Attempting to use plot-timer-events to generate a graph of v8.log

python2.7 required

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

export PATH=pwd/depot_tools:"$PATH"

fetch v8

[hf@archT440 v8]$ du -s -h
1.6G

node -p process.versions.v8

git branch --remotes | grep branch-heads/

git checkout branch-heads/5.0

cd v8/

gclient sync

tiny hack 1:
cd /usr/lib/
sudo ln -s libtinfo.so.6 libtinfo.so.5

tiny hack 2:
vim Makefile
GYPFLAGS += -Dlinux_use_bundled_gold=0
[ inspired by :https://bbs.archlinux.org/viewtopic.php?pid=1610923#p1610923 ]

make native

export D8_PATH=pwd/out/native/

[hf@archT440 v8]$ tools/plot-timer-events --distortion=4500 ~/isolate-0x23d4dc0-v8.log
line 0: undefined variable: Infinity

It works with v8.log generated by d8

Is the outcome of this issue a document, blog post, etc...?

I think shifting to "unscheduled" for now make sense.

Great move.

• The outcome is a document on entente.
• This is not part of our javascript layer tasks, so no plans for this.
