irana 7f74120473 branches/innodb+ Merge r6915:6992 from branches/innodb+multipbp (i.e.: all the changes made since it's creation) This also reverts r6930 to branches/innodb+ because a different solution for that issue is already present in innodb+multibp which is being merged. After this commit branches/innodb+multibp should be discarded and this branch should become our main development tree. ------------------------------------------------------------------------ r6915 \| sbains \| 2010-03-31 07:33:43 +0300 (Wed, 31 Mar 2010) \| 1 line Changed paths: A /branches/innodb+multibp (from /branches/innodb+:6914) Creating a branch for the multiple buffer pool ------------------------------------------------------------------------ r6916 \| sbains \| 2010-03-31 08:21:00 +0300 (Wed, 31 Mar 2010) \| 3 lines Changed paths: M /branches/innodb+multibp/CMakeLists.txt M /branches/innodb+multibp/btr/btr0btr.c M /branches/innodb+multibp/btr/btr0cur.c M /branches/innodb+multibp/btr/btr0sea.c M /branches/innodb+multibp/buf/buf0buddy.c M /branches/innodb+multibp/buf/buf0buf.c M /branches/innodb+multibp/buf/buf0flu.c M /branches/innodb+multibp/buf/buf0lru.c M /branches/innodb+multibp/buf/buf0rea.c M /branches/innodb+multibp/handler/ha_innodb.cc M /branches/innodb+multibp/handler/i_s.cc M /branches/innodb+multibp/ibuf/ibuf0ibuf.c M /branches/innodb+multibp/include/buf0buddy.h M /branches/innodb+multibp/include/buf0buddy.ic M /branches/innodb+multibp/include/buf0buf.h M /branches/innodb+multibp/include/buf0buf.ic M /branches/innodb+multibp/include/buf0flu.h M /branches/innodb+multibp/include/buf0flu.ic M /branches/innodb+multibp/include/buf0lru.h M /branches/innodb+multibp/include/buf0rea.h M /branches/innodb+multibp/include/buf0types.h M /branches/innodb+multibp/include/ibuf0ibuf.ic M /branches/innodb+multibp/include/srv0srv.h M /branches/innodb+multibp/include/univ.i M /branches/innodb+multibp/log/log0log.c M /branches/innodb+multibp/log/log0recv.c M /branches/innodb+multibp/mem/mem0mem.c M /branches/innodb+multibp/page/page0zip.c M /branches/innodb+multibp/srv/srv0srv.c M /branches/innodb+multibp/srv/srv0start.c M /branches/innodb+multibp/trx/trx0trx.c M /branches/innodb+multibp/trx/trx0undo.c branches/innodb+multibp: Unable to crash it with UNIV_DEBUG and UNIV_SYNC_DEBUG with both ibtests and Sysbench.

Up to say buffer pool 3 the oldest_lsn was 0. Now, we will end up returning the lsn at buffer pool 4 as the oldest LSN. We prevent this by acquiring the flush order mutex. One other future option is to calculate the min_lsn when flushing pages from the list and maintaining a running total using atomics. That way we can get rid of this function altogether. The atomics will only really be required when we do parallel flushing. ------------------------------------------------------------------------ r6992 \| sbains \| 2010-04-14 02:45:59 +0300 (Wed, 14 Apr 2010) \| 2 lines Changed paths: M /branches/innodb+multibp/include/ut0rbt.h M /branches/innodb+multibp/ut/ut0rbt.c branches/innodb+multibp: Fix copyright of the rbt code. ------------------------------------------------------------------------		16 years ago
