�?C++ 中��?Python script

Thu, 14 Aug 2008 09:55:00 GMT

惌��在c++ 中嵌入script 代码, 除了自己写脚本引擎外, lua, python 都可以在c++ 中��? 另外 MonoBind, AngelScript library 都是一些c++ script library, 可以嵌入到c++ 中��?.
今天在c++ 中试着嵌入 python 代码 (�C�Z��代码�?Python-2.5.2\Demo\embed\ �?

#include <Python.h>
int main(int argc, char *argv[])
{
  // Py_NoSiteFlag = 1;
  // Py_SetPythonHome("D:\\usr\\Python"); // PYTHONHOME

  Py_Initialize();
  PyRun_SimpleString("from time import time,ctime\n"
                     "print 'Today is',ctime(time())\n");
  Py_Finalize();
  return 0;
}

在运行时可能会��生类�?'import site' failed; use -v for traceback 的错�? 原因是python 在import module 的时候的路径问题. �?�U�方法可以解�?以前通过讄��环境变量 PYTHONPATH 好像�?.5 已经无效�?.
0. 取消注释 Py_NoSiteFlag = 1;
�q�个只是取消import site , 当然如果在代码中要import 啥的�? �q�是会出现错误的.
a. 讄��环境变量 PYTHONHOME = D:\usr\Python
b. 在调�?Py_Initialize 之前调用函数
Py_SetPythonHome("D:\\usr\\Python"); // 参数是python 的安装目�?

2. 其他一些有用的资源
Python/C API Reference Manual (API 参�? , Extending and Embedding the Python Interpreter (扩展及嵌入Python解释�? 主要说明了如何扩展Python, �l�Python 写扩�? 其中 5. Embedding Python in Another Application 一章讲�q�C��在C++中嵌�?调用Python 代码 )

http://hi.baidu.com/yunsweet/blog/item/20b08aeebaa2b1282cf534c7.html

3. Python 多线�E�的使用

zz http://blog.csdn.net/liguangyi/archive/2007/06/20/1659697.aspx
今天看了�q�一天关于多�U�程的应用中�Q�如何安全调用python斚w��的资料，开始的时候看的简直头大如斗，被python语言的全局�?Global Interpreter Lock)、线�E�状�?Thread State )�{�都有点�l�晕了，后来�l�过各方面文章和帮助文档的相互参考，发现对于2.4/2.5版本�Q�提供了PyGILState_Ensure, PyGILState_Release�Q�哎�Q�这下可方便大发了�?/p>

一、首先定义一个封装类�Q�主要是保证PyGILState_Ensure, PyGILState_Release配对使用�Q�而且�q�个�c�L��可以嵌套使用的�?/p>

#include

class PyThreadStateLock
{
public:
    PyThreadStateLock(void)
    {
        state = PyGILState_Ensure( );
    }

    ~PyThreadStateLock(void)
    {
         PyGILState_Release( state );
    }
private:
    PyGILState_STATE state;
};

二、在�ȝ��E�中�Q�这样处�?/p>

    // 初始�?br>    Py_Initialize();
    // 初始化线�E�支�?br>    PyEval_InitThreads();
    // 启动子线�E�前执行�Q��ؓ了释放PyEval_InitThreads获得的全局锁，否则子线�E�可能无法获取到全局锁�?br>    PyEval_ReleaseThread(PyThreadState_Get());

    // 其他的处理，如启动子�U�程�{?br>    ......

    // 保证子线�E�调用都�l�束�?br>    PyGILState_Ensure();
    Py_Finalize();
    // 之后不能再调用�Q何python的API

三、在�ȝ��E�，或者子�U�程中，调用python本��n函数的都采用如下处理

    {
        class PyThreadStateLock PyThreadLock;
        // 调用python的API函数处理
        ......
    }

呵呵�Q�看�q�样是否非常��单了�?/p>

另外�q�有两个和全局锁有关的宏，Py_BEGIN_ALLOW_THREADS �?Py_END_ALLOW_THREADS。这两个宏是��Z��在较长时间的C函数调用前，临时释放全局锁，完成后重新获取全局锁，以避免阻塞其他python的线�E��l�运行。这两个宏可以这栯��?/p>

    {
        class PyThreadStateLock PyThreadLock;
        // 调用python的API函数处理
        ......

        Py_BEGIN_ALLOW_THREADS
        // 调用需要长旉��的C函数
        ......
        Py_END_ALLOW_THREADS

        // 调用python的API函数处理
        ......
    }

4. 可能的错误及解决
a. 在vs 200x �?debug 模式出现链接问题
extmodule.obj : error LNK2019: unresolved external symbol __imp___Py_Dealloc referenced in function _PySwigObject_format
extmodule.obj : error LNK2019: unresolved external symbol __imp___Py_NegativeRefcount referenced in function _PySwigObject_format
extmodule.obj : error LNK2001: unresolved external symbol __imp___Py_RefTotal
extmodule.obj : error LNK2019: unresolved external symbol __imp___PyObject_DebugFree referenced in function _PySwigObject_dealloc
extmodule.obj : error LNK2019: unresolved external symbol __imp___PyObject_DebugMalloc referenced in function _PySwigObject_New
extmodule.obj : error LNK2019: unresolved external symbol __imp__Py_InitModule4TraceRefs referenced in function _init_extmodule

主要是因�?Py_DEBUG/Py_TRACE_REFS 引�v, 修改 Python\include 下的 pyconfig.h, object.h 两个文�g��p��?... 详见 http://www.nabble.com/link-error-in-debug-mode-td3126668.html

使用 python �?COM

Thu, 14 Aug 2008 09:02:00 GMT

Python 支持Com调用(client com) 以及撰写COM �l��g(server com).
1. com 调用�C�Z��(使用Windows Media Player 播放音乐)

from win32com.client import Dispatch
mp = Dispatch("WMPlayer.OCX")
tune = mp.newMedia("C:/WINDOWS/system32/oobe/images/title.wma")
mp.currentPlaylist.appendItem(tune)
mp.controls.play()

2. com server 的编�?br>主要可以参�?<<Python Programming on Win32 �?Chapter 12 Advanced Python and COM http://oreilly.com/catalog/pythonwin32/chapter/ch12.html >>
�C�Z��(分割字符�?
- 代码

class PythonUtilities:
    _public_methods_ = [ 'SplitString' ]
    _reg_progid_ = "PythonDemos.Utilities"
    # NEVER copy the following ID
    # Use "print pythoncom.CreateGuid()" to make a new one.
    _reg_clsid_ = "{41E24E95-D45A-11D2-852C-204C4F4F5020}"

    def SplitString(self, val, item=None):
        import string
        if item != None: item = str(item)
        return string.split(str(val), item)

# Add code so that when this script is run by
# Python.exe, it self-registers.
if __name__=='__main__':
    print "Registering COM server"
    import win32com.server.register
    win32com.server.register.UseCommandLine(PythonUtilities)

- 注册/注销Com

Command-Line Option	Description
	The default is to register the COM objects.
`--unregister`	Unregisters the objects. This removes all references to the objects from the Windows registry.
`--debug`	Registers the COM servers in debug mode. We discuss debugging COM servers later in this chapter.
`--quiet`	Register (or unregister) the object quietly (i.e., don't report success).

- 使用COM
可以在python 命��o行下�q�行

>>> import win32com.client
>>> s = win32com.client.Dispatch("PythonDemos.Utilities")
>>> s.SplitString("a,b,c", ",")
((u'a', u'a,b,c'),)
>>>

3. python server com 原理
其实在注册表中查扑ֈ�python com 的实现内�q?

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\CLSID\{41E24E95-D45A-11D2-852C-204C4F4F5020}]
@="PythonDemos.Utilities"

[HKEY_CLASSES_ROOT\CLSID\{41E24E95-D45A-11D2-852C-204C4F4F5020}\Debugging]
@="0"

[HKEY_CLASSES_ROOT\CLSID\{41E24E95-D45A-11D2-852C-204C4F4F5020}\Implemented Categories]

[HKEY_CLASSES_ROOT\CLSID\{41E24E95-D45A-11D2-852C-204C4F4F5020}\Implemented Categories\{B3EF80D0-68E2-11D0-A689-00C04FD658FF}]

[HKEY_CLASSES_ROOT\CLSID\{41E24E95-D45A-11D2-852C-204C4F4F5020}\InprocServer32]
@="pythoncom25.dll"
"ThreadingModel"="both"

[HKEY_CLASSES_ROOT\CLSID\{41E24E95-D45A-11D2-852C-204C4F4F5020}\LocalServer32]
@="D:\\usr\\Python\\pythonw.exe \"D:\\usr\\Python\\lib\\site-packages\\win32com\\server\\localserver.py\" {41E24E95-D45A-11D2-852C-204C4F4F5020}"

[HKEY_CLASSES_ROOT\CLSID\{41E24E95-D45A-11D2-852C-204C4F4F5020}\ProgID]
@="PythonDemos.Utilities"

[HKEY_CLASSES_ROOT\CLSID\{41E24E95-D45A-11D2-852C-204C4F4F5020}\PythonCOM]
@="PythonDemos.PythonUtilities"

[HKEY_CLASSES_ROOT\CLSID\{41E24E95-D45A-11D2-852C-204C4F4F5020}\PythonCOMPath]
@="D:\\"

inproc server 是通过pythoncom25.dll 实现
local server 通过localserver.py 实现
com 对应的python 源文件信息在 PythonCOMPath & PythonCOM

4. 使用问题
用PHP 或�?c 调用com 的时�?br>

php
$com = new COM("PythonDemos.Utilities");
$rs = $com->SplitString("a b c");
foreach($rs as $r)
echo $r."\n";
?>

会碰��C��面的一些错�?
pythoncom error: PythonCOM Server - The 'win32com.server.policy' module could not be loaded.
: No module named server.policy pythoncom error: CPyFactory::CreateInstance failed to create instance. (80004005)

可以通过2�U�方式解�?
a. 讄��环境 PYTHONHOME = D:\usr\Python
另外在c ++ 使用python 的时�? 如果import module 出现错误 'import site' failed; use -v for traceback 的话, 也可以通过讄��q�个变量解决.

b. 为com 生��exe, dll 可执行文�? setup.py 代码如下 :

from distutils.core import setup
import py2exe

import sys
import shutil

# Remove the build tree ALWAYS do that!
shutil.rmtree("build", ignore_errors=True)

# List of modules to exclude from the executable
excludes = ["pywin", "pywin.debugger", "pywin.debugger.dbgcon", "pywin.dialogs", "pywin.dialogs.list"]

# List of modules to include in the executable
includes = ["win32com.server"]

# ModuleFinder can't handle runtime changes to __path__, but win32com uses them
try:
    # if this doesn't work, try import modulefinder
    import py2exe.mf as modulefinder
    import win32com

    for p in win32com.__path__[1:]:
        modulefinder.AddPackagePath("win32com", p)

    for extra in ["win32com.shell", "win32com.server"]: #,"win32com.mapi"
        __import__(extra)
        m = sys.modules[extra]
        for p in m.__path__[1:]:
            modulefinder.AddPackagePath(extra, p)

except ImportError:
    # no build path setup, no worries.
    pass

# Set up py2exe with all the options
setup(
    options = {"py2exe": {"compressed": 2,
                          "optimize": 2,
                          #"bundle_files": 1,
                          "dist_dir": "COMDist",
                          "excludes": excludes,
                          "includes": includes}},
    # The lib directory contains everything except the executables and the python dll.
    # Can include a subdirectory name.
    zipfile = None,
    com_server = ['PythonDemos'], # 文�g�?!
    )
