Hi,
I'm experiencing a segfault when using
SnapshotCreator::FunctionCodeHandling::kKeep. I'm wondering if this is
intended behavior or a bug?
Here is a patch to demo it in test/cctest/test-serialize.cc
https://gist.github.com/ry/0429eb4887370ee2a263446a59ec9ed7
thank you,

Jakob, I'm glad to hear that your v8_base is only 29M for you. The .o files
in my obj/v8_base are large

Could this have something to do with libcpp_is_static?

Hi,
I've noticed that the build size in the latest V8 releases is very large.
For example, on 6.5.257, I get
-rw-r--r-- 1 rld staff 1.1G Feb 7 18:49 out/v8build/obj//libv8_base.a
It's similarly large on 6.6.164. I'm experiencing this on OSX and here is
the configuration I'm using:
https://github.com/joyent/node/commit/b68c6bac96a480fe210220335bc685e89a927d2b
It seems v8_base depends on ws2_32.lib for accept() and some of the
other socket used for the debugger.

Hi,
In Node we call a function EventEmitter.prototype.emit very often:

Hi,
Do you know if is there an effort for binding v8 with the gnome libraries
through gobject-instrospection? Such as seed [1] for jscore, or gjs [2] for
spidermonkey.
Thanks

2.
Would it be feasible to somehow core dump a V8 context and inspect
it post-mortem with the debugger agent?

Which server are you refering to?
The debugger agent. It would be nice to be able to call
i::Debugger::StopAgent() from the protocol.

Ryan,
This sounds like a reasonable request. The new heap profiler can generate a
JSON representation of a heap snapshot, so that would fit straight into the
debugger protocol. However this JSON string have a size which could easily
be the same

Finally I have found the solution.
1. The alternative version of constructor jsnative_myobj() should be
used (it is commented out in the code in my previous post above).
2. Persistent handles are created using Persistent::New(). So, the

Hi,
When I issue a scripts command to the debugger agent, I don't get a
complete list of script that have been compiled. I guess this is
because they have been garbage collected and that the
scriptCollected event which accompanies the result is a reference to
those collected scripts. My question
Hi Søren,
I'm began a little patch to give such a wake-up callback (attached).
Is this something you all would accept?
It adds a new public function v8::Debug::Poll() which is to be called
from the main thread occasionally. It also adds an optional third
argument to v8::Debug::EnableAgent()
Hi Søren,
If you receive a message in the DebuggerAgent and your main thread is
not immediately executing javascript but idling in select(), how can
you give control back to V8 to handle the message? It seems there
should be some way to poll the agent to handle received messages.
Am I correct
Hello -
I am trying to store binary in a string by using an
ExternalAsciiStringResource. There is a problem with values over 127.
It seems this might be solved a some cast somewhere inside of V8? Or
is it more complicated than that? The problem is shown with the
attached C++ program.

There still seems to be no way to get a stack trace - at least not in
1.2.14. PrintCurrentStackTrace doesn't work either after the exception

this was disabled for performance reasons - is there a way one could
re-enable it?
How do I use the debugger agent? I'm running

Any guidance from the V8 dev team ?

I'm experiencing an error trying to build bleeding_edge with
snapshot=on on Linux.
It doesn't give a very informative error message, just Error -11.
Any ideas?

The result will be empty if an exception occoured. You can use a stack
allocated v8::TryCatch in C++ to catch exceptions.
Take a look at the test FunctionCall in test/cctest/test-api.cc.
Which is better: checking if the return value is empty or using
try_catch.HasCaught() ?
Also a shot in the dark: Does the callback get executed as part of
the normal execution or is it like a signal handler? (I know nothing
about windows)
