gnuclient: if TMPDIR was set and connect failed, try again with /tmp
2011-06-03 Aidan Kehoe <kehoea@parhasard.net>
* gnuslib.c (connect_to_unix_server):
Retry with /tmp as a directory in which to search for Unix sockets
if an attempt to connect with some other directory failed (which
may be because gnuclient and gnuserv don't share an environment
value for TMPDIR, or because gnuserv was compiled with USE_TMPDIR
turned off).

| 48 /* helper function to correctly open Xft/core fonts by name | |
| 49 #### Can't we use FcParseName here? | |
| 50 #### Is this done so often that the logic needs to be hard-coded in C? | |
| 51 | |
| 52 Daniel Pittman sez: Older code tried to enforce that an XLFD font was | |
| 53 not scaled, while this version just doesn't care. I think that is a | |
| 54 better behavior, since if someone really wants a scaled font we should | |
| 55 oblige them. | |
| 56 | |
| 57 Stephen sez: This whole function was ill-conceived, and I'm not sure it | |
| 58 succeeds at any of the things it attempts to do. First, we should be | |
| 59 using fontconfig directly. I'm not sure what Xft (or fontconfig) will | |
| 60 try to do if passed an XLFD. As for scaled fonts, both options are | |
| 61 equally bad. The problem is that the X server will often scale bitmap | |
| 62 fonts willy-nilly; it's worth trying to avoid that, but I can't say | |
| 63 whether that's worth overriding somebody who knows what they're doing. | |
| 64 In any case, I think we should find out what Xft (fontconfig?) is able | |
| 65 and willing to do with XLFDs, and probably move the logic to LISP. | |
