Assertion failed when importing CSV with string list

[rfdavid]

To benchmark #1327 for string list, I created the following node table and imported a CSV with randomly generated values:

CREATE NODE TABLE Preference(name STRING, pref STRING[], PRIMARY KEY (name));

When trying to match the list, I'm getting an assertion failed:

➜  shell git:(master) ./kuzu_shell -i db
Opened the database at path: db
Enter ":help" for usage hints.
kuzu> match (p:Preference) return p.pref;
Assertion failed: (srcEndIdx < src.size), function copyListRecursiveIfNested, file in_mem_overflow_buffer_utils.cpp, line 31.

Hi Rui,

We will look into this. Meanwhile I think benchmarking PR #1327 meaning you need a Rel table with a STRING property and test the scan performance of reading that property.

E.g.

MATCH (a:person)-[e:knows]->(b:person) RETURN e.strProp

Hi Rui,

I tried to load the csv you provided and query the Preference table. However, i can't reproduce the error you reported. Could you please provide me your building environment so i can better dig into this issue?

Thanks,

Hi Ziyi,

I built both on debug and release, and basically ran the following

DROP table Preference; 
CREATE NODE TABLE Preference(name STRING, pref STRING[],  PRIMARY KEY (name)) ; 
COPY Preference FROM "pref.csv"; 
match (p:Preference) return p.pref;

In release (both compiling and downloading from the website), the query runs normally and doesn't produce any seg fault. I'm running on Apple Silicon. Is there anything more specific that I can provide?

Hi Rui,

Thanks for you feedback, I could reproduce the bug under Apple Silicon and DEBUG mode. We will fix this bug as soon as possible.

Hi Rui,

This bug is caused by copying an empty list and i have fixed it in PR #1358. Can you try to load your csv again and confirm whether the bug has been solved.

I compiled it again and everything is working now 👍
