Hongze Zhang closed ARROW-11143. -------------------------------- Resolution: Won't Fix I'm closing this. Thanks Antoine and Wes. > [C++] Support status return for method MemoryPool::Free > ------------------------------------------------------- > > Key: ARROW-11143 > URL: https://issues.apache.org/jira/browse/ARROW-11143 > Project: Apache Arrow > Issue Type: Improvement > Components: C++ > Reporter: Hongze Zhang > Priority: Major > > Currently MemoryPool::Free has void return: > https://github.com/apache/arrow/blob/e05f032c1e5d590ac56372d13ec637bd28b47a96/cpp/src/arrow/memory_pool.h#L88. > This is not enough for some complicated scenarios like in ARROW-7808, we > bring some possible JNI calls in the method within class > ReservationListenableMemoryPool: > https://github.com/apache/arrow/pull/7030/files#diff-ad18b6c937b5960c70ef6825654a98de6ee33ae72127a4af4895afe944966144R582-R604. > We can discuss more on this before actually solving this issue in case we > think of `Free` is always a error-free behavior comparing to `Allocate`. > Anyway if the logic of cod e grows there will always be complicated codes > that can throw errors to be brought. Anyway we can expect some more comments > to this topic from dev. -- This message was sent by Atlassian Jira (v8.3.4#803005)
