From: David Keegan <david.keegan <at> shenick.com> To: 6584 <at> debbugs.gnu.org Subject: bug#6584: 23.2; M-p (comint-previous-input) breaks intermittently in telnet-mode. Date: Thu, 08 Jul 2010 08:43:37 +0100
Enter telnet-mode via the rsh command with remote-shell-program set to "ssh" in a situation where ssh keys have been set up for the remote host and therefore there is no password prompt. The telnet-mode code continues trying figure out the type of system it is connected to via telnet-initial-filter for a much longer perioud than normal. Depending on the output from the remote host, the following issues may arise: 1. M-p (comint-previous-input) breaks. Instead of retrieving the previous command to the RHS of the prompt it places it on the LHS of the prompt where it is useless. This is caused by function telnet-check-software-type-initialize which sets comint-prompt-regexp inappropriately to "^[^*>\n]*[*>] *" when it sees "its" in the remote host output. 2. Spurious prompts for a password if "passw" happens to occur in the remote host output.
