In retrospect, it might be better to have it default to "0" instead of the gnuserv (or even the parent XEmacs) PID. That way nothing breaks for users of only one gnuserv.

Forgot to give the patch for fixing the prototype... add this change.

You minimally need something else like: if (!hostarg) hostarg = getenv("HOST"); After the one-line change below. (It might be better to use gethostname(2) ). With that above change, your patch works for me (but see mine, below). > > any) of this suggestion, but it seems likely that mangling the UID + > > some user-specified number would be a nice way to provide this > > capability in a fairly clean way. > > There already is a UID in the name of the directory where the named > pipe resides.

This would be nice, but not quite perfect as figuring out the PID of the gnuserv processes is more troublesome than it needs to be (imagine the script that starts the XEmacs running the gnus-process). I've a slightly different approach that uses $GNUSERV_ID if that's in the environment instead of the PID. See patches below. With them, I can do: GNUSERV_ID=0 xemacs -f gnus & GNUSERV_ID=1 xemacs dissertation.tex & # my .emacs does gnuserv-start and then: gnuclient -P 0 -nw # connects to the XEmacs w/ gnus running gnuclient -P 1 -nw # connects to the XEmacs w/ dissertation.tex Note that I use numbers instead of an arbitrary string to avoid any possible issues with strange filenames, etc. My apologies for not patching the documentation.

Re: `scroll-up-command' still broken in 21.2 under AIX 24 years, 8 months

Markus Alt

It's not only that "Click on the scrollbar ..." problem, it's even not scrolling if I just press PgDown (`next' which runs `scroll-up-command'). Both has worked with 21.2.19. What's that gnuserv crash you were talking about? Is the keypress sequence really M-x # or did you mean C-x # ? In the latter case, this works fine for me.

I assume there aren't I think it was broken further back than that. I'm assuming you're referring to the "click on the scrollbar and it does a XGrabKeyboard and then scrolls all the way to the top"? I started looking into that one and couldn't see HOW the code differed for scroll down (which works) and scroll up (which doesnt).... In any case, it's still there as of -b31. There's also a crash relating to gnuserv closing a window when you use M-x #, but I've not gotten into chasing that one down yet... /Valdis

There already is a UID in the name of the directory where the named pipe resides. I intend to allow a second name pipe in that dir that depends on the Emacs PID.

Gutters break mouse based scrolling. 24 years, 8 months

Jan Vroonhof

I'm using 21.2.31 to do some real work today and this has been annoying me a bit. Take a large buffer Goto (point-max) Start selecting a region with the mouse (i.e. drag button-1). When you leave the window to hit the gutter, nothing happens. Continue until mouse is over the toolbar. Then scrolling starts. This is probably another remnant of the frame gutter is part of the window problem. Jan

Buffer tabs still flickering 24 years, 8 months

Hrvoje Niksic

The buffer tabs are still flickering when used with Gnus. Specifically, whenever I press SPC or DEL in the Summary buffer in order to scroll the current article by one page, the tabs flicker. Even if nothing really happen, as when I press DEL and I'm already at the beginning of the article. Is this a known bug that's supposed to be fixed, or does it happen only for me? P.S. Did I mention that it would be _really_ cool if the tabs could somehow respect the background pixmap? The gutter looks very ugly when the rest of the frame is pixmapized.
