Gregor Herrmann: teamwork in practice

teamwork, or: why I love the Debian Perl Group: elbrus has introduced a (very untypical) package into the Debian Perl Group in 2022. after changes of the default compiler options (-Werror=implicit-function-declaration) in debian, it didn't build any more & received an RC bug. because I sometimes like challenges, I had a look at it & cobbled together a patch. as I hardly speak any C, I sent my notes to the bug report & (implictly) asked for help. & went out to meet a friend. when I came home, I found an email from ntyni, sent less than 2 hours after my mail, where he friendly pointed out the issues with my patch & sent a corrected version. all I needed to do was to adjust the patch & upload the package. one more bug fixed, one less task for us, & elbrus can concentrate on more important tasks :)
thanks again, niko!

Gregor Herrmann: demo video: dpt(1) in pkg-perl-tools

in the Debian Perl Group we are maintaining a lot of packages (around 4000 at the time of writing). this also means that we are spending some time on improving our tools which allow us to handle this amount of packages in a reasonable time. many of the tools are shipped in the pkg-perl-tools package since 2013, & lots of them are scripts which are called as subcommands of the dpt(1) wrapper script. in the last years I got the impression that not all team members are aware of all the useful tools, & that some more promotion might be called for. & last week I was in the mood for creating a short demo video to showcase how I use some dpt(1) subcommands when updating a package to a new upstream release. (even though I prefer text over videos myself :)) probably not a cinematographic masterpiece but as the feedback of a few viewers has been positive, I'm posting it here as well: (direct link as planets ignore iframes )

Jonathan Dowland: Broken webcam aspect ratio

picture of my Sony RX100-III camera Sony RX100-III, relegated to a webcam
Sometimes I have remote meetings with Google Meet. Unlike the other video-conferencing services that I use (Bluejeans, Zoom), my video was stretched out of proportion under Google Meet with Firefox. I haven't found out why this was happening, but I did figure out a work-around. Thanks to Daniel Silverstone, Rob Kendrick, Gregor Herrmann and Ben Allen for pointing me in the right direction! Hardware The lovely Sony RX-100 mk3 that I bought in 2015 has spent most of its life languishing unused. During the Pandemic, once I was working from home all the time, I decided to press-gang it into service as a better-quality webcam. Newer models of this camera the mark 4 onwards have support for a USB mode called "PC Remote", which effectively makes them into webcams. Unfortunately my mark 3 does not support this, but it does have HDMI out, so I picked up a cheap "HDMI to USB Video Capture Card" from eBay. Video modes
Before: wrong aspect ratio Before: wrong aspect ratio
This device offers a selection of different video modes over a webcam interface. I used qv4l2 to explore the different modes. It became clear that the camera was outputting a signal at 16:9, but the modes on offer from the dongle were for a range of different aspect ratios. The picture for these other ratios was not letter or pillar-boxed, but stretched to fit. I also noticed that the modes which had the correct aspect ratio were at very low framerates: 1920x1080@5fps, 1360x768@8fps, 1280x720@10fps. It felt to me that I would look unnatural at such a low framerate. The most promising mode was close to the right ratio, 720x480 and 30 fps. Software
After: corrected aspect ratio After: corrected aspect ratio
My initial solution is to use the v4l2loopback kernel module, which provides a virtual loop-back webcam interface. I can write video data to it from one process, and read it back from another. Loading it as follows:
modprobe v4l2loopback exclusive_caps=1
The option exclusive_caps configures the module into a mode where it initially presents a write-only interface, but once a process has opened a file handle, it then switches to read-only for subsequent processes. Assuming there are no other camera devices connected at the time of loading the module, it will create /dev/video0.1 I experimented briefly with OBS Studio, the very versatile and feature-full streaming tool, which confirmed that I could use filters on the source video to fix the aspect ratio, and emit the result to the virtual device. I don't otherwise use OBS, though, so I achieve the same result using ffmpeg:
fmpeg -s 720x480 -i /dev/video1 -r 30 -f v4l2 -vcodec rawvideo \
    -pix_fmt yuyv422 -s 720x405 /dev/video0
The source options are to select the source video mode I want. The codec and pixel formats are to match what is being emitted (I determined that using ffprobe on the camera device). The resizing is triggered by supplying a different size to the -s parameter. I think that is equivalent to explicitly selecting a "scale" filter, and there might be other filters that could be used instead (to add pillar boxes for example). This worked just as well. In Google Meet, I select the Virtual Camera, and Google Meet is presented with only one video mode, in the correct aspect ratio, and no configurable options for it, so it can't misbehave. Future I'm planning to automate the loading (and unloading) of the module and starting the ffmpeg process in response to the real camera device being plugged or unplugged, using systemd events and services. (I don't leave the camera plugged in all the time due to some bad USB behaviour I've experienced if I do so.) If I get that working, I will write a follow-up.

  1. you can request a specific device name/number with another module option.

Chris Lamb: Lintian: We are all Perl developers now

Lintian is a static analysis tool for Debian packages, reporting on various errors, omissions and general quality-assurance issues to maintainers. I've previously written about my exploits with Lintian as well as authoring a short tutorial on how to write your own Lintian check. Anyway, I recently uploaded version 2.5.53 about two months since previous release. The biggest changes you may notice are supporting the latest version of the Debian Policy as well the addition of checks to encourage the migration to Python 3. Thanks to all who contributed patches, code review and bug reports to this release. The full changelog is as follows:

Gregor Herrmann: RC bugs 2017/08-29

long time no blog post. & the stretch release happened without many RC bug fixes from me; in practice, the auto-removals are faster & more convenient. what I nevertheless did in the last months was to fix RC bugs in pkg-perl packages (it still surprises me how fast rotting & constantly moving code is); prepare RC bug fixes for jessie (also for pkg-perl packages); & in the last weeks provide patches & carry out NMUs for perl packages as part of the ongoing perl 5.26 transition.

Gregor Herrmann: RC bugs 2016/52-2017/07

debian is in deep freeze for the upcoming stretch release. still, I haven't dived into fixing "general" release-critical bugs yet; so far I mostly kept to working on bugs in the debian perl group: thanks to the release team for pro-actively unblocking the packages with fixes which were uploaded after the begin of the freeze!

Mike Gabriel: UIF bug: Caused by flawed IPv6 DNS resolving in Perl's NetAddr::IP

TL;DR; If you use NetAddr::IP->new6() for resolving DNS names to IPv6 addresses, the addresses returned by NetAddr::IP are not what you might expect. See below for details. Issue #2 in UIF Over the last couple of days, I tried to figure out the cause of a weird issue observed in UIF (Universal Internet Firewall [1], a nice Perl tool for setting up ip(6)tables based Firewalls). Already a long time ago, I stumbled over a weird DNS resolving issue of DNS names to IPv6 addresses in UIF that I reported as issue #2 [2] against upstream UIF back then. I happen to be co-author of UIF. So, I felt very ashamed all the time for not fixing the issue any sooner. As many of us DDs try to get our packages into shape before the next Debian release these days, I find myself doing the same. I started investigating the underlying cause of issue #2 in UIF a couple of days ago. Issue #119858 on CPAN Today, I figured out that the Perl code in UIF is not causing the observed phenomenon. The same behaviour is reproducible with a minimal and pure NetAddr::IP based Perl script (reported as Debian bug #851388 [2]. Thanks to Gregor Herrmann for forwarding Debian bug upstream (#119858 [3]). Here is the example script that shows the flawed behaviour:
#!/usr/bin/perl
use NetAddr::IP;
my $hostname = "google-public-dns-a.google.com";
my $ip6 = NetAddr::IP->new6($hostname);
my $ip4 = NetAddr::IP->new($hostname);
print "$ip6 <- WTF???\n";
print "$ip4\n";
exit(0);
... gives...
[mike@minobo ~]$ ./netaddr-ip_resolv-ipv6.pl
0:0:0:0:0:0:808:808/128 <- WTF???
8.8.8.8/32
In words... So what happens in NetAddr::IP is that with the new6() "constructor" you initialize a new IPv6 address. If the address is a DNS name, NetAddr::IP internally resolves it into an IPv4 address and converts this IPv4 address into some IPv6'ish format. This bogus IPv6 address is not the one matching the given DNS name. Impacted Software in Debian Various Debian packages use NetAddr::IP and may be affected by this flaw, here is an incomplete list (use apt-rdepends -r libnetaddr-ip-perl for the complete list): Any of the above packages could be affected if NetAddr::IP->new6(<dnsname>) is being used. I haven't checked any of the code bases, but possibly the corresponding maintainers may want to do that. References light+love

Reproducible builds folks: Reproducible Builds: week 75 in Stretch cycle

What happened in the Reproducible Builds effort between Sunday September 25 and Saturday October 1 2016: Statistics For the first time, we reached 91% reproducible packages in our testing framework on testing/amd64 using a determistic build path. (This is what we recommend to make packages in Stretch reproducible.) For unstable/amd64, where we additionally test for reproducibility across different build paths we are at almost 76% again. IRC meetings We have a poll to set a time for a new regular IRC meeting. If you would like to attend, please input your available times and we will try to accommodate for you. There was a trial IRC meeting on Friday, 2016-09-31 1800 UTC. Unfortunately, we did not activate meetbot. Despite this participants consider the meeting a success as several topics where discussed (eg changes to IRC notifications of tests.r-b.o) and the meeting stayed within one our length. Upcoming events Reproduce and Verify Filesystems - Vincent Batts, Red Hat - Berlin (Germany), 5th October, 14:30 - 15:20 @ LinuxCon + ContainerCon Europe 2016. From Reproducible Debian builds to Reproducible OpenWrt, LEDE & coreboot - Holger "h01ger" Levsen and Alexander "lynxis" Couzens - Berlin (Germany), 13th October, 11:00 - 11:25 @ OpenWrt Summit 2016. Introduction to Reproducible Builds - Vagrant Cascadian will be presenting at the SeaGL.org Conference In Seattle (USA), November 11th-12th, 2016. Previous events GHC Determinism - Bartosz Nitka, Facebook - Nara (Japan), 24th September, ICPF 2016. Toolchain development and fixes Michael Meskes uploaded bsdmainutils/9.0.11 to unstable with a fix for #830259 based on Reiner Herrmann's patch. This fixed locale_dependent_symbol_order_by_lorder issue in the affected packages (freebsd-libs, mmh). devscripts/2.16.8 was uploaded to unstable. It includes a debrepro script by Antonio Terceiro which is similar in purpose to reprotest but more lightweight; specific to Debian packages and without support for virtual servers or configurable variations. Packages reviewed and fixed, and bugs filed The following updated packages have become reproducible in our testing framework after being fixed: The following updated packages appear to be reproducible now for reasons we were not able to figure out. (Relevant changelogs did not mention reproducible builds.) Some uploads have addressed some reproducibility issues, but not all of them: Patches submitted that have not made their way to the archive yet: Reviews of unreproducible packages 77 package reviews have been added, 178 have been updated and 80 have been removed in this week, adding to our knowledge about identified issues. 6 issue types have been updated: Weekly QA work As part of reproducibility testing, FTBFS bugs have been detected and reported by: diffoscope development A new version of diffoscope 61 was uploaded to unstable by Chris Lamb. It included contributions from: Post-release there were further contributions from: reprotest development A new version of reprotest 0.3.2 was uploaded to unstable by Ximin Luo. It included contributions from: Post-release there were further contributions from: tests.reproducible-builds.org Misc. This week's edition was written by Ximin Luo, Holger Levsen & Chris Lamb and reviewed by a bunch of Reproducible Builds folks on IRC.

Reproducible builds folks: Reproducible Builds: week 71 in Stretch cycle

What happened in the Reproducible Builds effort between Sunday August 28 and Saturday September 3 2016: Media coverage Antonio Terceiro blogged about testing build reprodubility with debrepro . GSoC and Outreachy updates The next round is being planned now: see their page with a timeline and participating organizations listing. Maybe you want to participate this time? Then please reach out to us as soon as possible! Packages reviewed and fixed, and bugs filed The following packages have addressed reproducibility issues in other packages: The following updated packages have become reproducible in our current test setup after being fixed: The following updated packages appear to be reproducible now, for reasons we were not able to figure out yet. (Relevant changelogs did not mention reproducible builds.) The following 4 packages were not changed, but have become reproducible due to changes in their build-dependencies: Some uploads have addressed some reproducibility issues, but not all of them: Patches submitted that have not made their way to the archive yet: Reviews of unreproducible packages 706 package reviews have been added, 22 have been updated and 16 have been removed in this week, adding to our knowledge about identified issues. 5 issue types have been added: 1 issue type has been updated: Weekly QA work FTBFS bugs have been reported by: diffoscope development diffoscope development on the next version (60) continued in git, taking in contributions from: strip-nondeterminism development Mattia Rizzolo uploaded strip-nondeterminism 0.023-2~bpo8+1 to jessie-backports. A new version of strip-nondeterminism 0.024-1 was uploaded to unstable by Chris Lamb. It included contributions from: Holger added jobs on jenkins.debian.net to run testsuites on every commit. There is one job for the master branch and one for the other branches. disorderfs development Holger added jobs on jenkins.debian.net to run testsuites on every commit. There is one job for the master branch and one for the other branches. tests.reproducible-builds.org Debian: We now vary the GECOS records of the two build users. Thanks to Paul Wise for providing the patch. Misc. This week's edition was written by Ximin Luo, Holger Levsen & Chris Lamb and reviewed by a bunch of Reproducible Builds folks on IRC.

Gregor Herrmann: RC bugs 2016/30-33

not much to report but I got at least some RC bugs fixed in the last weeks. again mostly perl stuff:

Gregor Herrmann: RC bugs 2016/01-29

seems I've neglected both my blog & my RC bug fixing activities in the last months. anyway, since I still keep track of RC bugs I worked on, I thought I might as well publish the list:

Reproducible builds folks: Reproducible builds: week 62 in Stretch cycle

What happened in the Reproducible Builds effort between June 26th and July 2nd 2016: Read on to find out why we're lagging some weeks behind ! GSoC and Outreachy updates Toolchain fixes With the doxygen upload we are now down to only 2 modified packages in our repository: dpkg and rdfind. Weekly reports delay and the future of statistics To catch up with our backlog of weekly reports we have decided to skip some of the statistics for this week. We might publish them in a future report, or we might switch to a format where we summarize them more (and which we can create (even) more automatically), we'll see. We are doing these weekly statistics because we believe it's appropriate and useful to credit people's work and make it more visible. What do you think? We would love to hear your thoughts on this matter! Do you read these statistics? Somewhat? Actually, thanks to the power of notmuch, Holger came up with what you can see below, so what's missing for this week are the uploads fixing irreprodubilities. Which we really would like to show for the reasons stated above and because we really really need these uploads to happen ;-) But then we also like to confirm the bugs are really gone, which (atm) requires manual checking, and to look for the words "reproducible" and "deterministic" (and spelling variations) in debian/changelogs of all uploads, to spot reproducible work not tracked via the BTS. And we still need to catch up on the backlog of weekly reports. Bugs submitted with reproducible usertags It seems DebCamp in Cape Town was hugely successful and made some people get a lot of work done: 61 bugs have been filed with reproducible builds usertags and 60 of them had patches: Package reviews 437 new reviews have been added (though most of them were just linking the bug, "only" 56 new issues in packages were found), an unknown number has been been updated and 60 have been removed in this week, adding to our knowledge about identified issues. 4 new issue types have been found: Weekly QA work 98 FTBFS bugs have been reported by Chris Lamb and Santiago Vila. diffoscope development strip-nondeterminism development tests.reproducible-builds.org Misc. This week's edition was written by Mattia Rizzolo, Reiner Herrmann, Ceridwen and Holger Levsen and reviewed by a bunch of Reproducible builds folks on IRC.

Lunar: Reproducible builds: week 45 in Stretch cycle

What happened in the reproducible builds effort between February 28th and March 5th:

Toolchain fixes
  • Antonio Terceiro uploaded gem2deb/0.27 that forces generated gemspecs to use the date from debian/changelog.
  • Antonio Terceiro uploaded gem2deb/0.28 that forces generated gemspecs to have their contains file lists sorted.
  • Robert Luberda uploaded ispell/3.4.00-5 which make builds of hashes reproducible.
  • C dric Boutillier uploaded ruby-ronn/0.7.3-4 which will make the output locale agnostic. Original patch by Chris Lamb.
  • Markus Koschany uploaded spring/101.0+dfsg-1. Fixed by Alexandre Detiste.
Ximin Luo resubmitted the patch adding the --clamp-mtime option to Tar on Savannah's bug tracker. Lunar rebased our experimental dpkg on top of the current master branch. Changes in the test infrastructure are required before uploading a new version to our experimental repository. Reiner Herrmann rebased our custom texlive-bin against the latest uploaded version.

Packages fixed The following 77 packages have become reproducible due to changes in their build dependencies: asciidoctor, atig, fuel-astute, jekyll, libphone-ui-shr, linkchecker, maven-plugin-testing, node-iscroll, origami-pdf, plexus-digest, pry, python-avro, python-odf, rails, ruby-actionpack-xml-parser, ruby-active-model-serializers, ruby-activerecord-session-store, ruby-api-pagination, ruby-babosa, ruby-carrierwave, ruby-classifier-reborn, ruby-compass, ruby-concurrent, ruby-configurate, ruby-crack, ruby-css-parser, ruby-cucumber-rails, ruby-delorean, ruby-encryptor, ruby-fakeweb, ruby-flexmock, ruby-fog-vsphere, ruby-gemojione, ruby-git, ruby-grack, ruby-htmlentities, ruby-jekyll-feed, ruby-json-schema, ruby-listen, ruby-markerb, ruby-mathml, ruby-mini-magick, ruby-net-telnet, ruby-omniauth-azure-oauth2, ruby-omniauth-saml, ruby-org, ruby-origin, ruby-prawn, ruby-pygments.rb, ruby-raemon, ruby-rails-deprecated-sanitizer, ruby-raindrops, ruby-rbpdf, ruby-rbvmomi, ruby-recaptcha, ruby-ref, ruby-responders, ruby-rjb, ruby-rspec-rails, ruby-rspec, ruby-rufus-scheduler, ruby-sass-rails, ruby-sass, ruby-sentry-raven, ruby-sequel-pg, ruby-sequel, ruby-settingslogic, ruby-shoulda-matchers, ruby-slack-notifier, ruby-symboltable, ruby-timers, ruby-zip, ticgit, tmuxinator, vagrant, wagon, yard. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues, but not all of them: Patches submitted which have not made their way to the archive yet:
  • #816209 on elog by Reiner Herrmann: use printf instead of echo which is shell-independent.
  • #816214 on python-pip by Reiner Herrmann: removes timestamp from generated Python scripts.
  • #816230 on rows by Reiner Herrmann: tell grep to always treat the input as text.
  • #816232 on eficas by Reiner Herrmann: use printf instead of echo which is shell-independent.
Florent Daigniere and bancfc reported that linux-grsec was currently built with GRKERNSEC_RANDSTRUCT which will prevent reproducible builds with the current packaging.

tests.reproducible-builds.org pbuilder has been updated to the last version to be able to support Build-Depends-Arch and Build-Conflicts-Arch. (Mattia Rizzolo, h01ger) New package sets have been added for Subgraph OS, which is based on Debian Stretch: packages and build dependencies. (h01ger) Two new armhf build nodes have been added (thanks Vagrant Cascadian) and integrated in our Jenkins setup with 8 new armhf builder jobs. (h01ger)

strip-nondeterminism development strip-nondeterminism version 0.016-1 was released on Sunday 28th. It will now normalize the POT-Creation-Date field in GNU Gettext .mo files. (Reiner Herrmann) Several improvements to the packages metadata have also been made. (h01ger, Ben Finney)

Package reviews 185 reviews have been removed, 91 added and 33 updated in the previous week. New issue: fileorder_in_gemspec_files_list. 43 FTBFS bugs were reported by Chris Lamb, Martin Michlmayr, and gregor herrmann.

Misc. After merging the patch from Dhiru Kholia adding support for SOURCE_DATE_EPOCH in rpm, Florian Festi opened a discussion on the rpm-ecosystem mailing list about reproducible builds. On March 4th, Lunar gave an overview of the general reproducible builds effort at the Internet Freedom Festival in Valencia.
