> [Python] [Gandiva] Check parameters are not None
> ------------------------------------------------
>
> Key: ARROW-11341
> URL: https://issues.apache.org/jira/browse/ARROW-11341
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++ - Gandiva, Python
> Reporter: Will Jones
> Assignee: Will Jones
> Priority: Minor
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h

> Most of the functions in Gandiva's Python Expression builder interface current accept None in their arguments, but will segfault once they are used.
> Example:
> {code:python}
> import pyarrow
> import pyarrow.gandiva as gandiva
> builder = gandiva.TreeExprBuilder()
> field = pyarrow.field('whatever', type=pyarrow.date64())
> date_col = builder.make_field(field)
> func = builder.make_function('less_than_or_equal_to', [date_col, None], pyarrow.bool_())
> condition = builder.make_condition(func)
> # Will segfault on this line:
> gandiva.make_filter(pyarrow.schema([field]), condition)
> {code}
> I think this is just a matter of adding {{not None}} to the appropriate function arguments.
