The two remaining callers in non-debug builds, btr_search_guess_on_hash() and btr_search_validate(), were rewritten to call buf_page_hash_get(). To implement support for a resizeable buffer pool, the function buf_block_align() had been rewritten to perform a page hash lookup in the buffer pool. The caller was also made responsible for holding the buffer pool mutex. Because the page hash lookup is expensive and it has to be done while holding the buffer pool mutex, implement buf_block_align() by pointer arithmetics again, and make btr_search_guess_on_hash() call it. Note that this will have to be adjusted if the interface to the resizeable buffer pool is actually implemented. rb://83 approved by Heikki Tuuri, to address Issue #161. As a deviation from the approved patch, this patch also makes btr_search_validate() (invoked by CHECK TABLE) check that buf_pool->page_hash is consistent with buf_block_align(). ------------------------------------------------------------------------ r4039 | vasil | 2009-01-27 08:04:17 +0200 (Tue, 27 Jan 2009) | 5 lines branches/zip: Adjust the paths in innodb_file_per_table.diff with a recent rename of the test/result files in the MySQL tree. ------------------------------------------------------------------------ r4042 | marko | 2009-01-27 10:05:24 +0200 (Tue, 27 Jan 2009) | 2 lines branches/zip: buf_LRU_invalidate_tablespace(): Fix a race condition: read zip_size while still holding block_mutex. ------------------------------------------------------------------------ r4045 | marko | 2009-01-28 00:31:17 +0200 (Wed, 28 Jan 2009) | 8 lines branches/zip: btr_search_validate(): Fix a bogus UNIV_DEBUG assertion failure that was accidentally introduced in r4036.

If these values did not actually meet the requirements, the user could not set change a variable, then set it back to the (wonky) factory default or maximum by explicitly specifying it (SET <var>=<value> vs SET <var>=DEFAULT). Now checks also apply to the server's presets. Wonky values and maxima get corrected at startup. Consequently all non-offsetted values the user sees are valid, and users can set the variable to that exact value if they so desire. ------------------------------------------------------------------------ r4060 | marko | 2009-01-29 09:39:04 +0200 (Thu, 29 Jan 2009) | 1 line branches/zip: btr0sea.c: Revert the inadvertent change made in r4056. ------------------------------------------------------------------------
