We want to get an idea of the amount of work needed to display activity related to PersonalSnippets in the user's profile (along with ProjectSnippets activity). As per [Fran's suggestion](https://gitlab.com/gitlab-org/gitlab/issues/19998#note_287499006), we could achieve that by: - Removing [this return in `Notes::PostProcessService`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/services/notes/post_process_service.rb#L16) - Including snippets with `project_id: nil` in [this query from `Gitlab::ContributionsCalendar`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/contributions_calendar.rb#L51). Possibly, trying that in [`Gitlab::ContributionsCalendar#events_by_date`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/contributions_calendar.rb#L49-52) and [`UserRecentEventsFinder#execute`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/finders/user_recent_events_finder.rb#L28-35) as well - Testing related views like [calendar_activities](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/views/users/calendar_activities.html.haml) to help identify other changes ### Context - Currently, only comments on `ProjectSnippets` are shown as activity items in the user's profile. - The snippets related activity is scoped to the projects the user contributes to. - Comments on PersonalSnippets create events in the db but are not displayed as they don't belong to any project. - Other types of events would need to be created as currently only comments are tracked.
