Hm, defunct, eh?
The luatex binary itself definitely does not call uname as a
process, therefore this has to be the os.resultof() function
that Hans implements in l-os.lua. I am suspecting issues with
redirection now, as that function is defined as:
function os.resultof(command)
local handle = io.popen(command,"r")
return handle and handle:read("*all") or ""
end
The version in the garden has:
function os.resultof(command)
ioflush() -- else messed up logging
local handle = io.popen(command,"r")
if not handle then
-- print("unknown command '".. command .. "' in os.resultof")
return ""
else
return handle:read("*all") or ""
end
end
and it is called like so:
os.resultof('uname -m')
of course this will fail/block rather horribly if uname -m
does not write to STDOUT (and that is not just uname, thre
are a few more uses of os.resultof()).
I tried to redirect stdout and stderr to my log file, maybe that's a
problem then?
If I call using os.system, I can't redirect, but the result is the same.
I can redirect uname's output like so:
uname -m >> context.log
So I guess, it's using stdout at least normally - perhaps not via
os.resultof, no clue.
I just don't understand why any lua script would call uname externally
if it's available as os.uname?
Or does os.uname call os.resultof('uname')? (Probably not, otherwise
Florian's suggestion wouldn't have worked.)
print(os.resultof('uname -m'))
gives
attempt to call field 'resultof' (a nil value)
Can I import that function anyhow? I just copied it to my script and
replaced ioflush with io.flush.
My script now calls first os.uname and then the external one.
From the shell it works like expected.
And even from the server process! That alone doesn't seem to be the
problem.
