Chromium 86.0.4240.75 builds fine without this patch. And since
WEBP_MAX_DIMENSION is the same in the system libwebp this patch should
not be required anymore (it was introduced in 06ec2a9f19, apparently to
fix the build).
By default GN produces a build with all of the debug assertions enabled (is_debug=true) and including full debug info (symbol_level=2). Setting symbol_level=1 will produce enough information for stack traces, but not line-by-line debugging. Setting symbol_level=0 will include no debug symbols at all. Either will speed up the build compared to full symbols.
This is done to avoid driver specific issues and restores the previous
behaviour. Like before video acceleration can be enabled without having
to rebuild Chromium.
This will additionally install the following files:
libEGL.so libGLESv2.so
libVkICD_mock_icd.so libvk_swiftshader.so libvulkan.so
libEGL.so and libGLESv2.so are required to fix our ANGLE support.
The rest should help with the Vulkan support (currently an experimental
feature that is disabled by default).
update.nix was a huuuuge hack, abusing checksum collisions, etc., and
was extremely difficult to read and maintain, especially because
values from update.nix were also used in the derivations themselves!
I've replaced this with an implementation in Python, which I chose for
readability. Rather than generating Nix, I chose to
generate JSON, since Python can do that in the standard library and
Nix can read it.
I also set update.py as an updateScript, so Chromium can now
automatically be updated!
Fixes: https://github.com/NixOS/nixpkgs/issues/89635
Note: The following might also need to be updated:
substituteStream(): WARNING: pattern '/usr/share/xcb' doesn't match anything in file 'ui/gfx/x/BUILD.gn'
I didn't look into this yet but IIRC M86 will finally have a flag for
Linux to enable VA-API. So we shouldn't need
enable-video-acceleration-on-linux.patch anymore.
But we likely need to update enable-vdpau-support-for-nvidia.patch
when/before M86 hits the stable channel if we want to keep VDPAU
support.
Ok, so I was about to update the patch (didn't apply anymore) when I
also started looking at it's usage and realized that
NIX_CHROMIUM_PLUGIN_PATH_ (and other substrings) only appears in the
patch itself (i.e. it seemed like we don't need this patch anymore).
Turns out that we have this patch since 2014 (1b84fbf0ca) and it was
only ever used for NIX_CHROMIUM_PLUGIN_PATH_WIDEVINE (and from the log
it isn't clear if/when or how well that worked). But in 2019 that last
usage got removed (545d58a1ef) so we should be able to safely drop this
patch now :) \o/
(I just wanted to note that as it seemed somewhat of a funny story :D
But there is of course nothing wrong with it.)

After making `ffmpeg` point to the latest `ffmpeg_4`, all packages that
used `ffmpeg` without requiring a specific version now use ffmpeg_3
explicitly so they shouldn't change.
This provides the browser flag #enable-webrtc-pipewire-capturer, which
adds support for screensharing on Wayland via xdg-desktop-portal.
The browser flag is disabled by default until a user enables it. At
least one other major distribution (Arch) enables this compile time
option, and so I believe it should be safe to enable by default.
This is also needed to support xdg-desktop-portal-wlr which was added in
https://github.com/NixOS/nixpkgs/pull/83485.
The configuration phase was failing due to:
```
configuring

This can e.g. save around 150k lines of unnecessary log messages which

This makes it possible to use chromium headless with WebGL
(e.g. for webdriver tests) without having to rebuild from source.
The upstram default is to enable, thus simply removing our disabling switch.
Also fixes#41918.
This reverts commit 02ca096a85.
The clang-format binary is now included in the release tarball [0] and
we don't need to add it anymore. This fixes the following build error:
ln: failed to create symbolic link 'buildtools/linux64/clang-format': File exists
However, the build still fails a bit later in the configure phase.

The webrtc code suffered from a race condition when used
with Pulseaudio. This lead to audio input breaking every
couple of minutes during a webrtc session.
The fix from 1d961a4c6d was unfortunately incomplete. This commit fixes
the second error [0] that occurs later during the build (the Python
script third_party/blink/renderer/bindings/scripts/generate_bindings.py
requires buildtools/linux64/clang-format).

The skia patch no longer applies, and is no longer necessary.
The current version of chromium doesn't build with gcc. This has been
fixed upstream[1] and could be backported, but switching aarch64 to
clang/llvm and making the build the same on all platforms is simpler.
