2300 space in alias; if alias does not end in a space, return a fake
2301 space to keep the current alias in the source list - this allows
2302 recursive alias detection; set SF_ALIAS in next source if alias
2303 does end if space.
2304 * lex.c(yylex): deleted expanding_alias, rec_alias_cnt and
2305 rec_alias_table variables; check for recursive aliases by checking
2306 the source list; don't use EXPALIAS flag; if SF_ALIAS is set in
2307 current source, set ALIAS flag and clear SF_ALAIS; deleted global
2308 alias variable.
2309 * table.h: deleted EXPALIAS define.
2310 * main.c(shell): changed s->echo to set/clr of SF_ECHO in s->flags.
2312 * table.h: added aliases and keywords tables; deleted lexicals table
2313 (POSIX says they are separate).

2315 to initkeywords(); changed all calls; add to keywords table instead
2316 of lexicals table.
2317 * main.c(main): initialized aliases/keywords tables; deleted
2318 initialization of lexicals table.
2319 * c_ksh.c(c_whence,c_alias,c_unalias),lex.c(yylex): use
2320 keywords/aliases tables instead of lexicals table; removed unneeded
2321 type == CALIAS checks.
2323 * var.c(getint): new function, largely take from strint().
2324 * var.c(strint): call getint() to do most of the work; if vq
2325 was an allocated string, free the string and clear the alloc
2326 flag.
2327 * var.c(intval): call getint() instead of strint().
2329 * mail.c(mcheck): use getint() instead of strint() when getting
2330 value of MAILCHECK.
2332 * var.c(skip_varname): added argument to allow array references;
2333 changed all calls.
2334 * var.c(set_array): remove valid variable name check - done in
2335 parse_args().
2337 * var.c(strint): check if getspec()/setspec() need to be called.
2338 * var.c(intval): remove getspec()/INTEGER checks - let strint() do it.
2340 * var.c(skip_wdvarname,is_wdvarname,is_wdvarassign): new
2341 functions.
2342 * lex.h(VARASN): new define indicating variable assignment expected,
2343 currently used to parse "x[1 & 2]" as one token - may be used
2344 in future in returning AWORD (assignment word) to the parser.
2345 * lex.c(yylex): Subst: case '[': use is_wdvarname() in determining
2346 whether to parse an array dereference; do not require an = after the
2347 dereference (typeset -r x[1 & 2] is legal).
2348 * syn.c(many functions): pass VARASN to token/musthave/tpeek/synio
2349 when ever the next token might be the first word of a simple
2350 command.
2351 * syn.c(get_command): case LWORD: use is_wdvarassign() to distinguish
2352 variable assignments from normal arguments; allow aliases after
2353 redirections and variable assignments; generate syntax error
2354 for "foo=bar bogusfunction()"; allow array variables in for
2355 and select statements.
2356 * lex.c: make global alias variable static (no longer used by
2357 get_command()).
2359 * syn.c(get_command): put MDPAREN into its own case.
2361 * lex.c(yylex): deleted place holder for tilde expansion.
2363 * tree.h(struct tree): added noexpand field for
2364 alias/export/readonly/typeset.
2365 * syn.c(newtp),tree.c(tcopy): initialize/copy noexpand field.
2366 * syn.c(get_command): case LWORD: set noexpand if assign_command()
2367 returns true.
2368 * syn.c(assign_command): new function - returns true if command
2369 is alias, export, readonly or typeset.
2370 * exec.c(execute): case TCOM: don't pass DOTILDE flag when
2371 expanding t->vars; don't do field splitting/globbing/tilde expansion
2372 of t->args if t->noexpand is set.
2374 * table.h: re-grouped the struct tbl flags into common, variable,
2375 funtion, builtin/alias, etc (some values overlap); new flag
2376 names: KEEPASN (was overloaded with TRACE) and NOEXPAND.
2377 * exec.c(comexec,builtin): changed TRACE to KEEPASN.
2379 * tree.c(tcopy): when copying t->str, use strsave(), not wdcopy()
2380 if not copying a TCASE.
2382 * c_ksh.c(c_typeset): added -p flag for POSIX export/readonly.
2384 * eval.c(expand): expand tilde in place; don't do tilde expansion
2385 on results of substitution (POSIX); only do tilde expansion
2386 if login name is unquoted (POSIX); don't check for fdo&DOTILDE
2387 when a word is completed.
2388 * eval.c(tilde): changed to return home directory of a given login name
2389 (taking care of null/+/-) (old version copied string, scanning
2390 for, and replacing, magic tildes).
2392 * exec.c(findcom): don't create commands table entries when
2393 not inserting; when doing access test of tracked alias,
2394 check for ISSET, not ALLOC (but test ALLOC before calling afree).
2395 * exec.c(search): use strcpy() instead of loop.
2397 Mon Aug 15 14:46:58 NDT 1994 Michael Rendell (michael@panda.cs.mun.ca)
2399 * c_ksh.c(c_print): added at&t ksh -R flag; deleted -e flag;

2412 * var.c: added var field to struct Expand and struct SubType; deleted
2413 struct SubType.name field.
2414 * var.c(expand): case OSUBST: use x.var/st->var field to save result
2415 of global() for use in case CSUBST - this avoids problems with
2416 x[i+=1] being evaluated twice; check to see if value is being
2417 assigned to non-variable (eg, ${*:=aja}) or read-only variable.
2418 * var.c(varsub): set value of xp->var; possibly generate error if
2419 FNOUNSET set when expanding ${#*}, ${#var}, or ${#array[*]}.
2421 * table.h: added struct tbl.areap field to get rid of lastarea
2422 problems; deleted lastarea variable; changted all refernces

2456 integer variable; set ISSET if parsing succeeds.
2458 * expr.c(tempvar): set vp->val.i to 0.
2459 * expr.c(token): when skipping a literal number, don't allow _;
2460 use isspace() to skip.

2605 ksh_getopt (shorter); changed to use state structure instead
2606 of static variables; changed all calls; optionally allow + to

2649 to put job; changed all calls to put_job_on_front and
2650 put_job_on_end to use this; put background processes just
2651 after stopped jobs (instead of at end) (POSIX).
2652 * jobs.c(put_job_on_front,put_job_on_end): deleted.
2654 Tue Jul 19 10:33:55 NDT 1994 Michael Rendell (michael@panda.cs.mun.ca)

2768 messages.
2770 * jobs.c(exchild): remove !XPIPEI condition - we now close pipe so
2771 pipeline doesn't have to call waitlast().
2772 * exec.c(execute): case TPIPE: no need to restore 0 or call waitlast()
2773 since exchild() handles everything.
2775 * jobs.c(remove_job): set last_job to 0 if we are removing it.
2776 * jobs.c(waitlast): check if last_job is 0.
2778 * jobs.c(struct job): combined started, waiting, interactive

2785 Wed Jul 13 09:28:34 NDT 1994 Michael Rendell (michael@panda.cs.mun.ca)
2787 * main.c(main): when checking if FMONITOR set on command line,
2788 use 127 instead of -1 (signed vs unsigned char problem).
2790 * tree.h: renumbered, XEXEC, XFORK, ... and DOBLANK, DOGLOB, ...
2791 to use bits in order (instead of 0 5 2 4...).
2792 * jobs.c(j_init): don't set sigtrap[SIGCHLD].sig_dfl = 1 as a
2793 forked child may be a shell that needs to trap SIGCHLD.
2795 * tree.h(XPCLOSE,XCCLOSE): flags for close in parent, close in child.
2796 * jobs.c(exchild): added third argument - a file descriptor - if

2798 in child.
2799 * exec.c(execute): pass input side of pipe to exchild() so it can
2800 be closed in the child.
2802 Tue Jul 12 10:21:57 NDT 1994 Michael Rendell (michael@panda.cs.mun.ca)
2804 * main.c(main): let ignoresig() handle SIGTERM.

2817 * made pdksh-4.9+mun.4 distribution
2819 * Makefine.in: added $(LDSTATIC) to LDFALGS to make static
2820 linking easier (suggested by sjg); use cp -p when creating
2821 distributions to preserve file dates.
2822 * configure.in: set LDSTATIC in Makefile if present in environ
2823 when configure is run.
2825 * sigact.c(sigsuspend): when calling 4.2bsd sigpause, pass *mask,

2876 * jobs.c(killpg),configure.in: restored use of killpg() - some
2877 systems don't understand kill(-pgrp, signal) (ultrix 2.2);
2878 added test for killpg() in configure.in.
2880 * trap.c(inittraps): changed initialization of sigtraps - was
2881 using -1 in deftraps[] as end of table marker but some systems
2882 (eg, ultrix 2.2) define signals with -1 values (SIGPWR).
2884 * Makefile.in(mandir,install): fixed mandir value; added /
2885 in man installation; prefixed ksh.1 with $(srcdir).
2887 * jobs.c(j_init): Ignore failure of TIOCSETD.
2889 * misc.c(options[]): changed "vicomplete" to "vitabcomplete".
2891 * emacs.c(x_e_putc,x_e_puts,x_debug_info): x_e_putc()/x_e_puts() are
2892 the x_putc()/x_puts() functions from ksh4.9 edit.c (they got lost
2893 in the merge); same for x_debug_info(); changed x_e_putc/x_e_puts

2907 * syn.c(get_command): increment/decrement func_parse when parsing
2908 functions.
2909 * main.c(remove_temps,reclaim,leave): added remove_temps(); make
2910 reclaim() call remove_temps(); make leave() clean up function
2911 here documents.

2923 flag.
2925 * c_sh.c(c_times): combined some printfs().
2927 * jobs.c(j_jobs,j_kill,j_resume,waitfor): block SIGCHLD before
2928 calling j_lookup() or looking at jobs list - avoids potential
2929 problems with remove_job() being called in signal handler.
2931 Sun Jul 3 11:09:01 NDT 1994 Michael Rendell (michael@panda.cs.mun.ca)
2933 * exec.c(do_selectargs, selread, pr_menu): re-wrote do_selectargs to
2934 let c_read() to most of the work; deleted selread; make pr_menu
2935 calculate width/ncolumns each call so select can be used recursively.
2937 * configure.in, aclocal.m4(KSH_TERMIOS_H, KSH_TERM_CHECK): replaced
2938 KSH_TERMIOS_H with KSH_TERM_CHECK; removed calls to

2941 * main.c(main), sh.h: move getcwd() declaration to sh.h.
2943 * eval.c(expand,varsub): added XNULLSUB case to deal with "$@"
2944 (and "${foo[@]}") when $# (or ${#foo}) is 0.
2946 * eval.c(expand,varsub): removed free_me field - let reclaim() take
2947 care of it.

2951 * var.c (setstr): don't set ALLOC flag if vp.s is NULL.
2953 Thu Jun 30 10:16:44 NDT 1994 Michael Rendell (michael@panda.cs.mun.ca)
2955 * c_sh.c(c_read): ignore null characters; use builtin_getopt()
2956 instead of explicit parsing; removed -e option (neither at&t ksh
2957 nor POSIX have this); added -s option (put line in history, at&t ksh);
2958 if no variable specified, use REPLY (at&t ksh).
2960 * exec.c(do_selectargs): use Xstring macros to deal with saving
2961 input (was static, growing, buffers); flush shl_out after
2962 shellf().
2964 * vi.c(expand_word,complete_word): deleted call to free_edstate
2965 since already done by restore_edstate().
2966 * var.c(global): in 'if !letter(c)' block, deleted !c from
2967 'if (!c || !n[1])' - don't know why it was added since it makes
2968 no difference to what is returned.
2970 * syn.c(dogroup): removed onlydone argument since it is only
2971 used in the while/until statements, where "while command; done"
2972 is not allowed anyway; Changed all calls.
2974 * misc.c(options[]): allow -i to be specified on the command
2975 line.
2977 * exec.c(iosetup): if stderr (fd 2) is being re-directed,
2978 re-open shl_out to clear any errors.
2979 * main.c(quitenv): if restoring fd 2, clear any write errors
2980 * io.c(initio): initialize shl_out, shl_spare for writing
2981 (was SHF_GETFL).

2990 * sh.h(reallyquit): deleted reallyquit
2992 * exec.c(comexec), main.c(main), misc.c(change_flag), jobs.c:
2993 ifdef'd use of FMONITOR.

2999 error code, added defines for error codes, added error message
3000 array; changed all calls to use new conventions.

3002 to specify if notification messages should be suppressed.
3003 * jobs.c(j_waitj): added flags argument instead of intr argument;
3004 added JW_STOPPEDWAIT flag to wait for stopped jobs to complete;
3005 added JW_NONOTIFY flag to suppress notification of normal
3006 job termination.
3008 Tue Jun 28 16:13:10 NDT 1994 Michael Rendell (michael@panda.cs.mun.ca)
3010 * c_ksh.c(c_jobs): added -n and -p options, allow job ids to be
3011 specified for -l option.
3012 * jobs.c(j_jobs): added new arguments to deal with -n and -p options.
3014 * shf.h(SHF_BSIZE): reduced size to 512 to reduce memory requirements
3015 (I/O is used mostly for one line messages).
3017 * config.h.bot: removed necessity for tty process groups to define
3018 JOBS, added necessity of signal blocking/pausing.
3020 Mon Jun 27 21:49:52 NDT 1994 Michael Rendell (michael@panda.cs.mun.ca)
3022 * jobs.c(exchild,j_print,j_waitj,j_jobs,check_job): exchild() - removed
3023 commented out shf_flush() calls; j_print() - print a space between
3024 status reports when lflag < 0, changed flag argument to use
3025 long/medium/short defines; Changed Job.notify field to use
3026 long/medium/short defines; j_waitj() - instead of calling j_print(),
3027 set j->notify to print the job; j_jobs() - clear j->notify so user
3028 won't be notified twice if a job finishes before a jobs command;
3029 check_job() - put job on front of list only if it is stopped.
3031 * main.c(main): pass flag to j_init() indicating if -m flag set/cleared
3032 on command line; don't initialize ttyfd.
3033 * sh.h: delete ttyfd.
3034 * jobs.c(j_init,ttyfd,check_job): made ttyfd static; re-worked j_init()
3035 to initialize ttyfd, initialize FMONITOR if not set by command line,
3036 initialize shl_j for asynchronous job notification;
3037 check_job() - use shl_j, look through saved fds to find real
3038 standard-error.
3040 * jobs.c(TTY_PGRP, ttypgrps_ok): modified conditions so job control
3041 is useful without tty process groups; added ttypgrps_ok flag that
3042 indicates if tty process groups should be set up; modifications so
3043 job control useful if ttypgrps_ok not set.
3045 * main.c(main): set FTALKING if 0 and 2 are tty as specified in POSIX
3046 (was 0 and 1).
3048 * misc.c(parse_args): do POSIX option processing for -A, -c and -o
3049 (allow -onoglob, -ctrue).
3050 * main.c(main): don't set up shl_stdout before/after parse_args() since
3051 lone -o on command line no longer accepted; remove code to allow
3052 -c with no options to read from stdin (at&t khs does this but POSIX
3053 requires an option to -c).
3055 Thu Jun 23 17:46:54 NDT 1994 John Rochester (jr@panda.cs.mun.ca)
3057 * trap.c(cleartraps): added special case for clearing trap 0 from

3063 missing option; reset state if argv is 0.
3064 * c_ulimit.c(c_ulimit): let builtin_getopt() print error messages.
3065 * exec.c(call_builtin): call builtin_getopt() with 0 argv.
3067 * c_sh.c(c_unset): added -v option (POSIX); use builtin_getopt() to
3068 parse arguments; removed bogus comment about global() and special
3069 variables; don't allow read-only variables to be unset (POSIX).
3071 * var.c(unset, unsetspec): when unsetting a special variable, call
3072 unsetspec(); unsetspec() new function.
3073 * mail.c(mbset, mcheck): check that path is not 0 before calling stat
3074 (so mbset() can be called with 0 when MAIL is unset); deleted #if 0'd
3075 declarations of munset, mballoc and maddmsg.
3077 * misc.c(parse_args): pass argv+i+1 to set_array (not argv+i); when
3078 skipping arguments, leave i just before the NULL.

3082 * shf.c(shf_close): always used to return EOF.
3084 * trap.c(trapsig): skip error handlers when checking for PARSE or LOOP.

3089 (IFS white space).
3090 * c_sh.c(c_read): print continuation prompt if line ends in backslash;
3091 multiple non-white-space IFS chars delimit fields; strip trailing
3092 IFS-white-space from last variable; watch out for backslash followed
3093 by EOF.
3094 * eval.c(expand): only do field splitting on the results of
3095 parameter/command substition (POSIX, !v7-sh); multiple
3096 non-white-space IFS chars delimit fields.
3098 * eval.c(expand,alt_expand): removed NOALT tests since it could
3099 never be set; added return after call to alt_expand() in expand().
3101 Mon Jun 6 10:12:41 NDT 1994 Michael Rendell (michael@panda.cs.mun.ca)
3103 * misc.c(setctypes, initctypes): setctypes - don't allow leading null
3104 in IFS (IFS="" could cause problems, 0 is already added);
3105 initctypes - don't use a leading null.
3107 * sh.h, eval.c: move definition of ifs0 from eval.c to sh.h; handle
3108 null ifs0.
3109 * var.c(setspec): set ifs0 to first character of IFS.
3111 * lex.c(yylex): when parsing ${..}, array references were not being
3112 null terminated.

3116 * var.c(export): changed to use memcpy() instead of loops.
3118 * eval.c(varsub, expand): check for #foo[@] in addition to #foo[*];
3119 handle ${foo[*]} and ${foo[@]} - added free_me field to struct Expand
3120 so pointer vector can get freed.
3122 * c_sh.c(c_dot), main.c(include): set up positional parameters if
3123 any are specified; Added argc,argv args to include(); changed all
3124 calls to include(); change include() to return 0 or 1 - caller
3125 can check exstat if desired; c_dot() should return 1 if can't open
3126 file (was -1).
3128 * c_sh.c(c_brkcont): warning message could call getn() with NULL - save
3129 original number and print it.
3131 * main.c(main): set $0 to first argument when -c used, ie,
3132 "sh -c cmd-string this-is-$0 argumernts..."
3134 * exec.c(iosetup): print "cannot open" if IOHERE fails.
3136 * io.c(errorf): set exstat to 1.
3138 * exec.c(search): assume mode is R_OK or X_OK (not 0/1 - 0 is F_OK, we
3139 want R_OK); changed all calls to pass R_OK/X_OK.
3140 sh.h: define R_OK,W_OK,X_OK,F_OK if not defined.
3141 eaccess(): changed all calls to use [RWXF]_OK.
3143 * sh.h(flag[], shell_flags[], Flag()): Renamed flag[] array to
3144 shell_flags[] to avoid conflicts with other uses of flag; Changed
3145 all references to flag[] to Flag(); defined Flag() to cast its arg
3146 to an int (for old pcc based C compilers).
3148 * vi.c(iswordch): use letnum() instead of isalnum || _.
3150 * misc.c(parse_args): call set_array() to deal with -A flag.

3156 * eval.c(substitute): afree(s).
3158 * var.c(global,local), sh.h: ARRAYMAX: new define - max index of an
3159 array; changed 511 constants to this; changed global() and local()
3160 to use array_ref_len() instead of arraysub().
3162 * expr.c(token): deleted unneeded arraysub() decl.
3164 * lex.c(arraysub), proto.h: made static, removed unused arguments,
3165 changed callers; removed prototype from proto.h.

3171 * made pdksh-4.9+mun.2 distribution
3173 * Makefile.in: added RCSFILES macro and rcs-ci target.
3175 * configure.in: add termio.h to the AC_HAVE_HEADERS() call.
3177 * sh.h, main.c, edit.c, misc.c: use EXTERN for aperm, x_cols,
3178 builtin_optind and builtin_optarg in sh.h, delete definitions
3179 in main.c, edit.c and misc.c.
3181 * io.c(maketemp): changed sizeof(PATH) to sizeof(path).
3183 * aclocal.m4(KSH_VOID,KSH_DUP2_CHECK): test that a void * variable
3184 can be used (Ultrix 2.2 compiler doesn't do this); added ifdef
3185 HAVE_FCNTL_H to dup2 test.
3187 * aclocal.m4, configure.in, sh.h, tree.c, io.c, shf.c: added
3188 new config test KSH_PROTOTYPES to check for function prototypes
3189 (MIPS RICS/os 5.0 C compiler isn't STDC and it can't mix <stddef.h>
3190 with <varargs.h>). Removed stdarg.h test (now redundent). Changed
3191 all varargs functions to use HAVE_PROTOTYPES instead of
3192 HAVE_STDARG_H && STDC.
3194 * eval.c(alt_scan): changed type of endc param from char to int to
3195 avoid problems with mixing prototype declarations and K&R
3196 definitions.
3198 * main.c(main), sh.h: added plain getcwd() decl to main(), removed
3199 ARGS() version from sh.h (some systems have getcwd() but don't
3200 declare it, some have getcwd() with a size_t arg 2, some have
3201 an int arg 2).
3203 * misc.c(memset,memmove): changed the second memset() to memmove().
3205 * c_sh.c(clocktos): changed #if CLK_TCK ... to if (CLK_TCK.. since
3206 CLK_TCK is not always defined to a number (may be a _sysconf())).
3208 Tue May 31 10:49:16 NDT 1994 Michael Rendell (michael@panda.cs.mun.ca)
3210 * configure.in, Makefile.in: added code to set GCC_WARNFLAGS from
3211 $(srcdir)/Warn-flags if gcc is being used; Took -Wall, etc.
3212 out of CFLAGS, took -Dno_RCSids out of DEFS. Added install.sh to
3213 DISTFILES, grabbed copy of install.sh from autoconf (who grabbed
3214 it from X11R5).
3216 * io.c(errorf,shellf,shprintf),shf.c(shf_fprintf,shf_snprintf),
3217 tree.c(fptreef,snptreef): don't use ansi decls with old style
3218 varargs; changed ifdef __STDC__ to ifdef HAVE_STDARG_H.
3220 * jobs.c(j_init): changed getpgrp() call to getpgID(), defined getpgID()
3221 appropriately for BSD vs POSIX/SYSV getpgrp.
3223 * expand.h, ksh_dir.h, ksh_stat.h, ksh_time.h, ksh_wait.h, shf.h,
3224 tty.h: added RCS $Id: ChangeLog.0,v 1.1 2004/11/20 13:28:11 hnl_dk Exp $'s.
3226 * acconfig.h: updated SIGSET_T comment: unisgned int -> unsigned.
3228 * aclocal.m4(KSH_CLOCK_T,KSH_TIME_T,KSH_SIGSET_T): make sure
3229 type is a word (same fix as was done for more_t, et.al.).
3231 * aclocal.m4(KSH_VOLATILE): check that the compiler can deal with
3232 volatile pointers (dec/pmax ultrix 4.2 compiler can't).
3234 * misc.c(parse_args): added skelatal code for dealing with -A.
3236 * var.c,proto.h(skip_varname): new function; deleted isassign()
3237 function, which is no longer called. Changed typeset(var.c)
3238 to use skip_varname().
3240 * var.c(strint): fail if base is not in the range 2..36; set variable
3241 base according to first base seen; generate an error if a non-alnum
3242 char is seen (1^A was the same as 11).
3244 * var.c(strval): for integer variables, output base if != 10.
3246 * sh.h: fixed typo in x_cols define (#defined -> #define).
3248 Fri May 27 16:49:29 NDT 1994 Micharl Rendell (michael@panda.cs.mun.ca)
3250 * made pdksh-4.9+mun.1 distribution
3252 * finished autoconf'ing source code.
3254 Fri May 20 16:47:06 NDT 1994 Michael Rendell (michael@panda.cs.mun.ca)
3256 * c_ulimit.c(c_ulimit) (was do_ulimit.c(do_ulimit)): major rework;
3257 deal with combinations of getrusage and ulimit, use options at&t
3258 ksh uses (-SHa..).
3259 * misc.c(builtin_getopt): yet another getopt routine for builtin
3260 commands
3261 * misc.c(parse_args), c_sh.c(c_set), main.c(main): custom option
3262 parsing routine for command line/set options. Lots of changes
3263 to main() to incorporate this (easier to follow).
3264 * c_test.c(c_test): added -e (file exists) test.
3266 Fri May 5 12:16:46 NDT 1994 Michael Rendell (michael@panda.cs.mun.ca)
3268 * numerous changes from old Notes.4-9 file:
3269 - c_ksh.c:
3270 - calls to errorf identify what function the error is in
3271 (eg, errorf("print: bad -u option");)
3272 - added array stuff (lots of places)
3273 - table.c
3274 - lex.c
3275 - var.c: +arraysearch(), +basename()
3276 - c_sh.c(c_exit), main.c(shell), sh.h:
3277 - added reallyquit flag to deal with stopped jobs at exit time;
3278 only two exit commands (or eofs) in a row will work. in
3279 shell(), set exstat from execute value.
3280 - c_ksh.c(c_print):
3281 - handle \\ at end of string better (don't skip the null)
3282 - c_ksh.c(c_whence):
3283 - stop looking as soon as we get a failure
3284 - pass flag[FTRACKALL] to findcom() instead of 0
3285 - c_ksh.c(c_alias):
3286 - print '%s alias not found' if not found
3287 - c_ksh.c(c_jobs):
3288 - handle -l option (list pid)
3289 - c_ksh.c(c_kill):
3290 - two column -l output to try to keep it on one screen
3291 - c_sh.c(c_read):
3292 - skip IFS at start of line "echo ' a b' |(read a b; echo $a)"
3293 should print a, not nothing.
3294 - changed EOF check to set all vars to null (same way \n is
3295 handled)
3296 - eval.c(comsub):
3297 - after compile(), return if t is NULL
3298 - use setfileno() instead of fileno(x) = .. (see sh.h changes);
3299 - exec.c(iosetup):
3300 - set exstat if redirect fails
3301 - exec.c(fd_clexec):
3302 - check that fd >= 0
3303 - exec.c:
3304 - change SHARPBANG ifdef code - everyone uses scriptexec().
3305 ifdef is put around open/read/parse code in scriptexec().
3306 [code cleanup]
3307 - exec.c(search):
3308 - eaccess test out side of loop: must be regular file to exec it
3309 (like test in loop)
3310 - eval.c(expand):
3311 - added while getc() == 0 in XCOM
3312 [a null in the output of a file would be treated as eof and
3313 waitlast would not be called]
3314 - eval.c(trimsub):
3315 - '%' subst: use ATEMP, not APERM
3316 - eval.c(tilde): use Xinit et. al., instead of fixed length buffer
3317 - getopts.c(getopt): rename getopt() to ksh_getopt() to avoid
3318 problems with prototypes in system #include files.
3319 - io.c(fopenshf):
3320 - call clearerr(fd) if already open
3321 - use F_GETFL to determine appropriate mode for fdopen() call
3322 instead of opening everything for read/write
3323 - use ifdef _FSTDIO instead of ifdef _BSDI (_FSTDIO is used in
3324 4.4bsd, NetBSD, FreeBSD and other non BSDI environs)
3325 - lex.c(ungetsc): don't decrement if str == null, remove nullstr hack
3326 - lex.c(yylex):
3327 - \ at eol: call Xfree before goto Again
3328 - use memset() to clear ident, instead of while loop
3329 - syn.c(get_command): renamed from command() to get_command() to
3330 avoid conflicts with command(main.c).
3331 - sym.c(get_command):
3332 - allow A=B <alias-name> to work (alias was not being expanded)
3333 - allow `if .. if .. fi fi' to work (no ; after group terminator
3334 (fi , esac, done, ), })
3335 - allow `alias FI=fi ; if .. if .. fi FI' to work (alias
3336 expansion after group terminator)
3337 - do not assume resize returns same pointer
3338 - tree.c(pioact):
3339 - handle IORDWR case
3340 - added leading quote for file in IOHERE case
3341 - var.c(special):
3342 - add MAILCHECK check
3343 - var.c(setspec):
3344 - add MAILCHECK case (doesn't do anything yet)
3345 - var.c(strint):
3346 - handle null vp->val.s
3347 - eval.c(sh.h, expand), misc.c(options[]):
3348 - enable alternations only if alternations flag set
3349 (set -o alternations). This is so (att ksh) scripts that don't
3350 expect alternations won't break.
3351 - added notify option (asynchronous job completion notification)
3352 - added vicomplete to enable tab char as file name completion
3353 char in vi (this is likely to go away - exits for historical
3354 reasons)
3355 - jobs.c, main.c, sh.c, trap.c:
3356 - define/use SIG_HDLR instead of void
3357 - eval.c(expand): alt_expand() does not return a value so don't test
3358 it, just return. Also changed decl of alt_expand() to reflect
3359 reality.
3360 - emacs.c(x_emacs): first return returns random value (i); change to
3361 return 0. Also changed the way interrupts are returned to called
3362 (return -2 means interrupt).
3363 - c_sh.c(c_brkcont): at&t ksh allows breaks/continues outside of
3364 loops, 4.9 prints an error and breaks out of all env's (if, case,
3365 etc.). Fixed to act like at&t (ie, allow bogus continues), except
3366 a warning message is printed. (Some HP-UX shell scripts actually
3367 have continues outside of loops...)
3368 - main.c(shell): parameter s should be volatile as it is used after a
3369 setjmp.
3370 - edit.c(promptlen): handle tabs, backspaces...
3371 - cleaner fix to the ^C/source->line problem: in pprompt(lex.c),
3372 convert ! to source->line+1 (same in promptlen(edit.c)), increment
3373 source->line after a (non-empty, non-eof) line has been read
3374 (before call to histsave()). To be pedantic, also adjust
3375 position of source->line++ in SHIST in case PS9 is ever used.
3376 Remove code in shell(main.c) that does the source->line--,
3377 remove the source->line-- for eof and empty line in from
3378 getsc_(lex.c).
3379 - trap.c(sigtrap[]): do not depend on signal number matching position
3380 in initialization array. Use second table in which order does not
3381 matter to initialize sigtrap[] array. Easier to read/port, and
3382 generally less fragile. requires call to inittraps() in main.c.
3383 - trap.c(cleartraps): need to clear Sigact flags/mask after use
3384 (actually, declare a local struct sigact and use that instead of
3385 Sigact)
3386 - exec.c(execute): case TSELECT: no USE_SIGACT code for call to
3387 signal(); case TPIPE: don't call waitlast() if XXCOM since
3388 waitlast() will be called in expand(); 4.9 code that set and
3389 then cleared the XEXEC flag in the TPIPE case not added since
3390 it was ifdef'd out, also the code to not exit if XPIPEI flag
3391 set was not added; 4.9 XXWHL flag not added (don't flush stdin
3392 if in a while loop) since this problem fixed (I hope) by shf stuff.
3393 - ttyfd{sh.h/lex.c}: use EXTERN/_I_ to initialize ttyfd. Remove from
3394 lex.c
3395 - interrupted reads: instead of testing sigchld_caught after reads
3396 fail, continue them if errno == EINTR.
3397 - edit.c(x_getc): check for EINTR, and continue reading if so.
3398 - lex.c(getsc_): check for EINTR, and continue reading if so.
3399 (don't check return of x_read() - check has already been done)
3400 - exec.c(selread): check for EINTR, and continue reading if so.
3401 - history changes:
3402 - history.c:
3403 - histrpl(): bounds check doesn't take global flag into
3404 account - move check into loop and past loop.
3405 - c_fc(): if pattern is the empty string, histrpl()
3406 goes into infinate loop. Start searching for = after first
3407 char (this is what at&t ksh seems to do).
3408 - c_fc(): `fc -l first' should list at most 16
3409 commands according to at&t manual.
3410 - findhist(): re-wrote: shorter, easier to follow. Now
3411 returns an int. (used only by vi code)
3412 - use COMPLEX_HISTORY's allocated history array in
3413 EASY_HISTORY: common init_histvec(), sethistfile() and
3414 sethistsize() functions.
3415 In the process, hist_open() went away. Use histsize
3416 instead of HISTORY in hist_init() and hist_finish()
3417 #ifdefs in lex.h, table.h,
3418 var.c disappear, history variable definitions in lex.c
3419 disappear.
3420 - hist_init(COMPLEX_HISTORY): move hstarted = 1 to after the
3421 FTALKING test.
3422 - hist_finish(): don't open hname if its null
3423 - histrpl(): made static, use ARGS in decl
3424 - made current and curpos static
3425 - changes to allow embedded newlines in commands:
3426 - histsave(): trash only trailing newline
3427 - hist_init(): read in null terminated lines instead of
3428 newline terminated
3429 - hist_finish(): write null terminated lines
3430 - make multiple line command appear in single history line
3431 (EASY_HISTORY only):
3432 - added histappend() to append new command to last
3433 command
3434 - added call to histappend() in getsc_(lex.c) (also: only
3435 adjust source->line if not multiline).
3436 - lex.h:
3437 - remove second decl of history if !EASY_HISTORY
3438 - tree.c(ptree): case TCOM: check if t->vars or t->args is 0
3439 - vi.c(x_vi): ^D anywhere in command line is eof ($ foobar^D exits).
3440 at&t ksh ignores ^D in middle of line
3441 - edit.c:
3442 - don't need to include string.h - included in stdh.h
3443 - init_editmode(): in at&t ksh, VISUAL takes precenence over
3444 EDITOR, so put it first. Also, at&t ksh doesn't use FCEDIT so
3445 trash it.
3446 - moved initialization of ed_* from x_read() to x_init() since
3447 thats where they are set from tty structs.
3448 - x_init(): set ed_intrc, ed_quitc for _BSD & _POSIX_TERM ifdefs
3449 - send output to shlout (instead of stdout - at&t ksh writes to
3450 stderr)
3451 - made x_do_init static.
3452 - exit.c(x_getc), lex.c(yylex): restart interrupted reads in
3453 x_getc(), changed read-restart in yylex() to only effect call
3454 to read().
3455 - syn.c(thenpart): then THEN is not optional - generate a syntax
3456 error if no THEN. (ie, `if true ; fi' is not legal).
3457 - syn.c(get_command): don't accept keywords after re-directory (eg,
3458 `> /dev/null if true ; then echo hi ; fi' is not legal).
3459 - vi.c: handle \ and ^[ in command mode ala at&t ksh (filename
3460 completion)
3461 - syn.c(thenpart), syn.c(elsepart): calling token(0) when they want a
3462 keyword (always worked 'cause tpeek() is always called before, with
3463 the keyword flag). Fix: call token(KEYWORD|ALIAS) (at&t ksh does
3464 alias expansion here). Question: pass CONTIN as well?
3465 - syn.c(get_command): LWORD/MPAREN case: do alias expansion when
3466 getting open brace ({). CASE case: ditto for `in' and `esac'.
3467 IF case: ditto for `fi'. FUNCTION case: dito for open brace ({).
3468 - syn.c(dogroup): alias expansion when getting `do' and `done'.
3469 - syn.c(wordlist): alias expansion when getting `in'.
3470 - syn.c(nested): alias expansion when getting `)', `}'
3471 - syn.c(casepart): alias expansion when getting `esac' or `;;'.
3472 Also removed use of cf variable - it does nothing.
3473 - eval.c(expand): case CSUBST: '#'/'%' - increment st so nested
3474 substitutions work.
3475 - var.c(typeset): INTEGER && no assignment: memory was being freed
3476 and then used (there was even a comment saying it was being
3477 done...)
3478 - lex.c, lex.h, exec.c, main.c:
3479 added shf_{open,fdopen,close,gets}() routines so stdio wasn't
3480 used. When reading a command file under osf/1, stdio would
3481 mess up the read pointer when a child exited: the exit flushed
3482 all open files and flushing a file open for reading changes the
3483 current read position (does a seek to where the next char would
3484 be read). This position is then used by the parent process,
3485 who thinks the read position is still at the end of the buffer
3486 it read.
3487 - c_sh.c:
3488 use shf_*() routines avoids two bugs in read:
3489 - on sunos 4.1.3, a read would gobble up a stdio buffer and
3490 never put it back (ie, lseek backwards). Neither a
3491 fflush() nor a fseek(x, 0L, 1) fixed the problem.
3492 (see Bug 26)
3493 - on linux, stdio knows its current offset and seeks there
3494 before reading a buffer. This causes grief when the shell
3495 replaces file descriptors behind stdio's back (ie, all the
3496 time).
3497 $ read x << EOF
3498 hi
3499 EOF
3500 $ cat > /dev/tty << EOF
3501 1:abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
3502 2:abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
3503 3:abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
3504 EOF
3505 $
3506 the cat picks up reading at the offset where the read
3507 command left off (ie, at bcdefg... - the 1:a are skipped).
3508 - exec.c(comexec): built-in c_exec && no args: close the saved fd's
3509 (were thrown away). Also, set close-on-exec flag for fd's > 2,
3510 as per at&t manual.
3511 - lex.c(yylex): only accept 1 digit before a redirection (eg, 1> is
3512 ok, 1abc> is not)
3513 - exec.c(iosetup): only accept 1 digit after a dup-redirection
3514 (eg, >&1 is ok, >&1abc is not)
3515 - exec.c(iosetup): use O_APPEND flag for >> redirections; use O_CREAT
3516 flag for <> redirections. (re-organized to accumulate open() flags
3517 and do one open() call); changed error message to know about dup
3518 failing.
3519 - c_sh.c(c_umask): umask should have leading 0 - doesn't when umask
3520 has 3 digits (eg, `umask 222; umask' prints 222 instead of 0222)
3521 - c_sh.c(setsig): declare local struct sigaction and use it so
3522 sa_flags doesn't have to be cleared (also to try to keep away from
3523 global vars).
3524 - main.c(main):
3525 - don't go set TALKING if name starts with -.
3526 - read $HOME/.profile (not .profile)
3527 - main.c(main): re-wrote option parsing code
3528 - edit.c(init_editmode): don't check FCEDIT
3529 - if set -o vi/emacs/gmacs on command line, don't set edit mode from
3530 FCEDIT/EDITOR/etc.
3531 - var.c(setspec): FCEDIT should not magicly change edit mode; VISUAL
3532 and EDITOR should (EDITOR only if VISUAL is not set)
3533 - changed noclobber char from ! to | (this is what at&t ksh uses)
3534 - exec.c(iosetup): use O_EXCL flag if FNOCLOBBER set and >| not used
3535 - c_sh.c(c_set): don't clear FERREXIT if FTALKING is set; although
3536 some ksh manuals say -e is ignored for interactive shells, they
3537 all seem to honour the -e flag for interactive shells.
3538 - vi.c: reset history position to the end after a line is modified
3539 - `(( 1 + 2 ))' no longer prints `+: bad expression'!
3540 - lex.c(yylex): added parenthesis counting so `(( ((1+2)) ))' no
3541 longer generates a syntax error
3542 - expr.c(intvar): if strint() fails, give bad number error
3543 (`let 1+foo' should fail)
3544 - `echo hi 1abc123> /dev/tty' no longer interpreted as
3545 `echo hi 1> /dev/tty' (is `echo hi 1abc123 > /dev/tty')
3546 - `echo hi 1<> /tmp/does-not-exist' now works (used to say cannot
3547 open)
3548 - c_sh.c(c_umask): umask now takes symbolic arguments (g-r, +w, etc.)
3549 - c_ksh.c(c_whence): pass flag[FTRACKALL] to findcom() instead of 1.
3550 - `echo hi >< bar' now produces an error
3551 - jobs.c(j_lookup): now checks for ambiguous job specifications;
3552 callers now get an error message.
3553 - c_ksh.c(c_fgbg): multiple jobs can be specified
3554 - emacs.c(x_transpose): move past transposed chars like (gnu) emacs
3555 does
3556 - main.c(main): don't copy initcoms (messes up memory allocated for
3557 shf_iob[] in initio(), should not be necessary)
3558 - main.c(main), var.c(import), var.c(typeset), c_ksh.c(c_alias),
3559 expr.c(token), misc.c(strnsave): added strnsave() function; use it
3560 instead of writing nulls in the middle of strings; main() no longer
3561 copies startup commands before executing them.
3562 - vi.c: wbuf[] no longer a fixed size (was hard coded to 80 chars).
3563 - alloc.c(aresize): if passed a null pointer, don't free it
3564 - expand.h: restored usage description and NOTE from previous version
3565 - alloc.c, table.h, table.c:
3566 - changed struct fields named `free' to nfree (struct table) and
3567 freelist (struct Block) to allow memory debugging
3568 (involves #defining free)
3569 - main.c(main): smart initialization of PWD (ensures it is always
3570 valid).
3571 - lex.h, table.h, tree.h: removed redundent function declarations
3572 (were also in proto.h)
3573 - sh.h: increased LINE from 256 to 1024
3574 - main.c(include), sh.h(E_INC), c_sh.c(c_return): added hack so a
3575 return in a included file returns to the includer instead of
3576 exiting the shell. Very useful in $ENV scripts and profiles,
3577 eg, so the whole script does not have to be parsed for
3578 non-interactive shells.
3579 This is not compatible with the at&t ksh, whose man page says
3580 return is the same as exit outside of functions. May be modified
3581 in the future. (note that at&t ksh parses a .'ed file before
3582 executing anything, so a premature return would not speed its
3583 parsing, which is why the return hack was added to pdksh)
3584 - exec.c(iosetup): don't save fd if already saved (and don't
3585 generate an error)
3586 - exec.c(findcom): in if (..ALLOC && eaccess), test for
3587 ALLOC redundent - always call afree()
