frog對象定義了小動物的某些屬性，訪問frog對象屬性時，通過 dict,list的取值方法進行訪問，例如:

數據編碼采用json或者xml
以com方式提供生產系統訪問接口，直覺告訴我實現會有點問題，那就是python+Qt做com組件，這個組件與影像系統通信，
com組件訪問顯示qt的ui界面會存在問題，沒有做過嘗試，不知是否能行
Com方式提供服務采用獨立服務器模式還是獨立的組件模式(其實是個線程模型問題，獨立進程的com server還是加載到應用app進程的com object)
花點時間琢磨去........

運氣來了，無意之間找到個pyglet的項目里面有個tools/wrap.py的東西，還是個式樣性質的東西，并沒有在他的發行代碼中，但可訪問他的svn可以獲取到，wrap.py輸入一個.h的文件便可自動生成對應的數據結構，試了一下avcodec.h，立馬出來個avcodec.py,爽啊

今天空下來就用python開始編寫自動備份方案：
1.http自動登錄
2.wget斷點下載
3.7zip壓縮
4.網盤 everbox的同步到服務器
與http server的交互信息用wireshark抓包分析，還蠻靈光的
python代碼：
1 # -*- coding:utf-8 -*-
2 #auto backup system database
3 #自動登錄，http下載，壓縮之后通過網盤同步到服務器

BaseServer: 定義基礎服務器接口，這些功能接口提供給子類繼承。同時提供服務處理的骨架
serve_forever() 循環調用 handle_request()
handle_request() 調用子類的get_request() ，在tcpServer時實則進行accept()應答; 驗證處理 verify_request();
最終處理請求 process_request()，
verify_request() 虛函數
process_request() 虛函數，這個函數并沒有直接在BaseServer的子類TcpServer中被重載，而是在TcpServer的派生類中通過另一個父類來實
現，比如 ThreadingTCPServer的基類ThreadingMixIn.process_request()實現了此功能函數
finish_request(request, client_address) 執行一次完整的socket數據讀入處理，如果是ThreadMixInTcpServer產生的request，這個方法內必須實行循環讀取socket數據,直到socket關閉。(此處 request 就是 socket對象)
def finish_request(self, request, client_address):
"""Finish one request by instantiating RequestHandlerClass."""
self.RequestHandlerClass(request, client_address, self)
在finish_request里面便將讀取socket數據的任務扔給了RequestHandler去處理了，代碼可以跳過去看了"""Finish one request by instantiating RequestHandlerClass."""
self.RequestHandlerClass(request, client_address, self)
##---------------------------------------------
TcpServer: tcp服務器
__init__(self, server_address, RequestHandlerClass) 需要提供服務偵聽地址和請求處理類對象
server_bind() 綁定服務器地址
server_activate() 激活服務器
server_close() 關閉服務器
fileno() 返回服務器socket的句柄fd編號
get_request() 接收應答accept()
close_request(request) 關閉socket,request即為socket對象
三種輸出處理方式: 阻塞方式、線程處理(ThreadingMixIn)、進程處理(ForkingMixIn)
ThreadingMixIn: 線程模型
process_request( request, client_address) 為請求的鏈接創建新的線程,在創建線程時直接指定線程入口和參數:
import threading
t = threading.Thread(target = self.process_request_thread,
args = (request, client_address))
if self.daemon_threads:
t.setDaemon (1)
process_request_thread() 線程處理socket入口，負責接收數據，代碼實現有點繞，看看代碼t = threading.Thread(target = self.process_request_thread,
args = (request, client_address))
if self.daemon_threads:
t.setDaemon (1)
def process_request_thread(self, request, client_address):
try:
self.finish_request(request, client_address)
self.close_request(request)
except:
self.handle_error(request, client_address)
self.close_request(request)
ThreadingMixIn其實就是線程代理，還是調用finish_request()進入處理tcp數據的循環，處理完成便close_request()。但是finish_request和close_request并未在ThreadingMinxIn內定義，在哪里呢？ 通過研讀ThreadingTcpServer,原來通過ThreadingTcpServer這個finish_request又跑回了BaseServer.finish_request()try:
self.finish_request(request, client_address)
self.close_request(request)
except:
self.handle_error(request, client_address)
self.close_request(request)
ThreadingTCPServer(ThreadingMixIn, TCPServer) 裝配成線程池處理的tcp服務器
BaseRequestHandler: 請求處理基礎對象，提供統一的行為接口實現處理socket數據。 BaseRequestHandler比較好玩，在構造函數內完成了所有的操作，見代碼：
def __init__(self, request, client_address, server):
self.request = request
self.client_address = client_address
self.server = server
try:
self.setup()
self.handle()
self.finish()
finally:
sys.exc_traceback = None # Help garbage collection
setup()對應的子類會進行初始化處理self.request = request
self.client_address = client_address
self.server = server
try:
self.setup()
self.handle()
self.finish()
finally:
sys.exc_traceback = None # Help garbage collection
self.handle() 直接調用子類的處理函數，可以參考 BaseHTTPRequestHandler(SocketServer.StreamRequestHandler)::handle()
StreamRequestHandler(BaseRequestHandler) 流式socket處理類
setup() 設置好socket對象和讀寫文件句柄 rfile/wfile
HTTPServer(SocketServer.TCPServer) http服務器
BaseHTTPRequestHandler(SocketServer.StreamRequestHandler) 流式的請求處理類
handle() 處理入口，在基類BaseRequestHandle()的構造函數中直接調用
handle_one_request() 如果不是處理一次則返回false。接收一次socket數據，解析parse_request(),調用對應的do_xxx事件
python 的daemon線程：
如果一個進程的主線程運行完畢而子線程還在執行的話，那么進程就不會退出，直到所有子線程結束為止，如何讓主線程結束的時候其他子線程也乖乖的跟老大撤退呢？那就要把那些不聽話的人設置為聽話的小弟，使用線程對象的setDaemon()方法，參數為bool型。True的話就代表你要聽話，我老大（主線程）扯呼，你也要跟著撤，不能拖后腿。如果是False的話就不用那么聽話了，老大允許你們將在外軍命有所不受的。需要注意的是setDaemon()方法必須在線程對象沒有調用start()方法之前調用，否則沒效果。

出現以下異常:
Compiling under Visual Studio .NET v7 recieves the
following error:
_db2_module.c(1855) : error C2036: 'SQLPOINTER' :
unknown size
This can be resolved by casting to (SQLCHAR *) instead
of a (void *):
< SQLPOINTER buf = (SQLPOINTER)((SQLCHAR
*)bs->buf + (bs->bufLen * idx));
發現原來SQLCHAR類型沒有找到，沒問題，找到_db2_module.c:1855行修改為：
SQLPOINTER buf = (SQLPOINTER)((void *)bs->buf +
(bs->bufLen * idx));
再次 setup.py install
ok，編譯成功，db2.py的模塊也被拷貝得到 $PYTHONHOME/lib/site_pakages/下去了
然后安裝db2 client runtime
這樣就完成了pydb2的運行配置。然后就在odbc中配置一個dsn
測試以下代碼：
import DB2
conn = DB2.connect(dsn='sample', uid='db2inst1', pwd='secret')
無異常表示成功連接上DB2
之后訪問數據庫只要遵循python DBI2.0的規范就可以拉！
生活在python世界是很快樂的事情！
*注意: python2.4的話必須用vc7.1編譯pydb2的擴展模塊，因為python2.4(win32)也是用vc7.1編譯的

表操作函數:
ipairs,pairs迭代函數
table.getn(t) len of table
================================================================
function() 可以接受任意多的參數，如果實參數過多將丟棄，過少將默認設置為nil
同樣可以返回多個參數
a,b=foo()
表作為參數傳遞到function
function rename( arg ) os.rename(arg.old,arg.new) end
rename{old="";new=""}
匿名函數(lambda in python )
foo = function(x) return x*2 end
局部函數 local f=function(x) ... end
================================================================
for n=start,end,step do ... end
while b do ... end
repeat do .... until
if then .. elseif then ... end;
有意思的語法表達式:
print a or b or c 如果a=false,嘗試b...

luaL_openlibs(s);
int c = lua_gettop(s);
luaL_dofile(s,"/nandflashpartition/test1.lua");
lua_getglobal(s,"add");

lua_pushnumber(s,8);
if( lua_pcall(s,2,1,0)){
std::cout<< lua_tostring(s,-1)<<std::endl;
}
double r;
r = lua_tonumber(s,-1);
lua_close(s);

lua程序:
function add(x,y)
return x*y
end
--------------------------------
lua訪問c程序空間變量
1.定義變量student.h
extern char * gender;
extern int class_count;
2.創建pkg文件 student.pkg
$#include "student.h"
extern char * gender;
extern int class_count;
3.產生tolua++存根框架
tolua++ -o student.pkg
4.創建lua測試代碼 call_c.lua
print(gender)
print(class_count) 訪問c 空間的變量
5.c測試代碼
char * gender;
int class_count;
void lua_call_c(){
int tolua_student_open (lua_State* tolua_S);
lua_State * s = lua_open();
luaopen_base(s);
gender ="my gender is male!";
class_count = 100;
tolua_student_open(s);
luaL_dofile(s,"/nandflashpartition/call_c.lua");
lua_close(s);
}
6.build && test it!
