split(1): auto-extend suffix length if required

2023-09-14T14:59:52Z

If the input cannot be split into the number of files resulting from the default suffix length, automatically extend the suffix length rather than bailing out with 'too many files'. Suffixes are extended such that the resulting files continue to sort lexically and "cat *" would reproduce the input. For example, splitting a 1M lines file into (default) 1000 lines per file would yield files named 'xaa', 'xab', ..., 'xyy', 'xyz', 'xzaaa', 'xzaab', ..., 'xzanl'. If '-a' is specified, the suffix length is not auto-extended. This behavior matches GNU sort(1) since around version 8.16.

split: switch to getline() for line/pattern matching

2022-11-11T18:08:46Z

Get rid of split's home-grown logic for growing the buffer; arbitrarily breaking at LONG_MAX bytes instead of 65536 bytes gives us much more wiggle room. Additionally, we'll actually fail out entirely if we can't fit a line, which makes noticing this class of problem much easier. Reviewed by: bapt, emaste, pauamma Sponsored by: Klara, Inc.

Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96
