mariadb/mysql-test/r/bdb.result
unknown 5a1b7ddb68 Partial rollback of fix for bug #30059: End-space truncation is inconsistent 
or incorrect.

For better conformance with standard, truncation procedure of CHAR columns
has been changed to ignore truncation of trailing whitespace characters
(note has been removed).

Finally, for columns with non-binary charsets:

1. CHAR(N) columns silently ignore trailing whitespace truncation;
2. VARCHAR and TEXT columns issue Note about truncation.

BLOBs and other columns with BINARY charset are unaffected.

  The Field_string::store method has been changed to
  ignore trailing whitespace truncation (CHAR column
  type).
sql/field.h:
  Post-commit fix for bug #30059.
  
  The Field_longstr::report_if_important_data method declaration
