Public bug reported:
Following apis are returning 500 error if user passes name with more
than 80 characters:
* md-tag-create
* md-tag-update
* md-object-create
* md-object-update
* md-property-create
* md-property-update
This happens because there is a discrepancy in db column length and
glance-api length check in schema validation. In database the 'name'
field for these API's is defined as of maximum 80 characters and in
schema it is defined as of maximum 255 characters. So if user passes
name with more than 80 characters and less than 255 characters
database fails to store that value and shouts with following error
which leads to 500 error to API user:
(pymysql.err.DataError) (1406, u"Data too long for column 'name' at
row 1")
Steps to reproduce:
