Re: [coLinux-users] [coLinux-devel] [about cofs rename bug]

[Paolo M. <pao...@gm...>]

Hi,
I was trying to understand the problem related to rename on cofs (and
check if the patch was OK for me).
To do it I write a simple script to run on cofs.
This is the script (I call it test.sh)

dd if=/dev/zero of=CCCC count=5 2>/dev/null
mv CCCC DDDD
cont=1
while [ $cont = 1 ]
do
   stat DDDD 2>&1 > /dev/null
   if [ $? != 0 ]; then
       echo -n ERROR
   else
       echo OK
       cont=0
   fi
done

If I run it, it does not show me the problem related to rename on cofs.
On my PC I don't see the problem. This is my output.

root@darkstar:/win/d# ./test.sh
OK
root@darkstar:/win/d# ./test.sh
OK
root@darkstar:/win/d# ./test.sh
OK
root@darkstar:/win/d# ./test.sh
OK
root@darkstar:/win/d# ./test.sh
OK
root@darkstar:/win/d# ./test.sh
OK
root@darkstar:/win/d# ./test.sh
OK
root@darkstar:/win/d# ./test.sh
OK

*But I see an other problem*

If I run it several times and I relanch it ***quickly*** after
termination I see these message, that sometimes show an error.
This error, if I understand correctly, is different from the #2176188.

root@darkstar:/win/d# ./test.sh
mv: `CCCC' and `DDDD' are the same file
OK
root@darkstar:/win/d# ./test.sh
OK
root@darkstar:/win/d# ./test.sh
mv: `CCCC' and `DDDD' are the same file
OK
root@darkstar:/win/d# ./test.sh
mv: `CCCC' and `DDDD' are the same file
OK
root@darkstar:/win/d# ./test.sh
OK
root@darkstar:/win/d# ./test.sh
mv: `CCCC' and `DDDD' are the same file
OK
root@darkstar:/win/d# ./test.sh
OK
root@darkstar:/win/d# ./test.sh
mv: `CCCC' and `DDDD' are the same file
OK

I use 0.7.3.
