Gerrit can automatically notify users by email when new changes are uploaded for review, after comments have been posted on a change, or after the change has been submitted to a branch.
Those are the available recipient types:
to: The standard To field is used; addresses are visible to all.
cc: The standard CC field is used; addresses are visible to all.
bcc: SMTP RCPT TO is used to hide the address.
User Level Settings
Individual users can configure email subscriptions by editing watched projects through Settings > Watched Projects with the web UI.
Specific projects may be watched, or the special project
All-Projects can be watched to watch all projects that
are visible to the user.
Change search expressions can be used to filter
change notifications to specific subsets, for example
to only see changes proposed for the master branch. If a filter would
match at the
All-Projects level as well as a specific project, the
more specific project’s notification settings are used.
Notification mails for new changes and new patch sets are not sent to the change owner.
Notification mails for comments added on changes are not sent to the user who added the comment unless the user has enabled the 'Every comment' option in the user preferences.
Project Level Settings
Project owners and site administrators can configure project level
notifications, enabling Gerrit Code Review to automatically send
emails to team mailing lists, or groups of users. Project settings
are stored inside of the
refs/meta/config branch of each Git
repository, and are placed inside of the
To edit the project level notify settings, ensure the project owner
has Push permission already granted for the
branch. Consult access controls for
details on how access permissions work.
Initialize a temporary Git repository to edit the configuration:
mkdir cfg_dir cd cfg_dir git init
Download the existing configuration from Gerrit:
git fetch ssh://localhost:29418/project refs/meta/config git checkout FETCH_HEAD
Enable notifications to an email address by adding to
project.config, this can be done using the
git config command:
git config -f project.config --add notify.team.email email@example.com git config -f project.config --add notify.team.email firstname.lastname@example.org
Examining the project.config file with any text editor should show a new notify section describing the email addresses to deliver to:
[notify "team"] email = email@example.com email = firstname.lastname@example.org
Each notify section within a single project.config file must have a unique name. The section name itself does not matter and may later appear in the web UI. Naming a section after the email address or group it delivers to is typical. Multiple sections can be specified if different filters are needed.
Commit the configuration change, and push it back:
git commit -a -m "Notify email@example.com of changes" git push ssh://localhost:29418/project HEAD:refs/meta/config
List of email addresses to send matching notifications to. Each email address should be placed on its own line.
Internal groups within Gerrit Code Review can also be named using
group NAMEsyntax. If this format is used the group’s UUID must also appear in the corresponding
groupsfile. Gerrit will expand the group membership and BCC all current users.
Types of notifications to send. If not specified, all notifications are sent.
new_changes: Only newly created changes.
new_patchsets: Only newly created patch sets.
all_comments: Only comments on existing changes.
submitted_changes: Only changes that have been submitted.
abandoned_changes: Only changes that have been abandoned.
all: All notifications.
Like email, this variable may be a list of options.
Email header used to list the destination. If not set BCC is used. Only one value may be specified. To use different headers for each address list them in different notify blocks.
The possible options are the recipient types.
Change search expression to match changes that should be sent to the emails named in this section. Within a Git-style configuration file double quotes around complex operator values may need to be escaped, e.g.
filter = branch:\"^(maint|stable)-.*\". Single quotes are illegal and must be omitted.
When sending email to a bare email address in a notify block, Gerrit
Code Review ignores read access controls and assumes the administrator
has set the filtering options correctly. Project owners can implement
security filtering by adding the
visibleto:groupname predicate to
the filter expression, for example:
[notify "Developers"] email = firstname.lastname@example.org filter = visibleto:Developers
When sending email to an internal group, the internal group’s read
access is automatically checked by Gerrit and therefore does not
need to use the
visibleto: operator in the filter.
Notification emails related to changes include metadata about the change to support writing mail filters. This metadata is included in the form of footers in the message content. For HTML emails, these footers are hidden, but they can be examined by viewing the HTML source of messages.
In this way users may apply filters and rules to their incoming Gerrit notifications using the values of these footers. For example a Gmail filter to find emails regarding reviews that you are a reviewer of might take the following form.
"Gerrit-Reviewer: Your Name <email@example.com>"
The message type footer states the type of the message and will take one of the following values.
The change ID footer states the ID of the change, such as
The change number footer states the numeric ID of the change, for example
The patch set footer states the number of the patch set that the email relates to. For example, a notification email for a vote being set on the seventh patch set will take a value of
The owner footer states the name and email address of the change’s owner. For example,
Owner Name <firstname.lastname@example.org>.
The reviewer footers list the names and email addresses of the change’s reviewrs. One footer is included for each reviewer. For example, if a change has two reviewers, the footers might include:
Gerrit-Reviewer: Reviewer One <email@example.com> Gerrit-Reviewer: Reviewer Two <firstname.lastname@example.org>
Gerrit-CC: User One <email@example.com> Gerrit-CC: User Two <firstname.lastname@example.org>
The project footer states the project to which the change belongs.
The branch footer states the abbreviated name of the branch that the change targets.
In comment emails, the comment date footer states the date that the comment was posted.
In comment emails, the has-comments footer states whether inline comments had been posted in that notification using "Yes" or "No", for example
In comment emails, the has-labels footer states whether label votes had been posted in that notification using "Yes" or "No", for example
In comment emails, a comment-in-reply-to footer is present for each account who has a comment that is replied-to in that set of comments. For example, to apply a filter to Gerrit messages in which your own diff comments are responded to, you might search for the following:
Gerrit-Comment-In-Reply-To: User Name <email@example.com>
