Implement wrapper functions in the plugin. The plugin will get the
function entries from mysqld.exe during the init, and invoke the
corresponding functions (in mysqld.exe). The list of functions are:
_db_pargs_
_db_doprnt_
_db_enter_
_db_return_
_db_dump_

when INNODB_DYNAMIC_PLUGIN is specified.
The changes are:
CMakeLists.txt: add project ha_innodb for dynamic plugin on Windows.
ha_innodb depends on project mysqld.
ha_innodb.def: a new file with standard exports for a dynamic plugin.
Two new files will be added:
* sql/mysqld.def: .def file for 32-bit compiler
* sql/mysqld_x64.def: .def file for x64 compiler
It is also required to apply a patch to the MySQL source tree. The
patch is described in win-plugin/README:
win-plugin/win-plugin.diff - a patch to be applied to MySQL source
tree. When applied, the following files will be modified:
* CMakeLists.txt: add INNODB_DYNAMIC_PLUGIN and _USE_32BIT_TIME_T
* sql/CMakeLists.txt: add mysqld.def or mysqld_x64.def for mysqld
* win/configure.js: add INNODB_DYNAMIC_PLUGIN
* win/build-vs71.bat: provide an option to specify CMAKE_BUILD_TYPE
* win/build-vs8.bat: provide an option to specify CMAKE_BUILD_TYPE
* win/build-vs8_x64.bat: provide an option to specify CMAKE_BUILD_TYPE
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
system variables.
handler/handler0alter.cc: add a header file
handler/i_s.cc: add a header file

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.

have to check the available space on the uncompressed page.
Otherwise, the clustered index record can be almost 16 kilobytes in

Fix Mantis issue#61:
In row_undo_ins_parse_undo_rec(): if we find that a table has no indexes
(dict_table_get_first_index() returns NULL) do not try to call
trx_undo_rec_get_row_ref() with a NULL pointer because that would lead to
a crash. Instead, print a warning and set node->table to NULL just like
it is done if the .ibd file is missing.

In ROW_FORMAT=DYNAMIC and ROW_FORMAT=COMPRESSED, column prefix indexes
require that prefixes of externally stored columns be written to the
undo log. This may make the undo log record bigger than the record on
the B-tree page. The maximum size of an undo log record is the page
size. That must be checked for, in dict_index_add_to_cache().
dict_index_add_to_cache(): Skip the undo log size check for REDUNDANT
and COMPACT tables. These tables store prefixes of externally stored
columns locally within the clustered index record. There are no special
considerations for the undo log record size.
innodb-index.test: Ensure that the check exists for ROW_FORMAT=DYNAMIC,
but not for ROW_FORMAT=COMPACT.
This fixes issue #99. rb://28 approved by Sunny.
column of a compressed table, the BTR_EXTERN_LEN field in the BLOB pointer
will be written as 0. Tolerate this in the functions that deal with
externally stored columns. This fixes Issue #80 and was posted at rb://26.
Note that the clustered index record is always deleted or purged last,
after any secondary index records referring to it have been deleted.
btr_free_externally_stored_field(): On an uncompressed table, zero out
the BTR_EXTERN_LEN, so that half-deleted BLOBs can be detected after
crash recovery.
btr_copy_externally_stored_field_prefix(): Return 0 if the BLOB has been
half-deleted.
row_upd_ext_fetch(): Assert that the externally stored column exists.
row_ext_cache_fill(): Allow btr_copy_externally_stored_field_prefix()
to return 0.
row_sel_sec_rec_is_for_blob(): Return FALSE if the BLOB has been half-deleted.
This is correct, because the clustered index record would have been deleted
or purged last, after any secondary index records referring to it had been
deleted.

ha_innobase::add_index(): Lock the data dictionary before invoking
row_merge_rename_indexes() or row_merge_drop_indexes(), because neither
function will commit the transaction.

unlocking the data dictionary.
row_merge_drop_index(), row_merge_drop_indexes(), row_merge_rename_tables(),
row_merge_rename_indexes(): Note and assert that the data dictionary must
have been exclusively locked by the caller, because the transaction will
not be committed.
row_drop_database_for_mysql(): Commit the transaction immediately after
dropping each table. When MySQL is holding open handles to some tables,
it can otherwise occur than the data dictionary is unlocked while the
transaction has not been committed. This bug was introduced in r2739,
which changed the semantics of row_drop_table_for_mysql().
row_drop_database_for_mysql(): Postpone mem_free(table_name), so that
an error printout will not dereference freed memory.
