Create “patch” between revisions?

Question

It seems SVN's "patch" functionality is not exactly what I want. What I really want is to create a diff of files between revisions. So, I'd choose rev1 and rev 2 and end up with a folder containing all files that were changed or added between those revisions.

Can this be done with Tortoise SVN or plain-old svn?

Answer 1

From the command line you could do this as follows.

All files in a folder

Create a patch in your Home folder that contains all the changes between revision 123 and 124 from all the changed files in the folder "my_project":

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

One particular file

Create a patch in your Home folder that contains all the changes between revision 123 and 124 from only one file, name "my_project.php":

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

Answer 2

Um...how about svn diff? Just pass it the desired revisions.

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

This can be achieved in tortoise SVN itself. Right click on the branch(folder) from where you want to create the patch >> Show Log >> Select All the revisions for which you need to create the patch >> Right Click and select Compare revisions >> This will show the changed files >> Select all the files >> Right click and select Export Revision To >> Give any path in your machine >> The files will get exported in the respective folder structure.

Alternately you can achieve this via scripting. Refer the following link for that:
