Thanks. I took a brief look at adding "real" terminal tests for the credential code using our test-terminal/lib-terminal.sh setup. Unfortunately, it falls short of what we need. test-terminal only handles stdout and stderr streams as fake terminals. We could pretty easily add stdin for input, as it uses fork() to work asynchronously. But the credential code does not actually read from stdin. It opens and reads from /dev/tty explicitly. So I think we'd have to actually fake setting up a controlling terminal. And that means magic with setsid() and ioctl(TIOCSCTTY), which in turn sounds like a portability headache. So it's definitely possible under Linux, and probably under most Unixes. But I'm not sure it's worth the effort, given that review already caught the potential bug here. Another option would be to instrument git_terminal_prompt with a mock-terminal interface (say, reading from a file specified in an environment variable). But I really hate polluting the code with test cruft, and it would not actually be testing an interesting segment of the code, anyway. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
