- glob_char_p: add more of the extglob pattern characters; it doesn't
|
||||
hurt to quote them
|
||||
Report and patch from Grisha Levit <grishalevit@gmail.com>
|
||||
- unquoted_glob_pattern_p: don't treat a `(' immediately following a
|
||||
`/' as a potential globbing character
|
||||
- unquoted_glob_pattern_p: only treat the extended glob characters
|
||||
followed by a `(' as a glob pattern if extended_glob is enabled
|
||||
- unquoted_glob_pattern_p: an unquoted backslash isn't treated
|
||||
specially any more, but if it's followed by a CTLESC, you still
|
||||
don't treat the next character as an unquoted globbing char

- get_numeric_arg: if fatal > 0, set the exit status to EX_USAGE
|
||||
and call jump_to_top_level with EXITPROG or DISCARD. We don't
|
||||
need to do everything that throw_to_top_level() does here (it's
|
||||
really meant for signals and other exceptional failure conditions).

builtins/cd.def
|

- cd_builtin: exit with EX_USAGE on too many arguments
|
||||
|
||||
builtins/shift.def
|
||||
- shift_builtin: return EX_USAGE if get_numeric_arg returns 0,
|
||||
indicating that the argument wasn't a valid number
|

|
||||
builtins/history.def
|
||||
- shift_builtin: return EX_USAGE if get_numeric_arg returns 0
|

builtins/exit.def
|
||||
- exit_or_logout: if get_exitstat (which calls get_numeric_arg) returns
|
||||
a value > EX_SHERRBASE, indicating an error, just return that to
|
||||
the caller and let the caller deal with it. This means that
|
||||
`exit xyz' is no longer a fatal error, but can potentially cause a
|
||||
non-interactive posix-mode shell to exit because exit is a special
|
||||
builtin
|
||||
|
||||
builtins/return.def
|
||||
- return_builtin: if a non-interactive shell in posix mode gets an
|
||||
invalid numeric arg from get_exitstat, return immediately and let
|
||||
the caller deal with exiting
