Introduction to SVN

SVN is a version management system, formerly known as CVS, is the cornerstone of open source software. Even in the case of full communication, there must be confusion when multiple people maintain the same source code, and the version management system is designed to solve these problems.

Some concepts in SVN:

A. repository (source code base)

A place where the source code is stored uniformly

B. Checkout (extraction)

When you don't have the source code, you need a copy from repository checkout

C. Commit (submit)

When you have modified the code, you need to Commit to repository

D. Update (update)

When you have Checkout a copy of the source code, Update you can synchronize with the source code on Repository, and the code on hand will have the latest changes.

Introduction to TortoiseSVN

TortoiseSVN is a free open source client for the Subversion version control system that can manage files and directories over time. Files are saved in a central version library, which is very much like an ordinary file server, except that it can remember every change to the file and directory. You can restore the file to the previous version, and you can check the history to know what changes were made to the data and who made the changes. This is why many people regard Subversion and version control systems as "time machines".

Client use

The use of Windows client TortoiseSVN

1, installation of TortoiseSVN client

The test selected TortoiseSVN 1.6.5 client to pay the Chinese language package.

2. Update the files from the client to the server (user1 operation)

Create a new empty directory and right-click Checkout (extract)

Svn://192.168.103.26 / winne

Just enter the authorized user account in the passwd file

Add some file tests to the directory. Then right-click TortoiseSVN- > ADD in the empty space to add the list to the server.

You can see the file you just submitted in the version library browser.

3, the client pulls and reads data on the server (user2 operation)

User2 create an empty directory user2 on the machine, right-click Checkout (extract)

Fill in the address: svn://192.168.103.26/winne output to G:\ user2 to confirm

Add a new.txt file, and then Commit (submit) after the prompt permission error, user2 does not have write permission, change to the identity of user1 can be submitted successfully.

The use of Linux client

The client operation process is generally as follows:

User A: checkout (extract)-> add (add new file)-> commit (submit)

User B: SVN log (View updates)-> update (newer version)

Installation of 1D SVN

Yun-y install subversion

2Common commands of Linux svn

() is the abbreviation of the order.

Checkout (co) extraction

Commit (ci) submission

Update (up) update

List (ls) list

3. Checkout (co) extracts files from the svn server

(user1) Operation flow

[root@TEST ~] # svn co svn://192.168.103.26/winne

Authentication realm: My First Repository

Password for 'root':

Authentication realm: My First Repository

Username: user1 / enter user name

Password for 'user1': / enter password

A winne/Cosmic Ride-BeFour.lrc

A winne/20070716171657126.pdf

A winne/svnbook.pdf

Revision 1. / checkout (co) was extracted successfully. You can see that Checked out version is 1.

Note: you can use access with a user name and password:

Svn co-username user1-password user1 svn://192.168.103.26/winne

[root@TEST ~] # ll

4Jing user1 modify the file and submit it

[root@TEST winne] # vi testsvn.txt

[root@TEST winne] # svn add testsvn.txt / add testsvn.txt to the library

A testsvn.txt

[root@TEST winne] # svn commit-m "test" testsvn.txt / annotated as test

Adding testsvn.txt

Transmitting file data.

Committed revision 2. / version 2 is updated to 2

5Jing user2 back to window client updated version
