    1531There are some significant "warts" in this; such as accepting a ticket sets it to 'assigned' state, and assigning a ticket sets it to 'new' state.  Perfectly obvious, right? 
    16 So you will probably want to migrate to "basic" workflow; `contrib/workflow/migrate_original_to_basic.py` may be helpful.

    27 There are several example workflows provided in the Trac source tree; look in `contrib/workflow` for `.ini` config sections.  One of those may be a good match for what you want. They can be pasted into the `[ticket-workflow]` section of your `trac.ini` file.

They can be pasted into the `[ticket-workflow]` section of your `trac.ini` file. However if you have existing tickets then there may be issues if those tickets have states that are not in the new workflow.  
     60 
     61Here are some [http://trac.edgewall.org/wiki/WorkFlow/Examples diagrams] of the above examples.

    2963== Basic Ticket Workflow Customization == 
     64 
     65Note: Ticket "statuses" or "states" are not separately defined. The states a ticket can be in are automatically generated by the transitions defined in a workflow. Therefore, creating a new ticket state simply requires defining a state transition in the workflow that starts or ends with that state. 
    3066 
    3167Create a `[ticket-workflow]` section in `trac.ini`. 
     
    4884 - del_resolution -- Clears the resolution field 
    4985 - set_resolution -- Sets the resolution to the selected value. 
    50    - ''actionname''`.set_resolution` may optionally be set to a comma delimited list or a single value. 
    51 {{{

    59 }}} 
     93     }}} 
    6094 - leave_status -- Displays "leave as <current status>" and makes no change to the ticket. 
    6195'''Note:''' Specifying conflicting operations (such as `set_owner` and `del_owner`) has unspecified results. 
     
    90124And then open up the resulting `trac.pdf` file created by the script (it will be in the same directory as the `trac.ini` file).

     127 
    92128After you have changed a workflow, you need to restart apache for the changes to take effect. This is important, because the changes will still show up when you run your script, but all the old workflow steps will still be there until the server is restarted.

     148=== How to combine the `tracopt.ticket.commit_updater` with the testing workflow === 
     149 
     150The [[trac:source:trunk/tracopt/ticket/commit_updater.py|tracopt.ticket.commit_updater]] is the optional component that [[TracRepositoryAdmin#trac-post-commit-hook|replaces the old trac-post-commit-hook]], in Trac 0.12. 
     151 
     152By default it reacts on some keywords found in changeset message logs like ''close'', ''fix'' etc. and performs the corresponding workflow action. 
     153 
     154If you have a more complex workflow, like the testing stage described above and you want the ''closes'' keyword to move the ticket to the ''testing'' status instead of the ''closed'' status, you need to adapt the code a bit.  
     155 
     156Have a look at the [[trac:wiki:0.11/TracWorkflow#How-ToCombineSVNtrac-post-commit-hookWithTestWorkflow|Trac 0.11 recipe]] for the `trac-post-commit-hook`, this will give you some ideas about how to modify the component. 
     157 
     158== Example: Add simple optional generic review state == 
     159 
     160Sometimes Trac is used in situations where "testing" can mean different things to different people so you may want to create an optional workflow state that is between the default workflow's `assigned` and `closed` states, but does not impose implementation-specific details. The only new state you need to add for this is a `reviewing` state. A ticket may then be "submitted for review" from any state that it can be reassigned. If a review passes, you can re-use the `resolve` action to close the ticket, and if it fails you can re-use the `reassign` action to push it back into the normal workflow. 
     161 
     162The new `reviewing` state along with its associated `review` action looks like this: 
     163 
     164{{{ 
     165review = new,assigned,reopened -> reviewing 
     166review.operations = set_owner 
     167review.permissions = TICKET_MODIFY 
     168}}} 
     169 
     170Then, to integrate this with the default Trac 0.11 workflow, you also need to add the `reviewing` state to the `accept` and `resolve` actions, like so: 
     171 
     172{{{ 
     173accept = new,reviewing -> assigned 
     174[…] 
     175resolve = new,assigned,reopened,reviewing -> closed 
     176}}} 
     177 
     178Optionally, you can also add a new action that allows you to change the ticket's owner without moving the ticket out of the `reviewing` state. This enables you to reassign review work without pushing the ticket back to the `new` status. 
     179 
     180{{{ 
     181reassign_reviewing = reviewing -> * 
     182reassign_reviewing.name = reassign review 
     183reassign_reviewing.operations = set_owner 
     184reassign_reviewing.permissions = TICKET_MODIFY 
     185}}} 
     186 
     187The full `[ticket-workflow]` configuration will thus look like this: 
     188 
     189{{{ 
     190[ticket-workflow] 
     191accept = new,reviewing -> assigned 
     192accept.operations = set_owner_to_self 
     193accept.permissions = TICKET_MODIFY 
     194leave = * -> * 
     195leave.default = 1 
     196leave.operations = leave_status 
     197reassign = new,assigned,accepted,reopened -> assigned 
     198reassign.operations = set_owner 
     199reassign.permissions = TICKET_MODIFY 
     200reopen = closed -> reopened 
     201reopen.operations = del_resolution 
     202reopen.permissions = TICKET_CREATE 
     203resolve = new,assigned,reopened,reviewing -> closed 
     204resolve.operations = set_resolution 
     205resolve.permissions = TICKET_MODIFY 
     206review = new,assigned,reopened -> reviewing 
     207review.operations = set_owner 
     208review.permissions = TICKET_MODIFY 
     209reassign_reviewing = reviewing -> * 
     210reassign_reviewing.operations = set_owner 
     211reassign_reviewing.name = reassign review 
     212reassign_reviewing.permissions = TICKET_MODIFY 
    110213}}} 
    111214 
     
    132235But if even that is not enough, you can disable the !ConfigurableTicketWorkflow component and create a plugin that completely replaces it.

    138245If you have a response to the comments below, create an enhancement ticket, and replace the description below with a link to the ticket. 
     
    142249   * '''postops''': automatic, when leaving the state/activity 
    143250   * '''actions''': can be chosen by the owner in the list at the bottom, and/or drop-down/pop-up together with the default actions of leaving the node on one of the arrows. 
    144 This appears to add complexity without adding functionality; please provide a detailed example where these additions allow something currently impossible to implement.

     254''A workflow plugin can add an arbitrary workflow operation, so this is already possible.'' 
    148255 
    149256 * set_actor should be an operation allowing to set the owner, e.g. as a "preop":

    151258   * entered fix at define time, or at run time, e.g. out of a field, or select. 
    152 This is either duplicating the existing `set_owner` operation, or needs to be clarified. 
     259''This is either duplicating the existing `set_owner` operation, or needs to be clarified.'' 
    153260 
    154261 * Actions should be selectable based on the ticket type (different Workflows for different tickets) 
    155 This is becoming a frequent request, with clear usecases.  The closest the current implementation will allow is to have a plugin provide a `triage` action that sets the next state based on the ticket type, so a `new` ticket would move to `new_task`, `new_defect`, etc., and the workflow graph would separate at that point. 
     262''Look into the [http://trac-hacks.org/wiki/AdvancedTicketWorkflowPlugin AdvancedTicketWorkflowPlugin]'s `triage` operation.'' 
     263 
     264 * I'd wish to have an option to perform automatic status changes. In my case, I do not want to start with "new", but with "assigned". So tickets in state "new" should automatically go into state "assigned". Or is there already a way to do this and I just missed it? 
     265''Have a look at [http://trac-hacks.org/wiki/TicketCreationStatusPlugin TicketCreationStatusPlugin] and [http://trac-hacks.org/wiki/TicketConditionalCreationStatusPlugin TicketConditionalCreationStatusPlugin]'' 
     266 
     267 * I added a 'testing' state. A tester can close the ticket or reject it. I'd like the transition from testing to rejected to set the owner to the person that put the ticket in 'testing'. The [http://trac-hacks.org/wiki/AdvancedTicketWorkflowPlugin AdvancedTicketWorkflowPlugin] is close with set_owner_to_field, but we need something like set_field_to_owner. 
     268 
     269 * I'd like to track the time a ticket is in each state, adding up 'disjoints' intervals in the same state.
