From 9029055207443c28ca65a705d1a1b96cce3995fd Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 22 Aug 2009 15:10:07 -0700 Subject: [PATCH 1/6] Improve on 'approxidate' This is not a new failure mode - approxidate has always been kind of random in the input it accepts, but some of the randomness is more irritating than others. For example: Jun 6, 5AM -> Mon Jun 22 05:00:00 2009 5AM Jun 6 -> Sat Jun 6 05:00:00 2009 Whaa? The reason for the above is that approxidate squirrells away the '6' from "Jun 6" to see if it's going to be a relative number, and then forgets about it when it sees a new number (the '5' in '5AM'). So the odd "June 22" date is because today is July 22nd, and if it doesn't have another day of the month, it will just pick todays mday - having ignored the '6' entirely due to getting all excited about seeing a new number (5). There are other oddnesses. This does not fix them all, but I think it makes for fewer _really_ perplexing cases. At least now we have Jun 6, 5AM -> Sat Jun 6 05:00:00 2009 5AM, Jun 6 -> Sat Jun 6 05:00:00 2009 which makes me happier. I can still point to cases that don't work as well, but those are separate issues.

For example, using a date string like 6AM, June 7, 2009 the strict date logic would be perfectly happy with the "June 7, 2009" part, and ignore the 6AM part that it didn't understand - resulting in the information getting dropped on the floor: 6AM, June 7, 2009 -> Sat Jun 6 00:00:00 2009 and the date being calculated as if it was midnight, and the '6AM' having confused the date routines into thinking about '6 June' rather than 'June 7' at 6AM (ie notice how the _day_ was wrong due to this, not just the time). So this makes the strict date routines a bit stricter, and requires that not just the date, but also the time, has actually been parsed. With that fix, and trivial extension of the approxidate routines, git now properly parses the date as 6AM, June 7, 2009 -> Sun Jun 7 06:00:00 2009 without dropping the fuzzy time ("6AM" or "noon" or any of the other non-strict time formats) on the floor.

However, it is not actually used by the test suite to do any sort of automatic of systematic tests. This patch refactors the interface to the program to try to make it more suitable for use by the test suite. There should be no fallouts to changing the interface since it is not actually installed and is not internally called by any other programs. The changes are: - add a "mode" parameter so the caller can specify which operation to test - add a mode to test relative date output from show_date - allow faking a fixed time via the TEST_DATE_NOW environment variable, which allows consistent automated testing - drop the use of ctime for showing dates in favor of our internal iso8601 printing routines. The ctime output is somewhat redundant (because of the day-of-week) which makes writing test cases more annoying.

This new script tries to exercise the basic features of show_date and approxidate. Most of the tests are just "this obvious thing works" to prevent future regressions, with a few exceptions: - We confirm the fix in 607a9e8 that relative year/month dates in the latter half of a year round correctly. - We confirm that the improvements in b5373e9 and 1bddb25 work. - A few tests are marked to expect failure, which are regressions recently introduced by the two commits above.

The problem is that the code marks the month and year with "-1" for "we don't know it yet", but the month and year code paths were not adjusted to fill in the current time before doing their calculations (whereas other units follow a different code path and are fine).
