- Bug #24089: Race condition in fil_flush_file_spaces()


innobase/fil/fil0fil.c:
  Applied innodb-4.1-ss33
  
  Revision r33:
  innodb-4.1: Merge r1002 from innodb/trunk:
  
  fil_flush_file_spaces(): Copy the system->unflushed_spaces list to an
  array while holding the mutex.  This removes the crash-triggering
  race condition that was introduced when fixing Bug 15653.  (Bug #24089)

The Item_func_mod objects never had maybe_null set, so users had no reason 
to expect that they can be NULL, and may therefore deduce wrong results.
Now, set maybe_null.

  Make the variables that are referenced from the "command_arg" arrays static to please the NetWare compiler.
  Apparently the arrays can't reference local stack variables.

- Because my_seek actually is capable of returning an error code we should
  exploit that in the best possible way.
- There might be kernel errors or other errors we can't predict and capturing
  the return value of all system calls gives us better understanding of
  possible errors.

If the user has specified --max-connections=N or --table-open-cache=M
options to the server, a warning could be given that some values were
recalculated, and table-open-cache could be assigned greater value.

Note that both warning and increase of table-open-cache were totally
harmless.

This patch fixes recalculation code to ensure that table-open-cache will
be never increased automatically and that a warning will be given only if
some values had to be decreased due to operating system limits.

No test case is provided because we neither can't predict nor control
operating system limits for maximal number of open files.


sql/mysql_priv.h:
  Add constants for table_cache minimum and default values.
sql/mysqld.cc:
  Fix max_connections and table_cache_size re-computation.
