# TODO
|
|
|
|
* readme
|
|
* document privilege dropping and cpu pinning
|
|
* document access list log output levels and that it exits program
|
|
on start if parsing fails
|
|
|
|
* config
|
|
* add flag to print parsed config when starting
|
|
* fail on unrecognized keys
|
|
|
|
* implement socket_recv_size and ipv6_only in glommio implementations
|
|
|
|
* CI
|
|
* file transfer CI for all implementations
|
|
* test access lists?
|
|
* cargo-deny
|
|
|
|
* aquatic_udp
|
|
* notes
|
|
* load testing shows that with sharded state, mio reaches 1.4M responses per second
|
|
with 6 socket and 4 request workers. performance is great overall and faster than
|
|
without sharding. io_uring impl is a lot behind mio impl with new load tester
|
|
* what poll event capacity is actually needed?
|
|
* mio
|
|
* stagger connection cleaning intervals?
|
|
* uring
|
|
* ValidUntil periodic update
|
|
* statistics
|
|
|
|
* aquatic_http:
|
|
* clean out connections regularly
|
|
* Rc<RefCell<ValidUntil>> which get set on successful request parsing and
|
|
successful response sending. Clone kept in connection slab which gets cleaned
|
|
periodically (= cancel tasks). Means that task handle will need to be stored in slab.
|
|
Config vars kill_idle_connections: bool, max_idle_connection_time. Remove keepalive.
|
|
* handle panicked/cancelled tasks?
|
|
* optimize?
|
|
* get_peer_addr only once (takes 1.2% of runtime)
|
|
* queue response: allocating takes 2.8% of runtime
|
|
* use futures-rustls for load test
|
|
* consider better error type for request parsing, so that better error
|
|
messages can be sent back (e.g., "full scrapes are not supported")
|
|
|
|
* aquatic_ws
|
|
* glommio
|
|
* fix memory leak / huge growth
|
|
|
|
## Less important
|
|
|
|
* extract response peers: extract "one extra" to compensate for removal,
|
|
of sender if present in selection? maybe make criterion benchmark,
|
|
optimize
|
|
|
|
## aquatic_http_load_test
|
|
* how handle large number of peers for "popular" torrents in keepalive mode?
|
|
maybe it is ok
|
|
|
|
## aquatic_http
|
|
* test torrent transfer with real clients
|
|
* scrape: does it work (serialization etc), and with multiple hashes?
|
|
* 'left' optional in magnet requests? Probably not. Transmission sends huge
|
|
positive number.
|
|
* compact=0 should result in error response
|
|
|
|
## aquatic_ws_load_test
|
|
* very small amount of connections means very small number of peers per
|
|
torrents, so tracker handling of large number is not really assessed
|
|
|
|
## aquatic_udp
|
|
* use key from request as part of peer map key like in aquatic_http? need to
|
|
check protocol specification
|
|
|
|
# Not important
|
|
|
|
## General
|
|
* have main thread wait for any of the threads returning, quit
|
|
if that is the since since it means a panic occured
|
|
|
|
## aquatic_ws
|
|
* write new version of extract_response_peers which checks for equality with
|
|
peer sending request? It could return an arrayvec or smallvec by the way
|
|
(but then the size needs to be adjusted together with the corresponding
|
|
config var, or the config var needs to be removed)
|
|
|
|
## aquatic_udp
|
|
* Does it really make sense to include peer address in peer map key? I have
|
|
to think about why I included it in the first place.
|
|
|
|
## aquatic_udp_protocol
|
|
* Don't do endian conversion where unnecessary, such as for connection id and
|
|
transaction id?
|
|
|
|
## aquatic_cli_helpers
|
|
* Include config field comments in exported toml (likely quite a bit of work)
|
|
|
|
# Don't do
|
|
|
|
* general: PGO didn't seem to help way back
|
|
|
|
## aquatic_http
|
|
* request from path:
|
|
* deserialize 20 bytes: possibly rewrite (just check length of underlying
|
|
bytes == 20 and then copy them), also maybe remove String from map for
|
|
these cases too. doesn't really improve performance
|
|
* crazy http parsing: check for newline with memchr, take slice until
|
|
there. then iter over space newlines/just take relevant data. Not faster
|
|
than httparse and a lot worse
|
|
|
|
## aquatic_udp_protocol
|
|
* Use `bytes` crate: seems to worsen performance somewhat
|
|
* Zerocopy (https://docs.rs/zerocopy/0.3.0/zerocopy/index.html) for requests
|
|
and responses? Doesn't work on Vec etc
