From grep abseil srcpkg/*/template, I was able to learn following packages depend on abseil-cpp:

• webrtc-audio-processing - Compiles fine, no changes
  • webrtc-audio-processing-2 - Compiles fine, no changes
• grpc - Update to v1.81.1
  • Tested with:
    • x86_64-glibc
  • Subpackages:
    • libgrpc
    • python3-grpcio
• protobuf - Update to v35.1
  • Tested with:
    • x86_64-glibc
    • x86_64-musl
  • Subpackages:
    • libprotobuf(-devel)
    • libprotobuf-lite(-devel)
    • libprotoc(-devel)
• mozc - Skipped since it fetches abseil separately by itself.
  • mozc-base
  • ibus-mozc
  • fcitx5-mozc
• marble - Compiles fine, no changes
  • marble5
• libreoffice-*
• justbuild
• gfan - Compiles fine, no changes
• android-tools - See abseil-cpp: update to 20260526.0. #61200 (comment)
• tg_owt - Compiles fine, no changes
• re2 - Compiles fine, no changes BUT! re2 needs to be recompiled!

Due to the sheer number of packages, I will try to only compile for x86_64-glibc and x86_64-musl locally. I'll let CI test for 32-bit and arm.

I had to update protobuf to 35.1. This does mean a looottt more packages will need to be tested. I might break this into two prs updating protobuf after abseil.

[dora-meowmeow]

A patch had to be made for android-tools as it tries to concatenate a std::string with an std::string_view. Aside from that it compiles fine.

[dora-meowmeow]

had to bump re2 just so it recompiles for the CI tests. Should I revert it once it is ready to be merged?

[dora-meowmeow]

I removed libreoffice and justbuild from the test. I am not sure at this point how to test it. I just hope the PR doesn't break it. I'll check if the versions of the software support latest abseil.

Its so weird, I don't understand why some CIs take almost 90 minutes while others take 20? Additionally they did not fail in compiling they failed in repository state???
