* Adopt channel architecture and improve the MQTT frame parser
* Update the test cases for emqx_channel, emqx_protocol
- Improve emqx_client to Use the new emqx_frame:parse/2
- Update the ct suites for emqx_channel, emqx_ws_channel
* Fix test case
To fix issue#2303(https://github.com/emqx/emqx/issues/2303)
It will report the following error, when a connection sends a TCP frame contained many of MQTT packet and followed a split MQTT packet.
* Improve emqx_hooks and credentials
1. Modify the return modes of emqx hooks.
Change the return value of hook functions to:
- ok: stop the hook chain and return ok
- {error, Reason}: stop the hook chain and return error
- continue: continue the hook chain
And the return value of emqx_hooks:run/2 is changed to:
- ok
- {error, Reason}
And the return value of emqx_hooks:run/3:
- {ok, Acc}
- {error, Reason, Acc}
2. Treat password as a member of credentials.
Password should be wrapped in the `credentials` data-structure, as the
username/password pair together consists of an authentication method.
There can be some methods using some other credential data (e.g.
a JWT token), and these credential data should also be wrapped in the
the `credentials` data-structure.
An event `client.authenticate` is triggered when an user logs in:
```erlang
emqx_hooks:run('client.authenticate', [], Credentials)
```
A `default callback` that deny/allow any user (according to the
`allow_anonymous` config) should be appended to the end of the
callback chain.
The `credentails` is passed through all of the callbacks, and
can be changed over in this process.
* Refactor emqx hooks return mode
* Remove password from PState
* Delete response_topic_prefix
The Response-Infomation in CONNACK was misinterpreated, it should
not be a broker's global config, instead, it should be per-client
or even per-session prefix/suffix mechanism
* Delete request-response code from emqx_client
* Add request-response test code
* meck as default dependency --- temp workaround for dep-vsn-check
* Fix the Exit in testcases
* Fix Exit in emqx_mod_sup_SUITE
* Update testcases for log_tracer
* Fix Exit in emqx_protocol_SUITE
* Add will_acl_check
* Fix more Exits
* Fix failed test case
Prior to this change, terry-xiaoyu enhanced the cuttlefish to
support emqx enterprise edtion configuration entries. But it cause 6
test case failed.
* Fix dep-vsn-check
* Fix issue#1874
Prior to this change, if user use one client connect emqx with mqtt
v3.1.1, the client subscribe the topic and publish message to this
topic, it would receive this message itself published, this commit
provide a configure option to let user ignore the message itself published.
This change fix issue 1874.
* Small Fix
* Fix bug
* Better design
* Fix compile warning and improve coverage
* Better design to solve the performance issue
* Fix typo
* Fix typo
* Delete spaces in end of lines.
* Do not use anonymous function
* Better performance
Add request & response support for CONNECT & CONNACK
Prior to this change, there is no validate and specified process for
Request-Response-Information and Response-Information
Also added basic Request/Response functionality to emqx_client implementation
