nodejs/node#3111 - v8BreakIterator disablement #4253

Getting this going… need to rebase

srl295 · 2015-12-12T01:35:34Z

Rebased. Problem, it doesn't actually work. My changes to src/node.js Don't seem to have effect after rebase.

OK, it's working again. Can I get a LGTM?

srl295 · 2016-04-09T02:42:32Z

To test:
node -e 'new Intl.v8BreakIterator()'

before: crashes in small-icu (which is our default)
after: no crash

$ ./node -e 'new Intl.v8BreakIterator()'
internal/process.js:72
        throw Error('Data not available...'); 
        ^
Error: Data not available...

add test

Question: what's the best way to test this?

bnoordhuis · 2016-04-09T10:29:30Z

lib/internal/process.js

@@ -65,6 +65,13 @@ function setupConfig(_source) {
    if (value === 'false') return false;
    return value;
  });
+  if ( process.config.variables.v8_enable_i18n_support && global.hasOwnProperty('Intl') 


Style error: space after (. Can you put each check on its own line, followed by the &&? You'll also need to start with:

if (process.config && process.config.variables && // ...

Thanks. I'll drop the check for process.config.variables.v8_enable_i18n_support also. For this code's purpose, checking Intl is enough. One fewer dependency on an internal v8 variable is better.

srl295 · 2016-04-11T16:33:12Z

Updated, PTAL

bnoordhuis · 2016-04-11T16:48:09Z

lib/internal/process.js

+  // 
+  if (global.hasOwnProperty('Intl') &&
+      Intl.hasOwnProperty('v8BreakIterator') &&
+      process.config.variables.icu_small &&


You still need a process.config && process.config.variables feature check here and can you make sure make lint passes?

srl295 · 2016-04-11T17:47:56Z

linter happy
test updated

bnoordhuis · 2016-04-11T18:56:26Z

lib/internal/process.js

+  // Intl.v8BreakIterator() would crash v8 with a nastygram here, throw instead.
+  if (global.hasOwnProperty('Intl') &&
+      Intl.hasOwnProperty('v8BreakIterator') &&
+      process.config.variables.icu_small &&


Needs a process.config && process.config.variables feature check.

srl295 · 2016-05-03T21:39:34Z

Updated, rebased. Thanks @jasnell

If the undocumented v8BreakIterator does not have data available, monkeypatch it to throw an error instead of crashing. Fixes nodejs#3111

LGTM if CI is green :-)

@srl295 this does not land cleanly on v4.x would you be willing to manually backport?

srl295 · 2016-06-01T22:23:05Z

Yes. Probably an earlier version would. Or maybe depend on back porting the other process change @jasnell ?
