FreeBSD mini-Developer Summit, February 2019

Brussels, Belgium. February 1st, 2019.

This invitation-only FreeBSD Developer Summit takes place the day before FOSDEM 2019, located in Brussels, Belgium. FreeBSD committers are welcome to register themselves; non-committers have to be sponsored by a committer to attend.

FOSDEM 2019

FOSDEM 2019 takes place on February 2nd and 3rd, 2019. Note that the FreeBSD mini-developer summit is organized independently from FOSDEM. The FreeBSD Foundation has agreed to sponsor parts of this mini-devsummit. Consider making a donation to help support events like this.

Travel Information

The FOSDEM Practical page has a lot of information about how to get to Brussels for FOSDEM.

Approaching the Event site

The DevSummit will be held in central Brussels.

The DevSummit will take place in the NH Carrefour de L'Europe hotel. Enter the hotel lobby and take the stairs next to the elevator down to level -3. Signs will show you which room the FreeBSD Developer Summit will be held in. The address is Rue du Marché aux Herbes 110, B-1000 Brussels. This is on the Place d'Espagne, just between the Grand'Place and the Central Station.

From the Central Station:

The hotel website has more instructions.

Notes

If you are in trouble with preparing your slides, you could use the template attached to the page. It contains a LaTeX source file that you can modify to create PDF slides for the FreeBSD Developer Summit. It uses the Beamer class which is an easy-to-use extension to LaTeX for making presentations. You can easily install it by the following command (as root):

# pkg install latex-beamer

This will install Beamer and pdfLaTeX that can be used for compiling the sources to produce the desired PDF file.

$ pdflatex my-presentation.latex

Or you can use the LibreOffice / OpenOffice template (contributed by BaptisteDaroussin).

A few rule-of-thumbs when creating slides:

Contact devsummit@FreeBSD.org if you have questions or problems.

Registration

In order to attend, you must register in advance using our registration system; this allows us to size rooms, order food, provide beverages, and make dinner reservations. We appreciate your cooperation in letting us know your plans well in advance of the event. Non-committers must be sponsored by a committer in order to attend.

The meeting room and refreshments during the DevSummit will be sponsored. We collect a small fee rom attendees to help cover the costs. The dinner will have to be paid by the attendees themselves (at the dinner).

Here is a list of the attendees and their guests at the summit.

Intros

Last minute additions to the agenda

rodrigo asks around if anyone is using his pkg-provides plugin and if there are any issues

manu@ presenting about the pinebook, graphics on arm64, pinephone, pinetab (no video support at all yet, no framebuffer)(https://www.pine64.org)

GSoC

Mahdi briefly presents his GSoC 2019 idea: Linux netlink drivers, more GSoC admins needed, add ideas (https://wiki.freebsd.org/SummerOfCode), gsoc mentors IRC channel: #gsoc-mentors, GSoC-FAQ
Going through the idea list to see what’s still needed
Review of existing list
Kernel sanitizers probably already in progress.
Check if bhyve is still needed
Check with imp@ on PNP_INFO items
IPv6 userland cleanup project needs more definition; “cleanup work” may not be a great project. However, if it can be re-phrased as a “new feature” project, that may fit better.
Rewrite “Audit base for read-only and NFS Mount Compatibility”: read-only works and is regularly tested by enough users; does NFS testing level need to be re-evaluated after recent PNFS re-write?
Add Li-wen to MFSBSD release-building project?
Fill in ports section with items from the ports wish-list?
Add kp@ as mentor to Network Configuration Libraries project
New ideas
Netlink API (Freifunk?)
Possibly add kernel code coverage, if manageable for SoC project
Electron?
$850 bounty: https://www.bountysource.com/issues/29075473-add-freebsd-support-to-electron
pf/ipfw tests
Config/control libraries: libifconfig, libnetstat, libipfw, etc.
Followed by Python, etc. bindings?
Needs to be broken into smaller chunks; for example, add specific features to libifconfig
Convert existing shell tools to use the libraries
Example project: Add <fill in the blank> features to libifconfig and convert ifconfig to use the libifconfig implementation
Let students propose additional projects

Running and testing -CURRENT ensures the problems are identified while the work is still fresh in everyones head.

Oxybiodegradable pens are a thing

Bug Busting discussion:

Release cycles too long to get user exposure for features and after a release, there seems to be spike in bug reports from users. Shorter cycles would give quicker feedback.

Have actionable bug reports not just “it’s broken”

Script to collect information (anonymizing it) about a system, whose output must be attached to any kind of bug report -> kp@, gonzo@

Size swap partition according to available RAM for (compressed) kernel crash dumps or default to 8 GB; fallback to textdumps instead of panicing if there is not enough space to dump, aggregate the backtraces somewhere (ask backtrace.io folks if they can do it for us?)

Telemetry

Make problems more actionable, easier to pick up problems with spare time

Distinguish between actual bugs and feature requests -> filter those by labels in bugzilla

Schema change for the bugzill a tables for mandatory tables for supported release, automatically close the PRs that don’t match those releases anymore (with a message to submitter to re-submit if it’s still valid); be careful with auto-closing automation, should automatically go to “needs reproduction” queue - transits to “closed” or “responded” state after a timeout (something like 2 weeks, 1 month, 2 months, etc. without a response)

Office hours for bugs in a specific state or category

Patches should go into Phabricator (better integration between the tools), automatically open a review with reference to the bug ID

Bugathons, bugbusting sessions (2h) at devsummits in small groups to look at bugs and decide what to do with them

BSoC to create extensions for FreeBSD’s bugzilla

Bugzilla christmas crackers containing a bug ID, bingo cards, have hacktoberfest-like contests

Rodrigo talking about the ports conflicts scanner (http://pkg-provides.osorio.me/conflicts/), feasibility of integrating it with portlint is discussed, part of poudriere?

manu@ is interested in automated FreeBSD installs by reading a config file
