Bug 187973

relative_test_filename of chromium_win.py used to replace backward slash with forward slash. (Bug 34739)

test_name has been cannibalized in unix-style since Bug 63597.

Basuke's Bug 179572 seems bad fix.

Bug 180660, too.

WIP patch

* Reverted parts of Bug 179572, Bug 180660 and Bug 181814 to restore test_name is unix-style.
* relative_test_filename: Replace os.path.sep with self.TEST_PATH_SEPARATOR.
* abspath_for_test: Replace self.TEST_PATH_SEPARATOR with os.path.sep.

This patch makes some tests of test-webkitpy failing because 
common/system/filesystem_mock.py assumes path separator is a forward slash.

> python Tools\Scripts\test-webkitpy webkitpy.port.base_unittest.PortTest.test_test_exists

This is the test case to check mock file system.

This seems the reason why chromium_win.py didn't do the string conversion in abspath_for_test.

WIP patch

This patch significantly reduces the number of test-webkitpy failures, but LayoutTest doesn't work.

FAILED (failures=41, errors=25)
↓
FAILED (failures=0, errors=8)

If DumpRenderTree is given a file path containing forward slashes, such like:

> C:\webkit\ga\LayoutTests\fast/css/button-height.html

CFURLCreateWithFileSystemPath converts it to "file://localhost/C:/webkit/ga/LayoutTests/fast%2Fcss%2Fbutton-height.html".

I am currently observing errors on the Win EWS bots. Is it possible that this was introduced by this change? This is the error message:

It looks like https://trac.webkit.org/changeset/234749/webkit has caused the perf tests on Sierra to all fail. 

Build History:

Reverted r234749 for reason:

This patch alsodoesn't solve my original issue. The test result is still displayed using Windows path. Something is missing.

Oh, it was rolled back. That's why.

Looks like perf tests use abspaths as test names, so we need to be explicit and `.replace(self.TEST_PATH_SEPARATOR, self.host.filesystem.sep)` here.
