dtuple_validate(): Detect uninitialized data.
page_cur_insert_rec_low(), page_cur_insert_rec_zip(): Assert that the
record being inserted is valid before and after insertion.
INNODB_ZIP and INNODB_ZIP_RESET from ha_innodb.cc to i_s.cc.
plugin_author, END_OF_ST_FIELD_INFO, i_s_info: New common constants.
trx_i_s_common_deinit(): Renamed to i_s_common_deinit().
For some reason, GCC 4.2.1 ignores casts (for removing constness)
in calls to inline functions.
page_align(), ut_align_down(): Make the parameter const void*, but still
return a non-const pointer. This is ugly, but these functions cannot be
replaced with a const-preserving macro in a portable way, given that
the pointer argument is not always pointing to bytes.
buf_block_get_page_zip(): Implement as a const-preserving macro.
buf_frame_get_page_zip(), buf_block_align(): Add const qualifiers.
lock_rec_get_prev(): Silence GCC 4.2.1 warnings.
mlog_write_initial_log_record(), mlog_write_initial_log_record_fast(),
mtr_memo_contains(): Add const qualifier to the pointer.
page_header_get_ptr(): Rewrite as page_header_get_offs(), and
implement as a macro that calls this function.
buf_block_hash_get(): New function, similar to buf_page_hash_get().
buf_page_get_block(): Remove the const qualifiers. This is a low-level
function, and the operations on block->mutex are non-const.
buf_page_try_get_func(): Implement with lower-level predicates, somewhat
similar to buf_page_get_known_nowait().
lock_rec_print(): Remove the unused variable zip_size and the
call to fil_space_get_zip_size(). Adapt to buf_page_try_get() returning
a const pointer.
ha_innobase::update_thd(void): New function, to call the inline function
ha_innobase::update_thd(THD*).
check_trx_exists(): Make static. handler0alter.cc does not need to call
this function.
offsets_[] arrays, as suggested by Vasil.
rec_offs_set_n_alloc(): Declare as a public function. Assert that
n_alloc > REC_OFFS_HEADER_SIZE.
rec_offs_get_n_alloc(): Assert that n_alloc > REC_OFFS_HEADER_SIZE.
Move part of the code from lock_rec_print() in a separate function
buf_page_try_get() because the same functionality is needed in
INFORMATION SCHEMA code.

Fix a bug where the condition (prtype & DATA_ROW_ID) is unexpectedly
always false becasue DATA_ROW_ID is 0.
Use a switch instead of if-else in order to avoid repeating
(prtype & DATA_SYS_PRTYPE_MASK).

innobase_col_to_mysql(): New function, adapted from
row_sel_field_store_in_mysql_format().
innobase_rec_to_mysql(): Correct the function comment, which was still
saying "clustered index record", although we can convert any record.
Make use of innobase_col_to_mysql(). Always call field->reset(),
so that innobase_col_to_mysql() will not have to pad anything.
Since r1905, innobase_rec_to_mysql() does not require a clustered index record.
row_merge_dup_t: Remove old_table.
row_merge_dup_report(): Do not fetch the clustered index record. Simply
convert the tuple by innobase_rec_to_mysql().
row_merge_blocks(), row_merge(), row_merge_sort(): Add a TABLE* parameter
for reporting duplicate key values during file sort.
row_merge_read_clustered_index(): Replace UNIV_PAGE_SIZE with the more
appropriate sizeof(mrec_buf_t).
dtuple_create_for_mysql(), dtuple_free_for_mysql(): Remove.
ha_innobase::records_in_range(): Use mem_heap_create(), mem_heap_free(),
and dtuple_create() instead of the removed functions above. Since r1587,
InnoDB C++ functions can invoke inlined C functions.
innobase_rec_to_mysql(): New function, for converting an InnoDB clustered
index record to MySQL table->record[0]. TODO: convert integer fields.
Currently, integer fields are in big-endian byte order instead of
host byte order, and signed integer fields are offset by 0x80000000.
innobase_rec_reset(): New function, for resetting table->record[0].
row_merge_build_indexes(): Add the parameter TABLE* table (the MySQL table
handle) for reporting duplicate key values.
dtuple_from_fields(): New function, to convert an array of dfield_t* to
dtuple_t.
dtuple_get_n_ext(): New function, to compute the number of externally stored
fields.
row_merge_dup_t: Structure for counting and reporting duplicate records.
row_merge_dup_report(): Function for counting and reporting duplicate records.
row_merge_tuple_cmp(), row_merge_tuple_sort(): Replace the ulint* n_dup
parameter with row_merge_dup_t* dup.
row_merge_buf_sort(): Add the parameter row_merge_dup_t* dup, which is
NULL when sorting a non-unique index.
row_merge_buf_write(), row_merge_heap_create(), row_merge_read_rec(),
row_merge_cmp(), row_merge_read_clustered_index(), row_merge_blocks(),
row_merge(), row_merge_sort(): Add const qualifiers.
row_merge_read_clustered_index(): Use a common error handling branch err_exit.
Invoke row_merge_buf_sort() differently on unique indexes.
row_merge_blocks(): note TODO: We could invoke innobase_rec_to_mysql()
to report duplicate key values when creating a clustered index.
dict_find_index_by_max_id(): Rename this static function to its
only caller, dict_table_get_index_by_max_id().
dict_table_get_index_by_max_id(): Copy the function comment from
dict_find_index_by_max_id().
rec_get_converted_size_comp(), rec_convert_dtuple_to_rec_comp(),
rec_convert_dtuple_to_rec_new(), rec_convert_dtuple_to_rec(): Add a
const qualifier to dict_index_t*.
row_search_on_row_ref(): Add const qualifiers to the dict_table_t*
and dtuple_t* parameters. Note that pcur is an "out" parameter
and mtr is "in/out".
dtuple_create(): Simplify a pointer expression. Flag the fields uninitialized
after initializing them in the debug version.
dtuple_t: Only declare magic_n if UNIV_DEBUG is defined. The field is
not assigned to nor tested unless UNIV_DEBUG is defined.
Copy any data (currently table name and table index) that may be
destroyed after releasing the kernel mutex into internal cache's
storage.
This is done in efficient manner using ha_storage type and a given
string is copied only once into the cache's storage. Later additions of
the same string use the already stored string, thus allocating memory
only once per unique string.

Add a type that stores chunks of data in its own storage and avoids
duplicates. Supported methods:
ha_storage_create()
Allocates new storage object.
ha_storage_put()
Copies a given data chunk into the storage and returns pointer to the
copy. If the data chunk is already present, a pointer to the existing
object is returned and the given data chunk is not copied.
ha_storage_empty()
Clears (empties) the storage from all data chunks that are stored in it.
ha_storage_free()
Destroys a storage object. Opposite to ha_storage_create().
