Future plugins will require emqx as a dependency.
This commit also brings back bcrypt to the system which was temporary
removed when converting to umbrella project
And move emqx app back to root level
After realising the challenges of developing plugins in standalone
rebar projects. it is perhaps more smooth to keep using emqx as
a rebar dependency
* refactor(channel): skip the ACL checking for inner subscribe
* fix(props): fix the prop_emqx_sys results of judgment
* Update esockd to 5.7.1
* test(topic-metrics): add test cases for topic metrics
* perf(emqx_vm): make emqx_vm:get_memory/0 more efficiency
- Add dialyzer for code analysis
- Correct all the module type declarations
- Use `-type()` to declaration a type instead of `-opaque`
(It is advantageous to the code dialyzer)
BROKEN CHANGES:
- Add a ?DEFAULT_SUBOPTS for emqx_broker:subscribe/1,2,3
- Remove the needless internal function `emqx_vm:port_info(PortTerm, Keys)`
1. Add MQTT5.0 properties when invoking the hooks.
- Add a new key `properties` into the message header:
We used to put all of the properties into the `#message.headers`:
```erlang
#message{headers = #{'User-Property' => {<<"reason">>,<<"normal">>},
'Message-Expiry-Interval' => 60,
allow_publish => true}
```
I put them instead under a single key:
```erlang
#message{headers = #{properties =>
#{'User-Property' => {<<"reason">>,<<"normal">>},
'Message-Expiry-Interval' => 60},
allow_publish => true}
```
Note that the column `properties` may contain all the properties for
Publish and Will messages.
- Add `disconn_props` into the `Channel.conninfo`
- Add `puback_props` also into the message header:
```erlang
#message{headers = #{puback_props =>
#{'User-Property' => {<<"reason">>,<<"normal">>}},
allow_publish => true}
```
2. Change the data type of `#message.headers` and `#message.flags` to map.
It used to support `undefined`.
