Yes -

Anyone have any other favorite variables which should just go?


ummm....global server variables only or also session server variables and
status variables?

old-passwords should die, as should the PASSWORD() function, now that auth
is not done in the MySQL server itself.  Even if someone writes a plugin for
MySQL to use a table for auth, folks shouldn't use PASSWORD().

obviously:  named pipe, socket, shared memory (and shared_memory_base_name),
which may already be out but I figured they might not be yet...same with
sql-mode.....log_bin_trust_function_creators deals with stored routines (sp,
sfunc and triggers)

The SSL_ variables should go; that should be made a plugin.

"new" and "old"  (I can't make this stuff up, folks....speaking of which I
found a variable called "one_shot" in the 6.0 docs, but there was no
description of what it did, so I filed
http://bugs.mysql.com/bug.php?id=38708)

last_insert_id could go -- it causes more problems than it solves IMO.  This
will likely be controversial...

lower_case_file_system
lower_case_table_names (just make 'em all case insensitive!)

system_time_zone -- unless it's such a huge win caching that...but when the
server changes time zones MySQL needs to restart.  pain!

I forget what was talked about for the character set/collation stuff, but
there are tons of variables for the
server/system/database/table/client/whatever charset and collation, that I'd
love to see whittled down or gone away for something more sane.

How often do folks set "flush" to "yes" (and flush_time)?  That's a loser in
my book, but kind of obscure and seems that it might be REALLY needed when
needed...but...

Why is there a "license" variable?  I mean, seriously.  I can understand the
version one (though the "version-comment" drives me batty!  it's either part
of the version or not!)
