2021-04-20	Use arc4random whereever we need strong entropy	Dirk Engling

2021-04-20	Turn random() to nrand48 in inner loop where it is not cryptographically relevant to avoid futex storm. Thanks and credits to Bart Smienk	Dirk Engling

2017-04-28	Get rid of some warnings regarding header guards	Dirk Engling

2015-06-08	Increase number of locks to accomodate for more cores on contemporary CPUs	Dirk Engling

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.
2009-11-18	Preparing more efficient header parsing	erdgeist

2009-08-29	Enable limiting fullscrapes to only every 5 minutes per IP	erdgeist

2009-08-26	Introduce the concept of an ot_net into opentracker.	erdgeist

2009-06-15	Log networks in its old form has been disabled. Live logging may come back soon.	erdgeist

2009-03-17	Fix white spaces	erdgeist
	Introduce loading tracker states with -l Alter tracker state to a human readable form
2009-03-04	Add a stat option the count bucket stalls	erdgeist
	Add an iterator for all torrents. It's slower but for stats it's okay. Move some stats collection stuff to the new iterator. More to come. Start a "report all stats" page. Start fixing the code to identify "busy" networks. Add the concept of hosts allowed to proxy. Add a parser for the X-Forwarded-For: HTTP header. Clean up HTTP Header handling code. (Remove some left overs of now vanished sync code).
2009-03-03	Remove superfluous test for == NULL, when variable has been used, anyway	erdgeist

2009-01-16	Use a self pipe to wake from io_wait when a thread finished his work.	erdgeist

2009-01-15	We sent an incorrect reply dictionary vor v6 announces	erdgeist

2009-01-13	V6	erdgeist

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 root	erdgeist
	* 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.
2008-12-08	Make all torrents in their buckets sorted again.	erdgeist

2008-12-07	Handle program end more politely	erdgeist

2008-12-06	Renamed OT_FLAG to OT_PEERFLAG to make code easier to read	erdgeist
	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
2008-12-03	New peer flag to see, whether peer came from announce or sync	erdgeist

2008-12-01	Live Sync for peers that do not come back too early.	erdgeist

2008-11-28	The BIG refactoring [tm]. Too many changes to count them. If it doesn't suite you, revert to last version.	erdgeist

2008-10-28	Whitespace fixes	erdgeist

2008-10-06	Make ot_try_bind local again.	erdgeist

2008-10-04	added live sync code	erdgeist
	added a config file parser added tracker id changed WANT_CLOSED_TRACKER and WANT_BLACKLIST into WANT_ACCESS_WHITE and WANT_ACCESS_BLACK changed WANT_TRACKER_SYNC to WANT_SYNC_BATCH and added WANT_SYNC_LIVE added an option to switch off fullscrapes cleaned up many internal hardcoded values, like PROTO_FLAG,
2007-12-20	Introduce some kind of versioning	erdgeist

2007-12-03	Drop ot_{byte,word,dword} and use uint{8,16,32}_t, also simplify includes	erdgeist

2007-11-21	Fixing mmap allocation went to ot_mutex.c. Clean all torrents moved to ot_clean.c. Also make static buffers static	erdgeist

2007-11-12	Moving accesslist stuff to its own object	erdgeist

2007-11-12	Full scrape moves to its own object	erdgeist

2007-11-06	Move stats out of opentracker.c, also have an own file handle udp requests.	erdgeist

2007-11-06	No one can get access to buckets now without locking them. Also split up the trackerlogic.c-monster in functional sub-units. HEADS UP: this code is untested ↵	erdgeist
	and not considered stable.
2007-11-06	Make to_hex thread safe. Get rid off old /24 counting code. Protect more bucket accesses by locks.	erdgeist

2007-11-06	We do now use the tools for locking buckets in order to prepare MT code	erdgeist

2007-11-03	Introducing first tools to make opentracker multithreaded.	erdgeist

2007-11-02	Introduce configuration dependent number of parameters in a nicer way	erdgeist

2007-11-01	Allow for more than one admin ip address	erdgeist

2007-10-31	Add more full scrape stats	erdgeist

2007-10-29	Reenabled syncing	erdgeist

2007-10-27	Number of buckets is 1024 now	erdgeist
	Clean all torrents now only cleans one bucket at a time All torrents that are being worked upon in an announce are being cleaned on demoand torrent's peer lists now keep extra counts for seeds and peers to speed up scrape and announce Sync has gone for now. I will think up a new way to implement. The old one was way to slow.
2007-10-19	Introducing multiscrape	erdgeist

2007-10-19	After studying opentracker live data, I decided to radically reduce default allocation for vectors and making it grow faster instead: Most pools only had ↵	erdgeist
	one or two peers, wasting 815 or 814 bytes.
2007-10-19	Increase check interval for timeouted sockets to 10 seconds. That may prevent some disrupted scrapes.	erdgeist

2007-10-17	Increase send timeout. Also use an own variable for that.	erdgeist

2007-10-13	since gettimeofday is rather expansive, we do only fetch time once in a 5 second period, when we are delivered a SIGALRM.	erdgeist

2007-10-12	make 64bit safe	erdgeist

2007-09-26	New stats for s24s code, this is debug, do not use in real world	erdgeist

2007-09-10	An announce with event=stopped now returns correct number of leechers and seeders. In TCP and UDP.	erdgeist
