The child acquires the write end of the pipe and signals the parent -// using a Windows event. -// 4. Now the parent can release the write end of the pipe on its side. If -// this is done before step 3, the object's reference count goes down to -// 0 and it is destroyed, preventing the child from acquiring it. The -// parent now has to release it, or read operations on the read end of -// the pipe will not return when the child terminates. -// 5. The parent reads child's output through the pipe (outcome code and -// any possible error messages) from the pipe, and its stderr and then -// determines whether to fail the test. -// -// Note: to distinguish Win32 API calls from the local method and function -// calls, the former are explicitly resolved in the global namespace. -// -class WindowsDeathTest : public DeathTestImpl { - public: - WindowsDeathTest(const char* a_statement, Matcher<const std::string&> matcher, - const char* file, int line) - : DeathTestImpl(a_statement, std::move(matcher)), - file_(file), - line_(line) {} - - // All of these virtual functions are inherited from DeathTest. - virtual int Wait(); - virtual TestRole AssumeRole(); - - private: - // The name of the file in which the death test is located. - const char* const file_; - // The line number on which the death test is located. - const int line_; - // Handle to the write end of the pipe to the child process. - AutoHandle write_handle_; - // Child process handle. - AutoHandle child_handle_; - // Event the child process uses to signal the parent that it has - // acquired the handle to the write end of the pipe.
