marko	a3d72680f6	branches/zip: Add const qualifiers to read-only pointers. 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.	19 years ago
marko	223cb22210	branches/zip: Remove some more casts. dict_index_get_nth_col_pos(), dict_index_get_sys_col_pos(), dict_index_get_n_fields(), fil_page_get_type(): Add const qualifier to parameter. dict_index_get_nth_field(): Implement as a macro unless #ifdef UNIV_DEBUG.	19 years ago
marko	9d2146e431	branches/zip: Replace FIL_PAGE_ZBLOB_SPACE_ID and FIL_PAGE_ZBLOB_DATA with FIL_PAGE_ARCH_LOG_NO_OR_SPACE_ID and FIL_PAGE_DATA. The doublewrite buffer needs to read the space_id in order to determine the type of the page. Because FIL_PAGE_TYPE could contain garbage in MySQL/InnoDB 5.0 and earlier versions, we cannot trust fil_page_get_type(). Instead, we have to always store the space_id at the same location. This modification wastes 12 bytes per compressed BLOB page (1.2% on 1-kilobyte pages).	19 years ago
marko	0d5392310b	branches/zip: fil_space_truncate_start(): Fix an incorrect assertion, disable unless #ifdef UNIV_LOG_ARCHIVE.	20 years ago
marko	be7add3b56	branches/zip: Add parameter zip_size to fil_io(). fil_read(), fil_write(): Make these inlined functions in fil0fil.c. fil_write_lsn_and_arch_no_to_file(): Remove the parameter space_id and note that this function is to be called on the system tablespace, which is uncompressed.	20 years ago
marko	fefd14cbbc	branches/zip: Merge revisions 536:558 from trunk.	20 years ago
marko	f258491a26	branches/zip: Minor improvements. Introduce FIL_PAGE_ZBLOB_DATA as a synonym for FIL_PAGE_FILE_FLUSH_LSN. btr_store_big_rec_extern_fields(): Make the assertion about dict_table_zip_size() more accurate. buf_LRU_get_free_block(), buf_block_alloc(): Add parameter zip_size. buf_calc_zblob_page_checksum(): Remove. Replace with page_zip_calc_checksum(). buf_page_init(): Remove parameter zip_size. buf_page_io_complete(): Add a placeholder for handling compressed pages. trx_doublewrite_page_inside(): Remove redundant function. page_zip_write_rec(): Relax an overly tight assertion about blob_no.	20 years ago
marko	7bd3aca4ad	branches/zip: Prepare for writing compressed and reading pages. buf_page_print(): Print also compressed pages. Add parameter zip_size. buf_flush_init_for_writing(): Stamp the fields on a compressed B-tree index page. Add the header field FIL_PAGE_ZBLOB_SPACE_ID as an alias of FIL_PAGE_PREV. page_zip_calc_checksum(): New function. page_zip_compress(): Avoid copying the fields that are written in buf_flush_init_for_writing(). page_zip_header_cmp(): New function for comparing those fields of the page header that will not be written in buf_flush_init_for_writing().	20 years ago
marko	121623c1b4	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. Add the redo log entry type MLOG_ZIP_FILE_CREATE.	20 years ago
marko	f4c776f518	branches/zip: Initial steps towards disk-based storage of compressed pages. dict_mem_table_create(): Account for DICT_TF_COMPRESSED in a debug assertion. btr_store_big_rec_extern_fields(), btr_free_externally_stored_field(), btr_copy_externally_stored_field(): Implement the disk format for compressed BLOB pages. btr_copy_externally_stored_field(): Improve error reporting and handling when decompressing BLOB pages. buf_flush_init_for_writing(), buf_page_is_corrupted(), buf_page_print(): Account for compressed BLOB pages (FIL_PAGE_TYPE_ZBLOB). buf_calc_zblob_page_checksum(): New function.	20 years ago
marko	f40121415d	branches/zip: Merge revisions 200:236 from trunk.	20 years ago
osku	c307820962	Import 5.0 code.	20 years ago
