Debug Variables

<< Basic Variables | PmWiki.Variables | Edit Variables >>

$EnableDiag

the following actions are available only if you set $EnableDiag = 1 in your configuration file. They can be used for debugging and should not be set in a production environment.

?action=ruleset

displays a list of all markups in 3 columns:

• column 1 = markup-name (1. parameter of markup() )
• column 2 = when will rule apply (2. parameter of markup() )
• column 3 = PmWiki's internal sort key (derived from #2)

?action=phpinfo

displays the output of phpinfo() and exits. no page will be processed

?action=diag

displays a dump of all global vars and exits. no page will be processed

$EnableIMSCaching

A variable which, when set equal to 1, recognizes the "If-Modified-Since" header coming from browsers and allows browsers to use locally cached pages. Disabled by default to help the administrator customize its page without needing permanent reloading.

$EnableStopWatch

This activates an internal stopwatch that shows how long it takes to render a page. (If you have a wiki that composes a HTML page from multiple pages, such as a normal layout with a sidebar, you'll get separate timings for each subpage and for the total page.)

The timings can be displayed by adding <!--function:StopWatch--> in the wiki template.

Valid values are:

        $EnableStopWatch = 0; # No timings (the default). No HTML will be generated.
        $EnableStopWatch = 1; # Wall-clock timings only.
        $EnableStopWatch = 2; # Wall-clock and CPU usage timings. Won't work on Windows.
