* qcompilerdetection.h: stream-line MSVC feature detectionMarc Mutz2012-08-261-6/+9
| | | | | | | | | | | | | | | | | Reformat the MSVC feature detection to be similar to other compilers, ie. 1. Inside the C++11 features section instead of where the compilers are detected 2. In one block for the compiler, with sub-blocks for the version. However, it's now not 100% compatible with the previous version, since Q_CC_INTEL is now explicitly excluded while before it was implicitly included in the MSVC case. I have no idea whether that matters, since Q_CC_INTEL is handled for itself further up already. Change-Id: Id9e8da0a5394ad5643bcb29493f14bc6e8264c13 Reviewed-by: Olivier Goffart <ogoffart@woboq.com>

* Logging: make qEmergencyOut() not allocate from the heapMarc Mutz2012-08-231-11/+38
| | | | | | | | | | | | | | | | | | | | | Commit 6e6b74c0 introduced heap allocation in the form of QString::fromLatin1().utf16() into qEmergencyOut(), a function that's called in OOM situations and in cases where another exception is still in flight. Luckily, QString::fromLatin1().utf16() is just a funny way of copying an array of chars into an array of wchar_ts, so we do that manually now and use a static wchar_t buffer. While at it, also throw text elision into the mix. This commit also fixes the message passed to _CrtDbgReportW(). What should be displayed is the emergency_buf, not the format string. Also remove a similar allocation in qt_message_output(). Change-Id: I2c44a298fc0927bb992de4977a7e4a7b47b16b26 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* Do not consider sign in qIsNull.Mitch Curtis2012-08-221-4/+4
| | | | | | | | | | | | | | | The current implementation of qIsNull only returns true if the value is positive zero. This behaviour is not useful for use cases like QPointF::isNull, where QPointF(-0, -0).isNull() will return false. There doesn't seem to be a reason why the function exhibits this behaviour (-0.0 is not accounted for in the unit tests), and for the case of QSizeF::scale it causes a bug: qIsNull is used to check for division by 0.0 before it proceeds, which fails in the case of -0.0.

| | | | | | | | | | | | | | | | Commit 7315296e9c94c38c842728aed199ac286a3ef174 blacklisted GCC 4.6.0 and 4.6.1 on the grounds that the bug regarding noexcept was fixed in 4.6.2. However, we have evidence of the issue remaining in 4.6.3, so it looks like it was not the issue that the GCC team fixed. For that reason, declare noexcept support in GCC 4.6 fatally broken and enable it only for 4.7. It has been working fine for a month for me on 4.7.1.

| | | | | | | | | | | | | | | | | | | | | | These functions are not supposed to return, not even by exception. qt_message() _can_ throw, but we're fine with the compiler calling std::terminate() then, since the backtrace will still include the assertion location. This behaviour is ensured by a new macro, QT_TERMINATE_ON_EXCEPTION, which expands to something like try { expr; } catch(...) { std::terminate(); } if the compiler doesn't support Q_DECL_NOEXCEPT (but maybe Q_DECL_NOTHROW), and to something like just expr; otherwise (including in the QT_NO_EXCEPTION case). The real macro preserves scopes in all cases, and aims to work even if <exception> isn't included in the TU it's used in, so is a little bit more complex than that.

* Q_DECL_NOTHROW: stronger and more widely available version of Q_DECL_NOEXCEPTMarc Mutz2012-08-072-4/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 1adca807 defined Q_DECL_NOEXCEPT to be the same as throw() for the Microsoft compiler. However, the two are not equivalent: - C++11 noexcept is defined to call std::terminate() if a noexcept function nevertheless encounters an exception. - MSVC throw() has essentially undefined behaviour in this situation: http://msdn.microsoft.com/en-us/library/wfa0edys%28v=vs.100%29 "Due to code optimizations that might be performed by the C++ compiler [...] if a function does throw an exception, the program may not execute correctly." So define two macros: 1. Q_DECL_NOEXCEPT/Q_DECL_NOEXCEPT_EXPR always have C++11 behaviour. This is expected to be the more efficient implementation if the function can actually throw. 2. Q_DECL_NOTHROW means that the function gives the nothrow guarantee. It is stronger than noexcept, but not all functions that can be marked Q_DECL_NOEXCEPT can be marked Q_DECL_NOTHROW. In general Q_DECL_NOTHROW functions need to use a try/catch block in order to prevent exceptions from leaving the functions, unless you can proove that none of the operations can throw. For the caller, both macros are equivalent: it can be relied on that no exception leaves the function.
