From 8326fe1f7e141f49a46a57acc6221651298b42c9 Mon Sep 17 00:00:00 2001 From: Elliott Hughes Date: Thu, 7 Feb 2019 19:03:30 -0800 Subject: date: some fixes. Add support for more input formats, primarily the ISO formats used by the AOSP build. I've improved/added to the tests a bit to cover these changes, and to explain the reasons for the various remaining test failures (none of which are regressions caused by this patch). --- tests/date.test | 49 ++++++++++++++++++++++++++++++++----------------- 1 file changed, 32 insertions(+), 17 deletions(-) (limited to 'tests') diff --git a/tests/date.test b/tests/date.test index 431b35ab..e0da9a44 100644 --- a/tests/date.test +++ b/tests/date.test @@ -4,25 +4,38 @@ #testing "name" "command" "result" "infile" "stdin" -# Test Unix date parsing. -testing "-d @0" "TZ=UTC date -d @0 2>&1" "Thu Jan 1 00:00:00 GMT 1970\n" "" "" -testing "-d @0x123" "TZ=UTC date -d @0x123 2>&1" "date: bad date '@0x123'\n" "" "" - -# Test basic date parsing. -# Note that toybox's -d format is not the same as coreutils'. -testing "-d 06021234" "TZ=UTC date -d 06021234 2>&1" "Sun Jun 2 12:34:00 UTC 1900\n" "" "" -testing "-d 060212341982" "TZ=UTC date -d 060212341982 2>&1" "Sun Jun 2 12:34:00 UTC 1982\n" "" "" -testing "-d 123" "TZ=UTC date -d 123 2>&1" "date: bad date '123'\n" "" "" -testing "-d 2018-10-04" "TZ=UTC date -d 2018-10-04 2>&1" "Thu Oct 4 00:00:00 UTC 2018\n" "" "" - -# Test parsing 2- and 4-digit years. -testing "-d 1110143115.30" "TZ=UTC date -d 1110143115.30 2>&1" "Sun Nov 10 14:31:30 UTC 1915\n" "" "" -testing "-d 111014312015.30" "TZ=UTC date -d 111014312015.30 2>&1" "Sun Nov 10 14:31:30 UTC 2015\n" "" "" - -# Accidentally given a Unix time, we should trivially reject that. -testing "Unix time missing @" "TZ=UTC date 1438053157 2>/dev/null || echo no" \ +# Use a consistent TZ for these tests, but not GMT/UTC because that makes mistakes harder to spot. +tz=Europe/London + +# Unix date parsing. +testing "-d @0" "TZ=$tz date -d @0 2>&1" "Thu Jan 1 01:00:00 BST 1970\n" "" "" +testing "-d @0x123 invalid" "TZ=$tz date -d @0x123 2>/dev/null || echo expected error" "expected error\n" "" "" + +# TODO: these are rejected by coreutils and interpreted differently by busybox. +# busybox thinks this should use the current year, not 1900. +testing "-d 06021234" "TZ=$tz date -d 06021234 2>&1" "Sun Jun 2 12:34:00 UTC 1900\n" "" "" +# busybox thinks this is the year 603 (ISO time 0602-12-34 19:82 with out of range fields normalized). +testing "-d 060212341982" "TZ=$tz date -d 060212341982 2>&1" "Sun Jun 2 12:34:00 UTC 1982\n" "" "" + +# POSIX format with 2- and 4-digit years. +# TODO: coreutils rejects POSIX format supplied to -d. +testing "-d 1110143115.30" "TZ=$tz date -d 1110143115.30 2>&1" "Sun Nov 10 14:31:30 UTC 1915\n" "" "" +testing "-d 111014312015.30" "TZ=$tz date -d 111014312015.30 2>&1" "Sun Nov 10 14:31:30 UTC 2015\n" "" "" + +# ISO date format. +testing "-d 1980-01-02" "TZ=$tz date -d 1980-01-02 2>&1" "Wed Jan 2 00:00:00 GMT 1980\n" "" "" +testing "-d 1980-01-02 12:34" "TZ=$tz date -d '1980-01-02 12:34' 2>&1" "Wed Jan 2 12:34:00 GMT 1980\n" "" "" +testing "-d 1980-01-02 12:34:56" "TZ=$tz date -d '1980-01-02 12:34:56' 2>&1" "Wed Jan 2 12:34:56 GMT 1980\n" "" "" + +# Reject Unix times without a leading @. +testing "Unix time missing @" "TZ=$tz date 1438053157 2>/dev/null || echo no" \ "no\n" "" "" +# Test just hour and minute (accepted by coreutils and busybox, presumably for setting the time). +this_year=$(date +%Y) +testing "-d 12:34" 'TZ=UTC date -d 12:34 | grep -q " 12:34:00 UTC $this_year" && echo OK' "OK\n" "" "" +testing "-d 12:34:56" 'TZ=UTC date -d 12:34:56 | grep -q " 12:34:56 UTC $this_year" && echo OK' "OK\n" "" "" + # Test the %N extension to srtftime(3) format strings. testing "%N" "touch -d 2012-01-23T12:34:56.123456789 f && date -r f +%Y%m%d-%H%M%S.%N" "20120123-123456.123456789\n" "" "" testing "%1N" "touch -d 2012-01-23T12:34:56.123456789 f && date -r f +%Y%m%d-%H%M%S.%1N" "20120123-123456.1\n" "" "" @@ -35,5 +48,7 @@ testing "just %" "touch -d 2012-01-23T12:34:56.123456789 f && date -r f +%" "%\n rm -f f # Test embedded TZ to take a date in one time zone and display it in another. +# TODO: not yet working correctly in toybox. +testing "TZ=" "TZ='America/Los_Angeles' date -d 'TZ=\"Europe/London\" 2018-01-04 08:00'" "Thu Jan 4 00:00:00 PST 2018\n" "" "" testing "TZ=" "TZ='America/Los_Angeles' date -d 'TZ=\"Europe/London\" 2018-10-04 08:00'" "Thu Oct 4 00:00:00 PDT 2018\n" "" "" testing "TZ= @" "TZ='America/Los_Angeles' date -d 'TZ=\"GMT\" @1533427200'" "Sat Aug 4 17:00:00 PDT 2018\n" "" "" -- cgit v1.2.3
