Staging remediation log: Page Forms fatal after SMW 5.1.0 upgrade

Date: 2026-06-10

Environment: staging only (dev.weaponofmusicaldefense.com)

Summary

After upgrading Semantic MediaWiki (SMW) on staging to 5.1.0, Special:FormEdit/Web_citation began failing with HTTP 500 and a fatal exception. The failure was due to Page Forms calling SMW legacy class aliases removed in SMW 5. A targeted compatibility patch was applied in staging, and the endpoint now renders successfully (HTTP 200).

Problem observed

• Failing URL:
  • https://dev.weaponofmusicaldefense.com/thelibrary/Special:FormEdit/Web_citation
• Symptom:
  • Fatal exception / HTTP 500 on staging.
• Root error identified:
  • Class "SMWDIProperty" not found

Root cause

SMW 5 removed long-deprecated global class aliases (including SMWDIProperty and related legacy names). The installed Page Forms branch still used legacy class names in multiple files, causing runtime failures in FormEdit-related code paths.

Changes applied

1) Page Forms: namespaced SMW class updates

Updated Page Forms calls from legacy aliases to namespaced SMW classes in:

• mw_data_staging/extensions/PageForms/includes/PF_TemplateField.php
• mw_data_staging/extensions/PageForms/includes/PF_ValuesUtils.php
• mw_data_staging/extensions/PageForms/specials/PF_CreateTemplate.php

Representative edits:

• SMWDIProperty::newFromUserLabel(...) → \SMW\DIProperty::newFromUserLabel(...)
• SMWDIWikiPage::newFromTitle(...) → \SMW\DIWikiPage::newFromTitle(...)
• new SMWRequestOptions() → new \SMW\RequestOptions()
• new SMWConceptDescription(...) → new \SMW\Query\Language\ConceptDescription(...)
• new SMWPrintRequest(...) → new \SMW\Query\PrintRequest(...)

2) Page Forms: safe adjustment for DataValueFactory method availability

In PF_TemplateField.php, the label-format code path previously called SMWDataValueFactory::findTypeID(...). That method is not available in the installed SMW runtime. The staging patch now uses $this->mPropertyType directly as the type ID before calling:

• \SMW\DataValueFactory::newTypeIDValue(...)

3) Debug exposure cleanup

After validation, staging exception-detail output was disabled again:

• mw_data_staging/LocalSettings.php
• Confirmed value:
  • $wgShowExceptionDetails = false;

Validation performed

Endpoint check

• Requested:
  • https://dev.weaponofmusicaldefense.com/thelibrary/Special:FormEdit/Web_citation
• Result:
  • HTTP 200
  • Response contains Create Web citation heading/title
  • No fatal exception text in response

Log check

• Searched staging container logs for:
  • SMWDIProperty
  • Call to undefined method
  • Fatal exception / PHP Fatal
• Result:
  • No new fatal matches after patch/validation requests

Current status

• Staging FormEdit path is restored for Web_citation.
• Staging remains on:
  • MediaWiki 1.41.1
  • Semantic MediaWiki 5.1.0
• This removes the immediate blocker introduced by the SMW upgrade and clears the path for subsequent staged core/runtime upgrade work.

Notes

• Changes were intentionally limited to staging files under mw_data_staging.
• No production routing/content changes were made in this remediation.
