group-name symbols and obarrays

group-name symbols and obarrays

[Ken Raeburn]

Is there a reason why functions like gnus-group-list-groups and
gnus-group-insert-group-line intern the group names in the default
obarray instead of using one of the gnus hash tables?  After I quit
gnus, the primary obarray has lots of entries that are obviously group
names, though not all of the group names are included there.

Lots of gnus menu entry strings clutter the obarray too, and I have
menus disabled using menu-bar-mode in my .emacs file.

No.  So in September 0.14 they're all interned in
`gnus-active-hashtb', which is a hash table where most the group name
symbols already exists, so this should be a majorish improvement.  If
you list 5000 groups, you would get 5000 new symbols interned in
September 0.12.

Yup.  The menus are created even when `menu-bar-mode' is nil, which is
a bug, I guess.  Fix in 0.15.  But that means that the menus won't
appear as advertised if the user toggles `menu-bar-mode' a lot...
