2014 November 23 2.3 Remove trailing whitespace. Remove deprecated /usr/X11R6/include directory from CFLAGS. Merge clean and clean-all targets in Makefile. Respect DESTDIR variable in Makefile, e.g., for package creation. Fix -Wunused-result and -Wunused-but-set-variable compiler warnings. 2014 August 18 2.2 Remove VCS files from source. Manpage installation location now follows Filesystem Hierarchy Standards. Rename acpi to wmacpi-cli to avoid conflict with the acpi binary that ships with acpiclient (http://sourceforge.net/projects/acpiclient). Allow additional flags to be appended to CFLAGS and/or LDFLAGS during build. Now maintained by the Window Maker Developers Team . Git repository: git clone git://repo.or.cz/dockapps.git 2009 August 10 2.2rc5 Small Makefile fix to allow compiling on newer GCCs, supplied Michael Shigorin of ALT Linux. 2008 November 14 2.2rc4 Change the way that we sleep/wait for activity, to use select rather than a fixed-length sleep, supplied by Julien Blache of Debian: Hi, The attached patch for wmacpi makes it use select() instead of sleeping. It also adjusts the timeout of the select() call depending on the blink & scroll options. If scrolling is not activated, there's no reason to wake up 10x/sec. If blinking is activated, waking up once per second is enough. If blinking is not activated, then we can wake up just to update the data and we're fine. With scrolling and blinking disabled, this saves a number of wakeups and helps battery life. Unfortunately there's another source of wakeups that's probably due to libdockapp that still makes 6 wakeups/seconds (in another thread it seems). With this patch wmacpi makes a best effort to match the sample rate set by the user, but that's hardly an issue I think. I haven't released this patch yet in Debian, so if you like it and want to roll out a release, feel free :) Otherwise I'll add it to the package soon. Thanks, JB. 2008 March 18 2.2rc3 Some fixes for the sysfs interface support, supplied by jblache@debian.org: > Okay, I finally found time to make a new release including this > patch - 2.2rc2. It's up on my website now. I don't remember sending you the updated patch, as it turned out that you can have different attributes in sysfs depending on what the battery reports. The current version is attached. Thanks, JB. 2008 March 14 2.2rc2 Support for the sysfs interface that became mandatory with kernel 2.6.24 (patch supplied by jblache@debian.org). A number of graphics fixes also from jblache@debian.org. Removed support for hardware reported critical battery status. 2007 July 14 2.2rc1 Major changes to command line handling and to the way we use libdockapp, courtesy of Patrice Dumas. This should hopefully fix several long-standing bugs with non-wmaker window managers (in particular Debian bugs #280495 and 293546). Updated to support newer kernels that no longer support /proc/acpi/info - thanks to Samuel Ortiz. Fixed a longstanding issue with redrawing - thanks to Vito Caputo. This version changes a number of command line options (little used ones, but they're still incompatible changes) due to the libdockapp work. In particular, -w becomes -x, -v becomes -V (and takes an argument rather than being repeated), and -V becomes -v (thanks to libdockapp grabbing -h, -v and -w for itself). Also, long options are now supported for everything in wmacpi (but not acpi, since it doesn't use libdockapp for command line parsing). 2007 January 10 2.2a1 Added a patch from Patrice Dumas to support newer versions of libdockapp. Updated email address in AUTHORS and manpages. 2005 February 2 2.1 Finalised libdockapp-0.5.0 port - no changes from 2.1rc1. 2005 Jan 5 2.1rc1 Typo fix in the manpage. Ported to libdockapp-0.5.0 - all this needed was changing the type of the dockapp width and height to unsigned short. 2004 October 24 2.0 Upped version number to 2.0. Small typo fixes. wmacpi 2.0 goes gold . . . 2004 September 28 2.0rc1 Added support for switching to capacity mode automatically, on detecting dodgy reports from the battery. Added support for capacity mode on charging, with automatic enabling as per discharging. Various cleanups. Hopefully last release before the final 2.0. 2004 August 18 1.99r7 Implemented the libdockapp port - this seems to close Debian bug #227819, but it hasn't received sufficient testing. Implemented a capacity mode for calculating time remaining (as opposed to the normal current rate mode) - this mode samples the remaining capacity of the battery and notes the time at which it was sampled, and uses a history of samples to estimate the rate of drain on the battery. From there it calculates a value for time remaining. Also, various cleanups have gone in: * a reworking of the scrolling code * generic battery number support (rather than just using two pixmaps, one for b1 and one for b2) * stopped the battery glyph from blinking when running on AC 2004 July 19 1.99r6 Fix for Debian bug #250792 - the parser for the acpi files was too stupid to deal with error conditions. I've now added some basic checking to make it handle the error that caused the bug report, but I'll need to add more later. 2004 April 23 1.99r5 Collected fixes for the collected fixes below . . . * Manpage fixes, to reflect the reality of the current code. * Code cleanups, to make a few things more sensible. Most notably, the interface for setting the samplerate has changed so that it's no longer inverted and illogical - you now say how many times you want to sample per minute. * Fixed an issue with initialisation - I'd moved the power_init() call below the options parsing code, without dealing with the -m option properly. The end result was that if you told it to monitor a battery number, it would fail saying the battery didn't exist. I moved the check for this out of the options parsing and after the power_init() call. * Fixed a leaking file descriptor in init_ac_adapters. * Implemented a way to handle changing batteries - reinitialise the battery info periodically. I don't know of a better way to do that, since we'd have to do all that parsing anyway to find out if it had changed . . . libdockapp is waiting, but I think that's the only change left without more bug repots . . . 2004 April 15 1.99r4 Collected fixes for various small issues. * Fixed a problem with placement of the window when using the click to place mode - turned out to be a sizehints problem. * Some fixes to the manpage. * Reenabled the CLI build by default - the Debian patches can handle disabling it themselves. * Added a way to disable the scrolling message, since some users find this annoying. I've left the big changes that are needed (like using libdockapp, in the hope that it'll solve the docking problems) until later, so that I can get these smaller fixes out. Hopefully soon . . . 2004 January 12 1.99r3 . . . and a fix for a fix that didn't fix it . . . 2004 January 12 1.99r2 Some cleanups and bugfixes found by the wonderful Debian users. It's finally in testing! 2003 November 23 1.99 Finally claimed the wmacpi name as my own . . . Renamed wmacpi-ng and acpi-ng, renamed the header files, fixed up the makefile. For the Debian package, also made compilation of the command line tool optional, defaulting to not building it. This is because after the renaming, my acpi clashes with the acpi package that's already in Debian. The command line functionality is now accessible via the -w option to wmacpi. This is wmacpi 1.99, so that I can have a release packaged and in Debian before going to 2.0, so that any bugs that are left can be found by all the extra users. 2003 September 26 0.99 Fix the last of the old wmacpi code oddities (specifically, the APMInfo struct, which was a completely inappropriate name given we no longer deal with APM, and because of the various code refactoring). I think this is probably as good as I can make it without getting more feedback and the like, so I'm going to make this version 0.99, preliminary to either wmacpi-ng 1.0 or wmacpi 2.0 (depending which direction I go with that). 2003 September 23 0.92 Fix a few more bugs, and include an option to allow the user to specify how often to sample the ACPI data - some BIOSes disable all interrupts while reading from the battery, which apparently causes some interactivity issues. I have no idea why reading once every three seconds (which is our default), but there've been some complaints. Also fixed acpi-ng to properly handle the -a option. 2003 August 6 0.91 Fix a problem I'm seeing with docking the app - if the window name is set to "acpi" rather than "apm" it doesn't dock . . . 2003 July 16 0.90 Make the time display show '--:--' instead of '00:00' when the time remaining is 0 - I think this is reasonable, since it'll only get into this state when the present rate value is 0. This only happens when the battery is fully charged and neither discharging or charging, or when the battery is completely drained. In any of these states the time remaining is of very little interest, so we don't lose anything. We also get to handle the (sadly, very common) case where the ACPI subsystem doesn't report sane values for the things we depend on. 2003 July 11 0.50a2 Make the time display show nothing (as opposed to 00:00) when the time remaining is unknown, as requested by Emma Jane Hogbin. Respect the critical level specified on the command line, and add a new message to differentiate between the command line critical level and the critical state reported by the battery. Speed up the message scrolling, so that there isn't quite such a painful delay between repeats. Also, up the speed when the battery is low, more when it's critical, and scroll continuously when it's hardware critical. Finally, add support for disabling the blinking power and battery glyphs from the command line, as requested by Sebastian Henschel. We still blink the battery glyph when the battery reports hardware critical level - I think that's worth being a bit annoying about. Also, added an acpi-ng manpage. 2003 July 11 0.50a1 Properly fix the AC adapter issue - it's not much use adding the infrastructure and then forgetting to fix the code that uses it. Fix the time disiplay so that it doesn't try to display values greater than 99:59, since the display area won't fit anything beyond that. 2003 July 10 0.50a Bugfixes, to handle two problems: the case where something like the present rate or some such is "unknown" (reported initially by Emma Jane Hogbin, and where the AC adapter is called something other than "AC" (reported by Sebastian Henschel). This an 'a' release because I can't test these myself . . . 2003 July 6 0.50 Finally got rid of that annoying button - that space now contains a 'B 1' or 'B 2' (only those two at present, since I'm too lazy to fix it so that the number is generic. It should work fine for anyone who doesn't have a freakish system with more than two batteries . . .) A few more code cleanups. 2003 July 1 0.19 libacpi cleanups and reworking - we now handle the charging battery case properly, it seems. Also, some attempts to make error printing a bit cleaner; still a long way to go on that, though . . . 2003 June 24 0.15 Removed process_plugin_timer(), since it was doing nothing useful at all . . . 2003 June 23 0.14 Removed libapm.c - wmacpi-ng is specifically for ACPI, with no APM support. 2003 June 23 0.13 Some more code cleanups, designed to move libacpi to more of a library than something built into wmacpi-ng. This is useful with the seperate programs, though at present it's not used much. 2003 June 21 0.12 Added a command line tool, acpi-ng to query battery status from the command line. 2003 May 30 0.11 Implemented multiple battery support, and averaging of the samples in an attempt to even out the jumpiness of the timer. 2003 May 30 0.10 More major code cleanups: in particular the handling of the power panel and the message has been cleaned up so that it's actually sane and clean. Next step from here is to actually implement handling of multiple batteries, so that if there's a fully charge second battery available it reports the correct time remaining (based on the present rate of power consumption and the sum of the two battery's remaining capacities). 2003 May 29 0.3 Some major reworking of the internals, to help fix the handling of multiple batteries and such things. 2003 May 26 0.2a Code cleanups to fix various problems with corner cases. 2003 May 26 0.2 Added support for multiple batteries: I took the simple route of displaying only one battery per instance - to do more I'd need to hack with the display code, and I'm not ready for that yet. Added a -m option to specify the battery number to monitor. 2003 May 26 0.1 Changed package completely, to support the new ACPI code as of 2.4.21-rc2. Since this code hasn't been touched in more than a year, I figure I might as well have a go at hacking on it . . . -- Simon Fowler, 2002 Feb 17 1.34 Updated ACPI statistics gathering code for the latest ACPI patch from Intel. Now uses/checks for subsystem version 20020214+. Redone the version check a little bit. 2001 Apr 29 1.33 Little fix to ACPI version check so that I don't have to make a new version each time a new kernel comes out 2001 Mar 24 1.32 Split ACPI and APM portions in different source files Added power_init() function - handles checking subsystem presence, version, etc. Enumerates batteries in ACPI implementation ACPI: Beginnings of multiple battery support - not fully implemented ACPI: Get the battery ID from /proc/acpi/battery instead of hard-coding it in - also helps with multi battery stuff Added some stupid command line help Added -c option to set critical battery alarm level. Defaults to 10 percent, and added -b option to make noise when this critical level is reached APM: Updated for critical alarm stuff Made a 20 color "low" quality pixmap for machines running 8bit displays Updated README with some stuff, made separate INSTALL file 2001 Mar 13 1.31 Update for intel ACPI release version 20010313 Minor updates for new /proc layout 2001 Mar 07 1.3 Update for intel ACPI release verion 20010302 Proc format changed a little bit, so updates were necessary. Added a check for specific acpi subsystem version - since each new version seems to have a new interface, better be safe than sorry :) As usual, please test and report to me. This ONLY works with linux acpica 20010302. Download this version from http://developer.intel.com/technology/iapc/acpi/downloads.htm - it's a patch against 2.4.2 2001 Feb 28 1.21 Finally read through the ACPI specification. Hah, they had all my questions answered :) Thus, Confirmed remaining percentage formula (correct) Now calculate "time remaining" according to the spec formula Removed "battery load" hack since we now have "time remaining" Fixed bug in display_percentage (10% didn't display right) Released version 1.21 2001 Feb 23 1.2 Added support for ACPI. This is very untested, and not very clean. This has been tested on machines with only ONE battery, and only with kernel 2.4.2 (that's where ACPI started to work for me) Added some hackery to do with ACPI. Check README. Released 1.2 2001 Jan 16 1.1 Fixed all the stuff so that wmapm works as advertised: Fixed dumb bug where after charging was done new message didn't scroll. Added support for fucked APM bioses that display stuff wrong. (See README to learn how to enable it. Obviously, it's disabled by default) Reorganized apminfo structure and got rid of redundancy. Reorganized acquire_apm_info. All APM data is processed there. Fixed display_state to do the Right Thing. Fixed red blinking button to actually blink on critical battery, and to stop when it isn't critical anymore. I don't think it ever worked right in 1.0. Created ChangeLog. Updated README. Released 1.1.
