Detailed Description

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

Definition at line 37 of file Profiler.php.

Constructor & Destructor Documentation

◆ __construct()

Profiler::__construct ( array $params)
Parameters
array$paramsSee $wgProfiler.

Reimplemented in ProfilerExcimer, ProfilerSectionOnly, and ProfilerXhprof.

Definition at line 55 of file Profiler.php.

References $params.

Member Function Documentation

◆ close()

Profiler::close ( )
abstract

Close opened profiling sections.

Reimplemented in ProfilerExcimer, ProfilerSectionOnly, ProfilerStub, and ProfilerXhprof.

◆ getAllowOutput()

Profiler::getAllowOutput ( )

Whether appending profiles is allowed.

Deprecated
since 1.41. Unused.
Since
1.34
Returns
bool

Definition at line 284 of file Profiler.php.

References wfDeprecated().

◆ 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 256 of file Profiler.php.

References $header.

◆ 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

Reimplemented in ProfilerExcimer, ProfilerSectionOnly, ProfilerStub, and ProfilerXhprof.

◆ getOutput()

Profiler::getOutput ( )
abstract

Returns a profiling output to be stored in debug file.

Returns
string

Reimplemented in ProfilerExcimer, ProfilerSectionOnly, ProfilerStub, and ProfilerXhprof.

◆ getProfileID()

Profiler::getProfileID ( )
Returns
string

Definition at line 126 of file Profiler.php.

◆ getTransactionProfiler()

Profiler::getTransactionProfiler ( )
Returns

◆ instance()

◆ logData()

Profiler::logData ( )

Log data to all the applicable backing stores.

Definition at line 227 of file Profiler.php.

◆ scopedProfileIn()

Profiler::scopedProfileIn ( $section)
abstract

Mark the start of a custom profiling frame (e.g.

DB queries). The frame ends when the result of this method falls out of scope.

Parameters
string$section
Returns
ScopedCallback|null
Since
1.25

Reimplemented in ProfilerExcimer, ProfilerSectionOnly, ProfilerStub, and ProfilerXhprof.
