More tests of ColumnHelper, 2 of which fail
I attach a patch adding some more tests of ColumnHelper, 2 of which fail:
* testAddCleanColIntoColsExactOverlap
* Adds CTCol(min=1, max=1, hidden=true)
* Adds CTCol(min=1, max=1, bestFit=true)
* Expected: CTCol(min=1, max=1, hidden=true, bestFit=true)
* Actual: CTCol(min=1, max=1, hidden=true)
* testAddCleanColIntoColsNewOverlapsOverhangingLeftNotRightExactRight:
* Adds CTCol(min=2 max=3 hidden=true)
* Adds CTCol(min=1 max=3 bestFit=true)
* Note that a sort happens, meaning 1-3 is encountered first in the combine
operation.
* Expected: (min=1, max=1, bestFit=true), (min=2, max=3, bestFit=true,
hidden=true)
* Actual: (min=1, max=1, bestFit=true), (min=2, max=3, bestFit=true)
We have our own different implementation of a fast column merger which passes
these; it pre-dates trunk's current implementation introduced in r1561435 under
bug 54283. We can look at contributing our replacement if that's easier than
fixing the current implementation.
