Bash-4.3 changed +to dequote the argument to programmable completion only under certain +circumstances, to make the behavior of compgen more consistent when run +from the command line -- closer to the behavior when run by a shell function +run as part of programmable completion. Bash-completion can pass quoted +arguments to compgen when the original word to be completed was not quoted, +expecting programmable completion to dequote the word before attempting +completion. + +This patch fixes two cases: + +1. An empty string that bash-completion passes to compgen as a quoted null + string (''). + +2. An unquoted word that bash-completion quotes using single quotes or + backslashes before passing it to compgen. + +In these cases, since readline did not detect a quote character in the original +word to be completed, bash-4.3 + +*** ../bash-4.3/externs.h 2014-01-02 14:58:20.000000000 -0500 +--- externs.h 2014-03-13 14:42:57.000000000 -0400 +*************** +*** 325,328 **** +--- 325,329 ---- + extern char *sh_backslash_quote_for_double_quotes __P((char *)); + extern int sh_contains_shell_metas __P((char *)); ++ extern int sh_contains_quotes __P((char *)); + + /* declarations for functions defined in lib/sh/spell.c */ +*** ../bash-4.3/lib/sh/shquote.c 2013-03-31 21:53:32.000000000 -0400 +--- lib/sh/shquote.c 2014-03-13 14:42:57.000000000 -0400 +*************** +*** 312,313 **** +--- 312,327 ---- + return (0); + } ++ ++ int ++ sh_contains_quotes (string) ++ char *string; ++ { ++ char *s; ++ ++ for (s = string; s && *s; s++) ++ { ++ if (*s == '\'' || *s == '"' || *s == '\\') ++ return 1; ++ } ++ return 0; ++ } +*** ../bash-4.3/pcomplete.c 2013-08-26 15:23:45.000000000 -0400 +--- pcomplete.c 2014-03-25 17:23:23.000000000 -0400 +*************** +*** 184,187 **** +--- 184,188 ---- + COMPSPEC *pcomp_curcs; + const char *pcomp_curcmd; ++ const char *pcomp_curtxt; + + #ifdef DEBUG +*************** +*** 754,757 **** +--- 755,784 ---- + dfn = (*rl_filename_dequoting_function) ((char *)text, rl_completion_quote_character); + } ++ /* Intended to solve a mismatched assumption by bash-completion.
