Google Drive Python connector

This package implements searchFiles, getFile, readFileText, and uploadFile for Dex Python applications. Both Google OAuth and Workspace domain delegation use manifest-generated credential refresh and Dex project storage. Configure google / google-drive-files in Dex Web Connections, following the connector authorization guide. Do not put access or refresh tokens in Flow input. File timestamps follow Go JSON timestamp validation, including rejection of hour 24 before a file Result is stored.

The text copy example searches by exact source name, reads bounded UTF-8 text, uploads one copy behind a durable dispatch fence, and reads its metadata back. It wires only the successful branch of each operation. Save connections.json from Dex Web and use its path below.

From connectors/google/drive/python, generate the strict FDG 2.0 graph:

uv sync --locked
dexcli visualize examples/text_copy/flow.py --language python \
  --schema-version 2.0 --json --out build/google-drive-python-text-copy \
  --python .venv/bin/python

Start Dex with the generated graph, then run the Worker and Client entrypoints from separate terminals:

dexcli dev -flow-rendering-dir build

DEX_FLOW_SERVICE_ADDRESS=127.0.0.1:8801 \
  DEX_CONNECTOR_CONFIG_FILE=/path/to/connections.json \
  uv run python -m examples.text_copy.main

DEX_FLOW_SERVICE_ADDRESS=127.0.0.1:8801 \
  DEX_CONNECTOR_CONFIG_FILE=/path/to/connections.json \
  uv run python -m examples.text_copy.start \
  google-drive-text-copy-001 examples/text_copy/sample-input.json

Use a new Flow ID for each start. The source must be a text file or a Google Workspace document with a text export. The copy is written to My Drive root. The example's CONNECTION_NAME remains google-drive-files.

The Go-recorded provider scenarios and generated refresh agreement run with:

uv run pytest

With a real dexcli dev service at DEX_FLOW_SERVICE_ADDRESS, run the checked-in Worker and Client integration test:

DEX_FLOW_SERVICE_ADDRESS=127.0.0.1:8801 \
  uv run pytest examples/text_copy/integration_test.py

That test binds its fake provider to an OS-assigned free port. The OAuth consent and Workspace delegated authorization flows against real Google accounts have not been verified for this Python port.
