The SPM CI failure is a result of #6777. I'll make a fix for that and then restart this. |
The root of the issue is that when serializing a singular filter, it is being treated as a unary filter before it is definitively established whether it is a unary filter or a field filter. The leak is caused by always serializing the unary filter's field path field for equality and non-equality filters -- if the filter's value turns out not to be NaN or null, the serialization code switches the filter's type to a field filter without clearing the partially-initialized unary filter. `pb_release` would not free the `unary_filter.field.field_path` member variable because it would consider the object not to be a unary filter. Also a small refactoring to make the function easier to digest.

Merging now. I'll update the tags and rebuild the zip in the morning. |
