* libc: regex: partial revert of r368358Kyle Evans2020-12-053-2/+6
| | | | | | | | | | | | | | Part of the libregex functionality leaked into the tests it shares with the standard regex(3). Introduce a P flag to set the REG_POSIX cflag to indicate that libc regex should effectively do nothing while libregex should specifically run it in non-extended mode. This unbreaks the libc/regex test run. Reported by: Jenkins Notes: svn path=/head/; revision=368371
* libregex: implement \b and \B (word boundary, not word boundary)Kyle Evans2020-12-051-1/+1
| | | | | | | | | | This is the last of the needed GNU expressions before we can unleash bsdgrep by default. \b is effectively an agnostic equivalent of \< and \>, while \B will match every space that isn't making a transition from nonchar -> char or char -> nonchar.

* regex(3): Interpret many escaped ordinary characters as EESCAPEKyle Evans2020-07-292-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In IEEE 1003.1-2008 [1] and earlier revisions, BRE/ERE grammar allows for any character to be escaped, but "ORD_CHAR preceded by an unescaped <backslash> character [gives undefined results]". Historically, we've interpreted an escaped ordinary character as the ordinary character itself. This becomes problematic when some extensions give special meanings to an otherwise ordinary character (e.g. GNU's \b, \s, \w), meaning we may have two different valid interpretations of the same sequence. To make this easier to deal with and given that the standard calls this undefined, we should throw an error (EESCAPE) if we run into this scenario to ease transition into a state where some escaped ordinaries are blessed with a special meaning -- it will either error out or have extended behavior, rather than have two entirely different versions of undefined behavior that leave the consumer of regex(3) guessing as to what behavior will be used or leaving them with false impressions. This change bumps the symbol version of regcomp to FBSD_1.6 and provides the old escape semantics for legacy applications, just in case one has an older application that would immediately turn into a pumpkin because of an extraneous escape that's embedded or otherwise critical to its operation. This is the final piece needed before enhancing libregex with GNU extensions and flipping the switch on bsdgrep.

* regex(3): Handle invalid {} constructs consistently and adjust testsKyle Evans2017-08-082-6/+30
| | | | | | | | | | | | | | | | | | | | | | | | | Currently, regex(3) exhibits the following wrong behavior as demonstrated with sed: - echo "a{1,2,3}b" | sed -r "s/{/_/" (1) - echo "a{1,2,3}b" | sed "s/\}/_/" (2) - echo "a{1,2,3}b" | sed -r "s/{}/_/" (3) Cases (1) and (3) should throw errors but they actually succeed, and (2) throws an error when it should match the literal '}'. The correct behavior was decided by comparing to the behavior with the equivalent BRE (1)(3) or ERE (2) and consulting POSIX, along with some reasonable evaluation. Tests were also adjusted/added accordingly.
