marko	2ddbc912e7	branches/zip: Silence most GCC 4.2.1 warnings about const pointers. For some reason, GCC 4.2.1 ignores casts (for removing constness) in calls to inline functions. page_align(), ut_align_down(): Make the parameter const void*, but still return a non-const pointer. This is ugly, but these functions cannot be replaced with a const-preserving macro in a portable way, given that the pointer argument is not always pointing to bytes. buf_block_get_page_zip(): Implement as a const-preserving macro. buf_frame_get_page_zip(), buf_block_align(): Add const qualifiers. lock_rec_get_prev(): Silence GCC 4.2.1 warnings. mlog_write_initial_log_record(), mlog_write_initial_log_record_fast(), mtr_memo_contains(): Add const qualifier to the pointer. page_header_get_ptr(): Rewrite as page_header_get_offs(), and implement as a macro that calls this function.	18 years ago

marko	463aaf28ba	branches/zip: Avoid memory fragmentation when adding column definitions to tables. dict_mem_table_add_col(): Add the parameter "heap" for temporary memory allocation. Allow it and "name" to be NULL. These parameters are NULL when creating dummy indexes. dict_add_col_name(): Remove calls to ut_malloc() and ut_free(). dict_table_get_col_name(): Allow table->col_names to be NULL. dict_table_add_system_columns(), dict_table_add_to_cache(): Add the parameter "heap".	19 years ago

marko	fbe4fe6022	branches/zip: Remove the casts introduced in r920 and r925. Replace the 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.	19 years ago
marko	469a27ac2a	branches/zip: Replace buf_frame_align() with page_align(), page_offset(), ut_align_down(), or ut_align_offset().	19 years ago

marko	38e09b2fea	branches/zip: Merge revisions 720:765 from trunk and reindent the code as per revisions r763:765.	20 years ago
marko	b355bd0fbc	branches/zip: Fix some crash recovery bugs. dict_load_table(): Initialize table->flags with zip_size. mlog_parse_nbytes(), mlog_parse_string(): Add parameter page_zip and write the changes also to the compressed page if one is specified. Assert that these functions are not called on FIL_PAGE_INDEX pages. buf_page_io_complete(): Replace block->frame with frame where appropriate. recv_parse_or_apply_log_rec_body(): Add ut_a(!page_zip) where appropriate. page_parse_delete_rec_list(): Add parameter page_zip.	20 years ago
marko	508c578ce4	mlog_parse_index(): Remove an off-by-one error in the bounds check that would cause the crash recovery of MLOG_COMP_PAGE_REORGANIZE to fail. (Bug #20855)	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

Remove trailing white space. mlog_log_string(): Remove trailing white space. rec_set_field_extern_bits(): Remove parameter mtr, as the write will either occur in the heap, or it will be logged at a higher level. recv_parse_or_apply_log_rec_body(), page_zip_write_header(): Add log record type MLOG_ZIP_WRITE_HEADER. page_header_set_field(): Pass mtr=NULL to page_zip_write_header(). page_header_reset_last_insert(): Pass mtr to page_zip_write_header(). btr_page_set_index_id(), btr_page_set_level(), btr_page_set_next(), btr_page_set_prev(): Pass mtr to page_zip_write_header(). row_upd_rec_sys_fields(): Pass mtr=NULL to page_zip_write_trx_id() and page_zip_write_roll_ptr(), since the write will be logged at a higher level. page_zip_write_header(): Add parameter mtr. page_zip_write_header_log(): New function. Remove rec_set_nth_field_extern_bit(). Make rec_set_nth_field_extern_bit_old() static.

marko	1b7710af93	branches/zip: Implement the compression of BLOB columns. This has not been extensively tested yet, because some other part of the code breaks in "ibtestblob". btr_free_page_low(): Add parameters "space" and "page_no", because they are omitted from compressed BLOB pages. btr0cur.c: Implement the compression and decompression of BLOB columns, enabled at compile-time (#define ZIP_BLOB TRUE) for now. btr_rec_free_externally_stored_fields(), btr_copy_externally_stored_field(): Made static mlog_log_string(): New function, split from mlog_write_string(), allows to avoid a dummy memcpy() of compressed BLOB pages.	20 years ago
