Item13510: Configure is incorrectly applying $FALSE and $TRUE defaults from Config.spec files

After installing AntiWikiSpamPlugin, the setting {CheckAttachments} ends up enabled in the configuration.

• Config.spec value is $Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{CheckAttachments} = $FALSE;
• Initial install log:

> Installed: 9 files copied; 0 filed checked in, 0 files attached
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{CheckTopics} = undef;
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{CheckAttachments} = undef;
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{CheckRegistrations} = undef;
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{MeaningfulWebs} = '.*';
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{IgnoredTopics} = '^(UserRegistration|WikiUsers|Web.*)$';
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{MeaningfulCount} = 10;
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{ANTISPAMREGEXLISTURL} = 'http://arch.thinkmo.de/cgi-bin/spam-merge';
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{LOCALANTISPAMREGEXLISTTOPIC} = '$Foswiki::cfg{SystemWebName}.AntiWikiSpamLocalList';
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{AutoUpdateSignatures} = undef;
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{GETLISTTIMEOUT} = 60;
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{BypassGroup} = 'AntiWikiSpamBypassGroup';
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{HitThreshold} = 1;
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{RegistrationWhiteList} = '$Foswiki::cfg{SystemWebName}.AntiWikiSpamRegistrationWhiteList';
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{RegistrationBlackList} = '$Foswiki::cfg{SystemWebName}.AntiWikiSpamRegistrationBlackList';

• LocalSite.cfg after installation:

grep AntiWikiSpamPlugin lib/LocalSite.cfg | grep undef
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{AutoUpdateSignatures} = undef;
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{CheckAttachments} = undef;
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{CheckRegistrations} = undef;
$Foswiki::cfg{Plugins}{AntiWikiSpamPlugin}{CheckTopics} = undef;

• Visit to bin/configure in web:
  • Initially no changes shown in [Save] button
  • Visit the Plugins->AntiWikiSpamPlugin tab, and it immediately jumps to 4 pending changes:

        {Plugins}{AntiWikiSpamPlugin}{CheckTopics}
        {Plugins}{AntiWikiSpamPlugin}{CheckAttachments}
        {Plugins}{AntiWikiSpamPlugin}{CheckRegistrations}
        {Plugins}{AntiWikiSpamPlugin}{AutoUpdateSignatures}

• Save changes the 4 undefined (default to $FALSE) to true.

  {Plugins}{AntiWikiSpamPlugin}{AutoUpdateSignatures}    ($FALSE)    1
  {Plugins}{AntiWikiSpamPlugin}{CheckAttachments}    ($FALSE)    1
  {Plugins}{AntiWikiSpamPlugin}{CheckRegistrations}    ($TRUE)    1
  {Plugins}{AntiWikiSpamPlugin}{CheckTopics}    ($TRUE)    1

Marking this urgent because applying incorrect defaults during initial installation, and then changing them to other incorrect values via the web interface could cause serious issues.

-- GeorgeClark - 06 Jul 2015 AntiWikiSpamPlugin has had the $FALSE / $TRUE removed. But also recreate with HomePagePlugin. Specifically $Foswiki::cfg{HomePagePlugin}{GotoHomePageOnLogin}

• Initial configuration is $Foswiki::cfg{HomePagePlugin}{GotoHomePageOnLogin} = 0;
• Run installer: tools/extension_installer HomePagePlugin install
• Configuration changed to: $Foswiki::cfg{HomePagePlugin}{GotoHomePageOnLogin} = undef;
• View configuration with bin/configure: {HomePagePlugin}{GotoHomePageOnLogin}: is checked as enabled, and there is one pending change for save:
• Save configuration:

{HomePagePlugin}{GotoHomePageOnLogin}

($FALSE)

1

So after an extensions update, the current configuration is changed from 0, to undef, to 1, in sequence.

Simple fix. $FALSE and $TRUE need to be defined in Foswiki::Configure::Package
