Summary

  • Add a superuser-only global POST /api/eda/v1/logs/purge/ endpoint. It returns HTTP 202 with a job_id to acknowledge scheduling; it does not report a synchronous deletion count.
  • Dependency: This PR depends on PR chore(logs): revert bundled log management changes #1716 and should merge after it.

Changes

  • Run API and CLI purges through the shared purge_log_records command, with bounded global deletion batches and opt-in audit entries.
  • Add ISO 8601 retention_duration support and a retention setting that defaults to 0 (no deletion). Keep the CLI --date option; the API rejects before_date.
  • Keep activation IDs and names limited to audit-trail targeting; they do not limit deletion.
  • Queue purges on the default worker queue. Make completion, skipped lock contention, failures, and deleted counts observable in worker logs keyed by job_id.
  • Document the API contract and how operators can inspect purge outcomes.

Test Plan

  • Focused integration tests: task test -- tests/integration/api/test_log_purge.py tests/integration/commands/test_purge_log_records.py tests/integration/tasks/test_management.py tests/integration/api/test_root.py tests/integration/api/test_openapi.py tests/integration/test_advisory_lock.py — 50 passed, 6 skipped, 191 warnings.
  • task lint — passed.

Summary by CodeRabbit

  • New Features
    • Added an administrator-only API for scheduling log purges and receiving a job ID.
    • Purges can use a date or ISO 8601 retention duration and target selected activations or all activations. The command-line tool supports the same cutoff and scope options.
    • Purges run in batches, preserve existing purge markers, and can record audit markers for affected processes. Audit markers are enabled by default and can be disabled.
    • Added a configurable default retention setting; nonpositive values disable default log deletion.
  • Documentation
    • Documented purge options, scope rules, audit markers, and how to inspect job outcomes.

📝 Walkthrough

The change adds log-purge cutoff validation, scoped batched deletion, optional audit markers, asynchronous management-command execution, and a system-admin-only API endpoint for scheduling purge jobs.

Changes: Log purge workflow

Layer / File(s) Summary
Cutoff and scope validation
pyproject.toml, src/aap_eda/core/utils/log_retention.py, src/aap_eda/api/serializers/activation.py, src/aap_eda/core/management/commands/purge_log_records.py, src/aap_eda/settings/defaults.py, tests/integration/commands/test_purge_log_records.py
The API and command accept either an absolute date or an ISO 8601 retention duration. They reject missing or conflicting cutoffs and invalid activation selectors.
Batched deletion and audit markers
src/aap_eda/core/utils/delete_log_util.py, src/aap_eda/core/management/commands/purge_log_records.py, tests/integration/commands/test_purge_log_records.py
The purge utility deletes qualifying logs in batches, excludes purge markers, and can write per-process audit markers. It reports the count already deleted if a later batch fails.
Asynchronous command execution
src/aap_eda/tasks/management.py, tests/integration/tasks/test_management.py, tests/integration/test_advisory_lock.py
The task submits management commands to the default queue. The worker runs commands under an advisory lock and returns skipped, completed, or no-op outcomes.
API scheduling and developer guidance
src/aap_eda/api/serializers/activation.py, src/aap_eda/api/serializers/__init__.py, src/aap_eda/api/views/activation.py, src/aap_eda/api/views/__init__.py, src/aap_eda/api/urls.py, tests/integration/api/*, docs/development.md
The system-admin-only endpoint validates purge requests and returns HTTP 202 with a job ID when scheduling succeeds. Tests cover authorization, validation, task submission, and the OpenAPI schema. The guide describes API and CLI options and job outcomes.

Reconcile the before_date and activation selector contract with the PR description.

The PR description says the API rejects before_date, and that activation IDs and names limit only audit markers, not deletion. LogPurgeRequestSerializer does the opposite. It accepts before_date and can resolve activation selectors that restrict which logs are deleted. The repository's development.md documents this same code behavior, so the code and docs agree and the PR description differs. Decide which contract is intended. Then update the PR description, the documentation, or the serializer to match. Until then, a client that follows the PR description and sends selectors expecting a global purge gets a purge limited to the selected activations.

Hide the purge sentinel from the log API.

ActivationInstanceLogSerializer exposes log_created_at, so purge markers return 9999-12-31T00:00:00Z. Timestamp-based consumers can treat these markers as newer than every real log. Keep the sentinel for internal marker detection, but serialize it as null.

Move global log deletion out of the request path so the API can
acknowledge scheduling without implying that deletion is complete.

- Add a superuser-only global purge endpoint returning HTTP 202
  with a job ID and no synchronous deleted count.
- Validate retention durations before queueing. Keep CLI --date,
  default omitted retention to zero, and reject API before_date.
- Run purges through purge_log_records. Keep the generic
  management-command worker for internal callers, while fixing
  API submissions to the purge command.
- Delete logs globally in bounded batches using an initial
  highest-ID snapshot and report the actual deleted count.
- Make audit creation opt-in. Activation IDs and names select
  audit targets without limiting which logs are deleted.
- Use the default queue, a purge-specific timeout, and an
  advisory lock. Record outcomes and counts in worker results
  and logs.
- Document the API contract, retention and audit behavior, CLI
  options, and operator guidance for checking job outcomes.

Validation:
- task lint
- Focused purge tests: 50 passed, 6 skipped, 191 warnings.

Assisted by: GPT-6
Allow operators to remove old logs for selected activations without
affecting unrelated processes. Bound deletion work and record
per-process counts so partial failures remain traceable.

Validate requests before queueing or deleting, and link audit markers
to the EDA purge job.

Assisted by: GPT-6
Unknown fields could silently turn a scoped request into a global purge. Resolving names before queueing also prevents a later rename from redirecting deletion to another activation.

Assisted by: GPT-6
Customers need a way to clear accumulated logs regardless of age while retaining evidence that a purge occurred. Make this available through the CLI and API using the same purge command.
