-
-subst.c
- - new param flags value, PF_ASSIGNRHS, mirrors W_ASSIGNRHS, noting that
- parameter expansion is on rhs of assignment statement. That inhibits
- word splitting
- - change param_expand to call string_list_dollar_at with quoted == 1
- if PF_ASSIGNRHS is set, so it will quote IFS characters in the

-jobs.c
- - add sentinel to wait_sigint_handler so it only sets wait_sigint_received
- if waiting_for_child is non-zero; otherwise, it restores the old
- SIGINT handler and sends itself the SIGINT
- - set waiting_for_child around the calls to waitchld that use it to
- synchronously wait for a process
- - change logic that decides whether or not the child process blocked
- or handled SIGINT based on whether or not waitpid returns -1/EINTR
- and the shell receives a SIGINT and the child does not exit. If
- the child later exits due to SIGINT, cancel the assumoption that it
- was handled
- - instead of testing whether or not the child exited due to SIGINT
- when deciding whether the shell should act on a SIGINT it received
- while waiting, test whether or not we think the child caught
- SIGINT. If it did, we let it go (unless the shell has it trapped);
- if it did not catch it, the shell acts on the SIGINT. Fix from

- are handled right
-
-parse.y
- - don't need to set terminate_immediately in yy_stream_get, since

-
-bashline.c

- expansion, as if the word were outside double quotes. In effect,

- filename_stat_hook that does $PATH searching the same way that
- execute_cmd.c:execute_disk_command() does it, and rewrites the
- passed filename if found. Does not put names into command hash
- table. This allows command name completion to take advantage
- of `visible-stats' and `colored-stats' settings.
- - executable_completion: new function, calls the directory completion
- hook to expand the filename before calling executable_file or
- executable_or_directory; change command_word_completion_function to

-redir.c
- - redirection_expand, write_here_string, write_here_document: before
- calling any of the word expansion functions, after setting
- expanding_redir to 1 (which bypasses the temp environment in the
- variable lookup functions), call sv_ifs to reset the cached IFS-
- related variables set by subst.c:setifs(). This ensures that
- redirections will not get any IFS values that are set in the
- temporary environment, as Posix specifies. Then, after the word
- expansions, after resetting expanding_redir to 0, call sv_ifs
- again to make sure the cached IFS values are set from any
- assignments in the temporary environment. We force executing_builtin
- to 1 to `fool' the variable lookup functions into using any temp
- environment, then reset it to its old value after sv_ifs returns.

- declare -n foo=bar

-builtins/set.def
- - unset_builtin: if we find a nameref variable when we look it up with

- function rather than rely on unbind_variable to do the same thing as
- find_variable. Fixes problem reported by Greg Wooledge
- <wooledg@eeg.ccf.org>
- - unset_builtin: if we try to unset a nameref variable whose value is
- not a set variable, make sure we don't try to unset the nameref
- itself, but rather the variable it points to. This ensures that the

-lib/readline/display.c
- - rl_redisplay: fix code that deals with prompts that contain
- multibyte characters whose physical length is longer than the screen
- width (so the prompt line wraps) to deal with invisible characters
- in the prompt and set the inv_lbreaks offsets correctly and set
- lpos appropriately
- - _rl_move_cursor_relative: always called with either visible line or
- invisible line. Decide whether we are being called with the invisible
- line (or a portion thereof) as the DATA argument; make sure to account
- for invisible characters in the last line of the prompt by offsetting
- the desired buffer offset (NEW) by where DATA starts in invisible line
- and checking whether that is past the last invisible character in
- the prompt
- - _rl_move_cursor_relative: do the same for the visible line by using
- the visible line lbreaks array instead of _rl_screenwidth, since
- that fails in the presence of multibyte characters (buffer offset
- vs. physical screen position). These fix bug with prompts with
- multibyte characters and invisible characters that are longer than
- the screen width reported by Ryo Furue <ryofurue@gmail.com>

+ variable lookup functions), call sv_ifs to reset the cached IFS-
+ related variables set by subst.c:setifs(). This ensures that
+ redirections will not get any IFS values that are set in the
+ temporary environment, as Posix specifies. Then, after the word
+ expansions, after resetting expanding_redir to 0, call sv_ifs
+ again to make sure the cached IFS values are set from any
+ assignments in the temporary environment. We force executing_builtin
+ to 1 to `fool' the variable lookup functions into using any temp

+ is set, not only when SIGINT is not trapped. check_signals_and_traps
+ will call check_signals, which calls QUIT, which will longjmp back
+ to top_level, running the interrupt trap along the way. Fixes the
+ problem of signal handlers being reset out from under readline, and

+ - rl_display_match_list: when calculating common prefix to display in
+ color, make sure we correctly handle a common prefix with a trailing
+ `/' as we do when checking whether or not to add an ellipis.
+ printable_part() doesn't return the whole pathname if it ends in a
+ slash, to avoid printing null strings, so we have to make sure we
+ have the entire prefix
+
+lib/readline/complete.c
+ - _rl_complete_display_matches_interrupt: new variable, set to 1 by
+ _rl_complete_sigcleanup to let rl_display_match_list know it has

+
+builtins/declare.def
+ - declare_internal: don't try to perform compound assignments unless

+builtins/declare.def
+ - declare_internal: keep track of whether or not an assignment statement

+ differentiate assignments from straight declarations (declare a[4])
+ which are accepted for backwards compatibility
+ - assignment statements like declare a[2]=foo are now treated as
+ straight subscript assignment statements if a already exists as an
+ array variable
+ - declare foo='(1 2 3)' is treated as an assignment to foo[0] if foo
+ exists and is an array, just as it would be if it were an assignment
+ statement and `declare' was not present. All this from a proposal

+lib/readline/histfile.c
+ - read_history_range: implement a heuristic that temporarily sets the
+ history comment character if the first line read from the history
+ file looks like it has is a timestamp (#[:digit:]) so we can read
+ timestamps from the history file properly. Originally reported
+ back in March 2015 by Christoph Anton Mitterer <calestyo@gmail.com>
+ - read_history_range: make sure history_multiline_entries is non-zero
+ if the history file looks like it has timestamps
+ - read_history_range: if we think we have a history file with timestamps
+ and we read more than one non-timestamp consecutive history lines,
+ assume they are part of a single multi-line history entry and paste
+ them together using _hs_append_history_line. Feature most recently

+bashhist.c
+ - bash_history_inhibit_expansion: fix cases where a history expansion
+ should be skipped because it's in a command or process substitution
+ but there is another history expansion preceding the substitution
+ on the command line. Don't let the previous history expansion fool
+ the function into saying the command substitution history expansion
+ should be performed
+
+builtins/evalstring.c
+ - parse_prologue: always unwind-protect history_expansion_inhibited,
+ since history expansion can be enabled in non-interactive shells,
+ and calling eval once in a non-interactive shell inhibits history
+ expansion forever even if `set -o histexpand' was run before the
+ eval
+
+builtins/common.h
+ - SEVAL_NOHISTEXP: new flag for parse_and_execute/parse_string; means
+ to not perform history expansion (decouple from SEVAL_NOHIST, which
+ now means to not remember commands on history); changed all callers
+ that had SEVAL_NOHIST to have SEVAL_NOHIST|SEVAL_NOHISTEXP
+
