ha_innobase::add_index(): Add assertions about !trx->sync_cb and
!trx->dict_redo_list. Remove a bogus comment. Replace
row_lock_table_for_merge() with row_merge_lock_table().
row_merge_lock_table(): Renamed from row_lock_table_for_merge()
and moved from row0mysql.c to row0merge.c. Always lock the table in
the mode LOCK_X. Call que_graph_free() in order not to leak memory.
freed with UNIV_MEM_FREE(). Before this change, the memory
freed by mem_heap_empty() was not completely flagged free
in UNIV_DEBUG_VALGRIND builds. After this change, Valgrind
will hopefully catch all errors caught by UNIV_MEM_DEBUG.
FOREIGN KEY constraints. At the moment, MySQL will rebuild the entire
table and indexes when such constraints are added or removed, even though
the constraints do not affect the storage format of the data.
innodb-index.test: Add some test cases for FOREIGN KEY constraints.
row_merge_rename_tables(): New function,
adapted from row_rename_table_for_mysql().
ha_innobase::add_index(): Use row_merge_rename_tables().
have been set.
ha_innobase::add_index(), ha_innobase::prepare_drop_index(),
ha_innobase::final_drop_index(): Return HA_ERR_WRONG_COMMAND if
newraw or innodb_force_recovery have been set.
mem_heap_zalloc() and mem_zalloc(), because calloc() in the C runtime
library takes two size parameters, not one.
mem_heap_zalloc(): Add debug assertions. Document that the return value
is never NULL.
(PRIMARY KEY or UNIQUE INDEX on NOT NULL columns).
innodb-index.test: Remove the --replace_regex directives. Replace correct
values to the "Duplicate entry" messages. This will cause the test to
fail until we somehow return the duplicate key values to MySQL.
Add test cases for creating or dropping UNIQUE INDEX or PRIMARY KEY.
innobase_copy_index_def(): Allow the function to copy a clustered index
definition to a secondary one (UNIQUE INDEX).
innobase_create_key_def(): Check the NOT NULL flag from the correct
place. Copy the clustered index if it is a UNIQUE INDEX.
ha_innobase::prepare_drop_index(): Refuse to drop the clustered index.
ha_innobase::add_index(), ha_innobase::prepare_drop_index():
Remove the redundant thd_test_options() calls.
The options are tested in check_trx_exists().
ha_innobase::prepare_drop_index(): key cannot be NULL; remove the tests.
Move the condition for checking foreign keys outside of the loop.
Remove the redundant error log printout about foreign key dependency.
Remove the unused constant DICT_NOT_READY.
Make dict_index_t::type a bit-field, and move it next to other bit-fields.
Add a const qualifier to dict_index_t::name.
It was only set by ha_innobase::prepare_drop_index(), which can return
the appropriate MySQL error code (HA_ERR_DROP_INDEX_FK) directly.
ha_innobase::add_index(): Correct the function comment.
ha_innobase::prepare_drop_index(): Correct the function comment.
Return MySQL error codes directly.
ha_innobase::final_drop_index(): Correct the function comment.
row_merge_buf_add(): Add a prefetch instruction to row->fields.
Eliminate a variable from the copying loop, and move the termination
condition to the end of the loop.
row_merge_build_indexes(): Remove the second call to
trx_start_if_not_started().
trx_t: Change the type of error_info from void* to const dict_index_t*.
trx_get_error_info(): Add const qualifier to trx_t*. Make this an
inline function.
(merging branches/fast-index-creation):
row_truncate_table_for_mysql(), row_drop_table_for_mysql_no_commit():
Let ut_print_name() output to ef instead of stderr.
key name "PRIMARY". If the table has a generated clustered index,
also check for a UNIQUE INDEX containing no NULL columns.
innobase_create_index_def(): Add the parameter key_primary.
innobase_create_key_def(): Check if the first index is a UNIQUE index
consisting of NOT NULL columns.
Fixing this bug revealed another one: FOREIGN KEY constraints
will be lost when a PRIMARY KEY is created. This is the reason why
innodb.test will fail.
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_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.
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_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.
