In load-subs: Print an error message if the file is unreadable or doesn't exist, UNLESS load-subs is called with no arguments. In that case only print an error if the file exists but isn't readable. Still prints an error either way if zephyr reports a failure. [BZ 19]

20       
212.1.9
22        Include /usr/include/kerberosIV if it's found
23       
242.1.8
25        Do OLC formatting for anything coming from olc.matisse
26        Improvements to popup size algorithm (from gildea)
27        Improved 'show colors' with non-colored labels
28       
292.1.7
30        The colorclass command is added, to make colorization easy
31        Handle MIT Athena OLC zephyrs correctly
32        Updated ktools website / bug address
33        Do ntohs() when printing zephyr port in zephyr info
34        Updated man page
35       
362.1.6
37        Fixed three bugs found by Valgrind.
38        Fixed a case where doing "aim addbuddy" instead of "addbuddy aim"
39          would cause a segfault.
40        pexec will now incrimentally display data as it is output
41          by the child process.  Additionally, commands running under
42          pexec may now be killed by quitting out of the popless window.
43        Added muxevents select loop dispatcher.  File descriptors may
44          be registered with muxevents and handlers will be dispatched
45          to when data is available for non-blocking read/write/except.
46        Switched the stderr_redir stuff to use muxevents.
47        Print C-\ correctly (from gildea)
48        Dropped first brace in muxevents functions for consistency
49        Catch SIGHUP and SIGTERM and do a proper logout
50       
512.1.5
52        Added a licence
53        The 'personalbell' variable can now be set to 'on' 'off' or
54          the name of a filter to match against
55        The 'loglogins' variable now controls whether login/logout
56          messages are logged.  It is off by default.  For now this
57          affects only AIM messages, later zephyr login/logout messages
58          will also be logged if this is set to 'on'
59        Added 'show license'
60       
612.1.4
62        Normalize and downcase AIM names for logging
63        Fixed a bug where sending a null zsig could cause a crash
64        Better 'away' toggling if only one protocol is away.
65
662.1.3
67        Added perl filter elements.  Similar to having "filter <subfilter>"
68          in a filter, you may also have "perl <functionname>"
69          where <functionname> is passed an owl::Message object and
70          returns 0 or 1 depending on whether the message matches
71          that element of the filter.
72        Don't print an error about loading subs if there is no
73          .zephyr.subs
74        Do the initial zephyr_buddy_check when pseduologin set to true.
75        Updated man page
76       
772.1.2
78        removed unused filter_depth variable
79        Fixed memory bug on receiving pings
80       
812.1.1
82        Filters of filters now work.
83        Removed the "possibly not readable" part of the config parsing
84          error
85        In the sepbar, reverse video the view name when it's not set to
86          view_home (as opposed to the static 'all').
87        The '!' key (bound to 'view -r') now creates a negative version of
88          the current view and switches to it.  i.e. "show me all the
89          messages that are not these"
90        Added the 'ignorelogins' variable
91        Log when outgoing personal message fails
92        Removed file descriptor from sigpipe catcher printer just for now,
93          since the field does not exist on OSX
94        Added an ifndef for socklen_t in libfaim/ft.c
95        Added the 'aim search' command.  The popup on callback may be
96          dangerous, should switch to an admin msg for results, or add a
97          new event queue
98        First pass at AIM away messages.  It is a little different from
99          what most clients seem to do, in that an away reply is sent for
100          each message received.  Most clients only reply to the first one
101          per away-session.
102        Now have a set of 'aaway' commands and variables just like the
103          'zaway' ones (except that changing the 'aaway' variable talks to
104          the server)
105        The new 'away' command does everything for both AIM *and* zephyr.
106          There is a known funkiness here, where if you turn one away on,
107          and then use 'away' (or 'A') to toggle, you will turn on off and
108          the other on.  Just leaving it for now.  Should do better in the
109          next patch.
110        The 'A' key is bound to 'away'
111        Status bar can now read AWAY, Z-AWAY or A-AWAY.
112        Changed C-n to scroll down just a line in popless
113        If the config exists but is not readable, print an error before
114          exiting
115        Only print forced AIM logout message once.
116        Don't bind F1 to help in edit context
117        Fix bug in 'getsubs' with no tickets
118        New code for getting users from .anyfile
119        Added the 'pseudologins' variable, and code to do it
120        new attributes 'pseudo' 'logintty' and 'loginhost'
121        Don't print extra new lines in popless_file
122        New zephyr_get_field function
123       
1242.0.14
125        Fixed missing word in startup message
126        Better 'status' command
127        Use '+' for popwin corners when 'fancylines' is off
128        Allow TERMINFO to be overridden in the envrionment
129        Command line arg -D turns on debugging and deletes previous
130          debugging file
131        Do ~ expansion in 'dump' command.
132        Current directory added to 'status' command
133        Massive changes to libfaim and aim
134       
1352.0.13
136        Changed startup message for new mailing list
137        blist now prints AIM info even if .anyone is unreadable
138        Catch SIGPIPE and print an error rather than crashing.
139                [It's possible that this may have some portability
140                issues under Solaris and we may need to add some
141                configure stuff around SA_SIGINFO...]
142        Handle the case in aim_bstream_send where aim_send returns -1,
143                although there is likely an underlying problem here
144                that would lead to this case.
145        Print the username on aim login failure, not something random like
146                the password.  ;)
147        Un-word-wrap text when sending AIM messages.
148        Replace the main loop continue in the keyboard handler with an else.
149       
1502.0.12
151        Command history now doesn't allow the last entry
152           to be repeated
153        If format_msg returns "" print "<unformatted message>"
154        Better align oneline admin and loopback messages
155        Print an admin message indicating when subscriptions can
156           not be loaded on startup
157        Set aim_ignorelogin_timer to 15 by default
158        Admin message on login/logout of AIM
159        Fixed double quoting in smartzpunt
160        Added timestamp to login/logout messages
161        Fixed replies to loopback messages
162        Fixed smartnarrow on classes/instances with spaces
163        Added the 'loggingdirection' variable
164        All loopback messages log to 'loopback' now
165        Print an error message if trying an invalid color for a filter
166        Fixed bug causing > not to go to end of editwin every time

1682.0.11
169        Updated basic help
170        Display CC: in outgoing CC messages
171        More AIM logout detection
172        Don't proclaim "interfaces changed" on first build.
173        Added the 'loopback' message type
174        Added the 'loopwrite' command
175        Added a timestamp to the default style

189        Added feature for capturing stderr messages
190           from commands and displaying them in the errors buffer.
191        Create an admin message explaning that a zephyr couldn't
192           be sent
193        Better reporting of perl errors (both into the errqueue
194                and also clearing the error after displaying it).
195        Allow default_style to be specified in config.

207        Add owl::login and owl::auth to legacy variables populated for format_msg.
208        Additions to intro.txt and advanced.txt documents.  (Still in progress.)
209        Add base methods for login_host and login_tty
210                and others that return undef.
211        New API for perl message formatting functions. 
212                Legacy variables are still supported for owl::format_msg
213                and owl::receive_msg, but these functions are now also
214                passed an owl::Message object which contains methods
215                for accessing the contents of the message.  See perlwrap.pm
216                (and docs TBD) for the available methods.
217                *** WARNING:  The exact API for owl::Message has
218                *** not yet stabilized.
219        Added "style" command for creating new styles.

222                from list to dictionary.
223        Changed AIM password prompt from "Password:" to "AIM Password:".
224        Messages are reformatted after a window resize to allow styles
225                to take into account the width of the window.
226        When perl throws an error, the message is put in the msgwin
227                if possible.
228        Added perl functions for:       
229                owl::getcurmsg() -- returns an owl::Message object for
230                                    the active message
231                                    in the current view.
232                owl::getnumcols() -- returns the column width of the window
233                owl::zephyr_getrealm() -- returns the zephyr realm
234                owl::zephyr_getsender() -- returns the zephyr sender
235        Made owl::COMMAND("foo"); be syntactic sugar for
236                owl::command("COMMAND foo");
237        Added perlwrap.pm to contain perl code to be compiled into
238                the binary.  This is transformed into perlwrap.c by
239                encapsulate.pl.
240        Renamed readconfig.c to perlconfig.c and changed variables accordingly.

286        Added the 'toggle-oneline' command
287        The 'o' key is bound to 'toggle-oneline'

331        The message object now uses a list of attributes internally, in
332          prep. for supporting new messaging protocols

362          will be executed when new messages arive that match the
363          alert_filter
364        added the 'term' command which takes the 'raise' and 'deiconify'
365          options.  It assumes xterm for now.
366        only 'make distclean' will nuke core and ~ files now
367        fixes to owl_function_do_newmsgproc from Stephen
368        converted functions.c to new code style, which I'm giving a shot

372        configure.in: see if des_ecb_encrypt is already prototyped.
373        configure.in: minor changes to work with new autoconf without needing acconfig.h.
374        configure.in: find the install program.
375        configure.in: test for use_default_colors since some versions of
376          solaris don't have it, so we can at least compile something
377          vaguely working there.
378        keypress.c: ifdefs for keys not defined on at least some solarises.
379        owl.c: don't call use_default_colors if we don't have it
380        readconfig.c: added *commented out* code to try to find a
381          system-default owlconf if the user doesn't have one.  Have to
382          ponder if I want this
383        zcrypt.c: don't prototype des_ecb_encrypt if there is a prototype in
384          des.h.
385        zcrypt.c: include owl.h so we get the configure-generated config.h
386        Change to codelist.pl to deal with new code style
387        Remove some ancient stuff from zcrypt.c
388        General cleanup to Makefile.in

404          WORK yet
405        Removed a bit of faim code that allowed commands to be executed.
406        The 'B' key is now bound to 'alist'
407        Added the 'startup' and 'unstartup' commands

421       
4221.2.7
423        Outgoing messages now go through the config for formatting
424        Zaway now makes an outgoing message, instead of an admin message
425        The 'zlocate' command can now handle multiple users
426        The simple user format for "To:" is in effect again
427        Prettyed up the zwrite line for using 'reply' on a zaway
428        Added a workaround for a libzephyr bug that caused zwrites to fail
429          if zephyrs were sent just before and just after renewing tickets
430        Fixed a memory bug in getsubs
431        Added receive support for zcrypt messages
432        Added the 'zcrypt' variable which controls whether or not zcrypt

441        Added search, '/' and '?' to basic help.
442        Will attempt to keep the current message as close as possible
443             to the previous current message after an expunge.
444        "set <variable>" and "unset <variable>" now work for boolean variables.

453        Patch to fix memory bug in replying to CC messages
454        If we're on Athena and have static krb (or other) libraries, use
455          them
456        Added "athstatic" program to the release, which handles the above
457        Cast to an int for isspace, to make gcc -Wall quiet
458        Added 'zlist' and 'l' to basic help.
459

462             'tty' variable before setting the zlocation
463        There is now a 'zlist' command that acts like 'znol -l'

465        Fixed memory leak uninitialzed memory read in fmtext
466        viewwin will now say "End" instead of "More" when at the end
467        Added a debugging message indicating the result of topmsg
468          calculations

470        The built-in personal filter is updated to do so
471        Fixed a bug in moving the pointer after an expunge
472        Fixed up the normal scrolling code.  Now it should always
473          land on a message, but it's still not optimal.
474        Added the variable 'smartstrip' which will strip kerberos
475          instances out for the 'reply' command.
476        Added -R/usr/athena/lib to the build for Athena
477        Started updating the intro document
478        Small changes to help / about
479        The 'subscribe' and 'unsubscribe' commands (and their aliases) now
480          update .zephyr.subs by default.  If either is given the '-t'
481          (for "temporary") option the .zephyr.subs will not be updated
482        Turned off beeping for hitting the top or bottom of the list of
483          messages
484        Made daemon.webzephyr a special case for smartstrip
485        Added 'out' as a default filter for outgoing messages
486       
4871.2.3
488        Added filters "ping", "auto" and "login" by default.
489        Added "body" as a valid field to match on in a filter.
490        Temporary fix to bug where C-SPACE would cause the key handler to
491             lock up.
492        Messages now have a direciton (in, out or none).  Filters can
493             match on this direction
494        Outbound messages are no longer type 'admin' but are of the
495             appropriate message type (i.e. 'zephyr') and are direction
496             'out'.
497        Smartnarrow now works on outgoing messages
498        'info' updated to show more information for admin and outgoing
499             messages
500        Renamed pretty_sender to short_zuser and renamed long_sender to
501             long_zuser
502        Moved zsig generation to the zwrite object
503        Print the zsig used for outgoing messages
504        The tty variable now controls the zephyr location tty name
505       
5061.2.2
507        Added the 'search' command.
508        '/' is a keybinding for 'search'
509        '?' is a keybinding for 'search -r'
510        Fixed stristr, which was completely broken
511        renamed owl_fmtext_ztext_stylestrip to owl_function_ztext_styletsrip
512             and put it in functions.c
513        Attempts to stay near the current message when switching views.
514             When switching from an empty view to one we've previously
515             been in, the new current message position will attempt
516             to be close to the current position from the last
517             time we visited that view.
518        Fixed bug in readconfig.c that prevented building under perl 5.005.
519        Switched "C-x C-x" to only "startcommand quit"
520        'getsubs' prints closer to the order you sub in.
521        Modified the behavior of last so that "> >" will clear the screen.
522        The new behavior of last is:
523              Moves the pointer to the last message in the view.
524              If we are already at the last message in the view,
525              blanks the screen and moves just past the end of the view
526              so that new messages will appear starting at the top
527              of the screen.
528        Fixed a typo in the help for smartzpunt.
529        Fixed functions to handle curmsg being past the end of the view.
530
5311.2.1
532        New framework for command handling.
533        New framework for keymap handling.
534        Added commands for everything that is bound
535             to a key (do 'show commands' to get the full list).
536        Added 'multi' and '(' commands to allow multiple commands
537             to be specified on a line.             
538        Added user keybindings with bindkey command.
539        Added command aliases (eg, "alias foo bar").
540        Added undelete command that parallels the delete command.
541        Added additional options to delete command.
542        The reply command now takes arguments.
543        Added 'edit:insert-text' command.
544        Added 'show zpunts' to show active punt filters.
545        Added 'show variable <name>' and 'show variables'.
546        Added 'show command <name>' and 'show commands'.
547        Added 'show keymap <name>' and 'show keymaps'.
548        Added 'M-u' to undelete all messages in current view.
549        Fixed dotsend so that the zephyr will still send if there
550             is whitespace after the dot but not on the same line.
551             This should resolve an issue where dotsend wouldn't work
552             if you'd gone up and edited a zephyr.
553        Bug in page down fixed
554        C-t will transpose characters
555        Fix the scrolling bug where we would sometimes fail to scroll
556             the screen down, leaving the current message off
557             the bottom of the screen.
558        Refixed 'login or login' typo in help
559        Fixed M-u description
560        Removed 'first' and 'last' from basic command help
561        Added M-N to basic key help
562        Added M-D, M-u to basic key help
563        Fixed a quoting problem in configure.in
564        Changed top of help to use 'show' instead of M-x
565        Fixed a bug in the summary field for user-created aliases
566        Added "reply zaway" which sends a zaway response to the current msg.
567        Added "edit:delete-prev-word" command and bound M-BACKSPACE to it.
568        Some buffer overruns fixed
569        Variables now have a summary and a long description.
570                Only the summary is shown with help.
571                The long description is shown with "show variable foo".
572        Added a 'scrollmode' variable which determines how the screen
573             will scroll as the cursor moves.  The default behaves
574             identically to previous versions of owl.
575             The following modes are supported:
576             normal      - This is the owl default.  Scrolling happens
577                           when it needs to, and an attempt is made to
578                           keep the current message roughly near
579                           the middle of the screen.  (default)
580             top         - The current message will always be the
581                           the top message displayed.
582             neartop     - The current message will be one down
583                           from the top message displayed,
584                           where possible.
585             center      - An attempt is made to keep the current
586                           message near the center of the screen.
587             paged       - The top message displayed only changes
588                           when user moves the cursor to the top
589                           or bottom of the screen.  When it moves,
590                           the screen will be paged up or down and
591                           the cursor will be near the top or
592                           the bottom.
593             pagedcenter - The top message displayed only changes
594                           when user moves the cursor to the top
595                           or bottom of the screen.  When it moves,
596                           the screen will be paged up or down and
597                           the cursor will be near the center.
598        Added owl_sprintf which returns the formatted string, or NULL.
599                The caller must free this string.
600                This will allocate enough memory and thus
601                avoid potential some buffer overrun situations.
602        Simple implementation of 'zwrite -m' (doesn't yet log an outgoing
603                message as having been sent.)
604        The "Not logged in or subscribing to messages" error
605                now includes the name of the recipient.
606        The "disable-ctrl-d" variable may also be set to "middle"
607                which will result in ctrl-d only sending at the
608                end of the message.  This is now the default.
609                This also added a command "editmulti:done-or-delete".
610        Fixed a bug in the "reply -e" command.
611        Always clear the command buffer before executing the command.
612                (So that interactive commands can sanely do start-command.)
613        Fixed preservation of e->dotsend across owl_editwin_clear().
614        Added history for multiline edit windows (eg, for zephyr composition).
615                The M-n and M-p keys will cycle through the history ring.
616                In particular, it is now possible to edit the command line
617                of a zephyr being composed:  C-c it and restart it
618                and then M-p to get the aborted composition back.
619        Added owl::send_zwrite(command, message) to the perl glue
620                to allow for the direct sending of multi-line messages.
621                For example:  owl::send_zwrite("-c foo -i bar", "hello");
622        Changed owl_fmtext_print_plain to return an alloc'd string to
623                avoid buffer overrun risks.
624        Added owl::ztext_stylestrip("...") function to perlglue
625                 which returns the ztext with formatting stripped out.
626        Added colorztext variable which can be used to disable @color()
627                 strings arriving in messages after it is set.
628                 (Currently, changing its value won't reformat messages).
629        Outgoing zephyr logging now obeys the logpath variable.
630        The '~' character in logpath and classlogpath now gets
631                 replaced with the user's home directory.
632        Added simple implementation of smartnarrow-to-admin that
633                 creates a "type-admin" autofilter.
634                 This was done mostly so that M-C-n and M-C-p do something
635                 sane on admin messages.
636        Added opera to the allowed options to the webbrowser variable.
637        Fixed some buffer overruns in the "reply" command.
638        When repying to "all" on a message that begins with "CC:" (eg, sent
639                 with "zwrite -C", the reply line will be constructed
640                 from the sender and the usernames on the CC: line
641                 of the message being replied to.
642        There is no such thing as C-R, so left C-r as it is but added:
643                 M-r --- edit reply to all
644                 M-R --- edit reply to sender
645        Added RCS Id strings to all files.
646        'show keymaps' shows details of all keymaps after summary list.
647        Added --no-move option to delete command.
648                In particular, delete-and-always-move-down may now
649                be implemented with
650                '( delete --no-move ; next --skip-deleted )'.
651        Folded the nextmsg and prevmsg commands and functions together into
652                one command which takes arguments.
653                Added '--filter <name>' option (eg, for next_personal),
654                '--skip-deleted' option, and
655                '--last-if-none'/'--first-if-none' options.
656                Help updated accordingly. 
657                In particular, the 'personal' filter is now used
658                for 'next personal'. 
659                Added --smart-filter and --smart-filter-instance options
660                to the next and prev commands.
661        Updated examples/owlconf.erik with the above.
662        Made owl_function_fast*filt return a string and not do the
663                narrowing, to make it more general.
664        Added a smartfilter command that creates a filter
665                based on the current message and returns the name
666                of the filter.
667        Added M-C-n and M-C-p keybindings to "move to next message
668                matching current" and "move to previous message
669                matching current"
670        Added variables edit:maxfillcols and edit:maxwrapcols which
671                will limit how wide editing paragraphs may get before
672                they get wrapped.  This is a max and may be narrower
673                depending on the current size of the window.
674                If 0, the max is unlimited.  Default is 70 columns for
675                edit:maxfillcols and unlimited for edit:maxwrapcols.
676        Added smartzpunt command with key binding of "C-x k".
677                This starts a zpunt command filled in with
678                the proposed zpunt.
679        Fixed a memory reference bug in delete and undelete commands.
680        Added support for perl to call directly back into owl.
681        Changed the implementation of owl::command("...") to immediately
682                call back into owl.  This allows perl to get the return
683                value of strings returned by owl commands.
684        Added the getview command which returns the name of the current
685                view's filter. 
686        Added the getvar command which returns the value of a variable.
687        Added an example to examples/owlconf.erik which uses TAB to
688                narrow and restore the view. 
689        Added an example to examples/owlconf.erik which uses M-c to
690                color messages matching the current one green.
691        Integrated change to fix problem with popup blinking on new zephyrs.
692        C-l and resizes will now refresh an open viewwin (eg, help).
693        Updated doc/code.txt to include info about filters, commands,
694                contexts, and keybindings.
695        Exec commands cleaned up to not have buffer-size limitations
696                and to not mess up spaces.  exec also returns a string
697                of the output now.
698        Integrated changes from 1.1.3, and added docs for "zlocate -d"
699                and new show commands.
700        Show with arguments produces help on show.
701        Fix a bug in readconfig caught by efence (where we'd try to read before
702                the beginning of a string if it was empty).
703        The perl command doesn't do makemsg directly, but instead
704             returns the string and it will get printed if it
705             was run interactively.
706       
7071.1.3
708        'show subs' and 'show subscriptions' are now the same as 'getsubs'
709        zlocate now takes an optional -d argument
710        'show terminal' / 'show term'
711        '>' / last doesn't set the last message at the top of the screen now

715        changed the bug address in the startup message
716        can now do 'show status'

718        'status' / 'show status' includes the owl version number now
719        'show terminal' includes whether the terminal can change colors
720        fixed off by one bugs in paging / scrolling viewwin
721        don't downcase the sender when getting the log name for personals
722        support @owl::fields as well as @fields
723        downcase class/inst filter names in auto filters
724
7251.1.2
726        Fixed memory mishandling bug
727        Fixed bug in redfining the filter attached to the current view
728        M-n will narrow to message, instance on non-personal, class
729             MESSAGE messages
730        M-N behavies like M-n except that on class messages it narrows
731            to class and instance
732        line wrap earlier, to account for tabbing
733        fixed typo in help
734        'status' command now displays info on terminal color support

742        added the 'colorview' command
743        added the 'show colors' command
744        users who don't have a .zephyr.subs get a simpler format for
745          incoming messages
746        If colors are available 'show filters' will show a filter in the
747          color associated with it.
748        Added the zpunt and zunpunt commands
749        Lines in the subs file starting with '-' are zpunted
750        Include login/logout messages in auto user filters
751        'V' changes to the home view ('all' by default)
752       
7531.1.1
754        Fixed perl, aperl, and pperl commands to deal with quoting
755              and spaces in a saner manner.
756        Removed all owl_get_* methods for booleans and switched
757              cases where they were used to owl_is_*
758        Changes to owlconf.erik to use some new features.
759        Increased the size of the help buffer (as it
760              was overflowing and truncating the help message).
761        Variables prefixed with a _ are not shown in help
762              or by printallvars (and prefixed Not Yet Implemented
763              variables with this).
764        Fix typo in help

824        Added owl::id to perl namespace with message id

828              a string not ending in a newline
829        Added 'X' keybinding which expunges and then switches to

848              and the owl_dict type.
849              These include regression tests.
850        Overhaul/rewrite of variable handling.  Variables are now managed
851              in an owl_vardict (in g.vars) which contains a dictionary
852              of owl_variable's.  Each owl_variable has dispatch functions
853              for validating values, setting it and getting it,
854              and for setting it to and from string values.
855              The variable.c file contains the list of variables.
856              Stubs for the owl_global_<varname>_get functions and friends
857              are generated from variable.c by stubgen.pl.
858              The help.c messages for variables now calls into variable.c
859              so all information about most variables is in one place.

865              to running owl_function_printallvars.
866        debug is now a variable that can be turned on and off.

869        Changed owl_function_makemsg and owl_function_debugmsg
870               to use varargs (ie, so they can now take a format
871               string with args).
872        Don't allow " and \ characters in URLs with the "w" command.
873        Removed lots of build warnings.

882              be appended to the sepbar.  This allows the configfile
883              to put information about pings and logins into
884              the sepbar.  (It may be worth also providing a variable
885              which enables this by default, but for now this allows
886              for experimenting with what works well.)
887        Added doc/code.txt which gives a brief overview of the code.
888        Added tags makefile rule and added TAGS to distclean rule.
