ael-code	a4578815f1	cleanup output-background subcommand handling - fixes a double-free error when access() failed. - refactor code to make memory managment (alloc/free) more straightforward - do not bring the temporary wordexp_t struct around - do not postpone errors handling	8 years ago
ael-code	4550cb2b3e	fix memleak on background cmd error - src must be free after join_args() - wordfree must bee used after wordexp	8 years ago
ael-code	ad085c1332	bugfix: avoid access after free if src is NULL due to a previous error we cannot use it in the command result string. Moreover if `src` points to `p.we_wordv[0]` we cannot use it after `wordfree(&p)` in the command result string. Bonus feature: If there was an error accessing the file, the string rapresentation of the error is now included in the command result string.	8 years ago
