The reason for the deadlock is generally the two-object lock waiting for each other.
In the article "Java Thread: Thread synchronization and lock", the concept and simple example of deadlock are briefly described, but the given example is incomplete, and here is a complete example.

Recently, many people have to collaborate on github, that is, multi-person development. I searched some documents, which were the same and difficult to operate. Today, let's take a look at the simple implementation of github's multi-person collaboration.

-person collaboration is usually as follows:
First, you can try to useGit push origin branch-namePush your own changes;
If the push fails, you must useGit pullTry to merge;
If a merge conflict exists, the conflict is resolved and submitted locally;
After no conflict or resolution, useGit push origin branch-namePush is successful!
IfGit pullIf "no tracking information" is displayed, the link between the local branch and the remote branch is not c
started a variety of projects with the names of animal S, Apache Pig being the most well known. As we were talking about different possible names, one of the group members mentioned that we should avoid another animal Name because our manager thought it is starting to the sound as we lived in a zoo. That was when it clicked:distributed systems was a zoo. They was chaotic and hard to manage, and ZooKeeper was meant to keep them under control.The Cat on the book cover is also appropriate, because

Project collaboration and WorkflowSpecificationAs the saying goes, if you do not know why to do so, what good, even if the specification will not be a good implementation of the ground. Here's a discussion of what the specification and specification solves, and what the solution is:1, the project can call each other, can be extended Problem:Your project may be called by another project, if there are no specifications and documents, other items cannot
What is Zookeeperis an open source, distributed, Apache project that provides collaborative services for distributed applicationsProvides a simple set of primitives so that with distributed applications can build higher-level synchronization services on top of himThe design is very simple and easy to program, and he uses a tree-like data structure similar to that of a file system.The goal is to have distributed services no longer need to have collaboration
Recently in the project development process found that the team collaboration problem, itself is a small team of 3 people, but reflects the problems of some large teams.Project development process, the front-end project and the business logic layer by two programmers to do, but each has their own customary practice and code style, although all can realize the function, but to integrate the project, the overall process of testing, but found that the in
As a source code management system, Git inevitably involves the collaboration of many people.Cooperation must have a normative process, so that everyone effectively cooperate, so that the project is well-organized development. "Collaborative process" in English, called "Workflow" or "flow", is intended to be a water flow, the analogy of the project as the flow of water, smooth, natural flow forward without impact, collision, or even vortex.This articl

Multi-thread collaboration in Java is a common practice. As we all know, such collaboration is mostly implemented through wait (), notify (), or yyall, however, this implementation is worth noting. See the following example:
Thread1: synchronized (sharedmonitor) {somecondition = false; sharedmonitor. running y ();} thread2: While (somecondition) {// point 1 synchronized (sharedmonitor) {sharedmonitor.
