`cocos2dx非完整` 日志模块增量更新

在上一篇文章中,说到了"流程"的由来,以及我对流程的使用. 这一片就是对流程的应用.前一篇文章中说到了三条流程 check_log_measure, check_env_measure, check_update_measure.先来看看chenck_log_measure的源码:

这边是启动sys_logger, 我在启动结束的时候添加到全局表,这样方便操作.启动sys_logger以后,方便记录app在运行时候的情况.出现了问题也方便定位.当然,不同开发者对于问题的处理方式是不一样的,我是习惯这样做.然后给出check_env_measure的源码:

check_env主要是对平台的一些处理,我模仿操作系统去初始化一些环境变量,并以oop的方式添加到env_profile里面，env_profile主要是简单数据结构,提供的只是getter/setter方法。这里有一点需要注意的是,我根据配置文件修改了searchpaths,这主要是应对我们的更新模块,如果更新了新的文件,放在writable_path下面的一个指定目录,那么应该先从这个目录搜索,然后再去搜索apk中的资源目录.其他的环境变量有一些是配置文件配置的,有一些则是网络启用相关的判断,当然,在启动的过程中，依次初始化判定网络状态是不可靠的,因为网络状态可能随时关闭,不过我有仔细想过这个问题:在这么极短的时间内,我们可以认为这个环境变量是可靠的,所以不需要要担心这个问题了.

下面是配置文件env_conf:

 1 search_paths = {
 2     fw.platform.get_writable_path() .. "res",
 3     fw.platform.get_writable_path() .. "src",
 4     "res",
 5     "src",    
 6 },
 7 
 8 check_update = true,
 9 update_always= true,
10 
11 http_server_url = "http://192.168.1.131:8000/web/serverInfo",

配置文件我是使用classickv模式读取的,也就是支持lua syntax的,所以我们可以直接使用之前初始化的lua模块.这样很方便.我现在主要是配置了searchpath和更新模块的相应参数.下面看一下更新流程的源码:

可以看到这个流程其实主要都是处理ircu模块抛出的事件,然后就执行流程跳转的相关操作.根据之前的env_conf配置文件中的相关参数,我们可以给项目添加debug开关，如果在开发过程中可以屏蔽掉更新模块,当然我是没有添加

这个也很容易做到.在合适的配置添加:

1 if not envprofile:get("check_update") then
2      sys_logger.info("%s", "更新模块没有开启!“)
3      self:finish()
4      return
5 end

这个还是很简单的.下面就看看ircu模块,也就是我们的增量更新模块：

这个模块使用很简单,需要注意的就是下面这几个抛出的事件就行了,我将这个模块独立封装出来,就是依靠事件来保持低耦合的.

1 ircu.CANNOT_CONN_TO_HOST = "CANNOT_CONNECTION_TO_HOST"
2 ircu.START_IRCU_UPDATE   = "START_IRCU_UPDATE"
3 ircu.ALREADY_NEWEST      = "ALREADY_NEWEST"
4 ircu.IRCU_UPDATE_FINISH_SUCC = "IRCU_UPDATE_FINISH_SUCC"
5 ircu.IRCU_UPDATE_FINISH_PART = "IRCU_UPDATE_FINISH_PART"
6 ircu.IRCU_UNCOMPRESS_FILE    = "IRCU_UNCOMPRESS_FILE"
7 ircu.IRCU_UPDATE_START_PART  = "IRCU_UPDATE_START_PART"

当然,这几个事件除了错误代码之外,其他都是用来做更新界面百分比显示,以及显示更新信息的.ircu模块中使用了我写的c++的异步下载和解压函数.也就是fw.ircu_helper.download/uncompress.下面我给出我的这个C++模块:

好吧,就到这里了.下面来说一下log. 之前我也写过log模块,但是没有文件记录模块,我这边想要的功能就是同时在终端显示,然后又可以写入到文件.好了,从这个需求出发,我到Github去浏览了一下lua的代码,最后发现了zengrong的仓库, 这里给出他的地址: github.com/zengrong.所以我就从他的log模块取出了部分修改了一下:

 1 --小岩<757011285@qq.com>
 2 --2015-5-28 1:37
 3 local l = class("logger")
 4 
 5 l.CRITICAL = 50
 6 l.ERROR    = 40
 7 l.WARNING  = 30
 8 l.INFO     = 20
 9 l.DEBUG    = 10
10 l.NOSET    =  0
11 
12 function l:ctor(level, ...)
13     self:set_limit_level(level or l.NOSET)
14     self.chanels_ = {...}
15 end
16 
17 function l:set_limit_level(ll)
18     self.ll_ = ll
19 end
20 
21 function l:get_limit_level()
22     return self.ll_
23 end
24 
25 function l:add_log_chanel(lc)
26     self.chanels_[#self.chanels_ + 1] = lc
27 end
28 
29 function l:clear_chanel()
30     self.chanels_ = {}
31 end
32 
33 function l:flush()
34     for __, lc in pairs(self.chanels_) do
35         lc:flush()
36     end
37 end
38 
39 function l:log(level, fmt, ...)
40     if level < self.ll_ then 
41         return
42     end
43     args = {...}
44     for __, lc in pairs(self.chanels_) do
45         lc:emit(level, fmt, args)
46     end 
47 end
48 
49 function l:critical(fmt, ...)
50     self:log(l.CRITICAL, fmt, ...)
51 end
52 
53 function l:error(fmt, ...)
54     self:log(l.ERROR, fmt, ...)
55 end
56 
57 function l:warning(fmt, ...)
58     self:log(l.WARNING, fmt, ...)
59 end
60 
61 function l:info(fmt, ...)
62     self:log(l.INFO, fmt, ...)
63 end
64 
65 function l:debug(fmt, ...)
66     self:log(l.DEBUG, fmt, ...)
67 end
68 
69 return l

我这边只是给出了logger的接口,如果需要的话,请直接去看zr的github.请原谅我并没有在源码中给出引用出处.下面就是app配置Logger的文件:

 1 luagarbage_setpause_val     = 100,
 2 luagarbage_setstepmul_val    = 5000,
 3 
 4 app_name = "firework 小岩<757011285@qq.com>",
 5 
 6 gl_win_size       = cc.rect(0,0,960, 640),
 7 gl_frame_size     = cc.size(1140, 650),
 8 
 9 dr_size         = cc.size(480, 320),
10 dr_policy        = cc.ResolutionPolicy.FIXED_HEIGHT,
11 
12 show_status        = false,
13 
14 animation_interval = 1/60,
15 
16 app                = "game.application",
17 
18 syslog_enabled  = true,
19 syslog_console_enabled = true,
20 syslog_console_printfun = function(str)
21         print(">> syslog " .. str)
22     end,
23 syslog_limit_level = fw.logger.NOSET,
24 
25 syslog_file_enabled = true,
26 syslog_file_autoflush = true,
27 syslog_file_parser = function(str)
28         return fw.encrypt.encrypt(str .. '
')
29     end,
30 syslog_file_dir = fw.platform.get_writable_path() .. "log",
31 syslog_file_path= fw.platform.get_writable_path() .. "log/sys_log",

当然,这份是app配置文件，可以看到在logger写入函数我采用了xxtea加密方式写入,如果在开发期,可以屏蔽掉加密.直接写入就好了.当然也可以不写.好了,就到这里了.

这里是可以添加测试用例的,方法就是修改其中的app属性配置,从app.lua继承实现一个自己的test_application,然后修改配置文件，启动的时候就切换了入口.看需求添加吧,如果是有独立封装的ui类库以及其他独立功能可以考虑添加测试用例.又或者是需要添加工具,也可以在这里做考虑。

这次的文章篇幅比较的长,希望大家耐心点看. 终于我算是完成了自己的承诺了. 嘻嘻嘻嘻嘻~
