SVN(Subversion) is a free, open-source project source code versioning tool. Currently, the vast majority of open source and Enterprise code management uses SVN as the code version management software.

Subversion stores files in the central repository, which is much like an ordinary file server. The difference is that it records the changes to each file and directory, so that you can restore the data to the previous version and see the details of the changes in the data when the rollback is needed.

SVN server configuration: Install SVN server

One, svn common commands

1. Checkout files to a local directory
SVN checkout Path (path is a directory on the server)
Shorthand: SVN Co

2. Add a new file to the repository
SVN Add File

3. Submit the changed files to the repository
SVN commit-m "LogMessage" [-n] [--no-unlock] PATH (use –no-unlock switch if hold lock is selected)
Shorthand: svn ci

4. Locking/unlock
SVN lock-m "Lockmessage" [--force] PATH
SVN unlock PATH

5. Update to a version
SVN update-r m path
Shorthand: SVN up

6. View file or directory status
1) SVN status path (status of files and subdirectories under directory, normal status not shown)
2) SVN status-v path (show file and subdirectory status)
Shorthand: SVN St

7. Delete Files
SVN delete path-m "Delete test Fle"
Shorthand: SVN (del, remove, RM)

8. View Logs
SVN log path

9. View File Details
SVN info Path

10. Compare Differences
SVN diff path (compares the modified file to the base version)
SVN diff-r m:n Path (difference between version m and version N)
Shorthand: SVN di

11. Merge the differences between the two versions into the current file
SVN merge-r m:n Path

12. SVN Help
SVN help
SVN help CI

second, svn not commonly used commands
13. List of files and directories under the repository
SVN list path displays all files and directories belonging to the repository in the path directory shorthand: SVN ls

14. Create a new directory under version control
SVN mkdir: Create a new directory under the included version control.
1. mkdir PATH ...
Each directory specified in the working copy PATH will be created on the local side and added to the new schedule for the next commit.
2. mkdir URL ... Create a version-controlled directory.
Each directory specified in the URL is created by submitting it to the repository immediately. In both cases, all intermediate directories must exist beforehand.

15. Restore Local Modifications
SVN revert: Restores the original unchanged working copy file (restores most of the local modifications).
Usage: revert PATH ... Note: The notebook command will not access the network and will release the conflicting condition. But it does not restore the deleted directory

16. Code base URL Change
SVN switch (SW): Updates the working copy to a different URL.
1. Switch URL [PATH]
Updating your working copy, mapped to a new URL, behaves like "SVN update" and merges the file on the server with the local file. This is the method that corresponds a working copy to a branch or tag in the same warehouse.
2. Switch--relocate from to [PATH ...]
Overwrites the URL metadata of the working copy to reflect the changes on the simple URL. When the repository's root URL changes (such as scheme name or hostname change), but the working copy is still mapped to the same directory as the same repository, use this command to update the corresponding relationship between the working copy and the warehouse.

17. Conflict resolution
SVN resolved: Removes the "conflicting" status of the working Copy's directory or file.
Usage: Resolved PATH ... Note: The book command does not resolve the conflict by syntax or remove the conflict token; it simply removes the conflicting file and then allows PATH to commit again.

18. Output the contents of the specified file or URL.
SVN cat Target [@ VERSION] ... If a version is specified, the lookup starts from the specified version. SVN cat-r PREV filename > filename (PREV is the previous version, you can also write a specific version number so that the output can be submitted)

Third, svn other commands

Although not as common as the commands discussed earlier in this chapter, you sometimes need these commands.

SVN cleanup
When subversion modifies your working copy (or any information in. svn), it tries to be as secure as possible. Before changing a working copy, Subversion writes its intent to a log file. It then executes the commands in the log file to apply the required modifications. Finally, subversion deletes the log file. Architecturally, this is similar to a log file system (journaled filesystem). If a subversion operation is interrupted (for example, the process is killed, or the machine is lost), the log file is still on the hard disk. Re-executing the log file, subversion can complete the previous operation so that your working copy can return to a reliable state.

Here's what SVN cleanup does: It searches your working copy and executes all the remaining logs, removing the lock during this process. If subversion has told you that part of your working copy is "locked", then you should execute this command. In addition, SVN status displays L before locked items.

$ SVN status
L Somedir

$ svn cleanup
$ SVN status

SVN import
Using SVN import is a quick way to copy the non-versioned file tree to the repository, and it needs to create a temporary directory.

$ svnadmin Create/usr/local/svn/newrepos
$ svn Import mytree File:///usr/local/svn/newrepos/some/project
Adding mytree/bar.c
Adding Mytree/subdir
Adding mytree/subdir/quux.h

Committed Revision 1.

The above example copies the contents of the Mytree directory under the Some/project directory to the repository.

$ SVN List File:///usr/local/svn/newrepos/some/project

Note After the import is complete, the original tree is not converted to a working copy. To get started, you still need SVN checkout a new working copy of the tree.

View SVN version


Ubuntu Install SVN 1.7, 1.8

Currently in Ubuntu 12.04, the SVN version is 1.6, this version will create a new. SVN directory in each subdirectory to save the version file, very uncomfortable. Find a third-party compiled Ubuntu Source:

1) Open Source.list Source:

sudo vi/etc/apt/sources.list

2) Add source

Deb Http:// Precise Main

Deb-src Http:// Precise Main

3) Execute the installation command

sudo apt-get install subversion

SVN rollback operation (undo modification)

  Sometimes we want to discard the changes we've made to our code.  
in two cases:  
One, the change does not have check in. In this case, we can use SVN revert to get rid of the changes.  
   tip: CVS users are accustomed to deleting only locally modified files and then performing an update to restore the files. This can be done in SVN, but the best practice is to perform SVN revert, which is more secure and faster. Because update needs to connect to the server and you are not ready to accept the new changes, SVN revert will not connect to the server and will not get new changes from the server.  

Second, the change has been check in.  
   In this case, there are several ways to undo the modification. In general, we recommend using SVN Merge to achieve this goal.  
   Typical operation process is as follows:  
  1, make sure we get the latest code:  
     SVN update 
     assumed to be version 28.  
  2, and then find out the exact version to remove:
