Hi,
I have a problem while implementing a fuse filesystem in python. for now i just have a proxy filesystem, exactly like a mount --bind would be.
But, any file created, opened, or read on my filesystem is not released (the corresponding FD is not closed)
Here is an example :
yume% ./ProxyFs.py `pwd`/test yume% cd test yume% ls mdr yume% echo test > test yume% ls mdr test yume% ps auxwww | grep python cor 22822 0.0 0.0 43596 4696 ? Ssl 12:57 0:00 python ./ProxyFs.py /home/cor/esl/proxyfs/test cor 22873 0.0 0.0 6352 812 pts/1 S+ 12:58 0:00 grep python yume% ls -l /proc/22822/fd total 0 lrwx------ 1 cor cor 64 2010-05-27 12:58 0 -> /dev/null lrwx------ 1 cor cor 64 2010-05-27 12:58 1 -> /dev/null lrwx------ 1 cor cor 64 2010-05-27 12:58 2 -> /dev/null lrwx------ 1 cor cor 64 2010-05-27 12:58 3 -> /dev/fuse l-wx------ 1 cor cor 64 2010-05-27 12:58 4 -> /home/cor/test/test yume%
Does anyone have a solution to actually really close the fds of the file I use in my fs ?
I'm pretty sure it's a mistake in the implementation of the open, read, write hooks but i'm stucked...
Let me know if you need more details !
Thanks a lot
