2015-06-05Avoid reacting to our own error packets, should the happen to end up on our interface with a spoofed source IP. Thanks to zorun.Dirk Engling

2012-05-28udp now generates a cryptographically secure token for connecting clients. This is later verified.erdgeist

2010-04-22** struct ot_workstruct gets ritcher (and will become even ritcher soon).erdgeist
This is where we encapsulate all per-request data from peer to hash to peer_id, so that it is available everywhere without passing hundreds of pointers down the stack. Most functions that do work down the stack now accept an ot_workstruct and some flags. So it can end up in the stats/event-handler where it will be the default parameter in the future. ** peer_id is now being copied by default and moved to ot_workstruct So it is available in stats and subsequent functions. ** sync scrape madness is gone SYNC_SCRAPE was intended to sync tracker state that would normally be lost on restarts i.e. downloaded counts per torrent. The way was to push it in the tracker cloud after finding all neighbouring trackers. This is madness. It never was tested and can be done per tracker by fetching stats/mode=statedump from time to time and starting opentracker with the -l option later. ** livesync thread has its own ot_workstruct now So it can behave like ot_udp and ot_http against trackerlogic.c and get rid of the first half of the embarrassing global variables. The sending half will be fixed soon [tm]. ** stats can log completed events The author recognizes the needs of original content distributors to keep track of the amount of times a work has been downloaded. While not feasible and used on openbittorrent and other open and anonymous tracker installations, a tracker user can now choose to send those events to syslog.
2009-06-15Dont log connection id missmatches anymoreerdgeist
2009-01-15Add comments, rename our struct http_data h to cookie, all clientsockets to sock, all size_t from socket_recvs to byte_count. Make signal handler set ↵erdgeist
default handler for the second SIGINT
2009-01-05* http and udp routines now use thread local buffers passed in workstruct containers. In other words they do not use static_buffer anymore and are ↵erdgeist
considered to be thread safe. * the new workstruct also introduces a well defined buffer and result passing path * a new function scan_find_keywords is a wrapper around scan_urlencoded_query that maps keys in url to values passed in an array of ot_keywords structs * this new function cleans up much of url parameter parsing work, where read_ptr and write_ptr have been introduced rather than the confusing char *c, *data variables * I now use memcmp instead of byte_diff to allow compiler to optimize constant size string compares * got rid of UTORRENT_1600_WORKAROUND * livesync_ticker is now only called from one (currently main) thread to avoid race conditions
2009-01-02* opentracker now drops permissions in correct order and really chroots() if ran as rooterdgeist
* lock passing between add_peer_to_torrent and return_peers_for_torrent is now avoided by providing a more general add_peer_to_torrent_and_return_peers function that can be used with NULL parameters to not return any peers (in sync case) * in order to keep a fast overview how many torrents opentracker maintains, every mutex_bucket_unlock operation expects an additional integer parameter that tells ot_mutex.c how many torrents have been added or removed. A function mutex_get_torrent_count has been introduced.
2008-12-06Renamed OT_FLAG to OT_PEERFLAG to make code easier to readerdgeist
Introduced READ16/32 and WRITE16/32 makros to abstract loading/storing from unaligned addresses away on cpu's that can actually load/store everywhere Removed all unnecessary memmoves, especially where it only moved 6 bytes in inner loop. I replaced them with WRITE16/32(READ16/32()) makros
2008-11-28The BIG refactoring [tm]. Too many changes to count them. If it doesn't suite you, revert to last version.erdgeist
