Work Description: mosche opened a new pull request #16205:
URL: https://github.com/apache/beam/pull/16205
This bug surfaced when adding integration tests for the S3FileSystem.
Localstack rejected the `uploadPart` request because the MD5 content hash did
not match. This is due to all the additional `\x00` visible in the logs below.
Without these the content hash matches. See details here
https://github.com/localstack/localstack/issues/4987

```
It looks like AWS is a lot more tolerant here and simply ignores any data
beyond the provided content-length.
In any case, we shouldn't be sending this. Also, interestingly, on AWS SDK
v1 the client correctly truncates the data.
Additionally this reduces the memory footprint and improves performance of
the S3 byte channel by avoiding reading the source buffer into an intermediate
temporary array before writing to the upload buffer. If the underlying source
buffer array is accessible, it is used for the optimal performance. Otherwise
the implementation uses a safe alternative based on a read only copy buffer.
