bash-2.01-beta2. + +1. Changes to Bash + +a. The `distclean' target should remove the `printenv' executable if it + has been created. + +b. The test suite was changed slightly to ensure that the error messages + are printed in English. + +c. A bug that caused the shell to dump core when a filename containing a + `/' was passed to `hash' was fixed. + +d. Pathname canonicalization now leaves a leading `//' intact, as POSIX.1 + requires. + +e. A memory leak when completing commands was fixed. + +f. A memory leak that occurred when checking the hash table for commands + with relative paths was fixed. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.01-beta2, +and the previous version, bash-2.01-beta1. + +1. Changes to Bash + +a. The `ulimit' builtin translates RLIM_INFINITY to the hard limit only if + the current (soft) limit is less than or equal to the hard limit. + +b. Fixed a bug that caused the bash emulation of strcasecmp to produce + incorrect results. + +c. A bug that caused memory to be freed twice when a trap handler resets + the trap more than once was fixed. + +d. A bug that caused machines where sizeof (pointer) > sizeof (int) to + fail (and possibly dump core) when trying to unwind-protect a null + pointer was fixed. + +e. The startup files should not be run with job control enabled. This fix + allows SIGINT to once again interrupt startup file execution. + +f. Bash should not change the SIGPROF handler if it is set to something + other than SIG_DFL. + +g. The completion code that provides bash-specific completions for readline + now quotes characters that the readline code would treat as word break + characters if they appear in a file name. + +h. The completion code now correctly quotes filenames containing a `!', + even if the user attempted to use double quotes when attempting + completion. + +i. A bug that caused the shell to dump core when `disown' was called without + arguments and there was no current job was fixed. + +j. A construct like $((foo);bar) is now processed as a command substitution + rather than as a bad arithmetic substitution. + +k. A couple of bugs that caused `fc' to not obey the `cmdhist' and `lithist' + shell options when editing and re-executing a series of commands were + fixed. + +l. A fix was made to the grammar -- the list of commands between `do' and + `done' in the body of a `for' command should be treated the same as a + while loop. + +2. Changes to Readline + +a. A couple of bugs that caused the history search functions to attempt to + free a NULL pointer were fixed. + +b. If the C library provides setlocale(3), readline does not need to look + at various environment variables to decide whether or not to go into + eight-bit mode automatically -- just check whether the current locale + is not `C' or `POSIX'. + +c. If the filename completion function finds that a directory was not closed + by a previous (interrupted) completion, it closes the directory with + closedir(). + +3. New Features in Bash + +a. New bindable readline commands: history-and-alias-expand-line and + alias-expand-line. The code was always in there, there was just no + way to execute it. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.01-beta1, +and the previous version, bash-2.01-alpha1. + +1. Changes to Bash + +a. Fixed a problem that could cause file descriptors used for process + substitution to conflict with those used explicitly in redirections. + +b. Made it easier to regenerate configure if the user changes configure.in. + +c. ${GROUPS[0]} should always be the primary group, even on systems without + multiple groups. + +d. Spelling correction is no longer enabled by default. + +e. Fixes to quoting problems in `bashbug'. + +f. OS-specific configuration changes were made for: Irix 6. + +g. OS-specific code changes were made for: QNX. + +h. A more meaningful message is now printed when the file in /tmp for a + here document cannot be created. + +i. Many changes to the shell's variable initialization code to speed + non-interactive startup. + +j. Changes to the non-job-control code so that it does not try to open + /dev/tty. + +k. The output of `set' and `export' is once again sorted, as POSIX wants. + +l. Fixed a problem caused by a recursive call reparsing the value of + $SHELLOPTS. + +m. The tilde code no longer calls getenv() when it's compiled as part of + the shell, which should eliminate problems on systems that cannot + redefine getenv(), like the NeXT OS. + +n. Fixed a problem that caused `bash -o' or `bash +o' to not list all + the shell options. + +o. Fixed `ulimit' to convert RLIM_INFINITY to the appropriate hard limit + only if the hard limit is greater than the current (soft) limit. + +p. Fixed a problem that arose when building bash in a different directory + than the source and y.tab.[ch] were remade with something other than + bison. This came up most often on NetBSD. + +q. Fixed a problem with completion -- it thought that `pwd`/[TAB] indicated + an unfinished command completion (`/), which generated errors. + +r. The bash special tilde expansions (~-, ~+) are now attempted before + calling the standard tilde expansion code, which should eliminate the + problems people have been seeing with this on Solaris 2.5.1. + +s. Added support for <stdarg.h> to places where it was missing. + +t. Changed the code that reads the output of a command substitution to not + go through stdio. This reduces the memory requirements and is faster. + +u. A number of changes to speed up export environment creation were made. + +v. A number of memory leaks were fixed as the result of running the test + scripts through Purify. + +w. Fixed a bug that caused subshells forked to interpret executable + scripts without a leading `#!' to not reinitialize the values of + the shell options. + +2. Changes to Readline + +a. History library has less `#ifdef SHELL' code -- abstracted stuff out + into application-specific function hooks. + +b. Readline no longer calls getenv() if it's compiled as part of the shell, + which should eliminate problems on systems that cannot redefine getenv(), + like the NeXT OS. + +c. Fixed translation of ESC when `untranslating' macro values. + +d. The region kill operation now fixes the mark if it ends up beyond the + boundaries of the line after the region is deleted. + +3. New Features in Bash + +a. New argument for `configure': `--with-curses'. This can be used to + override the selection of the termcap library on systems where it is + deficient. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.01-alpha1, +and the previous version, bash-2.0-release. + +1. Changes to Bash + +a. System-specific configuration changes for: FreeBSD, SunOS4, Irix, + MachTen, QNX 4.2, Harris Night Hawk, SunOS5. + +b. System-specific code changes were made for: Linux, 4.4 BSD, QNX 4.2, + HP-UX, AIX 4.2. + +c. A bug that caused the exec builtin to fail because the full pathname of + the command could not be found was fixed. + +d. The code that performs output redirections is now more resistant to + race conditions and possible security exploits. + +e. A bug that caused the shell to dump core when performing pattern + substitutions on variable values was fixed. + +f. More hosts are now recognized by the auto-configuration mechanism + (OpenBSD, QNX, others). + +g. Assignments to read-only variables that attempt to convert them to + arrays are now errors. + +h. A bug that caused shell scripts using array assignments in POSIX mode + to exit after the assignment was performed was fixed. + +i. The substring expansion code is now more careful about running off the + ends of the expanded variable value. + +j. A bug that caused completion to fail if a backquoted command substitution + appeared anywhere on the line was fixed. + +k. The `source' builtin no longer turns off history if it has been enabled + in a non-interactive shell. + +l. A bug that caused the shell to crash when `disown' was given a pid + instead of a job number was fixed. + +m. The `cd' spelling correction code will not try to change to `.' if no + directory entries match a single-character argument. + +n. A bad variable name supplied to `declare', `export', or `readonly' no + longer causes a non-interactive shell in POSIX mode to exit. + +o. Some fixes were made to the test suite to handle peculiarities of + various Unix versions. + +p. The bash completion code now quotes characters that readline would + treat as word breaks for completion but are not shell metacharacters. + +q. Bad options supplied at invocation now cause a usage message to be + displayed. + +r. Fixes were made to the code that handles DEBUG traps so that the trap + string is not freed inappropriately. + +s. Some changes were made to the bash debugger in examples/bashdb -- it + should be closer to working now. + +t. A problem that caused the default filename used for mail checking to be + wrong was fixed. + +u. A fix was made to the `echo' builtin so that NUL characters printed with + `echo -e' do not cause the output to be truncated. + +v. A fix was made to the job control code so that the shell behaves better + when monitor mode is enabled in a non-interactive shell. + +w. Bash no longer catches all of the terminating signals in a non- + interactive shell until a trap is set on EXIT, which should result in + quicker startup. + +x. A fix was made to the command timing code so that `time' can be used in + a loop. + +y. A fix was made to the parser so that `((cmd); cmd2)' is now parsed as + a nested subshell rather than strictly as an (errnoeous) arithmetic + command. + +z. A fix was made to the globbing code so that it correctly matches quoted + filenames beginning with a `.'. + +aa. A bug in `fc' that caused some multi-line commands to not be stored as + one command in the history when they were re-executed after editing + (with `fc -e') was fixed. + +bb. The `ulimit' builtin now attempts to catch some classes of integer + overflows. + +cc. The command-oriented-history code no longer attempts to add `;' + inappropriately when a newline appears while reading a $(...) command + substitution. + +dd. A bug that caused the shell to dump core when `help --' was executed + was fixed. + +ee. A bug that caused the shell to crash when an unset variable appeared + in the body of a here document after `set -u' had been executed was + fixed. + +ff. Implicit input redirections from /dev/null for asynchronous commands + are now handled better. + +gg. A bug that caused the shell to fail to compile when configured with + `--disable-readline' was fixed. + +hh. The globbing code should now be interruptible. + +ii. Bash now notices when the `kill' builtin is used to send SIGCONT to a + stopped job and adjusts the data structures accordingly, as if `bg' had + been executed instead. + +jj.

The special glibc environment variable (NNN_GNU_nonoption_argv_flags_) + is no longer placed into the environment of executed commands -- users + of glibc had too many problems with it. + +nn. Reorganized the code that generates signames.h. The signal_names list + is now more complete but may be slightly different (SIGABRT is favored + over SIGIOT, for example). The preferred signal names are those + listed in the POSIX.2 standard. + +oo. `bashbug' now uses a filename shorter than 14 characters for its + temporary file, and asks for confirmation before sending the bug + report. + +pp. A bug that caused TAB completion in vi editing mode to not be turned + off when `set -o posix' was executed or back on when `set +o posix' + was executed was fixed. + +qq. A bug in the brace expansion code that caused brace expansions appearing + in new-style $(...) command substitutions to be inappropriately expanded + was fixed. + +rr. A bug in the readline hook shell-expand-line that could cause memory to + be inappropriately freed was fixed. + +ss. A bug that caused some arithmetic expressions containing `&&' and `||' + to be parsed with the wrong precedence has been fixed. + +tt. References to unbound variables after `set -u' has been executed now + cause the shell to exit immediately, as they should. + +uu. A bug that caused the shell to exit inappropriately when `set -e' had + been executed and a command's return status was being inverted with the + `!' reserved word was fixed. + +vv. A bug that could occasionally cause the shell to crash with a + divide-by-zero error when timing a command was fixed. + +ww. A bug that caused parameter pattern substitution to leave stray + backslashes in the replacement string when the expression is in + double quotes was fixed. + +xx. The `break' and `continue' builtins now break out of all loops when an + invalid count argument is supplied. + +yy. Fixed a bug that caused PATH to be set to the empty string if + `command -p' is executed with PATH unset. + +zz. Fixed `kill -l signum' to print the signal name without the `SIG' prefix, + as POSIX specifies. + +aaa. Fixed a bug that caused the shell to crash while setting $SHELLOPTS + if there were no shell options set. + +bbb. Fixed `export -p' and `readonly -p' so that when the shell is in POSIX + mode, their output is as POSIX.2 specifies. + +ccc. Fixed a bug in `readonly' so that `readonly -a avar=(...)' actually + creates an array variable. + +ddd. Fixed a bug that prevented `time' from correctly timing background + pipelines. + +2. Changes to Readline + +a. A bug that caused an extra newline to be printed when the cursor was on + an otherwise empty line was fixed. + +b. An instance of memory being used after it was freed was corrected. + +c. The redisplay code now works when the prompt is longer than the screen + width. + +d. `dump-macros' is now a bindable name, as it should have been all along. + +e. Non-printable characters are now expanded when displaying macros and + their values. + +f. The `dump-variables' and `dump-macros' commands now output a leading + newline if they're called as the result of a key sequence, rather + than directly by an application. + +3. New Features in Bash + +a. There is a new builtin array variable: GROUPS, the set of groups to which + the user belongs. This is used by the test suite. + +4. New Features in Readline + +a. If a key sequence bound to `universal-argument' is read while reading a + numeric argument started with `universal-argument', it terminates the + argument but is otherwise ignored. This provides a way to insert multiple + instances of a digit string, and is how GNU emacs does it. + +------------------------------------------------------------------------------ This document details the changes between this version, bash-2.0-release, and the previous version, bash-2.0-beta3. @@ -1,7 +1,7 @@ This document details the incompatibilites between this version of bash, -bash-2.0, and the previous version, bash-1.14.

There is a problem with Red Hat Linux's `makewhatis' script. + Running `makewhatis' with bash-2.0 results in error messages + like this: + + /usr/sbin/makewhatis: cd: manpath: No such file or directory + /usr/sbin/makewhatis: manpath/whatis: No such file or directory + chmod: manpath/whatis: No such file or directory + /usr/sbin/makewhatis: cd: catpath: No such file or directory + /usr/sbin/makewhatis: catpath/whatis: No such file or directory + chmod: catpath/whatis: No such file or directory + + The problem is with `makewhatis'. Red Hat (and possibly other + Linux distributors) uses a construct like this in the code: + + eval path=$"$pages"path + + to do indirect variable expansion. This `happened to work' in + bash-1.14 and previous versions, but that was more an accident + of implementation than anything else -- it was never supported + and certainly is not portable. + + Bash-2.0 has a new feature that gives a new meaning to $"...". + This is explained more completely in item 1 in the COMPAT file. + + The three lines in the `makewhatis' script that need to be changed + look like this: + + eval $topath=$"$topath":$name + [...] + eval path=$"$pages"path + [...] + eval path=$"$pages"path + + The portable way to write this code is + + eval $topath="\$$topath":$name + eval path="\$$pages"path + eval path="\$$pages"path + + You could also experiment with another new bash feature: ${!var}. + This does indirect variable expansion, making the use of eval + unnecessary. + +6. There is a problem with syslogd on many Linux distributions (Red Hat + and Slackware are two that I have received reports about). syslogd + sends a SIGINT to its parent process, which is waiting for the daemon + to finish its initialization. The parent process then dies due to + the SIGINT, and bash reports it, causing unexpected console output + while the system is booting that looks something like + + starting daemons: syslogd/etc/rc.d/rc.M: line 29: 38 Interrupt ${NET}/syslogd + + Bash-2.0 reports events such as processes dying in scripts due to + signals when the standard output is a tty. Bash-1.14.x and previous + versions did not report such events. + + This should probably be reported as a bug to whatever Linux distributor + people see the problem on. In my opinion, syslogd should be changed to + use some other method of communication, or the wrapper function (which + appeared to be `daemon' when I looked at it some time ago) or script + (which appeared to be `syslog') should catch SIGINT, since it's an + expected event, and exit cleanly. + +7. Several people have reported that `dip' (a program for SLIP/PPP + on Linux) does not work with bash-2.0 installed as /bin/sh. + + I don't run any Linux boxes myself, and do not have the dip + code handy to look at, but the `problem' with bash-2.0, as + it has been related to me, is that bash requires the `-p' + option to be supplied at invocation if it is to run setuid + or setgid. + + This means, among other things, that setuid or setgid programs + which call system(3) (a horrendously bad practice in any case) + relinquish their setuid/setgid status in the child that's forked + to execute /bin/sh. + + The following is an *unofficial* patch to bash-2.0 that causes it + to not require `-p' to run setuid or setgid if invoked as `sh'. + It has been reported to work on Linux.
