this has already been closed by a note in the manual, now we
complete this by a note in "mysqldump --help"
client/mysqldump.c:
mention, in "mysqldump --help", of limitations reported as BUG#27850
"mysqldump --single-transaction does not work if TRUNCATE/DROP/RENAME/ALTER"
The new text is inspired from what the "mysqldump" section of the
manual now says about --single-transaction:
http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html
led to creating corrupted index.
Corrected fix. The new method called prepare2 is added to the select_create
class. As all preparations are done by the select_create::prepare function
it doesn't do anything. Slightly changed algorithm of calling the
start_bulk_insert function. Now it's called from the select_insert::prepare2
function when the SQL_BUFFER_RESULT flags is set.
The is_bulk_insert_mode flag is removed as it is not needed anymore.

This bug is actually two. The first one manifests itself on an EXPLAIN
SELECT query with nested subqueries that employs the filesort algorithm.
The whole SELECT under explain is marked as UNCACHEABLE_EXPLAIN to preserve
some temporary structures for explain. As a side-effect of this values of
nested subqueries weren't cached and subqueries were re-evaluated many
times. Each time buffer for filesort was allocated but wasn't freed because
freeing occurs at the end of topmost SELECT. Thus all available memory was
eaten up step by step and OOM event occur.
The second bug manifests itself on SELECT queries with conditions where
a subquery result is compared with a key field and the subquery itself also
has such condition. When a long chain of such nested subqueries is present
the stack overrun occur. This happens because at some point the range optimizer
temporary puts the PARAM structure on the stack. Its size if about 8K and
the stack is exhausted very fast.
Now the subselect_single_select_engine::exec function allows subquery result
caching when the UNCACHEABLE_EXPLAIN flag is set.
Now the SQL_SELECT::test_quick_select function calls the check_stack_overrun
function for stack checking purposes to prevent server crash.
mysql-test/t/subselect.test:
Added a test case for the bug#31048: Many nested subqueries may cause server crash.
mysql-test/r/subselect.result:
Added a test case for the bug#31048: Many nested subqueries may cause server crash.
sql/opt_range.cc:

bytes length.
The server has been modified to report warnings on truncation to
65536 bytes as usual.
sql/sql_string.cc:
Fixed bug #32282.
The well_formed_copy_nchars function returned an incorrect value
of copied bytes of the truncated input string: extra length of
the first truncated character added to the *from_end_pos pointer.
That has been fixed.
mysql-test/r/type_blob.result:
Added test case for bug #32282.
mysql-test/t/type_blob.test:
Added test case for bug #32282.
When the server was out of memory it crashed because of invalid memory access.
This patch adds detection for failed memory allocations and make the server
output a proper error message.
sql/mysqld.cc:
Don't try to push_warning from within push_warning. It will cause a recursion
until the stack is consumed.
If my_net_init fails (for example: because of OOM) the temporary vio object
might have been attached to the thd object already. This will cause a double
free on the vio object when the thd object is deleted later on and the server
will crash.
sql/sp_head.cc:
Added check for out-of-memory on a 'new' operation.
Refactored reset_lex method to return a error state code instead of void.
Initialize the mem-root with init_sql_alloc to get a basic error handler for
memory allocation problems. This alone won't prevent the server from crashing,
NULL pointers have to be accounted for as well.
sql/sp_head.h:
Use the throw() clause in operator new, to indicate to the compiler that
memory allocation can fail and return NULL, so that the compiler should
generate code to check for NULL before invoking C++ constructors, to be
crash safe.
sql/sql_base.cc:
Use init_sql_alloc to get basic out-of-memory error handling.
sql/sql_lex.h:
Use the throw() clause in operator new, to indicate to the compiler that

MySQL distributions contain a number of programs that are used only by
the MySQL test suite internally, i.e. they are not indended to be
invoked directly by a user. As a result, such programs are not
documented, do not have any built-in help or proper error reporting,
which may confuse users.
This patch fixes the problem with the following changes:
- mytest, libmysqltest and all references to them were removed from the
distribution since they are not used anymore
- bug25714 now displays an error message when run with incorrect
arguments or with the --help option
- mysql_client_test now does not call abort() in case of errors,
instead it does a clean exit() with a proper error status.

SPATIAL key is fine actually, but the chk_key() function
mistakenly returns error. It tries to compare checksums
of btree and SPATIAL keys while the checksum for the SPATIAL isn't
calculated (always 0). Same thing with FULLTEXT keys is handled
using full_text_keys counter, so fixed by counting both
SPATIAL and FULLTEXT keys in that counter.

Comparison of a BIGINT NOT NULL column with a constant arithmetic
expression that evaluates to NULL caused error 1048: "Column '...'
cannot be null".

NOT NULL field caused query errors.

This is a regression from 2007-05-18 when code to zero out the returned struct was

Don't use the "test-bt" target to run the tests on the debug server,
rather use "test-bt-debug".
There are two reasons for this:
1) Consistency with the "tar.gz" builds.
2) The tool that evaluates the build logs needs unique "--comment=" options in the log,
or else it will fail when it generates the test status summary.
