port from mysql-next (5.4) to mysql-next-mr-bugfixing (5.5/5.6?)

2755 Konstantin Osipov	2008-11-27
Bug#32115 will remove the pre-requisite to initialize LEX to open tables.
This dependency was added in 5.1 and was supposed to be removed in 6.0.
Remove asserts and initialization of LEX in places where we don't deal
with partitioned tables.

sql/sp_head.cc:
  Fix a typo.

Backport of the fix for BUG#40368 "mysqld_safe not honouring underscore same as dash on server options" from 6.0
(revision-id:guilhem@mysql.com-20090505113602-l12kxupeatve18dh).
Such bug led "mysqld_safe --core_file_size=#" to not work because mysqld_safe wouldn't recognize
that "ulimit -c" is needed; only --core-file-size=# worked. Same for --open_files_limit and other
options with _ where mysqld_safe needs to do something more than passing to mysqld.
Original fix by Erik Ljungstrom erik at ibiblio dot org ; slightly modified here.
Tested on all internally accessible Unix.

mysql-test/r/sp-error.result:
  Update test case result.
mysql-test/t/dirty_close.test:
  Dirty close does not work under embedded.
mysql-test/t/sp-error.test:
  Use the specific error number so it won't catch
  other non-fatal errors.

      
Just change mysql_foo to mysql_cv_foo for one cache-id variable name.  There
was only one bad variable name, present in 5.0 and 5.1, but not in the -pe
branch.


Backported to 5.6.0  (mysql-next-mr-runtime)

           STRING_RESULT argument

There is a "magic" number for precision : NOT_FIXED_DEC. 
This means that the precision is not a fixed number.
But this constant was re-defined in several files and 
was not available to the UDF developers.
 
Moved the NOT_FIXED_DEC definition to the correct header
and removed the redundant definitions.

Backported to 5.6.0  (mysql-next-mr-runtime)

client/sql_string.h:
  moved NOT_FIXED_DEC to the correct header
include/mysql_com.h:
  moved NOT_FIXED_DEC to the correct header
libmysql/libmysql.c:
  moved NOT_FIXED_DEC to the correct header
sql/field.h:
  moved NOT_FIXED_DEC to the correct header
sql/sql_string.h:
  moved NOT_FIXED_DEC to the correct header
storage/ndb/include/kernel/signaldata/DictTabInfo.hpp:
  moved NOT_FIXED_DEC to the correct header

Add result file format v2

Backport to 5.6.0   

Backport to 5.5: adjusted the test outputs in the funcs_1 test suite

Add support for being prompted for new passwords by mysqladmin instead of
specifying them on the command line. (Bug #5724, patch by Harrison Fisk)

(From: gkodinov)
Use and int * where possible to scan for trailing space in a
string instead of always iterating char-by-char.
Using the attached benchmark file on a 32 bit Intel Core 2 
Duo CPU I've got 43485 ms run with the fix compared to 44373 
without it.

Backported to 5.6.0 (next-mr-runtime)
6.0-codebase revid: 2476.1362.1

   Although the MY_SYNC_DIR flag supported in my_create(), my_delete(),
   my_rename() and my_symlink(), this feature is not used in the
   mysql code now. So technically we can declare the MY_SYNC_DIR as 0,
   but I decided to assign a new value for it as it's probably safer and
   worths nothing.

per-file comments:
  include/my_sys.h
Bug#47126      equal flag values causing unexpected behaviour
     assign unique value for the MY_SYNC_DIR

is invalid to preporcessor conditionals. Instead use
the autoconf generated macro to test the presence.

  In fact this crashes in normal (not embedded) run also.
  The problem is in the memory mapping. Handling the ha_myisammrg::extra(MMAP)
  the MERGE engine tries to mmap all the tables it unites.
  Though some can be empty and then in the mi_dynmap_file()
  we call the my_mmap(0). Normally this call returns MAP_FAILED,
  but not on FreeBSD. There it returns like a 'normal' value,
  and after the consequitive munmap systems gets unstable and
  crashes on some system call later.

per-file comments:
  storage/myisam/mi_dynrec.c
Bug #47139      Test "merge" crashes in "embedded" run
    don't try to mmap zero-length area, just return at once.

   The additional patch. That 'loadxml.test' failure was actually about our testing system,
   not the code.
   Firstly we need a new mysqltest command, wich i called 'send_eval'. So the expression
   can be evaluated, then started in a parallel thread. We only have separane 'send' and
   'eval' commands at the moment.
   Then we need to add the waiting code after the 'KILL' to our test, so the thread will be killed
   before the test goes further. The present 'reap' command doesn't handle the killed threads
   well.
      
per-file comments:

Bug#42520      killing load .. infile Assertion failed: ! is_set(), file .\sql_error.cc, line 8
    The 'send_eval' command implemented.

   test case added.

  Bug#27249 table_wild with alias: select t1.* as something

  Aliases to table wildcards are silently ignored, but they should
  not be allowed as it is non-standard and currently useless. There
  is not point in having a alias to a wildcard of column names.

  The solution is to rewrite the select_item rule so that aliases
  for table wildcards are not accepted.

  Bug#15192 "fatal errors" are caught by handlers in stored procedures

  The problem is that fatal errors (e.g.: out of memory) were being
  caught by stored procedure exception handlers which could cause
  the execution to not be stopped due to a continue handler.

  The solution is to not call any exception handler if the error is
  fatal and send the fatal error to the client.

  Bug#41860: Without Windows named pipe

  The problem was that the patch for Bug#10374 broke named pipe
  and shared memory transports on Windows due to a failure to
  implement a dummy poll method for transports other than BSD
  sockets. Another problem was that mysqltest lacked support
  for named pipe and shared memory connections, which lead to
  misleading test cases that were supposed run common queries
  over both transports.

  The solution is to properly implement, at the VIO layer, the
  poll and is_connected methods. The is_connected method is
  implemented for every suppported transport and the poll one
  only where it makes sense. Furthermore, support for named pipe
  and shared memory connections is added to mysqltest as to
  enable testing of both transports using the test suite.

client/mysqltest.cc:
  Add support for named pipe and shared memory connections.
include/violite.h:
  Move private functions to vio/vio_priv.h
  Add poll_read and is_connected methods.
mysql-test/t/named_pipe.test:
  Run tests over a named pipe connection.
mysql-test/t/shm.test:
  Run tests over a shared memory connection.
sql/item_func.cc:
  Rename method.
sql/sql_class.cc:
  Remove higher-level vio_is_connected implementation.
sql/sql_class.h:
  Rename vio_is_connected to not conflict with the vio one.
  Verify that there is a valid vio.
vio/vio.c:
  Add poll_read and is_connected methods.
vio/vio_priv.h:
  Add private functions.
vio/viosocket.c:
  Implement the is_connected method for the various transports.
