30 October 2003

General:
Changes submitted this submission:
30Oct03
- Integrated Alexander Schremmer's stdout fix for Windows --
keeps debug printout from being sent to the serial port.
28Oct03
- Bob Kuo found a bug that caused a seg fault, which was due
to my code that walked off the end of a table in linux-usb.c
03Oct03 Released here
- Move the old manual to old_documents and commit the
new docbook manual to the CVS. Don't include the web
html directory.
28Sep03
- Test net slave mode. It works fine. I made it behave more
like a slave, so it shows the last time it contacted
the master.
- Add MASTER name to status output if device is a slave.
- Display last master update if device is a net slave.
- Add 10 sec delay before calling apcupsd --killpower it is
needed for USB killpower to work right. Why????
- Save old apccontrol when installing a new one.
- Replace old UPS_SET() with set_ups() in a number of places.
27Sep03
- Implement autodetect of USB port if no DEVICE given.
14Sep03
- After the upgrade to RH9 with the new autoconf, quite a
few things broke. As far as I can tell, it is because autoconf
set top_srcdir to ., and since apcupsd exects top_srcdir to be
absolute, lots of things broke. Fixed by editing all the
Makefiles and switching to topdir.
- Had to disable autoheader since it wipes out config.h.in
10Sep03
- Made pthreads default -- lots of problems converting to new
autoconf -- it deleted my config.h.in file!
01Sep03
- Fixed bad file descriptor in SO_KEEPALIVE for slave (reported
by Derek Battams.
- Added informative subject to email onbattery, ... (suggested
by a user, thanks -- sorry I forgot who).
- #ifdef off IP6 code in inet_pton for platforms that do not have it.
06Aug03
- Added the -s "$MSG" to each of the script files (mainsback, ...)
as suggested by Nicholas Robinson.
- The dependencies were not being correctly generated, so
simplified the code.
- Added install: to the include Makefile.in. Lack of it
caused problems on OpenBSD.
- Changed LINEVOLT to MAINS in apcstatus.c to fix a problem
reported by David Walser of CGI reporting zero volts.
- Tried to clarify the difference between the net and
the master/slave drivers in the doc.
05Aug03
- Because of the complaints about the master/slave code, I finally
got around to testing it, and it was seriously broken in more
than one way. It seems to be working now.
- Started adding new set_ups() instead of UPS_SET().
- Adding the SIGCHLD broke quite a lot of calls in the master/slave
code. This will probably also show up elsewhere.
04Aug03
- Tested the net driver, it seems to work perfectly fine. I
did add a grace period of 4 seconds with comm loss on batteries
before the shutdown is done.
- A number of changes to the manual.
- Clean up the net driver to be compatible with C++ for building
on Windows.
- Ensure that we don't get stuck in a waitpid loop after calling
apccontrol. Hopefully this will fix the 100% CPU usage on Win32
after a power condition.
18Jul03
- Reissue accept() immediately if interrupted rather than waiting.
15Jul03
- In attempting to build the .cgi files on Windows, I realized that
the gd1.2 code was no longer in the distribution. Although some
people were worried about the gif patent (I wasn't) it has now
expired, so I see no reason why not to distribute the code as
we always have. For the purists, it appears that the version you
have on your system (png) will be used in preference to the local
gd code.
- I backed out the 12July SNMP changes since they probably only
work for 3 phase and I don't have the libraries to test compile
or the card to test.
12Jul03
- Modify snmp driver to use upsPhaseOutputPercentPower instead of
upsAdvOutputLoad as requested by ivac@gnjilux.srk.fer.hr.
08Jul03
- As reported by Brandon Applegate, the net driver was not
clearing old flags after a power failure. In fact, it was
really screwed up -- it always or'ed in the new bits thus
keeping any old status, and blasting out any local bits.
Fixed hopefully.
- Made a new set of defines for setting/clearing/testing ups
Status bits that is much easier to read.
- Added Sergey Vlasov's second USB kernel patch to the examples
directory. The two patches can be found in:
linux-2.4.20-killpower.patch
linux-2.4.20-USB-reject.patch
The emails are also in that directory.
- As suggested by Sergey for the 2.5 kernel, I have #ifdefed
out the call to HIDIOCGREPORT in the int_write routine used
for killpower.
07Jul03
- Lots of updates to the document.
- Fixed a slave crash in master/slave mode. It was a missing setup_device,
and was diagnosed and reported by Christian Schacht -- many thanks.
30May03
- Made non-existent header files non-fatal and added #ifdef
around sys/socket.h so it will compile on IRIX.
- Add Scott's latest apcupsd.conf with the hid-ups program code
(actually I had done this some time ago ...).
- Start a ReleaseNotes file
20May03
- Fixed a typo error (mine) that prevented Scott from building
rpms. Strange, it worked for me????
19May03
- More DESTDIR cleanup for building non-root rpms.
18May03
- Add DESTDIR everywhere so we can build rpms non-root
- Additional documentation
- Add Scott's new apcupsd.spec
06May03
- On Hilary Jones suggestion, I fixed the ./configure message that
is printed when no libgd is found to direct the user to the
main source.
01May03
- Add Sergey Vlasov's kernel patch to the examples directory,
and it replaces the previous patch.
This patch now solves the killpower problem on Linux USB.
<apcupsd-source>/examples/linux-2.4.20-alt-apc_usb_ups.patch
notes are in: linux-usb-patch-email.txt
22Apr03
- Add TTY mode to apctest to communicated directly with UPS.
- Apply patch to linux-usb.c in killpower supplied by
Sergey Vlasov (thanks!).
19Apr03
- Eliminate pow() function in linux-usb.c so that -lm is not needed.
14Apr03
- Add automatic detection of socklen_t
11Apr03
- I received a kernel patch from Sergey Vlasov that fixes
the killpower problem on CS UPSes. apcupsd can now shutdown
these devices! I've removed some debug code that was in
the killpower routine and is not needed or used.
I have put the kernel patch in:
<apcupsd-source>/examples/linux-2.4.20-alt-hidups.patch
05Apr03
- When the Win32 version starts as a service, delete the
NOLOGIN and PWRFAIL files to prevent later confusion.
Thanks to Allen Crawford for pointing this out.
29Mar03
- Modify all Win32 program so that only windowed programs
(apcupsd, popup) have the -mwindows flags. The others do not.
- Tweak apctest.c a bit -- add EEPROM programming (still a bit
kludgy), but at least it can be done.
21Mar03
- Lots of clean ups for Cygwin stuff. Events now work, and exit.
- Clean up a few undefined symbols in building with everything on.
- Eliminate pid and serial port lock file on Win32 systems.
10Mar03
- Modify init script to use daemon so that STDIN/OUT, ... are
detached from the terminal and pointed to the log file. This
prevents remotely logged in users who start apcupsd from being
unable to log out.
06Mar03
- Made some mindor modifications to configure.in and aclocal.m4 to
make consistent use of double quotes in test statements in
response to problems with make install reported by Andrew Surratt.
- Thanks to Richard Schwaninger for finding and submitting a patch to
the tcp-wrappers code that prevented it from working because of an
invalid name. Fixed.
05Mar03
- Thanks to Andrew Reid for pointing out that the child reaping code
should be clearing the pid slot if a -1 is returned. The pid table
was filling up on his system due to killed children. Fixed
21Feb03
- A bug report against the Mandrake version of apcupsd indicates that
apcupsd is not releasing /dev/console. I've moved the close() of
STDIN so that it is always executed to prevent this possibility.
12Feb03
- Implement very crude first cut of EEPROM programming in apctest.
Set battery date, set UPS name, and print EEPROM values should
work.
