- Delete include/cef_runnable.h (issue #1336). - Build the cef_unittests target using all Chromium headers. Add a USING_CHROMIUM_INCLUDES define and libcef_dll_wrapper_unittests target to support this. This change avoids compile errors due to the divergence of CEF and Chromium base/ header implementations. The libcef_dll_wrapper sources must now compile successfully with both CEF and Chromium base/ headers (issue #1632). - The onbeforeunload message specified via JavaScript is no longer passed to the client (see http://crbug.com/587940).

// Implementation details of COMPILE_ASSERT:
|
|
//
|
|
// - COMPILE_ASSERT works by defining an array type that has -1
|
|
// elements (and thus is invalid) when the expression is false.
|
|
//
|
|
// - The simpler definition
|
|
//
|
|
// #define COMPILE_ASSERT(expr, msg) typedef char msg[(expr) ? 1 : -1]
|
|
//
|
|
// does not work, as gcc supports variable-length arrays whose sizes
|
|
// are determined at run-time (this is gcc's extension and not part
|
|
// of the C++ standard). As a result, gcc fails to reject the
|
|
// following code with the simple definition:
|
|
//
|
|
// int foo;
|
|
// COMPILE_ASSERT(foo, msg); // not supposed to compile as foo is
|
|
// // not a compile-time constant.
|
|
//
|
|
// - By using the type CompileAssert<(bool(expr))>, we ensures that
|
|
// expr is a compile-time constant. (Template arguments must be
|
|
// determined at compile-time.)
|
|
//
|
|
// - The outer parentheses in CompileAssert<(bool(expr))> are necessary
|
|
// to work around a bug in gcc 3.4.4 and 4.0.1. If we had written
|
|
//
|
|
// CompileAssert<bool(expr)>
|
|
//
|
|
// instead, these compilers will refuse to compile
|
|
//
|
|
// COMPILE_ASSERT(5 > 0, some_message);
|
|
//
|
|
// (They seem to think the ">" in "5 > 0" marks the end of the
|
|
// template argument list.)
|
|
//
|
|
// - The array size is (bool(expr) ? 1 : -1), instead of simply
|
|
//
|
|
// ((expr) ? 1 : -1).
|
|
//
|
|
// This is to avoid running into a bug in MS VC 7.1, which
