The first step in this process was to set up the FYI bots, which are now set up; so far, this has revealed to us that we need more work before Windows works with --enable-wptserve.

Current state of the FYI bots can be seen at:

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/489b7e668259f3e433af13eae79a018bc78beca1

commit 489b7e668259f3e433af13eae79a018bc78beca1
Author: qyearsley <qyearsley@chromium.org>
Date: Wed Jun 29 23:40:11 2016

Rename functions in Port related to wptserve and add a helper function.

This is a refactoring CL which should cause no behavior changes.

In this CL:
 (1) Rename is_wpt_enabled -> is_wptserve_enabled
 (2) Rename is_wpt_test -> is_wptserve_test
 (3) Add should_use_wptserve (= is_wptserve enabled and is_wptserve_test).

The rational for (2) is that many (most) tests in imported/wpt behave the
same if they're run with wptserve and with file://; only a smallish number
of the tests behave differently. It may be faster to run the tests if we
only use wptserve for the tests that require it; so later we may want
to change is_wptserve_test to check some things, e.g. wptserve header
files in the directory; or ".http." or ".https."  in the file name.

wptserve: Don't use copies of testharnessreport.js and vendor-prefix.js.

wptserve has the alias feature, and we can map files in LayoutTests/resources/
to web-platform.test/{common,resources}/* without copying.

Revert of wptserve: Enable WPTServe by default. (patchset #1 id:1 of https://codereview.chromium.org/2482793002/ )

Reason for revert:

I'm reverting this because I think

imported/wpt/html/browsers/history/the-location-interface/reload_post_1.html

started failing with the switch on windows, see

https://build.chromium.org/p/chromium.webkit/builders/WebKit%20Win7%20%28dbg%29/builds/8056

and I'm the sheriff today.

However, I'm also concerned that I think you missed my comments in #10. I don't think a 30% cycle time regression is okay,
at least not without an explanation and a plan for addressing it.

Looks enabling WPTServe didn't cause any issues except the slight performance degradation.  I'll start code cleanup.

Revert of wptserve: Enable WPTServe by default. (patchset #1 id:1 of https://codereview.chromium.org/2497193002/ )

Reason for revert:
I suspect that the startup/shutdown logic in wptserve is not right, and we're seeing intermittent failures where we're hanging trying to start wptserve.

See crbug.com/669194 and https://build.chromium.org/p/chromium.webkit/builders/WebKit%20Mac10.11/builds/13447/steps/webkit_tests/logs/stdio for an example.

I'm speculatively reverting this for now, to see if things become happier.

Alright, I think the next step is to try relanding the enabling of wptserve by default again, right? Some test expectations will have to be updated, but maybe the easiest way to handle that is to make the reland CL, try layout tests, and then modify TestExpectations (and possibly download some new baselines?) in that same CL.

tkent@, does that sound like the right way?

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/b39b2b6850398acf84f8bb86038dce754bf778d8

commit b39b2b6850398acf84f8bb86038dce754bf778d8
Author: tkent <tkent@chromium.org>
Date: Fri Jan 20 07:57:54 2017

Cleanup after enabling WPTServe.

* webkitpy/layout_tests and LayoutTests/WPTServeExpectations
  Remove --enable_wptserve flag and related code.

* webkitpy/w3c and other files
  Stop copying testharnessreport.js, WebIDLParser.js, and vendor-prefix.js.
  We map LayoutTests/resources/{testharnessreport.js,vendor-prefix.js} into
  external/wpt by 'alias' feature of WPTServe. So we don't need to copy these
  files any longer.
  As for WebIDLParser.js, WPTServe maps /resources/WebIDLParser.js to
  /resources/webidl2/lib/webidl2.js by default [1]
  csswg-test doesn't use WPTServe, and we need to update blink_test_runner.cc
  so that /resoruces/testharness*.js point files in LayoutTests/resources.

I think there are no remaining tasks for this.

Amazing! Thanks tkent.

Just confirmed with tkent: only external/wpt is running wptserve by default now. I'll change the summary to reflect that. I think the remaining work for all LayoutTests is tracked at issue 347864.
