bug#24787: 25.1; eshell cd not changing directory on remote path (windows-nt)

[Gary O'Sullivan]

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:


Debugger entered--Lisp error: (error "No such directory found via
CDPATH environment variable")

  signal(error ("No such directory found via CDPATH environment variable"))

  funcall-interactively(eshell-send-input nil)

  call-interactively(eshell-send-input nil nil)

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"
