Subject: Reachable killed buffers [Was: Re: [Emacs-diffs] /srv/bzr/emacs/trunk r109890: Do not mark objects from deleted buffers, windows and frames]
Date: Mon, 10 Sep 2012 13:46:05 +0400 [thread overview]
Message-ID: <504DB6DD.9030002@yandex.ru> (raw)
In-Reply-To: <5049C400.8070400@gmx.at>
I found two places where the killed buffer may survive for a while
and so create some unneeded pressure to GC:
1) 'where' slot of Lisp_Buffer_Local_Value, which has local_if_set 0.
When the buffer is killed, swap_out_buffer_local_variables can't see
this BLV's symbol because it's not in buffer's local_var_alist.
Shouldn't we call to swap_in_global_binding for such an "orphaned" BLVs?
2) 'prev_buffers' and 'next_buffers' of struct window. When the buffer
is killed, replace_buffer_in_windows should remove it from these lists;
but window-list-1 returns only live windows, so we may end up with
dead window with a long list of killed buffers referenced from prev_buffers
and/or next_buffers.
