Updating dependencies

Bazel llvm_toolchain

Donner uses a modified version of llvm_toolchain to prototype libclang-based tools (such as the archived hdoc experiment, in the hdoc-archive branch).

To update to a new version, modify MODULE.bazel:

git_override(
    module_name = "toolchains_llvm",
    remote = "https://github.com/jwmcglynn/toolchains_llvm",
    commit = "ac1836bde88f7a55e3d6c0161844d98ae9bf861e",
)

To locally test changes, assuming repro is cloned locally next to the donner directory:

- git_override(
-     module_name = "toolchains_llvm",
-     remote = "https://github.com/jwmcglynn/toolchains_llvm",
-     commit = "ac1836bde88f7a55e3d6c0161844d98ae9bf861e",
- )
+ local_path_override(
+     module_name = "toolchains_llvm",
+     path = "../toolchains_llvm",
+ )

Skia version

There's a fork of the skia library at https://github.com/jwmcglynn/skia, which contains fixes for build errors compared to the upstream version.

To pull a new version, in a local clone of the https://github.com/jwmcglynn/skia repo, run:

git fetch upstream
git checkout -b new_upstream upstream/main

To test it against a local Donner MODULE.bazel, modify the skia repository to point to your local skia repo:

- git_repository(
-     name = "skia",
-     commit = "aaf2f8dd2bba1260395c90635d83df271e753fbd",
-     remote = "https://github.com/jwmcglynn/skia",
- )
+ local_repository(
+     name = "skia",
+     path = "/path/to/skia",
+     # For example:
+     # path = "../skia",
+ )

Then build Donner and verify if it works.

bazel build //...
bazel test //...
