Description:
If you enable general log and slow query log in my.ini by

[mysqld]
log
log-slow-queries

there's no logging, neither in the file system (data directory), nor in the mysql.general_log and mysql.slow_log tables (which don't exist).

How to repeat:
see above

Suggested fix:
As with MySQL 5.1.7-beta with Linux, the general log and the slow query log should be stored in the mysql.general_log and mysql.slow_log tables.

I was able to repeat only on Windows even when started from the
shell prompt.

That's correct - just as Bug 17367, this is specific to Windows.

The csv storage engine which is needed to log to table is not in the windows version. It will have to be added.

This also causes the following failure of "event_slow_query" on windows.

events_slow_query              [ fail ]

Errors are (from C:/cygwin/home/mysqldev/pb/mysql-5.1-new/push-lars@mysql.com-20060301173527.info/mysql-5.1.8-beta-standard/mysql-test/var-n_stm-5/log/mysqltest-time) :

CSV storage engine is now enabled in Windows builds

Is there a way to log to a file? I truly believe that this should still be an option. I'm tracing queries against the database for testing DBD::mysql, and tailing the CSV file is less than desireable.

Also, only "Execute" is shown in the log, "Prepare" is still empty.

Patch was pushed to 5.1.10

Noted in 5.1.10 changelog.

Logging to the <literal>mysql.general_log</literal> and
<literal>mysql.slow_log</literal> tables did not work for
Windows builds because the <literal>CSV</literal> storage
engine was unavailable. The <literal>CSV</literal> engine now
is enabled in Windows builds. (Bug #17368)
