Corrected some comments.
os_file_create_tmpfile(): Remove the implementation from InnoDB Hot Backup.
In InnoDB Hot Backup builds, do not define dict_casedn_str(),
which is invoked in fil_load_single_table_tablespace() on
Windows. This function depends on innobase_casedn_str() and
my_casedn_str().
Define btr_check_node_ptr() and data_error only #ifdef UNIV_DEBUG.
They are only being used in ut_ad() assertions.
Replace the occurrences of the type uint with ulint, because InnoDB
Hot Backup does not define any uint data type.
Disable lock_validate() in InnoDB Hot Backup builds.
Disable some unused static variables of srv0srv.c in InnoDB Hot Backup builds.
Disable some srv_table_...() functions in InnoDB Hot Backup builds.
Disable some unused static variables in srv0start.c in
InnoDB Hot Backup builds.
Disable io_handler_thread() in InnoDB Hot Backup builds.
Disable srv_calc_low32() and srv_calc_high32() in InnoDB Hot Backup builds
to avoid warnings about unused functions.
In fil_node_open_file(), avoid bogus assertions in InnoDB Hot Backup builds.
In fil_load_single_table_tablespace(), remove the call to dict_casedn_str(),
as it depends on MySQL code.
Copy the code of recv_reset_log_files_for_backup() from InnoDB Hot Backup.
Disable innobase_mysql_cmp(), cmp_whole_field(), cmp_data_data_slow(),
cmp_dtuple_rec_with_match() and cmp_rec_rec_with_match()
in InnoDB Hot Backup builds, as they depend on MySQL code.
Adapt dtype_set_mblen() and dtype_get_fixed_size() for InnoDB Hot Backup
builds, assuming that they will only be called on system tables, which
do not contain multi-byte characters.
Disable the static functions row_ins_set_exclusive_rec_lock() and
row_ins_dupl_error_with_rec() in InnoDB Hot Backup builds
to avoid warnings about unused functions.
In row_sel_field_store_in_mysql_format(), disable some UTF-8 related
assertions #ifndef UNIV_RELEASE_NOT_YET_STABLE.
new tablespaces created from now on.
btr_store_big_rec_extern_fields(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_BLOB.
buf_page_print(): Decode FIL_PAGE_TYPE. Replace if-else with switch().
buf_page_create(): Set FIL_PAGE_PREV, FIL_PAGE_NEXT and FIL_PAGE_TYPE.
trx_sysf_create(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_TRX_SYS.
Initialize TRX_SYS_RSEG_SPACE.
FIL_PAGE_TYPE: Document that the field cannot be relied on in older
versions of MySQL/InnoDB. Add new type codes.
ibuf_bitmap_page_init(): Document that the rest of the page is uninitialized.
ibuf_add_free_page(): Log the setting of FIL_PAGE_TYPE.
fsp_header_init(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_FSP_HDR.
Initialize FSP_NOT_USED.
fsp_fill_free_list(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_XDES.
fsp_alloc_seg_inode_page(): Set FIL_PAGE_TYPE to FIL_PAGE_INODE.
fseg_create_general(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_SYS.
adaptive hash index for a B-tree page. (Bug #16582)
btr_search_drop_page_hash_index(): Retry the operation if a hash index
with different parameters was built meanwhile. Add diagnostics for the
case that hash node pointers to the page remain. This fix is from Heikki.
btr_search_info_update_hash(), btr_search_info_update_slow():
Document the parameter "info" as in/out.
Note that buf_block_t::index should be protected by btr_search_latch
or an s-latch or x-latch on the index page.
btr_search_drop_page_hash_index(): Read block->index while holding
btr_search_latch and use the cached value in the loop. Remove some
redundant assertions.
