2008-08-16: Released 0.6.0 version!

See the notes and changes here.

2008-06-04: Released 0.5.2 version!

This release was essentially a maintenance release. The changes were: (1) The license was upgraded to GNU GPLv3; (2) The Brute Force search was improved and now accepts any number of input files; (3) There was fixed an incompatibility (compilation error) with GCC-4.3 (thanks to Nacho B. Arias and Martin Michlmayr).

2007-03-28: Released 0.5.1 version!

This release fixes a bug (uninitialized variable) and changes the default behavior of GAFFitter, which now extracts the volumes as much as possible (unlimited iterations).

Note: For those who have used GAFFitter in scripts be aware that this change in the default behavior can produce unexpected results if you don't update your script. To reproduce the older behavior you have to do something like gaffitter -i 1 ...

Official packages of GAFFitter are now available from the main section of Debian unstable. Thanks to the noteworthy work of Nacho Barrientos Arias.

If you are running Debian Sid, simply type (as root): apt-get install gaffitter

2006-08-28: Released 0.5.0 version!

Enjoy!

2006-07-28: Released 0.4.1 version!

This new version adds the ability to sort the output (by name or size, ascending/descending) and fixes some minor bugs. There were also minor improvements, code cleanup and cosmetic changes.

Highlights:

• sort by name (default) or size (-s, --sort-by-size), ascending (default) or descending (-r, --sort-reverse).

Bug fixes:

• fixed complain when using -m option.

Other changes:

• code cleanup, fixed some formating errors, and more.

2006-01-01: Released 0.4.0 version!

This version implements a direct input mode, allowing the user to enter 'size identifier' pairs directly instead of file/dir names. Two new genetic operators were introduced, resulting in an expressive genetic algorithm improvement. There were also some minor changes and bug fixes.

Highlights:

• direct input mode: flexibility and new application areas.
• significant GA efficiency improvement via two new genetic operators, named directed mutation and local optimizer.

Minor changes:

• -t (--target) option is now mandatory (no more default value).
• added -b, -k, -m and -g short options for --bytes, --kb, --mb and --gb, respectively.
• added --si and --di-si (for direct input) options: SI unit, i.e., powers of 1000 instead of 1024.

Bug fixes:

• fixed a bug when trying to read some directories.

The gaffitter 0.4.0 source code can be downloaded here.

2005-12-22: Released 0.3.0 version!

The du (diskusage) tool was replaced by a native code, but a POSIX-compatible environment is still required to get the size of a file or directory.

Highlights:

• The du (from coreutils package) is no longer needed:
  • cleaner and more elegant code: no file descriptors artefact
  • slightly faster: no external calls
  • more flexibility and accuracy
  • no coreutils requirement

• GA enhancements and some performance increase
• Other minor/cosmetic changes

The gaffitter 0.3.0 source code can be downloaded here.

Installation prerequisites:

• POSIX-compatible Operating System (for <sys/stat.h>, <dirent.h> and <unistd.h> headers)

2005-12-16: Released 0.2.0 version!

This version does not require GALib. The gaffitter 0.2.0 source code can be downloaded here.

Highlights:

• entirely new Genetic Algorithm code
• added Brute Force and Best First (First Fit) search
• code cleanup, tuning and minor/cosmetic changes

Installation prerequisites:

• POSIX-compatible Operating System (required 'du' from coreutils package)

2005-11-11: The GALib is no longer required! :)

The GALib has been replaced by an entirely new GA optimizer (internal). CVS version only. Advantages:

• better customization and flexibility = better performance
• no external dependencies
• smaller executable size
• better integration

2005-09-29: Released gaffitter version 0.1.0

This version requires GALib. gaffitter 0.1.0 (and GALib) can be downloaded here.
