evolve: remove not required calls to phases.retractboundary()
To make sure phases are preserved during evolve, we started using the
phases.new-commit config option. Now we don't need to call
phases.retractboundary(). Let's remove the redundant code.
import hghave
@hghave.check("docgraph-ext", "Extension to generate graph from repository")
def docgraph():
try:
import hgext.docgraph
hgext.docgraph.cmdtable # trigger import
except ImportError:
try:
import hgext3rd.docgraph
hgext3rd.docgraph.cmdtable # trigger import
except ImportError:
return False
return True
