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.
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 branch:master
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 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 project.config
file.
To edit the project level notify settings, ensure the project owner has Push permission already granted for the refs/meta/config
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 team-address@example.com git config -f project.config --add notify.team.email paranoid-manager@example.com
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 = team-address@example.com email = paranoid-manager@example.com
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 team-address@example.com of changes" git push ssh://localhost:29418/project HEAD:refs/meta/config
notify.<name>.email
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 NAME
syntax. If this format is used the group’s UUID must also appear in the corresponding groups
file. Gerrit will expand the group membership and BCC all current users.
notify.<name>.type
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.
notify.<name>.header
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.
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.
notify.<name>.filter
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)-.*\"
.
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 = team-address@example.com 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 <your.email@example.com>"
Gerrit-MessageType
The message type footer states the type of the message and will take one of the following values.
abandon
comment
deleteReviewer
deleteVote
merged
newchange
newpatchset
restore
revert
setassignee
Gerrit-Change-Id
The change ID footer states the ID of the change, such as I3443af49fcdc16ca941ee7cf2b5e33c1106f3b1d
.
Gerrit-Change-Number
The change number footer states the numeric ID of the change, for example 92191
.
Gerrit-PatchSet
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 7
.
Gerrit-Owner
The owner footer states the name and email address of the change’s owner. For example, Owner Name <owner@example.com>
.
Gerrit-Reviewer
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 <one@example.com> Gerrit-Reviewer: Reviewer Two <two@example.com>
Gerrit-CC: User One <one@example.com> Gerrit-CC: User Two <two@example.com>
Gerrit-Project
The project footer states the project to which the change belongs.
Gerrit-Branch
The branch footer states the abbreviated name of the branch that the change targets.
Gerrit-Comment-Date
In comment emails, the comment date footer states the date that the comment was posted.
Gerrit-HasComments
In comment emails, the has-comments footer states whether inline comments had been posted in that notification using “Yes” or “No”, for example Gerrit-HasComments: Yes
.
Gerrit-HasLabels
In comment emails, the has-labels footer states whether label votes had been posted in that notification using “Yes” or “No”, for example Gerrit-HasLabels: No
.
