Hey Serge,
To be honest I wasn't thinking about parse errors while sending the patch.
Maybe we can handle the non-existent file issue with something like that
diff --git a/src/lxc/confile.c b/src/lxc/confile.c
index 8fe1541..96f9122 100644
--- a/src/lxc/confile.c
+++ b/src/lxc/confile.c
@@ -1422,6 +1422,11 @@ int lxc_config_readline(char *buffer, struct
lxc_conf *conf)
int lxc_config_read(const char *file, struct lxc_conf *conf)
{
+ /* make sure file exists and reabable by us */
+ if( access(file, R_OK) == -1 ) {
+ return -1;
+ }
+
/* Catch only the top level config file name in the structure */
if( ! conf->rcfile ) {
conf->rcfile = strdup( file );
and address parse errors differently?
Cheers,
