From 45c956b35731fcbda4cf29fcd1658d9418bec2d1 Mon Sep 17 00:00:00 2001 From: Ryuichi Kokubo Date: Thu, 26 Feb 2015 01:04:41 +0900 Subject: git-svn: fix localtime=true on non-glibc environments git svn uses POSIX::strftime('%s', $sec, $min, ...) to make unix epoch time. But lowercase %s formatting character is a GNU extention. This causes problem in git svn fetch --localtime on non-glibc systems, such as msys or cygwin. Using Time::Local::timelocal($sec, $min, ...) fixes it. Signed-off-by: Ryuichi Kokubo Signed-off-by: Eric Wong Notes: lowercase %s format character in strftime is a GNU extension and not widely supported. POSIX::strftime affected by underlying crt's strftime because POSIX::strftime just calls crt's one. Time::Local is good function to replace POSIX::strftime because it's a perl core module function. Document about Time::Local. http://perldoc.perl.org/Time/Local.html These are specifications of strftime. The GNU C Library Reference Manual. http://www.gnu.org/software/libc/manual/html_node/Formatting-Calendar-Time.html perl POSIX module's strftime document. It does not have '%s'. http://perldoc.perl.org/POSIX.html strftime document of Microsort Windows C Run-Time library. https://msdn.microsoft.com/en-us/library/fe06s4ak.aspx The Open Group's old specification does not have '%s' too. http://pubs.opengroup.org/onlinepubs/007908799/xsh/strftime.html On my environment, following problems happened. - msys : git svn fetch does not progress at all with perl.exe consuming CPU. - cygwin : git svn fetch progresses but time stamp information is dropped. Every commits have unix epoch timestamp. I would like to thank git developer and contibutors. git helps me so much everyday. Thank you.
