   1 TODO list for agedu
   2 ===================
   3
   4 Before it's non-embarrassingly releasable:
   5
   6  - cross-Unix portability:
   7     + use autoconf
   8        * configure use of stat64
   9        * configure use of /proc/net/tcp
  10        * configure use of /dev/random
  11        * configure use of Linux syscall magic replacing readdir
  12           + later glibcs have fdopendir, hooray! So we can use that
  13             too, if it's available and O_NOATIME is too.
  14        * what do we do elsewhere about _GNU_SOURCE?
  15
  16  - tweak the short options. I think dump files should be a
  17    second-class feature in general, so that --dump and --load should
  18    be represented by capital options. That leaves -d free to be
  19    --depth, which I think is more generally useful.
  20     * while I'm tweaking the options list, "[all modes]" ought to
  21       say "[most modes]", due to --scan-dump.
  22
  23  - New mode: --remove, to destroy the data file. Handy for
  24    totally self-contained usage: "-s . -w -R".
  25
  26  - man page, --version.
  27
  28 Future possibilities:
  29
  30  - IPv6 support in the HTTP server
  31     * of course, Linux magic auth can still work in this context; we
  32       merely have to be prepared to open one of /proc/net/tcp or
  33       /proc/net/tcp6 as appropriate.
  34
  35  - run-time configuration in the HTTP server
  36     * I think this probably works by having a configuration form, or
  37       a link pointing to one, somewhere on the report page. If you
  38       want to reconfigure anything, you fill in and submit the form;
  39       the web server receives HTTP GET with parameters and a
  40       referer, adjusts its internal configuration, and returns an
  41       HTTP redirect back to the referring page - which it then
  42       re-renders in accordance with the change.
  43     * All the same options should have their starting states
  44       configurable on the command line too.
  45
  46  - curses-ish equivalent of the web output
  47     + try using xterm 256-colour mode. Can (n)curses handle that? If
  48       not, try doing it manually.
  49     + I think my current best idea is to bypass ncurses and go
  50       straight to terminfo: generate lines of attribute-interleaved
  51       text and display them, so we only really need the sequences
  52       "go here and display stuff", "scroll up", "scroll down".
  53     + Infrastructure work before doing any of this would be to split
  54       html.c into two: one part to prepare an abstract data
  55       structure describing an HTML-like report (in particular, all
  56       the index lookups, percentage calculation, vector arithmetic
  57       and line sorting), and another part to generate the literal
  58       HTML. Then the former can be reused to produce very similar
  59       reports in coloured plain text.
  60
  61  - http://msdn.microsoft.com/en-us/library/ms724290.aspx suggest
  62    modern Windowses support atime-equivalents, so a Windows port is
  63    possible in principle.
  64     + For a full Windows port, would need to modify the current
  65       structure a lot, to abstract away (at least) memory-mapping of
  66       files, details of disk scan procedure, networking for httpd.
  67       Unclear what the right UI would be on Windows, too;
  68       command-line exactly as now might be considered just a
  69       _little_ unfriendly. Or perhaps not.
  70     + Alternatively, a much easier approach would be to write a
  71       Windows version of just the --scan-dump mode, which does a
  72       filesystem scan via the Windows API and generates a valid
  73       agedu dump file on standard output. Then one would simply feed
  74       that over the network connection of one's choice to the rest
  75       of agedu running on Unix as usual.
