INFORMATION_SCHEMA.INNODB_TABLESPACES_ENCRYPTION.NAME is NULL for undo tablespaces

Details

    Description

      marko encountered that few test cases in encryption and mariabackup suite are hanging
      when innodb_undo_tablespaces > 0 (MDEV-29986). Test cases in encryption suites are

       encrypt_and_grep
      		 
       debug_key_management
      		 
       innodb-remove-encryption
      		 
       innodb-spatial-index
      		 
       innodb-encrypt-freed
      		 
       innodb_encrypt_key_rotation_age
      		 
       innodb_first_page

      InnoDB:

       encryption_threads_shutdown

      Mariabackup:

       mdev-14447
      		 
       skip_innodb
      		 
       xb_partition

      Thanks to marko for finding out the test while working on MDEV-29986
      As a part of the patch, InnoDB should display undo tablespace name as undo001, undo002 and soon.

            Before MDEV-25312, the names of undo tablespaces were innodb_undo001, innodb_undo002, and so on. In MDEV-25312, the reported names for undo tablespaces were changed to NULL.

            To avoid dynamic allocation of strings, it could be better to introduce names like undo001, so that we can simply use a substring of the underlying file name. Regular tablespaces always contain a / in their names.

            In i_s_dict_fill_tablespaces_encryption(), could we allocate a buffer from the stack for the strings like innodb_undo001? In that way, the reported names for undo tablespaces would be the same as they were before MDEV-25312.
