                    line);

                if (match):
-                        klass = match.group(1);
+                        klass = match.group(1).rstrip().lstrip();


I have to ask: why not just .strip()?

Looking back on it, that is what it probably should have been...

weird, looks like only arm and windows builds ran?

evanlucas · 2015-11-14T02:19:44Z

ok, trying CI again https://ci.nodejs.org/job/node-test-pull-request/726/

rvagg · 2015-11-14T02:22:20Z

@joaocgreis same problem as yesterday, something's up with Jenkins, perhaps it's more complicated than just a wonky freshness detection?

evanlucas · 2015-11-14T02:24:50Z

I guess I'll hold off on landing until we get it sorted out?

rvagg · 2015-11-14T02:27:07Z

Yes please @evanlucas, also @nodejs/collaborators please note that CI is not currently doing full runs, until you get a full run passing for your tests you won't have full assurance that your changes can land. The @nodejs/build team is working on resolving this but we're fighting with Jenkins on this and it's a bit like playing wac-a-mole while riding a bucking bull.

evanlucas · 2015-11-14T02:28:04Z

Cool. Thanks. Let me know if I can help in any way :]

I'm going to add LTS watch to this and backport it when we do the next batch

@nodejs/collaborators last chance to veto

jasnell · 2016-03-11T00:42:16Z

@nodejs/lts

rvagg · 2016-03-14T01:45:30Z

looks OK to me for LTS I think, would love input from @nodejs/post-mortem wrt v4 support for this and how much it actually matters.

MylesBorins · 2016-03-17T17:23:46Z

perhaps @mhdawson has some thoughts

davepacheco · 2016-03-22T16:21:27Z

What's the question with respect to postmortem?

@davepacheco if this should be backported to v4

davepacheco · 2016-04-18T20:57:35Z

I'm not aware of postmortem tools that use JSMap or JSSet. If those are the only affected classes, I don't think this would matter. But then, I don't know how anybody would have noticed in the first place, so maybe something does use these? Or maybe there's some other metadata that's affected?

(Edited to clarify I was talking about JSMap, not Map.)

mhdawson · 2016-04-18T21:57:36Z

@thealphanerd the IBM tools don't currently use that port mortem data so not needed from that perspective. I know that @yunong does use the mdb port mortem tools and mentioned above that he'd like this to be landed so maybe he can comment on the need to backport.

evanlucas · 2016-04-18T21:59:32Z

I noticed it when using llnode.

MylesBorins · 2016-04-18T22:02:57Z

ping @indutny re: llnode

indutny · 2016-04-19T15:10:17Z

llnode doesn't really have support for this, at least not yet. +0 from me

MylesBorins · 2016-05-17T22:30:01Z

@nodejs/collaborators does anyone have an interest in this being backported?

indutny · 2016-05-17T23:08:34Z

Not me.

jasnell · 2016-05-17T23:21:38Z

hmm.. I'm +0 on it I think.
