b626d5d78e BUG#17654 : --read-from-remote-server causes core
This patch corrects a problem encountered when reading the binlog from a remote
host. The application was crashing because the buffer variable (temp_buf) in 
log_event was not pointing to the incoming data. For a normal file read, this 
buffer is allocated by a previous call of read_log_event. However, when reading
from a remote host, the first call to read_log_event is not executed therefore
no buffer is allocated. Furthermore, there is no need to allocate a new buffer 
because the incoming stream is what needs to be read. 

This patch adds the call to initialize the temp_buf variable if reading from a 
remote host. It also adds a check at destroy time to ensure the temp_buf is not
freed if reading from a remote host.


client/mysqlbinlog.cc:
  BUG#17654 : --read-from-remote-server causes core
  
  This patch corrects a problem when reading from a remote host. The temp_buf 
  variable of the log_event class is undefined. This patch assigns the temp_buf
  variable to the address of the incoming stream. This allows the print functions
  to print the binlog events correctly.

f3b78f34e5 Bug#27507: Wrong DATETIME value was allowed by ALTER TABLE in the NO_ZERO_DATE
mode.

When a new DATE/DATETIME field without default value is being added by the
ALTER TABLE the '0000-00-00' value is used as the default one. But it wasn't
checked whether such value was allowed by the set sql mode. Due to this
'0000-00-00' values was allowed for DATE/DATETIME fields even in the
NO_ZERO_DATE mode.

Now the mysql_alter_table() function checks whether the '0000-00-00' value
is allowed for DATE/DATETIME fields by the set sql mode.
The new error_if_not_empty flag is used in the mysql_alter_table() function
to indicate that it should abort if the table being altered isn't empty.
The new new_datetime_field field is used in the mysql_alter_table() function
for error throwing purposes. 
The new error_if_not_empty parameter is added to the copy_data_between_tables()
function to indicate the it should return error if the source table isn't empty.

c367385f7f BUG#25659 - memory leak via "plugins" test
- Added suppressions for dlopen to make plugin test pass.
- Do not pass empty string to mysqld, since my_getopt is
  not capable to handle it.
- Re-enabled trailing UNINSTALL PLUGIN statement of plugin.test.

The memory leak described in the bug report happens in libdl, not
in mysqld. On some valgrind installations this error is suppressed
by default, no idea why it isn't suppressed on pb-valgrind.

<observation>
If library remains open after thread has finished, and is closed by
another thread, we get memory leak. But in case library is opened and
closed by the same thread no leak occurs.
</observation>


mysql-test/lib/mtr_io.pl:
  Do not pass empty string since my_getopt is not capable to handle it.
  This is required to make plugin.test work on platforms where
  ha_example is not compiled.
mysql-test/r/plugin.result:
  Updated test result.
mysql-test/t/plugin.test:
  Re-enabled UNINSTALL PLUGIN statement. It is a good idea to cleanup
  at the end of the test. Anyway bug22694 was fixed while this test
  was disabled.

1a60685cba Patch changing how ALTER TABLE implementation handles table locking
and invalidation in the most general case (non-temporary table and
not simple RENAME or ENABLE/DISABLE KEYS or partitioning command).

See comment for sql/sql_table.cc for more information.

These changes are prerequisite for 5.1 version of fix for bug #23667
"CREATE TABLE LIKE is not isolated from alteration by other connections"


mysql-test/include/mix1.inc:
  Extended coverage for behavior of ALTER TABLE statement under LOCK TABLES,
  which should be consistent across all platforms and for all engines.
mysql-test/r/alter_table-big.result:
  Changed test for bug #25044 to use @@debug and injected sleeps
  infrastructure. Extended test coverage for ALTER TABLE's behavior
  under concurrency.
mysql-test/r/alter_table.result:
  Extended coverage for behavior of ALTER TABLE statement under LOCK TABLES,
  which should be consistent across all platforms and for all engines.
mysql-test/r/innodb_mysql.result:
  Extended coverage for behavior of ALTER TABLE statement under LOCK TABLES,
  which should be consistent across all platforms and for all engines.
mysql-test/t/alter_table-big.test:
  Changed test for bug #25044 to use @@debug and injected sleeps
  infrastructure. Extended test coverage for ALTER TABLE's behavior
  under concurrency.
mysql-test/t/alter_table.test:
  Extended coverage for behavior of ALTER TABLE statement under LOCK TABLES,
  which should be consistent across all platforms and for all engines.
sql/mysql_priv.h:
  Made functions reopen_table() and close_handle_and_leave_table_as_lock()
  available outside of sql_base.cc file.
  Changed close_data_tables() in such way that after closing handler
  for the table it leaves TABLE object for it in table cache not as
  placeholder for ordinary name-lock but as placeholder for an exclusive
  name-lock. Renamed this routine to close_data_files_and_morph_locks().
sql/sql_base.cc:
  Made functions reopen_table() and close_handle_and_leave_table_as_lock()
  available outside of sql_base.cc file.
  Changed close_data_tables() in such way that after closing handler
  for the table it leaves TABLE object for it in table cache not as
  placeholder for ordinary name-lock but as placeholder for an exclusive
  name-lock. Renamed this routine to close_data_files_and_morph_locks().
  Also adjusted it so it can work properly not only in LOCK TABLES mode.
sql/sql_table.cc:
  Changed the way in which ALTER TABLE implementation handles table
  locking and invalidation in the most general case (non-temporary table
  and not simple RENAME or ENABLE/DISABLE KEYS or partitioning command)
  
  Now after preparing new version of the table we:
  1) Wait until all other threads close old version of table.
  2) Close instances of table open by this thread and replace them
     with exclusive name-locks.
  3) Rename the old table to a temp name, rename the new one to the
     old name.
  4) If we are under LOCK TABLES and don't do ALTER TABLE ... RENAME
     we reopen new version of table.
  5) Write statement to the binary log.
  6) If we are under LOCK TABLES and do ALTER TABLE ... RENAME we
     remove name-locks from list of open tables and table cache.
  7) If we are not not under LOCK TABLES we rely on close_thread_tables()
     call to remove name-locks from table cache and list of open table. 
  
  Such approach:
  a) Eliminates possibility for concurrent statement to sneak in and get
     access to the new version of the table before ALTER TABLE gets logged
     into binary log.
  b) Ensures that ALTER TABLE behaves under LOCK TABLES in the same way
     on all platforms and for all engines (in 5.0 this was not true) 
  c) Preserves nice invariant that if table is open in some connection
     there is a guarantee that .FRM file for this table exists and is
     properly named.
