Detailed Description

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

Definition at line 36 of file Profiler.php.

Constructor & Destructor Documentation

◆ __construct()

Profiler::__construct ( array $params )

Parameters

array $params See $wgProfiler.

Reimplemented in ProfilerXhprof, ProfilerSectionOnly, and ProfilerExcimer.

Definition at line 56 of file Profiler.php.

References $params.

Member Function Documentation

◆ close()

Profiler::close ( )

abstract

Close opened profiling sections.

Reimplemented in ProfilerXhprof, ProfilerStub, ProfilerSectionOnly, and ProfilerExcimer.

◆ getAllowOutput()

Profiler::getAllowOutput ( )

Whether appending profiles is allowed.

Since: 1.34

Returns: bool

Definition at line 298 of file Profiler.php.

References $allowOutput.

◆ 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 272 of file Profiler.php.

References $header.

◆ getContext()

Profiler::getContext ( )

Access: internal

Returns: IContextSource

Since: 1.25

Definition at line 146 of file Profiler.php.

References RequestContext\getMain(), and wfDeprecated().

◆ 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 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
