XEmacs' desktop icon greyed out - revisited 24 years, 9 months

ALTMARK＠de.ibm.com

Hm, looks like XEmacs doesn't care too much about what visual I want him to use (at least on my graphic card!): altmark＠pdw7: */altmark (1) $ ~/rs_aix43/xemacs/bin/xemacs -visual PseudoColor8 -vanilla Invalid Visual specification in PseudoColor8... ignoring. altmark＠pdw7: */altmark (2) $ ~/rs_aix43/xemacs/bin/xemacs -visual TrueColor24 -vanilla Invalid Visual specification in TrueColor24... ignoring. altmark＠pdw7: */altmark (3) $ ~/rs_aix43/xemacs/bin/xemacs -visual DirectColor24 -vanilla Invalid Visual specification in DirectColor24... ignoring. Needless to say that it starts up with the grey icon at each of these tries. To debugging device-x.c: It decides on TrueColor (visual class 4) with depth 24. Why? x_try_best_visual returns to its caller after successfully trying for TrueColor and a depth >= 16 in the very first if-expression. Within x_try_best_visual_class, the XGetVisualInfo function call assigns a structure to vi_out[0] which has depth=24 and class=4 (TrueColor) field values and will be selected as best visual by the following for-loop. So this visual is what x_try_best_visual_class returns to x_try_best_visual. x_get_visual_depth finds depth 24. I don't know if this is exactly what you wanted, but I gladly provide any further information if necessary.

Valdis, I'm also curious about the new GXT300P (although I must say that I don't too much hope considering the latest experiences with the other cards). We might get some boxes with those cards in 2Q2000 and of course this will be the first thing I'll try on them then! I'll keep you posted. Markus

Using the old configure option --with-session (or new --with-wmcommand) means that DEVICE_X_WM_COMMAND_FRAME is not set. This is default in 21.1/21.2.

[web] multilingual web service 24 years, 9 months

Kazuyuki IENAGA

I've noticed that www.xemacs.org has Japanese contents as "/Languages/Japanese/index.html". The host www.xemacs.org is running Apache/1.3.3. So how about to use ``MultiView'' option of Apache? For what about MultiView, see the document of "mod_negotiation". (http://www.apache.org/docs/mod/mod_negotiation.html) There's some sites using it. For example, www.debian.org is one of them. To use or not to use, to be worth or not, I'd like to hear how do you think about it. When I have spare time (after 15 Feb.) and if you agree, I wish to setup some corner of www.xemacs.org to test MultiView. -- kazz

CVS read lock file removed. 24 years, 9 months

Re: [PATCH] fix for Crash in mapcar1 .... 24 years, 9 months

Vin Shelton

OK, I'm confused again. The enclosed patch won't apply at all to 21.1. Kyle, is there a similar patch you want to apply for 21.1? I can't grok what's supposed to be going on from the limited context in the patch.

Oops. I just found the next thread which Martin started about mapcar1. I will go ahead an apply Kyle's patch for 21.1.9, unless there are any objections. - vin

Unfortunately the patch tracking is currently done using a wetware implemenation that is overloaded with other stuff. This really should be automated, but until then I do it by hand. I am fairly sure we haven't missed any patches by non-XEmacs people. However I do make mistakes (especially when I do this at 3:15am after a full day of bounding Feynman graphs). Somehow my own stuff falls through the cracks more often :-(.. I have only recently made a summary for xemacs-review for the first time. I'll forward it here.. Jan
