Changeset 659 for trunk/admin/update.php


Ignore:

Message:
  • admin/update : filesystem synchronization process completely rewritten. How to speed up sync ? by avoiding recursivity !
  • admin/update : option to display verbose information details
  • admin/update : option to simulate only. No database insert, delete or update will be made
  • bug fixed : in admin/cat_list, if you delete a virtual category, you may create a gap in the rank list. This gap will generate errors when trying to move a category on this gap. Fixed by calling ordering and update_global_rank at category deletion.
  • admin/cat_list, only one query to insert a new virtual category (no need of a second query to update uppercats and global_rank)
  • for a given category, even if empty, the representing element must not be the one of a forbidden category for the current user
  • generation time optionnaly displayed on the bottom of each page becomes more price : number of SQL queries and SQL time added.
