1.34 2010-08-06 Bug fix release, update not required

• Implemented work-around for RT:53909

  The issue demonstrated here, which can be observed in perl versions newer than 5.10.0 seems to be related to RT:70171:

  RT:53909 is based on blead perl, in which also a fix has now been implemented, but we still have issues with a lot of perl releases currently out there, see tests of release 1.33_1

  So this work-around seems to fix the issue, since I can no longer replicate the error. The problem seem to be the clearing of a package scoped variable, the array @observations in t/SomeObserver.pm

• Fixed example application, it was relying on a test module in a broken way, a path processed using a regex was not reliable

1.33 2010-01-30 Bug fix release, update not required

• Patch from Ivan Paponov, bug in relation to action groups and use of default. Bumping up version of Workflow::Factory to 1.19 and Workflow::State to 1.15

• Patches from Alejandro Imass

  • Changed @FIELDS to @PROPS in Action.pm and InputField.pm for mk_accesors as FIELDS was very confusing with regard to action input fields.

  • Formalized Workflow::Action::new() as a public method with corresponding pod example.

  • Optional class property for Workflow::Action::InputField. Previously, public method new() made little sense if InputField always instantiates from Workflow::Action::InputField. Now fields can derive from custom class.

  • Updated pod to reflect the new formal abillity to add extra properties for actions and input fields.

  • With the ability to derive custom properties for classes and fields there is little need IMHO to define InputField "type" any further, but leave it implementation dependent. The rationale is that validators intrinsically define this. Updating pod accordingly.

• Patches from Thomas Erskine

  • Added 3 new accessors to Workflow::Factory:

    • get_persister_for_workflow_type
    • get_persisters
    • get_validators

  • Added check for existing context so context is not overwritten if existing, fixing a bug. Version bumped up to 1.19

  • Fixing bug in Workflow::Persister::File, adding context parameters to serialization. Version bumped up to 1.11

  • Added return of empty list for accessor, in Workflow::Action. Version bumped up to 1.10

• Patches from Danny Sadinoff to following classes

  • Workflow::Config, bumped up to version 1.13

  • Workflow::Persister, bumped up to version 1.10

  • Workflow::Factory, bumped up to version 1.19

  • Adding ability to control initial state name via workflow config

  • Adding ability to control initial history record details via Persister subclass code

• Addressing a bug reported by Sergei Vyshenski, related to a possible API breakage. Please refer to t/add_config_bug.t, which demonstrates the presence of the bug in 1.32 and it's absence in 0.31. Workflow::Factory bumped up to version: 1.19

• Applied patch from Andrew O'Brien implementing dynamic loading of config files RT:18265. Bumped up version for Workflow::Factory to 1.19

1.32 2009-01-26 Bug fix release, update not required

• Bumped up version for Workflow::State to 1.14 considering patches from action_group and test_condition patches from Ivan Paponov implementing support for a group tag on actions

• Addressing RT:40750

  Removed VERSION file, this has now been obsoleted

  We are now resolving the version number for the distribution from Workflow.pm the main module, this mean a jump from 0.31 to 1.32, but it does mean that an installation can be traced back to a given distribution

• Patch to implement proper dynamic names for conditions with a 'test' attribute, ref RT:38024

• Added List::MoreUtils to requirements, we use this for test, I have moved the test related modules to the build_requires section in Build.PL, so List::MoreUtils is not mistaken for an application level requirement

• Refactored two tests, to use List::MoreUtils all method (asserting presence of numerous actions)

• Fixed minor bug in error message in: Workflow::State, reported by Robert Stockdale, RT:38023

• We introduce a more fine grained control of the auto commit feature, implemented by Jim Brandt

• We introduce typed condition, implemented by Jim Brandt. Typed conditions makes it possible for different workflows to hold unique methods for workflow steps even with names colliding.

  Example workflow foo and bar can have a condition baz, but baz are two different implementations in foo and bar respectively

• time_zone parameter can now be passer around for use by the Workflow DateTime objects internally

0.31 2007-09-26 Bug fix release, update not required

• Fixed failing tests in t/persister_dbi.t, this has only observed twice and does not seem to be consistent. This is related to execution time for the test suite and the use of now, using the debugger would demonstrate this

  Resolves: RT:29037

• Cleaned TODO file a bit

• Added Data::Dumper requirement to Build.PL

0.30 2007-09-25 Bug fix release, update not required

• Added patch from Jim Brandt improving handling of date formats for real, the merge into 0.29 (see below) was not completed

  The patch also addresses RT:29037

  which is related to a report on a failing test

0.29 2007-09-24 Maintenance release, update not required

• Added new test file: t/persister.t for Workflow::Persister

• Updated t/confition.t for better coverage

• Updated t/action.t for better coverage

• Updated t/validator.t for better coverage

• Updated Workflow::Action::Mailer (stub now can be tested, this might however prove to be a bad idea)

• Added new test file: t/action_mailer.t for Workflow::Action::Mailer

• Updated t/action_null.t for better coverage

• Added some more tests t/Config.t

0.28 2007-07-06 Maintenance release, update not required

• Removed TODO.txt, the files contents have long gone been merged into the TODO file

• Added a new file to the doc/ directory named developing.txt. This is a collection of documentation notes on maintaining and developing the Worksflow distribution

• Renamed Action::Mailer to Workflow::Action::Mailer, this however still looks like a stub that was never finished

• Added more POD to:

  • Workflow

  • Workflow::Action::InputField

  • Workflow::Action::Mailer

  • Workflow::Condition

  • Workflow::Condition::HasUser

  • Workflow::Config::XML

  • Workflow::Factory

  • Workflow::History

  • Workflow::Persister

  • Workflow::Persister::DBI

  • Workflow::Persister::DBI::ExtraData

  • Workflow::Persister::DBI::AutoGeneratedId

  • Workflow::Persister::DBI::SequenceId

  • Workflow::Persister::RandomId

  • Workflow::Persister::File

  • Workflow::Persister::SPOPS

  • Workflow::State

  • Workflow::Validator::HasRequiredField

    We now have a POD coverage of 100%, this does however not say anything about the quality of the spelling or POD. All POD will however be revisited at some point

    Please remember to document changes and additions

• Implemented conditional tests in t/00_load.t for SPOPS and UUID. These are conditional in their own tests, so this should of course be reflected in t/00_load.t

  This should address the report on a failing test

• Added missing version number to Workflow::Persister (1.09), the PAUSE indexer complained over degrading version number, investigating consequences

  No apparent consequences

0.27 2007-07-03 Bug fix release, update not required (see note below)

• Update not required unless you are using 0.26 or 0.25

• Fixed bug in cached condition handling (0.26 reintroduced the original race condition that was solved using the condition cache in 0.25). Condition cache is now cleared on state change and when calling get_available_action_names()

• Updated some tests, nothing serious we are just on the way to better test coverage and documentation

• Added more POD to:

  • Workflow::Action
  • Workflow::Exception
  • Workflow::Persister::RandomId.pm
  • Workflow::Persister::UUID.pm
  • Workflow::Validator::MatchesDateFormat
  • Workflow::Validator::InEnumeratedType

• Added more tests of Workflow::Validator::MatchesDateFormat to t/validator_matches_date_format.t

• Added more tests of Workflow::Validator::InEnumeratedType to t/validator_in_enumerated_type.t

• Small fix to a test on an empty array. Empty arrays evaluate to false t/config.t, cleaned some code in Workflow::Config and Workflow::Config::Perl nothing significant

• Hard coded version numbers to all modules in t/ Subversion uses different scheme so we no longer use automatically updated version numbers, added version 0.01 where no version was present

• Hard coded version numbers to all modules in eg/

  Subversion uses different scheme so we no longer use automatically updated version numbers, added version 0.01 where no version was present

• Eliminated warning in Workflow::Factory, in check for FACTORY parameter

• Added t/00_load.t, de facto usage syntax test catches compilation errors etc.

• Applied patch from Jim Brandt to Workflow::Config::XML, the patch helps to catch bad XML

  Updated version to 1.05

• Hard coded latest versions from CPAN to all modules, Subversion uses different scheme so we no longer use automatically updated version number.

  • Action::Mailer 1.01
  • Workflow 1.32
  • Workflow::Action 1.09
  • Workflow::Action::InputField 1.09
  • Workflow::Action::Null 1.03
  • Workflow::Base 1.08
  • Workflow::Condition 1.07
  • Workflow::Condition::Evaluate 1.02
  • Workflow::Condition::HasUser 1.05
  • Workflow::Config 1.11
  • Workflow::Config::Perl 1.02
  • Workflow::Config::XML 1.04
  • Workflow::Context 1.05
  • Workflow::Exception 1.08
  • Workflow::Factory 1.18
  • Workflow::History 1.09
  • Workflow::Persister 1.09
  • Workflow::Persister::DBI 1.19
  • Workflow::Persister::DBI::AutoGeneratedId 1.06
  • Workflow::Persister::DBI::ExtraData 1.05
  • Workflow::Persister::DBI::SequenceId 1.05
  • Workflow::Persister::File 1.10
  • Workflow::Persister::RandomId 1.03
  • Workflow::Persister::SPOPS 1.07
  • Workflow::Persister::UUID 1.03
  • Workflow::State 1.13
  • Workflow::Validator 1.05
  • Workflow::Validator::HasRequiredField 1.04
  • Workflow::Validator::InEnumeratedType 1.04
  • Workflow::Validator::MatchesDateFormat 1.06

• Fixed a problem in t/workflow.t which rely on DBI. DBI is not necessarily present, since this is not a requirement (DBD::Mock is), so I have made the test conditional as to whether DBI is installed as for some of the other tests.

  This should address the 'N/A' status of the test report

• Updated MANIFEST

• Added t/03_pod-coverage.t, de facto POD coverage test, set the environment variable TEST_POD to enable the test

  Currently we have BAD POD coverage so the test fails.

• Added t/02_pod.t, de facto POD syntax test, set the environment variable TEST_POD to enable the test

0.26 2007-03-07 Bug fix release, update not required, see note below

• Update not required unless you are using 0.25

• Fixed bug in cached condition handling. The condition cache is now cleared before checking conditions so that the condition results are not taken from the cache when entering the same state again

• Fixed small bug in the error message when autorunning is enabled but more than one action is available (now displays the names of these actions correctly)

0.25 2006-12-14 Feature release, update not required

• Applied patch from Alexander Klink via #23736. Introduces caching of the result of a condition's evaluate()

0.24 2006-12-14 Feature release, update not required

• Applied patch from Alexander Klink via #23925. Introduces may_stop property for autorunning workflow

  This is why this patch introduces the "may_stop" property for a state, which means that Workflow won't complain if the state is autorun and no or too many activities are present.

0.23 2006-09-12 Feature release, update not required

• Applied patch from Michael Bell via #21100. Fixes problem with handling of 0 and empty strings as parameters

• Applied patch from Michael Bell via #21101. Fixes problem with deletion of parameters

• Applied yet another patch from Michael Bell via #21099. The patch fixes some misinforming POD

• Applied patch from Alexander Klink via #21422. The patch implement more powerful observers

0.22 2006-08-18 Feature release, update not required

• Applied patch from Michael Bell via #20871, this patch also contains the patch mentioned below.

• Applied patch to Workflow::Action from Michael Bell, fixing two bugs

• Changed POD format to accomodate for Pod::Coverage, where B<> is not recognised, but =head<1..3> and =item is

  So subs are now marked with head3 instead of B<>, I am of the opinion that titles should be marked as titles and B<> (bold) should be used to emphasize important information in the POD.

0.21 2006-07-07 Bug fix release, update not required

• Fixed bug reported by Martin Bartosch, Workflow::Context's merge method did not work properly, applied patch from Martin

• Updated t/context.t to test the above fix, this got the coverage from 53.3 percent to 93.3

0.20 2006-07-07 Bug fix release, update not required

• Fixed bug reported by Martin Bartosch, Workflow::Factory's add_config_from_file now takes an array ref as stated in the POD.

• Updated t/factory.t to test the above fix, just using the scenarios from the SYNOPSIS. This fix did however not contribute to the coverage of Workflow::Factory, we lost 0.3 percent along the way going from 88.7 to 88.4

• Fixed two POD errors in Workflow::Config

0.19 2006-07-07 Bug fix release, update not required

• The 0.18 release contained a broken Makefile.PL, thanks to Randal Schwartz for sending me the feedback to get this addressed immediately.

0.18 2006-07-07 Maintenance release, update not required

• New maintainer, JONASBN has taken over maintenance of Workflow

• Added maintainer information to Workflow.pm

• Added new TODO file

• Added a handful of tests to t/config.t and added dependency on Test::Exception

• Somewhat applied patch from Chris Brown, the use of Perl as configuration was broken, in my attempt to implement tests prior to applying Chris Browns patch I accidently fixed the same problems it addressed.

  Coverage of Workflow::Config::Perl has gone from 0 to 89.0 with this release

• Added new files (for test):

  • t/workflow.perl
  • t/workflow_action.perl
  • t/workflow_condition.perl
  • t/workflow_errorprone.perl
  • t/workflow_validator.perl

• Added POD to Workflow::Config::Perl on parse method

• Added CVS id keywords and author information to README

• Added CVS id keywords and author information to .txt files in doc

lib/Workflow/Persister/DBI.pm:

• fix dumb typo that resulted in PostgreSQL getting a random-ID generator instead of a sequence-ID generator, thanks to Michael Graham for pointing it out

0.16 2005-11-29

• META.yml

  • RT:12360: Added 'no_index' section so demo modules don't get indexed; thanks to Adam Kennedy for report and fix.

• lib/Workflow.pm:

  • RT:14413: Added workflow object to Workflow::State->get_autorun_action_name() call; thanks to Jonas Nielsen for report and fix.

• lib/Workflow/Factory.pm:

  • RT:12361: Add documentation about return values/exceptions from add_config() and add_config_from_file(); thanks to Adam Kennedy for report.

• lib/Workflow/Persister/DBI.pm:

  • POTENTIAL BACKWARD INCOMPATIBILITY:

  • Change 'user' field in history table to 'workflow_user' so we don't collide with PostgreSQL reserved word. (It's probably reserved elsewhere too...) If you have existing workflow tables you'll want to ALTER them to the new fieldname or look at the next changeitem to customize the field names.

  • Make the workflow and history fields settable by subclassing the persister -- just define 'get_workflow_fields()' and 'get_history_fields()' and return the names you want in the order specified in the docs. Thanks to Michael Graham for the nudge.

  • Be sure to pass in the database handle to the pre_fetch ID generator in create_workflow() (related to RT:15622)

  • RT:15622: While we didn't apply this patch we did cleanup some of the similar code....

  • Apply patch from Frank Rothhaupt to work with Oracle sequences.

• lib/Workflow/Persister/DBI/SequenceId.pm:

  • Throw proper exception if we cannot execute the sequence SQL.

0.15 2004-10-17

• CPAN/Install notes:

  • You should now be able to reference the Workflow module via CPAN with 'install Workflow' and such. Thanks to Michael Schwern (RT bug #8011) and the PAUSE indexing server for the reports.

  Also thanks to Michael Roberts for releasing the 'Workflow' namespace to this module. If you're interested in workflows I strongly encourage you to check out his wftk (Workflow Toolkit) project along with the Perl interface when it's released.

• Build.PL/Makefile.PL:

  • Add Class::Factory as dependency. Thanks to Michael Schwern for the pointer via RT:8010) -- during my presentation to pgh.pm on the Workflow module no less! (I added a reference to the presentation in README and Workflow.pm)

  • Add Class::Observable as dependency for new functionality.

• eg/ticket/ticket.pl:

  • Ensure we actually delete the SQLite database file if it exists.

• t/TestUtil.pm:

  • Always store the logfile from testing in the 't/' directory.

• Workflow:

  • Workflows are now observable. Big thanks to Tom Moertel tmoertel@cpan.org for the suggestion. See WORKFLOWS ARE OBSERVABLE in docs.

  • In previous versions most properties were read-only but it wasn't enforced. Now it is.

• Workflow::Factory:

  • Add the ability to register observers from the 'workflow' configuration and add them to workflows created from fetch_workflow() and create_workflow(). Configuration information available in Workflow.pm.

0.10 2004-10-12

• Workflow

  • POTENTIAL BACKWARD INCOMPATIBILITY

    • Since we've now got 'resulting_state' in a state's action that is dependent on the action results of the previous action being run (see Workflow::State change), we cannot set the 'new' workflow state before executing the action.

    • One result: you shouldn't set the 'state' property of any created Workflow::History objects -- we'll modify the state of any history objects with an empty state before saving them (see changes for Workflow::Factory)

    • Another result: the value of '$wf->state' inside your Action now refers to the EXISTING state of the workflow not the SOON TO BE state. Earlier versions had the SOON TO BE state set into the workflow before executing the action to make things less confusing. Now that it's changed any code you have using the state of the workflow (such as in our example 'Trouble Ticket' application in eg/ticket/) will give a different value than the previous Workflow version.

    • This behavior seems more consistent, but comments/suggestions are welcome.

  • In 'execute_action()' -- once we're done executing the main action, check to see if our new state is an autorun state, and if so run it.

• Workflow::Action::Null

  • New class: use if you want to move the workflow from one state to another without actually doing anything.

• Workflow::Condition::Evaluate

  • New class: allow inline conditions expressed as Perl code in the 'test' attribution of 'condition'; has access to the values in the current workflow context in a Safe compartment.

• Workflow::Factory

  • In save_workflow(), call 'set_new_state()' with the workflow state on all unsaved Workflow::History objects before saving them.

• Workflow::State

  • Add 'autorun' property and 'get_autorun_action_name()' to retrieve the single valid action name available from an autorun state.

  • The 'resulting_state' property of an action within a state can now be multivalued, which means the next state depends on the return value of the action that's executed. For instance, we might have:

     <state name="create user">
         <action name="create">
           <resulting_state return="admin"    state="assign as admin" />
           <resulting_state return="helpdesk" state="assign as helpdesk" />
           <resulting_state return="*"        state="assign as luser" />
         </action>
        ....
  

  • So if the action 'create' returns 'admin', the new state will be 'assign as admin'; on 'helpdesk' it will be 'assign as helpdesk', and all other values will go to state 'assign as luser'.

  • Existing behavior (actions returning nothing for a single 'resulting_state') is unchanged.

• Workflow::Persister::DBI

  • Trying to fetch a workflow with a non-existent ID didn't work properly, returning an empty workflow object (which blew up when you tried to call a method on it) instead of undef (as documented). Thanks to Martin Winkler mw@arsnavigandi.de for pointing the problem out.

  • Add CGI interface ('ticket.cgi') to example application, and move most of the logic into App::Web, which is now a full object instead of a bunch of class methods. Both the standalone web server ('ticket_web.pl') and the CGI script use the same logic, templates, template processing, etc.

• Workflow::Config

  • Move Perl/XML configuration parsers to separate classes and make this class a factory.

  • Add class method 'parse_all_files()' to allow you to pass in a list of mixed-type files (some XML, some Perl) and have them be parsed properly.

  • Add documentation about implementing your own configuration reader

• Workflow::Config::Perl

  • New class: code moved from Workflow::Config for perl-only parsing

• Workflow::Config::XML

  • New class: code moved from Workflow::Config for XML-only parsing

• Workflow::Factory

  • Invoke class method in Workflow::Config to deal with potentially different types of configuration (e.g., mixing and matching 'xml' and 'perl' files).

• Workflow::Persister::DBI::AutoGeneratedId:

  • Fix typo bug spotted by Martin Winkler (winkler-martin@web.de)

• Applied modified patches from Jim Smith (jgsmith@tamu.edu) to do the following:

  • Allow you to read in the XML/Perl configuration file from somewhere else and pass it to Workflow::Config as a scalar reference.

  • You can subclass Workflow::Factory and still use 'FACTORY' to import the factory of the class you want and 'instance()' to do the same.

• Added docs for these new features, and added tests for at least the factory subclassing feature.
