annotate pkg/controllers/system.go @ 5591:0011f50cf216 surveysperbottleneckid

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Removed no longer used alternative api for surveys/ endpoint. As bottlenecks in the summary for SR imports are now identified by their id and no longer by the (not guarantied to be unique!) name, there is no longer the need to request survey data by the name+date tuple (which isn't reliable anyway). So the workaround was now reversed.
