28 · Batch operations are de-duplicated across all recipes – identical inserted steps are silently dropped¶


Project	Drupal CMS (drupal_cms_installer)
Component	Installer
Category	Task
Priority	Minor
Status	Reported upstream as #3591483

Problem/Motivation¶

drupal_cms_installer_apply_recipes() drops every operation that is already in the batch ("Only do each recipe's batch operations once"). The comparison is made against all operations, including those of earlier recipes. Anyone adding operations (e.g. a localisation step after each recipe) must make them unique, otherwise they are silently skipped.

Proposed resolution¶

Compare per recipe, or document the behaviour.

Additional information¶
