This document details the changes between this version, bash-3.2-release,
|
||||
and the previous version, bash-3.2-beta.
|
||||
|
||||
1. Changes to Bash
|
||||
|
||||
a. Fixed a bug that caused the temporary environment passed to a command to
|
||||
affect the shell's environment under certain circumstances.
|
||||
|
||||
b. Fixed a bug in the printf builtin that caused the %q format specifier to
|
||||
ignore empty string arguments.
|
||||
|
||||
c. Improved multibyte character environment detection at configuration time.
|
||||
|
||||
d. Fixed a bug in the read builtin that left spurious escape characters in the
|
||||
input after processing backslashes when assigning to an array variable.
|
||||
|
||||
2. Changes to Readline
|
||||
|
||||
a. Fixed a redisplay bug that occurred in multibyte-capable locales when the
|
||||
prompt was one character longer than the screen width.
|
||||
------------------------------------------------------------------------------
|
||||
This document details the changes between this version, bash-3.2-beta,
|
||||
and the previous version, bash-3.2-alpha.
|
||||
|
||||
1. Changes to Bash
|
||||
|
||||
a. Changed the lexical analyzer to treat locale-specific blank characters as
|
||||
white space.
|
||||
|
||||
b. Fixed a bug in command printing to avoid confusion between redirections and
|
||||
process substitution.
|
||||
|
||||
c. Fixed problems with cross-compiling originating from inherited environment
|
||||
variables.
|
||||
|
||||
d. Added write error reporting to printf builtin.
|
||||
|
||||
e. Fixed a bug in the variable expansion code that could cause a core dump in
|
||||
a multi-byte locale.
|
||||
|
||||
f. Fixed a bug that caused substring expansion of a null string to return
|
||||
incorrect results.
|
||||
|
||||
g. BASH_COMMAND now retains its previous value while executing commands as the
|
||||
result of a trap, as the documentation states.
|
||||
|
||||
2. Changes to Readline
|
||||
|
||||
a. Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
|
||||
the prompt and input line multiple times.
|
||||
|
||||
b. Fixed history expansion to not be confused by here-string redirection.
|
||||
|
||||
c. Readline no longer treats read errors by converting them to newlines, as
|
||||
it does with EOF. This caused partial lines to be returned from readline().

||||

|

This document details the changes between this version, bash-3.2-alpha,
|
||||
and the previous version, bash-3.1-release.
|
||||
|
||||
1. Changes to Bash
|
||||
|
||||
a. Fixed a source bug that caused the minimal configuration to not compile.
|
||||
|
||||
b. Fixed memory leaks in error handling for the `read' builtin.
|
||||
|
||||
c. Changed the [[ and (( compound commands to set PIPESTATUS with their exit
|
||||
status.
|
||||
|
||||
d. Fixed some parsing problems with compound array assignments.
|
||||
|
||||
e. Added additional configuration changes for: NetBSD (incomplete multibyte
|
||||
character support)
|
||||
|
||||
f. Fixed two bugs with local array variable creation when shadowing a variable
|
||||
of the same name from a previous context.
|
||||
|
||||
g. Fixed the `read' builtin to restore the correct set of completion functions
|
||||
if a timeout occurs.
|
||||
|
||||
h. Added code to defer the initialization of HISTSIZE (and its stifling of the
|
||||
history list) until the history file is loaded, allowing a startup file to
|
||||
override the default value.
|
||||
|
||||
i. Tightened up the arithmetic expression parsing to produce better error
|
||||
messages when presented with invalid operators.
|
||||
|
||||
j. Fixed the cross-compilation support to build the signal list at shell
|
||||
invocation rather than compile time if cross-compiling.
|
||||
|
||||
k. Fixed multibyte support for non-gcc compilers (or compilers that do not
|
||||
allow automatic array variable sizing based on a non-constant value).
|
||||
|
||||
l. Several fixes to the code that manages the list of terminated jobs and
|
||||
their exit statuses, and the list of active and recently-terminated jobs
|
||||
to avoid pid aliasing/wraparound and allocation errors.
|
||||
|
||||
m. Fixed a problem that allowed scripts to die due to SIGINT while waiting
|
||||
for children, even when started in the background or otherwise ignoring
|
||||
SIGINT.
|
||||
|
||||
n. Fixed a bug that caused shells invoked as -/bin/bash from not being
|
||||
recognized as login shells.
|
||||
|
||||
o. Fixed a problem that caused shells in the background to give the terminal
|
||||
to a process group other than the foreground shell process group.
|
||||
|
||||
p. Fixed a problem with extracting the `varname' in ${#varname}.
|
||||
|
||||
q. Fixed the code that handles SIGQUIT to not exit immediately -- thereby
|
||||
calling functions that may not be called in a signal handler context --
|
||||
but set a flag and exit afterward (like SIGINT).
|
||||
|
||||
r. Changed the brace expansion code to skip over braces that don't begin a
|
||||
valid matched brace expansion construct.
|
||||
|
||||
s. Fixed `typeset' and `declare' to not require that their shell function
|
||||
operands to be valid shell identifiers.
|
||||
|
||||
t. Changed `test' to use access(2) with a temporary uid/euid swap when testing
|
||||
file attributes and running setuid, and access(2) in most other cases.
|
||||
|
||||
u. Changed completion code to not attempt command name completion on a line
|
||||
consisting solely of whitespace when no_empty_command_completion is set.
|
||||
|
||||
v. The `hash' builtin now prints nothing in posix mode when the hash table is
|
||||
empty, and prints a message to that effect to stdout instead of stderr
|
||||
when not in posix mode.
|
||||
|
||||
w. Fixed a bug in the extended pattern matching code that caused it to fail to
|
||||
match periods with certain patterns.
|
||||
|
||||
x. Fixed a bug that caused the shell to dump core when performing filename
|
||||
generation in directories with thousands of files.
|
||||
|
||||
y. Returned to the original Bourne shell rules for parsing ``: no recursive
|
||||
parsing of embedded quoted strings or ${...} constructs.
|
||||
|
||||
z. The inheritence of the DEBUG, RETURN, and ERR traps is now dependent only
|
||||
on the settings of the `functrace' and `errtrace' shell options, rather
|
||||
than whether or not the shell is in debugging mode.
|
||||
|
||||
aa. Fixed a problem with $HOME being converted to ~ in the expansion of
|
||||
members of the DIRSTACK array.
|
||||
|
||||
bb. Fixed a problem with quoted arguments to arithmetic expansions in certain
|
||||
constructs.
|
||||
|
||||
cc. The command word completion code now no longer returns matching directories
|
||||
while searching $PATH.
|
||||
|
||||
dd. Fixed a bug with zero-padding and precision handling in snprintf()
|
||||
replacement.
|
||||
|
||||
ee. Fixed a bug that caused the command substitution code not to take embedded
|
||||
shell comments into account.
|
||||
|
||||
ff. Fixed a bug that caused $((...);(...)) to be misinterpreted as an
|
||||
arithmetic substitution.
|
||||
|
||||
gg. Fixed a bug in the prompt expansion code that inappropriately added a
|
||||
\001 before a \002 under certain circumstances.
|
||||
|
||||
hh. Fixed a bug that caused `unset LANG' to not properly reset the locale
|
||||
(previous versions would set the locale back to what it was when bash
|
||||
was started rather than the system's "native" locale).
|
||||
|
||||
ii. Fixed a bug that could cause file descriptors > 10 to not be closed even
|
||||
when closed explicitly by a script.
|
||||
|
||||
jj. Fixed a bug that caused single quotes to be stripped from ANSI-C quoting
|
||||
inside double-quoted command substitutions.
|
||||
|
||||
kk. Fixed a bug that could cause core dumps when `return' was executed as the
|
||||
last element of a pipeline inside a shell function.
|
||||
|
||||
ll. Fixed a bug that caused DEBUG trap strings to overwrite commands stored in
|
||||
the jobs list.
|
||||
|
||||
2. Changes to Readline
|
||||
|
||||
a. Fixed a problem that caused segmentation faults when using readline in
|
||||
callback mode and typing consecutive DEL characters on an empty line.
|
||||
|
||||
b. Fixed several redisplay problems with multibyte characters, all having to
|
||||
do with the different code paths and variable meanings between single-byte
|
||||
and multibyte character redisplay.
|
||||
|
||||
c. Fixed a problem with key sequence translation when presented with the
|
||||
sequence \M-\C-x.
|
||||
|
||||
d. Fixed a problem that prevented the `a' command in vi mode from being
|
||||
undone and redone properly.
|
||||
|
||||
e. Fixed a problem that prevented empty inserts in vi mode from being undone
|
||||
properly.
|
||||
|
||||
f. Fixed a problem that caused readline to initialize with an incorrect idea
|
||||
of whether or not the terminal can autowrap.
|
||||
|
||||
g. Fixed output of key bindings (like bash `bind -p') to honor the setting of
|
||||
convert-meta and use \e where appropriate.
|
||||
|
||||
h. Changed the default filename completion function to call the filename
|
||||
dequoting function if the directory completion hook isn't set. This means
|
||||
that any directory completion hooks need to dequote the directory name,
|
||||
since application-specific hooks need to know how the word was quoted,
|
||||
even if no other changes are made.
|
||||
|
||||
i. Fixed a bug with creating the prompt for a non-interactive search string
|
||||
when there are non-printing characters in the primary prompt.
|
||||
|
||||
j. Fixed a bug that caused prompts with invisible characters to be redrawn
|
||||
multiple times in a multibyte locale.
|
||||
|
||||
k. Fixed a bug that could cause the key sequence scanning code to return the
|
||||
wrong function.
|
||||
|
||||
l. Fixed a problem with the callback interface that caused it to fail when
|
||||
using multi-character keyboard macros.
|
||||
|
||||
m. Fixed a bug that could cause a core dump when an edited history entry was
|
||||
re-executed under certain conditions.
|
||||
|
||||
n. Fixed a bug that caused readline to reference freed memory when attmpting
|
||||
to display a portion of the prompt.
|
||||
|
||||
3. New Features in Bash
|
||||
|
||||
a. Changed the parameter pattern replacement functions to not anchor the
|
||||
pattern at the beginning of the string if doing global replacement - that
|
||||
combination doesn't make any sense.
|
||||
|
||||
b. When running in `word expansion only' mode (--wordexp option), inhibit
|
||||
process substitution.
|
||||
|
||||
c. Loadable builtins now work on MacOS X 10.[34].
|
||||
|
||||
d. Shells running in posix mode no longer set $HOME, as POSIX requires.
|
||||
|
||||
e. The code that checks for binary files being executed as shell scripts now
|
||||
checks only for NUL rather than any non-printing character.
|
||||
|
||||
f. Quoting the string argument to the [[ command's =~ operator now forces
|
||||
string matching, as with the other pattern-matching operators.
|
||||
|
||||
4. New Features in Readline
|
||||
|
||||
a. Calling applications can now set the keyboard timeout to 0, allowing
|
||||
poll-like behavior.
|
||||
|
||||
b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
|
||||
the default last-ditch startup file.
|
||||
|
||||
c. The history file reading functions now allow windows-like \r\n line
|
||||
terminators.
