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. + +------------------------------------------------------------------------------ This document details the changes between this version, bash-3.1-release, and the previous version, bash-3.1-rc2. @@ -48,7 +306,7 @@ and the previous version, bash-3.1-beta1. 1.
