fuse4js's Introduction

Fuse4js

Fuse4js provides Javascript bindings to the FUSE subsystem of Linux. It enables you to develop user-space file systems with node.js.

Requirements

Linux:

Fuse4js has been tested on Ubuntu 10.04, Ubuntu 12.04 and CentOS 5.x (all 32-bit).
GNU Compiler toolchain, including gcc and g++
- On Ubuntu: sudo apt-get install g++
FUSE library and header files.
- On Ubuntu: sudo apt-get install libfuse-dev
- On CentOS / RedHat: yum install fuse-devel
pkg-config tool (typically included out-of-the-box with the OS)
node.js 0.8.7 or later

OSX:

install osxfuse

Tutorial

This tutorial explains how to install and use fuse4js.

Ensure your system meets the software requirements listed above.
Create a /tmp/tutorial directory.
cd to the directory you created.
Create a mnt/ subdirectory. It will be used as the mount point for testing FUSE file systems.
Download the fuse4js/ source directory: git clone git://github.com/vmware/fuse4js.git
Compile the source code to create the fuse4js add-on in a local node_modules/ subdirectory:
npm install fuse4js
Run the sample jsonFS file system:
node fuse4js/example/jsonFS.js fuse4js/example/sample.json /tmp/tutorial/mnt
This mounts the JSON file as a file system. In a another shell, you can browse and make changes to the file system under /tmp/tutorial/mnt. You can view, edit, create, and move files and directories.
To dismount, make sure no processes remain under the file system path, and then type: fusermount -u /tmp/tutorial/mnt
Changes to the file system are discarded. If you want to save the modified data to a new JSON file, add the -o outputJsonFilePath option when starting the program.

Once you are comfortable with the sample program, you can move on to the second example, mirrorFS.js. It is equivalent to the fusexmp.c sample program that ships with the FUSE source code. As its name indicates, it maps an existing file system subtree to a mount point of your choice. It demonstrates more advanced features such as file handles. The syntax is: node fuse4js/example/mirrorFS.js <file_system_directory> <new_mount_point>

Global installation

The tutorial used a local installation of fuse4js that is private to the /tmp/tutorial directory. To install fuse4js globally on your system:

Log in as root, or use sudo
Download the source code into a fuse4js/ subdirectory
Install by typing: npm install -g --unsafe-perm fuse4js
The --unsafe-perm option seems to be necessary to work around an interference between the node-gyp compilation process and npm's downgrading of permissions when running a package's installation script (you may get an EACCES error without it)
At this point, the add-on should be installed under /usr/local/lib/node_modules. To use it in your programs using a statement such as fuse4js = require("fuse4js"), include /usr/local/lib/node_modules in your NODE_PATH environment variable. By default, node.js doesn't look in there for some reason, despite the fact that npm uses that directory as the default global installation location. Example: export NODE_PATH=/usr/local/lib/node_modules

Installation from NPM registry

As of September 17, 2012, fuse4js has been added to the NPM registry, so you can skip the git download step and install it directly by typing:
npm install fuse4js
This will put the module under a local node_modules/ subdirectory.

API Documentation

Fuse4js currently implements a subset of all FUSE file operations. More will be added over time, but the initial set is sufficient to implement a basic read/write file system.

You implement a file system by registering Javascript handler functions with fuse4js. Each handler handles a particular FUSE operation. While the arguments passed to a handler vary depending on the requested operation, the last argument is always a callback function that you invoke when you are finished servicing the request. The arguments to the callback typically include an error code, followed by zero or more additional arguments depending on the FUSE operation. Following FUSE conventions, the error code is set to a negated 'errno' value to indicate error, and zero or a positive value (for read/write operations) to indicate success.

We currently don't have a separate document describing the Javascript interface corresponding to each FUSE operation. Instead, the API is documented in the comments for each handler in the mirrorFS.js sample program, so use that as the reference for now.

How it Works

The FUSE event loop runs in its own thread, and communicates with the node.js main thread using an RPC mechanism based on a libuv async object and a semaphore. There are a couple of context switches per FUSE system call. Read/Write operations also involve a copy operation via a node.js Buffer object.

ToDo List

Automated tests
Support for more FUSE operations, such as hard link management.
Improve performance (try to reduce context switches and copy operations)

fuse4js's Issues

chmod() doesn't pass a callback function?

I'm getting strange behavior when trying to implement the chmod() function. It only gets passed 2 arguments it seems, the path and mode. But the callback function (expected as 3rd argument) is not there! See log:

  s3fs GETATTR: path='/' key='/' +3s
  s3fs GETATTR: path='/cron.sh' key='/cron.sh' +1ms
  s3fs GETATTR: path='/cron.sh' key='/cron.sh' +66ms
{ '0': '/cron.sh', '1': 33261 }
  s3fs CHMOD: path='/cron.sh' mode=33261 +61ms
chmod() does not pass a cb() function... wtf

Where the code looks something like this (basically a no-op, just with some logging):

function chmod(path, mode, cb) {
  console.error(arguments);
  debug('CHMOD: path=%o mode=%o', path, mode);

  if (cb)
    return cb(0);
  else
    console.error('chmod() does not pass a cb() function... wtf');
}

Any idea what's going on here? Thanks in advance.

Running jsonFS doesn't work on ubuntu 12.04 LTS x86-64

This is my dev environment. Looks like the setxattr/statfs changes caused this, since it works if I revert back to commit 65395cb.

Here's the output:

ubuntu@ip-10-171-45-167:/tmp/tutorial$ node fuse4js/example/jsonFS.js fuse4js/example/sample.json /tmp/tutorial/mnt

Input file: fuse4js/example/sample.json
Mount point: /tmp/tutorial/mnt
File system stopped

Mounting external Webdav source.

Hi,

In your documentation, can you give as some examples for common uses like "Mounting external WebDAV server", and/or "Mounting external storage (e.g. Google drive, DropBox, UbuntuOne, Amazon S3, etc) and/or even better "Building a Unified Web Storage filesystem using fuse4js".

Thank you in advance. (I'm traditional [mounts only by root] guy. First time mouting from within application. Hope you understand). Thank you.

Tarballs are not on the NPM repository

Hi,

The last version on the NPM repository is [email protected], but the tarballs of the versions 0.1.5, 0.1.6 and 0.1.7 are not available (404): e.g. https://registry.npmjs.org/fuse4js/-/fuse4js-0.1.9.tgz

It looks to be a known issue: https://github.com/isaacs/npm/issues/4205

Thank you,
Vincent

unmount support

Great job on this module!

Is there anyway to programmatically unmount a fuse4js filesystem after I have called start?

Not compiling on most recent Node.JS

Hi,

I have tried compiling on v0.11.13 and would not compile due to errors.

I then tried v0.8.7 which compiled fine without warnings.

I then tried v0.10.29 which compiled and worked with warnings.
Now using node v0.10.29

Error while using v0.11.13

But I already installed osxfuse 2.7.2 first, but seem it cannot identity?
Not sure is this fail because osx 10.10 or other reason.
Any advice? Thanks

publish latest stable changes

I just noticed that latest published version is more than 3 month old and my code already depends on readlink support. Could you please bump version & publish?

fuse_get_context()

I have a personal preference because of familiarity for nodejs, but the fuse binding seems to be missing one critical function: fuse_get_context(). I can't find it anywhere in the binding.

This is what the python binding has:

https://code.google.com/p/fusepy/source/browse/trunk/context.py

uid, gid, pid = fuse_get_context()

I really need this feature, but I would not want to move the entire project to Python just for this one missing function. Is there a reason why it could be added? That would spare me from trying to do it by myself ;-)

Issue with large file sizes

I have a virtual file that is 3,472,655,443 bytes long and I set the stat.size to this length in the getattr handler. I believe it is in a javascript Number object which should be able to handle up to 53 bit numbers or 9,007,199,254,740,992.

The operating system (Ubuntu Server 14.04) is reporting a file size of 18,446,744,072,887,239,763 when doing a 'ls -l' on the directory holding the file.

I also have this directory shared to windows (over samba) which reports the file size as -822,311,853 bytes.

There is something weird going on here that smells a lot like the number being marshaled into too small of a container in the fuse4js code.

Dual Licensing

Could you consider dual licensing with BSD so that the GPL does not come into play on OSX. As it stands, any software requiring the lib will otherwise require it to licensed under the GPL. In contrast to linux, OSXFuse is under BSD Terms. Alternatively licensing under the LGPL might be an appropriate balance of both which would could also resolve its use in particular circumstances.

Can only process one concurrent operation at a time

FUSE supports concurrent operations, but these bindings do not. If one of the operation handlers waits to call its callback, further operations are blocked until it does.

Async direct-io support

Linux recently landed async direct io support in fuse, would be good to see Node being able to leverage that & do some async pipelining in fuse4js.

Feature: consider GNU LGPL

Hi,

I'm not sure if this is possible but libfuse is actually LGPL. Only the kernel module and accessories are GPL. I am hoping this will allow fuse4js to have a LGPL allowing more opensource software to use it in their projects where they foresee the end customer not wanting to give away their source.

Under what license is FUSE released?
The kernel part is released under the GNU GPL.
Libfuse is released under the GNU LGPL.
All other parts (examples, fusermount, etc) are released under the GNU GPL.

is it possible to change filename on create or release?

Hi, I'm trying to change a file's extension when I create it in the mounted file system. Is this possible? If so, how should I go about doing this? I tried tweaking the create and release functions on the mirrorFS example to rename the file, but no luck. I got an endless loop between create and release when I modified the create command, and I got -43 errors when I modified the release command.

Any direction would be much appreciated. Thank you!

Compilation fails.

Hey. I've been trying to install fuse4js, however the command sudo npm install -g --unsafe-perm fuse4js results in these errors: http://pbin.in/Ze

npm version: 2.7.0

Had to add statfs handler to mirrorFS example

I am running OSX v10.9.2 and the jsonFS example ran fine but the mirrorFS example was not. Using the --unsafe-perm option did not help.

Copying and pasting the statfs handler from jsonFS into mirrorFS seemed to fix it. I don't understand enough of the internals at this point to know why.

Here is the original mirrorFS debug output:

Intercepting inotify watches

I'm working on a compiling proxy file system for frontend assets. The typical workflow for frontend developers involves setting up file watchers to trigger live reloading of browsers when contents of files are updated.

Watches work correctly against the fuse mount, but I have no way to intercept the setup or teardown of these watchers. In the ideal case I'd like to completely intercept the watch call, set up my own watcher against the source directory and trigger the fuse file watcher callback when needed. I would hope that I could cut the amount of inotify watchers in half that way. Also I would prefer to set up watchers on demand, given the actual usage pattern, instead of needing the developer to manually preconfigure what the fuse proxy will need to set up watchers for.

What do I need to do in order to intercept these watcher interactions with my fuse mount? I assume there might be some native bindings that have to be written, and I am willing to give that a go, but I am not even aware of what methods I would need to implement
