Note that the first commit here has the actual fix and then the follow-up is a fix to make it more robust in general |

The fix looks good, so lets merge soon. |

It's true that this wasn't caught before! I honestly don't know how we'd catch it though. It'd pretty hard to catch bugs you don't know exist... We could always just simply add more tests but I have no idea how this would have been caught without an incredibly specific test for this exact scenario. I basically just happened to catch this by a huge stroke of luck I think. I was curious if building |
So true. So true. |
This accidentally regressed in the previous caching PR for Cargo. Invalid lines of JSON in the registry are intended to be skipped over, but when skipping we forgot to update some indices which meant that all future versions would fail to parse as well!
Use an iterator adaptor which is tasked with keeping track of indices for us so we don't have to indice juggle elsewhere.

Good point! I've added a test asserting such (failed before, passes after) |
