Describe the bug
There appears to be a data corruption issue while reading an ORC file generated in fuzz-testing. Pyarrow is able to read the file correctly but not cudf.

Steps/Code to reproduce bug
'bug.orc' is made available internally to the cuio team as it is large for a github upload.

>>> import cudf
>>> import pyarrow as pa
>>> t = pa.orc.ORCFile(open('bug.orc', 'rb')).read()

Based on branch-22.10 I tested correctness of cudf.read_orc with struct types. The testing used the following patches:

Enable struct columns for the OrcReader:

cudf/python/cudf/cudf/_fuzz_testing/orc.py

Line 57 in 493d96b

dtypes_list = list( 

dtypes_list = list(
        cudf.utils.dtypes.ALL_TYPES
        - {"category"}
        # Following dtypes are not supported by orc
        # https://orc.apache.org/specification/ORCv0/
        - cudf.utils.dtypes.TIMEDELTA_TYPES
        - cudf.utils.dtypes.UNSIGNED_TYPES
        - cudf.utils.dtypes.DATETIME_TYPES
        | {"struct"}
    )

Enable struct children in the dataset generator:

cudf/python/cudf/cudf/testing/dataset_generator.py

Line 839 in 493d96b

dtypes_list = cudf.utils.dtypes.ALL_TYPES 

dtypes_list = list(
        cudf.utils.dtypes.ALL_TYPES
        - {"category"}
        # Following dtypes are not supported by orc
        # https://orc.apache.org/specification/ORCv0/
        - cudf.utils.dtypes.TIMEDELTA_TYPES
        - cudf.utils.dtypes.UNSIGNED_TYPES
        - cudf.utils.dtypes.DATETIME_TYPES
        - {"datetime64[ns]"}
        | {"struct"}
    )

and the following test script:

import io, random
import cudf
from cudf._fuzz_testing.orc import OrcReader
from cudf._fuzz_testing.utils import compare_dataframe

r = OrcReader(
    max_rows=8,
    max_columns=8,
    max_string_length=8,
)

for x in range(50):
    random.seed(x)
    try:
        pdf, buf = r.generate_input()
        df = cudf.read_orc(
            io.BytesIO(buf),
        )
        compare_dataframe(df, pdf)
    except RecursionError as err:
        # this error is due to the python recursion limit of 1000
        # this is not a `read_orc` error
        print(f"Fuzz testing error in test case {x}: {err}")

For now I'm satisfied that there aren't significant issues with struct support in cuIO read_orc. If we find a minimum reproducer for a Orc reader failure, please open a new issue.

After more investigation, I believe there is something non-compliant or slightly off-spec with the original file. Re-writing the file with pyarrow==8.0.0 shows the data to be intact.

import cudf
import pandas as pd
import pyarrow as pa

pdf = pd.read_orc('bug.orc')
