6da93b223b Bug#47280 - strange results from count(*) with order by multiple
columns without where/group
                     
Simple SELECT with implicit grouping used to return many rows if
the query was ordered by the aggregated column in the SELECT
list. This was incorrect because queries with implicit grouping
should only return a single record.
                              
The problem was that when JOIN:exec() decided if execution needed
to handle grouping, it was assumed that sum_func_count==0 meant
that there were no aggregate functions in the query. This
assumption was not correct in JOIN::exec() because the aggregate
functions might have been optimized away during JOIN::optimize().
                  
The reason why queries without ordering behaved correctly was
that sum_func_count is only recalculated if the optimizer chooses
to use temporary tables (which it does in the ordered case).
Hence, non-ordered queries were correctly treated as grouped.
                  
The fix for this bug was to remove the assumption that
sum_func_count==0 means that there is no need for grouping. This
was done by introducing variable "bool implicit_grouping" in the
JOIN object.

bc9f56a6c2 Bug #47123: Endless 100% CPU loop with STRAIGHT_JOIN
The problem was in incorrect handling of predicates involving 
NULL as a constant value by the range optimizer.  
 
For example, when creating a SEL_ARG node from a condition of 
the form "field < const" (which would normally result in the 
"NULL < field < const" SEL_ARG),  the special case when "const" 
is NULL was not taken into account, so "NULL < field < NULL" 
was produced for the "field < NULL" condition. 
 
As a result, SEL_ARG structures of this form could not be 
further optimized which in turn could lead to incorrectly 
constructed SEL_ARG trees. In particular, code assuming SEL_ARG 
structures to always form a sequence of ordered disjoint 
intervals could enter an infinite loop under some 
circumstances. 
 
Fixed by changing get_mm_leaf() so that for any sargable 
predicate except "<=>" involving NULL as a constant, "empty" 
SEL_ARG is returned, since such a predicate is always false.

  Added a test case for bug #47123.

662d836744 Fix for bug#47963: Wrong results when index is used
Problem: using null microsecond part (e.g. "YYYY-MM-DD HH:MM:SS.0000") 
in a WHERE condition may lead to wrong results due to improper
DATETIMEs comparison in some cases.

Fix: as we compare DATETIMEs as strings we must trim trailing 0's
in such cases.

64e89a7ed2 Bug#46448 trailing spaces are not ignored when user collation maps space != 0x20
In MySQL when the mapping for space is changed to something other than
0x20 by defining a different collation, then space is not ignored when
comparing two strings.

This was happening because the function that performs the comparison
of two strings while ignoring ending spaces, was comparing the collation
value of a space with the ascii value of the ' ' character. This should
be changed to do comparison between the collated values.

adbd70aa12 BUG#47073 - valgrind errs, corruption,failed repair of partition,
low myisam_sort_buffer_size

Repair by sort (default) or parallel repair of a MyISAM table
(doesn't matter partitioned or not) as well as bulk inserts
and enable indexes some times didn't failover to repair with
key cache.

The problem was that after unsuccessful attempt, data file was
closed. Whereas repair with key cache requires open data file.
Fixed by reopening data file.

Also fixed a valgrind warning, which may appear during repair
by sort or parallel repair with certain myisam_sort_buffer_size
number of rows and length of an index entry (very dependent).

mysql-test/r/myisam.result:
  A test case for BUG#47073.
mysql-test/t/myisam.test:

storage/myisam/ha_myisam.cc:
  Reverted fix for BUG25289. Not needed anymore.
storage/myisam/mi_check.c:
  Reopen data file, when repair by sort or parallel repair
  fails.
  
  When repair by sort is requested to rebuild data file, data file
  gets rebuilt while fixing first index. When rebuild is completed,
  info->dfile is pointing to temporary data file, original data file
  is closed.
  
  It may happen that repair has successfully fixed first index and
  rebuilt data file, but failed to fix second index. E.g.
  myisam_sort_buffer_size was big enough to fix first shorter index,
  but not enough to fix subsequent longer index.
  
  In this case we end up with info->dfile pointing to temporary file,
  which is removed and info->dfile is set to -1.
  
  Though repair by sort failed, the upper layer may still want to
  try repair with key cache. But it needs info->dfile pointing to
  valid data file.
storage/myisam/sort.c:
  When performing a copy of IO_CACHE structure, current_pos and
  current_end must be updated separatly to point to memory we're
  copying to (not to memory we're copying from).
  
  As t_file2 is always WRITE cache, proper members are write_pos
  and write_end accordingly.

798ce98340 Bug#43508: Renaming timestamp or date column triggers table copy
We set up DATE and TIMESTAMP differently in field-creation than we
did in field-MD creation (for CREATE). Admirably, ALTER TABLE
detected this and didn't damage any data, but it did initiate a
full copy/conversion, which we don't really need to do.

Now we describe Field and Create_field the same for those types.
As a result, ALTER TABLE that only changes meta-data (like a
field's name) no longer forces a data-copy when there needn't
be one.


mysql-test/r/alter_table.result:
  0 rows should be affected when a meta-data change is enough ALTER TABLE.
mysql-test/t/alter_table.test:
  add test-case: show that we don't do a full data-copy on ALTER TABLE
  when we don't need to.
sql/field.cc:
  Remove Field_str::compare_str_field_flags() (now in Field/Create_field as
  field_flags_are_binary().
  
  Correct some field-lengths!
sql/field.h:
  Clean-up: use defined constants rather than numeric literals for certain
  field-lengths.
  
  Add enquiry-functions binaryp() to classes Field and Create_field.
  This replaces field.cc's Field_str::compare_str_field_flags().

5ef9ec9d9e Bug#42846: wrong result returned for range scan when using
covering index
      
When two range predicates were combined under an OR
predicate, the algorithm tried to merge overlapping ranges
into one. But the case when a range overlapped several other
ranges was not handled. This lead to

1) ranges overlapping, which gave repeated results and 
2) a range that overlapped several other ranges was cut off.  

Fixed by 

1) Making sure that a range got an upper bound equal to the
next range with a greater minimum.
2) Removing a continue statement

  Part1: Previously, both endpoints from key2 were copied,
  which is not safe. Since ranges are processed in ascending
  order of minimum endpoints, it is safe to copy the minimum
  endpoint from key2 but not the maximum. The maximum may only
  be copied if there is no other range or the other range's
  minimum is greater than key2's maximum.

3185118e1a Fix for bug #42803: Field_bit does not have unsigned_flag field,
can lead to bad memory access

Problem: Field_bit is the only field which returns INT_RESULT
and doesn't have unsigned flag. As it's not a descendant of the 
Field_num, so using ((Field_num *) field_bit)->unsigned_flag may lead
to unpredictable results.

33cd911a16 Bug #44139: Table scan when NULL appears in IN clause
SELECT ... WHERE ... IN (NULL, ...) does full table scan,
even if the same query without the NULL uses efficient range scan.

The bugfix for the bug 18360 introduced an optimization:
if
  1) all right-hand arguments of the IN function are constants
  2) result types of all right argument items are compatible
     enough to use the same single comparison function to
     compare all of them to the left argument,

then

  we can convert the right-hand list of constant items to an array
  of equally-typed constant values for the further
  QUICK index access etc. (see Item_func_in::fix_length_and_dec()).

The Item_null constant item objects have STRING_RESULT
result types, so, as far as Item_func_in::fix_length_and_dec()
is aware of NULLs in the right list, this improvement efficiently
optimizes IN function calls with a mixed right list of NULLs and
string constants. However, the optimization doesn't affect mixed
lists of NULLs and integers, floats etc., because there is no
unique common comparator.


New optimization has been added to ignore the result type
of NULL constants in the static analysis of mixed right-hand lists.
This is safe, because at the execution phase we care about
presence of NULLs anyway.

1. The collect_cmp_types() function has been modified to optionally
   ignore NULL constants in the item list.
2. NULL-skipping code of the Item_func_in::fix_length_and_dec()
   function has been modified to work not only with in_string
   vectors but with in_vectors of other types.

The problem was that a hook used to detach client API handles

4d57b851a0 WL#4259 - Debug Sync Facility
Backport from 6.0 to 5.1.
Only those sync points are included, which are used in debug_sync.test.

  The Debug Sync Facility allows to place synchronization points
  in the code:
  
  open_tables(...)
  
  DEBUG_SYNC(thd, "after_open_tables");
  
  lock_tables(...)
  
  When activated, a sync point can
  
  - Send a signal and/or
  - Wait for a signal
  
  Nomenclature:
  
  - signal:            A value of a global variable that persists
                       until overwritten by a new signal. The global
                       variable can also be seen as a "signal post"
                       or "flag mast". Then the signal is what is
                       attached to the "signal post" or "flag mast".
  
  - send a signal:     Assign the value (the signal) to the global
                       variable ("set a flag") and broadcast a
                       global condition to wake those waiting for
                       a signal.
  
  - wait for a signal: Loop over waiting for the global condition until
                       the global value matches the wait-for signal.
  
  Please find more information in the top comment in debug_sync.cc
  or in the worklog entry.

8d3d35ea57 Bug#45567: Fast ALTER TABLE broken for enum and set
The problem was that appending values to the end of an existing
ENUM or SET column was being treated as table data modification,
preventing a immediately (fast) table alteration that occurs when
only table metadata is being modified.

The cause was twofold: adding a enumeration or set members to the 
end of the list of valid member values was not being considered
a "compatible" table alteration, and for SET columns, the check
was being done upon the max display length and not the underlying
(pack) length of the field.

The solution is to augment the function that checks wether two ENUM
or SET fields are compatible -- by comparing the pack lengths and
performing a limited comparison of the member values.

5f8bb5c507 Bug#47150 Assertion in Field_long::val_int() on MERGE + TRIGGER + multi-table UPDATE
The bug is not related to MERGE table or TRIGGER. More correct description
would be 'assertion on multi-table UPDATE + NATURAL JOIN + MERGEABLE VIEW'.
On PREPARE stage(see test case) we call mark_common_columns() func which
creates ON condition for NATURAL JOIN and sets appropriate
table read_set bitmaps for fields which are used in ON condition.
On EXECUTE stage mark_common_columns() is not called, we set
necessary read_set bitmaps in setup_conds(). But 'B.f1' field
is already processed and related item alredy fixed before
setup_conds() as updated field and setup_conds can not set
read_set bitmap because of that.
The fix is to set read_set bitmap for appropriate table field even
if Item_direct_view_ref item which represents a refernce to this field
is fixed.

4102363f37 Bug#43746: YACC return wrong query string when parse 'load data infile' sql statement
"load data" statements were written to the binlog as a mix of the original statement
and bits recreated from parse-info. This relied on implementation details and broke
with IGNORE_SPACES and versioned comments.

We now completely resynthesize the query for LOAD DATA for binlog (which among other
things normalizes them somewhat with regard to case, spaces, etc.).
We have already parsed the query properly, so we make use of that rather
than mix-and-match string literals and parsed items.
This should make us safe with regard to versioned comments, even those
spanning multiple tokens. Also no longer affected by IGNORE_SPACES.

sql/sql_load.cc:
  Completely rewrote write_execute_load_query_log_event() to synthesize the
  LOAD DATA statement wholesale, rather than piece it together from
  synthesized bits and literal excerpts from the original query. This
  will not only give us a nice, normalized statement (all uppercase,
  no excess spaces, etc.), it will also handle comments, including
  versioned comments right, which is certainly more than we can say
  about the previous incarnation.
sql/sql_yacc.yy:
  We're no longer assembling LOAD DATA statements from bodyparts of the
  original query, so some bookkeeping in the parser can go.

e86f08d054 Bug#35996: SELECT + SHOW VIEW should be enough to display
view definition

During SHOW CREATE VIEW there is no reason to 'anonymize'
errors that name objects that a user does not have access
to. Moreover it was inconsistently implemented. For example
base tables being referenced from a view appear to be ok,
but not views. The manual on the other hand is clear: If a
user has the privileges SELECT and SHOW VIEW, the view
definition is available to that user, period. The fix
changes the behavior to support the manual.

2dbe095c3a Bug#46958: Assertion in Diagnostics_area::set_ok_status,
trigger, merge table
            
The problem with break statements is that they have very
local effects. Hence a break statement within the inner loop
of a nested-loops join caused execution to proceed to the
next table even though a serious error occurred. The problem
was fixed by breaking out the inner loop into its own
method. The change empowers all errors to terminate the
execution.
            
The errors that will now halt multi-DELETE execution
altogether are 
  - triggers returning errors
  - handler errors
  - server being killed

1eef766534 Additional Fix for BUG#44030 - Error: (1500) Couldn't read the MAX(ID) autoinc
value from the index (PRIMARY)


With the fix for BUG#46760, we correctly flag the presence of row_type 
only when it's actually changed and enables the FAST ALTER TABLE which was
disabled with the BUG#39200.

So the changes made by BUG#46760 makes MySQL data dictionaries to be out of 
sync but they are handled already by InnoDB with this BUG#44030.

The test was originally written to handle this but we requested Innodb to
update the test as the data dictionaries were in sync after the fix for 
BUG#39200.

Adjusting the innodb-autoinc testcase as mentioned in the comments.

  compute the checksum.
