send-email: refactor and ensure prompting doesn't loop forever
Several places in send-email prompt for input, and will do so forever when the input is EOF. This is poor behavior when send-email is run unattended (say from cron). This patch refactors the prompting to an ask() function which takes a prompt, an optional default, and an optional regex to validate the input. The function returns on EOF, or if a default is provided and the user simply types return, or if the input passes the validating regex (which accepts all input by default). The ask() function gives up after 10 tries in case of invalid input. There are four callers of the function: 1) "Who should the emails appear to be from?" which provides a default sender. Previously the user would have to type ctrl-d to accept the default. Now the user can just hit return, or type ctrl-d. 2) "Who should the emails be sent to?". Previously this prompt passed a second argument ("") to $term->readline() which was ignored. I believe the intent was to allow the user to just hit return. Now the user can do so, or type ctrl-d. 3) "Message-ID to be used as In-Reply-To for the first email?". Previously this prompt passed a second argument (effectively undef) to $term->readline() which was ignored. I believe the intent was the same as for (2), to allow the user to just hit return. Now the user can do so, or type ctrl-d. 4) "Send this email?". Previously this prompt would loop forever until it got a valid reply. Now it stops prompting on EOF or a valid reply. In the case where confirm = "inform", it now defaults to "y" on EOF or the user hitting return, otherwise an invalid reply causes send-email to terminate. A followup patch adds tests for the new functionality. Signed-off-by: Jay Soffian <jaysoffian@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
