Print mistmatched weekdays as strings if they're valid. Fold long test name lines if needed. I renamed the buffers used to compare times so that the diagnostics are more useful. Spaces instead of dashes in time strings. ---- Test the transition points between all the currently listed Japanese era name changes. This includes testing the transition between the first year date and the second year date. This test will help test the upcoming Japanese era name change. Also fixes a fencepost error where the era name isn't properly parsed by strptime in the last (partial) year of the era. Example: if an era change happens in Feb 1990, and again in Aug 1995, that's 5.5 years long, but the 0.5 year wasn't accounted for. 2019-03-29 DJ Delorie [BZ #24394] * time/strptime_l.c (%Ey): Fix fencepost error. * time/tst-strftime3.c: New. * time/Makefile (tests): Add tst-strftime3. diff --git a/time/Makefile b/time/Makefile index 5c6304ece1..2ca206309d 100644 --- a/time/Makefile +++ b/time/Makefile @@ -43,7 +43,7 @@ tests := test_time clocktest tst-posixtz tst-strptime tst_wcsftime \ tst-getdate tst-mktime tst-mktime2 tst-ftime_l tst-strftime \ tst-mktime3 tst-strptime2 bug-asctime bug-asctime_r bug-mktime1 \ tst-strptime3 bug-getdate1 tst-strptime-whitespace tst-ftime \ - tst-tzname tst-y2039 bug-mktime4 tst-strftime2 + tst-tzname tst-y2039 bug-mktime4 tst-strftime2 tst-strftime3 include ../Rules diff --git a/time/strptime_l.c b/time/strptime_l.c index e19b9a15dd..7436a168b7 100644 --- a/time/strptime_l.c +++ b/time/strptime_l.c @@ -907,10 +907,15 @@ __strptime_internal (const char *rp, const char *fmt, struct tm *tmp, { int delta = ((tm->tm_year - era->offset) * era->absolute_direction); + /* The difference between two sets of years + does not include the final year itself, + therefore add 1 to the difference to + account for that final year. */ match = (delta >= 0 && delta < (((int64_t) era->stop_date[0] - (int64_t) era->start_date[0]) - * era->absolute_direction)); + * era->absolute_direction + + 1)); } if (! match) return NULL; @@ -928,10 +933,12 @@ __strptime_internal (const char *rp, const char *fmt, struct tm *tmp, { int delta = ((tm->tm_year - era->offset) * era->absolute_direction); + /* See comment above about year difference + 1. */ if (delta >= 0 && delta < (((int64_t) era->stop_date[0] - (int64_t) era->start_date[0]) - * era->absolute_direction)) + * era->absolute_direction + + 1)) { s.decided = loc; break; diff --git a/time/tst-strftime3.c b/time/tst-strftime3.c new file mode 100644 index 0000000000..274b9c3a65 --- /dev/null +++ b/time/tst-strftime3.c @@ -0,0 +1,451 @@ +/* Data-driven tests for strftime/strptime. + Copyright (C) 2019 Free Software Foundation, Inc.
