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.

ha_innobase::add_index(): Do commit the transaction, because the error
handler (label err1) in mysql_alter_table() won't commit it as of now.
This was detected in a failure of type_bit_innodb.

now that all of InnoDB code is built from a single Makefile and it should
not be possible to build the modules with mutually incompatible options.

#define INSIDE_HA_INNOBASE_CC: Remove.

srv_sizeof_trx_t_in_ha_innodb_cc: Remove.

dict_table_get_low_noninlined(): Remove.  This function was unused.

Remove all _noninline functions.  Remove the _noninline suffix from
all function calls in ha_innodb.cc.

upd_get_n_fields(), upd_get_nth_field(): Add const qualifiers.

when allocating zero-filled memory.

Remove the variable parent_trx.

Call innobase_register_stmt() in order to work around a MySQL bug
in mysql_alter_table(), which, as of

ChangeSet@1.2482.61.2, 2007-06-07 16:37:15+02:00, joerg@trift2. +8 -0

commits the transaction before calling ha_innobase::add_index().
Without re-registering the statement, the ha_commit_stmt(thd)
in mysql_alter_table() would not invoke innobase_commit.

It should be committed by MySQL after all.  The error in mysql_alter_table()
will be worked around in r1584.

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.

row_merge_rename_index(): Really change the name of the index.  This was
broken in r1430.
