unknown 0541dcad3b Bug#24404: strange bug with view+permission+prepared statement.
The problem was that if a prepared statement accessed a view, the
access to the tables listed in the query after that view was done in
the security context of the view.

The bug was in the assigning of the security context to the tables
belonging to a view: we traversed the list of all query tables
instead.  It didn't show up in the normal (non-prepared) statements
because of the different order of the steps of checking privileges
and descending into a view for normal and prepared statements.

The solution is to traverse the list and stop once the last table
belonging to the view was processed.


mysql-test/r/view_grant.result:
  Add result for bug#24404: strange bug with view+permission+prepared
  statement.
mysql-test/t/view_grant.test:
  Add test case for bug#24404: strange bug with view+permission+prepared
  statement.
sql/sql_view.cc:
  Remove dead line.
  When setting security context, we should traverse the list of tables
  belonging to a given view, not all query tables.  We achieve that by
  stopping at the first table past view_tables_tail.

This directory contains a test suite for the MySQL daemon. To run
the currently existing test cases, simply execute ./mysql-test-run in
this directory. It will fire up the newly built mysqld and test it.

Note that you do not have to have to do "make install", and you could
actually have a co-existing MySQL installation. The tests will not
conflict with it.

All tests must pass. If one or more of them fail on your system, please
read the following manual section for instructions on how to report the
problem:

http://dev.mysql.com/doc/mysql/en/mysql-test-suite.html

If you want to use an already running MySQL server for specific tests,
use the --extern option to mysql-test-run. Please note that in this mode,
the test suite expects you to provide the names of the tests to run.
For example, here is the command to run the "alias" and "analyze" tests
with an external server:

mysql-test-run --extern alias analyze

To match your setup, you might also need to provide --socket, --user, and
other relevant options.

With no test cases named on the command line, mysql-test-run falls back
to the normal "non-extern" behavior. The reason for this is that some
tests cannot run with an external server.


You can create your own test cases. To create a test case, create a new
file in the t subdirectory using a text editor. The file should have a .test
extension. For example:

 xemacs t/test_case_name.test

 In the file, put a set of SQL statements that create some tables,
 load test data, and run some queries to manipulate it.

 We would appreciate it if you name your test tables t1, t2, t3 ... (to not
 conflict too much with existing tables).

 Your test should begin by dropping the tables you are going to create and
 end by dropping them again.  This ensures that you can run the test over
 and over again.
 
 If you are using mysqltest commands (like result file names) in your
 test case, you should create the result file as follows:

 mysql-test-run --record test_case_name

 or

 mysqltest --record < t/test_case_name.test

 If you only have a simple test cases consisting of SQL statements and
 comments, you can create the test case in one of the following ways:

 mysql-test-run --record test_case_name

 mysql test < t/test_case_name.test > r/test_case_name.result

 mysqltest --record --record-file=r/test_case_name.result < t/test_case_name.test

 When this is done, take a look at r/test_case_name.result
 - If the result is incorrect, you have found a bug. In this case, you should
   edit the test result to the correct results so that we can verify
   that the bug is corrected in future releases.

To submit your test case, put your .test file and .result file(s) into
a tar.gz archive, add a README that explains the problem, ftp the 
archive to ftp://support.mysql.com/pub/mysql/secret/ and send a mail
to bugs@lists.mysql.com
