Problem: mysqlbinlog_base64 fails because the binlog contains
traces from previous test cases.
Fix: Make have_log_bin reset the master's binlog.


mysql-test/include/have_log_bin.inc:
  Made have_log_bin reset the master logs, so that no traces of
  earlier test cases are left.
mysql-test/t/mysqlbinlog_base64.test:
  Removed debug info from previous push to this test.

This is not a fix to the bug. I'm just pushing a change to the
test case that will produce debug info when the test fails next
time.


mysql-test/t/mysqlbinlog_base64.test:
  Temporarily augmenting the test with debug info in order to
  analyze BUG#38127.

Post-push fix. The previous patch did 'reset master' at the wrong place.


mysql-test/include/master-slave-reset.inc:
  reset master must be called *after* the tables have been dropped.
  The purpose of reset master is to get rid of 'drop table' from
  the slave's binlog.

Post-push fixes: forgot to commit an updated result file.


mysql-test/suite/rpl_ndb/r/rpl_ndb_log.result:
  Updated result file.

Post-push fixes: I forgot to include the new files
start_slave.inc and stop_slave.inc in the previuos push.


mysql-test/include/start_slave.inc:
  Added file.
  Purpose: start slave synchronously, waiting for the two
  threads to start.
mysql-test/include/stop_slave.inc:
  Added file.
  Purpose: stop slave synchronously, waiting for the two
  threads to stop.

Problem 1: tests often fail in pushbuild with a timeout when waiting
for the slave to start/stop/receive error.
Fix 1: Updated the wait_for_slave_* macros in the following way:
- The timeout is increased by a factor ten
- Refactored the macros so that wait_for_slave_param does the work for
the other macros.
Problem 2: Tests are often incorrectly written, lacking a
source include/wait_for_slave_to_[start|stop].inc.
Fix 2: Improved the chance to get it right by adding
include/start_slave.inc and include/stop_slave.inc, and updated tests
to use these.
Problem 3: The the built-in test language command
wait_for_slave_to_stop is a misnomer (does not wait for the slave io
thread) and does not give as much debug info in case of failure as
the otherwise equivalent macro
source include/wait_for_slave_sql_to_stop.inc
Fix 3: Replaced all calls to the built-in command by a call to the
macro.
Problem 4: Some, but not all, of the wait_for_slave_* macros had an
implicit connection slave. This made some tests confusing to read,
and made it more difficult to use the macro in circular replication
scenarios, where the connection named master needs to wait.
Fix 4: Removed the implicit connection slave from all
wait_for_slave_* macros, and updated tests to use an explicit
connection slave where necessary.
Problem 5: The macros wait_slave_status.inc and wait_show_pattern.inc
were unused. Moreover, using them is difficult and error-prone.
Fix 5: remove these macros.
Problem 6: log_bin_trust_function_creators_basic failed when running
tests because it assumed @@global.log_bin_trust_function_creators=1,
and some tests modified this variable without resetting it to its
original value.
Fix 6: All tests that use this variable have been updated so that
they reset the value at end of test.

Bug #37940    rpl_dual_pos_advance fails sporadically on pushbuild,fail wait_for_slave_to_stop
Bug #37941    rpl_flushlog_loop fails sporadically on pushbuild
  
Several tests fail when waiting for the slave to stop in what
appears to be timeouts caused by a timeout value set to low. 
This causes false failures when the servers are loaded.
  
In order to try to avoid false negatives, we increase the
timeout 10 times and also print some more information in the
event that the slave fails to stop when expected to.
  
We add a printout of the current processes running to be able
to see if any process have been executing for an unexpectedly
long time, and also print the binlog events at the position
indicated by SHOW SLAVE STATUS.


mysql-test/include/wait_for_slave_sql_to_stop.inc:
  - Increasing default timeout 10 times and allowing it to be configurable.
  - Adding printout of process list on failure.
  - Adding printout of binlog events on master that has not yet been applied,
    unless $keep_connection is true.

This is not a fix, it just disables the erroneous test cases.


mysql-test/t/disabled.def:
  Disabled a number of new tests that contain sleeps and that
  have not been checked for race conditions. At least some of
  them contain race conditions.

Problem: the test syncs slave by a 'wait_condition' waiting until
table t1 has 5000 rows. However, there is no guarantee that t1
makes it to the slave before the wait_condition.
Fix: sync_slave_with_master just after t1 was created.


mysql-test/suite/rpl/t/rpl_insert.test:
  Added sync_slave_with_master to ensure that table t1 is on
  slave before the slave executes wait_condition.

The file tree in mtr's vardir has changed so an old
hard-coded path in mysql-test/t/subselect.test didn't

positions changed. Fixed by removing binlog positions from
output, and also:
 - removed code not used to verify the tested property
 - added comments


mysql-test/suite/rpl/r/rpl_row_inexist_tbl.result:
  Updated result file.
mysql-test/suite/rpl/t/rpl_row_inexist_tbl-slave.opt:
  Removed option file: it's not needed any more.
mysql-test/suite/rpl/t/rpl_row_inexist_tbl.test:
  Improved the test in the following ways:
   - The table t2 was not used to verify the property to test,
  so t2 has been removed.
   - Now printing only the relevant column from SHOW SLAVE STATUS
   - Added comments.

Made the test innodb_max_dirty_pages_pct_func clean up after itself.


mysql-test/r/innodb_max_dirty_pages_pct_func.result:

Problem: rpl_ndb_transaction fails because it assumes nothing
is written to the binlog at a certain point. However, ndb may
binlog updates in ndb system tables at a nondeterministic
time point after an ndb table update has been committed.
Fix: break the test into two. rpl_ndb_transaction still does
the ndb updates needed by the first half of the test. The new
test case rpl_bug26395 includes the part that assumes nothing
more will be written to the binlog.


mysql-test/include/sync_slave_io_with_master.inc:
  Like sync_slave_with_master, but only waits until the IO thread has
  synced; the SQL thread may still be behind.
mysql-test/suite/rpl/r/rpl_bug26395.result:
  New result file.
mysql-test/suite/rpl/t/rpl_bug26395-master.opt:
  New option file.
mysql-test/suite/rpl/t/rpl_bug26395-slave.opt:
  New option file.
mysql-test/suite/rpl/t/rpl_bug26395.test:
  - Moved second half of rpl_ndb_transaction here.
  - Improved the test case: instead of using a sleep,
  it waits for the slave's io thread to sync up to a proper
  position, and for the slave's sql thread to sync up to
  another position.
  - Added a warning that no more tests should be added at the
  end of the file.
mysql-test/suite/rpl_ndb/r/rpl_ndb_mixed_engines_transactions.result:
  Updated and renamed result file.
mysql-test/suite/rpl_ndb/t/rpl_ndb_mixed_engines_transactions-master.opt:
  No need for the special debug flag any more, it was used by
  the second part of the test which is now in rpl_bug26395.
  Also renamed the file.
mysql-test/suite/rpl_ndb/t/rpl_ndb_mixed_engines_transactions-slave.opt:
  Renamed option file.
mysql-test/suite/rpl_ndb/t/rpl_ndb_mixed_engines_transactions.test:
  - Moved second half of the test to another test (rpl_bug26395)
  - Improved comments.
  - Extended the mixed transaction test to include also innodb.
  - Used 'source include/diff_tables.inc' instead of listing
  several identical tables in the result file.
  - Renamed the test.

Problem 1: main.loaddata tried to trigger an error caused by
reading files outside the vardir, by reading itself. However,
if loaddata.test is not world-readable (e.g., umask=0077),
then another error is triggered.
Fix 1: allow the other error too.
Problem 2: rpl_slave_skip and rpl_innodb_mixed_dml tried to
copy a file from mysql-test/suite/rpl/data to mysql-test/var
and then read it. That failed too if umask=0077, since the
file would not become world-readable.
Fix 2: move the files from mysql-test/suite/rpl/data to
mysql-test/std_data and update tests accordingly. Remove
the directory mysql-test/suite/rpl/data.


mysql-test/r/loaddata.result:
  Updated result file.

  Moved this file to std_data.
mysql-test/std_data/rpl_mixed.dat:

mysql-test/suite/rpl/data:
  Removed directory that is now unused.
mysql-test/suite/rpl/include/rpl_mixed_dml.inc:

mysql-test/suite/rpl/t/rpl_slave_skip.test:
  The rpl_bug28618.dat file has been moved. Updated the test
  to use the new location.
mysql-test/t/loaddata.test:
  Allow more error messages. ER_TEXTFILE_NOT_READABLE may
  happen if the file is not world-readable (which may happen,
  e.g., if the user has umask=0077).
