6135a547b2 Merge fix for PBXT running inside embedded server (MBug#439889).
Also some small fixes to make the PBXT testsuite work in --embedded.

config/ac-macros/plugins.m4:
  MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS macro extended to support multiple files.
mysql-test/std_data/pbxt_load_unique_error1.inc:
  Move file to be accessible also for testing embedded server.
mysql-test/suite/pbxt/r/pbxt_bugs.result:
  Fix LOAD DATA LOCAL INFILE path so it works also for testing embedded server.
mysql-test/suite/pbxt/t/pbxt_bugs.test:
  Fix LOAD DATA LOCAL INFILE path so it works also for testing embedded server.
mysql-test/suite/pbxt/t/pbxt_locking.test:
  Disable for embedded, as it needs SHOW PROCESSLIST functionality not available there.
mysql-test/suite/pbxt/t/pbxt_transactions.test:
  Disable test for embedded, as it needs ability to connect from outside (mysqldump).
mysql-test/suite/pbxt/t/ps_1general.test:
  Fix replace_result for new mysql-test-run.pl.

  Remove hack that disables PBXT in embedded.
storage/pbxt/plug.in:
  Fix crash in PBXT in embedded server.
storage/pbxt/src/Makefile.am:
  Remove not needed CFLAGS/CXXFLAGS (they cause autotools to generate different object names, which in turn cause the MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS replacement of object files inside library files not to work).
storage/pbxt/src/ha_pbxt.cc:
  Ugly hack to allow more threads in embedded server (need a better fix I think).
storage/pbxt/src/table_xt.cc:
  Use stderr for logging not stdout (prevent spamming --embedded test suite output with stray messages).
storage/pbxt/src/thread_xt.cc:
  Use stderr for logging not stdout (prevent spamming --embedded test suite output with stray messages).
storage/pbxt/src/trace_xt.cc:
  Use stderr for logging not stdout (prevent spamming --embedded test suite output with stray messages).

0df8279c46 Fixes after comments from last push:
- Removed some not needed casts
- Change plugin.h to be 'binary compatible' with old versions

d13c54351d Remove compiler warnings (Including some warnings from -Wstrict-aliasing)
Don't use static link by default (in compile-pentium) as some new systems doesn't have all static libraries available
Change type for functions in plugin.h:str_mysql_ftparser_param() to const unsigned char and string lengths to size_t.
One effect of the above change is that one needs to include mysql_global.h or define size_t before including plugin.h

a962160eec Merge with MySQL 5.1, with following additions:
- Moved some code from innodb_plugin to xtradb, to ensure that all tests runs
- Did changes in pbxt and maria storage engines becasue of changes in thd->query
- Reverted wrong code in sql_table.cc for how ROW_FORMAT is used.

This is a re-commit of Monty's merge to eliminate an extra commit from
MySQL-5.1.42 that was accidentally included in the merge.

This is a merge of the MySQL 5.1.41 clone-off (clone-5.1.41-build). In
case there are any extra changes done before final MySQL 5.1.41
release, these will need to be merged later before MariaDB 5.1.41
release.

cb0cca8655 A fix and a test case for
Bug#41756 "Strange error messages about locks from InnoDB".
      
In JT_EQ_REF (join_read_key()) access method, 
don't try to unlock rows in the handler, unless certain that 
a) they were locked
b) they are not used.

Unlocking of rows is done by the logic of the nested join loop,
and is unaware of the possible caching that the access method may
have. This could lead to double unlocking, when a row
was unlocked first after reading into the cache, and then 
when taken from cache, as well as to unlocking of rows which
were actually used (but taken from cache).
      
Delegate part of the unlocking logic to the access method,
and in JT_EQ_REF count how many times a record was actually 
used in the join. Unlock it only if it's usage count is 0.

Implemented review comments.

bec35067d3 Bug#48177 - SELECTs with NOT IN subqueries containing NULL
values return too many records

WHERE clauses with "outer_value_list NOT IN subselect" were
handled incorrectly if the outer value list contained multiple 
items where at least one of these could be NULL. The first 
outer record with NULL value was handled correctly, but if a 
second record with NULL value existed, the optimizer would 
choose to reuse the result it got on the last execution of the 
subselect. This is incorrect if the outer value list has 
multiple items.
     
The fix is to make Item_in_optimizer::val_int (in 
item_cmpfunc.cc) reuse the result of the latest execution
for NULL values only if all values in the outer_value_list 
are NULL.

9819885177 BUG#48216 Replication fails on all slaves after upgrade to 5.0.86 on master
When a sessione is closed, all temporary tables of the session are automatically 
dropped and are binlogged. But it will be binlogged with wrong database names when
the length of the temporary tables' database names are greater than the 
length of the current database name or the current database is not set.

Query_log_event's db_len is forgot to set when Query_log_event's db is set.
This patch wrote code to set db_len immediately after db has set.

e080080711 Bug#47571: idle named pipe connection is unkillable
Bug#31621: Windows server hanging during shutdown using named pipes 
           and idle connection
            
Problem: when idle pipe connection is forcefully closed with KILL
statement or when the server goes down, thread that is closing connection
would hang infinitely in CloseHandle(). The reason for the hang is that 
named pipe operations are performed synchronously. In this mode all IOs
on pipe are serialized, that is CloseHandle() will not abort ReadFile() 
in another thread, but wait for ReadFile() to complete.
            
The fix implements asynchrnous mode for named pipes, where operation of file
are not synchronized. Read/Write operation would fire an async IO and wait for
either IO completion or timeout.
            
Note, that with this patch timeouts are properly handled for named pipes.
      
Post-review: Win32 timeout code has been fixed for named pipes and shared
memory. We do not store pointer to NET in vio structure, only the read and 
write timeouts.


include/violite.h:
  Add pipe_overlapped to Vio structure for async IO for named pipes.
sql-common/client.c:
  Use asynchronous pipe IO.
sql/mysqld.cc:
  Use asynchronous pipe IO.
vio/vio.c:
  -Refactor timeouts for win32 protocols: shared memory and named pipes.
  Store read/write timeout in VIO structure, instead of storing pointer
  to NET. New function vio_win32_timeout called indirectly via 
  vio_timeout changes these values.
vio/vio_priv.h:
  Remove vio_ignore_timeout.
  Add vio_win32_timeout to be used for named pipes and shared memory.
vio/viosocket.c:
  Use async IO for named pipes.
  After issuing IO, wait for either IO completion, pipe_close_event
  or timeout.
          
  Refactor timeouts for named pipe and shared memory.

740b7c4e36 Bug#47925: regression of range optimizer and date comparison in 5.1.39!
When a query was using a DATE or DATETIME value formatted
using any other separator characters beside hyphen '-', a
query with a greater-or-equal '>=' condition matching only
the greatest value in an indexed column, the result was
empty if index range scan was employed.

The range optimizer got a new feature between 5.1.38 and
5.1.39 that changes a greater-or-equal condition to a
greater-than if the value matching that in the query was not
present in the table. But the value comparison function
compared the dates as strings instead of dates.

The bug was fixed by splitting the function
get_date_from_str in two: One part that parses and does
error checking. This function is now visible outside the
module. The old get_date_from_str now calls the new
function.

b67cdaa351 Bug #48131: crash group by with rollup, distinct, filesort,
with temporary tables

There were two problems the test case from this bug was
triggering:

1. JOIN::rollup_init() was supposed to wrap all constant Items
into another object for queries with the WITH ROLLUP modifier
to ensure they are never considered as constants and therefore
are written into temporary tables if the optimizer chooses to
employ them for DISTINCT/GROUP BY handling.

However, JOIN::rollup_init() was called before
make_join_statistics(), so Items corresponding to fields in
const tables could not be handled as intended, which was
causing all kinds of problems later in the query execution. In
particular, create_tmp_table() assumed all constant items
except "hidden" ones to be removed earlier by remove_const()
which led to improperly initialized Field objects for the
temporary table being created. This is what was causing crashes
and valgrind errors in storage engines.

2. Even when the above problem had been fixed, the query from
the test case produced incorrect results due to some
DISTINCT/GROUP BY optimizations being performed by the
optimizer that are inapplicable in the WITH ROLLUP case.

Fixed by disabling inapplicable DISTINCT/GROUP BY optimizations
when the WITH ROLLUP modifier is present, and splitting the
const-wrapping part of JOIN::rollup_init() into a separate
method which is now invoked after make_join_statistics() when
the const tables are already known.

mysql-test/r/olap.result:
  Added a test case for bug #48131.
mysql-test/t/olap.test:
  Added a test case for bug #48131.
sql/sql_select.cc:
  1. Disabled inapplicable DISTINCT/GROUP BY optimizations when
  the WITH ROLLUP modifier is present.
  2. Split the const-wrapping part of JOIN::rollup_init() into a
  separate method.
sql/sql_select.h:
  Added rollup_process_const_fields() declaration.

9d96cd6dcb Bug #48291 : crash with row() operator,select into @var, and
subquery returning multiple rows

Error handling was missing when handling subqueires in WHERE 
and when assigning a SELECT result to a @variable.
This caused crash(es). 

Fixed by adding error handling code to both the WHERE 
condition evaluation and to assignment to an @variable.

851e250953 Bug #48293: crash with procedure analyse, view with > 10 columns,
having clause...

The fix for bug 46184 was not very complete. It was not covering
views using temporary tables and multiple tables in a FROM clause.
Fixed by reverting the fix for 46184 and making a more general
check that is checking at the right execution stage and for all
of the non-supported cases.
Now PROCEDURE ANALYZE on non-top level SELECT is also forbidden.
Updated the analyse.test and subselect.test accordingly.
