Jeff King 9b591b9403 strbuf_addftime(): handle "%s" manually The strftime() function has a non-standard "%s" extension, which prints the number of seconds since the epoch. But the "struct tm" we get has already been adjusted for a particular time zone; going back to an epoch time requires knowing that zone offset. Since strftime() doesn't take such an argument, round-tripping to a "struct tm" and back to the "%s" format may produce the wrong value (off by tz_offset seconds). Since we're already passing in the zone offset courtesy of `c3fbf81a85` (strbuf: let strbuf_addftime handle %z and %Z itself, 2017-06-15), we can use that same value to adjust our epoch seconds accordingly. Note that the description above makes it sound like strftime()'s "%s" is useless (and really, the issue is shared by mktime(), which is what strftime() would use under the hood). But it gets the two cases for which it's designed correct: - the result of gmtime() will have a zero offset, so no adjustment is necessary - the result of localtime() will be offset by the local zone offset, and mktime() and strftime() are defined to assume this offset when converting back (there's actually some magic here; some implementations record this in the "struct tm", but we can't portably access or manipulate it. But they somehow "know" whether a "struct tm" is from gmtime() or localtime()). This latter point means that "format-local:%s" actually works correctly already, because in that case we rely on the system routines due to `6eced3ec5e` (date: use localtime() for "-local" time formats, 2017-06-15). Our problem comes when trying to show times in the author's zone, as the system routines provide no mechanism for converting in non-local zones. So in those cases we have a "struct tm" that came from gmtime(), but has been manipulated according to our offset. The tests cover the broken round-trip by formatting "%s" for a time in a non-system timezone. We use the made-up "+1234" here, which has two advantages. One, we know it won't ever be the real system zone (and so we're actually testing a case that would break). And two, since it has a minute component, we're testing the full decoding of the +HHMM zone into a number of seconds. Likewise, we test the "-1234" variant to make sure there aren't any sign mistakes. There's one final test, which covers "format-local:%s". As noted, this already passes, but it's important to check that we didn't regress this case. In particular, the caller in show_date() is relying on localtime() to have done the zone adjustment, independent of any tz_offset we compute ourselves. These should match up, since our local_tzoffset() is likewise built around localtime(). But it would be easy for a caller to forget to pass in a correct tz_offset to strbuf_addftime(). Fortunately show_date() does this correctly (it has to because of the existing handling of %z), and the test continues to pass. So this one is just future-proofing against a change in our assumptions. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>		2021-11-04 12:38:09 -07:00

Git - fast, scalable, distributed revision control system

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.

Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.

Please read the file INSTALL for installation instructions.

Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.

See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.

CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).

The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.

Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.

The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.

The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):

random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
"global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
"goddamn idiotic truckload of sh*t": when it breaks
