    MDEV-12353: Replace MLOG_*LIST_*_DELETE and MLOG_*REC_DELETE · 2a77b2a5
    Marko Mäkelä authored
    No longer write the following redo log records:
    MLOG_COMP_LIST_END_DELETE, MLOG_LIST_END_DELETE,
    MLOG_COMP_LIST_START_DELETE, MLOG_LIST_START_DELETE,
    MLOG_REC_DELETE,MLOG_COMP_REC_DELETE.
    
    Each individual deleted record will be logged separately
    using physical log records.
    
    page_dir_slot_set_n_owned(),
    page_zip_rec_set_owned(), page_zip_dir_delete(), page_zip_clear_rec():
    Add the parameter mtr, and write redo log.
    
    page_dir_slot_set_rec(): Remove. Replaced with lower-level operations
    that write redo log when necessary.
    
    page_rec_set_n_owned(): Replaces rec_set_n_owned_old(),
    rec_set_n_owned_new().
    
    rec_set_heap_no(): Replaces rec_set_heap_no_old(), rec_set_heap_no_new().
    
    page_mem_free(), page_dir_split_slot(), page_dir_balance_slot():
    Add the parameter mtr.
    
    page_dir_set_n_slots(): Merge with the caller page_dir_split_slot().
    
    page_dir_slot_set_rec(): Merge with the callers page_dir_split_slot()
    and page_dir_balance_slot().
    
    page_cur_insert_rec_low(), page_cur_insert_rec_zip():
    Suppress the logging of lower-level operations.
    
    page_cur_delete_rec_write_log(): Remove.
    
    page_cur_delete_rec(): Do not tolerate mtr=NULL.
    
    rec_convert_dtuple_to_rec_old(), rec_convert_dtuple_to_rec_comp():
    Replace rec_set_heap_no_old() and rec_set_heap_no_new() with direct
    access that does not involve redo logging.
    
    mtr_t::memcpy(): Do allow non-redo-logged writes to uncompressed pages
    of ROW_FORMAT=COMPRESSED pages.
    
    buf_page_io_complete(): Evict the uncompressed page of
    a ROW_FORMAT=COMPRESSED page after recovery. Because we no longer
    write logical log records for deleting index records, but instead
    write physical records that may refer directly to the compressed
    page frame of a ROW_FORMAT=COMPRESSED page, and because on recovery
    we will only apply the changes to the ROW_FORMAT=COMPRESSED page,
    the uncompressed page frame can be stale until page_zip_decompress()
    is executed.
    
    recv_parse_or_apply_log_rec_body(): After applying MLOG_ZIP_WRITE_STRING,
    ensure that the FIL_PAGE_TYPE of the uncompressed page matches the
    compressed page, because buf_flush_init_for_writing() assumes that
    field to be valid.
    
    mlog_init_t::mark_ibuf_exist(): Invoke page_zip_decompress(), because
    the uncompressed page after buf_page_create() is not necessarily
    up to date.
    
    buf_LRU_block_remove_hashed(): Bypass a page_zip_validate() check
    during redo log apply.
    
    recv_apply_hashed_log_recs(): Invoke mlog_init.mark_ibuf_exist()
    also for the last batch, to ensure that page_zip_decompress() will
    be called for freshly initialized pages.
