Description
Accessing a Google Drive folder via the API at the same time may cause it to only return a 502 Bad Gateway afterwards.
Reproduction steps:
- Create a project in osf.io.
- Attach Google Drive to the created project.
- Create a folder (in this case
MultipleObjectTest) under Google Drive. - Acquire a Personal Access Token from the user's Settings.
- Execute the following commands from the user's shell.
$ export OSF_TOKEN=(Personal Access Token obtained.)
$ export NODE_ID=(GUID of the created project)
# Sending requests to the API in three parallel jobs.
$ seq 5 | xargs -P 3 -I{} curl -H "Authorization: Bearer ${OSF_TOKEN}" https://api.osf.io/v2/nodes/${NODE_ID}/files/googledrive/MultipleObjectTest/
After a few runs, it only returns a 502 Bad Gateway.
$ seq 5 | xargs -P 3 -I{} curl -H "Authorization: Bearer ${OSF_TOKEN}" https://api.osf.io/v2/nodes/${NODE_ID}/files/googledrive/MultipleObjectTest/

...
From that point afterwards, a 502 Bad Gateway will be returned for a single request.
When I tried the same test for a container launched by docker-compose as a development environment, the following logs were output.
...
File "./api/nodes/views.py", line 1199, in get_default_queryset
file_ids = [f.id for f in self.bulk_get_file_nodes_from_wb_resp(files_list)]
File "./api/base/views.py", line 642, in bulk_get_file_nodes_from_wb_resp
file_obj = base_class.objects.get(target_object_id=node.id, target_content_type=content_type, _path='/' + attrs['path'].lstrip('/'))
File "/usr/lib/python3.6/site-packages/django/db/models/manager.py", line 85, in manager_method
return getattr(self.get_queryset(), name)(*args, **kwargs)
File "/usr/lib/python3.6/site-packages/django/db/models/query.py", line 384, in get
(self.model._meta.object_name, num)
addons.googledrive.models.MultipleObjectsReturned: get() returned more than one GoogleDriveFile -- it returned 2!
It appears that multiple BaseFileNodes have been created, which would normally be expected to be one for a path.
