Bug #1445	Windows servers: The Unkept Promise

Description:
Database directory symlinking on Windows is supported
only by the -max servers, mysqld-max and mysql-max-nt.
However, all the Windows servers seem to promise this
capability, because they uniformly respond YES to the
query SHOW VARIABLES LIKE 'have_symlink'.

For mysqld and mysqld-nt, this amounts to a promise
that is not kept, because they don't really process symlinks
properly.  The symlinked database shows up in the output
of SHOW DATABASES, but both USE db_name and SHOW
TABLES FROM db_name fail.

I would guess for mysqld and mysqld-nt, the value for
have_symlink should be NO?

How to repeat:
Symlink a database directory, then start either mysqld
or mysqld-nt.  Then try to use the database with USE
db_name or SHOW TABLES FROM db_name.

Forgot to fill in OS field.

Paul, this was fixed in some releases early, so the VC++ project
files has missed the sets for to enable the symlink for all the
servers. I am assigned Greg for to enable it again for the 
all VC++ projects files.

Sorry I forgot to mark verified.

Miiguel, does this mean that all Windows servers then
should support database symlinking, not just the -max
servers?

Yes Paul all the servers besides the -max ones, as I said before this
was already introduced and missed for unknown reason.

Thank you for your bug report. This issue has been committed to our
