# Finder for obtaining the unique environment names of a project or group.
#
# This finder exists so that the merge requests "environments" filter can be
# populated with a unique list of environment names. If we retrieve _just_ the
# environments, duplicates may be present (e.g. multiple projects in a group
# having a "staging" environment).
#
# In addition, this finder only produces unfoldered environments. We do this
# because when searching for environments we want to exclude review app
# environments.

# We assume reporter access is needed for the :read_environment permission
# here. This expection is also present in
# IssuableFinder::Params#min_access_level, which is used for filtering out
# merge requests that don't have the right permissions.
#
# We use this approach so we don't need to load every project into memory
# just to verify if we can see their environments. Doing so would not be
# efficient, and possibly mess up pagination if certain projects are not
# meant to be visible.
