⚠️ KNOWN ISSUE: This version can cause severe page load slowdowns (multiple seconds per page) on some production databases due to an unpredictable MySQL query execution plan on the prev_posts COUNT query. Please upgrade directly to v1.1.3 or later.
phpBB SEO Framework Lite 1.1.2
Fixed & Improved
- Link-Rewriting Performance & N+1 Query Elimination:
- Added zero-query fast-paths in
SlugRepository for topic first posts (prev_posts = 0) and last posts (topic_posts_approved - 1), completely eliminating repetitive COUNT(prev_posts) queries.
- Implemented batch post position pre-seeding across
onViewForumTopics and onDisplayForums, cutting page generation queries by up to 65% and reducing link rewriting overhead to 0.015ms per link with 0 additional queries during template rendering.
- Canonical Pagination & Deep Links:
- Fixed silent pagination offset loss on native phpBB topic URLs containing entity-encoded parameters (
viewtopic.php?t=X&start=Y and &start=Y), properly preserving target pages during 301 redirects.
- Fixed direct post URLs (
viewtopic.php?p=...) to accurately resolve to multi-page canonical targets (/topic/slug-ID/page/X/#p...) based on approved post positions.
- Added fail-closed handling for non-existent post IDs, safely returning HTTP 404 instead of malformed
-0/ URLs.
- Cleanly stripped encoded routing parameters from redirect targets while preserving marketing/tracking parameters (
utm_*, gclid).
- Automated XML Sitemap Invalidation:
- Automatically invalidates sitemap statistics and boundary caches upon new topic creation, topic deletion, and moderation approvals.
- Added event subscriptions for
core.approve_topics_after and core.approve_posts_after to persist topic slugs and refresh sitemap caches when queued topics are approved.
- Enhanced boundary map cache purging across standard chunk sizes (500 to 50,000) and custom configured values.
- Maintained zero database queries on the hot path during cache invalidation.
