paleolimbot opened a new pull request, #41763: URL: https://github.com/apache/arrow/pull/41763
### Rationale for this change Neither Schema.fbs nor the Arrow C Data interface nor the columnar specification indicates that the ARROW:extension:metadata key must be present; however, the `ImportType()` implementation assumes that both `ARROW:extension:name` and `ARROW:extension:metadata` are both present and throws an exception if `ARROW:extension:metadata` is missing. This causes pyarrow to crash (see issue for reproducer). ### What changes are included in this PR? This PR checks that the extension metadata is present before attempting to delete it. ### Are these changes tested? Yes (test added). ### Are there any user-facing changes? No. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
