Create a “patch” between versions?

Question

It seems that the SVN "patch" functionality is not quite what I want. I really want to make the difference between the versions. Thus, I would select rev1 and rev 2 and in the end be a folder containing all the files that have been changed or added between these versions.

Can this be done with Tortoise SVN or plain svn?

Answer 1

This can be achieved in the SVN turtle itself. Right-click on the branch (folder) from which you want to create a patch → Show Log → Select All versions for which you need to create a patch → Right-click and select Compare revisions → This will show the modified files → Select all files → Click right-click and select Export Revision To → Specify any path on your computer → Files will be exported to the appropriate folder structure.

Alternatively, you can achieve this with scripts. To do this, refer to the following link:

Answer 2

At the command line, you can do this as follows.

All files in a folder

Create a patch in your home folder containing all the changes between versions 123 and 124 of all the changed files in the my_project folder:

 svn diff -r123:124 path/to/my_project > ~/my_project_changes_123_124.patch 

One specific file

Create a patch in your home folder containing all the changes between versions 123 and 124 from only one file, the name is "my_project.php":

 svn diff -r123:124 path/to/my_project/my_project.php > ~/my_project_changes_123_124.patch 

Answer 3

Um ... how about svn diff ? Just pass it the necessary changes.

In TortoiseSVN, if you highlight the changes you want in the "show log" dialog box, there is even a context menu item to display the changes as diff, which you can then save somewhere.
