result" (and similar bug in ADDTIME/SUBTIME).

Both Item_func_add_time/Item_func_timediff::val_str() now use
calc_time_diff() function which was backported from 5.0 (and which
was was fixed to properly handle microseconds part of its second 
argument). Also now we correctly set sign of result in case when
first argument is negative and second is positive.  

provide created shared memory objects with proper
access rights to make them usable when client and server
are running under different accounts. 
Post review fixes.

  Wrong help string fix.

into mysql.com:/usr/home/bar/mysql-4.1

in some cases, because "charset(x) = 'string'" was considered
as "x is not null" due to incorrect not_null_tables().

"After Monty's review" changes to the fix for BUG#8325 "Deadlock in replication thread stops replication":
s/sleep/safe_sleep (thread safe); sleep 0/1/2/3/4/5/5/5 (get slave less late);
no message on error log (deadlock is too common sometimes), a global counter
instead (SHOW STATUS LIKE 'slave_retried_transactions').
Plus a fix for libmysql/Makefile.shared

  Fix typo.

Additional storage engine called "blackhole". Customer request, and for that matter a Zawodny request.  With this you can alter table to a type of table that would never store data. Its a /dev/null for a database.

  If MySQL wrote to its binlog, but for some reason trx->update_undo and trx->insert_undo were NULL in InnoDB, then trx->commit_lsn was garbage, and InnoDB could assert in the log flush of trx_commit_complete_for_mysql() (Bug #9277)
