c212cb25ed BUG#19188: incorrect temporary table name of DROP query in replication
A pattern to generate binlog for DROPped temp table in close_temporary_tables
  was buggy: could not deal with a grave-accent-in-name table.

  The fix exploits `append_identifier()' for quoting and duplicating accents.

  more correct internal table emulation; typo of @@session in bug#17263.

  is added to answer wheather temporary table was created explicitly.
sql/sql_base.cc:
  Utilizing `append_identifier' to quote. `close_temporary_tables' once again recoded
  I hope to become much simplier than previously. No-binlog branch is separated completely the
  rest that adopts String's methods.

c23c38fa31 BUG#14157: utf8 encoding in binlog without set character_set_client e.g DROP temporary
Binlog lacks encoding info about DROPped temporary table.

Idea of the fix is to switch temporary to system_charset_info when a temporary table
is DROPped for binlog. Since that is the server, that automatically, but not the client, who generates the query
the binlog should be updated on the server's encoding for the coming DROP.
The `write_binlog_with_system_charset()' is introduced to replace similar problematic places in the code.

375749b8af Fixed bug #14927.
A query with a group by and having clauses could return a wrong
result set if the having condition contained a constant conjunct 
evaluated to FALSE.
It happened because the pushdown condition for table with
grouping columns lost its constant conjuncts.
Pushdown conditions are always built by the function make_cond_for_table
that ignores constant conjuncts. This is apparently not correct when
constant false conjuncts are present.

  "Impossible HAVING" in the last column.

c13144722a BUG#16798: Inapplicable ref_or_null query plan and bad query result on random occasions
The bug was as follows: When merge_key_fields() encounters "t.key=X OR t.key=Y" it will 
try to join them into ref_or_null access via "t.key=X OR NULL". In order to make this 
inference it checks if Y<=>NULL, ignoring the fact that value of Y may be not yet known.

The fix is that the check if Y<=>NULL is made only if value of Y is known (i.e. it is a
constant).
TODO: When merging to 5.0, replace used_tables() with const_item() everywhere in merge_key_fields().

4ab4631b06 Bug#19136: Crashing log-bin and uninitialized user variables in a derived table
The reason of the bug is in that `get_var_with_binlog' performs missed
assingment of
the variables as side-effect. Doing that it eventually calls
`free_underlaid_joins' to pass as an argument `thd->lex->select_lex' of the lex
which belongs to the user query, not 
to one which is emulated i.e SET @var1:=NULL.


`get_var_with_binlog' is refined to supply a temporary lex to sql_set_variables's stack.

d300ceea3f Bug#19025 4.1 mysqldump doesn't correctly dump "auto_increment = [int]"
mysqldump / SHOW CREATE TABLE will show the NEXT available value for
the PK, rather than the *first* one that was available (that named in
the original CREATE TABLE ... AUTO_INCREMENT = ... statement).

This should produce correct and robust behaviour for the obvious use
cases -- when no data were inserted, then we'll produce a statement
featuring the same value the original CREATE TABLE had; if we dump
with values, INSERTing the values on the target machine should set the
correct next_ID anyway (and if not, we'll still have our AUTO_INCREMENT =
... to do that). Lastly, just the CREATE statement (with no data) for
a table that saw inserts would still result in a table that new values
could safely be inserted to).

There seems to be no robust way however to see whether the next_ID
field is > 1 because it was set to something else with CREATE TABLE
... AUTO_INCREMENT = ..., or because there is an AUTO_INCREMENT column
in  the table (but no initial value was set with AUTO_INCREMENT = ...)
and then one or more rows were INSERTed, counting up next_ID. This
means that in both cases, we'll generate an AUTO_INCREMENT =
... clause in SHOW CREATE TABLE / mysqldump.  As we also show info on,
say, charsets even if the user did not explicitly give that info in
their own CREATE TABLE, this shouldn't be an issue.

As per above, the next_ID will be affected by any INSERTs that have
taken place, though.  This /should/ result in correct and robust
behaviour, but it may look non-intuitive to some users if they CREATE
TABLE ... AUTO_INCREMENT = 1000 and later (after some INSERTs) have
SHOW CREATE TABLE give them a different value (say, CREATE TABLE
... AUTO_INCREMENT = 1006), so the docs should possibly feature a
caveat to that effect.

It's not very intuitive the way it works now (with the fix), but it's
*correct*.  We're not storing the original value anyway, if we wanted
that, we'd have to change on-disk representation?

If we do dump/load cycles with empty DBs, nothing will change.  This
changeset includes an additional test case that proves that tables
with rows will create the same next_ID for AUTO_INCREMENT = ... across
dump/restore cycles.

Confirmed by support as likely solution for client's problem.

mysql-test/t/auto_increment.test:
  test for creation of AUTO_INCREMENT=... clause
mysql-test/t/mysqldump.test:
  show that AUTO_INCREMENT=... will survive dump/restore cycles
sql/sql_show.cc:
  Add AUTO_INCREMENT=... to output of SHOW CREATE TABLE if there is an
  AUTO_INCREMENT column, and NEXT_ID > 1 (the default).  We must not print
  the clause for engines that do not support this as it would break the
  import of dumps, but as of this writing, the test for whether
  AUTO_INCREMENT columns are allowed and wether AUTO_INCREMENT=...
  is supported is identical, !(file->table_flags() & HA_NO_AUTO_INCREMENT))
  Because of that, we do not explicitly test for the feature,
  but may extrapolate its existence from that of an AUTO_INCREMENT column.
