https://chromium-review.googlesource.com/c/chromium/src/+/1111818 : chromium canary

Some test failures are expected and are due to CLDR data changes. 

Others are unexpected and requires investigation. 

SpecialCasing failure is reported upstream: 
http://bugs.icu-project.org/trac/ticket/13851

The update is blocked by that bug. 

The above ICU bug was resolved. There are a few more failures to investigate and take care of. 

One of them is bug 856113. I put a work-around for the latest PS in the CL above. 

 issue v8:7825  (v8 side of ICU udpate) has more information, too. 

The following revision refers to this bug:

[regexp] Remove exhaustive Script_Extensions tests

The upstream test suite for Unicode property escapes [1] is exhaustive
and is updated soon after every new release of the Unicode Standard.
It is then upstreamed into Test262.

This patch simplifies our own Script_Extensions tests and the script
used to generate them. Now, only a few code points are tested for each
Script_Extension. This avoids unnecessary friction every time ICU
is updated based on a new Unicode version.

Now we're down to a few test failures related to bug 856947. Because bug 856947 is not likely to be fixed soon, I'll come up with a temporary work around. 

v8 trybots all pass except for node.js bot. The cause for that is known (node.js has its own copy of ICU and node.js bot fails to build Node when there's a version mismatch between v8's ICU and node's ICU). 

Down to these tests. They're all related to bug 856947.

locales now use "European" digits by default in Chromium's ICU to match
the behavior of other Google products. The CLDR upstream is expcted to
follow suit soon.

* Blink's homegrown grapheme cluster breakiterator is partly updated
per UAX 29 (text segmentation) in Unicode 11. (see crbug.com/856947)

* Whitespaces are kept together by a new word breaking rule (
 http://unicode.org/reports/tr29/#WB3d ). Update the test to reflect
 that change.

* Fix the currency formatting code in payment to handle better cases
with a space (U+00A0 / U+0020) between a currency code and a numeric
value (e.g. "-USD 47.37" in en-AU for USD).  A test was added to
CurrencyAmounts/PaymentsCurrencyFormatterTest.IsValidCurrencyFormat for
a negative value.

For Chromium, it's fixed. 
v8 roll is blocked by Node.js issue. I'll mark this as closed. Node.js issue will be resolved when Node.js updates its ICU.  v8 in Chrome browser will have ICU 62.1. 

bug 856947 does not block this any more.
