The fact is, I'm not convinced that Scheme works reliably. The mmap-based relocating allocator is supposed to return memory to the system, but even so... I still think opening (and unzipping) a bunch of files is not to be dismissed lightly. I guess I'm in the minority. > [The devils advocate could argue at this point that you should > consider switching to a distro that has more frequent releases] Like Solaris? :-) I'd use just about anything else, but everyone around me uses Debian, so Debian it is. (And yes, they use potato too.)

The discussion you refer to was centered around an entirely different topic---we were arguing whether missing dir files should produce error messages. But you're right: If it were up to me, I'd dump the whole concept of dir files and caches and whatnot. My machine isn't especially fast by today's standards, and when I start up info, it pulls a gazillion info files from a distributed file system. I don't mind the startup cost (maybe 20 seconds) at all. I think the problem in Hrvoje's setup is really that all the info files are gzipped. Given today's price for disk space, I think unpacking them would be the easiest way to fix the problem. Stephen> If so, shouldn't the only cache we trust be one we make Stephen> ourselves? Sure, but in that case, let's abandon dir files entirely. -- Cheers =8-} Chipsy Friede, Völkerverständigung und überhaupt blabla

At compile time, with flat Xaw, we pick up /usr/X11R6/lib/libXaw.* -- but at runtime the ld.so.conf puts the Xam3d library as 'libXaw.so' in the path first. This can't be found through any method short of dynamic-linking of an executable at configure time and looking in the output on STDERR for the cursed `consider relinking' thing. The quick fix[1] is to edit /etc/ld.so.conf and move the entry for /usr/X11R6/lib/ before the entry for /usr/X11R6/lib/Xaw3d/. That will pick up the correct flat Athena. Building with `--with-athena=3d' will also work. I don't know if we /can/ do anything much about the issue otherwise. It's not actually fixable easily (thanks, Debian) as far as I can see. LD_PRELOADing the correct Athena library would also work.... Daniel Footnotes: [1] which makes everything else use flat Athena unfortunately -- There are two major products that come out of Berkeley: LSD and UNIX. We don't believe this to be a coincidence. -- Jeremy S. Anderson

Re: 21.2 Out of sync: window-minibuffer-p arg is optional in Emacs 25 years, 10 months

posting-list(a)mailandnews.com (Jari Aalto+mail.emacs) writes: > This is just my opinion, but if function starts with argument BUFFER > ot WINDOW or FRAME, they all should be optional and by default refer > to current (active) unit. An argument should be optional only if it makes sense for it to be optional. For instance, functions used in loops like `window-next-child' or `window-parent' almost never want to deal with selected window. Also, doesn't add much value for `window-live-p' to default to selected window, since the selected window will always be live. I'll update window-minibuffer-p for the sake of compatibility, but I won't touch other functions.

Look for the highlighted words. Fortunately, my patch was followed by a *second* patch, which when applied after the first one DOES fix that crash (or so it should.)

report_extent_modification() crash (hopefully) fixed 25 years, 10 months

Hrvoje Niksic

I think the report_extent_modification() crash should be fixed in current CVS. Please try it and let me know. One crash recipe is available at <http://www.xemacs.org/cgi-bin/wilma_hiliter/xemacs-beta/199912/msg00323.html>.

I get it repeatedly. The best way to repeat it is by going somewhere deep into Info hierarchy, and then press `u' repeatedly to return to `dir'.

I thought the idea was that such a directory was strictly optional. I, for one, don't have one.
