Subject: 25.1; eshell cd not changing directory on remote path (windows-nt)

On Windows I can change remote directories in eshell via absolute paths

but using relative paths return an error message "No such directory

found via CDPATH environment variable".


Run runemacs.exe -Q

M-x eshell

Welcome to the Emacs shell


c:/software/emacs/bin $ cd /plink:mysrv:/

/plink:mysrv:/home/gary/ $ cd etc

No such directory found via CDPATH environment variable

/plink:mysrv:/home/gary/ $ cd /plink:mysrv:/etc

/plink:mysrv:/etc $


If I M-x toggle-debug-on-error I get the following backtrace:

I get the same error message if I try the following from the *scratch*

buffer:


(cd "/plink:mysrv:/") ; --> "/plink:mysrv:/"

(cd "etc") ; --> (error "No such directory found via CDPATH
environment variable")

(getenv "CDPATH") ; --> nil


If I change the error message in the cd function (files.el) to look like

the following


(error "No such directory '%s' found via CDPATH environment variable
'%s'" dir cd-path)


then it returns


No such directory ’etc’ found via CDPATH environment variable ’(./)’"


expand-file-name returns a path beginning with "c:" if the second arg

is "./" .


default-directory ; --> "/plink:mysrv:/"

(expand-file-name "etc") ; --> "/plink:mysrv:/etc"

(expand-file-name "etc" default-directory) ; --> "/plink:mysrv:/etc"

(expand-file-name "etc" "./") ; --> "c:/plink:mysrv:/etc"

Wouldn't the corresponding relative path for this be ../../etc? (I'm
assuming cd /plink:mysrv:/home/gary/etc doesn't work)

The output from the ls command looks ok, I can see the etc directory but 
pwd/cd seems to be confused. If I go directly to 
"/plink:mysrv:/home/gary" I can list the files in my home directory but 
cd is still not working.

c:/software/emacs/bin $ cd /plink:mysrv:/
/plink:mysrv:/home/gary/ $ pwd
/plink:mysrv:/home/gary/
/plink:mysrv:/home/gary/ $ ls
bin   dev  home  lib64       media  mnt  opt   root  selinux  sys usr
boot  etc  lib   lost+found  misc   net  proc  sbin  srv      tmp var
/plink:mysrv:/home/gary/ $ cd etc
No such directory found via CDPATH environment variable
/plink:mysrv:/home/gary/ $ cd /plink:mysrv:/home/gary
/plink:mysrv:/home/gary $ pwd
/plink:mysrv:/home/gary
/plink:mysrv:/home/gary $ ls

I can confirm I see this on my work’s Windows 10 PC using Emacs 25.1.
