fuse-archive
is a program that serves an archive or compressed file (e.g.
foo.tar
, foo.tar.gz
, foo.xz
or foo.zip
) as a read-only
FUSE file system.
It is similar to mount-zip
and
fuse-zip
but speaks a larger range
of archive or compressed file formats.
It is similar to archivemount
but
can be much faster (see the Performance section below) although it can only
mount read-only, not read-write.
$ git clone https://github.com/google/fuse-archive.git
$ cd fuse-archive
$ make
On a Debian system, you may first need to install some dependencies:
$ sudo apt install libarchive-dev libfuse-dev
Create a single .tar.gz
file that is 256 MiB decompressed and 255 KiB
compressed (the file just contains repeated 0x00 NUL bytes):
$ truncate --size=256M zeroes
$ tar cfz zeroes-256mib.tar.gz zeroes
Create a mnt
directory:
$ mkdir mnt
fuse-archive
timings:
$ time fuse-archive zeroes-256mib.tar.gz mnt
real 0m0.443s
$ dd if=mnt/zeroes of=/dev/null status=progress
524288+0 records in
524288+0 records out
268435456 bytes (268 MB, 256 MiB) copied, 0.836048 s, 321 MB/s
$ fusermount -u mnt
archivemount
timings:
$ time archivemount zeroes-256mib.tar.gz mnt
real 0m0.581s
$ dd if=mnt/zeroes of=/dev/null status=progress
268288512 bytes (268 MB, 256 MiB) copied, 569 s, 471 kB/s
524288+0 records in
524288+0 records out
268435456 bytes (268 MB, 256 MiB) copied, 570.146 s, 471 kB/s
$ fusermount -u mnt
Here, fuse-archive
takes about the same time to scan the archive, bind the
mountpoint and daemonize, but it is ~700× faster (0.83s vs 570s) to copy out
the decompressed contents. This is because fuse-archive
does not use
archivemount
's quadratic complexity
algorithm.
