DB_PRIMARY_KEY_IS_NULL: New error code, mapped to ER_PRIMARY_CANT_HAVE_NULL.
row_merge_read_clustered_index(): Replace the parameter "table" with the
two parameters "old_table" and "new_table". Detect NULL values of columns
that are supposed to be NOT NULL.
row_merge_col_prtype(): New auxiliary function, used by
row_merge_create_temporary_table() to flag NOT NULL any columns
contained in an added PRIMARY KEY.
innobase_copy_index_field_def(): Remove parameter heap. The field->name
will not be deallocated before the copied index has been added to the
data dictionary cache.
innobase_copy_index_def(): Add const qualifier to dict_index_t*.
Add an assertion !dict_index_is_clust(index).

row_merge_build_indexes(): Improve the function comment.
row_merge_drop_table(): Remove bogus assertion ut_a(table->to_be_dropped).
row_merge_buf_create_low(): Swap the parameters max_tuples and buf_size,
because the callers had them swapped. Add debug assertions about
these parameters.
row_merge_buf_empty(): Return the emptied buffer. In some cases, the
buffer may be relocated.

row_sel_convert_mysql_key_to_innobase(): Document that the first parameter
is in/out.
the data dictionary locked across the operations.
dict_table_decrement_handle_count(), row_prebuilt_free(): Add the flag
dict_locked, to prevent the acquisition of dict_sys->mutex.
innobase_rename_table(): Rename commit_flag to lock_and_commit,
and do not acquire dict_sys->mutex or flush the log unless the flag is set.
Remove bogus comment about utility threads, because the threads will
be waken up by the upper-level function ha_innobase::rename_table().
ha_innobase::add_index(): After creating a primary key, hold dict_sys->mutex
across all dictionary operations.
be set always.
trx_rollback_active(): Split from trx_rollback_or_clean_all_without_sess().
row_undo_dictionary(): Do not return a value. Assert that all operations
succeed.
row_merge_drop_index(): Remove bogus comment about void return value.
trx_dummy_sess: Move the declaration from trx0roll.h to trx0trx.h,
because the variable is defined in trx0trx.c.
Some things still fail in innodb-index.test, and there seems to be
a race condition (data dictionary lock wait) when running with --valgrind.
dfield_t: Add an "external storage" flag, dfield->ext.

btr_cur_add_ext(), upd_ext_vec_contains(): Remove.
dfield_print_also_hex(), dfield_print(): Replace if...else if with switch.
Observe dfield_is_ext().
Because row_drop_table_for_mysql_no_commit() checks with dict_load_table()
if the table was successfully dropped, we cannot pass table->name to it.
row_merge_drop_table(): Pass a copy of table->name to
row_drop_table_for_mysql().
row_prebuilt_free(): Do not dereference prebuilt->table->name after a
successful invocation of row_add_table_to_background_drop_list(). The
table object may be freed at any time. Remove the debug message
"Dropping table".
occur in mysql-test-run, but mysql-test-run reports some warnings for
some tests and incorrect results for innodb-index.test.
innobase_start_trx_and_assign_read_view(): Use thd instead of current_thd.
ha_innobase::add_index(): Use ha_thd() instead of current_thd.
Commit the transaction at the end.

broken in r1430.
during fast index creation.

ut_print_namel(): Check if the name starts with TEMP_TABLE_PREFIX.
innobase_rename_table(): Print all names with ut_print_name().
row_prebuilt_free(): Replace assert() with ut_a().
comparing uninitialized values.
dict_mem_table_create(): Initialize table->version_number.
ins_node_create(): Initialize node->table_version_number.

by memset(), so that any fields that are added will be initialized
automatically.

row_merge_buf_write(): Add an assertion about buf->total_size.
row_merge_heap_create(), row_merge_read_rec(), row_merge_insert_index_tuples():
offsets needs to be 1 + REC_OFFS_HEADER_SIZE + n_fields. Previously, we
allocated one element too little.
row_merge_blocks(): Use goto instead of break in the AT_END argument
of ROW_MERGE_WRITE_GET_NEXT.
single os_mem_alloc_large() call. The function mem_alloc() that was
used previously allocates unaligned memory.
row_merge_blocks(): Replace block1, block2, block3 with a single array.
Replace buf1, buf2, buf3 with buf[3]. Replace b1..b3 with b0..b2.
Replace mrec1,2 with mrec0,1. Replace offsets1,2 with offsets0,1.
row_merge(), row_merge_sort(): Replace block1, block2, block3 with a
single array.
The creation of the primary key does not work. We will have to flag
externally stored columns and copy the externally stored part from
the old table.
row_build_index_for_mysql(): Rename to row_merge_build_indexes().
Move from row0mysql.c to row0merge.c.
Remove private declarations from row0merge.h. Make many functions static

rec_get_converted_size_comp(): Return also extra_size.
UT_SORT_FUNCTION_BODY(): Remove reference to an obsolete test program.
row_rec_to_index_entry_low(): New function.
row0merge.c: Implement merge sort based on file streams instead of
fixed-size blocks. Sort the small blocks as arrays of dfield_t*,
because it is faster than invoking rec_get_offsets() for every
comparison.
row_merge_mark_prebuilt_obsolete(): Rename to row_prebuilt_table_obsolete()
and move from row0merge.c to row0mysql.c. Remove the parameter trx.
row_merge_print_table(): Remove.
row_remove_indexes_for_mysql(): Rename to row_merge_drop_indexes(),
move from row0mysql.c to row0merge.c and make the return type void.
row_merge_remove_index(): Rename to row_merge_drop_index() and make
the return type void.
Replace row0merge.h with row0mysql.h.
Remove redundant test trx->dict_operation_lock_mode == 0.
Fix typos in comments.

btr_page_reorganize_low(), page_zip_reorganize(): Do not update the insert
buffer bitmap. Instead, document that callers will have to take care of it,
and adapt the callers.
btr_compress(): On error, reset the insert buffer free bits.
btr_cur_insert_if_possible(): Do not modify the insert buffer bitmap.
btr_compress(), btr_cur_optimistic_insert(): On compressed pages,
reset the insert buffer bitmap. Document why.
btr_cur_update_alloc_zip(): Document why it is necessary and sufficient
to reset the insert buffer free bits.
btr_cur_update_in_place(), btr_cur_optimistic_update(),
btr_cur_pessimistic_update(): Update the free bits in the same
mini-transaction. Document that the mini-transaction must be
committed before latching any further pages. Verify that this
is the case in all execution paths.
row_ins_sec_index_entry_by_modify(), row_ins_clust_index_entry_by_modify(),
row_undo_mod_clust_low(): Because these functions call
btr_cur_update_in_place(), btr_cur_optimistic_update(), or
btr_cur_pessimistic_update(), document that the mini-transaction must be
committed before latching any further pages. Verify that this is the case
in all execution paths.
was broken in one of the earlier cleanups.
row_merge_block_merge(): Remove the variable "selected". Clear the record
count of new_block1 and new_block2. Anticipate the right return values
from row_merge_cmp().
in r1445. They are needed after all, but apparently the tests do not
actually verify that the records are sorted. (Also, a buffer overflow
will occur in index_merge_innodb.test if MERGE_BLOCK_SIZE is made smaller.)
dict_index_is_unique(): New function.
row_merge_rec_fits_to_block(), row_merge_store_rec_to_block():
Add const qualifiers to rec, offsets.
row_merge_select(): Rename to row_merge_cmp(), simplify the interface.

and os_file_write(), and return DB_CORRUPTION when they fail. Minor cleanup.
row_mege_insert_index_tuples(): Use a shared heap for dtuple and rec.
Use fewer gotos.
row_merge_sort_linked_list_in_disk(): Free the merge blocks at error exit.
row_merge_read(), row_merge_write(): Add UNIV_LIKELY hints.
row_merge_sort_linked_list_in_disk(): Reduce the scope of many variables.

Avoid references to MERGE_BLOCK_SIZE.
Improve the language of some comments.
row_merge_insert_index_tuples(), row_merge_sort_linked_list_in_disk():
Make the offset a ulint.
row_merge_read(), row_merge_write(): Helper functions. Return the
status of os_file_read() and os_file_write(). TO DO: check the status
in the callers.
innobase_create_temporary_tablename(): Add static qualifier. Allocate
the memory from heap. Return a fixed identifier.
ha_innobase::add_index(): Allocate all memory from a single heap.
Simplify error handling. Use a fixed prefix for temporary table names,
because only one add_index() can be active for a given table.
mem_heap_empty_noninline(): New function, to be called from ha_innodb.cc.
row_build_index_for_mysql(): Remove the parameter new_primary.
