There was a problem hiding this comment.
I verified that this test covers the bugfix by reverting the code changes and running the tests:
called `Result::unwrap()` on an `Err` value: InvalidArgumentError("dictionary id 0 not found in schema")
thread 'reader::tests::test_roundtrip_nested_dict_no_preserve_dict_id' panicked at arrow-ipc/src/reader.rs:1735:79:
called `Result::unwrap()` on an `Err` value: InvalidArgumentError("dictionary id 0 not found in schema")

# Which issue does this PR close? Does not yet close, but contributes towards: - #6356 - #5981 - #1206 # Rationale for this change See the above issues. And this is a follow up to * #6711 * #6873 This was also split out from: #7929 # What changes are included in this PR? This removes the API to allow preserving `dict_id` set in the `Schema`'s `Field` within arrow-ipc and arrow-flight. This is in an effort to remove the `dict_id` field entirely and make it an IPC/flight-only concern. # Are these changes tested? Yes, all existing tests continue to pass. # Are there any user-facing changes? Yes, these previously (in 54.0.0) deprecated functions/fields are removed: * `arrow_ipc::DictionaryTracker.set_dict_id` * `arrow_ipc::DictionaryTracker::new_with_preserve_dict_id` * `arrow_ipc::IpcWriteOptions.with_preserve_dict_id` * `arrow_ipc::IpcWriteOptions.preserve_dict_id` (function and field) * `arrow_ipc::schema_to_fb` * `arrow_ipc::schema_to_bytes`
