12c42b980a Fix for BUG#11755168 '46895: test "outfile_loaddata" fails (reproducible)'. 
In sql_class.cc, 'row_count', of type 'ha_rows', was used as last argument for
ER_TRUNCATED_WRONG_VALUE_FOR_FIELD which is
"Incorrect %-.32s value: '%-.128s' for column '%.192s' at row %ld".
So 'ha_rows' was used as 'long'.
On SPARC32 Solaris builds, 'long' is 4 bytes and 'ha_rows' is 'longlong' i.e. 8 bytes.
So the printf-like code was reading only the first 4 bytes.
Because the CPU is big-endian, 1LL is 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01
so the first four bytes yield 0. So the warning message had "row 0" instead of
"row 1" in test outfile_loaddata.test:
-Warning	1366	Incorrect string value: '\xE1\xE2\xF7' for column 'b' at row 1
+Warning	1366	Incorrect string value: '\xE1\xE2\xF7' for column 'b' at row 0

All error-messaging functions which internally invoke some printf-life function
are potential candidate for such mistakes.
One apparently easy way to catch such mistakes is to use
ATTRIBUTE_FORMAT (from my_attribute.h).
But this works only when call site has both:
a) the format as a string literal
b) the types of arguments.
So:
  func(ER(ER_BLAH), 10);
will silently not be checked, because ER(ER_BLAH) is not known at
compile time (it is known at run-time, and depends on the chosen
language).
And
  func("%s", a va_list argument);
has the same problem, as the *real* type of arguments is not
known at this site at compile time (it's known in some caller).
Moreover,
  func(ER(ER_BLAH));
though possibly correct (if ER(ER_BLAH) has no '%' markers), will not
compile (gcc says "error: format not a string literal and no format
arguments").

Consequences:
1) ATTRIBUTE_FORMAT is here added only to functions which in practice
take "string literal" formats: "my_error_reporter" and "print_admin_msg".
2) it cannot be added to the other functions: my_error(),
push_warning_printf(), Table_check_intact::report_error(),
general_log_print().

To do a one-time check of functions listed in (2), the following
"static code analysis" has been done:
1) replace
  my_error(ER_xxx, arguments for substitution in format)
with the equivalent
  my_printf_error(ER_xxx,ER(ER_xxx), arguments for substitution in
format),
so that we have ER(ER_xxx) and the arguments *in the same call site*
2) add ATTRIBUTE_FORMAT to push_warning_printf(),
Table_check_intact::report_error(), general_log_print()
3) replace ER(xxx) with the hard-coded English text found in
errmsg.txt (like: ER(ER_UNKNOWN_ERROR) is replaced with
"Unknown error"), so that a call site has the format as string literal
4) this way, ATTRIBUTE_FORMAT can effectively do its job
5) compile, fix errors detected by ATTRIBUTE_FORMAT
6) revert steps 1-2-3.
The present patch has no compiler error when submitted again to the
static code analysis above.
It cannot catch all problems though: see Field::set_warning(), in
which a call to push_warning_printf() has a variable error
(thus, not replacable by a string literal); I checked set_warning() calls
by hand though.

See also WL 5883 for one proposal to avoid such bugs from appearing
again in the future.

The issues fixed in the patch are:
a) mismatch in types (like 'int' passed to '%ld')
b) more arguments passed than specified in the format.
This patch resolves mismatches by changing the type/number of arguments,
not by changing error messages of sql/share/errmsg.txt. The latter would be wrong,
per the following old rule: errmsg.txt must be as stable as possible; no insertions
or deletions of messages, no changes of type or number of printf-like format specifiers,
are allowed, as long as the change impacts a message already released in a GA version.
If this rule is not followed:
- Connectors, which use error message numbers, will be confused (by insertions/deletions
of messages)
- using errmsg.sys of MySQL 5.1.n with mysqld of MySQL 5.1.(n+1)
could produce wrong messages or crash; such usage can easily happen if
installing 5.1.(n+1) while /etc/my.cnf still has --language=/path/to/5.1.n/xxx;
or if copying mysqld from 5.1.(n+1) into a 5.1.n installation.
When fixing b), I have verified that the superfluous arguments were not used in the format
in the first 5.1 GA (5.1.30 'bteam@astra04-20081114162938-z8mctjp6st27uobm').
Had they been used, then passing them today, even if the message doesn't use them
anymore, would have been necessary, as explained above.

include/my_getopt.h:
  this function pointer is used only with "string literal" formats, so we can add
  ATTRIBUTE_FORMAT.
mysql-test/collections/default.experimental:
  test should pass now
sql/derror.cc:
  by having a format as string literal, ATTRIBUTE_FORMAT check becomes effective.
sql/events.cc:
  Change justified by the following excerpt from sql/share/errmsg.txt:
  ER_EVENT_SAME_NAME
          eng "Same old and new event name"
  ER_EVENT_SET_VAR_ERROR
          eng "Error during starting/stopping of the scheduler. Error code %u"

sql/ha_ndbcluster_binlog.cc:
  Too many arguments for:
  ER_GET_ERRMSG  
          eng "Got error %d '%-.100s' from %s"
  Patch by Jonas Oreland.
sql/ha_partition.cc:
  print_admin_msg() is used only with a literal as format, so ATTRIBUTE_FORMAT
  works.
sql/handler.cc:

* Item_func_coalesce calculates decimals for temporal types
* no precision for TIME/DATETIME in CAST means 0, not NOT_FIXED_DEC
* addtime/timediff calculate decimals from arguments (not NOT_FIXED_DEC)

e3dee8a7fd Bug#57737 Character sets: search fails with like, contraction, index 
Problem: LIKE over an indexed column optimized away good results,
because my_like_range_utf32/utf16 returned wrong ranges for contractions.
Contraction related code was missing in my_like_range_utf32/utf16,
but did exist in my_like_range_ucs2/utf8.
It was forgotten in utf32/utf16 versions (during mysql-6.0 push/revert mess).

Fix:
The patch removes individual functions my_like_range_ucs2,
my_like_range_utf16, my_like_range_utf32 and introduces a single function
my_like_range_generic() instead. The new function handles contractions
correctly. It can handle any character set with cs->min_sort_char and
cs->max_sort_char represented in Unicode code points.

added:
  @ mysql-test/include/ctype_czech.inc
  @ mysql-test/include/ctype_like_ignorable.inc
  @ mysql-test/r/ctype_like_range.result
  @ mysql-test/t/ctype_like_range.test
  Adding tests


modified:

  @ include/m_ctype.h
  - Adding helper functions for contractions.
  - Prototypes: removing ucs2,utf16,utf32 functions, adding generic function.
  @ mysql-test/r/ctype_uca.result
  @ mysql-test/r/ctype_utf16_uca.result
  @ mysql-test/r/ctype_utf32_uca.result
  @ mysql-test/t/ctype_uca.test
  @ mysql-test/t/ctype_utf16_uca.test
  @ mysql-test/t/ctype_utf32_uca.test
  - Adding tests.

  @ strings/ctype-mb.c
  - Pad function did not put the last character.
  - Implementing my_like_range_generic() - an universal replacement
    for three separate functions
    my_like_range_ucs2(), my_like_range_utf16() and my_like_range_utf32(),
    with correct contraction handling.

  @ strings/ctype-ucs2.c
  - my_fill_mb2 did not put the high byte, as previously
    it was used to put only characters in ASCII range.
    Now it puts high byte as well
    (needed to pupulate cs->max_sort_char correctly).
  - Adding DBUG_ASSERT()
  - Removing character set specific functions:
    my_like_range_ucs2(), my_like_range_utf16() and my_like_range_utf32().
  - Using my_like_range_generic() instead of the old functions.

  @ strings/ctype-uca.c
  - Using generic function instead of the old character set specific ones.

  @ sql/item_create.cc
  @ sql/item_strfunc.cc
  @ sql/item_strfunc.h
  - Adding SQL functions LIKE_RANGE_MIN and LIKE_RANGE_MAX,
    available only in debug build to make sure like_range()
    works correctly for all character sets and collations.

0eb26fdfa8 Bug#53445: Build with -Wall and fix warnings that it generates 
Apart strict-aliasing warnings, fix the remaining warnings
generated by GCC 4.4.4 -Wall and -Wextra flags.

One major source of warnings was the in-house function my_bcmp
which (unconventionally) took pointers to unsigned characters
as the byte sequences to be compared. Since my_bcmp and bcmp
are deprecated functions whose only difference with memcmp is
the return value, every use of the function is replaced with
memcmp as the special return value wasn't actually being used
by any caller.

There were also various other warnings, mostly due to type
mismatches, missing return values, missing prototypes, dead
code (unreachable) and ignored return values.

BUILD/SETUP.sh:
  Remove flags that are implied by -Wall and -Wextra.
  Do not warn about unused parameters in C++.
BUILD/check-cpu:
  Print only the compiler version instead of verbose banner.
  Although the option is gcc specific, the check was only
  being used for GCC specific checks anyway.
client/mysql.cc:
  bcmp is no longer defined.
client/mysqltest.cc:
  Pass a string to function expecting a format string.
  Replace use of bcmp with memcmp.
cmd-line-utils/readline/Makefile.am:
  Always define _GNU_SOURCE when compiling GNU readline.
  Required to make certain prototypes visible.
cmd-line-utils/readline/input.c:
  Condition for the code to be meaningful.
configure.in:
  Remove check for bcmp.
extra/comp_err.c:
  Use appropriate type.
extra/replace.c:
  Replace use of bcmp with memcmp.
extra/yassl/src/crypto_wrapper.cpp:
  Do not ignore the return value of fgets. Retrieve the file
  position if fgets succeed -- if it fails, the function will
  bail out and return a error.
extra/yassl/taocrypt/include/blowfish.hpp:
  Use a single array instead of accessing positions of the sbox_
  through a subscript to pbox_.
extra/yassl/taocrypt/include/runtime.hpp:
  One definition of such functions is enough.
extra/yassl/taocrypt/src/aes.cpp:
  Avoid potentially ambiguous conditions.
extra/yassl/taocrypt/src/algebra.cpp:
  Rename arguments to avoid shadowing related warnings.
extra/yassl/taocrypt/src/blowfish.cpp:
  Avoid potentially ambiguous conditions.
extra/yassl/taocrypt/src/integer.cpp:
  Do not define type within a anonymous union.
  Use a variable to return a value instead of
  leaving the result in a register -- compiler
  does not know the logic inside the asm.
extra/yassl/taocrypt/src/misc.cpp:
  Define handler for pure virtual functions.
  Remove unused code.
extra/yassl/taocrypt/src/twofish.cpp:
  Avoid potentially ambiguous conditions.
extra/yassl/testsuite/test.hpp:
  Function must have C language linkage.
include/m_string.h:
  Remove check which relied on bcmp being defined -- they weren't
  being used as bcmp is only visible when _BSD_SOURCE is defined.
include/my_bitmap.h:
  Remove bogus helpers which were used only in a few files and
  were causing warnings about dead code.
include/my_global.h:
  Due to G++ bug, always silence false-positive uninitialized
  variables warnings when compiling C++ code with G++.
  Remove bogus helper.
libmysql/Makefile.shared:
  Remove built-in implementation of bcmp.
mysql-test/lib/My/SafeProcess/safe_process.cc:
  Cast pid to largest possible type for a process identifier.
mysys/mf_loadpath.c:
  Leave space of the ending nul.

  Silence bogus uninitialized variable warning.
  Do not cast away the constant qualifier.
mysys/safemalloc.c:

mysys/thr_lock.c:

sql/field.cc:
  Replace bogus helper with a more appropriate logic which is
  used throughout the code.
sql/item.cc:
  Remove bogus logical condition which always evaluates to TRUE.
sql/item_create.cc:
  Simplify code to avoid signedness related warnings.
sql/log_event.cc:
  Replace use of bcmp with memcmp.
  No need to use helpers for simple bit operations.
sql/log_event_old.cc:
  Replace bmove_align with memcpy.
sql/mysqld.cc:
  Move use declaration of variable to the ifdef block where it
  is used. Remove now-unnecessary casts and arguments.
sql/set_var.cc:
  Replace bogus helpers with simple and classic bit operations.
sql/slave.cc:
  Cast to expected type and silence bogus warning.
sql/sql_class.h:
  Don't use enum values as bit flags, the supposed type safety is
  bogus as the combined bit flags are not a value in the enumeration.
sql/udf_example.c:
  Only declare variable when necessary.
sql/unireg.h:
  Replace use of bmove_align with memcpy.
storage/innobase/os/os0file.c:
  Silence bogus warning.
storage/myisam/mi_open.c:
  Remove bogus cast, DBUG_DUMP expects a pointer to unsigned
  char.
storage/myisam/mi_page.c:

  char.
strings/bcmp.c:

  Revert wrong patch from Oracle:
  - As QUICK_RANGE_SELECT uses it's own 'file' handler to the tables, one can't use 'table->key_read' as a flag to detect if index only read (keyread) is used or not
  - Don't set keyread if keyread is already enabled
  - Don't disable key read, if we didn't enable it ourselves
  - Simplify code (and ensure that we do proper cleanup of index only read)

  Added flags to detect if the range optimizer enabled index only read (key read) or not
sql/opt_sum.cc:
  Use our more optimized macros

  Use our more optimized keyread macros
  Added ASSERTS early
  Simplify code on eliminate_item_equal()
  Fixed that substitute_for_best_equal_field() doesn't core dump in case of out of memory conditions.
  Removed not needed test for 'field->maybe_null()'
  Replaced master_unit()->item with is_subquery_function() (More readable)
sql/sql_update.cc:
  Use our more optimized keyread macros
sql/table.cc:
  Use our more optimized keyread macros
sql/table.h:
  Use separate functions to enable/disable Index only reads
  - Safer, more readable, better logging and faster.

Bug#13174: SHA2 function
Patch contributed from Bill Karwin, paper unnumbered CLA in Seattle

Implement SHA2 functions.

Chad added code to make it work with YaSSL.  Also, he removed the 
(probable) bug of embedded server never using SSL-dependent 
functions.  (libmysqld/Makefile.am didn't read ANY autoconf defs.)

Function specification:
  SHA2( string cleartext, integer hash_length ) 
    -> string hash, or NULL
where hash_length is one of 224, 256, 384, or 512.  If either is 
NULL or a length is unsupported, then the result is NULL.  The 
resulting string is always the length of the hash_length parameter
or is NULL.

Include the canonical hash examples from the NIST in the test
results.

2acfdc5092 Bug #8433: Overflow must be an error 
All numeric operators and functions on integer, floating point 
and DECIMAL values now throw an 'out of range' error rather 
than returning an incorrect value or NULL,  when the result is 
out of supported range for the corresponding data type. 
 
Some test cases in the test suite had to be updated 
accordingly either because the test case itself relied on a 
value returned in case of a numeric overflow, or because a 
numeric overflow was the root cause of the corresponding bugs. 
The latter tests are no longer relevant, since the expressions 
used to trigger the corresponding bugs are not valid anymore. 
However, such test cases have been adjusted and kept "for the 
record".

c7fad393fd Bug #49829 Many "hides virtual function" warnings with 
SunStudio
      
SunStudio compilers of late warn about methods that might hide
methods in base classes due to the use of overloading combined
with overriding. SunStudio also warns about variables defined
in local socpe or method arguments that have the same name as
a member attribute of the class.
      
This patch renames methods that might hide base class methods,
to make it easier both for humans and compilers to see what is
actually called. It also renames variables in local scope.

4dc7be62a9 BUG#49222: Mark RAND() as unsafe 
Problem: When RAND() is binlogged in statement mode, the seed is
binlogged too, so the replication slave generates the same
sequence of random numbers. This makes replication work in many
cases, but not in all cases: the order of rows is not guaranteed
for, e.g., UPDATE or INSERT...SELECT statements, so the row data
will be different if master and slave retrieve the rows in
different orders.
Fix: Mark RAND() as unsafe. It will generate a warning if
binlog_format=STATEMENT and switch to row-logging if
binlog_format=ROW.

2f78abd21b BUG#47995: Mark system functions as unsafe 
Problem: Some system functions that could return different values on
master and slave were not marked unsafe. In particular:
 GET_LOCK
 IS_FREE_LOCK
 IS_USED_LOCK
 MASTER_POS_WAIT
 RELEASE_LOCK
 SLEEP
 SYSDATE
 VERSION
Fix: Mark these functions unsafe.


mysql-test/extra/rpl_tests/rpl_stm_000001.test:
  - The test does not work in mixed mode any more, since it tries to
    simulate an error in the sql thread in a query that uses get_lock.
    Since get_lock now causes the query to be logged in row format,
    the error didn't happen. Hence, we now force statement mode.
  - Warnings must be disabled when the unsafe query is issued.
  - Replaced some save_master_pos+connection slave+sync_with_master
    by sync_slave_with_master.

1ba25ae47c Bug #43414 Parenthesis (and other) warnings compiling MySQL 
with gcc 4.3.2
      
This patch fixes a number of GCC warnings about variables used
before initialized. A new macro UNINIT_VAR() is introduced for
use in the variable declaration, and LINT_INIT() usage will be
gradually deprecated. (A workaround is used for g++, pending a
patch for a g++ bug.)
      
GCC warnings for unused results (attribute warn_unused_result)
for a number of system calls (present at least in later
Ubuntus, where the usual void cast trick doesn't work) are
also fixed.


client/mysqlmanager-pwgen.c:
  A fix for warn_unused_result, adding fallback to use of
  srand()/rand() if /dev/random cannot be used. Also actually
  adds calls to rand() in the second branch so that it actually
  creates a random password.

f404c96e82 BUG#39934: Slave stops for engine that only support row-based logging 
This is a post-push fix addressing review requests and
problems with extra warnings.

Problem 1: The sub-statement where an unsafe warning was detected was
printed as part of the warning. This was ok for statements that
were unsafe due to, e.g., calls to UUID(), but did not make
sense for statements that were unsafe because there was more than
one autoincrement column (unsafeness in this case comes from the
combination of several sub-statements).
Fix 1: Instead of printing the sub-statement, print an explanation
of why the statement is unsafe.

Problem 2:
When a recursive construct (i.e., stored proceure, stored
function, trigger, view, prepared statement) contained several
sub-statements, and at least one of them was unsafe, there would be
one unsafeness warning per sub-statement - even for safe
sub-statements.
Fix 2:
Ensure that each type of warning is printed at most once, by
remembering throughout the execution of the statement which types
of warnings have been printed.


mysql-test/extra/rpl_tests/create_recursive_construct.inc:
  - Clarified comment per review request.
  - Added checks for the number of warnings in each invocation.
mysql-test/extra/rpl_tests/rpl_insert_delayed.test:
  Per review request, replaced @@session.binlog_format by
  @@global.binlog_format, since INSERT DELAYED reads the global
  variable. (In this test case, the two variables have the same
  value, so the change is cosmetic.)
mysql-test/r/sp_trans.result:
  updated result file
mysql-test/suite/binlog/r/binlog_statement_insert_delayed.result:
  updated result file
mysql-test/suite/binlog/r/binlog_stm_ps.result:
  updated result file
mysql-test/suite/binlog/r/binlog_stm_unsafe_warning.result:
  updated result file
mysql-test/suite/binlog/r/binlog_unsafe.result:
  Updated result file. Note that duplicate warnings are now gone.
mysql-test/suite/binlog/t/binlog_unsafe.test:
  - Added tests for: (1) a statement that is unsafe in many ways;
    (2) a statement that is unsafe in the same way several times.
  - Use -- style to invoke mysqltest commands.
mysql-test/suite/rpl/r/rpl_stm_found_rows.result:
  updated result file
mysql-test/suite/rpl/r/rpl_stm_loadfile.result:
  updated result file
mysql-test/suite/rpl/t/rpl_mix_found_rows.test:
  Per review request, added comment explaining what the test case
  does (copied from rpl_stm_found_rows.test)
mysql-test/suite/rpl/t/rpl_stm_found_rows.test:
  Clarified grammar in comment.
mysql-test/suite/rpl_ndb/r/rpl_ndb_binlog_format_errors.result:
  Updated result file.
sql/item_create.cc:
  Made set_stmt_unsafe take one parameter, describing the
  type of unsafeness.
sql/sp_head.cc:
  Added unsafe_flags field and made it hold all the unsafe flags.
sql/sp_head.h:
  - Removed the BINLOG_ROW_BASED_IF_MIXED flag from m_flags.
    Instead, we use the new unsafe_flags field to hold the
    unsafeness state of the sp.
  - Made propagate_attributes() copy all unsafe flags.
sql/sql_base.cc:
  - Made LEX::set_stmt_unsafe() take an extra argument.
  - Made binlog_unsafe_warning_flags store the type of unsafeness.
  - Per review requests, clarified comments
  - Added DBUG printouts
sql/sql_class.cc:
  - Made warnings be generated in issue_warnings() and call that from
    binlog_query(). Wrote issue_warnings(), which prints zero or more
    warnings, avoiding to print warnings more than once per statement.
  - Per review request, added @todo so that we remember to assert
    correct behavior in binlog_query.
sql/sql_class.h:
  - Removed BINLOG_WARNING_PRINTED 
  - Use [set|clear]_current_stmt_binlog_row_based() instead of
    modifying the flag directly.
  - added issue_unsafe_warnings() (only called from binlog_unsafe)
  - Per review request, improved some documentation.
sql/sql_insert.cc:
  Added extra argument to LEX::set_stmt_unsafe()
sql/sql_lex.h:
  - Added enum_binlog_stmt_unsafe, listing all types of unsafe
    statements.
  - Per review requests, improved many comments for member
    functions.
  - Added [get|set]_stmt_unsafe_flags(), which return/set all the
    unsafe flags for a statement.
sql/sql_parse.cc:
  - Renamed binlog_warning_flags to binlog_unsafe_warning_flags.
  - Per review requests, improved comment.
sql/sql_view.cc:
  Made views propagate all the new unsafe flags.
sql/sql_yacc.yy:
  Added parameter to set_stmt_unsafe().
storage/innobase/handler/ha_innodb.cc:
  Per review requests, replaced DBUG_EXECUTE_IF() by DBUG_EVALUATE_IF().

41783de549 BUG#39934: Slave stops for engine that only support row-based logging 
General overview:
The logic for switching to row format when binlog_format=MIXED had
numerous flaws. The underlying problem was the lack of a consistent
architecture.
General purpose of this changeset:
This changeset introduces an architecture for switching to row format
when binlog_format=MIXED. It enforces the architecture where it has
to. It leaves some bugs to be fixed later. It adds extensive tests to
verify that unsafe statements work as expected and that appropriate
errors are produced by problems with the selection of binlog format.
It was not practical to split this into smaller pieces of work.

Problem 1:
To determine the logging mode, the code has to take several parameters
into account (namely: (1) the value of binlog_format; (2) the
capabilities of the engines; (3) the type of the current statement:
normal, unsafe, or row injection). These parameters may conflict in
several ways, namely:
 - binlog_format=STATEMENT for a row injection
 - binlog_format=STATEMENT for an unsafe statement
 - binlog_format=STATEMENT for an engine only supporting row logging
 - binlog_format=ROW for an engine only supporting statement logging
 - statement is unsafe and engine does not support row logging
 - row injection in a table that does not support statement logging
 - statement modifies one table that does not support row logging and
   one that does not support statement logging
Several of these conflicts were not detected, or were detected with
an inappropriate error message. The problem of BUG#39934 was that no
appropriate error message was written for the case when an engine
only supporting row logging executed a row injection with
binlog_format=ROW. However, all above cases must be handled.
Fix 1:
Introduce new error codes (sql/share/errmsg.txt). Ensure that all
conditions are detected and handled in decide_logging_format()

Problem 2:
The binlog format shall be determined once per statement, in
decide_logging_format(). It shall not be changed before or after that.
Before decide_logging_format() is called, all information necessary to
determine the logging format must be available. This principle ensures
that all unsafe statements are handled in a consistent way.
However, this principle is not followed:
thd->set_current_stmt_binlog_row_based_if_mixed() is called in several
places, including from code executing UPDATE..LIMIT,
INSERT..SELECT..LIMIT, DELETE..LIMIT, INSERT DELAYED, and
SET @@binlog_format. After Problem 1 was fixed, that caused
inconsistencies where these unsafe statements would not print the
appropriate warnings or errors for some of the conflicts.
Fix 2:
Remove calls to THD::set_current_stmt_binlog_row_based_if_mixed() from
code executed after decide_logging_format(). Compensate by calling the
set_current_stmt_unsafe() at parse time. This way, all unsafe statements
are detected by decide_logging_format().

Problem 3:
INSERT DELAYED is not unsafe: it is logged in statement format even if
binlog_format=MIXED, and no warning is printed even if
binlog_format=STATEMENT. This is BUG#45825.
Fix 3:
Made INSERT DELAYED set itself to unsafe at parse time. This allows
decide_logging_format() to detect that a warning should be printed or
the binlog_format changed.

Problem 4:
LIMIT clause were not marked as unsafe when executed inside stored
functions/triggers/views/prepared statements. This is
BUG#45785.
Fix 4:
Make statements containing the LIMIT clause marked as unsafe at
parse time, instead of at execution time. This allows propagating
unsafe-ness to the view.


mysql-test/extra/rpl_tests/create_recursive_construct.inc:
  Added auxiliary file used by binlog_unsafe.test to create and
  execute recursive constructs
  (functions/procedures/triggers/views/prepared statements).
mysql-test/extra/rpl_tests/rpl_foreign_key.test:
  removed unnecessary set @@session.binlog_format
mysql-test/extra/rpl_tests/rpl_insert_delayed.test:
  Filter out table id from table map events in binlog listing.
  Got rid of $binlog_format_statement.
mysql-test/extra/rpl_tests/rpl_ndb_apply_status.test:
  disable warnings around call to unsafe procedure
mysql-test/include/rpl_udf.inc:
  Disabled warnings for code that generates warnings
  for some binlog formats. That would otherwise cause
  inconsistencies in the result file.
mysql-test/r/mysqldump.result:
  Views are now unsafe if they contain a LIMIT clause.
  That fixed BUG#45831. Due to BUG#45832, a warning is
  printed for the CREATE VIEW statement.
mysql-test/r/sp_trans.result:
  Unsafe statements in stored procedures did not give a warning if
  binlog_format=statement. This is BUG#45824. Now they do, so this
  result file gets a new warning.
mysql-test/suite/binlog/r/binlog_multi_engine.result:
  Error message changed.
mysql-test/suite/binlog/r/binlog_statement_insert_delayed.result:
  INSERT DELAYED didn't generate a warning when binlog_format=STATEMENT.
  That was BUG#45825. Now there is a warning, so result file needs to be
  updated.
mysql-test/suite/binlog/r/binlog_stm_ps.result:
  Changed error message.
mysql-test/suite/binlog/r/binlog_unsafe.result:
  updated result file:
   - error message changed
   - added test for most combinations of unsafe constructs invoked
     from recursive constructs
   - INSERT DELAYED now gives a warning (because BUG#45826 is fixed)
   - INSERT..SELECT..LIMIT now gives a warning from inside recursive
     constructs (because BUG#45785 was fixed)
   - When a recursive construct (e.g., stored proc or function)
     contains more than one statement, at least one of which is
     unsafe, then all statements in the recursive construct give
     warnings. This is a new bug introduced by this changeset.
     It will be addressed in a post-push fix.
mysql-test/suite/binlog/t/binlog_innodb.test:
  Changed error code for innodb updates with READ COMMITTED or 
  READ UNCOMMITTED transaction isolation level and
  binlog_format=statement.
mysql-test/suite/binlog/t/binlog_multi_engine.test:
  The error code has changed for statements where more than one
  engine is involved and one of them is self-logging.
mysql-test/suite/binlog/t/binlog_unsafe-master.opt:
  Since binlog_unsafe now tests unsafe-ness of UDF's, we need an extra
  flag in the .opt file.
mysql-test/suite/binlog/t/binlog_unsafe.test:
   - Clarified comment.
   - Rewrote first part of test. Now it tests not only unsafe variables
     and functions, but also unsafe-ness due to INSERT..SELECT..LIMIT,
     INSERT DELAYED, insert into two autoinc columns, use of UDF's, and
     access to log tables in the mysql database.
     Also, in addition to functions, procedures, triggers, and prepared
     statements, it now also tests views; and it constructs recursive
     calls in two levels by combining these recursive constructs.
     Part of the logic is in extra/rpl_tests/create_recursive_construct.inc.
   - added tests for all special system variables that should not be unsafe.
   - added specific tests for BUG#45785 and BUG#45825
mysql-test/suite/rpl/r/rpl_events.result:
  updated result file
mysql-test/suite/rpl/r/rpl_extraColmaster_innodb.result:
  updated result file
mysql-test/suite/rpl/r/rpl_extraColmaster_myisam.result:
  updated result file

  Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
  rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file equals
  the second half of the old rpl_found_rows.result, with the following
  modifications:
   - minor formatting changes
   - additional initialization
mysql-test/suite/rpl/r/rpl_mix_insert_delayed.result:
  Moved out code operating in mixed mode from rpl_stm_insert_delayed
  (into rpl_mix_insert_delayed) and got rid of explicit setting of
  binlog format.
mysql-test/suite/rpl/r/rpl_rbr_to_sbr.result:
  updated result file
mysql-test/suite/rpl/r/rpl_row_idempotency.result:
  Moved the second half of rpl_idempotency.test, which only
  executed in row mode, to rpl_row_idempotency.test. This is
  the new result file.

  Got rid of unnecessary explicit setting of binlog format.
mysql-test/suite/rpl/r/rpl_stm_found_rows.result:
  Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
  rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in
  this file:
   - minor formatting changes
   - warning is now issued for unsafe statements inside procedures
     (since BUG#45824 is fixed)
   - second half of file is moved to rpl_mix_found_rows.result
mysql-test/suite/rpl/r/rpl_stm_insert_delayed.result:
  Moved out code operating in mixed mode from rpl_stm_insert_delayed
  (into rpl_mix_insert_delayed) and got rid of explicit setting of
  binlog format.
mysql-test/suite/rpl/r/rpl_stm_loadfile.result:
  error message changed
mysql-test/suite/rpl/r/rpl_temporary_errors.result:
  updated result file
mysql-test/suite/rpl/r/rpl_udf.result:
  Remove explicit set of binlog format (and triplicate test execution)
  and rely on test system executing the test in all binlog formats.
mysql-test/suite/rpl/t/rpl_bug31076.test:
  Test is only valid in mixed or row mode since it generates row events.
mysql-test/suite/rpl/t/rpl_events.test:
  Removed explicit set of binlog_format and removed duplicate testing.
  Instead, we rely on the test system to try all binlog formats.
mysql-test/suite/rpl/t/rpl_extraColmaster_innodb.test:
  Removed triplicate testing and instead relying on test system.
  Test is only relevant for row format since statement-based replication
  cannot handle extra columns on master.
mysql-test/suite/rpl/t/rpl_extraColmaster_myisam.test:
  Removed triplicate testing and instead relying on test system.
  Test is only relevant for row format since statement-based replication
  cannot handle extra columns on master.
mysql-test/suite/rpl/t/rpl_idempotency-slave.opt:
  Removed .opt file to avoid server restarts.
mysql-test/suite/rpl/t/rpl_idempotency.test:
  - Moved out row-only tests to a new test file, rpl_row_idempotency.test.
    rpl_idempotency now only contains tests that execute in all
    binlog_formats.
  - While I was here, also removed .opt file to avoid server restarts.
    The slave_exec_mode is now set inside the test instead.
mysql-test/suite/rpl/t/rpl_mix_found_rows.test:
  Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
  rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file
  contains the second half of the original rpl_found_rows.test with the
  follwing changes:
   - initialization
   - removed SET_BINLOG_FORMAT and added have_binlog_format_mixed.inc
   - minor formatting changes
mysql-test/suite/rpl/t/rpl_mix_insert_delayed.test:
  Moved out code operating in mixed mode from rpl_stm_insert_delayed
  (into rpl_mix_insert_delayed) and got rid of explicit setting of
  binlog format.
mysql-test/suite/rpl/t/rpl_rbr_to_sbr.test:
  Test cannot execute in statement mode, since we no longer
  switch to row format when binlog_format=statement.
  Enforced mixed mode throughout the test.
mysql-test/suite/rpl/t/rpl_row_idempotency.test:
  Moved the second half of rpl_idempotency.test, which only
  executed in row mode, to this new file. We now rely on the
  test system to set binlog format.
mysql-test/suite/rpl/t/rpl_row_insert_delayed.test:
   - Got rid of unnecessary explicit setting of binlog format.
   - extra/rpl_tests/rpl_insert_delayed.test does not need the
     $binlog_format_statement variable any more, so that was
     removed.
mysql-test/suite/rpl/t/rpl_slave_skip.test:
  The test switches binlog_format internally and master generates both
  row and statement events. Hence, the slave must be able to log in both
  statement and row format. Hence test was changed to only execute in
  mixed mode.
mysql-test/suite/rpl/t/rpl_stm_found_rows.test:
  Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
  rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in
  this file:
   - minor formatting changes
   - added have_binlog_format_statement and removed SET BINLOG_FORMAT.
   - second half of file is moved to rpl_mix_found_rows.test
   - added cleanup code
mysql-test/suite/rpl/t/rpl_stm_insert_delayed.test:
  Moved out code operating in mixed mode from rpl_stm_insert_delayed
  (into rpl_mix_insert_delayed) and got rid of explicit setting of
  binlog format.
mysql-test/suite/rpl/t/rpl_switch_stm_row_mixed.test:
  The test switches binlog_format internally and master generates both
  row and statement events. Hence, the slave must be able to log in both
  statement and row format. Hence test was changed to only execute in
  mixed mode on slave.
mysql-test/suite/rpl/t/rpl_temporary_errors.test:
  Removed explicit set of binlog format. Instead, the test now only
  executes in row mode.
mysql-test/suite/rpl/t/rpl_udf.test:
  Remove explicit set of binlog format (and triplicate test execution)
  and rely on test system executing the test in all binlog formats.
mysql-test/suite/rpl_ndb/combinations:
  Added combinations file for rpl_ndb.
mysql-test/suite/rpl_ndb/r/rpl_ndb_binlog_format_errors.result:
  new result file
mysql-test/suite/rpl_ndb/r/rpl_ndb_circular_simplex.result:
  updated result file
mysql-test/suite/rpl_ndb/t/rpl_ndb_2innodb.test:
  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.
mysql-test/suite/rpl_ndb/t/rpl_ndb_2myisam.test:
  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.

  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.

mysql-test/t/partition_innodb_stmt.test:
  Changed error code for innodb updates with READ COMMITTED or 
  READ UNCOMMITTED transaction isolation level and
  binlog_format=statement.
sql/event_db_repository.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/events.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/ha_ndbcluster_binlog.cc:
  reset_current_stmt_binlog_row_based() is not a no-op for the ndb_binlog
  thread any more. Instead, the ndb_binlog thread now forces row mode both
  initially and just after calling mysql_parse.  (mysql_parse() is the only
  place where reset_current_stmt_binlog_row_based() may be called from
  the ndb_binlog thread, so these are the only two places that need to
  change.)
sql/ha_partition.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/handler.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/item_create.cc:
  Added DBUG_ENTER to some functions, to be able to trace when
  set_stmt_unsafe is called.
sql/log.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/log_event.cc:
   - Moved logic for changing to row format out of do_apply_event (and into
     decide_logging_format).
   - Added @todo comment for post-push cleanup.
sql/log_event_old.cc:
  Move logic for changing to row format out of do_apply_event (and into
  decide_logging_format).
sql/mysql_priv.h:
  Make decide_logging_format() a member of the THD class, for two reasons:
   - It is natural from an object-oriented perspective.
   - decide_logging_format() needs to access private members of THD
     (specifically, the new binlog_warning_flags field).
sql/rpl_injector.cc:
  Removed call to set_current_stmt_binlog_row_based().
  From now on, only decide_logging_fromat is allowed to modify
  current_stmt_binlog_row_based. This call is from the ndb_binlog
  thread, mostly executing code in ha_ndbcluster_binlog.cc.
  This call can be safely removed, because:
   - current_stmt_binlog_row_based is initialized for the ndb_binlog
     thread's THD object when the THD object is created. So we're
     not going to read uninitialized memory.
   - The behavior of ndb_binlog thread does not use the state of the
     current_stmt_binlog_row_based. It is conceivable that the
     ndb_binlog thread would rely on the current_stmt_binlog_format
     in two situations:
      (1) when it calls mysql_parse;
      (2) when it calls THD::binlog_query.
     In case (1), it always clears THD::options&OPTION_BIN_LOG (because
     run_query() in ha_ndbcluster_binlog.cc is only called with
     disable_binlogging = TRUE).
     In case (2), it always uses qtype=STMT_QUERY_TYPE.
sql/set_var.cc:
  Added @todo comment for post-push cleanup.
sql/share/errmsg.txt:
  Added new error messages and clarified ER_BINLOG_UNSAFE_STATEMENT.
sql/sp.cc:
  Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called.
  Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE.
sql/sp_head.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sp_head.h:
  Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called.
sql/sql_acl.cc:
  Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE.
sql/sql_base.cc:
   - Made decide_logging_format take care of all logic for deciding the
     logging format, and for determining the related warnings and errors.
     See comment above decide_logging_format for details.
   - Made decide_logging_format a member function of THD, since it needs
     to access private members of THD and since its purpose is to update
     the state of a THD object.
   - Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called.
sql/sql_class.cc:
  - Moved logic for determining unsafe warnings away from THD::binlog_query
    (and into decide_logging_format()). Now, it works like this:
    1. decide_logging_format detects that the current statement shall
       produce a warning, if it ever makes it to the binlog
    2. decide_logging_format sets a flag of THD::binlog_warning_flags.
    3. THD::binlog_query reads the flag. If the flag is set, it generates
       a warning.
  - Use member function to read current_stmt_binlog_row_based.
sql/sql_class.h:
  - Added THD::binlog_warning_flags (see sql_class.cc for explanation).
  - Made decide_logging_format() and reset_for_next_command() member
    functions of THD (instead of standalone functions). This was needed
    for two reasons: (1) the functions need to access the private member
    THD::binlog_warning_flags; (2) the purpose of these functions is to
    update the staet of a THD object, so from an object-oriented point
    of view they should be member functions.
  - Encapsulated current_stmt_binlog_row_based, so it is now private and
    can only be accessed from a member function. Also changed the
    data type to an enumeration instead of a bool.
  - Removed MYSQL_QUERY_TYPE, because it was equivalent to
    STMT_QUERY_TYPE anyways.
  - When reset_current_stmt_binlog_row_based was called from the
    ndb_binlog thread, it would behave as a no-op. This special
    case has been removed, and the behavior of
    reset_current_stmt_binlog_row_based does not depend on which thread
    calls it any more. The special case did not serve any purpose,
    since the ndb binlog thread did not take the
    current_stmt_binlog_row_based flag into account anyways.
sql/sql_delete.cc:
  - Moved logic for setting row format for DELETE..LIMIT away from
    mysql_prepare_delete.
    (Instead, we mark the statement as unsafe at parse time (sql_yacc.yy)
    and rely on decide_logging_format() (sql_class.cc) to set row format.)
    This is part of the fix for BUG#45831.
  - Use member function to read current_stmt_binlog_row_based.
sql/sql_insert.cc:
   - Removed unnecessary calls to thd->lex->set_stmt_unsafe() and
     thd->set_current_stmt_binlog_row_based_if_mixed() from
     handle_delayed_insert(). The calls are unnecessary because they
     have already been made; they were made in the constructor of
     the `di' object.
   - Since decide_logging_format() is now a member function of THD, code
     that calls decide_logging_format() had to be updated.
   - Added DBUG_ENTER call, to be able to trace when set_stmt_unsafe is
     called.
   - Moved call to set_stmt_unsafe() for INSERT..SELECT..LIMIT away from
     mysql_insert_select_prepare() (and into decide_logging_format).
     This is part of the fix for BUG#45831.
   - Use member function to read current_stmt_binlog_row_based.
sql/sql_lex.h:
   - Added the flag BINLOG_STMT_FLAG_ROW_INJECTION to enum_binlog_stmt_flag.
     This was necessary so that a statement can identify itself as a row
     injection.
   - Added appropriate setter and getter functions for the new flag.
   - Added or clarified some comments.
   - Added DBUG_ENTER()
sql/sql_load.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sql_parse.cc:
   - Made mysql_reset_thd_for_next_command() clear thd->binlog_warning_flags.
   - Since thd->binlog_warning_flags is private, it must be set in a
     member function of THD. Hence, moved the body of
     mysql_reset_thd_for_next_command() to the new member function
     THD::reset_thd_for_next_command(), and made
     mysql_reset_thd_for_next_command() call
     THD::reset_thd_for_next_command().
   - Removed confusing comment.
   - Use member function to read current_stmt_binlog_row_based.
sql/sql_repl.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sql_table.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sql_udf.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sql_update.cc:
  Moved logic for setting row format for UPDATE..LIMIT away from
  mysql_prepare_update.
  (Instead, we mark the statement as unsafe at parse time (sql_yacc.yy)
  and rely on decide_logging_format() (sql_class.cc) to set row format.)
  This is part of the fix for BUG#45831.
sql/sql_yacc.yy:
  Made INSERT DELAYED, INSERT..SELECT..LIMIT, UPDATE..LIMIT, and
  DELETE..LIMIT mark themselves as unsafe at parse time (instead
  of at execution time).
  This is part of the fixes BUG#45831 and BUG#45825.
storage/example/ha_example.cc:
  Made exampledb accept inserts. This was needed by the new test case
  rpl_ndb_binlog_format_errors, because it needs an engine that
  is statement-only (and accepts inserts).
storage/example/ha_example.h:
  Made exampledb a statement-only engine instead of a row-only engine.
  No existing test relied exampledb's row-only capabilities. The new
  test case rpl_ndb_binlog_format_errors needs an engine that is
  statement-only.
storage/innobase/handler/ha_innodb.cc:
  - Changed error error code and message given by innodb when 
    binlog_format=STATEMENT and transaction isolation level is
    READ COMMITTED or READ UNCOMMITTED.
  - While I was here, also simplified the condition for
    checking when to give the error.
