Detailed Description

Profiler wrapper for XHProf extension.

$wgProfiler['class'] = 'ProfilerXhprof';
$wgProfiler['flags'] = XHPROF_FLAGS_NO_BUILTINS;
$wgProfiler['output'] = 'text';
$wgProfiler['visible'] = true;

$wgProfiler['class'] = 'ProfilerXhprof';
$wgProfiler['flags'] = XHPROF_FLAGS_CPU | XHPROF_FLAGS_MEMORY | XHPROF_FLAGS_NO_BUILTINS;
$wgProfiler['output'] = 'udp';

ProfilerXhprof profiles all functions using the XHProf PHP extenstion. For PHP5 users, this extension can be installed via PECL or your operating system's package manager. XHProf support is built into HHVM.

To restrict the functions for which profiling data is collected, you can use either a whitelist ($wgProfiler['include']) or a blacklist ($wgProfiler['exclude']) containing an array of function names. Shell-style patterns are also accepted.
