+[bash-2.05 released]
+
+ 4/10
+ ----
+redir.c
+ - check return value of fclose() in write_here_document() for error
+ returns; don't just rely on fwrite() failing
+
+support/bashbug.sh
+ - set TMPDIR to /tmp if it's null or unset
+ - use $TMPDIR in the TEMP tempfile name template
+ - fixed the call to `mktemp', if it exists, to make it more portable
+
+jobs.c
+ - if WCONTINUED is not defined, define it to 0 and add a define for
+ WIFCONTINUED(wstatus) which expands to 0
+ - add WCONTINUED to the flags passed to waitpid(2) in waitchld()
+ - don't increment children_exited if waitpid's status is WIFCONTINUED,
+ since we don't want to call a SIGCHLD trap handler in this case
+ - in waitchld(), we set child->running to 1 if WIFCONTINUED(status)
+ is non-zero
+ - make sure pretty_print_job doesn't check for the core dump bit if
+ the process has been continued; it's only valid if the job is dead
+ - in set_job_status_and_cleanup, set the job to JRUNNING if job_state
+ is non-zero and the job was previously marked as JSTOPPED
+
+configure.in
+ - add -DBROKEN_DIRENT_D_INO to interix LOCAL_CFLAGS
+
+lib/glob/glob.c
+ - if BROKEN_DIRENT_D_INO is defined, define REAL_DIR_ENTRY to 1
+
+jobs.c
+ - in kill_pid, we only need to block and unblock SIGCHLD if the
+ `group' argument is non-zero, since otherwise we just call `kill'
+ on the pid argument
+
+version.c
+ - update copyright date to 2001
+
+bashline.c
+ - prog_complete_return needs to take a `const char *' as its first
+ argument
+ - history_completion_generator needs to take a `const char *' as
+ its first argument, and `text' needs to be a `const char *'
+
+ 4/11
+ ----
+redir.c
+ - fixed a weird typo in redir_special_open, case RF_DEVFD, added
+ call to all_digits before call to legal_number
+ - fixed do_redirection_internal to call legal_number instead of atol(3)
+ when translating r_duplicating_{in,out}put_word, so it handles
+ overflow better
+ - produce an error message in redirection_error for out-of-range
+ file descriptors
+ - change allocation strategy in redirection_error so we don't have to
+ malloc scratch memory if redirection_expand() fails
+
+jobs.h
+ - added defines for `running' member of a struct process
+
+general.c
+ - fix legal_number to return 0 when strtol(3) reports overflow or
+ underflow

+ - fixed bogus comment about IS_DESCRIPTOR in description of the
+ REDIRECTEE struct
+
+print_cmd.c
+ - change cprintf's 'd' modifier code to display negative numbers as
+ an out-of-range value. We can do this only because the only use
+ of %d is to output file descriptor numbers in redirections
+
+support/mksignames.c
+ - need to include config.h to get a possible value for
+ UNUSABLE_RT_SIGNALS
+
+ 4/16
+ ----

+ - need to initialize `ind' before calls to RESIZE_MALLOCED_BUFFER
+ in strcreplace()
+
+support/bashversion.c
+ - new file, prints bash version information
+
+Makefile.in
+ - rules for building bashversion and linking it to version.o
+
+ 4/24
+ ----
+conftypes.h
+ - new file with HOSTTYPE, OSTYPE, MACHTYPE, etc. defines from
+ variables.h
+
+variables.h, version.c
+ - include conftypes.h
+
+patchlevel.h
+ - new file, contains define for PATCHLEVEL. Doing away with the old
+ scheme of having the information in configure.in
+
+version.c
+ - include patchlevel.h
+
+Makefile.in
+ - run bashversion -p to find patch level rather than have configure
+ substitute in a value
+ - pass -S ${top_srcdir} to support/mkversion.sh
+
+support/mkversion.sh
+ - don't put PATCHLEVEL define into version.h, but accept and ignore
+ a -p option
+ - take a new -S srcdir option
+ - find the patch level by parsing it out of patchlevel.h
+
+configure.in
+ - hard-code BASHVERS assignment instead of reading it from a file
+ - remove BASHPATCH; don't substitute it
+
+_distribution,_patchlevel
+ - removed
+
+ 4/26
+ ----
+shell.c
+ - call init_noninteractive() in open_shell_script if forced_interactive
+ is non-zero (the shell was started with -i) and fd_is_tty is 0
+ (the script file is a real file, not something like /dev/stdin),
+ since it wasn't done earlier
+
+builtins/printf.def
+ - change for POSIX.2 compliance when conversion errors are encountered
+ when processing %d, %u, and floating point conversion operators
+ (print a warning message, return the value accumulated at the time
+ of the error -- which is always 0 -- and exit with a non-zero status)
+
+command.h
+ - added CMD_COMMAND_BUILTIN for use by the `command' builtin and the
+ code in execute_cmd.c
+
+builtins/command.def

+
+lib/readline/doc/rltech.texinfo
+ - documented rl_get_termcap
+ - documented rl_readline_version
+
+jobs.c
+ - job_exit_status should return an int, not a WAIT (undetected
+ before because on most POSIX-like systems a WAIT is really an int)
+
+builtins/evalfile.c
+ - added FEVAL_REGFILE (file must be a regular file) to accepted
+ _evalfile flags
+ - fc_execute_file() adds FEVAL_REGFILE to _evalfile flags. This
+ means that startup files and files read with `.' no longer need
+ to be regular files
+
+ 5/2
+ ---
+
+lib/termcap/Makefile.in
+ - fix target for installed termcap library (normally unused)
+
+lib/tilde/Makefile.in

+ field width with left-justification
+ - fix to mklong to avoid static buffers, which can always be overrun
+ by someone sufficiently motivated

+ - change var in add_host_name to type `size_t' for passing to xrealloc
+
+ 5/3
+ ---

+ may not fit into a pointer, change call
+
+unwind_prot.c
+ - use a union UWP in restore_variable when restoring a variable whose
+ size is the same as sizeof(int), the reverse of the method used to
+ store it in unwind_protect_int
+
+builtins/printf.def
+ - use a #define LENMODS containing the length modifiers instead of
+ testing against each possible modifier character, save any mod
+ character found
+ - add support for ISO C99 length specifiers `j', `t', and `z'
+ - if `L' modifier is supplied with a floating point conversion char,
+ pass a `long double' to printf if HAVE_LONG_DOUBLE is defined

+ - check for integer overflow of arguments to `-t'
+
+lib/sh/netopen.c
+ - change _getserv() to reject negative port/service numbers
+
+expr.c

+ - use INT_STRLEN_BOUND instead of static array sizes when converting
+ various strings to integer values
+
+shell.h
+ - struct fd_bitmap now uses an `int' size, since it's bounded by

+
+execute_cmd.c
+ - FD_BITMAP_DEFAULT_SIZE is now 32, not 32L
+ - new_fd_bitmap takes an `int' size parameter, not a `long'
+
+execute_cmd.h
+ - change prototype for new_fd_bitmap()

+ BASH_CHECK_LIB_TERMCAP
+ - new macro, RL_LIB_READLINE_VERSION, checks version of installed

+
+configure.in
+ - call RL_LIB_READLINE_VERSION instead of support/rlvers.sh
+
+execute_cmd.c
+ - fix execute_shell_script and the WHITECHAR and STRINGCHAR macros

+ - consolidate tests for valid history position in one block to
+ avoid duplicate code and strings
+
+builtins/ulimit.def
+ - fix check for overflow when setting limit to work when int is 32

+ since it's being assigned to an `unsigned long'
+
+mailcheck.c
+ - use legal_number instead of atoi in time_to_check_mail() to catch
+ more numeric errors; consolidate error checking in one block
+ - last_time_mail_checked should be a time_t

+ - if --with-installed-readline=PREFIX is supplied, set ac_cv_rl_prefix
+ to PREFIX before calling RL_LIB_READLINE_VERSION
+ - if --with-installed-readline[=PREFIX] is supplied, don't set

+
+shell.c
+ - changed isnetconn() to check SSH_CLIENT and SSH2_CLIENT only if

+pcomplete.c
+ - fix gen_matches_from_itemlist to return if the stringlist is null
+ after any cleaning or initialization, before trying to use it
+ - fix GEN_COMPS to only bother to try to append the STRINGLIST
+ returned by gen_matches_from_itemlist to `glist' if it's non-NULL
+
+lib/sh/stringlist.c
+ - make copy_stringlist return NULL if the STRINGLIST * passed as an

+ - make append_stringlist call copy_stringlist only if M2 is non-NULL;
+ otherwise just return NULL if m1 is NULL
+ - make word_list_to_stringlist return 0 immediately if the passed
+ LIST argument is NULL
+ - make realloc_stringlist call alloc_stringlist if the passed
+ STRINGLIST argument (`sl') is 0, just like realloc calls malloc
+
+subst.c
+ - in skip_to_delim(), if we have an unclosed ${, and it's at the end
+ of the string (string[i] == '{', string[i+1] == '{' and
+ string[i+2] == 0, return si (i +2) immediately without bothering
+ to call extract_dollar_brace_string or extract_delimited_string
+ - in skip_to_delim(), if string[i] is 0 after a call to
+ extract_dollar_brace_string or extract_delimited_string (meaning we
+ have an unclosed ${ or other expansion, return i immediately without
+ doing a `continue' (which will increment i past the end of string)
+ - in split_at_delims, don't increment te by 1 if it's pointing to a
+ delimiter. this has the effect of skipping the first delimiter
+ char in a possibly multi-character delimiter, and ignoring
+ single-char delimiters like `>'
+
+configure.in
+ - use AC_CHECK_MEMBERS([struct stat.st_blocks]) instead of a call to
+ AC_STRUCT_ST_BLOCKS to avoid configure changing LIBOBJS if the test
+ fails
+
+general.c
+ - introduce two new variables: bash_tilde_{prefixes,suffixes}, set
+ to the additional prefixes and suffixes bash wants to pass to the
+ tilde expansion code (reserved for post-bash-2.05a fix)
+
+aclocal.m4
+ - add missing `test' in BASH_CHECK_SYS_SIGLIST
+
+ 11/7
+ ----
+lib/readline/vi_mode.c
+ - fix rl_vi_goto_mark to explicitly check that the desired mark is
+ between 'a' and 'z', since some locales have lowercase letters
+ outside that range, which could cause a negative subscript
+
+include/chartypes.h
+ - remove superfluous `#undef ISASCII'
+
+lib/sh/strto[iu]max.c
+ - changes from Paul Eggert to work around buggy compilers and catch
+ configuration errors at compile time
+
+aclocal.m4
+ - new macro, BASH_C_LONG_DOUBLE, identical to AC_C_LONG_DOUBLE but
+ with a fix for Irix 5.3 (not called, since I'm not sure it's the
+ right thing to do -- the C standard allows double and long double
+ to be the same size)
+
+lib/sh/snprintf.c
+ - only try to write the trailing NUL in vsnprintf_internal if

+ - changed RELSTATUS to `release'
+
+ 11/8

+{arrayfunc,variables}.c
+ - changed calling sequence for dynamic array variable `assign'
+ functions to (SHELL_VAR *self, char *value, arrayind_t ind)
+ - changed calling sequence for dynamic variable assign functions
+ to the same as array variable assign_func. Now this can be
+ prototyped
+
+variables.h
+ - the assign_func member of a `struct variable' is now of type
+ `sh_var_assign_func_t', which is prototyped
+ - the dynamic_value member of a `struct variable' is now of type
+ `sh_var_value_func_t', which is prototyped
+
+variables.c

+
+builtins/cd.def
+ - when in posix mode, if the new directory name formed by PWD and

+ - if canonicalization failed, but the fallback to the directory
+ name specified by the user succeeds, reset the current working
+ directory
+
+lib/readline/{input.c,rlprivate.h}
+ - renamed rl_unget_char to _rl_unget_char; made library global
+
+lib/readline/{{bind,readline}.c,{keymaps,rlprivate}.h}
+ - support for `key subsequences'; allows a key sequence and a function
+ mapped to a subsequence of that key sequence. Primarily to allow
+ arrow keys to be bound in readline vi insert mode, while preserving
+ the ESC function to switch to command mode.
+
+lib/readline/{input.c,rlprivate.h}
+ - new function, _rl_input_queued(T), does a check with select or
+ FIONREAD with a timeout of `T' (which is generally 0)
+
+lib/readline/readline.c
+ - change _rl_dispatch_subseq to test for input in the queue if we
+ get ESC while in vi insertion mode if the keymap entry type for
+ ESC is ISKMAP. If _rl_input_queued returns non-zero, we assume
+ that an arrow key sequence has been pressed and go ahead with the
+ subsequence. If it returns zero, we assume that the user pressed
+ ESC to switch into command mode, and dispatch to that right away.
+ This avoids forcing the user to press another key before switching
+ into command mode
+
+ 11/21
+ -----
+lib/readline/readline.c
+ - bind common arrow key sequences in vi insertion keymap
+
+lib/readline/terminal.c
+ - bind termcap definition's arrow keys in vi insertion keymap
+
+lib/readline/bind.c
+ - check for rl_vi_movement_mode in _rl_bind_if_unbound, so
+ binding the arrow keys can work
+
+lib/readline/readline.c
+ - since _rl_bind_if_unbound does the check of what's currently
+ bound to the key sequence, the check in bind_arrow_keys_internal
+ was redundant
+ - bind_arrow_keys_internal now takes a Keymap argument and handles
+ saving and restoring _rl_keymap; changed bind_arrow_keys
+ accordingly
+
+builtins/fc.def
+ - fix from Paul Eggert to substitute the nearest history number in
+ range if an out-of-range value is supplied. POSIX requires this
+
+lib/sh/pathcanon.c
+ - fix from Corrina Vinschen for the special `cygdrive' prefix on
+ Cygwin
+
+bashhist.c
+ - split the history adding code into more pieces:
+ check_history_control (char *line) checks LINE against the value
+ of HISTCONTROL, returning 1 if LINE should be saved and 0 if not
+
+ check_add_history (char *line) calls check_history_control and
+ history_should_ignore (line) and saves the line with
+ bash_add_history if the checks indicate that it should be saved
+
+ maybe_add_history just calls check_add_history to set the value
+ of first_line_saved
+
+bashhist.h
+ - extern declaration for check_add_history()
+
+shell.c
+ - don't call load_history() from the interactive shell startup
+ code if history_lines_this_session is > 0, indicating that we've
+ already saved some lines in the history and that we probably
+ don't want to overwrite them
+
+builtins/history.def
+ - call check_add_history from push_history, so `history -s xx'
+ works even when in a compound command whose first line has not
+ been saved. (Caveat: in a compound command when the first
+ line has been saved, the line supplied to history -s will become
+ part of the compound command's history entry. Of course, the
+ delete_history call could remove the compound command from the
+ history entirely)
+
+bashline.c
+ - use sh_makepath instead of xmalloc/sprintf in
+ command_word_completion_function
+
+lib/readline/complete.c
+ - get_y_or_n now takes an int FOR_PAGER argument; caller changed
+ If FOR_PAGER is non-zero, get_y_or_n returns appropriate values
+ for a more-like pager: `newline' or `return' return 2; `q' or
+ `Q' return 0
+ - there is now a mini internal more-like pager for displaying a
+ list of completions that exceeds the screen height (new function
+ _rl_internal_pager, called from rl_display_match_list)

+
+bashline.c
+ - fix attempt_shell_completion to turn off

+
+ 11/26
+ -----
+lib/readline/rltech.texinfo
+ - a couple of additions to the rl_stuff_char description
+
+parse.y
+ - turn off echo_input_at_read in parse_string_to_word_list, so `set -v'
+ doesn't give extra lines of output when doing compound array

+
+subst.c
+ - fix split_at_delims to handle skipping over a `\n' if it's a

+ - new extern declaration for find_token_in_alist()
+
+subst.c
+ - string_list_internal is no longer static
+
+subst.h
+ - new extern declaration for string_list_internal()
+
+parse.y
+ - new alist array of other tokens returned by read_token which are
+ not reserved words in word_token_alist[]
+ - reworked error reporting: new functions print_offending_line,
+ which prints the line containing the syntax error,
+ error_token_from_token, which takes the current token and tries to
+ figure out its textual representation, and error_token_from_text,
+ which does the old job of finding the bad token by analyzing the
+ text of shell_input_line at the current index
+ - report_syntax_error now tries to figure out the token that caused
+ the syntax error by first looking at current_token and falling
+ back to the old method of textual analysis if that fails
+ - report_syntax_error doesn't say the token resulting from the textual
+ analysis of the input line is an `unexpected token'; it just
+ says there is a `syntax error near xxx'
+ - changed conditional command error reporting to use the value
+ returned by error_token_from_token if it's not null instead of
+ just using the token value in the message, since current_token
+ ends up being set to -1, and the text of the message from
+ report_syntax_error might not be exactly right
+ - change parse_string_to_word_list to set current_token to the
+ offending token returned by read_token before calling yyerror()
+ to make the error reporting do the right thing
+
+aclocal.m4
+ - fixed typo in BASH_CHECK_LIB_TERMCAP
+

+ 0 with non-zero length
+
+builtins/read.def
+ - TMOUT is now the default timeout for `read' (and select) if set,
+ like ksh93 when reading from the terminal
+ - edit_line (called by read -e) now just does readline's filename
+ completion by setting rl_attempted_completion_function to NULL,
+ since e.g., doing command completion for the first word on the
+ line wasn't really useful
+
+execute_cmd.c
+ - changed select_command to return failure status if select_query
+ returns NULL, indicating that read_builtin returned
+ EXECUTION_FAILURE
+
+doc/{bash.1,bashref.texi}
+ - documented new TMOUT behavior
+ - slight change to the description of the test `-ef' option
+
+doc/bashref.texi

+ - break the code that actually calls add_history out of

+ (force != 0)
+
+builtins/history.def
+ - in push_history, call delete_last_history if the current command
+ has more than one line, the first line was saved, and
+ command-oriented history is active. This takes care of deleting
+ the right history element if `history -s' is used within a

+ - in push_history, call check_add_history with second argument of 1

+
+variables.c, jobs.c
+ - changed set_pipestatus_array callers

+
+jobs.c
+ - new function, compact_jobs_list, removes some number of jobs from

+ now sets rl_mark to 0
+ - rl_get_{next,previous}_history set rl_mark to 0 if rl_point is at

+lib/readline/complete.c
+ - slight change to mark-directories code to avoid adding a slash if
+ point is at the end of the line (rl_line_buffer[rl_point] == '\0')
+ and the previous character was a slash
+ - change printable_part to not return empty pathnames, which could
+ happen when completing filenames and a filename with a trailing
+ slash was passed as the argument. If the portion following the
+ trailing slash is NULL, ignore it and look for a previous slash.
+ If there's no previous slash, just return the filename argument
+ - new variable, rl_completion_mark_symlink_dirs, mirrors the value
+ of (user-settable with a variable) _rl_complete_mark_symlink_dirs

+ when appropriate (set in rl_complete_internal and rl_menu_complete)
+
+lib/readline/readline.h
+ - extern declaration for rl_completion_mark_symlink_dirs

+ imposed by a restricted shell
+
+expr.c
+ - broke the code that evaluates variables and returns results out
+ of readtok() into a new function: expr_streval()
+ - expr_streval() now performs the standard unset variable error
+ behavior if `set -u' has been executed and it's asked to look
+ up an unset variable
+ - broke the code that frees up the expression context stack into
+ a new function: expr_unwind()
+
+variables.c
+ - fixed bind_int_variable so it handles array element assignment,
+ so expressions like `b[7]++' and `b[0] = 42' work right
+ - new function, get_variable_value, returns the string value of

+parse.y
+ - replace code in decode_prompt_string that chops up value returned

+ of \@ has changed slightly (since it depends on the locale)
+ - added new \D{format} prompt string escape; `format' is passed to

+ ----
+variables.h, execute_cmd.c
+ - declare variables describing the temporary environments in

+ - broke the body of make_var_array out into a new function:

+ - change make_local_variable to set the initial value of the

+ - changed calls to find_pipeline and find_job made from waitchld
+ to find only running processes
+ - find_pipeline takes a third argument: an int *. If it looks in

+jobs.c
+ - renamed old `waiting_for_job' variable to `queue_sigchld', which
+ better reflects its intent: sigchld_handler does not call waitchld
+ if `queue_sigchld' is non-zero, it simply increments the count of
+ waiting children

+ - in setjstatus, only call xrealloc if `statsize' is less than the
+ number of processes passed -- no reason to do it if they're the

+ - moved code from parameter_brace_expand into a new function that
+ dispatches for pattern substitution: parameter_brace_remove_pattern
+ - changed structure of parameter_brace_remove_pattern to be like
+ parameter_brace_patsub and its ilk: call get_var_and_type to
+ isolate the variable name, move the pattern isolation code out of
+ the various *_remove_pattern functions into
+ parameter_brace_remove_pattern and pass the results to the various
+ functions, use a switch on the return value from get_var_and_type
+ to decide which function to call, regularized the arguments to the
+ separate pattern removal functions
+ - parameter_brace_remove_pattern now properly quotes escape chars in
+ the returned value
+ - changed get_var_and_type to call dequote_escapes on the `value'
+ parameter for case VT_VARIABLE and return the result in *valp,
+ so the calling functions don't have to do it themselves; changed
+ callers appropriately
+ - fixed getpattern() where it broke posix compliance: if you enclose

+ have no effect on the pattern (POSIX.1-200x 2.6.2). This uncovered
+ a bug in the test suite (!)

+ o begin and end range guards are now the same value: the chunk

+ o coalescing code was changed to attempt to coalesce first two

+ o blocks of size 32 are now candidates for larger block
+ splitting, since 32 is the most popular size
+ o blocks of size 32 are now candidates for smaller block
+ coalescing
+ o the IN_BUCKET check was changed to just make sure that the
+ size isn't too big for the bucket, since the `busy block'

+ meaning that the old check would fail and cause a panic when
+ a chunk allocated in such a way was freed
+ o bin sizes are now precomputed and looked up in an array

+ o moved the _mstats declaration here to avoid the stats code

+doc/bash.1
+ - remove the `.' from the sample $PATH value
+
+parse.y
+ - make sure parse_compound_assignment prompts with $PS2 if it reads
+ a newline while parsing the compound assignment statement. Bug
+ reported by Stephane Chazelas
+ - parse_string_to_word_list now takes a new second argument: `int flags'
+ - new parser state flag: PST_COMPASSIGN; indicates that the shell is
+ parsing a compound assignment statement
+ - parse_string_to_word_list turns on PST_COMPASSIGN if `flags' arg
+ has low bit set
+ - turn PST_COMPASSIGN on and off in parse_compound_assignment
+
+externs.h
+ - change prototype declaration for parse_string_to_word_list
+
+arrayfunc.c
+ - change call to parse_string_to_word_list to add new flags arg
+
+general.c
+ - assignment() takes a new `flags' second argument

+ starter character (for parsing compound array assignments)
+
+general.h
+ - add new argument to prototype declaration for assignment()
+
+parse.y,{subst,variables}.c, builtins/{setattr,declare}.def
+ - change calls to assignment() (parse.y calls with flags == 1 when
+ parser_state inlcudes PST_COMPASSIGN)
+
+arrayfunc.c
+ - in assign_array_var_from_string(), don't treat an expanded word
+ of the form [ind]=value specially unless the W_ASSIGNMENT flag is
+ set. This means that words that are the result of expansions but
+ happen to have the same format as compound assignment statement
+ words will not be treated as such. For instance
+
+ v='[12]=foobar'
+ a=( $v )
+
+ will result in a[0]='[12]=foobar' instead of a[12]=foobar. This
+ is closer to how `regular' assignment statements are treated and
+ compatible with ksh93. Bug reported by Stephane Chazelas
+
+shell.c
+ - new --protected argument, disables command substitution when used
