This document details the changes between this version, bash-4.0-beta,
|
||||
and the previous version, bash-4.0-alpha.
|
||||
|
||||
1. Changes to Bash
|
||||
|
||||
a. Fixed a typo that caused a variable to be used before initialization
|
||||
while parsing Posix-style command substitutions.
|
||||
|
||||
b. Fixed a bug that caused stray ^? when the expansion of a parameter used
|
||||
as part of a pattern removal expansion is empty, but part of a non-
|
||||
empty string.
|
||||
|
||||
c. Fixed a bug that could cause strings not converted to numbers by strtol
|
||||
to be treated as if the conversion had been successful.
|
||||
|
||||
d. The `return' builtin now accepts no options and requires a `--' before
|
||||
a negative return value, as Posix requires.
|
||||
|
||||
e. Fixed a bug that caused local variables to be created with the empty
|
||||
string for a value rather than no value.
|
||||
|
||||
f. Changed behavior so the shell now acts as if it received an interrupt
|
||||
when a pipeline is killed by SIGINT while executing a list.
|
||||
|
||||
g. Fixed a bug that caused `declare var' and `typeset var' to initialize
|
||||
`var' to the empty string.
|
||||
|
||||
h. Changed `bind' builtin to print a warning but proceed if invoked when
|
||||
line editing is not active.
|
||||
|
||||
i. Fixed a bug that caused the shell to exit when the `errexit' option is
|
||||
set and a command in a pipeline returns a non-zero exit status.
|
||||
|
||||
j. Fixed a bug that caused the shell to not run the exit trap in a command
|
||||
run with `bash -c' under some circumstances.
|
||||
|
||||
k. Fixed a bug that caused parser errors to occasionally not set $? when
|
||||
running commands with `eval'.
|
||||
|
||||
l. Fixed a bug that caused stray control characters when evaluating compound
|
||||
array assignments containing $'\x7f' escapes.
|
||||
|
||||
m. Fixed a bug that caused redirections involving file descriptor 10 as the
|
||||
target to behave incorrectly.
|
||||
|
||||
n. Fixed a bug that could cause memory to be freed multiple times when
|
||||
assigning to COMP_WORDBREAKS.
|
||||
|
||||
2. Changes to Readline
|
||||
|
||||
3. New Features in Bash
|
||||
|
||||
a. 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.
|
||||
|
||||
b. CDPATH and GLOBIGNORE are ignored when the shell is running in privileged
|
||||
mode.
|
||||
|
||||
c. 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.
|
||||
|
||||
d. 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.
|
||||
|
||||
4. New Features in Readline
|
||||
|
||||
a. If the kernel supports it, readline displays special characters
|
||||
corresponding to a keyboard-generated signal when the signal is received.
