Summary0020682: Workflow transitions not consistent with bug action "change status to"

When configuring a status that has no "outbound" status, this is, in workflow configuration, there is no other status marked as allowed to move to.

In practice, this means that any transition, from this status to any other, is allowed (this probably is implemented for not locking an issue in a dead end status)

However, in view_bug, even if the transition is possible, the option for "change status to" is not present.

I'd rather have the possibility to configure a status that cant be transitioned into any other.
Some use cases for this:

  • A closed/archived status, that I intentionally want to not be modified
  • A special status that is managed by a plugin. I dont want the standard workflow to be able to change this status, it only will be transitioned by the plugin functionality

Note that these use cases are not satisfied by the options "Minimum Access Level to Change to this Status", becasue they'd need to be "changing FROM this status"

Additionally: A status without a transitions row, which is defaulted to all transitions, it still shows:
"You cannot move an issue out of this status"
In manage_config_workflow_page.php

Any opinions on this?
I am having several issues, as part of developing complex plugins, by needing some strict configurations. And this issue is blocking the consistence of these.

IMO, transistions should comply strictly to the workflow settings:
a status withouth any outbound status configured, should not allow transitions.

This seems like a breaking change and may confuse users when all of a sudden they are not able to do things that they were able to do before. So it may be worth exploring other options.

One option is to enable plugins to filter the valid target statuses for an issue. This may be dependent on plugin logic, issue details beyond status, etc.

Se the attached screenshot for a bug in such status.
The change status control is not showed.
The status may be changed by group actions though, as that shows all status (regadless of workflow settings)

So one issue, is that the status selector should be available, according to current logic.

A secondary issue, but no less important:
There is no way to configure a status that has no valid transitions.

The empty option check was introduced here: 0014013

regarding defaults:
"By default, there is no workflow defined, which means that all states are accessible from any other, by anyone."

This is from config_defaults_inc
$g_status_enum_workflow = array().

Note this inconsistency again:
manage_config_workflow_page.php, for the default array(), shows all status checked. If saved, a local config is created with the filled matrix, even if no change is made.

I suggest setting this semantics:
1) IF status_enum_workflow == array() RETURN true
This means all transitions are valid, to keep this default working.

2) If any row is not set
Keep this check, for the case where new status are introduced, and still not updated in the config matrix
if ( !isset( $t_status_enum_workflow[$p_bug_status] ) ) {
return true;

  • However, manage workflow page should show this case as a row with all status checked, same logic as (1)

3) make the workflow config save an empty array if no status are checked, so tha:
there exists a row $t_status_enum_workflow[$p_bug_status] (which is empty)
MantisEnum::hasValue( $t_allowed_states, $p_wanted_status ) returns false naturally

I have tested that hardcoding status_enum_workflow[STATUS] = ''
works in my expected way, where no transitions are allowed

Updated description with another inconsistency:

A status without a transitions row, which is defaulted to all transitions, it still shows:
"You cannot move an issue out of this status"
In manage_config_workflow_page.php

with the changes.

It does not break current configurations and behaviour.

Committer: dregad Details Diff
Modify empty and default cases for workflow configuration

Fix several inconsistencies with the treatment of status_enum_workflow

1. Fix showing a non existant status row in workflow config array. This
is interpreted as if that status allows all transitions, but in the
config page, the checks were shown unmarked, which can be confusing.
Now the checks appear marked in this situation.

2. As consequence of (1), the message "You cannot move an issue out
of this status" is not show anymore in that situation.

3. When a status row is saved with all transitions unchecked, an empty
enum string is saved, meaning effectively that no transitions are
allowed from that status. This specific configuration was previously
unavailable from the workflow config page.
