11 days	Refactor ot_workqueue out of ot_mutex, no behaviour change	Dirk Engling

11 days	Make tcp worker multithreaded, too	Dirk Engling
	This shamelessly steals the model established in the UDP workers, i.e. if the kernel is able to bind multiple listening sockets to the same endpoint, we will share them across threads. If it can't, all threads will accept on the same socket. The fast path handles most of the connections, only the rare case of no data yet on the socket is offloaded to the slow path (which used to be the mainloop) for completion. This scales nicely, as the higher the load is, the higher chances are that an accept happens only after the network roundtrip to the peer completes, leading to more connections that already have data waiting for us. We also consolidate the workstruct init and deinit code, preparation for later unifying all thread state structs for all protocols (mca, udc and tcp). The config file gains a per tcp connection worker count and some docs explaining what this knob buys and costs, nudging the user to either keep it 0 or dial it up to at least 2.
12 days	Add test for new config params	Dirk Engling

12 days	Add config parsers for multiple tcp socket readers and a helper to see if we can offer it on the platform	Dirk Engling

12 days	Introduce a fast path assuming that a tcp connection's payload already has arrived at accept time	Dirk Engling

12 days	Fix idle tests in presence of an accept filter	Dirk Engling

12 days	Fix expiry tests under the new accept filters	Dirk Engling

12 days	Defer accepts until some data actually is there	Dirk Engling

13 days	Reduce syscalls and add helper to count them	Dirk Engling

13 days	Add an http load generator	Dirk Engling

13 days	Check for free port in the udp integration test, also speed it up by a bit	Dirk Engling

13 days	Consolidate all tcp/http tear down into a single http_close function to prevent a rare UAF for expiring connections	Dirk Engling

14 days	add wake-up tester that helped figuring out how to tickle hanging udp readers	Dirk Engling

14 days	Revert last wake-up experiment. Having each udp worker wake up once a second to check if the tracker stops is wasteful	Dirk Engling

14 days	Fix a test that would over-report success rate when losing the race for cycles to the test target	Dirk Engling

14 days	With more workers blockingly waiting on udp sockets, we need to keep track of all sockets to shut them down on exit	Dirk Engling

14 days	Let the load tester log losses to better gauge performance	Dirk Engling

2026-10-27	Add concurrency test	Dirk Engling

2026-10-27	All OSes now do have a cheap monotonic clock, so no caching thread is needed. Also add some relative time helpers	Dirk Engling

2026-10-27	Add test for the revived keep alive	Dirk Engling

2026-10-27	Fix some tests to match retired stats modes and wrong config file ordering	Dirk Engling

2026-10-27	Add test for the correct order of partial scrapes	Dirk Engling

2026-10-27	Add new test for connection keep alive	Dirk Engling

2026-10-27	retrieve the address of the sending socket for comparison. In jails it might be forced to its primary address	Dirk Engling

2026-10-27	Adding the actual tests to do aforementioned 'Massively increase coverage by pulling fullscrapes and sending udp packets'	Dirk Engling

2026-10-27	Massively increase coverage by pulling fullscrapes and sending udp packets	Dirk Engling

2026-10-27	add more checkers to the sanitizer and integration check runs	Dirk Engling

2026-10-26	Avoid an UB of adding NULL + 0 by keeping an offset instead of advancing the pointer into a vector struct	Dirk Engling

2026-10-26	Add integration test and its runner	Dirk Engling

2026-10-26	replace all calls to sprintf with a format helper that advances a cursor. Also convert the meta-formatter (i.e. results printer) to this scheme	Dirk Engling

2026-10-26	Replace libowfat's event waiter with our own abstraction	Dirk Engling
	It's with a heavy heart that I remove libowfat as my event library from opentracker. libowfat is what taught opentracker to walk and then fly. The tracker was literally standing on the shoulder of giants when I started writing it in 2006. For its time, the event abstraction was unparalleled and it has held up for many years, and it served the bittorrent community greatly. https://erdgeist.org/gitweb/opentracker/commit/?id=ad472597c569568bad0526d116b601dfcb36638c Unfortunately, it is very likely that libowfat will not be maintained anymore for the foreseeable future, it is already not easy to get its source from upstream and opentracker started receiving bug reports that I can not reasonably answer or patch. Before the project gets more dependent on the limitations of libowfat's current state, I need to teach opentracker to stand on its own feet and fly by itself. I've learned a great deal in the process and have even more respect now for what libowfat pioneered. The path for opentracker is cleared now. Ground work has already been laid in the migration process to support multi threaded http processing while keeping the aggressive reduction of syscalls alive that made the libowfat+opentracker combo so scalable. Here be some dragons, though: Even though there is a unit test suite now, the event loop's rewrite has not been battle tested yet. So you might want to hold up for a bit before jumping on the solo band wagon. What awaits at the end will be a long overdue v1.0, which will be named in honour of Felix.
2026-10-26	Add poll/epoll/kqueue wrapper to wait for events	Dirk Engling
