CompleteMultipartUpload builds the final version and then reads
`final_version.blocks.items()[0]` unconditionally. When the assembled
version ends up with an empty block list the index panics and the
process dies before it can answer the request:
panicked at src/api/s3/multipart.rs:479:3:
index out of bounds: the len is 0 but the index is 0
Use `.first()` and return an internal error instead, matching how the
rest of this file handles missing data. The empty-block case is an
internal consistency condition rather than a malformed request, so it
maps to an internal error rather than a 4xx.
The same panic was reported earlier in #1403, at multipart.rs:483 on
v2.2.0. That report was closed without a fix after the reporter moved
off consistency_mode = "dangerous".
Closes #1521

[ Website and documentation | Binary releases | Git repository | Matrix channel ]
Garage is an S3-compatible distributed object storage service designed for self-hosting at a small-to-medium scale.
Garage is designed for storage clusters composed of nodes running at different physical locations, in order to easily provide a storage service that replicates data at these different locations and stays available even when some servers are unreachable. Garage also focuses on being lightweight, easy to operate, and highly resilient to machine failures.
Garage is built by Deuxfleurs, an experimental small-scale self hosted service provider, which has been using it in production since its first release in 2020.

Garage is entirely free software released under the terms of the AGPLv3.
