a073ee45c2 Bug #43414 Parenthesis (and other) warnings compiling MySQL
with gcc 4.3.2
      
Compiling MySQL with gcc 4.3.2 and later produces a number of 
warnings, many of which are new with the recent compiler
versions.
      
This bug will be resolved in more than one patch to limit the
size of changesets. This is the first patch, fixing a number 
of the warnings, predominantly "suggest using parentheses 
around && in ||", and empty for and while bodies.

f0352e346a Bug#38469 invalid memory read and/or crash with utf8 text field, stored procedure, uservar
A stored procedure involving substrings could crash the server on certain
platforms because of invalid memory reads.
          
During storing the new blob-field value, the cached value's address range
overlapped that of the new field value. This caused problems when the 
cached value storage was reallocated to provide access for a new 
characater set representation. The patch checks the address ranges, and if
they overlap, the new field value is copied to a new storage before it is
converted to the new character set.

  The source and destination address ranges of a character conversion must not overlap or the 'from' address will be invalidated as the temporary value-

54a59681d6 Bug #37799: SELECT with a BIT column in WHERE clause
returns unexpected result

If:
  1. a table has a not nullable BIT column c1 with a length
     shorter than 8 bits and some additional not nullable
     columns c2 etc, and
  2. the WHERE clause is like: (c1 = constant) AND c2 ...,
the SELECT query returns unexpected result set.


The server stores BIT columns in a tricky way to save disk
space: if column's bit length is not divisible by 8, the
server places reminder bits among the null bits at the start
of a record. The rest bytes are stored in the record itself,
and Field::ptr points to these rest bytes.

However if a bit length of the whole column is less than 8,
there are no remaining bytes, and there is nothing to store in
the record at its regular place. In this case Field::ptr points
to bytes actually occupied by the next column in a record.
If both columns (BIT and the next column) are NOT NULL,
the Field::eq function incorrectly deduces that this is the
same column, so query transformation/equal item elimination
code (see build_equal_items_for_cond) may mix these columns
and damage conditions containing references to them.


mysql-test/r/type_bit.result:
  Added test case for bug #37799.
mysql-test/t/type_bit.test:
  Added test case for bug #37799.
sql/field.h:
  1. The Field::eq function has been modified to take types of
  comparing columns into account to distinguish between BIT and
  not BIT columns referencing the same bytes in a record.
  
  2. Unnecessary type comparison has been removed from the
  Field_bit::eq function (moved to Field::eq).

e04dfffb59 Bug#38296 (low memory crash with many conditions in a query)
This fix is for 5.0 only : back porting the 6.0 patch manually

The parser code in sql/sql_yacc.yy needs to be more robust to out of
memory conditions, so that when parsing a query fails due to OOM,
the thread gracefully returns an error.

Before this fix, a new/alloc returning NULL could:
- cause a crash, if dereferencing the NULL pointer,
- produce a corrupted parsed tree, containing NULL nodes,
- alter the semantic of a query, by silently dropping token values or nodes

With this fix:
- C++ constructors are *not* executed with a NULL "this" pointer
when operator new fails.
This is achieved by declaring "operator new" with a "throw ()" clause,
so that a failed new gracefully returns NULL on OOM conditions.

- calls to new/alloc are tested for a NULL result,

- The thread diagnostic area is set to an error status when OOM occurs.
This ensures that a request failing in the server properly returns an
ER_OUT_OF_RESOURCES error to the client.

- OOM conditions cause the parser to stop immediately (MYSQL_YYABORT).
This prevents causing further crashes when using a partially built parsed
tree in further rules in the parser.

No test scripts are provided, since automating OOM failures is not
instrumented in the server.
Tested under the debugger, to verify that an error in alloc_root cause the
thread to returns gracefully all the way to the client application, with
an ER_OUT_OF_RESOURCES error.

5a1b7ddb68 Partial rollback of fix for bug #30059: End-space truncation is inconsistent
or incorrect.

For better conformance with standard, truncation procedure of CHAR columns
has been changed to ignore truncation of trailing whitespace characters
(note has been removed).

Finally, for columns with non-binary charsets:

1. CHAR(N) columns silently ignore trailing whitespace truncation;
2. VARCHAR and TEXT columns issue Note about truncation.

BLOBs and other columns with BINARY charset are unaffected.

  The Field_string::store method has been changed to
  ignore trailing whitespace truncation (CHAR column
  type).

3891d43617 Fixed bug#30059.
Server handles truncation for assignment of too-long values
into CHAR/VARCHAR/TEXT columns in a different ways when the
truncated characters are spaces:
1. CHAR(N) columns silently ignore end-space truncation;
2. TEXT columns post a truncation warning/error in the
   non-strict/strict mode.
3. VARCHAR columns always post a truncation note in
   any mode.

Space truncation processing has been synchronised over
CHAR/VARCHAR/TEXT columns: current behavior of VARCHAR
columns has been propagated as standard.

Binary-encoded string/BLOB columns are not affected.

  Field_longstr::report_if_important_data method.
  
  The Field_string::store and the Field_blob::store
  methods was synchronized with the Field_varstring::store
  method.
  Changes:
  1. to CHAR(N): posting of space truncation note has been added
     in both (strict and non-strict) modes;
  2. to BLOBs: a check for space truncation has been added,
     a warning in the non-strict mode and an error message in
     the strict mode have been replaced with a truncation note.
  
  Similar parts of Field_string::store, Field_blob::store and
  Field_varstring::store have been moved to the
  Field_longstr::report_if_important_data method.
sql/field.h:
  Fixed bug#30059.
  The Field_longstr::report_if_important_data method has been declared.

94f75ffcce Bug#32848: Data type conversion bug in union subselects in MySQL 5.0.38
There were two problems when inferring the correct field types resulting from
UNION queries.
- If the type is NULL for all corresponding fields in the UNION, the resulting 
  type would be NULL, while the type is BINARY(0) if there is just a single 
  SELECT NULL.
- If one SELECT in the UNION uses a subselect, a temporary table is created
  to represent the subselect, and the result type defaults to a STRING type,
  hiding the fact that the type was unknown(just a NULL value).
Fixed by remembering whenever a field was created from a NULL value and pass
type NULL to the type coercion if that is the case, and creating a string field
as result of UNION only if the type would otherwise be NULL.

08b256f9df Bug#31990: MINUTE() and SECOND() return bogus results when used on a DATE
HOUR(), MINUTE(), ... returned spurious results when used on a DATE-cast.
This happened because DATE-cast object did not overload get_time() method
in superclass Item. The default method was inappropriate here and
misinterpreted the data.

on NULL input, 0 otherwise. This coincides with the way DATE-columns
behave.

aec287fd67 Bug #30825: Problems when putting a non-spatial index on a GIS column
Fixed the usage of spatial data (and Point in specific) with 
 non-spatial indexes.
 Several problems :
   - The length of the Point class was not updated to include the 
     spatial reference system identifier. Fixed by increasing with 4 
     bytes.
   - The storage length of the spatial columns was not accounting for
     the length that is prepended to it. Fixed by treating the 
     spatial data columns as blobs (and thus increasing the storage
     length)
   - When creating the key image for comparison in index read wrong
     key image was created (the one needed for and r-tree search,
     not the one for b-tree/other search). Fixed by treating the
     spatial data columns as blobs (and creating the correct kind of
     image based on the index type).

18310fabf4 Bug#28763: Selecting geometry fields in UNION caused server crash.
This bug was introduced by the fix for the bug#27300. In this fix a section
of code was added to the Item::tmp_table_field_from_field_type method.
This section intended to create Field_geom fields for the Item_geometry_func
class and its descendants. In order to get the geometry type of the current
item it casted "this" to the Item_geometry_func* type. But the
Item::tmp_table_field_from_field_type method is also used for creation of
fields for UNION and in this case this method is called for an object of the
Item_type_holder class and the cast to the Item_geometry_func* type causes 
a server crash.

Now the Item::tmp_table_field_from_field_type method correctly works when it's
called for both the Item_type_holder and the Item_geometry_func classes.
The new geometry_type variable is added to the Item_type_holder class.
The new method called get_geometry_type is added to the Item_field
and the Field classes. It returns geometry type from the field for the
Item_field and the Field_geom classes and fails an assert for other Field
descendants.


sql/field.h:

e3af3c2127 Fix for bug #28121 "INSERT or UPDATE into DOUBLE(200,0) field being truncated to 31 digits"
When storing a large number to a FLOAT or DOUBLE field with fixed length, it could be incorrectly truncated if the field's length was greater than 31.

This patch also does some code cleanups to be able to reuse code which is common between Field_float::store() and Field_double::store().


include/m_string.h:
  Added declarations for log_10 and log_01 from strtod.c
mysql-test/r/type_float.result:
  Added the testcase for bug #28121 "INSERT or UPDATE into DOUBLE(200,0) field being truncated to 31 digits"
mysql-test/t/type_float.test:
  Added the testcase for bug #28121 "INSERT or UPDATE into DOUBLE(200,0) field being truncated to 31 digits"
sql/field.cc:
  Moved common code from Field_float::store() and Field_double:store() to Field_real::truncate()
  Fixed the algorithm to not truncate large input numbers if the field length is greater than 31.
  Fixed rounding to not depend on FLT_MAX/DBL_MAX constants.
sql/field.h:
  Moved not_fixed member from Field_double to Field_real to allow code reuse between Field_float::store() and Field_double::store()
  Added truncate() method to Field_real which is used by both Field_float and Field_double
sql/init.cc:
  log_10[] and log_01[] are now defined as statical arrays in strtod.c, no need to pre-computed them.
sql/item_cmpfunc.cc:
  log_01[] now starts from 1e0, not from 1e-1 for consistency.
sql/mysql_priv.h:
  Moved log_10[] and log_01[] from mysqld.cc to libmystrings.
sql/mysqld.cc:
  Moved log_10[] and log_01[] from mysqld.cc to libmystrings.
strings/strtod.c:
  Define and use log_10[] and log_01[] as static arrays of constants instead of values pre-computed at startup.

aa32336198 Bug #24791: Union with AVG-groups generates wrong results
The problem in this bug is when we create temporary tables. When
temporary tables are created for unions, there is some 
inferrence being carried out regarding the type of the column.
Whenever this column type is inferred to be REAL (i.e. FLOAT or
DOUBLE), MySQL will always try to maintain exact precision, and
if that is not possible (there are hardware limits, since FLOAT
and DOUBLE are stored as approximate values) will switch to
using approximate values. The problem here is that at this point
the information about number of significant digits is not 
available. Furthermore, the number of significant digits should
be increased for the AVG function, however, this was not properly 
handled. There are 4 parts to the problem:

#1: DOUBLE and FLOAT fields don't display their proper display 
lengths in max_display_length(). This is hard-coded as 53 for 
DOUBLE and 24 for FLOAT. Now changed to instead return the 
field_length.

#2: Type holders for temporary tables do not preserve the 
max_length of the Item's from which they are created, and is 
instead reverted to the 53 and 24 from above. This causes 
*all* fields to get non-fixed significant digits.

#3: AVG function does not update max_length (display length)
when updating number of decimals.

#4: The function that switches to non-fixed number of 
significant digits should use DBL_DIG + 2 or FLT_DIG + 2 as 
cut-off values (Since fixed precision does not use the 'e' 
notation)

Of these points, #1 is the controversial one, but this 
change is preferred and has been cleared with Monty. The 
function causes quite a few unit tests to blow up and they had
to b changed, but each one is annotated and motivated. We 
frequently see the magical 53 and 24 give way to more relevant
numbers.


mysql-test/r/create.result:
  bug#24791

  changed test result
  
  delta 1: field was originally declared as DOUBLE with no display
  length, so the hardware maximum is chosen rather than 53.
  
  delta 2: fields exceed the maximum precision and thus switch to
  non-fixed significant digits
  
  delta 3: Same as above, number of decmals and significant digits
  was not specified when t3 was created.

  Test case
sql/field.h:
  bug#24791
  
  The method max_display_length is reimplemented as
  
  uint32 max_display_length() { return field_length; }
  
  in Field_double and Field_float. Since all subclasses of 
  Field_real now have the same implementation of this method, the
  implementation has been moved up the hierarchy to Field_real.
sql/item.cc:
  bug#24791
  
  We switch to a non-fixed number of significant digits
  (by setting decimals=NOT_FIXED_DECIMAL) if the calculated 
  display length is greater than the display length of a value 
  with the maximum precision. These values differ for double and 
  float, obviously.
sql/item_sum.cc:
  bug#24791
  
  We must increase the display length accordinly whenever we 
  change number of decimal places.

INSERT DELAYED inserts garbage for BIT columns.

When delayed thread clones TABLE object, it didn't adjusted bit_ptr

c35ceeca9e Bug #22344: InnoDB keys act strange on datetime vs timestamp comparison
Ignoring error codes from type conversion allows default (wrong) values to
 go unnoticed in the formation of index search conditions.
 Fixed by correctly checking for conversion errors.

faad73550c fix for bug #19690: ORDER BY eliminates rows from the result
Depending on the queries we use different data processing methods
and can lose some data in case of double (and decimal in 4.1) fields.

The fix consists of two parts:
1. double comparison changed, now double a is equal to double b 
if (a-b) is less than 5*0.1^(1 + max(a->decimals, b->decimals)). 
For example, if a->decimals==1, b->decimals==2, a==b if (a-b)<0.005
2. if we use a temporary table, store double values there as is 
to avoid any data conversion (rounding).


mysql-test/r/type_float.result:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - test result
mysql-test/t/type_float.test:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - test case
sql/field.cc:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - use not_fixed flag instead of dec to check bounds.
sql/field.h:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - Field_Double::not_fixed flag introduced, which is set if dec == NOT_FIXED_DEC
      and is used in the ::store() to check bounds. 
    - new constructor introduced (with not_fixed_arg parameter).
sql/init.cc:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - fill log_01[] array with 0.1 powers.
sql/item_cmpfunc.cc:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - compare_real_fixed() and compare_e_real_fixed() introduced,
      they consider double a == double b if a-b is less than 'precision',
      'precision' is set to 5*0.1^(1 + max(a->decimals, b->decimals)), 
      for example, if a->decimals==1, b->decimals==2, 'precision' is 0.005
    - use the above functions if both arguments are fixed.
sql/item_cmpfunc.h:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - Arg_comparator::presision introduced.
    - Arg_comparator::compare_real_fixed(), Arg_comparator::compare_e_real_fixed() introduced.
sql/mysql_priv.h:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - log_01 array of 0.1 powers added.
sql/mysqld.cc:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - log_01 array of 0.1 powers added.
sql/sql_select.cc:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - if we create double field in a temporary table, set not_fixed flag
      (use proper constructor) to avoid data conversion 
      in the Field_double::store(). Otherwise we can lose some data.
