About multi-threading in V8

[Luc]

Hello,

How multi-threading works on V8 engine. Is it needed to use different
contexts or can we share object between different thread safely ?
What kind of precautions should we take when embedding V8 engine in an
heavy multi-threaded application ?

Regards,

Luc

There's a section in include/v8.h which explains the mechanisms.
Search for 'Locker'. Basically, V8 can use multiple threads, but only
one at a time, so you cannot have Javascript actually executing on
more than one CPU at a time unless you have several processes.

I try to explain what I knew. The only mechanism V8 provides is the Locker class which has a StartPreemption function. Most internal data of V8 are not thread-safe. So I'd say it is co-operative multi-threading. Gears in Chrome uses V8 in the multi-threading environment.

Just like CPython's GIL .
