rec_set_nth_field(): When the field already is SQL null,
do nothing when it is being changed to SQL null. (Bug #41571)
Normally, MySQL does not pass "do-nothing" updates to the storage engine.
When it does and a column of an InnoDB table that is in ROW_FORMAT=COMPACT
is being updated from NULL to NULL, the InnoDB buffer pool will be corrupted
without this fix.

buf_flush_batch(): Move the common statement mutex_exit(block_mutex)

redundant test (buf_pool->init_flush[flush_type] == FALSE) that was
apparently copied from buf_flush_write_complete().

buf_pool_mutex and block_mutex must now be held upon entering the

The config param innodb_thread_concurrency is dynamically set and is
read when a thread enters/exits innodb. If the value is changed between
the enter and exit time the behaviour becomes erratic.
The fix is not to use srv_thread_concurrency when exiting, instead use
the flag trx->declared_to_be_inside_innodb.

message:
A fix for Bug#22891 "session level max_allowed_packet can be
set but is ignored".
This patch makes @@session.max_allowed_packed and
@@session.net_buffer_length read-only as suggested in the bug
report. The user will have to use SET GLOBAL (and reconnect)
to alter the session values of these variables.
The error string ER_VARIABLE_IS_READONLY is introduced.
Tests are modified accordingly.

The first "row too large" check was implemented in MySQL 5.0.3

accurate check was implemented in innodb_strict_mode. We now
make the check unconditional.

branches/zip: implement the delayloading of externals for the plugin
on Windows, which includes:
* Load mysqld.map and insert all symbol/address pairs into hash for
quick access
* Resolves all external data variables. The delayloading mechanism
in MSVC does not support automatic imports of data variables.
A workaround is to explicitly handle the data import using the delay
loader during the initialization of the plugin.
* Resolves all external functions during run-time, by implementing
the delayed loading helper function delayLoadHelper2, which is
called by run-time as well as HrLoadAllImportsForDll.
The delay loader reuses the hash implementation in InnoDB. The normal
hash_create (in hash0hash.c) creates hash tables in buffer pool. But
the delay loader is invoked before the engine is initialized, and
buffer pools are not ready yet. Instead, the delay loader has its own
implementation of hash_create() and hash_table_free(), called
wdl_hash_create() and wdl_hash_table_free().
This patch should be used with other two patches in order to build
a dynamically linked plugin on Windows:
* patch for tmpfile functions (r2886)
* patch for "build" files (to be committed)
The list of file changed:
handler/handler0vars.h: new file, defines a list of external data
variables (no external functions).
handler/win_delay_loader.cc: new file, the implementation of the delay
loader for Windows plugin.
handler/ha_innodb.cc: add a header file, and changes for copying the

branches/5.1: dtype_get_sql_null_size(): return the correct storage
size of a SQL NULL column. (Bug #40369)
When MySQL Bug #20877 was fixed in r834, this function was
accidentally modified to return 0 or 1. Apparently, the only impact of
this bug is that fixed-length columns cannot be updated in-place from
or to SQL NULL, even in ROW_FORMAT=REDUNDANT. After this fix,
fixed-length columns in ROW_FORMAT=REDUNDANT will have a constant
storage size as they should, no matter if NULL or non-NULL. The bug
caused fixed-length NULL columns to occupy 1 byte.

Fix "Bug#40360 Binlog related errors with binlog off" in InnoDB code in order

The fix does check whether binary logging is enabled in MySQL by accessing the
opt_bin_log global variable that is defined in sql/mysqld.cc.
In case MySQL does develop another solution to this via Bug#40360 then we can
revert this patch (except the mysql-tests).

branches/zip: ha_innobase::create(): Remove the dependences on
DICT_TF_ZSSIZE_MAX, so that the code can be compiled with a different
uncompressed page size by redefining UNIV_PAGE_SIZE_SHIFT in univ.i.
Currently, the allowed values are 12, 13, or 14 (4k, 8k, 16k).
Make the default compressed page size half the uncompressed page size.
The previous default was 8 kilobytes, which is the same when compiling
with the default 16k uncompressed page size.

branches/zip: Clean up the file format stamping.
trx_sys_file_format_max_upgrade(): Rename from
trx_sys_file_format_max_update(). Improve the documentation. Add a
const qualifier to the parameter "name". Replace the parameter
"flags" with "format_id", because this function should deal with file
format identifiers, not with table flags.
trx_sys_file_format_max_write(), trx_sys_file_format_max_set(): Add a
const qualifier to the parameter "name".
ha_innodb.cc: Correct the spelling in some comments: "side effect".
Remove redundant prototypes for some static callback functions.
innodb_file_format_name_update(), innodb_file_format_check_update():
Correct the function signature. Use appropriate pointer type conversions.
MYSQL_SYSVAR_STR(file_format), MYSQL_SYSVAR_STR(file_format_check):
Remove the type conversions from the callback function pointers. When
the function signatures match, no type conversion is needed. The type
conversions would only prevent compilation warnings for any mismatch.

in r2276. Now the following symbols will be exported when InnoDB is built
as a dynamic plugin:
* the virtual method pointer table of class ha_innodb
* the three variables that MySQL will reference when linking at runtime:
_mysql_plugin_declarations_
_mysql_plugin_interface_version_
_mysql_sizeof_struct_st_plugin_
Furthermore, the following symbols are weak globals, to allow us to access
the built-in InnoDB in the mysqld executable, in case it contains a statically
linked InnoDB:
builtin_innobase_plugin
innodb_hton_ptr
symbols. Use it for all definitions of non-static variables and functions.
lexyy.c, make_flex.sh: Declare yylex as UNIV_INTERN, not static. It is
referenced from pars0grm.c.
Actually, according to
nm .libs/ha_innodb.so|grep -w '[ABCE-TVXYZ]'
the following symbols are still global:
* The vtable for class ha_innodb
* pars0grm.c: The function yyparse() and the variables yychar, yylval, yynerrs
The required changes to the Bison-generated file pars0grm.c will be addressed
in a separate commit, which will add a script similar to make_flex.sh.
The class ha_innodb is renamed from class ha_innobase by a #define. Thus,
there will be no clash with the builtin InnoDB. However, there will be some
overhead for invoking virtual methods of class ha_innodb. Ideas for making
the vtable hidden are welcome. -fvisibility=hidden is not available in GCC 3.
btr_cur_pessimistic_update(): Note why the externally stored columns

ha_innobase::final_drop_index(): Lock the user table within prebuilt->trx.
to the undo log, also store the original length of the column, so that the
changes will be correctly undone in transaction rollback or when fetching
previous versions of the row.
innodb-zip.test: New file, for tests of the compression.
upd_field_t: Add orig_len, the original length of new_val.
btr_push_update_extern_fields(): Restore the original prefix of the column.
Add the parameter heap where memory will be allocated if necessary.
trx_undo_rec_get_col_val(): Add the output parameter orig_len.
trx_undo_page_report_modify_ext(): New function: Write an externally
stored column to the undo log. This is only called from
trx_undo_page_report_modify(), and this is the only caller of
trx_undo_page_fetch_ext().
trx_undo_update_rec_get_update(): Read the original length of the column
prefix to upd_field->orig_len.
row_build(), row_upd_index_replace_new_col_vals_index_pos(), and
row_upd_index_replace_new_col_vals() are safe.
btr_cur_optimistic_update(), btr_cur_pessimistic_update(): Note that
the B-tree page of the clustered index record is latched in mtr.
trx_undo_prev_version_build(): Add const qualifiers to index_rec
and rec. Note that the page of index_rec is latched in index_mtr.
row_vers_impl_x_locked_off_kernel(), row_vers_old_has_index_entry():
Note that the stack of versions is locked by mtr and thus it is
safe to call row_build().
Change the format of TRX_IDs in INFORMATION_SCHEMA tables from DEC to
HEX.
The current TRX_IDs are hard to remember and track down: 426355, 428466,
428566, etc.
In HEX:
* there are less "digits", the strings are shorter;
* since there are 16 instead of 10 "digits", the chance of having
repeating ones are smaller.
The above look like 68173, 689B2, 68A16 in HEX.

enough prefixes of externally stored columns, so that purge will not have
to dereference any BLOB pointers, which may be invalid. This will not be
necessary for logging inserts, because inserts are no-ops in purge, and
the record will remain locked during transaction rollback.
TODO: in dict_build_table_def_step() or dict_build_index_def_step(),
prevent the creation of tables with too many columns for which a
prefix index is defined. This is because there is a size limit of undo
log records, and for each prefix-indexed column, the log must store
REC_MAX_INDEX_COL_LEN + BTR_EXTERN_FIELD_REF_SIZE bytes.
trx_undo_page_report_insert(): Assert that the index is clustered.
trx_undo_page_fetch_ext(): New function, for fetching the BLOB prefix
in trx_undo_page_report_modify().
trx_undo_page_report_modify(): Write long enough prefixes of the externally
stored columns to the undo log.
trx_undo_rec_get_partial_row(): Remove the parameter "ext". Assert that
the undo log contains long enough prefixes of the externally stored columns.
purge_node_t: Remove the field "ext".
* Change terminology:
wait lock -> requested lock
waited lock -> blocking lock
new: requesting transaction (the trx what owns the requested lock)
new: blocking transaction (the trx that owns the blocking lock)
* Add transaction ids to INFORMATION_SCHEMA.INNODB_LOCK_WAITS. This is
somewhat redundant because transaction ids can be found in INNODB_LOCKS
(which can be joined with INNODB_LOCK_WAITS) but would help users to
write shorter joins (one table less) in some cases where they want to
find which transaction is blocking which.

row_ext_create(): Add the parameter "tuple". Move the implementation
from row0ext.ic to row0ext.c.

Add the query in information_schema.innodb_trx.trx_query. Add it even
though it is available in information_schema.processlist.info to make
inconsistencies between those two tables obvious.
It is rather confusting to see a transaction shown in innodb_trx and
innodb_locks that holds a lock on one table and the corresponding query
in processlist executing INSERT on another table. We do not want users
to contact us asking to explain that. It is caused by the fact that the
data for innodb_* tables and processlist is fetched at different time.
