FUSE bindings for Go

GO-FUSE: native bindings for the FUSE kernel module. HIGHLIGHTS * High speed: as fast as libfuse using the gc compiler for single threaded loads. * Supports in-process mounting of different FileSystems onto subdirectories of the FUSE mount. * Supports 3 interfaces for writing filesystems: - PathFileSystem: define filesystems in terms path names. - NodeFileSystem: define filesystems in terms of inodes. - RawFileSystem: define filesystems in terms of FUSE's raw wire protocol. * Both NodeFileSystem and PathFileSystem support manipulation of true hardlinks. * Includes two fleshed out examples, zipfs and unionfs. EXAMPLES * examples/hello/hello.go contains a 60-line "hello world" filesystem * zipfs/zipfs.go contains a small and simple read-only filesystem for zip and tar files. The corresponding command is in example/zipfs/ For example, mkdir /tmp/mountpoint example/zipfs/zipfs /tmp/mountpoint file.zip & ls /tmp/mountpoint fusermount -u /tmp/mountpoint * zipfs/multizipfs.go shows how to use in-process mounts to combine multiple Go-FUSE filesystems into a larger filesystem. * fuse/loopback.go mounts another piece of the filesystem. Functionally, it is similar to a symlink. A binary to run is in example/loopback/ . For example mkdir /tmp/mountpoint example/loopback/loopback -debug /tmp/mountpoint /some/other/directory & ls /tmp/mountpoint fusermount -u /tmp/mountpoint * unionfs/unionfs.go: implements a union mount using 1 R/W branch, and multiple R/O branches. mkdir -p /tmp/mountpoint /tmp/writable example/unionfs/unionfs /tmp/mountpoint /tmp/writable /usr & ls /tmp/mountpoint ls -l /tmp/mountpoint/bin/vi rm /tmp/mountpoint/bin/vi ls -l /tmp/mountpoint/bin/vi cat /tmp/writable/*DELETION*/* * union/autounionfs.go: creates UnionFs mounts automatically based on existence of READONLY symlinks. Tested on: - x86 32bits (Fedora 14). - x86 64bits (Ubuntu Lucid). BENCHMARKS We use threaded stats over a read-only filesystem for benchmarking. Automated code is under benchmark/ directory. A simple C version of the same FS gives a FUSE baseline Data points (Go-FUSE version May 2012), 1000 files, high level interface, all kernel caching turned off, median stat time: platform libfuse Go-FUSE difference (%) Lenovo T60/Fedora16 (1cpu) 349us 355us 2% slower Lenovo T400/Lucid (1cpu) 138us 140us 5% slower Dell T3500/Lucid (1cpu) 72us 76us 5% slower On T60, for each file we have - Client side latency is 360us - 106us of this is server side latency (4.5x lookup 23us, 1x getattr 4us) - 16.5us is due to latency measurements. - 3us is due to garbage collection. CREDITS * Inspired by Taru Karttunen's package, https://bitbucket.org/taruti/go-extra. * Originally based on Ivan Krasin's https://github.com/krasin/go-fuse-zip BUGS Yes, probably. Report them through https://github.com/hanwen/go-fuse/issues KNOWN PROBLEMS Grep source code for TODO. Major topics: * Support for MacOS and FreeBSD. * Support for umask in Create * Missing support for network FS file locking: FUSE_GETLK, FUSE_SETLK, FUSE_SETLKW * Missing support for FUSE_INTERRUPT, CUSE, BMAP, POLL, IOCTL * In the path API, renames are racy; See also: http://sourceforge.net/mailarchive/message.php?msg_id=27550667 Don't use the path API if you care about correctness.
