2010-06-16 Niall Power - <niall.power@oracle.com>
	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Remove accidental clobbering of tempSchedule list so
	  that non-archived backups can be expired as per normal
	  schedule retention rules. Opensolaris defect #16280

2010-06-04 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/time_slider/applet.py:
	  Register menu callback in Note class instantiation to
	  avoid multiple registration of same callback.

2010-05-24 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/time_slider/setupgui.py:
	  Fix minor function spelling typo

2010-05-24 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/glade/time-slider-setup.glade:
	  Replace GtkFileChooser combo widget with standard
	  GtkComboBox

	* usr/share/time-slider/lib/time_slider/applet.py:
	  User path_tol_volume() from util library instead of
	  private copy

	* usr/share/time-slider/lib/time_slider/setupgui.py:
	  Replace standard GtkFileChooser logic with custom combo
	  box implementation that is more tailored towards selecting
	  a backup device rather than a generic path. Is able to 
	  handle an offline/unmounted previously configured backup
	  device gracefully (impossible with stock widget). Doesn't
	  show meaningless shortcuts like Home, Documents, etc. either
	  Cleanup of code, renamed variables to use camel case and 
	  made unnecessarily public class variables private.
	  Changed order of target validation tests to check if the
	  device supports posix style links before checking if it's
	  empty. Means user doesn't have to delete everything on a
	  PCFS/FAT32 device only then to find out it's still unsuitable.

	* usr/share/time-slider/lib/time_slider/util.py: Move previously
	  private function path_to_volume(path) here so it can be shared.

2010-05-14 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/time_slider/applet.py:
	  Use icon list hinted by gio.Volume instead of hardcoded
	  harddisk icon when possible when displaying notifications.
	  Makes icon more context specific to type of backup device.

2010-05-14 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/time_slider/applet.py:
	  Determine volume name of rsync target if available and
	  display that instead of the raw mount point in 
	  notifications. More user friendly.

2010-05-14 Erwann Chenede - <erwann.chenede@sun.com>

	* usr/share/time-slider/glade/time-slider-delete.glade:
	  Added Type combobox
	* usr/share/time-slider/lib/plugin/pluginsmf.py:
	  fix import to call this class from a non standard 
	  location
	* usr/share/time-slider/lib/time_slider/deletegui.py:
	  implemented rsync backup visualization and deletion
	* usr/share/time-slider/lib/time_slider/zfs.py: 
	  renamed member function destroy_snapshot to destroy 
	  to reflect allow polymorphic call in deletegui.py
	  as the list of backup to delete can now be snapshots
	  or rsync backups.
	* usr/share/time-slider/lib/time_slider/timesliderd.py:
	  propagated member function destroy name change.

2010-05-14 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Fix list ValueError in list_pending_snapshots() caused
	  when rsync plugin is enabled but no fileystems are 
	  selected for backup. Check that zfs returns something
	  more than a blank in such cases.

2010-05-14 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/glade/time-slider-setup.glade:
	  Fix resizing issue that prevented list view from expanding
	  to occupy all extra space when window gets vertically
	  extended.

2010-05-14 Niall Power - <niall.power@oracle.com>

	* etc/dbus-1/system.d/time-slider.conf:
	  Add service and policy definitions for TimSlider.config
	  service.

	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Deal with backup device being mounted under variable
	  removable media mount points if not found in it's expected
	  location. Find and validate alternate mount points.

	* usr/share/time-slider/lib/time_slider/applet.py:
	  Refactored to allow more modular notification management.
	  Improved rsync device monitoring by implementing both gio.File
	  and gio.Volume monitors so we can track mounting/unmounting of
	  static mounts like nfs/zfs and variable mount points for 
	  hotpluggable devices. Validate rsync target is correct using
	  SMF configuration key. Listen to TimeSlider.Config D-Bus events
	  and refresh configuration when D-Bus notification is received.
	  Add menu item to enable launching of setup GUI from the applet.

	* usr/share/time-slider/lib/time_slider/dbussvc.py:
	  Add class and method definition for TimeSlider Config service
	  notifications.

	* usr/share/time-slider/lib/time_slider/setupgui.py:
	  Register with system D-Bus and send notification of changes
	  to time-slider and rsync plugin services so the applet can
	  refresh.

2010-05-13 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Fix list IndexError exception caused by looking
	  for non-existent backups on an empty device.
	
2010-05-11 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Tweak the space management of the rsync device for better
	  performance:
	  - don't scan for deleteables unless the device starts to 
	    exceed threshhold capacity.
	  - Rescan capacity periodically during rsync backup thread
	    lifecycle and rescan for deleteable backups only if
	    device exceeds threshold capacity level.

2010-05-11 Niall Power - <niall.power@oracle.com>

	* var/svc/manifest/system/filesystem/auto-snapshot.xml:
	  Update service bundle name and version number to 
	  SUNWtime-slider and 0.2.96 respectively.

	* var/svc/manifest/application/time-slider-plugin.xml:
	  Add 2 new properties to define cleanup threshhold level of
	  rsync backup device and verbosity of rsync output for
	  debugging purposes.

	* usr/share/time-slider/lib/time_slider/util.py: Adjust
	  signature of util.debug() to make the verbose argument 
	  mandatory instead of automatic.

	* usr/share/time-slider/lib/plugin/rsync/rsyncsmf.py:
	  Add 2 new methods to retrieve cleanup threshhold and rsync
	  verbosity properties from the rsync SMF service instance.

	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Cleanup variable naming, making class private variables
	  actually private using leading "_" character.
	  Rename RsyncBackup class to RsyncProcess to me more descriptive.
	  Add support for rsync verbosity in RsyncProcess class.
	  Implement better cleanup and space management mechanism:
	  - Removes old backups in parallel to new rsync backups running
	    in a separate thread if space falls below threshhold level.
	  - Identifies what backups can and can't be deleted for a given
	    new rsync backup based on age and number of backups left for
	    the associated filesystem.
	  - Cleanup threshhold tuneable via SMF atic.

	* usr/share/time-slider/lib/plugin/rsync/rsyncsmf.py:
	  Add 2 new methods to retrieve cleanup threshhold and rsync
	  verbosity properties from the rsync SMF service instance.

	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Add check to make sure config key on target device matches that
	  stored in SMF before commencing backups.
	  Cleanup variable naming, making class private variables
	  actually private using leading "_" character.
	  Rename RsyncBackup class to RsyncProcess to me more descriptive.
	  Add support for rsync verbosity in RsyncProcess class.
	  Implement better cleanup and space management mechanism:
	  - Removes old backups in parallel to new rsync backups running
	    in a separate thread if space falls below threshhold level.
	    Avoids having to make rough, inaccurate guesses about size 
	    required for new backups because it responds in real time.
	  - Identifies what backups can and can't be deleted for a given
	    new rsync backup based on age and number of backups left for
	    the associated filesystem.
	  - Cleanup threshhold tuneable via SMF.
	  - Doesn't try to backup snapshots older than what's already on
	    the backup device if device is almost full.
 
2010-05-05 Niall Power - <niall.power@oracle.com>
	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Redesigned queue management and backlog mechanism. Backs up
	  most recent snapshot set first, then works backwards through
	  the queue. Stops backup mechanism falling too far behind while
	  still allowing backup of older snapshots to take place if
	  time and space permit.
	  Enhancements to filesystem layout of backups - added seperate
	  folders for partial transfers, log files, trash folder and lock
	  files. Added file locking mechanism to prevent deletion by other
	  tools of backups in use (eg during incremental backups).
	  Added trash mechanism, replaces in place deletion of snapshots
	  which messes up directory mtimes and incremental backups.
	  Instead, expired backups are moved to a .trash folder and a new
	  method: empty_trash_folders() cleans it up after before starting
	  the next snapshot set backup.
	  Fix bug in list_pending_snapshots() where ctime of snapshots was
	  returned as a string instead of a long.

	* usr/share/time-slider/lib/plugin/rsync/rsyncsmf.py: Add new 
	  filesystem suffix definitions for partial backups, trash
	  folders, backup lock files and backup log files.

2010-05-03 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/time_slider/timesliderd.py:
	  Determine if <zpool/remedial-cleanup> SMF property is set to true.
	  Do not perform remedial cleanups if it's value is false.

	* usr/share/time-slider/lib/time_slider/timeslidersmf.py:
	  Add new method: get_remedial_cleanup() to indicate the value of
	  property <zpool/remedial-cleanup>

	* var/svc/manifest/application/time-slider.xml:
	  Add new SMF property: <zpool/remedial-cleanup> as boolean with
	  default value of 'true'. Indicates that time-sliderd should
	  perform remedial cleanups when snapshotted pool runs low on
	  space.

2010-05-03 Niall Power - <niall.power@oracle.com>

	* Makefile:
	  Install/uninstall time-slider.desktop into 
	  $(DESTDIR)/usr/share/applications/

2010-05-02 Niall Power - <niall.power@oracle.com>

	* lib/svc/method/time-slider:
	  Remove any legacy zfs-auto-snapshot cron jobs in
	  zfssnap's crontab that may not have been removed
	  if the old auto-snapshot services were not stopped
	  cleanly.

2010-05-02 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/time_slider/timesliderd.py:
	  Fix incorrect invocation of util.debug() that caused
	  unconditional verbose output.
 
2010-05-02 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/time_slider/timesliderd.py:
	  Fix small typo in monthly calculation.

2010-05-02 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Instantiate RsyncBackup objects with verbose flag
	  passed through. Remove "--progress" argument from
	  rsync and add "-vv" argument instead if verbose
	  flag is set.

2010-05-01 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/plugin/plugin.py: Fix some
	  incorrect invocations that didn't pass verbose
	  parameter (and were therefore no-ops)

	* usr/share/time-slider/lib/time_slider/timesliderd.py:
	  Fix monthly period calculation. Now handles period
	  increments > 12 months and period increments that
	  land on december (originally logged as bugster
	  CR #6904417)

2010-05-01 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/time_slider/setupgui.py:
	  Cache all GUI configuration values at startup and
	  use them later to compare changes in configuration
	  state. Only apply the minimum set of configuration
	  changes necessary instead of previous method of
	  blindly applying everything, even if unchanged.
	  Configuration is much much faster now, especially
	  for minor configuration changes.
	  Recognise previously configured backup devices and
	  ask the user if they want to start using it again
	  instead of rejecting it as belonging to another 
	  system.
	  Remove duplicate import of os.path modules.

2010-04-28 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Add removal of partial backups missing a  matching 
	  snapshot in the backup queue. They are zombies.
	  When catching an rsync exception, change directory
	  to "/" so that pfexec doesn't freak out when trying
	  to release the snapshot. pfexec bails out when it
	  tries to add cwd to it's path if cwd is non-existent 
	  which can be the case if the backup device suddenly
	  goes offline.

2010-04-27 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Remember to also delete log files when deleting backups.

2010-04-27 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Exit if effective UID of process is not 0 (root)

2010-04-27 Niall Power - <niall.power@oracle.com>

	* usr/share/time-slider/lib/plugin/rsync/backup.py:
	  Send rsync loggint to individual log files on the backup
	  device. Delete log files when corresponding backup gets
	  deleted.
	  Create rsync backups in a temporary directory first and
	  move to permanent location when completed. Prevents 
	  incomplete backups appearing in backup view in Nautilus.
	  Also use "--inplace" rsync option to allow resumption of
	  partial (interrupted) backups.

	* usr/share/time-slider/lib/plugin/rsync/rsyncsmf.py:
	  Add shared key get/set methods for rsync SMF instance.
	  Use new "set_string_prop" Smf class method for setting
	  rsync target directory so that path names containing 
	  spaces can be correctly set. Conversely, strip out '\ '
	  space formatting characters returned by SMF in 
	  get_target_dir() method.

	* usr/share/time-slider/lib/plugin/rsync/trigger.py:
	  Don't tag new snapshots whose filesystems are not mounted
	  Prevents piling up of snapshots from unmounted BEs. Might
	  be best to make this behaviour configurable via SMF.

	* usr/share/time-slider/lib/time_slider/setupgui.py:
	  Clean up OK button clicked callback by farming out several
	  validation checks to separate methods. Add rsync config
	  checking method to chek configuration/selection of rsync
	  target device. Implement shared key checking to validate/
	  identify pre-configured backup devices. Rejects devices
	  configured for use on other systems. Add checks to ensure
	  target device is writable by root and supports hard links
	  as required for rsync incremental backups. Add a random
	  key generation function. Perform basic space checking on
	  rsync target device to see if it's big enough.

	* usr/share/time-slider/lib/time_slider/smf.py:
	  Implement set_string_prop() method that allows white space
	  string characters.

	* var/svc/manifest/application/time-slider-plugin.xml:
	  Remove rsync plugin's property override of
	  <plugin/trigger_on> and inherit defaults instead. Backing
	  up frequent snapshots caused near constant backup disk
	  churn.

2010-04-16 Niall Power - <niall.power@sun.com>

	* usr/share/time-slider/lib/time_slider/zfs.py: Fix bug in 
	  method "create_auto_snapshot_set() where it would skip
	  the entire pool if the root of the pool was tagged and 
	  all datastets under the root inherited from it. Also,
	  use sorted lists and binary searching to speed up the
	  operation and avoid making repeated unnecessary calls
	  to Dataset.list_children() (the data is already provided)

2010-04-15 Niall Power - <niall.power@sun.com>

	* usr/share/time-slider/lib/plugin/rsync/backup.py: Clean up 
	  dangling holds on snapshots left by abnormally terminated
	  rsync transfers from previous invocations. Also, release
	  snapshot holds if an Rsync exception is caught during
	  transfer. Allows time-sliderd to delete snapshots when they
	  naturally expire.

2010-04-13 Niall Power - <niall.power@sun.com>
	* usr/share/time-slider/lib/time_slider/setupgui.py:
	  Fix broken target directory retrieval from FileChooser button

2010-04-13 Niall Power - <niall.power@sun.com>

	* usr/share/time-slider/lib/plugin/rsync/backup.py: Create a
	  RsyncBackup class to run rsync backup commands in a 
	  separate thread. Define Rsync exception clases and map
	  to expected rsync exit codes.
	  Modify toplevel backup path for backups to begin with:
	  <SMF defined target dir>/TIMESLIDER/<nodename>/
	  Deal with rsync exceptions raised and place into maintenance
	  state if non recoverable.
	  Try to recover space on target directory (work in progress)
	  Add debugging and error logging output.

	* usr/share/time-slider/lib/plugin/rsync/rsyncsmf.py: define
	  backup RSYNCDIRPREFIX to "TIMESLIDER".

	* usr/share/time-slider/lib/time_slider/applet.py:
	  Use new backup path format as described above.

	* usr/share/time-slider/lib/time_slider/setupgui.py:
	  Use new backup path format as described above.

	* usr/share/time-slider/lib/time_slider/util.py:
	  Add general purpose syslog wrapper function.

	* var/svc/manifest/application/time-slider-plugin.xml:
	  remove accidental definition of <plugin/target_dir>
	  Set to empty string value "" instead of a directory on my
	  own system. Doh.

2010-04-01 Niall Power - <niall.power@sun.com>

	* usr/share/time-slider/lib/time_slider/timesliderd.py: insert a
	  'h' character between hour and minute values of auto snapshot
	  labels as a subsitute for the previously removed ':' character
	  used in time stamps. Makes life easier for nautilus component
	  and plays nicely with strptime()

2010-04-01 Niall Power - <niall.power@sun.com>

	* usr/share/time-slider/lib/time_slider/applet.py: gio FileMonitor
	  events are inconsistent between UFS/ZFS filesystem mounting.
	  Ignore event type from gio FileMonitor and verify backup target
	  status manually using os.stat()

2010-04-01 Niall Power - <niall.power@sun.com>

	* usr/share/time-slider/lib/time_slider/applet.py: Improve string
	  formatting on notifications and tooltips. Stop the status icon
	  blinking once the notification has been closed.
	* usr/share/time-slider/lib/time_slider/setupgui.py: Forgot to
	  connect rsync folder selection to rsync SMF instance
	  configuration. Added. Also use get_current_folder() instead of
	  get_filename() to get correct folder from FileChooserButton
	  widget.

2010-03-31 Niall Power - <niall.power@sun.com>

	* usr/share/time-slider/lib/time_slider/applet.py: Restrict manual
	  synchronisation menu item to priviliged users only (root or
	  users assigned Primary Administrator profile). Also, don't
	  bother popping up a right click menu if it's empty.

2010-03-31 Niall Power - <niall.power@sun.com>

	* usr/share/time-slider/lib/plugin/rsync/backup.py: Implement cleanup
	  of expired backups on rsync target directory. Uses same rules as
	  time-slider as defined by each auto-snapshot schedule's SMF instance
	* usr/share/time-slider/lib/plugin/rsync/rsyncsmf.py: Add a method to
	  return the list of archived schedules (ie. ones that don't get 
	  cleaned according to the normal schedule retention rules)
	* usr/share/time-slider/lib/time_slider/applet.py: add a 
	  'Synchronize Now' menu item to the applet. Added gio based file
	  monitoring to keep track of when the rsync backup target directory
	  is mounted/unmounted and adjust menu sensitivty accordingly.
	* usr/share/time-slider/lib/time_slider/autosnapsmf.py: Define 
	  SNAPLABELPREFIX as a constant for snapshot label names
	* usr/share/time-slider/lib/time_slider/setupgui.py: Modify RBAC
	  rules to ensure that setup GUI is run with euid of root which is
	  necessary for validation and initialisation of rsync backup target
	  directory
	* usr/share/time-slider/lib/time_slider/timesliderd.py: use 
	  SNAPLABELPREFIX constant instead of local multiply defined values.
	* var/svc/manifest/application/time-slider-plugin.xml: Override
	  "plugin/trigger_on" value in rsync plugin manifest. Add a new
	  property "rsync/archived_schedules" to define snapshot schedules
	  that are archived as long as possible and not purged according
	  to the normal schule retention rules.

2010-03-25 Niall Power - <niall.power@sun.com>

	* etc/dbus-1/system.d/time-slider.conf: add policies for
	  rsync plugin's dbus service and methods.
	* usr/share/time-slider/lib/plugin/rsync/backup.py: restructure script
	  to perform backups via a Gobject mainloop which is necessary to allow
	  it to send dbus notifications correctly. Adjust backup target dir
	  to use a rsync plugin specific subdirectory on the target dir
	  (.time-slider/rsync) - prevents borkage of mount points with 
	  unmounted filesystems. Use "-a" option with rsync command which 
	  covers all the desired arguments fo our rsync usage case (archival)
	  Add dbus method invocations. General cleanup and removal of commented
	  out code. Use lockfile to prevent multiple instances running at once.
	* usr/share/time-slider/lib/plugin/rsync/rsyncsmf.py: Add definitions
	  for backup subdirectory and filesystem property tag constants.
	* usr/share/time-slider/lib/plugin/rsync/trigger.py: Use constants as
	  defined in rsyncsmf.py
	* usr/share/time-slider/lib/time_slider/applet.py: Incorporate new 
	  RsyncNote class and other pieces from Krishnan Parthasarathi. Thanks
	  Krishan. Added signal handlers and tooltips/popups for dbus events 
	  sent from rsync plugin.
	* usr/share/time-slider/lib/time_slider/dbussvc.py: New dbus signal
	  definitions added, including a few from Krishnan.
	* usr/share/time-slider/lib/time_slider/setupgui.py: Perform validation
	  on target directory for rsync. Not exhaustive yet. Checks that target
	  directory isn't on a file system or pool that's been selected for
	  automatic snapshots.

2010-03-11 Niall Power - <niall.power@sun.com>

	Add rsync plugin (WORK IN PROGRESS), restructure SMF related code
	and restructure file/directory layout to provide seperate 
	subdirectories for plugins.

	* Makefile: Add/remove files to (un)install rules.

2010-02-04 Niall Power - <niall.power@sun.com>

	* Makefike: Add lib/svc/method/time-slider-plugin to
	  install/uninstall rules.
	* lib/svc/method/time-slider-plugin: Added.
	  Provides simple, generic plugin start method.
	* var/svc/manifest/application/time-slider-plugin.xml:
	  Added comments for time-slider-plugin method, advising
	  that non trivial plugin instances should provide their
	  own specific methods.

2010-02-03 Niall Power - <niall.power@sun.com>

	* var/svc/manifest/application/time-slider.xml:
	  Define new property "zfs/sep". Taken for zfs-auto-snapshot,
	  allows custom definition of a separator character for snapshot
	  datestamps that can work on filesystems that previously choked
	  on the ":" characted such as CIFS, PCFS.
	* usr/share/time-slider/lib/time_slider/smfmanager.py: Added new
	  method to get zfs/sep property.
	* usr/share/time-slider/lib/time_slider/timesliderd.py: modify
	  snapshot creation and listing operations to use the new zfs/sep
	  property, while maintaining compatibility with old snapshot
	  datestamps that used the ":" character.

2010-02-02 Niall Power - <niall.power@sun.com>

	* usr/share/time-slider/lib/time_slider/plugin.py:
	  Fix invalid function call "debug()" should be "util.debug()" when
	  reporting disabled plugin in PluginManager.refresh()
	  Missing "()" in method call Plugin.is_running() in Plugin.refresh()

2010-01-26 Niall Power - <niall.power@sun.com>

	* VERSION: bump to 0.2.96
	* Use explicit path: "/usr/bin/python2.6" to reference python interpreter
	  instead of relying on "/usr/bin/env" to find it.
	* Add plugin framework to enable user defined plugins to be executed after
	  snapshots get taken by time-sliderd. Plugins are based on the SMF service
	  framework and plugins are defined as instances of the base SMV service:
	  svc:/application/time-slider/plugin
	* Provide a "zfs-send" plugin as a replacement for the zfs-auto-snapshot
	  provided "backup-save-cmd" property.
	* Add util.py to define two commoonly used utility functions: debug/logging
	  and command spawning. Reduces lines of code and duplication.
	* Refactor all python files to use util.run_command() convenience function
	  where possible.
	* Fix a bug where time-sliderd emits warnings and tries to cleanup pools
	  upon which it creates no snapshots. Also make time-sliderd more descriminating
	  in general and able to identify snapshots it created from backups of snapshots
	  it create (via zfs send/receive) by checking for the auto-snapshot property
	  corresponding to the filesystem/volume of snapshots.
	* TODO: SMF code is a bit all over the place and could do with proper stucturing

2009-11-27 Niall Power - <niall.power@sun.com>

	* usr/share/time-slider/lib/time_slider/timesliderd.py: fixed a date
	  calculation bug whereby a schedule with a period in months next falls
	  due on December. Was getting incorrectly modulused to 0.

2009-11-04 Niall Power - <niall.power@sun.com>

	* VERSION: bump to 0.2.95
	* Move to python2.6
	* Drop dependency on zfs-auto-snapshot methods and implement our own
	  snapshotting mechanism in the form of time-sliderd
	* Add dbus system bus notification and notification applet, replacing
	  the previous ugly hack of su to logged in user ID and running
	  notify-send.
	* Enhance all .py modules to use python subprocess module when spawning
	  commands instead of os.popen.
	* Add SMF manifest for system/filesystem/auto-snapshot to replace 
	  systems snapshot configuration previously supplied by
	  zfs-auto-snapshot. Generally compatible but cleaned up by dropping
	  some of zfs-auto-snapshot's more quirky or deprecated configuration
	  options.

2009-07-08 Niall Power - <niall.power@sun.com>

	* VERSION: bump to 0.2.10

	  refactoring to match zfs.py API changes.
	* usr/share/time-slider/lib/time_slider/setupgui.py: Remove references
	  to zfscontroller module which has been removed. Uses zfs.py 
	  exclusively now. Refactor for zfs.py changes
	* usr/share/time-slider/lib/time_slider/zfscontroller.py: removed.
	  Very little functionality and nothing that shouldn't be in zfs.py
	* usr/share/time-slider/lib/time_slider/zfs/py: New class definition
	  for "Datasets" which stores all system snapshots, filesystems and
	  volumes in a cache. Existing Dataset, Filesystem, Snapshot and Volume
	  class methods now use the global Datasets cache for querying and
	  listing instead of making zfs(1m) spawned commands.

2009-05-18 Niall Power - <niall.power@sun.com>

        * usr/share/time-slider/lib/time_slider/cleanupmanager.py

        * usr/share/time-slider/lib/time_slider/setupgui.py: Prepend private
          class methods with "__" in accordance with python coding standards.
        * usr/share/time-slider/lib/time_slider/smfmanager.py: Use predefined
          macros for ZFS commands instead of hardcoding path in the code.
        * usr/share/time-slider/lib/time_slider/zfs.py: Improve object
          hierarchy and inheritance tree. Rename some methods for improved
          clarity of purpose. Improve method and function documentation.
          Add capability to deal with ZFS volumes. Fixes d.o.o 8454 & 8685

	  every filesystem with the required property setting.
	* usr/share/time-slider/lib/time_slider/zfs.py: Add an "inherit" argument
	  to Filesystem.commit_state() to allow the fileystem to inherit from
	  it's parent when setting the auto-snapshot property.
