Squashfs 3.3

Contributor : Delly A

Changelog for Squashfs 3.3 :

1. Filesystem improvements:

1.1. Maximum block size has been increased to 1Mbyte, and the
default block size has been increased to 128 Kbytes.
This improves compression.

1.2. Sparse files are now supported.  Sparse files are files
which have large areas of unallocated data commonly called
holes.  These files are now detected by Squashfs and stored
more efficiently.  This improves compression and read
performance for sparse files.

2. Mksquashfs improvements:

2.1.  Exclude files have been extended to use wildcard pattern
matching and regular expressions.  Support has also been
added for non-anchored excludes, which means it is
now possible to specify excludes which match anywhere
in the filesystem (i.e. leaf files), rather than always
having to specify exclude files starting from the root
directory (anchored excludes).

2.2.  Recovery files are now created when appending to existing
Squashfs filesystems.  This allows the original filesystem
to be recovered if Mksquashfs aborts unexpectedly
(i.e. power failure).

3. Unsquashfs improvements:

3.1. Multiple extract files can now be specified on the
command line, and the files/directories to be extracted can
now also be given in a file.

3.2. Extract files have been extended to use wildcard pattern
matching and regular expressions.

3.3. Filename printing has been enhanced and Unquashfs can
now display filenames with file attributes
(’ls -l’ style output).

3.4. A -stat option has been added which displays the filesystem
superblock information.

3.5. Unsquashfs now supports 1.x filesystems.

4. Miscellaneous improvements/bug fixes:

4.1. Squashfs kernel code improved to use SetPageError in
squashfs_readpage() if I/O error occurs.

4.2. Fixed Squashfs kernel code bug preventing file
seeking beyond 2GB.

4.3. Mksquashfs now detects file size changes between
first phase directory scan and second phase filesystem create.
It also deals better with file I/O errors.

   Squashfs is a compressed read-only filesystem for Linux. Squashfs is intended for general read-only filesystem use, for archival use (i.e. in cases where a .tar.gz file may be used), and in constrained block device/memory systems (e.g. embedded systems) where low overhead is needed.

   I think squashfs stands for squash file system. Is it different entity from ext-3? And it is implemented in Zencafe and many other distros? Any answers would be appreciated.
