This document details the changes between this version, bash-4.0-release,
|
||||
and the previous version, bash-4.0-rc1.
|
||||
|
||||
1. Changes to Bash
|
||||
|
||||
a. Changed the message printed when setlocale(3) fails to only include the
|
||||
strerror error text if the call changes errno.
|
||||
|
||||
b. Changed trap command execution to reset the line number before running a
|
||||
trap (except DEBUG and RETURN traps).
|
||||
|
||||
c. Fixed behavior of case-modifiying word expansions to not work on
|
||||
individual words within a variable's value.
|
||||
|
||||
d. Fixed a bug that caused mapfile to not be interruptible when run in an
|
||||
interactive shell.
|
||||
|
||||
e. Fixed a bug that caused mapfile to not run callbacks for the first line
|
||||
read.
|
||||
|
||||
f. Fixed a bug that caused mapfile to not honor EOF typed in an interactive
|
||||
shell.
|
||||
|
||||
g. Fixed the coprocess reaping code to not run straight from a signal handler.
|
||||
|
||||
h. Fixed a bug that caused printf -b to ignore the first % conversion specifier
|
||||
in the format string on 64-bit systems.
|
||||
|
||||
i. Fixed a bug that caused incorrect word splitting when `:', `=', or `~'
|
||||
appeared in $IFS.
|
||||
|
||||
j. Fixed a bug that caused data corruption in the programmable completion code
|
||||
when a shell function called from a completion aborted execution.
|
||||
|
||||
k. Fixed a bug that caused the CPU usage reported by the `time' builtin to be
|
||||
capped at 100%.
|
||||
|
||||
l. Changed behavior of shell when -e option is in effect to reflect consensus
|
||||
of Posix shell standardization working group.
|
||||
|
||||
m. Fixed a bug introduced in bash-4.0-alpha that caused redirections to not
|
||||
be displayed by `type' or `declare' when appearing in functions under
|
||||
certain circumstances.
|
||||
|
||||
2. Changes to Readline
|
||||
|
||||
a. Fixed a bug that caused !(...) extended glob patterns to inhibit later
|
||||
history expansion.
|
||||
|
||||
b. Reworked the signal handling to avoid calling disallowed functions from a
|
||||
signal handler.
|
||||
|
||||
3. New Features in Bash
|
||||
|
||||
a. `readarray' is now a synonym for `mapfile'.

41. Beginning with bash-4.0, when one of the commands in a pipeline is killed
|
||||
by a SIGINT while executing a command list, the shell acts as if it
|
||||
received the interrupt.
|
||||
|
||||
42. Bash-4.0 changes the handling of the set -e option so that the shell exits
|
||||
if a pipeline fails (and not just if the last command in the failing
|
||||
pipeline is a simple command). This is not as Posix specifies. There is
|
||||
work underway to update this portion of the standard; the bash-4.0
|
||||
behavior attempts to capture the consensus at the time of release.

---
|
||||
locale.c
|
||||
- since setlocale() doesn't set errno to anything meaningful,
|
||||
don't include the strerror() result in the error message if
|
||||
it fails
|
||||
- make sure the error messages printed when setlocale fails are
|
||||
localizable

|

lib/readline/histexpand.c
|
||||
- make sure that every time history_no_expand_chars is tested, we
|
||||
also call the history_inhibit_expansion_function if it's set.
|

Fixes bug reported by Yang Zhang <yanghatespam@gmail.com>

----
|
||||
trap.c
|
||||
- make sure to call parse_and_execute with the SEVAL_RESETLINE bit
|
||||
set in the flags so it will reset the line number when running
|
||||
the trap commands. Partial fix for bug reported by
|
||||
peter360@fastmail.us
|
||||
|
||||
1/14
|
||||
----
|
||||
builtins/reserved.def
|
||||
- document `coproc' so it can be used with `help' builtin. Pointed
|
||||
out by Pierre Gaston <pgas@freeshell.org>
|
||||
|
||||
lib/sh/casemod.c
|
||||
- added two new flags: CASE_UPFIRST and CASE_LOWFIRST to casemod
|
||||
the first character of the passed string and pass the rest
|
||||
through unchanged. Fixes bug reported by Jan Schampera
|
||||
<jan.schampera@web.de>
|
||||
|
||||
externs.h
|
||||
- new defines for CASE_UPFIRST and CASE_LOWFIRST
|
||||
|
||||
subst.c
|
||||
- use CASE_UPFIRST for ^ and CASE_LOWFIRST for , casemod operators
|
||||
|
||||
builtins/mapfile.def
|
||||
- call zreset() before calling first zgetline(), to clean out any
|
||||
remaining data in local buffer used by zreadc. Fixes bug
|
||||
reported by Pierre Gaston <pierre.gaston@gmail.com>
|
||||

|
||||
----
|
||||
lib/sh/zread.c
|
||||
- renamed zreadintr to zreadretry -- not perfect, but better
|
||||
- new functions: zreadintr, which just calls read so it can be
|
||||
interruptible, and zreadcintr, which is like zreadc but uses
|
||||
zreadintr to fill the buffer
|
||||
|
||||
lib/sh/zgetline.c
|
||||
- in zgetline, when zread/zreadc return <= 0, make sure line is
|
||||
non-null before assigning to line[nr]
|
||||
|
||||
builtins/mapfile.def
|
||||
- return an error right away if the supplied array variable name
|
||||
refers to a readonly or noassign array
|
||||
- set interrupt_immediately so calls to zgetline can be
|
||||
interrupted. Fixes bug reported by Pierre Gaston
|
||||
<pierre.gaston@gmail.com>
|
||||
- if interactive, pass the SEVAL_INTERACT and SEVAL_NOHIST flags
|
||||
to parse_and_execute when calling callbacks. Fixes bug reported
|
||||
by Pierre Gaston <pierre.gaston@gmail.com>
|
||||
- add `readarray' as a synonym for mapfile
|
||||
|
||||
doc/{bash.1,bashref.texi}
|
||||
- document behavior of mapfile builtin adding index of array element
|
||||
to be assigned as additional argument to callback string. Reported
|
||||
by Pierre Gaston <pierre.gaston@gmail.com>
|
||||
- document readarray as synonym for mapfile
|
||||
|
||||
builtins/common.c
|
||||
- new error function, sh_ttyerror(set), prints an error message having
|
||||
to do with setting or getting terminal attributes
|
||||
|
||||
builtins/read.def
|
||||
- print error message if read fails to set terminal attributes
|
||||
|
||||

----
|
||||
execute_cmd.c
|
||||
- new function, coproc_reap, calls coproc_dispose if sh_coproc is
|
||||
marked as COPROC_DEAD
|
||||
- new function, cpl_reap, disposes coprocs marked as COPROC_DEAD
|
||||
from coproc list
|
||||
- change coproc_pidchk to just mark the coproc as dead instead of
|
||||
calling coproc_dispose, so we don't call unsafe functions from
|
||||
a signal handler. Fixes bug reported by Andreas Schwab
|
||||
<schwab@suse.de>
|
||||
|
||||
execute_cmd.h
|
||||
- new extern declaration for coproc_reap
|
||||
|
||||
command.h
|
||||
- new flags for c_flags member of a struct coproc
|
||||
|
||||
{jobs,nojobs}.c
|
||||
- add call to coproc_reap in cleanup_dead_jobs, which will do the
|
||||
right queueing or blocking of SIGCHLD
|
||||
|
||||
trap.c
|
||||
- modify change from 1/12 to not reset the line number when running
|
||||
the DEBUG and RETURN traps
|
||||
|
||||
1/18
|
||||
----
|
||||
lib/sh/casemod.c
|
||||
- change default operations to work on entire passed string instead
|
||||
of breaking into words at non-alpha-numerics. Use new
|
||||
CASE_USEWORDS flag to enable by-word behavior. Fixes bug reported
|
||||
by Jan Schampera <jan.schampera@web.de>
|
||||
|
||||
builtins/printf.def
|
||||
- in vbprintf, bracket each call to vsnprintf (which uses the args
|
||||
passed to vbprintf) with SH_VA_START and va_end, so we can
|
||||
reninitialize the argument list for each call. This is actually
|
||||
what the C standard requires. Fixes bug that caused printf -b
|
||||
to `ignore' first % format specifier if it came first in the
|
||||
string. Reported by David Leverton <levertond@googlemail.com>
|
||||
|
||||
builtins/mapfile.def
|
||||
- start the line count at 1, since it doesn't get incremented before
|
||||
(or after) reading the first line, so things like
|
||||
`mapfile -n 5 -c 1 -C 'echo foo' array < file' work right and call
|
||||
the callback after the first line is read. Fixes bug reported by
|
||||
Pierre Gaston <pierre.gaston@gmail.com>
|
||||
|
||||

|
||||
lib/readline/complete.c
|
||||
- set _rl_interrupt_immediately non-zero before reading from the file
|
||||
system or calling an application-defined completion function
|
||||
|
||||
lib/readline/signals.c
|
||||
- renamed rl_signal_handler to _rl_handle_signal; new version of
|
||||
rl_signal_handler that just calls _rl_handle_signal (for now)
|
||||
- new function _rl_signal_handler that calls _rl_handle_signal without
|
||||
any checking
|
||||
|
||||
lib/readline/rlprivate.h
|
||||
- new extern declaration for _rl_signal_handler
|
||||
- new define, RL_CHECK_SIGNALS, checks whether or not _rl_caught_signal
|
||||
is set and calls _rl_signal_handler if so
|
||||
|
||||
lib/readline/{bind,input,readline}.c
|
||||
- add RL_CHECK_SIGNALS in appropriate places
|
||||
|
||||
lib/readline/signals.c
|
||||
- change rl_signal_handler to set a flag and return rather than
|
||||
run through the entire signal handling process. If
|
||||
_rl_interrupt_immediately is set, call the signal handling code
|
||||
right away instead of setting the flag. Initial fix for crash
|
||||
bug reported by Roman Rakus <rrakus@redhat.com>
|
||||
|
||||
aclocal.m4
|
||||
- new macro, BASH_TYPE_SIG_ATOMIC_T, tests for sig_atomic_t in
|
||||
<signal.h>, defines as int if not defined
|
||||
|
||||
configure.in
|
||||
- call BASH_TYPE_SIG_ATOMIC_T
|
||||
- call AC_C_VOLATILE
|
||||
|
||||
config.h.in
|
||||
- empty define for sig_atomic_t
|
||||
- empty define for volatile
|
||||
|
||||

|
||||
----
|
||||
subst.c
|
||||
- audit calls to add_character and change to add_ifs_character (which
|
||||
quotes characters in $IFS). Affects primarily `:', `=', and `~'.
|
||||
Fixes bug reported by Jan Schampera <jan.schampera@web.de>; fix

throw_to_top_level is called. Bug report and fix from
|
||||
werner@suse.de.
|
||||
|
||||
execute_cmd.c
|
||||
- don't clamp CPU usage at 100% in print_formatted_time. Bug reported
|

by Linda Walsh <bash@tlinx.org>
|
||||
|
||||

|

---
|
||||
locale.c
|
||||
- in set_locale_var, set errno to 0 before calling setlocale(), and
|
||||
print strerror (errno) if setlocale fails and errno ends up non-zero
|
||||
|
||||
2/6
|

---
|
||||
configure.in
|
||||
- backed out of solaris change from 10/23/2008 (adding `-z interpose'
|
||||
to LDFLAGS) due to solaris updates to fix a linker problem.

----
|
||||
execute_cmd.c
|
||||
- change execute_connection so failure of a pipeline will cause the
|
||||
shell to exit if -e is on. From discussion on austin-group
|
||||
mailing list
|
||||
- change execute_command_internal so failure of a user-specified
|
||||
subshell will cause the shell to exit if -e is on. From discussion
|

|
||||
implementation
|

----
|
||||
print_cmd.c
|
||||
- fix print_deferred_heredocs to not print a space if the separator
|
||||
string is null
|
||||
- change print_deferred_heredocs to set `was_heredoc' after printing
|
||||
something
|
||||
- change connection printing code to only print the `;' separator
|
||||
if we haven't just printed a here-document
|
||||
- change connection printing code to print any deferred here
|
||||
documents after the rhs of the connection. Fixes bug reported by

Bash-3.2 is the second maintenance release of the third major release of
|
||||
bash. It contains the following significant new features (see the manual
|
||||
page for complete descriptions and the CHANGES and NEWS files in the
|
||||
bash-3.2 distribution).
|
||||
Bash-4.0 is the fourth major release of bash. There are numerous new features,
|
||||
some experimental. Depending on community reception, the experimental
|
||||
features will evolve.
|
||||
|
||||
Bash-4.0 contains the following new features (see the manual page for
|
||||
complete descriptions and the CHANGES and NEWS files in the bash-4.0
|
||||
distribution):
|
||||
|
||||
o When using substring expansion on the positional parameters, a starting
|
||||
index of 0 now causes $0 to be prefixed to the list.
|
||||
|
||||
o There is a new variable, $BASHPID, which always returns the process id of
|
||||
the current shell.
|
||||
|
||||
o There is a new `autocd' option that, when enabled, causes bash to attempt
|
||||
to `cd' to a directory name that is supplied as the first word of a
|
||||
simple command.
|
||||
|
||||
o There is a new `checkjobs' option that causes the shell to check for and
|
||||
report any running or stopped jobs at exit.
|
||||
|
||||
o The programmable completion code exports a new COMP_TYPE variable, set to
|
||||
a character describing the type of completion being attempted.
|
||||
|
||||
o The programmable completion code exports a new COMP_KEY variable, set to
|
||||
the character that caused the completion to be invoked (e.g., TAB).
|
||||
|
||||
o The programmable completion code now uses the same set of characters as
|
||||
readline when breaking the command line into a list of words.
|
||||
|
||||
o The block multiplier for the ulimit -c and -f options is now 512 when in
|
||||
Posix mode, as Posix specifies.
|
||||
|
||||
o Changed the behavior of the read builtin to save any partial input received
|
||||
in the specified variable when the read builtin times out. This also
|
||||
results in variables specified as arguments to read to be set to the empty
|
||||
string when there is no input available. When the read builtin times out,
|
||||
it returns an exit status greater than 128.
|
||||
|
||||
o The shell now has the notion of a `compatibility level', controlled by
|
||||
new variables settable by `shopt'. Setting this variable currently
|
||||
restores the bash-3.1 behavior when processing quoted strings on the rhs
|
||||
of the `=~' operator to the `[[' command.
|
||||
|
||||
o The `ulimit' builtin now has new -b (socket buffer size) and -T (number
|
||||
of threads) options.
|
||||
|
||||
o There is a new `compopt' builtin that allows completion functions to modify
|
||||
completion options for existing completions or the completion currently
|
||||
being executed.
|
||||
|
||||
o The `read' builtin has a new -i option which inserts text into the reply
|
||||
buffer when using readline.
|
||||
|
||||
o A new `-E' option to the complete builtin allows control of the default
|
||||
behavior for completion on an empty line.
|
||||
|
||||
o There is now limited support for completing command name words containing
|
||||
globbing characters.
|
||||
|
||||
o The `help' builtin now has a new -d option, to display a short description,
|
||||
and a -m option, to print help information in a man page-like format.
|
||||
|
||||
o There is a new `mapfile' builtin to populate an array with lines from a
|
||||
given file.
|
||||
|
||||
o If a command is not found, the shell attempts to execute a shell function
|
||||
named `command_not_found_handle', supplying the command words as the
|
||||
function arguments.
|
||||
|
||||
o There is a new shell option: `globstar'. When enabled, the globbing code
|
||||
treats `**' specially -- it matches all directories (and files within
|
||||
them, when appropriate) recursively.
|
||||
|
||||
o There is a new shell option: `dirspell'. When enabled, the filename
|
||||
completion code performs spelling correction on directory names during
|
||||
completion.
|
||||
|
||||
o The `-t' option to the `read' builtin now supports fractional timeout
|
||||
values.
|
||||
|
||||
o Brace expansion now allows zero-padding of expanded numeric values and
|
||||
will add the proper number of zeroes to make sure all values contain the
|
||||
same number of digits.
|
||||
|
||||
o There is a new bash-specific bindable readline function: `dabbrev-expand'.
|
||||
It uses menu completion on a set of words taken from the history list.
|
||||
|
||||
o The command assigned to a key sequence with `bind -x' now sets two new
|
||||
variables in the environment of the executed command: READLINE_LINE_BUFFER
|
||||
and READLINE_POINT. The command can change the current readline line
|
||||
and cursor position by modifying READLINE_LINE_BUFFER and READLINE_POINT,
|
||||
respectively.
|
||||
|
||||
o There is a new >>& redirection operator, which appends the standard output
|
||||
and standard error to the named file.
|
||||
|
||||
o The parser now understands `|&' as a synonym for `2>&1 |', which redirects
|
||||
the standard error for a command through a pipe.
|
||||
|
||||
o The new `;&' case statement action list terminator causes execution to
|
||||
continue with the action associated with the next pattern in the
|
||||
statement rather than terminating the command.
|
||||
|
||||
o The new `;;&' case statement action list terminator causes the shell to
|
||||
test the next set of patterns after completing execution of the current
|
||||
action, rather than terminating the command.
|
||||
|
||||
o The shell understands a new variable: PROMPT_DIRTRIM. When set to an
|
||||
integer value greater than zero, prompt expansion of \w and \W will
|
||||
retain only that number of trailing pathname components and replace
|
||||
the intervening characters with `...'.
|
||||
|
||||
o There are new case-modifying word expansions: uppercase (^[^]) and
|
||||
lowercase (,[,]). They can work on either the first character or
|
||||
array element, or globally. They accept an optional shell pattern
|
||||
that determines which characters to modify. There is an optionally-
|
||||
configured feature to include capitalization operators.
|
||||
|
||||
o The shell provides associative array variables, with the appropriate
|
||||
support to create, delete, assign values to, and expand them.
|
||||
|
||||
o The `declare' builtin now has new -l (convert value to lowercase upon
|
||||
assignment) and -u (convert value to uppercase upon assignment) options.
|
||||
There is an optionally-configurable -c option to capitalize a value at
|
||||
assignment.
|
||||
|
||||
o There is a new `coproc' reserved word that specifies a coprocess: an
|
||||
asynchronous command run with two pipes connected to the creating shell.
|
||||
Coprocs can be named. The input and output file descriptors and the
|
||||
PID of the coprocess are available to the calling shell in variables
|
||||
with coproc-specific names.
|
||||
|
||||
o A value of 0 for the -t option to `read' now returns success if there is
|
||||
input available to be read from the specified file descriptor.
|
||||
|
||||
o CDPATH and GLOBIGNORE are ignored when the shell is running in privileged
|
||||
mode.
|
||||
|
||||
o New bindable readline functions shell-forward-word and shell-backward-word,
|
||||
which move forward and backward words delimited by shell metacharacters
|
||||
and honor shell quoting.
|
||||
|
||||
o New bindable readline functions shell-backward-kill-word and shell-kill-word
|
||||
which kill words backward and forward, but use the same word boundaries
|
||||
as shell-forward-word and shell-backward-word.

|

bbaasshhbbuugg is a shell script to help the user compose and mail bug reports
|
||||
concerning bash in a standard format. bbaasshhbbuugg invokes the editor spec-
|
||||
ified by the environment variable EEDDIITTOORR on a temporary copy of the bug
|
||||
report format outline. The user must fill in the appropriate fields and
|
||||
exit the editor. bbaasshhbbuugg then mails the completed report to _b_u_g_-
|
||||
_b_a_s_h_@_g_n_u_._o_r_g, or _e_m_a_i_l_-_a_d_d_r_e_s_s. If the report cannot be mailed, it is
|
||||
saved in the file _d_e_a_d_._b_a_s_h_b_u_g in the invoking user's home directory.
|
||||
|
||||
The bug report format outline consists of several sections. The first
|
||||
section provides information about the machine, operating system, the
|
||||
bash version, and the compilation environment. The second section
|
||||
should be filled in with a description of the bug. The third section
|
||||
should be a description of how to reproduce the bug. The optional
|
||||
fourth section is for a proposed fix. Fixes are encouraged.

|

bbaasshhbbuugg will utilize the following environment variables if they exist:

EEDDIITTOORR Specifies the preferred editor. If EEDDIITTOORR is not set, bbaasshhbbuugg

rbash - restricted bash, see bbaasshh(1)
|
||||

||||
RREESSTTRRIICCTTEEDD SSHHEELLLL
|
||||
If bbaasshh is started with the name rrbbaasshh, or the --rr option is supplied at
|
||||
invocation, the shell becomes restricted. A restricted shell is used
|
||||
to set up an environment more controlled than the standard shell. It
|
||||
behaves identically to bbaasshh with the exception that the following are
|
||||
disallowed or not performed:
|
||||
|
||||
+o changing directories with ccdd
|
||||
|
||||
+o setting or unsetting the values of SSHHEELLLL, PPAATTHH, EENNVV, or BBAASSHH__EENNVV
|
||||
|
||||
+o specifying command names containing //
|
||||
|
||||
+o specifying a file name containing a // as an argument to the ..
|
||||
builtin command
|
||||
|
||||
+o Specifying a filename containing a slash as an argument to the
|
||||
--pp option to the hhaasshh builtin command
|
||||
|
||||
+o importing function definitions from the shell environment at
|
||||
startup
|
||||
|
||||
+o parsing the value of SSHHEELLLLOOPPTTSS from the shell environment at
|
||||
startup
|
||||
|
||||
+o redirecting output using the >, >|, <>, >&, &>, and >> redirect-
|
||||
ion operators
|
||||
|
||||
+o using the eexxeecc builtin command to replace the shell with another
|
||||
command
|
||||
|
||||
+o adding or deleting builtin commands with the --ff and --dd options
|
||||
to the eennaabbllee builtin command
|
||||
|
||||
+o Using the eennaabbllee builtin command to enable disabled shell
|
||||
builtins
|
||||
|
||||
+o specifying the --pp option to the ccoommmmaanndd builtin command
|
||||
|
||||
+o turning off restricted mode with sseett ++rr or sseett ++oo rreessttrriicctteedd.
|
||||
|
||||
These restrictions are enforced after any startup files are read.
|
||||
|
||||
When a command that is found to be a shell script is executed, rrbbaasshh
|
||||
turns off any restrictions in the shell spawned to execute the script.
