[#3081] Derived the host with 'parse_url()' when building trusted host patterns.

[AlexSkrypnyk]

Closes #3081

Summary

settings.lagoon.php and settings.container.php build $settings['trusted_host_patterns'] from LAGOON_ROUTES and LOCALDEV_URL respectively, and previously derived the host by stripping only the URL scheme via str_replace(['https://', 'http://'], '', $url), so any path or port present in the value stayed in the pattern.

DrupalKernel::setupTrustedHosts() matches the request Host header alone - the path is never part of it and the port is stripped before matching - so a route value carrying a path produced a pattern that could never match, and requests to that route were rejected with a 400 "The provided host name is not valid for this server."

Changes

• Derived the host in both files with parse_url($url, PHP_URL_HOST) ?: parse_url('//' . $url, PHP_URL_HOST), then lowercased it with strtolower((string) $host).
• The '//' . $url fallback keeps a scheme-less value (common for LOCALDEV_URL) parsing as a host rather than as a path.
• The emptiness guard and the '^' . preg_quote($host, '/') . '$' pattern construction are unchanged.
• Updated tests/phpunit/Drupal/EnvironmentSettingsTest.php: the four expectations derived from the LAGOON_ROUTES fixture value https://example2/com change from ^example2\/com$ (a pattern no Host header can ever match) to ^example2$; all other expectations derive from plain hostnames and are unchanged.
• Added testEnvironmentLocalContainerSchemelessUrls and testEnvironmentLagoonSchemelessRoutes covering scheme-less values with ports and paths for both providers, asserting lowercase host-only patterns.
• Regenerated installer fixtures, propagating the same changes into the fixture copies under .vortex/installer/tests/Fixtures/.

Summary by CodeRabbit

• Bug Fixes
  • Improved trusted-host handling for container and Lagoon environments.
  • Hostnames are now parsed more reliably from URLs and normalized to lowercase.
  • Corrected trusted-host expectations for preview, development, testing, and production scenarios.

Walkthrough

Trusted host generation now uses parse_url() with scheme-less fallback parsing and lowercase normalization in container and Lagoon settings. Tests now expect host-only patterns when route values contain paths.

Changes

Trusted host generation

Layer / File(s)	Summary
Parse trusted host URLs web/sites/default/includes/providers/settings.container.php, web/sites/default/includes/providers/settings.lagoon.php	Both providers extract hostnames with parse_url(), support scheme-less values, and lowercase the results.
Update trusted host expectations tests/phpunit/Drupal/EnvironmentSettingsTest.php	Preview, development, test, and production scenarios now expect ^example2$.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to a329f

Trusted-host patterns now correctly use lowercase hostnames without paths or ports, including support for scheme-less URLs. The change is low risk, but scheme-less URL cases should be covered by regression tests before relying on that behavior broadly.

Poem

A rabbit parsed each route with care
And found the host hiding there
Schemes fell away, paths stayed behind
Lowercase hosts aligned
Four tests now match the trail

Explanation

The reviewable code derives lowercase hostnames with parse_url(), supports scheme-less values with the // fallback, and updates the affected test expectations. Installer fixture updates cannot be verified because the relevant fixture files were excluded by the !.vortex/installer/tests/Fixtures/** path filter.
