Detailed Description

Profiler base class that defines the interface and some shared functionality.

Definition at line 33 of file Profiler.php.

Constructor & Destructor Documentation

◆ __construct()

Profiler::__construct ( array $params )

Parameters

array $params See $wgProfiler.

Reimplemented in ProfilerXhprof, ProfilerExcimer, and ProfilerSectionOnly.

Definition at line 51 of file Profiler.php.

References $params.

Member Function Documentation

◆ close()

Profiler::close ( )

abstract

Close opened profiling sections.

Reimplemented in ProfilerXhprof, ProfilerExcimer, ProfilerSectionOnly, and ProfilerStub.

◆ getAllowOutput()

Profiler::getAllowOutput ( )

Whether appending profiles is allowed.

Since: 1.34

Returns: bool

Definition at line 325 of file Profiler.php.

References $allowOutput.

Referenced by getTemplated().

◆ getContentType()

Profiler::getContentType ( )

Get the Content-Type for deciding how to format appended profile output.

Disabled by default. Enable via setAllowOutput().

See also: ProfilerOutputText

Since: 1.25

Returns: string|null Returns null if disabled or no Content-Type found.

Definition at line 277 of file Profiler.php.

References $header.

◆ getContext()

Profiler::getContext ( )

Gets the context for this Profiler.

Returns: IContextSource

Since: 1.25

Definition at line 138 of file Profiler.php.

References $context, RequestContext\getMain(), and wfDebug().

Referenced by logData().

◆ getFunctionStats()

Profiler::getFunctionStats ( )

abstract

Get the aggregated inclusive profiling data for each method.

The percent time for each time is based on the current "total" time used is based on all methods so far. This method can therefore be called several times in between several profiling calls without the delays in usage of the profiler skewing the results. A "-total" entry is always included in the results.

When a call chain involves a method invoked within itself, any entries for the cyclic invocation should be be demarked with "@". This makes filtering them out easier and follows the xhprof style.

Returns

array[] List of method entries arrays, each having:

name : method name
calls : the number of invoking calls
real : real time elapsed (ms)
real : percent real time
cpu : CPU time elapsed (ms)
cpu : percent CPU time
memory : memory used (bytes)
memory : percent memory used
min_real : min real time in a call (ms)
max_real : max real time in a call (ms)

Since: 1.25
