Assert in Diagnostics_area::set_ok_status() for XA COMMIT

This assert was triggered if XA COMMIT was issued when an XA transaction
already had encountered an error (e.g. a deadlock) which required
the XA transaction to be rolled back.

In general, the assert is triggered if a statement tries to send OK to
the client when an error has already been reported. It was triggered
in this case because the trans_xa_commit() function first reported an
error, then rolled back the transaction and finally returned FALSE,
indicating success. Since trans_xa_commit() reported success,
mysql_execute_command() tried to report OK, triggering the assert.

This patch fixes the problem by fixing trans_xa_commit() to return TRUE
if it encounters an error that requires rollback, even if the rollback
itself is successful.

Test case added to xa.test.

With this change, there will be new files "INFO_SRC"
and "INFO_BIN", which describe the source and the
binaries.
They will be contained in all packages:
- in "tar.gz" and derived packages, in "docs/",
- in RPMs, in "/usr/share/doc/packages/MySQL-server".

"INFO_SRC" is also part of a source tarball.
It gives the version as exact as possible, preferably
by calling "bzr version-info" on the source tree.
If that is not possible, it just contains the three
level version number.

"INFO_BIN" contains some info when and where the
binaries were built, the options given to the compiler,
and the flags controlling the included features.

The tests (test "mysql" in the main suite) are extended
to verify the existence of both "INFO_SRC" and "INFO_BIN",
as well as some of the expected contents.


CMakeLists.txt:
  For the new files describing the source and the build
  ("INFO_SRC" and "INFO_BIN"), we need a new file
  "cmake/info_macros.cmake.in" with the build rules.
  
  1) This file must be configured with the current variables.
  
  2) "INFO_SRC" can be created during the cmake phase,
     but this should be repeated with each "make" to
  protect against a developer doing only "make" after
  a "bzr pull" (or "bzr commit").
  So have it both as a cmake rule and as a custom target.
  
  3) "INFO_BIN" must be created during the make phase
     only, because it contains information from files
  which will be written at the end of the cmake phase only.
  Therefore, it must be a custom target which is included
  in all "make" targets.
  
  4) The resulting "INFO_*" files must be included in packages.
cmake/info_bin.cmake:
  This is the file to create "INFO_BIN",
  by calling the "CREATE_INFO_BIN()" macro.
  
  It must be a separate file, so that the macro
  definitions can be included in other cmake scripts
  without that file inclusion causing a side effect,
  the macro call.
  That call would modify the source tree which should
  be trated read-only.
cmake/info_macros.cmake.in:
  This new file contains the macros to create the
  "INFO_*" files during various steps of the build,
  the calls will be at other places.
  
  1) For source: If running from a BZR tree, always create
     (update) "INFO_SRC" by running "bzr version-info".
     Outside a BZR tree, try to take it from exported
     sources, and create it only if missing, in that
     case put the three level version number into it.
  
  2) "INFO_BIN" contains
     - date/time and host name of the build host,
     - information about the platform,
     - information about the C and CXX compiler
       and the options given to them (Unix only),
     - the feature flags as reported by "cmake -L".
cmake/info_src.cmake:
  This is the file to create "INFO_SRC",
  by calling the "CREATE_INFO_SRC()" macro.
  
  It must be a separate file, so that the macro
  definitions can be included in other cmake scripts
  without that file inclusion causing a side effect,
  the macro call.
  That call would modify the source tree which should
  be trated read-only.
cmake/make_dist.cmake.in:
  Create a "VERSION_src" file during "make dist".
  
  In case it already exists from a preceding "cmake" run
  or tree export (which is quite likely), a new
  "make dist" must not modify it.

An after-fix to workaround different metadata in "mtr --ps" output.

batch_readline_init() was modified - make check for 
type of file for input stream unless target platform
is WINDOWS since on this platform S_IFBLK is undefined.

Reverse DNS lookup of "localhost" returns "broadcasthost" on Snow Leopard (Mac), and NULL on most others.
Simply ignore the output, as this is not an essential part of UDF testing.

batch_readline_init() was modified - return an error
if the input source is a directory or a block device.

This follow-up is necessary because on some platforms,
such as Solaris, call to read() from directory may be
successful.

Test failed on a certain Linux platform in automated environment. It turns out that this platform has an old version of Perl modules DBI and DBD::mysql installed, as well as the OS itself being relatively old.
Allowing error code 11 to be returned from mysqlhotcopy on expected error seems harmless and will make the test pass also with older libraries.

Also fix bug#59110: Memory leak of QUICK_SELECT_I allocated memory.
Includes Jørgen Lølands review comments.
      
Root cause of these bugs are that test_if_skip_sort_order() decided to
revert the 'skip_sort_order' descision (and use filesort) after the
query plan has been updated to reflect a 'skip' of the sort order.
      
This might happen in 'check_reverse_order:' if we have a 
select->quick which could not be made descending by appending 
a QUICK_SELECT_DESC. ().
      
The original 'save_quick' was then restored after the QEP has been modified,
which caused:
      
  - An incorrect 'precomputed_group_by= TRUE' may have been set, 
    and not reverted, as part of the already modifified QEP (Bug#59308)
  - A 'select->quick' might have been created which we fail to delete (bug#59110).
      
This fix is a refactorication of test_if_skip_sort_order() where all logic
related to modification of QEP (controlled by argument 'bool no_changes'), is
moved to the end of test_if_skip_sort_order(), and done after *all* 'test_if_skip'
checks has been performed - including the 'check_reverse_order:' checks.
      
The refactorication above contains now intentional changes to the logic which 
has been moved to the end of the function.
      
Furthermore, a smaller part of the fix address the handling of the 
select->quick objects which may already exists when we call 
'test_if_skip_sort_order()' (save_quick) -and
new select->quick's created during test_if_skip_sort_order():
      
  - Before new select->quick may be created by calling ::test_quick_select(), we
    set 'select->quick= 0' to avoid that ::test_quick_select() prematurely
    delete the save_quick's. (After this call we may have both a 'save_quick' 
    and 'select->quick')
      
  - All returns from ::test_if_skip_sort_order() where we may have both a
    'save_quick' and a 'select->quick' has been changed to goto's to the
    exit points 'skiped_sort_order:' or 'need_filesort:' where we
    decide which of the QUICK_SELECT's to keep, and delete the other.

if the standard input is a directory.

The problem is that mysql monitor try to read from stdin without
checking input source type.

The solution is to stop reading data from standard input if a call
to read(2) failed.

A new test case was added into mysql.test.

client/my_readline.h:
  Data members error and truncated was added to LINE_BUFFER structure.
  These data members used instead of out parameters in functions
  batch_readline, intern_read_line.
client/mysql.cc:
  read_and_execute() was modified: set status.exit_status to 1
  when the error occured while reading the next command line in
  non-interactive mode. Also the value of the truncated attribute
  of structure LINE_BUFF is taken into account only for non-iteractive mode.
client/readline.cc:
  intern_read_line() was modified: cancel reading from input if
  fill_buffer() returns -1, e.g. if call to read failed.
  batch_readline was modified: set the error data member of LINE_BUFFER
  structure to value of my_errno when system error happened during call
  to my_read/my_realloc.
mysql-test/t/mysql.test:
  Test for bug#57450 was added.

Replace --debug with --loose-debug to prevent failure exit
Update: added workaround for 50627, skip all debugging of mysqlbinlog

Add suppressions for a bogus valgrind warnings.

handling.

The problem was that parsing of nested regular expression involved
recursive calls. Such recursion didn't take into account the amount of
available stack space, which ended up leading to stack overflow crashes.

mysql-test/t/not_embedded_server.test:
  Added test for bug#58026.
regex/my_regex.h:
  added pointer to function as last argument of my_regex_init() for check
  enough memory in stack.
regex/regcomp.c:
  p_ere() was modified: added call to function for check enough memory
  in stack. Function for check available stack space specified by
  global variable my_regex_enough_mem_in_stack. This variable set to
  NULL for embedded mysqld and to a pointer to function
  check_enough_stack_size otherwise.
regex/reginit.c:
  my_regex_init was modified: pass a pointer to a function for check
  enough memory in stack space. Reset this pointer to NULL in my_regex_end.
sql/mysqld.cc:
  Added function check_enough_stack_size() for check enough memory in stack.
  Passed this function as second argument to my_regex_init. For embedded 
  mysqld passed NULL as second argument.

When fixing the 27072 bug, the shell snippets running before/after
a RPM upgrade got expanded to look at files in the data directory
and at the PID file.
In this expansion, the standard locations were used.

There are users who configure their installations to use non-standard
locations for the data directory, the PID file, and other objects.
For these users, the fix of 27072 did not work.
As a result, the fact that a server was running at upgrade start was
not noticed, and the new server was not started after the upgrade.

With this patch, the shell snippets now try to get these locations
from "my_print_defaults" before falling back to the defaults.
Now, the fact that the old server is running is again noticed (even
with non-standard locations), and the new server is started.

Also, the upgrade log is written to the correct data directory.

support-files/mysql.spec.sh:
  See the global comment for the purpose of this change.
  
  In tests on SuSE 11, it was found necessary to use the full path name
  of "my_print_defaults", it seems $PATH die not include "/usr/bin".

      
There is one part of the test case that needs to break
and re-establish the circular topology. For this the test
stops the slave threads on a couple of servers and restarts
them with START SLAVE. However, no check is done on the
status of the IO or SQL threads before proceeding with
the subsequent commands.
      
Because rpl_only_running_threads is set to 1 this can lead
to silently not syncing all slave threads as expected, 
ultimately resulting in unexpected results (and consequently
on a failing test run).
      
We fix this by replacing the START SLAVE instructions with
calls to --source include/start_slave.inc, which will wait
for the slave threads to be running (show 'Yes' in 
Slave_IO|SQL_Running fields of SHOW SLAVE STATUS) before 
proceeding. Additionally, we change rpl_sync.inc to make the
IO thread report that it is running when its running status
is any other than 'No'.

Bug #55755 : Date STD variable signness breaks server on FreeBSD and OpenBSD

* Added a check to configure on the size of time_t
* Created a macro to check for a valid time_t that is safe to use with datetime 
  functions and store in TIMESTAMP columns.
* Used the macro consistently instead of the ad-hoc checks introduced by 52315
* Fixed compliation warnings on platforms where the size of time_t is smaller than
  the size of a long (e.g. OpenBSD 4.8 64 amd64).

Bug #52315: utc_date() crashes when system time > year 2037

* Added a correct check for the timestamp range instead of just variable size check to
SET TIMESTAMP.
* Added overflow checking before converting to time_t. 
* Using a correct localized error message in this case instead of the generic error.
* Added a test suite.
* fixed the checks so that they check for unsigned time_t as well. Used the checks 
  consistently across the source code.
* fixed the original test case to expect the new error code.

btr_rec_get_field_ref_offs(), btr_rec_get_field_ref(): New functions.
Get the pointer to an externally stored field.

btr_cur_set_ownership_of_extern_field(): Assert that the BLOB has not
already been disowned.

btr_store_big_rec_extern_fields(): Rename to
btr_store_big_rec_extern_fields_func() and add the debug parameter
update_in_place. All pointers to externally stored columns in the
record must either be zero or they must be pointers to inherited
columns, owned by this record or an earlier record version. For any
BLOB that is stored, the BLOB pointer must previously have been
zero. When the function completes, all BLOB pointers must be nonzero
and owned by the record.

primary_key_no == 0".

Attempt to create InnoDB table with non-nullable column of
geometry type having an unique key with length 12 on it and
with some other candidate key led to server crash due to
assertion failure in both non-debug and debug builds.

The problem was that such a non-candidate key could have
been sorted as the first key in table/.FRM, before any legit
candidate keys. This resulted in assertion failure in InnoDB
engine which assumes that primary key should either be the
first key in table/.FRM or should not exist at all.

The reason behind such an incorrect sorting was an wrong
value of Create_field::key_length member for geometry field
(which was set to its pack_length == 12) which confused code
in mysql_prepare_create_table(), so it would skip marking
such key as a key with partial segments.

This patch fixes the problem by ensuring that this member
gets the same value of Create_field::key_length member as 
for other blob fields (from which geometry field class is
inherited), and as result unique keys on geometry fields
are correctly marked as having partial segments.


mysql-test/include/gis_keys.inc:

  primary_key_no == -1 || primary_key_no == 0".

mysql-test/suite/innodb_plugin/r/innodb_gis.result:
  Added test case for bug #58650 "Failing assertion:
  primary_key_no == -1 || primary_key_no == 0".
sql/field.cc:
  Changed Create_field::create_length_to_internal_length() to
  correctly set Create_field::key_length member for geometry
  fields. Similar to the blob types key_length for such fields
  should be the same as length and not field's packed length
  (which is always 12 for geometry).
  
  As result of this change code handling table creation now
  always correctly identifies btree/unique keys on geometry
  fields as partial keys, so such keys can't be erroneously
  treated as candidate keys and sorted in keys array in .FRM
  before legit candidate keys.
  
  This fixes bug #58650 "Failing assertion: primary_key_no ==
  -1 || primary_key_no == 0" in which incorrect candidate key
  sorting led to assertion failure in InnoDB code.
