This is the fix for 5.5, where the behaviour on both installation
and upgrade is changed:
On installation, we do not start the server, to allow automated
installs (which happen in some indeterminate machine status).
If the server was stopped when the upgrade begins, we assume the
administrator is taking manual action, so we do not start the (new)
server at the end of the upgrade.
We still install the start/stop script, so it will be started on reboot.


support-files/mysql.spec.sh:
  In the "pre" section of the spec file, check the server status, and write
  the result to a file.
  In the "post" section, evaluate the status file, and start the server if
  it was running during status analysis.
  In 5.5, we do *not* start the server if there is no status file (which will happen on first installation, when there is no data directory yet).

This is the fix for 5.1, where only the behaviour on upgrade is changed:
If the server was stopped when the upgrade begins, we assume the
administrator is taking manual action, so we do not start the (new)
server at the end of the upgrade.
We still install the start/stop script, so it will be started on reboot.

Revision ID of the patch: marc.alff@oracle.com-20100608124148-lr1ult7lwo75niev

Prior to this fix, mysys mutexes such as THR_LOCK_lock could be initialized
twice by a call to my_init().
The root cause was out of place initialization in my_basic_init(),
calling my_thread_global_init().

With this fix,
- my_basic_init() properly initializes the mutex implementation itself,
for SAFE or FAST mutexes, and for platform dependent initializations,
before initialiazing a mutex.
- my_init() properly initializes mysys mutexes once,
when making the first call to my_thread_global_init().

Also, update a few cases missed by the initial patch.

client/mysqltest.cc:
  Remove trailing comma.
include/my_alloc.h:
  Do not use wrapper.
include/mysql.h.pp:
  Update ABI file.
plugin/semisync/semisync_master.h:
  Initialize variable.
sql/debug_sync.cc:
  Use C linkage.

Fix various mismatches between function's language linkage. Any
particular function that is declared in C++ but should be callable
from C must have C linkage. Note that function types with different
linkages are also distinct. Thus, if a function type is declared in
C code, it will have C linkage (same if declared in a extern "C"
block).

client/mysql.cc:
  Mismatch between prototype and declaration.
client/mysqltest.cc:
  mysqltest used to be C code. Use C linkage where appropriate.
cmd-line-utils/readline/input.c:
  Isolate unreachable code.
include/my_alloc.h:
  Function type must have C linkage.
include/my_base.h:
  Function type must have C linkage.
include/my_global.h:
  Add helper macros to avoid spurious namespace indentation.
include/mysql.h.pp:
  Update ABI file.
mysys/my_gethwaddr.c:
  Remove stray carriage return and fix coding style.
plugin/semisync/semisync_master_plugin.cc:
  Callback function types have C linkage.
plugin/semisync/semisync_slave_plugin.cc:
  Callback function types have C linkage.
sql/derror.cc:
  Expected function type has C linkage.
sql/field.cc:
  Use helper macro and fix indentation.
sql/handler.cc:
  Expected function type has C linkage.
sql/item_sum.cc:
  Correct function linkages. Remove now unnecessary cast.
sql/item_sum.h:
  Add prototypes with the appropriate linkage as otherwise they
  are distinct.
sql/mysqld.cc:
  Wrap functions in C linkage mode.
sql/opt_range.cc:
  C language linkage is ignored for class member functions.
sql/partition_info.cc:
  Add wrapper functions with C linkage for class member functions.
sql/rpl_utility.h:
  Use helper macro and fix indentation.
sql/sql_class.cc:
  Change type of thd argument -- THD is a class.
  Use helper macro and fix indentation.
sql/sql_class.h:
  Change type of thd argument -- THD is a class.
sql/sql_select.cc:
  Expected function type has C linkage.
sql/sql_select.h:
  Move prototype to sql_test.h
sql/sql_show.cc:
  Expected function type has C linkage.
sql/sql_test.cc:
  Fix required function prototype and fix coding style.
sql/sql_test.h:
  Removed unnecessary export and add another.
storage/myisammrg/ha_myisammrg.cc:
  Expected function type has C linkage.
storage/perfschema/pfs.cc:
  PSI headers are declared with C language linkage, which also
  applies to function types.

merge of patch for bug#52913 from 5.1-bugteam to trunk-bugfixing. Changed $basedir to $bindir in mysql-test-run.pl.

mysql-test/include/not_var_link.inc:
  Chop off /$child_num before testing if "var" is a symlink

      Problems:
      - regression (compating to version 5.1) in metadata for BLOB types

errors
            
In the fix of BUG#39934 in 5.1-rep+3, errors are generated when
binlog_format=row and a statement modifies a table restricted to
statement-logging (ER_BINLOG_ROW_MODE_AND_STMT_ENGINE); or if
binlog_format=statement and a statement modifies a table restricted to
row-logging (ER_BINLOG_STMT_MODE_AND_ROW_ENGINE).
            
However, some DDL statements that lock tables (e.g. ALTER TABLE,
CREATE INDEX and CREATE TRIGGER) were causing spurious errors,
although no row might be inserted into the binary log.
            
To fix the problem, we tagged statements that may generate
rows into the binary log and thence the warning messages are
only printed out when the appropriate conditions hold and rows
might be changed.

sql/log_event.cc:
  Reorganized the Query_log_event's constructor based on the
  CF_CAN_GENERATE_ROW_EVENTS flag and as such any statement
  that has the associated flag should go through a cache
  before being written to the binary log.
sql/share/errmsg-utf8.txt:
  Improved the error message ER_BINLOG_UNSAFE_MIXED_STATEMENT according to Paul's
  suggestion.
sql/sql_class.cc:
  Created a hook to be used by innodb that checks if a statement
  may write rows to the binary log. In other words, if it has
  the CF_CAN_GENERATE_ROW_EVENTS flag associated.
sql/sql_class.h:
  Defined the CF_CAN_GENERATE_ROW_EVENTS flag.
sql/sql_parse.cc:
  Updated the sql_command_flags and added a function to check the 
  CF_CAN_GENERATE_ROW_EVENTS.
sql/sql_parse.h:
  Added a function to check the CF_CAN_GENERATE_ROW_EVENTS.
storage/innobase/handler/ha_innodb.cc:
  Added a call to the hook thd_generates_rows().
storage/innobase/handler/ha_innodb.h:
  Defined an external reference to the hook thd_generates_rows().

- Ported relevant changes from the upstream version to not
break strict-aliasing rules and to fix compiler warnings and
and infinite loops caused by that issue.

- Fixed compilation with Honor_FLT_ROUNDS defined.

- Fixed an unused variable warning.

breaks
      
When a "CREATE TEMPORARY TABLE SELECT * FROM" was executed the OPTION_KEEP_LOG was
not set into the thd->variables.option_bits. For that reason, if the transaction
had updated only transactional engines and was rolled back at the end (.e.g due to
a deadlock) the changes were not written to the binary log, including the creation
of the temporary table.
      
To fix the problem, we have set the OPTION_KEEP_LOG into the
thd->variables.option_bits when a "CREATE TEMPORARY TABLE
SELECT * FROM" is executed.
