Description Toralf Förster gentoo-dev 2008-04-06 10:14:31 UTC
Wondering why that program ignored my lines in .Xdefaults:

tfoerste@n22 ~ $ grep ^XB .Xdefaults
XBoard*size:            Bulky
XBoard*geometry:         +0+0

I got the answer answer after I used strace:

read(3, "\1\0\n\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0<\26 \10\2005\223\277\2305\223\277", 32) = 32
uname({sys="Linux", node="n22", ...})   = 0
open("/home/tfoerste/.Xdefaults-n22", O_RDONLY) = -1 ENOENT (No such file or directory)

For some reason the program expects the hostname appended to .Xdefaults. But having a deeper look into the program it seems that it isn't able to read X11 resources, neither from .Xdefaults-n22 nor from ~/XBoard (content:

tfoerste@n22 ~ $ cat XBoard
XBoard*size:            Bulky
XBoard*geometry:         +0+0

) b/c strace shows :

access("/home/tfoerste/XBoard", R_OK)   = 0
stat64("/home/tfoerste/XBoard", {st_mode=S_IFREG|0644, st_size=61, ...}) = 0
open("/home/tfoerste/XBoard", O_RDONLY) = 4
fstat64(4, {st_mode=S_IFREG|0644, st_size=61, ...}) = 0
read(4, "XBoard*size:            Bulky\nXB"..., 61) = 61
close(4)                                = 0

I'm wondering why that program isn't able to read in the resource file. The program itself might be ancient old but the calls for open and read files should work even after years, isn't it ?

BTW the command line accept options so it isn't a big problem for me :)

Reproducible: Always

This is not specific to xboard.  I'm told the preferred name for that file changed from .Xdefaults to .Xresources long ago, and it seems the X libraries finally are looking only at .Xresources.

You can also put the lines in a file called XBoard.

The xboard man page should be updated, though.

Comment 4 Toralf Förster gentoo-dev 2008-04-06 18:57:33 UTC
The _real_ problem is that it doesn't even read those entries :

access("/home/tfoerste/XBoard", R_OK)   = 0
stat64("/home/tfoerste/XBoard", {st_mode=S_IFREG|0644, st_size=61, ...}) = 0
open("/home/tfoerste/XBoard", O_RDONLY) = 4
fstat64(4, {st_mode=S_IFREG|0644, st_size=61, ...}) = 0
read(4, "XBoard*size:            Bulky\nXB"..., 61) = 61    <-------wrong
close(4)                                = 0

The file consists of 2 lines but only the first line is read in and in addition the value even from the first line is not used :-(
Comment 5 Tim Mann 2008-04-08 16:48:55 UTC
Oops, sorry, I failed to read your initial bug report in full.  Stupid of me.

xboard (or more precisely, the Xt library that xboard is linked with) was reading the resource files in full, as the strace output shows.  When you say it's reading only the first line, that's incorrect -- you've misinterpreted the strace output.  The read system call read 61 bytes, which was the entire file.  strace showed a few bytes of that followed by "..." to indicate there was more.

The reason the "XBoard*size" resource didn't work for you is because there is no such resource.  The correct name of the resource is "XBoard*boardSize".  Please see the beginning of the OPTIONS section of the man page where it explains "For options that have two names, the longer one is the name of the corresponding X resource; the short name is not recognized."  The short name (-size in this case) works only as a command line option, not as a resource name.

I don't know why the geometry resource didn't work for you.  I tried the same thing on my Ubuntu 7.10 system with gnome desktop and it works for me.  Perhaps whatever window manager you're using is not respecting geometry requests from applications.

Arrgh, my fault -sry.
BTW thanks for the explanation of the strace behaviour. I wasn't aware of that.

I close this report.
