Fix bug: if there was little file I/O in InnoDB, but the insert buffer was used, it could happen that 'Pending normal aio reads' was bigger than 0, but the I/O handler thread did not get waken up in 600 seconds. This resulted in a hang, and crashing of InnoDB.
Add typecasts to ulong because ulint is __int64 in Win 64-bits
Better error message to the .err log if we have to crash the server because the buffer pool is exhausted by the lock table or the adaptive hash index
Merge
trx0trx.c:
Print more info about a trx in SHOW INNODB status; try to find the bug reported by Plaxo
buf0buf.c:
Check that page log sequence numbers are not in the future
log0recv.c, log0log.c:
Fixed a bug: if you used big BLOBs, and your log files were relatively small, InnoDB could in a big BLOB operation temporarily write over the log produced AFTER the latest checkpoint. If InnoDB would crash at that moment, then the crash recovery would fail, because InnoDB would not be able to scan the log even up to the latest checkpoint. Starting from this version, InnoDB tries to ensure the latest checkpoint is young enough. If that is not possible, InnoDB prints a warning to the .err log
Merge InnoDB-4.0.14: SAVEPOINT now implemented; InnoDB now accepts also column prefix keys; crashing bug in ON UPDATE CASCADE fixed; page checksum formula fixed
When calculating the buf pool dirty pages ratio, add also free pages to the LRU list length: no need to active flushing if there are lots of free pages in the buffer pool
Search first only 10 % of the LRU list for a replaceable block before doing an LRU flush; enable again flushing of close pages also in a flush list (checkpointing) flush
trx0trx.c:
Add forgotten return value (it was not used anywhere, fortunately)
ha_innodb.h, mysql_priv.h:
Move declaration of srv_buf_pool_max_modified_pct to ha_innodb.h and enclose it to denote it is a C variable, not C++
Clean up the working of the main thread; add a tunable parameter srv_max_buf_pool_modified_pct which can be used to make the flush phase in shutdown quicker
Do not set buffer pool to zero when we start up: that takes too much time for big buffer pools; Purify users must define UNIV_SET_MEM_TO_ZERO in univ.i to eliminate spurious (?) Purify warnings
libraries always ended up in "dir..", even though they were not supposed
to be installed anyway (they are only required at link time). Fixed it by
replacing libs_LIBRARIES with noinst_LIBRARIES for all InnoDB Makefile.am
files and by removing "libsdir = " from innobase/include/Makefile.i .
Merge InnoDB-4.0.5: new isolation levels READ COMMITTED and READ UNCOMMITTED now supported, selective deadlock resolution
mysqld.cc:
Change MySQL default isolation level to REPEATABLE READ; note that InnoDB has always had that default, and BDB and MyISAM always run at SERIALIZABLE level anyway
Small improvements
row0mysql.c:
Small improvements + fix the ALTER TABLE problem by introducing a lazy drop table it can use
ha_innobase.cc:
Some fine-tuning of optimization
Fix a bug in insert buffer B-tree upper levels; probably caused the crash by B.Fitzpatrick
buf0flu.c:
Fix a bug in previous change
A small optimization for LRU flushes to avoid losing hot pages from the buffer pool
Made innodb to compile more cleanly with debugging options
enabled. Fixed a few bugs and found a few possible bugs, which
I hope Heikki will check. Comments needs to be fixed too. Some
while() functions should be changed to do ... until for documenting
purposes, because some of them must and will be processed at least
once, or a variable would be used uninitialized.
