sdcubber opened a new issue #1530:
URL: https://github.com/apache/libcloud/issues/1530
## Summary
Mixed-case metadata is lowercased when using libcloud to upload objects to
Google Cloud Storage.
## Detailed Information
I'm using libcloud to upload files to a Google Cloud Storage bucket together
with object metadata.
In the process, the keys in my metadata dict are being lowercased. This is
not due to Google Cloud Storage, which does support mixed case metadata.
The issue can be reproduced following the example from the docs:
```
from libcloud.storage.types import Provider
from libcloud.storage.providers import get_driver
cls = get_driver(Provider.GOOGLE_STORAGE)
driver = cls('SA-EMAIL', './SA.json') # provide service account credentials
here
FILE_PATH = '/home/user/file'
extra = {'meta_data': {'camelCase': 'foo'}}
# Upload with metadata
with open(FILE_PATH, 'rb') as iterator:
obj = driver.upload_object_via_stream(iterator=iterator,
container=container,
object_name='file',
extra=extra)
```
The file uploads succesfully, but resulting metadata will look as follows:
Where `camelCase` has been turned into `camelcase`.
I'm using apache-libcloud==3.0.0 with Python 3.8 on Linux (the python:3.8
Docker image).
Provide detailed information of your bug report.
