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.
Replace all page_t* parameters with buf_block_t*, and replace many
rec_t* parameters with heap_no. This eliminates also many
rec_get_heap_no() calls, which became more expensive with the
introduction of ROW_FORMAT=COMPACT in MySQL/InnoDB 5.0.3.
page_rec_get_heap_no(), lock_get_min_heap_no(): New functions.
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.
and to the file space header (FSP_PAGE_ZIP_SIZE, renamed from
FSP_LOWEST_NO_WRITE).
fil_space_struct: Add zip_size.
dict_table_struct: Embed zip_size in flags.
dict_table_zip_size(): Infer zip_size from table->flags.
dict_sys_tables_get_zip_size(): Read zip_size from SYS_TABLES.TYPE.
fil_space_get_zip_size(): Read zip_size from the file space header.
Add the redo log entry type MLOG_ZIP_FILE_CREATE.
of clustered indexes. Previously, parts of the code assumed that these
columns would exist on all leaf pages. Simplify the update-in-place of
these columns.
Add inline function dict_index_is_clust() to replace all tests
index->type & DICT_CLUSTERED.
Remove the redo log entry types MLOG_ZIP_WRITE_TRX_ID and
MLOG_ZIP_WRITE_ROLL_PTR, because the modifications to these columns
are covered by logical logging.
Fuse page_zip_write_trx_id() and page_zip_write_roll_ptr() into
page_zip_write_trx_id_and_roll_ptr().
page_zip_dir_add_slot(), page_zip_available(): Add flag "is_clustered",
so that no space will be reserved for TRX_ID and ROLL_PTR on leaf pages
of secondary indexes.
page_zip_apply_log(): Flag an error when val==0 is encoded with two bytes.
page_zip_write_rec(): Add debug assertions that there is enough space
available for the entry before copying the data bytes of the record.
