   @u70b3 Please don't @ me. I won't be contributing to DataFusion anymore. Do 
whatever you want with it.

   FYI: I'm picking this up since the previous attempt #22250 was closed 
unmerged by its author on 2026-06-04. My PR follows the approach that was 
approved there (stop after the last reachable value, matching 
PostgreSQL/DuckDB) and also fixes #22193 in the same file. cc @xiedeyantu in 
case you had work in progress here.

[I] panic: generate_series table function overflows when integer step passes i64::MAX [datafusion]

2026-05-15 Thread via GitHub 


Dandandan opened a new issue, #22208:
URL: https://github.com/apache/datafusion/issues/22208

   ### Describe the bug
   
   The table-valued `generate_series(start, stop, step)` can panic when the 
integer iterator advances past `i64::MAX` while evaluating user SQL.
   
   ### To Reproduce
   
   ```sql
   SELECT * FROM generate_series(9223372036854775806, 9223372036854775807, 2);
   ```
   
   ### Actual behavior
   
   `datafusion-cli` panics:
   
   ```text
   thread 'main' panicked at 
datafusion/functions-table/src/generate_series.rs:101:9:
   attempt to add with overflow
   ```
   
   ### Expected behavior
   
   DataFusion should return a normal execution error or stop iteration without 
panicking.
   
   ### Notes
   
   This is distinct from the already-filed capacity-overflow issue for scalar 
`range`/`generate_series`; this panic is the table function's iterator doing 
unchecked `current + step`.
