Hello, after having checked out, built and tested cvs mcclim of two months, one months, 45 days, 37 days, and 41 days ago I've found the commit that has caused my CLX breakage: "Fix (temporary hack) to use file sockets in CLX on ACL": http://article.gmane.org/gmane.lisp.mcclim.cvs/418 The comment in this patch says: +;;; XXX CLX in ACL doesn't use local sockets, so here's a fix. This is gross +;;; and should obviously be included in Franz' clx and portable clx, but I +;;; believe that enough users will find that their X servers don't listen for +;;; TCP connections that it is worthwhile to include this code here +;;; temporarily. Of course, it would be nice to not require the X server to run without "--nolisten tcp" but this patch breaks the whole CLX (not only for mcclim) on my system. The function is obviously taken from Franz' version of clx (or both have a common ancestor) and then an if-construct is added that will, under certain circumstances, connect to the X server via the FILE menthod instead of the usual TCP connection. But in the version in acl/contrib/clx/dependent.cl this function is prefixed by an #+(and excl clx-use-allegro-streams) while clx-use-allegro-streams is pushed on the *features* in the Makefile of clx *only on mswindows*. If there is no clx-use-allegro-streams a variant of the function will be taken that uses a file descriptor (see ftp://ftp.franz.com/pub/contrib/clx/dependent.cl). As the new version in mcclim/Backends/CLX/port.lisp is only prefixed by #+allegro it will also replace the latter function, and that is not very nice as the described problems occur. Btw. the "fix" will also not work on mswindows if host is either string= to "" or "unix" as Franz's documentation to make-socket says: "The value of the address-family keyword can't be :file on Windows because Windows does not support it." (See http://www.franz.com/support/documentation/6.2/doc/pages/operators/socket/ma... or http://www.franz.com/support/documentation/8.0/doc/operators/socket/make-soc...) In general it is also all but nice that a function of the package xlib will be changed in the mcclim backend via a (defun xlib::open-x-stream ...). Because of these problems I propose to remove the patch from the mcclim cvs repository again. It would be nice to not require an X server that listens for TCP connections but this code is too buggy and mcclim/Backends/CLX/port.lisp is just not the right place for such an hack. What do you think?
