`@python/packages/jumpstarter-driver-http-power/jumpstarter_driver_http_power/driver.py`:
- Around line 79-82: Update the authentication handling around the digest
conversion and mutual-exclusion check to use presence checks (`is not None`)
rather than truthiness, so empty Basic or Digest mappings still count as
configured. Apply the same presence-based checks in _build_auth() when selecting
the authentication handler, preserving conversion of configured mappings and
rejecting both configured methods.
- Around line 39-41: Update the HttpDigestAuth configuration fields so user and
password are required during deserialization, removing their empty-string
defaults or applying equivalent presence validation. Preserve the existing
string field types and ensure HttpDigestAuth cannot be constructed from
configuration without both credentials.
- Around line 79-96: Add focused regression tests in driver_test.py covering
_build_auth selecting HTTPDigestAuth, successful Digest challenge/retry behavior
through _make_http_request, and the ValueError raised when basic and digest
credentials are both configured. Keep existing authentication behavior unchanged
and limit changes to the driver logic or test setup required for these cases.
- Around line 84-96: Update _build_auth and the request flow so HTTPDigestAuth
instances are reused for repeated requests to the same compatible endpoint or
origin/realm, preserving their nonce state without sharing handlers across
unrelated URLs. Keep basic authentication behavior unchanged and ensure cached
handlers are invalidated or separated when the target context is incompatible.

Thank you for the contribution @blechschmidt-ldc !, there are a few nits but it's honestly looking good.
The most important to me is the additional testing to validate the digest path.

@blechschmidt-ldc do you have time to handle the comments, or do you want us to handle it from here?, I know it's draft, but really looks close to ready ;) |

Nit: _build_auth lacks a return type annotation. A simple -> Optional[requests.auth.AuthBase] would make the contract explicit and keep the codebase type-checker friendly.

Good catch making the requests dependency explicit. The package was already using import requests but relying on it being transitively available.

Hi again and sorry for the delay. I am still a bit overwhelmed by the pace of AI agent reviews and then other stuff got in between. I have marked the PR as ready now. Please feel free to address remaining issues. |
|
@blechschmidt-ldc it looks great now, thanks for updating it. I've set it for review and I will handle any CI issues if those even exist. |
No worries at all, its always great to see new contribution, and I am happy to lend a hand if necessary. Thanks a lot!! ;) |

The E2E failures is unrelated, will merge this PR as soon as E2E is fixed. |
The HTTP power driver has imported `requests` since it was created without declaring it, so an isolated install only resolved it by accident, through `jumpstarter`. Newer uv no longer exposes undeclared transitive imports in the environment `make pkg-test-*` builds, which makes the target fail with `ModuleNotFoundError: No module named 'requests'`. Declare it explicitly. Relocking pulls in a second, unrelated change: uv.lock was last written by a uv older than 0.11.28, before it began omitting dependency markers that are already implied by a package's own resolution-markers. Regenerating with the uv pinned in .uv-version rewrites 90 such edges. No package versions, sources or hashes change, and the only edges added are the two for requests.

Add an `auth.digest` block to the HTTP power driver config, mapping to
requests' HTTPDigestAuth. It is mutually exclusive with `auth.basic`;
configuring both raises at driver setup.
Check both auth blocks by presence rather than truthiness so an empty
mapping still counts as configured. Previously `auth.basic: {}` next to a
populated `auth.digest` was left unreconstructed, slipped past the
exclusivity check and silently selected Digest.
Reuse one HTTPDigestAuth handler per origin instead of building one per
request. The handler keeps the negotiated nonce in its own state, so a
fresh instance on every call would cost a 401 challenge and retry for each
power operation. Handlers are not shared across origins, whose nonces and
realms are unrelated.
Document the new option in the driver README: a digest example, the
`auth.digest` config row, an HttpDigestAuth parameter table, and an
updated note that no longer claims Basic Auth is the only mechanism.
Cover the digest path in driver_test.py: handler selection per scheme, the
401 challenge and retry, a fixed RFC 2069 response vector, per-origin
handler reuse, reconstruction of dict config, and the mutual-exclusion
error.

I rebased it into main which should have E2E fixed. |

Hi,
some devices like Shelly Power Strip Gen4 only support digest auth. This commit adds digest auth as an alternative means of authentication.
