I'm sure that "Binary files differ" was reported. The reason is that your pdfresetdate script is not idempotent. Look: $ pdfresetdate < x.pdf > y.pdf $ pdfresetdate < y.pdf > z.pdf $ md5sum x.pdf y.pdf z.pdf c46a7097574a035e89d1a46d93c83528 x.pdf 8e6d942b4cc7d8a4dfe6898867573617 y.pdf e6333bc0f8ab9781d3e1d811a392d516 z.pdf A file that was already cleaned by the clean filter must not be modified, i.e., the y.pdf and z.pdf should be identical. But they are not. Fix your clean filter. -- Hannes -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
