: This article mainly introduces the nginx source code learning notes (21) -- event Module 2 -- the event-driven core ngx_process_events_and_timers. if you are interested in the PHP Tutorial, refer to it. First, let's continue to recall that there was a non-involved ngx_process_events_and_timers in the previous sub-thread execution operation. today we will study this function.

[Asp. Net Core] 2. Add controllers and views, asp. netcoreController Before adding a Controller, let's take a look at some controllers that are automatically generated for us. Let's take a look at AccountController. cs Let's take a look at the logon verification method Login. What Should async do asynchronously? What is Task Let's take a look at the following two articles: Dudu:Case study: Use async/a

. now HttpApplication needs to initialize the request processing pipeline to handle the response operations of pages of type ASP. NET WebForm or ASP. It performs its corresponding Init method on each of its httpmodule by reading the information about HttpModule in the Web. config configuration file and passing it to the collection of HttpModule. Next , complete the registration of the HttpApplication 19 pipeline events . All you need now is to invoke the execution method corresponding to each ev

The most important of the naming rules is create rule, which is officially stated as follows:There is a important distinction between Get, and Copy and Create, in names of functions that return values. If You use a Get function, you cannot is certain of the returned object ' s life span. To ensure the persistence of such a object can retain it (using the Cfretain function) or, in some cases, copy it. If you use a Copy or Create function, you is responsible for releasing the object (using the Cfr

course content of Intel, the overall architecture of this course system is not a secret. I want to announce it here. It is helpful for anyone who wants to learn multi-core programming independently. At least you should know that it is complete to cover those points to learn this topic. 1. Basic knowledge about threads and processes. Needless to say. But we need to figure out the relationship between multit

The container uses dependency injection to set bean Attributes Based on the xml configuration file.13 if bean defines the init-method, call this method to perform initialization. 6. Assemble the bean (that is, correctly configure Each bean node in the XML configuration file, and write the bean to XML

the string buffer contains a sequence of characters that does not exceed this capacity, there is no need to allocate a new array of internal buffers. If an internal buffer overflows, this capacity is automatically incremented.Starting with JDK 5, this class complements the equivalence class used by a single thread, StringBuilder. The StringBuilder class should usually be preferred over this class because it supports all the same operations, but it is faster because it does not perform synchroni

Java core programming-byte stream of IO stream (2), javaio 1. byte stream A 1.1-byte stream is a stream that operates byte. Byte streams can operate on any data, such as media data, music, movies, and images. Of course, they can also operate on characters. Byte stream is based on byte stream, we know that a byte is 8 binary bits, a byte corresponds to an English character in the UTF-8, people found that usi

business dimension information for integrated integration, this situation is more appropriate for generating surrogate keys to master keys. Summary The construction of the dimension table seems relatively simple, in most cases the business library will be directly, but in addition to the different levels of the dimension of Redundancy (Star model), but also need to grasp the details of the following dimensions of the construction of attention, after all, the dimension of errors will

1, Stage: Virtual parallel task set, all tasks on the same Stage have the same shuffle dependency. The stages are divided according to the shuffle mark. One stage with multiple Rdd, first with an rdd and one stage with multiple task stages through Shuffledependency division, one stage is narrowdependency stage type There are two kinds, shufflemapstage and Resultstage. -Shufflemapstage The result of this phase task is the input to the next stage task. You need to keep track of the no
