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. PR: 166861 Reviewed by: emaste, ngie, pfg Approved by: emaste (mentor) MFC after: never Differential Revision: https://reviews.freebsd.org/D10315 |
