Notes:
Release Name: 3.2.7

Notes:



Changes:
== 3.2.6

* Upgraded to JSON 1.1.7
* Added a guard to skip loading JSON when Rails has already done it for us

== 3.2.6

* Upgraded to Amalgalite 0.10.0
* Added an extra Timeout.timeout() loop to all API requests in an attempt to
  avoid Net::HTTP hanging on server errors

== 3.2.5

* Added a workaround for an issue in RestClient 1.0 (an incorrect error)

== 3.2.4

* Fixed a bug with Symbol keys when queuing Marshal data

== 3.2.3

* Upgraded to JSON 1.1.6
* Upgraded to RestClient 1.0 for improved SSL support
* Added SSL certificate verification to the agent so it will only communicate
  with the trusted Scout server
* Added support for Marshal data when queuing reports or messages
* Switched the API to use Marshal to avoid JSON conflicts with Rails
* Improved mission error messages where possible
* Fixed a bug where certain API requests could die with a networking Exception
* Fixed a bug where the API would fail to recognize certain valid plugin ID's
* Fixed core extension tests

== 3.2.2

* Fixed a bug where older versions of the standard timeout library could kill
  the lifeline monitoring process

== 3.2.1

* Fixed a bug where log shifting failures could cause the agent to crash

== 3.2.0

* Fixed a bug where the API would require the wrong version of the JSON library

== 3.1.9

* Restoring some error handling code that was accidentally disabled
* Fixed an issue where the agent could accidentally launch a duplicate process
* Fixed an issue that prevented the agent from forcing a stop when a process
  would timeout on a signal response

== 3.1.8

* Switching XMPP default to off until we enable that feature
* Added a queue_for_plugin() alias to the API for queue_for_mission()
* Added some examples to the API documentation

== 3.1.7

* Reverting DNS changes due to other severe issues they caused (you can switch
  to Ruby's resolv with `ruby -r resolv-replace scout_agent start`, if needed)

== 3.1.6

* Fixed a bug that would cause blank errors to show up in the Web application

== 3.1.5

* Fixed a bug that could cause the agent to crash when shutting down if running
  with --no-daemon
* Switched DNS strategies so slow DNS resolving doesn't kill our background
  threading for process monitoring
* Relaxed the process monitoring timeout to ten seconds
* Relaxed TERM to KILL timeouts to five seconds
* Unwound some metaprogramming magic so some missing methods would show up in
  the documentation

== 3.1.4

* Modified the API to no longer load the JSON gem if we already have JSON
  capabilities (for example, ActiveSupport provides it in Rails)

== 3.1.3

* Modified file modes to match lock types to get the file locking code running
  on Solaris
* Fixed a variable name conflict
* Cleaned up some of the mission error catching code

== 3.1.2

* Fixed a bug that caused the mission tester to error out when trying to update
  the mission memory

== 3.1.1

* Switched the default URL to the production server

== 3.1.0

* Fixed a bug where the monitor might not properly signal all subprocesses
* Made the master agent forward shutdown requests to running missions
* Enhanced the stop command to ensure all processes exit and to skip the waits
  on KILL signals since they cannot be responded to
* Improved the error message for forced stops to give next steps
* Fixed a bug that would prevent the agent from daemonizing itself at start-up
  if it had to clean out a stale PID file first
* Added status database and log file maintenance to the snapshot and queue
  commands
* Completed full code documentation and clean-up pass

== 3.0.7

* Added a log() method (with a logger() alias) plugins can access to add
  messages to the log as needed
* Added JSON hooks for the Time class so they will be converted back to Ruby
  objects when loaded
* Added a `scout_agent test` command for plugin developers
* Switched to the default URL of https://beta.scoutapp.com
* Improved the error handling in the communications agent for connection failure
  scenarios like blocked ports (fixes a CPU pegging bug)
* Loosened error checking when killing processes to improve monitor stability
* Loosened the check-in timeout a touch as the monitor seemed to kill off
  processes a little too quickly
* Enhanced the monitor to kill off mission processes after killing the mission
  runner
* Made the stop command hunt for stray processes after stopping the monitor
  process

== 3.0.6

* The new `sudo scout_agent update` command can be used to update your
  configuration file
* Made it possible to disable XMPP for a smaller memory footprint
* Restricted XMPP commands to a white list for added security
* Added an optional "force" argument for `scout_agent snapshot` that clears
  command run times before running to ensure a full snapshot
* Modified XMPP snapshots to use the new force option for snapshots to ensure
  requests from users via the Web interface are always honored
* Added a periodic_snapshots configuration option that defaults to true and will
  cause the agent to attempt a snapshot before each check-in (though command 
  intervals will usually only allow them to be run every few check-ins)
* Fixed a bug that could cause snapshots to temporarily orphan a process and/or
  to unnecessarily delay API requests
* Fixed a bug that could cause the agent to crash if it had trouble killing off
  a spawned process

== 3.0.5

* Added support for XMPP message SHA, instead of just an ID

== 3.0.4

* Upgraded to Arrayfields 4.7.3 to silence a warning on Ruby 1.9
* Added HTTP proxy support
* Added replies to acknowledge received messages from XMPP when a message ID is
  included in the command
* Turned XMPP on and aimed it at the real Scout server
* Greatly improved error handling for the XMPP process
* Added logging and status tracking for the XMPP operations

== 3.0.3

* Upgraded to JSON 1.1.4 for Ruby 1.9 compatibility

== 3.0.2

* Added xmpp4r gem dependency
* Locked gem version numbers at load time
* Upgraded to Amalgalite 0.9.0 for Ruby 1.9 compatibility
* Upgraded to RestClient 0.9.2 to remove a couple of bug workarounds
* Changed the API to always shell out to the same version of Ruby it is running
  under
* Made a first pass at Ruby 1.9 support

== 3.0.1

* Added more error protection to the server wrapper so thinks like
  OpenSSL::SSL::SSLError and SocketError don't kill the agent
* Switched to the beta URL

== 3.0.0

* Initial release
