quoting from HTTP 1.1 bis Prior to 1995, there were three different formats commonly used by servers to communicate timestamps. For compatibility with old implementations, all three are defined here. The preferred format is a fixed-length and single-zone subset of the date and time specification used by the Internet Message Format [RFC5322]. HTTP-date = IMF-fixdate / obs-date An example of the preferred format is Sun, 06 Nov 1994 08:49:37 GMT ; IMF-fixdate Examples of the two obsolete formats are Sunday, 06-Nov-94 08:49:37 GMT ; obsolete RFC 850 format Sun Nov 6 08:49:37 1994 ; ANSI C's asctime() format A recipient that parses a timestamp value in an HTTP header field MUST accept all three formats. A sender MUST generate the IMF- fixdate format when sending an HTTP-date value in a header field. What http.server.BaseHTTPRequestHandler.date_time_string is currently doing >>> import time >>> timestamp = time.time() >>> weekdayname = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'] >>> monthname = [None,'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun','Jul', 'Aug', >>> 'Sep', 'Oct', 'Nov', 'Dec'] >>> year, month, day, hh, mm, ss, wd, y, z = time.gmtime(timestamp) >>> s = "%s, %02d %3s %4d %02d:%02d:%02d GMT" % (weekdayname[wd],day, >>> monthname[month], year,hh, mm, ss) >>> s 'Mon, 25 Feb 2013 19:26:34 GMT' what email.utils.formatdate is doing: >>> import email.utils >>> email.utils.formatdate(timeval=None,localtime=False, usegmt=True) 'Mon, 25 Feb 2013 19:40:04 GMT' >>> import time >>> ts = time.time() >>> email.utils.formatdate(timeval=ts,localtime=False, usegmt=True) 'Mon, 25 Feb 2013 19:51:50 GMT' I createad a patch s = email.utils.formatdate(timestamp, False, True) I didn't touch the log method which has a different format which is anyway not compatible with email.utils. ---------- keywords: +patch nosy: +karlcow Added file: http://bugs.python.org/file29240/server.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue747320> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
