Prior to this change, if user's computer has no `~/.config/rebar3`
path, `make run` would fail and report enoent error.
This change fix the problem I described above.
* 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
* 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
Prior to this change, this project support to be built with rebar3 and
erlang.mk meanwhile but when we want to make distclean, this project
would execute rebar-clean which would get dependencies via rebar3, it
slow down the procedure of distclean.
