marko	137cf961e4	branches/zip: Fix some bugs in the crash recovery of compressed tablespaces. fil_node_open_file(): Set node->size correctly for compressed tablespaces. fsp_header_write_space_id(): Rename to fsp_header_write_fields(), add parameter zip_size. fil_io(): Add UNIV_UNLIKELY hints to assertion-like tests.	20 years ago
marko	af445f4b77	branches/zip: fsp_try_extend_data_file(): Extend the data file by one megabyte at a time, no matter what the compressed page size is.	20 years ago
marko	5837f75150	branches/zip: Cleanup suggested by Osku. ut_is_2pow(): New function for testing if a number is zero or a power of two. Use this function instead of bitwise arithmetics or ut_2_power_up() where possible.	20 years ago
marko	49d252397a	branches/zip: Remove remaining occurrences of XDES_DESCRIBED_PER_PAGE. mlog_parse_string(): Remove an off-by-one error in an assertion. fil_extend_space_to_desired_size(): fsp_header_get_free_limit(), fsp_try_extend_data_file(): Replace UNIV_PAGE_SIZE with the actual page size. PAGE_ZIP_MIN_SIZE: New constant, to be used in assertions. FSP_SEG_INODES_PER_PAGE: Add parameter zip_size. fsp_seg_inode_page_get_nth_inode(), fsp_seg_inode_page_find_used(), fsp_seg_inode_page_find_free(): Add parameter zip_size.	20 years ago

marko	1dd4d56863	branches/zip: Write compressed pages to disk. os_aio_simulated_handle(): Temporarily disable os_file_check_page_trailers(), which cannot be invoked on compressed pages. dict_table_add_system_columns(): New function, split from dict_table_add_to_cache(). mlog_parse_index(): Add system columns to the dummy table and identify DB_TRX_ID and DB_ROLL_PTR in the dummy index. buf_LRU_get_free_block(): Note that page_zip->data should be allocated from an aligned memory pool. buf_flush_buffered_writes(): Write compressed pages to disk. buf_flush_post_to_doublewrite_buf(): Copy compressed pages to the doublewrite buffer. Zero fill any excess space. buf_flush_init_for_writing(): Treat all compressed pages the same. buf_read_page_low(): Read compressed pages from disk. buf_page_io_complete(): Process compressed pages. trx_sys_doublewrite_init_or_restore_page(): Process compressed pages. mlog_write_initial_log_record_fast(): Enable a debug printout #ifdef UNIV_LOG_DEBUG. fsp_header_init(), fsp_fill_free_list(): Pass the compressed page size to buf_page_create(). page_zip_compress_write_log(): Flatten the if-else if-else logic. page_zip_parse_write_blob_ptr(): Do not test page_zip if page==NULL. page_zip_parse_write_node_ptr(): Do not test page_zip if page==NULL. Invoke mlog_close() correctly. row_sel_store_row_id_to_prebuilt(): Add UNIV_UNLIKELY hint to an assertion-like test.	20 years ago
marko	ed354ce80c	branches/zip: Minor cleanup and bug fixes btr_page_reorganize_low(): Rename new_page to temp_page. btr_store_big_rec_extern_fields(): FIL_PAGE_TYPE is 2 bytes, not 4. buf_page_init(), buf_page_create(), buf_read_page_low(), buf_page_init_for_read(): Add parameter zip_size. buf_page_init_for_backup_restore(), recv_apply_log_recs_for_backup(): Enclose in #ifdef UNIV_HOTBACKUP. Enclose some debug code in #ifdef UNIV_LOG_REPLICATE. page_zip_write_header_log(): Replace page_zip with a pointer to the uncompressed page. page_zip_write_rec(): Relax an assertion about blob_no + n_ext. page_copy_rec_list_to_created_page_write_log(): Allow logging to be disabled.	20 years ago
marko	6dd1d8c4fe	branches/zip: Write the compressed page size to SYS_TABLES.TYPE 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.

marko	12050c5c1c	branches/zip: Prepare for in-place updates of B-tree node pointers, BLOB pointers, trx_id, and roll_ptr. btr_empty(), btr_create(), page_create(): Add parameter "index", as some index information will be encoded on the compressed page. Define REC_NODE_PTR_SIZE as 4. Allow btr_page_reorganize() and btr_page_reorganize_low() to fail. Define the error code DB_ZIP_OVERFLOW. Make row_ins_index_entry_low() static. page0zip: Encode the index, log reorganized records, and store uncompressed fields separately from the compressed data stream.	20 years ago
