Gnutella 服务端/客户端实现，gtk-gnutella 0.98.4 发布

gtk-gnutella是Unix类系统下 Gnutella 的服务端/客户端实现，该软件依赖于 GTK+ (1.2版以上 ) 、 libxml，但Gnome不是必须的。目前，gtk-gnutella主要在Linux(Debian 3.1)下进行开发与测试，至少支持如下操作系统：Linux、 FreeBSD、 NetBSD、 Darwin、 Solaris、Tru64 UNIX (OSF/1)、 SGI IRIX、BeOS等，支持的CPU构架包括：x86、AMD64、PowerPC、SPARC、MIPS等。通过gtk-gnutella，可以分享、搜索、下载各种文件，gtk-gnutella的稳定性也很好。

这次发布的内容如下：

新的特性

• 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.

国际化

• Added French and Turkish translations of the FAQ.
• Updated French and Turkish translations.
• Fixed typo in a German translation.
• Cleanup of the English FAQ, updating obsolete answers.

改进

• [GTK] Show different icon and tooltip when port mapping done through NAT-PMP.
• [GTK] Flag results from servents with a banned GUID in the "Info" column.
• [GTK] Windows version now compiled with GTK 2.24.10.
• Non-sharing servents can now be promoted to ultra peers (in automatic mode).
• Be stricter about vendor messages origin: ignore them if from wrong protocol.
• Strip GGEP "NP" key from relayed queries.
• Use higher-priority UDP messages for important or time-sensitive data.
• Use semi-reliable UDP to transfer critical data (query hits).
• Make sure the queries we OOB-proxy have a GGEP "SO" key for secure OOB hits.
• Ignore unsecure OOB hit promises from hosts known to support secure OOB.
• Use some of our connected ultra nodes when filling UHC pongs.
• Updated GeoIP databases.
• When resuming from crashes, do not stop session-only searches.
• Persist selected search media types from session to session.
• Report last modification time + available size of partial files in hits.
• Added "webm" and "zoo" to the list of file extensions that can be shared.
• Display unexpected command-line argument before usage output.
• The shell "status" command now shows how port mapping was done, if any.
• Do not forward "What's New?" queries to leaf nodes with empty routing tables.

Bug Fixes

• Avoid segmentation fault if GUESS 0.2 cache is empty.
• Avoid SDBM crash when clearing database which had big keys/values present.
• Use signed arithmetic to compute compression ratios.
• Consider x.x.x.0 as a possibly valid IPv4 address.
• Was not correctly parsing the saved PARQ queue, causing undue forgetting.
• Fixed key accounting in DBMW.
• SDBM was sometimes not iterating over unflushed dirty LRU pages.
• Fixed wrong DHT value response message format.
• Fixed crash when attempting to browse host on a queued source.
• Do not route duplicate queries with higher TTL to leaves.
• Prevent sending of duplicate (locally issued) OOB-proxied queries.
• Fixed startup crash bug on Ubuntu machines.
• Changed the Debian menu icon to use the one which is 32x32, as lintian wants.
• Fixed auto-restart function on 64-bit Windows.

Under the Hood

• [GTK] Darken the color used to display partial results (yellow -> dark gold).
• Various PARQ cleanup to smooth QUEUE callback operations.
• Fallback to pre-computed symbol file when loaded symbols are garbage.
• Relax file_path_set() and open_read() to gracefully handle relative paths.
• get_folder_basepath(): protect against unsuitable environment variables.
• Recompute the amount of banned fds dynamically as config parameters change.
• Detect series of unclaimed OOB hits from a host to ignore further queries.
• Changed MUID marking strategy in queries to better accomodate OOB proxying.
• Added a UDP TX scheduler to optimize datagram sending by priority.
• Enhanced the incremental zlib operations, reusing objects across operations.
• Added new official ISO 3166 country codes.
• node_read(): was wrongly resizing the message buffer for each message!
• Refactored aging table to lower memory footprint (by 6 pointers per entry).
• On Windows, keep last 3 stdout/stderr logs, created when launched from GUI.
• Send important UDP messages with a "control" priority.
• Count TCP push-proxy requests aimed at firewalled-to-firewalled connections.
• Patch UDP PUSH messages aimed at initiating firewall-to-firewall transfers.
• Count received PUSHes requesting FW-FW transfers, plus those targeting us.
• dht_init(): do not reset the KUID if DHT disabled at startup.
• Detect whether we are restarting after a clean shutdown or after a crash.
• bg_task_terminate(): don't panic at shutdown when handling unaccounted tasks.
• Reserve only about 40% of the available virtual memory space on Windows.
• Always discover port-mapping devices, even if they won't be used.
• Ensure reasonable TTL and hops for PUSH messages from UDP we will route.
• The shell "nodes" command now displays the gnet port along with the address.
• Added metaconfig check for malloc() superseding.
• New switch --disable-malloc added to build.sh to prevent superseding malloc().
• When launching gdb during crash, ask for threads and thread stacks as well.
• External IP changes were not waiting for 3 hosts in 3 different CIDR ranges.
• Removed too restrive permissions in the man page (COPYRIGHT section).
• Shell meta-chars in executable path do not prevent loading symbols via BFD.
• Added more DHT statistics.
