During project development, the following problem occurs: This is July. In the same project, I want to develop two modules A and B. Module A is released in July, and Module B is released in July, however, the Code on the trunk (trunk) on SVN must be online. Suppose I can complete these two modules in March, but I cannot develop them on trunk. Because if I have developed these two modules on trunk, how can I ensure that module A will be launched in March? The code I submitted is only for module?

After reading Mark Phippard's blog and Subversion and versioning, I learned that the branch/tag is one of the great features of SVN. But I spent a little time creating my own directory structure using the recommended trunk, branches, and tags folders. This article steps through the creation of a Subclipse project and then establishes a branch. This article assumes that you have installed the Subclipse and c

Gitlab The Master branch is set to protected, the members of the developer identity need to pull a branch separately to develop it, until the stability is later merge into the Master branch, But at this time how do we develop locally according to the developer branch, and how pull developer branches locally, in the pus

First, why we need to use branching-merging. For example, there are two teams under Project demo, and SVN has a trunk version. Because of the sudden change in customer demand, resulting in the project needs to make a large change, at this time the team decided by the Group 1 to continue to complete the work of the original half of the "one module", the group 2 to develop new requirements. So at this point, we can set up a branch for group 2, the

Open the Trunks directory and create a new two text file in the Trunks directory A.java,b.java: Open A.java and enter the following: The B.java file can be entered randomly, and this example is used primarily to observe the subsequent changes. Two file edits are completed with SVN commit to submit the changes to SVN: 　　The following starts to create a branch: 1, on the trunks right click on the TortoiseSVN menu

To facilitate management, it is best to maintain a central version library. A central version Library (called its origin) should include at least two branches, namely "master" and "Development Branch )". Make sure that all the code obtained by the Team members from the master

The branch restriction method is similar to the Backtracking Method, and is also an algorithm used to search for the problem solution on the spatial tree T of the problem. However, in general, the branch restriction method and the Backtracking Method have different targets. The solution objective of the backtracking method is to find all the solutions that meet the constraints in T, while the solution objec

Project background:The project was a flight reservation system developed by a Dutch customer in November 2011 using the ASP.

existing version; H20, H28,h26,i8 H28,h26,i8 is created from the H20 below. Requirements: Create a new branch from below H28 continue development. Ideas: All the code is placed in the H20 warehouse, first download the H20 full repository, that is, the. git folder content, which is essentially a zip file. Then remove a branch from the repository (such as H28), which is all the code that synchronizes to a

Whether you encounter this problem when using git:you're using Git for versioning, and one day you went on to work yesterday and you submitted n commits, and the result is that when you merge the remote branch, you don't notice the state of the branch you're submitting before you work .As a result, the results of your submission to the hotfix branch are all submi
