New in owfs 2.8 P5 (Jan 7, 2011)

  • Organize memory and pages a little better in code for consistency

New in owfs 2.8 P4 (Dec 2, 2010)

  • module/owlib/src/c/ow_write.c: Added some debug messages to write code.

New in owfs 2.8 P2 (Aug 30, 2010)

  • Fix an indent problem in the pyowfs program. (Joshua J Kugler)
  • Fix an error scanning through /structure diretories (specifically triggered by updatedb and FC family). (Eloy Paris)
  • Add better output for the /structure in owhttpd
  • Fix variable types in /structure

  • Clean up of caching:
  • Singleton values are cached on read, deleted on write

  • Arrays handled all together are cached only as .ALL or .BYTE, never as singletons. On singleton write, the cache is used for the other values, then deleted.
  • Mixed array types are handled as the most recent access, with the alternative cache method deleted.

New in owfs 2.8 P1 (Aug 19, 2010)

  • Fix owpython bug (problem with infinite loop in newest python versions) Joshua J. Kugler
  • Coordinate variations in LINK and LINK-HUB-E adapters (with the assistance of Achim Hennies)

  • Fixed problem with "/alarm" directories. Reported and tested by Michael Markstaller
  • Added the --debug command line argument which is the equivalent of "--foreground --error_level=9" (I get tired of typing that every time).
  • Fix an architexture-dependent crash in the owserver ping loop (solved by Leon)

New in owfs 2.8 P0 (Aug 2, 2010)

  • W1 (the linux kernel module now called "wire") that handles several types of 1wire bus masters is now supported as a surrogate bus master.
  • Includes usb, i2c and some architecture-specific gpio (OMAP and ARM)
  • Bus masters are added and removed dynamically based on netlink messages from the kernel
  • Need Kernel version 2.6.31+ for best performance
  • Use "--w1" on the command line
  • Linux-specific
  • Must be run as root.
  • using -usb will supercede the w1 usb (since the ds2490.ko module is unloaded)
  • This meas that there are now 3 means of dynamically adding bus masters:
  • uscan (via a libusb scanning loop)
  • w1 (via the kernel module and netlink messages)
  • zero (via Avahi or Bonjour for owservers)
  • New ./configure option for bus traffic display
  • configure --enable-owtraffic
  • Byte data from the various bus (i2c, usb, serial, network) are sent to stderr
  • Minor fix for libownet read not including a NULL at the end of the string.

New in owfs 2.7 P39 (Jul 19, 2010)

  • Major addition is the usb scanning funtion.
  • Command line option -uscan or --usb_scan or --usb_scan=10
  • Every time interval (default 10 seconds) the OWFS program will scan the
  • USB bus for a new DS9490R adapter and add it to the list of bus masters.
  • Even the case where no USB devices exist at startup will be handled, the
  • program will scan and wait.

New in owfs 2.7 P38 (Jun 7, 2010)

  • Mostly bug fixes, including a memory error(in HA5) and MUTEX macro name collision. Cleaned up some USB handling in anticipation of Libusb1.0 support.

New in owfs 2.7 P37 (May 10, 2010)

  • Mostly bug fixes, including a memory error(in HA5) and MUTEX macro name collision. Cleaned up some USB handling in anticipation of Libusb1.0 support.

  • Include support from Egil Kvaleberg for the
  • A. B1-R1-A Hobby Boards Barometer
  • B. S3-R1-A Hobby Boards Solar Radiation sensor
  • Change threading model to allow owserver and owhttpd to run under OSX
  • Relax alias constraints in owserver
  • Alias files can be specified for only the server and will propagate back to clients.

New in owfs 2.7 P35 (Apr 13, 2010)

  • Minor release. Fix for some caching problems, and an improved owserver
  • lock/ping mechanism.
  • No longer requires semaphore waiting or fancy timestamps.

New in owfs 2.7 p20 (Apr 6, 2009)

  • Fixes bugs in DS2406 and memory leak with some write instructions. Fixed man pages.
  • Added the mock adapter -- a fake variant that can be written to and remembers written values.
  • Added fully setable fake device names.
  • Andrey-b found bug in independent setting of DS2406 PIO channels. We were using sensed value rather than set value for other channel.
