revert: undo wu_pre_* filter chokepoints (ADR-001 Amendment 1 supersedure) by superdav42 · Pull Request #1262 · Ultimate-Multisite/ultimate-multisite

superdav42 · 2026-05-22T17:21:14Z

Summary

Reverts two recently-merged PRs that added wu_pre_* filter chokepoints to the model layer. These filters were the load-bearing interception points for the original WP Ultimo Multi-Tenancy Phase 3.4/3.5 plan (a REST-pull Network_Client SDK on each sovereign tenant).

That plan has been superseded by ADR-001 Amendment 1 — Direct-DB Push Model (merged downstream in Ultimate-Multisite/ultimate-multisite-multi-tenancy#86). Under the new architecture:

The sovereign tenant runs as a near-stock single-site WordPress install.
The tenant never calls out to the network at request time — no HTTP client, no JWT, no cache layer.
Network state changes are pushed into each tenant's local wp_options / wp_blogmeta by a network-side Tenant_State_Pusher (Action Scheduler job).
The tenant reads only from its own local DB.

The two wu_pre_* filter PRs being reverted have no consumer under the push model and become dead-code surface in core. Removing them keeps upstream's API minimal.

Reverted PRs

Reverted	Original PR	Description	Reason
commit `00d617fc`	`#1260`	`wu_pre_*` filters on 6 model methods	Tenant never hooks these under push model
commit `9acf0c7f`	`#1259`	`wu_pre_*` filters on `Base_Model::get_by_id`, `::get_by`, `::get_by_hash`	Tenant never hooks these under push model

Kept (aligned with amendment, not reverted)

PR	Description	Why kept
`#1257`	Disable tenant-side Gateway Manager in sovereign mode	Aligned — sovereign tenant has no payment surface
`#1258`	Disable incompatible compat shims in sovereign mode	Aligned — incompatible behaviour gated off
`#1261`	Disable tenant-side Checkout in sovereign mode	Aligned — customer-facing checkout moves to main site

These three will be extended in a follow-up PR (downstream "3-A7") to disable the remaining customer-facing UI elements (Account_Summary, Billing_Info, Invoices, My_Sites, Subscription, Site_Actions, Template_Switching, Domain_Mapping) in sovereign mode, with replacement links to a new main-site Customer_Hub (downstream "3-A8").

Risk

Low. The reverted filters are net-new in core (merged hours ago) and have no published consumer. Reverting before any third-party integration depends on them is the cheap moment.

Verification

git diff origin/main -- inc/models/class-base-model.php — clean removal of the filter blocks
git diff origin/main -- inc/models/*.php — clean removal of per-method filter blocks
Core test suite unchanged; these PRs introduced no test coverage that needs accompanying removal.

Summary by CodeRabbit

Refactor
- Removed internal filter hooks across multiple models (Base_Model, Customer, Domain, Membership, and Site) that previously allowed early result overrides. Methods now execute their standard database logic directly.
- Removed corresponding tests for filter behavior.

Note: If you've customized integrations using these filter hooks, they will require updates.

This reverts commit ef74b6a. Under ADR-001 Amendment 1 — Direct-DB Push Model (Ultimate-Multisite/ultimate-multisite-multi-tenancy#86), sovereign tenants do not read network state via filter chokepoints at request time. Instead, the network pushes state into each tenant's local wp_options / wp_blogmeta via a Tenant_State_Pusher Action Scheduler job, and the tenant reads only from its local DB. These wu_pre_* filters on Base_Model::get_by, ::get_by_hash, ::query_by_columns, and the upstream model methods were the load-bearing interception points for the original REST-pull plan (Phase 3.4 / Phase 3.5). Under the push model they are dead-code surface — no sovereign tenant code hooks them. Reverting to keep core's surface area minimal. Ref Ultimate-Multisite/ultimate-multisite-multi-tenancy#86

)" This reverts commit f87f1e2. Under ADR-001 Amendment 1 — Direct-DB Push Model (Ultimate-Multisite/ultimate-multisite-multi-tenancy#86), the sovereign tenant runs as a single-site WordPress install that reads only its local DB. The Base_Model getter filters (get_by_id, get_by, get_by_hash) were intended as the interception points for the tenant's planned Network_Client SDK, allowing the tenant to service model reads from network state. That entire plan is replaced by direct-DB push from network into the tenant's local wp_options / wp_blogmeta. The tenant has no SDK, no HTTP client, no cache, no filter hook into Base_Model. These filters become dead-code surface in core and are reverted to keep the upstream API minimal. The companion 6-model-method filters PR (#1260) is reverted in the preceding commit.

📝 Walkthrough

Walkthrough

Removes apply_filters() early-return hooks from Base_Model static lookup methods and six model-specific query/aggregate methods, eliminating filter-based overrides that previously allowed plugins to short-circuit database execution. Corresponding test coverage is removed.

Changes

Model filter hook removal

Layer / File(s)	Summary
Base_Model lookup filters `inc/models/class-base-model.php`	`get_by_id()`, `get_by_hash()`, and `get_by()` remove `wu_pre_get_by_id_{$model}`, `wu_pre_get_by_hash_{$model}`, and `wu_pre_get_by_{$model}` early-return filters, proceeding directly to query class instantiation without filter-based short-circuiting.
Model-specific aggregate and lookup filters `inc/models/class-customer.php`, `inc/models/class-membership.php`, `inc/models/class-domain.php`, `inc/models/class-site.php`	`Customer::get_total_grossed()`, `Membership::get_total_grossed()`, `Domain::get_by_site()`, `Site::get_membership()`, `Site::get_all_by_type()`, and `Site::get_all_categories()` remove their respective `wu_pre_*` early-return filter hooks, executing database queries directly without override capability.
Test coverage removal `tests/WP_Ultimo/Models/Base_Model_Test.php`	Seven test methods validating pre-filter behavior are removed, including tests for null defaults, instance returns, and model discrimination by the `wu_pre_get_by_*` filter family.

Poem

🐰 The filters fade like morning dew,
Those pre-get hooks we bid adieu,
Direct to queries, swift and clean—
No overrides to intervene!
Tests retire as hooks depart,
A simpler model-layer art. 🌱
