Omit the -q option from xz, gzip, and bzip2. With xz this shouldn't matter. With gzip it's important because -q makes gzip replace SIGPIPE with exit status 2. With bzip2 it's important because with -q bzip2 is completely silent if input is corrupt while other decompressors still give an error message. Avoiding exit status 2 from gzip is important because bzip2 uses exit status 2 to indicate corrupt input. Before this commit xzgrep didn't recognize corrupt .bz2 files because xzgrep was treating exit status 2 as SIGPIPE for gzip compatibility. zstd still needs -q because otherwise it is noisy in normal operation. The code to detect real SIGPIPE didn't check if the exit status was due to a signal (>= 128) and so could ignore some other exit status too. |
