innobase_create_key_def(), row_table_got_default_clust_index(),
row_get_mysql_key_number_for_index(): Add a const qualifier.

dict_table_get_first_index(), dict_table_get_next_index(): Define
as a const-preserving macro.  Preserve the old function for UNIV_DEBUG,
but add a const qualifier to the parameter and cast away the constness.

row_ext_create(): After a memset() inside UNIV_DEBUG, flag the memory
uninitialized with UNIV_MEM_ALLOC().

and simplify error handling.

was broken in r1685.

innodb-index.test, innodb-index.result: Add a test for creating
a PRIMARY KEY on a column that contains a NULL value.

row_merge_create_temporary_table(): Add the parameter index_defs.

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).

ha_innobase::add_index(): Add the missing user_thd parameter to the
convert_error_code_to_mysql() call that was forgotten from r1686.

merge_index_field_struct: Add const qualifier to field_name.

merge_index_def_struct: Add const qualifier to name.

row_merge_build_indexes(): Improve the function comment.

row_merge_drop_table(): Remove bogus assertion ut_a(table->to_be_dropped).

goto err_exit.  The error handling should be rewritten.  Many of the
error messages contain parameters, but this code is only returning
the error number to MySQL.

as documented.  Do not translate the error code.

This function is still broken; we should probably use my_error() for
reporting errors.

The code for DB_CANNOT_DROP_FOREIGN_INDEX should have been
renumbered in r1494 (Merge revisions 1402:1493 from trunk).

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.

do not release and relock the data dictionary during initial preparations.

the index may be NULL when unfinished transactions are rolled back
after crash recovery.

before calling trx_lists_init_at_db_start().  This was broken in r1594.

row_mysql_read_true_varchar(), row_mysql_read_blob_ref(),
row_mysql_store_col_in_innobase_format(),
row_sel_convert_mysql_key_to_innobase(): Add const qualifiers.

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.

symbolic ones.

does not declare it unless MYSQL_SERVER is defined.

error code.  Apparently, the numeric error codes in MySQL 5.1 are changing.

implicit type conversion from void*.  Inlining is enabled in ha_innodb.cc
since r1587.

C++ requires explicit type casts when converting from void*, and *.ic files
are now inlined in ha_innodb.cc.

fil_space_get_by_id(), fil_space_get_by_name(): New inline functions, to
replace occurrences of the HASH_SEARCH() macro in fil0fil.c.  This should
improve readability.

This was broken in r1591.

about "row" being possibly uninitialized.

Add a const qualifier to lock_t*.

Fix some printouts.

row_ins_index_entry().  The added parameter (whether to check
foreign key constraints) was incorrectly passed as FALSE in r1591.

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.

Return DB_SUCCESS.  Do not release and reacquire kernel_mutex.

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.

dfield_is_null(), dfield_is_ext(), dfield_set_ext(), dfield_set_null():
New functions.

dfield_copy(), dfield_copy_data(): Add const qualifiers, fix in/out comments.

data_write_sql_null(): Use memset().

big_rec_field_t: Replace byte* data with const void* data.

ut_ulint_sort(): Remove.

upd_field_t: Remove extern_storage.

upd_node_t: Replace ext_vec, n_ext_vec with n_ext.

row_merge_copy_blobs(): New function.

row_ins_index_entry(): Add the parameter "ibool foreign" for suppressing
foreign key checks during fast index creation or when inserting into
secondary indexes.

btr_page_insert_fits(): Add const qualifiers.

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().

to rec_t*.  Remove the ut_ad(rec_offs_validate()), because this function
will be called from row0merge.c on a record that lacks the
REC_N_NEW_EXTRA_BYTES.
