List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: emacs-devel-bounces+ged-emacs-devel=m.gmane.org@gnu.org Original-Sender: "Emacs-devel" Xref: news.gmane.org gmane.emacs.devel:209296 Archived-At: This is a heads-up for a proposed incompatible change to a rarely-used Emacs function. In Bug#24892 I propose declaring Emacs's memory-limit function to be obsolete, and changing it to be a placeholder that returns 0 everywhere (instead of its current practice of returning 0 on some platforms and nonzero values on others). The memory-limit function has been returning misleading or wrong information for years and as far as I know doesn't see significant use. For details please see: http://bugs.gnu.org/24892#23 and please reply to 24892@debbugs.gnu.org.
