Consistency: Harden input validation, query preparation, and caching

[timse201]

Harden input validation, query preparation, and caching in Consistency route.

• Ensure search and set parameters are valid strings before use.
• Verify that the locale and project exist before accessing their properties.
• Validate locales against GP_Locales::exists() and filter out translation sets with two or more slashes.
• Bump the translation sets cache key to translation-sets-v2.
• Refactor query() to use a single, standard $wpdb->prepare() call.
• Separate translation, context, and project path comparisons in _sort_callback() to prevent false matches and casting warnings.
• Group search results by translation and cache project lookups to reduce template rendering overhead.
• Remove redundant hardcoded locale exclusions from the template.
• Escape project and source links with esc_url().
• Improve table markup semantics and update toggle button text between "View" and "Hide".

Summary by CodeRabbit

• Bug Fixes
  • Search handles malformed locale data and validates search inputs and translation sets more reliably.
  • Project filters apply only when the selected project has a valid path.
  • Search results include duplicate rows in their counts and are sorted consistently by translation and context.
  • Translation-set listings exclude sets with unknown locales or malformed names.
• Improvements
  • Translation navigation arrows appear independently when previous or next translations are available.
  • The results toggle label reflects whether the list is shown or hidden.

📝 Walkthrough

📝 Walkthrough

Walkthrough

The consistency route validates search, translation-set, and project values. It filters translation sets, binds query parameters, and sorts results by translation and context. The template groups results by translation, caches project metadata, and updates navigation and visibility controls.

Changes

Consistency Search

Layer / File(s)	Summary
Validate search inputs and translation sets wordpress.org/public_html/wp-content/plugins/wporg-gp-routes/inc/routes/class-consistency.php, wordpress.org/public_html/wp-content/plugins/wporg-gp-customizations/templates/consistency.php	The route validates search values and filters translation sets by locale and key format. The template updates its locale exclusions and combines options using array union.
Build and order search results wordpress.org/public_html/wp-content/plugins/wporg-gp-routes/inc/routes/class-consistency.php	The query binds search values and adds a project-path filter only when a project has a path. Sorting compares translation, context, and project path separately.
Group and render consistency results wordpress.org/public_html/wp-content/plugins/wporg-gp-customizations/templates/consistency.php	The template groups results by translation, caches project hierarchy details, builds escaped project and source URLs, and updates navigation arrows and the visibility toggle label.

Merge Risk: ⚪ Minimal · up to 1bd40

The reviewed search options and result navigation preserve their intended behavior. No actionable merge-blocking risk remains after normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to c54a8

The public search becomes more restrictive in normal operation, and no new security exposure was established. Previously cached set lists can delay the new filtering until they expire, so the rollout behavior is not fully assured.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The affected exposure is the existing public consistency-search route and its translation read query, not a newly registered endpoint or a demonstrated new privilege boundary.

Trust Boundaries and Controls

• inferred — A legacy cached list could keep an otherwise excluded set selectable during rollout, but that selection was already possible before this PR. The downstream query still restricts returned records to active projects and active/current translations and originals.

Hardening Proposals

• proposed — If the new set filter must take effect immediately on deployment, invalidate or version the shared set-list cache key rather than relying on expiry.

Thanks! Some of these are real fixes:

• The is_string guards (an array search/project fatals in trunk).
• The GP_Locales::by_slug() null guard.
• explode( …, 2 ).
• The single prepare() call.
• Sorting by translation, then context, then path (concatenating the two mis-sorted).

Needs changing

1. get_translation_sets(): please drop the new JOIN gp_projects … p.active = 1. The query already scans and groups the whole gp_translation_sets table, which is very large on translate.wordpress.org. The join adds a lookup per row, and it only changes the output if a locale/slug pair exists only in inactive projects. query() already filters inactive projects out of the results.
2. Stale cache. The template removes the */formal/default entries from $sets_to_hide and relies on the new slash-count filter, but the translation-sets cache key is unchanged (24h TTL). Until it expires, cached 3-part entries come back in the dropdown. Either bump the cache key (e.g. translation-sets-v2) or leave the template list alone.
3. Scope. A few changes don't do anything, so please drop them:
   • MIN(name): wpdb already removes ONLY_FULL_GROUP_BY from the SQL modes, so the old query didn't fail on MySQL or MariaDB.
   • array_map( 'strval' ): array_count_values() turns numeric strings back into int keys.
   • p.path = %s OR …: the root project has no originals, so including it changes nothing.

Optional

• The @return object on the query method should be @return array.
• sanitize_text_field() on set isn't needed, since the value is checked against the $sets allow-list afterwards.

1. dropped
2. moved it to v2
3. I dropped it. (Not now. But For MySQL 9.2 will change it. https://dev.mysql.com/doc/refman/8.4/en/group-by-handling.html) I was optimizing it too much :)

I also included your recommendations.

Thank you
