Description of Changes

This PR adds X.509 Certificate Generator Templates, allowing OpenWISP to centrally provision and manage standalone client certificates that are not tied to a VPN. Certificates can now be generated from a template, signed by a chosen certificate authority, inherited from an optional blueprint certificate, exposed to the configuration engine, and revoked or regenerated automatically.

  • Extended the template model with a cert type, a required certificate authority, an optional blueprint certificate, and validation for the new fields.
  • Updated the template admin page to show and validate the certificate fields only for certificate templates.
  • Generated and signed a certificate automatically whenever a certificate template was assigned to a device, and revoked it when unassigned.
  • Regenerated certificates automatically when a device's hostname or MAC address changed, and notified administrators.
  • Exposed the generated certificate, private key, and related values as configuration variables for use in templates.
  • Added support for certificate templates to the REST API, including writable certificate authority and blueprint fields and organization scoping.
  • Documented how to create, assign, and use certificate templates.
  • Added a table on the device admin page listing the automatically generated certificates with links to their full details.
  • Added a new record linking a device configuration, a template, and its generated certificate.

Learning: In this repository, flake8 enforces E501 (line too long) via setup.cfg (max-line-length = 88) while ruff ignores E501 via ruff.toml. Therefore, use '# noqa: E501' on lines that intentionally exceed 88 characters to satisfy flake8 without affecting ruff checks. This applies to Python files across the project (any .py) and is relevant for tests as well. Use sparingly and only where breaking lines is not feasible without hurting readability or functionality.

📝 Walkthrough

Walkthrough

This change adds standalone X.509 Certificate Generator Templates with CA and optional blueprint certificate relations. It creates DeviceCertificate records, generates and revokes certificates during template assignment changes, exposes certificate values in configuration context, and regenerates certificates after device identity changes. It updates REST API and Django admin behavior, adds certificate visibility and deletion restrictions, adds migrations and sample-model support, and documents the feature.

Merge Risk: 🔵 Low · up to 2227f

Rare partial device updates can miss local status bookkeeping, and the new concurrency test may intermittently fail in the configured CI database environment. These are bounded but should be addressed before relying on this change.

Explanation

The PR implements the main requirements in [#1356], [#1357], [#1377], [#1361], [#1410], and [#1362]. It adds certificate templates, CA and blueprint validation, the DeviceCertificate relation, lifecycle handling, API and admin support, device-admin display, tests, and documentation. The rollback regression test is now present. The [#1360] variable contract remains unmet: the certificate UUID is exposed and documented with a cert_{template_hex}_id name, while the issue requires cert_{template_pk_hex}_uuid.

Resolution

Expose the certificate UUID as cert_{template_pk_hex}_uuid in AbstractConfig.get_cert_context(). Update the automated tests and certificate-template documentation to use _uuid. Retain _id only when backward compatibility is intentional and documented.

Full details: Ui Changes, Regression Test, Docs

Explanation

The PR includes end-user UI changes in the admin templates, JavaScript switcher, CSS, and certificate table. The description includes five screenshots, but they show only the new UI states. It does not include a before screenshot or a before-and-after recording. The regression-test requirement is met by added admin, API, model, lifecycle, and Selenium tests. The documentation requirement is met by the new certificate-templates page and related documentation updates.

- Around line 194-198: Update the ordering comment above the receiver
connections near manage_vpn_clients to also state that manage_device_certs must
run before templates_changed because get_cert_context contributes to the
configuration checksum; leave the connection behavior unchanged.

In `@openwisp_controller/config/base/device.py`:
- Around line 306-308: Update the save flow around update_fields and
_check_changed_fields() to materialize any iterable update_fields once before
calling super().save(), then reuse the preserved collection for change
detection. Keep None handling and positional-argument extraction intact,
ensuring generator-based partial saves still trigger set_status_modified() and
retain the updated initial field value.

In `@openwisp_controller/config/tests/test_template.py`:
- Around line 646-707: Run test_concurrent_assignment_and_cert_template_mutation
under a TransactionTestCase-based class instead of TestCase, so setup rows are
committed and visible to the worker-thread connections. Preserve the existing
concurrency assertions and test behavior.

Learning: When reviewing this repo’s Python test suite, treat changes to the *expected* query count in `assertNumQueries(...)` calls as routine test maintenance. If a PR updates the numeric argument (e.g., in `test_config.py`, `test_api.py`, `test_admin.py`, `test_pki.py`) and the test remains consistent with the feature changes, reviewers should not flag the increased number as a performance regression that requires investigation solely because the count went up; instead, focus on whether the update is intentional and the surrounding test/code changes justify the revised expectation.

Learning: In this project’s Python test suite (files under openwisp_controller/**/tests/), don’t require or request prose/inline comments that document the breakdown of query-count changes (e.g., assertions around template/DB query counts in helpers like _verify_template_queries). Treat query-count assertions as volatile implementation details that change frequently; review should focus on whether the test asserts the expected behavior, not on explaining the specific query-count deltas in comments.

AbstractDeviceCertificate.save() wraps certificate creation and persistence in transaction.atomic(). It builds the certificate, saves the signed Cert, assigns it, and saves the DeviceCertificate relation within that scope. manage_device_certs() invokes this through get_or_create(). The transaction-boundary concern is therefore contradicted by the implementation.

99-99: 📐 Maintainability & Code Quality

The claim is refuted by tests/openwisp2/settings.py:295, which sets CONFIG_DEVICECERTIFICATE_MODEL = "sample_config.DeviceCert". This matches tests/openwisp2/sample_config/models.py:99, so the sample model loads correctly without renaming.

openwisp_controller/config/apps.py (1)

225-229: 🩺 Stability & Availability

Cert.clean() calls _validate_bound_cert_organization(), which delegates to DeviceCertificate.validate_cert_bound_organization(self) before the admin form saves the model. The ValidationError therefore reaches model-form validation as a form error. The claim that this check runs only from pre_save and causes an unhandled exception is refuted.

openwisp_controller/config/base/device_certificate.py (1)

224-230: 🎯 Functional Correctness

Template._save() and Template.clean() force auto_cert=True whenever type == "cert". Therefore, active_auto_certs_for() does not need an additional template__auto_cert=True filter. The reported auto_cert=False certificate-template path is not supported by the inspected model behavior.

Extend the ordering comment to cover the certificate receiver.

The comment above manage_vpn_clients states that VPN clients must be managed before templates_changed is evaluated, because the VpnClient context influences the configuration checksum. manage_device_certs has the same ordering requirement, because get_cert_context now feeds the checksum. The comment no longer describes all the ordering-sensitive receivers below it. Record the requirement so a future reorder does not silently break checksum computation.

📝 Proposed comment update
-        # VPN clients must be created or removed **before**
-        # self.config_model.templates_changed is evaluated, because
-        # the VpnClient context can influence the configuration checksum.

Preserve iterable update_fields values before calling super().save().

If a caller supplies a generator, Django consumes it during super().save(). _check_changed_fields() then sees an exhausted iterator. This skips set_status_modified() and leaves the initial field value stale after a valid partial save.

Proposed fix
         update_fields = kwargs.get("update_fields")
+        update_fields_in_kwargs = "update_fields" in kwargs
         if update_fields is None and len(args) > 3:
             update_fields = args[3]

@nemesifier I found one clear AGENTS.md violation.

  • openwisp_controller/config/handlers.py correctly registers the regeneration task with transaction.on_commit().
  • openwisp_controller/config/tests/test_device.py verifies callback execution after commit.
  • The tests do not verify rollback behavior.

AGENTS.md requires tests for both commit and rollback behavior when a Celery task depends on database changes in the current transaction. Add a test that changes Device.name or Device.mac_address inside transaction.atomic(), rolls back the transaction, and asserts that regenerate_device_certificates_task.delay() was not called.

Additional checks:

  • git diff --check found no whitespace errors.
  • The Python/Django CI matrix passed on all listed versions.
  • Coveralls currently fails because total coverage decreased from 98.362% to 98.089%. This is a failing quality gate, but it is not a direct AGENTS.md rule violation.

@stktyagi Recheck complete.

  • UI Changes: Pass. The PR description now includes clear screenshots for all main UI flows. The Selenium tests cover certificate provisioning, template-field visibility, auto_cert switching behavior, and regeneration notifications.
  • Docs: Pass. The new certificate-template guide is in the documentation index. It covers setup, lifecycle behavior, configuration variables, settings, and REST API use.
  • Regression Test: Not ready. The Python/Django CI matrix passes. However, openwisp_controller/config/tests/test_device.py still has no rollback test for the transaction.on_commit() callback that queues regenerate_device_certificates_task.delay(). This remains the AGENTS.md gap from the prior review.
  • Quality gate: Coveralls still fails because coverage decreased to 98.089%.

Please add the rollback regression test and restore the required coverage before merge.

@stktyagi I found one remaining AGENTS.md violation.

The two merge commit subjects are not in past tense:

  • Merge branch 'master' into gsoc26-x509-certificate-generator-templates
  • Merge remote-tracking branch 'origin/master' into gsoc26-x509-certificate-generator-templates

AGENTS.md requires descriptive commit messages in past tense. The automated openwisp-commit --check validation was unavailable in this environment.

The prior rollback-test violation is resolved. test_rollback_discards_queued_regeneration verifies that rollback does not call regenerate_device_certificates_task.delay().

The inspected PR checks pass. This includes the Python/Django matrix, Coveralls, and git diff --check. I found no other confirmed AGENTS.md violation.

@stktyagi The Linked issues concern is resolved.

GitHub recognizes all required closing references for this PR:

The issues remain open because GitHub closes Closes #<number> references only after PR #1486 merges. This is expected behavior.

The current PR checks also pass, including Coveralls at 98.535%. I withdraw the Linked issues warning.
