If a temporary error occured inside a group on an event that was not the first
event of the group, the slave could get stuck because the retry counter is reset
whenever an event was executed successfully.

This patch only reset the retry counter when an entire group has been successfully
executed, or failed with a non-transient error.


sql/slave.cc:
  Adding debug printouts to every place where Relay_log_info::trans_retries
  is changed and to has_temporary_error() to print the error when returning.
  
  Adding debug variable all_errors_are_temporary_errors to make all errors
  for slave thread temporary errors.

When replicating an update pair (before image, after image) under row-based
replication, and the before image is not found on the slave, the after image
was not discared, and was hence read as a before image for the next row.
Eventually, this lead to an after image being read outside the block of rows
in the event, causing an assertion to fire.

This patch fixes this by reading the after image in the event that the row
was not found on the slave, adds some extra debug assertion to catch future
errors earlier, and also adds a few non-debug checks to prevent reading
outside the block of the event.

  Adding test to try to use row-based replication to replicate an
  update of a row that doesn't exist on the slave. We should get
  an apropriate error and the slave should stop.
sql/log_event.cc:
  Adding debug printouts. Adding code to Update_rows_log_event::do_exec_row()
  so that the after image is read (and ignored) in the event of an error in
  finding the row. This is necessary so that the second pair of images is
  read correctly for the next update pair.
  
  Changing logic for ignoring errors to not include update events, since
  a "key not found" error or a "record changed" error is not idempotent
  for updates, just for deletes and inserts.
sql/log_event.h:
  Adding debug assertions to check that row reading is within the events block of rows.

is possible):

When skipping the beginning of a transaction starting with BEGIN, the OPTION_BEGIN
flag was not set correctly, which caused the slave to not recognize that it was
inside a group. This patch sets the OPTION_BEGIN flag for BEGIN, COMMIT, ROLLBACK,
and XID events. It also adds checks if inside a group before decreasing the
slave skip counter to zero.

Begin_query_log_event was not marked that it could not end a group, which is now
corrected.

sql/log_event.cc:

  Adding helping member function Log_event::continue_group() denoting
  that this event cannot end a group, and if the skip counter indicates
  that the group ends after this event, it should not decrease the skip
  counter.
  
  Query_log_event will change the OPTION_BEGIN flag for BEGIN, COMMIT, and
  ROLLBACK, even when skipping because of a positive skip count, and
  Xid_log_event will also affect the OPTION_BEGIN flag, even when being
  skipped.
  
  Begin_load_query_log_event cannot end a group, so it is marked to
  continue the group.
sql/log_event.h:
  Adding helper function Log_event::continue_group().
sql/rpl_rli.h:

similar to bug_27716, but it was stressed on in the synopsis on that there is another
side of the artifact affecting behaviour in transaction.

Fixed with deploying multi_delete::send_error() - otherwise never called - and refining its logic
to perform binlogging job if needed.

The changeset includes the following side effects:
- added tests to check bug_23333's scenarios on the mixture of tables for multi_update;
- fixes bug@30763 with two-liner patch and a test coinciding to one added for bug_23333.

sql/sql_delete.cc:
  expanding multi_delete::send_error to 
  1. early return if error_handled == t
  2. binlogging locally if there was a non-trans table modified side effect
sql/sql_parse.cc:
  adding multi_update::send_error which can perform binlogging and rollback job in needed
sql/sql_update.cc:
  issues relating to
   
  1. bug_27716 with zeroing of `updated' to serve as the flag of early return from send_error().
     The flag is changed to be a new member error_handled; also moved outside binlogging branch.
     The reason for this change is that bug_23333 fixes were pushed after the bug_27716's and they
     left this flaw (also no test coverage).
  2. bug_30763 with assertion on trans_safe. I decide to make 2 liner fix for that bug here instead of to remove
     those two assertions. This new bug test case is the same as for multi-update on the mixure of tables.
     The rational for this fix:
     presumption for mutli_update::trans_safe to be set to zero at
     multi_update::multi_update or multi_update::initialize_tables() is incorrect.
  
     trans_safe := false should happen only when a non-transactional table gets modified. 
     Therefore, at initialization the member must be be set to true.

Post-merge fixes. Setting write bit before calling Field::store() since the function asserts that
the write bit has been set.

Refactoring code to add parameter to pack() and unpack() functions with
purpose of indicating if data should be packed in little-endian or
native order. Using new functions to always pack data for binary log
in little-endian order. The purpose of this refactoring is to allow
proper implementation of endian-agnostic pack() and unpack() functions.

Eliminating several versions of virtual pack() and unpack() functions
in favor for one single virtual function which is overridden in
subclasses.

Implementing pack() and unpack() functions for some field types that
packed data in native format regardless of the value of the
st_table_share::db_low_byte_first flag.

The field types that were packed in native format regardless are:
Field_real, Field_decimal, Field_tiny, Field_short, Field_medium,
Field_long, Field_longlong, and Field_blob.

Before the patch, row-based logging wrote the rows incorrectly on
big-endian machines where the storage engine defined its own
low_byte_first() to be FALSE on big-endian machines (the default
is TRUE), while little-endian machines wrote the fields in correct
order. The only known storage engine that does this is NDB. In effect,
this means that row-based replication from or to a big-endian
machine where the table was using NDB as storage engine failed if the
other engine was either non-NDB or on a little-endian machine.

With this patch, row-based logging is now always done in little-endian
order, while ORDER BY uses the native order if the storage engine
defines low_byte_first() to return FALSE for big-endian machines.

In addition, the max_data_length() function available in Field_blob
was generalized to the entire Field hierarchy to give the maximum
number of bytes that Field::pack() will write.

sql/field.cc:
  Eliminating all two-argument pack() and unpack() functions and moving

  replication to write the fields in a storage engine- and endian-agnostic
  format.
  
  Packing integral and floating-point numbers in little-endian format

  Using pad_char for the field instead of spaces (0x20) when unpacking.

Problem: rpl_stm_mystery22 is unstable.

Reason: At one place, the test case *should* wait until the SQL thread on the
slave receives an error, but instead it waits until the SQL thread stops. The
SQL thread may stop before the error flag is set, so that when the test case
continues to execute, the error flag is not set.

Fix: Introduce the subroutine mysql-test/include/wait_for_slave_sql_error.inc,
which waits until there is an error in the sql thread of the slave.

Re-commit: fixed one logical error and two smaller things noted by Mats.


mysql-test/suite/rpl/t/rpl_stm_mystery22.test:
  Use the new wait_for_slave_sql_error.inc instead of wait_for_slave_to_stop.
  There may be a delay from when the slave stops to when Last_SQL_Errno is set,
  so it is not safe to merely wait until the slave stops.
mysql-test/include/wait_for_slave_sql_error.inc:

Performance improvements made.
ExtractValue for large XML values is now much faster
(about 2000 times faster of 1Mb-long XML values).


sql/item_xmlfunc.cc:
  Performance improvement for huge XML values:
  1. Avoid reallocs - reserve extra memory:
  using String::reserve() + String::q_append()
  instead of String::append()
  2. Parent is now not searched through the all previous
  nodes in backward direction. Instead, we do the following:
  - we introduce data->parent - a new member in MY_XML_USER_DATA
  - when entering a new tag/attribute node, we remember offset
    of the current node in data->parent
  - when leaving a tag/attribute node, we change data->parent
    to offset of the parent of the current node.

Report claims that Seconds_behind_master behaves unexpectedly. 

Code analysis shows that there is an evident flaw in that treating of FormatDescription event is wrong
so  that after FLUSH LOGS on slave the Seconds_behind_master's calculation slips and incorrect
value can be reported to SHOW SLAVE STATUS. 
Even worse is that the gap between the correct and incorrect deltas grows with time.

Fixed with prohibiting changes to rpl->last_master_timestamp by artifical events (any kind of).
suggestion as comments is added how to fight with lack of info on the slave side by means of
new heartbeat feature coming.

The test can not be done ealily fully determistic.


sql/log_event.cc:
  changing timestamp is affirmed only by non-artificial events. Artifical FD won't change it anymore.

mysql-test/suite/manual/t/rpl_replication_delay.test:
  specic test for bug#29309. It's hard to make it reliable as it deals with timestamps.
  (a way to automate the test like this is to have I_S table for show slave status' fields)
  
  A possible way to check results is to run
  grep -i 'show\|seconds' < suite/manual/r/rpl_replication_delay.reject and to get the lines like these:
  
  show slave status /* Second_behind reports 0 */;;
  Seconds_Behind_Master   0
  show slave status /* bug emulated: reports slave threads starting time about 3*3 not 3 secs */;;
  Seconds_Behind_Master   9
  show slave status /* reports the correct diff with master query time about 3+3 secs */;;
  Seconds_Behind_Master   6
  
  Due to time discreteness of time the reported numbers may slightly vary. That's why the test is not reliable.

  Initialize all members in constructor for more safe future code.
sql/sql_repl.cc:
  Swap order so that linfo is first initialized, then assigned, instead of the
  other way around.
  Put a lock around the assignment. We use LOCK_thread_count since log_in_use
  uses it: log_in_use may be running concurrently, called from
  MYSQL_LOG::purge_logs.

Removing redundant initialization.


sql/mysqld.cc:
  Removing redundant variable initialization.

Problem: some valid euc-kr characters were rejected because
condition checking multi-byte tail didn't allow 
multi-byte characters having the second byte in the ranges
[0x41..0x5A]  and [0x61..0x7A].

Fix: allow these byte ranges for mb tails
