@nrpt-m mentioned that with upstream adding Rust in chromium 117, the tarball is ~3 GB.
Even before this, chromium-116.0.5845.187.tar.xz is 1.5 GB and 13 GB unpacked.
It seemed hard to believe that all of that data would be required to build chromium.
Using ncdu, the top level directories that are > 100 MiB are:

    9.7 GiB [##########] /third_party                                                                                                                                                         
  822.8 MiB [          ] /chrome

  104.3 MiB [          ] /ui
  101.0 MiB [          ] /ash

and the largest third-party componets are:

    1.6 GiB [##########] /llvm  
    1.5 GiB [######### ] /angle
    1.0 GiB [######    ] /swiftshader

  454.5 MiB [##        ] /devtools-frontend
  373.9 MiB [##        ] /catapult

Is it possible to use llvm and rust from YP/OE and does anyone think that it would be a good idea to look at other large directories and remove them or split them into a seperate tarball if not needed. Does anyone object to such a change assuming that it's not too painful to implement and maintain?

The tarball publishing process upstream already creates a tarball called "chromium-lite" which removes some directories, but this list is not very up-to-date and actively maintained.

As a first step one could see if this tarball is considerably smaller than the one we use and whether one can actually build Chromium from it.

As for using LLVM and Rust from YP/OE and the rest of the suggestion: do you mean creating a tarball of our own?

https://groups.google.com/a/chromium.org/g/chromium-packagers/c/oE60kVFFMyQ/m/xxF0DCnkAQAJ seems interesting:

Since distributions link against their own system libraries, and have
their own toolchains, we can exclude:

  • Debian sysroot(s)
  • Toolchain components (Rust, Clang, LLVM etc.)
  • third_party/instrumented_libs

I assume we don't want to actually use these third-party tarballs in our recipe, but maybe the -lite tarballs will get a little more attention again:

We are hoping that these changes will be accepted into the '-lite'
tarballs upstream, as these are no longer significantly smaller
than the standard Chromium tarball.

https://chromium-review.googlesource.com/c/chromium/tools/build/+/6072713 has landed, and this already affect the latest releases. e.g. https://storage.cloud.google.com/chromium-browser-official/chromium-131.0.6778.139-lite.tar.xz is only 1.9 GB. I'll give building with that a try. @rakuco if that works, should we switch to the lite tarballs?

Hm, it seems there are some licenses missing in the lite tarball:

The ios ones and the native_client_sdk one we can probably just remove from LIC_FILES_CHECKSUM (which reminds me that I wanted to do the same with the android stuff, oops). But e.g. libxml is definitely used on Linux, so its license should be in the tarball.

It seems this part of publish_tarball.py removes e.g. third_party/libxml/src, which includes the license file. I'll file an upstream issue.
