Call filesort_free_buffers() to free memory from filesort
sql/unireg.h:
Sub select optimization
was not properly stored in the buffer.
sql/item_strfunc.cc:
Made it work on MacOS X (bigendian) where int4store is a macro that expands
the arguments several times.
It's possible this should be done differently, like not side-stepping the
String methods the way it's done here, or fixing String::c_ptr(), but this
simple fix was the quickest way.
Protocol_cursor task
net_field_length definitions trimmed with Monty's suggestions
BitKeeper/etc/ignore:
Added sql/pack.c to the ignore list
include/my_global.h:
my_ulonglong definition moved here from mysql.h
include/mysql.h:
we define my_ulonglong here only if no global.h included
include/mysql_com.h:
net_field_length_ll definition is here now

is executed, even if the transaction spans on >=2 relay logs (bug #53).
New variable relay_log_purge =0|1
New test to verify bug #53
sql/log.cc:
Now we purge a relay log only when we are sure we won't need it,
i.e. we have executed the final query (if autocommit=1) or the COMMIT.
sql/log_event.cc:
Better tracking of the relay log's name and position
lastly executed, even if we are in a transaction which spans on
2 or more relay logs.
sql/mysql_priv.h:
new option relay_log_purge (the user can now decide himself
if he wants his relay logs to be automatically purged or not,
we don't make unsafe guesses like before)
sql/mysqld.cc:
new option --innodb (replaces --skip-innodb).
Useful for the test suite : we have skip-innodb in mysql-test-run,
but we can ('-opt.info' file) choose to start the server with
InnoDB for this test only.
New option --bdb
sql/repl_failsafe.cc:

Very nasty bug.
It was caused by double free()-ing memory of join->select and
join->quick.
I was able to pinpoint it only after using Valgrind.
Plus better fix for bug with TMP_TABLE_PARAM.
Plus new constructor for SELECT_LEX.
