Reported by @bmack in #31107 (comment)
This highlights a small inconsistency that exists for a long time (checked on 2.7 at least):
new Route('/en-en/{b}', ['b' => 'bbb'], ['b' => '.*'])
matches/en-en/
new Route('/en-en/{b}', ['b' => 'bbb'], ['b' => '.+'])
doesn't match it(while both match
/en-en
and/en-en/foo
)This PR ensures the former behavior is preserved, while #31167 redirects the later to
/en-en
.
