#!./perl -wT use strict; use warnings; use Config; # This tests plain 'use locale' and adorned 'use locale ":not_characters"' # Because these pragmas are compile time, and I (khw) am trying to test # without using 'eval' as much as possible, which might cloud the issue, the # crucial parts of the code are duplicated in a block for each pragma. # Unfortunately, many systems have defective locale definitions. This test # file looks for both perl bugs and bugs in the system's locale definitions. # It can be difficult to tease apart which is which. For the latter, there # are tests that are based on the POSIX standard. A character isn't supposed # to be both a space and graphic, for example. Another example is if a # character is the uppercase of another, that other should be the lowercase of # the first. Including tests for these allows you to test for defective # locales, as described in perllocale. The way this file distinguishes # between defective locales, and perl bugs is to see what percentage of # locales fail a given test. If it's a lot, then it's more likely to be a # perl bug; only a few, those particular locales are likely defective. In # that case the failing tests are marked TODO. (They should be reported to # the vendor, however; but it's not perl's problem.) In some cases, this # script has caused tickets to be filed against perl which turn out to be the # platform's bug, but a higher percentage of locales are failing than the # built-in cut-off point. For those platforms, code has been added to # increase the cut-off, so those platforms don't trigger failing test reports. # Ideally, the platforms would get fixed and that code would be changed to # only kick-in when run on versions that are earlier than the fixed one.
