Thrift's go and C language implementations
Thrift 是Facebook为了解决各系统间大数据量的传输通信以及系统之间语言环境不同而设计的一种传输框架。目前来看常用的主流语言Thrift都已经很好地支持,并且github上已经有很多实现,除了C语言之外。Thrift传输的程序的静态数据,即数据的数据结构必须事前固定。Thrift原理就不介绍了,理论性东西网上很多,并且都是雷同的。下面通过实例介绍Thrift 接口在Go与C语言下的实现,以及如何在C语言中调用Go所编写的Thrift客户端。
1. Thrift File Preparation
#example.thrift namespace go thrift.rpc struct Response { 1: required string data; }service RpcService {
Xrange (1, 9) will create a generator object. We can modify the foreach line to print out the Xrange object and see
... $xrange _res = xrange (1, 9); Var_dump ($xrange _res); foreach ($xrange _res as $number) {...
Output
As you can see, the execution of xrange (1, 9) did return a generator object.
Use the Send method of the Generator object
In the example above, we use the yield statement as a separate line of statements, that is, the yield statement produces the result to the outside, t
count=14 (this number is not fixed), as to why it is 14 or other numbers, you need to judge according to the GC log 5. Method Area:The method area is also shared by all threads. It is mainly used for storing class information, Chang, method data, method code and so on.Second, HotSpot VMIn the process of learning the JVM, the most confusing concept is the partition of the memory area in the JVM specification and the partition of the JVM memory area in the JVM implementation, there is a mapping

Yesterday, a netizen said that the computer's AntiVir constantly reported that the virus was working very slowly and asked him to repair it through QQ.
Check the log of AntiVir, as shown in the following figure (duplicate virus items are removed ):/---Exported events:

Upgrade the official 5.03 system to a self-built system, such as 5.03 Prometheus 3
Installation instructions:
1.This system targetsPSP 3000/2000 v3User, and like GEN-C, currently only available on PSP 3000 host and the Official System Version cannot be higher5.03.
2. The attack method is also based on the image scalping vulnerability. The attack sequence is to shut down completely, read the image vulnerability, and then run the system.

First, download the protobuf-gen-Lua plug-in. The plug-in git address is here.
After the download, go to the protoc-gen-Lua \ plugin directory and create a batch file:

The original text is as follows:
I use C ++, so I will give a C ++ example to briefly introduce thrift's getting started.
The example is described as follows: the student information (student ID, name, gender, age) is sent to the server by the client.
To implement this example, we have to do the following:
(1) write the. Thrift File
(2) generate a CPP File
(3) Compile the client
(4) Compile and execute the CPP File
and cleaned:

After the release of Tornado3, the concept of coroutine was strengthened, and in asynchronous programming, it replaced the original Gen.engine and became the present gen.coroutine. This decorator is intended to simplify asynchronous programming in tornado. Avoid writing callback functions that make development more consistent with normal logical thinking. A simple example is as follows:
Class Maindhandler (web. RequestHandler):

changes the nature of the function: yield statements do not have to be invoke or even accessible. But the function is turned into a generator. When a function is called, its commands are executed. When a generator is called, the execution stops before the first command. Create a generator object attached to the iteration protocol by calling the generator. Like conventional functions, concurrent and recursive calls are allowed.When next is called, the function is executed to the first yield. Eac

Tornado is used asynchronously, and a simple asynchronous crawling class is obtained according to the example modified in the official document.

performs GC according to Generation (generation), which is divided into young generation (younger generation), tenured generation (old age), permanent generation (permanent generation), as shown in the figure below. Perm Gen), Perm Gen (or non-heap non-heap) is a heterogeneous one that will be described later. Note that the heap space does not include Perm Gen.
IPFs Private Network setup:
1. Prepare at least 2 IPFs nodes
2. Create a shared secret key
3. Configure the nodes that need to be shared with each other.
First, prepare the IPFs node.
1, prepare two Linux nodes, I test the system is Ubuntu 18.04 LTS (click can download).
2, install the IPFs command: (if installed can Shanghai aluminum ignore)
sudo snap install IPFs
3, install the Go-lang environment, the subsequent creation of the shared secret key needs to use. (if installed, ignore)
sudo apt-g

If the generator is complete but no result is returned, null is returned.
