      "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
      
      
      libmysql/Makefile.shared:
        When we "make clean" in libmysql/ we remove the symlinks there, so we
        need to mark that they have to be recreated later: this is done by removing
        ../linked_libmysql_sources. If we don't do this, 'make' will fail after 'cd libmysql;make clean'.
        This Makefile.shared is used by libmysql_r too.
        No reason to remove linked_client_sources as we don't remove the links in client/.
      mysql-test/r/rpl_deadlock.result:
        result fix
      mysql-test/t/rpl_deadlock.test:
        small test addition
      sql/mysqld.cc:
        if active_mi could not be alloced, die. New SHOW STATUS LIKE "slave_retried_transactions".
      sql/slave.cc:
        If slave retries automatically a transaction, no message on error log
        (too common situation); sleep 0 secs at first retry, then 1, 2, 3, 4,
        5, 5, 5... Sleeping 0 is to get the least possible late, as deadlocks
        are usually resolved at first try. New global counter rli->retried_trans
        (for SHOW STATUS: total number of times the slave had to retry
        any transaction). safe_sleep() is thread-safe, sleep() was not.
        I change the rli->trans_retries counter to go from 0 to max instead
        of the other way (better for new sleep()).
      sql/slave.h:
        new global counter rli->retried_trans
      sql/sql_show.cc:
        SHOW STATUS LIKE "slave_retried_transactions"; needs replication mutexes.
        Can't be a simple SHOW_LONG, because active_mi is unset (not alloced yet)
        when the static global status_vars is created (active_mi is set
        in init_slave()).
      sql/structs.h:
        new SHOW_SLAVE_RETRIED_TRANS

      A change of behaviour of Seconds_Behind_Master from SHOW SLAVE STATUS. It's going into 4.1 · b3d56a7d
      unknown authored
      because old behaviour was somewhat nonsensical (kind of bug). Changes are that if repl threads are
      down or disconnected the column will be NULL, and if master is idle the column will not grow indefinitely anymore.
      
      
      sql/slave.cc:
        mi->slave_running and rli->slave_running now uints (was needed only for mi but because of start_slave_thread() usage,
        had to change both).
        So mi->slave_running can now take 3 values: not running, running & not connected, running and connected.
        The last value serves for calculation of Seconds_Behind_Master in SHOW SLAVE STATUS.
        Changing this column's behaviour: if SQL or I/O thread is not running, or if I/O thread is not connected
        (for example if it is reconnecting), it's NULL (to mean "unknown"). And if master is idle, the column will
        not grow indefinitely like it used to (that was meaningless); this is fixed by forcing a value of 0
        when the slave SQL thread has hit EOF of relay log (which has only a limited number of caveats explained
        in comments in code).
      sql/slave.h:
        slave_running used to be bool but we need to distinguish, for the I/O slave thread, between 
        "running & connected" and "running & not connected" ("running" means the thread exists).
      sql/sql_repl.cc:
        we don't need anymore to set rli->last_master_timestamp to 0 (we used that to make Seconds_Behind_Master
        be NULL) in RESET SLAVE and CHANGE MASTER, as these commands imply that slave threads are not running
        and so Seconds_Behind_Master is already NULL because of that.

      1 if the return type is int or int_fast8_t.  The test case that showed
      this problem is rpl000001 and the tested version was MySQL 5.0.2.  The
      compiler with the problem is GCC 3.0.4 runing on "Linux bitch 2.4.18
      #2 Thu Apr 11 14:37:17 EDT 2002 sparc64 unknown".
      
      By changing the return type to bool the problem disappear.  (Another
      way to make the problem disappear is to simply print the returned
      value with printf("%d",?).  The printed returned value is always 0 in
      the test cases I have run.)  This is only a partial solution to the
      problem, since someone could later change the return type of the
      function back to int or some other type that does not work.

      Optimization: in the replication slave, we can avoid doing one strlen() per event's execution, · 9aca45b3
      unknown authored
      as we already have db_len in Log_event. Only if rewrite_db() changed the db we need a strlen
      (so we now do the strlen() in rewrite_db). Plus a test (we had none for --replicate-rewrite-db :( ).
      
      
      sql/log_event.cc:
        The goal is to get of rid of one strlen() per replication event in slave:
        we don't need to compute strlen(thd->db) as we already have db_len in the event;
        only case where we need to do a strlen() is if rewrite_db() changed the db.
        Note that db_len is always a meaningful value. It's 0 if event's db is 0.
      sql/slave.cc:
        rewrite_db now returns the len of the returned db.
        print_slave_db_safe() needn't call rewrite_db() as rewrite_db() is already called by caller.
      sql/slave.h:

      Avoiding a theoretically possible crash (pthread_mutex_lock(0)) which could (at least in POSIX Threads books)
      happen on SMP machines, when a thread is going to wait on a condition and it is KILLed at the
      same time.
      Cleaning code a bit by adding a test in enter_cond() that we have the mutex (was already the case in all places
      where it's called except one which is fixed here).

      sql/sql_class.cc:
        THD::awake(): before locking the mutex, let's test it's not zero;
        in theory indeed, the killer thread may see current_cond non-zero and current_mutex zero
        (order of assignments is not guaranteed by POSIX).
        A comment noting that there is still a small chance a KILL does not work and needs
        being re-issued.
      sql/sql_class.h:
        Assert in enter_cond() that we have the mutex.
        It is already the case in all places where we call enter_cond(), so better ensure it there.

      WL#1264 "Per-thread time zone support infrastructure". · 6415966e
      unknown authored
      Added basic per-thread time zone functionality (based on public
      domain elsie-code). Now user can select current time zone
      (from the list of time zones described in system tables).
      All NOW-like functions honor this time zone, values of TIMESTAMP
      type are interpreted as values in this time zone, so now
      our TIMESTAMP type behaves similar to Oracle's TIMESTAMP WITH
      LOCAL TIME ZONE (or proper PostgresSQL type).
        
      WL#1266 "CONVERT_TZ() - basic time with time zone conversion 
      function".
        
      Fixed problems described in Bug #2336 (Different number of warnings 
      when inserting bad datetime as string or as number). This required
      reworking of datetime realted warning hadling (they now generated 
      at Field object level not in conversion functions).
        
      Optimization: Now Field class descendants use table->in_use member
      instead of current_thd macro.
      
      
      include/my_global.h:
        Added macro for reading of 32-bit ints stored in network order from
        unaligned memory location.
      include/mysqld_error.h:

        for wrong or unknown time zone specification.

        Now when truncation occurs during conversion to datetime value we are producing Warnings 
        instead of Notes. Also we are giving more clear warnings about this in some cases.

        New warnings about truncation occured during conversion to datetime value added due
        their better handling.

        their better handling. Also tweaked test a bit to made it less ambigious for reader.
      mysql-test/r/system_mysql_db.result:
        Updated test result because new system tables holding time zone descriptions were 
        added.
      mysql-test/r/timezone.result:
        Updated timezone.test to use new system variable which shows system time zone.
        Added test of warning which is produced if someone tries to store non-existing (due 
        falling into spring time-gap) datetime value into TIMESTAMP field.
      mysql-test/r/type_datetime.result:
        Separated and extended test of values and warnings produced for bad values stored in 
        DATETTIME fields.
      mysql-test/r/type_time.result:
        Now we are producing more consistent warning when we are truncating datetime value while
        storing it in TIME field.
      mysql-test/r/type_timestamp.result:
        Separated and extended test of values and warnings produced for bad
        values stored in TIMESTAMP fields.
      mysql-test/t/select.test:
        Updated test to make it less ambigous for reader.
      mysql-test/t/timezone.test:
        Updated timezone.test to use new system variable which shows system time zone.
        Added test of warning which is produced if someone tries to store non-existing (due 
        falling into spring time-gap) datetime value into TIMESTAMP field.

        Separated and extended test of values and warnings produced for bad
        values stored in DATETTIME fields.

        Separated and extended test of values and warnings produced for bad
        values stored in TIMESTAMP fields.
      scripts/mysql_create_system_tables.sh:
        Added creation of tables with time zone descriptions.
        Also added descriptions of time zones used in tests.
      scripts/mysql_fix_privilege_tables.sql:
        Added mysql.time_zone* tables family.
      sql/Makefile.am:
        Added files implementing time zone support to server, also added
        rules for building of mysql_tzinfo_to_sql converter and test_time
        test.
      sql/field.cc:
        Now we are using per-thread time zone for TIMESTAMP <-> whatever conversion.
        Fixed generation of warnings for datetime types (DATETIME/TIMESTAMP/DATE/...) and
        any other Field to datetime conversion (now we are generating warnings no in lower
        level functions like in str_to_TIME() but in Field methods. This allows generate
        better and more consistent warnings and to reuse code of str_to_TIME() outside of
        server).
        
        Added 3rd parameter to set_warning() method to be able to not increment cut fields
        but still produce a warning. Also added set_datetime_warning() family of auxiliary 
        methods which allow easier generate datetime related warnings.
        Also replaced occurences of current_thd with table->in_use member, added
        asserts for catching all places there we need to set table->in_use
        accordingly. Renamed fix_datetime() function to number_to_TIME() and
        moved it to sql/time.cc there it fits better.
      sql/field.h:
        Added comment about places where we can use table->in_use member
        instead of current_thd.
        Added 3rd parameter to Field::set_warning() method and set_datetime_warning()
        family of methods.
      sql/field_conv.cc:
        Field::set_warning() method with 2 arguments was replaced with more 
        generic set_warning() method with 3 arguments.
      sql/ha_berkeley.cc:
        Now we set table->in_use for temporary tables so we have to use
        table->tmp_table for checking if table is temporary.
      sql/item.cc:
        Replaced calls to str_to_time() and str_to_TIME() funcs with their warning
        generating analogs.
      sql/item_create.cc:
        Added creation of CONVERT_TZ function as FUNC_ARG3.
      sql/item_create.h:
        Added creation of CONVERT_TZ function as FUNC_ARG3.
      sql/item_timefunc.cc:
        Added support of per-thread time zone to NOW-like and FROM_UNIXTIME,
        UNIX_TIMESTAMP functions. 
        Added support for CONVERT_TZ function.
        Removed call to str_to_timestamp function which caused non-optimal
        behavior in certain cases. Replaced calls to str_to_time() function 
        with its warning generating analog.
      sql/item_timefunc.h:
        Added support of per-thread time zone to NOW-like and
        FROM_UNIXTIME, UNIX_TIMESTAMP functions.
        Added support of CONVERT_TZ function.
      sql/lex.h:
        Added support of CONVERT_TZ function.
      sql/log.cc:
        Added support for replication of statements depending on time zone.
      sql/mysql_priv.h:
        Now including headers with per-thread time zone support functions
        and classes. Added portable replacement of time_t - my_time_t type. 
        Added time zone as one of query distinguishing parameters for
        query cache. 
        Fixed declarations of str_to_TIME, str_to_time and 
        my_system_gmt_sec (former my_gmt_sec) since now they have one more
        out parameter which informs about wrong datetime value or data 
        truncation during conversion.
        Added warning generating version of str_to_TIME() and str_to_time()
        functions.
        Thrown away str_to_datetime/timestamp functions since they are not
        needed any longer. Added number_to_TIME function.
      sql/mysqld.cc:
        Added per-thread time zone support initialization.
        Added new startup parameter --default-time-zone.
      sql/set_var.cc:

      sql/slave.cc:
        In order to support replication of statements using time zones in 4.1 we should 
        ensure that both master and slave have same default time zone.
      sql/sql_base.cc:
        Now we are setting TABLE::in_use member for all tables (which assume
        calls to Field::store or val_ methods).
      sql/sql_cache.cc:
        Added time zone as one more query distinguishing parameter
        for query cache.

        variable indicating that this query uses per thread time zone
        so if this is updating query the time zone should be logged to 
        binlog.
      sql/sql_insert.cc:
        We should set TABLE::in_use member pointing to thread which is called
        INSERT DELAYED and not to worker thread.
      sql/sql_load.cc:
        Field::set_warning() now has one more argument now.

      sql/time.cc:
        Added support for per-thread time zones for TIMESTAMP type and
        reworked generation of warnings for TIMESTAMP and DATETIME types.
        (Introduced new TIME_to_timestamp() function. Removed hours 
        normalisation from former my_gmt_sec() since it was not working 
        and not used anywhere now, but breaks parameter constness, added
        to this function generation of warning if we are falling in spring 
        time-gap. Removed str_to_timestamp and str_to_datetime functions 
        which are no longer used. Moved fix_datetime function from
        sql/field.cc to this file as number_to_TIME() function. Added
        out parameter for str_to_TIME and str_to_time functions which
        indicates if value was truncated during conversion, removed direct 
        generation of warnings from this functions.)
      sql/unireg.cc:
        Now we are setting TABLE::in_use member for all tables (which assume
          calls to Field::store or val_ methods).
      BitKeeper/etc/ignore:

      Implementation of WL#1824 "Add replication of character set variables in 4.1", · e784947a
      unknown authored
      by binlogging some SET ONE_SHOT CHARACTER_SETetc,
      which will be enough until we have it more compact and more complete in 5.0. With the present patch,
      replication will work ok between 4.1.3 master and slaves, as long as:
      - master and slave have the same GLOBAL.COLLATION_SERVER
      - COLLATION_DATABASE and CHARACTER_SET_DATABASE are not used
      - application does not use the fact that table is created with charset of the USEd db (BUG#2326).
      all of which are not too hard to fulfill. 
      ONE_SHOT is reserved for internal use of mysqlbinlog|mysql and works only for charsets,
      so we give error if used for non-charset vars.
      Fix for BUG#3875 "mysqlbinlog produces wrong ouput  if query uses
       variables containing quotes" and BUG#3943 "Queries with non-ASCII literals are not replicated
       properly after SET NAMES".
      Detecting that master and slave have different global charsets or server ids.
      
      
      mysql-test/r/rpl_server_id1.result:
        it's normal to not run as I have added a test to compare server ids of master and slave
        at startup and stop if equal (unless --replicate-same-server-id)
      mysql-test/r/rpl_user_variables.result:
        result update (as we now print charset of user var).
      mysql-test/r/user_var.result:
        result update
      mysql-test/t/rpl_server_id1.test:
        no need to select as slave is not running
      mysql-test/t/user_var.test:
        testing if the content of user vars is escaped when mysqlbinlog prints them,
        and if the name is backquoted.
      sql/lex.h:
        new keyword ONE_SHOT
      sql/log.cc:
        when writing to the binlog, before writing the actual statement, write some SET ONE_SHOT CHARACTER_SET_CLIENT etc
        for the slave to know the charset variables (which are important as they affect the inserted data).
      sql/log_event.cc:
        print charset and collation of user var in mysqlbinlog and SHOW BINLOG EVENTS.
        escape the content of the var. Backquote its name.
        Will ask Bar to check that using my_charset_bin for escaping is ok.
      sql/set_var.cc:
        understand SET CHARACTER_SET_CLIENT=10 (don't require a string, accept a number).
        Refuse changing of GLOBAL CHARACTER_SET_SERVER/COLLATION_SERVER if binlog or slave,
        as it will make the master or slave make wrong assumptions.
        A function to catch SET ONE_SHOT on non-charset variables (which is forbidden)
      sql/set_var.h:
        no_support_one_shot to know if the var supports ONE_SHOT (only charset vars do, soon timezones).
        Accept int arg in SET CHARACTER_SET_etc
      sql/slave.cc:
        when I/O slave thread starts, verify that master's and slave charsets match.
        And by the way verify that server ids are different.
        Don't fail if UNIX_TIMESTAMP() can't be done on master (very old master), that's
        not fatal.

      very minor changes: a STOP SLAVE in a replication test to get rid of a non critical message in slave.err,
      and a comment update
      
      
      mysql-test/r/rpl_server_id2.result:
        result update
      mysql-test/t/rpl_server_id2.test:
        We stop the slave before cleaning up otherwise we'll get
        'drop table t1' executed twice, so an error in the slave.err
        (not critical).
      sql/slave.cc:
        update comment about 4.1 now that 4.1 is fixed (in a few minutes, exactly)

      A new option --replicate-same-server-id to force a slave to execute queries originating from itself · 078bda30
      unknown authored
      (WL#794). This can be of interest in some recovery-from-backup scenarios, and also when you have
      two databases in one mysqld, having a certain similarity and you want one db to be updated when the other is
      (some sort of trigger).
      Plus small fix for BUG#3568 "MySQL server crashes when built --with-debug and CHANGE MASTER +MASTER_POS_WAIT"
      
      
      sql/mysqld.cc:
        new option --replicate-same-server-id
      sql/slave.cc:
        new option replicate_same_server_id, to force a slave to execute its own queries.

      Fix for BUG#3461 "multi-table DELETE replicated despite replicate-wild-ignore-table": · 25b5718e
      unknown authored
      In tables_ok(), when there is no table having "updating==TRUE" in the list,
          return that we don't replicate this statement (the slave is supposed to
          replicate *changes* only).
          In practice, the case can only happen for this statement:
          DELETE t FROM t,u WHERE ... ;
          tables_ok(t,u) will now return 0, which (check all_tables_not_ok())
          will give a chance to tables_ok(t) to run.

      Fix for BUG#3422 "In 3.23 -> 4.0 replication, slave segfault when replicating LOAD DATA INFILE": · 89fc51ad
      unknown authored
      as we transform the 3.23 Load_log_event into a 4.0 Create_file_log_event which is one
      byte longer, we need to increment event_len. The bug was that we did not increment it,
      so later in code the end 0 was not seen so there was for example a segfault in
      strlen(fname) because fname was not 0-terminated.
      Other problems remain in 3.23->4.0 replication of LOAD DATA INFILE but they are less serious:
      Exec_master_log_pos and Relay_log_space are incorrect. I'll document them.
      They are not fixable without significant code changes (if you fix those problems in 4.0,
      you get assertion failures somewhere else etc), * which are already done in 5.0.0 *.

        as we transform the 3.23 Load_log_event into a 4.0 Create_file_log_event which is one
        byte longer, we need to increment event_len.
        So we need to modify the event_len stored in the event.
        And we need to decrement event_len when we compute the offset in the master's binlog.
