| * log: do not segfault on gmtime errorsJeff King2014-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | Many code paths assume that show_date and show_ident_date cannot return NULL. For the most part, we handle missing or corrupt timestamps by showing the epoch time t=0. However, we might still return NULL if gmtime rejects the time_t we feed it, resulting in a segfault. Let's catch this case and just format t=0. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * date: check date overflow against time_tJeff King2014-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we check whether a timestamp has overflowed, we check only against ULONG_MAX, meaning that strtoul has overflowed. However, we also feed these timestamps to system functions like gmtime, which expect a time_t. On many systems, time_t is actually smaller than "unsigned long" (e.g., because it is signed), and we would overflow when using these functions. We don't know the actual size or signedness of time_t, but we can easily check for truncation with a simple assignment.

When the user tells us to expire "all" (or set the expiration time to "now"), the user wants to remove all the reflog entries (no reflog entry should record future time). Just set it to ULONG_MAX and to let everything that is older that timestamp expire. While at it, allow "now" to be treated the same way for callers that parse expiry date timestamp with this function. Also use an error reporting version of approxidate() to report misspelled date. When the user says e.g. "--expire=mnoday" to delete entries two days or older on Wednesday, we wouldn't want the "unknown, default to now" logic to kick in.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only place that the issue this series addresses was observed where we read "cat-file commit" output and put it in GIT_AUTHOR_DATE in order to replay a commit with an ancient timestamp. With the previous patch alone, "git commit --date='20100917 +0900'" can be misinterpreted to mean an ancient timestamp, not September in year 2010. Guard this codepath by requring an extra '@' in front of the raw git timestamp on the parsing side. This of course needs to be compensated by updating get_author_ident_from_commit and the code for "git commit --amend" to prepend '@' to the string read from the existing commit in the GIT_AUTHOR_DATE environment variable.

| * | parse_date(): allow ancient git-timestampJunio C Hamano2012-02-03

This is to prevent a string like "20100917" from getting interpreted as seconds since epoch (we want to treat it as September 17, 2010 instead) while doing so. The same codepath is used to read back the timestamp that we have already recorded in the headers of commit and tag objects; because of this, such a commit with timestamp "0 +0000" cannot be rebased or amended very easily. Teach parse_date() codepath to special case a string of the form "<digits> +<4-digits>" to work this issue around, but require that there is no other cruft around the string when parsing a timestamp of this format for safety. Note that this has a slight backward incompatibility implications. If somebody writes "git commit --date='20100917 +0900'" and wants it to mean a timestamp in September 2010 in Japan, this change will break such a use case.

At the point where we calculate Y and M, we have the time delta specified as a number of days. We calculate these integers as: Y = days / 365 M = (days % 365 + 15) / 30 This rounds days in the latter half of a month up to the nearest month, so that day 16 is "1 month" (or day 381 is "1 year, 1 month"). We don't round the year at all, though, meaning we can end up with "1 year, 12 months", which is silly; it should just be "2 years". Implement this differently with months of size onemonth = 365/12 so that totalmonths = (long)( (days + onemonth/2)/onemonth ) years = totalmonths / 12 months = totalmonths % 12 In order to do this without floats, we write the first formula as totalmonths = (days*12*2 + 365) / (365*2) Tests and inspiration by Jeff King.

* | Export parse_date_basic() to convert a date string to timestampJonathan Nieder2010-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | approxidate() is not appropriate for reading machine-written dates because it guesses instead of erroring out on malformed dates. parse_date() is less convenient since it returns its output as a string. So export the underlying function that writes a timestamp. While at it, change the return value to match the usual convention: return 0 for success and -1 for failure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When no timezone is specified, we deduce the offset by subtracting the result of mktime from our calculated timestamp. However, our timestamp is stored as an unsigned integer, meaning we perform the subtraction as unsigned. For a negative offset, this means we wrap to a very high number, and our numeric timezone is in the millions of hours. You can see this bug by doing: $ TZ=EST \ GIT_AUTHOR_DATE='2010-06-01 10:00' \ git commit -a -m foo $ git cat-file -p HEAD | grep author author Jeff King <peff@peff.net> 1275404416 +119304128 Instead, we should perform this subtraction as a time_t, the same type that mktime returns.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For a long time, the time based reflog syntax (e.g. master@{yesterday}) didn't complain when the "human readable" timestamp was misspelled, as the underlying mechanism tried to be as lenient as possible. The funny thing was that parsing of "@{now}" even relied on the fact that anything not recognized by the machinery returned the current timestamp. Introduce approxidate_careful() that takes an optional pointer to an integer, that gets assigned 1 when the input does not make sense as a timestamp. As I am too lazy to fix all the callers that use approxidate(), most of the callers do not take advantage of the error checking, but convert the code to parse reflog to use it as a demonstration.

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.

* | Improve on 'approxidate'Linus Torvalds2009-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* | date/time: do not get confused by fractional secondsLinus Torvalds2008-08-17

Since we do not record anything finer grained than seconds, we could just drop fractional part, but there is a twist. We have taught people that not just spaces but dot can be used as word separators when spelling things like: $ git log --since 2.days $ git show @{12:34:56.7.days.ago} and we shouldn't mistake "7" in the latter example as a fraction and discard it. The rules are: - valid days of month/mday are always single or double digits. - valid years are either two or four digits No, we don't support the year 600 _anyway_, since our encoding is based on the UNIX epoch, and the day we worry about the year 10,000 is far away and we can raise the limit to five digits when we get closer. - Other numbers (eg "600 days ago") can have any number of digits, but they cannot start with a zero. Again, the only exception is for two-digit numbers, since that is fairly common for dates ("Dec 01" is not unheard of) So that means that any milli- or micro-second would be thrown out just because the number of digits shows that it cannot be an interesting date. A milli- or micro-second can obviously be a perfectly fine number according to the rules above, as long as it doesn't start with a '0'. So if we have 12:34:56.123 then that '123' gets parsed as a number, and we remember it. But because it's bigger than 31, we'll never use it as such _unless_ there is something after it to trigger that use. So you can say "12:34:56.123.days.ago", and because of the "days", that 123 will actually be meaninful now.

* | War on whitespaceJunio C Hamano2007-06-07
| | | | | | | | | | | | | | | | | | This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time. There are a few files that need to have trailing whitespaces (most notably, test vectors). The results still passes the test, and build result in Documentation/ area is unchanged.

* | Accept dates before 2000/01/01 when specified as seconds since the epochJohannes Sixt2007-06-06
| | | | | | | | | | | | | | | | | | | | | | | | Tests with git-filter-branch on a repository that was converted from CVS and that has commits reaching back to 1999 revealed that it is necessary to parse dates before 2000/01/01 when they are specified as seconds since 1970/01/01. There is now still a limit, 100000000, which is 1973/03/03 09:46:40 UTC, in order to allow that dates are represented as 8 digits.

* | Add --date={local,relative,default}Junio C Hamano2007-04-25
| | | | | | | | | | | | | | | | | | | | | | This adds --date={local,relative,default} option to log family of commands, to allow displaying timestamps in user's local timezone, relative time, or the default format. Existing --relative-date option is a synonym of --date=relative; we could probably deprecate it in the long run. Signed-off-by: Junio C Hamano <junkio@cox.net>
* | show_date(): rename the "relative" parameter to "mode"Johannes Schindelin2007-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now, show_date() can print three different kinds of dates: normal, relative and short (%Y-%m-%s) dates. To achieve this, the "int relative" was changed to "enum date_mode mode", which has three states: DATE_NORMAL, DATE_RELATIVE and DATE_SHORT. Since existing users of show_date() only call it with relative_date being either 0 or 1, and DATE_NORMAL and DATE_RELATIVE having these values, no behaviour is changed.

* | show_date(): fix relative datesJohannes Schindelin2007-01-20
| | | | | | | | | | | | | | | | We pass a timestamp (i.e. number of seconds elapsed since Jan 1 1970, 00:00:00 GMT) to the function. So there is no need to "fix" the timestamp according to the timezone. Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de>
* | simplify inclusion of system header files.Junio C Hamano2006-12-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a mechanical clean-up of the way *.c files include system header files. (1) sources under compat/, platform sha-1 implementations, and xdelta code are exempt from the following rules; (2) the first #include must be "git-compat-util.h" or one of our own header file that includes it first (e.g. config.h, builtin.h, pkt-line.h); (3) system headers that are included in "git-compat-util.h" need not be included in individual C source files. (4) "git-compat-util.h" does not have to include subsystem specific header files (e.g. expat.h). Signed-off-by: Junio C Hamano <junkio@cox.net>
* | Fix approxidate() to understand 12:34 AM/PM are 00:34 and 12:34Linus Torvalds2006-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It just simplifies the whole thing to say "hour = (hour % 12) + X" where X is 12 for PM and 0 for AM. It also fixes the "exact date" parsing, which didn't parse AM at all, and as such would do the same "12:30 AM" means "12:30 24-hour-format" bug. Of course, I hope that no exact dates use AM/PM anyway, but since we support the PM format, let's just get it right.

* | Clean up approxidate() in preparation for fixesLinus Torvalds2006-09-28
| | | | | | | | | | | | | | | | | | | | Our approxidate cannot handle simple times like "5 PM yesterday", and to fix that, we will need to add some logic for number handling. This just splits that out into a function of its own (the same way the _real_ date parsing works). Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
