Instead of maintaining a mapping of short names to class names ('db' =>
'ProfilerOutputDb', etc.), let us adopt the convention of using the full
class name to indicate the output type. We can maintain backward-compatibility
by using simple string manipulation to transform short names to the full class
names.

* Associate Profiler objects with a request context by adding a $context
property with a getter and a setter.
* Introduce ProfilerOutputStats, which writes profiling data to the stats
buffer associated with the current request context.
* Make it the Profiler class's responsibility to enforce $wgProfilerLimit.
* Deprecate $wgProfilerLimit in favor of the (more aptly named, IMO)
$wgProfiler['threshold'] config setting.
* Tidy up Profiler instance creation code in Profiler::instance().
* Add Profiler::getOutputs, which returns an array of ProfilerOutput instances
which are configured for the current profiler and whose canUse() method
returns true.
* Make ProfilerStub not log by creating a stub ProfilerStub::logData() method
which does not call the parent. Previously the parent class checked if $this
was an instance of ProfilerStub and returned early if so.

* This can happen well over 10k times per request due to the message
hooks. Avoiding the object construction seems prudent.

We've already broken profiling completely in this release. Make
this abundantly clear in the RELEASE-NOTES and just remove the
awful back-compat attempt from I2af28cd3 and I49c0a83e.

* Made use of it in the DatabaseBase classes
* For the xhprof class, this only works in HHVM for now
Change-Id: I95d7cc128d4a770328fbdd2b546972d3fc2e2e8a
* Added a standard getFunctionStats() method for Profilers to return
per function data as maps. This is not toolbar specific like getRawData().
* Cleaned up the interface of SectionProfiler::getFunctionStats() a bit.
* Removed unused cpu_sq, real_sq fields from profiler UDP output.
* Moved getTime/getInitialTime to ProfilerStandard.

Creates absurd dependency on the profiler from the parser. This profiling
is also not compatible with function-level profiling that we're trying to
aim for with xhprof.
Change-Id: I3c780fcb06e3470a0cbf50311ba916a0b67ea49e
Add a helper class to assist in collecting profiling information using
XHProf <https://github.com/phacility/xhprof> and a Profiler
implementation to hook it into the existing MediaWiki profiling system.
The Profiler includes support for generating tabular reports similar to
the traditional output of ProfilerSimpleText and ProfilerSimpleTrace or
sending data to a udpprofile daemon as supported by ProfilerSimpleUDP.
It also produces data compatible with the debugging toolbar.

This is a weird construction that only existed for dumpHTML.
DumpHTML will no longer require this as of Ia38aa904.
It won't work with future plans to separate profiling & profiling
output

- Put Profiler, ProfileSection and TransactionProfiler in their own
files and rely on Autoloader to use them (maintenance has been
using the autoloader here for some time--we don't profile the
autoloader manually)
- This reduces overhead in WebStart/doMaintenance by only loading
three functions at profiler initialization and defers until the
first profiling call happens
- Inline callback functions in ProfilerSimpleText rather than having
public static functions.
- Small comment and code formatting changes in various touched files.

As of <https://github.com/facebook/hhvm/commit/0f98cab>, it is possible to
call getrusage( [ int $who = 0 ] ) with $who = 2 to request resource usage
info for the current thread (RUSAGE_THERAD), rather than the calling process
(RUSAGE_SELF). (Earlier versions of HHVM return RUSAGE_SELF data unless $who
is 1.)
PHP5 code can assume that each request is handled in a dedicated subprocess,
but the same is not true of HHVM, which is multi-threaded. Therefore, to get
resource usage data for the current request context, it is necessary to ask
for RUSAGE_THREAD rather than RUSAGE_SELF.
To do this, introduce a new global function in Profiler.php: wfGetRusage().
It is defined there and not in GlobalFunctions.php so that it can be used early
in WebStart.php.

- Swap "$variable type" to "type $variable"
- Added missing types
- Fixed spacing inside docs
- Makes beginning of @param/@return/@var/@throws in capital
- Changed some types to match the more common spelling

* Replaced use of spl hash with random transaction IDs.
These can be correlated better and make the DBPerformance
log easier to make sense of. They are also shorter.
Change-Id: I5f49c0d0c26e37807341bbc83b1b41b124164419
Swapped some "$var type" to "type $var" or added missing types
before the $var. Changed some other types to match the more common
spelling. Makes beginning of some text in captial.
Also added some missing @param.

* Factored a ProfilerStandard class out of Profiler
* Profiler is now an abstract base class
* For b/c, using Profiler as the profiler switches to ProfilerStub
to avoid trying to instantiate an abstract class
* Also factored out a small TransactionProfiler class
* Fixed fatal in "new ProfilerStub()" line in getInstance();
Profiler has long since type hinted $params as an array
* Removed bogus debug var usage left in ProfilerMwprof::getRawData()
* Removed useless mTimeMetric stuff

* Merged the "collate at end" and "running collate" logic
into the base class to make it more unified and consistent.
* Pulled out DB code into ProfilerSimpleDB class.
* Removed the ProfilerSimple class and updated child classes.
* Made ProfilerSimpleTrace set the debug information too.
* Work around "ended by close()" bug from 99aef03f. Since the
getRawData() method gets called while some wfProfileOut() calls
have not yet happened, make it use the matched call data and let
the final logData() method work on the full data as normal.
* Let ProfilerSimple classes use getFunctionReport() for the profiler
debug log if it is setup instead of making it just return "".
* Made getRawData() work as best as possible with ProfilerMwprof.
* Removed $wgProfileToDatabase since it is now useless.
* Improved DB profile performance with sqlite.
* Updated visibility of various methods.

This adds a new pane for the debug toolbar labeled Profiler. It groups
together events sent to wfProfileIn/Out and draws a timeline giving a
visual representation of what the page was doing at a particular point
in time. Hovering over a timeline brings up a flyout about the contained
events.
Depends on I08854d80f57286129f19cb14566f84ed3c7fa21c for proper positioning
of the flyout.

Easier to catch them than if they are in the default debug log.
Added Profiler::debugGroup() as wrapper to wfDebugLog(), as
there already is Profiler::debug() for wfDebug(), so that
there won't be a fatal error if the error happens before the
inclusion of GlobalFunctions.php and converted other calls
to wfDebugLog() to use it.

The Line continuation Coding conventions prefers the closing parenthesis
on the same line than the beginning curly braces. This is done for ifs
and functions.
Also move some boolean operator from the end of a line to the beginning
and changed some indentation to make the condition hopefully better
readable.
Change-Id: Id0437b06bde86eb5a75bc59eefa19e7edb624426
Also removed some unnecessary ones. I think I've caught them all.
The spaceless version already appears in core ~300 times (after
accounting for false positives when grepping). Some consistency would
be nice.
