Technical notes on my code submission of 11 Nov 99
                        Kern Sibbald

General:
- I worked mainly on the cgi programs. 
- For all the files that I changed, you will see that they
  are fully tabbed now (i.e. where ever a tab could be
  inserted, it is). This generated a bit more changes
  than might otherwise be the case since many spaces were
  replaced by tabs. This is in keeping with the new coding
  standards.
- For the new files that I created, I created them in
  my own indenting style. This needs to be reviewed and
  possibly I will need to reindent them.

Changes submitted this submission:
- Added the cgi directory to the Makefile.in.  To build
  the cgi programs, you must explictly type "make cgi"
  To install them, you must "make install-cgi". 
- Temporary kludge to the ./configure script to configure
  the cgi-bin directory, use:

      ./configure -datadir=/home/httpd/cgi-bin

- Updated apcaccess to print all the new information.
- apcaccess attaches to the shared memory with read-only
  access. Consequently, you no longer need to be root
  to run apcaccess.
- apcaction.c, updated a couple of messages to be more
  explicit, and only log "Allowing logins" if logins were
  actually stopped.
- I added permissions to the creation of the shared memory area
  to the create_shmarea() call. The current value is 0644 (as
  before), but this probably should be put in a header file or
  as a configuration parameter.
- I added permissions to the attach_semaphore() call. This allows
  the user to call it in read_only mode.

How to get the new cgi code running:
1. Add the datadir option to your ./configure as described
   above to configure your installation path.  
   If you want to do this manually, cd to the cgi directory,
   insure that the three .cgi programs are built, then
   copy these three programs to your cgi bin. 

2. Do the following:
   
   ./configure -datadir=...
   make
   make install
   make cgi
   make install-cgi

3. Restart your apcupsd daemon                     
   
4. Start the apcnetd daemon (not done automatically so
   for the moment you will have to do it after every
   reboot).

   ./apcnetd

5. Edit /etc/apcupsd/hosts.conf to add your hosts to be
   monitored. You must do this.

6. Optionally edit /etc/apcupsd/multimon.conf to change the default
   multimon display. The list of available keywords can be found
   in cgi/upsfetch.c and multimon.h.

7. Execute the multimon program from your browser with something like:

   http://127.0.0.1/cgi-bin/multimon.cgi

8. Good luck

   
Work to complete (this seems to get longer each submission!):
- Documentation.
- Automatic conversion of old apcupsd.config files
  to the new format?
- Eliminate the rest of the printfs().
- Examine all configuration messages, and eliminate all
 "Someone will have to explain this to me" messages.
- Check and double check killpwr changes.
- Correct problems pointed out by Riccardo in integrating
  my submission.
- Complete writing of status logging.
- Add the full status display to the cgi program (same
  as currently printed by "apcaccess status"
- Remove remaining traces of old log file. 
- Cleanup error_abort/printf inconsistencies in cgi code.
- Possibly retab new cgi/net server code
- Make apcnetd capable of being called from inetd
- Add more commands (individual variables) to apcnetd
- Make fetch_data() be called automatically from 
  getvardata().
- Put in new capabilities code.
- Start capabilities codes from 0 instead of 1.
- Add additional STATUS output.
- Create new line for status bits but in English
- Fix name of unknown() and change comments in subroutine
  save_dumb_status() ...
- Make non-available STATUS information print N/A
- Update CGI programs to understand N/A
- Expand Last UPS Self Test field in cgi program
- Produce a RPM for RedHat
- The TCP port for apcnetd should be configurable.
- Probably apcnetd should be started at the same time
  as apcupsd. Or perhaps a configuration parameter should
  be added to have apcupsd start it.
- Change translo and transhi to be use new mnemonics
  lowxfer and highxfer.
- Remember date and time when apcupsd started.
- Accumlate time on batteries and number of transfers
  to batteries. Perhaps save history in file so that the
  info can be recovered if apcupsd restarts.
- Save last 5 major events and pass them in STATUS file.
