Merge #2937
2937: Parse cargo output a line at a time. r=kiljacken a=kiljacken We previously used serde's stream deserializer to read json blobs from the cargo output. It has an issue though: If the deserializer encounters invalid input, it gets stuck reporting the same error again and again because it is unable to foward over the input until it reaches a new valid object. Reading a line at a time and manually deserializing fixes this issue, because cargo makes sure to only outpu one json blob per line, so should we encounter invalid input, we can just skip a line and continue. The main reason this would happen is stray printf-debugging in procedural macros, so we still report that an error occured, but we handle it gracefully now. Fixes #2935 Co-authored-by: Emil Lauridsen <[email protected]>
