Release Notes for Apcupsd 3.14.x Apcupsd 3.14.x is the latest STABLE release, containing many bug fixes and new features over the previous 3.12.x stable series. Users of all previous versions are encouraged to upgrade. IF YOU USE THE OLD STYLE MASTER/SLAVE NETWORKING MODE, BE SURE TO READ THE 3.14.0 RELEASE NOTES BELOW. 3.14.14 -- 31 May 2016 BUG FIXES * win32: Fix missing DLLs when installing only apctray * Fixes for socket error handling. Resolves apcaccess crash when connection fails as well as several other theoretical issues. * MODBUS/USB error handling (COMMLOST) improvements for faulty USB links * Fix hiddev binding when usbfs is mounted on /dev/bus/usb instead of /proc/bus/usb. This is necessary for switching between MODBUS/USB and USB/HID on Linux. * Update GPLv2 text and FSF address to match current versions from FSF. * Various fixes for potential issues suggested by Coverity Scan * MacOS X port support for El Capitan System Integrity Protection (SIP) aka "rootless" * Fix shutdown failure on Windows when UPSNAME includes spaces * Fix building bsd-usb driver (This was broken when modbus-usb support was added.) FEATURES * Add status display for output current as well as apparent power 3.14.13 -- 02 February 2015 NEW FEATURES * MODBUS USB support Previous releases supported MODBUS serial (RS232). This release adds support for MODBUS over USB. This protocol is preferable to the normal USB HID driver because it offers access to more UPS data readouts and controls. The only configuration file change needed versus MODBUS serial is to change UPSCABLE to usb and use an empty DEVICE setting. See the MODBUS section of the apcupsd manual for more details. * Support for Apple Notification Center on Mac OS X (replaces Growl) * Apple install packages and binaries are signed with an Apple Developer key for compatibility with Gate Keeper * Windows USB driver has been updated with additional USB identifiers to support future APC products. BUG FIXES * Use launchd for startup on Mac OS X as the old Startup Items mechanism is no longer supported in 10.10 and above * Fix apcaccess on ARM systems where char is unsigned by default * Fix several potential issues identified by Coverity static analysis * Numerous other fixes and improvements all over the code, many of them submitted by users...Thank you! MISC * Windows port now builds with the same configure and make system as the other targets, no need to maintain a special hardcoded Makefile. * Many cleanups to the Windows port codebase * Prebuilt binaries for Mac OS X no longer support PowerPC systems or Mac OS X 10.4 and older 3.14.12 -- 29 March 2014 (Maintenance Release) NEW FEATURES * apcaccess and apcupsd status format updates to ease parsing by scripts * UPS name is included in subject line of emails in default scripts * Default event scripts pull SYSADMIN and APCUPSD_MAIL definitions from a common config file so they can easily be configured in one place BUG FIXES * Fix issue with certain Back-UPS USB models repeatedly cycling power on/off after killpower is issued * Fix display of battery level during MODBUS calibration * Fix apctest EEPROM setting on various models * Close and reopen serial port during extended COMMLOST in apcsmart driver (helps recover connection when USB serial port dongles are reconnected) * Avoid probing non-APC USB devices as it can cause lockups * Fix issue with service failing to start on Windows during boot with USB UPS * Fix bogus lock file error when config file error forces early termination * Fix MODBUS NOMOUTV reading for voltages other than 120VAC * Fix LOADPCT (CI_LOAD) on MODBUS driver * Fix issue with net driver not reporting MODEL value 3.14.11 -- 31 January 2014 (Maintenance Release) NEW FEATURES * MODBUS protocol support Over the summer, APC publicly released documentation[1] on a new UPS control and monitoring protocol, loosely referred to as MODBUS (after the historic industrial control protocol it is based on). The new protocol operates over RS232 serial lines as well as USB connections and is intended to supplement APC's proprietary Microlink protocol. Microlink is not going away, but APC has realized that third parties require access to UPS status and control information. Rather than publicly open Microlink, they have created another protocol to operate along side it. Many existing Microlink UPSes can be upgraded to support MODBUS via a firmware update. See [2]. Certain older models are not upgradeable. APC support will be your best contact for determining if your UPS supports a MODBUS upgrade the information linked below does not make it clear. For now, apcupsd supports MODBUS over RS232 serial only. It DOES NOT yet support MODBUS over USB. See the apcupsd manual[3] for information on setting up apcupsd.conf for MODBUS UPSes. [1] http://www.apc.com/whitepaper/?an=176 [2] http://www.schneider-electric.us/support/index?page=content&country=ITB&lang=EN&id=FA164737 [3] http://www.apcupsd.com/manual/manual.html * Windows USB driver is now digitally signed thanks to Jernej Simoncic <jernej's-sflist@eternallybored.org> 3.14.10 -- 13 September 2011 (Maintenance Release) BUG FIXES * Fix missing status and spurrious incorrect status on newer BackUPS CS models using USB interface. * USB compatibility fixes for Mac OS X Lion * USB driver support for newer Microlink models on Mac OS X Lion and Windows * Ignore transitions to battery due to calibration (possible if user initiates calibration, then exits apctest and starts apcupsd before calibration completes. * Fix truncation of long UPS model names such as "Smart-UPS RT 5000 XL" * Fix MODEL vs. APCMODEL confusion. Remove APCMODEL and rename old MODEL aka 'mode' to DRIVER. 3.14.9 -- 22 July 2011 (Maintenance Release) NEW FEATURES * SNMP enhancements: - Autodetection of MIB and community if they are not specified in apcupsd.conf - Support for RFC1628 MIB - Support for MGE MIB (Contributed by Lars Taeuber <taeuber@bbaw.de>) * Windows USB support for 64-bit platforms * USB support for latest APC models such as SMT* and SMX* series - No support for Microlink, but basic USB interface should be detected and provide status now. * When using the generic USB driver (Windows, OS X, newer FreeBSD) DEVICE string in apcupsd.conf can be set as serial number of UPS to monitor. This is useful in order to "lock" apcupsd to a specific UPS if you have more than one connected to the server. * Ed Dondlinger's Windows email scripts are included in the Win32 install package now. Documentation includes information on how to hook them in. BUG FIXES * general: Rework signal handling to eliminate crashes and hangs. * general: Fix issue of overwriting pid file even when we failed to acquire the lock file * snmp: Add workaround for FreeBSD libsupc++.a issue (FreeBSD PR #99702) This will allow snmplite driver to compile/link on FreeBSD 5.x. * usb: Automatically use generic_usb driver on FreeBSD 8.0 and newer. FreeBSD USB API was changed in 8.0, so from now on we will use libusb. * usb: Add support for DALARM * usb: Fix BATTV and MANDATE on certain newer APC models * win32: Honor INSTDIR specified on command line via /D * win32: When running uninstaller in silent mode, always remove config and events files without prompting. * win32: When logging events, convert LOG_CRIT to a WARNING rather than an ERROR since apcupsd uses it for power events which aren't really daemon errors. 3.14.8 -- 16 January 2010 (Maintenance Release) NEW FEATURES * Mac OS X version of apctray (apcagent) for monitoring apcupsd instances. Same feature set as apctray on Windows (monitor multiple instances, get detailed status and events logs). Popup notifications delivered via Growl, if available. * Major update to win32 version of apctray. Includes many visual and usability improvements to match OS X version. * apctest now supports battery calibration and self-test interval control on USB models. Many thanks to James Belleau <james@belleau.net> for contributing these features. * New SNMP driver that does not require libsnmp.so, thus eliminating issues with not finding the library during shutdown when /usr has been unmounted. The new driver is the default for 'UPSTYPE snmp'. The old driver is still available as "UPSTYPE netsnmp" if needed. BUG FIXES * Add missing NOMINV, NOMOUTV, and NOMPOWER to net clients * Fix missing WALL in apccontrol (debian bug #546019) http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=546019 * Change all time/date strings to simplified ISO format: "YYYY-MM-DD HH:MM:SS +/-UTC" * Fix battery voltage readout on "Back-UPS 500 FW: 6.3.I USB FW: c1" * Remove obsolete image files from source tree * Fix issues with popup.exe running when it shouldn't and sometimes hanging and/or generating an "Interactive Services Dialog Detected" error. * Use /kill switch from the installer to shut down running instances of apcupsd and apctray. This will provide more reliable termination on Vista/Win7. * Update apctest to use 'Q' to exit any menu instead of a number that is always changing. Contributed by James Belleau <jpbelleau@gmail.com> * apctest: Fix compiler warnings. Contributed by Andy O'Shaughnessy <andrewjoshaughnessy@gmail.com> 3.14.7 -- 31 July 2009 (Maintenance Release) NEW FEATURES * Multimon CGI programs are included with the Windows binary package BUG FIXES * Windows COM ports above COM9 now work without user needing to manually add \\.\ UNC prefix in apcupsd.conf * Fix configure script not noticing when C++ compiler is missing * Fix for battery date (BATTDAT) displaying invalid values on USB models * Fix version reporting in cgi and examples * Misc documentation fixes for typos, etc. 3.14.6 -- 16 May 2009 (Maintenance Release) NEW FEATURES * Major updates to the User Manual. Rewritten battery maintenance section courtesy of Trevor Roydhouse <trev@sentry.org>. Many other updates including the SmartUPS protocol and OS support sections. Furthermore, the manual is now formatted in reStructuredText (http://docutils.sourceforge.net/rst.html) and as a result is very easy to update. (The only down side is the multi-page HTML version is no longer available; the HTML version is all on a single page.) * New manpages for apcupsd, apcupsd.conf, apctest, apcaccess, and apccontrol. Many thanks to Trevor Roydhouse <trev@sentry.org> for the hard work! * Support for QNX. Tested on QNX 6.3.2. Contributed by Mikhail Gruzdev <michail.gruzdev@gmail.com> * Add support for turning the UPS off completely. This complements existing hibernate (aka killpower) functionality. Turn-off is implemented for apcsmart and USB drivers, subject to support for the relevant commands in the UPS itself. Contributed by Keith Campbell <campbell@econnectix.com>. BUG FIXES * apcsmart: Deadlock fixes during comms failures. Contributed by Keith Campbell <campbell@econnectix.com> * linux-usb: Fix out-of-bounds array access. Contributed by David Fries <david@fries.net> * Fix build with gcc-4.4. Contributed by Michal Hlavinka <mhlavink@redhat.com> * apcsmart: Fix crash during process shutdown (SIGTERM). Contributed by Andrey Sharandakov <ash.ashway@gmail.com> * Several other minor fixes and improvements. See ChangeLog for details. 3.14.5 -- 26 October 2008 (Maintenance Release) BUG FIXES * docs: Document the /refresh switch for apctray. * apctest: Do not create pid file. There is little reason for it since apctest is a command-line tool, not a daemon. Plus nothing ever deletes the file so it interferes with apcupsd operation. * gapcmon: Network connect timeout fix. * Fix a few unsafe uses of sprintf and strcat. * Makefile: Fix cgi build on OpenBSD. libgd on OpenBSD requires X_LIBS for libfreetype and libfontconfig. * gapcmon: Iconify fixes for KDE * Fix LOWBATT glitch handling bug that could cause us to act on a LOWBATT signal immediately instead of waiting for the debounce time. * apctray: Improve multiple instance behavior for /add, /del, and /kill on modern platforms (Win2K and newer). * Support shutting down apcupsd instances running in other sessions (such as terminal services or remote desktop sessions). * Makefile: 'make install' fixes for first install on RedHat/SuSE. * docs: PCNET minimum password length is 15 chars, default username is 'apc', no known way to change the username. * Makefile: Fix dependency build errors on Darwin and other platforms. ('echo -n' is not portable; use 'tr' to strip newline instead) * RPMs: Automatically restart apcupsd when upgrading 3.14.4 -- 18 May 2008 (Maintenance Release) MAJOR CHANGES * Build system rewrite: All Makefiles have been rewritten from scratch. Improvements include reliable dependencies, support for parallel make, elimination of Makefile.in -> Makefile conversion, consistent use of DESTDIR during 'make install', and pretty-printed output during builds. NEW BUILD SYSTEM NOTES - GNU make is required. The configure script checks for this and tells you how to invokve it (on some platforms it is 'gmake' instead of 'make'). - Output during build is pretty-printed by default. To see more details, use 'make VERBOSE=1' for output similar to the old build system. For even more verbosity, use 'make VERBOSE=2'. - Parallel builds work well. If you have a multiprocessor (or multicore) system, try 'make -j<number-of-processors>' for the fastest possible build. * Built-in version of libgd for multimon cgi has been removed. The version previously included in apcupsd was old and likely had security issues. It is safer to use libgd from the target system. Therefore, your system must provide libgd if you choose to build cgi now. Generally this is easy to achieve by installing a vendor-supplied package. * Removal of NLS support: The NLS code was terribly bit-rotted with many non-internationalized messages and almost every translated message was incorrect. At this point the maintenance burden of keeping NLS support building was deemed too high considering the small benefit it was able to provide. * Powerflute has been disabled. It has been broken for the last several releases because it relied on an untrushworthy source of UPS status (rawupsstats) which was itself removed. Powerflute could be converted to use the standard NIS status mechanism and its source code remains in the tree in case someone has the desire to contribute this code. NEW FEATURES * Add POLLTIME directive to control UPS polling interval. This directive specifies the number of seconds to delay between polling the UPS for status. Previously, NETTIME allowed this to be adjusted for network connections only (snmp, pcnet, nis-net). POLLTIME configures the delay for all connection types. NETTIME is accepted as a synonym for compatibility with old config files. BUG FIXES * gapcmon: Corrected the use of NOMPOWER and the calc of current usage amount. Thanks to James Scott Jr <skoona@verizon.net>. * Add a heuristic to fix up incorrect NOMINV or NOMOUTV. Some UPSes (RS 500) report decivolts instead of volts. Reported by Kirill S. Bychkov <yason@linklevel.net>. * Various build fixes on Solaris and OpenSolaris. Thanks to James Dean <jgmdean@gmail.com> for loaning me an ssh login on his OpenSolaris box. * Fix hal policy file syntax. For some reason this blatantly incorrect file actually works on RHEL5 (hal-0.5.8). Thanks to Andrew Telford <a.telford@ieee.org> for correcting it. * Fix gapcmon build on OpenBSD. * Fix BSD USB driver build. * Fix default NIS port on Debian. Debian is now using the standard NIS port, 3551. Contributed by imacat <imacat@mail.imacat.idv.tw> 3.14.3 -- 20 January 2008 (Maintenance Release) NEW FEATURES * A HAL policy file is automatically installed on Linux systems to disable the hald-addon-hid-ups module which conflicts with apcupsd's control of USB UPSes. The file is automatically removed when apcupsd is uninstalled. BUG FIXES * Add support for Nominal Power (aka Configured Active Power) reading. Credit to Lars Randers <lars@nstec.dk> for most of the code. * Add units to NOMINV, NOMOUTV, and NOMBATTV stats. * Eliminate "warning: deprecated conversion from string constant to 'char*'" warnings emitted from gcc-4.2.1 (earlier versions with -Wwrite-strings). Contributed by Steve Yarmie <tribhuvanji@gmail.com>. * Fix killpower and eeprom settings bug on USB models introduced when INPUT reports were prioritized over FEATURE reports. * Fix bugs that could cause NIS-net driver to get stuck waiting for comms to be restored instead of shutting down. 3.14.2 -- 15 September 2007 (Maintenance Release) NEW FEATURES * Tray icon support on Vista. Vista does not allow background services to interact with the user's desktop, so winapcupsd's built-in tray icon did not work. * Tray icon is now a standalone application "apctray" which is capable of monitoring multiple Apcupsd instances via Apcupsd's NIS. Any Apcupsd running NIS can be monitored. By default the icon monitors a single apcupsd at See command line options below for adding additional monitors. * Tray icon can be installed individually (disable other packages in the installer) for users who want to use the icon only. * Apctray command line options: apctray.exe - No parameters: Start any instances listed in registry. If no instances in reg, start a default instance monitoring the local machine ( apctray.exe /host foo /port 3551 /add - Add a monitor for the given host and port. apctray.exe /host foo /port 3551 /del - Remove the given monitor. apctray.exe /del - Remove all monitors. apctray.exe /install - Configure apctray to start automatically. apctray.exe /remove - Do not start automatically. apctray.exe /kill - Shut down apctray BUG FIXES * The win32 portions of winapcupsd have been almost entirely rewritten. The code is cleaner (mostly) and lots of unused baggage has been removed. * USB fix for BackUPS LCD series. This fix carries a risk of breaking other models, but test results are positive so far. * Fix linux-usb device detection bug when multiple hiddev nodes are present. Fixes Fedora Bugzilla #245864: <https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=245864> * Fix SNMP port selection when using SNMP driver * Add workaround for broken BackUPS Pro model that returns certain reports encoded in ASCII. Based on a patch from David Fries <David@Fries.net>. * apcsmart: Wait 20 seconds before declaring COMMLOST. This is necessary when using a smart serial cable on an UPS with an SNMP monitoring card installed. The SNMP card appears to disrupt serial comms for several seconds when interesting events are in progress. * Documentation updates: Fix up udev info for modern Linux distros. Update Windows section for apctray. * Don't leak unnecessary descriptors to child when execing apccontrol. * Fix bug with multi-threaded net_open() calls. net_open() was using a global buffer for the destination address. Yikes! Bug manifestied itself in apctray with multiple monitors occasionally (and timing-dependently) pointing to the wrong UPS. * Correct multimon.conf humidity monitoring. Problem fixed by Patrick Frei. Reference: https://bugzilla.novell.com/show_bug.cgi?id=199834 * Fix race between attach_ups() and detach_ups() which could result in the UPSINFO structure being freed prematurely. Thanks to James Abbott <j.abbott@imperial.ac.uk> for running many tests to help me find this bug. * Remove dependency on libc++ (again). Must use gcc as linker when using libsupc++ since g++ automatically links against full libc++. 3.14.1 -- 04 May 2007 (Maintenance Release) NEW FEATURES * MacOS X GUI installer * PCNET driver supports remote shutdown request from UPS web interface BUG FIXES * (win32) Detect when balloon tips have been disabled via a group policy and fall back on the standard popup message box. * (win32) Fix typo: "%sbindir\%popup" -> "%sbindir%\popup" in apccontrol.bat Discovered by Stefan.Hegnauer@elektrobit.com. * (all) Fix potential NIS client lockup when server disappears. Many thanks to Jan Ceuleers <jan.ceuleers@computer.org> for reporting the problem and gathering data to track down the cause. * (apctest) Fix link error after configuring with --disable-apcsmart. * (doc) Document how to force ugen binding on NetBSD 4.x. Contributed by Curt Sampson <cjs@starling-software.com>. * (apctest) Fix crash when displaying EEPROM values more than once. Contributed by Ivaylo Haratcherev <I.J.Haratcherev@tudelft.nl>. * Increase self-test timeout to 40 seconds to accomodate the RS 800. Contributed by Lars Randers <lars@nstec.dk>. * (linux-usb) Rewrite device opening logic to be more reliable. See ChangeLog for details. * (apcupsd) Do not attempt to cancel shutdowns. 3.14.0 -- 09 February 2007 (Feature Release) NEW FEATURES * USB support for 3 new platforms: - Windows (Win98SE, WinME, Win2000, Win2003 Server, WinXP) - Mac OS X (Darwin) - Solaris 10 (x86 and SPARC) Please see the Apcupsd manual for details on USB configuration for the new platforms. * Native Windows port The winapcupsd port has been completely rewritten to use native Win32 libraries (based on MinGW32). It no longer relies on a Cygwin translation layer, thus improving compatibility and performance. * PowerChute Network Shutdown driver Apcupsd now supports the PowerChute Network Shutdown protocol (PCNET) offered by the AP9617 family of smart slot modules. This protocol is much lighter-weight than SNMP and offers better security. Please see the Apcupsd manual for details on PCNET configuration. * GAPCMON GUI monitoring tool Apcupsd is now packaged with the GAPCMON GUI monitoring application thanks to James Scott, Jr. This is a Gnome/GTK based application which integrates into most desktop panels (not just Gnome). It monitors one or more Apcupsd instances using Apcupsd's NIS networking server. The status of each UPS is shown with a icon similar to the Win32 tray icon in winapcupsd. Enable building of gapcmon at compile time via --enable-gapcmon or install the apcupsd-gapcmon RPM. * Unreliable MASTER/SLAVE networking mode is removed Yes, this is a feature. The old MASTER/SLAVE mode for shutting down multiple servers from one UPS has historically been unreliable and prone to loss of communications or lockups. Apcupsd has long had a replacement networking mode using the NIS server (NIS stands for Network Information Server, and has nothing to do with Sun's NIS/YP protocol). The NIS net mode is very reliable and has none of the lockup bugs that have plagued MASTER/SLAVE mode. In 3.14.x, MASTER/SLAVE mode has been removed and the associated configuration directives are now obsolete. Please see the Apcupsd manual for a very simple NIS networking configuration to replace MASTER/SLAVE. * New configuration directives to set paths at runtime Several new (optional) configuration directives have been added to allow overriding compiled-in paths at runtime. The directives are: - SCRIPTDIR (sets location of apccontrol and event scripts) - PWRFAILDIR (sets location where powerfail file will be written) - NOLOGINDIR (set location where nologin file will be written) These directives can be used to rearrange the Apcupsd installation after compiling, or to run multiple Apcupsd instances on the same machine without compiling separate copies. See the Apcupsd manual for details on these new directives.
