  # Comment from @code-asher, the code-server maintainer
  # See https://github.com/NixOS/nixpkgs/pull/240001#discussion_r1244303617
  #
  # If the commit is missing it will break display languages (Japanese, Spanish,
  # etc). For some reason VS Code has a hard dependency on the commit being set
  # for that functionality.
  # The commit is also used in cache busting. Without the commit you could run
  # into issues where the browser is loading old versions of assets from the
  # cache.
  # Lastly, it can be helpful for the commit to be accurate in bug reports
  # especially when they are built outside of our CI as sometimes the version
  # numbers can be unreliable (since they are arbitrarily provided).
  #
  # To compute the commit when upgrading this derivation, do:
  # `$ git rev-parse <git-rev>` where <git-rev> is the git revision of the `src`
  # Example: `$ git rev-parse v4.16.1`
