QDateTime will attempt to convert unknown types of date to UTC time, which isn't exactly a fast process. As we don't care about local timezones in the process of sorting (as this is purely for ordering, not display to the end user), we can force the dates to use UTC time, avoiding the unnecessary local timezone lookup. This also adds a benchmark covering this case. Benchmark results, Qt 5: - before: 11, 489ms - after: 273ms Qt 4.8: - before: 20, 848ms - after: 278ms Change-Id: I87fa6260e820b5b172d3306ff395dafe767c33ff Reported-by: Thomas Perl <m@thp.io> Reviewed-by: Alberto Mardegan <mardy@users.sourceforge.net> Reviewed-by: Thiago Macieira <thiago.macieira@intel.com> |

This directory contains autotests and benchmarks based on QTestlib. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
