* Fix issue#2619
Prior to this change, websocket connection would not be disconnected
when dataframe type is other frametype. However, in mqtt spec, it
shoud be disconnected.
This change fix this inconsistent behaviour with mqtt 5.0
* 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
Fix websocket bug.
Prior to this change, websocket connection would be closed directly
without sending connack packet when acl check fails.
This change fix this bug.
* Pin cuttlefish rebar3 branch
* No shallow clone for rebar3
* Replace timer:sleep with receive after for deterministic
* Build with only rebar3
* bbmustache as a test dependency
* Change to plain deps
* Use shallow clone by default
* Add ct-helpers as test dep
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
Prior to this change, if a emqx_client:publish/? caller sends in
QoS=1/2 messages too fast, emqx_client may return
`{error, inflight_full}` which could put put the caller to an
awkward situation: there seem to be no ohter option except for
putting self to a sleep-n-retry infinite loop.
In this change, a new gen_statm state 'inflight_full' is introduced
as a sub-state of 'connected'. When emqx_client is in 'inflight_full'
state, it postpone all publish calls (for QoS=1/2) until inflight
window size shrinks.
