added skip-ndbcluster switch

after the previous run had some failures, provided it did not totally crash.

Change string->float conversion to delay division as long as possible.
This gives us more exact integer->float conversion for numbers of type '123.45E+02' (Bug #7740)

 - the variable MASTER_MY_PORT1 was used from the script, but it was not set to the port where the second server was started

After merge fixes
Don't give duplicate warnings for some ::store() functions

which fixes running the tests when using the bundled zlib.

  fixed start-and-exit flag

  USE_RUNNING_SERVER should be set to 0 or 1

we store 7 bytes (1 + 2*3) in every Query_log_event.
In the future if users want binlog optimized for small size and less safe,
we could add --binlog-no-charset (and binlog-no-sql-mode etc): charset info
is something by design optional (even if for now we don't offer possibility to disable it):
it's not a binlog format change.
We try to reduce the number of get_charset() calls in the slave SQL thread to a minimum
by caching the charset read from the previous event (which will often be equal to the one of the current event).
We don't use SET ONE_SHOT for charset-aware repl (we still do for timezones, will be fixed later).
No more errors if one changes the global value of charset vars on master or slave
(as we log charset info in all Query_log_event).
Not fixing Load_log_event as it will be rewritten soon by Dmitri.
Testing how mysqlbinlog behaves in rpl_charset.test.
mysqlbinlog needs to know where charset file is (to be able to convert a charset number found
in binlog (e.g. in User_var_log_event) to a charset name); mysql-test-run needs to pass
the correct value for this option to mysqlbinlog.
Many result udpates (adding charset info into every event shifts log_pos in SHOW BINLOG EVENTS).
Roughly the same job is to be done for timezones :)

  Old Solaris 'test' lack -e

  Added preparation of mysql_client_test(_embedded) and mysqltest(_embedded)
  Added --purify, --purecov, --quantify and --cxxfilt <cxxfiltprog> options
mysql-test-run.sh:
  Report correctly combinations of embedded+ps-protocol etc
  Added initial Purify support

  
  Test cases using common object (database,user,table,..) names could probably
  destroy customer data, when connecting to an already running server.
  
  This Changeset contains an auxiliary routine  include/testdb_only.inc" which
  should be sourced by tests doing such dangerous things. 
  The test case will get a "[skipped]" when the environment variable 
  USE_RUNNING_SERVER is not 0 .
  The modified mysql-test-run.sh sets USE_RUNNING_SERVER to 0, when 
  the "mysql-test-run" starts its own server, aka there was no "--extern"
  option.

    changed ndb_restore test somewhat to fisrt make the tables in myisam

  Let MYSQL_CLIENT_TEST be set with command line from mysql-test-run script
mysql-test-run.sh:
  Renamed client_test to mysql_client_test
  Support --embedded-server test on installed server
mysql_client_test.test:
  Renamed client_test to mysql_client_test
  Use env var CLIENT_TEST with full name, it differs when run with --embedded-server
  Rename: mysql-test/t/client_test.test -> mysql-test/t/mysql_client_test.test

  added ndb_restore test
ndb_restore.result, ndb_restore.test:
  new file

  backported access to ndb_mgm from 5.0

fix as not to overwrite previoulsy set flags in configure

  skip ndbcluster start failure if --force given

    added testcase for Bug#8035
    added option to wait for not-started
    Bug#8035

    report test mode if case of failure (default/ps-protocol/embedded)

    Install varchar.frm
    Otherwise type_varchar fails when running mysql-test-run on installed system
mysql-test/mysql-test-run.sh
    Use correct path to clist_tests in on installed system

  Removed references to ISAM and MERGE

from the install directory.

storage engine.

  removed diskless option for ndb test

First commit to mysql-5.0 tree to include MySQL Federated Storage Handler. This includes both the source and header files, test (results, test, require), and modifications to server and handler base files, and autoconf modifications to properly build federated handler.
