Submitting a Change to Gerrit¶
Carefully review the following before submitting a change. These guidelines apply to developers that are new to open source, as well as to experienced open source developers.
This section contains guidelines for submitting code changes for review. For more information on how to submit a change using Gerrit, please see Gerrit.
Changes are submitted as Git commits. Each commit must contain:
- a short and descriptive subject line that is 72 characters or fewer, followed by a blank line.
- a change description with your logic or reasoning for the changes, followed by a blank line
- a Signed-off-by line, followed by a colon (Signed-off-by:)
- a Change-Id identifier line, followed by a colon (Change-Id:). Gerrit won’t accept patches without this identifier.
A commit with the above details is considered well-formed.
All changes and topics sent to Gerrit must be well-formed.
commit messages must include:
- what the change does,
- why you chose that approach, and
- how you know it works – for example, which tests you ran.
Commits must build cleanly when applied on top of each other, thus avoiding breaking bisectability. Each commit must address a single identifiable issue and must be logically self-contained.
For example: One commit fixes whitespace issues, another renames a function and a third one changes the code’s functionality. An example commit file is illustrated below in detail:
[FAB-XXXX] A short description of your change with no period at the end You can add more details here in several paragraphs, but please keep each line width less than 80 characters. A bug fix should include the issue number. Change-Id: IF7b6ac513b2eca5f2bab9728ebd8b7e504d3cebe1 Signed-off-by: Your Name <email@example.com>
Include the issue ID in the one line description of your commit message for readability. Gerrit will link issue IDs automatically to the corresponding entry in Jira.
Each commit must also contain the following line at the bottom of the commit message:
Signed-off-by: Your Name <firstname.lastname@example.org>
The name in the Signed-off-by line and your email must match the change
authorship information. Make sure your :file:
.git/config is set up
correctly. Always submit the full set of changes via Gerrit.
When a change is included in the set to enable other changes, but it will not be part of the final set, please let the reviewers know this.
