Build and Use on Linux

1. Checkout Skynet repo, and build it with make linux
2. Checkout FreeIOE repo, and create an soft link (ioe) in Skynet repo folder
3. Goto FreeIOE repo, run ./scripts/feeds update -a
4. Goto Skynet repo, run ./skynet ioe/config to start FreeIOE

Core Development

FreeIOE is based on Skynet framework.

More information can be found in its wiki FreeIOE works with on skynet with a few more lua C modules

freeioe's Issues

设备模型在应用删除后并没有正常删除

应用出现死循环的情况下，删除了应用。但是应用产生的设备模型还在系统中，并未被删除。

--
怀疑是fire_event导致的。 目前暂时关闭on_close失败的 fire_event。 留待观察。

Admin web page improvement

• Only refresh web page when application/system package download and install/upgrade completed!

• Web will be optional in FreeIOE

某些代码不全

看下图：

部分系统事件缺失

系统事件目前不完善，缺失以下事件：
1。 应用启动失败事件(ERROR)
2。 应用运行代码错误事件(WARNING)
3。 应用安装、更新、设定、删除事件 (INFO)
4。 TODO: HERE

The gateway fails to 'Queue is locked' state and will never recovered from this failure state

This happened when performing application installation or FreeIOE upgradation.

And the FreeIOE gateway will be not restart/reboot in this case.

The timestamp from skynet.now() may incorrect

skynet.now()返回的时间戳不准确，skynet内部时间戳增加的机制存在问题。 而os.time()的时间是准确的，目前的方案是对比这两个时间戳，当时间戳出现问题时（时间差值超过两秒)，让skynet退出从而更新时间戳绕过这个问题。

限制设备产生事件的数量

应用目前可以无限制产生事件，并上送至平台。 导致出现大量相同事件。

Show more device information in DeviceViewer

Currently the device viewer shows the connection information, which is not useful. We need shows FreeIOE Devices information instead of connection information.
e.g.

• SN
• FreeIOE version
• Skynet version
• Cloud connection status
• Current System Settings
• Device CPU/Uptime/Temp/GPRS and so on.

VS Code Extension Planned Features

1. Using Websocket instead of HTTP APIs

• Spport Auth Code instead of username/password
• Using WebSocket instead of current UDP/RestFul APIs

2. Application Package Export/Upload

• Export Application Package (zip format)
• Upload Application to App Center
