Satya B	963d2d432b	Applying InnoDB Plugin 1.0.5 snapshot, part 6 ... From revision r5748 to r5783 Detailed revision comments: r5748 | marko | 2009-09-03 06:05:44 -0500 (Thu, 03 Sep 2009) | 1 line branches/zip: MLOG_MULTI_REC_END: Correct the comment. r5751 | marko | 2009-09-03 09:36:15 -0500 (Thu, 03 Sep 2009) | 7 lines branches/zip: row_merge(): Remove a bogus debug assertion that was triggered when creating an index on an empty table. row_merge_sort(): Add debug assertions and comments that justify the loop termination condition. The bogus assertion ut_ad(ihalf > 0) was reported by Michael. r5752 | marko | 2009-09-03 09:55:51 -0500 (Thu, 03 Sep 2009) | 10 lines branches/zip: recv_recover_page_func(): Write the log sequence number to the compressed page, if there is one. Previously, the function only wrote the LSN to the uncompressed page. It is not clear why recv_recover_page_func() is updating FIL_PAGE_LSN in the buffer pool. The log sequence number will be stamped on the page when it is flushed to disk, in buf_flush_init_for_writing(). I noticed this inconsistency when analyzing Issue #313, but this patch does not fix it. That is no surprise, since FIL_PAGE_LSN should only matter on disk files, not in the buffer pool. r5775 | calvin | 2009-09-07 16:15:05 -0500 (Mon, 07 Sep 2009) | 13 lines branches/zip: Build InnoDB on Windows with UNIV_HOTBACKUP The changes are non-functional changes for normal InnoDB, but needed for building the Hot Backup on Windows (with UNIV_HOTBACKUP defined). - Define os_aio_use_native_aio for HB. - Do not acquire seek mutexes for backup since HB is single threaded. - Do not use srv_flush_log_at_trx_commit for HB build rb://155 Approved by: Marko r5777 | marko | 2009-09-08 10:50:25 -0500 (Tue, 08 Sep 2009) | 2 lines branches/zip: Remove BUF_LRU_INITIAL_RATIO, which should have been removed together with buf_LRU_get_recent_limit(). r5779 | marko | 2009-09-09 01:17:19 -0500 (Wed, 09 Sep 2009) | 2 lines branches/zip: buf_page_peek_if_too_old(): Make the bitmasking work when buf_pool->freed_page_clock is wider than 32 bits. r5780 | marko | 2009-09-09 01:50:50 -0500 (Wed, 09 Sep 2009) | 1 line branches/zip: ut_time_ms(): Return ulint, not uint. r5782 | marko | 2009-09-09 02:00:59 -0500 (Wed, 09 Sep 2009) | 2 lines branches/zip: buf_page_peek_if_too_old(): Silence a compiler warning that was introduced in r5779 on 32-bit systems. r5783 | marko | 2009-09-09 02:25:00 -0500 (Wed, 09 Sep 2009) | 1 line branches/zip: buf_page_is_accessed(): Correct the function comment.	2009-10-08 18:22:21 +05:30

Satya B	abfdf76bbf	Applying InnoDB Plugin 1.0.5 snapshot, part 4 ... From revision r5703 to r5716 Detailed revision comments: r5703 | marko | 2009-08-27 02:25:00 -0500 (Thu, 27 Aug 2009) | 41 lines branches/zip: Replace the constant 3/8 ratio that controls the LRU_old size with the settable global variable innodb_old_blocks_pct. The minimum and maximum values are 5 and 95 per cent, respectively. The default is 100*3/8, in line with the old behavior. ut_time_ms(): New utility function, to return the current time in milliseconds. TODO: Is there a more efficient timestamp function, such as rdtsc divided by a power of two? buf_LRU_old_threshold_ms: New variable, corresponding to innodb_old_blocks_time. The value 0 is the default behaviour: no timeout before making blocks 'new'. bpage->accessed, bpage->LRU_position, buf_pool->ulint_clock: Remove. bpage->access_time: New field, replacing bpage->accessed. Protected by buf_pool_mutex instead of bpage->mutex. Updated when a page is created or accessed the first time in the buffer pool. buf_LRU_old_ratio, innobase_old_blocks_pct: New variables, corresponding to innodb_old_blocks_pct buf_LRU_old_ratio_update(), innobase_old_blocks_pct_update(): Update functions for buf_LRU_old_ratio, innobase_old_blocks_pct. buf_page_peek_if_too_old(): Compare ut_time_ms() to bpage->access_time if buf_LRU_old_threshold_ms && bpage->old. Else observe buf_LRU_old_ratio and bpage->freed_page_clock. buf_pool_t: Add n_pages_made_young, n_pages_not_made_young, n_pages_made_young_old, n_pages_not_made_young, for statistics. buf_print(): Display buf_pool->n_pages_made_young, buf_pool->n_pages_not_made_young. This function is only for crash diagnostics. buf_print_io(): Display buf_pool->LRU_old_len and quantities derived from buf_pool->n_pages_made_young, buf_pool->n_pages_not_made_young. This function is invoked by SHOW ENGINE INNODB STATUS. rb://129 approved by Heikki Tuuri. This addresses Bug #45015. r5704 | marko | 2009-08-27 03:31:17 -0500 (Thu, 27 Aug 2009) | 32 lines branches/zip: Fix a critical bug in fast index creation that could corrupt the created indexes. row_merge(): Make "half" an in/out parameter. Determine the offset of half the output file. Copy the last blocks record-by-record instead of block-by-block, so that the records can be counted. Check that the input and output have matching n_rec. row_merge_sort(): Do not assume that two blocks of size N are merged into a block of size 2*N. The output block can be shorter than the input if the last page of each input block is almost empty. Use an accurate termination condition, based on the "half" computed by row_merge(). row_merge_read(), row_merge_write(), row_merge_blocks(): Add debug output. merge_file_t, row_merge_file_create(): Add n_rec, the number of records in the merge file. row_merge_read_clustered_index(): Update n_rec. row_merge_blocks(): Update and check n_rec. row_merge_blocks_copy(): New function, for copying the last blocks in row_merge(). Update and check n_rec. This bug was discovered with a user-supplied test case that creates an index where the initial temporary file is 249 one-megabyte blocks and the merged files become smaller. In the test, possible merge record sizes are 10, 18, and 26 bytes. rb://150 approved by Sunny Bains. This addresses Issue #320. r5705 | marko | 2009-08-27 06:56:24 -0500 (Thu, 27 Aug 2009) | 11 lines branches/zip: dict_index_find_cols(): On column name lookup failure, return DB_CORRUPTION (HA_ERR_CRASHED) instead of abnormally terminating the server. Also, disable the previously added diagnostic output to the error log, because mysql-test-run does not like extra output in the error log.
