In wget 1.7 and 1.6, if the WGETRC environment variable is set but the file
specified is inaccessible, the message:
wget: (null): No such file or directory.
is displayed and the program exits with status 1.
Debugging traces the problem to the following function in init.c (ca. line
261)
/* Return the path to the user's .wgetrc. This is either the value of
`WGETRC' environment variable, or `$HOME/.wgetrc'.
If the `WGETRC' variable exists but the file does not exist, the
function will exit(). */
static char *
wgetrc_file_name (void)
{
char *env, *home;
char *file = NULL;
/* Try the environment. */
env = getenv ("WGETRC");
if (env && *env)
{
if (!file_exists_p (env))
{
fprintf (stderr, "%s: %s: %s.\n", exec_name, file, strerror
(errno));
exit (1);
}
return xstrdup (env);
}
....
where the error message is printed
Firstly, file is a null pointer at the time that this error message is
printed; env is the correct pointer to use here. Secondly, there is no
explanation of why the program is looking for this file.
A possible fix is as follows:
278c278
< fprintf (stderr, "%s: Unable to access WGETRC specified in
environment: %s: %s.\n", exec_name, env, strerror (errno));
---
> fprintf (stderr, "%s: %s: %s.\n", exec_name, file, strerror
(errno));
the resultant output is now (when WGETRC is set to c:\.wgetrc, and this file
doesn't exist):
wget: Unable to access WGETRC specified in environment: c:\.wgetrc: No such
file
or directory.
Note: debugging and patching was done with version 1.6 source. I have
upgraded my executable to 1.7 and the bug still exists, but I haven't
obtained the source code to see if there are any changes in this function
between ver 1.6 and 1.7.
Warm Regards,
Chris
