fixes:

Fixes an missing MySQL/MariaDB character set configuration and default
|
|
table type encoding for the ``allocations`` database table. Previously,
|
|
If Ironic's database was attempted to be populated on a machine which
|
|
was using 4 byte character encoding, such as MySQL/MariaDB on Debian
|
|
based systems, then the database schema creation would fail.
|
|
upgrade:
|
|
- This upgrade updates the default character set to utilized in the
|
|
database tables when using MySQL/MariaDB. Previously, the default
|
|
for Ironic was ``UTF8``, however we now explicitly set ``UTF8MB3``
|
|
which is short for "3 byte UTF8" encoding. The exception to this
|
|
is the ``allocations`` table, which would just rely upon the database
|
|
default. This was done as Ironic's database schema is incompatible
|
|
with MySQL/MariaDB's ``UTF8MB4``, or "4 byte UTF8" character encoding
|
|
and storage constraints.
|
|
- Upgrading will change the default character encoding of all tables.
|
|
For most tables, this should be an effective noop, but may result in
|
|
transitory table locks. For the ``allocations`` table, it will need to
|
|
be re-written, during which the database engine will have locked the
|
|
table from being used. Operators are advised to perform test upgrades
|
|
and set expectation and upgrade plans accordingly.
