hurd on VirtualBox. All praises to the work the Debian Hurd team has put, it just works wonderfully. To try out Hurd on VirtualBox:
  1. You could download ready to use VirtualBox images from here.
  2. These are raw images. For VirtualBox, I'd recommend you convert the image to VDI format.
    1. rrs@learner:~/VirtualBox VMs$ VBoxManage convertdd debian-hurd-20150105.img debian-hurd-20150105.vdi --format VDI
      Converting from raw image file="debian-hurd-20150105.img" to file="debian-hurd-20150105.vdi"...
      Creating dynamic image with size 3146776576 bytes (3001MB)...
    2. The VDI format may help in with some of the goodies VirtualBox has to offer, like efficient snapshots.
  3. The rest remains the same. You need to configure the VM just as else. Currently supported arch is x86 only, so make the selections accordingly.
  4. The final VM config may look something like the following screenshot.
  5. And here's the result in a video captured on VirtualBox running Debian GNU/Hurd.

Manuel A. Fernandez Montecelo: Hallo, Planet Debian!

Hi! I just created this blog and asked to get it aggregated to the Debian Planet, so first things first -- in the initial post I wanted to say Hallooooo! to the people in the community and to talk about my work and interests in Debian. Probably most of you never interacted with or even heard of me before. I am contributor/Maintainer since ~2010 and Developer only for ~2 years, and most of the things that I worked in or packages that I maintain are "low profile" or unintrusive, except perhaps for work in aptitude and SDL libraries, if you happen to be interested in these packages or others that I [co-]maintain. More recently, during 2014, I was helping to bootstrap and bring to life a new architecture, OpenRISC or1k. Perhaps I should devote a future post to explain a bit more about the history, status and news --or, lately, lack thereof-- about this port. This is one of the main reasons why I thought that it would be useful to have a blog -- to register activities for which it is difficult to get information by other means. Apart from or1k, as it often happens with porting efforts in Debian, the work done also helped indirectly other architectures added last year (mips64el, arm64, ppc64el). Additionally, a few of my NMUs were directly targetted to help ppc64el to get ready in time for the architecture evaluation. None of the porters working in ppc64el were Debian Maintainers/Developers and some of the patches that they created did not benefit directly the other ports, so in the packages without active maintainers, the requests were not getting much attention in the crucial time before the evaluation. In some cases, these packages were in the critical path to build many other packages or support important user-case scenarios. So I was very pleased when I learnt that arm64 and ppc64el will be in the next stable release --Jessie-- as officially supported architectures. They came without much noise or ceremonious celebrations, but I think that this is a great success story for these architectures and for Debian, and even for the computing world in general. Time will tell. In the meantime, congratulations to all people involved! In addition to porting packages within Debian, I also sent some patches upstream to get the packages that I maintain compiling in the new architectures, and sent upstream patches needed to support or1k specifically (jemalloc, nspr, libgc, cmake, components of X.org...). Enough for the first post. Just to finish, let me say that after about a decade without a personal website or blog (the previous ones not about Debian or even computing), here I am again. Let's see how it goes and I hope to have enough interesting things to tell you to keep the blog alive. Or, in other words... To infinity and beyond!

Rapha&#235;l Hertzog: My Free Software Activities for January 2015

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donators (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it s one of the best ways to find volunteers to work with me on projects that matter to me. Debian LTS This month I have been paid to work 12 hours on Debian LTS. I did the following tasks: I want to expand on two cases that I stumbled upon in my CVE triage work and that took quite long to investigate each. While my after-the-fact description is rather straightforward, the real process involved more iterations and data gathering that I do not mention here. First I was investigating CVE-2012-6685 on libnokogiri-ruby and the upstream bug discussion revealed that libxml2 could also be part of the problem. Using the tests cases submitted there, I confirmed that libxml2 was also affected by an issue of its own then I started to analyze the history of CVE of libxml2 to find out whether that issue got a CVE assigned: yes, that was CVE-2014-0191 (although the CVE description is unrelated). But this CVE was marked as fixed in all releases. Why? It turns out that the upstream fix for this CVE is just the complement of another commit that was merged way earlier (and that was used as a basis for the commit as the copy/paste of the comment shows). When the security teams integrated the upstream patch in wheezy/squeeze, they were probably not aware that a full fix required to also include something else. In the end, I thus reopened CVE-2014-0191 on our tracker (commit here). The second problematic case was pound. Thijs Kinkhorst added pound related data on the multiple (high profile) SSL related issues. So it appeared on my radar of new vulnerable package in Squeeze because it was marked that CVE-2009-3555 was fixed in version 2.6-2 while Squeeze has 2.5-1. There was no bug reference in the security tracker and the Debian changelog for that version only mentioned an anti_beast patch which is yet another issue (CVE-2011-3389). I had to dig a bit deeper in the end I discovered that the above patch also has provisions for the CVE that was of interest to me, except that Brian May recently reported in #765649 that the package was still vulnerable to this issue I tried to understand where the above patch was failing and thus submitted my findings to the bug. And I updated the tracker data with my newly gained knowledge (commit 31751 and 31752). Tryton For me, January is always the month where I try to close the accounting books of Freexian. This year is no exception except that it s the first year where I do this with Tryton. I first upgraded to Tryton 3.4 to have the latest version. Despite this I discovered multiple problems while doing so since I don t want to have those problems next year, I reported them and prepared fixes for those related to the French chart of accounts: Saltstack I mentioned this idea last month setting up and maintaining a lot of sbuild chroots can be tiresome so I wanted to automate this as much as possible. To achieve this I created three Salt formulas and got them added to the official Saltstack repository: Each one builds on top of the former. debootstrap-formula creates chroots with debootstrap or cdebootstrap. schroot-formula does the same and registers those chroots in schroot. And sbuild-formula does the same as schroot-formula but with different defaults that are more suited to sbuild chroots (and obviously ensures that sbuild is installed and that generated chroots are buildd chroots). With the sbuild formula I can put this in pillar data:
sbuild:
  chroots:
    wheezy:
      architectures: [amd64, i386]
      extra_dists:
        - wheezy-backports
        - wheezy-security
      extra_aliases:
        - wheezy-backports
        - stable-security
        - wheezy-security
    jessie:
    [...]
And then a simple salt-call state.highstate (I m running in standalone mode) will ensure that I have all the chroots properly setup. Misc packaging I packaged new upstream releases of Django in experimental and opened a pre-approval request to get the latest 1.7.x in jessie (#775892). It seems to be a difficult sell for the release team, which is a pity because we have active Debian developers, active upstream developers, and everybody is well aware of the no-new features rule to avoid regressions. Where is the risk? I also filed an unblock request for Dolibarr (on the request of the security team which wants to see the CVE fix reach Jessie). I did small contributions to two bugs that were of special interest to some of my donators (#751339 and #774811), they were not under my responsibility but I tried to get them moving by pinging the relevant people. I prepared a security upload for Django in Wheezy (python-django_1.4.5-1+deb7u9) and sent it to the security team. While doing this I discovered a small problem in their backported patch that I reported upstream in Django s ticket #24239. Debian France With the new year, it s again time to organize a general assembly with the election of a third of its board. So we solicited candidacies among the members and I m pleased to see that we got 6 candidacies for the 3 seats. It s a good sign that we still have enough persons caring about the association. One of them is even speaking of Debconf 17 in France great plans! On my side, I announced that I would not candidate to be president for the next year. I will stay on the board though to ensure we have a smooth transition. Thanks See you next month for a new summary of my activities.
