* Fix UB (data race) in Q_GLOBAL_STATICMarc Mutz2016-05-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Silence MSVC warnings when using certain std algorithmsMarc Mutz2016-04-261-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. 0a76b6bc7f98900ea884cd10ccca1a332e5bdba5), 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.

* Fix build when Qt is used in an automatic reference-counted environmentTor Arne Vestbø2016-04-131-5/+1
| | | | | | | | | | | | | | | | | | | | | 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 code. 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.

* Qt Meta macros: Allow tools to define annotationsOlivier Goffart2016-04-061-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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))))" [1] qt-creator/cplusplus/wrappedQtHeaders/QtCore/qobjectdefs.h [2] https://code.woboq.org/mocng/src/qobjectdefs-injected.h.html Change-Id: I88fcb28f1dbb3d26ea82f10e9948e68a18c795e9 Reviewed-by: Nikolai Kosjar <nikolai.kosjar@theqtcompany.com> Reviewed-by: Kevin Funk <kevin.funk@kdab.com> Reviewed-by: Milian Wolff <milian.wolff@kdab.com> Reviewed-by: Thiago Macieira <thiago.macieira@intel.com> Reviewed-by: Jędrzej Nowacki <jedrzej.nowacki@theqtcompany.com>

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. A new test to verify the individual 'time' arguments application is added, too.

* Track target widget when wheel events are receivedGabriel de Dietrich2016-02-292-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* Workaround: don't create ELF version scripts for AndroidThiago Macieira2015-10-291-1/+1
| | | | | | | | | | | | | 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. Change-Id: I1d0f78915b5942aab07cffff140f95ce32324030 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* Move pointer size detection entirely to qprocessordetection.hThiago Macieira2015-10-263-23/+28
| | | | | | | | | | | | | | | | This commit removes the legacy ptrsize check, which was deficient because it did not work for multiarch systems (when we supported fat OS X binaries) and did not work for bootstrap builds because the size 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.

* Add an automatic use of the ELF-versioned QtCore symbolThiago Macieira2015-10-203-1/+89
| | | | | | | | | | | | | | | | | | | | | | 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.

* Update qversiontagging.cpp not to use too much assembler magicThiago Macieira2015-10-202-57/+50
| | | | | | | | | | | | | | | The only reason I had used them in the first place was because C preprocessor macros cannot call themselves recursively. But the magic was too magic and caused issues with some builds, so let's choose the safer option. 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. Change-Id: I42e7ef1a481840699a8dffff1404f032fc5cacb8 Reviewed-by: Lars Knoll <lars.knoll@theqtcompany.com>

| | | | | | | | | | | | | | | | | | | | | | | | 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.
