Dear Gnutella fans, I have just released gtk-gnutella 1.1.3, with the following changes:
# v 1.1.3 2015-04-08 [stable] This is mainly a critical bug-fixing release, addressing a huge shortcoming in 1.1.2: all Shareaza leaves are incorrectly flagged as being fakes and are being removed quicktly from ultrapeers, creating network churn and instability. ===> Everyone running gtk-gnutella as Ultrapeer must upgrade to 1.1.3 quickly. Releasing shortly after 1.1.3 was also a pretext for improving stability on Windows platforms, especially after restarts: because Windows does not support the "close on exec" flag on file descriptors, restarted processes were left with several instances of a listening socket bound to the same port, causing havoc as behaviour is totally undefined and was most probably leading to the inability for the process to get any incoming connections. On Windows, we now also monitor the memory usage more closely, in order to avoid the C runtime from issuing a (blocking) popup signalling a fatal memory allocation error should it run out of space. More generally, the VMM layer is now capable of trapping fatal memory allocation errors and handling them more efficiently. In particular, when everything has failed, the layer can request a brutal restart of the process. Under less dire circumstances, a graceful restart will be requested. This was also an occasion to revisit the long-term allocation strategy in the VMM layer and optimize it in order to further limit fragmentation of the VM space. Even though avoiding fragmentation matters mostly for 32-bit applications, this also limits the amount of individual memory region mappings the kernel has to maintain and gtk-gnutella has to keep track of. Finally, a last-minute bug fix where a user reported a deadlock in the QRP processing code. After investigation, it turned out that there was indeed a recursive locking on a spinlock that had escaped all real-life testing out there so far! Improvements: - [GTK2] Added popup menu icon in front of "force push mode" for sources. - [GTK2] Added warning icon in status bar when kernel runs short of net buffers. - Increased default node connection timeout and size of the quick connect pool. - Updated the shell "status" command to display "!IP" on net buffer shortage. - Updated FAQ along with French and Turkish translations. - Updated GeoIP databases. Bug Fixes: - Fixed invalid test for "fake" Shareaza that led to network instabilities. - Made QRP lock a mutex to allow for recursive locking through qrp_comp_done(). Under the Hood: - On out-of-memory conditions, attempt to auto-restart if possible. - Windows: monitor committed memory, crashing before the kernel would kill us. - Added crash_restart() and controlling routines to request smooth restart. - On network buffer shortage (ENOBUFS), stop TCP connections for a while. - UPnP: protect upnp_mapping objects given to callbacks with reference counts. - Adjusted lock tracking when locks are disabled, fixing lock swapping. - Windows: remember socket descriptors so that we can close them on exec(). - Refactored code for listening sockets to warn when bound port is already used. - When shutdowning in "crash mode", skip most of the memory cleanup. - rwlock_destroy(): make sure to write-unlock the lock if it was owned. - waiter_ack(): don't panic if waiter was not notified, but loudly complain. - upnp_map_natpmp_publish_reply(): trace given port on NAT-PMP mapping errors. - upnp_discover(): force selection of IPv4 interface for UPnP discovery. - thread_unsuspend_others(): relaxed hard assertion into a soft one. - alloc_pages(): try harder on OOM conditions to allocate from the page cache. - socket_connect_finalize(): fixed wrong errno processing for connect(). - socket_connect_prepare(): no need for SO_REUSEADDR for connecting sockets.
