Bug #11226
Updated by Tom Clegg over 7 years ago
The Python SDK instructs httplib2 to cache the discovery document in @~/.cache/arvados/discovery@. However, the google API client code also has its own cache logic, which caches the discovery document in @/tmp/google-api-python-client-discovery-doc.cache@. This is a problem particularly on a multi-user system such as a shell node. The file gets created in a global location like /tmp, then only the original user can update the file. From looking at the google-api-python-client code, the destination is chosen as @os.path.join(tempfile.gettempdir(), FILENAME)@ where @FILENAME = 'google-api-python-client-discovery-doc.cache'@ https://github.com/google/google-api-python-client/blob/dc6c1efea8e6c89afa94df984d9291359cb04797/googleapiclient/discovery_cache/file_cache.py#L87 h3. Proposed fix See note-6. In the Python SDK, set tempfile.tempdir to @~/.cache/arvados/{conn-hash}@ before doing anything with google-api-client.
