1.1     ! misho       1: 
        !             2: Hi everyone, 
        !             3: 
        !             4: This is the "todo" file for mtr. I just realized that some people
        !             5: might think that this is all in MY queue to implement. That is not
        !             6: true: This is the "for everybody" todo list. Feel free to pick a
        !             7: "project" and implement something off this list.
        !             8: 
        !             9: Students: Feel free to take up one of these as a programming exercise
        !            10: for one of your courses.
        !            11: 
        !            12: Everybody: If you want to start on something, contact me first, so
        !            13: that the effort isn't wasted by someone who finishes just a tad
        !            14: earlier. I'll happily provide "coaching" to anyone who wants to
        !            15: implement something on this list. That way we get the design of
        !            16: these things the way I like them. This should result in a better
        !            17: maintainable mtr.
        !            18: 
        !            19: Oh, Feel free to provide suggestions for this list. 
        !            20: 
        !            21:

        !            24: ----------------------------------------------------------------------

        !            26: 
        !            27: - Stuff to implement:
        !            28: 
        !            29:   - Allow mtr to log the return packets, for later analysis.
        !            30:     Done: 0.25 . Todo: allow the user interface(s) to work while
        !            31:     still logging to a file. Write a "logfile displaying" mode to
        !            32:     mtr.
        !            33: 
        !            34:   - Request timestamping at the remote site.
        !            35:        Andreas Fasbender has an algorithm that will allow us to 
        !            36:        convert these measurements into one-way measurements, not just
        !            37:        round-trip.
        !            38: 
        !            39:   - allow "keyboard navigation" in the GTK version. 
        !            40: 
        !            41:   - Keep all packets and make the "best" and "worst" columns show the
        !            42:     xx-th percentile....
        !            43: 
        !            44:   - Can the reports generated also include any secondary servers?  In 
        !            45:     the interactive mode, any new servers that are found in the 
        !            46:     traceroute are added to the list, but it seems to only include 
        !            47:     one set of servers when using the -r option.  
        !            48: 
        !            49:   - Being able to expand the "column width" of the hosts listed would 
        !            50:     be nice, too.
        !            51: 
        !            52: 
        !            53: - Bugs to fix?
        !            54: 
        !            55:   - Do something useful if host couldn't be resolved. 
        !            56:        -- Done. 
        !            57: 
        !            58:   - Revert to curses mode even if DISPLAY is set, but a problem
        !            59:     prevents us from running in X11 mode.
        !            60:        -->  The problem is that gtk_init simply calls exit for us if
        !            61:             it finds a problem. Tricky! Suggestions welcome. 
        !            62:        --> Call "gtk_check_init" when available. (i.e. new enough
        !            63:            (1.2?) GTK version).
        !            64: 
        !            65: - Nice to have:
        !            66: 
        !            67:   - stop sending packets when a new host is getting entered. 
        !            68: 
        !            69:   - Show state ("looking up host") while doing the DNS lookup for a new
        !            70:     host.
        !            71: 
        !            72:   - to have a choice of icmp, tcp, and udp pings. -- Matt Martini
        !            73: 
        !            74:   - Autoconf 2.13 has a neat function that can be used to find the 
        !            75:     res_init function: 
        !            76: 
        !            77:           AC_SEARCH_LIBS(res_init, bind resolv, ,
        !            78:              AC_MSG_ERROR(No resolver library found))
        !            79: 
        !            80:     At the moment (march 1999) autoconf 2.13 is still too new to require 
        !            81:     everyone to upgrade. About a year from now we can put this in....
        !            82: 
        !            83:   - Implement rfc2317 mechanism to do reverse lookups for networks that
        !            84:     have DNS delegations on non-octet boundaries. -- Daniel Bergstrom
        !            85:     (noa@melody.se)
        !            86: 
        !            87:   - The longer MTR runs, the less meaningful the packet loss
        !            88:     statistic. Or more meaningful, depending on your point of view.
        !            89:     Perhaps MTR should use a circular buffer of some configurable
        !            90:     number of results, and calculate the loss against that. -- Jacob Elder
        !            91: 
        !            92:   - It would be nice if the window size wasn't fixed. If I'm only 5
        !            93:     hops from the host I'm monitoring, MTR wastes a lot of screen real
        !            94:     estate. -- Jacob Elder
        !            95: 
        !            96:   - Colors in the curses version. -- Amix
        !            97: 
        !            98:   - If we run a mtr to monitor a connection it would be nice if the time at
        !            99:     which mtr was started is print somewhere. -- Sebastian Ganschow
        !           100: 
        !           101: 
        !           102: 
        !           103: ------------------------------------------------------------------------
        !           104: 
        !           105: Things that shouldn't be on the TODO list because they're done. ;-)
        !           106: 
        !           107:   - Allow a toggle between hostname/IP number display. (for example a 
        !           108:     click on the hostname could revert to ip number display in gtk version.
        !           109:     curses: "n" key toggles hostnames/ipnumbers?)
        !           110: 
        !           111:   - Allow mtr to also send larger packets. 
        !           112:        This will enable us to get a feel for the speed of the links
        !           113:        we're traversing. (Van Jacobson was working on this His tool
        !           114:        was slow, mtr will rock with this feature.... :-)
        !           115:        (Anybody have the statistics experience to tell me how
        !           116:        to do the data analysis?)
        !           117:        -- DONE. Thanks to Olav Kvittem ...
        !           118: 
        !           119:   - The "don't probe all hosts at once" strategy can be improved a bit.
        !           120:     It should not probe more than 10 unknown hosts, but the counter need
        !           121:     not be reset at the start of the "round". This way if you probe
        !           122:     slowly (relative to the RTT time to the end host), it can probe
        !           123:     all hosts in the first "round". 
        !           124:        -- DONE.
        !           125: 
        !           126:   - Read environment variable "MTR_DEFAULTS" as a commandline before
        !           127:     parsing the commandline.  -- DONE. (ok it's MTR_OPTIONS.)
