ASF GitHub Bot updated ARROW-9037: ---------------------------------- Labels: pull-request-available (was: ) > [C++/C-ABI] unable to import array with null count == -1 (which could be > exported) > ---------------------------------------------------------------------------------- > > Key: ARROW-9037 > URL: https://issues.apache.org/jira/browse/ARROW-9037 > Project: Apache Arrow > Issue Type: Bug > Components: C++ > Affects Versions: 0.17.1 > Reporter: Zhuo Peng > Priority: Major > Labels: pull-request-available > Time Spent: 10m > Remaining Estimate: 0h > > If an Array is created with null_count == -1 but without any null (and thus > no null bitmap buffer), then ArrayData.null_count will remain -1 when > exporting if null_count is never computed. The exported C struct also has > null_count == -1 [1]. But when importing, if null_count != 0, an error [2] > will be raised. > [1] > https://github.com/apache/arrow/blob/5389008df0267ba8d57edb7d6bb6ec0bfa10ff9a/cpp/src/arrow/c/bridge.cc#L560 > [2] > https://github.com/apache/arrow/blob/5389008df0267ba8d57edb7d6bb6ec0bfa10ff9a/cpp/src/arrow/c/bridge.cc#L1404 > -- This message was sent by Atlassian Jira (v8.3.4#803005)
