This article will explain in detail about the role of svn, the editor thinks it is very practical, so share it with you for reference. I hope you can get something after reading this article.

Svn is an open source version control system, through the efficient management of branch management system, in short, it is used for multiple people to jointly develop the same project, to achieve shared resources, to achieve the final centralized management.

This article operating environment: Windows7 system, Subversion version 1.9.7, Dell G3 computer.

Apache Subversion (SVN,svn for short), an open source code version control system, compared with RCS, CVS, it uses a branch management system, its design goal is to replace CVS. Many version control services on the Internet have been transferred from CVS to Subversion.

Characteristics

A unified version number. CVS arranges the version number of each file sequentially, and the version number of each file is different at a certain time. Under Subversion, any submission will add the same new version number to all files, even those that are not involved. Therefore, the version number of each file is the same at any time. Files with the same version number constitute a version of the software.

Atomic submission. Whether single or multiple files are submitted at a time, they are submitted as a whole. Accidents such as transmission interruptions do not cause database incompleteness and data corruption.

Renaming, copying, deleting files, and other actions are stored in the version history.

For binary files, a space-saving storage method is used (to put it simply, it is only different from the previous version).

Directories also have version history. The entire directory tree can be moved or copied, it is easy to operate, and all version records can be retained.

The overhead of the branch is very small.

Optimized database access allows some operations to be done without having to access the database. This reduces a lot of unnecessary network traffic with the database host.

Support metadata (Metadata) management. Each directory or file can define Property, which are hidden key-value pairs, and users can customize the content of the property, and the property is under version control as well as the content of the file.

Both FSFS and Berkeley DB database formats are supported.
