762df2d05c Additional fix for bug#31455 (rpl decoder)
- Implementing --base64-format=decode-rows, to display
  SQL-alike decoded row events without their BINLOG statements.
- Adding --base64-format=decode-rows into tests when
  calling mysqlbinlog to avoid non-deterministic results
- Removing resetting of last_table_id in "RESET MASTER",
  which appeared to be dangerous.

9d9fa39b97 Cherry-pick fix for Bug#35220 from innodb-5.0-ss2475 snapshot.
Bug#35220: ALTER TABLE too picky on reserved word "foreign"

In ALTER TABLE, change the internal parser to search for
``FOREIGN[[:space:]]'' instead of only ``FOREIGN'' when parsing
ALTER TABLE ... DROP FOREIGN KEY ...; otherwise it could be mistaken
with ALTER TABLE ... DROP foreign_col;

(This fix is already present in MySQL 5.1 and higher.)

dc593c3ec4 Cherry-pick InnoDB fixes for Bug#34286, Bug#35352, and Bug#36600 from snapshot
innodb-5.0-ss2475.

Bug #34286  Assertion failure in thread 2816 in file .\row\row0sel.c line 3500
Since autoinc init performs a MySQL SELECT query to determine the auto-inc
value, set prebuilt->sql_stat_start = TRUE so that it is performed like any
normal SELECT, regardless of the context in which it was invoked.


Bug #35352  If InnoDB crashes with UNDO slots full error the error persists on restart
We've added a heuristic that checks the size of the UNDO slots cache lists
(insert and upate). If either of cached lists has more than 500 entries then we
add any UNDO slots that are freed, to the common free list instead of the cache
list, this is to avoid the case where all the free slots end up in only one of
the lists on startup after a crash.

Tested with test case for 26590 and passes all mysql-test(s).

Bug #36600  SHOW STATUS takes a lot of CPU in buf_get_latched_pages_number
Fixed by removing the Innodb_buffer_pool_pages_latched variable from SHOW
STATUS output in non-UNIV_DEBUG compilation.

ae4a35fd5c Bug#37662 nested if() inside sum() is parsed in exponential time
min() and max() functions are implemented in MySQL as macros.
This means that max(a,b) is expanded to: ((a) > (b) ? (a) : (b))
Note how 'a' is quoted two times.
Now imagine 'a' is a recursive function call that's several 10s of levels deep.
And the recursive function does max() with a function arg as well to dive into
recursion.
This means that simple function call can take most of the clock time.
Identified and fixed several such calls to max()/min() : including the IF() 
sql function implementation.

dd85aa78ba Bug#37830 : ORDER BY ASC/DESC - no difference
Range scan in descending order for c <= <col> <= c type of
ranges was ignoring the DESC flag.
However some engines like InnoDB have the primary key parts 
as a suffix for every secondary key.
When such primary key suffix is used for ordering ignoring 
the DESC is not valid.
But we generally would like to do this because it's faster.
            
Fixed by performing only reverse scan if the primary key is used.
Removed some dead code in the process.

6b584b80da Bug#23921: random failure of user_limits.test
mysqltest disconnect/connect-combo could be so
quick that connect would hit the server before
it had processed the disconnect. Since that
resulted in one more concurrent connection than
we meant to have, global or per-user
max-user-connections could be exceeded.
This could lead to "random" failures in tests
that set those limits.

  connect_n_handle_errors() unexpectedly fails
  on connection-limit as this could be a race.

e73e7bb9ae Bug#35577 (CREATE PROCEDURE causes either crash or syntax error depending on
build)

The crash was caused by freeing the internal parser stack during the parser
execution.
This occured only for complex stored procedures, after reallocating the parser
stack using my_yyoverflow(), with the following C call stack:
- MYSQLparse()
- any rule calling sp_head::restore_lex()
- lex_end()
- x_free(lex->yacc_yyss), xfree(lex->yacc_yyvs)

The root cause is the implementation of stored procedures, which breaks the
assumption from 4.1 that there is only one LEX structure per parser call.

The solution is to separate the LEX structure into:
- attributes that represent a statement (the current LEX structure),
- attributes that relate to the syntax parser itself (Yacc_state),
so that parsing multiple statements in stored programs can create multiple
LEX structures while not changing the unique Yacc_state.

Now, Yacc_state and the existing Lex_input_stream are aggregated into
Parser_state, a structure that represent the complete state of the (Lexical +
Syntax) parser.

e000e4a2a2 Bug #37761: IN handles NULL differently for table-subquery
and value-list

The server returns unexpected results if a right side of the 
NOT IN clause consists of NULL value and some constants of
the same type, for example:

  SELECT * FROM t WHERE NOT t.id IN (NULL, 1, 2) 
  
may return 3, 4, 5 etc if a table contains these values.


The Item_func_in::val_int method has been modified:
unnecessary resets of an Item_func_case::has_null field 
value has been moved outside of an argument comparison
loop. (Also unnecessary re-initialization of the null_value
field has been moved).

d4b0fcc90a Bug#35736 Test 'parts.partition_basic_symlink_myisam' depends on output of 'ls'
The problem is that relying on the output of the 'ls' command is not
portable as its behavior is not the same between systems and it might
even not be available at all in (Windows).

So I added list_files that relies on the portable mysys library instead.
(and also list_files_write_file and list_files_append_file,
since the test was using '--exec ls' in that way.)

  list_files <dirname> [<filename incl. wild-cards>]
  is equivalent to 'ls <dirname>/[<filename incl. wild-cards>]'
  
  list_files_write_file creates/overwrites a file with the content
  list_files_append_file creates/appends a file with the content

d11d5cfca8 Bug#35745: SELECT COUNT(*) is not correct for some partitioned tables.
problem was that ha_partition::records was not implemented, thus
using the default handler::records, which is not correct if the engine
does not support HA_STATS_RECORDS_IS_EXACT.
Solution was to implement ha_partition::records as a wrapper around
the underlying partitions records.

The rows column in explain partitions will now include the total
number of records in the partitioned table.

(recommit after removing out-commented code)

c7724872d8 Bug#26030 (Parsing fails for stored routine w/multi-statement execution
enabled)

Before this fix, the lexer and parser would treat the ';' character as a
different token (either ';' or END_OF_INPUT), based on convoluted logic,
which failed in simple cases where a stored procedure is implemented as a
single statement, and used in a multi query.

With this fix:
- the character ';' is always parsed as a ';' token in the lexer,
- parsing multi queries is implemented in the parser, in the 'query:' rules,
- the value of thd->client_capabilities, which is the capabilities
  negotiated between the client and the server during bootstrap,
  is immutable and not arbitrarily modified during parsing (which was the
  root cause of the bug)

0e1709bde6 Bug#37627: Killing query with sum(exists()) or avg(exists()) reproducibly crashes server
When there is an error executing EXISTS predicates they return NULL as their string
or decimal value but don't set the NULL value flag.
Fixed by returning 0 (as a decimal or a string) on error exectuting the subquery.
Note that we can't return NULL as EXISTS is not supposed to return NULL.

7b8bfb2a93 A fix for
Bug#12093 "SP not found on second PS execution if another thread 
drops other SP in between" and
Bug#21294 "executing a prepared statement that executes a stored 
function which was recreat"

Stored functions are resolved at prepared statement prepare only.
If someone flushes the stored functions cache between prepare and
execute, execution fails.

The fix is to detect the situation of the cache flush and automatically
reprepare the prepared statement after it.

sql/sp_cache.cc:
  Implement sp_cache_version() -- returns the current version of 
  a stored routines cache.
sql/sp_cache.h:
  Declare sp_cache_version().
sql/sql_prepare.cc:
  Keep track of stored functions cache version, and invalidate
  the statement if it changed between prepared statement
  prepare and execute (and the statement actually uses stored routines).
