Heuristic with last-modified time in Qt has some problems. 1) Remove redundant expirationDate.isInvalid() check expirationDate.isInvalid is already checked. So I removed. 2) Add dateHeader.isInvalid() check The dateHeader is used in expiration calculation. I add invalid check for the dateHeader. *. The dateHeader is the origin server's Date 3) Change diff time calculation. The expirationDate is calculated with time diff. Previous calculation is // The lastModified is earlier than the currentDateTime. // The diff has negative value. int diff = currentDateTime.secsTo(lastModified); // The expirationDate is earlier than lastModified // , currentDateTime and dateHeader. expirationDate = lastModified.addSecs(diff / 10); *. currentDateTime: current time *. lastModified: last modified date in server It means that files are not cached with the heuristic. I changed diff calculation. int diff = lastModified.secsTo(dateHeader); freshness_lifetime = diff / 10; // RFC 2616 13.2.4 4) httpRequest.headerField setting If current_age is larger than 1 day, the cache MUST attach Warning 113. *. The current_age is value of age in header or elapsed time from dateHeader in Qt source code. Previous code does not check current_age is larger than 1 day correctly. // dt = 1970-01-01T00:00:00 + current_age dt.setTime_t(current_age); // currentDateTime is much bigger than 1970-01-01T00:00:00 if (dt.daysTo(currentDateTime) > 1) Task-number: QTBUG-40836 Change-Id: I4b00c3b287e6fafeea6b02681533fe75a198247e Reviewed-by: Jung Dong-Heon <dongheon.jung@lge.com> Reviewed-by: Peter Hartmann <phartmann@blackberry.com> |
