module MergeRequests
# OldestPerCommitFinder is used to retrieve the oldest merge requests for
# every given commit, grouped per commit SHA.
#
# This finder is useful when you need to efficiently retrieve the first/oldest
# merge requests for multiple commits, and you want to do so in batches;
# instead of running a query for every commit.
class OldestPerCommitFinder
def initialize(project)
@project = project
end
# Returns a Hash that maps a commit ID to the oldest merge request that
# introduced that commit.
