There are a variety of issues with using GTest sharding by default for users of `lit` using the Google Test formatter as mentioned in https://github.com/llvm/llvm-project/issues/56492 and https://github.com/llvm/llvm-project/issues/56491. Currently, there is no way for users to explicitly control the sharding behavior, even with the environment variables that GTest provides. This patch teaches the `googletest` formatter to actually respect `GTEST_TOTAL_SHARDS` and `GTEST_SHARD_INDEX` environment variables if they are set. In practice, we could go one step further and not do any of the post-processing of the JSON files if `GTEST_TOTAL_SHARDS` is `1` for example, but that it left as a follow-up if desired. There may be preferred alternative approaches to disabling sharding entirely through another mechanism, such as a lit config variable. Differential Revision: https://reviews.llvm.org/D133542 |
