PanAfriL10n - PmWiki - DebugVariables

A custom function name replacing the built-in Abort() function.

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.

displays a list of all markups in 4 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)
  • column 4 = Debug backtrace information for potentially incompatible rules (filename, line number, pattern)
(see Custom Markup Using the Markup() function for custom wiki syntax; migration to PHP 5.5 ).
To see more than what ?action=ruleset gives you, apply the Cookbook:MarkupRulesetDebugging recipe: it can also show the pattern and the replacement strings.
  • doesn't make use of PmWiki's authorization mechanisms.

displays the output of phpinfo() and exits. No page will be processed
  • doesn't make use of PmWiki's authorization mechanisms.

displays a dump of all global vars and exits. No page will be processed
  • doesn't make use of PmWiki's authorization mechanisms.
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.
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:StopWatchHTML 1--> 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.
See Stopwatch for more details.

Is it possible for someone with admin priviledges to always have access to debugging tools, without letting everyone else access them?

You can easily & automatically allow debugging for anyone with admin priviledges (meanwhile leaving it off for everyone else) by including this line in config.php - just be sure that 1) $EnableDiag is either null or set to 0, and 2) to include it near the end of config.php, AFTER declaring your passwords, and after any AuthUser or other priviledge settings:

if (CondAuth($pagename, 'admin')) $EnableDiag = 1; # allows admin to always call phpinfo, etc
