Convenience class for working with XHProf profiling data https://github.com/phacility/xhprof.
getCriticalPath( $metric='wt')
Find the critical path for the given metric.
pruneData( $data)
Remove data for functions that are not included in the 'include' configuration array.
getInclusiveMetrics()
Get the inclusive metrics for each function call.
$inclusive
Per-function inclusive data.
static makeSortFunction( $key, $sub)
Make a closure to use as a sort function.
getCallees( $function)
Get a list of all callees from a given function.
getRawData()
Get raw data collected by xhprof.
$hieraData
Hierarchical profiling data returned by xhprof.
__construct(array $data, array $config=[])
Configuration data can contain:
$complete
Per-function inclusive and exclusive data.
getCallers( $function)
Get a list of all callers of a given function.
static splitKey( $key)
Convert an xhprof data key into an array of ['parent', 'child'] function names.
getCompleteMetrics()
Get the inclusive and exclusive metrics for each function call.
deferred txt A few of the database updates required by various functions here can be deferred until after the result page is displayed to the user For updating the view updating the linked to tables after a etc PHP does not yet have any way to tell the server to actually return and disconnect while still running these but it might have such a feature in the future We handle these by creating a deferred update object and putting those objects on a global list
Allows to change the fields on the form that will be generated $name
Returning false makes less sense for events where the action is complete
