378894b000 This will be pushed only after I fix the testsuite.
This is the main commit for Worklog tasks:
 * A more dynamic binlog format which allows small changes (1064)
 * Log session variables in Query_log_event (1063)
Below 5.0 means 5.0.0.
MySQL 5.0 is able to replicate FOREIGN_KEY_CHECKS, UNIQUE_KEY_CHECKS (for speed),
SQL_AUTO_IS_NULL, SQL_MODE. Not charsets (WL#1062), not some vars (I can only think
of SQL_SELECT_LIMIT, which deserves a special treatment). Note that this
works for queries, except LOAD DATA INFILE (for this it would have to wait
for Dmitri's push of WL#874, which in turns waits for the present push, so...
the deadlock must be broken!). Note that when Dmitri pushes WL#874 in 5.0.1,
5.0.0 won't be able to replicate a LOAD DATA INFILE from 5.0.1.
Apart from that, the new binlog format is designed so that it can tolerate
a little variation in the events (so that a 5.0.0 slave could replicate a
5.0.1 master, except for LOAD DATA INFILE unfortunately); that is, when I
later add replication of charsets it should break nothing. And when I later
add a UID to every event, it should break nothing.
The main change brought by this patch is a new type of event, Format_description_log_event,
which describes some lengthes in other event types. This event is needed for
the master/slave/mysqlbinlog to understand a 5.0 log. Thanks to this event,
we can later add more bytes to the header of every event without breaking compatibility.
Inside Query_log_event, we have some additional dynamic format, as every Query_log_event
can have a different number of status variables, stored as pairs (code, value); that's
how SQL_MODE and session variables and catalog are stored. Like this, we can later
add count of affected rows, charsets... and we can have options --don't-log-count-affected-rows
if we want.
MySQL 5.0 is able to run on 4.x relay logs, 4.x binlogs.
Upgrading a 4.x master to 5.0 is ok (no need to delete binlogs),
upgrading a 4.x slave to 5.0 is ok (no need to delete relay logs);
so both can be "hot" upgrades.
Upgrading a 3.23 master to 5.0 requires as much as upgrading it to 4.0.
3.23 and 4.x can't be slaves of 5.0.
So downgrading from 5.0 to 4.x may be complicated.
Log_event::log_pos is now the position of the end of the event, which is
more useful than the position of the beginning. We take care about compatibility
with <5.0 (in which log_pos is the beginning).
I added a short test for replication of SQL_MODE and some other variables.
TODO:
- after committing this, merge the latest 5.0 into it
- fix all tests
- update the manual with upgrade notes.


client/Makefile.am:
  mysqlbinlog.cc depends slightly on sql/mysql_priv.h
client/mysqlbinlog.cc:
  Make mysqlbinlog able to read the new binlog format,
  by seeking to the start and reading the first few events, to
  detect the format of the binlog.
include/my_sys.h:
  a correct tell() for SEQ_READ_APPEND caches.
mysys/mf_iocache2.c:
  a correct tell() for SEQ_READ_APPEND caches
  (my_b_tell() is not working for such caches).
sql/ha_innodb.cc:
  we are getting rid of event lengthes here and there, which is good.
sql/log.cc:
  Start events will have created==0 if generated by rotation (like in 3.23).
  In 5.0 we always write a Format_description_log_event at the beginning of
  every master's binary log and of every slave's relay log.
  We also add Rotate and Stop to relay logs (like there already was in
  master's binary logs).
  When we rotate a relay log, we write the previous relay log's Start event
  (the one which was sent from the master) to the beginning of the new log,
  so that we don't need the previous relay log to understand the new one;
  that's the purpose of MYSQL_LOG::description_event_for_queue.
  Removed logging of SET FOREIGN_KEY_CHECKS, because we handle it as flags
  in the Query event now.
sql/log_event.cc:
  New event type: Format_description_log_event, to describe the log's format.
  read_log_event() needs to be passed this event to be able to read 5.0 events.
  Query_log_event has new members flags2 and sql_mode for replication of session
  variables (except charsets which are WL#1062) and SQL_MODE.
  flags2 is in fact a kind of copy of thd->options (&'d with a mask).
  Now with this replication of FOREIGN_KEY_CHECKS, SQL_AUTO_IS_NULL, UNIQUE_CHECKS
  and SQL_MODE work; with mysqlbinlog too.
sql/log_event.h:
  Binlog version is changed to 4.
  New classes (details in sql/log_event.cc).
  Removing some useless #defines.
sql/mysql_priv.h:
  Definition of SELECT_DISTINCT and others must be visible in client/mysqlbinlog.cc,
  so adding #ifdefs.
sql/mysqld.cc:
  update for prototype change
sql/slave.cc:
  When the slave opens a relay log, it reads the first few events to know the format.
  When slave I/O thread receives a Rotate from the master, it rotates its relay log
  (to avoid mixed format in the relay log).
sql/slave.h:
  in the slave we avoid lengthes and rely on absolute positions instead;
  hence the introduction of future_group_master_log_pos and future_event_relay_log_pos
  (explained in code).
sql/sql_class.cc:
  catalog in THD
sql/sql_class.h:
  catalog, and new members in MYSQL_LOG
sql/sql_repl.cc:
  When the master starts sending binlog to slave, it must
  first read the first few events to detect the binlog's format.
  Same for SHOW BINLOG EVENTS.

66927c51fa - Fix for BUG#1858 "SQL-Thread stops working when using optimize table":
we change THD::system_thread from a 'bool' to a bitmap to be able to
distinguish between delayed-insert threads and slave threads.
- Fix for BUG#1701 "Update from multiple tables" (one line in sql_parse.cc,
plus a new test rpl_multi_update.test). That's just adding an initialization.


sql/repl_failsafe.cc:
  comment to warn about this unused code
sql/slave.cc:
  Now thd->system_thread is a bitmap, not a bool.
sql/sql_class.h:
  'bool' for THD::system_thread is not accurate enough; sometimes we need
  to distinguish between delayed-insert threads and slave threads;
  so changing THD::system_thread to a bitmap (uint).
sql/sql_insert.cc:
  thd.system_thread is now a bitmap
sql/sql_parse.cc:
  We need to initialize thd->lex.select_lex.options in mysql_init_query();
  it's already initialized in dispatch_command() but replication calls
  mysql_parse() directly, thus bypassing dispatch_command().
  Not initing it here leads to a query influencing the next query,
  in the slave SQL thread.
  The initialization in dispatch_command() must be kept as this
  command uses the variable in tests, even when the command was not a
  query (i.e. when mysql_init_query() was not called).

8479e5a379 Fix for BUG#2011 "rare race condition producing "binlog has bad magic number" error in slave".
The problem was that when the slave SQL thread reads a hot relay log (hot = the one being written to by the
slave I/O thread), it must have the LOCK_log. It already took it for read_log_event(), but needs
it also for check_binlog_magic().
This should fix all recently reported failures of the rpl_max_relay_size test in 4.1 and 5.0
(though the bug exists since 4.0, it showed up first in 5.0).

7ec796f31a In the slave I/O thread (in master.info), it seems less worse to flush
the relay log before flushing master.info.
Doing 'before' leads to duplicate event, doing after leads to missing event.
Both can be as destructive, but 'duplicate' enables us to later add detection
code to catch it. Whereas 'missing' can't be caught (it can't, because
the I/O thread can produce legal position jumps, for example if it has
ignored an event coming from this slave (rememember that starting from 4.1.1,
the I/O thread filters the server id).

bd6a70019e Replication:
Now the I/O thread (in flush_master_info()) flushes the relay log to disk
after reading every event. Slower but provides additionnal safety in case
of brutal crash.
I had to make the flush optional (i.e. add a if(some_bool_argument) in the function)
because sometimes flush_master_info() is called when there is no usable
relay log (the relay log's IO_CACHE is not initialized so can't be flushed).

(in old 4.0 you could make "SHOW STATUS LIKE 'slave_open_temp_tables'" grow
indefinitely by doing RESET SLAVE and replicating always the same CREATE

It's critical to reset save_temporary_tables to 0 (otherwise you may later
read memory which has been freed) so this changeset should go into 4.1.

indefinitely by doing RESET SLAVE and replicating always the same CREATE
TEMPORARY TABLE).
It's critical to reset save_temporary_tables to 0 (otherwise you may later
read memory which has been freed) so this changeset should go into 4.1.

b920ab261e 4 small items in this:
- when we don't have in_addr_t, use uint32.
- a forgotten initialization of slave_proxy_id in sql/log_event.cc (was not really "forgot", was
"we needn't init it there", but there was one case where we needed...).
- made slave_proxy_id always meaningful in THD and Log_event, so we can
rely more on it (no need to test if it's meaningful). THD::slave_proxy_id
is equal to THD::thread_id except for the slave SQL thread.
- clean up the slave's temporary table (i.e. free their memory) when slave
server shuts down.


extra/resolveip.c:
  removed #define as it is simpler to put it in my_net.h
  (because we need the #define elsewhere)
include/my_net.h:
  When in_addr_t is not defined, use uint32.
libmysql/libmysql.c:
  using in_addr_t is more generic.
libmysql/manager.c:
  using in_addr_t is more generic.
mysql-test/t/rpl_chain_temp_table.test:
  comments
sql/log_event.cc:
  * Had forgot to initialize slave_proxy_id in the event constructor (char* buf...).
  Initializing is in fact only needed for Create_file_log_event, because
  it uses slave_proxy_id even if it does not write an event to the binlog
  (it uses slave_proxy_id to write it to SQL-LOAD.info).
  * When we write events we now always write slave_proxy_id, which is now always
  meaningful (as thd->slave_proxy_id is now always meaningful, see change in
  sql_class.cc).
sql/mini_client.cc:
  in_addr_t is more generic.
sql/slave.cc:
  A RELAY_LOG_INFO method to free the slave's temporary tables from memory
  at slave's server shutdown.
  It is called by end_slave(), which is called by close_connections(),
  which is called when the server terminates
  (close_connections() is just before clean_up(); putting the call in 
  clean_up() was buggy, as active_mi is already deleted by close_connections().
sql/slave.h:
  new method
sql/sql_class.cc:
  By default we set THD::slave_proxy_id to THD::thread_id,
  so THD::slave_proxy_id is always meaningful (not 0).
  It's always the same as the thread id except for the slave
  SQL thread.

03dbf8ccbb Fix for BUG#1686
"If 2 master threads with same-name temp table, slave makes bad binlog"
and (two birds with one stone) for
BUG#1240 "slave of slave breaks when STOP SLAVE was issud on parent slave
and temp tables".

Here is the design change:
in a slave running with --log-slave-updates, events are now logged with the
thread id they had on the master. So no more id conflicts between master threads,
but introduces id conflicts between one master thread and one normal 
client thread connected to the slave. This is solved by storing the server id
in the temp table's name.

New test which requires mysql-test-run to be run with --manager,
otherwise it will be skipped.

Undoing a Monty's change (hum, a chill runs down my spine ;) which was
"Cleanup temporary tables when slave ends" in ChangeSet 1.1572.1.1.


mysql-test/mysql-test-run.sh:
  One new test which needs more than one slave so must be hardcoded in mysql-test-run.sh.
sql/log_event.cc:
  The event needs to carry a slave_proxy_id (which is set at event's creation
  and used at event's logging).
  This is used for events created by ::exec_event() in the slave SQL thread:
  now we want to log these events with the thread id they had on the master.
  This is so that several same-name temp tables simultaneously created on
  the master end up with not the same thread id in the slave's binlog.
sql/log_event.h:
  Query and Load need to carry a slave_proxy_id, like they carried a thread_id
  (to replicate temp tables well).
sql/slave.cc:
  Do not free temp tables in the slave SQL thread. Or they will be lost when
  one does STOP SLAVE / START SLAVE.
  We even save them in rli->save_temporary_tables and set thd->temporary_tables=0
  to prevent them to be freed.
sql/sql_base.cc:
  Put the server id in the table cache key name for temp tables
  (we already put the slave_proxy_id, but we also need the server id
  in case normal clients (not slave threads) are using temp tables
  on the slave).
sql/unireg.h:
  4 more bytes, to store the server id.
