32baff5906 perf: Use var for METRICS
Each perf module exposes it to the scripting module to report metrics
after all tests have been run. The symbol's scope should allow that,
so declare it as var.

46575804cc perf: Stop using legacy generator functions
This was a non-standard Mozilla extension that is no longer supported.
Simply switch to the standardized generator syntax to fix.

213e38c2ef cleanup: Use arrow notation for anonymous functions
Arrow notation is great, use it consistently through-out the code base
to bind `this` to anonymous functions, replacing the more overbose
Lang.bind(this, function() {}).

e30925995f Make frame-timestamp logging optional
Instead of always logging frame timestamps for every frame - which
was using >26 bytes of memory per frame, or 5MB per hour of continuous
redrawing - make frame timestamps something that defaults off and is
turned turned on using a new ShellGlobal::frame-timestamps property by
the perf scripts.

f285f2c69f Scripting.createTestWindow(): take params
Take a parameter object rather than a long parameter list containing
multiple booleans.

37da87d9e1 perf: Update to latest overlay changes
Removing tabs from the overview broke the perf test for the
application view; update test to the new method of bringing
it up.

e756c2dbce js: use System.gc() instead of shell_global_gc()
gjs now offers a gc() method in the System module, no need to use our
own.

75b824d032 *.js: Make emacs modelines consistent
js2-mode is no longer developed and we recommend js-mode these days,
so switch the modelines to specify that, and make them consistent
across all files.

80a9d2e7c9 overview: Make viewSelector private
It's only used internally by the overview itself,
and by some performance testing code, so don't
expose it as a public object.

windows view the first time and the second time.

239aa7b8d5 perf: Add metrics for different window configurations
Add metrics:
 overviewFps5Windows
 overviewFps10Windows
 overviewFps5Maximzed
 overviewFps10Maximized
 overviewFps5Alpha
 overviewFps10Alpha

To have more numbers to show how performance varies with different
numbers of windows and different types of windows (maximized,
with an alpha channel.)

821583acae Use gnome-shell-perf-helper to control windows during perf tests
* Run gnome-shell-perf-helper during performance tests
* Use MUTTER_WM_CLASS_FILTER to omit all other windows
* Add new Scripting methods: createTestWindow,
  waitTestWindows, destroyTestWindows
* Create a single 640x480 test window for testing overview
  animation performance.

15dd1164b7 [perf] replace frame count with accurately computed frame rate
Compute a frame rate for the period between:

 - User sees first frame of overview animation
 - User sees fully zoomed-out overview

And replace the current Frames count metrics with this. The
previous frame count metrics were actually over the period from
the start of the animation until the window labels finished
animating in; here we are careful to look at a more restricted
period.

20d579e7d8 Add units to metrics definitions
Switch from having separate METRICS and METRIC_DESCRIPTIONS objects
in a perf module to a single METRICS array. This is done so the
perf module can define the units for each metric.

In addition to improving the output in the web interface, the purpose
of having units is to give some clue about how to pick from multiple
values from different runs. In particular, with the assumption that
"noise" on the system will increase run times, for time values we want
to pick the smallest values, while for "rate" values, we want to pick
the largest value.

08b8b39a5d Add simple malloc statistics and metrics
Add some basic statistics for allocated memory based on mallinfo(),
and use that to define two metrics:

 usedAfterOverview: bytes used after the overview is shown once
 leakedAfterOverview: additional bytes used when the overview is
   shown a second time.

98c2247c1b Add a facility for automated performance measurement
We want to be able to summarize the behavior of the shell's
performance in a series of "metrics", like the latency between
clicking on the Activities button and seeing a response.

This patch adds the ability to create a script under perf/
in a special format that automates a series of actions in the
shell, writing events to the performance log, then collects
statistics as the log as replayed and turns them into a set
of metrics.

The script is then executed by running as gnome-shell
--perf=<script>.

The 'core' script which is added here will be the primary
performance measurement script that we use for shell performance
regression testing; right now it has a couple of placeholder
metrics.
