sql/sql_select.cc:
According to the conclusion made in the previous patch, we can widen
the range of cases when JOINs are fully freed early, and include
subqueries to it.
sql/sql_select.cc:
This assert is not relevant because:
- the correct assert is DBUG_ASSERT(! (full && sl->uncacheable))
(prevents freeing of uncacheable JOINs), it breaks view.test
- it seems we can free internal JOINs, even if they are uncacheable:
if the top level join is evaluated, we're not going to need the
internal joins any more
The reason it happened was that both, JOIN::cleanup() and JOIN::join_free(),
went over all nested joins and called cleanup/join_free for them.
For that:
- split recursive and non-recursive parts of JOIN::cleanup() and
JOIN::join_free()
- rename JOIN::cleanup to JOIN::destroy, as it actually destroys its
argument
- move the recursive part of JOIN::cleanup to st_select_lex::cleanup
- move the non-recursive part of JOIN::join_free to the introduced
method JOIN::cleanup().
sql/sql_lex.h:
Add st_select_lex::cleanup, a counterpart of st_select_lex_unit::cleanup()
sql/sql_select.cc:
- remove two unused arguments from return_zero_rows
- split JOIN::join_free and JOIN::cleanup to recursive and non-recursive
parts.
- note, the assert in JOIN::join_free _does_ fail in having.test.
We have two options: a) propagate `full' flag to the nested joins.
We did it before, and this patch didn't change it. If so, we
can end up cleaning up an uncacheable JOIN (that is, the join that
we might need again).
b) evaluate own 'full' flag on every level. In this case, we might
end up with tables freed in mysql_unlock_read_tables, but not
cleaned up properly, and this may be even worse. The test suite
passes with both approaches, but not with the assert.
sql/sql_select.h:
- declarations for JOIN::cleanup() and JOIN::join_free()
sql/sql_union.cc:
Add st_select_lex::cleanup, a counterpart of st_select_lex_unit::cleanup():
move the recursive part of JOIN::cleanup to it.

Added 64-bit extensions, comments, extended statistics
and trace prints.
include/my_base.h:
Bug#8321 - myisampack bug in compression algorithm
Added a comment.
myisam/mi_packrec.c:
Bug#8321 - myisampack bug in compression algorithm
Fixed a function comment.
myisam/myisampack.c:
Bug#8321 - myisampack bug in compression algorithm
Enlarged the variables which hold Huffman codes to
ulonglong and adjusted the functions accordingly.
Added test code for long Huffman codes.
Enlarged the distinct column values buffer (tree_buff)
and added checks to stay in its range.
Added statistics and trace prints.
Added a lot of comments.
mysys/tree.c:
Bug#8321 - myisampack bug in compression algorithm
Added a check against overflow of the tree element count.
The tree element count is only 31 bits, but sometimes
used for big numbers. There is however no application yet,
which relies on exact tree element counts.
Wrong comparing method were choosen which results in false comparison.
Make Item_bool_func2::fix_length_and_dec() to get type and field from
real_item() to make REF_ITEM pass the check.
sql/item_cmpfunc.cc:

Moved the key statistics update to info().
The table is not locked in open(). This made wrong stats possible.
No test case for the test suite.
This happens only with heavy concurrency.
A test script is added to the bug report.
mysql-test/r/heap_hash.result:
Bug#10178 - failure to find a row in heap table by concurrent UPDATEs
Updated test results to reflect the new statistics behaviour.
mysql-test/t/heap_hash.test:
Bug#10178 - failure to find a row in heap table by concurrent UPDATEs
Added a FLUSH TABLES to avoid statistics differences between normal
and ps-protocol tests.
sql/ha_heap.cc:
Bug#10178 - failure to find a row in heap table by concurrent UPDATEs
Moved the key statistics update to info().
The table is not locked in open(). This made wrong stats possible.

Bug#10178 - failure to find a row in heap table by concurrent UPDATEs
Added an element to track the validity of the key statistics.

it can use it to switch to only quoting apostrophes by doubling
them when it is in effect. (Bug #10214)
include/my_sys.h:

libmysql/libmysql.c:
Use SERVER_STATUS_NO_BACKSLASH_ESCAPES in server_status to determine
how mysql_real_escape_string() should do quoting.
mysys/charset.c:
Add new escape_quotes_for_mysql() function that only quotes
apostrophes by doubling them up.
sql/set_var.cc:
Set SERVER_STATUS_NO_BACKSLASH_ESCAPES when MODE_NO_BACKSLASH_ESCAPES
changes.
sql/sql_class.cc:
Set SERVER_STATUS_NO_BACKSLASH_ESCAPES when necessary on thread creation.
tests/mysql_client_test.c:
Add new test for sending NO_BACKSLASH_ESCAPES as part of server_status.
