When trying to run the falcon_bugs test like this:

./mysql-test-run --suite=falcon --mem --force falcon_bugs

using a MySQL that has been compiled without support for ucs2, the test fails with the following output:

mysqltest: At line 273: query 'CREATE TABLE t1 (a varchar(8)) DEFAULT CHARSET ucs2' failed: 1115: Unknown character set: 'ucs2'

The result from queries just before the failure was:

*** Bug #91 ***
SET @@storage_engine = Falcon;
create table t1 (C001 VARCHAR(1000) CHARACTER SET utf8, PRIMARY KEY (C001(255)));
*** Bug #122 ***
SET @@storage_engine = Falcon;
`id` int(10) unsigned NOT NULL,

KEY `f3` (`f3`)
DROP TABLE falcon;
*** Bug #115 ***
SET @@storage_engine = Falcon;
CREATE TABLE t1 (a varchar(8)) DEFAULT CHARSET ucs2;

How to repeat:
1. Compile MySQL with Falcon with the following configure command:

   ./configure --with-plugins=falcon,partition

2. Run the falcon_bugs test:

   ./mysql-test-run --suite=falcon falcon_bugs


Suggested fix:
The test should check/require that MySQL is compiled with support for ucs2.

Verified in latest mysql-6.0-falcon-team branch.
I'll fix it right away.

      Fix for Bug#41877 - falcon_bugs test fails if MySQL is compiled without ucs2 support.
      Added check for UCS2 support in falcon_bugs test.
[6 Jan 2009 9:13] John Embretsen
Olav, the fix I just committed will make sure the falcon_bugs test is skipped if UCS2 support is not compiled in:

TEST                           RESULT         TIME (ms)

falcon.falcon_bugs             [ skipped ]   Test requires: 'have_ucs2'

This looks OK to you?
[6 Jan 2009 10:20] Olav Sandstå
Patch looks correct. I have verified that before applying the patch the test will fail if run with a MySQL compiled without UCS2 support while after applying the patch the test will not get run.
