2018-04-25Add options to control h2's SETTINGS_HEADER_TABLE_SIZELoïc Hoguin
2018-04-23HTTP/2 informational responses don't end the streamLoïc Hoguin
2018-04-23Add missing enable_connect_protocol in typespecsLoïc Hoguin
2018-04-04Add initial implementation of Websocket over HTTP/2Loïc Hoguin
Using the current draft: https://tools.ietf.org/html/draft-ietf-httpbis-h2-websockets-01
2018-03-14Add case for handling infinity for idle/request_timeoutBartek Walkowicz
Currently cowboy assumes that idle_timeout or request_timeout is a number and always starts timers. Similar situation takes place in case of preface_timeout for http2. This commit adds case for handling infinity as a timeout, allowing to not start mentioned timers.
2018-03-13Handle system messages in cowboy_websocketLoïc Hoguin
2018-03-13Handle supervisor calls properly everywhereLoïc Hoguin
2018-02-28Fix crash in cowboy_http2 when content-length is invalidLoïc Hoguin
2017-12-13Fix Dialyzer warningsLoïc Hoguin
2017-12-12Don't badmatch on HTTP/2 preface's Transport:sendLoïc Hoguin
Send errors produce annoying logs and we notice the connection is gone later on anyway.
2017-12-06Also disable the TRACE method entirelyLoïc Hoguin
2017-12-06Disable the CONNECT method completelyLoïc Hoguin
It's safer than allow it with the wrong behavior.
2017-12-04Add an rfc7231 test suite, fix an HTTP/2 bug with HEADLoïc Hoguin
In some cases there could be a body sent as a response to a HEAD request when using HTTP/2. This has been corrected.
2017-11-30Fix HTTP/2 pushLoïc Hoguin
2017-11-29Don't send a GOAWAY frame on close when the h2 preface is invalidLoïc Hoguin
2017-11-29Ignore stray HTTP/2 stream messages that we expectLoïc Hoguin
2017-11-29Add many rfc7540 tests, improve detection of malformed requestsLoïc Hoguin
2017-11-27Add more flow control tests to rfc7540 and fix related issuesLoïc Hoguin
2017-11-27Add more rfc7540 tests along with their respective fixesLoïc Hoguin
2017-11-27Fix a few rfc7540 testsLoïc Hoguin
Cowboy takes a few shortcuts to avoid wasting resources when there is a protocol error. The RFC wants us to send a different error depending on the state of the stream at the time of the error, and for us to maintain the connection in cases where we would have to spend valuable resources to decode headers. In all these cases Cowboy will simply close the connection with an appropriate error.
2017-11-20Queue HTTP/2 trailers when there's still data in the bufferLoïc Hoguin
2017-11-15Add preliminary support for trailers in responsesLoïc Hoguin
This depends on changes in Cowlib that are only available on master.
2017-11-01Fix two edge cases for cowboy_req:stream_bodyLoïc Hoguin
Sending data of size 0 with the fin flag set resulted in nothing being sent to the client and still considering the response to be finished for HTTP/1.1. For both HTTP/1.1 and HTTP/2, the final chunk of body that is sent automatically by Cowboy at the end of a response that the user did not properly terminate was not passing through stream handlers. This resulted in issues like compression being incorrect. Some tests still fail under 20.1.3. They are due to recent zlib changes and should be fixed in a future patch release. Unfortunately it does not seem to be any 20.1 version that is safe to use for Cowboy, although some will work better than others.
2017-10-31Add some todosLoïc Hoguin
2017-10-29Add cowboy_req:inform/2,3Loïc Hoguin
User code can now send as many 1xx responses as necessary.
2017-10-25Introduce cowboy_req:sock/1 and cowboy_req:cert/1Loïc Hoguin
To obtain the local socket ip/port and the client TLS certificate, respectively.
2017-10-23Fix a bug in HTTP/2 where connection gets closed prematurelyLoïc Hoguin
When the user code was sending a response fully without reading the request body, the connection could get closed when receiving DATA frames for that body. We now ask the client to stop sending data via a NO_ERROR RST_STREAM, and linger any stream that has been reset so that we can skip any pending frames from that stream. This fixes a number of intermittent failures in req_SUITE, which now passes reliably. In addition a small number of rfc7540_SUITE test cases have been corrected as they were incorrect.
2017-10-21Fix stream handler state being discarded on terminateLoïc Hoguin
When we have to send a response before terminating a stream, we call info. The state returned by this info call was discarded when we called terminate after that. This commit fixes it. There are no tests for this, however the new metrics test in the next commit requires the correct behavior so this is ultimately covered.
2017-09-27Ensure the behavior on stream handler crash is consistentLoïc Hoguin
Also corrects the lack of error response when HTTP/1.1 is used.
2017-09-25Cleanup various commentsLoïc Hoguin
2017-09-25Avoid some crashes when HTTP/2 streams flush their responseLoïc Hoguin
2017-09-25Move body length count to cowboy_stream_h instead of protocolsLoïc Hoguin
The documentation was correct, the code was not. This should make it easier to implement new protocols. Note that for HTTP/2 we will need to add some form of counting later on to check for malformed requests, but we can do simpler and just reduce from the expected length and then check if that's 0 when IsFin=fin.
2017-09-21Centralize stream handler error reporting in cowboy_streamLoïc Hoguin
2017-08-21Tentative fix for out of order queued dataLoïc Hoguin
2017-08-08Implement the shutdown timeout for request processesLoïc Hoguin
This should work very similar to normal supervisors, in particular during the shutdown sequence when the connection process goes down or switches to Websocket. Processes that need to enforce the shutdown timeout will be required to trap exits, just like in a supervisor. In a vanilla Cowboy, this only matters at connection shutdown, as Cowboy will otherwise wait for the request process to be down before stopping the stream. Tests are currently missing.
2017-07-26Fix HTTP/2 server pushLoïc Hoguin
Cowboy was encoding the headers then decoding them when initializing the request. The problem is that the encoding and decoding contexts are not the same. Now, Cowboy will directly use the headers it received in the push command for the new request. This is also more efficient. I am surprised it worked at all considering the issue.
2017-05-31Don't terminate streams that were already terminatedLoïc Hoguin
This and the issues in the last two commits were reported by leo2007 on IRC.
2017-05-31Fix bad accounting of HTTP/2 windowsLoïc Hoguin
The previous code was incorrectly substracting the maximum frame size we could send when the data we were actually sending was much lower.
2017-05-31Apply the received SETTINGS frameLoïc Hoguin
2017-05-23Add many tests for RFC7540 5.1 and 5.1.1 and related fixesLoïc Hoguin
2017-05-19Preliminary h2 flow control supportLoïc Hoguin
Existing tests pass. A number of things remain to be done. Has only been tested with Gun so far. Feedback welcome!
2017-05-05Add inactivity_timeout and other options improvementsLoïc Hoguin
2017-04-18Get rid of stray messages when killing HTTP/2 request processesLoïc Hoguin
2017-04-18Make the default 204 response go through stream handlersLoïc Hoguin
2017-04-18Pass the HTTP/2 switch_protocol event to stream handlersLoïc Hoguin
To accomplish this the code for sending the 101 response was moved to the cowboy_http2 module.
2017-03-02Add more HTTP/2 tests for RFC7540 4.1 and 4.3Loïc Hoguin
2017-02-26Unknown HTTP/2 frames are ignoredLoïc Hoguin
2017-02-25Add many test cases covering RFC7540 4.2Loïc Hoguin
These tests cover frame sizes. It's mostly edge cases for sure (ie misbehaving clients and us having to reject them properly). I had these almost ready for a long time, so I'm glad I can push them out. This requires updating Cowlib too (we currently track master).
2017-02-05Remove or fix a small number of todo commentsLoïc Hoguin
One had the todo text fixed, another had the task to do done.
2017-02-05Fix sending of large files with HTTP/2Loïc Hoguin
Also finish implementing the relevant test, getting rid of todos.
