6 March 2016, Version 1.1.9 Released

This is mostly a bug-fixing release.

It fixes an important bug in the UPnP discovery path that led to a crash when it found more than one UPnP device on the network.

It also introduces a new Glossary that can be displayed to explain some terms that may be hard to understand for newcomers, so that they may in turn benefit from the tooltips and the information in the FAQ.

On Windows, one important change is that we now force all memory allocations from the external DLLs to use our own malloc() implementation. This proves that one of the DLLs is exhibiting a memory leak. Plugging that leak will unfortunately require that a garbage collector be implemented. Measurements indicate that 4K leak every second on average, which eventually leads to an out-of-memory crash after a few days (2 to 3), preventing high uptimes on Windows. The leak is not originating from gtk-gnutella's code.

  • [GTK2] Added menu to display the new glossary window.
Bug Fixes
  • Define PTHREAD_STACK_MIN to 0 in case it is not supplied by <pthread.h>.

  • entropy_collect_host(): no longer attempt to get the host IP addresses.
  • file_locate_from_path(): if pathname is qualified, duplicate argument!
  • ftw_foreach(): prevent memory leak on error path.
  • thread_lock_deadlock(): avoid de-referencing NULL if possible.
  • upnp_discovered(): avoid segfault when we have to pick the first device.
Under the Hood

  • Suspend threads created after a global suspension is in effect.
  • Warn when we cannot find a thread to record / release a lock.

18 December 2015, Version 1.1.8 Released

This is an emergency bug-fixing release.

It addresses systematic crashes on some platforms, right at startup time, and prevents random deadlocks on OS/X.

The systematic crash was due to an innocent change, which actually perturbed the order of the initialization routines and, depending on the conditions, caused an assertion failure during one of the thread startup. Curiously, the error manifests randomly and does not seem to depend on the OS but rather on other subtle environment issues: one Linux distribution could be fine whilst another was hit by the bug.

13 December 2015, Version 1.1.7 Released

This release adds support for new features:

  • TLS upgrade of existing connections.
  • Inbound HTTPS connections.
  • Use of a supervisor process to relaunch gtk-gnutella on crashes.

The TLS upgrade allows connections that have started without TLS to negotiate TLS on the fly without having to reconnect. They are flagged as "e" to show that encryption was dynamically added, as opposed to "E" which indicates an initial TLS connection.

Certificates are now automatically generated and this allows HTTPS connections from browsers. For now this is of limited use, but it will come handy in the near future when building a web-enabled GUI.

To be more resilient against crashes, gtk-gnutella now automatically launches a supervisor process that will launch the real gtk-gnutella as a child process and monitor its fate, restarting a new process when the old one failed. This is far more robust than having the process re-exec() itself at crash time since there are some crashing conditions that do not even allow the process to go that far in the crash handling...

On Windows, provided you have installed Cygwin's gdb, crash logs will now contain a gdb backtrace of the failing process, making analysis of what went wrong easier than with a simple stack trace.

Your previous GUID and KUID will be regenerated the next time you restart due to a new algorithm used to detect that a configuration file is not accidentally reused on another machine: the host name is now included, instead of just the physical file information. So when moving a disk to another machine, or simply cloning an existing virtual machine, we are no longer going to reuse these IDs which are supposed to be unique by properly detecting that the information was copied over.

A bug in open_read() caused the Geo IP database to not be loaded on Windows.

Finally, all the options given to gtk-gnutella can now be abbreviated as long as they are not ambiguous (i.e. enough is given to make them non-ambiguous). For instance, given the current set of options, --p would be ambiguous but --s will always mean --shell. However, --pi is not ambiguous and refers to --ping.

  • By default, gtk-gnutella now supervises its children to restart them.
  • Now allows incoming HTTPS connections.
  • Added support for Gnutella connection upgrade to TLS.
  • Added support of RFC-2817 for upgrading to TLS within HTTP/1.1.

8 November 2015, Version 1.1.6 Released

This is a bug-fixing release.

8 October 2015, Version 1.1.5 Released

This is a bug-fixing release.

Most of these bugs were discovered by investigating why gtk-gnutella was frequently crashing on OS/X platforms. Why other platforms were not having the same problems remains a mystery, since all these bugs were not specific to OS/X, apart from the vmm_munmap() bug -- since mmap() is only used on OS/X due to its lack of the sendfile() system call.

One of the fixed bugs could lead to a crash when the network connection was broken (e.g. a cable unplugged or a WiFi connection terminated).

  • UHC: re-engineered the random choice of UHCs in the pre-established list.
Bug Fixes
  • qrt_patch_compress_done(): fixed race with qrp_comp_done().
  • xmalloc: prevent deadlock when freeing deferred blocks on the allocation path.
  • pmap_remove_from(): protect from exceptional corner case to avoid crash.
  • ut_frag_pmsg_free(): don't requeue an unsent message synchronously.
  • VMM: fixed race condition in vmm_munmap() that could lead to failures.
  • omalloc: fixed chunk management when memory alignment is required.
Under the Hood
  • well_state_discard(): fixed missing indexing of array pointer.
  • thread-test: avoid mixed output by using atomic I/Os to stderr for messages.
  • thread-test: main testing entry points now clearly flagged in output.
  • signal_trampoline(): be verbose and lenient when our pre-condition fails.
  • evq_event_discard(): fixed message to log the name of the registering thread.
  • hash_list_lookup(): was mistakenly returning a const value.
  • thread_private_set_extended(): ensure a NULL free routine clears any old one.
  • crash_mode(): removed redundant call to thread_suspend_others().
  • rand31_random_seed(): avoid popcount(), prefer modulo with a prime number.
  • hash_offset_init_once(): avoid entropy_minirand(), causes dealocks on Windows.
  • uhc_send_ping(): if we cannot contact selected UHC, try with another one.
  • omalloc_chunk_*protect(): ensure chunk is consistent with page boundaries.
  • More assertions in omalloc() to ensure we're not corrupting memory.
  • Use global mutex to protect symbols_xxx() calls, simplified stacktrace code.
  • Reduced UHC retry time from 1 hour down to 3 minutes.
  • Revised UHC list.
  • More thread-safe refactoring for other stringification routines.

9 September 2015, Version 1.1.4 Released

This release is mostly a bug-fixing release.

One major bug (leading to crash) was found in the G2 frame parsing layer: a carefully crafted G2 packet sent to GTKG could crash it, leading to a Denial of Service. For that reason, an upgrade to 1.1.4 is strongly recommended.

The only major new feature is the added cleanups of the TTH cache and the crash log directory, to make sure we do not keep useless files on the disk forever.

Because the Phex servent is no longer maintained, there is now a workaround for that particular servent to ensure it can correctly download from GTKG.

  • [GTK2] Added tri-state column sorting in "property editor" preference pane.
  • [GTK2] Show icon + warning message when we have no TCP listening socket.
  • Added an "install-strip" target to all Makefiles to install with stripping.
  • Can no longer edit properties flagged as "internal" through shell or GUI.
  • Added new "session_start_stamp" property to hold the true starting time.
  • Added support for TTH cache cleanup.
  • Added automatic cleanup of the crash log directory.
  • New shell command "random stats" to display the statistics on random layer.
  • Workaround for Phex: always send X-Gnutella-Content-URN in upload replies.
  • Updated GeoIP database.
Bug Fixes
  • upnp_natpmp_discovered(): detect when UPnP layer was shutdown and abort.
  • Fixed bad definition of XXTEA key, which led us to use only its first 4 bytes.
  • node_g2_read(): need to only read 3 bytes usually to determine frame length.
  • thread_sp(): tweaked to defeat gcc 5.x optimization leading to a NULL return.
  • File moving: notify main thread as soon as file is completely copied.
  • update_available_ranges(): lack of X-Available means file is full on server.
Under the Hood
  • Windows: added getppid() and statvfs() emulation, plus rmdir() support.
  • Improved the unpredictability of our random numbers.
  • Loudly warn if attempting a file-descriptor operation on a revoked descriptor.
  • Added compat_sendfile() with fallback to emulated version when necessary.
  • Added compat_statvfs() for portability and code simplification.
  • File moving operations now use sendfile() if available.

  • VMM: raised maximum page cache lifetime from 3 to 15 minutes.
  • page_cache_find_pages(): treat user memory as if under short-term strategy.
  • filepath_basename(): optimize code when G_DIR_SEPARATOR is '/'.
  • Optimized CMP() to avoid branching regardless of the arguments.
  • Added ftw_foreach() to traverse a file system and process each entry.
  • mingw_readdir(): do not change errno if it was left untouched by _wreaddir().
  • Let mingw_{opendir,readdir,closedir} use normal types, not generic ones.
  • mingw_stat(): added workaround for trailing "/" or "/." in paths.
  • etree_traverse_internal(): minor optimization to avoid trailing +1 each time.
  • Added etree_sort() and etree_sort_with_data() to sort children of all nodes.
  • Changed signature of decoding base16 and base32 routines.
  • Regenerated Configure to fix the fdopendir() compile test.
  • Make sure pointer hashing distributes its trailing bits evenly.
  • elist_merge_sort(): don't update tail, just do one single pass at the end.
  • vmm_dump_pmap_log(): copy pmap data, then process dumping without locks.

8 April 2015, Version 1.1.3 Released

This is mainly a critical bug-fixing release, addressing a huge shortcoming in 1.1.2: all Shareaza leaves are incorrectly flagged as being fakes and are being removed quicktly from ultrapeers, creating network churn and instability. Everyone running gtk-gnutella as Ultrapeer must upgrade to 1.1.3 quickly.

Releasing quickly after 1.1.3 is also a pretext for improving stability on Windows platforms, especially after restarts: because Windows does not support the "close on exec" flag on file descriptors, restarted processes were left with several instances of a listening socket bound to the same port, causing havoc as behaviour is totally undefined and was most probably leading to the inability for the process to get any incoming connections.

On Windows, we now also monitor the memory usage more closely, in order to avoid the C runtime from issuing a (blocking) popup signalling a fatal memory allocation error should it run out of space.

More generally, the VMM layer is now capable of trapping fatal memory allocation errors and handling them more efficiently. In particular, when everything has failed, the layer can request a brutal restart of the process. Under less dire circumstances, a graceful restart will be requested.

This was also an occasion to revisit the long-term allocation strategy in the VMM layer and optimize it in order to further limit fragmentation of the VM space. Even though avoiding fragmentation matters mostly for 32-bit applications, this also limits the amount of individual memory region mappings the kernel has to maintain and gtk-gnutella has to keep track of.

Finally, a last-minute bug fix where a user reported a deadlock in the QRP processing code. After investigation, it turned out that there was indeed a recursive locking on a spinlock that had escaped all real-life testing out there so far!

  • [GTK2] Added popup menu icon in front of "force push mode" for sources.
  • [GTK2] Added warning icon in status bar when kernel runs short of net buffers.
  • Increased default node connection timeout and size of the quick connect pool.
  • Updated the shell "status" command to display "!IP" on net buffer shortage.

  • Updated GeoIP databases.
Bug Fixes
  • Fixed invalid test for "fake" Shareaza that led to network instabilities.
  • Made QRP lock a mutex to allow for recursive locking through qrp_comp_done().
Under the Hood
  • On out-of-memory conditions, attempt to auto-restart if possible.
  • Windows: monitor committed memory, crashing before the kernel would kill us.
  • Added crash_restart() and controlling routines to request smooth restart.
  • On network buffer shortage (ENOBUFS), stop TCP connections for a while.
  • UPnP: protect upnp_mapping objects given to callbacks with reference counts.
  • Adjusted lock tracking when locks are disabled, fixing lock swapping.
  • Windows: remember socket descriptors so that we can close them on exec().
  • Refactored code for listening sockets to warn when bound port is already used.
  • When shutdowning in "crash mode", skip most of the memory cleanup.

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.

  • [GTK2] Added translation URL in the "About" GUI dialog.
  • [GTK2] Highlight searches with registered downloads by using green text.
  • [GTK2] Added tri-state column sorting to the "upload history" panel.

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.

Other minor improvements are present, as well as low-level bug fixes.

11 November 2012, Version 0.98.4 Released

This is an important release correcting severe bugs affecting the overall wealth of the system: the PARQ upload queue was not properly restored, the DHT was not always sending correct values back (resulting in failed lookups), and SDBM (our hash-on-disk database) had two well-hidden bugs that could cause crashes at startup or that compromised regular runtime operations.

This release also introduces an interesting improvement: we are now using a reliable UDP layer to transfer out-of-band query hits, ensuring that these important messages are properly sent and received and never lost.

The SPAM-detection on query hits received via UDP was too eager to discard results from perfectly valid sources, causing improper loss of results from your queries.

We were also wrongly sending out more queries than necessary: a long-standing bug caused locally-issued OOB-proxied queries to be re-emitted a second time, and we were re-forwarding duplicate queries (received with higher TTL than before) to all the leaves. Although not harmful, these two bugs were wasting some of the outgoing bandwidth when running as a ultra node.

  • Strip GGEP "NP" key from relayed queries.
  • Use higher-priority UDP messages for important or time-sensitive data.
  • Use semi-reliable UDP to transfer critical data (query hits).
  • Make sure the queries we OOB-proxy have a GGEP "SO" key for secure OOB hits.
  • Ignore unsecure OOB hit promises from hosts known to support secure OOB.
  • Use some of our connected ultra nodes when filling UHC pongs.
  • Updated GeoIP databases.
  • When resuming from crashes, do not stop session-only searches.

11 September 2011, Version 0.97.1 Released

Version 0.97.1 is a bug-fixing release, addressing critical bugs that slipped through in the 0.97 release but which happen only in particular conditions.

The project also switched from SVN to git. This affects the version number which no longer includes a single SVN revision but instead uses the combination of a counter for the number of changes since the last release plus git's abbreviated commit ID. Tagged releases do not contain any build information.

Bug Fixes
  • Fixed bootstrapping problems on IPv6 enabled hosts [bug #3376322].
  • Forgot to clear global HTTP handle on GHC errors [bug #376322].
  • Typo caused crash when processing alternate locations in firewalled mode with PFSP enabled.

  • Use the downloads folder on Windows 7 and Vista for completed downloads.
  • Updated the geographic IP mapping database.
  • Integrated spell check of the French translation from stegozor.
  • Turned zalloc_always_gc to FALSE by default.

18 July 2011, Version 0.97 Released

Version 0.97 is a major release, fixing critical long-standing bugs and introducing handy new features.

New Features
  • Added HTTP request pipelining.
  • Added GUESS (Gnutella UDP Extension for Scalable Searches).
  • Added the ability to look for specific media types.
  • Added the ability to query for partial files as well.
  • Added "What's New?" queries.
  • Added smart search stopping / resuming options.
  • Added command-line option --minimized; useful when auto-starting gtk-gnutella.
  • Improved unpredictability of random numbers. Continuously collect new randomness from message events (RX, TX, dropping).
  • No longer uses download overlaps as soon as we know the TTH of the file.
  • When the download queue is auto-frozen due to lack of space, monitor the filesystem to auto-unfreeze when enough space is available again.
  • Can configure different amount of limits for various kind of search results.
  • [GTK2] Added missing configuration option for case-insensitive sorting.
  • [GTK] Flag search results bearing an alien IP as such, using both a tag (alien) and a color (deep pink).
  • [GTK] Added option to discard results bearing an alien IP (TRUE by default).
  • [GTK] Added option to restart session-only searches that still have pending downloads registered (FALSE by default).
  • [GTK] Search details now include a line to display available metadata.
  • [GTK] Fill in the Bitzi metadata column on the fly as results come in when we have cached ticket information available.
  • [GTK] Show media type filter attached to query, when known, in the search detail window.
Bug Fixes
  • Fixed *grave* routing bug whereby TTL was wrongly trimmed down by one extra step. Furthermore, the trimming threshold was wrong, which in effect caused ultrapeers to drop queries with TTL <= 2.
  • Fixed *grave* routing bug: was sending TTL>1 queries twice on the same connection when running as ultrapeer.
  • Fixed *grave* routing bug: was not properly forwarding duplicate OOB-proxied queries with a higher TTL (MUID was not altered the second time).
  • Make sure ~ expansion is done for path variables when changed at runtime. Fixes bug #3215847.
  • Was not processing updates of "search_reissue_timeout" from the GUI!
  • Filename sanitizer led to a crash when given a filename with leading spaces.
  • TTH downloads would crash when not receiving any data back.
  • An off-by-one bug prevented proper token validation, causing GTKG to not properly recognize the latest releases.
  • Avoid crash when attempting to connect to a node that would be internally flagged as "useless".
  • Fixed chunk selection algorithm to properly request from servers providing partial files.
  • Various "crash at shutdown time" type of fixes (occuring rarely and randomly).
  • Plugged hole leading to a file completing but not being checked for its SHA-1 when we have a few sources competing against each-other and all these sources end up ignoring data to preserve their connection.
  • Fixed crashes with GTK2 on some platforms at quit time by ignoring duplicate "quit" requests.
  • Fixed race condition that could lead to an incomplete QRP configuration.
  • Fixed important LRU cache management bug in the SDBM layer, which was causing data loss in persisted databases.
  • Head pings had their GGEP "PUSH" key improperly parsed.
  • [GTK] Was not saving the column size of the search list.
  • Fixed cause of random crashes in the VMM layer on systems using mmap() to serve uploaded files.
  • Dutch translation updated.
  • French translation updated.
  • By default, auto-clear completed and failed chunk downloads.
  • Changed user-visible connection state wording: "Connected" -> "Receiving" or "Awaiting data".
  • Added documentation for DHT "NOPE" values.
  • Allow one to disable partial file sharing in general, enabling it only for rare files (no full copy present).
  • Moved SDBM files to dedicated directories, either "gnet-db" or "dht-db".
  • Added visual indication that the download queue is frozen.
  • Added GUI configuration for "tth_auto_discovery".
  • [GTK] New colors for search results, to quickly spot partial hits, alien hits, hits with media-type mismatch and hits from firewalled sources with no push-proxy listed.
  • [GTK] Added expert-level configuration for the DHT mode, for whether DHT keys/values should be kept in memory, and for the SPAM SHA1 look-up table.
  • Option --disable-ipv6 was removed from we now always compile with IPv6 when Configure detects OS support.
Under the Hood
  • Tweaked aggressive chunk selection logic.
  • Let the RX link layer use the configured socket RX buffer size to determine the maximum amount of data that we can attempt to read in one system call, when the input layer cannot let us know how much data is pending.
  • Ensure we only keep valid address and port information when merging PUSH servent addresses for a given GUID.
  • Make sure fast assertion routines are never inlined or it would perturb stack traces due to missing offsets.
  • When building search request, be careful to not include unnecessary bloat at the end of the extension block or other GTKG nodes will drop the query.
  • DHT statistics now show local k-ball info along with the theoretical one.
  • Added probalistic model to randomly avoid cached DHT values too far from the key's theoretical k-ball during value lookups.
  • Smarter handling of "duplicate DHT values" (coming from the same publisher). We now allow fetching of these duplicates and retain different versions of the same value if we find a discrepancy (due to caching or partial re-publishing).
  • PUSH flooding detection no longer bans offending hosts, but only regulates the traffic by dropping flooding requests.
  • Compact extensions of forwarded queries to remove needless bloat: the XML is compacted, legacy HUGE requests to return URNs in hits are dropped, GGEP payload that are large enough are possibly compressed.
  • s390(x) has IEEE 754 floats.
  • Handle GGEP "u" in queries (SHA1 and bitprint URNs).
  • Avoid showing "negative" retry delays.
  • Turned some debugging-only assertions off.
  • Fixed bad test that led to a crash when receiving improper FIND_NODE messages.
  • Removed dependency to libxml2: now uses built-in XML support.
  • Converted bitzi cache to a persistent SDBM-based database.
  • Faster Bitzi request scheduling.
  • The Gnutella routing table now dynamically adjusts its size.
  • Deprecated GGEP "GTKGV1" in query hits, replacing it with "GTKGV".
  • Make sure we never send back duplicate SHA1 hits, even if they are sharing twice the same file from different directories.

Thanks to everyone who contributed to this bug-fix release in the form of feedback, bug reports or patches.

gtk-gnutella team

April 1st, 2011 -- Binary for Microsoft Windows Available!

Version 0.96.9 has been ported to Microsoft Windows and is now available for downloading.

All the gtk-gnutella features are available and the program runs on Windows with the same low-CPU and low-memory usage as when running under UNIX-like operating systems, including the gtk-gnutella shell (but then you have to launch it through the command line, not through the GUI by double-clicking on the icon).

Porting was done by your gtk-gnutella development team, by creating a thin POSIX-like layer on top of which the rest of the code can run without changes compared to the UNIX version. Note that this has nothing to do with Cygwin, and the resulting program is a native executable not requiring any Cygwin library.

You can download the installer and the PGP signature as usual.

Enjoy the quality of gtk-gnutella on Windows!

21 March 2010, Version 0.96.8 Released

Version 0.96.8 is a stable release, containing critical bug fixes for the previous release 0.96.7

Bug Fixes
  • Removed an obsolete assertion now that gtk-gnutella supports NOPE DHT values. This was causing a crash each time a NOPE value was received in response to push-proxies queries in the DHT.
  • Fixed memory alignment problem for non-forgiving CPU architectures.
  • The virtual memory manager would crash when the kernel starts allocating pages in zones we wrongly thought were already used.
  • Fixed long-standing bug in the Query Routing Table protocol where a RESET message with the wrong table size could sometimes be sent, causing the remote node to close the connection.
  • Make sure an ultrapeer is not publishing NOPE values in the DHT if support for the DHT was disabled by user, which would be triggering a fatal assertion failure.
Under the Hood
  • Fixed Makefile to ensure proper compilation under Gentoo's build scripts.
  • Push-proxy client support now makes sure there is a space after a leading GET or HEAD word in the HTTP request.
  • The DIME parsing layer now given more information in case of an error.
  • Let THEX downloads peruse any supplied Content-Length information from the server (applicable only when the output is not chunked).
  • The VMM layer is now smarter at identifying foreign pages when allocating blocks larger than a single page.
  • When sending BYE messages, do not shutdown the socket layer if using TLS.
  • Compilation cleanup for SunOS, Sun Studio, and versions of GTK < 2.5.0.

They are really identical to the ones present in version 0.96.7.

  • DHT code is currently sub-optimal for firewalled hosts.
  • Manual bandwidth tuning is currently necessary to allow for efficient DHT usage. Allow at least 8 Kib/s out, 15 KiB/s out being better. Also increase the lookup bandwidth to 32 KiB/s in and 6 KiB/s out, the defaults of 8 KiB/s in and 2 KiB/s out being very conservative.
  • DHT is enabled by default with a fixed (manually tunable) configuration. There is no auto-tuning and no adaptation to traffic conditions yet. You need to explicitly disable the DHT if you don't want to benefit from it.

07 March 2010, Version 0.96.7 Released

Version 0.96.7 is a stable release. The list below shows the most important bug fixed and improvements since the previous release.

Bug Fixes
  • Fixed memory leaks.
  • Do not unduly rewrite fileinfo trailers on restart, messing with the "mtime" filesystem information.
  • We were never forwarding to other ultra nodes queries that did not have a TTL of exactly 1 (severe bug impacting the network).
  • Queries not kept for a local file match were most often dropped and not forwarded (severe bug impacting the network).
  • Corrected detection of largefile support in Configure.
  • Fixed oversight in token validation, to be able to verify older versions.
  • Fixed metaconfig unit for systems without kqueue().
  • PARQ complained about lack of X-Queued header even if HTTP status was not 503.
  • Fixed sending of QUEUE callbacks to avoid hammering remote host, or stopping alltogether at the first timeout detection.
  • Was sometimes failing to reconnect to more nodes after disconnections.
  • Inverted logic was causing repeated UHCs queries when under the minimum amount of peer connections, causing undue traffic.
  • Tigertree verification would sometimes crash and delete the wrong slices after a TTH mismatch.
  • Fixed crashes at shutdown time due to inappropriate dropping of new messages in the message queues.
  • Fixed crashes at shutdown time due to improper checking in the dynamic query cleanup code.
  • Fixed invalid boundary test when server shrinks the requested file chunk.
  • Unfreeze all PARQ entries from the IP after serving a quick slot, or we could have several frozen entries for that IP with no possible escape.
  • Receptions of "GIV" and "QUEUE" were not checking whether the remote address was an hostile one.
  • Changed the Bitzi ticket-requesting URL, as the previous one was no longer responding correctly.
  • Fixed push-proxy support: requests (LIME/21) now only use v1 and acks (LIME/22) only use v2 because this is what LimeWire expects. GTKG was sending LIME/21v2 which confused LimeWire, in effect disabling the ability of GTKG to act as a push-proxy.
  • GUI node flags were not updated upon reception of a Push Proxy Acknowledgement (indicating the node became one of our push-proxies).
  • Fixed status bar which lost the GTKG URL as soon as a new version was announced.
  • Fixed crash when a compressed connection was closed and had never been given any data to compress.
  • Fixed behaviour on DHT value lookups when the key exists but is not holding the proper value types.
  • Fixed HTTP partial range merging logic.
  • Fixed logic for push-fallback on connection timeouts.
  • Fixed improper GUI status display when connecting to a push-proxy.
  • Could wrongly discard a perfectly good push-proxy.
  • Prevent "found more recent metainfo" warnings at next startup by properly flushing the metainfo database at shutdown time.
  • The "Force push mode" menu entry could have no effect if gtk-gnutella had determined the host did not require a push.
  • Avoid innocuous duplicates in the persisted download file.
  • Better resuming of downloads on session restarts.
  • Increased success rate on downloads from firewalled hosts.
  • Completed support for DHT publishing: DHT is now fully functional.
  • DHT bandwidth usage is now disaplayed in the GUI.
  • Added support for GGEP XQ (eXtended Query) as used by LimeWire for search terms longer than about 30 characters.
  • Try to decipher incorrectly encoded query flags from buggy Shareaza.
  • Parse incorrectly formatted X-Alt header from buggy Shareaza.
  • Implemented PFSP 1.0a: now emits and handles new X-Available header.
  • Added some MIME types and file extension mappings.
  • Added comand-line switch --compile-info to print some information that is hardcoded at compile-time.
  • Persist known TTH roots in magnets.
  • Swapped leaf and ultrapeer slots for GGEP UP in compliance with LimeWire which does not follow the published specification (so we don't either now but we are compliant with the de-facto standard).
  • Will now remove uncompressed ultra connections when full and getting a new compressed one.
  • Whitelist can now support TLS hosts and will refresh DNS mappings regularily.
  • Improved granularity of the background task used to scan the library in order to prevent noticeable processing freezes as much as possible.
  • Redesigned the output of the shell "status" command to show more information and display status flags (shown as icons in the GUI).
  • Added liberal parsing of urn:sha1: and urn:bitprint to cope with clueless sites using hexadecimal instead of base32 to encode the hashes.
  • Added -v option to the shell command "props" to also display values along.
  • Added real shell-like string parsing, and fixed escaping to work correctly.
  • Added the ';' separator to be used to separate mutiple shell commands.
  • Allow crashes and fast assertions "soft" failures to be timestamped.
  • Don't answer to UDP pings from bad nodes, which include "alien" hosts.
  • Loop through the TCP push-proxies more quickly until one can relay our push.
  • Passively revitalize PUSH routes and wakeup starving downloads.
  • Attempt to collect push-proxies passively from relayed query hits.
  • A completed file waiting for being moved accross filesystems will now be flagged as such in the GUI "Downloads" pane.
  • Detect and fix improper 503 HTTP status code replies when 416 was meant (broken HTTP replies from Foxy, Shareaza, and maybe others).
Under the Hood
  • DHT (Distributed Hash Table) is now enabled by default.
  • Reduced blackout period between two DNS server name lookups to 30 minutes.
  • Updated PFSP specifications (partial file sharing) to version 1.0a.
  • More statistics.
  • Always use exact time when logging, not the cached time.
  • Align to LimeWire's settings for DHT expiration and republishing periods.
  • Do not emit any PFSP header when seeding a finished file.
  • Even if bandwidth is tight, force emission of the X-Hostname header under certain circumstances because this information is precious.
  • No longer constantly monitors for unsolicited UDP traffic, which will save precious CPU cycles.
  • Improved malloc tracking by reporting symbolic names in stack frames.
  • Optimized ultrapeer TX compression settings to reduce memory requirements, saving 288 KiB of RAM per Gnutella node connection (leaf or ultra).
  • Increased default amount of ultrapeer connections to 42.
  • Optimized memory footprint of the simple hashtable and allow it to be downsized as well.
  • Consider a HEAD Ping message to be unsolicited UDP traffic.
  • New shell command "memory dump" available when malloc stats compiled in.
  • Some documentation held in SVN cannot be packaged on Debian, so it was moved to a separate directory that is left out from the packaging manifest.
  • SDBM improvements for greater runtime performance and data consistency.
  • Added DHT root node caching (k-closest nodes of a target KUID).
  • Tuned DHT node lookups for more performance.
  • Can now hold the SPAM look-up table in an SDBM database instead of memory.
  • The directory holding "incomplete" files is now lock-protected to prevent two different gtk-gnutella instances from using the same one.
  • Added long-due zone garbage collector, called when gtk-gnutella is "idle".
  • Tuned block size to avoid wasting too many bytes in zones.
  • Improved the virtual memory management layer to limit fragmentation, especially for servents running over long periods of time (weeks).
  • Revised the vitrual memory management page-caching algorithm.
  • Politely deny handshaking with peers presenting an X-Auth-Challenge header or an FP-Auth-Challenge one.
  • Added support for firewalled alternate location collection and propagation through the X-Falt header (requires that the "fwalt/0.1" feature be advertised in X-Features).
  • Added a non-persistent "alien" cache to keep track of IP:port of nodes that do not belong to the Gnutella network.
  • Increased the buffer size of datagram sockets to 32KiB to allow reception of bigger messages: it is not uncommon to get OOB query hits larger than 4KiB.
  • Count (and show) amount of launched SHA-1 and TTH file verifications.
  • Translation updates.
  • DHT code is currently sub-optimal for firewalled hosts.
  • Manual bandwidth tuning is currently necessary to allow for efficient DHT usage. Allow at least 8 Kib/s out, 15 KiB/s out being better. Also increase the lookup bandwidth to 32 KiB/s in and 6 KiB/s out, the defaults of 8 KiB/s in and 2 KiB/s out being very conservative.
  • DHT is enabled by default with a fixed (manually tunable) configuration. There is no auto-tuning and no adaptation to traffic conditions yet. You need to explicitly disable the DHT if you don't want to benefit from it.

29 March 2009, Version 0.96.6 Released

Version 0.96.6 is a stable release. The list below shows the most important bug fixed and improvements since the previous release.

Bug Fixes
  • #1932909 "columns in search window do not scale properly".
  • Fixed improper HTTP chunking when outputting chunks larger than 64 KiB.
  • #2628899 "tries to download from my old self after IP changes".
  • Was not always resuming the interrupted SHA-1 computation of a finished file when servent was closed in the middle of processing.
  • Fixed bad range checking test in the download part.
  • Was not paying attention to the "give_server_hostname" property and instead sent "HNAME" GGEP extensions in query hits provided a non-empty name was defined as the "server_hostname".
  • Fixed improper upload slot counting which introduced race conditions, sometimes leading to having more slots used than the configured maximum (in addition to the "quick" upload slots).
  • Prevent occasional crashes at shutdown time, during subsystem cleanups.
  • Fixed corner cases where we could lose a server hostname and downright bug where we discarded the hostname after a DNS lookup if the subsequent connection attempt did not succeed.
  • Refuse to share certain directories: /, $HOME, $GTK_GNUTELLA_DIR, and the incomplete and corrupted directories.
  • Downloads GUI: added checkboxes to invert the select/filter patterns.
  • Downloads GUI: added "Modified" column and detail showing the time-stamp of the last file modification.
  • Optional beautification operations on filenames: strip leading "-", remove consecutive "_" and prevent "_" surrounding punctuation characters.
  • Fixed significant performance issue in the Gtk+ 1.2 front-end: update of upload statistics was O(n) but is now O(1).
  • Background TTH file verification now lights an icon in the GUI.
  • Show TTH tree depth in the download "Details" pane.
  • Update the bitzi meta-data info box when a query finishes, so that it is not required to click on the result again after requesting bitzi data.
  • Added MIME type column for search results.
  • Added "Last Request" and "Last Upload" columns to the Upload History.
  • Almost complete DHT support (missing only publishing of data), but code needs to be explicitly enabled by setting "enable_dht" to TRUE. The DHT knows how to look for alt-locs for files and push-proxies for firewalled hosts, and will store local data for others to query.
  • New shell commands "stats", "download", "echo".
  • It is now possible to rename files being downloaded (through GTK2 or shell, no support in GTK1).
  • Added more filename extensions to the built-in search filters.
  • Switch resources after getting an HTTP error if the connection is kept alive and the error permits follow-ups (non-busy conditions).
  • Improved ability to switch resources after file completion by ignoring trailing swarming data, to keep the connection alive.
  • Bitzi tickets are refreshed when explicitly requested, avoiding reuse of stale meta-data.
  • Completed files are displayed during hash verification.
  • Only propagate good alt-locs for files we are downloading, i.e. addresses of hosts which we know to be serving that file because we contacted them.
  • Many new statistics counters.
  • Allow scheduling of special downloads without considering per-host limits, as these are of a much shorter duration (THEX and browse host requests).
  • Always seed completed files, regardless of their size (no PFSP minimum as with partial files), when their SHA-1 has been verified.
  • Incorrectly encoded Bitzi meta-data is translated to Unicode.
  • Browse-host responses are sorted alpha-numerically on relative pathnames to allow users to relate files together if they don't understand GGEP "PATH".
  • Improved routing of PUSH messages by also looking whether targeted hosts happen to be one of our immediate neighbours.
  • Updated Norwegian Bokmal and Spanish translations.
Under the hood
  • Parse legacy Shareaza THEX URIs "urn:tree:tiger/:" (extra "/" here).
  • Handle non-standard X-Thex-URI headers if peer provides a valid X-Content-URN header (Shareaza
  • Also attempt to give priority to the last "pfsp_last_chunk" bytes of downloaded files, since that can contain important indexing information to enable pre-view of partial video files.
  • More MIME types known (derived from file extensions).
  • Can now download THEX data at a tree depth of 11 for files larger than 1 GiB.
  • Can download sub-optimal THEX data, as non-optimal data is better than none, but keeps looking for THEX data at the optimal tree depth nonetheless.
  • Re-implemented scanning of shared directories as a background task so that the process (not just the GUI) is fully responsive during the whole scan.
  • Let the background task scheduler compute the proper amount of ticks to use for each task.
  • Upload statistics now record the file's SHA-1, so that we can consolidate partial file sharing with library sharing statistics, with the filename being forced to the library's filename.
  • Avoid starting moving a completed file if there is not enough space on the targeted file system.
  • Recognize and propagate the "DHT" GGEP extension in pongs.
  • Added support for "DHTIPP" GGEP extension in pings, used for DHT bootstrap.
  • Added more entropy to the random number seed.
  • Plugged a few memory leaks.
  • No longer send SHA-1 queries on the Gnutella network. They are now performed through the DHT, which has the suitable topology to do so efficiently.
  • Fixed UDP bandwidth computation, and removed any limit on UDP incoming.
  • Updated list of hostile IP address ranges, Geo-IP data, spam patterns and spam samples.
  • Property loading from files was in O(n*n), made it O(n).
  • Now detect property files being blindly copied over from another gtk-gnutella's config directory and reset properties whose value needs to be unique.
  • The GUID and the KUID (Kademlia ID, the DHT node ID) were made sticky.
  • Optimization of QRP lookups in tables ranging from 16k to 2M slots.
  • Limit amount of hits to 10 per query hit packet, as LimeWire chokes otherwise.
  • Limit amount of alt-locs in hits to 10 or LimeWire chokes.
  • Keep connection alive when reporting an HTTP error to allow remote resource switching if necessary.
  • Emit and parse new X-Downloaded header, apparently introduced by LimeWire.
  • Added parsing of X-FW-Node-Info headers to grab push-proxies from firewalled hosts, as well as gather the proper GUID and host address/port.
  • Emit X-FW-Node-Info if node is firewalled but continue to list our push-proxies in the standard X-Push-Proxies header.
  • Avoid endless aggressive chunk splitting during swarming.
  • Proper parsing of comma-separated values in Accept and other Accept-Encoding HTTP headers.
  • Reject UDP packets from unspecified addresses.
  • Drain more data out of the UDP receive buffer to prevent it from filling up.
  • Strip at most 5 trailing characters from words when building the QRP table, thereby inserting less radices and making the table more sparse.
  • Removed workarounds for dealing with broken 0.96.2 nodes and earlier 0.95.x.
  • Extended syntax for push:// exact sources in magnets to be able to supply all the known push-proxies, even if that is an empty set. Since downloads are persisted as magnets, this also allows keeping all the previously known push-proxies across sessions.
  • Upgraded PARQ to version 1.1 (mostly specification cleanups).
  • Added additional anti-hammering for cases where many files on the same server are queued and gtk-gnutella is configured to launch more than 1 connection per IP. Connection attempts to the same server are now limited to 5 per minute.
  • DHT code is still experimental, although functional: configuration of parameters can only be done through the shell, and there is no support for publishing yet.
What is the DHT good for?

Now that gtk-gnutella supports the DHT (an acronym standing for Distributed Hash Table), what are the direct benefits for gtk-gnutella users?

If you enable the DHT code in gtk-gnutella, you will be able to benefit from these new features:

  • Use source-less magnets. The DHT can locate files by their SHA-1. Websites like Bitzi collect this information along with further metadata about files. Bitzi also provides magnet links you can readily drag and drop onto gtk-gnutella's main window or copy and paste into its search box to search and download the desired file. Of course, magnet links can also be manually constructed as long as you know the SHA-1 of the file. Contrary to regular Gnutella searches, the DHT will find quickly (in less than a minute usually) whether someone has published that it was sharing the file.
  • No spam or fakes. Look up the content you want at places you trust (like Bitzi). Magnet links can link to known sources, too, but usually don't. Therefore, they are conveniently short, look like URLs and can be posted anywhere: forums, blogs, index sites, emails, IRC etc. As they link to content instead of a specific location, they are practically permantly valid and never expire. Using your trusted communities to exchange magnet links gives you the benefit of avoiding all spam and fakes that you may suffer from with regular searches.
  • Better success with firewalled sources. As firewalled hosts publish their push-proxies in the DHT, you can start a download by using only a push: source (consisting only of the servent's GUID) and gtk-gnutella will be able to lookup the DHT for you and find what the current push-proxies are for that host. Again, it is very quick and if that host has published its push-proxies, gtk-gnutella will find them.
  • Faster downloads. With the DHT, you can acquire additional alternate locations for files and use native Gnutella swarming abilities to very efficiently and reliably download files.
  • Improved session resuming. If you shut-down gtk-gnutella and restart it later, it will lookup for new push-proxies (the old ones that were persisted are probably obsolete) and new sources for the files which are pending in the queue, possibly re-seeding some downloads that were orphan (without active sources) for a long time.

If something has been published in the DHT (sources for files identified by their SHA-1, push-proxies for firewalled hosts identified by their GUID), it will be found in a matter of seconds. If the search is unsuccessful, it means the data is not present at this time in the DHT. There is no horizon consideration as in Gnutella searches. The only requirement is that you know how the published data is keyed in order to find it.

The key to make all that possible is to use a Gnutella servent that is capable of joining and querying the global Gnutella DHT, currently supported by LimeWire (and all its derivatives) and gtk-gnutella. The next release will add DHT publishing to gtk-gnutella to make it fully productive.

Who should activate the DHT code? Ideal nodes are leaf nodes which are not firewalled, then ultrapeers. If your peer is firewalled, you can still enable the DHT code but it will be less efficient currently for the network. The more nodes are present in the DHT, the longer they stay connected, the more powerful the DHT becomes.

Below is the ChangeLog entry for the release.

Bug Fixes
  • Portability fixes which affect the ARM architecture.
  • Ultrapeers could be unnecessarily demoted to leaves in auto mode.
  • [GTK2] Fixed a bug that could cause spurious assertion failures or memory corruption.
  • Fixed bug that might have caused truncation of printed numbers in certain places.
  • Rewrite the upload_history file if the history was cleared.
  • Fixed crash caused by an assertion failure that could occur if IPv6 support was disabled at compile-time.
  • Fixed buggy utf8_is_valid_data().
  • Fixed a couple of small technical mistakes in translations.
  • Fixed compilation for Cygwin without IPv6 support.
  • Updated French translation.
  • Updated list of hostile IP ranges.
  • Updated list of bootstrap caches.
  • Updated list of country names and codes for Serbia and Montenegro.
  • Turkish translation.
  • New shell commands: online, offline, props, status.
  • The search list allows selection of multiple items and applying actions to them now.
  • Added a tray icon to hide the gtk-gnutella application windows. This feature requires Gtk+ 2.10 or newer.
  • Added a limit of downloads per file which defaults to 40 to prevent using an unreasonably large amount of sources.
  • Keep certain irrelevant columns empty for "local:" searches instead of showing bogus data.
  • Added README.Debian with instructions how to compile gtk-gnutella yourself on Debian-derived systems.
Under the hood
  • Rewrote "fast" assertions so that they are sufficiently portable and do not mess with debugging. Thus they are always enabled now which reduces code size signifcantly.
  • The TLS cache is now persistent without SQLite too.
  • Disabled reservation of Gnutella slots and vendor limits because it's not useful with the current population of Gnutella.
  • Disabled GWebCache updates.
  • Configure bails out now if a mandatory dependency e.g., libxml2, GLib, zlib isn't available.
  • Added -Wshadow to the default compile flags for GCC for even cleaner code.
Checksums of the source tarball:
  • SHA256 (gtk-gnutella-0.96.3.tar.bz2) = 6079661ffeb78ae480cf37cf9954d0c437d415363aa4133268b732700b52be80

17 October 2006, Version 0.96.2 Released

Version 0.96.2 is a stable release. Fixing important bugs and adding a couple of improvements.

Below is the changelog entry for the release.

Bug Fixes
  • Fixed bug #1467793 uname() return value.
  • Fixed bug #1467681 weird HTTP acknowledgment.
  • Fixed bug #1422526 `Drop results' should prepend, not append, to filters.
  • Fixed bugs in the dynamic querying logic that caused leaves to receive very few results through gtk-gnutella ultrapeers.
  • Fixed crash on 64-bit platforms when using the navigation tree.
  • Fixed format mismatches in some translated message catalogs.
  • Updated French, Japanese and Ukrainian translations.
  • Updated list of hostile IP ranges.
  • Updated list of bootstrap caches.
  • Updated list of country names and codes.
  • Italian translation.
  • Fairly complete support for magnet-links; magnets can be passed per drag & drop or entered via the search box. Magnets can be generated from the search results display and the downloads display through the context menu.
  • SHA-1 based spam filtering.
  • Built-in spam detection for certain kinds of spam.
  • [GTK2] Overhaul of the downloads display.
  • [GTK1] Downloads can be sorted albeit the sorting does not persist.
  • Compiling the topless is variant is now as easy as ./Configure -Oders -Dd_headless.
  • Support for several command-line options like --help.
  • A local shell interface accessible with gtk-gnutella --shell.
  • New shell commands nodes and shutdown.
  • All downloads are stopped now if the disk apparently filled up.
  • Caching of TLS-support allows automatic use of TLS.
  • ~/.gtk-gnutella/whitelist supports the tls: as well.
  • More search results columns for experts (hidden by default).
  • Diverse IPv6 settings can be configured in the GUI now.
  • The setting IPv4 and IPv6 works now; the default is IPv4 only.
  • Results bearing no SHA-1 are suppressed by default.
  • Results from hostile IP ranges can be made visible; they are discarded by default.
  • One's own shared files can be search by using the prefix local: for searches. Local searches uses regex syntax unlike Gnutella searches. local: alone will list all shared files. Local searches results allow drag & drop and generation of magnet links.
  • Support of Socker for access to privileged TCP and UDP ports below 1024.
  • Optionally bind sockets to a configured address instead of the wildcard address.
  • Support of IPv6-to-IPv4 Transport Relay Translators (RFC 3142).
Under the hood
  • mmap()-based memory allocation to decrease fragmentation and increase performance.
  • Support of socket option TCP_DEFER_ACCEPT (Linux).
  • Support of accept() filter dataready (FreeBSD).
  • Support of /dev/poll on Solaris and IRIX.
  • Sharing of file descriptors so that we don't require a file descriptor per swarm source but only one per file.
  • Use of pwrite(), pwritev() for flushing download buffers.
  • Reopen log files on SIGHUP if the command-line options --log_stderr or --log_stdout are specified which is useful for topless mode.
  • Disabled following of HTTP redirects.
  • Support of deflate transfer-encoding for all downloads.
  • Support for compression of UDP packets.

31 July 2005, Version 0.95.4 Released

Version 0.95.4 is a bug fix release. Several bugs were fixed. We advise everyone to upgrade to this version of GTKG as it is the most stable version right now.

  • The last-byte download bug, where a download would not complete if only the last byte needed to be downloaded, has been fixed.
  • Preliminary browse-host support, allowing other servents to browse the files that are shared. This is disabled by default.
  • GTKG will detect online status again after temporary network failure.
  • The .desktop file and application icons are now properly installed.
  • Downloads are now sorting in a more logical way.
  • Bug fixes in UTF-8 support.
  • Doxygen documentation updates.
  • Japanese and Spanish translation updates.

22 May 2005, Version 0.95.3 Released

Version 0.95.3 is a bug fix release. Several bugs were fixed. We advise everyone to upgrade to this version of GTKG as it is likely that the bugs we fixed will cause problems for you at some point.

  • Fixed a potential denial-of-service problem.
  • Fixed OOB reply code which would lead to failed assertions.
  • [GTK1] Show Enable option and Remove button in Filter editor again.
  • Fixed inadvertent truncation of large files (> 4 GB).
  • Compatibility fixes for 64-bit platforms.

10 May 2005, Version 0.95.2 Released

Version 0.95.2 is a bug fix release. Several bugs were fixed. We strongly advise everyone to upgrade to this version of GTKG.

  • GTKG generated up to four times more traffic than was needed between GTKG Ultrapeer and GTKG leafs.
  • Improved firewall status detection: if you are not firewalled then GTKG is now less likely to claim that you are.
  • Fix a build problem for some versions of Glade
  • A few minor bugs fixed

6 May 2005, Version 0.95.1 Released

Version 0.95.1 is a stability release. Stability has been greatly improved since 0.95, so if you had any kind of trouble with 0.95 then these problems are likely to be gone. As usual everyone is encouraged to upgrade to the new version.

  • Bitzi tickets are now persistently cached so that tickets are available again after restarting GTKG.
  • Improved Unicode support:
    • The use of Unicode in queries now matches that of other Gnutella clients. This will make it easier to search for file names which contain non-Latin characters. At the time of release only gtk-gnutella 0.95.1 and Limewire will respond properly to Unicode queries.
    • Files are shared with their names converted to UTF-8, and downloads are stored with UTF-8 file names.
    • Unicode support is now built-in, we no longer depend on the ICU library.
  • Search improvements:
    • It is now possible to enter negative matches in search strings. If you enter "blah -blubb -nada" as search string, results matching "blubb" or "nada" are automagically filtered.
    • The search filter allows filtering for files larger than 4 GiB and you can also use suffixes like KB, KiB, MB, MiB etc.
  • [GTK2] GUI updates:
    • You can drag & drop items under Downloads->Files e.g., to pass them to a audio/video player, picture viewer etc. Drag & drop is dangerous when used on files from unknown sources. You have been warned.
    • GnutellaNet has a new item "Reverse DNS lookup" in its context menu to perform a lookup of the peer's IP address.
    • XML data contained in search results is shown in the results details pane.
    • The search edit field has been moved to the top.
    • The Downloads pane was split into "Active Sources" and "Queue".
    • Compatible with GTK 2.6.x and older versions.
  • The GUI uses SI prefixes according to IEC 60027-2 (2000-11) Ed. 2.0 everywhere, so hard disk vendors won't fool you any longer.
  • Compatibility fixes to allow compilation on more architectures, including 64 bit architectures.
    • Systems with a sendfile() that is not largefile compatible work again. On platforms without sendfile() we now use mmap() for improved efficiency.
  • There are now two hostiles.txt, a system-wide ("global") and one in the ~/.gtk-gnutella directory. So you only need to put private additions into ~/.gtk-gnutella/hostiles.txt. These files are also automagically reloaded on change, so you don't need to restart gtk-gnutella to make the changes effective.
  • Updated listings for geographic information, bogus addresses and spam sites.
  • Greatly enhanced stability as compared to 0.95 due to many bug fixes. Other noteworthy bugs fixed are:
    • gtk-gnutella as ultrapeer was not routing any searches iff uploads had been disabled.
    • Problems with the UDP/TCP port setting have been fixed (bug #1091827).
  • German, Japanese, and Spanish translation updated.

27 November 2004, Version 0.95 Released

With the release of version 0.95 gtk-gnutella supports the state-of-the-art features of the Gnutella network. In terms of Gnutella features version 0.94 is now considered a deprecated servent. Every gtk-gnutella user must upgrade to 0.95 as soon as possible to get the expected performance from the network and keep it healthy.

  • GUI updates:
    • Enable drag and drop for magnet links
    • [GTK1] Search results have less columns, and the hit details are now displayed in a separate pane underneath.
    • Visual progress indicator correctly shows newly downloaded fragments, shows fragments currently available for download more accurately, and active downloads are marked with arrows.
    • The maximum amount of search results has been lowered to 1000. Please use filters or more specific queries to find what you are looking for if you get many search results.
    • A detailed view has been added to the search results to show all available information for a search result.
    • The status bar will now give feedback about the contacted host caches.
    • Gnutella node stats can now show how many bytes were sent/received.
    • In the node pane, right-clicking now allows to configure which columns should be displayed, just like in the search pane.
    • More general statistics in the stats pane. It is possible to see TCP and/or UDP traffic stats separately (for messages only, not flow-control).
  • Bitzi support has been added to retrieve additional information on possible downloads. See for details.
  • The geographic location of hosts can now be shown courtesy of MaxMind.
  • Recently developed features of the Gnutella network are now supported:
    • High outdegree provides better connectivity between Gnutella hosts. The maximum TTL in the network is now 4 and ultra nodes must maintain at least a connection with 30 peers.
    • Last-hop QRP between ultra peers.
    • Dynamic querying support, allows selective querying of peers instead of simply broadcasting the query. It is used for leaf queries and for your queries when running as an ultra node.
    • OOB (out of band) query hits lets other servents deliver search results directly to you instead of going through the Gnutella network.
    • OOB proxied queries, allowing direct hit delivery at the ultra node level for queries emitted by legacy leaves.
    • GTKG will now prevent firewalled hosts from running as ultra nodes.
    • In "auto mode", GTKG will revert to leaf mode when uploads are stalling at an abnormally high rate, indicating bandwidth is saturated.
  • UDP is now also supported as a transport protocol in addition to TCP. You may need to make changes to your firewall settings to take full advantage of this. The UDP port used is the same as the one used for TCP.
  • Firewall detection has been improved to include UDP firewalling detection.
  • Clock skew computation for hosts not running NTP has been redesigned. Also, GTKG will now automatically detect a locally running NTP.
  • Large file support has been added, so that files over 2 Gb can be used.
  • Japanese translation added.
  • French and German translation updated.

10 July 2004, Version 0.94 Released

While 0.93 was improved for stability with the 0.93.4 release, the just released 0.94 contains some nice new features, while it should be at least as stable as 0.93.4:

  • GUI updates:
    • File info pane renamed to "Downloads".
    • Downloads pane renamed to "Sources".
    • Progress of a download can now be visualized. This will show which fragment of a file has been downloaded, which fragment gtk-gnutella is currently downloading and which fragments are availalbe on the Gnutella network.
    • Uploads and download sources pane now contain a visual progressbar.
    • The GTK2 GUI can now be resized smaller than a width of 933 pixels.
    • Search results now include an extension column, so you can sort by file extension if needed.
    • The Gnet stats panel and the statusbar now include horizon statistics.
  • New Gnutella extension HSEP/0.2 included. This will give you an estimation of the horizon size. This includes the number of reachable nodes, files and the total size of all files on the network.
  • The remote shell now includes a command "HORIZON", which will output horizon stats.
  • If no default port is specified, gtk-gnutella will now bind to a random port and will use that port from then on.
    If you are behind a firewall and have routed a port to gtk-gnutella, please check that gtk-gnutella is still running on the port you want it to!
  • Will parse up to 150 hosts in a gwebcache reply to bootstrap from.
  • New hostcache to make gtk-gutella connect to the network more quickly.
  • Dutch translation updated.
  • German translation updated.
  • Spanish translation updated.
  • French translation updated.
  • Hungarian translation updated.

6. Febuary 2004, 0.93.x branched off

Today Jeroen created the B-0-93 branch in CVS. Only fixes are supposed to go there. We think that 0.93.3 is already pretty stable, but we want to improve stability even more with 0.93.4. The HEAD branch of CVS will become 0.94.

To fetch the latest fixes for 0.93.3, you can check out the B-0-93 branch using the following commands:

cvs login
cvs -z3 co -r B-0-93 gtk-gnutella-current

When prompted for a password for anonymous, simply press the Enter key.

25. January 2004, Version 0.93.3 Released

This is primarily a bugfix release with few user-visible changes. There have been several bugs squashed and memory leaks eradicated. Please upgrade to this version.

For more changes, file MD5sums, etc go here.

gtk-gnutella team

12. January 2004, Bugfix release coming soon

It is recommended that you either wait for this release or compile from the Official CVS snapshot, which should be at least as stable as the releases and has fixes for most of the known bugs. If you want to help stamp out bugs for this release please read the Bug Report Howto and report your bugs to the Bug Tracker. I think it should be well worth the wait since there have been some very nice improvements to gtk-gnutella lately.

Update 14.1.2004: We have problems finding a memory leak in the CVS version of gtk-gnutella at the moment and need to do more testing which will probably delay the release of 0.93.3.

gtk-gnutella team

8. January 2004, Contributed packages for 0.93.2

I have posted unofficial Redhat-9, Fedora, Mandrake-9.2, and Slackware-9.1 packages on my web site. See the README file there for instructions on how to verify these gpg signed packages.


7. January 2004, New GTK-GNUTELLA Logo?

Think the banner logo at the top of this page is ugly? Maybe you can do better! Send your images (or preferably a link to them) to the -devel or -users mail list. If your logo is chosen you will win... um, well, let's see - a place among the Hall of Fame of gtk-gnutella contributors and a special notice on the webpage.

Update 14.1.2004: Images will be accepted until the 31th January 2004.

15. June 2003, Version 0.92 released

You can get this new version from our download section. Here are some of the changes since 0.91.1, the latest stable release:

  • GTKG can be an ultrapeer.
  • Client-side PFSP support (partial file sharing)
  • Added full PARQ support (Passive / Active Remote Queuing).
  • Quicker connection to the network and improved bandwidth usage.
  • Asynchronous DNS lookups.

For more changes go here.

gtk-gnutella team

25. May 2003, Version 0.92 candidate released

  • PARQ is now fully implemented.
  • Filters out hostile IP addresses.
  • New icons for showing node state (leaf or ultra mode).
  • New "Fileinfo" pane in the download screen. Not finished, but will show the currently registered downloads and their status.
  • Minor bugs fixed.
  • GTK2 version has grouping of same files in the search pane.

WARNING: Leaf node bandwidth is now stolen from HTTP when running in ultra mode. If that brings outgoing HTTP bandwidth to 0, sharing is disabled.

gtk-gnutella team

3. Mar 2003, Version 0.92 beta2 released

This is a bugfix release. If you used beta1, please update to this beta. Also note that precompiled versions only exist for GTK1 as GTK2 is too slow for most users right now.

  • Fixed Gnutella web cache hammering. A buggy test caused GTKG to query the caches each time it was establishing an outgoing connection!
  • Domain name resolution for Gnutella web cache are now done asynchronously. The GUI will no longer freeze due to a DNS request.
  • Some performance improvements: removed the most important bottlenecks.
  • Fixed flow-control bug, exercised mainly with compressed connections: they could stall abruptly, no longer transmitting data.
  • Fixed assertion failure in PARQ client code.
  • Fixed incomplete clearing of downloads from a given host.
  • Warning: The amount of bandwidth configured for leaves is currently automatically added to the HTTP connections when not in leaf mode, regardless of whether "use surplus bandwidth" is activated. This will change in the release.

9. Feb 2003, Problems when compiling 0.92 beta?

If you have difficulties compiling the GTK2 versions of our packages, then pick the GTK1 equivalents or compile from CVS. The packets seem somehow broken :(
We'll investigate that.

Markus "guruz" Goetz <guruz at guruz dot de>

8. Feb 2003, Version 0.92 beta released

We are proud to release the beta version of our upcoming 0.92 release. It features many changes, so please test it as thoroughly as possible and report any bugs to the IRC channel or the mailing lists :)

  • Now supports Ultrapeers, which means GTKG can work as an ultra node or as a leaf node. You can still run as a normal node, although this is not something wise to do, because that will likely relegate you in a small part of the Gnutella network.
  • The GTK2 front-end is no longer experimental, albeit it is slower than the GTK1.2 front-end. This is due to the somewhat inefficient implementation of the underlying GTK library. Don't use GTK2 unless you have the equivalent of a 1 GHz Intel chip.
  • Added client-side PFSP support (partial file sharing). GTKG can download from servers holding partial files.
  • Added client-side PARQ support (Passive / Active Remote Queuing). GTKG can now queue downloads from either active-queuing servers or PARQ.
  • New Gnet statistics: flow-controlled packets per TTL and hops.
  • The "Type" column in the Gnet connection pane was turned into "Flags".
  • Added support for GGEP in pings/pongs/pushes: those packets are now accepted and forwarded to connections advertising GGEP support.
  • New "use surplus bandwidth" setting: all unused bandwidth for Gnet or HTTP can be stolen by the other in case it needs some.
  • Added count for total bytes uploaded and downloaded.
  • Added support for vendor-specific messages.
  • The "prefer compressed connections" settings no longer works as expected when running in non-normal mode.
  • New hops-flow support: remote flow-controlled connections can now warn us that thye are flow-controlling us, and so we can drop queries immediately instead of sending them, saving outgoing bandwidth.
  • Will now show the GTKG version in query hits.
  • The queue now shows the count of alive downloads, as well as the queue count. An "alive" download is an entry for which the remote server replies.
  • Changed the connection algorithm: will now attempt to connect to more nodes than really configured, dropping the surplus connections later, when needed at all.

P.S.: We're wishing Raphael a happy flight & stay in the land of the DMCA ;)

27. Jan 2003, We are alive

This is just a small information that gtk-gnutella is still under development. Ultrapeer support on the ultrapeer side and on the leaf side is currently in CVS, the client side of the partial file sharing protocol (PFSP) too. Also someone (MrJoe ;) is doing queueing support. Great news, isn't it? :)
If you want the bleeding edge, go to the development page and look how to get the CVS version.

24. Dec 2002, Merry X-Mas

The gtk-gnutella team wishes everyone on the world a merry and happy x-mas! If you want to give something back to the gnutella network, support it by running a GWebCache (and, of course, gtk-gnutella ;-).

25. Nov 2002, New webpage maintainer

Hello people,
I am the new maintainer of the gtk-gnutella webpage and i want to bring more information and help to users visiting us :) If you have any questions or additions feel free to send me a e-mail.
And remember we still need more developers!

22. Nov 2002, Version 0.91.1 stable released

A minor bug-fixing release, which also happens to contain all the working new features that have been already added in the 0.92u version.

  • Will now verify the SHA1 of downloaded files in the background.
  • New configuration parameter for the directory where "bad files" not matching their advertised SHA1 should be put (don't forget to configure it, as it defaults to /tmp).
  • Files are now copied in the background, so it is possible to setup the various "download" directories on different filesystems.
  • Node connection time and remote node's uptime (if available) are now shown.
  • It is now possible to paste a "magnet:" URI in the search to launch a SHA1 search.
  • The "connection indicator" at the bottom left is now a toggle. Depressing it will terminate any Gnet connection but will continue to serve uploads and process downloads.
  • The active download status now shows how many sources are available and how many are currently active (i.e. downloading). It will also show the estimated remaining time for the whole file, as well as the global reception rate for the file, accounting for all currently active sources.
  • Fixed bug that prevented proper downloading from recent BearShare (4.1.x or better) and Shareaza (1.6.0.x or better) nodes when the SHA1 of the file is known.
  • Will now protect against "PUSH floods" by banning the relevant IPs.
  • At startup, scan the download "tmp" dir for orphan files and reintegrate them into the fileinfo database, moving completed files to the relevant directory (depending on whether its SHA1 checked OK).
  • Minor bug fixing: improper countdown for push timeout when falling back, fixed corner-case processing that could lead to crashes or incorrect behaviour, accidental localization on X-Live-Since headers, freezing of the GUI when clearing many uploads, obscure portability fixes.

We strongly recommend that you upgrade as soon as possible.

19. Oct 2002, Version 0.91 stable released

After nearly 3 months of development efforts, we are proud to present the new 0.91 stable version. It features many changes since the latest stable 0.90 release. Among them:

  • Now uses HTTP/1.1, which implies support for persistent connections.
  • gtk-gnutella will now monitor whether we're connected to Internet and slow down its connection requests when it detects the connection was broken (after a delay of ~3 minutes at most).
  • Download swarming is now supported: gtk-gnutella will download different portions of the same file from many hosts, as long as alternate sources are available.
  • The download mesh (alternate source collection during downloads) is now used to fill the download queue with more sources.
  • Alternate locations can also be passively collected from query hits. You can enable this in the swarming section on the download config pane.
  • Download scheduling was entiretly redesigned to avoid hammering busy hosts and scale to 5000+ entries in the queue without slowing down the whole.
  • Is now smart about the "push" flag and will try to ignore it if possible, in case the remote host wrongly set the flag but is not firewalled.
  • gtk-gnutella now remembers the files it downloaded and will ignore further requests to download the same file. It will visually mark those files, as well as the ones it already shares, by showing them in lighter color in the search results.
  • It is possible to supply to gtk-gnutella your own ignore lists by SHA1 and by name/size but the feature is under-documented.
  • Added an "expert mode". Only when this is enabled will gtk-gnutella show the users some of the most complex settings.
  • New Gnutella statistics pane, showing the packets we sent and received, how many we generated, and the reasons why we drop packets, by packet type.
  • Now understands UTF-8 queries, but does not generate them.
  • Fixed important bugs whereby all earlier versions of gtk-gnutella were unintentionally corrupting the Gnutella traffic!
  • Moved away from the public hostcaches and now uses the Gnutella Web Cache.
  • Will now show all upload attempts, not only the ones that are transferring. If the connection is aborted, the reason is also shown.
  • New search stats types: queries by router, whole query.
    • "Queries by router" shows how many queries have been recieved from any node gtk-gnutella was directly connected to.
    • "Whole query" shows stats based on the complete query string instead of individual query words.
  • New visual indications via icons in the status bar: whether gtk-gnutella is rebuilding the library, computing SHA1 of shared files in the background, and whether we are connected to Internet or not.


  • When changing the directory for incomplete/complete files, all partially downloaded files recorded in ~/.gtk-gnutella/fileinfo will still be downloaded to the old directory. You need to manually change the paths in above file using search/replace and your favourite text editor.
  • Sorting order of tables is not perserved across sessions.
  • Marking/highlighting of results/downloads/uploads heavily depends on your GTK theme. Especially most themes do not set fg[ACTIVE] and fg[NORMAL] to different values.
  • There is currently no way to un-ignore a file via the gui. You can however edit the done.sha1 and done.namesize files in your ~/.gtk-gnutella directory manually. Unignoring via gui is planned for the next release.

We hope you will love this version. We still believe gtk-gnutella is the most advanced and efficient Gnutella servent available on Unix today.

07. July 2002, Version 0.90 stable released

Finally! After a fruitful beta testing, here is the real thing!

Besides the source code, you'll find on sourceforge pre-compiled packages in .deb and .rpm formats. Enjoy!

01. July 2002, Version 0.90 beta2 released

A bug-fixing and minor enhancement release, correcting small problems.

  • Greatly enhanced auto-selection in searches to use far less CPU.
  • Will now warn user when encountering a newer version of gtk-gnutella.
  • URN searches now supported, by typing "urn:sha1:" in search text, followed by the base32 value.

24. June 2002, Version 0.90 beta released

After nearly 3 months of development efforts, we are proud to present the new 0.90 beta version. It features many changes since the latest stable 0.85 release. Among them:

  • All configuration can now be made from the GUI.
  • Fully redesigned search filters to work like ipchains/iptable on Linux.
  • Obsoleted experimental "auto-download", superseded by the new filtering code.
  • Added Gnutella bandwidth management (0.85 already had HTTP bandwidth management, but it was not configurable via the GUI).
  • Both HTTP and Gnet bandwidth is now displayed real time.
  • Added full HUGE support (Hash/URN Gnutella Extensions).
  • Added support for local host preference.
  • gtk-gnutella can do traffic compression when connecting to a node that also supports it.
  • Upload and downloads will now show User-Agent/Server information.
  • Added status to the download queue.
  • You can now freeze the download queue whilst manipulating it.
  • Searches can now be listed on the left side of the screen, or as tabs like in the previous versions.
  • Added automatic banning of servents that are hammering us.
  • Many more cool new features that you'll discover whilst playing with it.

We hope you will like this version. We believe gtk-gnutella is one of the most advanced and efficient Gnutella servent available on Unix today.

15. May 2002, Traffic compression in action

After some more bug-fixing we now have a better working traffic compression and even some added stats. The percentages in the first row say 0% for 'no gain' and 100% for 'no traffic generated'.

Traffic compression in the Gnet stats

11. May 2002, gtk-gnutella supports traffic compression

Today Raphael completed the first implementation of the gtk-gntuella traffic compression stack. The whole thing is brand new and compression is not yet tested very much and will still have it's edges. But the more people get the code from CVS and file bug reports, the faster it will be stable.

3. May 2002, gtk-gnutella searches persist

As of the current CVS version gtk-gnutella saves the searches to disk and restores them again at startup. Also there have been lots of changes to the gui layout and bandwidth management can be done while gtk-gntuella is running.

5. April 2002, Version 0.85 With Traffic Prioritization and GUI Changes

Some changes to the GUI, many changes in what's displayed in what way (search, upload statistics, servent names, instantaneous transfer rates, etc.) and the possibility to connect through http proxies. Automatically detects changes to local IP. And many more changes.

23. March 2002, Version 0.85-beta1 Is Out

gtk-gnutella 0.85-beta1 has been released. As I've written in last weeks news there are many changes which make it really worth upgrading.
A short note about beta and CVS releases: the developers are really cautious about not adding new bugs or instability to the program, so in general the current CVS version or a beta release are as stable as real releases. The only difference between CVS/beta releases and a normal release is that the feature list for the next release isn't complete, and that a release candidate must be tested before release to be really sure that there are no bugs and instabilities.

16. March 2002, gtk-gnutella with Configurable Bandwidth Use

Version 0.80 stable has been out quite a while now, and Raphael has continued development on the CVS version (0.85 unstable) and added or fixed many many features. It's really worth downloading current gtk-gnutella from CVS and giving it a try. One of the most important enhancements had been the inclusion of bandwidth management. GG can now be configured to not use more than x bytes/sec, this works really great over modem or slow DSL lines.
To configure bandwidth management you have to change the values for output_bandwidth and input_bandwidth in your ~/.gtk-gnutella/config file. I have mine set to 10240 and 40960, this still leaves some room on my 512/128kbit/sec line.

27. January 2002, 0.80-beta2 Released and new Screenshots on Homepage

0.80beta2 is a bugfix release without new features. Please download it, test it, and report all remaining bugs.
For those of you interested in how nice gtk-gnutella can look please see the new screenshots on our Screenshots section.

19. January 2002, 0.80-beta1 Released

There are many many changes (see last weeks news), including search result filtering, support of the 0.6 handshaking protocol and a reduction of the bandwidth used through the implementation of a new ping/pong method.
Once the remaining important changes are implemented we will release a 0.90 version, which means feature freeze! So please check back often, test the CVS development version and report all bugs you may find.

12. January 2002, Lots of Major Changes in CVS

Much of the underlying code has been changed and brought up to date with newer versions of the Gnutella protocol (e.g. 0.6 handshaking support), although the GUI still looks pretty the same as before. Everyone should try it out (see our Development page about CVS) in order to catch those hidden bugs.
It's planned to release a 1.0 version soon and then to begin working on a completely new core and GUI, with a total separation of the two parts which will allow for different GUIs (think kde, ncurses, etc.) to work with the gnutella core of gtk-gnutella.

4. December 2001, 0.18 released a while ago

But I wasn't able to update the homepage because I was offline (I still am, basically, because I've moved and my cablemodem provider hasn't updated my account yet). Anyway, as always you should have a look at our project page at SF to see what's new. And if you're subscribed to our mailing lists you here about new releases when they happen and not weeks later...

13. November 2001, New Website Online

Right now it's (apart from the design) mostly internal changes, making it easy to maintain, add news articles, etc. We'll add more content, links, screenshots etc. Please let me (maol - the webmaster) know what you miss and what you like!

5. November 2001, 0.18 Will be released soon

Since the bugging memory leak in the preview version (available in CVS) has been found, 0.18 will be released soon.

24. October 2001, 0.17 finally available

This release should noticeably decrease the CPU usage, especially for people sharing many files and/or connecting to many nodes. On a 466 Mhz PC, with 3600+ files shared and 7 node connections, the typical CPU used is under 2%.

3. October 2001, Released 0.16

Further cleaned codebase, more optimization in lots of places, fixed some obvious bugs.

10. September 2001
