c758512a91 A fix and test case for Bug#9777 " Empty set returned by Prepared Statement when it
should return a non empty one"
(see comments for the changed files for details).


mysql-test/r/ps.result:
  A test case for Bug#9777: tests results fixed.
mysql-test/t/ps.test:
  A test case for Bug#9777
sql/item.cc:
  A fix for Bug#9777: when creating a constant item from within 
  Item_int_with_ref::new_item, create the item by value, not by name.
  This should work with prepared statements placeholders.
  Item_int_with_ref is a special optimization case used
   when we compare datetime constants with datetime value.
  Converting the item to integer early is OK as it is in line
  with the purpose of Item_int_with_ref - to speed up comparison by 
  using integers.
  Minor cleanups.

9fcda7fcc5 A fix and test case for Bug#9096 "select doesn't return all matched
records if prepared statements is used".
This fix changes equality evaluation method of basic constants from
by-name to by-value, thus effectively enabling use of parameter markers
in some optimizations (constants propagation, evaluation of possible
keys for query).


mysql-test/r/ps.result:
  Test results for the test case for Bug#9096
mysql-test/t/ps.test:
  A short test case for Bug#9096 "select doesn't return all matched records if
   prepared statements is used". The is enough to reproduce the
  glitch in update_ref_and_keys causing the bug to occur.
sql/item.cc:
  Implement by-value equality evaluation of basic constants.
  This is needed to work with Item_param values. Until now
  Item_param was compared with other items by its name, which is always "?".
  The bug at hand showed up when an integer
  constant was created from one parameter marker (with value 200887 and
   name "?") and then compared by-name with another parameter marker
  (with value 860 and name "?"). True returned by this comparison resulted
  in a wrong table access method used to evaluate the query.
  Implement Item_param methods needed to emulate "basic constant" mode at 
  full.
sql/item.h:
  Change declaration of basic_const_item(): now it also widens its 
  argument from const Item * to Item * if the argument is a basic constant.
  Declare eq() for all basic constatns, as long as now they 
  are compared by value, not by name. Each constant needs its own
  comparison method.
  Declarations of Item_param methods needed to fully emulate 
  a basic constant when parameter value is set.
sql/item_func.cc:
  Fix wrong casts.

146df30f79 Fix for BUG#7425.
The reported problems were due to two completely unrelated omissions.
1) The file sort procedure didn't correctly create the sort key in
   make_sortkey when the sortkey was an unsigned integer.
2) The name resolution procedure for column references inside a HAVING
   clause did not propagate the unsigned_flag of the resolved references.
This patch corrects both problems.

cd89ed9ab6 1. Item now uses my_charset_bin by default,
not default_charset_into. It fixes the
problem that in some cases numbers where
treated as CHAR(N), not as BINARY(N), e.g.
wrong 'charsetnr' when sent to the client side.
2. IFNULL didn't aggregate argument charsets
and collations, so IFNULL(1,'a') produced
a CHAR(N). Now produces a BINARY(N).
3. SELECT PROCEDURE ANALIZE now returns
BINARY columns, which is much better than it worked
previously: CHAR with the default character set.
But in the future it's worth to fix the fields
'Field_name' and 'Optimal_fieldtype' to use UTF8,
and 'Min_value' and 'Max_value' to inherit their charsets
from the original items. But it is not important,
and BINARY(N) is OK for now.
4. Tests were fixed accordingly. No new tests were
made, as the old onces cover everything.

In Item_ref::Item_ref set maybe_null (and other fields fix_fields sets) to be the

maybe_null was 0 always and this produced a bogus state where

5d9f7edd6d Fix for bug #6266 "Invalid DATETIME value is not handled properly".
In server we assume that datetime values stored in MYSQL_TIME struct
are normalized (and year is not greater than 9999), so we should 
perform range checks in all places then we convert something to
MYSQL_TIME.

  convinient.

c5e6941e75 1. When mixing NULL to a character string,
the result takes its charset/collation
attributes from the character string,
e.g.  SELECT func(NULL, _latin2'string')
now returns a latin2 result. This is
done by introducing a new derivation
(aka coercibility) level DERIVATION_IGNORABLE,
which is used with Item_null.
2. 'Pure' NULL is now BINARY(0), not CHAR(0).
I.e. NULL is now more typeless.

  Fix for the bug reported by Reggie: if character_set_connection
  is equal to character_set_client, placeholder's value is not converted

1d48aec228 A fix and test case for Bug#5987 "subselect in bool function
crashes server (prepared statements)": the bug was that all boolean
items always recovered its original arguments at statement cleanup 
stage.
This collided with Item_subselect::select_transformer, which tries to 
permanently change the item tree to use a transformed subselect instead of
original one.
So we had this call sequence for prepare:
mysql_stmt_prepare -> JOIN::prepare -> 
Item_subselect::fix_fields -> the item tree gets transformed ->
Item_bool_rowready_func2::cleanup, item tree is recovered to original
state, while it shouldn't have been;
mysql_stmt_execute -> attempts to execute a broken tree -> crash.
Now instead of bluntly recovering all arguments of bool functions in 
Item_bool_rowready_func2::cleanup, we recover only those
which were changed, and do it in one place.
There still would exist a possibility for a collision with subselect
tranformation, if permanent and temporary changes were performed at the 
same stage.
But fortunately subselect transformation is always done first, so it 
doesn't conflict with the optimization done by propogate_cond_constants.
Now we have: 
mysql_stmt_prepare -> JOIN::prepare -> subselect transformation 
permanently changes the tree -> cleanup doesn't recover anything, 
because nothing was registered for recovery.
mysql_stmt_execute -> JOIN::prepare (the tree is already transformed, 
so it doesn't change), JOIN::optimize -> 
propogate_cond_constants -> temporary changes the item tree 
with constants -> JOIN::execute -> cleanup -> 
the changes done by propogate_cond_constants are recovered, as
they were registered for recovery.

6aaccbcbf7 WL#1264 "Per-thread time zone support infrastructure".
Added basic per-thread time zone functionality (based on public
domain elsie-code). Now user can select current time zone
(from the list of time zones described in system tables).
All NOW-like functions honor this time zone, values of TIMESTAMP
type are interpreted as values in this time zone, so now
our TIMESTAMP type behaves similar to Oracle's TIMESTAMP WITH
LOCAL TIME ZONE (or proper PostgresSQL type).
  
WL#1266 "CONVERT_TZ() - basic time with time zone conversion 
function".
  
Fixed problems described in Bug #2336 (Different number of warnings 
when inserting bad datetime as string or as number). This required
reworking of datetime realted warning hadling (they now generated 
at Field object level not in conversion functions).
  
Optimization: Now Field class descendants use table->in_use member
instead of current_thd macro.


include/my_global.h:
  Added macro for reading of 32-bit ints stored in network order from
  unaligned memory location.
include/mysqld_error.h:
  Added error-code for invalid timestamp warning and error-code
  for wrong or unknown time zone specification.
libmysqld/Makefile.am:
  Added main per-thread time zone support file to libmysqld
libmysqld/lib_sql.cc:
  Added initialization of time zones infrastructure to embedded server.
mysql-test/r/connect.result:
  Updated test result since now mysql database contains more
  system tables.
mysql-test/r/date_formats.result:
  Now when truncation occurs during conversion to datetime value we are producing Warnings 
  instead of Notes. Also we are giving more clear warnings about this in some cases.
mysql-test/r/func_sapdb.result:
  New warnings about truncation occured during conversion to datetime value added due
  their better handling.
mysql-test/r/func_time.result:
  New warnings about truncation occured during conversion to datetime value added due
  their better handling.
mysql-test/r/select.result:
  New warnings about truncation occured during conversion to datetime value added due
  their better handling. Also tweaked test a bit to made it less ambigious for reader.
mysql-test/r/system_mysql_db.result:
  Updated test result because new system tables holding time zone descriptions were 
  added.
mysql-test/r/timezone.result:
  Updated timezone.test to use new system variable which shows system time zone.
  Added test of warning which is produced if someone tries to store non-existing (due 
  falling into spring time-gap) datetime value into TIMESTAMP field.
mysql-test/r/type_datetime.result:
  Separated and extended test of values and warnings produced for bad values stored in 
  DATETTIME fields.
mysql-test/r/type_time.result:
  Now we are producing more consistent warning when we are truncating datetime value while
  storing it in TIME field.
mysql-test/r/type_timestamp.result:
  Separated and extended test of values and warnings produced for bad
  values stored in TIMESTAMP fields.
mysql-test/t/select.test:
  Updated test to make it less ambigous for reader.
mysql-test/t/timezone.test:
  Updated timezone.test to use new system variable which shows system time zone.
  Added test of warning which is produced if someone tries to store non-existing (due 
  falling into spring time-gap) datetime value into TIMESTAMP field.
mysql-test/t/type_datetime.test:
  Separated and extended test of values and warnings produced for bad
  values stored in DATETTIME fields.
mysql-test/t/type_timestamp.test:
  Separated and extended test of values and warnings produced for bad
  values stored in TIMESTAMP fields.
scripts/mysql_create_system_tables.sh:
  Added creation of tables with time zone descriptions.
  Also added descriptions of time zones used in tests.
scripts/mysql_fix_privilege_tables.sql:
  Added mysql.time_zone* tables family.
sql/Makefile.am:
  Added files implementing time zone support to server, also added
  rules for building of mysql_tzinfo_to_sql converter and test_time
  test.
sql/field.cc:
  Now we are using per-thread time zone for TIMESTAMP <-> whatever conversion.
  Fixed generation of warnings for datetime types (DATETIME/TIMESTAMP/DATE/...) and
  any other Field to datetime conversion (now we are generating warnings no in lower
  level functions like in str_to_TIME() but in Field methods. This allows generate
  better and more consistent warnings and to reuse code of str_to_TIME() outside of
  server).
  
  Added 3rd parameter to set_warning() method to be able to not increment cut fields
  but still produce a warning. Also added set_datetime_warning() family of auxiliary 
  methods which allow easier generate datetime related warnings.
  Also replaced occurences of current_thd with table->in_use member, added
  asserts for catching all places there we need to set table->in_use
  accordingly. Renamed fix_datetime() function to number_to_TIME() and
  moved it to sql/time.cc there it fits better.
sql/field.h:
  Added comment about places where we can use table->in_use member
  instead of current_thd.
  Added 3rd parameter to Field::set_warning() method and set_datetime_warning()
  family of methods.
sql/field_conv.cc:
  Field::set_warning() method with 2 arguments was replaced with more 
  generic set_warning() method with 3 arguments.
sql/ha_berkeley.cc:
  Now we set table->in_use for temporary tables so we have to use
  table->tmp_table for checking if table is temporary.
sql/item.cc:
  Replaced calls to str_to_time() and str_to_TIME() funcs with their warning
  generating analogs.
sql/item_create.cc:
  Added creation of CONVERT_TZ function as FUNC_ARG3.
sql/item_create.h:
  Added creation of CONVERT_TZ function as FUNC_ARG3.
sql/item_timefunc.cc:
  Added support of per-thread time zone to NOW-like and FROM_UNIXTIME,
  UNIX_TIMESTAMP functions. 
  Added support for CONVERT_TZ function.
  Removed call to str_to_timestamp function which caused non-optimal
  behavior in certain cases. Replaced calls to str_to_time() function 
  with its warning generating analog.
sql/item_timefunc.h:
  Added support of per-thread time zone to NOW-like and
  FROM_UNIXTIME, UNIX_TIMESTAMP functions.
  Added support of CONVERT_TZ function.
sql/lex.h:
  Added support of CONVERT_TZ function.
sql/log.cc:
  Added support for replication of statements depending on time zone.
sql/mysql_priv.h:
  Now including headers with per-thread time zone support functions
  and classes. Added portable replacement of time_t - my_time_t type. 
  Added time zone as one of query distinguishing parameters for
  query cache. 
  Fixed declarations of str_to_TIME, str_to_time and 
  my_system_gmt_sec (former my_gmt_sec) since now they have one more
  out parameter which informs about wrong datetime value or data 
  truncation during conversion.
  Added warning generating version of str_to_TIME() and str_to_time()
  functions.
  Thrown away str_to_datetime/timestamp functions since they are not
  needed any longer. Added number_to_TIME function.
sql/mysqld.cc:
  Added per-thread time zone support initialization.
  Added new startup parameter --default-time-zone.
sql/set_var.cc:
  Added support for per-thread time_zone variable.
  Renamed old timezone variable to system_time_zone.
sql/set_var.h:
  Added support for per-thread time_zone variable.

  normalisation from former my_gmt_sec() since it was not working 
  and not used anywhere now, but breaks parameter constness, added
  to this function generation of warning if we are falling in spring 
  time-gap. Removed str_to_timestamp and str_to_datetime functions 
  which are no longer used. Moved fix_datetime function from
  sql/field.cc to this file as number_to_TIME() function. Added
  out parameter for str_to_TIME and str_to_time functions which
  indicates if value was truncated during conversion, removed direct 
  generation of warnings from this functions.)

27eda71204 Proposed fix for Bug#4026 "Microseconds part of TIME/DATETIME types
is broken (prepared statements)": fixed date handling in many places 
of prepared statements code.


libmysql/libmysql.c:
  Fix for Bug#4026:
  - now buffer_length is defined for any buffer type. Network buffer 
    preallocation cleaned up.
  - added constants for maximum buffer sizes necessary for MYSQL_TYPE_DATE,
    MYSQL_TYPE_TIME, MYSQL_TYPE_DATETIME types.
  - TIME/DATETIME packing/unpacking functions fixed 
  - now result set metadata is always updated from fields sent to COM_EXECUTE.
    This is necessary to make 'SELECT ?' queries work without conversions.
sql/item.cc:
  - added implementatoin of Item_param::get_date
sql/item.h:
  - added enum_field_types Item_param::param_type. First step for proper
    handling of placeholders.
  - added get_date() implementation to prevent date -> string -> date 
    conversions when MYSQL_TYPE_DATE/DATETIME parameter is used in temporal 
    context.
sql/protocol.cc:
  Fix for Bug#4026:
  - PACKET_BUFFET_EXTRA_ALLOC -> PACKET_BUFFER_EXTRA_ALLOC.
    The define itself was moved to .cc as it's used only in protocol.cc
  - fixed Protocol_prep::store_time() call.
sql/protocol.h:
  - PACKET_BUFFER_EXTRA_ALLOC moved to protocol.cc
sql/sql_prepare.cc:
  Fix for Bug#4026:
  - MYSQL_TYPE_TIME/DATETIME handling fixed.
  - added initialization for Item_param::param_type in 
    setup_one_conversion_function
tests/client_test.c:
  Test case for Bug#4026

093d62922b Support for character set conversion in binary protocol: another go
after Monty's review.
- Item_param was rewritten.
- it turns out that we can't convert string data to character set of
  connection on the fly, because they first should be written to the binary
  log.
  To support efficient conversion we need to rewrite prepared statements
  binlogging code first.


include/my_global.h:
  Macro swap(a, b, c) was renamed to resolve name conflict with
  String::swap() method.
include/my_sys.h:
  Added declaration of escape_string_for_mysql()
include/mysql_com.h:
  Removed and moved back: a macro which is visible to libmysql user but
  has sence only in prepared statement protocol implementation.
isam/_search.c:
  swap -> swap_variables
isam/test2.c:
  swap -> swap_variables
libmysql/libmysql.c:
  - sub_escape_string moved to mysys/charset.c to be visible in sql/
  - few cleanups
myisam/mi_test2.c:
  swap -> swap_variables
mysys/charset.c:
  sub_escape_string was moved from libmysql.c to be able to use it in sql/
  code.
mysys/my_chsize.c:
  rename: swap -> swap_variables
mysys/my_compress.c:
  swap -> swap_variables
mysys/my_handler.c:
  swap -> swap_variables
sql/field.cc:
  Field::store_time refactored to use TIME_to_string function from time.cc
sql/item.cc:
  New implementation of Item_param class:
  added support for character sets conversion.
sql/item.h:
  Item_param:
  - 'state' member introduced instead of many boolean variables.
  - put ltime, int_value and real_value into union to save space.
  - remove unimplemented members
  - set_value renamed to set_str
sql/item_timefunc.cc:
  Refactored to use functions from time.cc
sql/lock.cc:
  rename: swap -> swap_variables
sql/mysql_priv.h:
  - added declarations for TIME_to_ulonglong_*, TIME_to_string functions
  - const specifiers for make_date, make_time, make_datetime arguments
sql/opt_range.cc:
  rename: swap -> swap_variables
sql/protocol.cc:
  - added character set conversion support to binary protocol.
  - Protocol::convert changed to point at shared buffer in THD.
    This lets us use one convert buffer for binary and simple protocol.
    The same buffer is used for client->server conversions in prepared
    statements code.
  - string conversion code refactored to Protocol::store_string_aux function.
  - few more comments
sql/protocol.h:
  - Protocol::convert now points at THD::convert_buffer: we want to share one
    buffer between all protocol implementations.
sql/sql_class.cc:
  - implementation of THD::convert_string using THD::convert_buffer
    (conversion of strings allocated in the system heap).
sql/sql_class.h:
  - THD::convert_buffer is shared between THD and network Protocols and
    used for character set conversion of strings.
  - new function to convert String object from one charset to another using
    THD::convert_buffer
sql/sql_insert.cc:
  A little fix in a comment.
sql/sql_parse.cc:
  Shrink convert buffer in the end of each statement.
sql/sql_prepare.cc:
    Many changes:
  - static specifier for set_param_* family of functions.
  - FIELD_TYPE -> MYSQL_TYPE
  - added set_param_binary as handler for BLOB types.
  - added character set support
  - added support for param typecode in mysql_stmt_get_longdata
    (mysql_stmt_send_long_data handler)
  - changes in Item_param deployed
  - few cleanups
sql/sql_select.cc:
  rename: swap -> swap_variables
sql/sql_string.cc:
  - String::append rewritten to support character set conversion for
  single-byte encodings.
  - added String::swap method to efficiently exchange two string objects.
sql/sql_string.h:
  Declraration for String::swap().
sql/time.cc:
  - function TIME_to_string to convert TIME to String in default MySQL format
  - family of functions TIME_to_ulonglong_*
tests/client_test.c:
  Test for support for character set conversions in prepared statements
  (binary and text data).

6ca757544b Fix for remaining issues described in Bug #1664
"mysql_send_long_data() API call is completely broken".

Now we are resetting some members (long_data_supplied/null_value...) of Item_param to its 
initial state after each execution of prepared statement. We also manipulating 
Item_param::maybe_null/null_value only via Item_param::set_* setters which makes code a bit 
more robust.


sql/item.cc:
  Now we are assuming that Item_param may be NULL until we know this fact exactly.
  Added non-empty implementation of Item_param::reset() method which should be used
  for restoring Item_param state after each statment execution. (We need to clear 
  long_data_supplied flag, we also clear some other Item_param members here since it
  makes code simpler.)
sql/item.h:
  Now Item_param::reset() method really does something.
sql/sql_prepare.cc:
  Now we are calling Item_param::reset() for each parameter after execution for resetting Item_param
  to initial state. So we no longer don't need Prepared_statement::long_data_flag. We also 
  set Item_param::null_value/maybe_null value in Item_param::set_* and reset() methods 
  instead of doing it explicitly in insert_params_* functions (this by the way lowers 
  probability that we will forget to update one of such functions).
tests/client_test.c:
  Added test for Bug#1664 "mysql_send_long_data() API call is broken".
