After sending packet that is too large, clienrt can get either an error packet with
ER_NET_PACKET_TOO_LARGE, or a socket error. Both cases are valid, since the
server does not ensure reply was fully read by client, before shutting down and closing
the socket.
Refactored the test case: hardened and extended it. Created test inc file
to abstract the task of relocating binlogs.
Also, disabled it on windows for not cluttering the test case any further,
as it depends heavily on doing filesystem operations and path handling.
mysql-test/include/relocate_binlogs.inc:
Auxiliar include file that performs the relocation of binary logs
listed in an index file.
The tables from the same semi-join or outer join nest cannot use
join buffers if in the join sequence of the query execution plan
they are separated by a table that is planned to be joined without
usage of a join buffer.

sql/sql_base.cc:
Don't print table names for placeholders.
sql/sql_show.cc:
Temporary fix:
Save and restore db and table_name in mysqld_show_create (to get rid of valgrind warning)
A better solution that needs to be investgated is to not change these fields in mysql_derived_prepare()
sql/sql_view.cc:
Fixed valgrind warning
storage/xtradb/handler/ha_innodb.cc:
Don't access THD directly
mysql-test/lib/My/Options.pm:
My::Options::is_set() now matches both option names and values!
mysql-test/lib/mtr_cases.pm:
1. don't merge --plugin-load here, it's too early
2. don't skip combinations that set --plugin-load just because the test needs another --plugin-load.
Skip *only* if test's --plugin-load matches *exactly* --plugin-load of one of the combinations.
3. if skipping all combinations but one, still assign the test to the combination
mysql-test/mysql-test-run.pl:
1. remove dead code - don't set variables that aren't used.
2. bugfix: allow one-letter combination names
3. in the command line, merge all --plugin-load options in one
storage/federated/ha_federated.cc:
bugfix: garbage character in the generated SELECT query
The cause of the wrong result was that Item_ref_null_helper::get_date()
didn't use a method of the *_result() family, and fetched the data
for the field from the current row instead of result_field. Changed to
use the correct *_result() method, like to all other similar methods
of Item_ref_null_helper.
There was memory leak when running some tests on PB2.
The reason of the failure is an early return from change_master()
that was supposed to deallocate a dyn-array.
Fixed with relocating the dyn-array's destructor at ~LEX() that is
the end of the session, per Gleb's patch idea.
Two optimizations were done: the static buffer for the dyn-array to base on,
and the array initialization is called precisely when it's necessary rather than
per each CHANGE-MASTER as before.
mysql-test/suite/rpl/t/rpl_empty_master_host.test:
the test is binlog-format insensitive so it will be run with MIXED mode only.
sql/sql_lex.cc:
the new flag is initialized.
sql/sql_lex.h:
A new bool flag new member to LEX.mi is added to stay UP since after
LEX.mi.repl_ignore_server_ids dynarray initialization was called
for the first time on the session. So it is set once and its life time
is session.
The array is destroyed at the end of the session.
sql/sql_repl.cc:
dyn-array destruction is relocated to ~LEX.
sql/sql_yacc.yy:
Refining logics of Lex->mi.repl_ignore_server_ids initialization.
The array is initialized once a corresponding option in CHANGE MASTER token sequence
is found.
The fact of initialization is memorized into the new flag.
1. main.merge fails with errno 13 in copy_file().
The reason for the error is that copy_file tries to create a file with the same name as recently deleted one,
and there is still an open handle for the deleted file.
To fix, use my_delete_allow_opened() for MTR's delete_file. On Windows, this renames file to unique name
prior to deletion, and prevents EACCES errors for files opened with FILE_SHARE_DELETE.
2. innodb_bug59641
generates warnings, after server was killed and restarted in the test case.
The warnings are about test_suppression table (needs to be repaired, as it that was written just prior to the crash)
Fixed by using FLUSH TABLES after populating warning suppression table.

storage/xtradb/row/row0ins.c:

incorrect errors in the innodb.test too
Analysis:
lp:894397 was a consequence of a prior incorrect fix of lp:833777
which didn't take into account that even when all tables are
constant there may be correlated conditions, and the where clause
is not equivalent to the constant conditions.
Solution:
When there are constant tables only, evaluate only the conditions
that reference outer fields, because the constant conditions are
already checked, and the where clause doesn't have other conditions
than constant ones, and outer referencing ones. The fix for
lp:894397 also fixes lp:833777.
The problem was that when we have single row subquery with no rows
Item_cache(es) which represent result row was not null and being
requested via element_index() returned random value.
The fix is setting all Item_cache(es) in NULL before executing the
query (reset() method) which guaranty NULL value of whole query
or its elements requested in any way if no rows was found.
set_null() method was added to Item_cache to guaranty correct NULL
value in case of reseting the cache.
- Make EXPLAIN display "Start temporary" at the start of the fanout (it used to display
at the first table whose rowid gets into temp. table which is not that useful for
the user)
- Updated test results (all checked)
BIN LOG HAS BEEN MOVED
When moving the binary/relay log files from one location to
another and restarting the server with a different log-bin or
relay-log paths, would cause the startup process to abort. The
root cause was that the server would not be able to find the log
files because it would consider old paths for entries in the
index file instead of the new location. What's even worse, the
relative paths would not be considered relative to the path
provided in log-bin and relay-log, but to mysql_data_dir.
We fix the cases where the server contains relative paths. When
the server is reading from the index file, it checks whether the
entry contains relative paths. If it does, we replace it with the
absolute path set in log-bin/relay-log option. Absolute paths
remain unchanged and the index must be manually edited to
consider the new log-bin and/or relay-log path (this should be
documented). This is a fix for a GA version, that does not break
behavior (that much).
For development versions, we should go with Zhenxing's approach
that removes paths altogether from index files.
mysql-test/include/begin_include_file.inc:
Added parameter to keep the begin_include_file.inc silent. Useful when
including scripts that contain platform dependent parameters, for example:
--let $rpl_server_parameters=--log-bin=$tmpdir/slave-bin --relay-log=$tmpdir/slave-relay-bin
--let $keep_include_silent=1
source include/rpl_start_server.inc;
--let $keep_include_silent=0
We want the paths ($tmpdir/slave-bin and $tmpdir/slave-relay-bin) not to be in the
result file.
mysql-test/suite/rpl/t/rpl_binlog_index.test:
Test case.
sql/log.cc:
When finding the corresponding log entry in the index file, we first
normalize the paths before doing the comparison. This will make relative
paths to be turned into absolute paths (based on the opt_bin_logname or
opt_relay_logname) and then compared against also, expanded paths entered,
through CHANGE MASTER for instance.
sql/log.h:
Added normalize_binlog_name, which turns relative paths, into absolute paths
given the parameter: is_relay_log ? opt_relay_logname : opt_bin_logname .
sql/mysqld.cc:
Exposing opt_bin_logname.
sql/mysqld.h:
Exposing opt_bin_logname.
When passing an empty user to the connect function will cause
valgrind warnings. Seems that the client code is not prepared
to handle empty users. On 5.6 this can even be triggered by
START SLAVE PASSWORD='...'; i.e., without setting USER='...' on
the START SLAVE command (see WL#4143 for details on the new
additional START SLAVE commands).
To fix this, we disallow empty users when configuring the slave
connection parameters (this decision might be revisited if the
client code accepts empty users in the future).
sql/slave.cc:
We throw an error if an empty user is supplied to the connection
function.

per-file comments:
mysql-test/t/gis-precise.test
number-to-string conversion differs on Windows.
Have to tolerate this while GIS data is stored in doubles.
sql/spatial.cc
prev_x initialization added.
Analysis:
The bug is a result of an incomplete fix for bug lp:869036.
That fix didn't take into account that there may be a case
when ther are no NULLs in the materialized subquery, however
all columns without NULLs may not be grouped in the only
non-null index. This is the case when the left subquery expression
has nullable columns.
Solution:
The patch handles two missing sub-cases of the case when there are
no value (non-null matches) for any outer expression, and there are
both NULLs and non-NUll values in the outer reference.
a) If the materialized subquery contains no NULLs there cannot be a
partial match, because there are no NULLs in those columns where
the outer reference has no NULLs.
b) If the materialized subquery contains NULLs, but there exists a
column, such that its corresponding outer expression has no NULL,
and this column also has no NULL. Then there cannot be a partial
match either.
AND HANG IN SHOW TABLE STATUS.
ISSUE: Table corruption due to concurrent queries.
Different threads running insert and check
query leads to table corruption. Not properly locked,
rows are inserted in between check query.
SOLUTION: In check query mutex lock is acquired
for a longer time to handle concurrent
insert and check query.
NOTE: Additionally we backported the fix for CHECKSUM
issue(bug#11758979).
- Break down POSITION/advance_sj_state() into four classes
representing potential semi-join strategies.
- Treat all strategies uniformly (before, DuplicateWeedout
was special as it was the catch-all strategy. Now, we're
still relying on it to be the catch-all, but are able to
function,e.g. with firstmatch=on,duplicate_weedout=off.
- Update test results (checked)
