tables".
Attempting to issue an INSERT DELAYED statement for a MERGE
table might have caused a deadlock if it happened as part of
a transaction or under LOCK TABLES, and there was a concurrent
DDL or LOCK TABLES ... WRITE statement which tried to lock one
of its underlying tables.
The problem occurred when a delayed insert handler thread tried
to open a MERGE table and discovered that to do this it had also
to open all underlying tables and hence acquire metadata
locks on them. Since metadata locks on the underlying tables were
not pre-acquired by the connection thread executing INSERT DELAYED,
attempts to do so might lead to waiting. In this case the
connection thread had to wait for the delayed insert thread.
If the thread which was preventing the lock on the underlying table
from being acquired had to wait for the connection thread (due to
this or other metadata locks), a deadlock occurred.
This deadlock was not detected by the MDL deadlock detector since
waiting for the handler thread by the connection thread is not
represented in the wait-for graph.
This patch solves the problem by ensuring that the delayed
insert handler thread never tries to open underlying tables
of a MERGE table. Instead open_tables() is aborted right after
the parent table is opened and a ER_DELAYED_NOT_SUPPORTED
error is emitted (which is passed to the connection thread and
ultimately to the user).
The crash during boot was caused by a DBUG_PRINT statement in fill_schema_schemata() (in
sql_show.cc). This DBUG_PRINT statement contained several instances of %s in the format
string and for one of these we gave a NULL pointer as the argument. This caused the
call to vsnprintf() to crash when running on Solaris.
The fix for this problem is to replace the call to vsnprintf() with my_vsnprintf()
which handles that a NULL pointer is passed as argumens for %s.
This patch also extends my_vsnprintf() to support %i in the format string.

Bug#56657: Test still uses "--exec rm -f ..." which is non-portable
Bug#56601: Test uses Unix path for temporary file, fails, and writes misleading message
Several tests that was written in a non portable way (failed on windows)
Fixed by
1) backporting the fix for replace_result to also apply to list_files
(mysqltest from mysql-trunk)
2) replacing all #p#/#sp#/#tmp# to #P#/#SP#/#TMP#/
(innodb always converts filenames to lower case in windows).
3) replacing '--exec rm -f' with '--remove_files_wildcard'
4) replacing a perl snippet with '--write_file'

Added --force to the mysql_upgrade command in the test scripts,
so that the test output does not depends on whether other tests involving an
upgrade have been executed or not in the same test suite execution.
