Debian Med Sprint 2020

Location, Date

• when: Feb 8/9, 2020

• where: DCSO GmbH , EUREF-Campus 22, 10829 Berlin, Germany

• Venue will be open at ~9AM, please ring the bell outside building number 22 ("DCSO" 2nd floor, main reception). If no one opens, please call organiser (+49 (0)151 54150155)

Venue

We will have access to one large (~15 people) and one small (~ 5 people) meeting room, so working in separate groups from time to time is definitely possible. A comfortable open space with coffee machine for socialising and relaxing is available.

Network and Wifi

There will be only public WiFi provided by DCSO. Sorry, no wired ethernet unless someone brings an access point and switch.

Getting there

Berlin can be easily reached from within Germany using the DB train system (Berlin Hbf or Berlin-Südkreuz) or Flixbus long-distance bus service (Berlin ZOB or Alexanderplatz). There are also two main international airports: Berlin Tegel (TXL) and Schönefeld (SXF). Both have good public transport connections to the rest of the city for typically <5 EUR per trip (TXL bus or S-Bahn S9 and S45 for SXF).

The venue is easily reachable by S-Bahn (S1, Ringbahn S41/S42/S46) via Schöneberg station. There are also a couple of buses running (M46, 248). See https://sbahn.berlin/liniennetz/station/235/ for more details. Südkreuz station would also be an alternative with a bit of walking.

Please avoid coming by car in favour of the environment and limited parking.

Accommodation

There are a variety of hotels and hostels just a couple of S-Bahn stations from the venue, e.g. near Potsdamer Platz or Anhalter Bahnhof: https://www.google.com/maps/search/hotels+near+euref-campus/@52.4884989,13.3415758,14z/data=!3m1!4b1!4m5!2m4!5m3!5m2!4m1!1i2

Agenda

(tentative/final agenda here before/after the sprint)

Steffen:

• Revisiting workflows (pigx, bcbio)
• Report on experiences with med.functional.domains semi-autobuilds
• Exchange on how Andreas' "routine-upgrade" and the nagging workflows changed my view on d/patches
• Revisiting refs to conda and bio.tools
• Collecting thoughts on our tasks pages
• Packaging load - should we prioritize? Automate? Learn from conda?
• Open Science/Med Hardware and apps in Debian

Matúš:

• Adding refs between Bioconda, Debian Med, and bio.tools; adding EDAM annotation

Olivier:

• Patch biomaj3 package to workaround python-influxdb panda ftbs issue
• Bug squashing:
  • pbsuite (done)
  • obitools (py3 port, compiles and unit tests ok, pushed to git but expects to still be buggy)
  • kinetictools (#936797): tried py3 port, but depends on pbcommand which now has a different API.
  • Investigations on opensurgsim ftbs bug(#925797): seems to be fixed, to be confirmed after cleanup and rebuild

Reports

(pointers to communication about the sprint)

• announcement: (e.g. link to lists.d.o archives)
  • Steffen+Matus: Prepared package for bash kernel for Jupyter notebooks - only to then learn about the "!" prefix
  • Export of Debian annotation and references to bio.tools (pull request pending) - with refs to conda, omictools, biii, scicrunch
  • Inspection of udd via psql - removed last RRID references
  • Steffen+Matus+Michael: Identified need for a package-landing page for non-developers
    • should give instructions how to install
    • should not confuse too much
    • should have many distribution-independent problem-solving spirits
    • ties to CWL would be nice
    • should affect Debian as a whole, Debian Med starts out with something somewhen
• report: (e.g. link to lists.d.o archives)

   3. pywnb (950936)

   4. python-biom-format (forwarded upstream 950929)

   5. python-skbio (forwarded upstream 950930)

   6. psychopy (several bugs will be fixed once python-questplus will be accepted in unstable)

   7. python-neuroshare (937945 - some remaining Python3 porting issues)

5. Setup new server for blends.debian.net

Sascha Steinbiss

1. Added autopkgtests to Vmatch and ?GenomeThreader

2. Investigates IVA FTBFS and disabled tests that need lots of RAM (KMC), will wait for rebuilds
3. Upstreamed reproducibility patches for

   1. Vmatch: https://github.com/genometools/vstree/pull/7, https://github.com/genometools/vstree/pull/6

   2. ?GenomeThreader: https://github.com/genometools/genomethreader/pull/15

4. Made Vmatch (theoretically) build on all archs (including Hurd) by setting PATH_MAX

5. Investigated non-reproducibility of ?GenomeTools and fixed it by using static graphics instead of regenerating them at build

6. Investigated non-reproducibility of lambda-align and fixed it by reverting to "Release" build mode

7. Addressed upstream issue in LTRdigest: https://github.com/genometools/genometools/pull/937

8. (a bit offtopic:) Work towards Suricata builds in Debian without vendored Rust crates
   1. Learned how to package Rust crates using debcargo
   2. Package 6 dependencies as crates not in unstable yet
   3. Made sure these are used in the build
9. Inquired about the state of Debian Med's Twitter account
