-builtins/fc.def
- - fixed an off-by-one error that caused `fc -l' to list one too many

-general.c
- - changed base_pathname so that it will return reasonable results for
- non-absolute pathnames -- this is what is intended by all of its

-
-builtins/command.def
- - `command -V' passes a new flag, CDESC_ABSPATH, which means to convert
- to an absolute path
-
-builtins/type.def
- - in posix mode, `type' and `command -v/-V' should not report
- non-executable files, even if the execution code will attempt to

-
-subst.c
- - fix a couple of instances of find_variable that didn't check the

+parse.y
+ - when adding $$ to the current token buffer in read_token_word(),

-variables.c
- - BASH_ARGC, BASH_ARGV, BASH_SOURCE, BASH_LINENO no longer created as
- invisible vars
+execute_cmd.c
+ - fix expand_word_unsplit to add the W_NOSPLIT2 flag to the word to
+ be expanded, so "" doesn't add CTLNUL. Similar to fix of 2/18 to

+ <nathanael@gnat.ca> and Matthias Klose <doko@debian.org>
-pcomplete.c

- - ditto for COMPREPLY in gen_shell_function_matches
+parse.y

+ - TENTATIVE: fix read_token_word to reduce the amount of buffer space

+ CTLESC before a CTLESC or CTLNUL, and before adding the character if
+ we're not adding a CTLESC. Report and fix from
+ Michael Witten <mfwitten@gmail.com>
+
+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

-lib/readline/vi_mode.c
- - in rl_vi_search, free any saved history line before starting 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);

-lib/readline/readline.c
- - fix _rl_dispatch_subseq in the case where we're recursing back up
- the chain (r == -2) and we encounter a key shadowed by a keymap,
- but originally bound to self-insert. Calling rl_dispatch with
- ANYOTHERKEY as the first argument will call rl_insert, but with
- ANYOTHERKEY (256) as the char to insert. Use the shadow keymap
- and set things up to dispatch to rl_insert with the shadowed key
- as the argument. Fixes the bug reported by Thomas Glanzmann

-builtins/read.def
- - check whether or not the number of fields is exactly the same as

- - change rl_vi_redo to use _rl_vi_backup to move point backward
- after redoing `i' or `a'
-
-jobs.c
- - new function, delete_old_job (pid), checks whether or not PID is in
- a job in the jobs list. If so, and the job is dead, it just removes
- the job from the list. If so, and the job is not dead, it zeros
- the pid in the appropriate PROCESS so pid aliasing doesn't occur
- - make_child calls delete_old_job to potentially remove an already-used
- instance of the pid just forked from the jobs list if pids have
- wrapped around. Finally fixes the bug reported by Tim Waugh

- set_signal
-
-jobs.c
- - in wait_for, if the original SIGINT handler is SIG_IGN, don't set

-parse.y
- - in parse_comsub, when looking for a reserved word (LEX_RESWDOK
- non-zero), and in a case statement, we can see either an esac
- or a pattern list. We handle an esac separately. We should
- turn off LEX_RESWDOK if we see anything but a newline, since
- we'll be reading a pattern list. Other part of fix for bug
- reported by Mike Frysinger <vapier@gentoo.org> (rest of fix
- on 3/3)

+ appropriate members of struct stat into `struct timespec' values,
+ zeroing out the tv_nsec field if necessary

-lib/readline/bind.c
- - fix rl_generic_bind in the case where we are trying to override a

- can't use a NULL function pointer in ANYOTHERKEY since that's
- indistinguishable from the keymap not having been overridden at all.

+input.c
+ - getc_with_restart: if read(2) returns -1/EINTR and interrupt_state or
+ terminating_signal is set (which means QUIT; will longjmp out of this
+ function), make sure the local buffer variables are zeroed out to
+ avoid reading past the end of the buffer on the next call. Bug report

+ quote characters, we need to quote them before passing the candidate
+ path to rl_filename_completion_function, which performs dequoting on

+parse.y
+ - xparse_dolparen: save and restore shell_eof_token around call to
+ parse_string, intead of just leaving it set to ')'
+ - shell_getc: when -v is set, only print the command line when
+ shell_eof_token is 0, so we don't print it multiple times when
+ recursively entering the parser to parse $(...) commands. Fixes

+ - find_variable_nameref_context: fix a problem that caused the loop
