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.
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.
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():

foreign key checks during fast index creation or when inserting into
secondary indexes.

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().
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.

all function calls in ha_innodb.cc.
comparing uninitialized values.
dict_mem_table_create(): Initialize table->version_number.
ins_node_create(): Initialize node->table_version_number.
row_create_prebuilt(): Initialize all fields. Initialize most fields
by memset(), so that any fields that are added will be initialized
automatically.
dict_truncate_index_tree(): Add the parameter space for specifying the
new tablespace identifier of a single-table tablespace that has been
recreated. When SYS_INDEXES.PAGE_NO == FIL_NULL, do not abort but
create the index tree.
fil_discard_tablespace(): Pass the return code from fil_delete_tablespace().
row_truncate_table_for_mysql(): Attempt to discard and recreate
single-table tablespaces. Reassign the tablespace identifier both in
the data dictionary (SYS_TABLES and SYS_INDEXES) and in the data
dictionary cache.
to tables.
dict_mem_table_add_col(): Add the parameter "heap" for temporary memory
allocation. Allow it and "name" to be NULL. These parameters are NULL
when creating dummy indexes.
dict_add_col_name(): Remove calls to ut_malloc() and ut_free().
dict_table_get_col_name(): Allow table->col_names to be NULL.
dict_table_add_system_columns(), dict_table_add_to_cache():
Add the parameter "heap".
buf_page_get_gen(). This saves one mutex operation per block request.
buf_page_get_gen(), various macros and functions: Add parameter zip_size.
btr_node_ptr_get_child(): Add parameter index.
fil_space_get_latch(): Add optional output parameter zip_size.
fil_space_get_zip_size(): Return 0 for space id==0, because the
system tablespace is never compressed.
fsp_header_init(): Remove the parameter zip_size.
ibuf_free_excess_pages(): Remove the parameter zip_size.
trx_rseg_t, trx_undo_t: Add field zip_size.
xdes_lst_get_next(): Remove, unused.
buf_pool_t: Remove n_frames, max_size, and blocks_of_frames.
The current buffer pool size is in curr_size.
buf_pool_init(): Remove parameter max_size.
buf_pool_get_max_size(), buf_pool_is_block(): Remove.
buf_block_align(): Do not assume that the buffer pool is allocated
in one chunk. Replace dependency on buf_pool->blocks_of_frames
with a call to buf_page_hash_get().
Do not break the latching order in TRUNCATE TABLE.
dict_truncate_index_tree(): Replace parameter rec_t* rec with
btr_pcur_t* pcur. Reposition pcur before calling btr_create().
sync_thread_add_level(): Remove the relaxation of the assertion added in r968.
rec_get_nth_field_offs_old(): Split from rec_get_nth_field_old().
rec_get_nth_field_old(): Reimplement as a constness-preserving macro.
dict_drop_index_tree(), dict_truncate_index_tree(): Note that rec is
an in/out parameter, as the B-tree root page number will be updated.
accessors returning pointers with macros that preserve const qualifiers.
In UNIV_DEBUG builds, retain the accessors and cast away constness there.
dfield_get_type(), dfield_get_data(), dtuple_get_nth_field(),
dict_table_get_nth_col(), dict_table_get_sys_col(): Implement as macro
unless #ifdef UNIV_DEBUG.
rec_get_nth_field(): Replace with rec_get_nth_field_offs() that does not
do pointer arithmetics. Implement rec_get_nth_field() as a macro.
and modify some functions to return const pointers. Add const qualifiers
to local variable declarations or casts to remove the const qualifier
in those places where write access is needed.
with page_get_page_no() and page_get_space_id(). We want to avoid
buf_block_align() calls, and the page_no and space_id are now stamped
on the pages early on.
dict_load_foreigns(): Enclose in #ifndef UNIV_HOTBACKUP.
fil_extend_tablespaces_to_stored_len(): Pass zip_size to fil_read().
buf_page_init_for_backup_restore(): Add parameter zip_size.
Enclose the declaration in buf0buf.h in #ifdef UNIV_HOTBACKUP.
recv_apply_log_recs_for_backup(): Replace the local variable "page"
with the local variable "block". Add local variable zip_size.
of externally stored columns to REC_1BYTE_OFFS_LIMIT (128) bytes.
TODO: only store BTR_EXTERN_FIELD_REF_SIZE (20) bytes with the record,
and store the entire column externally. (Bug #22496)
dict_col_t::min_prefix: Remove.
of externally stored columns to 108 bytes when possible.
This will unmask a bug in the handling of BLOBs on compressed tablespaces,
especially of small page sizes. Apparently, the locally stored part must
be less than 235 bytes in size for the bug to occur.
dict_col_struct: Add field min_prefix.
dict_index_build_internal_non_clust(): Adjust min_prefix.
dict_load_table(): Initialize table->flags with zip_size.
