+This document details the changes between this version, bash-2.01-release,
+and the previous version, 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. A bug that caused the shell to crash when mixing calls to `getopts'
+ and `shift' on the same set of positional parameters was fixed.
+
+kk. The command printing code now preserves the `-p' flag to `time'.
+
+ll. The command printing code now handles here documents better when there
+ are other redirections associated with the command.
+
+mm. 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.

- 6/29
- ----
-machines.h
- - minor change to the ardent titan machine description
- - move the ardent and stardent descriptions before the
- mips riscos description
+builtins/setattr.def
+ - a bad identifier given to readonly or export without an assignment
+ statement (e.g. `readonly a[5]') is an error, but not an assignment
+ error (i.e., return EXECUTION_FAILURE rather than EX_BADASSIGN)
-print_cmd.c
- - ardent machines also need the extern declaration for printf
+tests/{{array,new-exp}.,tilde-}tests
+ - added `set +o posix' at the beginning to disable POSIX mode, which

+ set POSIXLY_CORRECT by default
-make_cmd.c
- - connect_async_list should do its work only if the lists to be
- backgrounded are connected with `;'. This makes `;' bind tighter

+ - worked around the `noread' and `nowrite' tests failing when run

+lib/readline/{readline,display}.c
+ - a couple of slight changes to build on Win95 using djgpp (reported
+ by x-aes@telelogic.se)
-lib/readline/readline.c
- - provide a function version of savestring, if not being compiled
- into the shell, since the macro has been removed from the
- `public' header files
-
-lib/readline/readline.h
- - provide all extern function declarations without checking whether
- VI_MODE or PAREN_MATCHING are defined. It does not hurt to define
- them if they are not used and not in the library, and other
- applications using readline can't tell whether or not VI_MODE was

- when that one character was at the end of an allocated block
- - changed the ADD_STRING macro to avoid some unnecessary xreallocs
-
-lib/readline/display.c
- - fixed a problem with move_cursor_relative -- function now returns
- immediately if it has nothing to do
- - fixed another problem with displaying prompts with invisible chars
-
-lib/readline/chardefs.h
- - fixed the CTRL macro to be right (agree with the BSD kernel, for
- example)
+ - new function: quote_word_break_characters(), to backslash-quote
+ characters in a filename that the readline completion code would
+ treat as word breaks
+ - change bash_quote_filename to call quote_word_break_characters if
+ the completion quoting style says to use backslashes
+ - add `:' to rl_filename_quote_characters, since it's part of
+ filename_word_break_characters
+
+lib/posixheaders/posixjmp.h

-lib/readline/bind.c
- - in rl_read_init_file, when skipping whitespace at the start of
- the line, decrement `i' so that we don't jump past the start
- of the next line
+trap.c
+ - don't free the trap command for a DEBUG trap in

-machines.h

- - if *qcp is not 0 when passed to bash_quote_filename, adjust the
- type of completion we're doing based on its value (i.e.,
- *qcp == '"' forces double quoting, *qcp == '\'' forces single)
- - bash_quote_filename now leaves the quotes intact in the filename
- it returns. The readline completion code takes care of avoiding
- doubled open quotes
- - if a filename containing a `!' is passed to bash_quote_filename
- without an opening quote character, and we are performing history
- expansion, use single quoting as the quoting style
-
-bashhist.c

- - push_string marks the alias it's passed as being expanded
- (AL_BEINGEXPANDED)
- - pop_string marks the alias being popped as no longer being
- expanded
- - changed shell_getc to defer popping an alias expansion until

-unwind_prot.c
- - changed unwind_protect_var and restore_variable to do the

- used as a prefix character with rl_execute_next
-
-shell.c
- - the GNU coding standards say to write the output generated by

-parse.y

+unwind_prot.c
+ - fixed a problem with saving a variable that is a null pointer

-
-subst.c
- - on systems without /dev/fd, open the named pipe for a `reading

-
-configure.in
- - set up the minimal configuration after checking for

-
- 5/18
- ----
-lib/readline/bind.c
- - fixed _rl_get_keyname() so that it properly handles C-\ and outputs
- it as \C-\\ and C-" as \C-\". This fixes the improper binding
- commands written by `bind -p' that caused weird things to happen
- when people used the output of `bind -p' as a start for their
- own inputrc files
- - new function _rl_init_file_error to print error messages encountered
- while parsing the inputrc file
- - print out an error message if parsing an inputrc line and no closing
- double quote is found for a key binding
-
-lib/readline/complete.c
- - in rl_complete_internal, if the completion function results in
- multiple matches, but none match up to even the first character,
- use what the user typed in (which is presumably a glob pattern
- that expanded into multiple files) as matches[0]. This makes
- things like show-all-if-ambiguous work right, too
-
-oslib.c
- - if we are providing our own version of getenv(), provide a function
- _getenv() as well, which just calls getenv()
-
-builtins/ulimit.def
- - #define _KERNEL before including <sys/resource.h> if HPUX is
- defined. This makes the full set of limits available on hpux
- version 8 and above
+builtins/evalfile.c
+ - if _evalfile() is passed FEVAL_HISTORY as part of the flags arg,
+ don't pass SEVAL_NOHIST to parse_and_execute
+ - new function: fc_execute_file, which sets FEVAL_HISTORY in the
+ flags argument to _evalfile()
bashline.c
- - new function, enable_hostname_completion, sets up readline to
- perform or not perform hostname completion. Hostname completion
- is on by default.
- - don't attempt hostname completion in attempt_shell_completion()
- unless perform_hostname_completion is set
-
-builtins/shopt.def
- - add a `set_func' member to the shopt options structure, to provide
- a hook for those variables that require a little more than just
- toggling a variable on or off
- - new shopt variable `hostcomplete', turns hostname completion on and
- off
-
-doc/{bash.{1,html},features.texi}
- - added description of new shopt `hostcomplete' variable
-

- ----
-sig.c
- - don't try to save the shell history in termination_unwind_protect
- if we're dying due to SIGABRT
+ - call bash_add_history instead of add_history from
+ vi_edit_and_execute_command so the bash state variables get
+ updated properly. This keeps the `v' command from operating
+ on an empty command when the history list is stifled
bashhist.c
- - new functions: last_history_entry (static), last_history_line
+ - bash_add_history is now global
bashhist.h
- - extern declarations for new functions in bashhist.c
-

builtins/fc.def
- - if the editor returns a non-zero exit status when using `fc -e',
- return immediately without trying to execute the commands, as
- per Posix.2, 5.12.2
- - when using `fc -s', echo the command to be executed to stderr,
- not stdout
-
-lib/readline/terminal.c
- - new file, with all code related to termcap/terminfo
-
-lib/readline/{readline,rltty,display,util}.c
- - moved functions dealing with termcap to terminal.c
-
-lib/readline/readline.c
- - readline_initialize_everything now calls _rl_enable_meta_key()
- to turn on the meta key, based on the value of _rl_enable_meta
- (on by default)
-
-lib/readline/rltty.c
- - do not enable and disable the meta key each time readline is
- called; do it once at initialization

-shell.h
- - changed EX_USAGE to 258, EX_BADUSAGE is now 2
- - added a number of execution failure statuses, so that builtins
- can indicate various failures. All are greater than 256, so
- they cannot be returned by other utilities
-
-execute_cmd.c
- - new function, builtin_status(), to translate the new return
- status codes to something the shell can export
- - changed execute_simple_command to call builtin_status after
- execute_builtin_or_function to translate error codes if a
- builtin is invoked. If a function or regular builtin is
- invoked, all return values greater than EX_SHERRBASE get
- translated to EXECUTION_FAILURE, with the exception that
- EX_USAGE gets translated to EX_BADUSAGE. If a special
- builtin failed with a status > EX_SHERRBASE, special_builtin_failed
- is set to cause the shell to exit in POSIX mode
- - changed execute_builtin_or_function to return EX_REDIRFAIL if
- redirections fail
- - changed execute_subshell_builtin_or_function to translate
- EX_USAGE to EX_BADUSAGE if a builtin is executed
- - set this_command_name to NULL in execute_for_command before binding

-
-lib/readline/rldefs.h

-xmalloc.c
- - only do pointer arithmetic on pointers cast to (char *), since
- it's not required that compilers support arithmetic on void *
-
-shell.c
- - make sure <sys/socket.h> is included with the same conditions
- used to call getpeername(2) in isnetconn()
+ - call fc_execute_file instead of maybe_execute_file in the

+ - don't manually insert the commands from the file created by `fc -e'
+ into the history list, just set remember_on_history and let
+ fc_execute_file take care of telling parse_and_execute to do the
+ right thing. This makes compound commands and the `cmdhist'
+ and `lithist' settings work better. This supersedes the fix of
+ 1/27. This was reported again by rchen@fractal.eng.yale.edu.
parse.y
- - added a new function, paren_match, to parse the contents of $(...)
- constructs. This function correctly handles embedded quoted
- strings, embedded command substitutions, embedded command
- substitutions with embedded quoted strings, etc. The implementation
- is much closer to that described in POSIX.2, section 3.6.3.
- - changed read_token_word to call paren_match where appropriate
-
-subst.c
- - rewrote extract_delimited_string so that it correctly understands
- quoted strings inside command substitutions, a la paren_match
- in parse.y. Corrected the description of the function's output
- in the code. extract_delimited_string is now very recursive, and
- does not try to do everything in one pass without recursion

----
-parse.y
- - augmented parse_matched_pair
- o fixed up backslash quoting and CTLESC handling after

- o match pairs of ${...} and $[...] inside double-quoted
- strings or `` strings
- o keep track of line number quoted string starts on for
- better error messages
- o push and pop delimiters when parsing quoted strings
- inside $(...), ${...}, and $[...] for use by the
- history code
- o set EOF_Reached to 1 if we get an EOF before finding the
- match closer
- - rewrote read_token_word from scratch to use parse_matched_pair:
- o shell quote characters use parse_matched_pair to find
- the matching quote
- o fixed up backslash parsing code
- o compound array assignments use parse_matched_pair
- o corrected all_digits and dollar_present computations, so,
- for instance, 2''>/dev/null is no longer accepted as
- identical to 2>/dev/null
- o converted ${...} parsing to use parse_matched_pair
- o removed printing of error messages about unmatched quotes;
- now handled by parse_matched_pair
- o converted $'...' and $"..." to use parse_matched_pair
- o removed all of the delimited_xxx and dollar_xxx variables
- and embedded_quoted_string
- - modified report_syntax_error to regularize error messages:
- o non-interactive shells and interactive shells running
- scripts with `.' now always report line numbers
- o unexpected EOF is always reported when EOF_Reached is true
- o non-interactive shells no longer duplicate the script name
- in error messages (e.g., `./z3: ./z3: line 3: syntax error')

- expansions are now sorted in the per-locale collation order
-
-locale.c
- - track the value of $LC_COLLATE and call setlocale(LC_COLLATE,...)
- when it changes. Also, set its default value
-

- assigned to or unset
-
-lib/readline/util.c

- -----
-variables.c
- - changed the calls to list_string_with_quotes and then

- to ksh93
-
-subst.c
- - commented out list_string_with_quotes -- it is no longer used
-
-lib/readline/terminal.c
- - new function, _rl_set_screen_size(int rows, int cols), to set
- readline's idea of the screen size
-
-jobs.c, nojobs.c

- `checkwinsize' is set with `shopt'
-

- -----
-support/config.guess
- - added code to recognize the various NetBSD ports
-
-lib/readline/signals.c

- quoted environment so it takes spaces in the variable value into
- account
-
- 10/21
- -----
-command.h
- - flags for possible values of subshell_environment telling what
- caused the subshell
-
-builtins/command.def
- - the `command' builtin should not be setting CMD_NO_FORK at all;
- it doesn't know enough about the execution context to do so
-
-execute_cmd.c, subst.c
- - set subshell_environment to one of the values in command.h rather
- than to `1', so we know what kind of subshell it is (just for
- informational purposes; nothing actually uses this yet)

-
-configure.in
- - call BASH_KERNEL_RLIMIT_CHECK if $host_os begins with `hpux'
-
-config.h.in

+This is a terse description of the new features added to bash-2.01 since
+the release of bash-2.0. As always, the manual page (doc/bash.1) is the
+place to look for complete descriptions.
+
+1. 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.
+
+2. 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.

+
+4. I've had reports that username completion (as well as tilde expansion
+ and \u prompt expansion) does not work on IRIX 5.3 when linking with
+ -lnsl. This is only a problem when you're running NIS, since
+ apparently -lnsl supports only /etc/passwd and not the NIS functions
+ for retrieving usernames and passwords. Editing the Makefile after
+ configure runs and removing the `-lnsl' from the assignment to `LIBS'
+ fixes the problem.
+
+5. 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. It will make your system
+ vulnerable to bogus system(3) calls in setuid executables.
