This PR initially patched #1899 to fix any unrelated errors and then reverted the PR. Two fixes in this PR:

  1. Shortening the test name to avoid maximum path length limit on windows.
  2. Disable more proto targets on windows because building rust_prost_toolchain now fails with the hash introduced by the transition in Support -Cpanic=abort #1899. The hash makes the the path over the limit as mentioned in (1).

@daivinhtran daivinhtran force-pushed the fix-test-names branch 2 times, most recently from b1d5428 to ba11c6d Compare October 26, 2023 15:39

Could we instead tag specific targets as incompatible with windows? How many targets fail on windows?

Pretty much all proto targets fail on windows because rust_prost_toolchain fails building on windows after #1899 introduces a transition to make the filepath even longer with the config hash.

@UebelAndre could we move this forward and disable windows the path length issues are taken care of?

I’m not convinced we need to disable the unit tests but haven’t had time to figure out if transitioning for the panic PR is necessary.
