Documented behaviour was broken by the patch for bug 33699
that actually is not a bug.
This fix reverts patch for bug 33699 and reverts the
UPDATE of NOT NULL field with NULL query to old
behavior.
Adds --general-log-file, --slow-query-log-file command-
line options to match system variables of the same names.
Deprecates --log, --log-slow-queries command-line option
and log, log_slow_queries system-variables for v7.0; they
are superseded by general_log/general_log_file and
slow_query_log/slow_query_log_file, respectively.
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.
Server handles truncation for assignment of too-long values
into CHAR/VARCHAR/TEXT columns in a different ways when the
truncated characters are spaces:
1. CHAR(N) columns silently ignore end-space truncation;
2. TEXT columns post a truncation warning/error in the
non-strict/strict mode.
3. VARCHAR columns always post a truncation note in
any mode.
Space truncation processing has been synchronised over
CHAR/VARCHAR/TEXT columns: current behavior of VARCHAR
columns has been propagated as standard.
Binary-encoded string/BLOB columns are not affected.
columns (default datatype value is assigned).
The mysql_update function has been modified to generate
an error when trying to set a NOT NULL field to NULL rather than a warning
in the set_field_to_null_with_conversions function.
Post-commit issues fixed
* Test results for other tests fixed due to added error #s
* Memory allocation/free issues found with running with valgrind
* Fix to mysql-test-run shell script to run federated_server test (installs
mysql.servers table properly)
The function receives an exactly-sized buffer (not a C NUL-terminated string)
and passes it into a printf function to be interpreted with "%s".
Instead, create an intermediate String object, and copy the data into it,
and pass in a pointer to the String's NUL-terminated buffer.

Fixed confusing warning.
Quoting INSERT section of the manual:
----
Inserting NULL into a column that has been declared NOT NULL. For
multiple-row INSERT statements or INSERT INTO ... SELECT statements, the
column is set to the implicit default value for the column data type. This
is 0 for numeric types, the empty string ('') for string types, and the
"zero" value for date and time types. INSERT INTO ... SELECT statements are
handled the same way as multiple-row inserts because the server does not
examine the result set from the SELECT to see whether it returns a single
row. (For a single-row INSERT, no warning occurs when NULL is inserted into
a NOT NULL column. Instead, the statement fails with an error.)
----
This is also true for LOAD DATA INFILE. For INSERT user can specify
DEFAULT keyword as a value to set column default. There is no similiar
feature available for LOAD DATA INFILE.
The problem was that when converting a string to an exact number,
rounding didn't work, because conversion didn't understand
approximate numbers notation.
Fix: a new function for string-to-number conversion was implemented,
which is aware of approxinate number notation (with decimal point
and exponent, e.g. -19.55e-1)
produce warning for 'create database if not exists' if database exists
do not update database options in this case
produce warning for 'create table if not exists' if table exists
