Dear Gnutella fans, A new release has just been uploaded to sourceforge. Here are the changes since 0.98.3, as listed in the ChangeLog file:
# v 0.98.4 2012-11-04 [stable] 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. Internationalization: - 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. Improvements: - [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.
