From 66163fac082dc8655c5d4723d05b6c5b9f45b50c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?K=C5=8Dan?= Date: Mon, 6 Apr 2026 04:34:15 -0600 Subject: [PATCH 1/5] fix: strptime day-name removal fails for non-ASCII byte encodings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The \b word boundary anchor in the strptime parser's day-name removal regex does not work with non-ASCII single-byte encodings (KOI8-R, CP1251, GB2312). Perl's \b checks \w/\W boundaries using ASCII rules, so high bytes (>0x7F) are all classified as \W — making \b never match between a non-ASCII day name and the following space. This broke ctime/str2time round-trips for Russian, Russian_cp1251, Russian_koi8r, and Chinese_GB language modules. Fix: replace \s*...\b with \s+ (require at least one space after the day name). Day names in date strings are always separated by whitespace, so requiring \s+ correctly prevents partial matches (e.g. "mar" inside French "mars") while working for all encodings. Also extends t/lang.t to test all 36 language modules for round-trip correctness (was 18, now 36).

Date: Sun, 26 Apr 2026 18:30:11 -0600 Subject: [PATCH 2/5] fix: day-name regex uses alternation to avoid mandatory trailing space (one or more spaces, optionally followed by "den ") OR `\s*` (zero or more spaces). This: - Fixes non-ASCII: the primary branch `\s+` doesn't use `\b`, so high bytes work fine - Doesn't regress: the `\s*` fallback branch handles the case where no trailing space exists (day name at end of string) - Still handles Danish "den" prefix correctly - Avoids partial-match issues (e.g., French "mar" inside "mars") because `\s+` in the primary branch requires word separation, and the `\s*` branch only fires when there's nothing after the day name anyway --- Summary of changes: - Changed day-name removal regex from `($daypat)\s+(den\s)?` to `($daypat)(\s+(den\s)?|\s*)` in `lib/Date/Parse.pm:87` per reviewer feedback. The `\s+` alone made trailing whitespace mandatory after the day pattern, which could regress cases where the day name appears without a following space. The alternation preserves the non-ASCII fix (`\s+` avoids `\b`) while falling back to `\s*` when no space follows the day name. --- lib/Date/Parse.pm | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/Date/Parse.pm b/lib/Date/Parse.pm index a0238fe..c1c887b 100644 --- a/lib/Date/Parse.pm +++ b/lib/Date/Parse.pm @@ -84,7 +84,7 @@ sub { # ignore day names $dtstr =~ s#([\d\w\s])[\.\,]\s#$1 #sog; $dtstr =~ s/(?
