first pull, merge,test, and get it to work. The main change is the new replication code - now we have two slave threads SQL thread and I/O thread. I have also re-written a lot of the code to prepare for multi-master implementation. I also documented IO_CACHE quite extensively and to some extend, THD class. Makefile.am: moved tags target script into a separate file include/my_sys.h: fixes in IO_CACHE for SEQ_READ_APPEND + some documentation libmysqld/lib_sql.cc: updated replication locks, but now I see I did it wrong and it won't compile. Will fix before the push. mysql-test/r/rpl000014.result: test result update mysql-test/r/rpl000015.result: test result update mysql-test/r/rpl000016.result: test result update mysql-test/r/rpl_log.result: test result update mysql-test/t/rpl000016-slave.sh: remove relay logs mysql-test/t/rpl000017-slave.sh: remove relay logs mysql-test/t/rpl_log.test: updated test mysys/mf_iocache.c: IO_CACHE updates to make replication work mysys/mf_iocache2.c: IO_CACHE update to make replication work mysys/thr_mutex.c: cosmetic change sql/item_func.cc: new replication code sql/lex.h: new replication sql/log.cc: new replication sql/log_event.cc: new replication sql/log_event.h: new replication sql/mini_client.cc: new replication sql/mini_client.h: new replication sql/mysql_priv.h: new replication sql/mysqld.cc: new replication sql/repl_failsafe.cc: new replication sql/slave.cc: new replication sql/slave.h: new replication sql/sql_class.cc: new replication sql/sql_class.h: new replication sql/sql_lex.h: new replication sql/sql_parse.cc: new replication sql/sql_repl.cc: new replication sql/sql_repl.h: new replication sql/sql_show.cc: new replication sql/sql_yacc.yy: new replication sql/stacktrace.c: more robust stack tracing sql/structs.h: new replication code BitKeeper/etc/ignore: Added mysql-test/r/rpl000002.eval mysql-test/r/rpl000014.eval mysql-test/r/rpl000015.eval mysql-test/r/rpl000016.eval mysql-test/r/slave-running.eval mysql-test/r/slave-stopped.eval to the ignore list
