Currently Chromium will generate its Web App shortcuts by pointing to the current unwrapped executable of itself. This leads to all Web App shortcuts failing to launch as it is not launched trough nixpkgs's wrapper. This fix will set the `CHROME_WRAPPER` environment variable to point to a valid wrapper script, allowing chromium based browsers to generate valid `.desktop` files. NOTE: As these files are only set once by the browser inside of `~/.local/share/applications` and not updated, this fix will only work for generating new shortcuts, and only work as long as the relevant binary is available in `$PATH` for that user. INFO: While generic sounding, `CHROME_WRAPPER` is only invoked inside of `web_app_shortcut_linux.cc`[^1], so it should only affect the generation of web app shortcut files. INFO: There is a similar patch for google-chrome itself in nixpkgs.[^2] [^1]: https://source.chromium.org/chromium/chromium/src/+/main:chrome/browser/shell_integration_linux.cc;l=405;drc=b8f43a4e55639b03f76eccc6f6b951f2d06b8833 [^2]: https://github.com/NixOS/nixpkgs/pull/155430/ |

Maintainers
- Note: We could always use more contributors, testers, etc. E.g.:
- A dedicated maintainer for the NixOS stable channel
- PRs with cleanups, improvements, fixes, etc. (but please try to make reviews as easy as possible)
- People who handle stale issues/PRs
- Primary maintainer (responsible for all updates): @primeos
- Testers (test all stable channel updates)

Updating Chromium
Simply run ./pkgs/applications/networking/browsers/chromium/update.py
to
update upstream-info.json
. After updates it is important to test at least
nixosTests.chromium
(or basic manual testing) and google-chrome
(which
reuses upstream-info.json
).
Note: The source tarball is often only available a few hours after the release was announced. The CI/CD status can be tracked here:
- https://ci.chromium.org/p/infra/builders/cron/publish_tarball
- https://ci.chromium.org/p/infra/builders/cron/publish_tarball_dispatcher
To run all automated NixOS VM tests for Chromium, ungoogled-chromium, and Google Chrome (not recommended, currently 6x tests!):
nix-build nixos/tests/chromium.nix
A single test can be selected, e.g. to test ungoogled-chromium
(see
channelMap
in nixos/tests/chromium.nix
for all available options):
nix-build nixos/tests/chromium.nix -A ungoogled
(Note: Testing Google Chrome requires export NIXPKGS_ALLOW_UNFREE=1
.)
For custom builds it's possible to "override" channelMap
.
Backports
All updates are considered security critical and should be ported to the stable
channel ASAP. When there is a new stable release the old one should receive
security updates for roughly one month. After that it is important to mark
Chromium as insecure (see 69e4ae56c4
for an example; it is important that the
tested job still succeeds and that all browsers that use upstream-info.json
are marked as insecure).
Major version updates
Unfortunately, Chromium regularly breaks on major updates and might need various patches. Either due to issues with the Nix build sandbox (e.g. we cannot fetch dependencies via the network and do not use standard FHS paths) or due to missing upstream fixes that need to be backported.
Good sources for such patches and other hints:
- https://github.com/archlinux/svntogit-packages/tree/packages/chromium/trunk
- https://gitweb.gentoo.org/repo/gentoo.git/tree/www-client/chromium
- https://src.fedoraproject.org/rpms/chromium/tree/master
If the build fails immediately due to unknown compiler flags this usually means that a new major release of LLVM is required.
Beta and Dev channels
Those channels are only used to test and fix builds in advance. They may be broken at times and must not delay stable channel updates.
Testing
Useful tests:
- Version: chrome://version/
- GPU acceleration: chrome://gpu/
- Essential functionality: Browsing, extensions, video+audio, JS, ...
- WebGL: https://get.webgl.org/
- VA-API: https://wiki.archlinux.org/index.php/chromium#Hardware_video_acceleration
- Optional: Widevine CDM (proprietary), Benchmarks, Ozone, etc.
