Problem

When updating the index, only index.crates.io-6f17d22bba15001f index is updated, but not github.com-1ecc6299db9ec823.

Steps

1. Run any command that should update the index (e.g. cargo update --dry-run )
2. Check that index.crates.io-6f17d22bba15001f index is updated
3. Check that github.com-1ecc6299db9ec823 index isn't updated

This is expected and exactly the purpose sparse registry index was designed for — skipping the update of Git-based registry index. Cargo updates only the registry index for the default protocol of your choice. By default it is the sparse protocol since 1.68.

Is there any issue you encountered with this behavior?

@weihanglo thank you for your answer
As discussed in #3377, this index is used in various tools (intellij-rust in my case) to gather information about the crates. I've noticed that the github index stopped updating, and it was causing problems for us, for example intellij-rust/intellij-rust#10644
I'll try setting the github index as default one, thank you!

I am not sure what it wasn't reported earlier, since sparse registry was in beta for a long while, and got stabilized in March this year. For intellij-rust perhaps some bugs were introduced in recent.

Anyway, here is a workaround to forced update the Git-based registry index: CARGO_REGISTRIES_CRATES_IO_PROTOCOL=git cargo fetch

Closing in favor of other prior issues:

• Please provide a subcommand to refresh the crates.io index #3377
• Sparse registry indexes should be viewable atomically #10928
• Command for introspecting on the index #11034

Thank you for the report!
