14 June 2020, Version 1.2.0 Released

This is an evolution release, hence the minor version bump.

Several cases of bad input (from network) causing assertion failures were fixed. In particular, bad DHT response after a security token lookup or invalid G2 input streams were fatal.

There was also a critical bug, originating from a harmful code typo, which led gtk-gnutella to serve unvailable file chunks from partial files, as if they were available, resulting in unintended download corruption on the remote end!

Thanks to Laurent Gil's efforts, it is now possible to run gtk-gnutella from a Docker container. See https://github.com/angegar/gtk-gnutella-docker. Running within docker raised some issues about sbrk() and thread_self(), which were fixed.

The computation of the build date was fixed, to avoid corner cases where gtk-gnutella would complain it was "old" when freshely compiled from up-to-date sources in a git tree whose "master" branch was only infrequently updated.

The file selector was fixed, to avoid displaying grayed-out folders, a setup wich did not allow one to actually select directories in the preferences.

Many improvements were done to allow smoother uploading for servents with more bandwidth than the recipients. Instead of drastically limiting upload bandwidth (which was negatively impacting everyone), we are now monitoring and adjusting our uploading speed to avoid congestion on the remote end. When stalling happens, we also react quickly to reduce the available bandwidth of the connection, not that of all connections to whom we are uploading.

We also no longer rely on MaxMind GeoIP for providing the IP -> country mappings. Their distribution mode now requires a specific licence which seems totally incompatible with the gtk-gnutella's distribution mode. Instead, we are now using IP2Location, and the GEO_LICENCE file now lists the conditions under which these data are re-distributed (gtk-gnutella transforms the data into a form that it can digest, so we are distributing a modified, derived work, not the original).

If you are still using a version of gtk-gnutella earlier than the 1.1.x series, you are strongly encouraged to upgrade. Starting from this release, we are now considering these versions too old to connect to.

14 July 2019, Version 1.1.15 Released

This release is a maintenance one fixing several minor bugs and two annoying

ones

• The semi-reliable UDP layer could crash due to an assertion that started to trigger with the introduction of an explicit flush before the message times out for transmission.
• Due to an overseen condition, we were not able to serve seeded files when Partial File Sharing is enabled. A seeded file is a completed file that still lies in the downloaded directory but is not part of the library directories.

The OOB banning code for hosts that never claim their OOB hits was also revisited to prevent problems with hosts that query a popular file and then get submerged by hits and thus refrain to claim the additional hits. We are now much more tolerant to avoid accidentally banning innocent hosts.

On Windows, the disassembling of machine instructions was enhanced to further improve the ability to correctly issue symbolic stack traces when encountering assertion failures or during crashes.

Finally, the Geo IP databases were refreshed.

Improvements

• OOB: increased timeout for OOB hit delivery.
• OOB: switch to unreliable notification if semi-reliable UDP fails.
• OOB: raise the bar for banning after unclaimed OOB hits.
• Dynamic Hits: let us forward hits that bear a small amount of results.
• Count amount of banning we have to do for OOB querying hosts.

Bug Fixes

4 October 2018, Version 1.1.14 Released

This release mostly improves the core routines and fixes a few important bugs.

Due to a bug in the usage of the RX buffers, we were not correctly parsing data returned in "chunked" transfer-encoding by HTTP/1.1 servers. This affected the UPnP logic.

The UPnP port unmapping done when the program shuts down was also not being able to complete successfully because we were preventing the HTTP connection from going on during the shutdown. Not critical because there is a lifetime attached to all mappings, but always best to properly clean-up when leaving.

The algorithm used to pick random chunks to download was also revisited to ensure a uniform selection within the whole file ranges that remain to be fetched.

At startup time, the DHT code no longer expires keys when reloading data. This could create crashes during the operation, with no other remedy than to erase all the DHT database files manually to be able to recover!

The background task layer was also causing crashes (at exit time though) because it was not recording whether it was running "user" code as opposed to "kernel" code.

The SDBM code was also improved to allow concurrency and, in particular, a "loose" iteration scheme which does not need to grab the database lock during the whole iteration process. It is also possible to perform a concurrent database rebuilding.

The thread runtime now has an improved deadlock detection engine, based on a topological sort, that can definitely tell whether we are deadlocked. When the deadlock is detected, we can also have more information about the threads participating in that deadlock condition, to assist debugging.

On Windows, a bug in our mingw_dlerror() emulation caused it to always fail once an error had been recorded, leading to un-decorated subsequent stack traces, which really do not help on that platform!

There was also a concurrency bug in the processing of network queries. Every time the library was rescanned, it could trigger a crash due to a memory zone being declared private and was in fact shared between threads. The crash occurred only when a query was received on the Gnutella network whilst the library was rescanned.

The semi-reliable UDP layer TX side was revisited to maximize chances that reliable messages get through completely.

The pattern matching code was revisited thoroughly. A new algorithm (2-Way String Matching) now complements the Quick Search algorithm and an initial benchmarking is done to compare our own matching routines with native libc versions of strstr(), strlen(), strchr() and memchr(). The fastest routine is then selected, to ensure optimal performances. There is also a unit-test program ensuring proper semantics for the pattern search flags.

22 October 2017, Version 1.1.13 Released

This release primarily addresses issues that were left-over in 1.1.12. Do not use that previous release, migrate from 1.1.11 to 1.1.13 directly!

The main issue was that of Partial File Sharing. Numerous bugs, dating from 7 years or more, were lurking because my local configuration had switched PFS off for testing, and it had never been turned back on! In particular, completed files were not properly shared, it was not possible to upload their THEX since it was not recomputed, and the files were not properly indexed in the Query Routing Table due to bugs in the background task layer.

In case of a crash, we now dump the value of all the Gnutella properties to be able to spot configurations that deviate from the norm. Too many bugs were reported and ignored because they could not be reproduced, often due to not having the same setup when attempting to debug!

Another nasty bug was fixed: it was not possible to change the IP support configuration without causing an immediate crash. The reason is due to a change that was integrated in 1.1.12 to allow IPv6 UDP traffic from G2 nodes. The problem was that this created an extra client stack on top of the low-level UDP traffic scheduler and it was not properly cleaned-up when switching IP configurations, leading to an assertion failure!

11 November 2016, Version 1.1.11 Released

This release fixes a portability issue on FreeBSD and introduces a main core feature and minor new GUI features.

The main feature is the addition of "equivalence classes" defining word aliases, used when sharing files and querying for them.

Currently, the only supported equivalence class deals with naming of series. Indeed, there are various conventions that can be used to represent these, and it makes searching inefficient: either one will lookup for all the possible variations, or one will miss some of the files.

For instance, episode #8 of an hypothetical season #4 can be represented by any of these strings:

	{ "s04e08", "4x08", "408", "04x08", "0408" }

Thanks to the equivalence class, a file bearing one of these strings can be searched for (and located successfully) by using any of the other strings. Of course, since this is a local processing, the more servents out there are deployed with this aliasing support, the more efficient the feature becomes!

There are also new GUI features: the "Clear completed" button from the Download pane is now doing someething useful, and the current page of different notebooks is remembered across sessions. The only one which is not restored on normal resuming is the main notebook tab. It will be restored if GTKG is restarted after a crash, but otherwise the application will always start up within the Network tab.

In the Uploads tab, upload requests coming from a G2 servent will now be flagged with a "[G2]" tab right after the IP address. This helps seeing how the Gnutella and G2 network unification is evolving.

New Features

• Flag uploads coming from G2 servents with a "[G2]" tag after IP address.
• Added alias support in sharing/querying.
• Made the "Clear completed" button in Downloads/Tools do something useful.
• Moved "Clear completed" button to the bottom right of the download pane.
• Remember fileinfo notebook tab number across sessions.
• Remember main notebook tab number across sessions, only restored after crash.
• Remember Gnet stats notebook tab number across sessions.
• Remember download info / tools notebook tab number across sessions.

Improvements

• Added --cleanup to explicitly request for final memory cleanup sequence.
• Updated Italian translation.
• Updated GeoIP databases.

Bug Fixes

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.

Improvements

• [GTK2] Added menu to display the new glossary window.

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.

Improvements

• 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.

• VMM: added new flag to signal OOM condition and be aggressive with the cache.

• Make sure we don't restart nor pause a failing process on --shell or --ping.

8 November 2015, Version 1.1.6 Released

This is a bug-fixing release.

This time it focues on Windows, which apparently exercised some bugs in common code with other platforms -- so some fixes are going to benefit to everyone even though the bugs did not manifest themselves as often.

Improvements

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).

Improvements

• UHC: re-engineered the random choice of UHCs in the pre-established list.

• 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.

Improvements

• [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.

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!

Improvements

• [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 FAQ along with French and Turkish translations.
• 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.
• rwlock_destroy(): make sure to write-unlock the lock if it was owned.
• waiter_ack(): don't panic if waiter was not notified, but loudly complain.
• upnp_map_natpmp_publish_reply(): trace given port on NAT-PMP mapping errors.
• upnp_discover(): force selection of IPv4 interface for UPnP discovery.
• thread_unsuspend_others(): relaxed hard assertion into a soft one.

• socket_connect_finalize(): fixed wrong errno processing for connect().
• socket_connect_prepare(): no need for SO_REUSEADDR for connecting sockets.

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.

Improvements

• [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.
• FAQ: added new entry explaining how to get the magnet of a shared file.

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.

New Features

31 December 2013, Version 1.0.1 Released

This is a minor release correcting a grave bug causing gtk-gnutella to think all other gtk-gnutella out there are hostile.

Other minor improvements are present, as well as low-level bug fixes. The most visible change is that filenames with parentheses are now mangled to have the parentheses turned into brackets, instead of being left as-is.

1 September 2013, Version 1.0.0 Released

This is a major release correcting a few bugs and adding small but interesting features such as the ability to limit dropping of received UDP messages, making the DHT keys and values persistent across sessions, SDBM file auto-compaction at startup, and last but not least, rarest-chunk downloading to optimize download efficiency when facing partial sources.

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.

New Features

• Plugged support for "OOB Proxy Veto".
• Added a Semi-Reliable UDP layer for Gnutella for safe OOB hit delivery.
• Report and display available file size when handling hits for partial files.

• 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.

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].

• Make sure we remove the SHA1 of de-indexed files from the shared set.
• Handle "message too large" errors when sending on UDP.

Under the Hood

• When running as ultra node, use GUESS introduction pings when requesting a query key so that the remote ultrapeer can passively discover us.
• Do not count GUID collisions with our own GUID when we see our own IP:port!
• Added some gcc 4.6 hot / cold routine tagging for better optimizations.
• netmask_to_cidr(): was not using the proper metaconfig symbol to activate the usage of __builtin_popcount.
• Updated build.sh to build an app bundle for OSX with target=osxbundle.
• Added dmg to the default extension list for shared files.

• 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.

Improvements

• 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.

Miscellaneous

• 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 build.sh: 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.

Gtk-Gnutella is

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.

Limitations

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.

Improvements

• 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.

Limitations

• 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.

Improvements

• 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 2.1.0.0).
• 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.

Limitations

• 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.

gtk-gnutella チーム

2005年5月6日, バージョン 0.95.1 がリリースされました

バージョン 0.95.1 は安定版としてリリースされます。0.95 以前と比べて安定性が飛躍的に向上しましたので、0.95 で何らかの問題を抱えていたのなら、それらはこのバージョンで恐らく解消されているでしょう。この新しいバージョンへのアップグレードを推奨します。

• これより、Bitzi チケットは gtk-gnutella を再起動した後でも利用できるよう、永続的にキャッシュされます。
• ユニコード・サポートの改良:
  • 検索式 (クエリー) で使用されるユニコードは、他の Gnutella クライアントのユニコード・ファイル名にマッチします。これである種の非ラテン文字を含むファイル名の検索が容易になります。このリリースの時点で、gtk-gnutella 0.95.1 と LimeWire のみがユニコード検索式 (クエリー) に対して適切に応答します。
  • ファイル名は UTF-8 に変換されて共有されます、ダウンロードされたものも UTF-8 ファイル名で保管されます。
  • 今回、ユニコードサポートは内部に組み込まれましたので、もう ICU ライブラリに依存しません。
• 検索の改良:
  • 検索に使用する文字列にマイナス記号を付けることで、その文字列を含む検索結果を除外できます。例えば、検索文字列に "blah -blubb -nada" を使用した場合、"blubb" または "nada" に一致するものは自動的に除外されます。
  • 検索フィルターは 4 ギガバイト以上のファイルをフィルターできるようになります。また、サイズの入力の際に KB, KiB, MB, MiB 他のような接尾辞も使えます。
• [GTK2] GUI の更新:
  • "ダウンロード->ファイル" にあるアイテムをドラッグ＆ドロップできます。例えばこれらをオーディオ/ビデオプレイヤーや画像ビューア他に渡せます。ですが、不明な送信元からのファイルをドラッグ＆ドロップするのは危険ですのでよく覚えておいて下さい。
  • GnutellaNet のコンテキストメニューに、ピアの IP アドレスを調べるための "DNS の逆引き検索" という項目が新たに加わりました。
  • 検索結果に含まれる XML データはその詳細情報ペインで表示されます。
  • 検索文を入力する場所が上部に移されました。
  • ダウンロードペインが "稼働中の送信元" と "キュー" に分割されました。
  • GTK 2.6.x とそれより古いバージョンとで互換性があります。
• GUI は IEC 60027-2 (2000-11) Ed. 2.0 に基づく SI プリフィックスをあらゆる場所で使用します。従ってこれ以上ハードディスク・ベンダに騙されることはありません。
• 64 ビット・アーキテクチャを含む更なるアーキテクチャでコンパイルできるよう、互換性の問題が修正されました。
  • largefile に互換性のない sendfile() を持つシステムでも再び動作します。sendfile() がないプラットフォームでは、効率を上げるために mmap() を使用します。
• 今回から、二つの hostiles.txt が存在することになります、システム全般 ("グローバル") に影響するものと ~/.gtk-gnutella フォルダに置かれる個人用のものです。これらのファイルは変更が有り次第自動的にリロードされますので、変更を有効にするために gtk-gnutella を再起動する必要はありません。
• 地理情報、偽のアドレスおよびスパムサイトのリストが更新されました。
• 数多くのバグが修正されましたので 0.95 と比較した場合、安定性が大幅に増しています。そのほか修正された特筆すべきバグは:
  • アップロードができなくなっていた場合、ウルトラピアとしての gtk-gnutella がいかなる検索もルーティングしていませんでした。
  • UDP/TCP ポート設定での問題が修正されました (バグ #1091827)。
• ドイツ語、日本語およびスペイン語の翻訳が更新されました。

2004年11月27日, バージョン 0.95 がリリースされました

今回のバージョン 0.95 のリリースに伴い、gtk-gnutella は Gnutella ネットワークの最先端の機能をサポートします。 Gnutella の機能にてらせば、バージョン 0.94 は推奨できないサーバントと考えられます。ネットワークが持つ性能を引き出すために、 またネットワークを健全な状態に保つためにも、すべての gtk-gnutella 利用者はできるだけ早く 0.95 にアップグレードする必要があります。

• GUI の更新:
  • マグネットリンクへのドラッグ＆ドロップが可能になりました。
  • [GTK1] 検索結果の表示欄が減らされます、ヒットの詳細は下に隠れている分割されたペインで表示されるようになります。
  • グラフ表示される進捗インジケーターが新しくダウンロードされる部分、現在ダウンロード可能な部分をより正確に表示します、また実際にダウンロードしている箇所を矢印で指します。
  • 検索結果の最大数が 1000 に引き下げられます。多くの検索結果を受け取ってしまうなら、お望みのファイルを検索するためにはフィルター、あるいはもっと絞った検索式 (クエリー) を入力して下さい。
  • 検索結果の利用可能なすべての情報を表示するため、"ファイルに関する情報" という項目が検索結果ペインに加えられています。
  • ステータスバーがコンタクトの取れたホストキャッシュに関するフィードバックを表示します。
  • Gnutella ノード・ステータスがどれくらいのバイト数を送信/受信したのかを表示するようになります。
  • ノードペインでは、検索ペインのように、どの欄を表示するかを右クリックで現れるメニューから設定できます。
  • さらに多くの一般統計がステータスペインに追加されました。TCP と/または UDP トラフィックのステータスを別けて見られます (メッセージのみです、フロー制御は見られません)。
• ダウンロード可能なファイルの評価情報を取得するため、Bitzi サポートが追加されています。詳細は http://bitzi.com/ を御覧下さい。
• MaxMind の好意により、ホストの地理情報が表示されるようになりました。
• 最近開発された Gnutella ネットワークの機能がサポートされました:
  • 高い出次数 (OutDegree) により Gnutella ホスト間の接続性が向上しています。今回ネットワークの最大 TTL (パケットの有効時間) は 4 に、ウルトラノードは最低でも 30 基のピアと接続を維持する必要があります。
  • ウルトラピア間の Last-hop QRP (問合わせルート設定プロトコル) がサポートされました。
  • 動的な問合わせがサポートされましたので、単にクエリーを広域送信する代わりに、ピアの問合わせを選択的に行えます。これはリーフノードのクエリーおよび、ウルトラノードとして動作している時のあなたのクエリーに対して使用されます。
  • 帯域外 (Out-Of-Band) クエリーヒットにより、他のサーバントは Gnutella ネットワークを経由させずに、直接あなたに検索結果を届けられます。
  • OOB のプロキシ経由のクエリーを利用することで、レガシーリーフノードが発したクエリーへのヒットを、ウルトラノードのレベルで直接届けることが可能になります。
  • ファイアウォール内にあるホストは、ウルトラノードになれないようになります。
  • "自動設定" モードで実行している場合、アップロードが異常に速い送信速度で滞っていたり、帯域幅が飽和していることを示しているなら、gtk-gnutella はリーフモードに戻されます。
• TCP に加えて UDP も転送プロトコルとしてサポートされます。この機能を最大限活用するために、ファイアウォールの設定を変更する必要があるかもしれません。この UDP ポートは TCP に使用されるポートと同じものを使用します。
• ファイアウォールの検出が UDP の検出も含めて改良されています。
• NTP が走っていないホストでの時計のずれを算出する方法が再設計されています。 また gtk-gnutella はローカルホストで走っている NTP を自動的に検出するようになります。
• 2 ギガバイト以上のファイルも使えるよう、巨大ファイルへのサポートが加えられています。
• 日本語訳が加わりました。
• フランス語とドイツ語の翻訳が更新されました。

バージョン 0.93.4 のリリースで 0.93 ブランチは安定性が改善されている一方、リリース 0.94 にはいくつかの素晴らしい新機能が追加されました、とは言え 0.93.4 と同じくらい安定しているはずです:

• GUI が更新されました:
  • ファイル情報ペインは "ダウンロード" に名前変更されました。
  • ダウンロード・ペインは "送信元" に名前変更されました。
  • ダウンロードの途中経過が視覚的に表示されます。すでにダウンロードされているファイルの部分、今現在ダウンロードしている部分および Gnutella ネットワーク上にあるダウンロード可能な部分が表示されます。
  • アップロードとダウンロード送信元ペインも視覚的な進捗バーを表示します。
  • GTK2 の GUI の横幅が 933 ピクセルよりも狭くできるようになりました。
  • 検索結果の表示欄に拡張子も表示されますので、必要ならファイルの拡張子による並べ替えもできます。
  • Gnet ステータス・パネルとステータスバーが水平分布統計を表示します。
• 新しい Gnutella の拡張規格 HSEP/0.2 が組み込まれました。これは水平サイズの推定量を提示します。到達可能なノードやファイルの数、ネットワーク上に存在するすべてのファイルの合計サイズが表示されます。
• リモートシェルにコマンド "HORIZON" が加えられました、これは (パケットの) 到達領域ステータスを出力します。
• 標準ポートが指定されない場合は、無作為に選んで使用し続けます。
  ファイアウォールの内側にいて gtk-gnutella にポートをルーティングさせているなら、まだそのポートを使用しているか確認して下さい!
• ブートストラップする gwebcache リプライから最大 150 基までのホストを解析するようになります。
• gtk-gnutella は新しいホストキャッシュでより素早くネットワークに接続します。
• オランダ語の翻訳が更新されました。

2003年7月20日, バージョン 0.92.1 の候補がリリースされました

一・二週間で、とても安定しているバージョン 0.92.1 を提供できるよう、この候補をテストして下さい。これはリリース版と同じ位にあんていしていて、素晴らしいものになっているはずです。ツール一連にいくつかの問題があるので、ソースのみのリリースとなります。

貢献して下さった方やバグを報告して下さった方すべてに感謝します!

gtk-gnutella チーム

2003年6月15日, バージョン 0.92 がリリースされました

ダウンロード・セクションからこの新しいバージョンを入手できます。ここに上げるのは最新の安定版リリース 0.91.1 以降のいくつかの変更です:

• gtk-gnutella がウルトラピアになれるようになりました。
• クライアント側で PFSP (部分ファイル共有) をサポートしました。
• 完全な PARQ (Passive / Active Remote Queuing) サポートが追加されました。
• ネットワークにより素早く接続するようになり、帯域幅の利用法が改良されました。
• 非同期 DNS 検索をサポートしました。

さらなる変更はここにあります。

gtk-gnutella チーム

2003年5月25日, バージョン 0.92 の候補がリリースされました

• 今回 PARQ は完全に実装されています。
• 敵対的な IP アドレスを除外するようになります。
• ノードの状態 (リーフまたはウルトラモード) を示す新しいアイコンが表示されます。
• ダウンロード画面に "ファイル情報" ペインが新しく追加されました。完成はしていませんが、現在ダウンロードに登録しているものと、そのステータスを表示するようになります。
• 細かいバグが修正されました。
• GTK2 版は検索ペインで同じファイルを一つのグループにまとめます。

警告: ウルトラモードで動作している場合、リーフノードの帯域幅は HTTP から取られます。これで外への HTTP 帯域幅が 0 になるようなら、共有は無効になってしまいます。

gtk-gnutella チーム

2003年3月3日, バージョン 0.92 beta2 がリリースされました

これはバグ修正リリースです。beta1 を使用しているなら、このβ版にアップグレードして下さい。今のところ大半の利用者にとって GTK2 は遅すぎるため、GTK1 にのみコンパイル済みのものがあります。

• Gnutella ウェブ・キャッシュを頻繁に見に行っていまうバグが修正されました。 あるバグのようなテストのせいで、gtk-gnutella が毎回キャッシュに問い合わせていました。外部への接続を確立してしまっていたのです!
• Gnutella ウェブ・キャッシュのドメイン名解決が非同期的に行われるようになります。 もう GUI が DNS リクエストで固まってしまう事はありません。
• 一部性能の向上: 最も重大なボトルネックが取り除かれました。
• フロー制御のバグが修正されました、これは主に圧縮接続に影響を及ぼしていました: 不意に立往生したり、データを伝達しなくなってしまう可能性がありました。
• PARQ クライアントコードでのアサーション失敗が修正されました。
• ある指定されたホストからのダウンロードファイルの消去が不完全なのを修正しました。
• 警告: 現在のところ "余剰帯域幅を使う" が有効になっているかどうかに関わらず、リーフモードでない場合には各リーフノードに設定された帯域幅の合計は HTTP 接続に追加されます。これは後のリリースで変更されます。

gtk-gnutella チーム

2003年2月9日, 0.92 β版のコンパイルに問題が?

パッケージの GTK2 版をコンパイルするのに問題を抱えているのでしたら、GTK1 の方を選ぶか CVS からコンパイルしてみて下さい。どういうわけか、パケットが壊れているようです :(
このことに関して調査するつもりです。

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

2003年2月8日, バージョン 0.92 βがリリースされました

私達はここに自信を持って今度の 0.92 リリースのβ版をリリースします。多くの特徴的な変更がなされていますので、できるだけ広い範囲に渡ってテストして下さるようお願いします。見つかったバグはどのようなものでも IRC チャンネルかメーリングリストに報告して下さい :)

• 今回からウルトラピアをサポートします、つまり gtk-gnutella はウルトラノードあるいはリーフノードとして動作することになります。まだノーマルノードとして動作することができますが、これは賢いやり方とは言えません、なぜならそれはあなたを Gnutella ネットワークの極一部に押しやってしまう恐れがあるからです。
• GTK2 フロントエンドは、たとえ GTK1 より遅くとも、もう試作ではありません。速度の問題は基礎をなす GTK ライブラリの実装がやや非効率なことに起因します。1 GHz のインテルチップに匹敵する CPU が搭載されていない場合は GTK2 を使用しないで下さい。
• クライアント側での PFSP (部分ファイル共有) サポートが追加されました。gtk-gnutella は部分ファイルを持っているサーバからダウンロードできるようになります。
• クライアント側での PARQ サポート (受動/能動遠隔キューイング) が追加されました。gtk-gnutella は能動キューイング・サーバまたは PARQ のどちらかからダウンロードを待機列に入れられるようになります。
• 新しい Gnet 統計: TTL およびホップ毎のフロー制御されたパケットを表示します。
• Gnet 接続ペインの "種類" 欄は "フラグ" になりました。
• Ping/Pong/Push での GGEP サポートが追加されました: 受け付けられたこれらのパケットは、GGEP をサポートしている事を知らせながら接続ホストに回送されます。
• 新しい設定 "余剰帯域幅を利用する": もし必要とされる場合、Gnet または HTTP で使用されないすべての帯域幅は他に回されます。
• アップロードおよびダウンロードされた合計バイト数の総計が追加されました。
• ベンダ特定メッセージのサポートが追加されました。
• 非ノーマルモードで動作している時、もう設定 "圧縮転送を優先する" は意図した通りに働きません。
• 新しいホップ-フロー・サポート: 今回より、フロー制御された遠隔接続は、こちらのフローを制御している事を警告するようになります。従ってこちらはそれらに送信する代わりに、外部への帯域幅を節約しながら、即座にクエリを破棄できるようになります。
• 検索式 (クエリ) ヒットにおいて gtk-gnutella のバージョンを表示するようになります。
• キューペインはキュー (待機中のダウンロード) の総計と同様に有効なダウンロードの総計も表示します。"有効" ダウンロード・ペインは遠隔サーバが応答するダウンロードが表示されるエントリーです。
• 接続アルゴリズムが変更されました: これにより実際に設定されたものより多くの接続を試みるて、必要になった場合に、後で余分な接続を破棄するようになります。

追伸: Raphael が楽しい空の旅と DMCA の地での滞在を送れますように ;)

2003年1月27日, まだ活動しています

これは gtk-gnutella がまだ開発されている事をお知らせするささやかな情報です。現在 CVS にはウルトラピア側およびリーフ側でのウルトラピアサポートが加えられています。クライアント側の部分ファイル共有プロトコル (PFSP) も追加されています。同様に誰か (MrJoe ;) がキューイングサポートを実装しています。素晴らしいニュースだと思いませんか? :)
Bleeding Edge 版を試してみたければ、開発に関するページへ行ってどのように CVS 版を入手するか見てみて下さい。

2002年12月24日, メリークリスマス

gtk-gnutella チームはこの世の全ての人に楽しく幸福なクリスマスが訪れることを願っています! もし Gnutella ネットワークに何かお返ししたいと思うなら、GWebCache (それと、もちろん gtk-gnutella) を走らせて支援して下さい ;-)

2002年11月25日, ウェブページの新しい管理者から

こんにちは皆さん、
私は gtk-gnutella ウェブページの新しい管理者です。もっと多くの情報を載せて利用者が私達を訪れる手助けをしたいと思っています :) 何か質問や加えたいものがあれば気軽にメールして下さい。
依然として私達はもっと多くの開発者を必要としている事を忘れずにいて下さい!

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

2002年11月22日, 0.91.1 安定版がリリースされました

細かいバグの修正リリースです、これにはバージョン 0.92u ではすでに追加されている、動作する新しい機能すべても含まれています。

• ダウンロードされたファイルの SHA1 を見えない所で検証するようになります。
• フォルダを設定する新しいパラメータが追加されます、このフォルダがある場所に知らされた SHA1 とは一致しない "不正ファイル" が置かれます (標準では /tmp になりますので、設定するのを忘れないで下さい)。
• 異なるファイルシステム上にある様々な "ダウンロード" フォルダをセットアップするのが可能になるように、今回から見えない所でファイルがコピーされます。
• ノード接続時間および遠隔ノードの稼働時間が (可能であれば) 表示されます。
• SHA1 検索を始めるため検索語入力フォームに "magnet:" URI を貼り付けられます。
• 左下にある "接続インジケータ" が切り替え可能になります。接続を切ると、アップロードの提供およびダウンロードの処理を除くあらゆる Gnet 接続が終了するでしょう。
• 実行中のダウンロードのステータスがどれくらいの数の送信元を利用できて、どれくらいの数が現在有効 (すなわちダウンロード中) かを表示します。同様に、詳細な報告をしながら、ファイル全体がダウンロードされるまでのおおよその残り時間も表示します。
• ファイルの SHA1 が分かっている場合に、最近の BearShare (4.1.x またはそれ以降) および Shareaza (1.6.0 またはそれ以降) からきちんとダウンロードできなくなるバグが修正されました。
• 関連する IP を禁止することで "大量に来る PUSH" に対して保護処置を取るようになります。
• 起動時に、ダウンロード完了したファイル (その SHA1 が問題ないと確認されたかによります) を関連フォルダに移動しながら、置去りにされているファイルをダウンロードの "tmp" フォルダでスキャンして、それらをファイル情報データベースで再統合します。
• 細かなバグの修正: 一時退避する時の Push のタイムアウトに対する秒読み時期が不適当でした、クラッシュや不正確な振る舞いを引き起こす可能性のあるコーナー・ケース処理が修正されました、X-Live-Since ヘッダで偶発的なローカル化が起こっていました、多数のアップロードをクリアする時に GUI が固まってしまっていました、不明瞭な移植性が修正されました。

できるだけ早くアップグレードすることを強く勧めます。

Raphaël Manfredi & Richard Eckart

2002年10月19日, 0.91 安定版がリリースされました

ほぼ三ヶ月に及ぶ開発努力の後に、この新しい 0.91 安定版を自身を持って発表します。最新の 0.90 リリース以降、数多くの特徴をなす変更がなされています。とりわけ:

• HTTP/1.1 を使用します、これは言外に永続的な接続をサポートすることを示唆します。
• インターネットに繋がっているか監視して接続の調子が悪ければ (長くて三分の遅れを検出後)、その接続リクエストを減らすようになります。
• 多数の送信元からのダウンロード (Swarming) がサポートされます: gtk-gnutella は別の送信元が利用可能な限り、同一ファイルの異なる一部を多くのホストからダウンロードするようになります。
• ダウンロード・キューをもっと多くの送信元で埋めるように、今回からダウンロード・メッシュ (ダウンロード中に別の送信元を収集) が使用されます。
• 検索式 (クエリ) ヒットから別にダウンロード可能な場所を受動的に収集するようになります。 ダウンロード設定ペインの多元ダウンロード (Swarming) を設定する場所でこれを有効にできます。
• 使用中のホストへの頻繁なアクセス (Hammering) を避けるために、また全体を減速させることなくキューにおいて 5000 以上の規模のエントリーを扱えるよう、ダウンロードのスケジュール処理が全面的に再設計されました。
• 今回より "Push" フラグを備えるようになります。もしファイアウォール内にない遠隔ホストがこのフラグを誤ってセットした場合、可能であれば無視するよう試みるでしょう。
• ダウンロードされたファイルを覚えておいて、同じファイルをダウンロードする更なるリクエストを無視するようになります。 検索結果においてより明るい色で表示することで、すでに共有しているファイルと同様に、これらにも視覚的なマークを付けるようになります。
• gtk-gnutella にあなた自身が作成した "SHA1" および "名前/大きさ" による無視ファイルリストを渡せるようになります。ですが、この機能に関する文書は作成中です。
• "上級者モード" が追加されました。これが有効になっている時のみ利用者に一部の最も複雑な設定を表示します。
• 新しい Gnutella 統計ペインで、パケットの種類に応じて、送信および受信した数、こちらで生成した数、こちらで破棄した理由を表示します。
• UTF-8 のクエリを理解するようになりますが、生成はしません。
• 重要なバグが修正されています、それによって初期のバージョンのすべての gtk-gnutella が、故意ではないのですが Gnutella トラフィックを悪化させていました!
• 一般公開されているホストキャッシュを使わずに Gnutella ウェブキャッシュ (GWebCache) を使用するようになります。
• 転送中のものだけでなく、すべてのアップロード要求を表示します。接続が中断された場合でもその理由が表示されます。
• 新しい種類の検索ステータス: ルータによるクエリ、クエリ全体。
  • "ルータによるクエリ" はどれくらいの数のクエリを gtk-gnutella に直接接続しているいずれかのノードから受け取っているかを表示します。
  • "クエリ全体" は別個の検索語の代わりに完全な検索文字列を基にしたステータスを表示します。
• 新しくステータスバーにアイコンで視覚的な表示を行います: gtk-gnutella がライブラリを再構築しているかどうか、見えない所で共有ファイルの SHA1 を算出しているかどうか、それとインターネットに接続しているかどうかが分かるようになります。

判明しているバグ/問題:

• 不完全/完全なファイルを置くフォルダを変更しても、~/.gtk-gnutela/fileinfo に記録されている部分的にダウンロードされるファイルは依然として元のフォルダにダウンロードされます。あなたはお好きなエディタの検索/置換を利用してこのファイルの各ファイルのパスを変更する必要があります。
• 各テーブルの並び順はセッションに跨って保存されません。
• 検索結果/ダウンロード/アップロードのマーキング/強調表示はあなたの GTK テーマにかなり依存します。特にほとんどのテーマは fg[ACTIVE] と fg[NORMAL] に違う値を設定していません。
• 今のところ無視されるファイルを GUI 経由で再び戻す方法はありません。しかしながら、~/.gtk-gnutella フォルダにあるファイル done.sha1 と done.namesize を御自分の手で編集することができます。次のリリースで GUI を通して行えるよう、予定されています。

このバージョンを本当に気に入って下さることを願っています。私達は gtk-gnutella が今日 Unix で利用可能な最も高度で機能的な Gnutella サーバントだと依然考えています。

Raphaël Manfredi & Richard Eckart

2002年7月7日, バージョン 0.90 安定版がリリースされました

とうとうリリースされました! 実り多いβテストの後、実際のものがここにあります!

ソースコードに加えて、コンパイル済みの .deb および .rpm 形式パッケージが SourceForge にあります。楽しんで下さい!

2002年7月1日, バージョン 0.90 beta2 がリリースされました

ささいな問題を直しつつ、バグ修正および細かい拡張がなされたリリースです。

• CPU の使用率がずっと少なくなるよう、検索での自動選択が非常に高度なものになりました。
• より新しいバージョンの gtk-gnutella に出会った時に利用者に注意を促すようになりました。
• 検索語に "urn:sha1:" と入力してその後に Base32 値を続けることで、URN 検索ができるようになります。

Raphaël Manfredi & Richard Eckart

2002年6月24日, バージョン 0.90 βがリリースされました

ほぼ三ヶ月にも及ぶ弛まない開発の後、自信を持って新しい 0.90 β版を発表します。最新の安定版 0.85 以降、多くの特徴をなす変更が行われています。とりわけ:

• すべての設定は GUI から行えるようになっています。
• Linux の ipchains/iptable のように働くよう、検索フィルターが全面的に再設計されています。
• 試作だった "自動ダウンロード" が廃止され、新しいフィルター処理コードに取り代えられています。
• Gnutella 帯域幅を管理できるようになっています (0.85 ではすでに HTTP 帯域幅を管理できましたが、GUI 経由では設定できませんでした)。
• HTTP および Gnet の帯域幅はリアルタイムに表示されます。
• 完全な HUGE (Hash/URN Gnutella Extensions) サポートが追加されました。
• ローカルホストの環境設定が追加されました。
• 圧縮トラフィックをサポートしているノードに接続する際には gtk-gnutella もそれを行えます。
• アップロードおよびダウンロードではユーザ・エージェント/サーバ情報が表示されるようになります。
• ダウンロード・キューのステータスが追加されました。
• ダウンロード・キューを手動で凍結できるようになります。
• 検索はウィンドウの左側にリスト表示されるか、以前のバージョンのようにタブとして表示されます。
• 頻繁にアクセスしてくる (hammering) サーバントを自動的に禁止します。
• 多くのカッコよい新機能が追加されました、それらはいろいろ試しているうちに発見するでしょう。

このバージョンを気に入って下さることを願っています。私達は gtk-gnutella が今日 Unix で利用可能な最も高度で機能的な Gnutella サーバントの一つだと考えています。

Raphaël Manfredi & Richard Eckart

2002年5月15日, トラフィック圧縮が活動中

いくつかのバグ修正後、トラフィック圧縮が良好に働くようになりました。いくつかのステータスさえ追加されています。最初の行にある割合 (TXc=...,62% RXc=...,39%) で、0% というのは '増加なし' を 100% は '発生トラフィックなし' を表します。

2002年5月11日, gtk-gnutella は圧縮トラフィックをサポートします

本日 Raphael は gtk-gnutella トラフィック圧縮スタックの最初の実装を完成させました。何から何まで新しく圧縮は依然として十分にテストされていませんので、まだ角が残っています。しかし、多くの人が CVS からコードを入手してバグを報告して下されば下さるほど、早く安定することになるでしょう。

2002年5月3日, gtk-gnutella は検索を保存します

現在の CVS 版の gtk-gnutella では、検索語をディスクに保存して再起動時に復元するようになっています。 GUI のレイアウトも大きく変更されていて、帯域幅の管理は gtk-gnutella の実行中に行えます。

2002年4月5日, バージョン 0.85 ではトラフィックの優先順位付けられるようになり GUI が変更されています

GUI が一部変更されています、表示されるものとその表示のされ方 (検索、アップロード統計、サーバント名、瞬間転送速度、他) が大きく変更されています。また HTTP プロキシを通して接続できるようになります。ローカル IP の変更も自動的に検出します。他多くの変更がなされました。

2002年3月23日, バージョン 0.85-beta1 が出ています

gtk-gnutella 0.85-beta1 がリリースされています。先週のニュースに書いたように、 多くの変更 がなされていますので、アップグレードするだけの価値は間違いなくあります。
βおよび CVS リリースの簡単な覚え書き: 開発者はプログラムに新しいバグを加えてしまったり安定を妨げないよう細心の注意を払いましたので、一般的に現在の CVS 版やβリリースは実際のリリース同様安定しています。CVS/βリリースと通常のリリースの唯一の違いは、次回のリリースのためにリストされている機能が完全に実装されていない事と、リリース前にバグや安定性を損なうものが全くないかきちんと確認するために、リリース候補は必ずテストしなければいけない事です。

2002年3月16日, gtk-gnutella での使用帯域幅が設定可能になりました

バージョン 0.80 安定版がかなり前からリリースされています、また Raphael は CVS バージョン (0.85 開発版) での開発を続けていて数多くの機能を加えたり修正したりしています。実際その価値はありますので、CVS から現在の gtk-gnutella をダウンロードして試してみて下さい。最も重要な拡張の一つは帯域幅の管理が組み込まれたことです。今回より gtk-gnutella は x バイト/秒以上の帯域幅を使わないよう設定できるようになります、モデムや遅い DSL 回線では大いに役立つでしょう。
帯域幅の管理を設定するにはファイル ~/.gtk-gnutella/config にある output_bandwidth と input_bandwidth の値を変更する必要があります。私自身は 10240 と 40960 に設定しています、これで私の 512/128kbps の回線にもいくらか帯域幅の空きを残しておけます。

2002年1月27日, 0.80-beta2 がリリース、ホームページに新しいスクリーンショットが載せられます

0.80beta2 は新機能の追加なしのバグ修正リリースです。ダウンロード、テストして残っているバグすべてを報告して下さい。
新しい gtk-gnutella の見た目がどのように素晴らしくなるのか興味がある方は、スクリーンショットのセクションで新しいスクリーンショットを御覧下さい。

2002年1月19日, 0.80-beta1 がリリースされました

詮索結果のフィルタリング、ハンドシェーキング・プロトコル (バージョン 0.6) および新しい ping/pong 方式の実装を通して使用される帯域幅の減少を含む、本当に多くの変更 (先週末のニュースを御覧下さい) がなされています。
残りの重要な変更が実装され次第バージョン 0.90 をリリースする予定です、つまり機能が一時凍結されます! ですので、よく調べ直して、CVS 開発版をテスト、見つけるすべてのバグを報告して下さるよう尾根がいます。

2002年1月12日, CVS で多くの大きな変更が行われました

基本的なコードのほとんどが変更されています。またより新しい Gnutella プロトコル (例えば 0.6 ハンドシェーキングのサポート) に合わせて最新の状態になっています、もっとも GUI は以前のものとほぼ同じように見えますが。隠れているバグを探すためにもぜひこれを試してみて下さい (CVS については開発に関するページを御覧下さい)。
まもなくバージョン 1.0 のリリースが予定されています、その後は完全に新しいコアと GUI での作業が始まります。この二つの部分を完全に別けることで、異なる GUI (KDE, ncurses 等) を gtk-gnutella の gnutella コアと使用できるようになります。

2001年12月4日, 少し前にバージョン 0.18 がリリースされました

が私はオフライン (基本的にまだそうです、なぜなら引越しをしたばかりで、ケーブルモデム・プロバイダが私のアカウントをまだ更新していないからです) でしたので更新できませんでした。いずれにせよ、常にSF のプロジェクトページで新着情報を確認するようにして下さい。もしメーリングリストに登録しているのでしたら、新しいリリースは何時になるのか聞いてみて下さい。そう何週間も後にはならないと思います...

2001年11月13日, 新しいウェブサイトを開設しました

今のところ (デザインは置いておいて) 大半は内部の変更、保守し易いようにしたり、ニュース記事等を加えています。これからもっと多くの内容、リンク、スクリーンショット等を追加していく予定です。何が欠けていて、どんなものにしたいか私 (maol - ウェブ管理者) に知らせて下さい!

2001年11月5日, まもなくバージョン 0.18 がリリースされます

プレビュー・バージョン (CVS で取得できます) にバグと思われるメモリリークが見つかっていますので、 まもなくバージョン 0.18 がリリースされます。

2001年10月24日, ついにバージョン 0.17 がリリースされました

このリリースでは、 CPU の使用率が体感できるくらい下がっています。特に多くのファイルを共有して (いるか)、多数のノードに接続している人達は分かるはずです。
3600 以上のファイルを共有して 7 基のノードと接続している 466 Mhz の PC では、一般的に CPU 使用率が 2% 以下になります。

2001年10月3日, バージョン 0.16 がリリースされました

コードが更に整えられ、様々な箇所で最適化されました。一部の明らかなバグも修正されています。

2001年9月10日

Raphaël Manfredi が驚異的な速度でパッチ、バグ修正および新機能を追加して gtk-gnutella の開発を引き継ぎました。gtk-gnutella が再び甦りますように。
