bash_completion doesn't know how to complete directories on a vboxsf mount

[Yann]

Hi,

I tend to believe it's a vboxsf defect, but I don't have any proof... I marked this ticket at 'minor', but it's rather annoying.

The problem is that directories under vboxsf mount autocompletes with a space instead of a '/' for certain commands (rm, ls)

and with nothing for cd (instead of '/' again)

Here is what I see:

yann@dev:~/dev$ mkdir -p /tmp/xxx/yyy/zzz
yann@dev:~/dev$ mkdir -p xxx/yyy/zzz
yann@dev:~/dev$ set -x
yann@dev:~/dev$ ls /tmp/xxx/y+ local cur opt
++ _get_cword
++ [[ 10 -eq 0 ]]
++ [[ 13 == \13 ]]
++ echo /tmp/xxx/y
+ cur=/tmp/xxx/y
+ [[ /tmp/xxx/y == --*=* ]]
+ [[ /tmp/xxx/y == -* ]]
+ [[ ls == @(mk|rm)dir ]]
+ _filedir
+ local 'IFS=   
' xspec
+ _expand
+ [[ /tmp/xxx/y == \~*/* ]]
+ [[ /tmp/xxx/y == \~* ]]
+ toks=()
+ local toks tmp
+ read -r tmp
+++ quote_readline /tmp/xxx/y
+++ local t=/tmp/xxx/y
+++ echo ''\''/tmp/xxx/y'\'''
++ compgen -d -- ''\''/tmp/xxx/y'\'''
+ [[ -n /tmp/xxx/yyy ]]
+ toks[${#toks[@]}]=/tmp/xxx/yyy
+ read -r tmp
+ [[ '' != -d ]]
+ xspec=
+ read -r tmp
+++ quote_readline /tmp/xxx/y
+++ local t=/tmp/xxx/y
+++ echo ''\''/tmp/xxx/y'\'''
++ compgen -f -X '' -- ''\''/tmp/xxx/y'\'''
+ [[ -n /tmp/xxx/yyy ]]
+ toks[${#toks[@]}]=/tmp/xxx/yyy
+ read -r tmp
+ COMPREPLY=("${COMPREPLY[@]}" "${toks[@]}")

yann@dev:~/dev$ ls xxx/y+ local cur opt
++ _get_cword
++ [[ 5 -eq 0 ]]
++ [[ 8 == \8 ]]
++ echo xxx/y
+ cur=xxx/y
+ [[ xxx/y == --*=* ]]
+ [[ xxx/y == -* ]]
+ [[ ls == @(mk|rm)dir ]]
+ _filedir
+ local 'IFS=

+ _expand
+ [[ xxx/y == \~*/* ]]
+ [[ xxx/y == \~* ]]
+ toks=()
+ local toks tmp
+ read -r tmp
+++ quote_readline xxx/y
+++ local t=xxx/y
+++ echo ''\''xxx/y'\'''
++ compgen -d -- ''\''xxx/y'\'''

HTH, let me know if you need more details

So far we were not able to reproduce this problem. I tested this with a Linux host + a Linux guest. Please could you attach a VBox.log file of such a VM session?

[Yann]

I've attached the file per your request, please note that this is not consistent on my installation either, but is still fairly easy to reproduce (i.e it bugs be on a regular basis)

Please reopen if still relevant with a recent VirtualBox release.
