While there still might be other bugs lurking in the specpdl code, this is cetainly a Good Thing to apply. Ben, I can make a ChangeLog entry, add a comment and apply this if you like. Gunnar

Ben, please finally get it into your head that the issues surrounding path searching are *hard*, and there are very few changes that you can make which won't screw some of the users. At least give someone else the benefit of the expertise here, come by the hard way. As for the *if*: I've gotten bashed plenty for the stat count path searching incurs. This would bump it up forther.

Ben Wing <ben(a)666.com> writes: > A red flag should have gone off in all of you guy's minds upon > encountering x-* in a generic function. Please fix. The set-face-stipple thing is mere FSF compatibility junk. As such, it should probably go to obsolete.el, except that it's not obsolete, only FSF-compatible. Since FSF uses x-bitmap-file-path, it would make little sense for an FSF-compatible function to use something else.

And, except for the package installation tools, it's far from all over the place. I'm pretty sure many users aren't aware of the possibility or use of a `~/.xemacs/'.

Broken native sound on Solaris 2.7 24 years

Raymond Toy

I always use NAS on my Solaris 2.7 box so I haven't noticed this before[1]. Assume you're running NAS ok. Kill the NAS server. XEmacs will gracefully revert to native sound. This used to work. However, now play any sound out and it comes out way too fast. (If the NAS server is restarted, XEmacs will start using the NAS server again.) I traced this down to the fact that even if the device status matches the file header, we need to set the device config (see init_device in sunplay.c). This only needs to be done once. A proposed patch is below. However, I wanted to know if it's kosher (for dumping, etc.) to initialize a static variable (initialized_device_p), as done in the patch. If not, can someone tell me what needs to be done? Alternatively, we can always set the device config from the file header instead of skipping it as is currently done in the code. This might be the easiest solution. With this patch, xemacs will continue to play sounds out correctly (the volume might be off) after the NAS server is killed. Thanks, Ray Footnotes: [1] Well, I recall sending out a message a long time ago about this, but didn't do anything about it.

(no subject) 24 years

James Risbey

Dear Xemacs Folk, I read your description of the differences between Xemacs and GNU Emacs and the reply of Richard Stallman on the same web page. I read your description as a catalog of technical issues. I read Stallman's as a request for legal papers in accord with the GPL. At the risk of stating the obvious, to say you diverge on technical issues seems to miss the point of Stallman's request. He does not question the technical choices you make, but asks only that you provide legal papers in accord with the GPL. Why don't you respond on that issue in the discussion on your web page? I would like to hear your views on that. James Risbey -- -----------------

Argh. ATHENA_INCLUDE strikes *again* 24 years

Valdis Kl=?iso8859-4?Q?=BA?=tnieks

OK, once we figured out that the AIX include scheme needed a simple include, and not the double-redirection that didn't work, ATHENA_INCLUDE started working fine. Now somebody made a '#define ATHENA_INCLUDE(a,b) SIMPLE_INCLUDE(a,b)', which trips over the same AIX preprocessor bug that STARTED this whole discussion. To sum up: Under AIX, '#define ATHENA_INCLUDE(a,b) <a/b>' works. Redirecting it any deeper through multiple #defines doesn't work. Yes, it's broken. Yes, there's a bug report open at IBM about it. I've appended the fix that I used to work around this - it's Ugly And Wrong, but got me a build... /Valdis *** lwlib/config.h.in.dist Mon Apr 3 16:16:37 2000 --- lwlib/config.h.in Mon Apr 3 16:19:16 2000 *************** *** 32,38 **** --- 32,42 ---- /* The path to the Athena widgets - the usual value is `X11/Xaw' */ #undef ATHENA_H_PATH #ifdef ATHENA_H_PATH + #if defined(_AIX) && !defined( __GNUC__) + # define ATHENA_INCLUDE(file) <ATHENA_H_PATH/file> + #else # define ATHENA_INCLUDE(file) SMART_INCLUDE (ATHENA_H_PATH,file) + #endif #else # define ATHENA_INCLUDE(file) <file> #endif
