make branch for CPAN 0.07_2
1 Fuse version 0.06
2 =================
3
4 Fuse is combination of Linux kernel module and user space library which
5 enables you to write user-space filesystems. This module enables you to
6 write filesystems using perl.
7
8 Additional file-systems using Fuse module are released on CPAN using Fuse::
9 namespace. Currently that includes only Fuse::DBI which allows you to mount
10 database as file system, but there will be more.
11
12 This is a pre-production release. It seems to work quite well. In fact, I
13 can't find any problems with it whatsoever. If you do, I want to know.

16 INSTALLATION
17
18 To install this module type the standard commands as root:
19
20 perl Makefile.PL
21 make
22 make test
23 make install
24
25
26 DEPENDENCIES
27
28 This module requires the FUSE C library and the FUSE kernel module.
29 See http://fuse.sourceforge.net/
30
31 If you intend to use FUSE in threaded mode, you need a version of Perl which
32 has been compiled with USE_ITHREADS. Then, you need to use threads and
33 threads::shared.

36 COPYRIGHT AND LICENCE
37
38 This is contributed to the FUSE project by Mark Glines <mark@glines.org>,
39 and is therefore subject to the same license and copyright as FUSE itself.
40 Please see the AUTHORS and COPYING files from the FUSE distribution for
41 more information.

44 EXAMPLES
45
46 There are a few example scripts. You can find them in the examples/
47 subdirectory. These are:
48
49 * example.pl, a simple "Hello world" type of script
50
51 * loopback.pl, a filesystem loopback-device. like fusexmp from
52 the main FUSE dist, it simply recurses file operations
53 into the real filesystem. Unlike fusexmp, it only
54 re-shares files under the /tmp/test directory.
55
56 * rmount.pl, an NFS-workalike which tunnels through SSH. It requires
57 an account on some ssh server (obviously), with public-key
58 authentication enabled. (if you have to type in a password,
59 you don't have this. man ssh_keygen.). Copy rmount_remote.pl
60 to your home directory on the remote machine, and create a
61 subdir somewhere, and then run it like:
62 ./rmount.pl host /remote/dir /local/dir
63
64 * rmount_remote.pl, a ripoff of loopback.pl meant to be used as a backend
65 for rmount.pl.
66
67
68 BUGS
69
70 At time of writing, Perl (5.8.7) did not support shared subroutine references.
71 Symptoms include a cryptic error message like "Invalid value for shared scalar"
72 from Fuse.pm. Until this is fixed, if you use threaded mode, you need to use
73 symbolic references (i.e. passing "main::cb" instead of \&cb). This doesn't
74 allow things like closures, lexical subs and that sort of thing, but it does
75 work for me.
76
77 The current test framework seems to work well, but the underlying mount/
78 unmount infrastructure is a crock. I am not pleased with that code.
79
80 While most things work, I do still have a TODO list:
81 * "du -sb" reports a couple orders of magnitude too large a size.
82 * need to sort out cleaner mount semantics for the test framework
83 * figure out how to un-linuxcentrify the statfs tests
84 * test everything on other architectures and OS's
