Problem: Large downloads from FS fail since file ends up being loaded into memory despite iteration

[carlosmcgregor]

Expected behaviour

Large download from FS is streamed (or equivalent) successfully.

Current behaviour

Large download from FS ends up loading the large file into memory, causing it to throw a 502 status code.

Steps to reproduce

1. Prepare a large archival package
2. Attempt to download it from FS

Solution

A temporary fix to this issue that currently fits our need is to change the HttpResponse to a StreamingHttpResponse here:
https://github.com/artefactual/archivematica/blob/qa/1.x/src/dashboard/src/components/helpers.py#L269

To my understanding (and unfortunately) this would cause a Django worker to be blocked while streaming.

Your environment (version of Archivematica, operating system, other relevant details)

• Archivematica: 1.14.0 - 1.16.0
• OS: Ubuntu 22.04
