Third assignment for 2020 OS course, SSE, Tongji Univ
- GNU/Linux 5.7.0 (Arch Linux)
- python 3.8.3
- pip 20.0.2
- libfuse 3.9.2
Important: This program is only fully compatible with GNU/Linux, before all else, you should make sure that libfuse has been appropriately installed and configured, situation and method could very from distro to distro. And you can also build it from source which can be found here. All the central goals are:
- usable lib binaries at correct places
- successfully loaded kernel module
- deliberately and appropriately configured filesystem permissions
- on-demand config files
(Optional) Enable python virtual environment
python -m venv .venv
. .venv/bin/activateInstall dependencies
pip install -r requirements.txtInitialize your directories manually then mount TinyFS
python src/tinyfs.py [from_source] [to_target]You can also check your mountpoint with mount and grep and logging is enabled at INFO level by default.
Then you can use this TinyFS with your coreutils or graphic/cli file managers.
To implement a new file system, a handler program linked to the supplied libfuse library needs to be written. The main purpose of this program is to specify how the file system is to respond to read/write/stat requests. The program is also used to mount the new file system. At the time the file system is mounted, the handler is registered with the kernel. If a user now issues read/write/stat requests for this newly mounted file system, the kernel forwards these IO-requests to the handler and then sends the handler's response back to the user.
