Fix Bug#21704 Renaming column does not update FK definition
by checking whether a column that participates in a FK definition is being
renamed and denying the ALTER in this case.
The patch was originally developed by Davi Arnaut <Davi.Arnaut@Sun.COM>:
http://lists.mysql.com/commits/77714
and was later adjusted to conform to InnoDB coding style by me (Vasil),
I also added some more comments and moved the bug specific mysql-test to
a separate file to make it more manageable and flexible.
- Make a rough filtering of the servers error log and write
all suspicious warnings to $error_log.warnings
The .warnings file is then examined more carefully by check_warnings.test
- This will speed things up, doing all of this in a server running
under valgrind takes far too long time.
- rewrite "check warnings" to be faster by not creating a full join
between error_log and suspicious_patterns while running REGEXP.
Instead add a column to error_log that will be set to 1 to indicate
a warning and run the 6 REGEXP's we have for suspicious lines as
6 separate full table scans.
- Remove the "suspicious_patterns" table from mtr db
- Use 'xykls37' as separator when loading the error log, that line should
hopefully never exist in a line that should be a warning
In mtr.check_warnings, `text` was declares as type text, which is
64K, and when the server log grows larger than this, it would be
truncated, and then check_warnings was actually checking the
error messages of a previous test and complain warnings.
This patch fixed the problem by change the type of `text` to
mediumtext, which is 16M.
mysqltest command 'shutdown_server' is supposed to shutdown the server
and wait for it to be gone, and kill it when timeout. But because the
arguments passed to my_kill were in the wrong order, 'shutdown_server'
does not wait nor kill the server at all. So after 'shutdown_server',
the server is still running, and the server may still accepting
connections.
Problem: during a refactoring of mtr, a pattern for suppressing a warning from lowercase_table3 was lost.
Fix: re-introduce the suppression.
Problem 2: suppression was misspelt as supression. Fixed by adding a p.
