Working with Drupal Patch Files
3 years ago

A patch is a small file which shows what was changed in a repository. It shows the new changes in an existing file, details of the new files in the current directory, file deletion details etc. A patch file can be pushed to the git repository so that it is useful in the future for updating the changes in the corresponding file.

For creating a patch file in your current git repository, make changes in your files. Now open the terminal.

For unstaged changes, type the following command,

git diff > new-changes.patch

For staged changes, you have to use git diff --cached. That is,

git diff --cached > new-changes.patch

To apply the patch, use:

git apply -v new-changes.patch

Note that, if the changes is already there when applying your patch, error message will be shown.

In, you can contribute patches to the existing core or contributed modules. For this,

  • First clone the latest version of Drupal (if it is a contributed module clone the latest code from its version control)
  • You have to create the issue with necessary issue summary in based on the fix
  • After making the changes, create a patch file based on the issue number as,
    git diff > [issue-description]-[issue-number]-[comment-number].patch
  • Update the issue with necessary comment and patch file
  • Make it's status as 'Needs Review'
  • If you want to test the patch file, add it to the queue by clicking the 'Add test' link shown below of the updated patch file

We can create and add inter diff for adding new modification for an existing patch file in an issue in, if the changes are not in the latest version of the module. For this,

  • Apply the existing patch to the latest version of module
  • Add your changes to the module
  • Create a new patch from git diff using git diff > [issue-description]-[issue-number]-[comment-number].patch
  • Create an inter diff from the old and new patches as:
    interdiff old-file.patch new-file.patch > interdiff-[issue_id]-[old_comment_number]-[new_comment_number].txt
  • Upload the newly created patch and the inter diff to the created issue in

An interdiff file tells you what new changes are there with the existing patch and newly created patch. It provides the information of the changes in patch files. So we can make the file as test free using 'do not test' option in the issues itself. So for interdiff to be ignored by the testbot, we can name the interdiff file as:


Hope this information helps in your patch creation.

We have added a few new modules to our site recently. Drupal Technical StumbleThis Sean (not verified) access_time 21 Sep 2021 - 18:10 Hi there, I uploaded the files, enabled the modules to use SU, and now I see the link, but there is no icon... How can I fix this? Thanks, Sean webmaster access_time 21 Sep 2021 - 18:10 In reply to Icon doesn't show by Sean (not verified) What do you see when you view the source? Search for stumblethis_button and you should be able to see the code for the image and the URL. Then you should be able to troubleshoot from there.

Most webmasters do not realize this, but a lot of the content on lot of websites can be accessed from multiple URLs. A simple example would be where and leads to the same page. This is a fatal mistake in Search Engine Optimization and search engines penalize you for duplicate content. The correct configuration would be where the above two urls will lead you to the same page but will redirect you to with a 301 (Moved permanently) status which will not result in search engines penalizing the page. It is very easy to configure 301 redirects using Apache .htaccess file and the process is the same for a Drupal installation also.

I'm on Apache 2.0 and using the following lines in my httpd.conf file: RewriteEngine on RewriteCond %{HTTP_HOST} ^xxxxxxxxxx\.com$ [NC] RewriteRule ^(.*)$$1 [L,R=301] When I go to, I get (as expected). However, when I go to (it's a Drupal site), I get a 404 thrown and the URL changes to Same thing with Any suggestions? I want to run without Drupal's .htaccess file (instead incorporating these calls into my httpd.conf file). webmaster access_time 21 Sep 2021 - 18:10 In reply to Rewrite including filesystem path by Anonymous (not verified) I think the problem is with the base path which results in the redirection to /var/www/ part. The best approach I would think is to start with drupal htaccess and then strip out parts and move to httpd SNVC (not verified) access_time 21 Sep 2021 - 18:10 This is definitely a good guide.
