CWRU/changelog

				 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())

parse.y
	- 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

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

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

pcomplete.c
	- add code to support CA_GROUP group name completion

bashline.c
	- new function, bash_groupname_completion_function(), supports
	  programmable completion of group names

bashline.h
	- extern declaration for bash_groupname_completion_function

lib/readline/bind.c
	- new inputrc variable, `match-hidden-files', controls completion
	  matching files beginning with a `.' (on Unix)

lib/readline/complete.c
	- new variable, _rl_match_hidden_files, mirrors `match-hidden-files'
	  inputrc variable

lib/readline/rlprivate.h
	- extern declaration for _rl_match_hidden_files

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

builtins/read.def
	- 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 cygnus 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
	  options like +o/-o sets and unsets `set -o' options

doc/{bash.1,bashref.texi}
	- document `set -o nolog'
	- document `login_shell' shopt option
	- document new `\A' prompt string escape sequence
	- document new `-t' option to `hash'
	- document new `[+-]O' invocation option

				   5/10
				   ----
configure.in
	- fix AC_CHECK_PROG(ar, ...)
	- add AC_CHECK_TYPE for ssize_t

config.h.in
	- new #undef for ssize_t

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
	- change second argument to type `char *', since ISO C says you have
	  to pass a `char *' to `write'

externs.h
	- fix extern declarations of zread, zread1, zreadc, and zwrite
	- prototype extern declaration of qsort_string_compare
	- add extern declaration for history_delimiting_chars() from parse.y

input.h
	- b_used and b_inputp members ofr struct BSTREAM are now size_t

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
	- ditto for yy_string_get and shell_getc (cast to unsigned char)

subst.c
	- instead of casting to unsigned char when assigning to ifscmap in
	  expand_word_internal, use a variable of type unsigned char and
	  let the compiler do the work

lib/sh/strtrans.c
	- instead of casting to unsigned char in ansic_quote, use a variable
	  of type unsigned char and let the compiler do the work

builtins/evalstring.c
	- remove extern declarations for zwrite and run_trap_cleanup; they're
	  in externs.h
	- prototype cat_file forward declaration

Makefile.in
	- remove -I$(includedir) from INCLUDES and SUBDIR_INCLUDES

aclocal.m4
	- change RL_LIB_READLINE_VERSION to set RL_PREFIX, RL_LIBDIR,
	  and RL_INCLUDEDIR to what it used to test the installed readline
	  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
	- updated description of --with-installed-readline configure option

	  brace_gobbler

error.c
	- prototype extern declaration of give_terminal_to, fix bad call

{execute_cmd,expr,findcmd,jobs,mailcheck,nojobs,pcomplete,print_cmd,redir,
shell}.c
	- prototype all static forward function declarations

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

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

make_cmd.h
	- changed extern declarations for make_bare_word and make_word

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

	  rl_parse_and_bind

lib/readline/{{bind,isearch}.c,rlprivate.h}
	- _rl_isearch_terminators is now a char *, not unsigned char *

{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()
	- take out cast to int in call to inttostr in set_ppid()

subst.c
	- don't cast last_asynchronous_pid when passing to itos()

{sig,subst}.c
	- prototype all static forward function declarations

				   5/14
				   ----

history,jobs,pushd,read,set,trap,umask,
	- prototype all static forward function declarations

builtins/read.def
	- reset_eol_delim now takes a `char *' arg, since that's what the
	  unwind_protect functions pass it, and it ignores its arguments
	  anyway

lib/readline/{histsearch,input,kill,rltty,search,vi_mode}.c
	- prototype all static forward function declarations

lib/tilde/tilde.c
	- prototype all static forward function declarations
	- tilde_find_prefix, tilde_find_suffix, isolate_tilde_prefix, and
	  glue_prefix_and_suffix now take `const char *' arguments where
	  appropriate

configure.in,config.h.in
	- check for vsnprintf, define HAVE_VSNPRINTF if found

lib/readline/display.c
	- use vsnprintf() in rl_message if it's available; if we don't, at
	  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
	  available, this fixes buffer overflow problems in rl_message

				   5/15
				   ----
lib/readline/histexpand.c
	- in get_history_word_specifier, allow any character to terminate
	  a `:first-' modifier, not just `:' and null.  This is what csh
	  appears to do.  This allows things like `!:0- xyzzy' to replace the
	  last argument with xyzzy

				   5/18
				   ----
configure.in, config.h.in
	- check for <stdint.h>, define HAVE_STDINT_H if found

	- add snprintf.c/snprintf.o

configure.in, config.h.in
	- add checks for snprintf, asprintf, vasprintf, with appropriate
	  cpp defines

lib/readline/{rldefs,xmalloc}.h, lib/readline/xmalloc.c
	- xmalloc and xrealloc now take `size_t' arguments, like their bash
	  counterparts

externs.h,lib/sh/itos.c
	- inttostr and itos now take `long' arguments
	- inttostr takes a `size_t' argument for the buffer size

{expr,lib/malloc/malloc,variables,general}.c
	- fixed calls to itos() by removing casts, etc.

subst.[ch]
	- get_dollar_var_value now takes a long, not an int
	- sub_append_number now takes a long, not an int

subst.c
	- in parameter_brace_expand_word, use a long and legal_number to
	  translate ${N}, to avoid overflow
	- in parameter_brace_expand_length, use a long and legal_number to
	  translate ${#N}, to avoid overflow
	- in do_array_element_assignment, array_expand_index,
	  array_value_internal, use arrayind_t instead of int
	- let verify_substring_values take long * arguments for the return
	  value of evalexp()
	- pass long * arguments to verify_substring_values in
	  parameter_brace_substring
	- parameter_brace_expand_length now returns `long'
	- parameter_brace_expand now uses a long variable for the return
	  value of parameter_brace_expand_length
	- param_expand now uses a long variable for the return value from
	  evalexp
	- array_length reference now returns an `arrayind_t', since it can
	  return the num_elements member of an array, which is of type
	  arrayind_t

subst.h
	- array_expand_index now returns an `arrayind_t'

array.[ch]
	- array_subrange now takes arrayind_t arguments, not `int'
	- dup_array_subrange now uses arrayind_t local variable to do
	  array indexing
	- use long to print array indices in print_element

variables.c
	- null_array_assign, assign_dirstack, bind_array_variable
	  now take arrayind_t arguments as array indices
	- assign_array_var_from_word_list, assign_array_var_from_string,
	  unbind_array_element now use arrayind_t local variables for
	  array indexing

variables.h
	- change extern declaration of bind_array_variable

builtins/common.[ch]
	- get_numeric_arg now returns a `long', since it usually returns
	  the value of legal_number()

builtins/history.def
	- convert string argument to int only if it's in range

builtins/pushd.def
	- set_dirstack_element and get_dirstack_element now take `long'
	  index arguments
	- get_dirstack_index now takes a `long' index argument, since it's
	  passed the converted value from legal_number

lib/sh/timeval.c
	- in print_timeval, don't assume that the number of minutes fits into
	  an int, since it's just seconds/60.

lib/sh/clock.c
	- ditto for print_clock_t

				   5/22
				   ----
shell.c
	- since the -O option settings may possibly be overridden by the
	  normal shell initialization or posix initialization, save the
	  invocation options on an alist (with add_shopt_to_alist) and
	  process them after basic initialization (with run_shopt_alist)

				   5/23
				   ----
trap.h
	- new define, BASH_NSIG, all system signals plus special bash traps

trap.c, builtins/trap.def
	- use BASH_NSIG for array bounds and loops where appropriate

trap.c
	- change decode_signal to disallow numeric signal numbers above
	  NSIG -- this means you can only reference special traps like
	  DEBUG by name
	- new SPECIAL_TRAP(s) macro to test whether s is one of the special
	  bash traps (currently DEBUG and EXIT)
	- change reset_or_restore_signal_handlers so command substitution
	  doesn't inherit the debug trap (like ksh93), and child processes
	  don't have to rely on initialize_traps being run to get rid of
	  any debug trap

support/mksignames.c
	- add extra "ERR" signal name, value NSIG+1, allocate space for it
	  and write it out in signal_names[]

trap.h
	- new define: ERROR_TRAP == NSIG+1, change BASH_NSIG to NSIG+2
	- extern declarations for set_error_trap, run_error_trap
	- new define: TRAP_STRING(s), expands to trap_list[s] if signal S
	  is trapped and not ignored, NULL otherwise

trap.c
	- add ERROR_TRAP to SPECIAL_TRAPS define
	- initialize ERROR_TRAP stuff in initialize_traps
	- new function: set_error_trap(command), sets the ERR trap string
	- new function: run_error_trap(command), runs the ERR trap string
	- set trap string for ERROR_TRAP to NULL in free_trap_strings
	- change reset_or_restore_signal_handlers so child processes don't
	  inherit the ERR trap
	- add case to call run_error_trap in maybe_call_trap_handler

execute_cmd.c
	- in execute_command_internal, keep track of ERR trap and call it if
	  necessary
	- use TRAP_STRING to get the value of debug and error traps
	- 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}
	- added ERR trap tests

subst.c
	- on machines without /dev/fd, change the named pipe fifo list to a
	  list of structs containing pathname and proc information
	- change unlink_fifo_list to kill the proc in the fifo list with
	  signal 0 and not remove the fifo if the proc is still alive.  This
	  should fix the problem on those backward systems without /dev/fd
	  where fifos were removed when a job using process substitution was
	  suspended

				   5/24
				   ----
examples/loadables/getconf.h
	- new file, with basic defines needed to make getconf work minimally
	  on POSIX systems without the necessary definitions

examples/loadables/getconf.c
	- replacement functions for confstr, sysconf, pathconf for systems
	  that lack them, providing a minimal posix interface
	- heavily augmented getconf, now supports all POSIX.1-200x,
	  POSIX.2-200x, Solaris 7, AIX 4.2 getconf variables

				   5/29
				   ----
builtins/setattr.def
	- make `readonly', `export', and `declare' print `invisible' variables
	  as just a command and variable name, without a value, when listing
	  all variables (as POSIX.2-200x d6 requires)

				   5/30
				   ----

configure.in
	- upgraded to autoconf-2.50 on main development machine, so require
	  autoconf-2.50 in preparation for using some if its new features
	- call AC_C_PROTOTYPES
	- remove call to AC_EXEEXT, which now does the wrong thing
	- changed AC_INIT to new flavor

	- AC_CONFIG_HEADER -> AC_CONFIG_HEADERS
	- AC_RETSIGTYPE -> AC_TYPE_SIGNAL

configure.in, aclocal.m4, config.h.in
	- removed call to BASH_LARGE_FILE_SUPPORT, use AC_SYS_LARGEFILE

doc/bashref.texi
	- document new `--enable-largefile' configure option

lib/readline/readline.c

	  local_prompt and local_prompt_prefix get set correctly

				    6/6
				    ---
lib/readline/complete.c
	- don't append `/' or ` ' to a match when completing a symlink that
	  resolves to a directory, unless the match doesn't add anything
	  to the word.  This means that a tab will complete the word up to
	  the full name, but not add anything, and a subsequent tab will add
	  a slash.  Change to append_to_match; callers changed

hashlib.c
	- new function, hash_table_nentries (table), returns the number of
	  items in TABLE

hashlib.h
	- extern declaration for hash_table_nentries

configure.in
	- configure without bash malloc on openbsd; they claim it needs
	  eight-bit alignment (which the bash malloc provides, but...)

				    7/2
				    ---
stringlib.c
	- only call RESIZE_MALLOCED_BUFFER from strsub() if the replacement
	  string length is > 0, avoid possible hangs if replacement is null

subst.c
	- don't include input.h; no longer needed

configure.in
	- remove calls to AC_SYS_RESTARTABLE_SYSCALLS and
	  BASH_SYS_RESTARTABLE_SYSCALLS; the results are no longer used

	- remove define for HAVE_RESTARTABLE_SYSCALLS

aclocal.m4
	- removed definition of BASH_SYS_RESTARTABLE_SYSCALLS; no longer used

execute_cmd.c

	  command, so it can be used to return from an enclosing function.
	  This is as ksh (88 and 93) does it

lib/readline/vi_mode.c
	- fix trivial typo in declaration of vi_motion; `t' appears twice;
	  the second instance should be `T'

				    7/3
				    ---
configure.in
	- don't add -static to LDFLAGS on Solaris 2.x.  This means that the
	  auxiliary programs will be built as dynamic executables, but that
	  should do no harm

				    7/5
				    ---
lib/glob/fnmatch.c
	- fix the code that processes **(pattern) to short-circuit if the
	  pattern is ill-formed or lacks a trailing `)'  -- this fixes the
	  segfault on **(/*)

Makefile.in, builtins/Makefile.in
	- split CCFLAGS into CCFLAGS_FOR_BUILD and CFLAGS, to aid in
	  cross-compilation
	- build programs that use $(CC_FOR_BUILD) using $(CCFLAGS_FOR_BUILD)

configure.in, config.h.in
	- check for getaddrinfo(3), define HAVE_GETADDRINFO if found

lib/sh/netopen.c
	- implemented a version of _netopen (_netopen6) that uses
	  getaddrinfo(3) if available, use if HAVE_GETADDRINFO is defined.
	  old _netopen is _netopen4; _netopen now calls either _netopen6
	  or _netopen4 as appropriate

				    7/9
				    ---
builtins/exit.def
	- don't source ~/.bash_logout if subshell_environment is non-zero

execute_command.c
	- in execute_until_or_while, handle the case where `breaking' is
	  set in the loop test (e.g., by the job control code when a job
	  is stopped with SIGTSTP), but the return value from the test is
	  something that would cause the loop to break.  Need to decrement
	  `breaking' in this case

				   7/10
				   ----
execute_cmd.c
	- in execute_in_subshell, make sure a command of type cm_subshell
	  inherits its `enclosing' command's CMD_IGNORE_RETURN flag

variables.c

	  exported functions in the export environment

pathexp.h,builtins/help.def
	- include <glob/strmatch.h>
	- fnmatch -> strmatch

execute_cmd.c
	- broke the code that parses the interpreter name from a #! line
	  out from execute_shell_script to a new function, getinterp()
	- call getinterp from execute_shell_script
	- use return value from getinterp in error message about bad
	  #! interpreter in shell_execve

				   7/12
				   ----
lib/readline/isearch.c
	- the last isearch string is now remembered in a new static variable,
	  last_isearch_string
	- if ^R^R is typed, readline now searches for the remembered isearch
	  string, if one exists

pcomplete.h
	- extern declaration for completions_to_stringlist()

	- make compgen return success only if sl->list_len is non-zero,
	  indicating that there are items on the list

				   7/31
				   ----
execute_cmd.c
	- in execute_connection, force stdin to /dev/null for asynchronous
	  commands if job control is not active, not just if the shell is
	  running a shell script (since you can run `set -m' in a script)

lib/readline/rltty.c
	- make sure _rl_tty_restore_signals resets `tty_sigs_disabled' on
	  successful restoration of the terminal modes
	- make sure _rl_tty_disable_signals turns off IXON so that ^S and
	  ^Q can be read by rl_quoted_insert

aclocal.m4
	- new check for FNM_EXTMATCH being defined in <fnmatch.h>, as Ullrich
	  Drepper intends to do for new versions of GNU libc

lib/sh/{strcasecmp,strtod,strtol}.c
	- don't pass possibly-negative characters to tolower() or toupper()

	- don't use local definitions of isblank, et al.; rely on macros
	  from <chartypes.h>

lib/readline/{display,readline}.c, mksyntax.c

{execute_cmd,subst}.c
	- change a couple of instances of ISDIGIT to DIGIT, where we really,
	  really only want ascii digits

ansi_stdlib.h
	- don't need a declaration for atol()

				   10/18
				   -----

aclocal.m4
	- new macro, BASH_FUNC_PRINTF_A_FORMAT, checks for printf support
	  for %a, %A conversion specifiers, defines HAVE_PRINTF_A_FORMAT
	  if successful

configure.in
	- call AC_CHECK_FUNCS for isascii
	- call BASH_FUNC_PRINTF_A_FORMAT

config.h.in
	- add a define for HAVE_ISASCII
	- add a define for HAVE_PRINTF_A_FORMAT

lib/sh/snprintf.c
	- for long double output, fall back to sprintf using ldfallback()
	  function for floating point formats
	- support %a, %A using dfallback() or ldfallback() if
	  HAVE_PRINTF_A_FORMAT is defined
	- fix bug in vasprintf that returned wrong value in its first
	  argument if the buffer holding the result string got reallocated
	- fixed PUT_CHAR macro to increment the counter even if we've
	  exceeded the buffer size, for the return value from
	  vsnprintf/snprintf
	- fix vsnprintf_internal to not use counter < length as a loop

	  the return value from vsnprintf/snprintf)

builtins/printf.def
	- support %a, %A if HAVE_PRINTF_A_FORMAT is defined

include/typemax.h
	- new file, with the TYPE_MAXIMUM stuff that's duplicated in several
	  files in lib/sh

lib/sh/{fmtulong,strtol,snprintf}.c
	- include <typemax.h> instead of having the definitions in each file

lib/sh/Makefile.in

	  in chartypes.h

config.h.in
	- defines for HAVE_IS{ASCII,BLANK,GRAPH,PRINT,SPACE,XDIGIT}

include/chartypes.h, lib/glob/strmatch.c, lib/readline/chardefs.h
	- 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.c
	- new function, bind_var_to_int (char *var, long val)

variables.h
	- extern declaration for bind_var_to_int

{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)

				   10/24
				   -----
variables.c
	- if posixly_correct is set, the default value of $MAILCHECK is 600
	- use legal_number instead of atoi in adjust_shell_level

	- new function, init_funcname_var; sets FUNCNAME as a dynamic variable
	  if it's not set in the initial environment
	- new function, init_groups_var; sets GROUPS as a dynamic array
	  variable if it's not set in the initial environment
	- new function, init_dirstack_var; sets DIRSTACK as a dynamic array
	  variable if it's not set in the initial environment
	- new function, init_seconds_var; sets SECONDS as a dynamic
	  variable using any valid integer value in the initial environment
	  as the initial value, as if an assignment had been performed
	- 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 initialize_shell_variables to not auto-export PATH or TERM
	- 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

				   10/25

				   -----
locale.c
	- fixed an `=' vs. `==' typo in set_locale_var when parsing
	  LC_NUMERIC

doc/builtins.1
	- some updates

builtins/psize.sh
	- some mktemp(1) changes

lib/readline/readline.c
	- change rl_backward to check for rl_point < 0 and reset to 0 if so

	- don't compile in _rl_strpbrk if HAVE_STRPBRK is defined

lib/readline/rlprivate.h
	- remove extern declaration of _rl_strpbrk

builtins/common.c
lib/sh/pathcanon.c
	- a few changes as the result of `gcc -Wall' patches from solar
	  designer

builtins/read.def, parse.y
	- change some calls to free() to xfree()

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
	  difference on 32-bit machines)

				   10/30
				   -----
print_cmd.c
	- fixed cprintf to avoid gcc warning about assigning const pointer
	  to non-const (discarding type qualifier)

{make_cmd,pcomplete,test}.c,parse.y

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
	- use $TMPDIR instead of hardcoding /tmp; default to /tmp
	- use a better filename for the symlink test instead of `z'

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
	- slight change to RL_LIB_READLINE_VERSION to deal with minor version
	  numbers with a letter appended (like 4.2a)

				   10/31
				   -----
doc/{bash.1,bashref.texi}
	- slight change to note that only interactive shells resend a SIGHUP
	  to all jobs before exiting

externs.h
	- declare strto[ui]max only if NEED_STRTOIMAX_DECL is defined.  This
	  keeps picky compilers from choking because intmax_t is not defined
	  (MacOS X 10.1)

builtins/printf.def
	- #define NEED_STRTOIMAX_DECL before including shell.h

				   11/1
				   ----
general.c
	- check in bash_tilde_expand() for an unquoted tilde-prefix; don't
	  bother passing the string to tilde_expand unless the prefix is

shell.c
	- fix a problem with $LINENO when executing commands supplied with
	  the -c invocation option when ONESHOT is defined

[bash-2.05a-rc1 frozen]

builtins/printf.def
	- fix the %n conversion to require that the variable name supplied
	  be a valid shell identifier

variables.c
	- improve random number generator slightly by using the upper 16
	  bits of the running random number instead of the lower 16, which
	  are incrementally more random

				   11/2

configure.in
	- if RL_INCLUDEDIR ends up being /usr/include, don't put
	  -I$(RL_INCLUDEDIR) into CFLAGS

				   11/5
				   ----
doc/{bash.1,bashref.texi}
	- correct description of POSIXLY_CORRECT to note that the shell enters
	  posix mode *before* the startup files are read if POSIXLY_CORRECT
	  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
	  potentially be called recursively

bashline.c
	- quick fix to bashline.c:attempt_shell_completion programmable
	  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
	  is probably in find_cmd_start -- fix later)

pcomplete.c
	- fix gen_matches_from_itemlist to return if the stringlist is null
	  after any cleaning or initialization, before trying to use it
	- fix GEN_COMPS to only bother to try to append the STRINGLIST
	  returned by gen_matches_from_itemlist to `glist' if it's non-NULL

lib/sh/stringlist.c
	- make copy_stringlist return NULL if the STRINGLIST * passed as an
	  argument is NULL
	- make append_stringlist call copy_stringlist only if M2 is non-NULL;
	  otherwise just return NULL if m1 is NULL
	- make word_list_to_stringlist return 0 immediately if the passed
	  LIST argument is NULL
	- make realloc_stringlist call alloc_stringlist if the passed
	  STRINGLIST argument (`sl') is 0, just like realloc calls malloc

subst.c
	- in skip_to_delim(), if we have an unclosed ${, and it's at the end
	  of the string (string[i] == '{', string[i+1] == '{' and
	  string[i+2] == 0, return si (i +2) immediately without bothering
	  to call extract_dollar_brace_string or extract_delimited_string
	- in skip_to_delim(), if string[i] is 0 after a call to
	  extract_dollar_brace_string or extract_delimited_string (meaning we
	  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
	  single-char delimiters like `>'

configure.in
	- use AC_CHECK_MEMBERS([struct stat.st_blocks]) instead of a call to
	  AC_STRUCT_ST_BLOCKS to avoid configure changing LIBOBJS if the test
	  fails

general.c
	- introduce two new variables: bash_tilde_{prefixes,suffixes}, set
	  to the additional prefixes and suffixes bash wants to pass to the
	  tilde expansion code (reserved for post-bash-2.05a fix)

aclocal.m4
	- add missing `test' in BASH_CHECK_SYS_SIGLIST

				   11/7
				   ----
lib/readline/vi_mode.c
	- fix rl_vi_goto_mark to explicitly check that the desired mark is
	  between 'a' and 'z', since some locales have lowercase letters
	  outside that range, which could cause a negative subscript

include/chartypes.h
	- remove superfluous `#undef ISASCII'

lib/sh/strto[iu]max.c
	- changes from Paul Eggert to work around buggy compilers and catch
	  configuration errors at compile time

aclocal.m4
	- new macro, BASH_C_LONG_DOUBLE, identical to AC_C_LONG_DOUBLE but
	  with a fix for Irix 5.3 (not called, since I'm not sure it's the
	  right thing to do -- the C standard allows double and long double
	  to be the same size)

lib/sh/snprintf.c
	- only try to write the trailing NUL in vsnprintf_internal if
	  data->length is >= 0, since if it's not, we probably don't have
	  a buffer

Makefile.in
	- changed RELSTATUS to `release'

				   11/8
				   ----
lib/sh/strtol.c
	- make sure chars passed to toupper are cast to unsigned

unwind_prot.c
	- change clear_unwind_protect_list to not require a cast from `int'
	  to `char *'

lib/readline/chardefs.h
	- make _rl_digit_p succeed only for ascii digits, since that's what
	  most callers assume
