[I] panic: interval analysis Interval::cardinality adds past u64::MAX for BETWEEN spanning full i64 range [datafusion]

2026-05-15 Thread via GitHub 


Dandandan opened a new issue, #22232:
URL: https://github.com/apache/datafusion/issues/22232

   ### Describe the bug
   
   Optimizer interval analysis panics when a `BETWEEN` predicate spans the
   full `i64` range. `Interval::cardinality` finishes with
   `.map(|result| result + 1)` and the `+ 1` overflows when the inner range
   already equals `u64::MAX`.
   
   ### To Reproduce
   
   ```sql
   SELECT * FROM (VALUES (1)) AS t(x)
   WHERE x BETWEEN -9223372036854775808 AND 9223372036854775807;
   ```
   
   ### Actual behavior
   
   ```text
   thread 'main' panicked at 
datafusion/expr-common/src/interval_arithmetic.rs:968:23:
   attempt to add with overflow
   ```
   
   Call path: `Interval::cardinality::{{closure}}` → `cardinality_ratio`
   → `calculate_selectivity` → `shrink_boundaries` → `analyze`.
   
   ### Expected behavior
   
   Cardinality should saturate (e.g. `u64::MAX`) or return `None`, not panic.
   
   ### Notes
   
   Source: 
https://github.com/apache/datafusion/blob/53.1.0/datafusion/expr-common/src/interval_arithmetic.rs#L968
   
   Related but distinct from closed #16736 (float subtract overflow in the
   same module).
   
   Found via LLM-guided fuzz testing on DataFusion 53.1.0.
