inspector Record Allocation Timeline bugged

[Somebi]

Ubuntu 16.04
Node.js v7.4.0
tried first on Google Chrome Version 54~
then on latest beta Google Chrome Version 57.0.2987.37 beta (64-bit)

node --trace_gc --max_old_space_size=5000 --inspect /var/local/bot/gather_all.js

chrome-devtools://devtools/bundled/inspector.html?experiments=true&v8only=true&ws=127.0.0.1:9229/8743459a-0079-47f3-a8c0-2493fd56c3ca

Is that a chrome dev tools bug or bug is somewhere inside node.js or even inside v8, not sure...

But the results should be like this:

Timeline doesn't have anything inside it...

Maybe i'm doing something wrong?

Added versions in initial post, will try with some of the latest nodes, maybe with master branch too. Will try to compile from sources.

--max_old_space_size=5000

It not work correctly. See #10185 Fixes in #10186 node v7.5.0

[Somebi]

I have tried this in v7.5.0 still doesn't work. Will try without --max_old_space_size argument.

I'm experiencing this as well. The timeline is just empty but it has a summary. Node v7.5.0

If it helps

1. I run the script with node --inspect --debug-brk
2. Start Record Allocation Timeline
3. Go to Sources and resume execution
4. When it is done, I go back to Profiles and stop recording.

Still doesn't work in Node v7.8.0

It may be an issue in Chrome. I just tried with Node v6.10.1 and it didn't work.

[Somebi]

Too bad, this was a great feature. Well it's still experimental feature as i understand. Hope it will reach stable release.

Same problem here.
Note that the other profile recorders work fine

Is there any movement on this? v8.1.3 still does not have the timeline working properly.

I guess cc/ @nodejs/v8-inspector

Please open a bug against Chrome DevTools. Node provides the profiling data (as you can see from a table beneath the chart).

Nope, I was wrong - there are issues both on the DevTools and on the Node sides. I am reopening this.
