Package: foomatic-filters
Version: 4.0.5-6+squeeze1
Severity: important
When running lenny, I have been using foomatic-rip with lprng.
On upgrading to squeeze, foomatic-rip fails with the message:
process dying with "Cannot find a writable temp dir".
The error seems to be in function "temp_dir()" in source file "util.c",
The search for a temporary-file directory, encounters a
premature NULL pointer (from getenv) which terminates the search.
The undeclared variable "P_tmpdir" also seems to be a NULL pointer.
Also, in foomatic-filters_4.0.9 (from unstable), the declaration of
dirs lacks a terminating NULL.
I observe that this code is not used by the CUPS printing system,
but it is required by lprng. CUPS passes data to foomatic rip as
command-line arguments; lprng uses a pipe.
I don't know how to make patches properly (I apologise),
so I'll just put my code for temp_dir() here.
It works when I test it.
---------------------------------
const char * temp_dir()
{
static const char *tmpdir = NULL;
if (!tmpdir)
{
/*
* getenv returns NULL if no match & prematurely terminates search;
* remove undeclared NULL pointer, P_tmpdir, from the list;
* terminating NULL is required to stop search.
*/
const char *dirs[] = { getenv("TMPDIR"), "/tmp", NULL };
const char **dir;
/* The fix ... */
if ( dirs[0] == NULL ) dirs[0]=" ";
for (dir = dirs; *dir; dir++)
if (access(*dir, W_OK) == 0) {
tmpdir = *dir;
break;
}
/*
* alternative to the above:
* WARNING : not tested
const char env_tmp = getenv("TMPDIR"), sys_tmp="/tmp";
if ( access(env_tmp, W_OK) == 0 )
tmpdir = env_tmp;
else if ( access(sys_tmp, W_OK) == 0 )
tmpdir = sys_tmp;
*/
if (tmpdir)
{
_log("Storing temporary files in %s\n", tmpdir);
setenv("TMPDIR", tmpdir, 1); /* for child processes */
}
else
rip_die(EXIT_PRNERR_NORETRY_BAD_SETTINGS,
"Cannot find a writable temp dir.");
}
return tmpdir;
}
