New in gtk-gnutella 1.1.15 (Jul 14, 2019)

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:
Rename statx struct to statistics to avoid name collision.
Browse_host_read_html(): fixed English typo.
Dl_util_query(): forgot to restore old signal handler.
File_info_restrict_range(): was not serving seeded files!

Added thread_stack_diff() to compare stack pointers.
Added PLURAL() macros.
Added clz64() to count leading zeroes on a 64-bit quantity.
Added OP_CTZ() and OP_CLZ() to work on op_t quantities.
Added pattern_memrchr() and pattern_strrchr() implementations.
Jumbo patch to use vstrrchr() instead of strrchr().
BIT_GENERIC_BIT() does not need the base argument.
Factorized prefix-matching from sorted array.
Pattern.c: fix compiling with old gcc (version 4.4)
Pattern.c: forgot to include "endian.h".
Str: avoid "char" as parameter or return type, use "int".
Windows: if not a "registered product", leave logs in current dir.
Windows: enhanced stack unwinding.
Windows: added option to debug backtraces "on crash" only.
Windows: when backtracing, also parse another MOV instruction.
Windows backtrace: also parse "add xx,%esp".
Compat_poll(): can now use poll() on Windows.

Rwlock_wait(): dump lock waiting queue when tracing sleeps.
Rwlock_wait(): trace summary when logging contention / sleeping.
Str_private(): declare non-leaking parts for TRACK_ZALLOC.

Thread-test: for interrupt tests, timeout if no interrupt received.
Thread_backtrace_capture(): avoid recursion and disable signals.
Thread_id_stack_used(): fixed for decreasing stacks.
Ut_frag_pmsg_free(): be more robust, avoid internal assertion.
Vmm_crashing_alloc(): better abort explicitly if no memory.

New in gtk-gnutella 1.1.8 (Dec 31, 2015)

New in gtk-gnutella 1.1.7 (Dec 15, 2015)

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.
Dump symbolic stack when crashing in supervised mode with our parent.
VMM: added new flag to signal OOM condition and be aggressive with the cache.
Options can now be abbreviated as long as they are not ambiguous.

[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 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.

Miscellaneous
Dutch translation updated.
French translation updated.

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".

Prevented random crash at shutdown time (improper cleanup ordering).
Prevent crash when running on linux kernels patched with grsecurity.
Fixed improper hop count display (always showing 2147483647) in horizon stats.

Fixed message statistics which were reading payload size from the header instead of relying on what was actually read.
OOB proxying code was not considering MUID collisions, causing memory leaks.
Was not always reconnecting to other Gnutella nodes when missing slots.

[GTK] New users were never able to see the preset filters in the menu.
Under the Hood:

Added CPU frequency scaling detection (Linux and Windows only) to be able to properly determine whether we are overloading the CPU.
Removed ShareMonkey URL support: they went out of business.
Use the DHT routing table as a source for new node addresses when the host caches are depleted, before attempting to contact the UHCs.
Throttle UDP pings so that we do not bombard a single host with many requests.
Limit Gnutella connection attempts to a given host to one per 2 minutes.
DHT routing table size now adjusts dynamically, lowering maintenance traffic.
Throttle received DHT lookups as a precaution against abuse from rogue nodes.
At startup time, sort cached host entries to put the most recent ones first.
Optimized QRP table merging loop.
Improved behaviour when facing stalling uploads.
Only send "DHT" in Gnutella pongs if the DHT runs in active mode.

New in gtk-gnutella 0.96.8 (Jul 20, 2011)

New in gtk-gnutella 0.96.7 (Jul 20, 2011)

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().

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.

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).

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.

New in gtk-gnutella 0.96.6 (Jul 20, 2011)

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.

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.
Updates:
Updated French, Japanese and Ukrainian translations.
Updated list of hostile IP ranges.
Updated list of bootstrap caches.
Updated list of country names and codes.
Improvements:
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.
