25.2; shell-mode over TRAMP does not read remote history file as comint input ring |
|

* Bug description:
When using "M-x shell" on a remote file (say "/scp:yf@val17:"), a bash
is started at the server "val17" as the user "yf". But the "*shell*"
buffer is started with an empty input ring. It does not read bash
history file ("/scp:yf@val17:~/.bash_history") into comint input ring.
* What is expected:
When using "M-x shell" on a remote file (say "/scp:yf@val17:"), a bash
is started at the server "val17" as the user "yf". The "*shell*"
1. has the content of "/scp:yf@val17:~/.bash_history" as comint input
ring. And I can use "M-p" to insert previous command, use "M-r" to
isearch previous comamnd, etc.
2. the commands I have input in this "*shell*" will be appended to
"/scp:yf@val17:~/.bash_history" after shell exit.
Just like what "shell-mode" does for local shell.
* To re-produce:
Here is the content of the dribble file of my re-producing this issue
(control characters are replaced with caret)
--8<---------------cut here---------------start------------->8---
^X^F/scp:yf@val17:
^[xshell
^[p^[p^[p^X^Cyes
--8<---------------cut here---------------end--------------->8---
* My findings, if I may:
The code of shell-mode shows
--8<---------------cut here---------------start------------->8---
(setq comint-input-ring-file-name
(or (getenv "HISTFILE")
(cond ((string-equal shell "bash") "~/.bash_history")
((string-equal shell "ksh") "~/.sh_history")
(t "~/.history"))))
--8<---------------cut here---------------end--------------->8---
It seems remote file path is not considered.
* How big this issue is?
Have a shell history is convenient and saves a lot of typing repeated or
similar commands. Me and many of my colleagues use shell history
isearch heavily. It works very well for local shells. It is a little
bit disappointing that it does not work on remote shells.
