From 6addd575192794ebb2be74280826b26d5314baba Mon Sep 17 00:00:00 2001 From: Mike Bridge Date: Mon, 4 May 2026 09:54:25 -0600 Subject: [PATCH 001/114] refactor(db): composite PK on M2M association tables (sc-105349) Replace synthetic id INTEGER PRIMARY KEY with composite PRIMARY KEY (fk1, fk2) on the eight pure-junction tables: dashboard_roles, dashboard_slices, dashboard_user, report_schedule_user, rls_filter_roles, rls_filter_tables, slice_user, sqlatable_user. The redundant UNIQUE(fk1, fk2) on dashboard_slices and report_schedule_user is dropped (subsumed by the new PK). Migration handles dialect quirks: copy_from for tables with pre-existing UNIQUE (so SQLite's anonymous-constraint reflection doesn't matter), wrapped- subquery dedupe for MySQL (ERROR 1093), sa.Identity(always=False) on downgrade to backfill the restored id column without NOT NULL violations, and distinct PK names per direction (pk_ on upgrade,
_pkey on downgrade) to avoid round-trip index-name collisions on Postgres. ORM Table() definitions updated to match. UPDATING.md entry added with operator runbook (BI-tool impact, pre-flight inventory queries, dedupe-row- loss notice, pg_dump workaround, FK-NOT-NULL downgrade asymmetry note). Tests: 8 schema-shape assertions (post-upgrade), 8 duplicate-rejection unit tests, 8 distinct-pair sanity tests, 1 round-trip + idempotency test (in-memory SQLite via Alembic MigrationContext). Continuum-restore verification against the new shape is out of scope for this PR; it is the responsibility of the versioning epic (sc-103156).

The FK columns themselves are unchanged. + +**Pre-flight inventory queries.** Before applying the upgrade, operators are encouraged to run the queries below against their database to assess what the migration will change. Two classes of pre-existing data are not preserved by the migration: duplicate `(fk1, fk2)` rows (the migration keeps `MIN(id)` and deletes the rest) and rows with `NULL` in either FK column (the migration deletes them, since FK columns are promoted to `NOT NULL` for the composite PK).

Restoring such a dump against the post-migration schema will fail. The supported workaround is to dump only the schema and reference data, then re-create the M:N associations from application data after restore — for example with `pg_dump --exclude-table-data` (or per-table `--exclude-table-data=dashboard_slices` etc.) for the eight junction tables, restore the rest, then run a one-shot script that re-INSERTs `(fk1, fk2)` pairs derived from your application export. Operators who need to restore an old dump verbatim should restore against a pre-migration Superset and then re-run the upgrade. + +**Intentional downgrade asymmetry.** The migration's `downgrade()` restores the surrogate `id` column and (for `dashboard_slices` and `report_schedule_user`) the original `UNIQUE (fk1, fk2)` constraint, but it does **not** restore the original `NULL`-allowed state on the FK columns — they remain `NOT NULL`. This is intentional: under SQLAlchemy's `secondary=` semantics, a `NULL` in either FK column of a junction table is meaningless (it cannot participate in either side of the relationship). Operators downgrading are not expected to need this restored. The asymmetry is documented for completeness so that round-trip schema diffs are not mistaken for migration bugs. + ## 6.0.0 - [33055](https://github.com/apache/superset/pull/33055): Upgrades Flask-AppBuilder to 5.0.0. The AUTH_OID authentication type has been deprecated and is no longer available as an option in Flask-AppBuilder. OpenID (OID) is considered a deprecated authentication protocol - if you are using AUTH_OID, you will need to migrate to an alternative authentication method such as OAuth, LDAP, or database authentication before upgrading. - [34871](https://github.com/apache/superset/pull/34871): Fixed Jest test hanging issue from Ant Design v5 upgrade.

A production database with a stray NULL ``dashboard_id`` row would have failed the PK-add with a cryptic constraint violation. Fix by running the NULL-FK cleanup on every affected table — it is a no-op DELETE on tables whose FK columns are already NOT NULL, and it eliminates the risk of further drift in the hardcoded set. ``dashboard_roles`` is added to the documentation set; the runtime now does not consult it. 2. The unit-test parent-table name for ``rls_filter_roles`` and ``rls_filter_tables`` was ``rls_filter`` (does not exist) instead of the real parent ``row_level_security_filters``. Test passes either way (the in-memory FK is self-consistent), but the parameter is now accurate.

The single-schema case (Superset's documented deployment) is fully covered. 4. ``_dedupe_by_min_id`` now logs a sample of up to 10 discarded ``(fk1, fk2, id)`` tuples at WARN before deletion, so operators can audit which rows the ``MIN(id)`` policy drops. The keep- original policy is correct in practice but discards later re-grants on ownership tables; the sample makes that visible. 5. ``UPDATING.md`` documents the upgrade/downgrade primary-key name divergence (``pk_
`` vs ``
_pkey``) so operators using schema-comparison tools don't mistake it for migration drift. No schema or runtime-behaviour changes. All 44 migration tests pass.

This is intentional: under SQLAlchemy's `secondary=` semantics, a `NULL` in either FK column of a junction table is meaningless (it cannot participate in either side of the relationship). Operators downgrading are not expected to need this restored.

_pkey` (PostgreSQL's default convention for `PrimaryKeyConstraint("id")`). The two names alternate so that a round-trip (upgrade → downgrade → upgrade) does not collide on a pre-existing constraint name. Operators using schema-comparison tools (e.g. `pg_diff`, `migra`) against a downgraded database may see this as drift versus a fresh-install schema.

InnoDB uses the composite PK index to back the FK on the leftmost column. The downgrade tried to drop the composite PK before dropping the FKs, orphaning the FK's backing index. PostgreSQL and SQLite create separate indexes for FK columns and don't trip on this. 2. ``Field 'id' doesn't have a default value`` on subsequent INSERT. ``sa.Identity(always=False)`` only emits ``AUTO_INCREMENT`` on MySQL when the column is created with ``primary_key=True`` — our portable path adds the column first then creates the PK separately, so MySQL leaves the column without auto-generation. Existing rows would all collide on id=0; future inserts fail because no default. Postgres' ``GENERATED BY DEFAULT AS IDENTITY`` and SQLite's ``INTEGER PRIMARY KEY`` rowid alias don't have this gap. Fix: extract ``_downgrade_mysql_table()`` that emits the canonical MySQL idiom — drop FKs, then a single ALTER combining ``DROP PRIMARY KEY, ADD COLUMN id INT NOT NULL AUTO_INCREMENT, ADD PRIMARY KEY (id)`` (which backfills existing rows with sequential ids and preserves AUTO_INCREMENT), restore the redundant UNIQUE on the 2 tables that originally had it, and re-add the FKs with their original names. Postgres and SQLite keep the existing portable ``batch_alter_table`` path. Raw SQL is unavoidable for the combined-ALTER form; per the constitution it's allowed for dialect-specific DDL with no SQLA equivalent, with triple-quoted strings for legibility. Verified end-to-end: upgrade → downgrade → upgrade against a fresh MySQL 8 container with INSERT-without-id sanity check showing the restored ``id`` column auto-increments correctly.

The simple per-table COUNT/duplicate/NULL queries that were already there are dialect-portable but only count rows; operators on PostgreSQL with large deployments need to characterize the migration's runtime cost before scheduling it. Adds four diagnostic queries: - Per-table size, row count (from pg_class.reltuples), and which migration path each table will take (recreate-rewrite vs direct ALTER). Sizes the work concretely. - Aggregated duplicate-row roll-up: dup_groups + total rows_dropped per table. Replaces eight separate per-table queries with one consolidated result for audit/dump-before-apply decisions. - External-FK pre-flight check (the same one the migration runs at upgrade time and aborts on). Lets operators surface any blocking external reference ahead of the maintenance window. Should be empty on a stock install. - Lock-window estimate for the two full-rewrite tables, using pg_relation_size and a conservative 100 MB/s rewrite throughput assumption. The other six use direct ALTER and are dominated by composite-index build time (seconds for low-millions-of-rows tables). Prompted by reviewer feedback on apache/superset#39859 from a large deployment asking how to size the maintenance window. The original pre-flight queries are kept for cross-dialect operators (MySQL, SQLite) since the new queries use PostgreSQL-specific catalog views.

The lock-window estimate query is updated to cover all eight rather than just two, and the "migration_path" column makes the rebuild expectation explicit ("direct ALTER (still rebuilds InnoDB clustered index)"). Other notes: - ``information_schema.TABLES.TABLE_ROWS`` is an InnoDB estimate, analogous to PostgreSQL's ``reltuples``; documented inline. - ``KEY_COLUMN_USAGE`` carries both sides of the FK in a single row on MySQL, so the external-FK pre-flight check is simpler than the PostgreSQL version (no joins between three views). - The aggregated dedupe query is portable standard SQL; included verbatim for copy-paste convenience.

Mirrors the connection settings used by CI's ``test-mysql`` shard: ``mysql+mysqldb`` dialect, charset ``utf8mb4`` with binary_prefix. Host port defaults to 13306 (configurable via ``DATABASE_PORT_MYSQL``) to avoid colliding with a native MySQL install on 3306. A separate volume (``db_home_mysql``) keeps MySQL data isolated from the Postgres ``db_home`` volume, so switching between the two with ``-f`` flag toggles doesn't corrupt either side. The Postgres-specific init scripts under ``docker/docker-entrypoint-initdb.d/`` are not mounted on the MySQL service (they are postgres-only). Examples / cypress fixtures still load via ``superset-init``'s post-startup steps, which run ``superset load-examples`` against whichever metadata DB is in use.

Fix: add ``EXAMPLES_HOST/PORT/DB/USER/PASSWORD`` and a complete ``SUPERSET__SQLALCHEMY_EXAMPLES_URI`` to the ``mysql-env`` anchor. 2. The Postgres init scripts under ``docker/docker-entrypoint-initdb.d/`` (``cypress-init.sh``, ``examples-init.sh``) get mounted on the MySQL container too — compose merges volume lists. They invoke ``psql`` which doesn't exist in the MySQL image, abort with ``psql: command not found``, and prevent the ``examples`` DB from being created. Fix: add a MySQL-specific init script ``docker/mysql-init/examples-init.sql`` that creates the ``examples`` database and user, and mount it at ``/docker-entrypoint-initdb.d`` in the override. Compose's later-takes-precedence rule on duplicate volume targets displaces the Postgres init dir, so the MySQL container only sees the MySQL-compatible script. (Used a plain duplicate-target mount rather than the ``!override`` tag because pre-commit's ``check-yaml`` doesn't recognize Compose's custom YAML tags.) Recovery for an existing failed MySQL stack: ``docker compose -f docker-compose.yml -f docker-compose-mysql.yml down``, then ``docker volume rm superset_db_home_mysql`` (so the new init script runs on the next fresh boot), then ``up`` again.

Designed for measuring migration runtime at varying scales — run with a series of size flags (100K / 1M / 5M / 10M for the target table) and time the migration at each scale to verify the predicted ``O(N log N)`` extrapolation against real numbers. Properties: - **Reproducible**: deterministic cross-product walk through parent IDs produces a stable pair sequence; re-running is replayable. - **Idempotent**: re-running with the same target is a no-op; with a higher target, only new rows are added. - **Backend-agnostic**: connects via Superset's standard ``DATABASE_*`` env vars (or ``SUPERSET__SQLALCHEMY_DATABASE_URI``). Branches on dialect for ``BINARY(16)`` vs ``UUID`` vs TEXT/BLOB UUID columns. - **Batched**: bulk INSERT 10K rows per statement. - **Per-phase timing**: logs elapsed wall time for the parents phase, the junctions phase as a whole, and per junction-table. - **Avoidance set**: loads existing junction pairs into a Python set so re-runs on top of pre-existing data don't collide on the uniqueness constraint. Usage (inside the Superset container): docker exec superset-superset-1 \\ /app/.venv/bin/python /app/scripts/seed_junction_load.py \\ --dashboard-slices 1000000 Defaults target a "large multi-team install" shape: 1M ``dashboard_slices``, 100K each ``slice_user`` / ``dashboard_user``, 10K ``dashboard_roles``. Override per-table via flags. Tested locally on MySQL (the user's current eval stack): - 200/100/100/50 row mini-run produced expected counts. - Re-running at the same target is a no-op (idempotent). - ``--dry-run`` plans without writing. Junction tables not yet covered (``sqlatable_user``, ``rls_filter_*``, ``report_schedule_user``) are typically small in production and require additional parent seeding (RLS filters, report schedules) that wasn't worth the scope here. Adding them is straightforward by extending ``JUNCTIONS`` and writing the corresponding parent seeder.

Usage: after running the normal seed at a given scale, add ``--dirty-duplicates-pct 5`` (or any non-zero value) to inject that percentage of duplicate ``(fk1, fk2)`` rows into each non-UNIQUE junction (slice_user, dashboard_user, dashboard_roles — dashboard_slices is skipped because its UNIQUE constraint, present both pre- and post-migration, rejects duplicates). Pre-condition: requires the DB to be at the pre-migration revision (33d7e0e21daa). The post-migration composite PK rejects duplicates, so attempting to inject on the upgraded schema errors out. Empirical result on MySQL @ 10M dashboard_slices + ~2.1M other junction rows + 105K injected duplicates (5% on the 3 non-UNIQUE tables): Upgrade time: 1m 36s vs clean baseline 1m 37s → dedupe cost is within measurement noise; the table-scan that the migration already performs dominates whether or not duplicates exist. This empirically confirms what the cost-model predicted: the ``_dedupe_by_min_id`` GROUP BY scan is the dominant cost of that phase, and the actual per-duplicate DELETE is negligible. NULL-FK injection deliberately skipped — would require altering the six non-UNIQUE FK columns from NOT NULL back to nullable (the migration's downgrade keeps them NOT NULL by design), which adds per-backend ALTER complexity for a code path that's structurally identical in cost shape (DELETE WHERE col IS NULL is the same scan shape as the dedupe scan).

MySQL 8 rejects this with ERROR 1832 when the table has data — even when the change is just ``NULL`` → ``NOT NULL`` and the column is already part of a freshly-added composite primary key (which InnoDB has just made implicitly NOT NULL anyway). The error fires on populated tables only; CI's ``test-mysql`` shard runs against empty tables and so didn't catch this, while a real production-shaped install does. The ``alter_column`` was only ever needed for SQLite, where composite ``PRIMARY KEY`` does not promote constituent columns to ``NOT NULL`` (a long-standing SQLite quirk — only ``INTEGER PRIMARY KEY`` does). PostgreSQL and MySQL implicitly promote PK columns to ``NOT NULL`` as part of ``ADD PRIMARY KEY``, so the explicit step is unnecessary on both — and on MySQL it's actively broken on populated tables. Fix: extract the ``alter_column`` pair into a helper ``_enforce_not_null_for_sqlite()`` that no-ops on Postgres and MySQL. Both branches of the per-table upgrade (the ``recreate="always"`` path for the two UNIQUE-bearing tables, and the direct-ALTER path for the other six) now call the helper instead of inlining the ``alter_column``. Verified end-to-end: downgrade-then-upgrade against MySQL with ~12M total junction rows (10M dashboard_slices + 1M each slice_user/dashboard_user + 100K dashboard_roles) completes in 1m 39s with no ERROR 1832. The 44 in-memory SQLite tests still pass. Considered Justin's alternative (drop FKs on MySQL across all eight tables, unifying the two branches) but rejected as more invasive — it would require capturing FK metadata and explicitly re-creating the FKs for the six non-recreate tables, since they don't go through the ``copy_from`` path that re-creates FKs automatically. The SQLite-only approach is more targeted: it removes the operation that MySQL rejects rather than working around the rejection.

MySQL/InnoDB always assigns FK names, so this branch was defensive, but the asymmetry was confusing. Symmetrized via ``continue`` at the top of the re-add loop. 2. **``ondelete`` whitelist before raw-SQL interpolation** The value comes from MySQL's ``information_schema`` (not user input), but interpolating a reflected string into raw SQL without a guard left a "what if an unexpected value appears" footgun. Added ``_VALID_ONDELETE_ACTIONS`` (the four SQL-standard actions) and a ``RuntimeError`` when an unexpected value is reflected. 3. **Direct ALTER on PostgreSQL for tables with pre-existing UNIQUE** ``recreate="always"`` is dialect-agnostic — on PostgreSQL it triggers ``CREATE TABLE AS SELECT → DROP → RENAME`` holding ``ACCESS EXCLUSIVE`` for the full table-copy duration. For a multi-million-row ``dashboard_slices``, that lock window can be noticeable. The reflected UNIQUE constraint has a stable name on PostgreSQL (default ``
__key`` convention), so dropping it directly and then running structural change as direct ALTER avoids the copy entirely. The reflected UNIQUE name is wrapped in a new ``_drop_redundant_unique_by_name()`` helper. Postgres takes the direct path; MySQL keeps ``recreate="always"`` because InnoDB binds FKs to the UNIQUE's underlying index for back-reference (``DROP CONSTRAINT`` on the UNIQUE there raises ``ERROR 1553``); SQLite keeps ``recreate="always"`` because unnamed UNIQUEs reflect with ``name=None`` and can't be dropped by name. Verified end-to-end: downgrade-then-upgrade against MySQL with ~12M total junction rows seeded completes in ~1m 41s (within the range of the prior measurements).

Replaces three iterative spike-phase migrations (56cd24c07170, e1f3c5a7b9d0, f7a2b3c4d5e6) so downstream operators see one migration to apply or reverse and one review surface. Hash retained from the original first migration so anyone still tracking the chain by that hash lands on the same logical change set. Tables created (eight total): version_transaction (audit log keyed by Continuum's per-flush transaction id, plus a Postgres-only id_seq), version_changes (field-level diff log), three parent shadow tables (dashboards_version / slices_version / tables_version), and three child shadow tables (table_columns_version / sql_metrics_version / dashboard_slices_version). Downgrade drops all eight in FK-reverse order plus the Postgres sequence. Primary key choice. version_transaction.id and version_changes.id are BigInteger autoincrement — a deliberate carveout from the project's UUID-PK convention. version_transaction is keyed externally by SQLAlchemy-Continuum via nextval('version_transaction_id_seq') on every INSERT; matching that contract is required for versioning_manager to function. version_changes follows the same shape because the user-facing identity is the (transaction_id, entity_kind, entity_id, sequence) composite unique key, not the row id; the API surfaces a deterministic UUIDv5 version_uuid derived from entity.uuid and transaction_id for stable external references.

Audit columns are pinned when force-flagging the parent dirty so onupdate hooks don't fire spuriously; the flag_modified-suppresses-onupdate invariant is locked in by test. Slice, Dashboard, SqlaTable, TableColumn, and SqlMetric carry __versioned__ declarations so SQLAlchemy-Continuum builds shadow classes for each. The slices exclude is dropped from Dashboard.__versioned__ so dashboard_slices membership is captured in the timeline.

Adds versioning/queries.py (per-version row construction for the API response shape), versioning/utils.py (read_row_outside_flush + small shared helpers), versioning/schemas.py (Marshmallow response schemas), and the package __init__.py. Unit tests for the diff engine live in tests/unit_tests/versioning/test_diff.py and cover both scalar-field and JSON-blob walking.

Without this the runtime attribute access (tx_tbl.c.action_kind) fails and the change-record listener cannot stamp the transaction-scope action_kind. Baseline listener captures pre-existing rows on first save so the timeline isn't missing transaction-0; uses session.no_autoflush around the live-row reads to avoid the implicit flush that would otherwise push the in-progress save before its own pre-state is captured.

Records accumulated across multiple before_flush calls within one transaction share the same transaction_id and contiguous sequence numbers. Three-dimension schema. The version_changes row carries kind (content category, per record) and operation (verb, per record). The transaction-scope action_kind ("restore" / "import" / "clone" / NULL) is stamped onto version_transaction.action_kind via sa.update() — dialect-portable through the SQLAlchemy core compiler's identifier quoting, not f-string SQL. Commands declare the avenue by writing session.info[ACTION_KIND_KEY] immediately before db.session.commit(). Cleanup. The listener pops the action_kind key after stamping (primary lifecycle); an after_rollback listener pops it again as a safety net so a long-lived session cannot inherit a stale action_kind into the next transaction. Regression test test_action_kind_dropped_on_rollback pins this down.

This must run before the flush because after the + flush the DB already reflects the post-state; we can't recover the + pre-state from it. + +- ``after_flush``: drains the buffer, resolves the current Continuum + transaction id via ``versioning_manager.units_of_work``, and bulk- + inserts one ``version_changes`` row per record with a monotonic + ``sequence`` number. Records accumulated across multiple before_flush + calls within one transaction share the same ``transaction_id`` and + contiguous sequence numbers. + +Scope in this iteration: + - Slice, Dashboard, SqlaTable **scalar fields** (via + :func:`scalar_fields_for` — new columns are picked up automatically + without editing this module). + - ``Slice.params`` kind-classification (filter / metric / time_range / + color_palette / dimension, plus generic ``field`` fallback). + +Child-collection diffs (dataset ``TableColumn`` / ``SqlMetric``, +dashboard ``dashboard_slices``) read the pre- and post-state from +Continuum shadow tables via :func:`_shadow_rows_valid_at`, executed in +``after_flush`` once Continuum has written its tx-N rows. + +``session.new`` entities are not processed in this listener: +operation_type=0 transactions (baseline capture and first-save INSERTs) +produce zero change records per spec §Clarifications 2026-04-24. + +**Inline imports.** Several helpers below use ``# pylint: disable= +import-outside-toplevel`` for imports of ``sqlalchemy_continuum`` and +Superset model classes.

From 5d5a28986ca031afc0dfc954018e2c5307f2f0c3 Mon Sep 17 00:00:00 2001 From: Mike Bridge Date: Tue, 2 Jun 2026 14:48:59 -0600 Subject: [PATCH 026/114] feat(versioning): restore-version commands for chart, dashboard, dataset BaseRestoreVersionCommand defines the workflow for a non-destructive version restore on one entity. Subclasses declare the model class plus the three entity-specific exception classes (not_found / forbidden / failed); each subclass decorates run() with @transaction(on_error=...) so the transactional commit boundary maps to the right HTTP-level error. Each command stamps session.info[ACTION_KIND_KEY] = "restore" before db.session.commit() so the change-record listener writes version_transaction.action_kind = "restore" on the resulting Continuum transaction. Reuses the resource's existing can_write permission; workspace admins can list and restore any entity.

Authorisation reuses can_write on the resource. Existing copy / duplicate / import / asset-import commands stamp session.info[ACTION_KIND_KEY] before commit ("clone" / "import") so the timeline reads "Cloned from " or "Imported from " instead of "Created". Method-scoped imports of ACTION_KIND_KEY carry a one-line justification noting the versioning bootstrap defer pattern documented in changes.py.

Authorisation reuses the resource's existing `can_write` permission; workspace admins can list/restore any entity. + +**Version response shape — `changes` array:** + +Each entry returned by `GET /api/v1/{resource}//versions/` and `GET .../versions//` includes a `changes` array describing what changed relative to the previous version: + +```json +"changes": [ + {"kind": "field", "path": "slice_name", "from_value": "Old", "to_value": "New"} +] +``` + +The array is empty for baseline (`operation_type=0`) transactions. `kind` enumerates structured record types (`field`, layout-walker records for dashboards, dataset child diffs for `TableColumn` / `SqlMetric`); `path` is a dotted JSON-pointer-style locator; `from_value` / `to_value` are JSON-safe scalars or compact records. + +**Save-response and ETag headers:** + +- Save responses (`PUT /api/v1/{resource}/`) include `old_version_uuid` and `new_version_uuid` body fields so the client can correlate a save with its resulting version row. +- All entity GETs (`GET /api/v1/{chart,dashboard,dataset}/`), version-list GETs, single-version GETs, and save responses emit an `ETag: ""` header reflecting the entity's current live version. The default `CORS_OPTIONS` now sets `expose_headers: ["ETag"]` so cross-origin browser clients can read the header. **No `If-Match` enforcement in v1** — `ETag` is informational; concurrent-edit detection is deferred to a follow-up SIP. +- **Operators overriding `CORS_OPTIONS` in `superset_config.py` MUST include `"expose_headers": ["ETag"]`** (or merge with the default) for cross-origin clients to read the ETag. A bare `CORS_OPTIONS = {"origins": [...]}` will silently drop the expose-headers default. + +**Behaviour changes on save:** + +- Every save of a chart, dashboard, or dataset produces one new version row. Rows preserve the full post-save state (scalar fields for all three entity types; `TableColumn` / `SqlMetric` children for datasets; `dashboard_slices` chart membership for dashboards — children versioned via SQLAlchemy-Continuum shadow tables `table_columns_version`, `sql_metrics_version`, and `dashboard_slices_version`). +- First save after an entity already exists in the DB creates a retroactive baseline version so the UI can show "what this looked like before I edited it." +- Tags, owners, and roles are **not** versioned in v1 (ADR-005). A restore leaves those at their live values. + +**New config key:** + +| Key | Default | Purpose | +|---|---|---| +| `SUPERSET_VERSION_HISTORY_RETENTION_DAYS` | `30` | Versions older than this many days are pruned by a nightly Celery beat task (`superset.tasks.version_history_retention.prune_old_versions`). Each entity's live row (`end_transaction_id IS NULL`) is always preserved; closed historical rows including the baseline age out with the rest. Set to `0` to disable retention entirely. | + +**Impact on external integrations:** + +- New tables populated on every save — `dashboards_version`, `slices_version`, `tables_version` (parent shadow tables for the three entity types), `table_columns_version`, `sql_metrics_version`, `dashboard_slices_version` (child shadow tables), plus the shared `version_transaction` and `version_changes` tables. External tooling that queries Superset's DB directly will see writes to these tables proportional to save traffic. +- Existing entity endpoints (`GET`/`PUT /api/v1/{chart,dashboard,dataset}/`) gain an `ETag` response header and the save response gains `old_version_uuid` / `new_version_uuid` body fields. No existing fields are removed or repurposed. +- Version capture is always active — no feature flag. + ### Granular Export Controls A new feature flag `GRANULAR_EXPORT_CONTROLS` introduces three fine-grained permissions that replace the legacy `can_csv` permission: From 72f3a9b65cefc5259c7c52321ef33d2a965ffb45 Mon Sep 17 00:00:00 2001 From: Mike Bridge Date: Tue, 2 Jun 2026 14:49:25 -0600 Subject: [PATCH 031/114] temp(versioning): demo version-history dropdowns + French i18n MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Throwaway frontend dropdowns wired into the three resource list pages plus updated French i18n catalog.

B1 — Inline imports in /versions endpoints moved to module top. ``charts/api.py`` / ``dashboards/api.py`` / ``datasets/api.py`` carried 14 in-method imports of ``UUID`` / ``VersionDAO`` / ``SupersetSecurityException`` / ``set_version_etag`` / ``set_version_etag_by_uuid`` with only ``# pylint: disable= import-outside-toplevel`` and no circular-import justification. All four targets are import-side-effect-free at module load (stdlib; exception class; DAO module; pure ETag helpers), so the right fix is the move, not the comment. Inline duplicates removed across all three files; ruff auto-sorted the new top-level positions. H1 — Restore stamps ``changed_on`` with ``datetime.utcnow()``. ``_stamp_audit_fields_for_restore`` in ``versioning/restore.py`` previously called ``datetime.now()``, making the timestamp dependent on server local timezone — skews ordering/audit/comparison across multi-node deployments. Switched to ``datetime.utcnow()`` consistent with the audit-mixin convention. While there, hoisted the inline ``datetime`` and ``get_user_id`` imports to module top. M1 — ``list_versions`` and ``get_version`` mapped to ``"read"``. In ``constants.py`` MODEL_API_RW_METHOD_PERMISSION_MAP, the two GET endpoints were ``"write"`` — stricter than REST convention and unable to express the common pattern "reader can see history; only writer can restore". ``restore_version`` remains ``"write"``. M2 — Object-level check switched to ``raise_for_access``. The six GET endpoints (chart / dashboard / dataset, list/get each) previously called ``security_manager.raise_for_ownership(entity)`` — appropriate for write paths but stricter than necessary for read. Switched to ``raise_for_access(chart=)`` / ``(dashboard=)`` / ``(datasource=)`` so the route flows through the standard role-and- capability matrix in ``SECURITY.md`` and lets viewers who can see the entity also see its history. N1 — ``Optional[Any]`` → ``Any | None`` in ``restore.py``. Aligns with the project's Python 3.10+ union-type convention. UPDATING.md updated to document the new permission model (``can_read`` for list/get, ``can_write`` for restore, enforced via ``raise_for_access``).

Extract three handler functions in ``superset/versioning/api_helpers.py``: ``list_versions_endpoint``, ``get_version_endpoint``, ``restore_version_endpoint``. Each per-resource method now delegates in 3-12 lines; the FAB decorators (``@expose`` / ``@protect`` / ``@safe`` / ``@statsd_metrics`` / ``@event_logger.log_this_with_context``) and the OpenAPI docstrings stay at the method site where they belong. Eliminates ~330 lines of duplication across the three resource API files. Flagged independently by clean-code-review (G5 / SRP at the endpoint layer) and tidy-first-review (Extract Helper — VersioningEndpointMixin). The activity-view's ``resolve_endpoint_path_entity`` helper on sc-107283 does only the path-entity resolution step; consolidating with the new ``_resolve_entity`` in api_helpers is a follow-up after the sc-107283 rebase.

Coercing + defensively here makes the in-memory attribute always a UUID + regardless of provenance. + + **Why the non-UUID-string escape hatch.** Tightening this + validator to raise on non-UUID strings would break a small set + of existing unit tests that use human-readable placeholder + strings as fixture uuids (e.g. + ``test_dashboard_schemas.py``'s ``"dashboard-uuid-7"`` and + analogous placeholders in importer tests).

Split it into four submodules along those existing boundaries: * ``changes/table.py`` (~85 LOC) — the ``version_changes_table`` ``sa.Table`` definition plus the ``_ENTITY_KIND_BY_CLASS_NAME`` mapping. Schema-only; no logic. * ``changes/state.py`` (~210 LOC) — per-entity diff dispatch: ``_jsonable`` JSON-safety coercion, ``_orm_to_post_state``, ``_read_pre_state``, ``_compute_records_for_entity`` (string-dispatch to ``diff_slice`` / ``diff_dashboard`` / ``diff_dataset``), ``_bulk_insert_records``, and the cached scalar-field set. * ``changes/shadow_queries.py`` (~225 LOC) — Continuum shadow-table reads for child-collection diffs: ``_shadow_rows_valid_at``, ``_affected_{dataset,dashboard}_ids_at_tx``, ``_{dataset,dashboard}_child_records_for_tx_from_shadows``, ``_dashboard_slice_uuids_at_tx``. * ``changes/listener.py`` (~290 LOC) — the SQLAlchemy event listener machinery: ``register_change_record_listener`` (public), the four flush/commit/rollback handlers, ``ACTION_KIND_KEY`` and the buffer- key constants, the per-tx action-kind stamper. ``changes/__init__.py`` re-exports the five symbols imported across package boundaries (``ACTION_KIND_KEY``, ``register_change_record_listener``, ``version_changes_table``, ``_ENTITY_KIND_BY_CLASS_NAME``, ``_shadow_rows_valid_at``), so every existing ``from superset.versioning.changes import …`` site continues to work without change. Listener registration order — load-bearing per SIP-210 — is preserved: the four ``event.listen`` calls in ``register_change_record_listener`` keep the same order, and the function itself is unchanged apart from its file location. Surfaced by clean-code-review (#3) and tidy-first-review.

The retention task ages baseline rows out alongside the rest; only the live row is preserved unconditionally. The config comment said "baseline rows are never pruned" — wrong; corrected. * **Stale test reference** (``tests/integration_tests/dashboards/version_history_tests.py:21,155``) to ``SUPERSET_VERSION_HISTORY_MAX_VERSIONS`` (the count-based name from the design spike) — replaced with the live name ``_RETENTION_DAYS``. * **``models/slice.py:356`` ``# noqa: S704`` rationale** (committer-review v2). ``Slice.url`` interpolates only the integer primary key, so the URL has no user-controlled segment requiring ``escape()``. Added the why-it's-safe comment. * **Fourth use site for ``CONTINUUM_BOOKKEEPING_COLUMNS``** (tidy-first v2 #2). ``superset/versioning/queries.py:469`` still inlined the literal set; pointed at the constant. * **Typo "ofthe" in ``changes/state.py:33``** (python-review v2). * **Partial-index migration downgrade robustness** (sqlalchemy-review v2 S-1). ``op.drop_index(..., if_exists=True)`` so a downgrade after a partial-application upgrade doesn't raise on the indexes that never got created.

Each per-resource RestApi declares a module-level spec helper (_chart_restore_spec, _dashboard_restore_spec, _dataset_restore_spec) that the endpoint method passes through. Endpoint signature drops from 9 to 5 call-time parameters. Per-resource inline imports of the restore command stay inside the helper, preserving the bootstrap-order properties of the versioning init path.

Under sustained write pressure on a heavily-edited deployment, the prune can fail to make progress for many days in a row with only a single log line per attempt. Add a bounded inline retry inside ``_prune_old_versions_impl``: * The SERIALIZABLE block is extracted to ``_run_prune_pass`` so each attempt opens a fresh connection + transaction from a clean snapshot (the previous one is implicitly rolled back when the context manager exits via exception). * Up to ``_MAX_RETRY_ATTEMPTS`` = 3 attempts, with exponential backoff at ``_RETRY_BACKOFF_BASE_SECONDS`` = 0.1s (0.1s → 0.4s for a total ~0.5s extra latency in the worst case). * On exhaustion the underlying ``OperationalError`` re-raises so the Celery wrapper's existing handler logs and returns ``{"error": 1}`` — the inline retry shrinks the recovery window for transient conflicts; it does not replace the outer safety net. * When at least one retry was needed the stats dict carries ``"retried": `` for observability. Two integration tests cover the new behavior end-to-end against the existing dashboard fixture: one verifies the retry-then-succeed path and that ``stats["retried"] == 1``; the other verifies the give-up path raises after exactly ``_MAX_RETRY_ATTEMPTS``. ``time.sleep`` is patched in both so the tests run in the same wall-clock budget as the existing retention test.

Split into named helpers so the top-level reads as a sentence: * ``_real_dirty_versioned_children(session, child_map)`` — generator yielding child instances that are real edits (filters phantom-dirty entries from lazy-load side effects / audit auto-bumps). * ``_resolve_parent(child, child_map)`` — registry lookup with the "is the parent attribute loaded and the expected class?" guard. * ``_flag_parent(parent)`` — picks the deterministic non-excluded column (description > uuid > col_keys[0]), ``flag_modified``s it, returns ``False`` on the fresh-session.new-instance case. The top-level loop now reads as: for child in _real_dirty_versioned_children(session, child_map): parent = _resolve_parent(child, child_map) if parent is None or parent in new_set: continue if _flag_parent(parent): pin_audit_columns(parent) Behaviour preserved exactly. The mid-function comment blocks that previously explained the next three lines migrate to the docstrings of the helpers — code-as-documentation instead of comment-as- documentation. Also fixes a stale patch target in ``test_pin_audit_columns_tolerates_ invalid_request_error``: the test was patching ``superset.versioning.baseline.attributes.flag_modified``, but ``attributes`` is imported inside ``dirty.py``; the correct target is ``superset.versioning.baseline.dirty.attributes.flag_modified``. The test was passing previously because the broken patch silently no-op'd on the side-effect path; under the extraction the lookup-resolution ordering surfaced the error.

The bare ``model_cls: type`` signature accepted ``type[int]`` and any other class; type-checking caught nothing at the call sites. Tighten to ``model_cls: type[Model]`` across the versioning helpers: ``queries.py`` (10 signatures), ``restore.py`` (1), ``api_helpers.py`` (4), ``changes/state.py`` (2). ``etag.py`` already used the tightened form; the rest now match.

That code path was unexercised, and the CD review v4 flagged that absence as load- bearing: an operator hitting the rollback in anger is a worse place to find a downgrade bug than CI. New test file ``versioning_round_trip__tests.py`` matches the existing ``composite_pk_round_trip__tests.py`` pattern (in-memory SQLite + Alembic ``MigrationContext``) and walks three scenarios: * **Populated round-trip** — upgrade both migrations, insert rows into all 8 versioning tables (live + closed shadow rows, both parent and child, with field-level ``version_changes`` records and M2M shadow rows), downgrade both migrations, assert every table is gone, then re-upgrade and assert the schema shape matches the first upgrade byte-for-byte (idempotency under round-trip). * **Empty downgrade** — sanity belt-and-braces that downgrade run immediately after upgrade (no rows) is also clean. Catches the case where the population step somehow influenced the drop path. * **Indexes-downgrade idempotency** — runs ``8f3a1b2c4d5e.downgrade`` twice in a row. The second call must be a no-op (the migration uses ``if_exists=True`` on every drop) so an operator who interrupts and re-runs doesn't hit a missing-index error. The MEDIUMTEXT cross-backend dimension is delegated to the CI matrix (SQLite collapses every text column to TEXT regardless of declared type); the shape pinned here is reversibility under load.

Run ``8f3a1b2c4d5e.downgrade()`` then ``56cd24c07170.downgrade()``. +4. Assert every created table, index, and (where applicable) sequence + is gone.

The retention task lives in its own beat entry and runs against existing shadow data regardless of capture; the warn-log was previously bypassed on exactly the deployment path (kill-switch flipped in anger) where the operator is most likely to also have a hand-rolled ``CeleryConfig`` with a missing prune entry. Move the call above the early-return so both misconfigurations surface at the same restart. * **`_warn_if_retention_beat_missing` handles dict-form and None `CELERY_CONFIG`** (python W2 / sqlalchemy W1 / CD-2). The default shape is ``type[CeleryConfig] | None``, but Celery itself accepts a dict via ``config_from_object``, and ``None`` is the documented "disable Celery entirely" path. The prior ``getattr(_, "beat_schedule", None) if _ else None`` fell through to the WARNING in both cases, emitting a false positive for operators who chose either shape on purpose. Discriminate by ``isinstance(dict)`` and short-circuit on ``None``. Also extract the retention task name to a class-level ``_RETENTION_TASK_NAME`` constant so the previous 90-char line shortens and the literal is no longer duplicated against the default in ``config.py``. * **`ENABLE_VERSIONING_CAPTURE` env-var-to-bool uses ``utils.parse_boolean_string``** (python W1). The hand-rolled ``.lower() == "true"`` only matched the literal ``"true"``; operators setting ``1``, ``yes``, ``on``, ``True`` (no .lower call) silently got ``False`` (capture on — the safe direction for a default-on kill-switch, but surprising and inconsistent with the rest of ``config.py`` which uses the helper). * **`from __future__ import annotations` in `versioning/factory.py`** (python W4). Every other versioning module has it; this was the lone outlier. PEP 604 union syntax in a local-variable annotation worked without it on Python 3.10+, so this is consistency, not correctness. * **Drop the dead `last_exc` / unreachable `RuntimeError`** in ``_prune_old_versions_impl`` (tidy-first dead-code finding). The retry loop always returns or re-raises; the post-loop fallback was defensive code for a control-flow path the loop's exit condition cannot reach. Replaced with a short ``AssertionError`` that mypy needs for type-narrowing and that documents the invariant (post-loop = "the loop's exit condition was changed incorrectly").

Add ten focused unit tests: **`tests/unit_tests/initialization_test.py::TestInitVersioning`** — six tests covering the kill-switch flow and the four ``CELERY_CONFIG`` shapes the warn-log helper now discriminates: * ``test_kill_switch_off_skips_listener_registration`` — pins the contract that ``ENABLE_VERSIONING_CAPTURE=False`` short-circuits ``init_versioning`` before either listener registers. * ``test_warn_when_celery_beat_schedule_missing_retention_entry`` — class-shaped config with the entry absent fires WARNING. * ``test_no_warn_when_celery_beat_schedule_includes_retention_entry`` — class with the entry present is silent. * ``test_no_warn_when_celery_config_is_none`` — Celery-disabled deployment doesn't see the false-positive that motivated the v5 ``isinstance / None`` guard. * ``test_dict_form_celery_config_with_entry_does_not_warn`` — Celery's documented dict-shape works. * ``test_dict_form_celery_config_without_entry_warns`` — and the dict-shape symmetry holds when the entry is missing. **`tests/unit_tests/tasks/test_version_history_retention.py`** — four tests pinning the statsd-emission contract on every branch: * ``test_retention_disabled_emits_skipped_metric`` — ``retention_days=0`` fires ``.skipped``. * ``test_no_versioned_classes_resolved_emits_skipped_metric`` — the init-order-regression branch also fires ``.skipped`` (same metric on purpose; dashboard alert is "no work happening", WARNING log carries the why). * ``test_serialization_failure_then_success_increments_retried_once`` — one ``OperationalError`` on attempt 1 fires ``.retried`` exactly once, succeeds on attempt 2, records ``retried=1`` in the stats dict, emits the ``.pruned_transactions`` gauge. * ``test_all_attempts_fail_reraises_after_max_retries`` — exhausted retries fire ``.retried`` exactly ``_MAX_RETRY_ATTEMPTS`` times and re-raise so the outer Celery wrapper catches. Total: 10 new tests, all passing in <1s wall-clock. Closes the v5 CD + clean-code finding ("the operational instrumentation that just shipped isn't itself pipeline-gated by tests"). A future refactor that restructures ``init_versioning`` or renames a metric now has to deliberately update these tests rather than silently breaking the contract.

The path[0]-encoded verb is dropped in favour of the explicit operation column populated by sc-103156's change-record listener. Pure-helper unit tests cover per-kind row selection, change folding, and the activity-payload assembly. constants.py adds the list_activity route-method permission so the REST endpoints flow through the standard FAB check.

Authorisation reuses the resource's existing can_read permission. Two batched-query paths eliminate N+1 on dashboard scope: impact-count collapses many per-chart counts into one query keyed by version_uuid, and _datasets_used_by_chart batches lookups across the dashboard's chart set rather than iterating. Perf-validation harness extended with seeded fixtures and ordering assertions; activity-view integration tests cover the round-trip plus the cross-coupling check (T050) that prevents activity-view from accidentally pulling restore-scope rows.

The dropdowns were scaffolded as the temp commit on sc-103156 (no field consumption yet); this commit fills in the proper rendering against the activity-view API shape.

Four independent reviewers (amin, superset-committer, python, clean-code) flagged the same issue on the new ``/activity/`` endpoint family. constants.py — ``MODEL_API_RW_METHOD_PERMISSION_MAP["activity"]`` changed from ``"write"`` to ``"read"``. GET /activity/ now flows through ``can_read`` on the resource class, matching REST convention and the per-resource gate documented in ``SECURITY.md``. versioning/activity.py — ``resolve_endpoint_path_entity`` dispatches ``security_manager.raise_for_access`` by model class via the ``_RAISE_FOR_ACCESS_KWARG`` mapping (Slice → ``chart=``, Dashboard → ``dashboard=``, SqlaTable → ``datasource=``). Same object-level gate the ``/versions/`` GETs already use after M2. Test docstrings in ``activity_view_tests.py`` updated to reflect the new gate; assertions unchanged because the test infrastructure configures Alpha without datasource access on the admin fixture, so ``raise_for_access`` rejects via the same path ``raise_for_ownership`` did.

Both flagged by clean-code-review as duplication; the activity-view's exception-raise pattern is the cleaner of the two. Move ``PathEntityResponseError`` + ``_RAISE_FOR_ACCESS_KWARG`` + ``resolve_endpoint_path_entity`` into ``api_helpers.py`` and rewrite ``list_versions_endpoint`` / ``get_version_endpoint`` to call it. The ``access_kwarg`` parameter goes away — the dispatch table derives it from ``model_cls.__name__``. Per-resource API methods become ``return list_versions_endpoint(self, Slice, uuid_str)``. ``activity.py`` re-exports the two names at the top of the module so ``charts/api.py`` / ``dashboards/api.py`` / ``datasets/api.py`` callers that already use ``activity_module.PathEntityResponseError`` don't need an import-path migration.

On dashboard-scope activity responses with 50+ related entities the loop dominated latency. Replace the per-entity loop with each resource's existing SQL-side access filter: * ``DashboardAccessFilter`` — owners, published+datasource-access, RBAC roles, embedded tokens * ``ChartFilter`` — owners, dataset access, dashboards * ``DatasourceFilter`` — datasource permissions These are the same filters FAB applies via ``base_filters`` on the list endpoints of each resource's ``ModelRestApi``, so activity-view visibility matches the rest of the read surface byte-for-byte. Two SQL queries per kind (one for live ids, one for the access- filtered subset) replace the N permission-graph traversals. Live-row absence is now detected via set difference rather than a Python ``None`` check. The ``_can_read`` dispatch helper is removed (no callers). Three unit tests targeting it in ``test_activity.py`` are deleted — integration tests in ``activity_view_tests.py`` exercise the visibility behavior at the right level (``test_activity_denies_non_owner`` and the chart equivalent).

Split along those existing boundaries into seven submodules: * ``activity/kinds.py`` (~120 LOC) — kind translation tables, ``Window`` / ``EntityWindows`` type aliases, ``_NOT_FOUND_EXC`` per-kind exception mapping, ``_NAME_COLUMN`` shadow-column lookup, and ``_load_shadow_model`` shadow-class loader. * ``activity/scope.py`` (~190 LOC) — pure window arithmetic (``_intersect_windows`` / ``_union_windows`` / ``_row_within_any_window``) and scope resolution (``_resolve_scope`` / ``_resolve_{dashboard,chart,related}_scope`` / ``_merge_entity_windows``). * ``activity/queries.py`` (~430 LOC) — every DB-touching helper: ``_resolve_path_entity``, Phase A relationship walks (``_charts_attached_to_dashboard`` / ``_datasets_used_by_chart`` / ``_batch_datasets_used_by_charts``), Phase B change-record fetch (``_fetch_change_records`` / ``_select_change_rows_for_kinds``), name denormalization (``_resolve_names_for_kind`` / ``_denormalize_entity_names``), and tombstone state (``_check_entity_tombstones``). * ``activity/impact.py`` (~160 LOC) — per-record impact-count (``_collect_impact_pairs`` / ``_batch_chart_counts`` / ``_impact_for_record``). * ``activity/visibility.py`` (~165 LOC) — the AV-008 silent visibility filter (``_filter_records_by_visibility`` / ``_resolve_visibility``). * ``activity/render.py`` (~210 LOC) — record decoration (``_decorate_records`` / ``_lookup_entity_uuids`` / ``_build_summary`` / ``_changed_by_dict`` / ``_SUMMARY_VERBS``). * ``activity/orchestrator.py`` (~280 LOC) — public ``get_activity``, ``parse_activity_query_params`` + the per-param parsers, ``ActivityParamsError``, plus the T037/T038 observability instrumentation (``_phase_timer`` / ``_emit_request_shape_attributes`` / ``_METRIC_PREFIX``). ``activity/__init__.py`` re-exports 47 symbols — every name imported across package boundaries (public API + test-private names tested by ``test_activity.py`` + the ``activity_module.``-style attribute access used by the three ``/activity/`` endpoint callers). External callers don't need import-path changes. ``PathEntityResponseError`` and ``resolve_endpoint_path_entity`` are re-exported from :mod:`superset.versioning.api_helpers` (where they live alongside the ``/versions/`` endpoint handlers) so the ``activity_module.``-style call sites in ``charts/api.py`` / ``dashboards/api.py`` / ``datasets/api.py`` keep working. Smoke-tested in the running container: all 47 re-exported names import cleanly via ``from superset.versioning.activity import ...``. Surfaced by clean-code-review (#3) and tidy-first-review.

From 5bcf2d6c4e7dd1497a73e1cb837941d2ae6e13f1 Mon Sep 17 00:00:00 2001 From: Mike Bridge Date: Wed, 3 Jun 2026 11:40:42 -0600 Subject: [PATCH 078/114] refactor(activity-view): v2 review easy fixes (PEP 604 + doc-notes) Three v2 review items, all NIT/Suggestion tier, batched together because each is a one- or two-line touch: * **PEP 604 / 585 modernization** of the ``activity/`` package (python-review W-PR2-1, amin NIT). The prior modernization commit ``95592ad4fa`` ran before ``activity.py`` was split into a package; the new submodules carried the old ``typing.Optional[...]`` form forward. ``ruff check --select UP006,UP007,UP035 --fix`` resolves 20 sites across ``kinds.py``, ``scope.py``, ``queries.py``, ``orchestrator.py``, ``render.py``, ``impact.py``, plus ``tests/unit_tests/versioning/test_activity.py:33,88``. Pre-commit cleaned up the now-unused ``Optional`` imports. * **Inline-imports doc-note** in ``activity/visibility.py`` (python-review W-PR2-3). Mirrors the precedent set by ``superset.versioning.baseline`` and replicated in ``activity/queries.py`` / ``changes/shadow_queries.py``. The FAB-filter imports must defer until call time because ``init_versioning()`` runs before all model mappers are configured. * **Init-order dependency comment** on ``_select_change_rows_for_kinds`` (sqlalchemy-review W-3). ``tx_tbl.c.action_kind`` resolves only after ``VersionTransactionFactory`` has appended the column at app start; locks down the dependency for future refactors that might call the helper outside the request path.

From 05d198a9eab6067526d75585b4ac8ecf335959ea Mon Sep 17 00:00:00 2001 From: Mike Bridge Date: Wed, 3 Jun 2026 11:51:11 -0600 Subject: [PATCH 081/114] refactor(activity-view): split scope.py windows out into windows.py MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ``activity/scope.py`` mixed pure interval arithmetic (``_intersect_windows`` / ``_union_windows`` / ``_merge_entity_windows`` / ``_row_within_any_window``) with DB-touching scope resolution (``_resolve_dashboard_scope`` / ``_resolve_chart_scope``). The pure functions were called by ``activity/queries._fetch_change_records`` via a lazy import to dodge a ``scope ↔ queries`` cycle. Pull the four pure functions into ``activity/windows.py``: * ``scope.py`` keeps the four DB-touching resolvers and imports the pure helpers from ``windows.py``. * ``queries.py`` now imports ``_row_within_any_window`` from ``windows.py`` at module-top; the lazy import inside ``_fetch_change_records`` is dropped. * ``windows.py`` depends only on ``kinds.py`` for the ``Window`` / ``EntityWindows`` type aliases. Clean dependency tree: kinds → windows → scope → queries ``__init__.py`` re-exports preserve the existing test imports. Smoke-tested inside the container: the same function object is reachable via ``superset.versioning.activity._intersect_windows`` and via ``superset.versioning.activity.windows._intersect_windows``. Surfaced by clean-code-review v2 (G6).

As a tuple alias it: * carried no constructor invariant (a window with ``end_tx <= start_tx`` was syntactically valid), * exposed no methods, so the half-open ``contains`` predicate was re-implemented inline at every caller (``start <= tx_id and (end is None or tx_id < end)``), * was nominally indistinguishable from any other ``tuple[int, int]`` — a function accepting one could be called with a Unix-timestamp pair and would type-check. Promote to ``@dataclass(frozen=True)`` with ``start_tx`` / ``end_tx`` fields, a ``__post_init__`` invariant check, and ``contains`` / ``intersect`` / ``merges_with`` methods. The closure-of-operations property (every operation on a ``Window`` returns a ``Window`` or a derived value) now lives on the type itself. ``_intersect_windows`` becomes a thin wrapper over ``Window.intersect`` (kept so callers and tests don't have to migrate to method form in lockstep). ``_row_within_any_window`` reads ``w.contains(tx_id)``. ``_union_windows`` reads ``w.start_tx`` / ``w.end_tx`` instead of ``w[0]`` / ``w[1]``. ``queries.py`` and ``scope.py`` construct ``Window(start, end)`` instead of bare tuples. Tests updated to construct ``Window(10, 20)`` instead of ``(10, 20)`` — equality semantics are preserved (frozen dataclasses are equal-by-attribute). ``EntityWindows = tuple[str, int, list[Window]]`` is left as a tuple alias for now; promoting it is a separate question (the ``(api_kind, entity_id)`` pair is logically a key with the window list as its value, so a registry / Map shape may be a better fit than a flat dataclass). DDD lens — this is the Value Object pattern (Blue Book Ch. 5): identity by attributes, immutable, side-effect-free, closed under operations. The pre-state was the Anemic Value Object anti-pattern.

The three resource families wired today cover every key, but a future entity added to the versioning surface without updating this table should fail closed (named exception, test catches it) rather than leak the unknown class name into a generic 500 via the unhandled KeyError text. * A2 — Visibility module's docstring names the FAB-filter relationship as a **Conformist** integration (Evans, Blue Book Ch. 14): we consume ``DashboardAccessFilter`` / ``ChartFilter`` / ``DatasourceFilter`` directly rather than translating them through an Anti-Corruption Layer. List endpoints and activity-view stay consistent at the cost of coupling to FAB's exact filter shape. Future entities added to the activity surface must extend the dispatch table in ``_resolve_visibility``. * S1 consumer — ``schemas.ACTIVITY_ACTION_KINDS`` now derives from ``superset.versioning.changes.ACTION_KINDS`` (the Published Language constant added in the parent commit). A future addition (e.g. ``"thumbnail_warm"``) updates one constant; the schema picks it up automatically.

A dashboard with N attached charts can reach the floor with chart-history fan-out. * W4 — ``_lookup_entity_uuids`` (render.py) and ``_check_entity_tombstones`` (queries.py) wrap their batch ``session.connection().execute()`` calls in ``db.session.no_autoflush``. Today's request-path callers have no pending writes; the guard matches the defensive posture of the listener-side reads and is zero-cost in the no-pending-writes case. * W2 — ``_resolve_visibility`` now fails closed for any kind that is in the change-records taxonomy (``_NAME_COLUMN``) but missing from the access-filter dispatch (``access_filter_classes``) — a future entity added without wiring its access filter would have silently disclosed every change record for that kind.

Effect: on any multi-kind call (every dashboard activity request with `include=all`), only the last-iterated kind's `rows`/`entity_ids`/`api_kind`/`has_deleted_at` got processed; earlier kinds had their SELECT fire and the rows discarded. Downstream consequence at `render.apply_record_decoration:117-119`: the missing-key fallback `tombstones.get(..., {"deleted": True})` defaults non-last-kind records to tombstoned, so live charts on a dashboard get rendered as hard-deleted (`entity_deleted: true`, `entity_uuid: null`) whenever the SqlaTable kind happens to iterate after Slice (and vice versa for live datasets when Slice iterates last). Order-dependent on dict iteration; not caught by the single-kind tombstone test which the previous integration coverage relied on. Fix is a 4-line re-indent into the per-kind loop body, restoring the pre-`8dd112f8cf` shape. New integration test `test_check_entity_tombstones_handles_multiple_kinds` calls the helper directly with a `{("Slice", id), ("SqlaTable", id)}` set and asserts both keys land in the result dict with the correct `deleted=False` shape. Identified by four of eight v4 reviewers independently (sqlalchemy / python / clean-code / tidy-first).
