Eason0729 opened a new pull request, #1468:
URL: https://github.com/apache/datafusion-sqlparser-rs/pull/1468
## Changed
under `#[cfg(feature="std")]`, `stacker::maybe_grow` was called in
`RecursionCounter::try_decrease` to prevent stack overflow
I also tested on Windows(stack size 1MB), it seems fine.
### reproducible code from original issue
```rust
use datafusion::prelude::{ParquetReadOptions, SessionContext};
#[tokio::main(flavor = "current_thread")]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let ctx = SessionContext::new();
ctx.register_parquet(
"parquet_table",
"batches.parquet",
ParquetReadOptions::default(),
)
.await?;
let sql_query = "
SELECT seq
FROM (
SELECT seq,
LEAD(seq) OVER (ORDER BY seq) AS next_seq
FROM parquet_table
) AS subquery
WHERE next_seq - seq > 1";
let df = ctx.sql(sql_query).await?;
df.show().await?;
Ok(())
}
```
## Missing
- [ ] Return error when growing stack fail:
growing stack on unsupported target seems to be no-op on stacker side, so I
am unable to detect it.
- [ ] Test: which part should be tested?
- [ ] Observe performance impact
