This is a minor matter, which I considered deciding myself or bringing up on irc, but in the end thought it best to get wider feedback. The test file locale.t is now improved with more tests that look for improper locale implementations. For example, it verifies that \s and \w are disjoint, that [:lower:] is a subset of [:alpha:], and other checks that a POSIX-conforming locale definition should pass. The .t has long had reasonable debugging output (when enabled) for helping find out what's wrong with locales that fail. Some years ago, it was changed so that if a platform has only up to 5% of its locales fail, it doesn't fail the .t, but marks those ones failing as TODO. This has the advantage of not failing the build over a few defective locales on the platform, but the disadvantage that someone doesn't know that they have defective locales unless more than 5% are bad, unless they run the test manually. I have just changed locale.t so it uses an environment variable to switch into debug mode, and to actually fail if it encounters any bad locales, with improved diagnostics as to what is wrong. The question is should we publicize this, and if so, how? It would only work for people who have the perl source tree or somehow could get t/test.pl working. My thought would be to add a section to perllocale.pod detailing this possibility and how to do it. Any feedback?Thread Next
