----
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
----

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

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

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

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)

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
---

- 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

testing against each possible modifier character, save any mod
character found

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

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

builtins/bind.def
- use unwind_protect_var on rl_outstream
general.c

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
---

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

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

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

- 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)

- 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

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

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

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

----
lib/readline/bind.c
- make `useq' a char array to pass to rl_macro_bind in
rl_parse_and_bind
lib/readline/{{bind,isearch}.c,rlprivate.h}

- dollar_dollar_pid is now a `pid_t' instead of `int'
variables.c
- sbrand() now takes an `unsigned long' to set the seed value

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

- parameter_brace_expand now uses a long variable for the return
value of parameter_brace_expand_length

return the num_elements member of an array, which is of type
arrayind_t

- array_expand_index now returns an `arrayind_t'
array.[ch]
- array_subrange now takes arrayind_t arguments, not `int'

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/{shift,break}.def
- use long variables for the return value of get_numeric_arg
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

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

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

standard support, with new macros _FILE_OFFSET_BITS and
_LARGE_FILES
- removed definition of BASH_LARGE_FILE_SUPPORT
doc/bashref.texi

lib/readline/readline.c
- change rl_set_prompt to call rl_expand_prompt unconditionally, so
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...)

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

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'

configure.in
- don't add -static to LDFLAGS on Solaris 2.x. This means that the

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

- 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

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

- new functions: getllong, getullong, getintmax, getuintmax; return
long long, unsigned long long, intmax_t, uintmax_t respectively
- builtin printf now handles `ll' and `j' length modifiers directly
lib/sh/Makefile.in
- use LIBOBJS to decide whether or not the strto* functions are
needed
10/17
-----
configure.in
- call AC_REPLACE_FUNCS(rename)
- move getcwd, strpbrk, strcasecmp, strerror, strtod
from AC_CHECK_FUNCS to AC_REPLACE_FUNCS
- only call BASH_FUNC_GETCWD if $ac_func_getcwd == "yes"
- call BASH_CHECK_SYS_SIGLIST
- if we don't have vprintf but have _doprnt, call AC_LIBOBJ(vprint)
lib/sh/Makefile.in
- remove rename, getcwd, inet_aton, strpbrk, strcasecmp, strerror,
strtod, vprint from OBJECTS; picked up from LIBOBJS
aclocal.m4
- change BASH_FUNC_GETCWD to call AC_LIBOBJ(getcwd) if the libc
getcwd(3) calls popen(3)
- change BASH_FUNC_INET_ATON to call AC_LIBOBJ(inet_aton) if it's
not found in libc or as a #define even with the special includes
- BASH_KERNEL_RLIMIT_CHECK -> BASH_CHECK_KERNEL_RLIMIT
- BASH_DEFAULT_MAILDIR -> BASH_SYS_DEFAULT_MAILDIR
- BASH_JOB_CONTROL_MISSING -> BASH_SYS_JOB_CONTROL_MISSING
- BASH_REINSTALL_SIGHANDLERS -> BASH_SYS_REINSTALL_SIGHANDLERS
- BASH_SIGNAL_CHECK -> BASH_SYS_SIGNAL_VINTAGE
- BASH_DUP2_CLOEXEC_CHECK -> BASH_FUNC_DUP2_CLOEXEC_CHECK
- BASH_PGRP_SYNC -> BASH_SYS_PGRP_SYNC
- BASH_RLIMIT_TYPE -> BASH_TYPE_RLIMIT
- BASH_FUNC_PRINTF -> BASH_DECL_PRINTF
- BASH_FUNC_SBRK_DECLARED -> BASH_DECL_SBRK
- BASH_MISC_SPEED_T -> BASH_CHECK_SPEED_T
- BASH_CHECK_SOCKLIB -> BASH_CHECK_LIB_SOCKET
- new macro, BASH_CHECK_SYS_SIGLIST, encapsulates all the checks for
sys_siglist, _sys_siglist, and strsignal(), sets SIGLIST_O to
siglist.o if appropriate
Makefile.in
- use SIGLIST_O variable to decide whether or not we need siglist.o
{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
condition, but always process the entire format string (for
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
- updated dependencies for typemax.h
10/22
-----
configure.in
- call AC_CHECK_FUNCS on ctype.h functions/macros that bash redefines
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 $'...'
externs.h
- new declaration for ansic_shouldquote()
variables.c
- change print_var_value to ansi C quote the string if we're not in
posix mode and the variable's value contains non-printing chars,
to use the regular shell single quoting if the value contains
shell meta-characters, and to just output the string otherwise
lib/sh/shquote.c
- add `break' to `case '~':' to avoid fallthrough and extra test
doc/bashref.texi
- note that in POSIX mode, `set' displays variable values that
include nonprinting characters without quoting, unless they
contain shell metacharacters
builtins/printf.def, lib/sh/snprintf.c
- handle `F' conversion specifier as equivalent to 'f'
parse.y, {nojobs,variables}.c
- a couple of cleanups for when building a minimal configuration
nojobs.c
- new function: stop_making_children(), just sets
already_making_children to 0 (like stop_pipeline)
subst.c
- call stop_making_children from subst.c:command_substitute if
JOB_CONTROL is not defined. This fixes the bug where the wrong
process is waited for (and its status returned) when using
command substitution in a null command in a shell function
builtins/printf.def
- new variable `tw' used to keep track of the total number of
characters written by a single call to `printf' -- to be
used for the `%n' conversion, which will be added later. It
gets reset each time we reuse the format string, which is what
ksh93 seems to do
10/23
-----
variables.c
- new function, bind_var_to_int (char *var, long val)
variables.h
- extern declaration for bind_var_to_int
lib/sh/netopen.c
- use gai_strerror() for error messages when getaddrinfo() fails
- use PF_INET if DEBUG is defined, since IPv6 doesn't work for me
Makefile.in
- pass DEBUG=${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)
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
- treat non-numeric assignments to SECONDS as 0 in assign_seconds
- 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
-----
Makefile.in
- changed RELSTATUS to `rc1' (release candidate 1)
10/29
-----
locale.c
- fixed an `=' vs. `==' typo in set_locale_var when parsing
LC_NUMERIC
doc/{bash.1,bashref.texi}
- document what bash does with $POSIXLY_CORRECT
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
lib/readline/util.c
- don't compile in _rl_strpbrk if HAVE_STRPBRK is defined
lib/readline/rlprivate.h
- remove extern declaration of _rl_strpbrk
lib/readline/rldefs.h
- #define _rl_strpbrk as strpbrk if HAVE_STRPBRK is define, otherwise
add extern declaration of _rl_strpbrk from rlprivate.h
{mailcheck,shell,variables}.c
- make sure to include posixtime.h to get any prototype for time(3)
in scope
{array,eval,execute_cmd,mksyntax,subst}.c, parse.y
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
- 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
- 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
unquoted
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
11/13
-----
doc/bashref.texi
- added `ERR' trap and [-+]O invocation option to section listing
differences from the Bourne shell
11/15
-----
[bash-2.05a released]
11/19
-----
include/stdc.h
- new define, INLINE, defined as `inline' for gcc and empty otherwise
subst.c
- make skip_double_quoted, sub_append_string have INLINE attribute
trap.c
- use BASH_NSIG as upper limit for signal names in signal_name()
lib/readline/bind.c
- use RL_COMMENT_BEGIN_DEFAULT in output for rl-comment-begin value
error.c
- fix sys_error to save value of errno around calls to fprintf
doc/Makefile.in
- added rules to create PDF files from postscript and dvi input
MANIFEST.doc
- added {article,bash,bashref,rose94}.pdf
doc/bash.1
- rearranged some `.PD 0' and `.TP' directives so man2html will
handle them better (shouldn't affect groff output)
support/man2html.c
- small fix to handle quoted string arguments to directives like
`.BR' without mangling the output
11/20
-----
{arrayfunc,variables}.c
- changed calling sequence for dynamic array variable `assign'
functions to (SHELL_VAR *self, char *value, arrayind_t ind)
- changed calling sequence for dynamic variable assign functions
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
`sh_var_assign_func_t', which is prototyped
- the dynamic_value member of a `struct variable' is now of type
`sh_var_value_func_t', which is prototyped
variables.c
- changed to use `sh_var_assign_func_t' and `sh_var_value_func_t'
builtins/cd.def
- when in posix mode, if the new directory name formed by PWD and
the argument passed by the user cannot be canonicalized, and the
-P option has not been supplied, return failure immediately
- 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
11/21
-----
lib/readline/readline.c
- bind common arrow key sequences in vi insertion keymap
lib/readline/terminal.c
- bind termcap definition's arrow keys in vi insertion keymap
lib/readline/bind.c
- check for rl_vi_movement_mode in _rl_bind_if_unbound, so
binding the arrow keys can work
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
saving and restoring _rl_keymap; changed bind_arrow_keys
accordingly
builtins/fc.def
- fix from Paul Eggert to substitute the nearest history number in
range if an out-of-range value is supplied. POSIX requires this
lib/sh/pathcanon.c
- fix from Corrina Vinschen for the special `cygdrive' prefix on
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)
11/24
-----
command.h
- new flag, W_TILDEEXP, says to do tilde expansion on an
assignment word
execute_cmd.c
- fix_assignment_words now sets W_TILDEEXP for assignment word
arguments to `assignment builtins'
general.c
- bash_tilde_expand now takes a second argument indicating whether
or not it's being invoked in an `assignment context'
general.h
- change extern declaration for bash_tilde_expand
{bashline,execute_cmd,findcmd,general,variables}.c
builtins/evalfile.c
lib/sh/makepath.c
- fix callers of bash_tilde_expand appropriately
subst.c
- fix callers of bash_tilde_expansion appropriately
- add (currently commented-out) code that would tilde expand assignment
statement arguments to assignment builtins (W_TILDEEXP flag set)
even when the shell is in posix mode
bashline.c
- fix attempt_shell_completion to turn off
rl_filename_completion_desired when doing command name completion,
so no slash gets appended to the name if there happens to be a
directory with the same name in the current directory
11/26
-----
lib/readline/rltech.texinfo
- a couple of additions to the rl_stuff_char description
parse.y
- turn off echo_input_at_read in parse_string_to_word_list, so `set -v'
doesn't give extra lines of output when doing compound array
assignment
subst.c
- fix split_at_delims to handle skipping over a `\n' if it's a
delimiter (use spctabnl(c) instead of whitespace(c))
11/27
-----
support/config.{guess,sub}
- updated (with bash changes) to latest version from gnu.org
sig.h
- add prototype for set_signal_handler declaration
builtins/setattr.def
- add prototype to extern declaration of declare_builtin
builtins/times.def
- add no_options call, since times takes no options
lib/sh/spell.c
- add prototypes to forward declarations for midist and spdist
lib/sh/strtrans.c
- add explicit int return type to ansic_shouldquote declaration
lib/readline/rldefs.h, lib/readline/{macro,readline,util,undo}.c
- move define for SWAP to rldefs.h, removed from various C files
lib/readline/vi_mode.c
- removed define for exchange(), changed to use SWAP instead
lib/readline/bind.c
- added some static forward function declarations
- find_boolean_var, find_string_var now take a `const char *' argument
lib/readline/signals.c
- added static forward declaration for rl_maybe_set_sighandler
lib/readline/readline.c
- add some common key bindings for the HOME and END keys in
bind_arrow_keys_internal
lib/readline/terminal.c
- fetch the `@7' termcap string; it's sent by the END key
- attempt to bind the terminal's END key to rl_end_of_line in
bind_termcap_arrow_keys; I don't know why I was using `kH'
instead of `@7'
doc/builtins.1
- remove `case', `for', `if', `until', `while' from NAME section;
those are not shell builtins
11/28
-----
stringlib.c
- new function, find_token_in_alist, takes a token value and an
ALIST argument, and returns the string correspoinding to the
token if found in the alist
externs.h
- new extern declaration for find_token_in_alist()
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
- fixed typo in BASH_CHECK_LIB_TERMCAP
configure.in
- add check for isinf(3); define HAVE_ISINF_IN_LIBC if found
config.h.in
- add define for HAVE_ISINF_IN_LIBC
lib/sh/snprintf.c
- check for Inf and NaN, using isinf and isnan if they're found in
libc
- use the current locale for thousands separator and decimal point
- recognize "'" flag; not implemented yet
- 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
- added item to posix mode section describing failure behavior of
cd when invoked in logical mode and the pathname formed by
combining $PWD and the directory argument does not refer to an
existing directory
11/29
-----
execute_cmd.c
- fix execute_function to call dispose_function_env after
merge_function_env if the shell is in posix mode (fixes debian
bash bug #117673)
lib/readline/readline.c
- rl_forward -> rl_forward_char; rl_forward function for compatibility
- rl_backward -> rl_backward_char; rl_forward function for
compatibility
- new functions, rl_forward_byte, rl_backward_byte, for future use
lib/readline/readline.h
- extern declarations for rl_forward_char, rl_backward_char,
rl_forward_byte, rl_backward_byte
lib/readline/{emacs_keymap,funmap,vi_keymap,vi_mode
- rl_forward -> rl_forward_char
- rl_backward -> rl_backward_char
lib/readline/funmap.c
- new bindable names, `backward-byte' and `forward-byte'
aclocal.m4
- new function, BASH_CHECK_MULTIBYTE, encapsulates checks for
multibyte code
config.h.in
- add necessary defines for multibyte include files and functions
configure.in
- add call to BASH_CHECK_MULTIBYTE
config-bot.h
- add code to define HANDLE_MULTIBYTE if prerequisites are met
lib/sh/xstrchr.c
- new file, xstrchr() is strchr(3) that handles multibyte characters
bashhist.c
- first_line_saved -> current_command_first_line_saved; variable is
now global
bashhist.h
- extern declaration for current_command_first_line_saved
11/30
-----
bashhist.c
- break the code that actually calls add_history out of
bash_add_history into a new function, really_add_history;
bash_add_history now calls really_add_history
- check_add_history takes a second `force' argument telling it
whether to call bash_add_history (force == 0) or really_add_history
(force != 0)
builtins/history.def
- in push_history, call delete_last_history if the current command
has more than one line, the first line was saved, and
command-oriented history is active. This takes care of deleting
the right history element if `history -s' is used within a
compound or multiline command
- in push_history, call check_add_history with second argument of 1
to skip check of current_command_line_count and add the arguments
to history -s as a single separate history entry
12/3
----
lib/readline/complete.c
- append a slash to completed names which are symlinks to directories
if the new variable _rl_complete_mark_symlink_dirs is non-zero
lib/readline/rlprivate.h
- extern declaration for _rl_complete_mark_symlink_dirs
lib/readline/bind.c
- new bindable variable, `mark-symlinked-directories', mirrors the
value of _rl_complete_mark_symlink_dirs
doc/bash.1, lib/readline/doc/{readline.3,rluser.texinfo}
- documented new `mark-symlinked-directories' variable
12/4
----
variables.[ch]
- set_pipestatus_array now takes a second argument with the number
of processes in the array
- changed set_pipestatus_array to just modify the value in place if
the existing array has one element and the new array has one
element, and to modify existing values in place if new array has
more elements than existing array
variables.c, jobs.c
- changed set_pipestatus_array callers
jobs.c
- moved call to setjstatus() from set_job_status_and_cleanup to
wait_for, since set_job_status_and_cleanup is part of the SIGCHLD
signal handler call path, and race conditions accessing the
PIPESTATUS array will result for things like
while true; do date; done | cat > /dev/null
12/5
----
xmalloc.h
- don't redefine xmalloc, xrealloc, and xfree if DISABLE_MALLOC_WRAPPERS
is #defined
config.h.in
- #undef for DISABLE_MALLOC_WRAPPERS
configure.in
- define DISABLE_MALLOC_WRAPPERS if the --with-purify option is
supplied
lib/malloc/trace.c
- new function, malloc_trace_bin(N), traces allocations and frees
to bucket N (uses the same type of bitmap as `busy')
lib/malloc/table.c
- fix wraparound search problem in find_entry when searching for a
free entry when the table is full
12/6
----
lib/malloc/table.c
- keep an `overflow bucket' around to use when the table is full,
so find_entry always returns a valid pointer when FIND_ALLOC
is set
- new static variable to keep a count of the number of MT_ALLOC
entries in the mem_table
lib/sh/{oslib,clktck}.c
- if HAVE_LIMITS_H is defined, include <limits.h>
lib/sh/oslib.c
- new function, getmaxgroups() returns max number of simultaneous
groups
- new function, getmaxchild(), returns max number of simultaneous
user processes
general.c
- removed forest of #defines for getmaxgroups()
externs.h
- new extern declaration for getmaxgroups()
- new extern declaration for getmaxchild()
- new extern declaration for isnetconn()
lib/sh/netconn.c,shell.c
- new file, isnetconn() from shell.c moved here
Makefile.in, lib/sh/Makefile.in
- necessary changes for netconn.c
builtins/ulimit.def
- changed getmaxuprc() to just call getmaxchild() and massage the
return value appropriately
{jobs,nojobs}.c
- use the value returned by getmaxchild() in
mark_dead_jobs_as_notified instead of static CHILD_MAX
jobs.c
- new function, compact_jobs_list, removes some number of jobs from
the jobs table and reallocates the table, copying the jobs that
are left from the old table to the new. Compaction happens from
the beginning of the list and removes dead jobs, and we make sure
to keep the last CHILD_MAX jobs as POSIX.2 requires
- call compact_jobs_list from stop_pipeline if we're in a subshell,
there are no free jobs in the jobs table, and the jobs table is
at or above some maximum limit
execute_cmd.c
- change eval_arith_for_expr to set this_command_name to `((' before
calling evalexp, since it might be changed by evaluating the
loop body between evalexp calls
trap.c
- change reset_signal to turn off the SIG_TRAPPED flag for the
given signal, so shell builtins and functions running in command
substitutions don't run the signal handlers (traps are not supposed
to be inherited by command substitutions)
parse.y
- changed parse_string_to_word_list to turn off alias expansion
while parsing the array assignment
12/9
----
alias.c
- fix add_alias so that redefining an alias's value also resets the
EXPANDNEXT flag
12/10
-----
parse.y
- new function, token_is_assignment, called to check whether the text
before `=' makes up a valid assignment token before trying to parse
a compound assignment statement
- new function, parse_compound_assignment, to parse a compound
assignment statement instead of using parse_matched_pair; handles
comments and error reporting in the parser instead of waiting until
expansion time
- changed parse_compound_assignment and parse_string_to_word_list to
allow reserved words in compound array assignments
lib/readline/doc/rltech.texinfo
- changed the documentation for rl_callback_read_char and
rl_callback_handler_remove to say what happens to the terminal
settings and what needs to be done to reset them
12/11

doc/{bash.1,bashref.texi}
- add note to section describing lists to clarify that a sequence of
one or more newlines may be used to delimit a command, equivalent
to a semicolon
- document new [:word:] pattern matching character class
doc/bash.1, lib/readline/doc/rluser.texinfo
- document `edit-and-execute-command' and its default emacs-mode
binding
include/chartypes.h
- add defines for TOCTRL and UNCTRL if they're not already defined
lib/readline/chardefs.h
- #undef UNCTRL if it's defined to avoid cpp redefinition warnings
lib/sh/strtrans.c
- add \cX (Control-X) escape for $'...' to ansicstr()
- change ansic_quote() to allocate at least four chars for each char
in the string argument, to account for \0xx octal values
- change ansic_quote() to no longer call sprintf for non-printable
characters; just translate the string to octal directly
print_cmd.c
- change xtrace_print_word_list to call ansic_quote() if
ansic_shouldquote() indicates that there are nonprinting characters
in a word
builtins/type.def
- changed deprecated long option parsing to just replace the word
in the list with the equivalent short option (-type -> -t) instead
of removing words from the list
- changed describe_command to take a single flags argument instead
of two int args; changed caller
- type now has two new options: -f suppresses function lookup (like
command), and -P forces a PATH search for the name(s)
builtins/common.h
- flags for describe_command are here
- changed extern declaration of describe_command
builtins/command.def
- changed call to describe_command to use flags from common.h, and
the right number of arguments
doc/{bash.1,bashref.texi}
- documented new -f and -P options to `type'
12/12
-----
lib/readline/rldefs.h
- fixed prototype for _rl_strnicmp
execute_cmd.c
- select_query now takes a new argument, an int flag saying whether
or not to print the menu the first time through the loop. An
empty line in response to the prompt will always cause the menu
to be reprinted
- changed execute_select_command to cause select_query to reprint
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
12/13
-----
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_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
12/17
-----
lib/readline/rlmbutil.h
- new file, place for multi-byte character defines and extern
declarations
lib/readline/{bind.c,readline.c,rlprivate.h}

- new code for multibyte characters, derived from IBM patch
lib/readline/readline.h
- include rltypedefs.h
12/19
-----
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
12/20
-----
lib/readline/rlmbutil.h, mbutil.c
- combined _rl_find_next_mbchar and _rl_find_next_nonzero_mbchar into
a single function
- combined _rl_find_prev_mbchar and _rl_find_prev_nonzero_mbchar into
a single function
lib/readline/{display,readline,vi_mode}.c
- changed callers of _rl_find_next_mbchar and
_rl_find_next_nonzero_mbchar

HAVE_STRUCT_TM_TM_ZONE, HAVE_STRFTIME
externs.h
- provide an extern declaration for strftime if HAVE_STRFTIME is
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
-----
configure.in
- use AC_HELP_STRING in AC_ARG_WITH and AC_ARG_ENABLE
- remove AC_ARG_ENABLE for largefile, since AC_SYS_LARGEFILE adds
one

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
- new file, string-to-[u]intmax_t conversion, just includes
fmtulong.c with the right defines

expr.c
- arithmetic is now in intmax_t instead of long

execute_cmd.c
- change shell_execve to make sure that the file is executable
before looking at the interpreter to find out why the execve()
failed (avoids misleading error message)
lib/glob/glob.c
- move code that matches leading `.' and skips those filenames into
a separate function: skipname(), so there can be unibyte and
multibyte versions of that function
1/7
---
subst.c
- more changes for multibyte characters
print_cmd.c
- change semicolon() so it doesn't output a `;' immediately after a
newline, since that results in a null command, which is a syntax
error
variables.c
- fix indirection_level_string to turn off set -x while evaluating
PS4
1/8
---
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 shell
include/posixdir.h

1/9
---
lib/glob/smatch.c
- new file, with strmatch (now xstrmatch) and associated functions,
with changes for multibyte chars
lib/glob/sm_loop.c
- new file, included by smatch.c, with `generic' versions of matching
functions that are compiled twice: once each for single-byte and
multibyte characters
lib/glob/strmatch.c
- strip out everything except strmatch(), which either calls fnmatch
(if HAVE_LIBC_FNM_EXTMATCH is defined) or xstrmatch
lib/glob/collsyms.c
- changes for multibyte chars
lib/glob/Makefile.in, Makefile.in
- changes for new source files
1/10
----
lib/readline/complete.c
- new function, rl_completion_mode (rl_command_func_t *func), returns
the appropriate value to pass to rl_complete_internal depending on
FUNC and the value of `show-all-if-ambiguous'. This allows
application completion functions to present the same interface as
rl_complete
lib/readline/readline.h
- new extern declaration for rl_completion_mode()
lib/readline/doc/rltech.texinfo
- documented rl_completion_mode
lib/readline/readline.[ch]
- bumped the version number to 4.3, changing the relevant cpp defines
configure.in
- require that an installed readline version be at least readline-4.3
bashline.c
- converted bash-specific completion functions to use
rl_completion_mode instead of passing TAB unconditionally
builtins/bashgetopt.c
- the `#' option specifier now means a required numeric argument,
not an optional one
builtins/type.def
- when converting [-]-{path,type,all} to -[pta], don't bother
freeing and reallocating the option string; just change opt[1]
and null opt[2]
lib/sh/snprintf.c
- support %ls/%S and %lc/%C for wide strings and characters,
respectively, if HANDLE_MULTIBYTE is defined
mailcheck.c
- don't print a message about new mail if the file has not grown,
even if the access time is less than the modification time
1/14
----
lib/readline/readline.c
- new function, rl_replace_line, to replace the readline line buffer
with the text supplied as an argument
- new function, rl_replace_from_history, replaces readline line
buffer with text from history entry passed as argument (undocumented,
not in readline.h because it requires a definition of
HIST_ENTRY for the prototype)
lib/readline/readlne.h
- new extern declaration for rl_replace_line
lib/readline/doc/rltech.texinfo
- documented rl_replace_line
lib/readline/{isearch,readline,search}.c

- broke the code that sets point after moving through the history
(_rl_history_preserve_point and _rl_history_saved_point) out
into a separate function, _rl_history_set_point()
lib/readline/{complete.c,rlprivate.h}
- find_completion_word -> _rl_find_completion_word
- free_match_list -> _rl_free_match_list
lib/readline/complete.c
- postprocess_matches and _rl_free_match_list now return immediately
if passed a null match list
variables.c
- new function, find_local_variable, finds a local variable by name
at the current variable context
- in find_variable_internal, call find_local_variable before searching
any of the temporary environments if variable_context > 0 (meaning
we're in a shell function). This lets a local variable
override a variable whose value was passed in the `function
environment'
1/15
----
variables.h, execute_cmd.c
- declare variables describing the temporary environments in
variables.h instead of in C files
findcmd.c, builtins/setattr.def
- instead of calling find_tempenv_variable, use find_variable_internal
and check whether the returned SHELL_VAR * has the tempvar
attribute
variables.c
- tentative change to lookup order in find_variable_internal so that
function local variables are found before variables in
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

Makefile.in
- link bashversion with buildversion.o instead of version.o, for
cross-compiling. version.o is for the target system;
buildversion.o is for the build system

to RUNNING, STOPPED, and DEADJOB defines for jobs
jobs.c
- use PS_RUNNING, PS_DONE, PS_STOPPED values for `running' field
of a PROCESS
- find_pipeline and find_job now take an additional flags argument
that, if non-zero, means to find only running processes; changed
all callers
- changed calls to find_pipeline and find_job made from waitchld
to find only running processes
- 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
find_pipeline immediately followed by find_job with the same PID
nojobs.c
- a couple of changes to make sure that set_pid_status is never
called with a pid argument of 0 or -1
trap.c
- change trap_handler to longjmp to wait_intr_buf (set by wait_builtin)
if a signal is received for which a trap has been set during
execution of the wait builtin (need to include builtins.h and
builtins/builtext.h and declare some extern variables for the
right things to check)
- new variable to keep track of which signal caused the longjmp to
wait_intr_buf, set by trap_handler (wait_signal_received)
builtins/wait.def
- set the return value of wait when a longjmp(wait_intr_buf, 1) is
done to 128 + wait_signal_received
{jobs,nojobs}.c
- set wait_signal_received to SIGINT in wait_sigint_handler before
the longjmp(wait_intr_buf, 1)

or very visible (overwrite mode)
lib/readline/readline.c
- new global variable, rl_insert_mode
- new function to toggle overwrite mode, rl_overwrite_mode
- each new line starts in insert mode
- switching to vi mode or emacs mode resets to insert mode
- reset cursor to normal before returning line
- _rl_replace_text now returns the number of characters inserted,
the return value from rl_insert_text
- new function, _rl_insert_or_replace_text (const char *string, int insert),
either inserts STRING or replaces the number of chars in STRING
with STRING starting at rl_point, depending on value of INSERT
- renamed rl_insert to _rl_insert_char, rl_insert just calls
_rl_insert_char with the same arguments when in insert mode
- new function, _rl_overwrite_char, handles self-insert in overwrite
mode. Does multibyte chars by reading an entire multibyte character
before entering overwrite loop
- new function, _rl_overwrite_rubout, handles RUBOUT when in
overwrite mode, called from rl_rubout

lib/readline/readline.c
- return 0 immediately from rl_insert_text if the string to insert
is NULL or ""
bashline.c
- if a numeric argument is given to one of the bash-specific glob
pattern completion functions (including TAB), append a `*' to
the word before generating matches
- in attempt_shell_completion, when doing glob completion, only
set the match list to NULL if rl_completion_type == TAB and
there is more than one completion. This permits listing completions
with double tabs and displaying ambiguous completions
- new function, bash_glob_complete_word, appends a `*' to the word
to be completed and then globs it. It uses a new filename
quoting function (bash_glob_quote_filename) to avoid quoting
globbing characters in the filename if there are no matches or
multiple matches
lib/readline/complete.c
- set completion_changed_buffer to 0 in rl_complete_internal if
no matches were produced by the completion generator function
- new variable, rl_completion_suppress_append, suppresses appending
of rl_completion_append_character. Settable by application
completion functions, always 0 when application completion
functions are called (set to 0 by rl_complete_internal and
rl_menu_complete)
- broke the code that assigns default values to readline completion
variables out of rl_complete_internal and rl_menu_complete into
a new function, set_completion_defaults (int what_to_do)
lib/readline/readline.h

with shell_variables as third argument
variables.h
- new struct var_context, variable context (per-scope -- global,
function local, etc.)
variables.[ch],builtins/common.[ch]
- moved functions that push and pop a variable context from
builtins/common.c to variables.c; move extern function
declarations to variables.h
- new function, all_local_variables
- variable_in_context is now static, used only by all_local_variables
variables.[ch],execute_cmd.c
- push_context now takes the function name as an argument for
future use
- push_context takes an indication of whether or not the function is
executing in a subshell and saves the positional parameters only
if not in a subshell
- new functions for managing a stack of variable contexts and
scopes: new_var_context, dispose_var_context, push_var_context,
pop_var_context, push_scope, pop_scope
builtins/declare.def
- call all_local_variables instead of map_over (...) in declare_internal
- don't call make_local_variable if we're looking at functions
((flags_on & att_function) != 0), since it's wasted
- make sure VAR is set to NULL if check for variable_context fails
and we didn't just create or fetch a local variable in
declare_internal
- in non-function branch of declare_internal, only call find_variable
if VAR is NULL -- if it's not null, we just created or fetched a
local variable and don't need to do it again

----
variables.[ch]
- the temporary environments (temporary_env, builtin_env, function_env)
are now HASH_TABLEs instead of argv-style arrays of strings (this
is an intermediate step on the way to the new lcc-inspired symbol
table scope structure)
- new internal attribute for variables: att_propagate. This means
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
- assign_in_env now adds to the HASH_TABLE temporary_env instead
of making environment-style strings in an array of strings
- changed the way the temporary environments are merged into the
shell variable table to account for the new HASH_TABLE temp
environments
- changed the way the export environment is created due to the new
structure of the temporary environments
- new function, bind_variable_internal (name, value, table), binds
NAME to have VALUE in TABLE without searching the temporary
environments
- removed: shell_var_from_env_string, bind_name_in_env_array
- variable_in_context now checks the att_local attribute and makes
sure the variable is not invisible
- local_and_exported now makes sure the variable is not invisible
execute_cmd.c
- we no longer need to copy the temporary environment to function_env
or builtin_env, we can simply use variable assignments
{findcmd,subst,variables}.c, builtins/{declare,setattr}.def
- since variables from the temporary environments are no longer turned
into SHELL_VARs on the fly, don't dispose the SHELL_VAR returned
by find_variable or find_variable_internal
- need to savestring() the value returned by find_variable if it has
the tempvar attribute before calling bind_variable on it, because
bind_variable will search and bind into the temporary environments
and will free the old value before binding the new. For temporary
environments, these two pointers will be the same, and
bind_tempenv_variable will end up using freed memory
builtins/{declare,setattr}.def
- set the att_propagate attribute when exporting or making readonly
variables from the temp environment (i.e., `var=value declare -x var'
or `var=value export var' sets the propagate attribute on the entry
for `var' in the temporary environment HASH_TABLE)
lib/readline/isearch.c

- make_new_variable now just calls new_shell_variable instead
of duplicating what it does
- removed some code in bind_function that duplicated what
new_variable does on the newly-created SHELL_VAR

made at the global scope), kill_all_local_variables() doesn't
need to consider functions

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
- some smaller code cleanups
- converted char_is_quoted(), unclosed_pair(), and skip_to_delim()
to understand multibyte characters

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

hash_table_nentries -> hash_size
copy_hash_table -> hash_copy
find_hash_item -> hash_search
remove_hash_item -> hash_remove
add_hash_item -> hash_insert
flush_hash_table -> hash_flush
dispose_hash_table -> hash_dispose
print_table_stats -> hash_pstats
get_hash_bucket -> hash_items
- changed hash_search to short-circuit if table->nentries == 0 and
HASH_CREATE has not been passed in the flags argument
{alias,variables,hashcmd,pcomplib}.c
- renamed calls to all renamed functions from hashlib.c
builtins/kill.def
- don't drop a leading `-' in a pid argument
- call kill_pid with an explicit third argument of 1 if the pid
argument to kill is < -1, rather than rely on the behavior of
kill(2)

subst.c
- quoted_strchr is no longer declared `inline'
- skip_double_quoted is no longer declared `inline'
- string_extract_double_quoted is no longer declared `inline'
lib/readline/input.c
- rl_gather_tyi is now an `int' valued function; returns the number
of characters read (0 or 1) or -1 on error
- if rl_gather_tyi() returns -1 to rl_read_key(), set rl_done to 1
and return a newline; something is wrong with the input fd
2/25
----
variables.[ch]
- IFS is now a special variable
- new special var function, sv_ifs(), called when IFS is set or unset
- call setifs() when IFS is first set in initialize_shell_variables
- call setifs() from make_local_variable and assign_in_env if
appropriate
- if assign_in_env() is called with a var assignment like `VAR=',
make the value in the new SHELL_VAR created be "" like
do_assignment_internal does, since certain parts of the shell use
a NULL value as evidence that the variable is unset (though
attributes may have been assigned)
- if push_temp_var pushes something up to the global_variables table,
make sure that the context is set to 0
- new function dispose_temporary_env, called by both
dispose_used_env_vars and merge_temporary_env with different `free
func' function pointers; calls sv_ifs after disposing the temporary
environment
- push_exported_var now calls bind_variable_internal instead of
bind_variable
- pop_scope and pop_context now call sv_ifs
subst.[ch]
- new global variables used to keep track of IFS state, to avoid
having to call find_variable("IFS") all the time:
ifs_var the SHELL_VAR for IFS
ifs_value ifs_var ? value_cell (ifs_var) : " \t\n"
ifs_cmap bitmap of characters in ifs_value
ifs_firstc first character in ifs_value
- new function setifs(), sets the aforementioned ifs variables each
time IFS is set or unset, and at nested scope exit
- instead of calling getifs() from inside subst.c, use ifs_value
- getifs() now just returns ifs_value
- use ifs_firstc in string_list_dollar_star()
- only call member() in issep() if separators is more than one char
- don't cache a bitmap every time expand_word_internal() is called;
use ifs_cmap instead
- new macro, isifs(c), checks whether C is in ifs_cmap
builtins/read.def
- use issep() and isifs() macros instead of looking at $IFS directly
syntax.h
- make sure macros that access sh_syntaxtab cast the argument to
`unsigned char' before array access
- new macros: issyntype(c, type) and notsyntype(c, type), check
sh_syntaxtab[c] for a particular flag value `type'
2/26
----
hashlib.h
- the `data' member of a `BUCKET_CONTENTS' is now a PTR_T
{hashlib,alias,variables,hashcmd,pcomplib}.c
- removed some casts when assigning to and using `data' member of a
`BUCKET_CONTENTS'
subst.c
- in split_at_delims, call make_word_list instead of allocating and
initializing a WORD_LIST * directly
make_cmd.[ch]
- add_string_to_list is now just a macro that calls make_word_list
- make_simple_command now calls make_word_list instead of allocating
a WORD_LIST * directly
2/27
----
copy_cmd.c
- copy_word now calls make_bare_word to allocate the copy
- copy_word_list now calls make_word_list to allocate the copy
shell.h
- include `ocache.h' for simple object caching
- call cmd_init() to initialize the WORD_DESC and WORD_LIST object
caches
{make,dispose}_cmd.c
- allocate WORD_DESC * and WORD_LIST * vars from their respective
ocaches, and return them to the cache when disposing
jobs.c
- renamed old `waiting_for_job' variable to `queue_sigchld', which
better reflects its intent: sigchld_handler does not call waitchld
if `queue_sigchld' is non-zero, it simply increments the count of
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
number of processes passed -- no reason to do it if they're the
same
2/28

sig.[ch]
- 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
- copy_simple_command: don't copy a null redirection list
subst.c
- in get_word_from_string and list_string, just check for " \t\n"
directly rather than calling strcmp
- in get_word_from_string and strip_trailing_ifs_whitespace, use
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

sig.h
- enclose the BLOCK_SIGNAL macro in a do {...} while (0) loop, at it
should have been all along
lib/readline/doc/rltech.texinfo
- document that readline defaults to stdin/stdout if rl_instream/
rl_outstream are NULL
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_func) to update the display, otherwise call
_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
if we're not echoing and the caller has defined a custom redisplay
function -- let the redisplay function deal with it
configure.in
- new option: --enable-mem-scramble, controls memory scrambling on
free() (on by default; only affects use of bash malloc)
config.h.in
- new option MEMSCRAMBLE, controlled by --enable-mem-scramble

parse.y
- added ksh-like behavior of [...] to read_token_word: if a `[' is
seen in an assignment context and the previous characters in the
token form a valid identifier, parse the [...] with
parse_matched_pair to allow spaces (and newlines) in the subscript
bashline.c
- new function bash_servicename_completion_function, for completing
service names from /etc/services
bashline.h

3/6
---
builtins/read.def
- change hard-coded `0' to new variable `fd' (initially 0) in
preparation for adding `-u fd' option
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

builtins/read.def
- only add the unwind_protect to free `rlbuf' if `edit' is non-zero,

redir.c
- small change to redirection_error() to make a slightly better
guess about the invalid file descriptor if the redirection op is
r_duplicating_input or r_duplicating_output
include/stdc.h
- new macro, SH_VA_START, to encapsulate the difference between
stdarg va_start and varargs va_start
{error,pcomplete,print_cmd}.c,builtins/common.c,lib/sh/snprintf.c
- use SH_VA_START

builtins/read.def
- support for the ksh-like `-u fd' option
general.c
- new function sh_validfd(fd), returns 1 if fd is a valid open file

bashline.c
- don't call posix_readline_initialize() from initialize_readline();
sv_strict_posix() should already have taken care of it

builtins/printf.def
- if the string argument to %q has non-printing characters, call
ansic_quote to quote it rather than sh_backslash_quote
variables.h
- new attribute: att_trace (and corresponding trace_p() macro).
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
builtins/setattr.def
- check for att_trace and output `-t' flag in show_var_attributes
execute_cmd.c
- if a function is being traced (it has the `-t' attribute set),
don't turn off the DEBUG trap when it executes
doc/{bash.1,bashref.texi}
- document the new `-t' option to declare/typeset
3/12
----
execute_cmd.c
- don't execute the debug trap in the `cm_simple:' case of
execute_command_internal; run it in execute_simple_command so we

are passed by the parser
redir.c

the right thing when executed
builtins/read.def
- print an error message and return failure immediately if zread/zreadc
return < 0
doc/{bash.1,bashref.texi}

lib/readline/isearch.c
- enabled code to allow chars bound to rl_rubout to delete characters

shell.c
- add `-l' invocation option to parse_shell_options; equivalent to
`--login'
- fixed set_login_shell to check first char of base pathname of argv0
for `-', like other shells
- move the check for make_login_shell after the call to
parse_shell_options because the `-l' option might set it
doc/{bash.1,bashref.texi}

array.c
- new function, array_shift, shifts an array left by a specified

- 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

lib/sh/stringvec.c, externs.h

examples/bashdb/bashdb
- new single-file version of bash debugger, originally modified from
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,
like ksh93 does
lib/readline/vi_mode.c
- redid rl_vi_subst (binding func for `s' and `S') in terms of
rl_vi_change_to: `S' == `cc' and `s' == `c '. This makes undo
work right

of breaking out of the current hash chain
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

- moved functions to lib/sh/stringvec.c
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
- ditto for strlist_from_word_list and strlist_to_word_list

externs.h
- new extern declarations for strvec_remove and strlist_remove

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

expanded string
- change ansiexpand() to call ansicstr with a `flags' parameter of 2

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

- don't need to free memory returned by get_array_value any more
subst.c
- quote_escapes 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
shell.c
- sh_exit is now compiled in; exit_shell calls sh_exit
error.c
- changed fatal_error, report_error, parser_error to call sh_exit

subst.[ch]
- changed Q_NOQUOTE to Q_PATQUOTE; it makes the intent more clear
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/malloc/{malloc,stats}.c
- moved declaration of _mstats to malloc.c so stats.o doesn't get
linked into the shell if the stats functions aren't called
4/2
---
lib/glob/smatch.c
- introduce `XCHAR' define, which is the type of arguments passed to
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
some compilers don't like `unsigned char *' initializers from
constant strings
[bash-2.05b-alpha1 released]

builtins/{evalstring.c,common.h}
- new flag for parse_and_execute, SEVAL_NOFREE, means to not free

variables.c
- var_lookup should use its `vcontext' argument instead of
unconditionally using `shell_variables'

builtins/bind.def,doc/{bash.1,bashref.texi}
- changed the usage summary and help text to make it clear that any
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
- new file, with zcatfd(int fd, int ofd, char *fn); dumps data from
FD to OFD
Makefile.in,lib/sh/Makefile.in
- added zcatfd.c, zcatfd.o member of libsh.a
builtins/evalstring.c
- changed cat_file to call zcatfd(fd, 1, fn)

`+' in the option string
- new variable, list_opttype, set to `-' or `+'
builtins/{common.c,{builtin,eval,exit,fg_bg,let,printf,pushd,return,source,wait}.def
- changes to allow a `--' option for every builtin that accepts
operands but not options, as per posix.1-2001
builtins/{declare,setattr}.def
- use internal_getopt for parsing options, now that it supports `+'
builtins/set.def
- use internal_getopt for initial option parse, now that it supports
a leading `+'
{configure,Makefile}.in, builtins/{Makefile.in,help.def,mkbuiltins.c}
- support for a new configure option, ``--enable-separate-helpfiles'',
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

lib/malloc/imalloc.h
- added some macros derived from dlmalloc and glibc malloc to inline
memcpy and memset if the requested size is <= 32 bytes
lib/malloc/malloc.c
- use MALLOC_MEMSET instead of memset in internal_{malloc,free}
include/ocache.h
- use OC_MEMSET (variant of MALLOC_MEMSET) in ocache_free
configure.in, config.h.in
- check for getservent(), define HAVE_GETSERVENT if found
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 number of strlen(3) calls
subst.c
- change callers of macros in shmbutil.h to add extra argument as

lib/sh/strtrans.c
- when ansicstr is parsing a format string for `echo -e' (or the
