Detailed Description

Custom implementation of iXHProfRuns.

This class is one implementation of the iXHProfRuns interface, in charge of storing and retrieve profiling run data to/from DB (profiling table)

The interface only defines two methods to be defined: get_run() and save_run() we'll be implementing some more in order to keep all the rest of information in our runs properly handled.

Member Function Documentation

get_run()

moodle_xhprofrun::get_run	(		$run_id,
			$type,
		&	$run_desc )

Given one runid and one type, return the run data and some extra info in run_desc from DB.

Note that $type is completely ignored

Implements iXHProfRuns.

reduce_run_data()

moodle_xhprofrun::reduce_run_data ( array $info )

protected

Reduce the run data to a more manageable size.

This removes from the run data all the entries that are matching a group of regular expressions.

The main use is to remove all the calls between "__Mustache" functions, which don't provide any useful information and make the call-graph too complex to be handled.

Parameters

array

$info

The xhprof run data, original array.

Return values

array

The xhprof run data, reduced array.

save_run()

moodle_xhprofrun::save_run	(		$xhprof_data,
			$type,
			$run_id = null )

Given some run data, one type and, optionally, one runid store the information in DB.

Note that $type is completely ignored

Implements iXHProfRuns.

set_reducedata()

moodle_xhprofrun::set_reducedata

(

bool

$reducedata

)

Enable or disable reducing profiling data.

Parameters

bool

$reducedata

Decide if we want to reduce profiling data (true) or no (false).

xhprof_topo_sort()

moodle_xhprofrun::xhprof_topo_sort ( array $info )

protected

Sort the xhprof run pseudo-topologically, so all parents are always before their children.

Note that this is not a proper, complex, recursive topological sorting algorithm, returning nodes that later have to be converted back to xhprof "pairs" but, instead, does the specific work to get those parent==>child (2 levels only) "pairs" sorted (parents always before children).

Parameters

array

$info

The xhprof run data, original array.

Return values

array

The xhprof run data, sorted array.
