Tyrian

• New Tyrian based on bootstrap V4 should be tested...
  • Review wiki write up by Arzano.
• Devmanual should be added to the sites drop down menu...

Bound to fail

Using too high a MAKEOPS value and --jobs set to 4, this is a bad idea, even if you do have an 8 core Ryzen system with 32 GiBs of memory. In the example below the following default values are set in make.conf:

FILE /etc/portage/make.conf

MAKEOPTS="-j14"
EMERGE_DEFAULT_OPTS="--jobs=4 --keep-going=y"

root #emerge --update --deep --newuse --changed-deps=y --with-bdeps=y --verbose --keep-going=y --tree --backtrack=2000 --verbose-conflicts @world

>>> Emerging (1 of 205) www-client/firefox-72.0.2::gentoo
>>> Emerging (2 of 205) mail-client/thunderbird-68.4.2::gentoo
>>> Emerging (3 of 205) www-client/chromium-80.0.3987.87::gentoo
>>> Emerging (4 of 205) app-office/libreoffice-6.3.4.2::gentoo

The previous example is bound to result in job failure output similar to the following:

>>> Emerging (3 of 205) www-client/chromium-80.0.3987.87::gentoo
>>> Jobs: 0 of 205 complete, 4 running            Load avg: 21.0, 29.6, 38.7Exception in callback PipeLogger._output_handler(13)

The fastest solution

Run CTRL+c to close the Python interpreter, then do whatever is appropriate to obtain more disk space. Typically this can look like running Template:Eclean and purging any failed compilations from Portage's tmp directory:

root #eclean -d distfiles

root #eclean -d distfiles

root #rm -rfv /var/tmp/portage/*

Finally, resuming the emerge with a smaller MAKEOPTS or jobs value (or both!) should work around the build failure:

root #MAKEOPTS="-j8" emerge --resume --jobs=1

Building stages with clang

Reddit discussion here.

This Debian sites keeps a nice list of packages that are successfully built with LLVM/Clang.

Graphics stack debugging

• Write an in-depth article on debugging a present day graphics stack on Linux. Cover areas such as:
  • Screen tearing tests.
  • Debugging variables.
  • Hardware acceleration vs. software acceleration.

Wireless

Be more clear about necessary binary blob firmware for various Wi-Fi chipsets (especially the Intel iwlwifi variants).

Add information on enabling FreeSync on AMDGPU

• AMDGPU

Resolve PPC bootloader installation instructions

Handbook probably needs to be migrated from yaboot to GRUB2. See discussion on Handbook_Talk:PPC/Installation/Bootloader.

Add networking setup example to the Handbooks using ip command

Transision the Handbook to use the ip command with CIDR format rather than ifconfig.

Finish new Gentoo wallpapers

• Add new wallpapers to www.g.o.
• Work on getting a resize script for common supported display resolutions.
  • Consider mobile device resolutions.
• Upload wallpapers sources (with attribution) to Gentoo's GitHub and gitweb.g.o.
• Finish imagemagick resize script for end user reproducability.
  • See this tutorial for possible options.
  • Pseudo-code from Robin: $SRC -> parallel(for each $RESOLUTIONS[]: resample, render signet at $POS; save)

Terminology update: Overlay -> ebuild repository

Figure out how to address the following articles (man pages will also need updated):

Layman references:

• PORTDIR_OVERLAY variable.
• layman-overlay-maker command.

Add new recentchanges bot to #gentoo-wiki

Investigate: https://wikitech.wikimedia.org/wiki/EventStreams

Right now I'm researching mw-bot (source).

Code for a similar recentchanges output:

$wiki $encoded_wiki_page $action $fullurl - User: $username - Summary: $summary

Waiting on a response to issue 62 to add a new wiki to the bot's @recentchanges command.

• Setting up ircII with recentchanges: https://wikitech.wikimedia.org/wiki/IRCD#How_to_do_it_on_your_own_server

TODO: write a module to watch recent changes for sopel.

Close all open discussions in the Handbook namespace

As I continue to clean up our docs in 2017, I am rapidly working to close out all open discussions in the Handbook namespace. Will move this section to Completed tasks when finished.

Someone please work on these. Someone. ANYONE?! PLEASE!!

• GitLab - Clean up article: meld it into proper article layout/formatting according to wiki Guidelines, review for correctness.
  • Work on bringing GitLab to Gentoo. This would be of use to infra as a GitHub fall back (since GitHub isn't nicely open source).
  • Start with a Gentoo-based container (if necessary), and build from there.
