They are only assigned to by buf_block_set_file_page(). Thus, it suffices for buf_flush_batch() to hold just buf_pool_mutex when checking these fields. buf_flush_try_page(): Rename "locked" to "is_s_latched", per Heikki's request. buf_flush_batch(): Move the common statement mutex_exit(block_mutex) from all if-else if-else branches before the if block. Remove the redundant test (buf_pool->init_flush[flush_type] == FALSE) that was apparently copied from buf_flush_write_complete(). buf_flush_write_block_low(): Note why it is safe not to hold buf_pool_mutex or block_mutex.

The flush_type comes from buf_flush_batch(), which already asserts this. The assertion holds for all calls in the source code. buf_flush_try_page(): Remove the dead case BUF_FLUSH_SINGLE_PAGE of switch (flush_type). ------------------------------------------------------------------------ r3879 | marko | 2009-01-12 12:46:44 +0200 (Mon, 12 Jan 2009) | 14 lines branches/zip: Simplify the flushing of dirty pages from the buffer pool. buf_flush_try_page(): Rename to buf_flush_page(), and change the return type to void. Replace the parameters space, offset with bpage, and remove the second page hash lookup. Note and assert that both buf_pool_mutex and block_mutex must now be held upon entering the function. They will still be released by this function. buf_flush_try_neighbors(): Replace buf_flush_try_page() with buf_flush_page(). Make the logic easier to follow by not negating the precondition of buf_flush_page(). rb://73 approved by Sunny Bains.

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. ------------------------------------------------------------------------
