QString::compare_helper(QChar*, int, char*, int), but got
the case wrong where the rhs is null, but the lhs is empty,
not null (which is the case even with a null QString, as
QString().constData() != nullptr). The correct result in

equal.
Fix by checking the length of lhs, not its pointer.

Font style names are quite irregular and the simplistic matching
implemented in QFontDatabase::styleString(const QFont &) is unable to
properly resolve the style name when font is recreated from a string.

made to write and respect the exact font style.

One of the good features of the new connection style is that
implicit conversion is performed for the connection arguments.
However, this is also a bad feature when it comes to the old
C remnants in the C++ language: for instance, doubles implicitly
convert to ints, possibly losing precision (and GCC/Clang do not
even warn about those under -Wall, only MSVC does) or even
triggering undefined behavior.
For this reason, when using braced initialization, C++11
disables narrowing conversions or floating/integral conversions.
Use this feature when checking the arguments of a PMF-style
signal/slot connection. Technically this makes the program
ill-formed, however GCC still accepts it (but at least
warns under -Wall).
Hence, add a way to disable these implicit conversions.
This is a opt-in and guarded by a macro, as it's a source
incompatible change.
[ChangeLog][QtCore][QObject] The
QT_NO_NARROWING_CONVERSIONS_IN_CONNECT macro has been added.
When using the new connection syntax (PMF-based) this macro
makes it illegal to narrow the arguments carried by the signal,
and/or to perform floating point to integral implicit
conversions on them. When the macro is defined,
depending on your compiler a QObject::connect() statement
triggering such conversions will now fail to compile.

There was a race condition between QObject::disconnect() and
QMetaObject::activate() which can occur if there are multiple
BlockingQueued connections to one signal from different threads and
they connect/disconnect their connections often.
What can happen in this case is:
T1 is in activate() method and T2 is in disconnect() method
T1 T2
locks sender mutex
selects next connection
unlocks sender mutex
locks sender mutex
sets isSlotObject to false
creates QMetaCallEvent derefs connection
posts event
Two things can happen here:
1. Connection can still be valid, but it will have isSlotObject==false
and callFunction will be used instead of slotObj
2. Connection can already be invalid
To fix it mutex unlock should be moved after QMetaCallEvent creation.
Also there is another case, when we don't disconnect but delete the
receiver object. In this case it can already be invalid during
postEvent, so we need to move mutex unlock after postEvent.

C preprocessors augment their standard list of include paths from the

$CPLUS_INCLUDE_PATH (for C++), plus CPATH for both, whereas MSVC uses
the an environment variable simply called "INCLUDE". Handling this for
MSVC is particularly important because the VCVARSALL.BAT script sets the
necessary #include paths in the environment for important things.

In order for moc to properly parse #ifdefs and family, we've had
QMAKE_COMPILER_DEFINES as a list of pre-defined macros from the

Instead, let's simply ask the compiler for the list. With GCC and
family, we use the -dM flag while preprocessing. With ICC on Windows,
the flag gains an extra "Q" but is otherwise the same. For MSVC, it
requires using some undocumented switches and parsing environment
variables (I've tested MSVC 2012, 2013 and 2015).
The new moc option is called --include to be similar to GCC's -include
option. It does more than just parse a list of pre-defined macros and
can be used to insert any sort of code that moc needs to parse prior to
the main file.
