Shallow clone support #18
Comments
|
Good catch! I removed that line as it seemed to imply shallow cloning has its own portion of the protocol. However, it's only a different way to do fetches and those implementing the protocol, e.g. the Repository, will be able to support shallow clones. I made that more explicit in the README now, and am thus closing this ticket. |

Thanks for the clarification :) |

The new URL should trigger an overflow check but it only
happens when `url::Url::parse()` is called directly as our
code doesn't let it through anymore.
Here is the log from the fuzzer run as reported:

You don't plan to support shallow clones ?
