Raphaël Hertzog: My Free Software Activities in January 2018

Planet Ubuntu - Enj, 01/02/2018 - 4:08md

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donors (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

While I continue to manage the administrative side of Debian LTS, I’m taking a break of the technical work (i.e. preparing and releasing security updates). The hope is that it will help me focus more on my book which (still) needs to be updated for stretch. In truth, this did not happen in January but I hope to do better in the upcoming months.

Salsa and related

The switch to salsa.debian.org is a major event in our community. Last month I started with the QA team and the distro-tracker repository as an experiment. This month I took this opportunity to bring to fruition a merge between the pkg-security team and the forensics team that I already proposed in the past and that we postponed because it was deemed busy work for no gains. Now that both teams had to migrate anyway, it was easier to migrate everything at once under a single project.

All our repositories are now managed under the same team in salsa: https://salsa.debian.org/pkg-security-team/ But for the mailing list we are still waiting for the new list to be created on lists.debian.org (#888136).

As part of this work, I contributed some fixes to the scripts maintained by Mehdi Dogguy. I also filed a wishlist request for a new script to make it easy to share repositories with the Debian group.

With the expected demise of alioth mailing lists, there’s some interest in getting the Debian package tracker to host the official maintainer email. As the central hub for most emails related to packages, it seems natural indeed. We made some progress lately on making it possible to use @packages.debian.org emails (with the downside of receiving duplicate emails currently) but that’s not an really an option when you maintain many packages and want to see them grouped under the same maintainer email. Furthermore it doesn’t allow for automatic association of a package to its maintainer team. So I implemented a team+slug@tracker.debian.org email that works for each team registered on the package tracker and that will automatically associate the package to its team. The email is just a black hole for now (not really a problem as most automatic emails are already received through another email) but I expect to forward non-automatic mails to team members to make it useful as a way to discuss between team members.

The package tracker also learned to recognize commit mails generated by GitLab and it will now forward them to the source package whose name is matching the name of the GitLab project that generated them (see #886114).

Misc Debian stuff

Distro Tracker. I got my two first merge requests which I reviewed and merged. One adds native HTML support to toggle action items (i.e. without javascript on recent browsers) and the other improves some of the messages shown by the vcswatch integration. In #886450, we discussed how to better filter build failure mails sent by the build daemons. New headers have been added.

Bug reports and patches. I forwarded and/or got moving a couple of bugs that we encountered in Kali (glibc: new data brought to #820826, raspi3-firmware: #887062, glibc: tracking down #886506 to a glibc regression affecting busybox, gr-fcdproplus: #888853 new watch file, gjs: upstream bug #33). I also needed a new feature in live-build so I filed #888507 which I implemented almost immediately (but released only in Kali because it’s not documented yet and can possibly be improved a bit further).

While doing my yearly accounting, I opened an issue on tryton and pushed a fix after approval. While running unit tests on distro-tracker, I got an unexpected warning that seems to be caused by virtualenv (see upstream issue #1120).

Debian Packaging. I uploaded zim 0.68~rc1-1 to experimental.

Thanks

See you next month for a new summary of my activities.

Our future relationship with FSFE

Planet Debian - Enj, 01/02/2018 - 2:19md

Below is an email that has been distributed to the FSFE community today. FSFE aims to be an open organization and people are welcome to discuss it through the main discussion group (join, thread and reply) whether you are a member or not.

For more information about joining FSFE, local groups, campaigns and other activities please visit the FSFE web site. The "No Cloud" stickers and the Public Money Public Code campaign are examples of initiatives started by FSFE - you can request free stickers and posters by filling in this form.

Dear FSFE Community,

I'm writing to you today as one of your elected fellowship representatives rather than to convey my own views, which you may have already encountered in my blog or mailing list discussions.

The recent meeting of the General Assembly (GA) decided that the annual elections will be abolished but this change has not yet been ratified in the constitution.

Personally, I support an overhaul of FSFE's democratic processes and the bulk of the reasons for this change are quite valid. One of the reasons proposed for the change, the suggestion that the election was a popularity contest, is an argument I don't agree with: the same argument could be used to abolish elections anywhere.

One point that came up in discussions about the elections is that people don't need to wait for the elections to be considered for GA membership. Matthias Kirschner, our president, has emphasized this to me personally as well, he looks at each new request with an open mind and forwards it to all of the GA for discussion. According to our constitution, anybody can write to the president at any time and request to join the GA. In practice, the president and the existing GA members will probably need to have seen some of your activities in one of the FSFE teams or local groups before accepting you as a member. I want to encourage people to become familiar with the GA membership process and discuss it within their teams and local groups and think about whether you or anybody you know may be a good candidate.

According to the minutes of the last GA meeting, several new members were already accepted this way in the last year. It is particularly important for the organization to increase diversity in the GA at this time.

The response rate for the last fellowship election was lower than in previous years and there is also concern that emails don't reach everybody thanks to spam filters or the Google Promotions tab (if you use gmail). If you had problems receiving emails about the last election, please consider sharing that feedback on the discussion list.

Understanding where the organization will go beyond the extinction of the fellowship representative is critical. The Identity review process, championed by Jonas Oberg and Kristi Progri, is actively looking at these questions. Please contact Kristi if you wish to participate and look out for updates about this process in emails and Planet FSFE. Kristi will be at FOSDEM this weekend if you want to speak to her personally.

I'll be at FOSDEM this weekend and would welcome the opportunity to meet with you personally. I will be visiting many different parts of FOSDEM at different times, including the FSFE booth, the Debian booth, the real-time lounge (K-building) and the Real-Time Communications (RTC) dev-room on Sunday, where I'm giving a talk. Many other members of the FSFE community will also be present, if you don't know where to start, simply come to the FSFE booth. The next European event I visit after FOSDEM will potentially be OSCAL in Tirana, it is in May and I would highly recommend this event for anybody who doesn't regularly travel to events outside their own region.

Changing the world begins with the change we make ourselves. If you only do one thing for free software this year and you are not sure what it is going to be, then I would recommend this: visit an event that you never visited before, in a city or country you never visited before. It doesn't necessarily have to be a free software or IT event. In 2017 I attended OSCAL in Tirana and the Digital-Born Media Carnival in Kotor for the first time. You can ask FSFE to send you some free stickers and posters (online request with optional donation) to give to the new friends you meet on your travels. Change starts with each of us doing something new or different and I hope our paths may cross in one of these places.

For more information about joining FSFE, local groups, campaigns and other activities please visit the FSFE web site.

Please feel free to discuss this through the FSFE discussion group (join, thread and reply)

Free software activities in January 2018

Planet Debian - Mër, 31/01/2018 - 11:20md

Here is my monthly update covering what I have been doing in the free software world in January 2018 (previous month):

Reproducible builds

Whilst anyone can inspect the source code of free software for malicious flaws, most software is distributed pre-compiled to end users.

The motivation behind the Reproducible Builds effort is to allow verification that no flaws have been introduced — either maliciously or accidentally — during this compilation process by promising identical results are always generated from a given source, thus allowing multiple third-parties to come to a consensus on whether a build was compromised.

I have generously been awarded a grant from the Core Infrastructure Initiative to fund my work in this area.

This month I:



I also made the following changes to our tooling:

diffoscope

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

  • New features:
    • Compare JSON files using the jsondiff module. (#888112)
    • Report differences in extended file attributes when comparing files. (#888401)
    • Show extended filesystem metadata when directly comparing two files not just when we specify two directories. (#888402)
    • Do some fuzzy parsing to detect JSON files not named .json. [...]
  • Bug fixes:
    • Return unknown if we can't parse the readelf version number for (eg.) FreeBSD. (#886963)
    • If the LLVM disassembler does not work, try the internal one. (#886736)
  • Misc:
    • Explicitly depend on e2fsprogs. (#887180)
    • Clarify Unidentified file log message as we did try and lookup via the comparators first. [...]

I also fixed an issue in the "trydiffoscope" command-line client that was preventing installation on non-Debian systems (#888882).


disorderfs

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

  • Correct "explicitly" typo in disorderfs.1.txt. [...]
  • Bump Standards-Version to 4.1.3. [...]
  • Drop trailing whitespace in debian/control. [...]


Debian

My activities as the current Debian Project Leader are covered in my "Bits from the DPL" email to the debian-devel-announce mailing list.

In addition to this, I:

  • Published whydoesaptnotusehttps.com, an overview of why APT does not rely solely on SSL for validation of downloaded packages as I noticed it was being asked a lot on support forums.
  • Reported a number of issues for the mentors.debian.net review service.
Patches contributed
  • dput: Suggest --force if package has already been uploaded. (#886829)
  • linux: Add link to the Firmware page on the wiki to failed to load log messages. (#888405)
  • markdown: Make markdown exit with a non-zero exit code if cannot open input file. (#886032)
  • spectre-meltdown-checker: Return a sensible exit code. (#887077)
Debian LTS

This month I have been paid to work 18 hours on Debian Long Term Support (LTS). In that time I did the following:

  • Initial draft of a script to automatically detect when CVEs should be assigned to multiple source packages in the case of legacy renames, duplicates or embedded code copies.
  • Issued DLA 1228-1 for the poppler PDF library to fix an overflow vulnerability.
  • Issued DLA 1229-1 for imagemagick correcting two potential denial-of-service attacks.
  • Issued DLA 1233-1 for gifsicle — a command-line tool for manipulating GIF images — to fix a use-after-free vulnerability.
  • Issued DLA 1234-1 to fix multiple integer overflows in the GTK gdk-pixbuf graphics library.
  • Issued DLA 1247-1 for rsync, fixing a command-injection vulnerability.
  • Issued DLA 1248-1 for libgd2 to prevent a potential infinite loop caused by signedness confusion.
  • Issued DLA 1249-1 for smarty3 fixing an arbitrary code execution vulnerability.
  • "Frontdesk" duties, triaging CVEs, etc.
Uploads
  • adminer (4.5.0-1) — New upstream release.
  • bfs (1.2-1) — New upstream release.
  • dbus-cpp (5.0.0+18.04.20171031-1) — Initial upload to Debian.
  • installation-birthday (7) — Add e2fsprogfs to Depends so it can drop Essential: yes. (#887275
  • process-cpp:
    • 3.0.1-1 — Initial upload to Debian.
    • 3.0.1-2 — Fix FTBFS due to symbol versioning.

    • 5:4.0.6-3 — Use --clients argument to runtest to force single-threaded operation over using taskset.
    • 5:4.0.6-4 — Re-add procps to Build-Depends. (#887075)
    • 5:4.0.6-5 — Fix a dangling symlink (and thus a broken package). (#884321)
    • 5:4.0.7-1 — New upstream release.
  • redisearch (1.0.3-1, 1.0.4-1 & 1.0.5-1) — New upstream releases.
  • trydiffoscope (67.0.0) — New upstream release.

I also sponsored the following uploads:

Debian bugs filed

Day three of the pre-FOSDEM Debconf Videoteam sprint

Planet Debian - Mër, 31/01/2018 - 7:46md

This should really have been the "day two" post, but I forgot to do that yesterday, and now it's the end of day three already, so let's just do the two together for now.

Kyle

Has been hacking on the opsis so we can get audio through it, but so far without much success. In addition, he's been working a bit more on documentation, as well as splitting up some data that's currently in our ansible repository into a separate one so that other people can use our ansible configuration more easily, without having to fork too much.

Tzafrir

Did some tests on the ansible setup, and did some documentation work, and worked on a kodi plugin for parsing the metadata that we've generated.

Stefano

Did some work on the DebConf website. This wasn't meant to be much, but yak shaving sucks. Additionally, he's been doing some work on the youtube uploader as well.

Nattie

Did more work reviewing our documentation, and has been working on rewording some of the more awkward bits.

Wouter

Spent much time on improving the SReview installation for FOSDEM. While at it, fixed a number of bugs in some of the newer code that were exposed by full tests of the FOSDEM installation. Additionally, added code to SReview to generate metadata files that can be handed to Stefano's youtube uploader.

Pollo

Although he had less time yesterday than he did on monday (and apparently no time today) to sprint remotely, Pollo still managed to add a basic CI infrastructure to lint our ansible playbooks.

Swatantra17

Planet Debian - Mër, 31/01/2018 - 2:49md

Its very late but here it goes..

Last month Thiruvananthapuram witnessed one of the biggest Free and Open Source Software conference called Swatantra17. Swatantra is a flagship triennial ( actually used to be triennial, but from now on organizers decided to conduct in every 2 years.) FOSS conference from ICFOSS. This year there were more than 30 speakers from all around the world. The event held from 20-21 December at Mascot hotel, Thiruvananthapuram. I was one of the community volunteer for the event and was excited from the day it announced :) .

Current Kerala Chief Minister Pinarayi Vijayan inaugurated Swatantra17. The first day session started with keynote from Software Freedom Conservancy executive director Karen Sandler. Karen told about safety of medical devices like defibrillator which runs proprietary software. After that there were many parallel talks about various free software projects,technologies and tools. This edition of Swatantra focused more on art. It was good to know more about artist’s free software stack. Most amazing thing is through out the conference I met so many people from FSCI whom I only know through matrix/IRC/emails.

The first day talks were ended at 6PM. After that Oorali band performed for us. This band is well-known in Kerala because they speak for many social and political issues. This make them best match for a free software conference cultural program :). Their songs are mainly about birds, forests, freedom and we danced to the many of the songs.

Last day evening there was kind of BoF from FSF person Benjamin Mako Hill. Half way through I came to know he is also a Debian Developer :D. Unfortunately this Bof stopped as he was called for a panel discussion. After the panel discussion we all Debian people gathered and had a chat.

Migrating the debichem group subversion repository to Git - Part 1: svn-all-fast-export basics

Planet Debian - Mër, 31/01/2018 - 1:24md

With the deprecation of alioth.debian.org the subversion service hosted there will be shut down too. According to lintian the estimated date is May 1st 2018 and there are currently more then 1500 source packages affected. In the debichem group we've used the subversion service since 2006. Our repository contains around 7500 commits done by around 20 different alioth user accounts and the packaging history of around 70 to 80 packages, including packaging attempts. I've spent the last days to prepare the Git migration, comparing different tools, controlling the created repositories and testing possibilities to automate the process as much as possible. The resulting scripts can currently be found here.

Of course I began as described at the Debian Wiki. But following this guide, using git-svn and converting the tags with the script supplied under rubric Convert remote tags and branches to local one gave me really weird results. The tags were pointing to the wrong commit-IDs. I thought, that git-svn was to blame and reported this as bug #887881. In the following mail exchange Andreas Kaesorg explained to me, that the issue is caused by so-called mixed-revision-tags in our repository as shown in the following example:


$ svn log -v -r7405

[svn-buildpackage] Tagging shelxle 1.0.888-1
------------------------------------------------------------------------

Looking into the git log, the tags deteremined by git-svn are really not in their right place in the history line, even before running the script to convert the branches into real Git tags. So IMHO git-svn is not able to cope with this kind of situation. Because it also cannot handle our branch model, where we use /branch/package/, I began to look for different tools and found svn-all-fast-export, a tool created (by KDE?) to convert even large subversion repositories based on a ruleset. My attempt using this tool was so successful (not to speak of, how fast it is), that I want to describe it more. Maybe it will prove to be useful for others as well and it won't hurt to give some more information about this poorly documented tool :)

Step 1: Setting up a local subversion mirror

First I suggest setting up a local copy of the subversion repository to migrate, that is kept in sync with the remote repository. This can be achieved using the svnsync command. There are several howtos for this, so I won't describe this step here. Please check out this guide. In my case I have such a copy in /srv/svn/debichem.

Step 2: Creating the identity map

svn-all-fast-export needs at least two files to work. One is the so called identity map. This file contains the mapping between subversion user IDs (login names) and the (Git) committer info, like real name and mail address. The format is the same as used by git-svn:

loginname = author name <mail address>

e.g.

dleidert = Daniel Leidert <dleidert@debian.org>

The list of subversion user IDs can be obtained the same way as described in the Wiki:

svn log SVN_URL | awk -F'|' '/^r[0-9]+/ { print $2 }' | sort -u

Just replace the placeholder SVN_URL with your subversion URL. Here is the complete file for the debichem group.

Step 3: Creating the rules

The most important thing is the second file, which contains the processing rules. There is really not much documentation out there. So when in doubt, one has to read the source file src/ruleparser.cpp. I'll describe, what I already found out. If you are impatient, here is my result so far.

The basic rules are:


create repository REPOSITORY
...
end repository

and


match PATTERN
...
end match

The first rule creates a bare git repository with the name you've chosen (above represented by REPOSITORY). It can have one child, that is the repository description to be put into the repositories description file. There are AFAIK no other elements allowed here. So in case of e.g. ShelXle the rule might look like this:


create repository shelxle
description packaging of ShelXle, a graphical user interface for SHELXL
end repository

You'll have to create every repository, before you can put something into it. Else svn-all-fast-export will exit with an error. JFTR: It won't complain, if you create a repository, but don't put anything into it. You will just end up with an empty Git repository.

Now the second type of rule is the most important one. Based on regular expression match patterns (above represented by PATTERN), one can define actions, including the possibility to limit these actions to repositories, branches and revisions. The patterns are applied in their order of appearance. Thus if a matching pattern is found, other patterns matching but appearing later in the rules file, won't apply! So a special rule should always be put above a general rule. The patterns, that can be used, seem to be of type QRegExp and seem like basic Perl regular expressions including e.g. capturing, backreferences and lookahead capabilities. For a multi-package subversion repository with standard layout (that is /PACKAGE/{trunk,tags,branches}/), clean naming and subversion history, the rules could be:


match /([^/]+)/trunk/
repository \1
branch master
end match

match /([^/]+)/tags/([^/]+)/
repository \1
branch refs/tags/debian/\2
annotated true
end match

match /([^/]+)/branches/([^/]+)/
repository \1
branch \2
end match

The first rule captures the (source) package name from the path and puts it into the backreference \1. It applies to the trunk directory history and will put everything it finds there into the repository named after the directory - here we simply use the backreference \1 to that name - and there into the master branch. Note, that svn-all-fast-export will error out, if it tries to access a repository, which has not been created. So make sure, all repositories are created as shown with the create repository rule. The second rule captures the (source) package name from the path too and puts it into the backreference \1. But in backreference \2 it further captures (and applies to) all the tag directories under the /tags/ directory. Usually these have a Debian package version as name. With the branch statement as shown in this rule, the tags, which are really just branches in subversion, are automatically converted to annotated Git tags (another advantage of svn-all-fast-export over git-svn). Without enabling the annotated statement, the tags created will be lightweight tags. So the tag name (here: debian/VERSION) is determined via backreference \2. The third rule is almost the same, except that everything found in the matching path will be pushed into a Git branch named after the top-level directory captured from the subversion path.

Now in an ideal world, this might be enough and the actual conversion can be done. The command should only be executed in an empty directory. I'll assume, that the identity map is called authors and the rules file is called rules and that both are in the parent directory. I'll also assume, that the local subversion mirror of the packaging repository is at /srv/svn/mymirror. So ...

svn-all-fast-export --stats --identity-map=../authors.txt --rules=../debichem.rules --stats /srv/svn/mymirror

... will create one or more bare Git repositories (depending on your rules file) in the current directory. After the command succeeded, you can test the results ...


git -C REPOSITORY/ --bare show-ref
git -C REPOSITORY/ --bare log --all --graph

... and you will find your repositories description (if you added one to the rules file) in REPOSITORY/description:

cat REPOSITORY/description

Please note, that not all the debian version strings are well formed Git reference names and therefor need fixing. There might also be gaps shown in the Git history log. Or maybe the command didn't even suceed or complained (without you noticing it) or you ended up with an empty repository, although the matching rules applied. I encountered all of these issues and I'll describe the cause and fixes in the next blog article.

But if everything went well (you have no history gaps, the tags are in their right place within the linearized history and the repository looks fine) and you can and want to proceed, you might want to skip to the next step.

In the debichem group we used a different layout. The packaging directories were under /{unstable,experimental,wheezy,lenny,non-free}/PACKAGE/. This translates to /unstable/PACKAGE/ and /non-free/PACKAGE/ being the trunk directories and the others being the branches. The tags are in /tags/PACKAGE/. And packages, that are yet to upload are located in /wnpp/PACKAGE/. With this layout, the basic rules are:


# trunk handling
# e.g. /unstable/espresso/
# e.g. /non-free/molden/
match /(?:unstable|non-free)/([^/]+)/
repository \1
branch master
end match

# handling wnpp
# e.g. /wnpp/osra/
match /(wnpp)/([^/]+)/
repository \2
branch \1
end match

# branch handling
# e.g. /wheezy/espresso/
match /(lenny|wheezy|experimental)/([^/]+)/
repository \2
branch \1
end match

# tags handling
# e.g. /tags/espresso/VERSION/
match /tags/([^/]+)/([^/]+)/
repository \1
annotated true
branch refs/tags/debian/\2
substitute branch s/~/_/
substitute branch s/:/_/
end match

In the first rule, there is a non-capturing expression (?: ... ), which simply means, that the rule applies to /unstable/ and /non-free/. Thus the backreference \1 refers to second part of the path, the package directory name. The contents found are pushed to the master branch. In the second rule, the contents from the wnpp directory are not pushed to master, but instead to a branch called wnpp. This was necessary because of overlaps between /unstable/ and /wnpp/ history and already shows, that the repositories history makes things complicated. In the third rule, the first backreference \1 determines the branch (note the capturing expression in contrast to the first rule) and the second backreference \2 the package repository to act on. The last rule is similar, but now \1 determines the package repository and \2 the tag name (debian package version) based on the matching path. The example also shows another issue, which I'd like to explain more in the next article: some characters we use in debian package versions, e.g. the tilde sign and the colon, are not allowed within Git tag names and must therefor be substituted, which is done by the substitute branch EXPRESSION instructions.

Step 4: Cleaning the bare repository

The tool documentation suggests to run ...

git -C REPOSITORY/ repack -a -d -f

... before you upload this bare repository to another location. But Stuart Prescott told me on the debichem list, that this might not be enough and still leave some garbage behind. I'm not experienved enough to judge here, but his suggestion is, to clone the repository, either a bare clone or clone and init a new bare. I used the first approach:


git -C REPOSITORY/ --bare clone --bare REPOSITORY.git
git -C REPOSITORY.git/ repack -a -d -f

Please note, that this won't copy the repositories description file. You'll have to copy it manually, if you wanna keep it. The resulting bare repository can be uploaded (e.g. to git.debian.org as personal repository:


cp REPOSITORY/description REPOSITORY.git/description
touch REPOSITORY.git/git-daemon-export-ok
rsync -avz REPOSITORY.git git.debian.org:~/public_git/

Or you clone the repository, add a remote origin and push everything there. It is even possible to use the gitlab API at salsa.debian.org to create a project and push there. I'll save the latter for another post. If you are hasty, you'll find a script here.

An old DOS BBS in a Docker container

Planet Debian - Mër, 31/01/2018 - 12:32md

Awhile back, I wrote about my Debian Docker base images. I decided to extend this concept a bit further: to running DOS applications in Docker.

But first, a screenshot:

It turns out this is possible, but difficult. I went through all three major DOS emulators available (dosbox, qemu, and dosemu). I got them all running inside the Docker container, but had a number of, er, fun issues to resolve.

The general thing one has to do here is present a fake modem to the DOS environment. This needs to be exposed outside the container as a TCP port. That much is possible in various ways — I wound up using tcpser. dosbox had a TCP modem interface, but it turned out to be too buggy for this purpose.

The challenge comes in where you want to be able to accept more than one incoming telnet (or TCP) connection at a time. DOS was not a multitasking operating system, so there were any number of hackish solutions back then. One might have had multiple physical computers, one for each incoming phone line. Or they might have run multiple pseudo-DOS instances under a multitasking layer like DESQview, OS/2, or even Windows 3.1.

(Side note: I just learned of DESQview/X, which integrated DESQview with X11R5 and replaced the Windows 3 drivers to allow running Windows as an X application).

For various reasons, I didn’t want to try running one of those systems inside Docker. That left me with emulating the original multiple physical node setup. In theory, pretty easy — spin up a bunch of DOS boxes, each using at most 1MB of emulated RAM, and go to town. But here came the challenge.

In a multiple-physical-node setup, you need some sort of file sharing, because your nodes have to access the shared message and file store. There were a myriad of clunky ways to do this in the old DOS days – Netware, LAN manager, even some PC NFS clients. I didn’t have access to Netware. I tried the Microsoft LM client in DOS, talking to a Samba server running inside the Docker container. This I got working, but the LM client used so much RAM that, even with various high memory tricks, BBS software wasn’t going to run. I couldn’t just mount an underlying filesystem in multiple dosbox instances either, because dosbox did caching that wasn’t going to be compatible.

This is why I wound up using dosemu. Besides being a more complete emulator than dosbox, it had a way of sharing the host’s filesystems that was going to work.

So, all of this wound up with this: jgoerzen/docker-bbs-renegade.

I also prepared building blocks for others that want to do something similar: docker-dos-bbs and the lower-level docker-dosemu.

As a side bonus, I also attempted running this under Joyent’s Triton (SmartOS, Solaris-based). I was pleasantly impressed that I got it all almost working there. So yes, a Renegade DOS BBS running under a Linux-based DOS emulator in a container on a Solaris machine.

Review: My Grandmother Asked Me to Tell You She's Sorry

Planet Debian - Mër, 31/01/2018 - 5:19pd

Review: My Grandmother Asked Me to Tell You She's Sorry, by Fredrik Backman

Series: Britt-Marie #1 Translator: Henning Koch Publisher: Washington Square Copyright: 2014 Printing: April 2016 ISBN: 1-5011-1507-3 Format: Trade paperback Pages: 372

Elsa is seven, going on eight. She's not very good at it; she knows she's different and annoying, which is why she gets chased and bullied constantly at school and why her only friend is her grandmother. But Granny is a superhero, who's also very bad at being old. Her superpowers are lifesaving and driving people nuts. She made a career of being a doctor in crisis zones; now she makes a second career of, well, this sort of thing:

Or that time she made a snowman in Britt-Marie and Kent's garden right under their balcony and dressed it up in grown-up clothes so it looked as if a person had fallen from the roof. Or that time those prim men wearing spectacles started ringing all the doorbells and wanted to talk about God and Jesus and heaven, and Granny stood on her balcony with her dressing gown flapping open, shooting at them with her paintball gun

The other thing Granny is good at is telling fairy tales. She's been telling Elsa fairy tales since she was small and her mom and dad had just gotten divorced and Elsa was having trouble sleeping. The fairy tales are all about Miamas and the other kingdoms of the Land-of-Almost-Awake, where the fearsome War-Without-End was fought against the shadows. Miamas is the land from which all fairy tales come, and Granny has endless stories from there, featuring princesses and knights, sorrows and victories, and kingdoms like Miploris where all the sorrows are stored.

Granny and Miamas and the Land-of-Almost-Awake make Elsa's life not too bad, even though she has no other friends and she's chased at school. But then Granny dies, right after giving Elsa one final quest, her greatest quest. It starts with a letter and a key, addressed to the Monster who lives downstairs. (Elsa calls him that because he's a huge man who only seems to come out at night.) And Granny's words:

"Promise you won't hate me when you find out who I've been. And promise me you'll protect the castle. Protect your friends."

My Grandmother Asked Me to Tell You She's Sorry is written in third person, but it's close third person focused on Elsa and her perspective on the world. She's a precocious seven-year-old who I thought was nearly perfect (rare praise for me for children in books), which probably means some folks will think she's a little too precocious. But she has a wonderful voice, a combination of creative imagination, thoughtfulness, and good taste in literature (particularly Harry Potter and Marvel Comics). The book is all about what it's like to be seven, going on eight, with a complicated family situation and an awful time at school, but enough strong emotional support from her family that she's still full of stubbornness, curiosity, and fire.

Her grandmother's quest gets her to meet the other residents of the apartment building she lives in, turning them into more than the backdrop of her life. That, in turn, adds new depth to the fairy tales her Granny told her. Their events turn out to not be pure fabrication. They were about people, the many people in her Granny's life, reshaped by Granny's wild imagination and seen through the lens of a child. They leave Elsa surprisingly well-equipped to navigate and start to untangle the complicated relationships surrounding her.

This is where Backman pulls off the triumph of this book. Elsa's discoveries that her childhood fairy tales are about the people around her, people with a long history with her grandmother, could have been disillusioning. This could be the story of magic fading into reality and thereby losing its luster. And at first Elsa is quite angry that other people have this deep connection to things she thought were hers, shared with her favorite person. But Backman perfectly walks that line, letting Elsa keep her imaginative view of the world while intelligently mapping her new discoveries onto it. The Miamas framework withstands serious weight in this story because Elsa is flexible, thoughtful, and knows how to hold on to the pieces of her story that carry deeper truth. She sees the people around her more clearly than anyone else because she has a deep grasp of her grandmother's highly perceptive, if chaotic, wisdom, baked into all the stories she grew up with.

This book starts out extremely funny, turns heartwarming and touching, and develops real suspense by the end. It starts out as Elsa nearly alone against the world and ends with a complicated matrix of friends and family, some of whom were always supporting each other beneath Elsa's notice and some of whom are re-learning the knack. It's a beautiful story, and for the second half of the book I could barely put it down.

I am, as a side note, once again struck by the subtle difference in stories from cultures with a functional safety net. I caught my American brain puzzling through ways that some of the people in this book could still be alive and living in this apartment building since they don't seem capable of holding down jobs, before realizing this story is not set in a brutal Hobbesian jungle of all against all like the United States. The existence of this safety net plays no significant role in this book apart from putting a floor under how far people can fall, and yet it makes all the difference in the world and in some ways makes Backman's plot possible. Perhaps publishers should market Swedish literary novels as utopian science fiction in the US.

This is great stuff. The back and forth between fairy tales and Elsa's resilient and slightly sarcastic life can take a bit to get used to, but stick with it. All the details of the fairy tales matter, and are tied back together wonderfully by the end of the book. Highly recommended. In its own way, this is fully as good as A Man Called Ove.

There is a subsequent book, Britt-Marie Was Here, that follows one of the supporting characters of this novel, but My Grandmother Asked Me to Tell You She's Sorry stands alone and reaches a very satisfying conclusion (including for that character).

Debian and GNOME have both recently adopted self-hosted GitLab for their git hosting. GNOME’s service is named simply https://gitlab.gnome.org/ ; Debian’s has the more intriguing name https://salsa.debian.org/ . If you ask the Salsa sysadmins, they’ll explain that they were in a Mexican restaurant when they needed to decide on a name!

There’s a useful under-documented feature I found. If you place a logo.png in the root of your repository, it will be automatically used as the default “avatar” for your project (in other words, the logo that shows up on the web page next to your project).

I added a logo.png to GNOME Tweaks at GNOME and it automatically showed up in Salsa when I imported the new version.

Other Notes

I first tried with a symlink to my app icon, but it didn’t work. I had to actually copy the icon.

The logo.png convention doesn’t seem to be supported at GitHub currently.

Fair communication requires mutual consent

Planet Debian - Mar, 30/01/2018 - 9:33md

I was pleased to read Shirish Agarwal's blog in reply to the blog I posted last week Do the little things matter?

Given the militaristic theme used in my own post, I was also somewhat amused to see news this week of the Strava app leaking locations and layouts of secret US military facilities like Area 51. What a way to mark International Data Privacy Day. Maybe rather than inadvertently misleading people to wonder if I was suggesting that Gmail users don't make their beds, I should have emphasized that Admiral McRaven's boot camp regime for Navy SEALS needs to incorporate some of my suggestions about data privacy?

A highlight of Agarwal's blog is his comment I usually wait for a day or more when I feel myself getting inflamed/heated and I wish this had occurred in some of the other places where my ideas were discussed. Even though my ideas are sometimes provocative, I would kindly ask people to keep point 2 of the Debian Code of Conduct in mind, Assume good faith.

One thing that became clear to me after reading Agarwal's blog is that some people saw my example one-line change to Postfix's configuration as a suggestion that people need to run their own mail server. In fact, I had seen such comments before but I hadn't realized why people were reaching a conclusion that I expect everybody to run a mail server. The purpose of that line was simply to emphasize the content of the proposed bounce message, to help people understand, the receiver of an email may never have agreed to Google's non-privacy policy but if you do use Gmail, you impose that surveillance regime on them, and not just yourself, if you send them a message from a Gmail account.

Communication requires mutual agreement about the medium. Think about it another way: if you go to a meeting with your doctor and some stranger in a foreign military uniform is in the room, you might choose to leave and find another doctor rather than communicate under surveillance.

As it turns out, many people are using alternative email services, even if they only want a web interface. There is already a feature request discussion in ProtonMail about letting users choose to opt-out of receiving messages monitored by Google and send back the bounce message suggested in my blog. Would you like to have that choice, even if you didn't use it immediately? You can vote for that issue or leave your own feedback comments in there too.

Imagine the world's biggest Kanban / Scrumboard

Planet Debian - Mar, 30/01/2018 - 7:52md

Imagine a Kanban board that could aggregate issues from multiple backends, including your CalDAV task list, Bugzilla systems (Fedora, Mozilla, GNOME communities), Github issue lists and the Debian Bug Tracking System, visualize them together and coordinate your upstream fixes and packaging fixes in a single sprint.

It is not so farfetched - all of those systems already provide read access using iCalendar URLs as described in my earlier blog. There are REST APIs to manipulate most of them too. Why not write a front end to poll them and merge the content into a Kanban board view?

We've added this as a potential GSoC project using Python and PyQt.

If you'd like to see this or any of the other proposed projects go ahead, you don't need to be a Debian Developer to suggest ideas, refer a student or be a co-mentor. Many of our projects have relevance in multiple communities. Feel free to get in touch with us through the debian-outreach mailing list.

2018 and CD burning still painful

Planet Debian - Mar, 30/01/2018 - 4:27md

Ok, we are in 2018, and for the first time in ages I wanted to burn a Audio CD, and dared to think about CD_TEXT. You know what – it is hard as in impossible for a normal user. And that in 2018. Debian, you could try to do better.

Before I start I guess it is necessary to make clear that this is a newly installed system, less than a few months old. That I am as Debian Developer not completely new to system administration. Furthermore, the user trying to burn is member of the cdrom group.

The problem with most GUI frontends is that they rely on wodim, a member of the cdrkit family. And wodim itself simply doesn’t work:

$ wodim -dummy -v speed=16 dev=/dev/sr0 -audio track* wodim: No write mode specified. wodim: Assuming -tao mode. wodim: Future versions of wodim may have different drive dependent defaults. TOC Type: 0 = CD-DA wodim: Operation not permitted. Warning: Cannot raise RLIMIT_MEMLOCK limits. wodim: Resource temporarily unavailable. Cannot get mmap for 12587008 Bytes on /dev/zero. $

Yes I know, the easy solution is to make wodim setuid root, but this is not what I want. Unfortunately the – in contrast to cdrkit/wodim still in development – parent of wodim, cdrecord, works, but only because it is setuid root after a standard installation.

That is all complicated by the fact that the main front-ends are, well, broken:

  • K3b: feels like completely broken: it cannot open its own saved project files, the .inf files generated for an audio CD project are completely broken and void of any content, it hangs regularly without any response
  • Nautilus DVD/CD burning: incapable of doing Audio CDs, offers only Data cd
  • Brasero: terminates with “ejecting disc” and “An unknown error occurred”, looking at the log file it shows that again wodim is the culprit. But brasero could be a bit more helpful! Additional minus point: no cddb interface.

The only exception I found was Xfburn which managed to burn the CD without any hitch or problem. Wow – besides it doesn’t support CD_TEXT, which is also not optimal.

A solution for burning CD_TEXT

So in case you really want to burn CD_TEXT, there is at the moment, as far as I see, only one option, and that is the command line using Cdrdao. Thanks to this excellent article I managed to burn using the following command (as user, not root, nothing special):

cdrdao write --device /dev/sr0 --driver generic-mmc:0x10 -v 2 -n --eject mycd.toc

The format of the .toc file is a bit complicated but documented, see the linked article.

All in all a very depressing situation I have to say, especially for being in 2018 …

It’s my birthday (again.........). I’m 21, for the second time around. Hooray!

So far it’s been a nice day, with lots of people wishing me happy birthday from midnight last night (including a rather lovely thing from Jono). I got a cool shirt off mum and dad, which I shall be wearing for this evening’s venture to Ghetto Golf, a sort of weird crazy golf place which is all neon and skulls and graffiti, with cocktails.

Dinner with Niamh this afternoon, too, which is cool. I’m still as worried about the future and the world as I was this time last year, but I can have a day off for my birthday. And I have friends. This helps. So I can do nice things; write some code, maybe publish the talk I did at Hackference, solve a problem or two. Eat biscuits. You know. Nice things. No ironing.

Many happy returns, me.

Jono Bacon: Happy Birthday, Stuart

Planet Ubuntu - Mar, 30/01/2018 - 9:03pd

In the year 2000, I was a long-haired student enthralled with open source and Linux. I set up a Linux user group in England as a means to meet other open source people, and one evening, in strolled a red-headed gentleman. Riddled with ideas and opinions, I didn’t realize that evening that he would end up becoming my best pal.

What followed was not just a friendship, but over 15 years of collaborating together. We started LugRadio, which resulted in hundreds of episodes and multiple live shows in the UK and USA. We followed that up with Shot of Jaq, and our current podcast, Bad Voltage, which has our other partner in crime in it, Jeremy Garcia.

Outside of podcasting, we designed and built a somewhat short-lived audio multi-track audio editor, Jokosher, and countless other little ideas, prototypes, and experiments. We flew around the world to various conferences, spent literally hours on the phone debating the nuances of technology, and blew the froth off many a cold one solving the world.

It was clear that what clicked with us is that we were both captivated by a journey into this newly forming collaborative technological age and associated communities, and part of the joy was sharing this experience together.

As our friendship grew though, I realized that this wasn’t just about nerding out.

Stuart is the definition of a good person, and a great friend. He is kind, generous, warm. He brings a blunt force of logic in illogical situations and an equally blunt kindness in tough times. He has always been there for the major changes in my life, such as moving to the USA, getting married, having a kid, and switching jobs. He provides both a voice of inspiration as well as reason. He even flew to California from the UK for a weekend just to join my previous birthday (and the surprise party Erica threw).

He balances the perfect mix of hilariously forthright opinion matched with gentle nuance and care for those close to him. I have often thought of him as the entire mix of the Top Gear team: the comically opinionated Clarkson, the adventurous Hammond, the dry wit of May, and the importance of the friendship they all share.

A great talk he did about the UX of text – check it out.

This has resulted in Stuart becoming someone who is well loved by his friends, peers, and fans. He is not just a brilliant web consultant, a well-respected member of the web and open source communities, and a talented podcaster, but he is someone people want to be around, myself included.

Stuart, happy birthday. While today is a day when people typically give you gifts, I want to thank you for the gift of being such a good friend, year after year. Love you, pal, and I look forward to seeing you tweeting about how terrible the music is in the pub tonight.

Clive Johnston: New artwork for Falkon, do you have any ideas?

Planet Ubuntu - Hën, 29/01/2018 - 10:37md

This past few days there has been some interesting developments over at the Falkon project on KDE Phabricator, especially interesting is this task https://phabricator.kde.org/T6859

The lead developer has called for submissions on a new logo for Falkon.  One of the current submissions, which I must say I love, is shown below by Andres Betts who is on the KDE VDG team.

Do you have ideas on what the new logo should be?  Please head over to the task and post your ideas.

Also, if you want to help test Falkon, you can grab it from my PPA – https://launchpad.net/~clivejo/+archive/ubuntu/falkon/
