Question 1: What does hot update mean? The simplest explanation is to update directly without turning off the software. During the update period, the software is used directly. Most of the software now is a cold update, and you have to exit to update.

Question 2: What does ios hot update mean? Why should ios be removed? The popularity of hot update ISO10 has not passed yet, iOS10.2 Beta3 has been launched. So everyone must want to know what is updated in iOS10.2? How about ios10.2? What I bring to you below is a detailed introduction to iOS10.2 Beta3. Friends who are interested should come and take a look! Introduction to iOS10.2 Beta3 iOS10.2 developer preview version Beta3 firmware update, this is the third developer preview version of iOS10.2. In addition, iOS10.2 public beta version Beta3 is also pushed simultaneously. As usual, two versions are updated. The content is the same. The firmware number of this update is 14C5077b. iOS10.2 Beta3 function In iOS 10.2 beta 3, Apple has deleted the video App (due to the emergence of TV App). The notification plug-in for video applications in iOS 10.1 has also been deleted. Removed and replaced by the notification plug-in used by TV. In this version, Apple has removed the SOS emergency call function. You can call the emergency service function by pressing the power button multiple times. In Apple's release notes Speaking of, the SOS function is currently only available in India. The iOS10.2 Beta3 update content SOS emergency rescue function has been removed, which is only available in the Indian region. Video applications have been removed, and video application notification plug-ins have been removed. TV applications (National Bank name) ), users can choose whether to use data to play videos. Users can choose HD or SD image quality when purchasing video resources. Currently, the Chinese version cannot be used and needs to be switched to the US region to experience it. iMessage has added a new love full-screen special effect.

I think this article is helpful to everyone. If you have any questions, please leave a message below!

Question 3: What does the hot update of Apple mobile phones mean? Please answer in detail. It means updating directly within the application without going through the APP store. For example, some games often update data packages.

Question 4: Is hot update really that important? Background I believe that students who have used Node.js for web applications must have been troubled by the problem that the newly modified code must restart the Node.js process before it can be updated. Students who are accustomed to using PHP will find it very inapplicable. As expected, PHP is the best programming language in the world. Manually restarting the process is not only a very annoying duplication of work, but when the application scale becomes larger, the startup time gradually begins to become unignorable. Of course, as a programmer, no matter which language you use, you will not let such things torture you. The most direct and universal way to solve this kind of problem is to monitor file modifications and restart the process. This method has also been provided by many mature solutions, such as the abandoned node-supervisor, the now popular PM2, or the relatively lightweight node-dev, etc., which are all based on this idea. This article provides another idea. With only a small modification, you can achieve true zero-restart hot update code and solve the annoying code update problem in Node.js web applications. Overall idea: Speaking of code hot update, the most famous one at the moment is the hot update function of the Erlang language. This language is characterized by high concurrency and distributed programming. Its main application scenarios are fields such as securities trading and game servers.

These scenarios more or less require services to have means of operation and maintenance during operation, and code hot updating is a very important part of it, so we can first briefly take a look at Erlang's approach. Since I have never used Erlang, the following content is all hearsay. If you want to have an in-depth and accurate understanding of Erlang's code hot update implementation, it is best to consult the official documentation. Erlang's code loading is managed by a module called code_server. Except for some necessary code at startup, most of the code is loaded by code_server. When code_server finds that the module code has been updated, it will reload the module. New requests thereafter will be executed using the new module, while requests that are still executing will continue to be executed using the old module. The old module will be labeled old after the new module is loaded, and the new module will be labeled current. During the next hot update, Erlang will scan and kill the old modules that are still executing, and then continue to update the modules according to this logic. Not all codes in Erlang allow hot updates. Basic modules such as kernel, stdlib, piler and other basic modules are not allowed to be updated by default. We can find that Node.js also has modules similar to code_server, that is, the reuire system, so Erlang's approach should also be possible. Try some things on Node.js. By understanding Erlang's approach, we can roughly summarize the key issues in solving code hot updates in Node.js: how to update the module code, how to use the new module to process requests, how to release the resources of the old module. Then we will analyze these one by one. Problem spot. How to update module code To solve the problem of module code update, we need to read the module manager implementation of Node.js and directly link to module.js. Through simple reading, we can find that the core code lies in Module._load. Let’s simplify the code and post it. Check the cache for the reuested file. 1. If a module already exists in the cache: return its exports object. 2. If the module is native: call `NativeModule.reuire()` with the filename and return the result. 3. Otherwise, create...gt;gt;

Question 5: What is hot update? There is no need to shut down the server during hot update, just redeploy the project directly. Of course, the cold one is to shut down the server before operating.

Question 6: What does android hot update mean? We know that Java loads the corresponding class at runtime through ClassLoader. ClassLoader itself is an abstraction. Android The PathClassLoader class is used as Android's default class loader.

PathClassLoader actually implements simply loading class files from the file system.

PathClassLoade itself inherits from BaseDexClassLoader. BaseDexClassLoader overrides the findClass method.

This method is the core of ClassLoader.

Question 7: How important hot updates are is probably a bit over-the-top. No. If you know how old your baby is, you can boil some radish water for him to drink. Don’t put too many clothes on him. The same goes for food. Try not to eat foods that can cause irritation.

Question 8: What does hot update mean? It’s just that the update is relatively hot

Question 9: How to implement iOS hot update Unity does not implement hot update of iOS platform code because:

1 The so-called hot update means that the code can not be repackaged Submit it to the App Store to update the client's execution code.

2 Due to the following reasons, client updates are expected to be lighter and faster: the App Store review cycle is difficult to control; mobile online games are updated frequently.

Question 10: Is hot update really that important? Japanese products are not safe, and Korean products are not as good as Japanese products. Of course, if you can find the exceptions that are made in Japan and South Korea rather than in China, people are not sure about China. The market is treated specially.

ESP is very necessary for security. Don’t be afraid of ten thousand, just be afraid of the unexpected. What do you think? The 2010 Volkswagen GOLF is standard equipment, the Volkswagen Skoda Octavia manual version is also standard equipment, and the manual version of the lowest-end model with more than 120,000 yuan can be optional.
