Software update: Tixati 1.97

Tixati is a comprehensive, lightweight and efficient bittorrent client with support for dht, magnet links and rss feeds. The program provides extensive information about all aspects of the download and the incoming and outgoing network traffic. Downloads are available for Windows and Linux. In addition, a portable version can be downloaded. The program does not display advertisements, unlike for example µTorrent. Version 1.97 of Tixati has been released and its changelog looks like this:

DHT Overhaul

• significantly faster DHT search speed
• vastly better protection against DoS and Clone/Flood attacks
• new incoming transaction soft rate limiting system, to keep overall DHT traffic low under severe network conditions
• better cross-table high network concentration detection heuristics
• IPv4/6 cross-protocol bootstrapping improvements, better compatibility with Teredo systems

Transfers

• overhauled PEX (peer exchange) caching system
• increased maximum metadata size to accommodate extremely large torrents
• sparse file allocation is now the default method on filesystems that support it
• loosened file last-modified time matching rules (in an attempt to stop some reported problems with NAS units)
• eliminated a pause after clicking the Add button in some XP systems
• failing tracker will not fallback to unannounced mode while transfer is in running mode
• minor tracker protocol compatibility adjustments
• no downloading while checking during initialization phase
• fixed a crash in the preload window when Apply To All is checked and Skip Queue is selected

channels

• overhauled connection certificate caching system for more reliable connections
• using alternate threading strategy for channel stream piece decoding (eliminates a Win7-only handle leak caused by a faulty 3rd party POSIX threading library)
• stream titles show in chat via /streamtitles option
• option to randomize selected stream playlist items
• short duration ts/mp3 files are streamed more smoothly
• fixed several other minor bugs with stream title passthrough to media player
• version column in connections view
• channel-list search IP concentration limits loosened
• several minor protocol tweaks
• channel search function minor fixes

Elsewhere

• fixed problems with POSIX threading library on Win7 platforms (handle leak)
• fixed problems with system suspend/resume on Win7 platforms
• improved SSDP and SLRD local peer discovery port-bind error handling
• minor UPC protocol adjustments
• minor fixes in UPC socket diagnostic charts
• Linux system suspend inhibition is now more reliable
• fixed minor problems in XP systems with saving config files in too large of chunks
• better handling of URLs containing # symbol (in RSS and other places HTTP is used)
• updated IP Country database

Future/Soon/Next

• eliminate usage of file last-modified times to trigger checking (will instead keep block/file level hashes and use dynamic checking)
• overhaul of transfer multi-file management logic
• further investigation of some Win8 kernel panic problems (we did not observe problems on any of our Win8 systems, and are still trying to track this down)
• replacement of the .torrent auto-load system with something more reliable than the Windows file change notification API
• RSS auto-load / auto-start problems (this has also been difficult to recreate on our systems)
• a report of a Scheduler freezing problem
• overall framework upgrade to a leaner C++11 based system
