笔记：Ubuntu下快速开始使用Python Thrift

本文介绍如何在Ubuntu 10.04下安装Apache Thrift并用Python写一个Demo。

apt-get install libboost-dev libevent-dev python-dev automake pkg-config libtool flex bison sun-java6-jdk
wget http://www.apache.org/dist//thrift/0.8.0/thrift-0.8.0.tar.gz
tar zxvf thrift-0.8.0.tar.gz
cd thrift-0.8.0
./configure
make
sudo make install
sudo pip install thrift

编辑接口文件 hellowworld.thrift:

service HelloWorld {
    string ping(),
    string say(1:string msg)
}

编辑 server.py

#!/usr/bin/env python
 
import socket
import sys
sys.path.append('./gen-py')
 
from helloworld import HelloWorld
from helloworld.ttypes import *
 
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
from thrift.server import TServer
 
class HelloWorldHandler:
  def ping(self):
    return "pong"
 
  def say(self, msg):
    ret = "Received: " + msg
    print ret
    return ret
 
handler = HelloWorldHandler()
processor = HelloWorld.Processor(handler)
transport = TSocket.TServerSocket("localhost", 9090)
tfactory = TTransport.TBufferedTransportFactory()
pfactory = TBinaryProtocol.TBinaryProtocolFactory()
 
server = TServer.TSimpleServer(processor, transport, tfactory, pfactory)
 
print "Starting thrift server in python..."
server.serve()
print "done!"

编辑 client.py

#!/usr/bin/env python
 
import sys
sys.path.append('./gen-py')
 
from helloworld import HelloWorld
 
from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
 
try:
  transport = TSocket.TSocket('localhost', 9090)
  transport = TTransport.TBufferedTransport(transport)
  protocol = TBinaryProtocol.TBinaryProtocol(transport)
  client = HelloWorld.Client(protocol)
  transport.open()
 
  print "client - ping"
  print "server - " + client.ping()
 
  print "client - say"
  msg = client.say("Hello!")
  print "server - " + msg
 
  transport.close()
 
except Thrift.TException, ex:
  print "%s" % (ex.message)

thrift --gen py helloworld.thrift
python server.py
python client.py

Installing C++ 4.8.5 on CentOS 6.7

With yum on CentOS, the most updated gcc version are
gcc 4.1.2 for CentOS 5
gcc 4.4.7 for CentOS 6
gcc 4.8.5 for CentOS 7

What if you want to have higher version to run on CentOS 6? This article is going to tell you how to compile gcc on CentOS 6.7 which is the final version of CentOS.

First you are going to download CentOS 6.7 DVD1 ISO file.
http://centos.uhost.hk/6.7/isos/x86_64/CentOS-6.7-x86_64-bin-DVD1.iso

I used VMWare Workstation 12 Player to host the virtual machine. As it supports "Linux Easy Install", simply mount the ISO to a newly created VM, start it to enter user name and password. After 15 minutes, it will bring you to the Linux installed environment.

Install gcc compiler
First thing to to is to use terminal to install the most updated compiler. It will be used to compile the new compiler. Yes. gcc is compiled using its gcc compiler.
sudo yum install gcc-c++

Install glibc
sudo yum install -y gcc texinfo-tex flex zip libgcc.i686 glibc-devel.i686

Download gcc source code
wget ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.5/gcc-4.8.5.tar.gz

Download mpc, mpfr, gmp package
tar zxf gcc-4.8.5.tar.gz
cd gcc-4.8.5
./contrib/download_prerequisites

Compile gcc
mkdir gcc-build-4.8.5
cd gcc-build-4.8.5
../configure --prefix=/usr
sudo make && make install

Check your gcc versions
gcc --version
gcc (GCC) 4.8.5
g++ --version
g++ (GCC) 4.8.5
which gcc
/usr/bin/gcc
which g++
/usr/bin/g++

After 2 hours of compilation, you will be able to see the below installed log.

Test the compilation:

cat >test.cc <<EOF
#include <iostream>
using namespace std;
int main() {
cout << "Hello, World!" << endl;
return 0;
}
EOF

g++ -o test.exe -g -Wall test.cc

./test.exe

Hello, World!

Check rpm installed
Because you are compiling gcc on your own, yum or rpm are unware of the new gcc version.
rpm -qa | grep gcc

gcc-4.4.7-16.el6.x86_64
libgcc-4.4.7-16.el6.x86_64
libgcc-4.4.7-16.el6.i686
gcc-c++-4.4.7-16.el6.x86_64

robot framework 使用五：CentOS上运行robot framework 并自动发送测试结果

http://blog.csdn.net/mask5726/article/details/27520041

操作系统版本：centos 6.0 x86_64

想要在linux上运行robot framework的测试用例，需要安装以下工具和软件：

1.安装python 2.7.6 ，首先python --version 查看系统是否装有python，并且python的版本是不是我们要用的

Python 2.6.5

说明已经装有python 2.6.5，下载python2.7.6，下载地址：https://www.python.org/download#pubkeys 选择：Python 2.7.6 compressed source tarball (for Linux, Unix or Mac OS X)

使用root用户登录，下载后的文件通过rz命令将文件Python-2.7.6.tgz上传到root用户目录下

 执行以下命令安装：

tar zxvf Python-2.7.6.tgz

3cd Python-2.7.6

4./configure --prefix=/usr/local

5make && make altinstall

安装完后执行：python2.7 --version

出现这个：Python 2.7.6

证明安装完成，安装的目录为：/usr/local/lib/python2.7

为便于和系统中的python2.6.5区分，运行python的时候用python2.7代替。

2.安装 robotframework-2.8.4.tar.gz ,下载地址：https://pypi.python.org/pypi/robotframework

通过rz命令上传到root用户根目录下，执行 tar -zxvf robotframework-2.8.4.tar.gz

cd robotframework-2.8.4

python setup.py install

安装完成后，运行pybot --version

出现：Robot Framework 2.8.4 (Python 2.7.6 on linux2)

表明安装成功。

3.安装selenium2library和其他需要的库

执行

easy_install-2.7 robotframework-selenium2library

easy_install-2.7 selenium

easy_install-2.7 decorator

然后验证

python2.7
Type "help", "copyright", "credits" or "license" for more information.
>>> import Selenium2Library
>>>

出现最后那个空行表明安装成功！

先安装ez_setup.py,下载地址：https://pypi.python.org/pypi/setuptools/#unix-wget

执行 python2.7 ez_setup.py

4.把我们的脚本目录test传到linux上，执行 pybot ./cases.txt 或者python -m robot.run ./test，即可运行。

5.linux上运行脚本，需要有display，解决办法是安装vnc或者xvbf，vns安装：

yum -y groupinstall “X Window System” “Desktop” “Fonts” “General Purpose Desktop”

rpm -ivh /mnt/Server/vnc-server-4.1.2-9.el5.x86_64.rpm

service vncserver start

vncserver :1

启动vncserver之后会提示输入初始密码，输入并确认后就可以在windows机器上下载http://www.realvnc.com/download/登陆到这个Linux机器上用鼠标操作

我的机器vncserver装完后不能正常工作，所以采用第二种方式，安装 xvbf

yum -y install xorg-x11-server-Xvfb

yum -y install mesa-dri-drivers

dbus-uuidgen –ensure

执行：Xvbf后就可以成功运行脚本了，需要主要脚本的命名最好用英文。

下一篇再介绍如何自动执行测试用例和自动发送结果邮件吧。

C++ explicit call of operator new and delete

Below Code is equvalent:

{
A * a = new A;
delete a;
}
{
A * a = (A*)(::operator new(sizeof(A)));
a->A::A();
a->~A();
::operator delete(a);
}

#include <iostream>
#include <list>
#include <allocators>
class A
{
public:
A(){std::cout << " A()\n";}
~A(){std::cout << "~A()\n";}
};
int main()
{
using namespace std;
{
A * a = new A;
delete a;
}
{
A * a = (A*)(::operator new(sizeof(A)));
a->A::A();
if (a!=0)
{
a->~A();
::operator delete(a);
}
}
return 0;
}
