2024-10-02libdiff: Implement diff coloring.Dag-Erling Smørgrav
This patch got accidentally left out when libdiff was imported. The rest of the code (command-line option etc.) was present, just not the part that actually prints ANSI color codes. Sponsored by: Klara, Inc. Reviewed by: kevans Differential Revision: https://reviews.freebsd.org/D46873
2024-05-20libdiff: Detect and recover from file truncation.Dag-Erling Smørgrav
If a memory-mapped file is truncated before we get to the end, the atomizer may catch SIGBUS. Detect that, reduce the input length to what we were actually able to read, and set a flag so the caller can take further action (e.g. warn the user and / or start over). Sponsored by: Klara, Inc.
