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.
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).
* 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.
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,
1. stats for added and removed torrents
2. stats for start and stopped events from peers
this should help to detect DoS attacks and is useful for
profiling
