28fab27503 add AA_CompressHighFrequencyEvents to control compression on xcb
7edd10e6c added this compression feature, but some applications may
need to disable it.

[ChangeLog][X11] It's now possible to unset AA_CompressHighFrequencyEvents
to disable the new X event compression feature that was added in 5.6.0.
This is a replacement for the WA_NoX11EventCompression flag in Qt 4.

81793b8b58 Add QT_NO_FOREACH to disable foreach and Q_FOREACH
It has been known for a long time that Q_FOREACH produces
inferior code to other looping constructs, and the use of it
in Qt library code was informally frowned upon since forever
(pun intended).

Yet, to this day, several thousand foreach/Q_FOREACH loops
have been added to Qt libraries, and while many were ported
to range-for in Qt 5.7, there are still new ones added every
day, which is a nuisance, to say the least.

This patch introduces a technical way to prevent new foreach
use to creep into Qt libraries after they have been cleaned,
by simply not defining either Q_FOREACH or foreach when the
QT_NO_FOREACH macro is defined. This way, one library at a
time can be ported away, and, once ported, is guaranteed to
actually stay ported.

75d65600f9 Work around ICC's bug in making std::atomic a literal type
ICC 15.x and 16.0 (beta, at least) are missing the "constexpr" and
"noexcept" keywords in the definition of the std::atomic
constructors. The lack of constexpr makes std::atomic a non-literal
type, which in turn makes QBasicAtomicInteger's constructor (which is
constexpr) fail to compile.

Reported as Intel issue 6000117277.

e1d0da6526 Fix Clang -Wexpansion-to-defined warning by deprecating QT_SUPPORTS
The C and C++ standards say it's undefined whether the preprocessor
supports macros that expand to defined() will operate as an ifdef.
Clang 3.9 started complaining about that fact.

One solution was to change QT_SUPPORTS to check for zero or one, which
means we need to change the #defines QT_NO_xxx to #define QT_NO_xxx 1.
The C standard says we don't need to #define to 0, as an unknown token
is interpreted as zero. However, that might produce a warning (GCC with
-Wundef), so changing the macro this way is not recommended.

Instead, we deprecate the macro and replace the uses with #ifdef/ndef.

ea97a43175 QOpenGLContext: add a way to disable the thread affinity check
The problem of the check is that it makes Qt non compliant with OpenGL
thread affinity semantics. One is allowed to make a GL context
current on any thread, without the Qt-specific idea of moving
the QOpenGLContext to that thread first. Moreover, the move is
plain impossible if the user needs to handle the context
to 3rd party code which assumes the context to have GL semantics.

Add an application flag to disable that.

54d95d0988 Fix UB (data race) in Q_GLOBAL_STATIC
The store to guard in the inner function's critical
section was not synchronized-with the load at the
start of the function:

    T1                    T2
    guard.load()
    mutex.lock()
    guard.load()
    d = new Type
    guard.store()
                          guard.load()
                          // use d
    mutex.unlock()

The use of d in T2 does not synchronize with
the write to d in T1 -> data race -> UB.

Fix by storing with release memory ordering,
so that the guard.load() in T2 synchronizes
with the guard.store() in T1.

31c7b24aa5 Silence MSVC warnings when using certain std algorithms
The MSVC STL warns when passing naked pointers as non-bounded
iterators to algorithms such as std::equal and std::copy, in
an attempt to inform users that the range specified by that
iterator has an implicit minimum size that the caller of the
algorithm must ensure is met:

  warning C4996: 'std::_Equal1': Function call with parameters that may be unsafe - \
  this call relies on the caller to check that the passed values are correct. To \
  disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to \
  use Visual C++ 'Checked Iterators'

When building Qt, as well as when building user projects with
qmake (cf. 0a76b6bc7f), we
globally disable this warning (with -D_SCL_SECURE_NO_WARNINGS),
but since we started using STL algorithms in public headers (e.g.
in qvector.h), users get this warning in their own projects now,
unless they, too, define said macro. But such a requirement is
against the Qt policy to have headers that are warning-free as
much as possible.

The suggested way of fixing this warning is to wrap the naked
pointer in a stdext::unchecked_array_iterator before passing it
to the algorithm, cf. examples in

  https://msdn.microsoft.com/en-us/library/ttcz0bys%28v=vs.120%29.aspx

or, together with the capacity-made-explicit, in a
stdext::checked_array_iterator.

To avoid ifdefs for platforms that don't have these extensions
(which, incidentally, for the unchecked case, includes MSVC 2012),
wrap the calls in macros.

The end game here is to drop -D_SCL_SECURE_NO_WARNINGS, at least
for public headers, even though this commit also adds the wrapper
to implementation and private header files.

An alternative to the wrapper would have been the version of
std::equal that takes four iterators. However, that is a C++14
library feature, while this version of Qt still needs to compile
with a C++98 compiler, and, more importantly, there isn't, and
never will be, a corresponding 4-iterator version of std::copy.

8093da2e51 Append the Windows OS/kernel version number in QSysInfo::prettyProductName().
The rationale is to be consistent with other operating systems, all of which
print a version number following their name (possibly in parenthesis if the
version is typically non-numeric as is always the case with OS X so far and
has been with Windows).

The version number printed here is only two digits, both for consistency with
OS X and because the first two digits of an operating systems's version are
typically the limit in marketing materials and general presentation.

This also fixes a bug where the returned string would be "Windows " (note the
space) in the case where the name of a future Windows version was not known.

[ChangeLog][QtCore][QSysInfo] The output of QSysInfo::prettyProductName
now includes the Windows OS/kernel version number. In case of future versions
of Windows, a valid string is now returned.

17ad6e2a93 Fix build when Qt is used in an automatic reference-counted environment
When automatic reference-counting (ARC) is enabled on Darwin platforms
the NSAutoReleasePool class should not be used directly, which caused a
build error if qglobal.h was included after the Foundation.h in client

The preferred alternative for ARC is the scoped @autoreleasepool
construct, which allows the compiler to reason about needing to
insert _objc_autoreleasePoolPush and _objc_autoreleasePoolPop
calls.

Note that ARC translation units can be combined with non-ARC translation
units, so Qt and the QMacAutoReleasePool class can still be used in
ARC client code even if Qt is not built with ARC.

f931e5e72d add cross-platform tablet->mouse event synth; enable on Android
It's urgent to fix the issue that on Android, it became impossible
to interact with any widget or MouseArea which handles only mouse
events but not tablet events, using the stylus, because stylus events
are sent only as QTabletEvents.  Before 5.6 (change
01d78ba86a) they were sent as
touch events, and mouse events were synthesized from those.  Whereas
on other platforms, every QTabletEvent is followed by a synthesized
QMouseEvent.

This fix proceeds in the direction that event synthesis should be done
in cross-platform code so that platform plugins don't have to repeat it,
following the same pattern as for touch->mouse synthesis.  Just as
in that case, the application can disable it, and the platform plugin
can also report that it's unnecessary for Qt to do the synthesis
because the platform already does.

So QTBUG-51618 is fixed, but QTBUG-47007 requires us to remove the
tablet->mouse synthesis from all platform plugins, because the plugin
does not know whether the tablet event was accepted or not, so it does
not have enough information to decide whether to synthesize a mouse
event.  Synthesis has been unconditional until now, which contradicts
what the documentation says: the mouse event should be sent only if
the tablet event is NOT accepted.  We can now gradually make this
promise come true.

[ChangeLog][QtCore][Tablet support] A synthetic mouse event will
no longer be sent after every QTabletEvent, only after those which are
not accepted (as documented).

b333c3396a qdoc: Remove Q_QDOC for qRound() and qRound64()
These uses of Q_QDOC cause clang to report syntax errors.
They are used to hide function return values as qreal
instead of using double and float. The decision is to be
more transparent and use double and float in the docs
instead of qreal.

This change does not require clang in qdoc.

6c54e10144 Qt Meta macros: Allow tools to define annotations
This might be useful for IDE or other tools to be made aware of Qt macros.

This is inspired to what QtCreator[1] and moc-ng[2] does. But they are forced
to redefine or inject code at precise location which might be difficult.

This is going to make it easier to use libclang in qdoc.

With this change, the tooling can just predefine the macro QT_ANNOTATE_FUNCTION
and QT_ANNOTATE_CLASS to get what they need.

Example with libclang:
 "-DQT_ANNOTATE_CLASS(type,...)=static_assert(sizeof(#__VA_ARGS__),#type);"
 "-DQT_ANNOTATE_CLASS2(type,a1,a2)=static_assert(sizeof(#a1,#a2),#type);"
 "-DQT_ANNOTATE_FUNCTION(a)=__attribute__((annotate(#a)))"
 "-DQT_ANNOTATE_ACCESS_SPECIFIER(a)=__attribute__((annotate(#a)))"
 "-DQ_CLASSINFO(name,value)=static_assert(sizeof(name,value),\"qt_classinfo\");"
 "-DQ_REVISION(v)=__attribute__((annotate(\"qt_revision:\" QT_STRINGIFY2(v))))"

%{time}%{time process}%{time boot} ended up to be output as if

This fix keeps the arguments of each individual 'time' part.

The same holds for multiple 'backtrace' parts. The previouse
implementation overwrote multiple 'backtrace' arguments with the
arguments of the last occurrence.

This fix keeps the individual arguments for the 'process' parts.

The individual arguments are applied in qFormatLogMessage.

f253f4c331 Track target widget when wheel events are received
This issue is reproducible on OS X when using a Magic Mouse
or a combination of Magic Trackpad and regular mouse. In these
cases it's possible to start a scrolling gesture on one widget
and move the mouse cursor over another widget.

Although we send the wheel event phase information, we never
made any use of it. This means that a widget would start
scrolling even though it never received a ScrollBegin event.

In this patch, we make sure the scrolling cycle is respected
and that once a widget starts scrolling, it'll be recieving
all the wheel events until a ScrollEnd event reaches the
application.

For those input devices not supporting a proper phase cycle,
we introduce a new (undocumented) phase value, NoScrollPhase.
If the wheel event phase is NoScrollPhase, then we ignore
the current scroll widget and proceed as usual. This value
is the default for wheel events. It's up to the platform
plugin to set the proper phase value according to the data
received from the OS.

Finally, we fix a few of QWheelEvent constructors to properly
initialize the phase and source properties.

a single library, libsystemd. To ease the transition one could pass
an option to its build to generate stub libraries and matching
pkg-config files. With systemd >= 229 this option has now been
removed, causing the build to fail when the journald option is
enabled.

3726c46735 Work around Clang < 3.7 integrated assembler bug PC-relative relocs
The qversiontagging.h inline assembly expands to:

  .long qt_version_tag@GOTPCREL

Which, with GCC, Clang >= 3.7 and with the option -no-integrated-as in
previous versions, produces the proper relocation (a R_X86_64_GOTPCREL).
With Clang < 3.7, it instead produces a R_X86_64_32, which is unsuitable
for use in shared libraries: 32-bit displacement is insufficiently wide
and would produce linker errors like

 obj/qftp.o: requires dynamic R_X86_64_32 reloc against 'qt_version_tag' which may overflow at runtime; recompile with -fPIC

Instead, force a 64-bit relocation (an R_X86_64_GOT64), which like the
32-bit version is simply an offset into the GOT of where the address of
the symbol is stored.

1c0494e63b QIODevice: add infrastructure for multistreaming
Some sequential devices allow data to be partitioned into several
channels that have the property of independently sequenced delivery.
Supporting such devices uniformly requires a unified API which provides
the user with a uniform concept of multistreaming.

This patch is based on QProcess's multiplexing model and introduces
the following features:

 - ability to get the number of channels;
 - multiple internal read/write buffers;
 - channel selection functions;
 - notification signals on channel activity.

To keep the source code compatible with single-channel implementations,
introduce a private class that references the current read buffer and
hides multistreaming internals from the user.

Bump the TypeInformationVersion field in qtHookData, to notify the
Qt Creator developers that the offset of QFilePrivate::fileName was
changed and dumpers should be adapted.

[ChangeLog][QtCore] Added multistreaming to QIODevice.

Therefore, it is necessary to check both whether it is defined and if it is
not 0. Only checking whether a given macro is 0 will generate a trap by
-Werror=undef.

(__GLIBCXX__ is the sole exception).

7d257aab81 QIODevice: handle incomplete reads
Introduce a transaction mechanism that gives the ability to read the
data atomically. Current implementation supports transactions for both
types of devices. For sequential devices, it records the whole input
stream during transaction. For random-access devices, device position
is saved when transaction starts. If an error occurs, the application
may be able to recover the input stream by rolling back to the start
point.

Also, QIODevice::peek() was rewritten to make use of transactions
internally. The replacement of QIODevicePrivateLinearBuffer by
QRingBuffer is closely entangled with that, which makes it unfeasible
to do separately.

Bump the TypeInformationVersion field in qtHookData, to notify the
Qt Creator developers that the offset of QFilePrivate::fileName was

264c72837d Add qAsConst
...to turn mutable lvalues into const lvalues.

Like the proposed std::as_const, it should not apply to
rvalues to avoid lifetime issues in code like

     for (auto x : qAsConst(someFunc()))
         // dangling

At a more basic level, qAsConst isn't useful for rvalues,
because one can always store them in an lvalue first, with
no loss in performance (the object is created by the
compiler silently anyway). So the correct way to write the
above is:

    const auto funcResult = someFunc();
    for (auto e : funcResult)

To fail compilation when passing rvalues, I used the
const-&& pattern also employed by std::cref(), and the
proposed std::as_const.

Intended as internal API, but not put into the QtPrivate
namespace to make it simpler to use.

We could wait for std::as_const, but that is far, far
away (just entered the current C++17 draft as of this
writing), and the Qt containers with their tendency to
detach are a problem _now_.

1005b7a0de Long live qUtf16Printable()
QString::asprintf() has the ability to take a ushort* array as
obtained from QString::utf16() and insert that into the output
with an %ls conversion.

But no-one ever used this, because just passing QString::utf16()
to QString::asprintf() creates a warning about wchar_t* expected,
but ushort* provided.

The new qUtf16Printable() macro adds the necessary casts (via void*
to prevent any "type-punned pointer" warnings) to make
passing QString::utf16() to QString::asprintf() work silently.

This should greatly reduce the need to do a round-trip via utf-8
just to print the contents of a QString.

[ChangeLog][QtCore] Added qUtf16Printable().

5ff7a3d96e Add {add,sub,mul}_overflow for signed integers.
In C++, signed overflow math is Undefined Behavior. However, many CPUs
do implement some way to check for overflow. Some compilers expose
intrinsics to use this functionality. If the no intrinsic is exposed,
overflow checking can be done by widening the result type and "manually"
checking for overflow. Or, for X86, by using inline assembly to use the
CPU features.

Used in QtQml.

add58edcdb Update high-DPI scaling enablers.
Make it possible to enable and disable both at the
environment variable level and at the source code
level. This applies to scaling done by Qt using display
density information provided by the operating system.

Disabling is done with a 'veto' system: both the environment
and source code my prevent the other for enabling
scaling. This covers use cases of 'my system does not
provide correct display metrics' and 'my application
needs access to display pixels', respectively.

On the environment, scaling is now enabled with
QT_AUTO_SCREEN_SCALE_FACTOR=1 and disabled with
QT_AUTO_SCREEN_SCALE_FACTOR=0. In source code the
corresponding application attributes are AA_EnableHighDpiScaling
and AA_DisapleHighDpiScaling. Not setting any of these
indicates 'no preference'.

The global scale factor set by QT_SCALE_FACTOR is
not affected by any if the disablers.

d020e0781c Workaround: don't create ELF version scripts for Android
Somehow qmake doesn't add the correct rules for the Android makefiles,
so the build fails when cross-compiling from Windows. The reason for
that is unknown (could be related to that "qt_android_deps" config, but
that isn't used anywhere in qmake or the buildsystem).

This isn't likely to be a problem, since there are no global installs of
Qt on Android.

because it did not work for multiarch systems (when we supported fat

might be different when cross-compiling.

Instead, let's rely on the predefined preprocessor macros to detect
correctly. As a nice side-effect, this fixes 64-bit Android builds
cross-compiled from Windows.

bf92993829 Add an automatic use of the ELF-versioned QtCore symbol
See the comment in the header for an explanation of what it does.

This trick is enabled for every single .o that is compiled, unless
QT_NO_VERSION_TAGGING is defined. The assembly expands to a COMDAT
section, which is mergeable by the linker, so only one copy of the
output is present in the ELF module.

This is enabled only for Linux and x86 / x86-64 / x32 due to the
requirement of writing assembly and relocations, so it needs to be
tested on each platform, which I have not done. It might work on
Solaris/x86, but again it requires testing. Support for other
architectures requires different assembly output and relocations and can
be added as needed, but they are not as important since this trick is
has most value on desktop systems.

Anyway, this solution now works for all ELF architectures, independent
of the processor, whereas previously it was restricted to x86 and Linux/
FreeBSD. However, this does not apply to the assembly in
qversiontagging.h.

Most processors have carry flags which they set on addition overflow, so
it's a good idea to access them whenever possible. Most of them also
have widening multiply instructions that can be used to detect overflow
of the non-widening version.

Tested to compile on:
 Architecture     Compiler
  x86             GCC 4.9, GCC 5*, Clang 3.6*, ICC 16 beta
  x86-64          GCC 4.9, GCC 5*, Clang 3.6*, ICC 16 beta
  x86-64 ILP32    GCC 4.9, GCC 5*, Clang 3.6*
  IA-64 LP64      GCC 4.8
  ARMv7-A         GCC 4.9, Clang 3.6*
  AArch64         Clang 3.6*
  MIPS            GCC 4.9, Clang 3.6*
  MIPS64          GCC 4.9, Clang 3.6*
  PowerPC         GCC 4.9, Clang 3.6*
  PowerPC 64      GCC 4.9, Clang 3.6*
  SPARC           Clang 3.6*
  SPARCv9         Clang 3.6*

[*] supports the intrinsics

If the compiler does not offer a way to detect an overflow, we do it by
hand. For unsigned additions, that's easy, since the C++ language
specifies the behavior of the overflow. That's also the reason why this
code is implemented only for unsigned integers.

For the multiplication, if the compiler does not support widening
multiplications, we do it with a division instead. This is necessary for
GCC < 4.5 and compilers not compatible with GCC or MSVC.

dc716f2dc2 ICC on Windows: Disable ref-qualified member functions in MSVC <= 2013
Like MSVC, ICC on Windows in debug mode always makes calls to
dllexported functions instead of inlining them. Since MSVC 2013 doesn't
know about ref-qualification of member functions, this creates an
incompatibility between DLL creation and DLL use.

5081fd6887 Deprecate Q_OS_MAC.
Justification: intuition indicates that Q_OS_MAC refers to OS X. Reality
indicates it refers to OS X, iOS, watchOS, and tvOS. Technical
correctness requires that it match reality. Backwards compatibility
dictates it can't be changed anyways. Conclusion: an extremely confusing
macro that no one knows how to use properly.

When Q_OS_MACX was repurposed for OS X (and later, Q_OS_OSX introduced),
Q_OS_MAC was kept around to allow differentation between Q_OS_DARWIN
(the grandfather OS of everything - OS X, iOS, watchOS, tvOS, and
theoretically "open source Darwin derivative"). However, given that
every attempt at a non-Apple Darwin based operating system has failed
and sees virtually no interest at scale, this distinction is not useful
in Qt for the confusion it causes in return, especially considering that
there are several cases in Qt where Q_OS_MAC should be Q_OS_DARWIN or
vice versa, and sometimes the correct macro is not even entirely clear.

Therefore, Q_OS_MAC can be deprecated. In the extremely unlikely case
that differentiation between Darwin core, and commercial Darwin-based
operating systems from Apple is required, I suggest introducing
Q_OS_APPLE (a superset of Q_OS_DARWIN, and subset of Q_OS_OSX, Q_OS_IOS,
Q_OS_WATCHOS, and Q_OS_TVOS). Until it is needed, Darwin, OS X, iOS,
watchOS, and tvOS defines should be perfectly sufficient for every
real-world use case.

6de8c0aa09 Add a qt_version_tag symbol to QtCore that uses ELF versions
This symbol will exist with different ELF versions, allowing us to know
which version of Qt a given library or application was linked
against. When this symbol gets used, automatic packaging tools will
extract the dependency. The trick here is that the application uses
qt_version_tag without knowing which version is current, but the linker
resolves it to the current version and records that.

For example, if this were used with Qt 5.5, RPM's find-requires on an
application using QtCore would print:

  libQt5Core.so.5()(64bit)
  libQt5Core.so.5(Qt_5.5)(64bit)
  libQt5Core.so.5(Qt_5)(64bit)

Whereas find-provides on QtCore would print:

  libQt5Core.so.5()(64bit)
  libQt5Core.so.5(libQt5Core.so.5)(64bit)
  libQt5Core.so.5(Qt_5.0)(64bit)
  libQt5Core.so.5(Qt_5.1)(64bit)
  libQt5Core.so.5(Qt_5.2)(64bit)
  libQt5Core.so.5(Qt_5.3)(64bit)
  libQt5Core.so.5(Qt_5.4)(64bit)
  libQt5Core.so.5(Qt_5.5)(64bit)
  libQt5Core.so.5(Qt_5)(64bit)

Therefore, automatic dependency resolution would have the information it
needs to conclude that the application requires Qt >= 5.5.

It is sufficient to keep and test the actual data sets on the Qt Creator

So far, HookDataVersion was meant to be used for that purpose. To

the middle man and save one memcpy.

a705b4ec1f Introduce cross platform high-dpi scaling
Add a coordinate scaling layer to QtGui, which supports 'devicePixelRatio'
type high-dpi on all platforms, in production and also for
development and testing purposes.

High-DPI scaling is opt-in, by setting environment variables:
    QT_SCALE_FACTOR - sets a global scale factor
    QT_AUTO_SCREEN_SCALE_FACTOR - sets per-screen scale factors,
        where the scale factors are provided by the platform plugin.

This QtGui scaling can be used instead of or in addition to scaling
done by the window system. This distinction is not visible to
applications [when they use Qt API], which will see a change in
the value returned by the devicePixelRatio() accessors as usual.

Introduce a new (private to Qt) coordinate system: native pixels.
The coordinate system stack now looks like:
    device-independent pixels (app, upper parts of Qt)
    native pixels (lower parts of Qt Gui, platform plugins)
    device pixels (backing stores and OpenGL)

Add private QHighDpi namespace with scaling functions that convert
between device-independent pixels and native pixels:
    T toNativePixels(T, QWindow *);
    T fromNativePixels(T, QWindow *);

Add scaling calls the QWindow (and friends) cross-platform implementation,
around the calls to QPlatformWindow functions. QPlatformWindow now uses
native coordinates - platform code remains largely unchanged since native
coordinates are window system coordinates.

QWindow now uses (possibly) scaled coordinates. This means that
platform plugins no longer can rely on QWindow::geometry() and
related functions. QPlatformWindow::windowGeometry() and other
convenience functions have been added for use when the platform
plugin needs to convert scaled geometry to native geometry.

Add Qt::AA_NoHighDpiScaling, which can be use to disable any
scaling in QtGui, effectively ignoring the environment variables.
(Note that this does not disable any scaling done by the window
system.)

Contributions from Friedemann and Paul.

cf3a639f9d Improve ICC compatibility with older MSVC versions (up to 2010)
Like on OS X and Linux, ICC uses the native compiler's standard library
headers, so the C++11 features that depend on headers need special
attention.
 * <initializer_list> is missing with MSVC 2012. It is present on 2010
   for some reason and it appears to work
 * ICC disables Unicode string support prior to MSVC 2015, probably
   because MSVC Standard Library headers have a typedef for char16_t

std::nullptr and std::move should have come with MSVC 2010, but I'm not
keeping compatibility with MSVC 2008. It's been deprecated since ICC
14.0 (Composer XE 2013 SP1, released in 2013) and support was removed in
15.0 (Composer XE 2015, released in 2014). ICC hasn't supported MSVC
2005 since ICC 13.0 (Composer XE 2013).

final executable. Maybe -Wl,-pie would fix it.

6c20a01cb9 QSysInfo: Expand Linux distribution detection
Expand Linux distribution detection to /etc/redhat-release and
/etc/debian_version to follow what /usr/bin/lsb_release script does.
If /usr/bin/lsb_release fails to extract the distribution information
from /etc/lsb-release, it then checks /etc/redhat-release and, as a last
fallback, /etc/debian_version.

Some Red Hat distributions have a /etc/lsb-release file that
does not provide the values we are looking for (DISTRIB_ID,
DISTRIB_RELEASE and DISTRIB_DESCRIPTION).

If both productType or productVersion are empty after reading
/etc/lsb-release, readEtcLsbRelease() will return false, allowing
further parsing of /etc/redhat-release. This scenario mimics what
the /usr/bin/lsb_release script does if /etc/lsb-release does not
contains enough information.

The productType and productVersion returned by QSysInfo after reading
/etc/redhat-release match the distributor id and release information
returned by the /usr/bin/lsb_release script.

For Debian Linux distributions where /etc/os-release, /etc/lsb-release
and /etc/redhat-release are not available nor usable, the
/usr/bin/lsb_release script also checks for the /etc/debian_version
file.

In this case, we also enable parsing of /etc/debian_version to retrieve a
fallback productVersion, the productType being set to Debian.

3eca75de67 Make qglobal.h complain if you use -fPIE
Prior to Qt 5.4.2 (commit 36d6eb721e), we
allowed it, but now we need to enforce that it is not used. Note that
-fPIE does define __PIC__, so we need this to catch the use of -fPIE.

[ChangeLog][Important Behavior Changes] On x86 and x86-64 systems with
ELF binaries (especially Linux), due to a new optimization in GCC 5.x in
combination with a recent version of GNU binutils, compiling Qt
applications with -fPIE is no longer enough. Applications now need to be
compiled with the -fPIC option if Qt's option "reduce relocations" is
active. Note that Clang is known to generate incompatible code even with
-fPIC if the -flto option is active.

36d6eb721e Require -fPIC instead of just -fPIE for -reduce-relocations
GCC 5 combined with a recent binutils have a new optimization that
allows them to generate copy relocations even in -fPIE code. Clang has
the same functionality when compiling an executable with -flto. We need
to let the compilers know that they cannot use copy relocations, so they
need to use really position-independent code.

Position independent code throughout is not really required. We just
need the compilers to use position-independent access to symbols coming
from the Qt libraries, but there's currently no other way of doing that.

QTreeViews (and only there), hence the new name for it.

8272f5415b Fix crashes when accessing environment variables concurrently
We've seen crashes with QThreadPrivate::start using qgetenv during the creation
of the event dispatcher, while another thread (for example the gui thread)
called qputenv. This is inherently thread-unsafe and there are many places
where we make the assumption that using the environment is safe. However access
to the environment is inherently unsafe in the C runtime and the best that we
can do is add a mutex around the Qt environment access functions, to at least
protect ourselves and our users.

013afc77f0 Add Qt::WindowFlag to signal that maximizing should cover full screen geometry
Normally when maximizing a window it will cover the available geometry
of the screen, as represented by QScreen::availableGeometry(), which
typically excludes status/menu bars and application launchers.

On some platforms it may still be possible to place windows in the areas
of the screen that are outside of the available geometry, but this will
result in the window being partially covered by (possibly) transparent
system UIs. The new flag allows the user to specify that when maximizing
the window it should try to cover as much as possible of the screen
geometry (in contrast to going full screen, which would typically
hide any system UIs).

For iOS this is a common use-case, as the status bar is transparent,
and the user-interface guidelines for iOS7 and up recommend taking
advantage of the full screen space, while keeping any user-interaction
elements still inside the available geometry of the screen.

brings the behavior to match strtoll and strtoull on Linux, including
the fact that strtoull will parse negative numbers. For that reason,
qstrtoll and qstrtoull are now wrappers that try and keep the behavior
that we used to have.

This update also changes the code from a 4-clause BSD license (bad) to a
3-clause BSD license (good).

9a3d7adaad Fix -Wunreachable-code warning from clang in preprocessed Q_ASSERT
Q_ASSERT expands to:
 do {} while (false && (<your condition>))

Which is fine for Clang as long as it's a macro. However, when you
compile as a preprocessed source, the macro is gone and Clang prints the
warning:

 warning: code will never be executed [-Wunreachable-code]
 do {} while (false && (f()));
                        ^
 note: silence by adding parentheses to mark code as explicitly dead

So add the parentheses that it's asking about.

The changelog refers to the full Q_ASSERT change from
ebef2ad136.

[ChangeLog][Important Behavior Changes] Q_ASSERT will now expand the
condition even in release mode when asserts are disabled, albeit in an
unreachable code path. This solves compiler warnings about variables and
functions that were unused in release mode because they were only used
in assertions. Unfortunately, codebases that hid those functions and
variables via #ifndef will need to remove the conditionals to compile
with Qt 5.5.

04ec8134e8 Haiku: Use 'unknown' as QSysInfo::productType()
There are no actual products of Haiku, so using
'unknown' (the default) is fine, otherwise the
file platform selector would be '+unix/+haiku/+haiku'
instead of '+unix/+haiku'.

c38b6a3fde Disable constexpr support for QNX
Even though the compiler on QNX supports C++11, the stdlib it ships
with is missing constexpr on many important functions. This is required
to make qtbase compile on QNX 6.6.

b584648df1 Use Clang 3.6's __builtin_assume in Q_ASSUME
It's more efficient than the current implementation. Example:

int f(int i)
{
    Q_ASSUME(i < 8);
    return i < 8;
}

Before:
        cmpl    $8, %edi
        setl    %al
        movzbl  %al, %eax
        retq

After:
        movl    $1, %eax
        retq

fbeeaf23fe Introduce QT_NO_MIMETYPE
The mime type stuff generates one of the biggest translation units in QtCore
due to the compressed 1.7MB freedesktop.org.xml resource.

With QT_NO_MIMETYPE, libQt5Core.so is almost 400Kb smaller
(4.8MB->4.4MB gcc 4.9 stripped release build)

2be0d3088f qFormatLogMessage: optimize %{backtrace}
backtrace_symbols is very slow because it tries to find the function
name from the address. In order to do that it needs to do a linear search
over all symbols. (Because the hash table goes the other way to find the
address from the symbol name)

The code is going to skip a few frames from QtCore. Since we cannot know
how many, we take a few more than necessary.
This patch changes the additional number of frames from 15 to 7
(Usually, there are about 5 suppressed frames).

We call backtrace_symbols several times for only one frame at the time.
So we are not looking up addresses we don't need after we printed the
right number of frames.

Calling many times backtrace_symbols means we do more malloc, but that's
negligible compared to the time we save. We anyway do a lot of other
allocations because of the regexp operations and such

So this patch is then saving about 10 frames lookups which allow to print
about 6 qDebug per miliseconds instead of only 2 when using %{backtrace depth=2}

db631a88a0 Avoid hardcoding build date in qtcore and tools
To ensure QtCore can be rebuilt and get the exact same results,
it is undesirable to hardcode the build date into the library

Also deprecate QLibrayInfo::buildDate since it is relies on the build
date. QLibraryInfo::buildDate was originally meant for evaluation
licenses and such, but isn't used for that any longer.

86c6804a41 QNX: fix compiler detection.
Short version: fix build on QNX 6.5.0.

C++11 has been included on QNX 6.6.0's libcpp (Dinkum C++11 libs), while
continuing to be unsupported by the older QNX 6.5.0 toolchain.

This patch updates the mechanism for detecting the QNX's libcpp that is being
used during compile time, and also updates the list of C++11 features to be
disabled when QNX C++11 support is not present by adding
Q_COMPILER_UNICODE_STRINGS and Q_COMPILER_NOEXCEPT to it.

bcfb535e82 QLogging: avoid a needless check
QString::vasprintf() deals just fine with a nullptr format string,
so don't check manually.

The main advantage of dropping the check is that in two of three
cases, we can replace assignment with initialization, thus saving
one default ctor and one (move) assignment.

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

Outdated header.LGPL removed (use header.LGPL21 instead)

Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)

Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination
