What I Touched

This week I have worked on Lua API of Sentry using its Objective-C and Android client. Add extern "C" around Lua C function in header compiled as Objective-C. LuaJavaBridge - Lua 与 Java 互操作的简单解决方案 是很详细的在 Cocos2d-x Lua 中调用 Java 方法的文章。不过有个地方已经过时了，就是 Java 的方法可以接收和返回 HashMap, 和 Vector (用 ArrayList 也可以）两种复杂变量的。有一些限制，调用的时候 Lua 不能传 nil，HashMap 对应的 Lua table 的 key 和 value 都会转成 String，在 Java 中可以强转成 HashMap<String, String>。Vector 对应的 Lua table 会当成是 list，所有成员也会转成 String，在 Java 中可以强转成 Vector<String>。对应的类型签名如下 Ljava/util/HashMap; Ljava/util/Vector; Ljava/util/ArrayList; Sentry-Android is an open source library to report errors in Android apps to Sentry. It is better than official Java library in my opinion.

This week I continue on cocos2d-x project automation build and dependencies management. By default, tolua registers global variables. A trick to use fallback Lua implementation by default is: # config.lua if _G.config then return _G.config end return { lua = true }…

This week I was setting up cocos2d-x project automation build and dependencies management using masterless saltstack. A minimum minion config, saved it as config/minion id: local file_client: local minion_id_caching: False root_dir: ./.salt file_roots: base: - .

This week I mainly worked on setting up monitoring system using prometheus and grafana.

This week I was setting up monitoring system using Prometheus. Some gotchas: Both prometheus and alertmanager accept command line flag -web.external-url to configure URL used to access the site and API. But if the external URL set in alertmanager contains path portion, alert manager will prepend the path to all web endpoints, which means prometheus should also add the path even access alertmanager through localhost:9093.

This week I worked on setting up gralog2 for logging search and analysis.

This week I setup servers using SaltStack and continue automate building and deployment using Gitlab CI.

This week I worked on syslog integration in skynet and delve into details of skynet. I also started using Gitlab CI.

This week I continue work on log system. I wrote a tool to sync Gitlab Issues with a Excel file.
