Allow "rpm -q --whatprovides mysql-server" to return more than one row.
(all rows should be identical though)
support-files/rpm/server-prein.sh:
don't use "head -1" or "uniq" to avoid introducing new dependencies.
"sed" is already used in this script.
In parallel replication, there was an error case where we could call
my_error() in-between events. This causes the assertion, as the previous event
has reported ok status, but the following event has not yet reset the
diagnostics area. This happened when a worker thread detects that the SQL
driver thread is aborting, and when it gets an error from a prior commit at
the same time in wait_for_prior_commit().
Since this is already an error case, the code should be using
unregister_wait_for_prior_commit() instead of wait_for_prior_commit(). But
unregister is already done a bit later (from finish_event_group()), so just
removing the redundant call to wait_for_prior_commit() fixes the issue.

Bug #3329 Incomplete lower_case_table_names=2 implementation
The problem was that check_db_name() converted database names to lower case also in case of lower_case_table_names=2.
Fixed by removing the conversion in check_db_name for lower_case_table_names = 2 and instead converting db name to
lower case at same places as table names are converted.
Fixed bug that SHOW CREATE DATABASE FOO showed information for database 'foo'.
I also removed some checks of lower_case_table_names when it was enough to use table_alias_charset.
mysql-test/mysql-test-run.pl:
Added --use-copy argument to force mysql-test-run to copy files instead of doing symlinks. This is needed when you run
with test directory on another file system

Don't check lower_case_table_names when we can use table_alias_charset
sql/sql_db.cc:
Use cmp_db_names() for checking if current database changed.
mysql_rm_db() now converts db to lower case if lower_case_table_names was used.
Changed database options cache to use table_alias_charset. This fixed a bug where SHOW CREATE DATABASE showed wrong information.
sql/sql_parse.cc:
Change also db name to lower case when file names are changed.
Don't need to story copy of database name anymore when lower_case_table_names == 2 as check_db_name() don't convert in this case.
Updated arguments to mysqld_show_create_db().
When adding table to TABLE_LIST also convert db name to lower case if needed (same way as we do with table names).
sql/sql_show.cc:
mysqld_show_create_db() now also takes original name as argument for output to user.
sql/sql_show.h:
Updated prototype for mysqld_show_create_db()
sql/sql_table.cc:
In mysql_rename_table(), do same conversions to database name as we do for the file name
- MDEV-5689 ExtractValue(xml, 'substring(/x,/y)') crashes
- MDEV-5709 ExtractValue() with XPath variable references returns wrong result.
Description:
1. The main problem was that that nodeset_func->fix_fields() was
called in Item_func_xml_extractvalue::val_str() and
Item_func_xml_update::val_str(), which led in some cases to
execution of the XPath engine *before* having a parsed XML value.
Moved to Item_xml_str_func::fix_fields().
2. Cleanup: added a new method Item_xml_str_func::fix_fields() and moved
most of the code from Item_xml_str_func::fix_length_and_dec()
to Item_xml_str_func::fix_fields(), to follow the usual Item layout.
3. Cleanup: a parsed XML value is useless without the raw XML value
it was built from.
Previously the parsed and the raw values where stored in separate String
instances. It was hard to follow how they are synchronized.
Added a helper class XML which contains both parsed and raw values.
Makes things easier to read and modify.
4. MDEV-5709: const_item() could incorrectly return a "true"
result when XPath expression contains users/SP variable references.
Now nodeset_func->const_item() is also taken into account to
catch such cases.
5. Minor code enhancements.
A huge number in the "day" part of an interval made the code to return
a negative date erroneously. Adding a test to return an error on a too
large "day" value.
After constant table row substitution the where condition may be converted
to always true. The function calculate_cond_selectivity_for_table() should
take into account this possibility.

Bug#13608112 - 64048: MYSQL_PRINT_STATUS() MISSING FINAL FFLUSH()
Analysis:
While printing debug information, memory related information and event
related information were written to buffer after flushing it. Because of this,
these information were getting printed when we do the next flush.
Fix:
Instead of calling fflush() before writing memory and event
information, calling it after memory and event information.
Due to how gap locks work, two transactions could group commit together on the
master, but get lock conflicts and then deadlock due to different thread
scheduling order on slave.
For now, remove these deadlocks by running the parallel slave in READ
COMMITTED mode. And let InnoDB/XtraDB allow statement-based binlogging for the
parallel slave in READ COMMITTED.
We are also investigating a different solution long-term, which is based on
relaxing the gap locks only between the transactions running in parallel for
one slave, but not against possibly external transactions.
When a transaction fails in parallel replication, it should signal the error
to any following transactions doing wait_for_prior_commit() on it. But the
code for this was incorrect, and would not correctly remember a prior error
when sending the signal. This caused corruption when slave stopped due to an
error.
Fix by remembering the error code when we first get an error, and passing the
saved error code to wakeup_subsequent_commits().
Thanks to nanyi607rao who reported this bug on
maria-developers@lists.launchpad.net and analysed the root cause.
Analysis: XtraDB merge regression, at the end of mutex_spin_wait before goto mutex_loop
there is missing
if (prio_mutex) {
os_atomic_decrement_ulint(&prio_mutex->high_priority_waiters, 1);
}
Hence we get unbalanced waiter count.
Thanks to Laurynas Biveinis for finding this.
don't use mysql-5.6 change.
correct fix: zero-out rounded tail after the number was shifted because
of the carry digit (otherwise the carry digit will be zeroed out too).
Let TABLE_SHARE::tdc.free_tables, TABLE_SHARE::tdc.all_tables,
TABLE_SHARE::tdc.flushed and corresponding invariants be protected by
per-share TABLE_SHARE::tdc.LOCK_table_share instead of global LOCK_open.
Now if CREATE OR REPLACE fails but we have deleted a table already, we will generate a DROP TABLE in the binary log.
This fixes this issue.
In addition, for a failing CREATE OR REPLACE TABLE ... SELECT we don't generate a log of all the inserted rows, only the DROP TABLE.
I added code for not logging DROP TEMPORARY TABLE for tables where the CREATE TABLE was not logged. This code will be activated in 10.1
by removing the code protected by DONT_LOG_DROP_OF_TEMPORARY_TABLES.
