Marc Mutz 6da6a17de9 Fix qHash(qfloat16) to match Qt 6.4 behavior There were two problems: - On platforms where QFLOAT16_IS_NATIVE == true, a qHash(qfloat16{}) call has become ambiguous between the three FP qHash() overloads (float, double, long double), where it was unambiguously calling the float one in Qt 6.4. This SiC was caused by the replacement of operator float() by operator __fp16() in `99c7f0419e`, which is in Qt 6.5. - On platforms where QFLOAT16_IS_NATIVE == false, qHash(qfloat16{}) would produce a different value from qHash(float{}), and therefore Qt 6.4, when the seed was != 0, because the former would go via the one-arg-to-two-arg qHash adapter while the latter one would not. Since participating functions are inline, this causes old and new code to produce different hash values for the same qfloat16, leading to a BiC possibly corrupting QHash etc. Fix both by adding an explicit qHash(qfloat16). This function is inline, so it doesn't add a new symbol to 6.5.x. [ChangeLog][QtCore] Fixed qHash(qfloat16) which was broken from 6.5.0 to 6.5.3, inclusive. If you compiled against one of the affected Qt versions, you need to recompile against either Qt 6.4 or earlier or 6.5.4 or later, because the problematic code is inline. Pick-to: 6.6 6.5 Fixes: QTBUG-116064 Fixes: QTBUG-116076 Change-Id: Id02bc29a6c3ec463352f4bef314c040369081e9b Reviewed-by: Volker Hilsheimer <volker.hilsheimer@qt.io> Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>		2023-09-12 21:12:50 +00:00

This directory contains autotests and benchmarks based on Qt Test. 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.
