2019-05-09No longer accept mix of Ranch/socket options as listLoïc Hoguin
2019-05-08Add the num_conns_sups optionjuhlig
This new option allows configuring the number of connection supervisors. The old behavior can be obtained by setting this value to 1. A value larger than num_acceptors will result in some connection supervisors not being used as the acceptors currently only use one connection supervisor.
2019-05-08Retrieve the conns_sup in the acceptor start functionjuhlig
With the resolution of the pid of a conns_sup in acceptors_sup and thus in the child spec, a crash of a conns_sup and subsequent crash of the associated acceptor causes restarts of the acceptor to fail.
2019-05-06Fix some whitespaceLoïc Hoguin
2019-05-06Create one ranch_conns_sup per num_acceptorjuhlig
This gets rid of a bottleneck that occurs when many connections are handled by a single supervisor. The bigger issue occurred when many connections were dropped at once and the supervisor couldn't keep up.
2019-04-29Remove socket optionj.uhlig
2019-04-29Fix repeated removal of connectionsjuhlig
Due to a typo, repeated calls to ranch:remove_connection/1 from a worker process would crash the respective ranch_conns_sup.
2019-03-18Fix Dialyzer warning on unknown `ssl_cipher:erl_cipher_suite/0' typeGuilherme Andrade
* Up until OTP 21.0 it was defined on the ssl_cipher[0] module * On OTP 21.1 it was moved into ssl_cipher_format[1] * On OTP 21.3 it was moved into ssl[2] [0]: https://github.com/erlang/otp/blob/OTP-21.0/lib/ssl/src/ssl_cipher.erl#L56-L60 [1]: https://github.com/erlang/otp/blob/OTP-21.1/lib/ssl/src/ssl_cipher_format.erl#L40-L44 [2]: https://github.com/erlang/otp/blob/OTP-21.3/lib/ssl/src/ssl.erl#L136-L140
2018-11-26Use the correct CRC32 algorithm for the PROXY headerLoïc Hoguin
Turns out it wasn't the plain CRC32 algorithm that should have been used, whoops! The implementation was adapted from pseudo code from Thomas Cioppettini. I've renamed the PROXY header building option value for checksum from crc32 to crc32c and updated the documentation. There is no support for plain crc32 checksums.
2018-11-14Document the PROXY-related functions; prepare 1.7.0Loïc Hoguin
2018-10-23Add ranch:recv_proxy_header/2Loïc Hoguin
This is the function that should be called regardless of TCP or TLS being used. The proper usage for this function is: {ok, ProxyInfo} = ranch:recv_proxy_header(Ref, Timeout), {ok, Socket} = ranch:handshake(Ref), ... Ranch takes care of everything else under the hood. Transports now need to have a Transport:recv_proxy_header/2 function. For ranch_ssl the function gets the port from the sslsocket() record and then calls ranch_tcp:recv_proxy_header/2 with it. This means that two undocumented features are currently used for this, but the interface is really nice so that's a sacrifice worth doing. Also worth noting is that OTP 22 should have an alternative for gen_tcp:unrecv/2 so the only real issue is about the sslsocket() record at the moment.
2018-10-10Fix a race condition on restart after listener_sup crashLoïc Hoguin
The race condition occurs when the restart is faster than the cleaning up. With this commit the restart will perform the cleanup if it was not done beforehand.
2018-10-10Make the acceptors exit rather than crash on socket closeLoïc Hoguin
This will avoid some unnecessary logs by default. SASL can be enabled to log these events.
2018-10-10Add ranch_tcp:recv_proxy_header/2Loïc Hoguin
This uses the undocumented function gen_tcp:unrecv/2. Tests have been added for both gen_tcp and ssl connections, including sending data in the same first packet, at least for gen_tcp (ssl tests may or may not end up buffering some of the TLS handshake before the recv call, but there's no guarantees).
2018-10-09Add functions to build the PROXY protocol headerLoïc Hoguin
Also add tests of the type parse(build(Info)), including for testing the TLVs and the padding/checksum verification options.
2018-10-08Add initial ranch_proxy_header implementationLoïc Hoguin
Using test cases from the spec and tomciopp/proxy_protocol. Many more tests are needed, especially for the TLV part and for the error conditions.
2018-10-04Fix inconsistent naming of filter_user_options/2 argumentKim Shrier
2018-09-17Clean listener options after normal shutdownjuhlig
In addition to cleaning when ranch:stop_listener/1 is called, we also need to clean when we detect the supervisor is going away for normal reasons, because the supervisor might be in another application's supervision tree. Note that there might be a short delay in this case before the cleanup is done, due to using monitors for detection.
2018-08-13Export the function ranch:normalize_opts/1Loïc Hoguin
This can be used by Cowboy to better deal with the switch to maps for transport options and avoid the log message when using lists.
2018-08-01Remove R16 compatibilityLoïc Hoguin
Ranch is now made for and tested on 18+ only.
2018-08-01get_status now reports running when acceptors_sup is restartingj.uhlig
2018-08-01Fix ranch:wait_for_connections_loop/4 intervalLJZN
2018-07-31Correct the sendfile specs for the filenameLoïc Hoguin
2018-07-31Fix some whitespaceLoïc Hoguin
2018-07-18Add one manual per function for the ranch moduleLoïc Hoguin
Also review and update the ranch(7) manual and fix a few specs.
2018-07-05Hide cacerts from the listen error logLoïc Hoguin
It can be quite huge and hinders readability.
2018-07-05Add a logger transport optionLoïc Hoguin
I had to use the process dictionary to work around the current interface for one log call. You have been warned.
2018-07-04Return errors from Transport:handshakeLoïc Hoguin
The "normal" errors are still silenced when calling ranch:handshake.
2018-07-04Enable TLS upgrades via ranch_ssl:handshake/3Loïc Hoguin
Based on the work done by @juhlig.
2018-07-04Better distinguish between Ranch and socket optionsLoïc Hoguin
A map should now be used when specifying transport options that contain more than just socket options. It is still possible to pass a list of socket options directly as a convenience. The ack_timeout is renamed to handshake_timeout when specified as a map. This corresponds to the new function ranch:handshake/1,2 that will be favored in Ranch 2.0. Specifying Ranch-specific options via the proplist will no longer be possible starting from Ranch 2.0.
2018-07-02Mark ranch:accept_ack/1 as deprecatedLoïc Hoguin
2018-07-02Remove an old R16B01/02 workaroundLoïc Hoguin
Next release will only support 18+.
2018-07-02Introduce Transport:handshake/1,2j.uhlig
This commit deprecates Transport:accept_ack/1 in favor of a new forward-compatible function. Transport:handshake/1,2 will use ssl:handshake/2,3 from Ranch 2.0 onward.
2018-05-17Add a function to wait for number of connectionsj.uhlig
LH: Reworked validation style and added a -dialyzer attribute to acceptor_SUITE to silence expected errors.
2018-05-16Ensure listener restart with changed TransOptsj.uhlig
2018-05-16Add configurable restart intensity for ranch_supj.uhlig
2018-05-02Add suspend/resume of listeners and update of transport optionsj.uhlig
This allows graceful draining of connections, updating transport options on a running listener without having to drop connections and other similar scenarios. Note that when updating transport options the listener must be suspended which means that new connections will be rejected until the listener is resumed.
2018-04-10Ranch 1.5.01.5.0Loïc Hoguin
2018-04-10Prevent ranch_conns_sup from stopping on unexpected messagesLoïc Hoguin
2018-03-14Fix ranch:info/0 and ranch:procs/2 in embedded modej.uhlig
2018-01-22Added transport functions getopts/2, getstat/1 and getstat/2Jan Uhlig
2017-06-07Update Copyright to 20171.4.0Loïc Hoguin
2017-05-31Deprecated ranch:start_listener/6 and child_spec/6Loïc Hoguin
The NumAcceptors argument has been moved to transport option num_acceptor, which defaults to 10. The functions now take one less argument. The old functions are still here, though deprecated.
2017-01-31Format eacces errors in a more readable wayMichael Klishin
Amended with small whitespace changes and removing an unused clause.
2016-11-24Add ranch:info/0 and ranch:procs/2Loïc Hoguin
Provides detailed information about Ranch listeners
2016-11-24Don't attempt to start ssl anymoreLoïc Hoguin
Ranch now depends on SSL. Users embedding listeners in their supervision tree are expected to depend on SSL too if they are using it.
2016-11-24Update copyright yearLoïc Hoguin
2016-11-15Fix acceptors getting stuck because of socket errorsLoïc Hoguin
We always get the acceptor to resume. The child process will be killed, and the current code will ignore any EXIT message when that happens because the pid isn't in the process dictionary.
2016-11-15Track removed connectionsJames Fish
2016-11-15Improve error reportingAlexey Lebedeff
Simplify some return values, improve error messages for eaddrinuse and no_cert. Amended to add tests and simpler code. Also hides the contents of cert and key transport options, if any.
