column is used for ORDER BY
Problem: filesort isn't meant for null length sort data
(e.g. char(0)), that leads to a server crash.
Fix: disregard sort order if sort data record length is 0 (nothing
to sort).

Fix for bug#49897: crash in ptr_compare when char(0) NOT NULL
column is used for ORDER BY
- don't sort null length data e.g. in case of ORDER BY CHAR(0).
- Added tests for innodb and semisync plugin
- Modified existing tests to include variable values in I_S tables

in multitable delete/subquery
SQL_BUFFER_RESULT should not have an effect on non-SELECT
statements according to our documentation.
Fixed by not passing it through to multi-table DELETE (similarly
to how it's done for multi-table UPDATE).

message:
Bug #45989 take 2 : memory leak after explain encounters an
error in the query.
Fixes a leak after materializing a GROUP BY subquery to a
temp table when the subquery has a blob column in the SELECT
list.
Fixed by correctly destructing temporary buffers after doing
the conversion.

printstack() being present
When Bug#47391 was fixed, no assumption was made that support
for Solaris 8 was needed. Solaris 8 lacks printstack(), and
the build breaks because of this.
This patch adds a test for the presence of printstack() to
configure.in for 5.0, and uses HAVE_PRINTSTACK to make
decisions rather than the __sun define.
The 'rpl_get_master_version_and_clock' test verifies if the slave I/O
thread tries to reconnect to master when it tries to get the values of
the UNIX_TIMESTAMP, SERVER_ID from master under network disconnection.
So the master server is restarted for making the transient network
disconnection, during the period the COM_REGISTER_SLAVE failures are
produced in server log file when the slave I/O thread tries to
register on master.
To fix the problem, suppress COM_REGISTER_SLAVE failures in server log
file by mtr suppression, because they are expected.
mysql-test/suite/rpl/r/rpl_get_master_version_and_clock.result:
Removed mtr.add_suppression("Get master clock failed with error: ")
and mtr.add_suppression("Get master SERVER_ID failed with error: ").
Because they are suppressed globally.
MySQL's hash functions MD5 and SHA relied on the somewhat slow
sprintf function to convert the digests to hex representations.
This patch replaces the sprintf with a specific and inline hex
conversion function.
Patch contributed by Jan Steemann.
sql/item_strfunc.cc:
Add a hex conversion function.
Bug #45856 can't switch from binlog_format=row to mix with open tmp tbl
If binlog_format=MIXED, there are open temporary tables, an unsafe statement
is executed, and the user issues 'SET @@session.binlog_format = STATEMENT',
then subsequent DML statements will be written in row format despite
binlog_format=STATEMENT. Because the binlog format can't be reset to
statement based by 'reset_current_stmt_binlog_row_based' function.
If binlog_format=ROW, there are open temporary tables, and an unsafe statement
is executed, then the statement 'SET @@session.binlog_format = MIXED' generates
the error:
"Cannot switch out of the row-based binary log format when the session has open
temporary tables"
However, it is safe to switch to MIXED mode because events in row format are allowed.
To fix the above two problems, generate ER_TEMP_TABLE_PREVENTS_SWITCH_OUT_OF_RBR
and forbid switching from MIXED or ROW to STATEMENT when there are open temp
tables and we are logging in row format. There is no error in any other case.
mysql-test/suite/binlog/r/binlog_format_switch_in_tmp_table.result:
Test result for bug#45855 and bug#45856.
mysql-test/suite/binlog/t/binlog_format_switch_in_tmp_table.test:
Added test file to verify if the program will generate
ER_TEMP_TABLE_PREVENTS_SWITCH_OUT_OF_RBR error and forbid
switching from MIXED or ROW to STATEMENT when there are
open temp tables and we are logging in row format. There
is no error in any other case.
Before this fix, opening a configuration file located under "~" failed.
To evaluate the "~" path, home_dir needs to be initialized.
The 'home_dir' variable was initialized too late in my_init().
This fix:
- moved the home_dir initialization from my_init() to my_basic_init(),
using getenv("HOME"))
- moved the initialization of my_umask / my_umask_dir also to
my_basic_init(), to have all the my_umask / my_umask_dir init code in the
same place.
The second part is not strictly required, but makes the code more
maintainable.
Tested the fix manually.
No MTR tests added, because MTR should not access or modify the $HOME
directory of the user running tests.
