Current version: 1.1.2

The Most Efficient Gnutella Client

gtk-gnutella is a server/client for Gnutella. It runs on Microsoft Windows and every Unix-like system which supports GTK+ (1.2 or above). The GNOME desktop environment is not required. It is currently developed and tested under Linux (Debian) as well as NetBSD. It is known to run at least on Linux, FreeBSD, NetBSD, Darwin, Solaris, Tru64 UNIX (OSF/1), SGI IRIX, BeOS whereas CPU architectures include x86, AMD64, PowerPC, SPARC, MIPS. And of course Microsoft Windows (XP at least).

gtk-gnutella is free open-source software and released under the GNU General Public License (GPL).

gtk-gnutella is not finished yet, but it is fully functional: you may share, search, and download. And it is stable too, users usually just leave it run unattended for days.

All ideas and comments are welcome to the gtk-gnutella-devel mailing list. Bugs should be reported to the SourceForge.net Bug Tracker

We need additional contributors for C development and documentation

21 March 2015, Version 1.1.2 Released

This is mainly a bug-fixing release, addressing rare crashes that have been happening in production. It also contains several improvements.

It fixes a user-reported bug whreby it was not possible to properly configure the download paths using the GUI -- that led to application crashes due to the incomplete support for discovered threads (which GTK is using underneath to manage the dialog box).

Another bug was caused by the HTTP header parsing logic which did not allow "." in header names. That made it refuse to parse headers sent by some UPnP devices, such as "BOOTID.UPNP.ORG" or "CONFIGID.UPNP.ORG", prevening UPnP mappings from being installed.

Hapening rarely but still annoying, there was a bug on the error handling path of write errors to the TX network stack, leading to assertion failures in the mq_tcp_putq() routine. That was because the qrt_compressed() routine was not handling task cancellation properly. The likelyhood of hitting that bug when running as a leaf node was very low.

On the improvement side, the search list is now highlighting searches for which we have associated downloads by displaying the text in green. Further tweaks were made to our GTK2 code to make sure the changes are reported "real time" when the state changes, which was not always the case before (one needed to go over a search by explicitly clicking on it to update the display in the search list).

The SHA1 computation code was also further optimized to be as fast as possible, reducing file hashing time by two! Since SHA1 hashing happens regularily in gtk-gnutella to collect entropy, optimizing the SHA1 computation affects more than just file verification.

2 July 2014, Version 1.1.0 Released

This is a major release introducing new features and making gtk-gnutella a multi-threaded application with drastic performance boosts for background tasks like file hashing or library rescanning.

Another major feature is the added support for the G2 search protcol: we are connecting to G2 hubs as a leaf, answer to search / browse requests from G2 hosts. We also use G2 to issue our own searches. Finally, we freely exchange files with G2 hosts (downloading and uploading).

The G2 protocol was further extended to make sure G2 query hits convey as much information as Gnutella query hits, in particular for alt-loc propagation and TLS support. The G2 semi-reliable UDP layer is also leveraging the new features designed for the corresponding Gnutella layer (cumulative and extended acknowledgments), gracefully falling back to legacy features if the remote host is not able to understand the new features.

A critical bug was fixed: reception of carefully crafted invalid DHT messages would lead to an immediate crash, an open door for Denial of Service (DoS) attacks. That bug has been present since 0.97 (release of August 2011).

Last but not least, the code base has now been checked by Coverity. There was a very low defect rate of 0.26 (amount of true defects per thousand lines of code) and all problems were fixed.
