* Mark ref-qualified members as always inlineThiago Macieira2015-10-073-20/+20
| | | | | | | | | | | | | MSVC and ICC on Windows always make calls to the dllexport'ed out-of- line copy of an inline function when compiling in debug mode. This creates an incompatibility when a compiler that understands ref- qualified member functions (such as ICC) is used to compile code using a DLL that was compiled with a compiler that doesn't understand (such as MSVC 2013).

* QMetaObjectBuilder: replace a QVector with std::vectorMarc Mutz2015-10-071-103/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ...with minimal other changes: signed/unsigned warning fixes, and API adjustments. I chose std::vector instead of QVector because it does not require the contained type to have a default constructor (QVector does). All three QMeta*Private types in question didn't have a default ctor before they were ported to be held in QVectors (instead of QLists). std::vector generally also produces less executable code, and its push_back() is overloaded for rvalue references, and the code happens to pass only QMeta*Private temporaries to it, which are conveniently implicitly move-enabled. Even though std::vector doesn't care, keep the QMeta*Private classes marked as Q_MOVABLE_TYPE, so the next person doesn't wonder whether it was forgotten or intentional. There are a lot of for loops which use int-based indexing. They all needed to be adjusted to use size_t-based indexing. Eventually, we will change that to C++11 range-for loops. In most places, index validation could now be done in a single unsigned comparison, but keep that for a separate commit to keep the change minimal. Added lots of casts to int from size_t to avoid MSVC's narrowing conversion warnings. Saves more than 4.5K of text size on GCC 4.9 optimized C++11 AMD64 Linux builds.

| * Fix deadlock on disconnectNotify() called from ~QObjectThiago Macieira2015-09-253-13/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, disconnectNotify() is called at the end of QObject::disconnect and all the locks have been dropped. That is not the case for the QObject destructor, so we need to deal with the fact that it there may be some locks held. I didn't catch this issue during testing because it depends on the pointer addresses of the object being destroyed and that of the QDBusAbstractInterface sender object, as we use one global, non- recursive mutex pool. For the same reason, this patch is not testable. The fix is simple: we don't need to remove the relay rules immediately. It's ok for them to happen later, since the worst case scenario is that we'll receive a few more signals than we have objects to deliver them to. If that happens, we'll do a little more work than we have to. But in the normal case, the amount of work is the same and we get the benefit of returning more quickly from the destructor. What's more, if the QDBusAbstractInterface object also gets destroyed, the events are deleted and QDBusConnectionPrivate will clean everything up.

| * Add code to perform overflow-checking additions and multiplicationThiago Macieira2015-09-232-0/+120

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.

| * windows: Improve error handling with EGLLaszlo Agocs2015-09-231-12/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When disabling the graphics adapter, things start failing with context lost and then bad_alloc and bad_access failures when creating contexts/window surfaces. Swap buffers now handles context loss. This makes it possible for Qt Quick to act when the graphics adapter goes away. Similarly, the window surface creation failure EGL_BAD_ACCESS is treated the same way as context loss. Note that this will not really help the main issue, because rendering is not possible without a GPU (reinit attempts will fail either at context creation or window surface creation), but proper logging and context loss reporting improves the situation somewhat. Also unify and prettyify the warning and debug prints. This makes it easier to understand what is going on.
