mysqldump generates view defitions in two stages:
- dump CREATE TABLE statements for the temporary tables. For each view a
temporary table, that has the same structure as the view is created.
- dump DROP TABLE statements for the temporary tables and CREATE VIEW
statements for the view.
This approach is required because views can have dependencies on each other
(a view can use other views). So, they should be created in the particular
order. mysqldump however is not smart enough, so in order to resolve
dependencies it creates temporary tables first of all.
The problem was that mysqldump might have generated incorrect dump for the
temporary table when a view has non-ASCII column name. That happened when
default-character-set is not utf8.
The fix is to:
1. Switch character_set_client for the mysqldump's connection to binary
before issuing SHOW FIELDS statement in order to avoid conversion.
2. Dump switch character_set_client statements to UTF8 and back for
CREATE TABLE statement that is issued to create temporary table.
For each view the mysqldump utility creates a temporary table
with the same name and the same columns as the view
in order to satisfy views that depend on this view.
After the creation of all tables, mysqldump drops all
temporary tables and creates actual views.
However, --skip-add-drop-table and --compact flags disable
DROP TABLE statements for those temporary tables. Thus, it was
impossible to create the views because of existence of the
temporary tables with the same names.
sometimes `mysqldump --hex-blob' overruned output buffer by '\0' byte.
The dump_table() function has been fixed to reserve 1 byte more for the
last '\0' byte of dumped string.
mysqldump didn't properly handle getting no data on
SHOW CREATE PROCEDURE. If S/C/P fails (due to dumping
user's insufficient privileges on mysql.proc, say),
mysqldump will print a comment to that effect to the
output and return an error-code. If the -f (force) option
is used, the dump will continue, otherwise, it will abort
right there and then.
Also fixes Bug#22761, "mysqldump reports no errors when using
--routines without mysql.proc privileges"

- Giving the directive '--all-databases' to mysqldump caused
an attempt to lock and dump log tables which don't support this
operation.
- With this patch the log tables are excluded from the set of
databases tables to dump.
- mysqldump executes a SHOW CREATE VIEW statement to generate the text
that it outputs. When the function name is retrieved it's database
name is unconditionally prepended. This change causes the function's
database name to be prepended only when it was used to define the
function.
Moved .progress files into the log directory
Moved 'cluster' database tables into the MySQL database, to not have 'cluster' beeing a reserved database name
Fixed bug where mysqld got a core dump when trying to use a table created by MySQL 3.23
Fixed some compiler warnings
Fixed small memory leak in libmysql
Note that this doesn't changeset doesn't include the new mysqldump.c code required to run some tests. This will be added when I merge 5.0 to 5.1
The mysqldump command with both the --xml and --hex-blob options will output blob data encoded as hexBinary.
The proper XML datatype is xs:hexBinary.
The correct XML datatype is specified be setting the xsi_type attribute equal to xs:hexBinary for each encoded element.
