Erik Faye-Lund	afb43561b8	mingw: reuse tty-version of git_terminal_prompt The getpass-implementation we use on Windows isn't at all ideal; it works in raw-mode (as opposed to cooked mode), and as a result does not deal correcly with deletion, arrow-keys etc. Instead, use cooked mode to read a line at the time, allowing the C run-time to process the input properly. Since we set files to be opened in binary-mode by default on Windows, introduce a FORCE_TEXT macro that expands to the "t" modifier that forces the terminal to be opened in text-mode so we do not have to deal with CRLF issues.

Erik Faye-Lund	67fe735653	compat/terminal: separate input and output handles On Windows, the terminal cannot be opened in read-write mode, so we need distinct pairs for reading and writing. Since this works fine on other platforms as well, always open them in pairs. Signed-off-by: Erik Faye-Lund <kusmabite@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago
Erik Faye-Lund	9df92e6369	compat/terminal: factor out echo-disabling By moving the echo-disabling code to a separate function, we can implement OS-specific versions of it for non-POSIX platforms.

Jeff King	67ba123fd1	terminal: seek when switching between reading and writing When a stdio stream is opened in update mode (e.g., "w+"), the C standard forbids switching between reading or writing without an intervening positioning function. Many implementations are lenient about this, but Solaris libc will flush the recently-read contents to the output buffer. In this instance, that meant writing the non-echoed password that the user just typed to the terminal. Fix it by inserting a no-op fseek between the read and write. The opposite direction (writing followed by reading) is also disallowed, but our intervening fflush is an acceptable positioning function for that alternative.

Jeff King	21aeafceda	add generic terminal prompt function When we need to prompt the user for input interactively, we want to access their terminal directly. We can't rely on stdio because it may be connected to pipes or files, rather than the terminal. Instead, we use "getpass()", because it abstracts the idea of prompting and reading from the terminal. However, it has some problems: 1. It never echoes the typed characters, which makes it OK for passwords but annoying for other input (like usernames). 2. Some implementations of getpass() have an extremely small input buffer (e.g., Solaris 8 is reported to support only 8 characters). 3. Some implementations of getpass() will fall back to reading from stdin (e.g., glibc). We explicitly don't want this, because our stdin may be connected to a pipe speaking a particular protocol, and reading will disrupt the protocol flow (e.g., the remote-curl helper). 4. Some implementations of getpass() turn off signals, so that hitting "^C" on the terminal does not break out of the password prompt. This can be a mild annoyance. Instead, let's provide an abstract "git_terminal_prompt" function that addresses these concerns. This patch includes an implementation based on /dev/tty, enabled by setting HAVE_DEV_TTY. The fallback is to use getpass() as before. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	13 years ago
