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

9c86441ef6 ha_innobase.cc: 
Fix the crashes reported by Peter; SHOW CREATE does not call external_lock before calling ::info, and consequently the trx struct in prebuilt is obsolete; setting trx->op_info caused erratic memory corruption in mysqldump

43439d0c13 btr0cur.c, ha_innobase.cc: 
Fine-tune optimization parameters; in small tables the estimates are accurate; in big tables let us not be too optimistic about index selectivity

fef87f20af Fix in SHOW GRANTS: REFERENCE -> REFERENCES 2002-01-30 16:09:19 +02:00
heikki@donna.mysql.fi
b908f410fb ha_innobase.cc: 
Assume selectivity of any key prefix is better than 1 / 100, regardless of what the estimator returns; this balances the pessimistic assumption of the optimizer thatany secondary key access to the full row incurs a page read from disk

3fef3c7e5b mysqld.cc: 
Changed default of file_io_threads to 4 and lock_wait_timeout to 50 seconds
  Added a missing break: if not specified, innodb_fast_shutdown got the same value as ..flush_log_at_trx commit

954920c874 ha_innobase.cc:

ha_innobase.h:

0b39319672 ha_innobase.h:

6a01d8bc26 ha_innobase.cc: 
Do not automatically calculate new statistics when a temporary table is used by MySQL in a query. The fact that some ORDER BY queries were slow may have been explained by this unnecessary statistics calculation.

f7acf09d9c slave-skip-errors 
added extra/mysql_install.c - will work on it in 4.0, but it does not hurt
to have it sit in 3.23 tree for now since it will eventually be backported 
to 3.23 anyway

00774d74fc backport of shutdown fix for platforms that cannot break a syscall with a 
signal. Tested to the extent that it does not break Linux. Could not test on
Darwin because the machine was not reachable. Will push anyway - at least it
does not make things worse. Testing on Darwin is needed, however.
