strmake() calls are easy to get wrong. Add checks in extra
debug mode to identify possible exploits.
Remove some dead code.
Remove some off-by-one errors identified with new checks.
change the size of core files.
Suppress the 'setrlimit could not change the size of the core files'
warning in mysql-test-run. We do not want core files on some of the
PushBuild hosts, and PushBuild itself does not set --core-files, so
that warning is expected.
"Table is already up to date" vs. "OK"
On MacOSX 10.5 when you cast something to "bool"
(the built in C type) it takes values 0 or 1
instead of 0-255 as it seems to be on older compilers.
Fixed by removing the typecast (not needed).
No test case needed : there are tests that test it.
Index lookup does not always guarantee that we can
simply remove the relevant conditions from the WHERE
clause. Reasons can be e.g. conversion errors,
partial indexes etc.
The optimizer was removing these parts of the WHERE
condition without any further checking.
This leads to "false positives" when using indexes.
Fixed by checking the index reference conditions
(using WHERE) when using indexes with sub-queries.
The problem: ha_partition::read_range_first() could return a record that is
outside of the scanned range. If that record happened to be in the next
subsequent range, it would satisfy the WHERE and appear in the output twice.
(we would get it the second time when scanning the next subsequent range)
Fix:
Made ha_partition::read_range_first() check if the returned recod is within
the scanned range, like other read_range_first() implementations do.
crashes.
MySQL distributions contain a number of programs that are used only by
the MySQL test suite internally, i.e. they are not indended to be
invoked directly by a user. As a result, such programs are not
documented, do not have any built-in help or proper error reporting,
which may confuse users.
This patch fixes the problem with the following changes:
- mytest, libmysqltest and all references to them were removed from the
distribution since they are not used anymore
- bug25714 now displays an error message when run with incorrect
arguments or with the --help option
- mysql_client_test now does not call abort() in case of errors,
instead it does a clean exit() with a proper error status.
disables the option explicitely.
Changed the option location in code so that --help will show it in
lexical option order.
This is for bug #26215: mysql command line client should not strip
comments from SQL statements
failing 'INSTALL PLUGIN' statement doesn't work in embedded server
as we disable library loading there.
Fixed by enabling loading libraries (#define HAVE_DLOPEN), what also
makes UDF working in the embedded server.
Comparison of a BIGINT NOT NULL column with a constant arithmetic
expression that evaluates to NULL caused error 1048: "Column '...'
cannot be null".
Made convert_constant_item() check if the constant expression is NULL
before attempting to store it in a field. Attempts to store NULL in a
NOT NULL field caused query errors.
checked for each record'
The problem was in incorrectly calculated length of the buffer used to
store a hexadecimal representation of an index map in
select_describe(). This could result in buffer overrun and stack
corruption under some circumstances.
Fixed by correcting the calculation.
