* split: Add missing test cases.Dag-Erling Smørgrav2023-09-071-22/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds test cases for c4f7198f47c1 and ac17fc816e67. MFC after: 1 week Sponsored by: Klara, Inc.

The “undocumented kludge” which unfortunately can't be dropped for backward compatibility reasons was prone to segfaulting and would improperly allow a new linecount when one was already set. Fix these issues and add regression tests. MFC after: 1 week Sponsored by: Klara, Inc.

* split(1): add '-c' to continue creating filesJan Schaumann2023-05-301-8/+20
| | | | | | | | | | | | | | | | | | | | | Currently, split(1) will clobber any existing output files: $ split file; ls xaa xab xac xad $ split second-file; ls xaa xab xac xad xae xaf This patch adds a flag "-c" (mnemonic "create, don't overwrite" or "continue where you left off"): $ split file; ls xaa xab xac xad $ split -c second-file; ls xaa xab xac xad xae xaf xag xah xai xaj Reviewed by: christos Approved by: kevans Different Revision: https://reviews.freebsd.org/D38553
* split(1): auto-extend suffix length if requiredJan Schaumann2023-05-301-0/+31
| | | | | | | | | | | | | | | | | | | 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: reset errno prior to getline()Math Ieu2022-10-271-1/+1
| | | | | | | | | Something else may have set errno, breaking the post-getline() logic that tries to detect the getline() error. This was initially noted in a jail on a system that has HPET, in a jail that does not expose /dev/hpet0 -- we see an earlier error in libc's vdso bits. Fixes: 5c053aa3c5e90 ("split: switch to getline() [...]")
* split: switch to getline() for line/pattern matchingKyle Evans2022-10-251-13/+12
| | | | | | | | | | | 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.

* Convert pnmatch to single element array in regexec callsAlexander Kabaev2019-10-021-4/+4
| | | | | | | | | | | | | | The regexec function is declared as taking an array of regmatch_t elements, and passing in the pointer to singleton element, while correct, triggers a Coverity warning. Convert the singleton into an array of one to silence the warning. Reported by: Coverity Coverity CID: 1009732, 1009733 MFC after: 2 weeks Notes: svn path=/head/; revision=352953
* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-1/+3
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025
* Renumber copyright clause 4Warner Losh2017-02-281-1/+1

My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.
