Hello Gnutella fans, I have just released version 1.2.0, which contains important fixes and really needs to be installed to replace 1.1.15.
Here's the ChangeLog entry for the release: # v 1.2.0 2020-06-14 [stable] 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. Improvements: - Let --compile-info show which malloc() is used. - It is now possible to run gtk-gnutella from a Docker container. - Added details in the README file about required packages to compile. - Use gradual bandwidth penalty when uploads are stalling. - Added upload bandwidth capping. - Forcefully reduce request chunk if b/w is limited. - Emit a Retry-After header on 416 replies. - On HTTP 416, emit a Last-Modified header. - Switched to IP2Location for mapping IPs to countries, dropping MaxMind GeoIP. - Upload tab now shows our own partial completion ratio, not just "(partial)". - Detect abuse from HTTP clients not reading payloads. - Enforce Retry-After softly. - Ban them when they abuse of the browse-host feature. - Smarter detection of duplicate incoming Gnutella connections. Bug Fixes: - [GTK2] Fixed file selector to avoid greyed-out folders. - [GTK2] Guarantee updating of properties when refresh button is clicked. - Added emergency path during startup should sbrk() fail. - Fixed instructions following build.sh run. - Fixed possible thread_self() instability at startup. - Fixed backward portability issue with the BFD library. - Fixed computation of build date. - Fix 2 harmful typos, affecting serving of partial files. - Regenrate Configure to fix gccversion usage bug. - Restored compilation of a standalone local shell. - Remove executable permissions on C source file! - Rename our ARC4 interface on systems with native arc4random(). - Updated all files to fix obsolete FSF postal address. - Avoid banning hosts issuing legitimate upload requests. - Implement GNU extension malloc_usable_size() when using our malloc(). - UHC: when hardwired list is exhausted, reload it. - Make Content-Range and Content-Length prioritary headers. - ban_allow(): was never returning BAN_FORCE. - download_reply(): reload available ranges after 416 if needed. - download_stop_switch(): forgot to remove passive queue indication. - gtk_gnutella_exit(): must close UPnP layer before HTTP. - http_send_status(): reworked to avoid undue header truncation. - node_g2_read(): fixed faulty assertion. - pb_token_found(): be more robust against unexpected input. - search_gui_close_search(): avoid crash when emptying search list twice. - update_available_ranges(): revisited range processing logic. - upload_416_extra(): was generating non-compliant headers. - vmm_dump_pmap_log(): fixed deadlock. - download_moved_with_bad_sha1(): always reset fileinfo. - file_info_reset(): also discard previous TTH info.
