Added --with-gcov option to configure.pl and use that from SETUP.sh

Use [g]zip on core file if available, ignore if not
Skip if running named test, and print a line saying what it compressed.

message:
  Suppress the Bug #58815 (Bug #11765812) assertion failure.

  buf_page_get_gen(): Introduce BUF_GET_POSSIBLY_FREED for suppressing the
  check that the file page must not have been freed.

  btr_estimate_n_rows_in_range_on_level(): Pass BUF_GET_POSSIBLY_FREED and
  explain in the comments why this is needed and why it should be mostly
  harmless to ignore the problem. If InnoDB had always initialized all
  unused fields in data files, no problem would exist.

  This change does not fix the bug, it just "shoots the messenger".

Automerged bzr bundle from bug report into latest mysql-5.5.

In RBR and in case of converting blob fields, the space allocated
while unpacking into the conversion field was not freed after
copying from it into the real field.

We fix this by freeing the conversion field when the conversion
table is not needed anymore (on close_tables_to_lock).

from 5.1->5.5.

when selecting from I_S and views exist, in SP.

Symptoms: re-execution of prepared statement (or statement in a stored
routine) which read from one of I_S tables and which in order to fill
this I_S table had to open a view led to increasing memory consumption.

What happened in this situation was that during the process of view
opening for purpose of I_S filling view-related structures (like its
LEX) were allocated on persistent MEM_ROOT of prepared statement (or 
stored routine). Since this MEM_ROOT is not freed until prepared
statement deallocation (or expulsion of stored routine from the cache)
and code responsible for filling I_S is not able to re-use results of
view opening from previous executions this allocation ended up in
memory hogging.

This patch solves the problem by ensuring that when a view opened
for the purpose of I_S filling all its structures are allocated on
non-persistent runtime MEM_ROOT. This is achieved by activating a
temporary Query_arena bound to this MEM_ROOT.
Since this step makes impossible linking of view structures into
LEX of our prepared statement (or stored routine statement) this
patch also changes code filling I_S table to install a proxy LEX
before trying to open a view or a table. Consequently some code
which was responsible for backing-up/restoring parts of LEX when
view/table was opened during filling of I_S table became redundant
and was removed.

This patch doesn't contain test case for this bug as it is hard
to test memory hogging in our test suite.

The test case waits for master_pos_wait not to timeout, which
means that the deadlock between SQL and IO threads was 
succesfully and automatically dealt with.
      
However, very rarely, master_pos_wait reports a timeout. This
happens because the time set for master_pos_wait to wait was
too small (6 seconds). On slow test env this could be a 
problem.
      
We fix this by setting the timeout inline with the one used
in sync_slave_with_master (300 seconds). In addition we 
refactored the test case and refined some comments.

Issue:
While running embedded server, if client issues TEE command (\T foo/bar) and
"foo/bar" directory doesn't exist, it is suppose to give error. But it was
aborting.  This was happening because wrong error handler was being called.

Solution:
Modified calls to correct error handler. In embedded server case, there are 
two error handler (client and server) which are supposed to be called based 
on which context code is in. If it is in client context, client error handler
should be called otherwise server.

Test case:
Test case automation is not possible as current (following) code doesn't 
allow '\T' to be executed from command line (OR command read from a file):
[client/mysql.cc]
...
 static int
 com_tee(String *buffer __attribute__((unused)),
         char *line __attribute__((unused)))
 {
   char file_name[FN_REFLEN], *end, *param;

   if (status.batch) << THIS IS TRUE WHILE EXECUTING FROM COMMAND LINE.
      return 0;
 ...
So, not adding test case in GA. WIll add a test case in mysql-trunk after 
removing above code so that this could be properly tested before GA.

or Oracle Bug #11766513.

trx_undo_free_prepared(): Do not acquire or release trx->rseg->mutex.
This code is invoked in the single-threaded part of shutdown, therefore
a mutex is not needed.

There are two problems:
1. There is a missing check for 'year' parameter(year can not be greater than 9999) in
   makedate function. fix: added check that year can not be greater than 9999.
2. There is a missing check for zero date in from_days() function.
   fix: added zero date check into Item_func_from_days::get_date()
   function.

node->modification_counter == node->flush_counter

This bug (an assertion failure during a crash-like shutdown)
was introduced by the fix of
Bug#12323643 Clean up the InnoDB thread shutdown and assertions (WL#5136).

fil_node_close_file(): Relax the failing assertion
when innodb_fast_shutdown=2.

In sql_class.cc, 'row_count', of type 'ha_rows', was used as last argument for
ER_TRUNCATED_WRONG_VALUE_FOR_FIELD which is
"Incorrect %-.32s value: '%-.128s' for column '%.192s' at row %ld".
So 'ha_rows' was used as 'long'.
On SPARC32 Solaris builds, 'long' is 4 bytes and 'ha_rows' is 'longlong' i.e. 8 bytes.
So the printf-like code was reading only the first 4 bytes.
Because the CPU is big-endian, 1LL is 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01
so the first four bytes yield 0. So the warning message had "row 0" instead of
"row 1" in test outfile_loaddata.test:
-Warning	1366	Incorrect string value: '\xE1\xE2\xF7' for column 'b' at row 1
+Warning	1366	Incorrect string value: '\xE1\xE2\xF7' for column 'b' at row 0

All error-messaging functions which internally invoke some printf-life function
are potential candidate for such mistakes.
One apparently easy way to catch such mistakes is to use
ATTRIBUTE_FORMAT (from my_attribute.h).
But this works only when call site has both:
a) the format as a string literal
b) the types of arguments.
So:
  func(ER(ER_BLAH), 10);
will silently not be checked, because ER(ER_BLAH) is not known at
compile time (it is known at run-time, and depends on the chosen
language).
And
  func("%s", a va_list argument);
has the same problem, as the *real* type of arguments is not
known at this site at compile time (it's known in some caller).
Moreover,
  func(ER(ER_BLAH));
though possibly correct (if ER(ER_BLAH) has no '%' markers), will not
compile (gcc says "error: format not a string literal and no format
arguments").

Consequences:
1) ATTRIBUTE_FORMAT is here added only to functions which in practice
take "string literal" formats: "my_error_reporter" and "print_admin_msg".
2) it cannot be added to the other functions: my_error(),
push_warning_printf(), Table_check_intact::report_error(),
general_log_print().

To do a one-time check of functions listed in (2), the following
"static code analysis" has been done:
1) replace
  my_error(ER_xxx, arguments for substitution in format)
with the equivalent
  my_printf_error(ER_xxx,ER(ER_xxx), arguments for substitution in
format),
so that we have ER(ER_xxx) and the arguments *in the same call site*
2) add ATTRIBUTE_FORMAT to push_warning_printf(),
Table_check_intact::report_error(), general_log_print()
3) replace ER(xxx) with the hard-coded English text found in
errmsg.txt (like: ER(ER_UNKNOWN_ERROR) is replaced with
"Unknown error"), so that a call site has the format as string literal
4) this way, ATTRIBUTE_FORMAT can effectively do its job
5) compile, fix errors detected by ATTRIBUTE_FORMAT
6) revert steps 1-2-3.
The present patch has no compiler error when submitted again to the
static code analysis above.
It cannot catch all problems though: see Field::set_warning(), in
which a call to push_warning_printf() has a variable error
(thus, not replacable by a string literal); I checked set_warning() calls
by hand though.

See also WL 5883 for one proposal to avoid such bugs from appearing
again in the future.

The issues fixed in the patch are:
a) mismatch in types (like 'int' passed to '%ld')
b) more arguments passed than specified in the format.
This patch resolves mismatches by changing the type/number of arguments,
not by changing error messages of sql/share/errmsg.txt. The latter would be wrong,
per the following old rule: errmsg.txt must be as stable as possible; no insertions
or deletions of messages, no changes of type or number of printf-like format specifiers,
are allowed, as long as the change impacts a message already released in a GA version.
If this rule is not followed:
- Connectors, which use error message numbers, will be confused (by insertions/deletions
of messages)
- using errmsg.sys of MySQL 5.1.n with mysqld of MySQL 5.1.(n+1)
could produce wrong messages or crash; such usage can easily happen if
installing 5.1.(n+1) while /etc/my.cnf still has --language=/path/to/5.1.n/xxx;
or if copying mysqld from 5.1.(n+1) into a 5.1.n installation.
When fixing b), I have verified that the superfluous arguments were not used in the format
in the first 5.1 GA (5.1.30 'bteam@astra04-20081114162938-z8mctjp6st27uobm').
Had they been used, then passing them today, even if the message doesn't use them
anymore, would have been necessary, as explained above.

FREED IN FLUSH_READ_LOCK (VALGRIND WARNING).

The problem was that under some circustances the memory allocated
for Query_tables_list::sroutines was not freed properly.
The cause of this problem was the absence of
LEX::restore_backup_query_tables_list() call in one of the branches
in mysql_table_grant() function.
