Subject: [PATCH 2/4] am: read interactive input from stdin
Date: Mon, 20 May 2019 08:09:26 -0400
Message-ID: <> (raw)
In-Reply-To: <>

In the conversion of git-am from shell script to C, we switched to using
git_prompt(). Unlike the original shell command "read reply", this
doesn't read from stdin at all, but rather from /dev/tty.

In most cases this distinction wouldn't matter. We require (as the shell
script did) that stdin is a tty, so they would generally be the same
thing. But one important exception is our test suite: even with
test_terminal, we cannot test "am --interactive" because it insists on
reading from /dev/tty, not the pseudo-tty we've set up in the test

Fixing this clears the way to adding tests in a future patch.

Part of me dies inside when I look at adding the magical "64". But we
expect this input to be single-line (or at most, somebody might actually
type out "edit", etc), and avoiding strbuf_getline() saves us from
having to free the strbuf in the many early return paths. I dunno. If
it's too ugly it would not be too hard to switch it over.
