1. Specify the branch against which the patch should be created (-b)
2. Specify the corresponding JIRA (-j)
3. Specify an optional summary (-s) and description (-d) for the reviewboard

Example:

 python kafka-patch-review.py -b origin/trunk -j KAFKA-42 -s "test summary" -d "test description"

4. Update patch

1. Specify the branch against which the patch should be created (-b)
2. Specify the corresponding JIRA (--jira)
3. Specify the rb to be updated (-r)
4. Specify an optional summary (-s) and description (-d) for the reviewboard, if you want to update it

FAQ

When I run the script, it throws the following error and exits

...

nnarkhed$python kafka-patch-review.py -b trunk -j KAFKA-42
There don't seem to be any diffs

There are 2 reasons that can cause this -

• The code is not checked into your local branch
• The -b branch is not pointing to the remote branch. In the example above, "trunk" is specified as the branch, which is the local branch. The correct value for the -b (--branch) option is the remote branch. "git branch -r" gives the list of the remote branch names.

When I run the script, it throws the following error and exits

Error uploading diff

Your review request still exists, but the diff is not attached.

One of the most common root causes of this error are that the git remote branches are not up-to-date. Since the script already does that, it is probably due to some other problem. You can run the script with the --debug option that will make post-review run in the debug mode and list the root cause of the issue.
