by binlogging some SET ONE_SHOT CHARACTER_SETetc,
which will be enough until we have it more compact and more complete in 5.0. With the present patch,
replication will work ok between 4.1.3 master and slaves, as long as:
- master and slave have the same GLOBAL.COLLATION_SERVER
- COLLATION_DATABASE and CHARACTER_SET_DATABASE are not used
- application does not use the fact that table is created with charset of the USEd db (BUG#2326).
all of which are not too hard to fulfill.
ONE_SHOT is reserved for internal use of mysqlbinlog|mysql and works only for charsets,
so we give error if used for non-charset vars.
Fix for BUG#3875 "mysqlbinlog produces wrong ouput if query uses
variables containing quotes" and BUG#3943 "Queries with non-ASCII literals are not replicated
properly after SET NAMES".
Detecting that master and slave have different global charsets or server ids.

escape the content of the var. Backquote its name.
Will ask Bar to check that using my_charset_bin for escaping is ok.
sql/set_var.cc:
understand SET CHARACTER_SET_CLIENT=10 (don't require a string, accept a number).
Refuse changing of GLOBAL CHARACTER_SET_SERVER/COLLATION_SERVER if binlog or slave,
as it will make the master or slave make wrong assumptions.

sql/slave.cc:

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).

sql/handler.cc:
Do not use the transaction binlog cache if binlog is not open
sql/sql_class.cc:
We do not init the transaction binlog cache if binlog is not open.
This saves 32 KB memory per thread, if --log-bin is not used.
sql/sql_class.h:
warning comment
init the binlog_cache (THD::transaction.trans_log).
I have checked all places where trans_log is used, because as now
it may not be inited in some cases, we have to be cautious
(will forward this commit mail to Heikki).

reviewed in Saint-Petersbourg (including post-review fixes).
include/my_sys.h:
Added clear_alloc_root (reset alloc root without freeing its memory)
sql/item.h:
- rename setup_param -> set_parap (function assigns parameter value to item)
sql/mysql_priv.h:
- all return values are void, because return value is never checked in
dispatch_command
- removed unused declaration of setup_param_functions
sql/protocol.h:
- unused declarations of setup_params_data* removed
sql/sql_class.cc:
Cleanup:
- bzero(mem_root) replaced with clear_alloc_root
- query_id and command members moved back to THD from Statement
Assignment of mem_root, free_list, query_id and command optimized
away from set_statement().
sql/sql_class.h:
- query_id and command moved back to THD from Statement
sql/sql_lex.h:
- better type for param_list
- param_count is the same thing as param_list.elements
sql/sql_parse.cc:
- comments for dispatch_command
sql/sql_prepare.cc:
Cleanup:
- added comments to many functions and removed trailing spaces in many
lines, some stale comments removed.
- it's faster to iterate using pointers, than classes
- Renames: error_in_prepare renamed to get_longdata_error (because it is set
when there is an error in mysql_send_longdata, rather than in
mysql_prepare), embedded versions of placeholder assignement functions
now have prefix emb_, setup_ functions renamed to set_, because they
perform assignment, not installation, setup_params_data now doesn't
call insert_params and was renamed to setup_set_param_functions,
- find_prepared_statement should not send error if called from no-reply
calls, like mysql_stmt_reset
- error reporting is checked up, to always report errors and not report
errors twice. send_prep_stmt can be done mostly in send_prepare_result,
rather than in test_* functions.
- now we don't need to reinit THD->mem_root/free_list in mysql_stmt_execute,
because it's not reset there.
tests/client_test.c:
- removed second call to test_subqueries
