xfsdump does not currently handle Ctrl-D well during a dialog
prompt. If some text is entered followed by Ctrl-D, an assert
will trip because xfsdump expects a new-line character at the
end of the user's input (or if asserts are disabled, the last
character the user entered will be dropped).
If Ctrl-D is entered without entering any response, some dialog
callers (e.g., tree_subtree_inter()) will abort because they
receive an unexpected response code.
This patch changes xfsdump to treat Ctrl-D as if the user hit
enter. User input (if any) will be passed back to the caller,
and a new line will be echoed to the terminal.
Shouldn't Ctrl+D cause us to ignore the input that was added
before? That's what I would expect from command line applications.
Ctrl-C will behave the way you describe.
I tried a some interactive programs (parted, python, sftp, bash,
xfs_db), and Ctrl-D seems to be ignored if there's already some input.
I'll rework the patch to behave this way unless I hear back from
you.
Thanks,
Bill
