~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2009/05/20 - tsheyar: compiler/Tests/usageH.stable.out,1.57
-- Renamed algebra/intro_rec_border.c into algebra/intro_borders.c.
-- Renamed include/intro_rec_border.h into include/intro_borders.h.
-- Extended the physical algebra with a dependent cross product operator
that only evaluates its right side if the left side produces at least
one row.
This change implicitely implements a control structure for some conditionals.
E.g., the following query conditionally evaluates the independent
expressions ('doc("xmark-sf0.001.xml")//*' and 'doc("xmark-sf100.xml")//*'):
if (1 = (1,2,3))
then doc("xmark-sf0.1.xml")//*
else doc("xmark-sf100.xml")//*
With the dependent cross product operator in place this leads to the
evaluation
of the (previously independent) then-branch and the avoidance of the
evaluation
of the (expensive) else-branch.
-- Adjusted stable output.
