check out automatic locking in the c++ wrapper of spidermonkey, sorry I
forgot the api names but they are fairly simple to find out.
Then, your bottleneck isn't javascript anymore (unless somebody can prove me
wrong! :)

For some reason, my email address is being blocked by the moderator so 
the list is not getting this mail.   The problem with v8 threading is 
really simple.


1.  Google V8 only allows one context to execute at a time.
2.  If you are using multiple context design, they must be executed 
using exactly the same thread via a single event loop.


Failure to do this will result to a corrupt stack.

The one that usually gets us on embedded scripts is the garbage collector.
They tend to use a global one and it can cause all kinds of blocking when
objects are tied to host objects like calls and waiting for them to
terminate holds up things.

Can you have 1 context per thread the same way we do it now in the other
languages?
lua has a similar limitation but we just start a whole lua interpreter per
thread/script.

Re: [Freeswitch-dev] TraceMonkey

2010-07-01 Thread Jan Berger 
Will find out tomorrow - I see threading in the code. 

It might be a case on how they do the threading. This is after all a VM even
if they use native code - meaning they might do the threading in the VM. In
which case you actually run it from a single thread, but you don't need to
thread V8 itself - it's the scripts you run that must be threaded -
something a VM can do internally.

Take into account that a CISC like x86 have to move a load of register cash
every time it actually thread - so simulating threading in the VM - changing
context between 2 instructions would be a very performance saving thing to
do. 

But, I will find out more exact tomorrow because I am only guessing now -
and this is rather critical. 

V8 compiles to a 128 mb library :/ on Windows ...

I thought V8 was designed to be multi-threaded from inception.  Maybe I
am confusing my projects.  I wonder if it was the embedding part of it
that did not enable proper threading ???   Then again it could be like
python, where when embedded all threads are virtual to the 1 process
that is running (ie not threads as far as the kernel is concerned) which
can confuse the kernel scheduler into sticking it in the penalty box for
a while.  Normally you are not doing enough in the embedded language to

Re: [Freeswitch-dev] TraceMonkey

2010-07-01 Thread Jan Berger 
So in short - if a call executes a long script the other calls will be
queued unable to process events - V8 is a joke as a scripting environment if
you can't create multiple environments. 

 

I kind of see a poor IVR developer that accidentally made an ever loop and
the entire companies phone system is down :-)

 

Obviously - I can get around it using several processes, but processes are
bloody expensive on any OS.

I have been using Google V8 for nearly a year now in one of our commercial
SIP product offerings and it scales quite well.   The only gotcha so far is
that google V8 contexts do not go well with a multi threaded environment.
That would force application design to always use async-IO.   One good proof
of this all async project is node.js.

http://nodejs.org/

I think it would also be a good idea to integrate this project into
free-switch which would instantly give free-switch access to a vast number
of JS API including sockets and HTTP client.

my 2 cents.

Subject: [Freeswitch-dev] TraceMonkey

 

Hi,

 

Was searching for updated JavaScript alternatives and found this
Tamarin/TraceMonkey. Do anyone have experience with this version? They claim
a 5-10 x speed increase compared to the older SpiderMonkey

 

"Tamarin is a JavaScript <https://developer.mozilla.org/en/JavaScript>
engine written in C++. It currently implements Adobe ActionScriptT 3 (a
superset of ECMAScript Edition 3) and is embedded within the AdobeR FlashR
Player versions 9 and later.  Tamarin's jit-compiler,  NanoJIT, is also used
in TraceMonkey <https://wiki.mozilla.org/JavaScript:TraceMonkey>  ergo
SpiderMonkey, which is Mozilla's JavaScript engine in Firefox.

Re: [Freeswitch-dev] TraceMonkey

2010-07-01 Thread Bret McDanel 
I thought V8 was designed to be multi-threaded from inception.  Maybe I
am confusing my projects.  I wonder if it was the embedding part of it
that did not enable proper threading ???   Then again it could be like
python, where when embedded all threads are virtual to the 1 process
that is running (ie not threads as far as the kernel is concerned) which
can confuse the kernel scheduler into sticking it in the penalty box for
a while.  Normally you are not doing enough in the embedded language to
notice this scheduler issue so its almost a moot point.  Other points
may be valid though.
