The comment may be a little misleading as it sounds like this is a guaranteed fix for the problem. It actually relies on the underlying writer being line buffered as well as the message itself not containing any newlines. These assumptions are true 95% of the time, but I think they should be reflected in the comment. r=me with the comment adjustment. |
When printing colored diagnostics, we need to reset the terminal before emitting the newline, not after. Otherwise it gets line-buffered and the color won't reset until the next line is printed or the compiler exits. Normally this isn't a problem, but when running rustc in parallel with other processes (e.g. `make -j4`) this can cause the color to leak to other lines.
