From revisions r5792 to r5864 Detailed revision comments: r5792 | vasil | 2009-09-09 08:35:58 -0500 (Wed, 09 Sep 2009) | 32 lines branches/zip: Fix a bug in manipulating the variable innodb_old_blocks_pct: for any value assigned it got that value -1, except for 75. When assigned 75, it got 75. mysql> set global innodb_old_blocks_pct=15; Query OK, 0 rows affected (0.00 sec) mysql> show variables like 'innodb_old_blocks_pct'; +-----------------------+-------+ | Variable_name | Value | +-----------------------+-------+ | innodb_old_blocks_pct | 14 | +-----------------------+-------+ 1 row in set (0.00 sec) mysql> set global innodb_old_blocks_pct=75; Query OK, 0 rows affected (0.00 sec) mysql> show variables like 'innodb_old_blocks_pct'; +-----------------------+-------+ | Variable_name | Value | +-----------------------+-------+ | innodb_old_blocks_pct | 75 | +-----------------------+-------+ After the fix it gets exactly what was assigned. Approved by: Marko (via IM) r5798 | calvin | 2009-09-09 10:28:10 -0500 (Wed, 09 Sep 2009) | 5 lines branches/zip: HA_ERR_TOO_MANY_CONCURRENT_TRXS is added in 5.1.38. But the plugin should still work with previous versions of MySQL. r5804 | marko | 2009-09-10 00:29:31 -0500 (Thu, 10 Sep 2009) | 1 line branches/zip: trx_cleanup_at_db_startup(): Fix a typo in comment. r5822 | marko | 2009-09-10 05:10:20 -0500 (Thu, 10 Sep 2009) | 1 line branches/zip: buf_page_release(): De-stutter the function comment. r5825 | marko | 2009-09-10 05:47:09 -0500 (Thu, 10 Sep 2009) | 20 lines branches/zip: Reduce mutex contention that was introduced when addressing Bug #45015 (Issue #316), in r5703. buf_page_set_accessed_make_young(): New auxiliary function, called by buf_page_get_zip(), buf_page_get_gen(), buf_page_optimistic_get_func(). Call ut_time_ms() outside of buf_pool_mutex. Use cached access_time. buf_page_set_accessed(): Add the parameter time_ms, so that ut_time_ms() need not be called while holding buf_pool_mutex. buf_page_optimistic_get_func(), buf_page_get_known_nowait(): Read buf_page_t::access_time without holding buf_pool_mutex. This should be OK, because the field is only used for heuristic purposes. buf_page_peek_if_too_old(): If buf_pool->freed_page_clock == 0, return FALSE, so that we will not waste time moving blocks in the LRU list in the warm-up phase or when the workload fits in the buffer pool. rb://156 approved by Sunny Bains r5826 | marko | 2009-09-10 06:29:46 -0500 (Thu, 10 Sep 2009) | 12 lines branches/zip: Roll back recovered dictionary transactions before dropping incomplete indexes (Issue #337). trx_rollback_or_clean_recovered(ibool all): New function, split from trx_rollback_or_clean_all_recovered(). all==FALSE will only roll back dictionary transactions. recv_recovery_from_checkpoint_finish(): Call trx_rollback_or_clean_recovered(FALSE) before row_merge_drop_temp_indexes(). rb://158 approved by Sunny Bains r5858 | vasil | 2009-09-11 12:46:47 -0500 (Fri, 11 Sep 2009) | 4 lines branches/zip: Fix the indentation of the closing bracket. r5863 | vasil | 2009-09-12 02:07:08 -0500 (Sat, 12 Sep 2009) | 10 lines branches/zip: Check that pthread_t can indeed be passed to Solaris atomic functions, instead of assuming that it can be passed if 0 can be assigned to it. It could be that: * 0 can be assigned, but pthread_t cannot be passed and * 0 cannot be assigned but pthread_t can be passed Better to check what we are interested in, not something else and make assumptions. r5864 | vasil | 2009-09-12 02:22:55 -0500 (Sat, 12 Sep 2009) | 4 lines branches/zip: Include string.h which is needed for memset(). |
