                                 4/9/2001
                                 --------
[bash-2.05 released]

                                   4/10
                                   ----
redir.c
        - check return value of fclose() in write_here_document() for error
          returns; don't just rely on fwrite() failing

support/bashbug.sh
        - set TMPDIR to /tmp if it's null or unset
        - use $TMPDIR in the TEMP tempfile name template
        - fixed the call to `mktemp', if it exists, to make it more portable

jobs.c
        - if WCONTINUED is not defined, define it to 0 and add a define for
          WIFCONTINUED(wstatus) which expands to 0
        - add WCONTINUED to the flags passed to waitpid(2) in waitchld()
        - don't increment children_exited if waitpid's status is WIFCONTINUED,
          since we don't want to call a SIGCHLD trap handler in this case
        - in waitchld(), we set child->running to 1 if WIFCONTINUED(status)
          is non-zero
        - make sure pretty_print_job doesn't check for the core dump bit if
          the process has been continued; it's only valid if the job is dead
        - in set_job_status_and_cleanup, set the job to JRUNNING if job_state
          is non-zero and the job was previously marked as JSTOPPED

configure.in
        - add -DBROKEN_DIRENT_D_INO to interix LOCAL_CFLAGS

lib/glob/glob.c
        - if BROKEN_DIRENT_D_INO is defined, define REAL_DIR_ENTRY to 1

jobs.c
        - in kill_pid, we only need to block and unblock SIGCHLD if the
          `group' argument is non-zero, since otherwise we just call `kill'
          on the pid argument

version.c
        - update copyright date to 2001

bashline.c
        - prog_complete_return needs to take a `const char *' as its first
          argument
        - history_completion_generator needs to take a `const char *' as
          its first argument, and `text' needs to be a `const char *'

                                   4/11
                                   ----
redir.c
        - fixed a weird typo in redir_special_open, case RF_DEVFD, added
          call to all_digits before call to legal_number
        - fixed do_redirection_internal to call legal_number instead of atol(3)
          when translating r_duplicating_{in,out}put_word, so it handles
          overflow better
        - produce an error message in redirection_error for out-of-range
          file descriptors
        - change allocation strategy in redirection_error so we don't have to
          malloc scratch memory if redirection_expand() fails

jobs.h
        - added defines for `running' member of a struct process

general.c
        - fix legal_number to return 0 when strtol(3) reports overflow or
          underflow

parse.y
        - changed read_token_word to call legal_number instead of atoi(3)

input.c
        - return -1/EBADF from close_buffered_fd if fd is < 0

command.h
        - fixed bogus comment about IS_DESCRIPTOR in description of the
          REDIRECTEE struct

print_cmd.c
        - change cprintf's 'd' modifier code to display negative numbers as
          an out-of-range value.  We can do this only because the only use
          of %d is to output file descriptor numbers in redirections

support/mksignames.c
        - need to include config.h to get a possible value for
          UNUSABLE_RT_SIGNALS

                                   4/16
                                   ----
lib/readline/doc/rluser.texinfo
        - corrected a small error in one description of M-DEL

                                   4/17
                                   ----
stringlib.c
        - need to initialize `ind' before calls to RESIZE_MALLOCED_BUFFER
          in strcreplace()

support/bashversion.c
        - new file, prints bash version information

Makefile.in
        - rules for building bashversion and linking it to version.o

                                   4/24
                                   ----
conftypes.h
        - new file with HOSTTYPE, OSTYPE, MACHTYPE, etc. defines from
          variables.h

variables.h, version.c
        - include conftypes.h

patchlevel.h
        - new file, contains define for PATCHLEVEL.  Doing away with the old
          scheme of having the information in configure.in

version.c
        - include patchlevel.h

Makefile.in
        - run bashversion -p to find patch level rather than have configure
          substitute in a value
        - pass -S ${top_srcdir} to support/mkversion.sh

support/mkversion.sh
        - don't put PATCHLEVEL define into version.h, but accept and ignore
          a -p option
        - take a new -S srcdir option
        - find the patch level by parsing it out of patchlevel.h

configure.in
        - hard-code BASHVERS assignment instead of reading it from a file
        - remove BASHPATCH; don't substitute it

_distribution,_patchlevel
        - removed

                                   4/26
                                   ----
shell.c
        - call init_noninteractive() in open_shell_script if forced_interactive
          is non-zero (the shell was started with -i) and fd_is_tty is 0
          (the script file is a real file, not something like /dev/stdin),
          since it wasn't done earlier

builtins/printf.def
        - change for POSIX.2 compliance when conversion errors are encountered
          when processing %d, %u, and floating point conversion operators
          (print a warning message, return the value accumulated at the time
          of the error -- which is always 0 -- and exit with a non-zero status)

command.h
        - added CMD_COMMAND_BUILTIN for use by the `command' builtin and the
          code in execute_cmd.c

builtins/command.def
        - add CMD_COMMAND_BUILTIN to the created command's flags

                                    5/1
                                    ---
configure.in
        - add call to AC_C_CONST to test `const' compiler behavior
        - add call to AC_C_INLINE to test `inline' compiler behavior
        - add call to AC_C_STRINGIZE to test cpp #x stringizing operator

config.h.in
        - add `#undef const' for configure to substitute
        - add `#undef inline' for configure to substitute
        - add `#undef HAVE_STRINGIZE' for configure to substitute

include/stdc.h
        - remove code that defines or undefines `const' and `inline'
        - change the __STRING macro to be defined depending on the value
          of HAVE_STRINGIZE

lib/malloc/malloc.c
        - change the __STRING macro to be defined depending on the value
          of HAVE_STRINGIZE

lib/readline/{readline,rlprivate}.h
        - moved rl_get_termcap to readline.h, making it a public function

lib/readline/readline.h
        - new #define, RL_READLINE_VERSION, hex-encoded library version
          number, currently set to 0x0402
        - new public int variable, rl_readline_version

lib/readline/readline.c
        - #define RL_READLINE_VERSION if it is not already defined (which it
          should be in readline.h)
        - initialize rl_readline_version to RL_READLINE_VERSION

lib/readline/doc/rltech.texinfo
        - documented rl_get_termcap
        - documented rl_readline_version

jobs.c
        - job_exit_status should return an int, not a WAIT (undetected
          before because on most POSIX-like systems a WAIT is really an int)

builtins/evalfile.c
        - added FEVAL_REGFILE (file must be a regular file) to accepted
           _evalfile flags
        - fc_execute_file() adds FEVAL_REGFILE to _evalfile flags.  This
          means that startup files and files read with `.' no longer need
          to be regular files

                                    5/2
                                    ---

lib/termcap/Makefile.in
        - fix target for installed termcap library (normally unused)

lib/tilde/Makefile.in
        - fix install target to install in $(libdir) (normally unused)

Makefile.in
        - don't make $(man3dir) since there's nothing installed there

Makefile.in,doc/Makefile.in
        - change `man1ext' to `.1', `man3ext' to `.3'
        - change appropriate install targets to use new values of man[13]ext
        - use `test ...' instead of `[...]'
        - add support for DESTDIR root installation prefix, for package
          building (installdirs, install, install-strip, uninstall targets)

builtins/common.c
        - new function int get_exitstat(WORD_LIST *list) returns an eight-bit
          exit status value for use in return, exit, logout builtins

builtins/common.h
        - extern declaration for get_exitstat()

builtins/{exit,return}.def
        - call get_exitstat where appropriate

builtins/printf.def
        - add support for "'" flag character as posix 1003.2-200x d6 says
        - fix core dump when user-supplied field width or precision is 0
        - fix to printstr() to handle zero-length precision with `%b' format
          specifier (printf '%.0b-%.0s\n' foo bar)
        - fix to printstr() to treat a negative field width as a positive
          field width with left-justification
        - fix to mklong to avoid static buffers, which can always be overrun
          by someone sufficiently motivated

bashline.c
        - change var in add_host_name to type `size_t' for passing to xrealloc

                                    5/3
                                    ---
execute_cmd.c
        - change restore_signal_mask to accept a sigset_t *, since a sigset_t
          may not fit into a pointer, change call

unwind_prot.c
        - use a union UWP in restore_variable when restoring a variable whose
          size is the same as sizeof(int), the reverse of the method used to
          store it in unwind_protect_int

builtins/printf.def
        - use a #define LENMODS containing the length modifiers instead of
          testing against each possible modifier character, save any mod
          character found
        - add support for ISO C99 length specifiers `j', `t', and `z'
        - if `L' modifier is supplied with a floating point conversion char,
          pass a `long double' to printf if HAVE_LONG_DOUBLE is defined

configure.in,config.h.in
        - call AC_C_LONG_DOUBLE to check for `long double'; define
          HAVE_LONG_DOUBLE if supported

bashline.c
        - fix an inadvertantly-unclosed comment in attempt_shell_completion
        - make set_saved_history return a value
        - make dynamic_complete_history return a useful value

{make_cmd,execute_cmd,shell,subst,trap,variables,input,unwind_prot,test,
pcomplete}.c
        - removed some declared-but-unused variables

builtins/{cd,enable,fc,set,setattr,type,umask,printf,complete}.def
        - removed some declared-but-unused variables

lib/sh/{zread,netopen}.c
        - removed some declared-but-unused variables

execute_cmd.c
        - in execute_arith_command, use a long variable to hold the result
          of evalexp(), since that's what it returns

builtins/evalstring.c
        - make cat_file return -1 on a read or write error

lib/sh/stringlib.c
        - make merge_stringlists() return the right value

                                    5/7
                                    ---
pcomplete.c
        - remove typo that caused empty declaration (;;)

parse.y
        - fix yyerror() to accept a single string argument; fix callers

trap.c
        - cast pointer to long instead of int when printing message with
          internal_warning() in run_pending_traps()

subst.c
        - fix process_substitute to handle stdin being closed

test.c
        - change `while' to `if' in and() and or(), since the loop isn't
          actually performed -- there's an unconditional `return' in the
          loop body
        - check for integer overflow of arguments to `-t'

lib/sh/netopen.c
        - change _getserv() to reject negative port/service numbers

expr.c
        - fix strlong() to not convert the base specification from long to
          int before checking for overflow, since truncation on machines
          where sizeof(int) != sizeof(long) may mask errors

builtins/{jobs,kill,wait}.def
        - use legal_number instead of atoi when converting strings to pid_t;
          check for numeric overflow

input.c
        - fix for cygwin in b_fill_buffer -- off-by-one error when checking
          buffer for \r\n termination

general.h
        - new #define INT_STRLEN_BOUND(t), computes max length of string
          representing integer value of type T, possibly including a sign
          character
        - include <limits.h> if it's present

{execute_cmd,findcmd,test}.c
        - don't include <limits.h>, since general.h does it now

{execute_cmd,lib/sh/itos,pcomplete,print_cmd,subst,variables}.c
        - use INT_STRLEN_BOUND instead of static array sizes when converting
          various strings to integer values

shell.h
        - struct fd_bitmap now uses an `int' size, since it's bounded by
          the number of file descriptors, which must fit into an `int'

execute_cmd.c
        - FD_BITMAP_DEFAULT_SIZE is now 32, not 32L
        - new_fd_bitmap takes an `int' size parameter, not a `long'

execute_cmd.h
        - change prototype for new_fd_bitmap()

test.c
        - fix test_stat to check for overflow when parsing the integer file
          descriptor number; return ENOENT instead of EBADF for files that
          are not open

hashlib.c
        - don't discard the upper 32 bits of the random value, if present

lib/readline/shell.c
        - use the same INT_STRLEN_BOUND mechanism to decide how much space to
          allocated in sh_set_lines_and_columns

                                    5/8
                                    ---
aclocal.m4
        - add check for libtinfo (termcap-specific portion of ncurses-5.2) to
          BASH_CHECK_LIB_TERMCAP
        - new macro, RL_LIB_READLINE_VERSION, checks version of installed
          readline library and (optionally) writes version #defines to
          config.h.  Bash doesn't use the version defines

configure.in
        - call RL_LIB_READLINE_VERSION instead of support/rlvers.sh

execute_cmd.c
        - fix execute_shell_script and the WHITECHAR and STRINGCHAR macros
          to check array bounds before indexing into the sample string

unwind_prot.[ch]
        - import new versions submitted by Paul Eggert <eggert@twinsun.com>
          with a couple of changes for backwards compatibility, so the rest
          of the source doesn't need to be changed yet

jobs.c
        - use unwind_protect_var on last_made_pid in run_sigchld_trap

builtins/bind.def
        - use unwind_protect_var on rl_outstream

general.c
        - rework print_rlimtype to use INT_STRLEN_BOUND and handle the
          most negative number correctly

expr.c
        - `tokval' should have been a `long', since all arithmetic is done
          as longs

builtins/history.def
        - consolidate tests for valid history position in one block to
          avoid duplicate code and strings

builtins/ulimit.def
        - fix check for overflow when setting limit to work when int is 32
          bits and RLIMTYPE is 64

lib/sh/tmpfile.c
        - don't truncate the result of time(3) to int; just use time_t,
          since it's being assigned to an `unsigned long'

mailcheck.c
        - use legal_number instead of atoi in time_to_check_mail() to catch
          more numeric errors; consolidate error checking in one block
        - last_time_mail_checked should be a time_t

                                    5/9
                                    ---
builtins/set.def
        - recognize `set [-+]o nolog' if HISTORY is defined

bashline.c
        - new variable `dont_save_function_defs', set by `set -o nolog';
          currently ignored

command.h
        - the `dest' member of a REDIRECTEE is now an `int'

parse.y,redir.c
        - changed uses of `redir.test' (where redir is a REDIRECTEE) since
          it's now an int

lib/readline/rlstdc.h
        - don't mess around with `const', rely on configure to supply a
          proper definition if the compiler doesn't support it

lib/tilde/tilde.h
        - include <config.h> if HAVE_CONFIG_H is defined
        - don't mess around with `const', rely on configure

builtins/shopt.def
        - new read-only `shopt' option, login_shell, non-zero if shell is a
          login shell (as decided by shell.c)
        - new function set_login_shell(), sets shopt private value of
          login_shell

builtins/common.h
        - new extern declaration for set_login_shell

shell.c
        - call set_login_shell after setting value of login_shell (in
          main() and set_shell_name())

        - added new `\A' prompt string escape sequence:  time in 24-hour
          HH:MM format

configure.in, config.h.in
        - check for <grp.h>, define HAVE_GRP_H if found

        - add new `-A group/-g' option to complete group names

pcomplete.h
        - new define for CA_GROUP, used with group name completion

        - extern declaration for _rl_match_hidden_files

builtins/hash.def
        - new `-t' option to list hash values for each filename argument

        - alarm(3) takes an `unsigned int' argument, not int
        - check for arithmetic overflow with -t and -n options

input.c
        - check for read error before doing \r\n translation on cygwin in
          b_fill_buffer
        - reset bp->b_used to 0 instead of leaving it at -1 on read error
          in b_fill_buffer

builtins/shopt.def
        - new functions, shopt_setopt(name, mode) and
          shopt_listopt(name, mode) to give the rest of the shell an easy
          interface

builtins/common.h
        - extern declarations for shopt_setopt and shopt_listopt

shell.c
        - new invocation options -O and +O, to list or set/unset shopt

lib/sh/zread.c
        - int -> ssize_t fixes to mirror modern declarations of read and write
        - the `off' variable in zsyncfd should be an off_t since it computes
          a file offset
        - the local buffer `lbuf' is now char, since it's not nice to pass
          unsigned char * to read(2), and the values from it are assigned to
          a char anyway
        - lind and lused are now size_t, since they index into a buffer
        - set lused to 0 on read error

lib/sh/zwrite.c

          to pass a `char *' to `write'

builtins/evalstring.c
        - the number of chars read with zread in cat_file should be assigned
          to a variable of type ssize_t

input.c
        - the number of chars read with zread in b_fill_buffer should be
          assigned to a variable of type ssize_t
        - `localbuf' is now type char[], since POSIX says you shouldn't pass
          unsigned char * to read(2)
        - in getc_with_restart(), use a variable of type unsigned char to
          get a value from the local buffer and return it
        - in ungetc_with_restart, explicitly return the character arg passed
          to avoid relying on localbuf being unsigned char

subst.c
        - the number of chars read with zread in read_comsub should be
          assigned to a variable of type ssize_t

mksyntax.c
        - instead of casting to unsigned char * in addcstr, use a variable
          of type unsigned char and let the compiler do the work

parse.y
        - instead of casting to unsigned char * in yy_readline_get, use a
          variable of type unsigned char and let the compiler do the work

          library version for use by the caller
        - change RL_LIB_READLINE_VERSION to not compute ac_cv_rl_prefix if
          the caller has already assigned it a value
        - rename _rl_prefix -> ac_cv_rl_prefix, _rl_libdir -> ac_cv_rl_libdir,
          _rl_includedir -> ac_cv_rl_includedir

configure.in
        - change testing of whether to use the value of
          $opt_with_installed_readline to be != no, to allow the user to
          specify a prefix where the installed readline library may be found
        - if --with-installed-readline=PREFIX is supplied, set ac_cv_rl_prefix
          to PREFIX before calling RL_LIB_READLINE_VERSION
        - if --with-installed-readline[=PREFIX] is supplied, don't set
          RL_LIBDIR and RL_INCLUDEDIR; let RL_LIB_READLINE_VERSION take care
          of it, set RL_INCLUDE=-I${RL_INCLUDEDIR}
        - if --with-installed-readline[=PREFIX] is supplied, and we're
          linking with the history library, assign $RL_LIBDIR to HIST_LIBDIR
          so we use the same version of the installed readline and history
          libraries

Makefile.in, builtins/Makefile.in
        - have configure substitute RL_INCLUDEDIR, set RL_INCLUDEDIR variable

doc/bashref.texi

pcomplete.c
        - changed some function parameters to `const char *' to avoid discarding
          const qualifier

        - make_bare_word, make_word_flags, and make_word now take a
          `const char *' string argument

print_cmd.c
        - cprintf now takes a `const char *' as its first argument, like

        - the conditional define for xprintf should have been HAVE_VPRINTF,
          not HAVE_VFPRINTF

shell.c
        - in isnetconn(), the return value of sizeof() is size_t

aclocal.m4
        - add inclusion of stddef.h if STDC_HEADERS is defined to 1 in
          BASH_CHECK_TYPE

{subst,variables,lib/sh/tmpfile}.c
        - dollar_dollar_pid is now a `pid_t' instead of `int'

variables.c
        - sbrand() now takes an `unsigned long' to set the seed value
        - changed last_random_value to type int, since it's always between
          0 and 32767
        - use strtoul to convert the value in assign_random instead of atoi
        - take out casts in any arguments to sbrand()

          least set the last character in msg_buf to 0 to avoid overrun --
          we really can't do anything about overflow at this point.  if it's

execute_cmd.c
        - in execute_command_internal, keep track of ERR trap and call it if

        - in execute_function, arrange things so the ERR trap is not inherited
          by shell functions, and is saved and restored like the DEBUG trap

doc/{bash.1,bashref.texi}
        - documented new ERR trap

tests/{trap.{tests,right},trap2.sub,trap2a.sub}

subst.c
        - on machines without /dev/fd, change the named pipe fifo list to a

        - don't redefine some is* ctype macros/functions if HAVE_ISXXX is
          defined (meaning that an appropriate function, but not a macro,
          exists)

lib/sh/strtrans.c
        - new function, ansic_shouldquote, returns 1 if argument string
          contains non-printing chars that should be quoted with $'...'

externs.h
        - new declaration for ansic_shouldquote()

variables.c
        - change print_var_value to ansi C quote the string if we're not in
          posix mode and the variable's value contains non-printing chars,
          to use the regular shell single quoting if the value contains
          shell meta-characters, and to just output the string otherwise

lib/sh/shquote.c
        - add `break' to `case '~':' to avoid fallthrough and extra test

doc/bashref.texi
        - note that in POSIX mode, `set' displays variable values that
          include nonprinting characters without quoting, unless they
          contain shell metacharacters

builtins/printf.def, lib/sh/snprintf.c
        - handle `F' conversion specifier as equivalent to 'f'

parse.y, {nojobs,variables}.c
        - a couple of cleanups for when building a minimal configuration

nojobs.c
        - new function: stop_making_children(), just sets
          already_making_children to 0 (like stop_pipeline)

subst.c
        - call stop_making_children from subst.c:command_substitute if
          JOB_CONTROL is not defined.  This fixes the bug where the wrong
          process is waited for (and its status returned) when using
          command substitution in a null command in a shell function

builtins/printf.def
        - new variable `tw' used to keep track of the total number of
          characters written by a single call to `printf' -- to be
          used for the `%n' conversion, which will be added later.  It
          gets reset each time we reuse the format string, which is what
          ksh93 seems to do

variables.h
        - extern declaration for bind_var_to_int

lib/sh/netopen.c
        - use gai_strerror() for error messages when getaddrinfo() fails

Makefile.in
        - pass DEBUG=${DEBUG} down to makes in some subdirectories

{builtins,lib/{glob,sh}}/Makefile.in
        - append ${DEBUG} to LOCAL_CFLAGS value, passed by top-level Makefile

builtins/printf.def
        - added support for %n format conversion char (number of chars printed
          so far from current format string)

        - call init_funcname_var, init_groups_var, init_dirstack_var,
          init_seconds_var from initialize_dynamic_variables
        - non-numeric values assigned to LINENO are treated as 0

        - change set_home_var to not auto-export HOME
        - change set_shell_var to not auto-export SHELL
        - broke the code that sets HOSTNAME, HOSTTYPE, MACHTYPE, OSTYPE
          out into a separate function, set_machine_vars; none of those
          variables are auto-exported
        - bash no longer un-exports SSH_CLIENT or SSH2_CLIENT

shell.c
        - changed isnetconn() to check SSH_CLIENT and SSH2_CLIENT only if
          SSH_SOURCE_BASHRC is defined in config-top.h

config-top.h
        - added a commented-out definition for SSH_SOURCE_BASHRC

builtins/read.def, parse.y

builtins/set.def
        - make sure unset_builtin() resets unset_array to 0 each time through
          the loop, because it's set (and used) depending on the current
          argument

shell.h
        - new define, USE_VAR, to force the compiler to not put a particular
          variable in a register -- helpful if registers are not restored
          by setjmp/longjmp

builtins/{evalfile.c,{read,wait}.def}, {eval,execute_cmd,shell,test}.c
        - use USE_VAR for some variables

subst.c
        - fixed a case in expand_word_internal where a NULL pointer could
          have been passed to free() (though free() should ignore it)
        - fixed a case at the end of expand_word_internal where LIST could
          have been used uninitialized (it makes gcc happy, though it
          doesn't happen in practice)

test.c
        - give test_syntax_error(), beyond(), and integer_expected_error()
          the `__noreturn__' attribute for gcc

unwind_prot.c
        - in clear_unwind_protect_list(), convert `flags' to `long' (via
          assignment to a `long' variable) before casting to `char *', in
          case pointers and longs are 64 bits and ints are 32 (makes no

{make_cmd,pcomplete,test}.c,parse.y
        - some minor changes to shut up gcc warnings

lib/sh/tmpfile.c
        - fixed sh_mktmpfp to avoid file descriptor leaks in the case that
          sh_mktmpfd succeeds but fdopen fails for some reason
        - change sh_mktmpfd to use the same scheme for computing `filenum'
          as sh_mktmpname
        - change get_sys_tmpdir to prefer P_tmpdir if P_tmpdir is defined
        - changed sh_mktmpname and sh_mktmpfd to avoid trying to assign to
          `nameroot' if `nameroot == 0' (duh)
        - add code to sh_mktmpfd to use mkstemp(3) if USE_MKSTEMP is defined
        - add code to sh_mktmpname to use mktemp(3) if USE_MKTEMP is defined

support/{fixlinks,mkclone}
        - use mktemp if it's available for the symlink test

support/bashbug.sh
        - more changes inspired by a patch from solar designer

lib/malloc/Makefile.in
        - new target `alloca', which builds libmalloc.a with alloca.o only
          (for systems without alloca that are configured --without-bash-malloc)

configure.in
        - if we don't have a working alloca and are not configured to build
          the bash malloc library, make a malloc library containing only
          alloca.o

aclocal.m4

          is in the initial environment

variables.c
        - fix function prologues for init_dirstack_var and init_groups_var
          to agree with caller (no arguments)

jobs.c
        - fix forward function declarations for pipe_read and pipe_close

subst.c
        - removed `inline' attribute from skip_double_quoted because it can

bashline.c

          completion code to just punt if the end of the command word found
          by find_cmd_end is <= the start found by find_cmd_start (the bug

pcomplete.c
        - fix gen_matches_from_itemlist to return if the stringlist is null

          returned by gen_matches_from_itemlist to `glist' if it's non-NULL

lib/sh/stringlist.c

          have an unclosed ${ or other expansion, return i immediately without
          doing a `continue' (which will increment i past the end of string)
        - in split_at_delims, don't increment te by 1 if it's pointing to a
          delimiter.  this has the effect of skipping the first delimiter
          char in a possibly multi-character delimiter, and ignoring

general.c

include/chartypes.h

          to the same as array variable assign_func.  Now this can be
          prototyped

variables.h
        - the assign_func member of a `struct variable' is now of type

        - the dynamic_value member of a `struct variable' is now of type

variables.c
        - changed to use `sh_var_assign_func_t' and `sh_var_value_func_t'

builtins/cd.def

        - if canonicalization failed, but the fallback to the directory
          name specified by the user succeeds, reset the current working
          directory

lib/readline/{input.c,rlprivate.h}
        - renamed rl_unget_char to _rl_unget_char; made library global

lib/readline/{{bind,readline}.c,{keymaps,rlprivate}.h}
        - support for `key subsequences'; allows a key sequence and a function
          mapped to a subsequence of that key sequence.  Primarily to allow
          arrow keys to be bound in readline vi insert mode, while preserving
          the ESC function to switch to command mode.

lib/readline/{input.c,rlprivate.h}
        - new function, _rl_input_queued(T), does a check with select or
          FIONREAD with a timeout of `T' (which is generally 0)

lib/readline/readline.c
        - change _rl_dispatch_subseq to test for input in the queue if we
          get ESC while in vi insertion mode if the keymap entry type for
          ESC is ISKMAP.  If _rl_input_queued returns non-zero, we assume
          that an arrow key sequence has been pressed and go ahead with the
          subsequence.  If it returns zero, we assume that the user pressed
          ESC to switch into command mode, and dispatch to that right away.
          This avoids forcing the user to press another key before switching
          into command mode

lib/readline/readline.c
        - since _rl_bind_if_unbound does the check of what's currently
          bound to the key sequence, the check in bind_arrow_keys_internal
          was redundant
        - bind_arrow_keys_internal now takes a Keymap argument and handles

          Cygwin

bashhist.c
        - split the history adding code into more pieces:
            check_history_control (char *line) checks LINE against the value
            of HISTCONTROL, returning 1 if LINE should be saved and 0 if not

            check_add_history (char *line) calls check_history_control and
            history_should_ignore (line) and saves the line with
            bash_add_history if the checks indicate that it should be saved

            maybe_add_history just calls check_add_history to set the value
            of first_line_saved

bashhist.h
        - extern declaration for check_add_history()

shell.c
        - don't call load_history() from the interactive shell startup
          code if history_lines_this_session is > 0, indicating that we've
          already saved some lines in the history and that we probably
          don't want to overwrite them

builtins/history.def
        - call check_add_history from push_history, so `history -s xx'
          works even when in a compound command whose first line has not
          been saved.  (Caveat:  in a compound command when the first
          line has been saved, the line supplied to history -s will become
          part of the compound command's history entry.  Of course, the
          delete_history call could remove the compound command from the
          history entirely)

bashline.c
        - use sh_makepath instead of xmalloc/sprintf in
          command_word_completion_function

lib/readline/complete.c
        - get_y_or_n now takes an int FOR_PAGER argument; caller changed
          If FOR_PAGER is non-zero, get_y_or_n returns appropriate values
          for a more-like pager:  `newline' or `return' return 2; `q' or
          `Q' return 0
        - there is now a mini internal more-like pager for displaying a
          list of completions that exceeds the screen height (new function
          _rl_internal_pager, called from rl_display_match_list)

bashline.c

stringlib.c

externs.h

subst.c
        - string_list_internal is no longer static

subst.h
        - new extern declaration for string_list_internal()

parse.y
        - new alist array of other tokens returned by read_token which are
          not reserved words in word_token_alist[]
        - reworked error reporting:  new functions print_offending_line,
          which prints the line containing the syntax error,
          error_token_from_token, which takes the current token and tries to
          figure out its textual representation, and error_token_from_text,
          which does the old job of finding the bad token by analyzing the
          text of shell_input_line at the current index
        - report_syntax_error now tries to figure out the token that caused
          the syntax error by first looking at current_token and falling
          back to the old method of textual analysis if that fails
        - report_syntax_error doesn't say the token resulting from the textual
          analysis of the input line is an `unexpected token'; it just
          says there is a `syntax error near xxx'
        - changed conditional command error reporting to use the value
          returned by error_token_from_token if it's not null instead of
          just using the token value in the message, since current_token
          ends up being set to -1, and the text of the message from
          report_syntax_error might not be exactly right
        - change parse_string_to_word_list to set current_token to the
          offending token returned by read_token before calling yyerror()
          to make the error reporting do the right thing

aclocal.m4

        - fix for snprintf/vsnprintf with length of 0 and string argument of
          0 with non-zero length

builtins/read.def
        - TMOUT is now the default timeout for `read' (and select) if set,
          like ksh93 when reading from the terminal
        - edit_line (called by read -e) now just does readline's filename
          completion by setting rl_attempted_completion_function to NULL,
          since e.g., doing command completion for the first word on the
          line wasn't really useful

execute_cmd.c
        - changed select_command to return failure status if select_query
          returns NULL, indicating that read_builtin returned
          EXECUTION_FAILURE

doc/{bash.1,bashref.texi}
        - documented new TMOUT behavior 
        - slight change to the description of the test `-ef' option

doc/bashref.texi

          the menu only if REPLY is set to NULL, if KSH_COMPATIBLE_SELECT
          is defined

config-top.h
        - define KSH_COMPATIBLE_SELECT, with a comment about its meaning

lib/readline/readline.c
        - change rl_insert_comment to toggle if given an explicit numeric
          argument:  if the first characters on the line don't specify a
          comment, insert one; if they do, delete the comment text

doc/bash.1, lib/readline/doc/{readline.3,rluser.texinfo}
        - documented new behavior of insert-comment with a numeric argument

lib/malloc/watch.c
        - new file, implements watchpoint functions

lib/malloc/watch.h
        - new file, define some `events' for watchpoints and extern function
          and variable declarations for watchpoint code

lib/malloc/imalloc.h
        - #define MALLOC_WATCH if MALLOC_DEBUG is defined
        - add __P define as in include/stdc.h if not already defined

lib/malloc/malloc.c
        - remove __P define, now in imalloc.h
        - include watch.h if MALLOC_WATCH is defined
        - added calls to _malloc_ckwatch in internal_malloc, internal_free,
          and internal_realloc

include/stdc.h
        - augment __P define to allow prototypes if PROTOTYPES is defined

lib/readline/rlstdc.h
        - augment PARAMS define to allow prototypes if PROTOTYPES is defined

lib/malloc/Makefile.in, Makefile.in
        necessary changes to include watch.c in libmalloc

lib/readline/readline.c
        - fix rl_delete_text to make sure that the starting position is >= 0
        - _rl_init_line_state (called by readline via readline_initialize)
          now sets rl_mark to 0
        - rl_get_{next,previous}_history set rl_mark to 0 if rl_point is at
          the end of the line and rl_end otherwise in emacs mode

lib/readline/kill.c
        - rl_yank_nth_arg_internal and rl_paste_clipboard now set the mark
          at point before calling rl_insert_text, like rl_yank
        - rl_kill_full_line now resets rl_mark to 0
        - rl_kill_line and rl_backward_kill_line now set rl_mark to the
          point after the kill in emacs mode
        - rl_kill_word and rl_backward_kill_word now set rl_mark to the
          point after the kill in emacs mode
        - rl_unix_word_rubout and rl_unix_line_discard now set rl_mark to
          the point after the kill in emacs mode

lib/readline/search.c
        - noninc_search saves and restores the mark, since it can be changed
          while reading the search string
        - noninc_dosearch sets the mark at the end of the line, making the
          region bound the `inserted' text since rl_point is set to 0
        - rl_history_search_internal sets the mark at the end of the line,
          for the same reason

lib/readline/isearch.c
        - rl_search_history now saves and restores the mark
        - if no matching lines are found at all when doing an isearch, leave
          point where it was instead of moving it to the end of the line

          declarations

lib/readline/{bind.c,readline.c,rlprivate.h}
        - new bindable variable, `byte-oriented', tracks value of

lib/readline/mbutil.c
        - new file, with multibyte char utility functions

lib/readline/{complete,display,readline,util,vi_mode}.c

                                   -----
lib/readline/complete.c
        - slight change to mark-directories code to avoid adding a slash if
          point is at the end of the line (rl_line_buffer[rl_point] == '\0')
          and the previous character was a slash
        - change printable_part to not return empty pathnames, which could
          happen when completing filenames and a filename with a trailing
          slash was passed as the argument.  If the portion following the
          trailing slash is NULL, ignore it and look for a previous slash.
          If there's no previous slash, just return the filename argument
        - new variable, rl_completion_mark_symlink_dirs, mirrors the value
          of (user-settable with a variable) _rl_complete_mark_symlink_dirs
          but may be modified by application-specific completion functions
          when appropriate (set in rl_complete_internal and rl_menu_complete)

lib/readline/readline.h
        - extern declaration for rl_completion_mark_symlink_dirs

pcomplete.c
        - if one of the actions is CA_DIRECTORY, set
          rl_completion_mark_symlink_dirs to indicate that we want the
          trailing slash (might have to relax this)

lib/readline/doc/rltech.texinfo
        - documented rl_completion_mark_symlink_dirs variable

lib/readline/doc/rluser.texinfo, doc/bash.1
        - documented the fact that `complete -d' and `complete -o dirnames'
          force readline to append a slash to symlinks to directories

builtins/enable.def
        - changed enable_shell_builtin to disallow enabling disabled
          builtins in a restricted shell

doc/{bash.1,bashref.texi}
        - documented new enable behavior in restricted shells

doc/Makefile.in
        - new rule to make an `RBASH' file documenting the restrictions
          imposed by a restricted shell

expr.c
        - broke the code that evaluates variables and returns results out
          of readtok() into a new function: expr_streval()
        - expr_streval() now performs the standard unset variable error
          behavior if `set -u' has been executed and it's asked to look
          up an unset variable
        - broke the code that frees up the expression context stack into
          a new function: expr_unwind()

variables.c
        - fixed bind_int_variable so it handles array element assignment,
          so expressions like `b[7]++' and `b[0] = 42' work right
        - new function, get_variable_value, returns the string value of
          the SHELL_VAR * passed as an argument
        - get_string_value now calls get_variable_value with a non-null
          result from find_variable

          not defined and NEED_STRFTIME_DECL is

lib/tilde/tilde.h
        - header files should not include <config.h>

parse.y
        - replace code in decode_prompt_string that chops up value returned
          by ctime(3) with calls to strftime -- as a result, the expansion
          of \@ has changed slightly (since it depends on the locale)
        - added new \D{format} prompt string escape; `format' is passed to
          strftime(3).  Empty format is the same as `%X' (locale-specific
          representation of the current time)
        - combined cases for '\\', '\a', '\e', and '\r' in same case branch
          in decode_prompt_string

doc/{bash.1,bashref.texi}
        - documented new \D{format} prompt string expansion

builtins/printf.def
        - use ISO C PRIdMAX instead of INTMAX_CONV
        - pass length of format modifiers to mklong instead of computing it
          with strlen()

lib/sh/{fmtulong,fmtullong}.c
        - changes from Paul Eggert to make more general

arrayfunc.c
        - when converting a variable to an array, make sure to unset the
          dynamic_value and assign_func members of the struct variable,
          since they're not valid anymore

                                   12/27

        - include shmbutil.h

{braces,make_cmd}.c
        - changes for multibyte characters

builtins/printf.def
        - changes from Paul Eggert to just use intmax_t everywhere an
          int/long/quad is needed and print with "%ld" if the number
          fits in a long and %PRIdMAX otherwise
        - remove getlong, getulong, getllong, getullong, since they're
          no longer needed
        - use a new type `floatmax_t' to print floating point numbers, the
          widest-available floating point type (like `intmax_t'); new
          function `getfloatmax' that calls strtold or strtod as appropriate
        - remove getdouble, getldouble, since they're no longer needed

lib/sh/fmtumax.c

bashtypes.h

externs.h

          before looking at the interpreter to find out why the execve()
          failed (avoids misleading error message)

lib/glob/glob.c

builtins/set.def
        - make -o options into one struct, instead of separate structs for
          option names corresponding to flags and non-flag option names.
          This has the side effect of sorting the option names in output

lib/glob/glob.c
        - new function, mbskipname(), multibyte char version of skipname()
        - removed all #ifndef SHELL code, this will never be used outside

          the appropriate value to pass to rl_complete_internal depending on

          any of the temporary environments if variable_context > 0 (meaning

variables.c
        - tentative change to lookup order in find_variable_internal so that

          function_env when executing a shell function
        - change make_local_variable to handle making a local variable when
          a variable with the same name already appears in one of the
          temporary environments
        - broke the body of make_var_array out into a new function:
                static char **make_env_array_from_var_list (SHELL_VAR **vars)
        - new function, make_var_array_internal, takes a hash table to look
          in and a pointer to a mapping function and returns a char **
          environment-style list
        - make_var_array now just calls make_var_array_internal
        - new mapping function, local_and_exported, returns all local variables
          in the current variable context with the export attribute set
        - new function, make_local_export_array, returns an environment-style
          char ** array of exported local variables in current context
        - change environment creation order in maybe_make_export_env to
          add variables to the environment in opposite order that
          find_variable_internal uses.  This means that local variables in
          shell functions override variables with the same name in the
          function_env
        - change make_local_variable to set the initial value of the
          variable it creates to NULL to make the `is set' and `is null'
          tests that the expansion code does work right
        - change make_local_variable to inherit the value of a variable with
          the same name from the temporary enviroment

        - find_pipeline takes a third argument: an int *.  If it looks in
          the jobs list to find the pid, and the arg is non-null, it passes
          the job index back to the caller.  Used to avoid calls to

          to propagate the value out of the temporary environment up the
          (for now implicit) chain of variable scopes when the containing
          temporary environment is deleted

variables.c

builtins/getopt.c
        - don't defer incrementing of OPTIND when an invalid option is
          encountered until the next call to sh_getopt() -- what if OPTIND
          is reset before that next call?  This means that OPTIND is always
          incremented to the next option to be handled when an option is
          returned, whether it's valid or not.  This is what POSIX-2002
          says to do.

syntax.h
        - new #define, CSUBSTOP

mksyntax.c
        - add "-=?+" with value CSUBSTOP to the syntax table.  These are the
          valid expansion operators OP in ${param[:]OPword}

subst.c
        - use table lookup for CSUBSTOP in VALID_PARAM_EXPAND_CHAR
        - new flags for the string extraction functions:  EX_NOALLOC.  This
          indicates that the functions are being used only to skip over
          strings and the result won't be used, so the substring shouldn't
          be allocated, copied, and freed
        - new flag for string_extract:  EX_VARNAME.  This serves the same
          purpose as the old `varname' parameter.  parameter_brace_expand()
          changed appropriately
        - extract_delimited_string and extract_dollar_brace_string now take
          an additional `flags' argument, which may include EX_NOALLOC
        - changed callers of extract_delimited_string and
          extract_dollar_brace_string appropriately
        - string_extract now understands EX_NOALLOC; callers changed

variables.[ch]
        - moved to a symbol organization inspired by lcc.  The basic structure
          is no longer a HASH_TABLE, but a VAR_CONTEXT, which includes a hash
          table as one of its members.  VAR_CONTEXTs are linked together to do
          variable scoping.  One nice thing about this is that the entire
          symbol table doesn't need to be searched at function scope exit to
          remove local variables.  Fixes problems with only one instance of
          builtin_env and function_env, even though it really is a stack
        - shell_variables is now a VAR_CONTEXT *, with a global_variables
          variable that points to the bottom of the stack for fast access
        - function-scope local variables (assignments specified on the command
          line before a function call) and function-local variables (declared
          with the `local' builtin) have been unified in the same variable
          context, replacing function_env
        - assignment statements preceding the `.' and `eval' builtins are now
          a separate variable scope VAR_CONTEXT, replacing builtin_env
        - temporary_env (a HASH_TABLE) is now the only separate environment
        - changes to export environment creation, variable binding, variable
          lookup, local variable propagation all changed to work with the
          new symbol table/scope structure
        - a SHELL_VAR no longer has a `prev_context' member; it's not needed

execute_cmd.c
        - changes to push_context calls to include any temporary variables in
          temporary_env; pop_context takes care of propagating any temporary
          variables if necessary
        - calls to push_scope if `eval' or `.' is called with a list of
          preceding variable assignments, and pop_scope called at end of
          builtin's execution.  pop_scope takes care of merging temporary
          variables into the shell environment when appropriate

builtins/{setattr,declare}.def
        - changes to account for variable assignments preceding `local',
          `export', `readonly', `declare', etc. to work with the new
          variable scoping implementation

shell.c
        - since shell_variables is now a VAR_CONTEXT, call
          delete_all_contexts() when the shell is reinitializing instead of
          delete_all_variables()

builtins/common.c

          for the `auto_resume' stuff and get_job_spec()

builtins/common.h
        - new set of #defined constants for flags argument to

{dispose_cmd,copy_cmd,make_cmd,print_cmd}.c

redir.c

          second argument
        - new function, write_here_string, expands a here string and writes it
          to the here document file descriptor
        - here_document_to_fd calls write_here_string for r_reading_string
          operator

expr.c
        - make expr_streval understand that variables with the `invisible'
          attribute are really unset, and accessing such a variable when
          `set -u' is set should be an error

variables.h
        - new accessor macros: var_isset(var) and var_isnull(var), test

{eval,subst,variables}.c, builtins/{declare,setattr}.def
        - be more consistent about using value_cell(var) instead of

        - word_list_split() now calls getifs() and passes the result to
          each call to word_split() as its second arg

          waiting children
        - cleanup_dead_jobs now just sets and clears queue_sigchld instead of
          blocking and unblocking SIGCHLD; it calls waitchld at the end if
          `sigchld' is non-zero, but that's not really necessary
        - in setjstatus, only call xrealloc if `statsize' is less than the

        - reinitialize_signals is no more; initialize_signals takes an
          argument saying whether or not we are reinitializing

builtins/exec.def
        - reinitialize_signals() -> initialize_signals(1)

test.c
        - fix filecomp() to work right when one file has a non-positive
          timestamp and the other file does not exist

doc/{bash.1,bashref.texi}
        - document what happens for test's -nt and -ot operators when one
          file operand exists and the other does not

jobs.c
        - if we haven't messed with SIGTTOU, just manipulate queue_sigchld
          in notify_of_job_status instead of calling sigprocmask()
        - list_one_job now calls pretty_print_job directly instead of going
          through print_job
        - pretty_print_job now must be called with SIGCHLD blocked or held
          instead of blocking SIGCHLD itself
        - changed start_job so that it doesn't call UNBLOCK_CHILD and then
          immediately call BLOCK_CHILD again (explicitly or via last_pid()),
          call find_last_pid instead of last_pid and then UNBLOCK_CHILD
        - changed wait_for_job the same way
        - find_last_pid now takes a second argument: block; uses BLOCK_CHILD
          if `block' is 1, not otherwise.  Changed existing calls:
                find_last_pid(j) -> find_last_pid(j, 0)
                last_pid(j) -> find_last_pid(j, 1)
          `last_pid()' is now gone
        - rewrote wait_for_background_pids(); it was a little strange
        
copy_cmd.c
        - copy_if_command: don't copy null false_case commands

subst.c
        - in get_word_from_string and list_string, just check for " \t\n"

          isifs() instead of issep(), since they're never called with
          separators != $IFS
        - change issep() to call isifs if separators is longer than one
          character, since it's never called with anything but "", " ",
          or $IFS

lib/readline/terminal.c
        - if an application is using a custom redisplay function,
          rl_resize_terminal just calls rl_forced_update_display to tell

          _rl_redisplay_after_sigwinch

lib/readline/readline.c
        - change readline_internal_setup() so the change to vi insertion mode
          happens even if readline_echoing_p is 0
        - don't print the prompt to rl_outstream in readline_internal_setup

parse.y

bashline.c

bashline.c
        - bash_directory_completion_hook calls expand_prompt_string instead
          of expand_string (it does the right thing).  This keeps expansion
          errors from causing a longjmp, which shouldn't happen because of
          completion
        - command_subst_completion_function was augmented very slightly to
          do filename completion on a non-command-word in a command
          substitution
        - command_subst_completion_function now skips over the lcd that
          rl_completion_matches puts in matches[0] if there is more than
          one possible completion

          Functions with this attribute will inherit the DEBUG trap.
          Currently ignored for variables

builtins/declare.def
        - new `-t' option to declare/typeset toggle the `att_trace' attribute

shell.c

          for `-', like other shells

          parse_shell_options because the `-l' option might set it

doc/{bash.1,bashref.texi}

array.c

        - array_walk is now compiled in by default
        - array_to_assignment_string now takes a second argument: int quoted.
          If non-zero, the result is single-quoted before being returned
        - quoted_array_assignment_string has been removed

array.[ch]
        - renamed most of the array functions so that all have an array_
          prefix and are more systematically named
        - array_slice now preserves the indicies from the original array
        - change array_to_assign to use a static buffer for expanding the
          array indices, instead of malloc/free

{arrayfunc,subst,variables}.c, builtins/read.def
        - changed calls to various array functions to use new names

lib/sh/stringvec.c, externs.h
        - renamed all of the functions to have a strvec_ prefix and to have
          a more sensible name scheme
        - strvec_search's arguments are now supplied in reverse order, so
          the char **array is first, like the other functions

examples/bashdb/bashdb

          version in bash-2.04 by Gary Vaughan (the old debugger still
          appears in examples/obashdb).  This version has a more gdb-like
          command set

examples/bashdb/bashdb.el
        - new emacs bashdb debugger mode from Masatake YAMATO <jet@gyve.org>

execute_cmd.c
        - don't make $LINENO relative to function start unless the shell is
          currently interactive -- this is what ksh93 does and what I
          believe to be the intent of POSIX.2 (this required changing some
          of the test checks because the output has changed)
        - run the debug trap for each command in an arithmetic for expression,

hashlib.c

array.c
        - fixed array_walk to return if the item function returns < 0, like
          hash_walk

lib/sh/stringlist.c, externs.h
        - new function: strlist_walk, takes a stringlist and a pointer to an
          item func.  Like other _walk funcs, if item func returns < 0 the
          walk is cancelled
        - new function: strlist_flush, frees items in the contained list
          with strvec_flush
        - renamed functions to have a strlist_ prefix and be more systematic

pcomplib.c,pcomplete.h
        - removed redundant `progcomp_initialized' variable
        - renamed functions to have `progcomp_' or `compspec_' prefixes
          like the hash library

{bashline,pcomplete}.c,builtins/complete.def
        - fixed calls to stringlist functions to use new names

lib/sh/stringvec.c
        - changed name of second argument to strvec_from_word_list from `copy'
          to `alloc' so the use of `copy' between strvec_from_word_list and
          strvec_to_word_list isn't as confusing
        - changed name and sense of second argument to
          strvec_to_word_list from `copy' to `alloc' for the same reason --
          now both functions agree on semantics of second argument

lib/sh/stringlist.c

        - regularized error messages to `bind: object: error string' like
          other error messages

builtins.h
        - the `short_doc' member of a `struct builtin' is now of type
          `const char *'

          `unbound variable' message
        - new function, err_readonly(s), calls report_error with standard
          `readonly variable' message

{arrayfunc,subst}.c
        - call err_badarraysub where appropriate

{expr,subst}.c
        - call err_unboundvar where appropriate

{arrayfunc,variables}.c
        - call err_readonly where appropriate

shell.c
        - changed text of bad option error messages to be the same as that
          printed for builtin errors

builtins/common.c
        - changed sh_invalidopt to print the invalid option before the rest
          of the error message (required some tests to be modified)
        - new function, sh_readonly, calls builtin_error with standard
          `readonly variable' message

variables.c,builtins/declare.def
        - call sh_readonly where appropriate

lib/sh/stringvec.c
        - added strvec_remove (sv, s), removes S from SV and shuffles rest of
          elements down 1

lib/sh/stringlist.c
        - added strlist_remove(sl, s), just calls strvec_remove on the
          component list

externs.h
        - new extern declarations for strvec_remove and strlist_remove
        - fixed extern declaration for strvec_search; the arguments were
          reversed (unimportant, it's not compiled into the shell)

subst.c
        - change param_expand to call quote_escapes on values retrieved when
          expanding the positional parameters
        - change parameter_brace_expand_word to quote escapes on values
          retrieved when expanding the positional parameters
        - fix parameter_brace_substring to quote escape characters on unquoted
          substrings extracted from variable values (needed to separate case
          VT_VARIABLE from VT_ARRAYMEMBER for this, since, because
          get_var_and_type calls array_value for VT_ARRAYMEMBER, we need to
          skip over quoted characters in an already-appropriately-quoted
          string to find the substring we want)
        - fix parameter_brace_substring to quote escape characters in the
          value returned by pos_params when expanding subsets of the
          positional parameters and not within double quotes (in which case
          pos_params() quotes the string for us)
        - fix parameter_brace_substring to quote escape characters in the
          value returned by array_subrange when expanding subsets of an
          array and not within double quotes (in which case
          array_subrange() quotes the string for us)
        - new function, quoted_strlen(s), does strlen(s) while skipping over
          characters quoted with CTLESC (#ifdef INCLUDE_UNUSED, since it's
          not used yet)
        - changed pos_params() so it always returns a list whose members are
          quoted strings if (quoted&(Q_HERE_DOCUMENT|Q_DOUBLE_QUOTES)) != 0

arrayfunc.c
        - fix array_value to consistently call quote_escapes, even when a
          non-array variable is being subscripted with element 0, in which
          case we return the variable value

lib/sh/strtrans.c
        - make the for_echo parameter to ansicstr a `flags' parameter that
          has its old `for echo' meaning if flags&1 is non-zero (which is
          consistent with the old code)
        - Added code to the `flags' parameter to ansicstr so that if flags&2
          is non-zero, CTLESC and CTLNUL are escaped with CTLESC in the
          expanded string
        - change ansiexpand() to call ansicstr with a `flags' parameter of 2

arrayfunc.c
        - changed array_value_internal to take an additional `int *'
          parameter, in which is returned the type of array indexing
          performed (array[@] vs. array or array[index])
        - changed array_value and get_array_value to take a corresponding
          extra parameter and pass it to array_value_internal
        - changed array_value_internal to no longer return newly-allocated
          memory or quote CTLESC and CTLNUL in the returned string if
          `simple' array indexing (subscript not `@' or `*') is being
          performed.  This makes it more like a variable lookup

arrayfunc.h
        - changed prototypes for array_value and get_array_value

expr.c
        - added new parameter to call to get_array_value in expr_streval
        - don't need to free memory returned by get_array_value any more

subst.c
        - quote_escapes now works with multibyte characters
        - dequote_string now works with multibyte characters
        - dequote_escapes is now needed, so it's compiled in, and it
          now works with multibyte characters
        - remove_quoted_escapes now just calls dequote_escapes and copies the
          result over the argument string
        - remove_quoted_nulls now returns its char * argument, parallels
          remove_quoted_escapes
        - parameter_brace_expand_word now passes the new argument to
          array_value and quotes CTLESC and CTLNUL in the result if it's a
          `simple' array expansion by calling quote_escapes
        - get_var_and_type now returns VT_ARRAYMEMBER for references like
          ${array} where `array' is an array variable (just like ${array[0]}).
          Documented (in comment) that a VT_VARIABLE return value means that
          quote_escapes has been called at some point
        - changed callers of get_var_and_type to no longer free value if
          VT_ARRAYMEMBER is returned as type
        - changed parameter_brace_substring and parameter_brace_patsub to
          call dequote_escapes on the value from get_var_and_type if the
          type is VT_VARIABLE, since the substring and pattern substitution
          code doesn't understand CTLESC quoting
        - parameter_brace_substring no longer needs to call quoted_substring
          for the VT_ARRAYMEMBER case
        - changed parameter_brace_patsub to call quote_escapes on the result
          of pat_subst for the VT_VARIABLE and VT_ARRAYMEMBER cases, and to
          quote the returned string in the VT_ARRAYVAR and VT_POSPARAMS cases
          if the `MATCH_QUOTED' flag isn't set (if it is, the pattern
          substitution functions perform any necessary quoting)
        - quoted_substring is no longer used; it's now #ifdef INCLUDE_UNUSED

lib/malloc/mstats.h
        - new member in _malstats: u_bits32_t bytesreq, the total number of
          bytes requested by the caller via calls to malloc() and realloc()

lib/malloc/stats.c
        - print bytesreq member in _print_malloc_stats
        - don't print statistics for buckets for which nmal == 0 (no mallocs)

lib/malloc/malloc.c
        - modified internal_malloc, internal_realloc to keep running total of
          number of bytes requested by calling application

subst.[ch]

subst.c
        - moved code from parameter_brace_expand into a new function that
          dispatches for pattern substitution: parameter_brace_remove_pattern
        - changed structure of parameter_brace_remove_pattern to be like
          parameter_brace_patsub and its ilk:  call get_var_and_type to
          isolate the variable name, move the pattern isolation code out of
          the various *_remove_pattern functions into
          parameter_brace_remove_pattern and pass the results to the various
          functions, use a switch on the return value from get_var_and_type
          to decide which function to call, regularized the arguments to the
          separate pattern removal functions
        - parameter_brace_remove_pattern now properly quotes escape chars in
          the returned value
        - changed get_var_and_type to call dequote_escapes on the `value'
          parameter for case VT_VARIABLE and return the result in *valp,
          so the calling functions don't have to do it themselves; changed
          callers appropriately
        - fixed getpattern() where it broke posix compliance:  if you enclose
          a pattern removal spec in double quotes, the outer double quotes
          have no effect on the pattern (POSIX.1-200x 2.6.2).  This uncovered
          a bug in the test suite (!)

pathexp.c
        - fixed a problem with quote_string_for_globbing where it would change
          consecutive CTLESC chars all to \ instead of changing every other
          quoted char

lib/glob/smatch.c

          strcoll/strcmp/strlen and their wide-character equivalents, added
          appropriate casts
        - static arrays in single-byte version of rangecmp() are `char', not
          `unsigned char', so compilers don't complain about calls to strcoll

lib/glob/sm_loop.c
        - casts for `XCHAR' and `XCHAR *' arguments to libc functions
        - use prototype declaration for BRACKMATCH if `PROTOTYPES' is defined
          to avoid problems with type promotion (unsigned char -> int)

lib/glob/collsyms.h
        - `name' member of struct _COLLSYM is now of type `XCHAR *', since

          readline command that may appear in ~/.inputrc may be supplied as
          one of the non-option arguments to `bind'

builtins/mkbuiltins.c
        - added support for `-H' option, which means to write long documentation
          for each builtin to a separate file in the `helpfiles' directory

builtins/Makefile.in
        - new target `helpdoc', just creates long doc files in helpfiles
          directory

lib/sh/zcatfd.c

builtins/{common.c,{builtin,eval,exit,fg_bg,let,printf,pushd,return,source,wait}.def

{configure,Makefile}.in, builtins/{Makefile.in,help.def,mkbuiltins.c}

          moves the `long' help text to separate help files, installed by
          default into ${datadir}/bash, one file per builtin.  Off by
          default -- it saves 47K, but it's only 47K, and it's in the text
          segment

flags.c
        - build internal_getopt() option string argument from flags array at
          runtime in shell.c

shell.c
        - new variable to control writing malloc stats at exit:
          malloc_trace_at_exit, 0 by default

lib/malloc/malloc.c
        - heavily updated:
                o partial page allocated on first call to malloc to make
                  subsequent sbrks page-aligned no longer wasted
                o begin and end range guards are now the same value: the chunk
                  requested
                o coalescing code was changed to attempt to coalesce first two
                  adjacent blocks on the free list; enabled by default
                o blocks of size 32 are now candidates for larger block
                  splitting, since 32 is the most popular size
                o blocks of size 32 are now candidates for smaller block
                  coalescing
                o the IN_BUCKET check was changed to just make sure that the
                  size isn't too big for the bucket, since the `busy block'
                  checking code may increase the bucket by one or more,
                  meaning that the old check would fail and cause a panic when
                  a chunk allocated in such a way was freed
                o bin sizes are now precomputed and looked up in an array
                  rather than being computed at runtime
                o moved the _mstats declaration here to avoid the stats code
                  being linked in even when no stats functions were called
                  (only matters if MALLOC_DEBUG is defined)
                o malloc now keeps track of the address of the top of the heap
                  and will return large chunks to the system with calls to
                  sbrk with a negative argument when freeing the top chunk.
                  Two thresholds:  LESSCORE_FRC means to unconditionally return
                  memory to the system; LESSCORE_MIN means to return memory if
                  there's at least one block already on the free list

lib/malloc/mstats.h
        - stats struct now keeps track of number of block coalesces by bin,
          and the number of times memory was returned to the system by bin

lib/malloc/stats.c
        - trace_malloc_stats now takes a second argument: the name of the file
          to write to.  The first `%p' in the template file name is replaced
          by the pid

configure.in, config.h.in

bashline.c
        - punt immediately from bash_servicename_completion_function if
          HAVE_GETSERVENT is not defined (cygwin seems to not define it)
        - include "input.h" for extern save_token_state() and
          restore_token_state() declarations
        - change bash_execute_unix_command to call parse_and_execute with
          SEVAL_NOHIST flag so the command doesn't get saved on the history
          list
        - change bash_execute_unix_command to save and restore the current
          command line count and the token state (last_read_token, etc.).
          Everything else is saved by either parse_and_execute directly or
          the call it makes to push_stream().  The shell_input_line stuff
          doesn't need to be saved and restored; it's not computed until
          readline() returns

          the bug where an input redirection to a builtin inside a script
          which is being read from stdin causes the already-read-and-buffered
          part of the script to be thrown away, e.g.:

                bash < x1

          bug reported by jg@cs.tu-berlin.de on 17 July 2002.  Should be a way
          to check whether or not the current fd 0 at the time of the call has
          not been redirected, like in the bug report.  Also might eventually
          want to throw in a sync_buffered_stream if bash is reading input
          from fd 0 in a non-interactive shell into a buffered stream, so the
          stream is sync'd -- might be necessary for some uses

lib/readline/text.c
        - fixes to overwrite mode from jimmy@is-vn.bg:
                o in _rl_overwrite_char, do the overwrite mode self-insert
                  as one group, even when overwriting more than 1 char
                o in _rl_overwrite_char, do the insert before the delete so
                  that an undo positions the cursor on the character restored,
                  not to the right of it
                o in _rl_overwrite_rubout, don't do rl_insert_char(' ') unless
                  rl_point < rl_end.  Since overwrite-mode self-insert acts as
                  in insert-mode when at eol, make rubout behave like
                  insert-mode rubout

bashline.c

        - change history_expand_line_internal and cleanup_expansion_error to

          locales

lib/readline/readline.h

lib/readline/rltty.h

lib/readline/rltty.c
        - set the RL_STATE_TTYCSAVED after save_tty_chars is called

          everything rl_tty_set_default_bindings() messes with back to
          rl_insert, so rl_tty_set_default_bindings can be called again with

        - new function that does the bulk of the work for
          rltty_set_default_bindings:  _rl_bind_tty_special_chars()
        - change prepare_terminal_settings so that it can track changes to the
          terminal special chars made by stty(1):  unset the bindings with
          rl_tty_unset_default_bindings before calling save_tty_chars, and
          _rl_tty_set_default_bindings after, with the new values from
          get_tty_settings().  This implements a long-standing request, most
          recently made by Tim Waugh of Red Hat.

lib/readline/readline.h

        - keep a stack of line numbers where case, select, and for commands
          start, with a maximum nesting level of 128; increment when reading
          word after `for', `select' or `case' in read_token_word; decrement
          in grammar actions after parsing a complete for, arith_for, select,
          or case command
        - create for, case, arith_for, and select commands with an extra
          line number (word_lineno[word_top]) argument

make_cmd.c
        - make_for_or_select, make_for_command, make_case_command, and
          make_select_command all take an extra `line_number' argument

make_cmd.h
        - corresponding changes to extern declarations for those functions

{execute_cmd,shell,variables}.c
        - follow each call to remember_args with a call to push_args or
          pop_args to manage the BASH_ARGV and BASH_ARGC arrays.  Only set
          when the shell is started to run shell script or runs a shell
          function.  Doesn't handle `set' or `shift' yet, nor `source'.

execute_cmd.c
        - keep track of the level of subshells with a new variable, manipulated
          in execute_in_subshell
        - set currently_executing_command in execute_command_internal(),
          even if we're running a trap
        - better line number management when executing simple commands,
          conditional commands, for commands in execute_command_internal()
          and the various functions that implement the commands
          (execute_cond_command, execute_for_command, execute_etc.)

variables.c
        - new dynamic variable BASH_SUBSHELL, with new get_subshell and
          assign_subshell functions to manipulate it
        - new functions push_args (WORD_LIST *list) and pop_args (void) to
          manage the BASH_ARGC and BASH_ARGV dynamic array variables

variables.h
        - new extern declarations for push_args and pop_args

builtins/evalfile.c
        - in _evalfile, do appropriate things to the FUNCNAME, BASH_ARGV,
          BASH_ARGC, BASH_SOURCE, and BASH_LINENO variables

support/mksignames.c
        - add another fake signal for `trap'; make NSIG+2 == `RETURN'

trap.c
        - _run_trap_internal now returns an int:  the exit value of the command
          run as the result of the trap
        - run_debug_trap now returns an int: the exit value of the command
          run as the result of the trap
        - RETURN is a new special trap
        - new function: set_return_trap(char *command) interface for the rest
          of the shell, like set_{debug,error}_trap
        - new function: run_return_trap()
        - command substitution and other child processes don't inherit the
          return trap

trap.h
        - new extern declaration for set_return_trap() and run_return_trap
        - new defines for RETURN_TRAP; increment BASH_NSIG
        - change extern declaration for run_debug_trap() since it now returns
          an int

shell.c
        - new invocation long option:  --debugger, turns on debugging and
          sets internal `debugging_mode' variable

execute_cmd.c
        - new code to save return trap when executing a shell function, so
          shell functions don't inherit it
        - run debug trap before binding the variable and running the action
          list in a `for' command
        - run debug trap before binding the selection variable and running
          the query in a `select' command
        - run debug trap before running matcher in a `case' command

builtins/set.def
        - new `set -o functrace' (set -T), causes DEBUG trap to be inherited
          by shell functions
        - new `set -o errtrace' (set -E), causes ERR trap to be inherited
          by shell functions

flags.c
        - new flags -E and -T, control error_trace_mode and
          function_trace_mode respectively

flags.h
        - new extern declarations for error_trace_mode and function_trace_mode

          substituted by configure

aclocal.m4
        - added AM_PATH_LISPDIR for debugger

configure.in
        - added some variables: `bashvers', `relstatus' to use info in more
          than one place
        - call AM_PATH_LISPDIR
        - new option:  --enable-debugger, sets DEBUGGER cpp option
        - new option with AC_ARG_VAR:  DEBUGGER_START_FILE
        - make `pathnames.h' a file generated by configure

Makefile.in

        - added extra line number and source file name to `declare -F' output
          if `--debugger' is used at startup

builtins/evalfile.c
        - call run_return_trap from source_file before returning the result

execute_cmd.c
        - call run_return_trap in execute_function before restoring the old

        - arrange to save and restore DEBUG traps when sourcing files if
          function_trace_mode (set -o functrace) is not set

print_cmd.c
        - broke print_for_command, print_select_command, print_case_command
          into two functions each:  one to print the `header' and one for
          the body
        - print_cond_command is no longer static
        - print_arith_command now takes a WORD_LIST *, since it doesn't
          actually do anything with the ARITH_COM it's passed except print
          the enclosed WORD_LIST
        - print_arith_command is no longer static

lib/glob/glob.c

subst.c
        - check whether shell_glob_filename returns NULL in
          glob_expand_word_list
        - change parameter_brace_expand_rhs to handle cases like
          ${a[2]:=value} by properly creating the array element instead of a
          variable named `a[2]' (reported by <opengeometry@yahoo.ca>)

variables.c
        - change bind_int_variable to use valid_array_reference instead
          of looking for `[' 

lib/readline/vi_mode.c
        - check for `a' in _rl_vi_done_inserting so the text inserted by an
          `a' command can be reinserted with a `.'

lib/readline/readline.c
        - when entering vi insertion mode in readline_internal_setup(), make
          sure that _rl_vi_last_key_before_insert is set to `i' so that undo
          groups and redo work better (reported by <opengeometry@yahoo.ca>)

lib/glob/sm_loop.c
        - handle ?(...) in a pattern immediately following a `*', instead of

execute_cmd.c
        - new variable, the_printed_command_except_trap, saves the command
          being executed before a trap is executed, for the debugger

trap.c
        - if in debugging mode, let command substitutions and other child
          processes inherit the DEBUG and ERR traps if the `functrace'
          (which is really a bad name, given this semantic) or `errtrace'
          options, respectively, have been set

shell.c
        - local_pending_command renamed to command_execution_string; no longer
          static

variables.c

          currently executing, or the one that caused a trap to execute
          (mapped to the_printed_command_except_trap)
        - new variable, BASH_EXECUTION_STRING, set to the argument to the

          execute_select_command, execute_arith_command, execute_cond_command,
          execute_simple_command to implement new DEBUG trap semantics
          for the debugger: if the DEBUG trap commands return a non-zero
          status and debugging_mode is non-zero, we skip the command to be
          executed

trap.c
        - change run_debug_trap for the debugger: if we're in the debugger
          and the DEBUG trap returns 2 while we're in a function or sourced
          script, we force a `return'

shell.c
        - new function, start_debugger(), that sources the debugger start file
          and turns the debugger on

builtins/shopt.def
        - new settable option, `extdebug', turns on debugging_mode, as if
          --debugger had been supplied at invocation (but does not source
          debugger startup file)

trap.c
        - make sure that run_exit_trap arranges for `returns' to come back
          there, too, so a `return' executed by an `exit' invoked within a
          shell function behaves correctly

support/shobj-conf
        - change darwin/MacOS X stanza based on advice from mac os x developers

lib/sh/mailstat.c
        - set the atime member of the synthesized stat struct to 0 if `cur/'

builtins/caller.def
        - new builtin to provide a call stack for the debugger

builtins/evalfile.c

          If included in flags arg, it means to not manipulate the BASH_ARGV
          and BASH_ARGC arrays

builtins/common.h
        - change prototype for source_file()

builtins/source.def

          subshell

          set -x is enabled
        - add spaces after `((' and before `))' in xtrace_print_arith_command

externs.h

        - added description of `-o plusdirs' to complete/compgen (thanks,
          Arnold)

parse.y
        - new parser_state flag, PST_ASSIGNOK, if set indicates we're parsing
          arguments to a builtin that accepts assignment statement arguments
        - turn on PST_ASSIGNOK in read_token_word when appropriate
        - turn off PST_ASSIGNOK in read_token when appropriate
        - don't attempt to parse a compound assignment specially unless we're
          in a position where an assignment statement is acceptable, or
          PST_ASSIGNOK is set

                                   ----
variables.c
        - make BASH_ARGC, BASH_ARGV, BASH_LINENO, and BASH_SOURCE
          non-unsettable, since the shell uses those values internally

expr.c
        - make exponentiation right-associative, as is apparently correct

                                   9/16
                                   ----
arrayfunc.c

          recreation if the converted variable was exported

                                   9/17
                                   ----
braces.c
        - mark ${ as introducing an additional level of braces only if it's
          not in a quoted string -- quoted strings are handled before brace
          matching is done

parse.y
        - fixed an obscure problem in history_delimiting_chars where the `in'
          in a case statement could have a semicolon added after it, if the
          `case word' was on a previous line

support/config.guess
        - support for newest versions of tandem non-stop kernel

lib/readline/display.c
        - in compute_lcd_of_matches, explicitly cast `text' to `char *' before
          passing it to rl_filename_dequoting_function

lib/readline/terminal.c
        - bind the key sequence sent by the keypad `delete' key to delete-char
          (same as ^D in emacs mode)

builtins/ulimit.def
        - in print_all_limits, don't print anything if get_limit returns
          -1/EINVAL, indicating that the kernel doesn't support that particular
          limit
        - add -i (max number of pending signals), -q (max size of posix msg
          queues), -x (max number of file locks) for systems (Linux) that
          support them

doc/{bash.1,bashref.texi}
        - fix description of correspondence between FUNCNAME, BASH_LINENO,
          and BASH_SOURCE indices in description of BASH_LINENO

                                   9/18
                                   ----
lib/sh/shquote.c
        - don't quote CTLESC and CTLNUL with CTLESC in sh_backslash_quote, as
          long as the resultant string never gets sent to the word expansion
          functions without going through the shell parser

externs.h
        - add extern declarations for strnlen and strpbkrk from lib/sh

subst.[ch]
        - changes to handle case where IFS consists of multibyte characters.
          Changed: string_extract_verbatim, split_at_delims,
          string_list_dollar_star, string_list_dollar_at, list_string,
          get_word_from_string, setifs

mailcheck.c
        - change file_mod_date_changed to reset the cached mail file data if
          the file size drops to zero

lib/readline/complete.c
        - change append_to_match so that a non-zero value for
          rl_completion_suppress_append will cause no `/' to be appended to a
          directory name

bashline.c
        - experimental change to suppress appending a slash for a completed
          filename that is found in PATH as well as a directory in the current
          directory under certain circumstances:  a single instance found in
          $PATH when `.' is not in $PATH, and multiple instances found in the
          $PATH, even when `.' is in the $PATH

                                   ----
command.h
        - new word flag: W_ASSIGNRHS, means word is rhs of assignment statement
        - new word flag: W_NOTILDE, means word is not to be tilde expanded
        - new word flag (internal): W_ITILDE, means the next character is a
          tilde that should be expanded

general.c
        - new set of tilde suffixes for use when parsing the RHS of an
          assignment statement and =~ should not be subject to tilde expansion
        - if ASSIGN_P argument to bash_tilde_expand is 2, use tilde prefixes
          for parsing RHS of assignment statement

general.[ch]
        - new function bash_tilde_find_word, drop-in replacement for
          tilde_find_word

subst.c
        - call bash_tilde_expand with secord argument of 2 when expanding rhs
          of an assignment statement, so tildes after second and subsequent
          `=' in an assignment are not expanded
        - new function, expand_string_assignment, to expand the rhs of an
          assignment statement
        - add `~' to EXP_CHAR, the characters that will cause the word
          expansion functions to be called
        - move tilde expansion into expand_word_internal instead of many
          different calls to bash_tilde_expand scattered across different
          functions.  NOTE:  This means that double quotes surrounding a
          {paramOPword} expansion will cause tilde expansion to NOT be
          performed on `word'.  I think this is right, what POSIX specifies,
          and consistent with the behavior of other characters in the rhs

execute_cmd.c
        - take out calls to bash_tilde_expand before calling word expansion
          functions

                                   9/26
                                   ----

          failure in execute_pipeline

                                   ----
variables.c
        - change get_bash_command to deal with the_printed_command_except_trap
          being NULL

execute_cmd.c
        - fix execute_simple_command to deal with the_printed_command being
          NULL when assigning to the_printed_command_except_trap -- fixes
          seg fault in savestring()

parse.y
        - change the parser so that the closing `)' in a compound variable
          assignment delimits a token -- ksh93 does it this way

doc/{bash.1,bashref.texi}
        - change description of tilde expansion to note that expansion is
          attempted only after the first =~ in an assignment statement

builtins/declare.def
        - when assigning to an array variable with declare -a x=(...), make
          sure the last character in the rhs  of the variable assignment is
          `)', not just that it appears somewhere

                                   9/28
                                   ----
command.h
        - add a `W_NOEXPAND' flag to inhibit all expansion except quote removal
        - add a `W_COMPASSIGN' flag to denote a word is a compound assignment
          statement

parse.y
        - set W_COMPASSIGN on words that appear to be compound assignments

subst.c
        - pass W_NOXPAND and W_COMPASSIGN through end of expand_word_internal

subst.[ch]
        - new function, expand_assignment_string_to_string, calls
          expand_string_assignment and then string_list on the result

variables.c
        - assign_in_env now calls expand_assignment_string_to_string

                                   9/30
                                   ----

                                   ----
subst.c
        - do_assignment_internal now takes a WORD_DESC * as its first
          argument, and uses its `word' member as the assignment string
        - change expand_word_list_internal to call do_word_assignment instead
          of do_assignment, passing it `word' instead of, e.g., `word->word'
        - change extract_array_assignment_list to just return the passed
          string minus a trailing `)' if the last character is a right
          paren
        - change do_assignment_internal to call extract_array_assignment_list

subst.[ch]
        - change do_assignment and do_assignment_no_expand to take a `char *'
          instead of `const char *' first argument; change extern prototypes
        - new function, do_word_assignment, takes a WORD_DESC * and calls
          do_assignment_internal on it; add extern declaration with prototype

general.h
        - new typedef, sh_wassign_func_t, like sh_assign_func_t but takes a
          WORD_DESC * as its first argument

variables.[ch]
        - assign_in_env now takes a WORD_DESC * as its first argument

                                   ----
command.h
        - new word flag, W_ASSNBLTIN, denotes that the word is a builtin
          command (in a command position) that takes assignment statements
          as arguments, like `declare'
        - new word flags, W_ASSIGNARG, denotes that word is an assignment
          statement given as argument to assignment builtin

execute_cmd.c
        - set W_ASSNBLTIN flag in fix_assignment_words if necessary (if there
          are any arguments that are assignment statements)
        - set W_ASSIGNARG flag in fix_assignment_words if necessary

subst.c
        - new function, do_compound_assignment, encapsulates the necessary
          code to perform a compound array assignment (including creation of
          local variables); called from do_assignment_internal
        - to fix the double-expansion problem with compound array assignments
          that are arguments to builtins like `declare', changed
          shell_expand_word_list to treat those arguments like assignment
          statements (with proper creation of local variables inside shell
          functions) and pass the attribute-setting portion of the statement
          onto the builtin.  This is what ksh93 appears to do, from inspection
          of the `ksh93 -x' output

execute_cmd.c
        - fix execute_simple_command:  in case of pipeline or async command,
          when forking early, set `subshell_environment' so that it can contain
          both SUBSHELL_PIPE and SUBSHELL_ASYNC -- the two should not be
          mutually exclusive.  Fixes bug reported by pierre.humblet@ieee.org
        - remove references to last_pid, old_command_subst_pid; use NO_PID as
          a sentinel value to decide whether or not a child process has been
          created and needs to be waited for.  Submitted by
          pierre.humblet@ieee.org to fix recycling-pid problem on cygwin

doc/{bash.1,bashref.texi}
        - fixed documentation of `@(pattern)' extended globbing operator --
          it succeeds if the string matches one of the patterns, not exactly
          one.  This is what ksh93 does, too

lib/readline/complete.c
        - fixed rl_menu_complete so that a negative argument cycles backwards
          through the list

support/shobj-conf
        - additions for System V.5 from Boyd Gerber <gerberb@zenez.com>

subst.c
        - in command_substitute, if subshell_environment includes
          SUBSHELL_ASYNC, call make_child with the `async_p' argument set to
          non-zero.  This keeps command substitutions for async commands or
          pipelines from trying to give the terminal back to the shell's
          pgrp.  make sure to save and restore last_asynchronous_pid.  Fix
          suggested by <pierre.humblet@ieee.org>

aclocal.m4
        - add BASH_CHECK_WCONTINUED, checks for glibc bug where WCONTINUED is
          defined but rejected as invalid by waitpid(2)

configure.in
        - add call to BASH_CHECK_WCONTINUED, defines WCONTINUED_BROKEN

redir.c
        - experimental change to add_undo_redirect to save manipulations to
          file descriptors >= SHELL_FD_BASE (10) on the list of redirections
          to be undone even if `exec' causes the list to be discarded

doc/{bash.1,bashref.texi}
        - note that redirections using file descriptors > 9 should be used
          carefully, because they might conflict with file descriptors the
          shell uses internally

          alive_only, since we don't want recycled pids returned here and it
          better describes the result
        - new function find_process, calls find_pipeline and searches the
          returned pipeline for the PROCESS * describing the desired pid
        - in make_child, if fork() returns the same pid as the value of
          last_asynchronous_pid when RECYCLES_PIDS is defined, avoid pid
          aliasing by resetting last_asynchronous_pid to 1
        - use PRUNNING instead of child->running, since we, for the most
          part, don't want to consider recycled pids (e.g., in make_child())

          to the previous behavior if it does not.  This is what POSIX.2
          specifies, I believe (and the consensus of the austin-group list).
          This requires a few tests in read.tests to be changed: backslashes

          intended for functions that read a single additional character,

          using readline state and an auxiliary variable
        - support for callback code performing non-incremental searches using
          the same search context struct as the isearch code

          individually from the callback code more easily

          stack immediately so the loop in rl_callback_read_char terminates

          flag is not set in the current keyseq context -- if it is, we are
          traversing the chain back up and should use what we already saved
        - use -3 as a magic value from _rl_dispatch_subseq to indicate that
          we're allocating a new context and moving downward in the chain

[bash-3.1-beta1 released]

lib/readline/isearch.c
        - when switching directions, make sure we turn off the SF_REVERSE
          flag in the search context's flags word if we're going from reverse
          to forward i-search

lib/readline/bind.c
        - new function, rl_variable_value, returns a string representing a
          bindable readline variable's value
        - new auxiliary function, _rl_get_string_variable_value, encapsulates
          everything needed to get a bindable string variable's value
        - rewrote rl_variable_dumper to use _rl_get_string_variable_value

lib/readline/readline.h
        - new extern declaration for rl_variable_value

lib/readline/doc/rltech.texi
        - documented rl_variable_value

bashline.c
        - in command_word_completion_function, if readline sets
          rl_completion_found_quote, but doesn't set rl_completion_quote_character,
          we have an embedded quoted string or backslash-escaped character in
          the passed text.  We need to dequote that before calling
          filename_completion_function.  So far, this is in place only for
          absolute program names (those containing a `/')
        - in command_word_completion_function, use rl_variable_value to decide
          whether or not we should ignore case, and use strncasecmp instead of
          strncmp where appropriate

redir.h
        - new flag values for redirections: RX_INTERNAL and RX_USER (currently
          unused)

redir.c
        - add_undo_redirect and add_undo_close_redirect now set RX_INTERNAL
          flag when making new redirects
        - in do_redirection_internal, only set file descriptors > 2 to CLEXEC
          if they're marked as RX_INTERNAL

jobs.c

          from the list of background pids, forgetting it entirely.  POSIX
          conformance tests test for this.

lib/readline/{readline.h,vi_mode.c}
        - new state flag, RL_STATE_VICMDONCE, set after entering vi command
          mode the first time; reset on each call to readline()

          rl_point set to 0 no matter the state of the line buffer

lib/readline/vi_mode.c
        - when entering vi_command mode for the first time, free any existing
          undo list so the previous insertions won't be undone by the `U'
          command.  This is how POSIX.2 says `U' should work (and the test
          suite tests for it)

lib/readline/bind.c
        - change rl_parse_and_bind so only `set' commands involving boolean
          readline variables have trailing whitespace stripped from the value
          string

{jobs,nojobs,sig}.c,{jobs,sig}.h
        - moved SIGWINCH handling code to sig.c rather than duplicate it in
          jobs.c and nojobs.c
        - call set_sigwinch_handler from sig.c code rather than job control
          signal initialization

sig.[ch]
        - new variable, sigwinch_received, acts like interrupt_state for
          SIGWINCH, set by sigwinch_sighandler.  sigwinch_sighandler no longer
          calls get_new_window_size

parse.y

          new function xplit(mem, bucket) to split the block into two or more
          smaller ones and add those to the right bucket (appropriately marking
          it as busy)
        - audit bsplit(), bcoalesce(), and xsplit() for proper use of busy[],

          for invisible characters in the prompt string, make sure that
          _rl_last_c_pos is treated as an absolute cursor position in a

          rl_reset_screen_size as appropriate.  Only do this in posix mode
          and only when STRICT_POSIX is defined at compile time
        - new semaphore variable, winsize_assignment, set while doing an
          assignment to LINES or COLUMNS
        - new variable, winsize_assigned, says LINES or COLUMNS was assigned
          to or found in the environment

          operator, throw an error.  Try to be intelligent about what type of
          error message to print

subst.c

          used where an arithmetic expression needs to be expanded

subst.h
        - new extern declaration for expand_arith_string

arrayfunc.c
        - in array_expand_index, call expand_arith_string to expand the
          subscript in a fashion consistent with other arithmetic expressions

subst.c
        - fix parameter_brace_patsub so that we don't try to anchor the pattern
          at the beginning or end of the string if we're doing global

          can be redone properly
        - new function _rl_vi_backup, moves point back a character taking
          multibyte locales into account
        - change rl_vi_redo to handle redoing an `a' command specially --
          it should be redone like `i' but after moving forward a character

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
