      WWe now store the catalog in Query_log_event in binlog WITHOUT its end zero. · ead47f47
      gbichot@quadita2.mysql.com authored
      This saves one byte per Query_log_event on disk compared to 5.0.[0..3]. Compatibility problems with 5.0.x where x<4
      are explained in the comments in log_event.cc. Putting back s/my_open(O_TRUNC)/(my_delete+my_create) change which had
      been wiped away by somebody doing a wrong 4.1->5.0 merge (which happened just
      before 5.0.3 :( ). Applying it to new events for LOAD DATA INFILE.
      If slave fails in Execute_load_query_log_event::exec_event(),
      don't delete the file (so that it's re-usable at next START SLAVE).
      And (youpi!) fix for BUG#3247 "a partially completed LOAD DATA INFILE is not
      executed at all on the slave" (storing an Execute_load_query_log_event
      to binlog, with its error code, instead of Delete_file_log_event).

      WL#874 "Extended LOAD DATA". · f1691140
      dlenev@brandersnatch.localdomain authored
      Now one can use user variables as target for data loaded from file
      (besides table's columns). Also LOAD DATA got new SET-clause in which
      one can specify values for table columns as expressions.
      
      For example the following is possible:
      LOAD DATA INFILE 'words.dat' INTO TABLE t1 (a, @b) SET c = @b + 1;
      
      This patch also implements new way of replicating LOAD DATA.
      Now we do it similarly to other queries.
      We store LOAD DATA query in new Execute_load_query event
      (which is last in the sequence of events representing LOAD DATA).
      When we are executing this event we simply rewrite part of query which
      holds name of file (we use name of temporary file) and then execute it
      as usual query. In the beggining of this sequence we use Begin_load_query
      event which is almost identical to Append_file event

      WL#1062 "log charset info into all Query_log_event": · ed1696f6
      guilhem@mysql.com authored
      we store 7 bytes (1 + 2*3) in every Query_log_event.
      In the future if users want binlog optimized for small size and less safe,
      we could add --binlog-no-charset (and binlog-no-sql-mode etc): charset info
      is something by design optional (even if for now we don't offer possibility to disable it):
      it's not a binlog format change.
      We try to reduce the number of get_charset() calls in the slave SQL thread to a minimum
      by caching the charset read from the previous event (which will often be equal to the one of the current event).
      We don't use SET ONE_SHOT for charset-aware repl (we still do for timezones, will be fixed later).
      No more errors if one changes the global value of charset vars on master or slave
      (as we log charset info in all Query_log_event).
      Not fixing Load_log_event as it will be rewritten soon by Dmitri.
      Testing how mysqlbinlog behaves in rpl_charset.test.
      mysqlbinlog needs to know where charset file is (to be able to convert a charset number found
      in binlog (e.g. in User_var_log_event) to a charset name); mysql-test-run needs to pass
      the correct value for this option to mysqlbinlog.
      Many result udpates (adding charset info into every event shifts log_pos in SHOW BINLOG EVENTS).
      Roughly the same job is to be done for timezones :)

      This is the final commit for Worklog tasks: · df3b1a54
      guilhem@gbichot2 authored
         * A more dynamic binlog format which allows small changes (1064)
         * Log session variables in Query_log_event (1063)
      It contains a few bugfixes (which I made when running the testsuite).
      I carefully updated the results of the testsuite (i.e. I checked for every one,
      if the difference between .reject and .result could be explained).
      Apparently mysql-test-run --manager is broken in 4.1 and 5.0 currently,
      so I could neither run the few tests which require --manager, nor check
      that they pass nor modify their .result. But for builds, we don't run
      with --manager.
      Apart from --manager, the full testsuite passes, with Valgrind too (no errors).
      I'm going to push in the next minutes. Remains: update the manual.
      Note: by chance I saw that (in 4.1, in 5.0) rpl_get_lock fails when run alone;
      this is normal at it makes assumptions on thread ids. I will fix this one day
      in 4.1.
